Abstract
Description
Technical Field
[0001] This application relates to the field of solar cell technology, and more specifically, to a wet cleaning tank for TOPCON cells. Background Technology
[0002] In actual production of Topcon solar photovoltaic cells, during the maintenance of wet processing equipment, cleaning the debris at the bottom of the tank is the most difficult and time-consuming task in the entire liquid change process. If the residual and scattered debris at the bottom of the tank is not thoroughly cleaned, it will lead to defects such as debris and liquid in the basket during normal production.
[0003] Currently, most common cleaning devices have a flat bottom, and the cleaning method mainly involves using a vacuum cleaner to clean the entire bottom of the tank piece by piece. This method is not only time-consuming and inefficient, but also prone to flying debris that can cause injury. Utility Model Content
[0004] Therefore, this application proposes a wet cleaning tank for TOPCON batteries, which facilitates the removal of impurities and debris during tank cleaning and reduces the risk of clogging the external discharge port during the cleaning process, thus having good reliability in use.
[0005] The wet cleaning machine tank for TOPCON batteries in some embodiments of this application includes a tank body and an impurity cleaning assembly. The inner side of the bottom wall of the tank body is inclined. A rinsing assembly is provided on the high side of the inclined surface, and a flow slit is provided on the low side of the inclined surface. The flow slit extends vertically through the bottom wall from the inclined surface. An impurity collection tank is provided on the bottom wall. The impurity collection tank is located on the low side of the flow slit. The impurity collection tank has an inlet that communicates with the flow slit, and a first drain outlet is provided on the first side wall of the tank body. When the rinsing assembly sprays water, the cleaning water mixed with impurities flows into the inlet along the inclined surface. The impurities remain in the impurity collection tank, and the remaining wastewater is discharged from the tank body through the flow slit. The impurity cleaning assembly is used to push the impurities in the impurity collection tank out of the first drain outlet.
[0006] According to some embodiments of this application, the wet cleaning tank of the TOPCON battery further includes a plug assembly for sealing the first drain port when drainage is not required.
[0007] According to some embodiments of this application, the plug assembly includes a plug, a sliding plate, and a tension spring. The plug is fixed to the sliding plate, and the tension spring connects the first sidewall and the sliding plate. The tension spring is used to maintain the plug blocking the first drain outlet when sewage discharge is not required.
[0008] According to some embodiments of this application, the plug assembly further includes a guide rod, which is mounted on the first side wall, a tension spring is sleeved on the guide rod, and a sliding plate is slidably mounted on the guide rod along a first direction.
[0009] According to some embodiments of this application, the tank includes a second sidewall, the first sidewall and the second sidewall are disposed opposite to each other along a first direction, the impurity collection tank extends along the first direction, the downstream slit extends along the first direction, the inclined surface extends obliquely in a second direction, and the first direction and the second direction are disposed perpendicular to each other.
[0010] According to some embodiments of this application, the impurity collection tank is further provided with a second drain outlet, which is disposed on the second side wall. The impurity cleaning assembly includes a telescopic push rod, a filter piston, and a top rod. The telescopic push rod is disposed on the same side as the second side wall. The filter piston is installed at the actuating end of the telescopic push rod, and the top rod is located at the end of the filter piston. The telescopic push rod is configured to drive the filter piston to reciprocate within the impurity collection tank. When the filter piston moves toward the first drain outlet, the top rod pushes open the plug of the plug assembly, and the filter piston pushes the impurities in the impurity collection tank out of the first drain outlet. When the filter piston moves toward the second drain outlet, the filter piston pushes the impurities in the impurity collection tank out of the second drain outlet.
[0011] According to some embodiments of this application, the diameter of the push rod is smaller than the diameter of the filter piston.
[0012] According to some embodiments of this application, the impurity collection tank is a cylindrical tank, and the filter piston is a cylindrical piston that matches the shape of the impurity collection tank.
[0013] According to some embodiments of this application, the wet cleaning tank of the TOPCON battery further includes a filter pool disposed on the bottom side of the tank. The filter pool is provided with a porous filter plate, and the wastewater discharged from the downstream slit and the impurity collection tank flows out of the filter pool after being filtered by the porous filter plate.
[0014] According to some embodiments of this application, the shower assembly includes a distribution chamber, a water supply pipe, and a plurality of shower outlets. The water supply pipe is used to supply water to the distribution chamber, and the plurality of shower outlets are spaced apart along the length of the distribution chamber. The shower outlets are used to rinse the interior of the tank with cleaning water.
[0015] Compared with existing technologies, this solution has the following advantages:
[0016] In the wet cleaning machine tank of the TOPCON battery in this application embodiment, impurities and debris accumulate in the impurity collection tank during cleaning. Since the downstream slit and the impurity collection tank are set separately, the process of pushing the impurities in the impurity collection tank out of the first drain outlet will not have any impact on the downstream slit, thereby ensuring that the downstream slit is always unobstructed and the wastewater can always be discharged from the downstream slit. This reduces the risk of clogging the drain outlet during the process of cleaning impurities and debris, and has good reliability in use.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] like Figures 1 to 7 As shown, the wet cleaning machine tank 100 of the TOPCON battery in this embodiment includes a tank 110 and an impurity cleaning component 120. The inner side of the bottom wall 111 of the tank 110 is a slope 1111. A rinsing component 160 is provided on the high side of the slope 1111, and a flow slit 114 is provided on the low side of the slope 1111. The flow slit 114 extends vertically through the bottom wall 111 from the slope 1111. An impurity collection tank 130 is provided on the bottom wall 111. The impurity collection tank 130 is located on the low side of the flow slit 114. The impurity collection tank 130 is provided with a sludge inlet 131 that communicates with the flow slit 114, and a first sludge outlet 132 is provided on the first side wall 112 of the tank 110. When the rinsing assembly 160 sprays water, the cleaning water mixed with impurities flows into the inlet 131 along the inclined surface 1111. The impurities remain in the impurity collection tank 130, and the remaining wastewater is discharged from the tank body 110 through the downflow slit 114. The impurity cleaning assembly 120 is used to push the impurities in the impurity collection tank 130 out of the first drain outlet 132.
[0030] The downward flow seam 114 penetrates the bottom wall 111 in the vertical direction Z, extends upward to the inclined surface 1111, and extends downward to the bottom surface 1112 of the bottom wall 111.
[0031] The inlet 131 is located on the side of the impurity collection tank 130 facing the inclined surface 1111 and the downward flow slit 114, to fully receive wastewater containing impurities and debris. The width of the downward flow slit 114 in the first direction X is smaller than the diameter of the impurities that need to enter the impurity collection tank 130. The cleaning water flows from the high side to the low side along the inclined surface 1111, and its own flow velocity can carry the impurities into the inlet 131 of the impurity collection tank 130.
[0032] In the wet cleaning machine tank 110 of the TOPCON battery in this embodiment, impurities and debris accumulate in the impurity collection tank 130 during cleaning. Since the downstream slit 114 and the impurity collection tank 130 are set separately, the process of pushing the impurities in the impurity collection tank 130 out of the first drain outlet 132 will not have any impact on the downstream slit 114, thereby ensuring that the downstream slit 114 is always unobstructed and that wastewater can always be discharged from the downstream slit 114. This reduces the risk of clogging the drain outlet during the cleaning of impurities and debris, and has good reliability in use.
[0033] In some embodiments of this application, the wet cleaning tank 100 of the TOPCON battery also includes a plug assembly 140 for sealing the first drain port 132 when drainage is not required.
[0034] This configuration allows the impurity collection tank 130 to maintain a sealed internal space when sewage discharge is not required, thus reducing pollution to the surrounding environment.
[0035] In some embodiments of this application, the plug assembly 140 includes a plug 141, a slide plate 142, and a tension spring 143. The plug 141 is fixed to the slide plate 142, and the tension spring 143 connects the first sidewall 112 and the slide plate 142. The tension spring 143 is used to maintain the plug 141 blocking the first drain outlet 132 when sewage discharge is not required.
[0036] With this configuration, the plug 141 can automatically seal the first drain outlet 132 when sewage discharge is not required, maintaining a sealed internal space in the impurity collection tank 130. When sewage discharge is required, the plug 141 can be pushed out by external force. The operation is simple and the assembly cost is very low.
[0037] In some embodiments of this application, the plug assembly 140 further includes a guide rod 144, which is mounted on the first sidewall 112, a tension spring 143 is sleeved on the guide rod 144, and a sliding plate 142 is slidably mounted on the guide rod 144 along the first direction X.
[0038] There are two guide rods 144, which are spaced apart on both sides of the plug 141; correspondingly, there are also two tension springs 143, which are arranged one-to-one with the guide rods 144.
[0039] With this configuration, the slide plate 142 can be guided to move the plug 141 along the first direction X toward or away from the first drain outlet 132.
[0040] In some embodiments of this application, the tank 110 includes a second sidewall 113, the first sidewall 112 and the second sidewall 113 are disposed opposite to each other along the first direction X, the impurity collection tank 130 extends along the first direction X, the downstream slit 114 extends along the first direction X, the inclined surface 1111 extends obliquely in the second direction Y, and the first direction X and the second direction Y are disposed perpendicular to each other.
[0041] The tank 110 also includes a third side wall and a fourth side wall, which are arranged opposite each other along the second direction Y. The four side walls and the bottom wall 111 enclose the tank 110, and the shower assembly 160 is installed on the third side wall.
[0042] With this configuration, the direction of the inclined flow of the cleaning water is perpendicular to the extension direction of the downflow slit 114. The downflow slit 114 extends in the same direction as the impurity collection tank 130, which can fully receive the inclined wastewater, thereby accumulating impurities and debris in the impurity collection tank 130, and the remaining wastewater is discharged from the downflow slit 114 in a timely manner.
[0043] In some embodiments of this application, the impurity collection tank 130 is further provided with a second drain port 133, which is disposed on the second side wall 113. The impurity cleaning assembly 120 includes a telescopic push rod 121, a filter piston 122, and a push rod 123. The telescopic push rod 121 is disposed on the same side as the second side wall 113. The filter piston 122 is installed at the actuating end of the telescopic push rod 121, and the push rod 123 is located at the end of the filter piston 122. The telescopic push rod 121 is configured to drive the filter piston 122 to reciprocate within the impurity collection tank 130. When the filter piston 122 moves toward the first drain port 132, the push rod 123 pushes open the plug 141 of the plug assembly 140, and the filter piston 122 pushes the impurities in the impurity collection tank 130 out of the first drain port 132. When the filter piston 122 moves toward the second drain port 133, the filter piston 122 pushes the impurities in the impurity collection tank 130 out of the second drain port 133.
[0044] The telescopic push rod 121 is a multi-stage telescopic cylinder or electric cylinder, and is mounted on the outer side of the second side wall 113 or on other fixedly mounted frames. The filter piston 122 has a plurality of first filter holes 1221, which penetrate the filter piston 122 along the first direction X. The diameter of the first filter hole 1221 is smaller than the diameter of the impurity debris, so as to be able to push the impurity debris to move within the impurity collection tank 130.
[0045] With this configuration, impurity debris can be pushed out in both the front and rear directions of the impurity collection tank 130, improving the discharge efficiency and effect of impurity debris.
[0046] In some embodiments of this application, the diameter of the push rod 123 is smaller than the diameter of the filter piston 122, so that the plug 141 can be effectively pushed open and the filter piston 122 can be allowed to reciprocate in the first direction X within the impurity collection groove 130.
[0047] In some embodiments of this application, the impurity collection tank 130 is a cylindrical tank, and the filter piston 122 is a cylindrical piston that matches the shape of the impurity collection tank 130.
[0048] The impurity collection tank 130 is set as a cylindrical tank with a smooth transition arc surface inside, which reduces the resistance to water flow and has a large internal space.
[0049] In other embodiments, the impurity collection groove 130 may also be a square groove, a hexagonal groove, or other shapes.
[0050] In some embodiments of this application, the wet cleaning tank 100 of TOPCON battery also includes a filter tank 150, which is disposed on the bottom side of the tank 110. The filter tank 150 is provided with a porous filter plate 152. The wastewater discharged from the downflow slit 114 and the impurity collection tank 130 flows out of the filter tank 150 after being filtered by the porous filter plate 152.
[0051] The filter tank 150 has a tank body 151 including an outer peripheral wall and a porous filter plate 152. The porous filter plate 152 is the bottom wall of the filter tank 150. The outer peripheral wall and the porous filter plate 152 together enclose the tank body 151.
[0052] Wastewater and debris discharged from the downstream slit 114, the first sewage outlet 132, and the second sewage outlet 133 all enter the filter tank 150.
[0053] The diameter of the second filter hole 1521 of the porous filter plate 152 is smaller than the diameter of the impurities and debris to be filtered, so as to further intercept the impurities and debris on the surface of the porous filter plate 152, and the wastewater after secondary filtration flows out of the pool body 151.
[0054] In some embodiments of this application, the shower assembly 160 includes a distribution chamber 161, a water supply pipe 162, and a plurality of shower ports 163. The water supply pipe 162 is used to supply water to the distribution chamber 161, and the plurality of shower ports 163 are spaced apart along the length of the distribution chamber 161. The shower ports 163 are used to rinse the interior of the tank 110 with clean water.
[0055] The length of the distribution chamber 161 extends along the first direction X, and multiple shower outlets 163 are spaced apart along the first direction X.
[0056] With this configuration, cleaning water can be evenly sprayed along the first direction X on the high side of the inclined plane 1111, thereby improving the cleaning effect.
[0057] The working principle of the wet cleaning tank 100 for TOPCON batteries in this embodiment is as follows:
[0058] When cleaning is required, the water supply pipe 162 flows out from multiple shower ports 163 after being diverted by the distribution chamber 161, rinsing the impurities and debris on the inclined surface 1111. The impurities and debris are carried by the water flow through the downstream slit 114 and then enter the impurity collection tank 130 from the sewage inlet 131. The telescopic push rod 121 drives the filter piston 122 to move along the first direction X towards the first sewage outlet 132, pushing the impurities and debris in the impurity collection tank 130 towards the first sewage outlet 132. When the push rod 123 contacts the plug 141, the push rod 123 pushes the plug 141 open, and the impurities and debris are discharged from the first sewage outlet 132.
[0059] The telescopic push rod 121 drives the filter piston 122 to retract along the first direction X and move towards the second drain port 133. At this time, if there are still impurities and debris remaining on the inclined surface 1111, the impurities and debris will continue to flow into the impurity collection tank 130 under the action of water flow. The filter piston 122 pushes the impurities and debris in the impurity collection tank 130 towards the second drain port 133, and the impurities and debris are discharged from the second drain port 133.
[0060] The filter piston 122 is positioned near the second drain port 133 to block the second drain port 133;
[0061] After the telescopic push rod 121 drives the filter piston 122 away from the first drain port 132, the plug 141 automatically resets under the action of the tension spring 143 to seal the first drain port 132.
[0062] Impurities and debris discharged from the first discharge port 132 and the second discharge port 133, as well as wastewater flowing out from the downstream slit 114, all fall into the filter tank 150. After being filtered by the porous filter plate 152, the impurities and debris accumulate on the porous filter plate 152. The filter tank 150 can then be removed to discharge the impurities and debris.
[0063] During the cleaning process described above, as impurities and debris enter the impurity collection tank 130 through the inlet 131, they are pushed out from the first outlet 132 and the second outlet 133 into the filter tank 150 under the reciprocating motion of the filter piston 122. The impurities and debris can then be discharged by removing the filter tank 150. Throughout the entire process, the downstream slit 114 remains unobstructed, reducing the possibility that impurities and debris may completely block the outlet and require manual cleaning, thus providing good reliability.
[0064] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
