Description

Technical Field

[0002] Electroplating is a common surface treatment process that deposits a layer of metal or alloy on the metal surface to enhance the performance and appearance of the object. Some of the chemicals used in the electroplating process may be toxic, and appropriate wastewater treatment and safety measures need to be taken to reduce the impact on the environment.

[0003] Wastewater generated by electroplating is generally stored using a collection device, and chemical agents are added to separate the impurities in the wastewater from the water, and then the impurities in the wastewater are removed.

[0004] By searching the Chinese patent application number: 202220345633.6, a waste liquid collection device for electroplating treatment is found, including a tank body, a tank cover, a feeding bin, a liquid inlet pipe, a liquid outlet pipe, an inner tank, a transfer pipe, a solenoid valve, a stirring assembly and a separation assembly. The separation assembly includes a propeller, a conveying pipe and a conveying member. The conveying pipe is fixedly connected to the tank body and detachably connected to the transfer pipe. This technical solution has solved the problem that some of the existing collection devices cannot completely remove fixed impurities from the liquid storage bin, resulting in poor solid-liquid separation. However, the impurities in the wastewater vary in size, and the filter hole diameter in this technical solution remains unchanged, so it cannot filter impurities of different sizes well. This will cause smaller impurities to flow into the liquid, requiring further impurity removal treatment, which is inefficient to use.

[0027] This specific embodiment is a waste liquid collection device for electroplating treatment that is easy to remove impurities. Its structural diagram is as follows Figures 1-8As shown, it includes a shell 1, a number of circular plates 2 are arranged in the shell 1, the circular plates 2 are fixedly connected to the inner wall of the shell 1, the top of the circular plate 2 is provided with evenly distributed filter holes 3, and a discharge mechanism is provided above the filter holes 3. The bottom of the shell 1 is fixedly connected with evenly distributed support legs 15, a drain pipe 16 is installed at the bottom of the shell 1, and a water valve 17 is installed on the drain pipe 16. The top of the shell 1 is fixedly connected with an evenly distributed fixed plate 18, a hopper 19 is provided above the shell 1, and the top of the fixed plate 18 is fixedly connected to the hopper 19. A flow control valve 20 is installed on the outer wall of the hopper 19 near the bottom, and a connecting rod 21 is installed on the flow control valve 20. The outer wall of the shell 1 is provided with a discharge opening 8 matching the circular plate 2, and the outer wall of the shell 1 is provided with a debris collection mechanism.

[0028] The pore sizes of the filter holes 3 are different, and the pore sizes of the filter holes 3 gradually decrease from top to bottom, so that the wastewater can be filtered in multiple stages and debris of different sizes can be intercepted. The flow valve 20 in this technical solution is a common flow control valve on the market. Its working principle is common knowledge and relatively mature, so it is not described in detail in this technical solution.

[0029] like Figure 3-Figure 6 As shown, the discharge mechanism packs a mounting plate 6, and several mounting plates 6 are provided and are respectively located above the circular plate 2. The top of the mounting plate 6 is conical, and evenly distributed arc-shaped push plates 7 are fixedly connected to the side walls of the mounting plate 6. The bottom of the inner cavity of the shell 1 is movably connected to the transmission rod 4 through a bearing. The top of the transmission rod 4 passes through the circular plate 2 and the mounting plate 6 and is movably connected to the circular plate 2. A scraping mechanism is provided on the side wall of the transmission rod 4, and the scraping mechanism is located below the circular plate 2. A motor 5 is installed at the bottom of the shell 1, and the bottom end of the transmission rod 4 passes through the inner ring of the bearing and is rotatably connected to the output end of the motor 5.

[0030] The intercepted debris can be discharged out of the shell 1 through the discharge mechanism. When the arc-shaped push plate 7 rotates counterclockwise, it can push the debris at any position on the circular plate 2 outward. At the same time, it can clean the top of the circular plate 2 to prevent the debris from sticking to the circular plate 2, thereby effectively improving the use efficiency.

[0031] like Figure 1 and Figure 7 As shown, the debris collection mechanism includes a placement plate 11, and several placement plates 11 are provided and fixedly connected to the outer wall of the shell 1. The placement plate 11 is L-shaped, and a material receiving box 10 is provided in the placement plate 11. The inner wall of the material receiving box 10 is fixedly connected to a filter plate 12, and the outer wall of one side of the material receiving box 10 is fixedly connected to a round tube 13. The round tube 13 is connected to the inside of the material receiving box 10, and the front and rear side walls of the material receiving box 10 are respectively fixedly connected to handles 14. The outer wall of the shell 1 is fixedly connected to a material guide plate 9, and several material guide plates 9 are provided. The material guide plate 9 is located above the material receiving box 10, and the material guide plate 9 is U-shaped.

[0032] The receiving box 10 can store the discharged debris, drain the waste water from the debris, and discharge the drain water. The receiving box 10 can be separated from the shell 1 and can be easily removed and placed. In addition, the outer wall of the receiving box 10 fits the outer wall of the shell 1.

[0033] like Figure 3 and Figure 6 As shown, the scraping mechanism includes a scraping rod 22 , and a plurality of scraping rods 22 are provided. One end of the scraping rod 22 is fixedly connected to the transmission rod 4 , and the top of the scraping rod 22 contacts the bottom of the circular plate 2 .

[0034] The scraping mechanism can scrape the bottom of the circular plate 2, which can prevent wastewater from remaining at the bottom of the circular plate 2 and accumulating, and can prevent the filter holes 3 from being blocked to a certain extent, thereby improving the stability of use.

[0035] Working principle: When using this technical solution, first place the waste liquid collection device where it is needed, and install and debug it. After the preparation is completed, connect the water pipes to the two circular pipes 13, and then discharge the waste water into the receiving hopper 19. Control the flow control valve 20 through the connecting rod 21 to open the bottom of the receiving hopper 19, and control the water flow not to be too large, so that when the waste water flows into the circular plate 2, it will not flow into the receiving box 10 through the discharge opening 8 because the filtration cannot keep up with the speed of the waste water flow. When the waste water in the receiving hopper 19 falls on the upper circular plate 2 and is filtered for the first time through the filter holes 3, the larger impurities in the waste water will be intercepted on the upper circular plate 2. After the first filtration, the waste water reaches the lower circular plate 2 and is filtered again by the filter holes 3 on the lower circular plate 2, so that smaller impurities in the waste water can be intercepted on the lower circular plate 2, and finally the filtered waste water enters the bottom of the inner cavity of the shell 1 for storage. When the receiving hopper 1 After the wastewater in 9 is filtered, the motor 5 is started by an external power supply to drive the transmission rod 4 to rotate counterclockwise, and the transmission rod 4 drives the mounting plate 6 and the arc push plate 7 to rotate counterclockwise synchronously. When the arc push plate 7 rotates, it can gradually push the debris intercepted on the circular plate 2 outward through the arc setting, so that the debris will be discharged from the shell 1 through the discharge opening 8, and then discharged into the receiving box 10 through the guide plate 9 and fall onto the filter plate 12. When the transmission rod 4 rotates, it can drive the scraper rod 22 to rotate to scrape the bottom of the circular plate 2, which can effectively clean the debris and water droplets at the bottom of the circular plate 2 to avoid the bottom of the circular plate 2 being stuck with debris after long-term use. If there is wastewater on the discharged debris, it can be left on the filter plate 12 to drain the debris. After the discharge is completed, the motor 5 is turned off, and then the water valve 17 can be opened to discharge the filtered wastewater in the shell 1, and the receiving box 10 can be removed for the next step of treatment of the debris. The above operation can effectively filter the wastewater multiple times and discharge the debris.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
