Description

Technical Field

[0001] This utility model relates to the field of oil removal equipment technology, specifically to an electrophoresis pretreatment device. Background Technology

[0002] Degreasing is an indispensable step in the electrophoretic coating process. It mainly refers to the removal of oil from the surface of workpieces that have stamping oil, rolling oil, rust-preventive oil, and a small amount of dirt. If these oil stains are not cleaned properly, they can easily affect the quality of the electrophoretic coating. After treatment, grease and other impurities will float on the surface of the water tank, and it is difficult to remove them manually. This not only affects the efficiency of the production line, but may also release irritating odors during the degreasing process, causing environmental pollution.

[0003] Chinese patent provides a metal pre-electrophoresis degreasing device, publication number CN218710871U, which includes a degreasing tank, an degreasing chamber is provided in the middle of the degreasing tank, two sets of overflow chambers are symmetrically arranged on the left and right sides of the degreasing chamber, a drain valve is provided at the bottom of the side wall of the degreasing chamber and the overflow chamber, and a water inlet valve is also provided at the bottom of the side wall of the degreasing chamber.

[0004] The above-mentioned device can process multiple metal pieces at once through the placement box. The transport mechanism facilitates the horizontal and vertical adjustment of the placement box, making it more flexible in use. The front drive gears drive the placement box to rotate, which can make the metal inside the placement box turn over at a uniform speed, so that the metal comes into full contact with the cleaning fluid and accelerates the removal of oil stains from the metal. The oil driving mechanism and overflow channel can accelerate the overflow of oil stains floating on the surface of the cleaning fluid, avoiding contamination of the cleaned metal.

[0005] However, its degreasing structure is relatively simple. During the degreasing process, the cleaning fluid needs to be completely drained and refilled into the degreasing tank multiple times, resulting in poor continuous cleaning effect and affecting cleaning efficiency. Furthermore, multiple parts need to work together to transfer the grease during cleaning, which involves many moving parts, making replacement difficult after damage. Additionally, the degreasing process via the spray plate requires multiple adjustments, resulting in low degreasing efficiency. Utility Model Content

[0006] The purpose of this invention is to provide an electrophoresis pretreatment device that can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An electrophoresis pretreatment device includes an oil removal and cleaning tank, a circulation tank is provided at the rear end of the oil removal and cleaning tank, an overflow baffle is provided at the connection between the oil removal and cleaning tank and the circulation tank, an overflow port is provided at the upper position of the front and rear ends of the overflow baffle 3, and an overflow guide box 4 is provided at the end of the overflow port near the circulation tank 2.

[0009] A circulating water pump is installed at the center of the bottom of the circulation tank, and the pump's suction port is connected to the drain port at the bottom of the circulation tank. A circulating water outlet is located at the lower front end of the overflow baffle, and the inlet of the outlet is connected to the pump's drain pipe. A guide plate matching the circulating water outlet is installed on the bottom wall of the oil removal and cleaning tank.

[0013] Preferably, a measuring tube is fixedly installed at one side of both the front and rear ends of the overflow baffle, and a liquid inlet is provided at the bottom end of the measuring tube, and a water level detector is installed at the top end of the measuring tube.

[0014] Preferably, electric slide rails are installed on the upper sides of the oil removal and cleaning tank and the circulation tank, and a drain valve pipe is installed on the lower side of the circulation tank and the oil removal and cleaning tank away from the measuring tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up an oil removal cleaning tank, a circulation tank, a circulating water pump, an overflow guide box, and an overflow baffle to work together, facilitates the extraction of grease-free cleaning liquid from the bottom of the circulation tank during cleaning. At the same time, it can promote the floating grease in the oil removal cleaning tank to flow towards the overflow guide box, so as to continuously push the grease cleaned by the oil removal cleaning tank into the circulation tank, avoid the workpiece being secondary contaminated by grease during the oil removal process, and improve the cleaning effect.

[0017] By coordinating the water level detector, water supply pipe, and water inlet, the cleaning fluid can be replenished or replaced as needed during the degreasing process. The degreasing process does not require all the cleaning fluid to be extracted, which reduces the time for secondary fluid replenishment, allowing for continuous cleaning and improving processing efficiency. Furthermore, the degreasing process does not require adjusting multiple moving parts back and forth to scrape oil, reducing maintenance difficulty. Attached Figure Description

Detailed Implementation

[0022] 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. Example 1

[0023] Combination Figures 1-3 An electrophoresis pretreatment device includes an oil removal and cleaning tank 1, a circulation tank 2 is provided at the rear end of the oil removal and cleaning tank 1, an overflow baffle 3 is provided at the connection between the oil removal and cleaning tank 1 and the circulation tank 2, an overflow port is provided at the upper position of the front and rear ends of the overflow baffle 3, and an overflow guide box 4 is provided at the end of the overflow port near the circulation tank 2.

[0024] See Figure 2 and Figure 3Furthermore, a circulating water pump 5 is installed at the center of the bottom of the circulation tank 2, and the suction port of the circulating water pump 5 is connected to the discharge port at the bottom of the circulation tank 2. A circulating water outlet 6 is provided at the lower front end of the overflow baffle 3, and the inlet of the circulating water outlet 6 is connected to the discharge pipe of the circulating water pump 5. A guide plate 7 is provided on the bottom wall of the oil removal cleaning tank 1, which is compatible with the circulating water outlet 6. A water inlet 8 is installed at the upper front end of the oil removal cleaning tank 1, and a water inlet pipe 9 is connected to the front end of the water inlet 8. The guide plate 7 is inclined, and the end away from the circulating water outlet 6 is raised. The bottom end of the water inlet 8 is inclined, and the inclination angle is compatible with the guide plate 7. Electric slide rails 16 are installed at the upper sides of the oil removal cleaning tank 1 and the circulation tank 2. A drain valve pipe 15 is provided at the lower side of the circulation tank 2 and the oil removal cleaning tank 1 away from the measuring pipe 11.

[0025] Specifically, according to existing technology, the degreasing support frame can be installed at the electric slide rail 16 so that the workpiece to be degreased can be placed into the degreasing cleaning tank 1. After the workpiece is placed in and the cleaning fluid is added to a suitable height, the liquid level inside the circulation tank 2 is kept lower than the bottom of the overflow guide box 4, and the cleaning fluid level inside the degreasing cleaning tank 1 is matched with the overflow port to facilitate liquid circulation. Subsequently, the circulating water pump 5 can be started. Since the inlet of the circulating water pump 5 is installed below the circulation tank 2 and the outlet of the circulating water pump 5 is connected to the circulation outlet 6, the grease-free cleaning fluid at the bottom of the circulation tank 2 can be drawn out by the circulating water pump 5 and sent back to the circulation outlet 6 for spraying. Because the liquid level inside the circulation tank 2 is lower than the overflow guide box 4, The overflow guide box 4 forms a downward water flow at one end facing the circulation tank 2. At this time, the water flow sprayed from the circulation outlet 6 will be guided by the guide plate 7 and the water inlet 8, and flow towards the overflow outlet and out through the overflow guide box 4. During the flow, the grease floating on the surface of the cleaning liquid in the degreasing cleaning tank 1 can be made to flow towards the overflow guide box 4, so as to push the grease in the degreasing cleaning tank 1 to the circulation tank 2. After the grease and cleaning liquid enter the circulation tank 2, the lighter grease floats on the surface of the cleaning liquid in the circulation tank 2, while the heavier cleaning solution is at the bottom. The above steps are repeated to continuously push the grease cleaned by the degreasing cleaning tank 1 into the circulation tank 2, so as to avoid the workpiece being contaminated by grease again during the degreasing process. Example 2

[0026] See Figure 2Furthermore, based on Embodiment 1, an oil removal baffle 13 is fixedly installed at the rear of the interior of the circulation tank 2. An oil drain pipe 14 is connected to the front of the bottom of the circulation tank 2. An oil drain solenoid valve is provided at the connection between the oil drain pipe 14 and the circulation tank 2. The top surface of the oil removal baffle 13 is lower than the bottom surface of the overflow guide box 4. An impurity filter screen 10 is snapped into the rear end of the overflow guide box 4. A handle is provided at the center of the top of the impurity filter screen 10. Measuring tubes 11 are fixedly installed on one side of both the front and rear ends of the overflow baffle 3. An inlet is provided at the bottom of the measuring tube 11. A water level detector 12 is installed through the top of the measuring tube 11.

[0027] Specifically, during application, the cleaning liquid level in the circulation tank 2 should be lower than the bottom surface of the overflow guide box 4 and higher than the top surface of the degreasing baffle 13. When a large amount of grease needs to be drained, personnel can open the drain valve at the drain pipe 14. When the liquid level in the circulation tank 2 is higher than the degreasing baffle 13, the grease entering the circulation tank 2 can be drained through the drain pipe 14 because it is connected to the circulation tank 2. During drainage, the degreasing baffle 13 acts as a barrier; once the liquid level is lower than the degreasing baffle 13, drainage will cease, thus reducing the amount of cleaning liquid discharged. This allows for the removal of floating grease and a small amount of cleaning liquid. During operation, the water level detector 12 can detect the liquid level in the degreasing cleaning tank 1 and the circulation tank 2. When the preset position is reached, the oil drain pipe 14 will be closed. At the same time, the replenishment pipe and the water replenishment pipe 9 can be connected in advance so that the cleaning fluid in the degreasing cleaning tank 1 can be replenished after the oil drain pipe 14 is closed. The replenishment can be stopped after the water level detector 12 detects that the liquid level in the degreasing cleaning tank 1 has reached the preset standard after replenishment. The cleaning can then continue. The degreasing process does not require all the cleaning fluid to be extracted, which can reduce the time for secondary replenishment and improve processing efficiency. The water level detector 12 is model VEGALEVEL-22.

[0028] In actual operation, according to existing technology, the external degreasing support frame can be installed at the electric slide rail 16 so that the workpiece to be degreased can be placed into the degreasing cleaning tank 1. After the workpiece is placed in and the cleaning liquid is added to a suitable height, it is necessary to ensure that the cleaning liquid can flow out from the overflow port through the overflow guide box 4. The circulating water pump 5 can be started. Since the inlet of the circulating water pump 5 is installed below the circulating tank 2 and the outlet of the circulating water pump 5 is connected to the circulating outlet 6, the grease-free cleaning liquid can be drawn out from the bottom of the circulating tank 2 by the circulating water pump 5 and sent back to the circulating outlet 6 for spraying.

[0029] At this time, the cleaning fluid sprayed from the circulating water outlet 6 will be guided by the guide plate 7 and the water inlet 8 and flow towards the overflow guide box 4 again. During the water circulation process, the grease floating on the surface of the cleaning fluid in the degreasing cleaning tank 1 can be made to flow towards the overflow guide box 4, so as to push the grease in the degreasing cleaning tank 1 to the circulation tank 2 again.

[0030] Furthermore, after the grease and cleaning solution enter the circulation tank 2, the lighter grease floats on the surface of the cleaning solution in the circulation tank 2, while the heavier cleaning solution is at the bottom. By repeating the above steps, the grease cleaned out of the degreasing cleaning tank 1 can be continuously pushed into the circulation tank 2, thus avoiding secondary contamination of the workpiece by grease during the degreasing process.

[0031] When there is a large amount of grease and it needs to be drained, personnel can open the drain valve at the drain pipe 14. Since the drain pipe 14 is connected to the circulation tank 2, the grease that has entered the circulation tank 2 can be drained through the drain pipe 14. During the draining process, the degreasing baffle 13 can act as a barrier. Once the liquid level is lower than the degreasing baffle 13, the draining will stop, thereby reducing the amount of cleaning liquid discharged and allowing the floating grease and a small amount of cleaning liquid to be drained.

[0032] Meanwhile, during discharge, the water level detector 12 can detect the liquid level in the oil removal cleaning tank 1 and the circulation tank 2. When the preset position is reached, the oil drain pipe 14 will be closed. At the same time, the replenishment pipe and the water replenishment pipe 9 can be connected in advance so that the cleaning fluid in the oil removal cleaning tank 1 can be replenished after the oil drain pipe 14 is closed. The replenishment can be stopped after the water level detector 12 detects that the liquid level in the oil removal cleaning tank 1 has reached the preset standard after replenishment. The cleaning can then continue. The oil removal process does not require all the cleaning fluid to be extracted, which can reduce the time for secondary replenishment and improve processing efficiency.

[0033] Furthermore, the control components and modules used in the above-mentioned discharge solenoid valve water level detector 12 and circulating water pump 5 are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
