Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic polishing equipment, and in particular to an electrolytic polishing equipment for the internal flow channel of pipes and valves. Background Technology

[0002] Electrolytic polishing equipment for internal flow channels of pipes and valves is mainly used to electrolytically polish the surface of internal flow channels of pipes and valves. Its core function is to improve the surface quality of internal flow channels through electrochemical principles.

[0003] By using the pipe and valve fittings as the anode and immersing them in the electrolyte, and then connecting them to a DC power supply, an oxidation reaction occurs on the anode surface. The metal atoms dissolve into ions and enter the electrolyte, which can quickly remove microscopic defects such as burrs, scratches, and oxide scale from the inner surface. At the same time, a uniform passivation film is formed, which improves the surface corrosion resistance. However, during the electrolytic polishing process of the inner flow channel of the pipe and valve fittings, the electrolyte will produce sediment impurities after prolonged use in the electrolytic cell. If these impurities are not cleaned in time, they will affect the polishing effect and electrolyte performance, thereby reducing the polishing quality and production efficiency of the pipe and valve fittings. Usually, a tray is placed at the bottom of the cell to collect and clean the sediment.

[0004] Considering that when the tray is lifted out of the electrolytic cell, impurities may easily diffuse into the electrolyte, which not only increases the maintenance cost of the electrolyte but may also cause secondary contamination of pipes and valves, affecting product quality, an electrolytic polishing device for the internal flow channels of pipes and valves is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electrolytic polishing device for the internal flow channel of pipes and valves, which aims to solve the problem that when the tray is pulled out of the electrolytic cell in the prior art, impurities are easily diffused into the electrolyte, which not only increases the maintenance cost of the electrolyte, but may also cause secondary pollution of pipes and valves, affecting product quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electrolytic polishing device for the internal flow channel of a pipe valve, comprising an electrolytic cell, a support frame slidably connected to the inner surface of the electrolytic cell, a counterweight block slidably connected to the inner surface of the support frame, a hinge plate hinged to the bottom of the outer surface of the counterweight block, a hinge baffle hinged to the bottom of the inner surface of the support frame, a telescopic baffle slidably connected to the outer surface of the hinge baffle, the bottom of the outer surface of the hinge plate hinged to the top of the outer surface of the telescopic baffle, the outer surface of the telescopic baffle inserted into the bottom of the inner surface of the support frame, and a limit component provided on the outer surface of the hinge baffle;

[0007] The limiting component includes a limiting block, the outer surface of which is fixedly connected to the outer surface of the hinged baffle, and the inner surface of the telescopic baffle has a limiting groove, the inner surface of which is slidably connected to the outer surface of the limiting block.

[0010] As a further description of the above technical solution:

[0011] The outer surface of the insertion rod penetrates and slides through the inner surface of the counterweight, and the outer surface of the insertion rod is inserted into the top of the inner surface of the support frame.

[0012] As a further description of the above technical solution:

[0013] The bottom of the electrolytic cell and the bottom of the support frame are both designed in a V-shape.

[0014] As a further description of the above technical solution:

[0015] Both the hinged baffle and the telescopic baffle are provided in two sets, and are symmetrically distributed at the bottom of the support frame.

[0016] As a further description of the above technical solution:

[0017] The outer surface of the telescopic baffle is set as an inclined surface on the right side, and the outer surfaces of the two sets of telescopic baffles are in contact with each other.

[0018] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the cooperation of the telescopic baffle and the hinged baffle, when cleaning impurities, the counterweight descends and drives the telescopic baffle and the hinged baffle to flip and extend, completely sealing the impurities at the bottom of the support frame. This effectively prevents impurities from diffusing into the electrolyte during the lifting of the support frame, ensuring the purity of the electrolyte, maintaining the stability of electropolishing, and improving the polishing quality of pipes and valves.

[0024] 2. In this utility model, by designing the baffle to be telescopic, the problem of motion interference that may occur when the two sets of baffles are flipped is cleverly solved. The telescopic baffle can slide along the surface of the hinged baffle under the action of the hinged plate and the counterweight, ensuring full coverage and sealing of the bottom opening of the support frame while making the movement of each component smoother and avoiding structural damage or sealing failure caused by interference.

[0033] 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.

[0034] Reference Figures 1-3This utility model provides an embodiment of an electrolytic polishing device for the internal flow channels of pipes and valves, including an electrolytic cell 1. The electrolytic cell 1 is a key component used to hold the electrolyte and provide a reaction site for the electrolytic polishing of the internal flow channels of pipes and valves. Its internal space can accommodate the pipes and valves and the electrolyte. Polishing treatment of the internal flow channels of pipes and valves is achieved through electrolytic reaction. A support frame 2 is slidably connected to the inner surface of the electrolytic cell 1, allowing the support frame 2 to move vertically along the inside of the electrolytic cell 1, effectively lifting it out of the electrolytic cell 1. A counterweight 4 is slidably connected to the inner surface of the support frame 2, allowing the counterweight 4 to move vertically along the inner surface of the support frame 2, using its own weight to drive the movement of related components. The counterweight 4 is made of stainless steel, which has a high density to meet the counterweight requirements. Stainless steel also has good corrosion resistance and can work stably for a long time in the electrolyte environment. It is not easy to rust or corrode. The bottom of the outer surface of the counterweight 4 is hinged to a hinge plate 5, which allows the hinge plate 5 to move as the counterweight 4 descends. The bottom of the inner surface of the support frame 2 is hinged to a hinge baffle 6, which allows the hinge baffle 6 to flip along the bottom of the inner surface of the support frame 2. The outer surface of the hinge baffle 6 is slidably connected to a telescopic baffle 7, which allows the telescopic baffle 7 to slide along the outer surface of the hinge baffle 6. The bottom of the outer surface of the hinge plate 5 is hinged to the top of the outer surface of the telescopic baffle 7, which allows the hinge plate 5 to drive the telescopic baffle 7 and the hinge baffle 6 to flip along the bottom of the support frame 2 and to drive the telescopic baffle 7 to slide along the surface of the hinge baffle 6. The outer surface of the telescopic baffle 7 is inserted into the bottom of the inner surface of the support frame 2 to ensure the sealing effect of the telescopic baffle 7 and the hinge baffle 6 on impurities and prevent impurities from leaking.

[0035] Reference Figure 4 A limiting component 8 is provided on the outer surface of the hinged baffle 6. The limiting component 8 includes a limiting block 801, the outer surface of which is fixedly connected to the outer surface of the hinged baffle 6, providing guidance and limiting for the sliding of the telescopic baffle 7. A limiting groove 802 is provided on the inner surface of the telescopic baffle 7, which is used to cooperate with the limiting block 801 to ensure the stability and accuracy of the telescopic baffle 7 when sliding on the hinged baffle 6 and to prevent it from deviating. The inner surface of the limiting groove 802 is slidably connected to the outer surface of the limiting block 801. This sliding connection method ensures that the telescopic baffle 7 can slide relative to the hinged baffle 6, and also ensures the accuracy of its sliding path through the limiting effect.

[0036] Reference Figure 2 , Figure 5A threaded sleeve 10 is fixedly connected to the top of the inner surface of the support frame 2. The threaded sleeve 10 provides the basis for the threaded connection of the insertion rod 9. The inner surface of the threaded sleeve 10 is threaded through and connected to the insertion rod 9, so that the insertion rod 9 can always be fixed in the designated position. The outer surface of the insertion rod 9 is slidably connected to the inner surface of the counterweight 4. The outer surface of the insertion rod 9 is inserted into the top of the inner surface of the support frame 2, so that when the insertion rod 9 is inserted into the counterweight 4, the counterweight 4 can be restricted to the designated position.

[0037] Reference Figures 1-3 The bottom of the electrolytic cell 1 and the bottom of the support frame 2 are both designed in a V-shape. The V-shape design helps impurities to gather towards the center of the bottom, facilitating subsequent cleaning operations. There are two sets of hinged baffles 6 and telescopic baffles 7, which are symmetrically distributed at the bottom of the support frame 2. The symmetrical distribution of the two sets ensures full coverage of the bottom opening of the support frame 2, ensuring that impurities can be effectively sealed and preventing omissions. The right side of the outer surface of the telescopic baffle 7 is designed as a slope, and the outer surfaces of the two sets of telescopic baffles 7 are in contact with each other. The slope design allows the two sets of telescopic baffles 7 to make tight contact when they are fitted together, forming a good sealing effect and preventing impurities from leaking from the gaps.

[0038] Reference Figure 1 The top of the outer surface of the support frame 2 is fixedly connected to a lifting column 3, which provides a lifting connection point for the support frame 2, making it convenient to use lifting equipment to lift the support frame 2 out of the electrolytic cell 1 for impurity cleaning and other operations. The top of the outer surface of the electrolytic cell 1 is provided with an operation hole 11, which provides an operating space for the operator to unscrew the insertion rod 9, release the fixation of the counterweight 4, and thus start the impurity cleaning process.

[0039] Reference Figures 2-3 , Figure 6 The outer surface of the counterweight 4 is fixedly connected to a T-shaped block 13. The outer surface of the T-shaped block 13 is slidably connected to the inner surface of the support frame 2, so that the counterweight 4 can always move vertically along the designated position by sliding the T-shaped block along the inner surface of the support frame 2, without losing the effect of deviating from the predetermined position. The inner surface of the support frame 2 is provided with damping texture 12. The outer surface of the T-shaped block 13 is in contact with the outer surface of the damping texture 12. By sliding the T-shaped block 13 and the surface of the damping texture 12, the speed at which the counterweight 4 descends can be reduced, so as to prevent the two baffles from flipping too fast and the impact liquid from dispersing the impurities located at the bottom of the support frame 2.

[0040] Working principle: When it is necessary to clean the impurities precipitated in the electrolytic cell 1, first unscrew the two sets of insert rods 9 through the operating hole 11 to release the fixation of the counterweight 4, causing it to move downwards due to gravity. As the counterweight 4 moves downwards, it will simultaneously drive the two sets of telescopic baffles 7 and hinge baffles 6 to flip inwards along the bottom of the support frame 2 through the two sets of hinge plates 5. When the two sets of telescopic baffles 7 and hinge baffles 6 are in contact with the bottom of the support frame 2, the counterweight 4 will continue to move downwards, causing the counterweight 4 to move inwards under the action of the hinge plates 5. The telescopic baffle 7 slides along the surface of the hinged baffle 6, allowing the two sets of telescopic baffles 7 at the bottom of the support frame 2 to fit together and adapt to the V-shaped design at the bottom of the support frame 2. This allows impurities at the bottom of the support frame 2 to be sealed by the telescopic baffle 7 and the hinged baffle 6, preventing the impurities deposited at the bottom from spreading into the electrolyte when the support frame 2 is lifted. Then, by using the hook on the lifting equipment to connect with the lifting column 3 on the support frame 2, the support frame 2 is lifted out of the electrolytic cell 1, thereby cleaning the impurities deposited in the electrolytic cell 1.

[0041] 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.
