Description

Technical Field

[0001] This utility model relates to the field of pulse dust collector technology, and in particular to a cartridge pulse dust collector. Background Technology

[0002] Cartridge pulse dust collectors are a type of high-efficiency dust removal equipment. They use cartridges as the core filtration element. When dust-laden gas enters, coarse particles settle, while fine dust is intercepted by the cartridges. When the dust accumulation in the cartridges reaches a set value, the pulse controller triggers the blow valve, and compressed air is ejected through the blow pipe to remove the dust. They have a high dust removal efficiency of over 99%, small size, large filtration area, stable operation, long cartridge life, convenient installation and maintenance, and can be used continuously.

[0003] When dealing with dust that is highly humid and sticky, such as in food processing and chemical raw material production, the dust easily adheres to the surface of the filter cartridge. As the operating time increases, a thick layer of dust gradually forms, which reduces the air permeability of the filter cartridge and increases the resistance. For example, in a flour processing plant, when the flour dust is slightly humid, it easily adheres to the filter cartridge, causing the air volume handled by the dust collector to decrease and affecting the dust removal effect. Therefore, this utility model proposes a filter cartridge pulse dust collector to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a cartridge-type pulse dust collector to solve the issue in the prior art where dust with high humidity and strong viscosity easily adheres to the filter cartridge, causing a decrease in the air volume processed by the dust collector and affecting the dust removal effect.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a cartridge pulse dust collector, including a housing, a dust collection hopper and an air collection chamber. The dust collection hopper is fixedly connected to the bottom of the housing. An air collection chamber is provided on one side of the housing. A feed pipe is connected to one side of the top of the housing. An air outlet pipe is connected to the bottom of the air collection chamber. The bottom of the air outlet pipe is connected to an external negative pressure fan. A filter cartridge is installed inside the housing through a fixing mechanism. A pulse cleaning mechanism is provided on the other side of the top of the housing.

[0006] A further improvement is that the fixing mechanism includes a fixing frame, a mounting frame, a connecting hole, a threaded pipe, and a ventilation pipe. The fixing frame is fixedly connected to one side of the box body, and multiple mounting frames are fixedly connected at equal intervals to one side of the fixing frame. One side of the mounting frame is inclined downwards, and the inner side of the mounting frame wraps around the filter cartridge. A connecting hole is provided on one side of the filter cartridge, and a threaded pipe is threadedly connected to the inside of the connecting hole. One end of the threaded pipe is fixedly connected to a ventilation pipe.

[0007] A further improvement is that the cross-section of the ventilation pipe along its length is an I-shaped structure, one end of the ventilation pipe is fitted with a sealing ring, and one end of the ventilation pipe is connected to the inside of the connection hole through the sealing ring. The inside of the fixing frame is provided with multiple mounting holes that match the ventilation pipe.

[0008] A further improvement is that a connecting block is fixedly connected to the end of the filter cartridge away from the ventilation pipe, and a slot is provided inside the connecting block. A matching slot is fixedly connected to one side of the mounting frame.

[0009] A further improvement is that the filter cartridge is star-shaped, with the outer side folded into pleats and the ends glued together. The material of the filter cartridge is a high-strength polyester long fiber nonwoven fabric.

[0010] A further improvement is that the pulse cleaning mechanism includes an air tank and pulse valves. An air tank is fixedly installed on one side of the top of the air collection chamber. Multiple pulse valves are installed on the air tank. One end of each pulse valve is connected to a blowpipe. One end of the blowpipe is connected to one end of the ventilation pipe. The interior of the air tank is connected to the output end of the air compressor.

[0011] A further improvement is that an inspection port is provided on one side of the front of the enclosure, and an inspection door is covered on one side of the inspection port. The inspection door is detachably connected to the enclosure by bolts.

[0012] The beneficial effects of this utility model are as follows: the connecting block is engaged with one side of the card block along the inner wall of the card slot, so that the filter cartridge is initially fixed inside the mounting frame. Then, one end of the threaded tube is passed through the mounting hole and connected to one end of the connecting hole. The threaded tube is then screwed into the inside of the connecting hole until the connecting hole and the threaded tube cooperate to clamp the two sides of the fixing frame, so that the filter cartridge is tilted and fixed inside the mounting frame. The filter cartridge has an inclined angle, and the dust that is peeled off during cleaning slides down the surface of the filter cartridge to the dust collection hopper under the action of gravity, reducing the dust residue on the surface of the filter cartridge. This solves the problem in the prior art that when dealing with dust with high humidity and strong stickiness, it is easy to adhere to the filter cartridge, which reduces the processing air volume of the dust collector and affects the dust removal effect.

Detailed Implementation

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a cartridge pulse dust collector, including a housing 1, a dust collection hopper 2, and a gas collection chamber 3. The dust collection hopper 2 is fixedly connected to the bottom of the housing 1. The gas collection chamber 3 is provided on one side of the housing 1. A feed pipe 13 is connected to one side of the top of the housing 1. An exhaust pipe 14 is connected to the bottom of the gas collection chamber 3. The bottom of the exhaust pipe 14 is connected to an external negative pressure fan. A filter cartridge 6 is installed inside the housing 1 through a fixing mechanism. A pulse cleaning mechanism is provided on the other side of the top of the housing 1. The feed pipe 13 is connected to a pipeline for conveying dust-laden gas. The dust-laden gas is drawn into the housing 1 by the negative pressure fan. The filter cartridge 6 inside the housing 1 can separate dust from air. The dust is trapped on the surface of the filter cartridge 6, while air passes through the filter cartridge 6 into the air collection chamber 3. It is then transported to the outside through the air outlet pipe 14 and the negative pressure fan. As dust accumulates on the surface of the filter cartridge 6, the equipment resistance gradually increases. When the resistance reaches the set value, the control system triggers the pulse cleaning mechanism, which generates an instantaneous shock wave and reverse airflow, causing the dust on the surface of the filter cartridge 6 to fall into the dust collection hopper 2 and be discharged to the outside through the dust collection hopper 2. The fixing mechanism can tilt the filter cartridge 6 inside the housing 1. The filter cartridge 6 has an inclined angle, and the dust that is peeled off during cleaning slides down the surface of the filter cartridge 6 to the dust collection hopper 2 under the action of gravity, reducing the amount of dust remaining on the surface of the filter cartridge 6.

[0020] The fixing mechanism includes a fixing frame 4, a mounting frame 5, a connecting hole 7, a threaded pipe 8, and a ventilation pipe 9. The fixing frame 4 is fixedly connected to one side of the inside of the housing 1. Multiple mounting frames 5 are fixedly connected at equal intervals to one side of the fixing frame 4. One side of the mounting frame 5 is inclined downward. The inner side of the mounting frame 5 is wrapped around the filter cartridge 6. A connecting hole 7 is provided on one side of the filter cartridge 6. The threaded pipe 8 is threadedly connected to the inside of the connecting hole 7. One end of the threaded pipe 8 is fixedly connected to the ventilation pipe 9.

[0021] The cross-section of the ventilation pipe 9 along its length is an I-shaped structure. One end of the ventilation pipe 9 is fitted with a sealing ring 10. One end of the ventilation pipe 9 is connected to the inner side of the connection hole 7 through the sealing ring 10. The inside of the fixing frame 4 is provided with multiple mounting holes that match the ventilation pipe 9.

[0022] The filter cartridge 6 is fixedly connected to a connecting block 11 at the end away from the ventilation pipe 9. The connecting block 11 has a slot 12 inside. A card block matching the slot 12 is fixedly connected to one side of the mounting frame 5.

[0023] When installing the filter cartridge 6, firstly, the connecting block 11 is engaged with one side of the card along the inner wall of the slot 12, so that the filter cartridge 6 is initially fixed inside the mounting frame 5. Then, one end of the threaded tube 8 is passed through the mounting hole and connected to one end of the connecting hole 7. Then, the threaded tube 8 is screwed into the inside of the connecting hole 7 until the connecting hole 7 and the threaded tube 8 cooperate to clamp the two sides of the fixing frame 4, so that the filter cartridge 6 is tilted and fixed inside the mounting frame 5. The filter cartridge 6 has an inclined angle, and the dust stripped off during cleaning slides down the surface of the filter cartridge 6 to the dust collection hopper 2 under the action of gravity, reducing the dust residue on the surface of the filter cartridge 6. The sealing ring 10 can fill the gap between the connecting hole 7, the mounting hole and the ventilation pipe 9 to ensure the sealing of the filter cartridge 6.

[0024] The filter cartridge 6 is star-shaped with folds on the outside and the ends glued together. The material of the filter cartridge 6 is high-strength polyester long fiber nonwoven fabric. The application of polyester long fiber filter media gives the filter cartridge 6 not only good acid and alkali resistance, but also higher filtration efficiency and low operating resistance. Compared with traditional filter media, it has incomparable wear resistance, high strength and tear resistance. It is easier to clean with pulse backflushing and other methods, and can be repeatedly washed with water without damaging the filter media, thus extending its service life.

[0025] The pulse cleaning mechanism includes an air tank 15 and pulse valves 16. An air tank 15 is fixedly installed on one side of the top of the air collection chamber 3. Multiple pulse valves 16 are installed on the air tank 15. One end of the pulse valve 16 is connected to a blowpipe 18. One end of the blowpipe 18 is connected to one end of the ventilation pipe 9. The interior of the air tank 15 is connected to the output end of the air compressor. The air compressor sends compressed air into the air tank 15. When dust accumulates on the surface of the filter cartridge 6, causing the resistance to increase, the PLC controls the pulse valve 16 to open, and the high-pressure gas in the air tank is released instantly and sprayed into the filter cartridge 6 at high speed through the blowpipe 18, generating a reverse airflow to remove the dust.

[0026] The front side of the housing 1 is provided with an inspection port, and an inspection door 17 is covered on one side of the inspection port. The inspection door 17 is detachably connected to the housing 1 by bolts. By using a wrench to unscrew the bolts, people can enter the interior of the housing 1 through the inspection port to inspect the parts inside. After completion, the inspection door 17 is covered on one side of the inspection port, and then the bolts are screwed into the interior of the housing 1 to fix the inspection door 17 to one side of the inspection port.

[0027] In this cartridge pulse dust collector, the connecting block 11 is engaged with one side of the slot 12 along the inner wall of the slot, so that the filter cartridge 6 is initially fixed inside the mounting frame 5. Then, one end of the threaded tube 8 is passed through the mounting hole and connected to one end of the connecting hole 7. The threaded tube 8 is then screwed into the connecting hole 7 until the connecting hole 7 and the threaded tube 8 cooperate to clamp the two sides of the fixing frame 4, so that the filter cartridge 6 is tilted and fixed inside the mounting frame 5. The filter cartridge 6 has an inclined angle, and the dust stripped off during cleaning slides down the surface of the filter cartridge 6 to the dust collection hopper 2 under the action of gravity, reducing the dust residue on the surface of the filter cartridge 6. This solves the problem in the prior art that when dealing with dust with high humidity and strong stickiness, it is easy to adhere to the filter cartridge, which reduces the processing air volume of the dust collector and affects the dust removal effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
