Description

Technical Field

[0001] The present application relates to the field of hot-dip galvanizing, and in particular to a zinc liquid purification device for hot-dip galvanizing processing. Background Art

[0002] A common hot-dip galvanizing purification method is that the operator pours the reducing agent and zinc liquid into a container, then stirs the zinc liquid in the container to fully mix the zinc liquid and the reducing agent, and then pours the zinc liquid in the container into another container with a filter. The filter filters the impurities in the zinc liquid, thereby completing the purification of the zinc liquid. In the process of purifying the zinc liquid, the operator needs to transfer the materials to multiple containers during the process of feeding, stirring and collecting the zinc liquid, and the process of purifying the zinc liquid is complicated. Utility Model Content

[0003] In order to purify the zinc liquid more conveniently, the present application provides a zinc liquid purification device for hot-dip galvanizing processing.

[0004] The present application provides a zinc liquid purification device for hot-dip galvanizing using the following technical solution:

[0007] A filter plate is connected in the box body, a spring is connected to the filter plate, the upper end of the spring is connected to the inner wall of the box body, and a stirring component for stirring the material is also provided on the cover body, and the stirring component is located above the filter plate.

[0008] By adopting the above technical solution, when the zinc liquid needs to be purified, the operator opens the cover plate and the sealing plate, pours the reducing agent into one of the hoppers, pours the zinc liquid into the other hopper, then covers the hopper with the sealing plate, opens the valve on the connecting pipe, and the reducing agent and the zinc liquid enter the box through the connecting pipe, then closes the valve on the connecting pipe and covers the cover; in the process of covering the cover, the cover drives the stirring assembly to move to the bottom of the box, and at the same time, the stirring assembly pushes the filter plate downward, and the movement of the filter plate stretches the spring. When the cover is closed, the filter plate contacts the bottom wall of the box, and the stirring assembly is started to stir the material.

[0009] After the stirring is completed, the stirring assembly is closed, and the cover is pulled upward to move the stirring assembly upward. At the same time, the spring recovers its deformation and pulls the filter plate upward. The zinc liquid is filtered while the filter plate moves. When the spring returns to its initial state, the filter plate is located above the zinc liquid and the impurities are located on the support plate. The operator can easily take out the impurities. Finally, the zinc liquid in the box can be released by opening the valve on the discharge pipe. The operating steps in the process of purifying the zinc liquid are simplified, so that the operator can purify the zinc liquid more conveniently.

[0010] Optionally, the stirring assembly includes a stirring shaft rotatably connected to the lower surface of the cover body, at least one fan blade is connected to the stirring shaft, and a motor for driving the stirring shaft to rotate is also installed on the cover body.

[0011] By adopting the above technical solution, during the process of closing the cover body, the stirring shaft moves downward and pushes the filter plate to move. When the material needs to be stirred, the motor is started, and the motor drives the stirring shaft and the fan blades to rotate, thereby stirring and mixing the material.

[0012] Optionally, a pad is connected to the lower end of the stirring shaft, and the diameter of the pad is larger than the diameter of the stirring shaft.

[0013] By adopting the above technical solution, the pad increases the contact area between the stirring shaft and the filter plate, reducing the occurrence of rapid wear of the filter plate.

[0014] Optionally, the connecting pipe gradually slopes downward in a direction approaching the box body.

[0015] By adopting the above technical solution, the material in the hopper can enter the box more smoothly.

[0017] By adopting the above technical solution, the slider cooperates with the slide groove so that the filter plate is slidably connected to the box body.

[0018] Optionally, the box body is also provided with a filter press assembly for filtering the material.

[0019] By adopting the above technical solution, the filter press assembly squeezes the impurities on the filter plate, causing the zinc liquid attached to the impurities to fall, thereby being able to better collect the zinc liquid.

[0020] Optionally, the filter press assembly includes a pressing plate located on the filter plate, a lower surface of the cover body is connected to a hydraulic cylinder, and a telescopic rod of the hydraulic cylinder is connected to the pressing plate.

[0021] By adopting the above technical solution, when the cover body is lowered, the pressure plate enters the box body. When the cover body is pulled upward, the hydraulic cylinder is controlled to work, so that the hydraulic cylinder pushes the pressure plate to move downward. At the same time, the spring recovers its deformation and pulls the filter plate to move upward, so that the distance between the filter plate and the pressure plate is gradually reduced. At the same time, the pressure plate and the filter plate cooperate to squeeze the impurities on the filter plate and squeeze out the zinc liquid attached to the impurities. When the extrusion is completed, the hydraulic cylinder is controlled to work to move the pressure plate upward.

[0022] Optionally, filter holes are provided on the pressing plate.

[0023] By adopting the above technical solution, the zinc liquid can be better separated from the impurities.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application embodiment discloses a zinc liquid purification device for hot dip galvanizing. Figure 1 and Figure 2, including a box body 1, two connecting pipes 2 are fixedly connected to the box body 1, and the end of the connecting pipe 2 away from the box body 1 is connected to the hopper 3, and the connecting pipe 2 gradually tilts upward in the direction close to the hopper 3; the hopper 3 and the top of the box body 1 are designed to be open, which is convenient for adding materials. A valve is installed on the connecting pipe 2 to control the flow of materials. A sealing plate 31 is detachably connected to the top of the hopper 3 to close the hopper 3. The top of the box body 1 is detachably connected to a cover body 11 through a lock to ensure the sealing of the box body 1.

[0034] Reference Figure 2 and Figure 3 The bottom of the box 1 is fixedly connected with a discharge pipe 12, and a valve is also installed on the discharge pipe 12 to control the discharge of zinc liquid. The box 1 is also provided with a filter plate 4, and a slider 41 is connected to the side wall of the filter plate 4. Correspondingly, a slide groove 13 adapted to the slider 41 is provided on the inner wall of the box 1. The length direction of the slide groove 13 extends along the height direction of the box 1, and the slider 41 is slidably inserted in the corresponding slide groove 13; this structural design ensures that the filter plate 4 can stably slide up and down in the box 1, and ensures the smoothness and accuracy of the sliding process.

[0035] The upper surface of the slider 41 is fixedly connected with a spring 5 , and the upper end of the spring 5 is fixed to the top groove wall of the slide groove 13 ; when the spring 5 is not acted upon by an external force, the spring 5 suspends the filter plate 4 so that the filter plate 4 is located at the upper part of the box body 1 .

[0036] A stirring assembly 6 is provided on the cover body 11, and the stirring assembly 6 is located above the filter plate 4 and is used for stirring the material; the stirring assembly 6 includes a stirring shaft 61 rotatably connected to the lower surface of the cover body 11, and the axial direction of the stirring shaft 61 is arranged along the height direction of the box body 1, and the stirring shaft 61 is located above the filter plate 4. At least one fan blade 62 is fixedly connected to the bottom side wall of the stirring shaft 61. In order to drive the stirring shaft 61 to rotate, a motor 63 is also installed on the cover body 11. The output shaft of the motor 63 is coaxial with the stirring shaft 61, and the output shaft of the motor 63 passes through the cover body 11 and is fixed to the stirring shaft 61; when the motor 63 is started, the stirring shaft 61 and the fan blade 62 are driven to rotate, thereby achieving sufficient stirring of the material.

[0037] When the zinc liquid needs to be purified, the operator pours the reducing agent into one of the hoppers 3 and the zinc liquid into the other hopper 3, covers the two sealing plates 31, then puts the stirring shaft 61 into the box body 1, and lowers the cover body 11 and the stirring shaft 61, so that the stirring shaft 61 pushes the filter plate 4 to move downward, and the filter plate 4 stretches the spring 5 at the same time.

[0038] When the cover 11 is closed, the filter plate 4 contacts the inner bottom wall of the box body 1. At this time, the valve on the connecting pipe 2 is controlled to control the amount of reducing agent and zinc liquid entering the box body 1, and then the motor 63 is started. The motor 63 drives the stirring shaft 61 and the fan blades 62 to rotate, so as to stir and mix the reducing agent and the zinc liquid. In order to reduce the occurrence of rapid wear of the filter plate 4 by the stirring shaft 61, a pad 64 is fixedly connected to the lower end surface of the stirring shaft 61. The diameter of the pad 64 is larger than the diameter of the stirring shaft 61. The pad 64 increases the force area of ​​the filter plate 4 and reduces the occurrence of rapid wear of the filter plate 4.

[0039] When the stirring is completed, the cover body 11 is lifted upwards, and the movement of the cover body 11 drives the pad 64, the stirring shaft 61 and the fan blade 62 to move upwards. At the same time, the spring 5 recovers its deformation and pulls the filter plate 4 to move upwards. The filter plate 4 filters the zinc liquid and pushes the impurities in the zinc liquid to move upwards; when the pad 64 is out of contact with the filter plate 4, the filter plate 4 moves to above the zinc liquid, and the operator can easily clean the impurities on the filter plate 4 at this time; when the zinc liquid needs to be collected, the valve on the discharge pipe 12 is opened, and the zinc liquid flows out of the box 1; the steps required for purifying the zinc liquid are reduced, so that the operator can purify the zinc liquid more conveniently.

[0040] Since zinc liquid is attached to the impurities on the filter plate 4, in order to better collect the zinc liquid, a filter press assembly 7 is added to the box body 1. The filter press assembly 7 specifically includes a pressing plate 71 located above the filter plate 4, a stirring shaft 61 passes through the pressing plate 71 and is slidably plugged with the pressing plate 71, a fan blade 62 is located between the pressing plate 71 and the filter plate 4, and a filter hole is also provided on the pressing plate 71; a hydraulic cylinder 72 is fixedly connected to the lower surface of the cover body 11, and a telescopic rod of the hydraulic cylinder 72 faces downward and is connected to the pressing plate 71.

[0041] When the cover body 11 is pulled upward, the hydraulic cylinder 72 is controlled to work, so that the pressure plate 71 moves downward. At the same time, the spring 5 recovers its deformation and pulls the filter plate 4 upward. The distance between the filter plate 4 and the pressure plate 71 gradually decreases, so that the pressure plate 71 can exert pressure on the impurities on the filter plate 4 to squeeze them, and the zinc liquid attached to the impurities can be squeezed out more effectively. The zinc liquid flows out through the filter plate 4 and the filter holes, thereby improving the purity and collection rate of the zinc liquid.

[0042] The implementation principle of a zinc liquid purification device for hot-dip galvanizing processing in an embodiment of the present application is: pour the zinc liquid into one of the hoppers 3, pour the reducing agent into the other hopper 3, and control the valve on the connecting pipe 2 to control the hopper 3 and the amount of the reducing agent entering the hopper 3; lower the cover body 11, the pad 64 pushes the filter plate 4 to move downward, and the filter plate 4 stretches the spring 5 at the same time. After covering the cover body 11, start the motor 63 to stir the material in the box body 1.

[0043] After the stirring is completed, the cover body 11 is pulled upward, and at the same time, the spring 5 recovers its deformation and pulls the filter plate 4 upward, and the hydraulic cylinder 72 is controlled to work to move the pressing plate 71 downward; the impurities on the filter plate 4 are squeezed to make the zinc liquid in the impurities fall to the bottom of the box body 1; then the valve on the discharge pipe 12 is controlled to control the zinc liquid in the box body 1 to flow out of the box body 1; finally, the hydraulic cylinder 72 is controlled to work to move the pressing plate 71 upward until the pressing plate 71 returns to its initial position, and the cover body 11 is pulled to separate the pressing plate 71 from the box body 1. At this time, the operator cleans the impurities on the filter plate 4.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
