Description

Technical Field

[0001] This invention relates to the field of gas purification technology, specifically to a device for purifying the exhaust gas of a negative electrode material. Background Technology

[0002] In the production and processing of battery anode materials, granulation is a key step. The granulation process involves loading uniformly mixed materials into a furnace for granulation to obtain semi-finished anode materials. The anode material coating and granulation reactor process generates a large amount of high-temperature flue gas at around 650℃. The main components of the high-temperature flue gas are asphalt powder, tar, and dust.

[0003] In the existing technology, some manufacturers directly treat high-temperature flue gas through comprehensive flue gas treatment devices (such as incinerators, electrostatic precipitators, dust collectors, etc.). When purifying the exhaust gas, it is necessary to filter the impurities in the gas. Existing gas purification devices generally separate impurities directly through centrifugal force. Although this method can separate impurities, the separation effect is limited by relying solely on centrifugal force, and impurities will still remain in the separated gas. Summary of the Invention

[0010] As a further description of the above technical solution: a mounting base is fixedly installed on the top of the purification tank, the drive motor is fixedly installed on the inner wall of the mounting base, a limiting bracket is fixedly installed on the inner wall of the purification tank, and the inner wall of the limiting bracket is rotatably connected to the outer wall of the stirring shaft.

[0013] The beneficial effects of this invention are reflected in:

[0014] Firstly, in this invention, a circulating structure guides the gas containing particulate matter or harmful substances separated by centrifugal force, so that the separated gas moves and accumulates along a preset direction, and then is filtered through a filtration structure, thereby improving the treatment effect of the exhaust gas. At the same time, the circulating structure can filter the gas in a cyclical manner, making the gas treatment more thorough compared to traditional devices.

[0015] Secondly, in this invention, when the gas is delivered to the inside of the filter structure, the rotation of the blades provides the power for the movement of the gas, enabling the gas to effectively pass through the filter screen, thereby ensuring the filtration effect. At the same time, the action of the blades can prevent the gas from flowing back. When the filter structure is performing filtration, it can collect particulate matter or harmful substances in the gas, which is convenient for processing. Moreover, the filter structure is detachable, which is convenient for subsequent cleaning and maintenance.

[0016] Thirdly, in this invention, the scraper can clean the filter screen, avoiding excessive impurities on the filter screen surface that would affect the filtration efficiency. The cooperation of the moving plate and the inclined block enables the scraper to drive the lever to move. When the lever moves, it can clean the scraper itself, preventing impurities from adhering to the scraper and affecting its cleaning effect. Attached Figure Description

[0029] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0031] like Figures 1-10As shown, this embodiment of the invention provides a technical solution: a negative electrode material exhaust gas purification device, including a purification tank 1, a circulation structure 2, a filter structure 3, and a cleaning structure 4. The circulation structure 2 includes a circulation tank 201 inside. A plurality of guide grooves A202 are evenly distributed on the inner wall of the purification tank 1, and a plurality of guide grooves B203 are evenly distributed on the inner wall of the circulation tank 201. The guide grooves B203 are respectively connected to the guide grooves A202. The inner wall of the circulation tank 201... A circular groove 204 is provided, and several guide grooves B203 are connected to the circular groove 204. Several air guide holes 205 are provided on the inner wall of the circulation tank 201, and several air guide holes 205 are connected to the circular groove 204. An air guide pipe 206 is fixedly installed on the inner wall of the air guide hole 205, and a guide cover 207 is fixedly installed on one end of the air guide pipe 206. A through groove 208 is provided at the axis of the inner wall of the circulation tank 201, and several air guide holes 205 are connected to the through groove 208.

[0032] The filter structure 3 includes a base 301. An outer frame 302 is fixedly mounted on the top of the base 301. Several vertical plates 303 are fixedly mounted on the top of the outer frame 302. A baffle 304 is positioned above each vertical plate 303. An outer fixing plate 305 is positioned above each baffle 304. A locking block 306 is fixedly mounted on the top and bottom of each baffle 304. The baffle 304 is engaged with the vertical plate 303 and the outer fixing plate 305 respectively via the locking blocks 306. An inner fixing plate 308 is provided on the inner side of the outer fixing plate 305. A filter screen 307 is fixedly installed between the outer wall of the inner fixing plate 308 and the inner wall of the outer fixing plate 305. A rotating seat 309 is rotatably installed on the inner wall of the inner fixing plate 308. An insertion hole 310 is opened on the inner wall of the rotating seat 309. A connecting rod 311 is fixedly installed at the bottom of the rotating seat 309. Several blades 312 are fixedly installed on the outer wall of the connecting rod 311. A collection box 313 is slidably installed between the base 301 and the outer frame 302.

[0033] Specifically, centrifugal force separates the exhaust gas containing particulate matter or harmful substances. The separated gas moves to the inner edge of the purification tank 1. When the gas reaches the edge, it enters the inner side of the guide groove A202. Since the guide grooves A202 and B203 are spiral, the gas moves downward to the inner side of the circular groove 204 under the action of the guide grooves A202 and B203. After entering the circular groove 204, the gas enters the interior of the guide hole 205 under the action of the guide cover 207 and the air guide pipe 206. Then, the gas gathers on the inner side of the through groove 208 along the air guide hole 205 and is filtered by the filter structure 3. The filtered particulate matter or harmful substances gather inside the filter structure 3, and the filtered gas re-enters the interior of the purification tank 1 for further filtration.

[0034] When gas containing particulate matter or harmful substances enters the inner wall of the channel 208, the rotating seat 309 will rotate together with the stirring shaft 6 under the action of the extension rod 8 and the plug rod 9. When the rotating seat 309 rotates, it will drive the blades 312 to rotate through the connecting rod 311. When the blades 312 rotate, they will provide power for the movement of the gas, causing the gas to move towards the filter screen 307, thereby effectively filtering particulate matter or harmful substances in the gas. At the same time, the blades 312 will make the gas move along a preset method to prevent backflow. The filtered particulate matter or harmful substances will fall into the collection box 313 for collection. The collection box 313 can be pulled out from the inside of the outer frame 302 for easy processing of the collected impurities. The baffle 304 is connected to the vertical plate 303 and the outer fixing plate 305 through the locking block 306. Removing the baffle 304 can disassemble the filter structure 3 for easy cleaning.

[0035] In another embodiment of the present invention, the cleaning structure 4 includes an inclined block 401 and a scraper 402. There are two scrapers 402. A movable plate 403 is slidably installed on the inner wall of the scraper 402. An elastic element 404 is fixedly installed between one end of the movable plate 403 and the inner wall of the scraper 402. A plurality of paddles 405 are fixedly installed on the outer wall of the movable plate 403. The outer wall of the paddles 405 is in contact with the outer wall of the scraper 402. A buffer limiting plate 406 is fixedly installed on the outer wall of the scraper 402. The buffer limiting plate 406 is engaged with the movable plate 403.

[0036] Specifically, when the connecting rod 311 rotates, it drives the scraper 402 to rotate. The scraper 402 cleans the surface of the filter screen 307, ensuring its filtration efficiency. As the scraper 402 rotates, the moving plate 403 periodically contacts the inclined block 401. When the moving plate 403 contacts the inclined block 401, it moves. At this time, the elastic element 404 is in a contracted state. The movement of the moving plate 403 drives the lever 405 to move. 05 During movement, it will clean the impurities adhering to the scraper 402 to prevent impurities from remaining on the scraper 402. When the moving plate 403 passes the inclined block 401, the moving plate 403 will be reset under the action of the elastic element 404. The buffer limit plate 406 can limit the moving plate 403 to prevent the moving plate 403 from sliding out. At the same time, the buffer limit plate 406 is elastic and can buffer the moving plate 403 when it is reset to prevent the moving plate 403 from being damaged by collision during reset.

[0037] In another embodiment of the present invention, the outer wall of the collection box 313 is provided with a groove 314, the outer wall of the base 301 is symmetrically fixedly installed with mounting parts 315, the inner wall of the mounting parts 315 is provided with bolts 316, the outer wall of the inner fixing plate 308 and the inner wall of the outer fixing plate 305 are symmetrically fixedly installed with stabilizing plates 317, and the inner wall of the bottom of the base 301 is fixedly installed with a rotating plate 318.

[0038] Specifically, the collection box 313 can be pulled out by the groove 314, and the mounting part 315 can be connected to the circulation tank 201 by the bolt 316, thereby connecting the base 301 to the circulation tank 201. After the bolt 316 is released, the filter structure 3 can be taken out, which is convenient for cleaning and maintenance of the filter structure 3.

[0039] In another embodiment of the present invention, the circulation tank 201 is fixedly installed at the bottom of the purification tank 1, and the base 301 is fixed to the circulation tank 201 by the provided mounting parts 315 and bolts 316. The outer frame 302, the collection box 313, the vertical plate 303, the baffle 304 and the outer fixing plate 305 are all located inside the through groove 208. The inclined block 401 is fixedly installed on the inner wall of the outer fixing plate 305, and the scraper 402 is fixedly installed on the outer wall of the connecting rod 311.

[0040] Specifically, the circulation tank 201 and the purification tank 1 are connected to form a sealed environment to purify the exhaust gas. The filter structure 3 is inside the through groove 208, thereby achieving gas filtration inside the through groove 208.

[0041] In another embodiment of the present invention, a drive motor 5 is provided above the purification tank 1, a stirring shaft 6 is fixedly installed at the output end of the drive motor 5, a plurality of stirring plates 7 are fixedly installed on the outer wall of the stirring shaft 6, an extension rod 8 is fixedly installed at one end of the stirring shaft 6, a plug rod 9 is fixedly installed at one end of the extension rod 8, and the plug rod 9 is inserted into the inner wall of the plug hole 310.

[0042] Specifically, the drive motor 5 drives the stirring shaft 6 to rotate, and the stirring shaft 6 drives the stirring plate 7 to rotate. When the stirring plate 7 rotates, it drives the gas to rotate and form a rotating airflow. The rotating airflow generates centrifugal force to achieve the separation effect. The plug rod 9 is inserted into the plug hole 310. When the stirring shaft 6 rotates, it drives the plug rod 9 through the extension rod 8. The plug rod 9 drives the rotating seat 309 to rotate through the cooperation with the plug hole 310. Through the cooperation of the plug rod 9 and the plug hole 310, both transmission and separation can be achieved.

[0043] In another embodiment of the present invention, a mounting base 10 is fixedly installed on the top of the purification tank 1, the drive motor 5 is fixedly installed on the inner wall of the mounting base 10, and a limiting bracket 11 is fixedly installed on the inner wall of the purification tank 1. The inner wall of the limiting bracket 11 is rotatably connected to the outer wall of the stirring shaft 6.

[0044] Specifically, the drive motor 5 is fixed by the mounting base 10, which provides power to the drive motor 5 so that the drive motor 5 can stably provide power for the operation of the device. The limiting bracket 11 is used to limit the stirring shaft 6, increase the stability of the stirring shaft 6, and prevent the stirring shaft 6 from deviating.

[0045] In another embodiment of the present invention, an air inlet pipe 12 and an exhaust pipe 14 are fixedly installed on the inner wall of the purification tank 1, a fixing bracket A13 is fixedly installed between the air inlet pipe 12 and the outer wall of the purification tank 1, and a fixing bracket B15 is fixedly installed between the exhaust pipe 14 and the outer wall of the purification tank 1.

[0046] Specifically, exhaust gas is transported into the equipment through intake pipe 12. After the gas is purified, it is discharged through exhaust pipe 14 for further processing. Fixing bracket A13 and fixing bracket B15 fix intake pipe 12 and exhaust pipe 14 respectively, increasing the stability of the connection between intake pipe 12 and exhaust pipe 14.

[0047] In another embodiment of the present invention, a plurality of support legs 16 are fixedly installed at the bottom of the circulation tank 201, and support feet 17 are fixedly installed at the bottom of the support legs 16. An annular plate 18 is fixedly installed between the inner walls of the plurality of support legs 16.

[0048] Specifically, the equipment is supported by the support legs 16 to keep it at a suitable working height. The support feet 17 increase the contact area between the support legs 16 and the ground, thereby increasing the overall stability of the equipment. The ring plate 18 connects the support legs 16, increasing their stability.

[0049] Working Principle: During use, the exhaust gas requiring purification enters the purification tank 1 through the inlet pipe 12. The drive motor 5 drives the stirring plate 7 to rotate via the stirring shaft 6. The stirring plate 7 stirs the gas, forming a rotating airflow. This rotating airflow generates centrifugal force, causing particulate matter or harmful substances in the gas to be thrown towards the wall of the purification tank 1 due to inertia. The relatively clean gas continues to rotate and flows towards the central area of ​​the purification tank 1. When particulate matter or harmful substances are thrown towards the wall of the purification tank 1, they move downward into the circular groove 204 under the action of the guide grooves A202 and B203. After entering the circular groove 204, the particulate matter or harmful substances enter the air guide hole 205 under the action of the guide cover 207, and then enter the through groove 208 for filtration. The filtered gas re-enters the purification tank 1 and undergoes the above steps again for filtration. After entering the channel 208, the blades 312 rotate with the stirring shaft 6, generating airflow that causes particulate matter or harmful substances to flow towards the filter screen 307, effectively filtering the particulate matter or harmful substances while preventing backflow. The cleaning structure 4 also rotates, cleaning the surface of the filter screen 307 to ensure its purification efficiency. The filtered particulate matter or harmful substances fall into the collection box 313 for collection. The collection box 313 is detachable for easy processing of the collected impurities. When the cleaning structure 4 rotates, the moving plate 403 periodically contacts the inclined block 401. When the moving plate 403 contacts the inclined block 401, the pressure of the inclined block 401 causes the moving plate 403 to move the paddle plate 405, which cleans the impurities remaining on the surface of the scraper 402.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
