Description

Technical Field

[0001] This application relates to the field of anti-leakage technology for steel wire heat treatment pickling tanks, and in particular to an anti-leakage protection device for steel wire heat treatment pickling tanks. Background Technology

[0002] Pickling equipment for steel wire heat treatment plays a crucial role in the metal wire product processing industry. Its core function is to remove impurities such as oxides and oil from the surface of the steel wire through the pickling process, thereby improving the subsequent processing performance of the steel wire and the quality of the final product. However, existing steel wire heat treatment pickling tanks have limitations in design and use.

[0003] First, many current pickling tank designs require operators to manually guide steel wires into the acidic solution. During this process, operators' hands are highly susceptible to contact with the highly corrosive hydrochloric acid, leading to serious injuries such as skin burns and chemical dermatitis. Long-term exposure can also cause occupational health problems, such as skin hardening and respiratory damage. Furthermore, existing outlet pipe seals are often inadequate, allowing acid to leak through the joints. This not only wastes valuable resources but can also cause ground corrosion, environmental pollution, and even more serious safety accidents. These problems directly impact production efficiency and the safety and health of operators.

[0004] Therefore, how to solve the problem that manual pickling of steel wire may cause arm injuries, and how to improve the sealing performance of the pickling tank outlet pipe, have become urgent problems to be solved. Utility Model Content

[0005] The purpose of this application is to provide a leak-proof protection device for steel wire heat treatment pickling tanks, which solves the problems in the prior art that manual pickling of steel wire may cause arm injuries and that the sealing performance of the pickling tank outlet pipe is insufficient.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] On one hand, this application provides a leak-proof protection device for a steel wire heat treatment pickling tank, including: a storage tank and an outlet pipe disposed on the storage tank, and further including:

[0008] A rubber disc, connected to the liquid storage tank, is fitted onto the outer wall of the liquid outlet pipe;

[0009] A fixed cylinder is coaxially mounted on the liquid storage tank with the liquid outlet pipe and sleeved on the outer wall of the liquid outlet pipe. It has an internal cavity, and the rubber disc is located in the cavity. The fixed cylinder is provided with a sliding groove that penetrates its side wall.

[0010] Pressing element, used to press against the rubber disc;

[0011] An active component, located inside the fixed cylinder, is used to control the pressing element to press or release the rubber disc.

[0012] An adjustment component is connected to the movable component through the slide groove at one end. By moving the adjustment component, the movable component can be moved, thereby controlling the pressing element to press or release the rubber disc.

[0013] In this design, the storage tank is used to store pickling solutions and other treatment fluids. The rubber disc has good elasticity and sealing properties, allowing it to tightly seal against the outlet pipe under pressure, preventing liquid leakage. The fixed cylinder is coaxially mounted on the storage tank with the outlet pipe, also fitting around the outer wall of the outlet pipe. The fixed cylinder has an internal cavity to accommodate the rubber disc and the movable component. The groove allows the adjusting component to operate outside the fixed cylinder, thereby controlling the movement of the movable component. One side of the pressing component has a surface that contacts the rubber disc, enhancing the sealing effect by pressing the rubber disc. When the pressing component presses the rubber disc, the rubber disc further seals against the outlet pipe, reducing the risk of leakage. The movable component, located inside the fixed cylinder, controls the pressing and releasing actions of the pressing component. Through precise control of the movable component, effective pressing and releasing of the rubber disc by the pressing component can be achieved. One end of the adjusting component passes through the groove and connects to the movable component. The operator can move the adjusting component to move the movable component within the fixed cylinder, thereby controlling the pressing or releasing of the rubber disc by the pressing component. This solution can effectively prevent the leakage of pickling solution at the outlet pipe, ensuring the safety and stability of the steel wire pickling process.

[0014] Optionally, the active component includes:

[0015] A beveled disc is axially rotatably disposed inside the fixed cylinder, and has beveled teeth on the side opposite to the liquid storage tank. The beveled disc can be rotated by adjusting the adjusting component.

[0016] The threaded rod has multiple threads arranged radially along the bevel gear disk. One end of each threaded rod is rotatably connected to the fixed cylinder. Each threaded rod is provided with a bevel gear that meshes with the bevel gear disk.

[0017] Linear sliders, the same number as the threaded rods, are disposed on each threaded rod. By rotating the bevel gear disk, each linear slider can move synchronously and linearly towards the periphery or center of the bevel gear disk.

[0018] The number of connecting parts is the same as that of the linear sliders, with one end rotatably connected to each linear slider and the other end rotatably connected to the pressing part.

[0019] In this design, when the adjusting component drives the bevel gear disk to rotate, the bevel gear disk meshes with the bevel gears on each threaded rod. Therefore, the rotation of the bevel gear disk drives all the threaded rods to rotate synchronously. Since the threaded rods and the linear slider are connected by a threaded engagement, the rotation of the threaded rods is converted into linear movement of the linear slider. When the threaded rod rotates clockwise (or counterclockwise, depending on the design direction of the thread), the linear slider moves towards the outer periphery of the fixed cylinder; conversely, when the threaded rod rotates counterclockwise (or clockwise), the linear slider moves towards the center of the fixed cylinder.

[0020] The movement of the linear slider is transmitted to the pressing component through the connector. When the connector rotates to a position closer to perpendicular to the threaded rod, the effective lever arm of the connector (i.e., the horizontal distance from the point of rotation of the connector to the point of connection with the pressing component) reaches its maximum. Since the movement of the linear slider on the threaded rod is linear, and the connector converts these linear movements into pressure on the pressing component through rotation, maximizing the lever arm in the vertical position leads to maximizing the pressure on the pressing component.

[0021] Conversely, as the connector rotates further away from a perpendicular position to the threaded rod, the effective lever arm decreases. This means that even if the linear slider moves the same distance on the threaded rod, the pressure exerted by the connector on the pressing element will decrease accordingly due to the reduced lever arm.

[0022] By controlling the direction and extent of rotation of the threaded rod, precise control can be achieved over the pressing or releasing of the rubber disc. This allows for increased pressure on the rubber disc when needed to improve sealing, while reducing pressure when not needed to avoid over-pressuring or damaging the rubber disc.

[0023] Optionally, the adjustment assembly includes a moving block and a positioning element. The bottom of the moving block is provided with a connecting rod, one end of which passes through the slide groove and is connected to the bevel gear plate. The positioning element is used to fix the position of the moving block.

[0024] When the pressure of the pressing element on the rubber disc needs to be adjusted, the operator applies external force to push the moving block along the slide. The movement of the moving block drives the connecting rod, which in turn rotates the bevel gear disc. The rotation of the bevel gear disc is transmitted to the threaded rod through the bevel gear, causing the threaded rod to rotate. The rotation of the threaded rod is converted into linear movement of the linear slider, which is then transmitted to the pressing element through the connecting piece, thus adjusting the pressure of the rubber disc. When the desired position is reached, the position of the moving block is fixed using the positioning piece to ensure that the pressing element can maintain its current pressure condition.

[0025] Optionally, the positioning member and the moving block are connected by a tension spring. The fixed cylinder is provided with a plurality of positioning hole groups, which are arranged along the circumference of the fixed cylinder. Each positioning hole group includes two positioning holes symmetrically arranged on both sides of the slide groove. One end of the positioning member has two symmetrically arranged positioning arms, which pass through the moving block. By stretching the positioning member, the positioning arms can enter or disengage from each of the positioning hole groups.

[0026] When the moving block needs to be moved, the operator stretches the positioning element, disengaging the positioning arm from the current positioning hole assembly. During this stretching process, the tension spring is extended. The moving block can then move freely within the groove until it reaches the desired position. Once the moving block reaches the desired position, the operator releases the positioning element. Due to the elastic force of the tension spring, the positioning arm automatically enters the positioning hole assembly below the moving block's position, thus fixing the moving block's position. This ensures that the moving block will not move on its own unless subjected to external force.

[0027] Optionally, the liquid storage tank is provided with a storage box, and two support plates are provided on the top of the liquid storage tank on two opposite sides. A lifting assembly for driving the storage box to rise and fall is provided between the two support plates.

[0028] Optionally, the lifting assembly includes: a first bidirectional screw and a second bidirectional screw arranged parallel between two support plates. The first bidirectional screw has a rotating part for rotating the first bidirectional screw. The first bidirectional screw and the second bidirectional screw are connected by a transmission component. The first bidirectional screw has a right-hand thread on one side and a left-hand thread on the other side. The second bidirectional screw has the same thread as the first bidirectional screw. A slider is provided on each of the right-hand thread side, the left-hand thread side, the right-hand thread side, and the left-hand thread side of the second bidirectional screw. A lifting rod is rotatably connected to the bottom of each slider. The lifting rods on the two sliders connected to the first bidirectional screw and the two sliders connected to the second bidirectional screw are rotatably connected to two opposite sides of the storage box.

[0029] When the first bidirectional screw rotates, due to its bidirectional thread design, the sliders on the right-hand and left-hand thread sides will move relative to or towards each other along the first bidirectional screw. Simultaneously, since the second bidirectional screw has the same thread as the first bidirectional screw and rotates synchronously via a transmission component, the slider on the second bidirectional screw will also move in the same manner. As the sliders move, one end of the lifting rod, rotatably connected to its bottom, will also move accordingly. Because the other end of the lifting rod is rotatably connected to the storage box, the vertical distance between the storage box and the threaded rod changes when the sliders on the same threaded rod move relative to or towards each other. Therefore, the storage box will rise or fall as the lifting rod moves.

[0030] Optionally, the transmission component is a transmission belt, with a driving pulley provided at one end of the first bidirectional screw and a driven pulley provided at one end of the second bidirectional screw, and the driving pulley and the driven pulley are connected by a transmission belt for transmission.

[0031] Optionally, the liquid storage tank is provided with two limiting rods, which are located on opposite sides of the storage box. A locking block is slidably provided on the limiting rod, and the locking block is located on the top of the storage box.

[0032] As the storage box rises or falls, the locking block slides along the limit rod. Because the limit rod provides a fixed path for the locking block, it ensures the storage box remains stable during movement, reducing swaying or offset, thereby improving the stability and reliability of the entire system.

[0033] Compared with existing technologies, the beneficial effects achieved by this application are as follows: In this utility model, a rubber disc is installed at the outlet pipe of the storage tank, increasing the sealing performance of the outlet pipe joint. By adjusting the component and driving the movable component, the pressing component is controlled to press the rubber disc, ensuring that the rubber disc is tightly pressed against the outlet pipe, thus increasing the sealing performance and effectively preventing leakage of pickling solution at the outlet pipe joint, ensuring the safety and stability of the steel wire pickling process. This not only reduces acid waste but also avoids problems such as ground corrosion and environmental pollution.

[0034] Furthermore, the storage box in the liquid storage tank of this invention can be automatically raised and lowered via a lifting assembly. During the pickling process, the operator places the steel wire into the storage box, and then the lifting assembly lowers the storage box into the pickling tank, thus achieving pickling of the steel wire. The operator does not need to come into contact with the pickling solution during the process. This avoids the operator directly inserting the steel wire into the acidic solution by hand. It significantly reduces the risk of the operator's hands coming into contact with highly corrosive hydrochloric acid solution, thereby effectively preventing injuries such as skin burns and chemical dermatitis.

Detailed Implementation

[0043] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0044] Example 1

[0045] This embodiment describes a leak-proof protection device for a steel wire heat treatment pickling tank. (Refer to...) Figure 1The anti-leakage protection device for the steel wire heat treatment pickling tank in this embodiment includes a storage tank 1, which is used to store pickling solution and other treatment liquids. An inlet pipe 12 and an outlet pipe 2 are provided on the storage tank 1. A rubber disc 3 is also provided on the storage tank 1, which is tightly fitted onto the outer wall of the outlet pipe 2. The rubber disc 3 has good elasticity and sealing properties, and can tightly fit against the outer wall of the pipe to seal the joint of the outlet pipe 2. Simultaneously, the rubber disc 3 can tightly fit against the outlet pipe 2 under pressure to prevent liquid leakage. A fixed cylinder 4 is also provided on the storage tank 1, coaxially arranged with the outlet pipe 2. The fixed cylinder 4 is fitted onto the outer wall of the outlet pipe 2, and has a cavity inside, within which the rubber disc 3 is located. A sliding groove 41 is provided on the fixed cylinder 4, penetrating its side wall. In this embodiment, a pressing member 5 is also provided on one side of the rubber disc 3. The pressing member 5 is used to press against the rubber disc 3, and its opposite side has a surface that fits against the rubber disc 3. When the pressing element 5 presses the rubber disc 3, the rubber disc 3 will further conform to the liquid outlet pipe 2, thereby increasing the sealing effect and reducing the risk of leakage.

[0046] refer to Figure 2 In this embodiment, the pressing component 5 is used to control the pressing or releasing of the rubber disc 3 via the movable component 6. Specifically, the movable component 6 is located inside the fixed cylinder 4 and includes a bevel gear disc 61, threaded rods 62, linear sliders 64, and connecting components 65. The bevel gear disc 61 is axially rotatably mounted inside the fixed cylinder 4, with a bevel gear disc 61 positioned on the side opposite the liquid storage tank 1. The bevel gear disc 61 can be rotated by adjusting the adjusting component 7. Multiple threaded rods 62 are arranged radially along the bevel gear disc 61, with one end rotatably connected to the fixed cylinder 4. Each threaded rod 62 has a bevel gear 63 that meshes with the bevel gear disc 61. The number of linear sliders 64 is the same as the number of threaded rods 62, and they are mounted on each threaded rod 62. Rotating the bevel gear disc 61 allows each linear slider 64 to move synchronously and linearly towards the periphery or center of the bevel gear disc 61. The number of connecting components 65 is the same as the number of linear sliders 64, with one end rotatably connected to each linear slider 64 and the other end rotatably connected to the pressing component 5.

[0047] refer to Figure 3 and Figure 4 This embodiment also includes an adjustment component 7 for adjusting the movable component 6. One end of the adjustment component 7 passes through the slide groove 41 and is connected to the movable component 6. Moving the adjustment component 7 can drive the movable component 6 to move, thereby controlling the pressing member 5 to press or release the rubber disc 3. Specifically, the adjustment component 7 includes a moving block 71, and a connecting rod 74 is provided at the bottom of the moving block 71. One end of the connecting rod 74 passes through the slide groove 41 and is connected to the bevel gear disc 61. By setting the adjustment component 7, the operator can operate it outside the fixed cylinder 4, thereby making it more convenient to control the movement of the movable component 6.

[0048] During operation, when adjusting the pressure of the pressing element 5 on the rubber disc 3, the operator applies external force to push the moving block 71 along the slide groove 41. The movement of the moving block 71 causes the connecting rod 74 to move, which in turn causes the bevel gear disc 61 to rotate. The bevel gear disc 61 meshes with the bevel gears 63 on each threaded rod 62, so the rotation of the bevel gear disc 61 causes all the threaded rods 62 to rotate synchronously. Since the threaded rods 62 and the linear slider 64 are connected by threads, the rotation of the threaded rods 62 is converted into linear movement of the linear slider 64. When the threaded rod 62 rotates clockwise (or counterclockwise, depending on the design direction of the thread), the linear slider 64 moves towards the outer periphery of the fixed cylinder 4. Conversely, when the threaded rod 62 rotates counterclockwise (or clockwise), the linear slider 64 moves towards the center of the fixed cylinder 4.

[0049] The movement of the linear slider 64 is transmitted to the pressing member 5 through the connector 65. When the connector 65 rotates to a position closer to perpendicular to the threaded rod 62, the effective lever arm of the connector 65 (i.e., the horizontal distance from the point of rotation of the connector 65 to the point of connection with the pressing member 5) reaches its maximum. Since the movement of the linear slider 64 on the threaded rod 62 is linear, and the connector 65 converts these linear movements into pressure on the pressing member 5 through rotational connection, the maximization of the lever arm in the vertical position leads to the maximization of the pressure on the pressing member 5.

[0050] Conversely, as the connector 65 rotates further away from a perpendicular position to the threaded rod 62, the effective lever arm decreases. This means that even if the linear slider 64 moves the same distance on the threaded rod 62, the pressure exerted by the connector 65 on the pressing member 5 will decrease accordingly due to the reduced lever arm.

[0051] By controlling the direction and degree of rotation of the threaded rod 62, precise control can be achieved over the pressing element 5 to tighten or release the rubber disc 3. This allows for increased pressure on the rubber disc 3 when needed to improve sealing, while reducing pressure when not needed to avoid over-tightening or damaging the rubber disc 3.

[0052] In this embodiment, the operator can move the adjusting component 7 to drive the movable component 6 within the fixed cylinder 4, thereby controlling the pressing or releasing of the rubber disc 3 by the pressing component 5. This effectively prevents leakage of pickling solution at the outlet pipe 2, ensuring the safety and stability of the steel wire pickling process.

[0053] To prevent the movable block 71 from moving on its own without being subjected to external force, the adjusting assembly 7 in this embodiment also includes a positioning element 72. Specifically, the positioning element 72 is connected to the movable block 71 via a tension spring 73. In one embodiment, the positioning element 72 also has a spring post 722, one end of which passes through the interior of the tension spring 73 and is slidably connected to the movable block 71. Further, the fixed cylinder 4 is provided with a plurality of positioning hole groups 42, which are arranged circumferentially along the fixed cylinder 4. Each positioning hole group 42 includes two positioning holes symmetrically arranged on both sides of the slide groove 41. One end of the positioning element 72 has two symmetrically arranged positioning arms 721, which pass through the movable block 71. By stretching the positioning element 72, the positioning arms 721 can enter or disengage from each positioning hole group 42.

[0054] When the moving block 71 needs to be moved, the operator stretches the positioning element 72, causing the positioning arm 721 to disengage from the current positioning hole group 42. During the stretching process, the tension spring 73 is extended. The moving block 71 can then move freely within the slide 41 until it reaches the desired position. Once the moving block 71 reaches the desired position, the operator releases the positioning element 72. Due to the elastic force of the tension spring 73, the positioning arm 721 automatically enters the positioning hole group 42 below the moving position of the moving block 71, thereby fixing the position of the moving block 71. This ensures that the moving block 71 will not move on its own unless subjected to external force.

[0055] Example 2:

[0056] This is based on the same inventive concept as Embodiment 1. (See reference...) Figure 1 and Figure 5 The difference from Embodiment 1 is that, in this embodiment, the liquid storage tank 1 is equipped with a storage box 8. Two support plates 11 are provided on the top of two opposite sides of the liquid storage tank 1, and a lifting assembly 9 for driving the storage box 8 to rise and fall is provided between the two support plates 11. Specifically, the lifting assembly 9 includes a first bidirectional screw 91 and a second bidirectional screw 92 arranged parallel to each other between the two support plates 11. The first bidirectional screw 91 has a rotating part 93 for rotating it, and the first bidirectional screw 91 and the second bidirectional screw 92 are connected by a transmission member 94. The first bidirectional screw 91 has a right-hand thread on one side and a left-hand thread on the other side, and the second bidirectional screw 92 has the same thread as the first bidirectional screw 91. A slider 95 is provided on each of the right-hand thread side of the first bidirectional screw 91, the left-hand thread side of the first bidirectional screw 91, the right-hand thread side of the second bidirectional screw 92, and the left-hand thread side of the second bidirectional screw 92, and a lifting rod 96 is rotatably connected to the bottom of each slider 95. Furthermore, the lifting rods 96 on the two sliders 95 connected to the first bidirectional screw 91, and the lifting rods 96 on the two sliders 95 connected to the second bidirectional screw 92, are respectively rotatably connected to the two opposite sides of the storage box 8.

[0057] When the first bidirectional screw 91 rotates, due to its bidirectional thread design, the sliders 95 located on the right-hand thread side and the left-hand thread side will move relative to or towards each other along the first bidirectional screw 91. Simultaneously, since the second bidirectional screw 92 has the same thread as the first bidirectional screw 91 and rotates synchronously via the transmission member 94, the sliders 95 on the second bidirectional screw 92 will also move in the same manner. As the sliders 95 move, one end of the lifting rod 96, which is rotatably connected to its bottom, will also move accordingly. Since the other end of the lifting rod 96 is rotatably connected to the storage box 8, the vertical distance between the storage box 8 and the threaded rod 62 changes when the sliders 95 on the same threaded rod 62 move relative to or towards each other. Therefore, the storage box 8 will rise or fall as the lifting rod 96 moves.

[0058] In this embodiment, the transmission component 94 uses a transmission belt. Specifically, a driving pulley 941 is provided on one end of the first bidirectional screw 91, and a driven pulley 942 is provided on one end of the second bidirectional screw 92. The driving pulley 941 and the driven pulley 942 are connected by a transmission belt. Belt drives are simple in structure, provide smooth transmission, and can buffer and absorb vibrations, making them widely used.

[0059] In this embodiment, the liquid storage tank 1 is equipped with two limiting rods 13 located on opposite sides of the storage box 8. A locking block 14 is slidably mounted on each limiting rod 13, positioned at the top of the storage box 8. When the storage box 8 rises or falls, the locking block 14 slides along the limiting rod 13. Because the limiting rod 13 provides a fixed path for the locking block 14, the locking block 14 ensures the storage box 8 remains stable during movement, reducing shaking or displacement of the storage box 8 during movement, thereby improving the stability and reliability of the entire system.

[0060] During the pickling process, the operator places the steel wire into the storage box 8, and then lowers the storage box 8 into the pickling chamber using the lifting component 9, thus achieving pickling of the steel wire. The operator does not need to come into contact with the pickling solution during the process. This avoids the operator directly feeding the steel wire into the acidic solution by hand. It significantly reduces the risk of the operator's hands coming into contact with the highly corrosive hydrochloric acid solution, thereby effectively preventing injuries such as skin burns and chemical dermatitis.

[0061] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
