[0040] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0041] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in the present application may include a battery module or a battery pack.

[0042] The battery cell may be a secondary battery cell, which refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0043] The battery cells can be lithium-ion battery cells, sodium-ion battery cells, sodium-lithium-ion battery cells, lithium metal battery cells, sodium metal battery cells, lithium-sulfur battery cells, magnesium-ion battery cells, nickel-hydrogen battery cells, nickel-cadmium battery cells, lead-acid battery cells, etc., which are not limited in the embodiments of the present application.

[0044] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly includes a positive electrode sheet, a negative electrode sheet and a separator. A battery cell mainly works by the movement of metal ions between the positive electrode sheet and the negative electrode sheet. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive current collector. The positive current collector includes a positive current collector and a positive electrode ear connected to the positive current collector.

[0045] During the production process of battery cells, lithium battery materials usually need to be sintered through a sintering system to ensure the production requirements of electrode assemblies. When the sintering system sinters lithium battery materials, corresponding tail gas will be generated. If the tail gas is discharged directly, some harmful substances will pollute the environment. Therefore, before the tail gas is discharged, a corresponding tail gas treatment device needs to be set up to filter the tail gas, filter out harmful substances, and reduce the probability of environmental pollution.

[0046] The applicant noticed that the filter components of the exhaust gas treatment device in the related art are not easy to replace, which affects production efficiency. Further research found that the filter components of the exhaust gas treatment device in the related art are installed inside its box. Since the filter components are consumables, they need to be disassembled and separated from the box after a period of use for maintenance or replacement. In the related art, the matching method between the filter components and the box of the exhaust gas treatment device is such that when replacing the filter components, the operator needs to enter the interior of the treatment device to remove the filter components, which is difficult to disassemble and is not conducive to ensuring the personal safety of the operator.

[0047] In order to alleviate the problem of inconvenient disassembly and assembly of the exhaust gas treatment device, the applicant has found that by changing the matching method between the box and the filter component, the filter component can be disassembled and assembled by a pull-out method to ensure the maintenance and replacement needs of the filter component. At the same time, there is no need for the operator to enter the interior of the box, which reduces the difficulty of replacing the filter component and ensures the personal safety of the operator.

[0048] Based on the above considerations, in order to alleviate the problem of inconvenient disassembly and assembly of the exhaust gas treatment device, the applicant has designed an exhaust gas treatment device after in-depth research.

[0049] See also Figures 1 to 3 As shown, the exhaust gas treatment device includes a housing 10 and a filter component 20, wherein the housing 10 has a receiving chamber 11, an inlet 12 and an outlet 13 connected to the receiving chamber 11.

The filter component 20 can be inserted into the accommodating cavity 11 or pulled out from the accommodating cavity 11 through the plug-in opening 14. The shape and number of the plug-in opening 14 can be determined according to the shape and number of the filter component 20.

[0061] At the same time, the arrangement of two or more filter components 20 allows the filter components 20 to be pulled out and replaced one by one from the box body 10 when they are replaced, so that the exhaust gas treatment device can also complete the replacement of the filter components 20 without stopping the machine. At the same time, when a single filter component 20 is pulled out for replacement, the remaining filter components 20 can still play a filtering role, avoiding that part of the exhaust gas is discharged without being filtered, and optimizing the filtering effect. In addition, the arrangement of two or more filter components 20, when they are synchronously located in the accommodating cavity 11, can achieve multi-layer filtration of the exhaust gas, ensure the filtering effect of harmful substances, and improve the safety of the exhaust gas treatment device.

The filter component 20 includes two filter units 21 spaced apart along the second direction Y, each filter unit 21 is respectively provided with a plug-in port 14, each filter unit 21 is respectively movably connected to the housing 10, and the second direction Y is perpendicular to the first direction X. The filter unit 21 includes a filter net 211 and a frame 212 that encloses the filter net 211, a guide rail 16 is provided in the housing 10, and the frame 212 is respectively slidably matched with the guide rail 16 at both ends of the second direction Y. The first door body 30 is rotatably connected to the housing 10 so that the plug-in port 14 can be switched between an open state and a closed state. When the plug-in port 14 is in a closed state, the first sealing body 50 is clamped between the first door body 30 and the housing 10 and is provided to enclose the plug-in port 14. The second door body 40 is rotatably connected to the housing 10 to open or close the maintenance port 15. A locking component 60 is provided at the first door body 30 and the second door body 40. The locking component 60 is connected between the first door body 30 and the box body 10, and the locking component 60 is connected between the second door body 40 and the box body 10. The locking component 60 can be locked with a bolt with a screwed handrail.

[0089] On the other hand, according to the present application, a sintering device is provided, including the above-mentioned exhaust gas treatment device, which can be used for the sintering of partial structures of electrode components and can ensure the exhaust gas treatment requirements. At the same time, it has all the advantages of the exhaust gas treatment device and is conducive to promotion and use.

[0090] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
