DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] A large amount of organic waste gas will be generated when processing topcon battery cells, so a regenerative thermal oxidizer is needed to treat the organic waste gas. Most existing regenerative thermal oxidizers will set up a pre-treatment process when treating organic waste gas, that is, to treat larger particles in the organic waste gas. Most of them use filter screens 33 to filter larger particles. Most existing filter screens 33 are set to be detachable, but there are many larger particles in the organic waste gas, which can easily clog the filter holes of the filter screen 33. The staff needs to waste a lot of time on disassembling the filter screen 33 for cleaning, which is very cumbersome. In the specific scheme disclosed in the scheme, the above problem is solved by a regenerative thermal oxidizer for topcon battery cell processing.

[0028] The regenerative thermal oxidation furnace for processing topcon battery cells is provided with a regenerative oxidation furnace body 1, on which a ventilation duct 2 is installed to realize the entry of waste gas and the discharge of treated gas, and a waste gas treatment device 3 is provided on the connecting track of the ventilation duct 2 so as to filter out impurities mixed in the gas before the waste gas enters the regenerative oxidation furnace body 1, and during the rotation and cleaning process of the filter screen 33, the equipment does not need to be shut down and can maintain a continuous operation state, thereby ensuring the continuity and production efficiency of the topcon battery cell processing process. At the same time, the design of the discharge chute roller 36 allows the particulate matter after cleaning to be discharged in an orderly manner when the equipment is in working condition.

[0029] like Figure 1-Figure 5 As shown, the exhaust gas treatment device 3 includes a treatment box 31 installed at one end of the ventilation pipe 2 and connected thereto, and an exhaust gas inlet 37 and a waste material outlet 38 are provided on the treatment box 31 to establish an output channel for gas to flow inward and waste to flow outward. An exhaust gas treatment suspension 32 is provided inside the treatment box 31, and the exhaust gas treatment suspension 32 is installed on the treatment box 31 through a partition. A central axis 39 is installed extending upward from the center of the exhaust gas treatment suspension 32, and the central axis 39 is rotatably connected to the exhaust gas treatment suspension 32. A connecting rod extends from the central axis 39 to connect with the filter screen 33 so that the central axis 39 drives the filter screen 33 to rotate. The central axis 39 penetrates the filter screen 33 and is coaxially connected to the driving motor arranged on the top wall of the treatment box 31. The driving motor drives the central axis 39 to drive the filter screen 33 to rotate. The filter screen 33 for filtering organic waste gas is installed in the exhaust gas treatment suspension 32. The exhaust gas treatment suspension 32 is tangentially fitted with the filter screen 33. A directional scraper 34 is installed, such as Figure 5 As shown, the driving motor drives the filter screen 33 to rotate periodically or continuously and slowly, and cooperates with the fixed scraper to automatically remove large particles accumulated on the surface of the filter screen 33.

[0030] like Figure 3 As shown, the ventilation duct 2 includes an air inlet pipe 21 connected to the treatment box 31 and an exhaust pipe 22 intersecting and connected through a heat exchanger, an exhaust fan 23 is installed on the exhaust pipe 22, and an air inlet fan 24 is installed on the air inlet pipe 21. A ceramic heat storage body is installed in the thermal storage oxidation furnace body 1, a heat storage chamber is installed at the lower end of the ceramic heat storage body, and a burner is installed at the upper end of the ceramic heat storage body. The thermal storage type thermal oxidation furnace integrates key components such as a heat exchanger, a heat storage chamber, a ceramic heat storage body, and a burner to form an integrated organic waste gas treatment system. The waste gas is preheated by the heat exchanger before entering the furnace body, and the heat is recovered by the heat exchanger after treatment, which realizes efficient energy utilization in the waste gas treatment process and reduces energy consumption.

[0031] like Figure 2As shown, a discharge connection section 35 is installed at the lower end of the waste gas treatment suspension 32. The discharge connection section 35 is spherical, and a discharge trough roller 36 for transmitting waste to the outside is rotatably installed inside it. A driving motor for driving the discharge trough roller 36 to rotate is coaxially installed on the discharge trough roller 36. The discharge trough roller 36 includes a roller shaft and a conveying sheet circumferentially installed on the roller shaft. A receiving groove 5 is opened on the roller shaft between adjacent conveying sheets. When the directional scraper 34 scrapes the filter screen 33, the impurity layer attached to the filter screen 33 is scraped off and falls downward, and falls onto the pre-treatment box. The opening of the receiving groove 5 facilitates the collection and carrying of impurities. When the amount of debris in the pre-treatment box is stored to a certain amount, the discharge trough roller 36 rotates to carry the debris that has fallen into the groove of the discharge trough roller 36 out, thereby achieving discharge. The discharge connection section 35 is hollow inside and connected to the processing box body 31. A rubber layer 4 is attached to the inner wall of the discharge connection section 35. The difference between the rotation radius formed by the rotation direction of several conveying sheets and the radius of the discharge connection section 35 is equal to the thickness of the rubber layer 4. The discharge trough roller 36 and the discharge connection section 35 are kept in a tight sealing state through the contact layer, ensuring that in the process of removing impurities, the organic waste gas in the pre-treatment box will not leak to the outside in large quantities.

[0032] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0033] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
