Description

Technical Field

[0001] This application relates to the technical field of steel strand production, and in particular to a phosphating apparatus for steel strand wire rods. Background Technology

[0002] Steel strand wire rod is a hot-rolled wire rod specifically used for manufacturing prestressed steel wire and steel strand. It belongs to high-strength prestressed steel and is widely used in construction projects such as bridges and nuclear power plants. Before leaving the factory, the steel strand undergoes a phosphate treatment process. This process forms a phosphate film on the surface of the steel strand to protect the surface quality of the steel wire and extend the service life of the steel strand.

[0003] Currently, the method of phosphating steel strands by placing them into a phosphating bath is problematic. Since steel strands are composed of many steel strands, directly placing them into the phosphating bath can lead to inconsistent phosphating film thickness and a long phosphating film formation time.

[0004] Therefore, a new phosphating device is urgently needed. Utility Model Content

[0005] To address the issue of inconsistent phosphate film thickness in existing phosphate treatment devices for steel strands, this application provides a phosphate treatment device for steel strands.

[0006] The phosphating device for steel strand wire rod provided in this application adopts the following technical solution: A phosphating apparatus for steel strand wire rod includes: Phosphating tank, containing phosphating solution; A concentration adjustment module is connected to the phosphating tank and used to adjust the concentration of the phosphating solution; A phosphorus slag filtration module is connected to the phosphating tank and is used to filter the phosphorus slag in the phosphating tank. The auxiliary phosphating module includes a phosphating support, a phosphating beam, a phosphating swing arm, a phosphating frame, a swing arm driver, a lifting driver, and a moving driver. The phosphating support is slidably mounted on the ground. The moving driver provides the power for moving the phosphating support. The phosphating beam is slidably mounted on the phosphating support in a vertical direction. The lifting driver is mounted on the phosphating support and provides the power for moving the phosphating beam. The middle part of the phosphating swing arm is rotatably mounted on the phosphating beam. The output end of the swing arm driver is connected to the end of the phosphating swing arm. The other end of the phosphating swing arm is connected to the phosphating frame. The steel strand coil is hung on the phosphating frame and sways in the phosphating solution with the help of the phosphating frame.

[0007] By adopting the above technical solution, the combination of the phosphating swing arm and the swing arm driver can realize the swing of the steel strand coil hanging on the phosphating frame in the phosphating solution, thereby making the phosphating solution in the phosphating tank flow, ensuring the consistency of the phosphating solution concentration in the phosphating tank, promoting full and uniform contact between the phosphating solution and the surface of the steel strand, thus significantly improving the consistency of the phosphating film thickness and shortening the film formation time.

[0008] Optionally, the phosphating frame includes a frame body and connecting rods. The frame body is U-shaped, and the connecting rods pass through both ends of the frame body and through the center hole of the steel strand coil.

[0009] By adopting the above technical solution, the phosphating frame is designed as a combination structure of a U-shaped frame and connecting rods, which facilitates rapid and batch loading and unloading of materials through external equipment (such as overhead cranes), greatly optimizing the operation process and improving production efficiency.

[0010] Optionally, a flexible anti-collision ring is fitted on the connecting rod. There are multiple anti-collision rings arranged at intervals, and a steel strand is placed between any two adjacent anti-collision rings.

[0011] By adopting the above technical solution, flexible anti-collision rings are spaced on the connecting rod, forming a physical isolation between adjacent steel strand coils. This effectively prevents the steel strand coils from colliding with each other during frequent shaking, thus avoiding scratches or damage to the formed phosphate film and ensuring the surface quality of the product. At the same time, the flexible rings can also play a buffering role, reducing the overall swing momentum.

[0012] Optionally, the auxiliary phosphating module further includes a fixing ring with a threaded hole. Both ends of the frame are provided with through holes, and the end of the connecting rod passes through the two through holes in sequence and then passes into the threaded hole.

[0013] By adopting the above technical solution, the connection between the connecting rod and the frame is reliably locked by using a fixing ring with a threaded hole and the thread at the end of the connecting rod, ensuring that the connecting rod will not come loose from the frame when the phosphated frame is subjected to swing load.

[0014] Optionally, the auxiliary phosphating module further includes a first guide and a second guide, wherein the first guide is disposed between the phosphating support and the phosphating beam, and the second guide is disposed between the phosphating support and the ground.

[0015] By adopting the above technical solution, a second guide component is set between the phosphate support and the ground, and a first guide component is set between the phosphate support and the phosphate beam, providing precise guidance for the movement of the phosphate support and the lifting and lowering of the phosphate beam, effectively preventing the equipment from swaying or jamming during operation.

[0016] Optionally, the concentration adjustment module includes a storage tank, a liquid guide pipe, and a liquid pump. One end of the liquid guide pipe is connected to the storage tank, and the other end is connected to the phosphating tank. The liquid pump is mounted on the guide pipe.

[0017] By adopting the above technical solution and setting up a concentration adjustment module consisting of a storage tank, a liquid guide pipe and a storage pump, high-concentration phosphating solution stock solution can be automatically and accurately replenished into the phosphating tank according to process requirements, thereby achieving stable control of the phosphating solution concentration in the phosphating tank and thus facilitating the acquisition of a stable and high-quality phosphating film.

[0018] Optionally, the phosphate residue filtration module includes a filter tank, an outlet pipe, and an outlet pump. One end of the outlet pipe is connected to the filter tank, and the other end is connected to the bottom of the phosphating tank. The outlet pump is installed on the outlet pipe.

[0019] By adopting the above technical solution and setting up a phosphate slag filtration module consisting of an outlet pipe, an outlet pump and a filter tank, the phosphate solution rich in precipitated phosphate slag can be actively drawn from the bottom of the phosphate bath, effectively maintaining the cleanliness of the phosphate solution and preventing phosphate slag from adhering to the surface of the workpiece and affecting the phosphate quality.

[0020] Optionally, the phosphorus slag filtration module further includes a recovery pipe, a recovery tank, and a recovery pump. One end of the recovery pipe is connected to the separation tank, and the other end is connected to the recovery tank. The recovery pump is installed on the recovery pipe.

[0021] By adopting the above technical solution, a phosphating liquid recovery channel was constructed by adding a recovery pipe, a recovery tank and a recovery pump after the filtration module, thus realizing the initial recovery of phosphating liquid resources.

[0022] Optionally, the phosphate residue filtration module further includes an inlet pipe and an inlet pump, the inlet pipe connecting the recovery tank and the phosphating tank, and the inlet pump being mounted on the inlet pipe.

[0023] By adopting the above technical solution and setting up an inlet pipe and inlet pump, a complete phosphating solution recycling system is formed, which greatly improves the utilization rate of phosphating solution and reduces production costs.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining the phosphating swing arm and the swing arm driver, the steel strand wire rod is made to oscillate regularly during the phosphating process, which increases the fluidity of the phosphating solution and makes the concentration of the phosphating solution in different parts of the phosphating tank consistent. This not only improves the phosphating efficiency but also ensures the phosphating quality.

[0025] 2. The concentration adjustment module can monitor and automatically replenish high-concentration stock solution in real time, ensuring that the phosphating reaction always proceeds within the optimal concentration range, thus guaranteeing stable phosphating quality. Simultaneously, the phosphate residue filtration module continuously removes precipitated impurities generated during the reaction, preventing them from adhering to the steel strands and affecting the formation of the phosphating film, thereby improving the film quality.

[0028] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0029] refer to Figure 1 A phosphating device for steel strand wire rod includes a phosphating tank 1, a concentration adjustment module 2, a phosphate slag filtration module 3, and an auxiliary phosphating module 4.

[0030] The phosphating tank 1 contains phosphating solution. A concentration adjustment module 2 stores a high-concentration phosphating solution, connects to the phosphating tank 1, and inputs the high-concentration phosphating solution into the tank, thereby adjusting the concentration of the phosphating solution in the tank 1. A phosphate slag filtration module 3 has a filtration function; it connects to the phosphating tank 1 and is used to extract the phosphating solution from the bottom of the tank 1 to filter out the phosphate slag. An auxiliary phosphating module 4 is used to place steel strand coils into the phosphating tank 1 and to agitate the coils to improve the phosphating effect and efficiency.

[0031] refer to Figures 3 to 5 The auxiliary phosphating module 4 includes a phosphating support 41, a phosphating beam 42, a phosphating swing arm 43, a phosphating frame 44, a swing arm driver 45, a lifting driver 46, and a moving driver 47. The phosphating support 41 is slidably mounted on the ground. The output end of the moving driver 47 is connected to the phosphating support 41, providing power for its movement. The phosphating beam 42 is slidably mounted vertically on the phosphating support 41. The lifting driver 46 is mounted on the phosphating support 41 and its output end is connected to the phosphating beam 42, providing power for its movement. The middle part of the phosphating swing arm 43 is rotatably mounted on the phosphating beam 42. The driver 45 is mounted on the phosphate beam 42. The output end of the swing arm driver 45 is connected to the end of the phosphate swing arm 43. The other end of the phosphate swing arm 43 is connected to the phosphate frame 44. The phosphate frame 44 is located below the phosphate beam 42 and is used to hang the steel strand coil. The swing arm driver 45 causes the end of the phosphate swing arm 43 to rotate continuously by moving its output end, which in turn causes the phosphate frame 44 to swing continuously, and ultimately causes the steel strand coil to swing in the phosphate bath 1.

[0032] refer to Figure 4 and Figure 5 To facilitate the operator's placement of the steel strand coil on the phosphated frame 44, which includes a frame body and connecting rods, the frame body is U-shaped with through holes at both ends. The connecting rods pass through these through holes, and the steel strand coils are hung on the connecting rods. The connecting rods and the frame body are detachable. The operator uses external equipment to lift the steel strand coils and then passes the connecting rods through the center hole of the steel strand coils.

[0033] refer to Figure 3 and Figure 6Since multiple steel strand coils are suspended on the connecting rod, flexible anti-collision rings 48 are fitted onto the connecting rod to prevent collisions between the steel strand coils and thus damage to the surface phosphate layer. Multiple anti-collision rings 48 are installed at equal intervals, with a steel strand coil placed between two adjacent anti-collision rings 48, thereby separating the two adjacent steel strand coils. Furthermore, the flexibility of the anti-collision rings 48 also reduces the momentum of the steel strand coils during oscillation.

[0034] refer to Figure 5 and Figure 6 To prevent the connecting rod from detaching from or falling off the frame during the oscillation of the steel strand coil in the phosphating tank 1, the auxiliary phosphating module 4 also includes a fixing ring 49. The fixing ring 49 has internal threads, and one end of the connecting rod also has threads. This threaded end passes through the through hole and then into the threaded hole of the fixing ring 49. By turning the fixing ring 49, the connecting rod is positioned in the direction of its own axis, and finally the connecting rod is detached from the frame.

[0035] refer to Figure 3 and Figure 4 To improve the stability of the phosphating support 41 during movement, a second guide is provided between the phosphating support 41 and the ground. Simultaneously, to improve the stability of the phosphating beam 42 during movement, a first guide is provided between the phosphating beam 42 and the phosphating support 41. Both the first and second guides are combinations of sliders and guide rails.

[0036] It should be noted that the swing arm actuator 45, the lifting actuator 46, and the moving actuator 47 are all cylinders.

[0037] refer to Figure 2 and Figure 3 The concentration adjustment module 2 includes a storage tank 21, a delivery pipe 22, and a storage pump 23. The storage tank 21 is located to the side of the phosphating tank 1 and contains a high-concentration phosphating solution. One end of the delivery pipe 22 connects to the storage tank 21, and the other end connects to the phosphating tank 1. The storage pump 23 is mounted on the delivery pipe 22, meaning the delivery pipe 22 passes through the storage pump 23. The storage pump 23 adds the phosphating solution from the storage tank 21 into the phosphating tank 1.

[0038] refer to Figure 2 and Figure 3The phosphate slag filtration module 3 includes a filter tank 31, an outlet pipe 32, an outlet pump 33, a recovery pipe 34, a recovery tank 35, a recovery pump 36, an inlet pipe 37, and an inlet pump 38. One end of the outlet pipe 32 is connected to the phosphating tank 1, and the other end is connected to the filter tank 31. The outlet pump 33 is installed on the outlet pipe 32, which is connected to the bottom of the phosphating tank 1 and is used to absorb the phosphating liquid at the bottom of the phosphating tank 1. This part of the phosphating liquid contains phosphate slag and flows into the filter tank 31 through the outlet pipe 32 and the outlet pump 33. The phosphate slag is filtered in the filter tank 31, and the supernatant after filtration enters the recovery tank 35 through the recovery pipe 34 and the recovery pump 36. After heating, it returns to the phosphating tank 1 through the inlet pipe 37 and the inlet pump 38. Because the concentration of this part of the phosphating liquid is low, it needs to work simultaneously with the storage tank 21 in the concentration adjustment module 2.

[0039] The implementation principle of the phosphating device for steel strand coils in this embodiment is as follows: First, the phosphating frame 44 needs to be moved to the outside of the phosphating tank 1. Then, the operator uses external equipment to place the steel strand coil onto the connecting rod. Next, by moving the phosphating support 41, the steel strand coil is moved directly above the phosphating tank 1. Then, the phosphating beam 42 is lowered until the steel strand coil hanging on the phosphating frame 44 is completely immersed in the phosphating solution. After the steel strand coil is completely immersed in the phosphating solution, the swing arm driver 45 is activated, driving the phosphating swing arm 43 to reciprocate, thereby realizing the oscillation of the steel strand coil within the phosphating solution. The oscillation of the steel strand coil improves the phosphating effect of the phosphating solution. Furthermore, the oscillating steel strand coil can agitate the phosphating solution, ensuring that the concentration of the phosphating solution in different parts of the phosphating tank 1 remains consistent, further improving the phosphating effect and efficiency.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
