Description

Technical Field

[0001] This utility model relates to the field of pickling equipment technology, and in particular to a hot-dip galvanizing pickling sealing device. Background Technology

[0002] Hot-dip galvanizing is a process in which molten metal reacts with an iron substrate to create an alloy layer, thus bonding the substrate and the coating together. The process begins with pickling the steel parts to remove iron oxide from their surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both. The pickled workpiece is then immersed in a hot-dip galvanizing bath, resulting in a uniform coating with strong adhesion.

[0003] Traditional steel pipe pickling tanks are generally open-topped, such as the hot-dip galvanizing pickling equipment described in Chinese Patent Publication No. CN220393915U. The pickling tank contains pickling solution. Because the top opening of the pickling tank is directly exposed, droplets are easily splashed out, and some pickling solution easily evaporates into the air, thus polluting the air and being easily inhaled by the human body, which can harm the health of operators. This provides poor protection for operators and is also inconvenient for material handling.

[0004] Therefore, it is necessary to provide a hot-dip galvanizing pickling sealing device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a hot-dip galvanizing pickling sealing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a hot-dip galvanizing pickling sealing device, comprising a tank body, a support plate provided on one side of the tank body, an electric telescopic rod with its output end facing downwards fixed to the top of the support plate, a top plate fixed to the top of the tank body, a slot provided on the side of the top plate and a hanging basket provided within the slot, a cover plate hinged to the top of the hanging basket, a plurality of equally spaced openings provided on the bottom side wall of the hanging basket, a protrusion fixed to the end of the hanging basket near the support plate, the output shaft end of the electric telescopic rod fixed to the side of the protrusion, and an opening and closing assembly provided on the outside of the cover plate.

[0007] As a further embodiment of this utility model, the opening and closing assembly includes a pressure rod fixed to the top of the support plate, the pressure rod being located directly above the end of the cover plate near the support plate.

[0008] As a further embodiment of this utility model, the bottom end of the pressure rod is provided with an arc-shaped end.

[0009] As a further embodiment of this utility model, both ends of the cover plate are fixed with joint shafts and the two joint shafts are arranged coaxially, with the joint shafts located in the middle of the cover plate.

[0010] As a further embodiment of this utility model, a first convex plate is fixed on the side of the joint shaft, and a second convex plate is fixed on the outer side wall of the hanging basket. A spring is provided between the first convex plate and the second convex plate, and the two ends of the spring are respectively fixed to the side of the first convex plate and the side of the second convex plate.

[0011] As a further embodiment of this utility model, the bottom of the pool body is fixed with an inlet pipe and an outlet pipe that communicate with the inside of the pool body, and valves are installed on both the inlet pipe and the outlet pipe.

[0012] As a further embodiment of this utility model, a base is fixed to the bottom end of the support plate, and a plurality of symmetrically distributed screw holes are provided on the top side of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The output shaft of the electric telescopic rod drives the basket to move down into the tank. The cover is automatically closed by the opening and closing assembly. The basket is immersed in the pickling solution inside the tank, allowing the pickling solution inside the tank to flow into the basket through the groove. This allows the workpiece inside the basket to be immersed in the pickling solution for pickling treatment. At this time, the top plate and cover plate seal the top of the tank, greatly reducing the evaporation and diffusion of the pickling solution inside the tank into the surrounding environment, effectively reducing air pollution and effectively improving the protection of operators.

[0015] 2. The automatic opening and closing of the cover plate is achieved through the opening and closing components, thereby eliminating the need for manual operation of opening and closing the cover plate, facilitating material feeding and retrieval, and effectively improving the overall ease of use.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-6 This utility model provides a hot-dip galvanizing pickling sealing device, including a tank body 3. A support plate 5 is provided on one side of the tank body 3. An electric telescopic rod 4 with its output end facing downward is fixed to the top of the support plate 5. A top plate 12 is fixed to the top of the tank body 3. A slot is opened on the side of the top plate 12, and a basket 9 is arranged in the slot. A cover plate 2 is hinged to the top of the basket 9. Multiple equally spaced openings 13 are opened on the bottom side wall of the basket 9. A protrusion 11 is fixed to the end of the basket 9 near the support plate 5. The output shaft end of the electric telescopic rod 4 is fixed to the side of the protrusion 11. An opening and closing assembly 1 is provided on the outside of the cover plate 2. In use, the electric telescopic rod 4 drives the basket 9 to rise, so that the opening and closing assembly 1 automatically opens the cover plate 2, thereby facilitating the placement of the workpiece to be pickled into the basket 9. Then, the output shaft of the electric telescopic rod 4 drives the basket 9 to move down into the pool 3. The cover 2 is automatically closed by the opening and closing assembly 1. The pool 3 contains a certain amount of pickling solution. The basket 9 is immersed in the pickling solution inside the pool 3, so that the pickling solution inside the pool 3 flows into the basket 9 through the opening 13, thereby immersing the workpiece inside the basket 9 in the pickling solution for pickling treatment. At this time, the top plate 12 and the cover 2 seal and cover the top of the pool 3, greatly reducing the evaporation and diffusion of the pickling solution inside the pool 3 into the surrounding environment, effectively reducing air pollution and effectively improving the protection of operators. The opening and closing assembly 1 realizes the automatic opening and closing of the cover 2, thereby eliminating the need for manual opening and closing of the cover 2, facilitating material feeding and unloading, and effectively improving the overall ease of use.

[0027] Further as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the opening and closing assembly 1 includes a pressure rod 101 fixed to the top of the support plate 5. The pressure rod 101 is located directly above the end of the cover plate 2 near the support plate 5. In actual operation, when the electric telescopic rod 4 drives the basket 9 to rise, the bottom end of the cover plate 2 and the pressure rod 101 come into contact. The bottom end of the pressure rod 101 contacts and presses the cover plate 2, causing the cover plate 2 to flip open, thereby opening the inside of the basket 9. This facilitates feeding and removing materials from the basket 9, realizing the automatic opening and closing of the cover plate 2. This eliminates the need for manual opening and closing of the cover plate 2, making it convenient for feeding and removing materials and effectively improving the overall ease of use.

[0028] Further as Figure 4 and Figure 5 As shown, it is worth noting that the bottom end of the pressure rod 101 is provided with an arc-shaped end 102; in actual operation, the arc-shaped end 102 effectively reduces the contact wear between the bottom end of the pressure rod 101 and the surface of the cover plate 2, thereby improving the service life of the components.

[0029] Further as Figure 4 , Figure 5 and Figure 6 As shown, it is worth noting that both ends of the cover plate 2 are fixed with joint shafts 103, and the two joint shafts 103 are arranged coaxially. The joint shafts 103 are located in the middle of the cover plate 2. A first protruding plate 104 is fixed to the side of the joint shaft 103, and a second protruding plate 106 is fixed to the outer wall of the basket 9. A spring 105 is arranged between the first protruding plate 104 and the second protruding plate 106, and the two ends of the spring 105 are fixed to the side of the first protruding plate 104 and the side of the second protruding plate 106, respectively. In actual operation, when the pressure... When rod 101 presses the cover plate 2 to flip open, the first convex plate 104 rotates toward the second convex plate 106, thereby compressing the spring 105. When the electric telescopic rod 4 moves the basket 9 down into the pool body 3, the cover plate 2 and the pressure rod 101 do not contact each other. At this time, the spring 105 restores its length and pushes the first convex plate 104 to reset. Thus, the first convex plate 104 and the connector shaft 103 drive the cover plate 2 to reset and close, realizing automatic closing. The elasticity of the spring 105 ensures the stability of the cover plate 2 when it is closed.

[0030] This solution has the following working process: During use, the electric telescopic rod 4 drives the basket 9 to rise, the cover plate 2 and the bottom end of the pressure rod 101 come into contact, and the bottom end of the pressure rod 101 contacts and presses the cover plate 2, causing the cover plate 2 to flip open, thereby opening the inside of the basket 9, which can easily place the workpiece to be pickled into the basket 9. After the workpiece is placed, the output shaft of the electric telescopic rod 4 drives the basket 9 to move down into the tank 3, the cover plate 2 and the pressure rod 101 no longer contact, at this time the spring 105 pushes the first The convex plate 104 is reset, thereby driving the cover plate 2 to reset and close automatically through the first convex plate 104 and the joint shaft 103. The basket 9 is immersed in the pickling solution inside the pool body 3, so that the pickling solution inside the pool body 3 flows into the basket 9 through the opening 13, so that the workpiece inside the basket 9 is immersed in the pickling solution for pickling treatment. At this time, the top plate 12 and the cover plate 2 seal and cover the top of the pool body 3 and the top of the basket 9, greatly reducing the evaporation and diffusion of the pickling solution inside the pool body 3 into the external environment.

[0031] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the bottom of the tank body 3 is fixed with an inlet pipe 6 and a drain pipe 7 that communicate with the inside of the tank body 3. Both the inlet pipe 6 and the drain pipe 7 are equipped with valves 8. In actual operation, by opening the valves 8, the pickling solution is introduced into the tank body 3 through the inlet pipe 6, and the pickling solution inside the tank body 3 is discharged through the drain pipe 7, which facilitates the replacement and replenishment of the pickling solution.

[0032] Further as Figure 1 As shown, it is worth noting that the bottom end of the support plate 5 is fixed with a base 14, and the top side of the base 14 has a plurality of symmetrically distributed screw holes 10. In actual operation, the support plate 5 is fixedly installed by installing bolts in the screw holes 10, thereby improving the support stability of the support plate 5.

[0033] In summary: The output shaft of the electric telescopic rod 4 drives the basket 9 to move down into the pool 3. The opening and closing assembly 1 automatically closes the cover 2. The pool 3 contains a certain amount of pickling solution. The basket 9 is immersed in the pickling solution inside the pool 3, allowing the pickling solution inside the pool 3 to flow into the basket 9 through the opening 13. This allows the workpiece inside the basket 9 to be immersed in the pickling solution for pickling treatment. At this time, the top plate 12 and the cover 2 seal and cover the top of the pool 3, greatly reducing the evaporation and diffusion of the pickling solution inside the pool 3 into the surrounding environment, effectively reducing air pollution and improving the protection of operators. The opening and closing assembly 1 realizes the automatic opening and closing of the cover 2, thus eliminating the need for manual opening and closing of the cover 2, facilitating material feeding and unloading, and effectively improving the overall ease of use.

[0034] The electric telescopic pole 4 can be purchased from the market. The electric telescopic pole 4 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the instruction manual.
