Description

Technical Field

[0001] The present invention relates to the technical field of dust collectors, and specifically relates to a pulse dust collector for feed production. Background Art

[0002] A pulse dust collector is a common gas-solid separation device, usually composed of components such as filter bags, pulse valves, spray pipes, boxes, and ash hoppers. It is mainly used to treat dust-containing gases and is widely used in industries with large dust generation such as feed production; In the prior art, when the pulse dust collector is working, first, the dust-containing gas is inhaled into the dust collector box through the air inlet. When the dust-containing gas passes through the filter bag, the dust is intercepted on the outer surface of the filter bag, and the purified gas is discharged through the inside of the filter bag. When the dust accumulated on the surface of the filter bag reaches a certain thickness, the control system triggers the pulse valve, and high-pressure gas is instantly ejected from the spray pipe, forming a high-speed air flow through the Venturi effect, impacting the filter bag to make the dust fall and fall into the ash hopper, thereby ensuring the filtration efficiency of the filter bag; However, under the spray of high-pressure pulses, the filter bag is prone to aging and damage and needs to be frequently replaced. In the prior art, when replacing the filter bag, the box needs to be opened, and the filter bag needs to be disassembled and installed in the narrow space of the box, which is relatively inconvenient to operate and has low efficiency. At the same time, in the prior art, when blowing the filter bag, the high-pressure gas enters the inside of the filter bag vertically, and the gas entering the inside of the filter bag is parallel to the side wall of the filter bag. When the high-pressure gas expands in the filter bag, it has an effect of cleaning the filter bag, and when the high-pressure gas expands, part of the gas expands upward, resulting in a reduction in the efficiency of the pulse spray.

A filter bag support 3 is arranged inside the U-shaped groove 22. The filter bag support 3 is installed inside the drawable support 2 through the U-shaped groove 22. The filter bag support 3 has an inverted conical structure. A filter bag 31 is sleeved on the surface of the filter bag support 3; The translation frame 8 is arranged on the side surface of the limiting ring 6. A sliding groove 81 is formed on the surface of the translation frame 8. The sliding rod 61 is slidably arranged inside the sliding groove 81. The translation frame 8 is arranged above the partition plate 5. One side of the translation frame 8 close to the front baffle 23 is fixedly connected with a pressure-receiving rod 83. One end of the pressure-receiving rod 83 away from the translation frame 8 extends to the outside of the dust collector box body 1, and a second guiding slope 84 is arranged at the end of the pressure-receiving rod 83 extending to the outside of the dust collector box body 1.

The guiding rod 82 slidably penetrates through the guiding hole 53. A compression spring is arranged between the translation frame 8 and the limiting plate 52.

[0024] For a pulse dust collector used in feed production proposed by the present invention, during use, the dusty gas is introduced into the inside of the draw bracket 2 and the dust collector box body 1 through the air inlet 121. The heavier dust in the dusty gas falls into the inside of the ash hopper 12 under the action of gravity. When the dusty gas passes through the filter bag 31, the dust is filtered by the filter bag 31. The filtered gas enters the inside of the dust collector upper cover 13 through the limiting ring 6 and is finally discharged through the air outlet 131. When the dust on the surface of the filter bag 31 is relatively thick, the air compressor blows high-pressure gas into the inside of the filter bag 31 through the blowing nozzle 92 to impact the filter bag 31 so that the dust drops into the inside of the ash hopper 12. When the filter bag 31 needs to be replaced during use, the threaded rod 722 is rotated by driving the grip rod 72, so that the threaded rod 722 disengages from the inside of the threaded sleeve 15. Then, the gear 71 is rotated by driving the grip rod 72 and the control handle 7, so that the gear 71 pulls down the first ejector rod 4 through the toothed plate 441, and the pressing plate 42 disengages from the inside of the limiting frame 45. The translation frame 8 moves towards the direction close to the front baffle 23 under the action of the compression spring. During the movement of the translation frame 8, the limiting ring 6 is driven to move upward through the sliding groove 81 and the sliding rod 61, so that the sealing ring 62 is separated from the filter bag support 3, and at the same time, the side stop block 63 disengages from the inside of the U-shaped groove 22. At this time, by pulling the draw bracket 2 through the control handle 7, the draw bracket 2 can be pulled out from the inside of the dust collector box body 1, so as to realize the replacement of the filter bag 31 outside the dust collector box body 1, improving the operation convenience and the efficiency of replacing the filter bag 31.

[0025] As a further improvement of the present invention, by providing a liftable limit ring 6, after the filter bag 31 is replaced, rotate the control handle 7 to align the threaded rod 722 with the threaded sleeve 15, and tighten the threaded rod 722 inside the threaded sleeve 15. At this time, the pressing plate 42 rises and inserts into the inside of the limit frame 45, forming a squeeze on the pressure rod 83, causing the translation frame 8 to translate in the direction close to the limit plate 52. The translation frame 8 presses down the limit ring 6 through the sliding groove 81 and the sliding rod 61, so that the sealing ring 62 is pressed tightly above the filter bag support 3. At the same time, the side stop block 63 is inserted into the U-shaped groove 22, and the filter bag support 3 is limited inside the U-shaped groove 22, realizing the locking of the filter bag support 3 while locking the pull-out support 2, greatly improving the efficiency of replacing the filter bag 31.

[0026] As a further improvement of the present invention, by setting the filter bag support 3 to an inverted cone shape, and at the same time making the axes of multiple groups of spray nozzles 92 installed on the surface of the spray head 91 intersect with the axis of the spray pipe 9, the pulsed gas collides with the side wall of the filter bag 31 obliquely when entering the inside of the filter bag 31, so that the pulsed gas forms an impact on the side wall of the filter bag 31 before expansion, and the pulsed gas impacts the side wall of the filter bag 31 again when expanding, thus realizing two impacts in one pulse, greatly improving the efficiency of pulsed spraying.
