Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling, and in particular to an industrial pulse dust collector. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive and negative electrode materials and a non-aqueous electrolyte solution. A traditional lithium-ion battery consists of five main parts: positive electrode material, negative electrode material, electrolyte, diaphragm, and casing. Because lithium-ion batteries contain many harmful substances that can pollute the environment, they need to be recycled after degradation. Dust and exhaust gases generated during dismantling require cleaning treatment using industrial dust collectors before being discharged. Industrial dust collectors are devices used in industrial applications to collect and absorb particulate matter, dust, fumes, oil, and water generated during production, operation, and transportation. As a major daily cleaning tool in modern industry, they have a frequent interaction with users.

[0003] Existing industrial pulse vacuum cleaners can automatically clean the dust on the outer surface of the filter element by back-blowing. However, relying solely on air back-blowing is not effective at cleaning some sticky impurities and moist dust. Furthermore, traditional industrial vacuum cleaners have incomplete air-solid separation, low structural strength, poor stability, and troublesome dust recovery. The use and replacement of filter bags are inconvenient, and the lifespan of the filter bags is also shortened, requiring frequent replacement. Utility Model Content

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] In the attached diagram, all identical reference numerals refer to the same components.

[0024] like Figure 1-4 As shown, this utility model provides an industrial pulse dust collector, including a housing 1;

[0025] The top of the housing 1 is equipped with several clean air chambers 2. An air storage tank 8 is fixed to one side of each clean air chamber 2. A first through hole, through which an air supply pipe 21 can pass, is opened on the side of each clean air chamber 2, located on the side of the air storage tank 8. Several filter cartridge devices 3 are arranged in a matrix at the bottom of each clean air chamber 2. Several second through holes are opened on the bottom plate of each clean air chamber 2 corresponding to the filter cartridge devices 3. An air nozzle 5 is installed above each filter cartridge device 3. One end of each air nozzle 5 extends into the interior of the filter cartridge device 3, and the other end extends above the bottom plate of the clean air chamber 2. Several evenly distributed air inlet ports 6 are provided above the air nozzle 5 on the air supply pipe 21. The air inlet ports 6 are connected to the air outlet of the air storage tank 8 through the air supply pipe 21. A dust inlet hopper 7 is fixedly installed on one side wall of the clean air chamber 2 and is connected to the clean air chamber 2. An air induced device 4 is connected to the side wall of the dust inlet hopper 7 away from the clean air chamber 2. A dust collection hopper 10 is fixedly connected to the bottom of the box 1. An air outlet 9 is connected to the bottom of the dust collection hopper 10 symmetrical to the side wall of the dust inlet hopper 7. An anti-clogging component 11 is connected to the bottom of the dust collection hopper 10.

[0026] In this embodiment, there are three clean air chambers 2, each with two parallel air supply pipes 21. Multiple air inlet ports 6 are connected to the bottom of each air supply pipe 21. Compressed gas is injected into the air nozzles 5 below through the air inlet ports 6, causing the filter bag 32 to expand. An air pipe connected to an external air compressor is located on the side of the air storage tank 8, allowing for a continuous supply of compressed air. A pressure valve is also installed on the side wall of the clean air chamber 2 to monitor the gas pressure inside. When the equipment pressure rises to a set value, the control box 45 activates the pulse valve 24 to perform dust removal.

[0027] The method of using this utility model is as follows:

[0028] 1. Dust-laden gas enters the clean air chamber 2 through the dust inlet hopper 7. After being blocked by the side wall of the clean air chamber 2, the airflow is redirected and flows into the filter cartridge device 3. At the same time, the airflow speed slows down. Due to inertia, coarse dust particles in the gas flow directly into the filter bag 32. The purified gas enters the dust collection hopper 10 at the bottom of the filter bag chamber and is collected at the outlet 9 for discharge.

[0029] 2. As the filtration time increases, the dust layer on the filter bag 32 continues to thicken, and the pressure of the dust removal equipment continues to rise. When the equipment pressure rises to the set value, the air volume regulating valve 44 is closed to cut off the airflow. Then the pulse valve 24 is opened to start the dust removal process. Compressed air is ejected from the air inlet port 6 and expands rapidly in the clean air chamber 2 in a very short time. It rushes into the filter bag 32, causing the filter bag 32 to expand and deform and vibrate. Under the action of the compressed air flow, the dust attached to the outer surface of the filter bag 32 is peeled off and falls into the dust collection hopper 10.

[0030] 3. After the dust removal is completed, the pulse valve 24 closes, and the clean air chamber 2 returns to the filtration state. The dust trapped after filtration and dust removal falls into the bottom of the dust collection hopper 10, and is then discharged by the anti-clogging component 11 below the dust collection hopper 10.

[0031] Furthermore, the clean air chamber 2 includes a cover plate 22, which is disposed on the top of the clean air chamber 2. The cover plate 22 is detachably connected to the upper surface of the clean air chamber 2. Locking handles 23 are fixed around the four corners of the cover plate 22 on the top of the clean air chamber 2. If the clean air chambers 2 are evenly distributed above the housing 1, the side walls of adjacent clean air chambers 2 are interconnected. The gas containing dust stays in the clean air chamber 2. Some of the large dust particles in the gas are separated by inertial force and gravity and fall into the bottom of the filter bag 32. Small dust particles are adsorbed on the surface of the filter bag 32.

[0032] In this embodiment, the cover plate 22 is provided with a lifting handle. When the filter bag 32 collects a large amount of dust, it is necessary to replace the dirty bag. The locking handle 23 can be loosened, the cover plate 22 can be opened to take out the internal filter cartridge frame 31, and the filter bag 32 can be removed. A safety guardrail is also provided on the outer perimeter of the clean air chamber 2.

[0033] Furthermore, the filter cartridge device 3 includes a filter cartridge frame 31 and a filter bag 32. Several third through holes are provided on the bottom plate of the clean air chamber 2. The filter cartridge frame 31 is cylindrical in shape and is placed in the third through holes on the bottom plate of the clean air chamber 2. The filter bag 32 is fitted inside the filter cartridge frame 31. The filter cartridge frame 31 is coaxially arranged with the large end of the air nozzle 5.

[0034] In this embodiment, the filter cartridge frame 31 is detachably connected to the clean air chamber 2 and is fixed to the bottom plate of the clean air chamber 2 by its own weight, so as to facilitate the removal of the filter cartridge frame 31.

[0035] Furthermore, the exhaust fan 4 includes a cyclone fan 41, an exhaust pipe 42, and an intake pipe 43. The inlet end of the cyclone fan 41 is connected to the intake pipe 43, and the outlet end of the cyclone fan 41 is connected to the exhaust pipe 42. An air volume regulating valve 44 is also provided on the exhaust pipe 42. The bottom of the exhaust pipe 42 is fixed to the ground by a fixed bracket. The upper end of the exhaust pipe 42 is connected to the side of the ash hopper 7. A control box 45 is fixed to the side of the cyclone fan 41, and the control box 45 is electrically connected to the cyclone fan 41.

[0036] In this embodiment, the control box 45 controls the rotation of the cyclone separator 41, the air inlet pipe 43 is connected to the dust discharge outlet of the previous process, and the air volume regulating valve 44 can control the air volume entering the ash hopper 7. During the filtration process, when the air pressure in the clean air chamber 2 rises to a certain value, the air volume entering the ash hopper 7 can be reduced by the air volume regulating valve 44. When pulse dust removal is required, the cyclone separator 41 is stopped from rotating by the control box 45, and the air volume regulating valve 44 is closed to cut off the airflow entering the clean air chamber 2 for dust removal.

[0037] Furthermore, the cross-section of the ash collection hopper 10 is V-shaped, and an ash discharge groove is provided at the center of the bottom of the ash collection hopper 10. The anti-clogging component 11 is fixed to the bottom of the ash collection hopper 10 and communicates with the ash discharge groove. The anti-clogging component 11 includes a vane valve 51. The main shaft of the vane valve 51 is connected to an external motor. An opening is provided below the vane valve 51, and a dust collection bag is connected to the outside of the opening.

[0038] In this embodiment, the external motor is electrically connected to the control box 45. When the dust in the dust collection hopper 10 accumulates to a certain amount, the vane valve 51 can be opened through the control box 45 to discharge the accumulated dust in the dust collection hopper 10.

[0039] Furthermore, a pulse valve 24 is provided between the gas supply pipe 21 and the gas storage tank 8. The inlet end of the pulse valve 24 is connected to the gas storage tank 8, and the outlet end of the pulse valve 24 is connected to the gas supply pipe 21. The pulse valves 24 are evenly distributed along the gas storage tank 8, and each gas supply pipe 21 corresponds to one pulse valve 24.

[0040] In this embodiment, the pulse valve 24 is controlled by a solenoid valve. All solenoid valves are connected to the control box 45. The solenoid valves are controlled by the program set in the control box to realize the timed release of compressed air from the gas storage tank 8 into the gas delivery pipe 21, thereby achieving the effect of pulse cleaning.

[0041] Furthermore, four support legs 61 are installed in a matrix at the bottom of the housing 1 and on the outside of the ash collection hopper 10, and a viewing window 62 is opened on one side surface of the ash collection hopper 10.

[0042] In this embodiment, the dirty bag after collecting a certain amount of dust is removed from the filter cartridge frame 31, then put into the dust collection hopper 10 at the bottom of the box 1, and then taken out through the viewing window 62, which improves the bag replacement operation conditions of the filter bag 32.

[0043] This utility model is an industrial pulse dust collector. By setting up a separate clean air chamber 2 for pulse jet cleaning, a thorough cleaning can be achieved with a single pulse jet, thus extending the cleaning cycle and reducing cleaning energy consumption. In addition, it adopts a top-loading bag removal method. When changing bags, after pulling out the filter cartridge frame 31, the dirty bag is put into the dust collection hopper at the bottom of the housing and removed through the viewing window, improving the bag changing operation conditions.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
