Description

Technical Field

[0001] This application relates to the field of battery cell cleaning technology, and in particular to a cleaning device. Background Technology

[0002] In current tank cleaning equipment, the mainstream approach to achieving filtration recovery is to add a filter screen at the tank drain or install an additional filter in the circulation pipeline. However, this method involves a cumbersome process for obtaining the filtered material, requiring equipment shutdown. This undoubtedly shortens the actual operating time of the equipment, reduces production efficiency, and negatively impacts the continuous and stable operation of the equipment. Taking the grid stripping process as an example, when the amount of grid stripped is large, traditional filtration recovery methods easily lead to clogging and overloading of the entire filtration device, necessitating frequent shutdowns for cleaning. This is insufficient to meet the needs of mass production equipment, severely compressing the effective operating time of the equipment and reducing production efficiency. Utility Model Content

[0003] Based on this, this application provides a cleaning device that solves the problem that the existing cleaning devices require long downtime to remove impurities, resulting in short working time and low efficiency.

[0004] This application provides a cleaning device, comprising: The main tank is used for cleaning the target object; The auxiliary tank is connected to the main tank through a pipe so that the liquid cleaned in the main tank is filtered through the auxiliary tank and then flows back to the main tank for recycling. The sub-tank is provided with a first filter element and a second filter element. The first filter element is inclined to filter the liquid entering the sub-tank. The second filter element is detachably disposed in the sub-tank and is located near the end of the first filter element to receive and filter the liquid and / or solids flowing down from the first filter element.

[0005] Optionally, the height of the lowest point of the second filter element is lower than the height of the highest point of the first filter element.

[0006] Optionally, the end of the first filter element is located above the second filter element.

[0007] Optionally, a support frame is provided in the sub-tank, and the support frame includes a support platform; The second filter element is a filter box with an opening at the top and an outwardly folded flange at the opening. The flange overlaps the support platform so that the filter box is placed on the bracket.

[0008] Optionally, it also includes at least one connector that detachably connects the flange to the support platform.

[0009] Optionally, a handle is provided above the second filter element for removing the second filter element.

[0010] Optionally, mounting portions are provided on opposite sides of the second filter element, through which the second filter element is connected to the handle.

[0011] Optionally, the secondary tank is further provided with a heating element to heat the filtered liquid in the secondary tank.

[0012] Optionally, the secondary tank further includes: The liquid inlet is located on the upper side of the sub-tank and above the first filter element; An overflow port is located on the side of the secondary tank, and the lowest point of the overflow port is higher than or equal to the highest point of the first filter element; and A return port is located on the side or bottom of the sub-tank, and the highest point of the return port is lower than or equal to the bottom of the second filter element.

[0013] Optionally, a liquid level sensor is also provided in the secondary tank, and the height of the liquid level sensor is lower than the height of the lowest point of the support.

[0014] The cleaning equipment of this application includes a main tank and a secondary tank connected by pipes. The secondary tank is equipped with a first filter and a second filter. By using the first and second filters in the secondary tank, liquid entering the secondary tank is first filtered by the first filter. Because the first filter is tilted, impurities accumulated at the first filter to a certain extent or becoming clogged will slide down due to the tilt, reducing the likelihood of clogging and minimizing downtime for cleaning. A second filter is located at the tail end of the first filter. Impurities sliding down from the first filter enter the second filter. The second filter is removable. When the second filter becomes clogged or overloaded with impurities, it can be disassembled for cleaning. The first filter can still filter, and the time required for the second filter to become clogged or overloaded is longer, significantly reducing machine downtime and improving filtration efficiency.

Detailed Implementation

[0017] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0018] As a specific embodiment of this application, such as Figure 1 As shown, this embodiment provides a cleaning device 100. The cleaning device 100 may include a secondary tank 110 and a main tank 200. The main tank 200 is connected to the secondary tank 110 via a pipe 210, so that the cleaned liquid is sent through the pipe 210 into the secondary tank 110 for filtration. The filtered liquid in the secondary tank 110 is then fed back into the main tank 200 through the pipe 210 for recycling. Specifically, a switch and a pump can be designed at the pipe to control the flow rate and volume of the liquid. In this embodiment, the secondary tank 110 is also equipped with a first filter element 120 and a second filter element 130 (see...). Figures 2-4 The first filter element 120 is inclinedly disposed within the sub-tank 110 to filter the liquid entering the sub-tank 110. The second filter element 130 is detachably disposed within the sub-tank 110, and is located near the end of the first filter element 120 to receive and filter the liquid and / or solids flowing down from the first filter element 120.

[0019] Specifically, in this embodiment, a first filter element 120 and a second filter element 130 are provided in the sub-tank 110. This allows liquid entering the sub-tank 110 to first pass through the first filter element 120 for filtration. Because the first filter element 120 is tilted, impurities filtered at the first filter element 120, once accumulated to a certain extent or becoming clogged, will slide down due to the tilt, reducing the likelihood of clogging and minimizing downtime for cleaning. In this embodiment, a second filter element 130 is provided at the tail end of the first filter element 120. Impurities sliding down from the first filter element 120 will enter the second filter element 130. The second filter element 130 is removable. When the second filter element 130 becomes clogged or fully loaded with impurities, it can be disassembled for cleaning. At this time, the first filter element 120 can still perform filtration, and the time required for the second filter element 130 to become clogged or fully loaded is longer, significantly reducing machine downtime and improving filtration efficiency.

[0020] Specifically, in this embodiment, the first filter element 120 can be a filter screen, and the size of the mesh can be designed according to the size of the actual filtered substance. The tilt angle of the first filter element 120 in this embodiment is designed according to the actual filtered substance and the flow rate of the liquid.

[0021] In this embodiment, the second filter element 130 can be a filter box with an upper opening 131. Multiple mesh holes can be provided on the side wall and bottom wall below the opening 131 to ensure that liquid or solid impurities sliding off the tail of the first filter element 120 can enter the filter box through the opening 131 and then be further filtered by the filter box.

[0022] Specifically, in this embodiment, the lowest point of the second filter element 130 is lower than the highest point of the first filter element 120, ensuring that liquid and / or solid matter at the first filter element 120 can enter the second filter element 130.

[0023] As one embodiment, such as Figure 4 and Figure 5 As shown, in this embodiment, the end of the first filter element 120 is located on the side of the opening 131 of the second filter element 130. Of course, the vertical distance between the end of the first filter element 120 and the side of the opening 131 of the second filter element 130 closest to the first filter element 120 should not be too large, so that the liquid and / or solid sliding off the first filter element 120 will fall into the second filter element 130 in a parabolic manner.

[0024] Of course, as a preferred embodiment, the end of the first filter element 120 in this embodiment is located directly above the second filter element 130. This ensures that liquids and / or solids at the end of the first filter element 120 can also enter the second filter element 130 when they fall freely from the end of the first filter element 120.

[0025] As a specific embodiment of this application, such as Figure 3 and Figure 4 As shown, a support 140 is provided inside the sub-tank 110 in this embodiment. The support 140 may include a support platform 141. The first filter element 120 is placed and fixed at the support 140, such that the first filter element 120 is located at the upper-middle position of the sub-tank 110. When liquid enters the sub-tank 110, it first passes through the first filter element 120, and the filtered liquid then flows to the bottom of the sub-tank 110.

[0026] In this embodiment, the second filter element 130 has an outwardly folded flange 132 at its opening 131 (e.g., Figure 5 As shown), the flange 132 overlaps at the support platform 141 so that the filter box is placed at the bracket 140.

[0027] In one embodiment, the second filter element 130 is placed directly on the support platform 141 of the bracket 140 via the flange 132, so that the second filter element 130 can be directly removed from the support platform 141 when it needs to be cleaned or replaced, making the operation simple and convenient.

[0028] In a preferred embodiment, at least one connector 150 is provided at the flange 132 of the second filter element 130 and the support platform 141, and the flange 132 and the support platform 141 are detachably connected together by the connector 150. The connector 150 can fix the second filter element 130 to the support, preventing the second filter element 130 from shifting during use, which would cause liquid and / or solids that have slipped off the first filter element 120 to enter the bottom of the sub-tank 110 through the gap between the second filter element 130 and the bracket 140.

[0029] Specifically, in this embodiment, the connector 150 can be a snap-fit ​​structure disposed between the second filter element 130 and the bracket 140, which detachably connects the second filter element 130 and the bracket 140 together.

[0030] Specifically, such as Figure 4 and Figure 5 As shown, the connector 150 in this embodiment can also be a fastener. After providing through holes at the second filter 130 and the bracket 140, the second filter 130 and the bracket 140 are connected together by the fastener passing through the through holes.

[0031] Preferably, in this embodiment, multiple connectors 150 are provided, which can be evenly arranged on the outer periphery of the opening 131 of the second filter 130.

[0032] As a specific embodiment of this application, such as Figure 5 As shown, a handle 133 is provided above the second filter element 130 in this embodiment for removing the second filter element 130. When the second filter element 130 is clogged or full of impurities, the connector 150 can be loosened first, and the user can directly remove the second filter element 130 from the sub-tank 110 by removing the handle 133, thereby cleaning and washing the second filter element 130.

[0033] Specifically, such as Figure 5 As shown, in this embodiment, mounting portions 134 are provided on opposite sides of the second filter element 130, connecting the second filter element 130 to the handle 133 via the mounting portions 134. In this embodiment, the mounting portion 134 extends outward from the flange 132, and the cross-sectional structure of the mounting portion 134 matches the corresponding cross-sectional structure of the support 140. Connecting the handle 133 to the mounting portion 134 facilitates the connection between the handle 133 and the second filter element 130, while preventing direct connection between the handle 133 and the flange 132 of the second filter element 130, which could lead to deformation of the flange 132 and the formation of a gap between the flange 132 and the support platform 141, allowing impurities to enter the bottom of the sub-tank 110 through the gap.

[0034] As a specific embodiment of this application, such as Figures 2-4 As shown, a heating element 160 is also provided inside the sub-tank 110 in this embodiment to heat the filtered liquid inside the sub-tank 110. The number of heating elements 160 can be designed according to actual conditions, and the heating elements 160 are located near the bottom of the sub-tank 110. By heating the liquid through the heating elements 160, the temperature of the liquid is maintained, thereby ensuring the smooth progress of subsequent steps.

[0035] As a specific embodiment of this application, such as Figure 3 and Figure 4As shown, the secondary tank 110 in this embodiment may further include an inlet 111, an overflow port 112, and a return port 113. In this embodiment, the inlet 111 is located on the upper side of the secondary tank 110, above the first filter element 120. Liquid entering the secondary tank 110 through the inlet 111 directly reaches the first filter element 120 and is filtered by it. The overflow port 112 is located on the side of the secondary tank 110, and the lowest point of the overflow port 112 is higher than or equal to the highest point of the first filter element 120. Preferably, the lowest point of the overflow port 112 and the highest point of the first filter element 120 are at the same horizontal plane. When the liquid in the secondary tank 110 reaches the lowest point of the overflow port 112, the liquid has already exceeded the first filter element 120, and the filtration device 100 no longer has a filtration function; therefore, the height of the overflow port 112 should not be too high. The return port 113 is located on the side or bottom of the sub-tank 110, and the highest point of the return port 113 is lower than the bottom of the second filter element 130. This ensures that the liquid exiting from the return port 113 has been filtered by the first filter element 120 and / or the second filter element 130, guaranteeing the cleanliness of the returned liquid.

[0036] Specifically, such as Figure 4 As shown, in this embodiment, filter screens 114 are provided at both the overflow port 112 and the return port 113 to further filter the liquid and improve the filtration efficiency.

[0037] As a specific embodiment of this application, such as Figure 2 and Figure 4 As shown, a liquid level sensor 170 is also provided in the sub-tank 110 of this embodiment. The height of the liquid level sensor 170 is lower than the height of the top of the bracket 140.

[0038] Specifically, in this embodiment, when the liquid level reaches the level sensor 170, the level sensor 170 will transmit the information, and an audible and visual alarm may occur at the filter device 100. Of course, the level sensor 170 may also transmit the information to the remote control terminal, where a prompt or alarm message will appear, allowing the user to know the liquid level inside the auxiliary tank 110 at all times.

[0039] In this embodiment, the height of the liquid level sensor 170 is the same as the top height of the first support 140. This prevents liquid in the second filter element 130 from flowing out from above the support 140 when the liquid level is higher than this position, thus avoiding impurities in the second filter element 130 from entering the bottom of the secondary tank 110. Therefore, when the liquid level reaches the liquid level sensor 170, the liquid level sensor 170 promptly notifies the user of the liquid level status via an alarm, preventing the liquid in the secondary tank 110 from being contaminated by impurities.

[0040] Specifically, in this embodiment, the main tank 200 can be a device for cleaning battery cells. After the battery cells are cleaned in the main tank 200, the liquid in the main tank 200 is input through pipe 210 to the inlet 111 of the secondary tank 110, and then flows directly to the first filter element 120. After the first filter element 120 filters the liquid, the filtered liquid flows directly into the tank 110 below. Unfiltered liquid and filtered solid impurities slide off from the first filter element 120 or are flushed by the liquid to the second filter element 130, where they are filtered. The liquid then flows down into the secondary tank 110. The filtered liquid then flows out through the return port 113 below the secondary tank 110, and re-enters the cleaning device 200 through pipe 210 for reuse.

[0041] When the second filter element 130 becomes clogged or has excessive solid impurities, it can be cleaned and washed using the extraction handle 133 before being placed back into the bracket 140 within the sub-tank 110. During this process, because the first filter element 120 continuously filters the liquid, it is less prone to clogging under the scouring effect of the liquid, thus reducing downtime for cleaning. Furthermore, while the second filter element 130 is being disassembled and cleaned, the first filter element 120 can still filter, and the second filter element 130 requires a longer time to become clogged or fully loaded, significantly reducing machine downtime and thus increasing equipment operating time and production efficiency. Compared to existing technologies, the sub-tank 110 of this application can save 95% of downtime.
