Description

Technical Field

[0001] This utility model relates to cold heading steel wire production equipment, specifically to a cold heading steel wire rinsing device. Background Technology

[0002] Before phosphate coating of cold-heading steel wire, rinsing is required to remove residual acid, chloride ions, and other impurities from the wire surface. Existing rinsing devices have rinsing tanks equipped with inlets and overflow outlets. During rinsing, a C-shaped hook carrying the cold-heading steel wire is immersed in the rinsing solution using a lifting device. Rinsing is achieved by the natural flow of water generated by gravity-fed inlet water. Overflow is achieved by the rise in liquid level caused by the immersion of the cold-heading steel wire and the C-shaped hook, expelling chloride ions and other impurities from the solution. The technical problem with existing rinsing devices is that the crevices where the cold-heading steel wire intersects are difficult to clean thoroughly, resulting in residual acid and chloride ions. These residual acids and chloride ions can enter the phosphate coating tank with the steel wire during subsequent phosphate coating, contaminating the phosphate coating solution, affecting the quality of the phosphate film, reducing the corrosion resistance and product performance of the steel wire, and increasing production and maintenance costs. Furthermore, frequent changes to the phosphate coating solution also lead to decreased production efficiency and increased costs. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a rinsing device for cold heading steel wire with better rinsing effect.

[0004] Technical Solution: This utility model discloses a rinsing device for cold heading steel wire, comprising a rinsing tank with a water inlet and an overflow outlet, and a circulating pump. The inlet of the circulating pump is connected to the outlet on the rinsing tank, and the outlet of the circulating pump is divided into a first outlet pipe and a second outlet pipe. Vibrators are provided on both sides of the rinsing tank for supporting C-shaped hooks and vibrating the C-shaped hooks to separate the gaps in the cold heading steel wire. A spray pipe is horizontally arranged on the inner wall of the rinsing tank opposite to the overflow outlet, and the spray pipe is connected to the first outlet pipe. Several first fan-shaped nozzles are spaced apart on the spray pipe for continuously rinsing the surface of the cold heading steel wire entering and exiting the rinsing tank and blowing impurities on the surface of the tank liquid to the overflow outlet for discharge. Several second fan-shaped nozzles are spaced apart along the height direction on the side of the rinsing tank, and each second fan-shaped nozzle is connected to the second outlet pipe to form a directional circulating flow of the tank liquid, continuously rinsing the surface and gaps of the cold heading steel wire.

[0005] Furthermore, a long strip-shaped overflow baffle is installed in the rinsing tank. The overflow baffle is at a certain angle to the length of the rinsing tank, and the height of the overflow baffle is higher than the overflow port. It is used to guide the impurities blown out and the wastewater containing chloride ions to the overflow port and discharge it outside the tank.

[0006] Furthermore, the cold heading steel wire rinsing device also includes an overflow pipe connected to an overflow port, and a filter screen is installed on the overflow pipe to prevent pipe blockage.

[0007] Furthermore, the liquid outlet is located at the bottom side of the rinsing tank.

[0008] Furthermore, the circulating pump adopts a corrosion-resistant diaphragm pump.

[0009] Furthermore, the vibrator is an inertial vibrator.

[0010] Furthermore, supports are installed on both sides of the rinsing tank, and the vibrator is fixed on the supports.

[0011] Beneficial Effects: Compared with the prior art, this invention has the following advantages: This invention uses a circulating pump to extract the bath liquid and deliver it to each fan-shaped nozzle. During the process of the cold heading steel wire entering and leaving the rinsing tank, the surface of the cold heading steel wire is subjected to high-pressure rinsing through the first fan-shaped nozzle. After the cold heading steel wire is immersed in the bath liquid, a vibrator is used to vibrate the C-shaped hook, thereby separating the gaps in the cold heading steel wire. Then, the directional circulating bath liquid formed by the second fan-shaped nozzle continuously rinsing the surface and gaps of the cold heading steel wire. Compared with the traditional gravity-flow immersion rinsing method, this invention can more effectively remove impurities such as acid and chloride ions from the surface of the cold heading steel wire, especially from the gaps in the cold heading steel wire, thereby significantly improving the rinsing efficiency and quality of the cold heading steel wire. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of a cold heading steel wire rinsing device provided in an embodiment of this utility model. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Appendix Figure 1 The accompanying figure labels are as follows:

[0015] 1. Rinse tank; 2. C-shaped hook; 3. Circulation pump; 4. Liquid outlet; 5. First outlet pipeline; 6. Spray pipeline; 7. Second outlet pipeline; 8. Second fan-shaped nozzle; 9. Water inlet; 10. Overflow outlet; 11. Support; 12. Vibrator.

[0016] like Figure 1 As shown in the figure, this utility model embodiment provides a cold heading steel wire rinsing device, including a rinsing tank 1, a circulating pump 3, and a vibrator 12. The rinsing tank 1 has a water inlet 9 and an overflow outlet 10 on both sides along its length, with the water inlet 9 located on the left side and the overflow outlet 10 located on the right side. The rinsing tank 1 is used to hold rinsing liquid, which is tap water. The water inlet 9 is connected to a tap water supply pipe, and the overflow outlet 10 is connected to an overflow pipe. The replacement of the rinsing liquid can be achieved through water supply and overflow.

[0017] A liquid outlet 4 is located at the bottom left side of the rinsing tank 1, and the inlet of the circulation pump 3 is connected to the liquid outlet 4. The position of the liquid outlet 4 must ensure that the circulation pump 3 can draw a large amount of tank liquid. The outlet of the circulation pump 3 is divided into a first outlet pipe 5 and a second outlet pipe 7.

[0018] A spray pipe 6 is horizontally installed on the inner left side of the rinsing tank 1. The spray pipe 6 is connected to the first outlet pipe 5. Several first fan-shaped nozzles are installed at intervals on the spray pipe 6. Several second fan-shaped nozzles 8 are installed at intervals along the height direction on the side of the rinsing tank 1. Each second fan-shaped nozzle 8 is connected to the second outlet pipe 7.

[0019] The rinsing tank 1 is provided with supports 11 on both sides, and a vibrator 12 is fixed on each of the two supports 11. In this embodiment, the vibrator 12 is an inertial vibrator, model YZS-25-6.

[0020] A long strip-shaped overflow baffle is provided in the rinsing tank 1. The overflow baffle is welded and fixed to the inner wall of the rinsing tank 1 and is at an angle of 35° to 45°, preferably 40°, to the length direction of the rinsing tank 1. The height of the overflow baffle is higher than the overflow port 10.

[0021] The treatment of iron oxide scale on the surface of cold-heading steel wire mainly involves hydrochloric acid and sulfuric acid. Therefore, residual acid remains on the surface and in the crevices of the cold-heading steel wire before rinsing. This acid enters the rinsing solution after rinsing, causing corrosion to ordinary circulating pumps and affecting their service life. Therefore, in this embodiment, the circulating pump 3 is a corrosion-resistant diaphragm pump.

[0022] In addition, a filter screen is installed on the overflow pipe to intercept larger particles of impurities and prevent the pipe from becoming clogged.

[0023] The working principle of this utility model is as follows:

[0024] Sufficient rinsing solution is injected into rinsing tank 1 to ensure that the cold-heading steel wire is completely submerged. The circulation pump 3 is started, and the C-shaped hook 2, carrying the cold-heading steel wire, is immersed in the rinsing solution using a lifting device. During this process, each first fan-shaped nozzle sprays the rinsing solution at high pressure onto the cold-heading steel wire, rinsing its surface. The rinsing solution sprayed from each first fan-shaped nozzle also blows away impurities from the surface of the rinsing solution in rinsing tank 1. The blown-away impurities and wastewater containing chloride ions are diverted through the overflow baffle to the overflow port 10 and discharged outside the tank.

[0025] Subsequently, the two ends of the C-shaped hook 2 are respectively placed on two vibrators 12, and the cold-heading steel wire is completely immersed in the bath liquid. The vibrators 12 are turned on, causing the C-shaped hook 2 to vibrate, thereby separating the gaps in the cold-heading steel wire. The high-pressure spray of the bath liquid from each of the second fan-shaped nozzles 8 creates a directional circulation flow in the bath liquid in the rinsing tank 1, thereby continuously rinsing the surface and gaps of the cold-heading steel wire. After rinsing, the C-shaped hook 2 carrying the cold-heading steel wire is lifted out using lifting equipment. During this process, each of the first fan-shaped nozzles rinses the surface of the cold-heading steel wire again.

[0026] After the cold heading steel wire is rinsed and lifted out, the cold heading steel wire rinsing device continuously replenishes water and overflows, replacing the tank solution and reducing the precipitation of impurities such as chloride ions in the tank solution, preparing for the next cold heading steel wire rinsing.

[0027] This invention solves the problem of traditional cold heading steel wire rinsing devices failing to remove impurities from the gaps in the steel wire. Testing shows that after rinsing cold heading steel wire using the device provided in this embodiment, the residual amount of chloride ions and other substances on the surface and in the gaps of the cold heading steel wire is significantly reduced, effectively preventing contamination of the subsequent phosphating tank. The rust-preventing ability and lubrication quality of the phosphating film are improved, enhancing the market competitiveness of the steel wire products.
