Technical Field

[0001] The present application relates to the technical field of electroplating filtration, and in particular to a filtration circulation system for electroplating. Background Art

[0002] The traditional long-term system is difficult to achieve good circulation and filtration effects due to the immature technology, and the production of sardine nickel is unstable, and the long-term production cycle is greatly reduced. The traditional sardine nickel filtration circulation system is generally composed of a main tank, an overflow tank, a secondary tank, a long-term filter, and a pipeline. Its working process is that the main tank solution overflows to the secondary tank through the overflow tank, and the long-term filter circulates from the bottom of the secondary tank to the main tank outlet. At present, the pipeline setting of the electroplating filter connecting the management tank is unreasonable. With the accumulation of aging products in the production of sardine nickel, the filtration speed of the long-term filter slows down, the water flow rate decreases, and then the overflow speed of the main tank slows down, and the enrichment of the aging products in the main tank accelerates, which leads to a vicious cycle, resulting in deterioration of product quality and a limited long-term production cycle.

The overflow channels provided on the two side walls of the first reaction tank are connected to the first reaction zone through a pipeline. The liquid inlet end of the filtration device is connected to the first reaction zone. A part of the solution filtered by the filtration device flows back to the first reaction zone, and the other part flows back to the second reaction zone. The liquid inlet end of the long-term filtration device is connected to the second reaction zone.

[0014] The above-mentioned filtering circulation system for electroplating has at least the following beneficial effects: when in use, the tank liquid placed in the first reaction tank overflows and is transported to the first reaction zone of the second reaction tank through the overflow tank. The filtering device extracts and filters the tank liquid in the first reaction zone during the reaction, and the filtered solution is evenly divided and returned to the first reaction zone and the second reaction zone.

[0025] The traditional sardine nickel filtering circulation system consists of only a main tank, an overflow tank 101, a sub-tank, a long-acting filter 400, and a pipeline. Its working process is that the main tank medicine overflows to the sub-tank through the overflow tank 101, and the long-acting filter 400 takes in water from the bottom of the sub-tank and circulates to the main tank outlet. However, the long-acting filter 400 circulates to the main tank through a single-tube outlet, and currently all the pipes connecting the electroplating filter tank are connected by a single pipe. With the accumulation of aging products in the production of sardine nickel, the filtration speed of the long-acting filter 400 slows down, the water outlet flow rate decreases, and then the overflow speed of the main tank slows down, and the enrichment of the aging products in the main tank accelerates, forming a vicious cycle, resulting in deterioration of product quality and limited long-acting production cycle.

[0026] For this purpose, refer to Figure 1 and Figure 2 The embodiment of the present application provides an optimized filtering circulation system for electroplating, which specifically includes a first reaction tank 100, a second reaction tank 200, a filtering device 300 and a long-term filtering device 300. The liquid outlet of the long-term filtering device 300 is connected to the first reaction tank 100. A solution dispensing member is provided in the first reaction tank 100, and the solution dispensing member is provided with a plurality of liquid outlet holes 111. The second reaction tank 200 is provided with adjacent first reaction areas 210 and second reaction areas 220. The overflow channels provided on the two side walls of the first reaction tank 100 are connected to the first reaction area 210 through a pipeline. The liquid inlet of the filtering device 300 is connected to the first reaction area 210. A part of the solution filtered by the filtering device 300 flows back to the first reaction area 210, and the other part flows back to the second reaction area 220. The liquid inlet of the long-term filtering device 300 is connected to the second reaction area 220.

[0027] The filtering circulation system for electroplating of the present application optimizes the water inlet method of the first reaction tank 100 to improve the efficiency and quality of the circulating filtration. At the same time, by adding a filtering device 300 in conjunction with the optimized second reaction tank 200, it can reduce the situation where aging foreign matter enters the long-term filter 400 to affect the filtration efficiency and blockage.

[0028] Specifically, when in use, the tank liquid placed in the first reaction tank 100 overflows and is transported to the first reaction zone 210 of the second reaction tank 200 through the overflow tank 101. The filtering device 300 extracts and filters the tank liquid of the first reaction zone 210 during the reaction, and the filtered solution is evenly divided and returned to the first reaction zone 210 and the second reaction zone 220. As the reaction proceeds gradually, the water in the second reaction zone 220 will slowly overflow to the first reaction zone 210 to ensure that the solution in the first reaction zone 210 and the second reaction zone 220 is balanced. Since the filtering device 300 continuously extracts the first reaction zone 210, although there is also filtered water in the first reaction zone 210, the tank liquid in the first reaction zone 210 is always in a state of being ... In the case where the solution does not overflow into the second reaction zone 220, the unfiltered solution of the first reaction zone 210 can also be prevented from overflowing into the second reaction zone 220. After the solution filtered by the filter device 300 enters the first reaction zone 210, the solution in the first reaction zone can be further stirred, so that the aged foreign matter deposited at the bottom can be stirred evenly, which is convenient for transporting to the filter device 300 for filtration. At the same time, the filtration effect can be further improved, so that the tank liquid can complete the preliminary filtration before entering the long-term filter 400, thereby reducing the burden on the long-term filter 400, avoiding the situation where the deposition of aged foreign matter in the pipeline affects the solution transmission efficiency, improving the efficiency of the circulation filtration, and extending the service life of the long-term filter 400.

[0029] At the same time, the long-term filter 400 extracts the tank liquid after preliminary filtration from the second reaction zone 220 for final filtration. The tank liquid filtered by the long-term filter 400 flows back to the first reaction tank 100, thus realizing a complete filtration cycle. Furthermore, the water filtered by the long-term filter 400 is distributed to various parts of the first reaction tank 100 through the solution distribution component, and the setting of the liquid outlet 111 enables the filtered solution entering the first reaction tank 100 to stir the solutions in various parts of the first reaction tank 100, thereby promoting the tank liquid of the first reaction tank 100 to be in a uniformly mixed state at all times, avoiding the added reaction components from being deposited on the bottom of the first reaction tank 100, and successfully solving the problem of product discoloration caused by uneven tank liquid. At the same time, the tank liquid is continuously stirred, and the aging products are timely passed through the overflow port to the auxiliary tank, and are timely filtered and processed by the filtering device 300, thereby reducing the aging product content in the first reaction tank 100, so that when the first reaction tank 100 is subjected to electroplating reaction, the bright spots of the product are fundamentally improved.

[0030] Compared with the prior art, the present application improves the water inlet method of the first reaction tank 100, utilizes the incoming water to stir the tank liquid, and then re-optimizes the second reaction tank 200, and cooperates with the filtering device 300 to achieve preliminary filtration of the aging products produced by the electroplating reaction, thereby effectively improving the filtration effect of the tank liquid, overcoming and improving the bright spot problem, stabilizing the quality of the electroplating products, achieving long-term and ultra-long cycle production, improving the effective operation of the entire production line, saving material loss and waste, and reducing the intensity of employees changing targets.

[0031] In some embodiments, Figure 1 and Figure 2 As shown, the solution dispensing member is connected to the liquid outlet of the long-term filtering device 300 through a conduit, and the solution dispensing member extends from one end of the first reaction tank 100 to the other end, and the distance between the solution dispensing member and the bottom of the first reaction tank 100 is less than one tenth of the depth of the first reaction tank 100. The solution dispensing member is arranged close to the bottom of the first reaction tank 100, and combined with the liquid outlet 111, it can effectively promote the uniform mixing of the tank liquid in the first reaction tank 100, and smoothly solve the problem of product discoloration caused by uneven tank liquid. At the same time, because the tank liquid is continuously stirred by the solution sprayed from the liquid outlet 111 during the circulation process, the aging product is no longer deposited and can be timely filtered through the overflow port to the second reaction tank 200, and then filtered in time by the filtering device 300, and the bright spots of the product are fundamentally improved.

[0032] like Figure 3 and Figure 4As shown, the liquid outlet holes 111 are arranged at intervals, and the opening direction of the liquid outlet holes 111 is toward the bottom of the first reaction tank 100. Setting the opening direction of the liquid outlet holes 111 toward the bottom of the first reaction tank 100 can make the solution sprayed by the liquid outlet holes 111 stir the aged foreign matter deposited on the bottom, ensuring that the aged foreign matter can be timely transported to the second reaction tank 200 through the overflow tank 101 for effective filtration during circulation filtration.

[0033] In the embodiment of the present application, the solution dispensing member includes two dispensing tubes 110 disposed at intervals, and a liquid outlet 111 is disposed at intervals between the two ends of the dispensing tube 110. Figures 2 to 4 As shown, the solution dispensing member includes two dispensing tubes 110 arranged side by side, and the two ends of the dispensing tube 110 are respectively close to the two ends of the first reaction tank 100, and then the liquid outlet holes 111 are arranged at intervals between the two ends of the dispensing tube 110, so that the aged foreign matter deposited at the bottom of the first reaction tank 100 can be effectively and comprehensively stirred and mixed.

[0034] In some examples, two adjacent liquid outlets 111 on the distribution tube 110 are respectively located on both sides of the distribution tube 110, and in actual use, the liquid outlets 111 are mainly distributed on both sides of the lower part of the distribution tube 110. The angle between the central axis of the liquid outlet 111 and the bottom of the tank is set to 30° to 60°. Compared with the vertically arranged liquid outlets 111 at the bottom of the tank, combined with the evenly spaced distribution, when the long-term filter 400 is started, the tank liquid is discharged obliquely downward from the distribution pipe, so that the tank liquid is continuously stirred and raised from the bottom of the tank, promoting the uniform mixing of the tank liquid in the first reaction tank 100, and smoothly solving the problem of product discoloration caused by uneven tank liquid. At the same time, the tank liquid is continuously stirred, and the aging product is timely passed through the overflow port to the second reaction tank 200, and filtered and processed in time, and the bright spots of the product are fundamentally improved.

[0035] In the embodiment of the present application, both ends of the two dispensing pipes 110 can be connected to each other to form a zigzag structure, and the angle between the central axis of the liquid outlet 111 and the bottom of the groove is set to 45°.

[0036] In some examples, the diameter of the liquid outlet hole 111 is set to 2-8 mm, and the spacing between two adjacent liquid outlet holes 111 is set to 30-80 mm. In this embodiment, the diameter of the liquid outlet hole 111 is set to 3.2 mm, the spacing between two adjacent liquid outlet holes 111 is set to 50 mm, and the diameter of the distribution tube 110 is set to 32 mm.

[0037] The inner dimensions of the first reaction tank 100 are 2400 mm in length, 1200 mm in width, and 1500 mm in height. There are 100 mm overflow grooves 101 on both sides of the tank wall near the top.

[0038] The filter device 300 is a double-barrel filter pump specially used for pumping carbon powder. The filter device 300 includes a liquid inlet pipe 310 connected to the first reaction zone 210 and two liquid outlet pipes 320, and the two liquid outlet pipes 320 are respectively connected to the bottom of the first reaction zone 210 and the bottom of the second reaction zone 220. The liquid inlet of the liquid inlet pipe 310 and the liquid outlet of the liquid outlet pipe 320 of the first reaction zone 210 should be staggered.

[0039] The inner dimensions of the second reaction tank 200 are 1000 mm in length, 800 mm in width, and 1500 mm in height.

[0040] A first partition 201 is disposed in the second reaction tank 200 to divide the internal space of the second reaction tank 200 into a first reaction zone 210 and a second reaction zone 220. The first partition 201 is provided with an arc near the top of the second reaction tank 200 to facilitate the overflow solution to flow back to the first reaction zone 210 for continued filtration. The first partition 201 is made of PP material.

[0041] In some embodiments, an overflow area 230 is enclosed at the bottom of the second reaction zone 220 through the second partition 202, and the liquid inlet end of the long-term filter device 300 is connected to the overflow area 230 through a conduit. Specifically, the second partition 202 and the two adjacent side walls of the second reaction zone 220 enclose an overflow area 230 of the same number as the merchant, and the solution filtered by the filter device 300 does not first enter the overflow area 230. When the solution in the second reaction zone 220 is so much that it overflows to the overflow area 230, the long-term filter 400 can extract the circulated solution. The setting of the overflow area 230 allows the solution entering the first reaction zone 210 to further precipitate, which can reduce the aging foreign matter that is not fully filtered by the filter device 300 from entering the long-term filter 400.

[0042] Specifically, the height of the second partition plate 202 is less than one fifth of the height of the second reaction tank 200 , and the second partition plate 202 should not be set too high.

[0043] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
