Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a centralized dust removal device used in a lithium battery cell production workshop. Background Art

[0002] Due to the non-renewable nature of fossil energy, lithium-ion batteries have emerged in the energy field of the 21st century. The rapid development of this field is due to the high energy density, long cycle life and low self-discharge of lithium-ion batteries.

[0003] During the production of lithium-ion batteries, it is particularly important to pay attention to the impact of dust in the production workshop on lithium-ion battery production. The raised dust, smoke and welding slag not only pollute the working environment, but also affect the safety and stability of the battery, and also increase the risk of fire and dust explosion. Therefore, in order to avoid this situation, industrial dust collectors are usually used to deal with the dust. When in use, the dust is first sucked into the filter chamber by the vacuum cleaner, and then the dust is intercepted by the filter element in the filter chamber, thereby achieving dust treatment;

[0004] When the common industrial dust collector in the prior art processes dust, a large amount of dust will adhere to the outside of the filter element because the high-speed wind speed will carry the dust directly into contact with the filter element after the dust enters the filter chamber, causing the filter holes of the filter element to be blocked. In order to ensure the normal use of the dust collector, the filter element needs to be cleaned frequently, but frequent cleaning of the filter element will affect work efficiency.

[0019] (3) The utility model moves toward the inside of the filter box through the connection frame driven by the baffle. During this process, the slider squeezes the spring. When a dust cleaning operation is completed, no more gas enters the air inlet. At this time, the baffle rotates downward and resets under the action of its own gravity. At this time, the connection frame is no longer squeezed by the baffle, so it moves to the side of the air inlet and resets under the action of the spring's own elastic restoring force, which is convenient for subsequent use.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] A centralized dust removal device for lithium battery cell production workshop in the embodiment of the present utility model, please refer to the attached figure Figure 1-Figure 5 As shown, it includes a one-way explosion-proof valve 1, a dust removal device body 2, a filter 3 and a cooler 4;

[0029] The dust removal device body 2 includes a filter box 12, a top side of the filter box 12 is provided with an air outlet, an air outlet grille 5 is connected to the air outlet, a filter cartridge 51 is fixedly connected inside the filter box 12 and located below the air outlet, a filter element is provided in the filter cartridge 51, a dust collection box 9 is fixedly connected to the bottom of the filter box 12, an air inlet is provided on the outer wall of one side of the filter box 12, an air inlet pipe 7 is fixedly connected inside the filter box 12 and located on the outside of one side of the air inlet, a rotating shaft 72 is rotatably connected inside the air inlet, a baffle 8 is fixedly connected to the outer wall of the rotating shaft 72, a backwash controller 6 is fixedly connected to the outer wall of the filter box 12, a diaphragm valve 11 is rotatably connected to the outer wall of the filter box 12, the diaphragm valve 11 is electrically connected to the backwash controller 6, and one end of the diaphragm valve 11 located inside the filter box 12 is fixedly connected to the conical filter element rotating wing;

[0030] The dust collecting device 2 is a kind of dust collecting device which is used for filtering dust particles. ...

[0031] By such an arrangement, when performing dust collection operations, the incoming gas is disturbed by the baffle 8, which can reduce the movement speed of the incoming gas and slow down the movement speed of the dust. At this time, due to the gravity sedimentation effect, the coarse particles of dust in the gas fall directly into the dust collection box 9, thereby playing a role of pre-dust removal, and can avoid excessive dust adhering to the filter element, thereby reducing the frequency of cleaning the filter element and improving work efficiency.

[0032] Please refer to the attached picture Figure 2 、 Figure 3 、 Figure 4 As shown, a slide groove 71 is provided at the top of the air inlet pipe 7, a slider 711 is slidably installed in the slide groove 71, and a connecting frame 73 is fixedly connected to the bottom of the slider 711. The connecting frame 73 is adapted to the size of the air inlet pipe 7, and cleaning cotton 74 is fixedly connected to the outer walls of the connecting frame 73. The cleaning cotton 74 abuts against the inner wall of the air inlet pipe 7;

[0033] Through the above technical solution, when performing dust collection operations, the gas containing dust will enter the air inlet, and the baffle 8 will rotate upward under the action of wind speed. During the rotation of the baffle 8, its side wall will contact the connecting frame 73 and push the connecting frame 73 to the side away from the air inlet. During the movement of the connecting frame 73, the cleaning cotton 74 on the outside of the connecting frame 7 can wipe and clean the inner wall of the air inlet pipe 7, thereby removing large particles of dust that may be attached to the inner wall of the air inlet pipe 7, thereby avoiding excessive dust adhering to the inner wall of the air inlet pipe 7, resulting in backflow, and thus ensuring the dust treatment effect.

[0034] Please refer to the attached picture Figure 3 、 Figure 4As shown, the inner wall of the slide 71 is provided with two groups of limiting grooves 75, which are symmetrically arranged relative to the slider 711. The outer walls of the slider 711 on both sides near the limiting grooves 75 are fixedly connected to limiting blocks 76, which are slidably installed in the limiting grooves 75. The size of the limiting blocks 76 and the limiting grooves 75 are adapted to each other.

[0035] Through the above technical solution, when performing dust collection operations, the connecting frame 73 will move toward the inside of the filter box 12 under the drive of the baffle 8. During this process, the slider 711 will drive the limit block 76 to move in the limit groove 75. At this time, the limit block 76 can limit the slider 711 and the connecting frame 73, preventing the connecting frame 73 from rotating or tilting upward when driven by the baffle 8, thereby ensuring that the cleaning cotton 74 outside it has good contact with the inner wall of the air inlet pipe 7 during the entire process, thereby ensuring the dust cleaning effect.

[0036] Please refer to the attached picture Figure 3 、 Figure 4 As shown, a spring 77 is fixedly connected to the outer wall of the slider 711 on the side away from the baffle 8, and one end of the spring 77 away from the slider 711 is fixedly connected to the inner wall of the slide groove 71. A limiting rod 78 is fixedly connected to the slide groove 71, and the spring 77 is sleeved on the outside of the limiting rod 78. A through hole 79 is formed on the outer wall of the slider 711 on the side close to the baffle 8. The through hole 79 is set through the slider 711, and the limiting rod 78 is set in the through hole 79;

[0037] With the above technical solution, during the dust collection operation, the connecting frame 73 will be driven by the baffle 8 to move toward the inside of the filter box 12. During this process, the slider 711 will squeeze the spring 77. When a dust cleaning operation is completed, no more gas enters the air inlet. At this time, the baffle 8 will rotate downward and reset under the action of its own gravity. At this time, the connecting frame 73 is no longer squeezed by the baffle 8, so it will move to the side of the air inlet and reset under the action of the elastic restoring force of the spring 77, which is convenient for subsequent use.

[0038] And because the spring 77 is sleeved on the outside of the limiting rod 78, the spring 77 will not pop out of the slide groove 71 due to excessive pressure when squeezed, thereby preventing the popped-out spring 77 from blocking the movement of the connecting frame 73.

[0039] Please refer to the attached picture Figure 3 、 Figure 4 As shown, the top of the slider 711 is fixedly connected to a plurality of U-shaped plates 721, and the U-shaped plates 721 are located between the slider 711 and the upper wall of the chute 71. Each of the U-shaped plates 721 is rotatably connected to a roller 722, and the roller 722 abuts against the upper wall of the chute 71.

[0040] Through the above technical solution, when performing dust collection operations, the movement of the slider 711 will drive the roller 722 on its top to rotate synchronously. During this process, the roller 722 can reduce the friction between the slider 711 and the slide groove 71, thereby improving the stability of the movement of the slider 711.

[0041] Please refer to the attached picture Figure 3 As shown, the bottom of the outer wall of the baffle 8 close to the connecting frame 73 is fixedly connected to a mounting seat 81, and a driving rod 82 is rotatably connected to the mounting seat 81;

[0042] Through the above technical solution, when performing dust removal operations, the baffle 8 is affected by the gas wind speed and flipped upward, thereby driving the driving rod 82 to drive the connecting frame 73 to move. The driving rod 82 can indirectly increase the overall length of the baffle 8, so that when the baffle 8 rotates, the connecting frame 73 can be driven deeper into the air inlet pipe 7 through the driving rod 82, thereby increasing its cleaning area, avoiding dust backflow, and improving the dust treatment effect.

[0043] Please refer to the attached picture Figure 5 As shown, the air outlet end of the one-way explosion-proof valve 1 is fixedly connected to the air inlet, the air inlet end of the filter 3 is fixedly connected to the air outlet, and the air outlet end of the filter 3 is fixedly connected to the cooler 4;

[0044] Through the above technical solution, the gas that has undergone initial dust removal in the filter box 12 will enter the filter 3 from the air outlet for further dust removal. The filter 3 can achieve a filtration accuracy of 0.3-0.5μm dust in the gas of more than 99.995%, so that the dust content of the clean gas meets the requirements of a Class 10,000 dust-free workshop. At this time, the temperature of the gas is about 30°C. Finally, the temperature of the treated clean gas is reduced to about 23°C through the cooler 44, and then the clean air enters the lithium battery cell workshop through the return air duct.

[0045] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
