Workflow of screw press p>
The screw press is an auxiliary equipment for the pollution-retaining grille. It is composed of a feeding hopper, a pressing screw, a spiral pipe, a slag discharge pipe and a driving device. The grid slag or filtered slag picked up by the grid enters the spiral tube from the feeding hopper, and is squeezed and dehydrated under the action of the pressing screw. The water permeable filter screen extruded from the material is collected into the water receiving basin and discharged through the drain pipe. After the material is compressed, it is discharged through the slag discharge pipe, which can greatly reduce the weight and volume of debris such as screen slag. The screw press consists of a drainage area, a feeding area, a screw conveying area and a discharging area. The grid slag enters the material area, and the grid slag is discharged after being compacted in the compaction area by the screw press, and the waste liquid flows from the grid bars into the water collecting pipe.
What are the characteristics of the screw press
1. The use of shaftless screw, small contact surface with the material, low friction, can improve the extrusion efficiency . And no blockage, no winding phenomenon;
2. The equipment is made of stainless steel, with high strength, good corrosion resistance and long service life;
3. The drive device adopts shaft-mounted direct drive
4. The outlet is equipped with a spring baffle to increase the extrusion force and improve the dehydration rate;
5. Except for the inlet and outlet, the rest Adopting a sealed structure, the use environment is clean and hygienic.
The scope of application of the screw press
1. It is used to intercept the sewage grille in the water supply and drainage pump station, sewage treatment plant and water works
2. Dehydration and compression of grid slag or filter slag in the treatment of industrial wastewater such as papermaking, sugar making, winemaking, food processing, slaughtering, leather, textile, printing and dyeing, petrochemical, etc. .
Daily maintenance and maintenance methods of screw press
1. Before use, use cleaning fluid to clean the contact parts of the equipment and materials.
2. When the pressing work is nearing the end and needs to be shut down, do not stop the machine directly. First, reduce the pressure of the hydraulic system so that the material residue after pressing and dehydration pushes the forcing door at the end of the screen barrel open; or lift the forcing door by manual operation, and then let the machine continue to operate for a period of time until the material residue in the screen barrel Can not continue to discharge the forced door, and then shut down, and clean up the remaining material residue in the screen barrel.
3. Try to avoid excessive pressure during the operation of the machine, otherwise it will cause the machine to stop suddenly or the screen barrel ruptures and other failures.
4. The oil temperature of the hydraulic system should not exceed 60℃. Since the temperature of the hydraulic pump rises rapidly at high pressure, it is recommended that the oil pump work continuously at high pressure for no more than 30 minutes. The temperature rise of each bearing in the transmission system shall not exceed 40°C at room temperature.
5. Do not let sharp, hard objects and metal objects enter the machine during the operation of the machine. They will damage the parts in the machine and affect the normal operation of the machine. Pick it out.
6. If the machine is not used for a long time, the material residue in the machine must be rinsed and cleaned with a water gun, and the rust-prone parts should be coated with grease for protection and placed in a ventilated and dry place.
7. The oil in the hydraulic system should be kept clean. When adding oil or changing the oil, the oil should be filtered with a 120-mesh filter.
8. The bearings of the transmission system should be regularly injected with grease for maintenance; the gearbox should be regularly injected with lubricating oil for maintenance; the hydraulic oil tank should be regularly injected with hydraulic oil for maintenance.
