[Dry cleaning machine] Classification of dry cleaning machines Detailed explanation of the operation process of dry cleaning machines
Classification of dry cleaning machines
One It is an open dry cleaning machine;
The second is a fully enclosed dry cleaning machine. The difference is the drying recovery system.
Refrigeration dry cleaning machines are also known as fully enclosed dry cleaning machines. After the clothes are washed and deliquored, the drying and recovery of the residual solvent on the clothes is completed by a set of condensers. The cooling cycle of the refrigeration unit makes the residual solvent on the clothes quickly heated, vaporized, condensed, liquefied and recovered. Since the cooling temperature is lower than that of the water-cooled type, the drying and recovery cycle can be shortened, the solvent recovery rate is high, and the solvent consumption is about 1%. Therefore, at the end of drying, there is very little residual tetrachloroethylene vapor in the washing tub. , In some refrigeration dry cleaning machines, in order to further reduce the smell when taking clothes, an adsorber is installed at the outlet of the machine drying air duct to absorb tetrachloroethylene in the exhaust gas to meet the requirements of environmental protection.
The fifth-generation fully enclosed dry cleaning machine has activated carbon filtration, secondary recovery and automatic cleaning devices for distillation boxes. The third and fourth generations of closed dry cleaning machines, after the clothes are cooled and deodorized, the gaseous tetrachloroethylene concentration in the cylinder is at least 1500-2000PPM, while the fifth-generation machine can reduce the gaseous tetrachloroethylene concentration in the simplified air through the adsorption of the carbon adsorption system. To below 300PPM, open the door to take clothes at this time, the external discharge of tetrachloroethylene can be minimized, and the residual pollution degree in the simplified version specified by the international standard is ≤300PPM, and the surrounding environment is ≤25PPM. Some fifth-generation fully enclosed dry cleaning machines also have a desorption function. When a certain amount of tetrachloroethylene is adsorbed, the internal activated carbon tends to be saturated. At this time, the desorption system can be activated to regenerate the activated carbon and condense it into a gaseous solvent. Liquid recycling.
Dry-cleaning machine type differences
The difference in performance between perchloroethylene water-cooled recovery dry-cleaning machines and refrigeration dry-cleaning machines: water-cooled dry-cleaning machines are also known as open-type dry-cleaning machines Dry cleaner. After the clothes are washed and deliquored, the drying and recycling of the residual solvent on the clothes is carried out by a water-cooled cooler for cooling and recycling. Due to the high temperature of the cooling water, the recovery effect is relatively poor. After drying, in order to reduce the leakage of tetrachloroethylene when taking clothes, this type of dry cleaning machine has an exhaust air exhaust device, which can discharge the solvent gas remaining in the machine to the outside of the machine, so the consumption of solvent is relatively large. At the same time, it also caused some pollution to the environment.
1. The petroleum dry cleaning machine can wash clothes more comprehensively than the perchloroethylene dry cleaning machine. The petroleum dry cleaning machine can wash all fabrics except down jackets.
2. The price of petroleum dry cleaning machine is cheaper than that of perchloroethylene dry cleaning machine.
3. The cleanliness of petroleum washing machine is not as high as that of tetrachloroethylene. Only a simple pretreatment is required before dry cleaning with a tetrachloroethylene dry cleaning machine. Oil dry cleaning machines require laborious pretreatment, otherwise the oil stains on the clothes will definitely not be washed clean.
Types of dry cleaning machines
Dry cleaning machine models include SGX-8A, SGX-8, SGX-10, SGX-12 , SGX-15 type petroleum dry cleaning machine, tetrachloroethylene dry cleaning machine is divided into energy-saving dry cleaning machine and fully enclosed tetrachloroethylene dry cleaning machine, and the models of tetrachloroethylene dry cleaning machine are energy-saving GX-6 type, fully enclosed dry cleaning and dry cleaning. Machine GXZQ-8, GXZQ-10, GXZQ-12, GXZQ-15.
Double tank of petroleum dry cleaning machine means that there are two detergent storage tanks at the bottom of the dry cleaning equipment. The detergent recovered from washing dark clothes is stored in the dark tank, and the detergent recovered from washing light clothes is stored in the light tank, and the arrangement of the two storage tanks makes the laundry effect in a good state. The computer board design and route of the double-cylinder equipment are more rational and scientific. For clothes required by different standards, specific treatments, such as different treatments for dirty clothes, ordinary clothes, silk, etc. The double filter has the washing effect of double filtration, making the detergent clearer and the clothes cleaner.
Single tank means that there is only one detergent storage tank at the bottom of the dry cleaner. Even if the dark clothes and light-colored clothes are washed in batches and batches, the final detergent is still stored in the same tank, resulting in the mixing of two detergents with different requirements.
Reminder: Remind you to pay attention to the overall structure of the dry-cleaning machine when you open a dry-cleaning shop to buy a dry-cleaning machine, so as to avoid being shoddy by the manufacturer and causing you unnecessary losses.
Dry cleaning machine operation process
1. Fill the distillation tank with water before the first laundry every day
1. Method: Open the water filling valve and the water level valve, and add water from the water filling valve. When the water level valve flows out, it is proved that the water is full, and the water filling valve and the water level valve are closed.
Second, turn on the power, select the clothes and put them in the drum and close the door.
1. Open the liquid outlet valve of the rough washing box, and the drum enters the liquid valve, other valves are closed. From the computer board, turn on the liquid pump key, low speed key, distillation key, pump the liquid from the bottom tank into the drum, observe from the metal filter, when the liquid level reaches 3/4, open the drain valve, and close the coarse washing liquid Box valve for mainstream.
Three, Mainstream15-20minutes (self-mastery) to start draining
1 , Open the liquid valve of the rough washing tank, close the liquid inlet valve of the drum, observe from the front mirror and wait for the liquid to come out of the semi-closed liquid pump button, then open the liquid outlet valve of the rough washing tank at the back, open the high-speed button, enter and spin dry, 3 Automatically stop after minutes and then dry.
Fourth, start drying after high stripping
1. Open the drying button, the low speed button, and then open the drying steam inlet valve at the back, and dry Return steam valve, turn on the cooling water, start drying, the drying temperature is controlled by the drying steam inlet valve, if the temperature does not rise during drying, close the drying steam inlet valve and the drying return steam valve, and slowly turn on the steam inlet valve. Open the steam valve, open the drying steam inlet valve and the drying steam return valve after the steam is released (pay attention to safety). Observe whether there is dripping from the glass mirror of the water distribution tank. If there is no dripping, it proves that it has been dried, and then press The total stop button, open the door to take clothes, turn off the cooling water, close all the valves behind, and turn off the power.
Operating Specifications for Dry Cleaning Machines
1. Before using the dry cleaning machine every day, check its various switches, pipes, transmission belts, etc., and wipe the machine.
2. Turn on the main power switch, turn on the power switch in the machine, turn on the water supply switch and the compressed air switch.
3. Open the steam valve (half), press the control key of the drying steam solenoid valve and turn on the steam switch of the distillation cylinder at the same time, and then open the steam bypass valve for about 5-10 minutes. After the accumulated water in the internal heat exchanger is drained, fully open the steam valve and close the bypass valve at the same time. The steam solenoid valve control key is reset. Turn off the retort steam switch.
4. Check whether the function control keys on the panel work normally, and observe whether the pneumatic valves in the machine work normally.
5. The washing capacity of clothes and cloth is 70-80% of the designed capacity of the machine. For fluffy clothes, this cannot be used as a standard. It is measured by the normal movement of the drum in the machine when the clothes are soaked in dry cleaning solvent.
6. When using the control card, it should be light in and light out, and it should not be pulled hard. For manual operation, each button should be tapped lightly, and the action should not be too rapid.
7. The appropriate control card should be selected for the corresponding laundry. If the computer-controlled dry cleaning machine is used, select the appropriate program. It should be checked clearly before starting to avoid wasting time or even causing unintended consequences.
8. When washing by hand, attention should be paid to the time control and the adjustment of drying temperature during each step.
