Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulse dust filter technology, specifically a pulse dust filter for pig feed processing. Background Technology
[0002] In the pig feed processing industry, a large amount of dust is generated in a series of production processes, from raw material crushing and mixing to pelleting. This dust not only permeates the air in the production workshop, but also poses a serious threat to the respiratory health of operators. Long-term inhalation of dust can easily lead to occupational diseases such as pneumoconiosis, endangering the health of workers. Furthermore, dust accumulation on the surface of production equipment can affect the normal operating accuracy and service life of the equipment, increasing maintenance costs. At the same time, excessive dust may also form explosive mixtures, which, when they reach a certain concentration and encounter a source of ignition, can cause dust explosions, bringing huge safety hazards and economic losses to enterprises.
[0003] Therefore, pulse jet filters have become a key environmental protection device for controlling dust pollution during pig feed processing. Pulse jet filters filter dust-laden air through filter cartridges and then periodically clean the dust adhering to the surface of the filter cartridges using pulse jets to ensure stable dust filtration efficiency. They are widely used in dust control within pig feed processing production lines.
[0004] Existing pulse dust filters used for pig feed processing still have obvious technical defects in actual use: for example, the connection between the filter cartridge and the equipment box of existing pulse dust filters is mostly fixed by bolts or flanges, which makes it very inconvenient to replace the filter cartridge.
[0005] Therefore, we propose a pulse dust filter for pig feed processing. Utility Model Content
[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a pulse dust filter for pig feed processing, which solves the problem that existing pulse dust filters often use bolts or flanges to fix the filter cartridge to the equipment housing, making filter cartridge replacement very inconvenient.
[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a pulse dust filter for pig feed processing, comprising a housing, a filter cartridge, and a pulse assembly. A support plate is fixedly connected inside the housing, and the support plate has several evenly distributed through holes. The upper end of the filter cartridge is inserted into the through holes, and the pulse assembly is disposed above the support plate. A sleeve is fixedly connected to the outer wall of the upper end of the filter cartridge. A slot is provided on the inner wall of the sleeve. A connecting pipe is provided at the bottom of each through hole of the support plate. The sleeve is sleeved on the lower end of the connecting pipe. A cavity is provided on both sides of the connecting pipe. A spring is provided in the cavity. One end of the spring abuts against a movable plate. A locking block and a pressing block are fixedly connected to one side of the movable plate.
[0008] Preferably, an air inlet pipe and an exhaust pipe are provided on one side of the housing, with the air inlet pipe located below the support plate and the exhaust pipe located above the support plate.
[0009] Preferably, a door is hinged to one side of the box.
[0010] Preferably, support columns are fixedly installed at the four corners of the bottom of the box.
[0011] Preferably, the pulse assembly includes an air tank fixedly installed on the outside of the housing, with a plurality of evenly distributed air guide pipes fixedly connected to the top of the air tank, the air guide pipes extending into the housing and equipped with nozzles, and a pulse solenoid valve installed at one end of the air guide pipes.
[0012] Preferably, the bottom of the box is provided with a dust discharge port.
[0013] Preferably, the side of the card block away from the movable plate is provided with an inclined surface.
[0014] Preferably, a limiting rod is fixedly connected inside the cavity, and both the spring and the movable plate are movably sleeved on the limiting rod.
[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a pulse dust filter for pig feed processing, which has the following beneficial effects: 1. This utility model, by setting up a sleeve, a slot, a connecting pipe, a spring, a movable plate, a locking block, and a pressing block, allows for easy installation of the filter cartridge. Simply align the upper end of the filter cartridge with the through hole and insert it. Then, the sleeve will simultaneously fit over the lower end of the connecting pipe. At this time, the spring will push the movable plate to move, causing the movable plate to drive the locking block into the slot, thus fixing the filter cartridge. When disassembling the filter cartridge, simply press the pressing block to move the movable plate, causing the movable plate to move the locking block out of the slot, allowing the filter cartridge to be pulled out downwards. This facilitates the replacement of the filter cartridge.
[0016] 2. This utility model has an inclined surface on one side of the locking block. When the sleeve plate contacts the inclined surface of the locking block during filter cartridge installation, it will push the locking block into the cavity, making it easier to put the sleeve plate on the lower end of the connecting pipe and making the operation more convenient.

[0020] This utility model provides a technical solution: Please see Figures 1-3 A pulse dust filter for pig feed processing includes a housing 1, a filter cartridge 2, and a pulse assembly 3. A support plate 11 is fixedly connected inside the housing 1. The support plate 11 has several evenly distributed through holes 12. The upper end of the filter cartridge 2 is inserted into the through holes 12. An air inlet pipe 18 and an exhaust pipe 19 are provided on one side of the housing 1. The air inlet pipe 18 is located below the support plate 11, and the exhaust pipe 19 is located above the support plate 11. When processing dust in the pig feed processing process, air enters the housing 1 through the air inlet pipe 18. After the filter cartridge 2 filters the dust in the air, the filtered air is discharged through the exhaust pipe 19.
[0021] The pulse assembly 3 is positioned above the support plate 11. The pulse assembly 3 includes an air bag 31 fixedly installed on the outside of the housing 1. Multiple evenly distributed air guide pipes 32 are fixedly connected to the top of the air bag 31. The air guide pipes 32 extend into the housing 1 and are equipped with nozzles 33. A pulse solenoid valve 34 is installed at one end of the air guide pipe 32. When it is necessary to clean the dust attached to the filter cartridge 2, the pulse solenoid valve 34 can be opened to make the nozzles 33 pulse jet towards the filter cartridge 2, thereby blowing away the dust attached to the filter cartridge 2.
[0022] The box body 1 has a hinged door 110 on one side, and support columns 111 are fixedly installed at the four corners of the bottom of the box body 1. The bottom of the box body 1 is provided with a dust discharge port 112, which has a baffle valve (not shown in the figure). The blown dust can be discharged from the dust discharge port 112.
[0023] Specifically, a sleeve 21 is fixedly connected to the outer wall of the upper end of the filter cartridge 2. A slot 22 is provided on the inner wall of the sleeve 21. A connecting pipe 13 is provided at the bottom of each through hole 12 on the support plate 11. The sleeve 21 is sleeved on the lower end of the connecting pipe 13. A cavity is provided on both sides of the connecting pipe 13. A spring 14 is provided in the cavity. One end of the spring 14 abuts against a movable plate 15. A locking block 16 and a pressing block 17 are fixedly connected to one side of the movable plate 15. An inclined surface is provided on the side of the locking block 16 away from the movable plate 15. A limit rod 113 is fixedly connected in the cavity. The spring 14 and the movable plate 15 are movably sleeved on the limit rod 113. The system includes a sleeve 21, a slot 22, a connecting pipe 13, a spring 14, a movable plate 15, a locking block 16, and a pressing block 17. When installing the filter cartridge 2, simply align the upper end of the filter cartridge 2 with the through hole 12 and insert it. Simultaneously, the sleeve 21 will be placed over the lower end of the connecting pipe 13. At this time, the spring 14 will push the movable plate 15 to move, causing the movable plate 15 to move and the locking block 16 to insert into the slot 22, thus fixing the filter cartridge 2. When disassembling the filter cartridge 2, simply press the pressing block 17, causing the pressing block 17 to move and the movable plate 15 to move, causing the movable plate 15 to move the locking block 16 out of the slot 22, allowing the filter cartridge 2 to be pulled out downwards, facilitating the replacement of the filter cartridge 2.
[0024] In practical use, the working principle of this utility model is as follows: First, when installing the filter cartridge 2, simply align the upper end of the filter cartridge 2 with the through hole 12 and insert it. Then, the sleeve 21 will simultaneously be placed on the lower end of the connecting pipe 13. At this time, the spring 14 will push the movable plate 15 to move, so that the movable plate 15 will drive the locking block 16 to be inserted into the locking groove 22, thereby fixing the filter cartridge 2.
[0025] Next, when dealing with dust during the pig feed processing, air enters the housing 1 through the air inlet pipe 18, the filter cartridge 2 filters the dust in the air, and the filtered air is discharged through the exhaust pipe 19.
[0026] When it is necessary to clean the dust attached to the filter cartridge 2, the pulse solenoid valve 34 can be opened to make the nozzle 33 spray pulse jets towards the filter cartridge 2, thereby blowing off the dust attached to the filter cartridge 2. The blown-off dust can be discharged from the ash discharge port 112.
[0027] When disassembling filter cartridge 2, open the box door 110, and then simply press the pressing block 17 to move the movable plate 15, so that the movable plate 15 moves the locking block 16 out of the locking groove 22, and the filter cartridge 2 can be pulled out downwards, which facilitates the replacement of filter cartridge 2.
[0028] In summary, the pulse dust filter for pig feed processing facilitates the replacement of the filter cartridge 2 by setting up a sleeve plate 21, a slot 22, a connecting pipe 13, a spring 14, a movable plate 15, a locking block 16, and a pressing block 17.
[0029] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
