Abstract
Description
Technical Field
[0001] This utility model relates to a phosphating tank, and more particularly to a novel V-shaped bottom phosphating tank for phosphating. Background Technology
[0002] Phosphating of wire and coil materials is an important surface treatment technology, mainly used for wire and coil materials of metals such as steel. It improves their corrosion resistance, enhances the adhesion to coatings, and plays a role in reducing friction and lubrication in metal cold working processes. Phosphating is a process in which chemical and electrochemical reactions form a phosphate chemical conversion film. The metal coil is immersed in the phosphating solution, and a layer of water-insoluble crystalline phosphate conversion film, namely the phosphate film, is deposited on the metal surface. The phosphate film can isolate the metal from direct contact with the environment, thereby preventing the metal from being corroded to a certain extent.
[0003] Wire phosphating tanks are one of the most commonly used pieces of equipment in the field of metal surface treatment. They are mainly used to phosphate wires to form a protective film on their surface, thereby improving the wires' corrosion resistance, strength, and toughness. The working principle of wire phosphating tanks is to immerse the wires in a phosphating solution containing phosphates and other components, and to form a phosphating film on the wire surface through a chemical reaction. Wire phosphating tanks are suitable for phosphating wires of various specifications.
[0004] Traditional wire rod phosphating tanks often adopt an overall sloping bottom or tapered bottom design. Due to the limited suction of the pump, only the phosphating slag near the suction port can be effectively removed, while the slag far from the suction port tends to accumulate at the bottom of the tank, directly contacting the wire rod and causing product quality defects. This increases the cycle of cleaning the phosphating slag at the bottom of the phosphating tank, thereby reducing the overall production capacity. Utility Model Content
[0005] This utility model addresses the aforementioned technical deficiencies in existing wire phosphating tanks by providing a novel V-shaped bottom phosphating tank specifically for phosphating.
[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:
[0007] This utility model provides a novel V-shaped bottom phosphating tank specifically for phosphating, including a processing box. The phosphating tank body is located inside the processing box. A V-shaped bottom groove is formed at the bottom of the inner wall of the phosphating tank. A wire roll is movably connected inside the V-shaped bottom groove. A suction pipe is installed inside the V-shaped bottom groove. Suction holes are formed on the side surface of the suction pipe. A discharge port is formed on one side of the suction pipe. A support block is fixedly connected to the side surface of the suction pipe. By installing the V-shaped bottom groove, using a one-to-one V-shaped groove bottom with the wire roll, and each V-shaped groove bottom is equipped with an independent suction pipe, which is connected to an external circulation vertical centrifugal pump, the phosphating slag can be discharged immediately. This ensures that the phosphating slag can be uniformly and efficiently removed, avoiding the problem of slag accumulation at the bottom of the tank. This not only directly reduces the cleaning cycle of the phosphating tank and reduces the labor intensity of maintenance personnel, but also improves the overall production capacity.

[0017] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:
[0018] This utility model provides a novel V-shaped bottom phosphating tank for phosphating. By installing a V-shaped bottom tank, with a one-to-one V-shaped bottom matching the wire coil, each V-shaped bottom is equipped with an independent suction pipe and connected to an external circulation vertical centrifugal pump. This enables the immediate discharge of phosphating slag, ensuring that the phosphating slag can be uniformly and efficiently removed, avoiding the problem of slag accumulation at the bottom of the tank.

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0032] In some embodiments, such as Figure 1 - Figure 9 As shown, a novel V-shaped bottom phosphating tank for phosphating is provided, including a processing box 1, a phosphating tank 2 inside the processing box 1, a V-shaped bottom groove 3 at the bottom of the inner wall of the phosphating tank 2, a wire roll 4 movably connected inside the V-shaped bottom groove 3, a suction pipe 5 inside the V-shaped bottom groove 3, suction holes 6 on the side surface of the suction pipe 5, a discharge outlet 7 on one side of the suction pipe 5, a support block 8 fixedly connected to the side surface of the suction pipe 5, an injection pipe 9 fixedly connected to one side of the inner wall of the phosphating tank 2, a connecting flange 10 fixedly sleeved on the side surface of the injection pipe 9, the injection pipe 9 extending into the interior of the phosphating tank 2, and a suction pipe 11 fixedly connected to one side of the inner wall of the phosphating tank 2, a connecting flange 2 12 fixedly sleeved on the side surface of the suction pipe 11, the suction pipe 11 extending into the interior of the phosphating tank 2. In use, the operator first connects the suction pipe 5 to an external vertical centrifugal pump. Next, using a special hoist, the wire coil 4 is suspended in the V-shaped bottom groove 3 of the phosphating tank 2. Through the injection pipe 9, the phosphating solution is slowly injected into the phosphating tank 2 until the wire coil 4 is completely submerged. After the wire coil 4 comes into contact with the phosphating solution, a chemical reaction occurs. These reactions cause a layer of phosphating film that meets specific process requirements to gradually form on the surface of the wire coil 4. During the phosphating process, the phosphating slag produced settles at the bottom of the V-shaped bottom groove 3. Then, the external vertical centrifugal pump is started. The suction hole 6 on the side surface of the suction pipe 5 is directly opposite the bottom of the V-shaped bottom groove 3. Under the operation of the vertical centrifugal pump, the phosphating slag is sucked into the suction pipe 5. The phosphating slag enters the slag removal system outside the tank through the discharge port 7 of the suction pipe 5 for further processing. In order to maintain the purity and activity of the phosphating solution in the phosphating tank 2, the staff will also regularly extract and replace the phosphating solution through the extraction pipe 11 to ensure that each phosphating treatment achieves the best results.
[0033] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an L-shaped plate 13 is fixedly connected to one side of the inner wall of the phosphating tank 2, a reinforcing plate 14 is fixedly connected to the outer side of the treatment box 1, a support plate 15 is fixedly connected to the bottom of the reinforcing plate 14, a connecting ear 16 is fixedly connected to the other side of the reinforcing plate 14, a connecting hole 17 is opened inside the connecting ear 16, a load-bearing plate 18 is fixedly connected to one side of the treatment box 1, there are three V-shaped bottom grooves 3 arranged in a straight line, there are three wire rolls 4 arranged in a straight line, there are three suction tubes 5 arranged in a straight line, there are multiple suction holes 6, and there are three discharge outlets 7 arranged in a straight line.
[0034] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the diameter of the injection pipe 9 is smaller than the diameter of the extraction pipe 11, the diameter of the connecting flange 10 is smaller than the diameter of the connecting flange 12, the reinforcing plate 14 is fixedly connected by the support plate 15, the support plate 15 is distributed in a rectangular array, there are multiple connecting ears 16 arranged in a straight line, there are multiple connecting holes 17 arranged in a straight line, and the load-bearing plate 18 is distributed in a rectangular array.
[0035] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the working principle of this new type of V-shaped bottom phosphating tank is as follows: When in use, the operator first connects the suction pipe 5 to the external vertical centrifugal pump, and then uses a special hoist to suspend the wire coil 4 in the V-shaped bottom groove 3 of the phosphating tank 2. Through the injection pipe 9, the phosphating solution is slowly injected into the phosphating tank 2 until the wire coil 4 is completely submerged. After the wire coil 4 comes into contact with the phosphating solution, a chemical reaction occurs. These reactions cause a layer of phosphating film that meets the specific process requirements to gradually form on the surface of the wire coil 4. During the phosphating process, the phosphating slag produced settles at the bottom of the V-shaped bottom groove 3.
[0036] Next, the external vertical centrifugal pump is started. The suction hole 6 on the side surface of the suction pipe 5 is directly opposite the bottom of the V-shaped bottom tank 3. Under the operation of the vertical centrifugal pump, the phosphating slag is sucked into the suction pipe 5. The phosphating slag enters the slag removal system outside the tank through the discharge port 7 of the suction pipe 5 for further processing. In order to maintain the purity and activity of the phosphating solution in the phosphating tank 2, the staff will also regularly extract and replace the phosphating solution through the liquid extraction pipe 11 to ensure that each phosphating treatment can achieve the best results.
[0037] Subsequently, the entire processing box 1, through the ingenious combination of reinforcing plate 14 and supporting plate 15, achieves both structural stability and safety, providing solid support for an efficient and safe phosphating process.
[0038] In summary, when using this new type of V-shaped bottom phosphating tank, the worker connects the suction pipe 5 to the vertical centrifugal pump, suspends the wire coil 4 in the V-shaped bottom tank 3, and injects phosphating solution until it is completely submerged. A phosphating film is formed on the surface of the wire coil 4, and the phosphating slag settles at the bottom of the V-shaped bottom tank 3. The centrifugal pump is then started, and the phosphating slag is discharged through the suction pipe 5.
