Description

Technical Field

[0001] The invention relates to the technical field of chemical formation tank cleaning devices, in particular to a cleaning device for broken foil in a chemical formation tank. Background Art

[0002] During the production of aluminum electrolytic capacitors, aluminum foil needs to pass through a formation tank for corrosion and oxidation. During this process, broken foil may fall off and deposit at the bottom of the tank. If not cleaned in time, it will cause a short circuit or contaminate the electrolyte. To clean the broken foil in the formation tank, most manufacturers currently rely mainly on operators to use traditional handheld clamping devices for manual cleaning. Due to the small size and irregular shape of the broken foil, they are easy to stick or spread flat on the bottom of the formation tank, and the clamping head of the clamping device is usually point contact or small area contact. As a result, the operator can usually only clamp one piece or a very small amount of broken foil each time using the clamping device, which makes the work efficiency of cleaning the broken foil extremely low and the labor intensity of the operator high. Summary of the Invention

[0003] In view of this, it is necessary to provide a cleaning device for broken foil in the formation tank to solve the technical problem that the operator can usually only clamp one piece or a very small amount of broken foil each time using the clamping device, which makes the efficiency of cleaning the broken foil extremely low and the labor intensity of the operator high.

[0004] The present invention provides a device for cleaning scrap foil in a forming tank, comprising a support rod and a scrap foil capture assembly. The scrap foil capture assembly is connected to the bottom end of the support rod and is supported by the support rod to extend into the forming tank. The scrap foil capture assembly attracts the surrounding scrap foil into the tank for collection and cleaning. The broken foil capture assembly includes a cleaning support box and a broken foil suction part. The front end of the cleaning support box has an opening, and several through holes are evenly provided on the rear side wall of the cleaning support box. There is at least one broken foil suction part, and the broken foil suction part is located at the rear end of the cleaning support box. The broken foil suction part is connected to the cleaning support box, and the bottom end of the support rod is connected to the upper side wall of the cleaning support box. The broken foil suction part disturbs the electrolyte, drives the electrolyte to flow into the cleaning support box from the front end opening of the cleaning support box and be discharged from the through hole of the rear side wall of the cleaning support box, so that the electrolyte around the cleaning support box flows in a directional manner to form a sweep flow converging toward the front end opening of the cleaning support box, and the sweep flow carries the broken foil into the cleaning support box for collection and cleaning.

[0005] It can be seen from the above technical solution that the present invention provides a cleaning device for broken foil in a formation tank, comprising a support rod and a broken foil capture assembly, the broken foil capture assembly comprising a cleaning support box and a broken foil suction unit, the front end of the cleaning support box having an opening, a plurality of through holes evenly provided on the rear side wall of the cleaning support box, at least one broken foil suction unit, the broken foil suction unit being located at the rear end of the cleaning support box, the broken foil suction unit being connected to the cleaning support box, the bottom end of the support rod being connected to the upper side wall of the cleaning support box, when using the cleaning device provided by the present application to clean broken foil in the formation tank, first, the operator can extend the broken foil capture assembly into the formation tank by holding the support rod, Then the scrap foil suction part disturbs the electrolyte, driving the electrolyte to flow into the cleaning support box from the front end opening of the cleaning support box and be discharged from the through hole on the rear side wall of the cleaning support box, so that the electrolyte around the cleaning support box will flow in a directional manner to form a sweep flow that converges toward the front end opening of the cleaning support box. The sweep flow carries the scrap foil into the cleaning support box. To this end, the operator only needs to adjust the position of the cleaning support box in the formation tank by holding the support rod to make the cleaning support box close to the scrap foil. The sweep flow can be used to actively carry a large amount of scrap foil into the cleaning support box for collection, thereby greatly improving the work efficiency of cleaning the scrap foil and reducing the labor intensity of the operator.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0023] Please see Figures 1 to 13 The present invention provides a device 10 for cleaning broken foil in a forming tank, comprising a support rod 110 and a broken foil capture assembly 120. The broken foil capture assembly 120 is connected to the bottom end of the support rod 110 and is supported by the support rod 110 to extend into the forming tank. The broken foil capture assembly 120 attracts the surrounding broken foil into the tank for collection and cleaning. The broken foil capture assembly 120 includes a cleaning support box 121 and a broken foil suction unit 122. The front end of the cleaning support box 121 has an opening, and a plurality of through holes 1211 are evenly provided on the rear side wall of the cleaning support box 121. There is at least one broken foil suction unit 122, which is located at the rear end of the cleaning support box 121. The broken foil suction unit 122 is connected to the cleaning support box 121, and the bottom end of the support rod 110 is connected to the upper side wall of the cleaning support box 121. The broken foil suction unit 122 disturbs the electrolyte, drives the electrolyte to flow from the front end opening of the cleaning support box 121 into the cleaning support box 121 and out of the cleaning support box The electrolyte is discharged through the through hole 1211 on the rear side wall of the cleaning support box 121, so that the electrolyte around the cleaning support box 121 will flow in a directional manner to form a sweep flow that converges to the front end opening of the cleaning support box 121. The sweep flow carries the broken foil into the cleaning support box 121 for collection and cleaning. At the same time, the diameter of the through hole 1211 can be tapered, and the diameter of the inlet end close to the inner side of the cleaning support box 121 is smaller than the diameter of the outer outlet end, so that the electrolyte can quickly flow into the cleaning support box 121 from the front end opening of the cleaning support box 121 and be discharged from the through hole 1211 on the rear side wall of the cleaning support box 121, thereby enhancing the sweep flow's entrainment force on the broken foil.

[0024] When using the cleaning device provided in the present application to clean the broken foil in the formation tank, the operator can first extend the broken foil capture assembly 120 into the formation tank by holding the support rod 110, and then the broken foil suction part 122 disturbs the electrolyte, driving the electrolyte to flow into the cleaning support box 121 from the front end opening of the cleaning support box 121 and be discharged from the through hole 1211 on the rear side wall of the cleaning support box 121, so that the electrolyte around the cleaning support box 121 flows in a directional manner to form a sweep flow converging toward the front end opening of the cleaning support box 121, and the sweep flow carries the broken foil into the cleaning support box 121. To this end, the operator only needs to adjust the position of the cleaning support box 121 in the formation tank by holding the support rod 110, so as to make the cleaning support box 121 close to the broken foil, and the sweep flow can be used to actively carry a large amount of broken foil into the cleaning support box 121 for collection, thereby greatly improving the work efficiency of cleaning the broken foil and reducing the labor intensity of the operator.

[0025] Furthermore, in order to prevent the broken foil from accumulating on the rear side wall of the cleaning support box 121 with the flow of the sweep flow and causing blockage of the through hole 1211, resulting in the reduction of the flow rate and flow of the sweep flow and the inability to effectively carry away the broken foil, a collection groove 1212 is provided on the upper side wall of the cleaning support box 121, and the collection groove 1212 is close to the rear end of the cleaning support box 121. The broken foil capture assembly 120 also includes a scraping and intercepting portion 123 and a collecting bin 124. The scraping and intercepting portion 123 is located in the cleaning support box 121, and the scraping and intercepting portion 123 is located below the collecting groove 1212. The collecting bin 124 is covered with a cover on the collecting bin 124. On the through groove 1212, the collecting bin 124 is fixedly connected to the upper side wall of the cleaning support box 121, and the scraping and intercepting portion 123 is rotatably connected to the cleaning support box 121. The sweep flow carries the broken foil into the cleaning support box 121 and impacts the scraping and intercepting portion 123 to rotate, so that the scraping and intercepting portion 123 captures the broken foil flowing into the cleaning support box 121 and centrifugally transports it to the collecting bin 124, thereby avoiding the broken foil flowing into the cleaning support box 121 from accumulating on the through hole 1211 and causing blockage, ensuring that the flow rate of the sweep flow is continuous and stable, and can effectively carry the broken foil into the cleaning support box 121.

[0026] In a preferred embodiment, the scraping and intercepting portion 123 includes a rotating roller 1231 and six scraping and guiding plates 1232. The six scraping and guiding plates 1232 all have a spiral inclination. The six scraping and guiding plates 1232 are evenly spaced on the outer peripheral surface of the rotating roller 1231, and each scraping and guiding plate 1232 extends along the axial direction of the rotating roller 1231. The six scraping and guiding plates 1232 are fixedly connected to the rotating roller 1231. The two ends of the rotating roller 1231 are respectively rotatably connected to the relative inner walls of the cleaning support box 121. The swept flow impacts the scraping and guiding plates 1232 to drive the rotating roller 1231 to rotate. At the same time, the scraping and guiding plates 1232 capture the broken foil flowing through. The captured broken foil is caused to pass through the collecting groove 1212 and enter the collecting bin 124 under the combined action of the centrifugal force generated by the rotation of the scraping and guiding plates 1232 and the spiral thrust generated by the spiral inclination.

[0027] In a preferred embodiment, a steel brush may be provided on the free end edge of the scraping guide plate 1232 to enhance the ability to intercept small broken foils.

[0028] In a preferred embodiment, in order to prevent the scraping foil from accumulating in the intersection area between the rear side wall and the bottom wall of the cleaning support box 121, resulting in the scraping guide plate 1232 being unable to scrape and the existence of a scraping dead corner, the intersection area between the rear inner wall and the bottom wall of the cleaning support box 121 is an arc-shaped scraping surface 1213. When the rotating roller 1231 drives the scraping guide plate 1232 to rotate, the free end edge of the scraping guide plate 1232 always maintains a constant small gap with the arc-shaped scraping surface 1213 on the motion trajectory, so that the scraping foil enters the collection bin 124 under the joint guidance of the scraping guide plate 1232 and the arc-shaped scraping surface 1213. This completely eliminates the cleaning dead corners and optimizes the conveying path of the scraping foil, thereby increasing the efficiency of the scraping foil entering the collection bin 124.

[0029] Furthermore, the shredded foil suction part 122 includes a guide cover 1221, a first drive motor 1222, and a first impeller 1223. The open end cover of the guide cover 1221 is arranged on the through hole 1211 of the rear side wall of the cleaning support box 121. The first drive motor 1222 and the first impeller 1223 are both located in the guide cover 1221, and the output end of the first drive motor 1222 is connected to the axis of the first impeller 1223. The guide cover 1221 and the rear side wall of the cleaning support box 121 are detachably connected by bolts. The first drive motor 1222 and the guide cover 1221 are detachably connected by bolts. The first drive motor 1222 drives the first impeller 1223 to rotate, so that the open end of the guide cover 1221 forms a negative pressure to drive the electrolyte in the cleaning support box 121 to be continuously discharged from the through hole 1211 to form a sweep flow.

[0030] In a preferred embodiment, in order to make the flow of the sweep flow uniform, a collecting bin 1214 is provided at the rear end of the cleaning support box 121, and the collecting bin 1214 is surrounded by the through hole 1211 on the rear side wall of the cleaning support box 121. There are five shredded foil suction parts 122, and the opening end of each guide cover 1221 is covered on the collecting bin 1214 to cover the entire area of ​​the through hole 1211, so that the guide cover 1221 and the collecting bin 1214 form a collecting space, and the first drive motor 1222 drives the first impeller 1223 to rotate, so that the collecting space surrounded by the guide cover 1221 and the collecting bin 1214 is The negative pressure formed in the space drives the electrolyte in the cleaning support box 121 to be continuously discharged from the through-hole 1211 to form a sweep flow. To this end, the five scrap foil suction parts 122 cooperate with the collecting bin 1214 to cover the entire area of ​​the through-hole 1211 to make the flow of the sweep flow uniform and stable. At the same time, by setting up five scrap foil suction parts 122, the cleaning device provided by the present application can also have a fault-tolerant mechanism. For example, when two scrap foil suction parts 122 are damaged and the remaining three scrap foil suction parts 122 are working normally, the cleaning device provided by the present application can still form a sweep flow to clean the scrap foil.

[0031] Furthermore, in order to clean the broken foil adhering to the bottom of the formation tank, the broken foil capture assembly 120 also includes a cleaning part 125. The cleaning part 125 is located on one side of the opening of the cleaning support box 121. The cleaning part 125 is connected to the cleaning support box 121. The cleaning part 125 rotates and scrapes to stir up the broken foil adhering to the bottom of the formation tank.

[0032] In a preferred embodiment, a strip-shaped placement slot 1215 is horizontally provided on the side wall of the opening of the cleaning support box 121, and the strip-shaped placement slot 1215 is close to the bottom wall of the cleaning support box 121. The cleaning part 125 includes a second drive motor 1251 and a second impeller 1252. The second drive motor 1251 is vertically located on one side of the opening of the cleaning support box 121, and the second drive motor 1251 is located above the strip-shaped placement slot 1215. The output end of the second drive motor 1251 is connected to the axis of the second impeller 1252. The cleaning support box 121 and the second drive motor 1251 are connected. The second impeller 1252 is fixedly connected so that the output end of the second drive motor 1251 supports the second impeller 1252 close to the bottom wall of the cleaning support box 121. During use, the operator can adjust the position of the cleaning support box 121 in the formation tank by holding the support rod 110, so that the cleaning support box 121 is close to the bottom of the formation tank. The second drive motor 1251 drives the second impeller 1252 to rotate and scrape through the long strip-shaped through groove 1215. The second impeller 1252 stirs up the broken foil adhered to the bottom of the formation tank and makes the broken foil converge to the opening of the cleaning support box 121, thereby effectively peeling off and collecting the broken foil adhered to the bottom of the tank.

[0033] In a preferred embodiment, in order to make the stirred-up foil scraps converge into the opening of the cleaning support box 121, thereby improving the capture rate of the foil scrap capture assembly 120 for the foil scraps, there are two cleaning parts 125, and the two cleaning parts 125 are respectively located on both sides of the opening of the cleaning support box 121. The two cleaning parts 125 have opposite rotation directions, so that the two cleaning parts 125 cooperate to form a convergent flow field, thereby directionally pushing and guiding the foil scraps to the opening area of ​​the cleaning support box 121, ensuring that the foil scraps can flow into the opening of the cleaning support box 121.

[0034] In a preferred embodiment, the lower end surface of the opening of the cleaning support box 121 has a guide slope, one end of the guide slope is connected to the lower inner wall of the opening of the cleaning support box 121, and the other end of the guide slope is connected to the lower surface of the opening of the cleaning support box 121, so that the guide slope is inclined in a direction that is conducive to the entry of the broken foil into the cleaning support box 121. Correspondingly, the cleaning part 125 is inclined above the guide slope, so that the second impeller 1252 of the two cleaning parts 125 can scrape the broken foil around the opening of the cleaning support box 121 into the cleaning support box 121 along the guide slope, thereby facilitating the entry of the broken foil into the cleaning support box 121 and preventing the broken foil from accumulating and staying at the opening of the cleaning support box 121.

[0035] In the present application, after the aluminum foil roll in the forming tank is retrieved and the related equipment is shut down to cut off the power to the forming tank, the operator can extend the broken foil capture assembly 120 into the forming tank by holding the support rod 110. The broken foil adhering to the bottom of the forming tank will first be stirred up by the two cleaning parts 125, and then the two cleaning parts 125 will cooperate to push the broken foil in a directional manner to the opening area of ​​the cleaning support box 121, thereby assisting the sweep flow generated by the broken foil suction part 122 to directly capture the broken foil in the area with a higher flow rate. Moreover, since the rotational pushing direction of the two cleaning parts 125 is consistent with the flow direction of the sweep flow, the two cleaning parts 125 can further drive and accelerate the flow rate of the sweep flow, enhance the entrainment and impact force of the sweep flow, and after the impact force of the sweep flow is enhanced, it can drive the rotating roller 1231 to rotate rapidly, so as to improve the capture efficiency of the scraping guide plate 1232 for the broken foil.

[0036] Taking into account the corrosive environment of the electrolyte in the formation tank, the cleaning support box 121, the deflector 1221, the first drive motor 1222, the first impeller 1223, the rotating roller 1231, the scraping guide plate 1232, the collecting bin 124, the second drive motor 1251 and the second impeller 1252 can all be made of stainless steel to prevent corrosion from the electrolyte, and the outside of the first drive motor 1222 and the second drive motor 1251 are both provided with sealed cabins to isolate the electrolyte and prevent the electrolyte from flowing into the interior of the first drive motor 1222 or the second drive motor 1251, causing erosion and damage.

[0037] Furthermore, the support rod 110 includes a telescopic sleeve 111 and a telescopic drive unit 112. The telescopic drive unit 112 passes through the telescopic sleeve 111. The telescopic drive unit 112 is connected to the telescopic sleeve 111. The bottom end of the telescopic sleeve 111 is connected to the upper side wall of the cleaning support box 121. The telescopic drive unit 112 drives the telescopic sleeve 111 to extend or shorten, and the telescopic sleeve 111 supports the cleaning support box 121 to extend into formation tanks of different depths.

[0038] Furthermore, the telescopic sleeve 111 includes a first sleeve 1111, a second sleeve 1112, and a third sleeve 1113.

The bottom end of the third sleeve 1113 is rotatably connected to the upper side wall of the cleaning support box 121. The telescopic driving unit 112 drives the second sleeve 1112 to telescope in the first sleeve 1111, and at the same time drives the third sleeve 1113 to telescope in the second sleeve 1112.
