Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in feed production, and in particular to a dust removal device for feed production. Background Technology

[0002] Bag pulse dust collectors are commonly used in feed production. They are devices used to remove particulate matter from the air in industrial environments. They use cloth bags as the filter medium and remove dust from the bag surface through pulse jet cleaning, thereby maintaining equipment operating efficiency and environmental cleanliness.

[0003] A search revealed Chinese Patent Publication No. CN220026360U, which discloses a pulse dust collector for feed production. The collector includes a housing with a base fixedly installed at the lower end. A dust hopper is fixed at the bottom of the housing, and an air inlet is located on the left side of the dust hopper. A door is hinged and mounted on the outside of the housing, and an air outlet is located on the right side of the upper end of the housing. This invention's heating device reduces bag clogging caused by moisture. Multiple heating tubes improve heating efficiency, and a baffle plate prevents dust from falling onto the heating tubes during dust removal, thus reducing heating efficiency.

[0004] While the aforementioned technologies can reduce bag clogging, disassembling the filter bag requires first disconnecting the upper connecting pipe, then sliding out the support, and finally sliding out the internal filter bag for replacement. This method leads to dust contamination of the upper device and is complex and inconvenient to use. Therefore, a dust removal device for feed production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dust removal device for feed production, which aims to improve the problem of the relatively complicated replacement of filter bags.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal device for feed production, comprising a shell, a dust hopper fixedly connected to the lower end of the shell, an air outlet assembly fixedly connected to the lower end of the shell, a support fixedly connected to the lower end of the air outlet assembly, a fixed plate contacting the lower part of the upper end of the support, a locking block elastically connected inside the fixed plate by a spring, a sliding block fixedly connected to the side end of the locking block, an inclined block contacting the lower end of the locking block, a fixing ring fixedly connected to the lower part of the inclined block, a release assembly contacting the lower part of the fixing ring, a sliding ring slidably connected to the outside of the locking block, and a cloth bag slidably connected to the middle of the sliding ring.

[0007] As a further description of the above technical solution:

[0008] The positioning component includes a positioning ring, with fixing blocks fixedly connected to the left and right ends of the positioning ring. The lower end of the fixing block is elastically connected to the middle interior of the outer shell by a spring.

[0009] As a further description of the above technical solution:

[0010] The air outlet assembly includes a connecting pipe, with an air inlet fixedly connected to the lower part of the connecting pipe. The lower part of the air inlet is fixedly connected to the top of the bracket, and both ends of the connecting pipe are fixedly connected to the upper interior of the outer casing.

[0011] As a further description of the above technical solution:

[0012] The lower part of the bracket is slidably connected to the inside of the cloth bag, and the outer side of the fixing plate is fixedly connected to the upper inside of the outer shell.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the side end of the locking block, and the other end of the spring is fixedly connected to the inside of the fixing plate. The outside of the sliding block is slidably connected to the inside of the fixing plate.

[0015] As a further description of the above technical solution:

[0016] The upper part of the inclined block is slidably connected to the lower end of the fixed plate, and the outer part of the sliding ring is slidably connected to the inside of the fixed plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the inclined block can be squeezed to make the card block slide out of the sliding ring. Then, the sliding ring can drive the cloth bag to slide out at the same time for replacement. There is no need to climb to the top of the equipment, and the upper part of the fixed plate will not be contaminated. In addition, the bracket and connecting pipe do not need to be repeatedly disassembled and installed, which increases the convenience of operation.

[0023] 2. In this utility model, by sliding the positioning ring upwards, multiple sets of fixing rings can slide upwards to release the locking block from its limit, which increases the ease of operation. In use, it can support the fixing rings so that they can only slide vertically relative to each other within a fixed distance to maintain their fixed position. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a dust removal device for feed production, comprising a housing 1. The housing 1 supports and maintains the overall device in a relatively fixed position. An air outlet is fixed to the upper side of the housing 1 to discharge clean air, and a sliding door is opened on the side to allow for the replacement and maintenance of the filter bags 7. A dust hopper 2 is fixedly connected to the lower end of the housing 1. The dust hopper 2 is conical, allowing dust that has not entered the filter bags 7 to fall and be discharged through the dust hopper 2. An inlet is opened on the side of the dust hopper 2 to connect to a dust collection device, allowing outside air to enter the housing 1. Inside, an air outlet assembly is fixedly connected to the upper end of the outer casing 1. The air outlet assembly includes a connecting pipe 3. The left end of the connecting pipe 3 can be fixed to the air bag, and the right end can discharge the filtered air through the air outlet. An air inlet 4 is fixedly connected to the lower part of the connecting pipe 3. The air inlet 4 can send the air inside the cloth bag 7 into the connecting pipe 3. The lower part of the air inlet 4 is fixedly connected to the top of the bracket 8. The bracket 8 can connect the cloth bag 7 and the air inlet 4. Both ends of the connecting pipe 3 are fixedly connected to the upper end of the outer casing 1. The outer casing 1 can support and keep the connecting pipe 3 in a horizontal and fixed state.

[0034] Reference Figures 4-6 The lower end of the air outlet assembly is fixedly connected to a bracket 8. The lower part of the bracket 8 is slidably connected to the inside of the cloth bag 7. The bracket 8 can support and keep the cloth bag 7 in a cylindrical shape and keep it fixed. The lower end of the bracket 8 contacts a fixing plate 5. The fixing plate 5 can support and keep the cloth bag 7 fixed relative to the outer shell 1. The outer side of the fixing plate 5 is fixedly connected to the upper end of the outer shell 1. The inside of the fixing plate 5 is elastically connected to a locking block 15 through a spring 14. The locking block 15 has a square groove in the middle so that the inclined block 16 can slide in. The locking block 15 can keep the sliding ring 9 fixed relative to the fixing plate 5, which is convenient for installation. One end of the spring 14 is fixedly connected to the side end of the locking block 15, and the other end of the spring 14 is fixedly connected to the inside of the fixing plate 5. The spring 14 can press the locking block 15 to fix it inside the side end of the sliding ring 9. The side end of the locking block 15 is fixedly connected to a sliding block 6. The outside of the sliding block 6 is slidably connected to the inside of the fixing plate 5. The sliding block 6 can prevent the locking block 15 from sliding horizontally within a fixed distance.

[0035] Reference Figures 3-5The lower end of the locking block 15 contacts the inclined block 16. The upper end of the inclined block 16 is inclined, which can squeeze the square groove to make the locking block 15 slide out of the sliding ring 9. This allows the sliding ring 9 to slide out to replace and clean the cloth bag 7 without contaminating the upper part of the fixing plate 5. Replacement is quick and convenient. The upper part of the inclined block 16 is slidably connected to the lower end of the fixing plate 5. The fixed plate 5 can now only slide the inclined block 16 vertically. The lower part of the inclined block 16 is fixedly connected to the fixing ring 12, which can drive the inclined block 16 to slide vertically. The lower part of the fixing ring 12 contacts the release component. The outer side of the locking block 15 is slidably connected to the sliding ring 9, which can support the cloth bag 7 and fix it relative to the fixing plate 5. The outer side of the sliding ring 9 is slidably connected to the inside of the fixing plate 5. The fixed plate 5 can now only slide the sliding ring 9 vertically. The middle of the sliding ring 9 is slidably connected to the cloth bag 7, which can filter the air below, preventing dust from entering the cloth bag 7 and achieving the dust removal effect.

[0036] Reference Figures 2-4 The positioning component includes a positioning ring 13, which is composed of multiple sets of fixed circles. It can drive multiple sets of fixed rings 12 to slide upwards simultaneously, making it easy to release the limit and disassemble the cloth bag 7. The upper part of the positioning ring 13 is in contact with the lower part of the fixed ring 12. The positioning ring 13 can support and keep the fixed ring 12 from sliding vertically within a fixed distance, so that the inclined block 16 will not slide completely out of the lower end of the fixed plate 5. Fixed blocks 10 are fixedly connected to the left and right ends of the positioning ring 13. The fixed blocks 10 can support and keep the positioning ring 13 horizontal. The lower end of the fixed block 10 is elastically connected to the middle of the outer shell 1 through a second spring 11. The second spring 11 pulls the fixed block 10 so that it can drive the positioning ring 13 to maintain a stable state. One end of the second spring 11 is fixedly connected to the inside of the outer shell 1. The second spring 11 is held in the state of pulling the fixed block 10 by the pulling force of the outer shell 1. The other end of the second spring 11 is fixedly connected to the lower part of the fixed block 10.

[0037] Working principle: External air is delivered into the dust hopper 2 through the inlet of the dust collection device, and then filtered by the cloth bag 7. The filtered air enters the connecting pipe 3 through the air inlet 4 and is discharged through the air outlet. Dust can also be discharged through the dust hopper 2. When the cloth bag 7 needs to be replaced, the sliding door on the side of the outer shell 1 can be opened, and then the fixing ring 12 or the positioning ring 13 can be slid up. The positioning ring 13 drives the fixing block 10 and the fixing ring 12 to slide up simultaneously. The fixing block 10 pulls the second spring 11. At this time, the fixing ring 12 drives the inclined block 16 to slide up. The inclined block 16 slides up and presses the square groove, causing the locking block 15 to slide out of the sliding ring 9 and press the first spring 14. At this time, the sliding ring 9 drives the cloth bag 7 to slide down out of the height range of the bracket 8, and the cloth bag 7 can be taken out for cleaning. Replace the original position by releasing the positioning ring 13, which causes the positioning ring 13, the fixing ring 12, and the inclined block 16 to slide back to their original positions. The locking block 15 slides out under the pressure of the spring 14 until the sliding block 6 is restricted by the fixing plate 5 and stops sliding. Then, the cloth bag 7 is clipped into the upper end of the sliding ring 9. The fixing ring 12 is slid up, which causes the inclined block 16 to press the locking block 15 again. Then, the sliding ring 9 is slid up to its original position. At this time, the bracket 8 slides into the cloth bag 7 for support and fixation. Then, the fixing ring 12 or the positioning ring 13 is released, which causes the spring 11 to pull the positioning ring 13 and the fixing block 10 back to their original positions and keep them fixed. The fixing ring 12 and the inclined block 16 slide back to their original positions, and the spring 14 presses the locking block 15 into the side end of the sliding ring 9 and keeps it fixed.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
