Description

Technical Field

[0001] This utility model relates to the field of electrophoresis tank technology, and in particular to an overflow recovery device for electrophoresis tanks. Background Technology

[0002] During the electrophoretic coating process, paint or cleaning solution in the electrophoresis tank often overflows due to factors such as liquid level fluctuations and workpiece replacement. To achieve resource recovery and environmental protection, a specialized overflow recovery device is needed to collect, filter, and reuse the overflow liquid. This type of device is a key piece of equipment in the electrophoretic production line to reduce material waste and lower wastewater treatment costs, and its structural rationality directly affects recovery efficiency and ease of operation.

[0003] Existing electrophoresis tank overflow recovery devices typically include an overflow receiving structure installed on the outer wall of the electrophoresis tank, such as an overflow weir or recovery tank fixed to the edge of the tank. The overflow water flows into a collection container by gravity. The collection container is usually connected to the recovery structure by bolts, clips, or other fixing methods. Some devices also have valves or filters installed in the liquid delivery path to achieve preliminary filtration and flow control.

[0004] However, in existing technologies, the connection structure between the collection tank, as the core liquid storage component, and the main body of the recycling device is complex. Disassembly, maintenance, or replacement often requires the use of multiple tools such as wrenches and screwdrivers to remove the fasteners one by one, resulting in cumbersome procedures that not only consume a lot of time but also disrupt the normal operation of the production line. Therefore, an electrophoresis tank overflow recycling device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an overflow recovery device for an electrophoresis tank, which aims to improve the problem that the collection box in the prior art requires multiple tools to be used and cannot be easily disassembled.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An overflow recovery device for an electrophoresis tank includes an electrophoresis tank with multiple overflow ports inside. A placement plate is fixedly connected to the outer wall of the electrophoresis tank, and a collection box is slidably connected inside the placement plate. A disassembly assembly is provided on the outer wall of the placement plate, and a discharge pipe is fixedly connected to the bottom of the collection box. A limiting assembly is provided inside the discharge pipe.

[0008] The assembly / disassembly assembly includes a pin, the outer wall of which is slidably connected to the inside of the placement plate. A fixed outer shell is fixedly connected to the outer wall of the placement plate. A pull rod is rotatably connected to the outer wall of the pin. A limiting ring is fixedly connected to the outer wall of the pin. The outer wall of the limiting ring is slidably connected to the inside of the fixed outer shell. A spring is sleeved on the outer wall of the pin. One end of the spring is fixedly connected to the outer wall of the limiting ring, and the other end of the spring is fixedly connected to the inner wall of the fixed outer shell.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a sealing plug, the outer wall of which is slidably connected inside the discharge pipe.

[0011] As a further description of the above technical solution:

[0012] The discharge pipe has an outlet, and the outer wall of the sealing plug is slidably connected to the inside of the outlet.

[0013] As a further description of the above technical solution:

[0014] A connecting plate is fixedly connected to the inner wall of the discharge pipe, and a connecting shell is fixedly connected to the other side of the connecting plate.

[0015] As a further description of the above technical solution:

[0016] The bottom of the sealing plug is fixedly connected to a transmission column, and the outer wall of the transmission column is slidably connected inside the connecting housing.

[0017] As a further description of the above technical solution:

[0018] The connecting housing has a transmission groove inside, and a transmission disc is fixedly connected to the bottom of the transmission column. The outer wall of the transmission disc is slidably connected inside the transmission groove.

[0019] As a further description of the above technical solution:

[0020] A second spring is provided inside the connecting housing. The top of the second spring is fixedly connected to the bottom of the transmission disc, and the bottom of the second spring is fixedly connected to the inner wall of the transmission groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the pin moves by pulling the lever. When the lever is pulled, the lever drives the pin and the limiting ring, and in conjunction with the spring, the pin slides inside the placement plate, thus facilitating the disassembly and assembly of the collection box. This makes it convenient for maintenance, replacement, and movement, and solves the problem that multiple tools are needed to disassemble the collection box, which makes disassembly inconvenient. This improves the convenience of disassembling and assembling the collection box.

[0023] 2. In this utility model, the sealing plug achieves its movement function through overflow recovery. When recovery is carried out, the overflow drives the transmission column and transmission ring and cooperates with the second spring to realize the sliding of the sealing plug inside the discharge port, thereby limiting the flow of the recovered liquid, avoiding backflow, solving the problem of not being able to directly guide the recovered liquid, and improving the safety of recovery.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of an electrophoresis tank overflow recovery device, including an electrophoresis tank 1. The electrophoresis tank 1 has multiple overflow ports 2 inside. The overflow ports 2 are rectangular notches, which are used to guide the overflowing liquid into the recovery system when the liquid level in the electrophoresis tank 1 exceeds a set height, so as to avoid the liquid from leaking and polluting the environment. A placement plate 5 is fixedly connected to the outer wall of the electrophoresis tank 1. The placement plate 5 is a horizontal bearing structure cut from Q235 steel plate, which is used to provide stable support for the collection box 3. The collection box 3 is slidably connected inside the placement plate 5. The collection box 3 is an open box structure made of PP material, which is used to receive the liquid flowing out from the overflow ports 2. The outer wall of the placement plate 5 is provided with a disassembly and assembly component. The bottom of the collection box 3 is fixedly connected with a discharge pipe 4, and a limiting component is provided inside the discharge pipe 4.

[0033] The assembly and disassembly components include a pin 10, the outer wall of which is slidably connected to the inside of the placement plate 5. The outer wall of the placement plate 5 is fixedly connected to a fixed housing 6. The outer wall of the pin 10 is rotatably connected to a pull rod 7. The outer wall of the pin 10 is fixedly connected to a limiting ring 9. The outer wall of the limiting ring 9 is slidably connected to the inside of the fixed housing 6. A spring 8 is sleeved on the outer wall of the pin 10. One end of the spring 8 is fixedly connected to the outer wall of the limiting ring 9, and the other end of the spring 8 is fixedly connected to the inner wall of the fixed housing 6. The pin 10 moves in conjunction with the spring 8 to achieve the effect of quickly fixing or releasing the collection box 3.

[0034] Reference Figure 1 , Figure 4 and Figure 5The limiting component includes a sealing plug 12, which is a stepped sealing structure molded from nitrile rubber. Its outer wall precisely fits the inner wall of the discharge pipe 4. The outer wall of the sealing plug 12 is slidably connected to the inside of the discharge pipe 4. The discharge pipe 4 has an outlet 13, which is a tapered through-hole structure for liquid flow. The outer wall of the sealing plug 12 is slidably connected to the inside of the outlet 13, achieving a seal through tight fit. A connecting plate 11 is fixedly connected to the inner wall of the discharge pipe 4, and a connecting shell 15 is fixedly connected to the other side of the connecting plate 11. The hollow cylindrical structure, made of seamless stainless steel tube, is used to house the transmission components. The bottom of the sealing plug 12 is fixedly connected to the transmission column 14. The outer wall of the transmission column 14 is slidably connected to the inside of the connecting shell 15. The connecting shell 15 has a transmission groove 18 inside. The transmission groove 18 is a cylindrical cavity structure that provides space for component movement. The bottom of the transmission column 14 is fixedly connected to the transmission disc 17. The outer wall of the transmission disc 17 is slidably connected to the inside of the transmission groove 18. The connecting shell 15 has a second spring 16 inside. The top of the second spring 16 is fixedly connected to the bottom of the transmission disc 17, and the bottom of the second spring 16 is fixedly connected to the inner wall of the transmission groove 18.

[0035] Working principle: When the collection box 3 needs maintenance and replacement after long-term use, the operator can directly pull the lever 7. The traction force of the lever 7 will drive the pin 10 to move horizontally, so that the pin 10 will gradually slide out of the positioning hole at the bottom of the collection box 3. During this process, the pin 10 will simultaneously drive the limiting ring 9 fixed on its surface to move into the fixed shell 6. The limiting ring 9 will squeeze the spring 8 inside the fixed shell 6, so that the spring 8 is in a compressed state, storing elastic potential energy for subsequent reset. At this time, the fixed relationship between the collection box 3 and the placement plate 5 is released, and the operator can easily remove the collection box 3 from the top of the placement plate 5 for cleaning or replacement. After maintenance is completed, the collection box 3 is put back in its original position on the top of the placement plate 5, the lever 7 is released, the compressed spring 8 releases its elastic force, and pushes the limiting ring 9 and the pin 10 to move in the opposite direction, so that the pin 10 slides back into the positioning hole of the collection box 3, completing the stable fixation of the collection box 3. The whole process does not require tools and is efficient and convenient to operate.

[0036] In addition, during the overflow recovery operation of the electrophoresis tank, when the recovered liquid enters the outlet 13 through the collection structure, the impact force of the liquid will push the sealing plug 12 to slide axially inside the outlet 13. When the sealing plug 12 moves, it drives the transmission column 14 connected to it to move synchronously. The transmission disc 17 connected to the other end of the transmission column 14 slides in the transmission groove 18, compressing the spring 16 in the transmission groove 18 to store energy. At this time, the sealing plug 12 is disengaged from the sealing position of the outlet 13, and the liquid flows smoothly out of the outlet 13 into the subsequent recovery pipeline. When the overflow recovery is completed and the liquid pressure disappears, the compressed spring 16 releases its elastic potential energy, pushing the transmission disc 17 back to the initial position in the transmission groove 18. The transmission column 14 then drives the sealing plug 12 to slide back into the outlet 13, tightly fitting to achieve a seal, effectively blocking the liquid backflow path and ensuring the one-way flow of the recovery system.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
