Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically to an air filtration device. Background Technology

[0002] Air is often introduced during the calcination process of battery materials to participate in the oxidation reaction. Therefore, the introduced air needs to be filtered and purified to remove dust, particles and other pollutants from the air. This is to prevent dust, particles and other pollutants from adhering to the surface of the material or mixing into the product, which could lead to increased internal resistance of the battery, increased self-discharge rate, or even internal short circuit.

[0003] For example, patent document CN202057016U discloses an air filtration device, specifically including an air inlet, a housing, and an air outlet connected to the end of a ventilation system. An air filtration component is installed in the housing, which includes an upper housing and a lower housing. The upper housing and the lower housing are connected by a connecting device. A baffle is installed on the inner wall of the lower housing, and the filter component is fixed to the baffle by a fastening device. With the above solution, only a single filter component is installed in the air filtration device, and the air is filtered only once by the filter component, resulting in poor air filtration effect.

The air guide element is connected to one end of the sleeve and has multiple exhaust pipes arranged along the circumference of the sleeve. The multiple exhaust pipes are used to guide the air inside the sleeve to the bottom of the annular cavity. The adsorption unit includes a gravel section disposed within an annular cavity and located above the exhaust ports of multiple exhaust pipes.

[0006] In one embodiment, the filter element includes a partition and a plurality of cloth bags. The partition is installed inside a sleeve and divides the sleeve into a filter chamber and an exhaust chamber. The plurality of cloth bags are disposed in the filter chamber and connected to the partition, and the opening of each cloth bag corresponds to a through hole on the partition. In one embodiment, the air guide includes a cover body, which is fixedly connected to the sleeve. The cover body and the sleeve form an annular air guide cavity. One end of the sleeve is provided with a plurality of air dissipation holes. The exhaust cavity is connected to the annular air guide cavity through the plurality of air dissipation holes. A plurality of exhaust pipes are fixedly connected to the cover body and connected to the annular air guide cavity.

[0007] In one embodiment, the dust removal unit further includes a back-blowing component, which includes a jet nozzle and a high-pressure air tank.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] To address the technical problem of poor air filtration efficiency in existing air filtration devices, this solution provides an air filtration device capable of filtering air multiple times, thereby improving the air filtration effect.

[0018] Please see Figures 1-5 , Figures 1-5An air filtration device according to one embodiment of the present invention includes a filter cartridge 1, a dust removal unit 2, and an adsorption unit 3. The dust removal unit 2 includes a sleeve 21, a filter element 22, and an air guide element 23. The sleeve 21 is connected to the filter cartridge 1, and one end of the sleeve 21 extends into the filter cartridge 1, forming an annular cavity with the filter cartridge 1. The filter element 22 is installed inside the sleeve 21 and can filter the air delivered to the sleeve 21. The air guide element 23 is connected to one end of the sleeve 21 and has multiple exhaust pipes arranged circumferentially along the sleeve 21. The multiple exhaust pipes are used to guide the air inside the sleeve 21 to the bottom of the annular cavity. The adsorption unit 3 includes a gravel section 31, which is disposed in the annular cavity and located above the exhaust ports of the multiple exhaust pipes.

[0019] In actual use, air is delivered to the sleeve 21 through the air inlet at the other end of the sleeve 21, and the filter element 22 can perform the first filtration of the air. The filtered air is guided to the bottom of the annular cavity through multiple exhaust pipes and is evenly dispersed in the annular cavity. During the rising process, the air comes into contact with the gravel section 31 for the second filtration. The filtered air can be discharged from the air outlet at the top of the filter cylinder 1.

[0020] It should be noted that the filter element 22 is not limited to a specific structure. In one embodiment, The filter element 22 includes a partition 221 and a plurality of cloth bag tubes 222. The partition 221 is installed inside the sleeve 21 and divides the sleeve 21 into a filter chamber and an exhaust chamber. The plurality of cloth bag tubes 222 are disposed in the filter chamber and connected to the partition 221, and the opening of each cloth bag tube 222 corresponds to each through hole on the partition 221. It is understandable that the filter chamber is connected to the air inlet at the other end of the sleeve 21. Air is delivered to the filter chamber through the air inlet, and multiple bag cylinders can filter the air. The filtered air then enters the exhaust chamber.

[0021] It should be noted that, in order to ensure that the air can be evenly dispersed in the annular cavity, the air guide 23 specifically includes a cover 231, which is fixedly connected to the sleeve 21. The cover 231 and the sleeve 21 enclose an annular air guide cavity, and one end of the sleeve 21 is provided with a plurality of air dissipation holes 21a. The exhaust cavity is connected to the annular air guide cavity through the plurality of air dissipation holes 21a. A plurality of exhaust pipes 232 are fixedly connected to the cover 231 and connected to the annular air guide cavity.

[0022] Based on the above solution, in order to facilitate the cleaning of dust on multiple bag cylinders, in one embodiment, the dust removal unit 2 further includes a back-blowing component 24. The back-blowing component 24 includes a jet nozzle 241 and a high-pressure air storage tank 242. The jet nozzle 241 is installed in the exhaust chamber and has multiple jet nozzles, each of which corresponds to the opening of each bag cylinder 222. The jet nozzle 241 is connected to the high-pressure air storage tank 242.

[0023] Understandably, high-pressure airflow is output through the high-pressure air tank 242, and the high-pressure airflow is ejected through multiple nozzles on the jet unit 241. The high-pressure gas can shake off the dust adsorbed on the cloth bag cylinder.

[0024] In addition, the other end of the sleeve 21 is provided with a dust discharge pipe, and a valve is provided on the dust discharge pipe. When the valve is opened, the dust can be discharged through the dust discharge pipe.

[0025] It should be noted that, based on the above scheme, the adsorption unit 3 also includes a tourmaline segment 32, which is disposed in the annular cavity and located above the gravel segment 31. The air is filtered a third time through the tourmaline segment 32, further improving the filtration effect.

[0026] Understandably, gravel can be used as a filter to remove fine particles such as dust, pollen, and mold from the air. Tourmaline generates negative ions, which can effectively eliminate air pollutants and free radicals produced by cigarettes. Exhaust gases from factories and cars, as well as viruses and bacteria in the air, are mostly positively charged. The negative ions generated by tourmaline neutralize these pollutants, causing them to settle.

[0027] It should be noted that, in one embodiment, a first mesh plate 11 and a second mesh plate 12 are spaced apart inside the annular cavity. The first mesh plate 11 is supported on the bottom of the gravel section 31, and the second mesh plate 12 is supported on the bottom of the tourmaline section 32. The first mesh plate 11 has a plurality of first perforations 11a, and the second mesh plate 12 has a plurality of second perforations 12a. Each first perforation 11a and each second perforation 12a corresponds one-to-one. The exhaust pipe extends to the inner bottom of the filter cylinder 1 through the corresponding first perforation 11a and second perforation 12a.

[0028] It is understandable that the aperture of the mesh on the first mesh plate 11 is smaller than the particle size of the gravel, and the aperture of the mesh on the second mesh plate 12 is smaller than the particle size of the tourmaline.

[0029] In addition, based on the above scheme, an air extraction unit 4 is also included, which is connected to the air outlet at the top of the filter cylinder 1.

[0030] Understandably, the exhaust unit 4 is an induced draft fan. By evacuating the cylinder, a negative pressure can be formed at the air inlet end of the sleeve 21.

[0031] In addition, based on the above solution, in order to facilitate the cleaning of gravel section 31 and tourmaline section 32, in one embodiment, a spray unit 5 is also included. The spray unit 5 includes a spray element 51, a liquid extraction element 52 and a liquid storage tank 53. The spray element 51 is installed inside the filter cylinder 1 and located above the tourmaline section 32. The spray element 51 is connected to the liquid storage tank 53 via the liquid extraction element 52.

[0032] Understandably, the storage tank 53 can hold cleaning fluid. The cleaning fluid in the storage tank 53 is pumped to the spray unit 51 through the pumping unit 52, and then sprayed into the filter cartridge 1 through the spray unit 51.

[0033] In one embodiment, in order to enable the cleaning solution to be recycled, the drain end at the bottom of the filter cartridge 1 is connected to the storage tank 53 via a conduit. It should be noted that after the cleaning solution is recycled multiple times, the cleaning solution in the storage tank 53 needs to be replaced to ensure the cleaning effect.

[0034] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
