[Single-machine dust collector] Working principle of single-machine dust collector: Precautions for installation of single-machine dust collector
What is the working principle of single-machine dust collector
The working principle of the stand-alone dust collector is that the dust-laden gas enters the box from the inlet of the dust collector, and is filtered through the filter bag. The dust is left on the inner surface of the filter bag. The purified gas enters the fan through the filter bag and is inhaled by the fan. Directly discharge into the room (can also take over and discharge to the outside). With the increase of filtration time, the dust adhered to the inner surface of the filter bag also increases, and the resistance of the filter bag increases, which affects the dust removal effect. Shake automatically for tens of seconds to shake off the dust sticking to the inner surface of the filter bag, and the dust falls to the ash hopper, drawer or directly to the conveyor belt.
Characteristics of a single-machine dust collector
A single-machine dust collector unit, a dust catcher is a kind of air purification equipment with small size and high dust removal efficiency. It is suitable for various independent dust generating points, flexible and convenient, on-site dust collection and on-site treatment, which can effectively ensure the cleanliness of the air. The basic structure consists of a dust removal box, a centrifugal fan, a filter bag (filter cartridge), a dust collector and a microcomputer controller. Coarse particle dust is pre-filtered by the filter and directly falls to the dust collector. The particulate dust is captured by the filter on the outer surface. The clean gas is filtered, decomposed and purified by the filter element and then flows into the clean room, and then is discharged from the air outlet by the fan. The entire dust removal and filtration process is the result of a comprehensive effect of gravity, inertial force, collision, electrostatic adsorption, and sieving.
The single-machine dust collector is used in industrial production, with small size, simple and convenient operation, low noise during operation, and ideal dust removal effect. In the pharmaceutical industry, in food manufacturing, and ceramic manufacturing, single-machine dust collectors can play a good role in that the dust removal efficiency can reach more than 90%, which has played a significant role in environmental protection.
Installation and precautions of single-machine dust collector
The single-machine dust collector is installed near the mechanical equipment that generates dust, and the user should follow the instructions on the dust collector. The size of the air inlet can be configured with metal or plastic dust ducts and dust hoods.
1. The electric control box cover of the stand-alone dust collector should not be opened at will during work. If you need to adjust the cleaning time or check the circuit, you should cut off the power after the machine is stopped and work.
2. According to the nature and capacity of the dust, the single-machine dust collector should be vibrated regularly to remove the dust. Generally, it should be vibrated three to four times per shift to ensure the normal operation of the dust collector.
3. The single-machine dust collector should regularly remove dust according to actual needs. When the dust in the dust collector is removed, it is only necessary to open the sealed dust outlet door and draw out the drawer when the fan and dust cleaning mechanism are stopped. That’s it.
4. In order to ensure that the dust removal equipment is in the best working condition, it should be as close as possible to the source of dust, generally 1.5m to 2.0m is the best, the connecting pipe should be as short as possible, and the elbow should be minimized to avoid increasing resistance loss.
5. The dust hood is a key accessory to ensure that the single-machine dust collector unit is in the best state. The user should be based on the size of the workpiece and the nature of the dust. The principle of vacuum hood, making the ideal vacuum hood.
6. Check whether the inspection door, dust outlet door, and air duct connection system are sealed before the stand-alone dust collector works, so as to avoid leakage and reduce the dust collection effect.
7. The voltage of the stand-alone dust collector is 380 volts of three-phase alternating current. It can be used after connecting the power supply from the external wire on the stand-alone dust collector. Turn (if reversed, the air volume is very small, the power wiring needs to be replaced).
