Description

Pulse drawer dust collector

technical field

The utility model relates to the technical field of dust removal devices, in particular to a pulse drawer type dust collector.

Background technique

In the existing dust removal equipment, the dust-laden air enters the filter chamber of the dust collection equipment from the inlet of the dust collection equipment. Due to the slowing down of the wind speed, the heavier dust falls to the inner drawer; the lighter dust adheres to the On the surface of the filter bag, the clean air is pumped through the air outlet to the air outlet and discharged outside. The filter bag has accumulated a lot of dust, which is difficult to clean. It is necessary to remove the filter bag and clean it one by one, and then install it after cleaning. The treatment is very complicated.

Therefore, based on the defects of the above-mentioned existing dust removal devices, it is necessary to improve the existing dust removal devices.

Contents of the invention

The purpose of this utility model is to provide a pulse drawer type dust collector for the deficiencies of the prior art. The pulse drawer type dust collector solves the defects of the existing dust removal device: troublesome cleaning of filter bags, complicated operation and the like.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

Pulse drawer type dust collector, fan is installed on the cabinet body, dust collection drawer is installed at the bottom of the cabinet body, filter bag is installed in the cabinet body, the filter bag is located above the drawer, and there is a double air blowpipe above the filter bag, the cabinet body An air storage cylinder is installed on the outside, and the air storage cylinder is connected with a double air blowpipe.

Specifically, a solenoid valve is installed between the compound air blowpipe and the air storage cylinder.

The air storage cylinder is connected with an air compressor.

More specifically, there are multiple multiple air blowpipes, the multiple air blowpipes are arranged vertically to the filter bags, and the multiple air blowpipes are provided with blowing holes corresponding to the filter bags.

Further, the air storage cylinder and the solenoid valve are located outside the cabinet.

Furthermore, the filter bag is a polyester needle felt non-woven filter bag.

The composite air blowpipe is connected with a branch pipe corresponding to the filter bag, and the branch pipe extends into the filter bag.

The beneficial effect of the utility model is that: blowing air to the filter bag through the compound air blowing pipe causes the filter bag to expand and vibrate, so that the dust adhered to the surface of the filter bag falls off, that is, the effect of air backwashing the filter bag is achieved. The procedure is simple and easy to use. The effect is very good.

Description of drawings

Fig. 1 is a schematic cross-sectional view of a partial structure of the present invention.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

See Fig. 1, the utility model pulse drawer type dust collector comprises: cabinet body 1, blower fan 2, air storage cylinder 3, electromagnetic valve 4, compound air blowpipe 5, filter bag 6, dust collection drawer 7.

A fan 2 is installed on the cabinet 1 of the utility model, and a dust collection drawer 7 is installed on the bottom of the cabinet 1. A plurality of filter bags 6 are installed in the cabinet 1. Each filter bag 6 is parallel to each other, and the filter bags 6 collect dust vertically. The drawer 7 is set, the dust collection drawer 7 adopts a pull-out structure design, and is set horizontally. The filter bag 6 is located above the drawer 7. There is a composite air blowing pipe 5 above the filter bag 6. There are multiple filter bags 6, which are arranged in parallel. The cabinet body The outer side of 1 is equipped with air storage cylinder 3, and air storage cylinder 3 is connected with compound air blowpipe 5.

A solenoid valve 4 is installed between the compound air blowpipe 5 and the air storage cylinder 3, and the ventilation of the compound air blowpipe 5 is controlled by the solenoid valve 4.

The air storage cylinder 3 can also be connected with an air compressor, and compressed air is stored in the air storage cylinder 3, and it is also possible to adopt the air storage cylinder 3 to store the air driven by the blower fan 2.

When the solenoid valve 4 is opened, air is injected at a speed of about 7kg/cm ² instantaneously, causing the filter bag 6 to expand and vibrate, so that the dust adhering to the surface of the filter bag 6 falls off, that is, the effect of air backwashing the filter bag 6 is achieved. Cleaning filter bag 6 cycle cleaning time interval is about 3 minutes, and the cleaning time is about 0.1 second each time, so it does not affect the filtering effect.

There are multiple compound air blowpipes 5, and there are multiple corresponding solenoid valves 4. The compound air blowpipes 5 are arranged vertically with filter bags 6. There are multiple filter bags 6 below each compound air blowpipe 5. The compound air blowpipes 5 correspond to each The filter bag 6 is provided with an air blowing hole, and when ventilating, the multiple air blowpipe 5 can ventilate to a plurality of filter bags 6 at the same time.

The utility model can also be that: the composite air blowing pipe 5 is connected with a branch pipe corresponding to the filter bag 6, and the branch pipe stretches into the filter bag 6, and the filter bag 6 can be blown by adopting this structure.

The air storage cylinder 3 and the electromagnetic valve 4 are located outside the cabinet body 1 .

The filter bag 6 is a polyester needle-punched felt non-woven filter bag, which can reduce dust sticking to the bag body and make the dust on the bag body easier to clean.

The blowing direction of the composite air blowing pipe 5 of the utility model is opposite to the direction of the normal flow of dust-containing air, so it is called reverse washing filter bag 6. Select the power switch to power on, the power light is on, and directly press the start button, and the dust collector runs reversely. wash program.

Certainly, the embodiment described above is only a preferred example of the utility model, and does not limit the scope of implementation of the utility model, so all equivalent changes made according to the structure, features and principles described in the utility model patent scope Or modification, all should be included in the utility model patent scope.
