Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing, in particular to a device for adjusting the thickness of a hot-dip galvanized coating. Background Art

[0002] Hot-dip galvanizing can protect steel from corrosion. By immersing the steel in molten zinc, a zinc coating is formed, which can provide effective corrosion protection and extend the service life of the steel. To avoid the situation that a thinner coating fails to achieve the protection effect and a thicker coating increases the processing cost, it is necessary to adjust the thickness of the coating. For this purpose, a device for adjusting the thickness of the galvanized layer of hot-dip galvanized steel is required.

[0003] In the patent application No.: CN202323209362.5, a device for adjusting the thickness of the galvanized layer of hot-dip galvanized steel is disclosed. By retracting and releasing the fixing rope to drive the lifting plate to move up and down, device failures and waste of zinc liquid can be avoided, thereby improving the practicability of the device. And by starting the first motor to drive the rotating plate to rotate, materials of different specifications can be fixed and the galvanizing effect can be improved, thereby improving the working efficiency of the device.

[0004] However, during the use of this device, since the flue gas generated by galvanizing is somewhat toxic, directly discharging it into the air not only pollutes the air but also may be inhaled by the staff, which is harmful to their health. At the same time, the clamping plates used in this device clamp the materials, there is a risk of falling off, and the subsequent salvage is rather troublesome. Or the zinc liquid splashed when falling from a high place into the zinc liquid bucket may splash onto the staff and cause burns. Therefore, a device for adjusting the thickness of a hot-dip galvanized coating is proposed, which can provide certain protection functions for the operation of this device. Summary of the Utility Model

[0005] Aiming at the problems in the prior art, the utility model provides a device for adjusting the thickness of a hot-dip galvanized coating, which can provide certain protection functions for the operation of this device.

[0006] The technical solution adopted by the utility model to solve its technical problems is a device for adjusting the thickness of a hot-dip galvanized coating, including a hot-dip galvanizing adjustment device. The inner bottom of the hot-dip galvanizing adjustment device is fixedly installed with a zinc liquid bucket. On one side inside the hot-dip galvanizing adjustment device, above the side of the zinc liquid bucket, a wind collecting hood is fixedly installed. One side of the wind collecting hood is fixedly connected to one end of an exhaust pipe. The other end of the exhaust pipe is fixedly connected to the air extraction end of an air extractor. The air outlet end of the air extractor is fixedly connected to one end of an outlet pipe. The other end of the outlet pipe is fixedly connected to the air inlet of an air purifier.

[0007] By adopting the above technical solution, the exhaust fan can extract all the toxic gases in the hot-dip galvanizing adjusting device and discharge them into the air purifier for purification, avoiding air pollution by toxic gases and ensuring the health of the staff.

[0008] Through the setting of the object-supporting mesh box, it can prevent the material from falling off during the clamping process of the clamping plate, and can hold the falling material to avoid situations such as salvage. At the same time, some small materials that cannot be clamped by the clamping plate can be directly placed in the object-supporting mesh box for hot-dip galvanizing operation.

[0009] Specifically, a fan door is movably connected to the side of the hot-dip galvanizing adjusting device away from the exhaust pipe.

[0010] By adopting the above technical solution, during hot-dip galvanizing, the fan door can be closed, reducing the air circulation inside the hot-dip galvanizing adjusting device, so that the toxic gases can be directly extracted by the exhaust pipe.

[0011] Specifically, a lifting device is installed on the inner top of the hot-dip galvanizing adjusting device. The bottom of the lifting device is rotatably connected to a connecting plate, and the bottom of the connecting plate is movably installed with clamping plates, and there are two clamping plates.

[0012] By adopting the above technical solution, the lifting device can drive the connecting plate and the clamping plates to move downward, so that the materials clamped by the clamping plates can be put into the zinc liquid bucket for hot-dip galvanizing.

[0013] Specifically, two chutes are opened at the bottom of the connecting plate. The two chutes are used for inserting the insertion blocks. The cross-sections of the insertion blocks and the chutes are both arranged in a T-shaped structure. The insertion blocks are fixedly connected to the top of the object-supporting mesh box.

[0014] By adopting the above technical solution, before hot-dip galvanizing operation, the insertion blocks at the top of the object-supporting mesh box need to be slid into the chutes first, so that the object-supporting mesh box can be installed at the bottom of the connecting plate and can wrap the two clamping plates, so that the materials clamped by the clamping plates can be caught even if they fall.

[0015] Specifically, a limiting block is movably installed near the chute on one side of the connecting plate. One side of the limiting block is fixedly connected to a pushing block. A slot is opened on the inner wall of the chute, and a magnetic attraction block is fixedly installed inside the slot. One end of the magnetic attraction block is magnetically connected to the limiting block.

[0016] By adopting the above technical solution, after the insertion blocks are all slid into the chutes, push the pushing block to push the limiting block into the slot, and let the magnetic attraction block in the slot attract one end of the limiting block, so that the chute can be blocked to prevent the object-supporting mesh box from slipping.

[0017] The beneficial effects of the present utility model:

[0018] (1) A hot-dip galvanized coating thickness adjustment device described in the present utility model can extract all the toxic gases in the hot-dip galvanized adjustment device through the setting of an exhaust fan and discharge them into the air purifier for purification, avoiding the pollution of the air by toxic gases and ensuring the physical health of the staff.

[0019] (2) A hot-dip galvanized coating thickness adjustment device described in the present utility model can prevent the material from falling off during the clamping process of the splint through the setting of the object-carrying mesh box, and can hold the falling material to avoid situations such as salvage. At the same time, some small materials that cannot be clamped by the splint can be directly placed in the object-carrying mesh box for hot-dip galvanizing operations.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] In order to provide a certain protection function for the operation of the device, as an embodiment of the present utility model, such as Figures 1 - 5As shown in the figure, a hot-dip galvanized coating thickness adjusting device of the present utility model includes a hot-dip galvanized adjusting device 1. A zinc liquid bucket 5 is fixedly installed at the inner bottom of the hot-dip galvanized adjusting device 1. A wind collecting hood 12 is fixedly installed on one side inside the hot-dip galvanized adjusting device 1 above the side of the zinc liquid bucket 5. One side of the wind collecting hood 12 is fixedly connected to one end of an air extraction pipe 8. The other end of the air extraction pipe 8 is fixedly connected to the air extraction end of an air extraction fan 9. The air outlet end of the air extraction fan 9 is fixedly connected to one end of an air outlet pipe 6. The other end of the air outlet pipe 6 is fixedly connected to the air inlet of an air purifier 7.

[0029] During use, the toxic gases generated by hot-dip galvanizing will be sucked into the air extraction fan 9 through the wind collecting hood 12 by the air extraction pipe 8. The air extraction fan 9 discharges the sucked toxic gases into the air purifier 7 through the air outlet pipe 6 for purification.

[0030] Exemplarily, as Figures 1 - 5 shown in the figure, the present utility model further includes that a fan door 2 is movably connected to the side of the hot-dip galvanized adjusting device 1 away from the air extraction pipe 8.

[0031] During use, during hot-dip galvanizing, the fan door 2 can be closed, reducing the air circulation inside the hot-dip galvanized adjusting device 1, so that the toxic gases can be directly sucked away by the air extraction pipe 8.

[0032] Exemplarily, as Figures 1 - 5 shown in the figure, the present utility model further includes that a lifting device 10 is installed at the inner top of the hot-dip galvanized adjusting device 1. The bottom of the lifting device 10 is rotatably connected to a connecting plate 3. The bottom of the connecting plate 3 is movably installed with clamping plates 13, and there are two clamping plates 13.

[0033] During use, the lifting device 10 can drive the connecting plate 3 and the clamping plates 13 to move downward, so that the materials clamped by the clamping plates 13 can be put into the zinc liquid bucket 5 for hot-dip galvanizing.

[0034] Exemplarily, as Figures 1 - 5 shown in the figure, the present utility model further includes that two chutes 14 are provided at the bottom of the connecting plate 3. The two chutes 14 are used for inserting and installing insertion blocks 11. The cross-sections of the insertion blocks 11 and the chutes 14 are both arranged in a T-shaped structure. The insertion blocks 11 are fixedly connected to the top of a material-carrying mesh box 4.

[0035] During use, before hot-dip galvanizing operation, the insertion blocks 11 at the top of the material-carrying mesh box 4 need to be slid into the chutes 14 first, so that the material-carrying mesh box 4 can be installed at the bottom of the connecting plate 3 and can wrap the two clamping plates 13, so that the materials dropped by the clamping plates 13 can be caught.

[0036] It should be noted that the object-carrying mesh box 4 is made of a metal filter mesh, which allows the zinc solution to pass through the object-carrying mesh box 4 to galvanize the materials inside it. One side of the object-carrying mesh box 4 is provided with a door that can be opened or closed, and materials that cannot be clamped by some clamping plates 13 can be put in for hot-dip galvanizing operations together.

[0037] Exemplarily, as Figures 1 - 5 shown, the present utility model further includes that a limiting block 17 is movably installed on one side of the connecting plate 3 near the sliding groove 14. One side of the limiting block 17 is fixedly connected to a pushing block 18. A slot 16 is formed in the inner wall of the sliding groove 14, and a magnetic attraction block 15 is fixedly installed inside the slot 16. One end of the magnetic attraction block 15 is magnetically connected to the limiting block 17.

[0038] During use, when the insertion block 11 completely slides into the sliding groove 14, push the pushing block 18 to push the limiting block 17 into the slot 16, so that the magnetic attraction block 15 in the slot 16 attracts one end of the limiting block 17, which can block the sliding groove 14 and prevent the object-carrying mesh box 4 from slipping.

[0039] When the present utility model is in use, before the hot-dip galvanizing operation, the insertion block 11 at the top of the object-carrying mesh box 4 needs to be slid into the sliding groove 14 first, so that the object-carrying mesh box 4 can be installed at the bottom of the connecting plate 3 and can wrap two clamping plates 13, so that even if the materials clamped by the clamping plates 13 fall, the materials can be caught. When the insertion block 11 completely slides into the sliding groove 14, push the pushing block 18 to push the limiting block 17 into the slot 16, so that the magnetic attraction block 15 in the slot 16 attracts one end of the limiting block 17, which can block the sliding groove 14 and prevent the object-carrying mesh box 4 from slipping. Then start the lifting device 10 to put the materials in the clamping plates 13 into the zinc solution bucket 5 for hot-dip galvanizing. Start the exhaust fan 9 through an external power supply and close the fan door 2. The toxic gases generated by hot-dip galvanizing will be sucked into the exhaust fan 9 by the air collecting hood 12 through the exhaust pipe 8, and the exhaust fan 9 will discharge the sucked toxic gases from the exhaust pipe 6 into the air purifier 7 for purification.
