Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.

Referring to fig. 1 and 2, a dust removal system for feed processing includes a box 100, where the box 100 is provided with an air inlet 200 and an air outlet 300, and air enters from the air inlet 200 and is discharged from the air outlet 300.

The box body 100 is internally provided with an upper cavity 110, a cylindrical middle cavity 120 and a lower cavity 130, the air inlet 200 is communicated with the middle cavity 120, the air inlet direction of the air inlet 200 is tangent to the middle cavity 120, so that when air enters, cyclone airflow is formed in the middle cavity 120, and the air outlet 300 is communicated with the upper cavity 110.

The middle cavity 120 is internally provided with a flower plate 400 and filter bags 500, the filter bags 500 are distributed on the lower side of the flower plate 400, the upper ends of the filter bags 500 are used as bag openings 510, and the shapes and the working principles of the flower plate 400 and the filter bags 500 can refer to the existing dust collector.

Referring to fig. 2 and 3, a dust cleaning pipe 600 is arranged above the filter bag 500, a blowing pipe 610 is distributed on the dust cleaning pipe 600 and points to a bag mouth 510 of the filter bag 500, and an electromagnetic pulse valve 620 and an air bag 630 are arranged at the inlet end of the dust cleaning pipe 600. The electromagnetic pulse valve 620 is controlled by a pulse controller, the air bag 630 can store air, and the structure and the working principle of the electromagnetic pulse valve 620 and the air bag 630 can refer to the existing pulse dust collector. The cyclone airflow can make the dust of the gas fully contact with the filter bag 500, and the air volume limitation to the inlet air is small, so that the dust can be removed more efficiently.

An ash discharging device 700 is arranged at the lower side of the lower cavity 130, and the ash discharging device 700 is connected with an air blower 710. Embodiments of the ash discharge apparatus 700 may be referred to as existing dusters.

The dust-containing gas tangentially enters the middle cavity 120 from the air inlet 200, the dust with larger particle size is firstly settled to the lower cavity 130 after the rotation separation, the dust-containing gas with smaller particle size is filtered by the filter bag 500 to become purified air, the purified gas enters the upper cavity 110 and is discharged from the air outlet 300, and the dust is accumulated on the outer surface of the filter bag 500. The upper chamber 110 has enough space to prevent the air flow rolled up at the middle chamber 120 from directly blowing out from the outlet 300.

When the dust accumulated in the filter bag 500 of the dust collector reaches a certain amount, the dust is cleaned. When in ash removal, low-pressure pulse airflow is used for sequentially triggering each electromagnetic pulse valve 620 to inject air according to a set requirement by a pulse controller, the air enters the filter bag 500 through the pipe orifice of the injection pipe 610, the filter bag 500 is rapidly expanded instantly, dust accumulated on the surface of the filter bag 500 is shaken off, and the dust enters the dust discharge device 700 and is discharged through the air shutter 710, so that the ash removal is performed through periodic pulse injection, the filter bag 500 is in an effective filtering state, and the normal work of a dust removal system is ensured. The lower chamber 130 is provided with enough space to prevent the gas shaken off by the filter bag 500 from being blown back to the middle chamber 120.

A torsion spring 611 is disposed in the blowing tube 610, and a torsion spring valve 612 is connected to the torsion spring 611, wherein the torsion spring valve 612 can close the nozzle of the blowing tube 610, and when gas is blown out from the nozzle of the blowing tube 610, the torsion spring valve 612 is bounced, so that the gas is injected into the filter bag 500. After the air injection is finished, the torsion spring valve 612 is reset through the torsion spring 611. It should be noted that the torsion spring valve 612 is to reduce the air back-filling and dust-carrying into the blowing tube 610, so that the torsion spring valve 612 is not required to completely seal the blowing tube 610 when it is reset.

The bag mouth 510 is provided with a venturi tube 511, which can improve the supporting degree of the filter bag 500 when gas is injected into the filter bag 500.

The dust discharging device 700 comprises a centrifugal fan 720 and a dust discharging pipeline 730, the dust discharging pipeline 730 is connected with the air seal machine 710, and the centrifugal fan 720 is used for enabling the dust discharging pipeline 730 to form negative pressure, so that dust at the lower cavity 130 enters the dust discharging pipeline 730 to be removed.

A filter screen 800 is arranged between the upper cavity 110 and the middle cavity 120, and the filter screen 800 is positioned above the dust removing pipe 600, so that dust is further reduced from being brought into the upper cavity 110. The filter screen 800 is a nylon screen or an iron wire filter screen.

The upper cavity 110, the middle cavity 120 and the lower cavity 130 are of a detachable structure, and the connecting ring 140 is arranged on the outer sides of the upper cavity 110, the middle cavity 120 and the lower cavity 130. The connection ring 140 between the upper chamber body 110 and the middle chamber body 120, and the connection ring 140 between the middle chamber body 120 and the lower chamber body 130 can be connected by bolts or other means after being aligned. The detachable structure facilitates the replacement of the card 400 and the filter bag 500.
