Description

Technical Field

[0001] The utility model belongs to the technical field of galvanizing drying, in particular to a galvanizing drying device. Background Technique

[0002] Galvanizing refers to a surface treatment technology in which a layer of zinc is plated on the surface of metals, alloys or other materials for purposes such as aesthetics and rust prevention. The main method used is hot-dip galvanizing. The components after galvanizing treatment not only have aesthetics but also have a rust prevention effect. Before the components are galvanized, their surfaces are cleaned to remove impurities. After the cleaning of the components, their surfaces need to be dried. On the one hand, the moisture on the surface of the components is dried to prevent splashing of zinc and injury to people during galvanizing of the components. On the other hand, the temperature of the components is increased to avoid taking away the heat energy in the zinc pot. Traditionally, a box is used to dry small components. The traditional box is only dried by heating, with a single function and low drying efficiency.

[0003] A drying device for hot-dip galvanizing production of steel components with the publication number of CN220959344U magnetically adsorbs and fixes the steel components through the magnetism of a conduction electromagnet. When drying the steel components, the electric heating wire raises the temperature inside the box, and the air inlet component and the air outlet component promote the air flow inside the box to improve the drying efficiency. The magnetic conduction column reduces the contact area with the steel components and increases the contact area between the steel components and the air flow. Moreover, the driving motor drives the steel components to rotate through the bearing mechanism, throws off the moisture on their surfaces, reduces the moisture residue on the surface of the steel components, and improves the drying efficiency. However, the throwing off of moisture easily causes collisions, resulting in damage to the galvanized layer and is not applicable to all components. For this point, another drying device with high uniformity is designed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a galvanizing drying device to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A galvanizing drying device includes at least one drying cylinder. The top of the drying cylinder is open, and a closing cover for sealing is arranged at the open part. A circulation cover is arranged at the center of the inner circumference of the drying cylinder, and the bottom of the circulation cover is hollow and open. A gap is provided between the bottom of the circulation cover and the inner bottom of the drying cylinder, and an air guiding component is arranged at the bottom end of the circulation cover. A plurality of circulation holes are opened on the side wall of the circulation cover, and a hanging component for conveniently placing components is arranged on the inner circumference of the circulation cover. A plurality of heating components for generating heat are installed on the inner wall part of the drying cylinder.

[0006] In a further embodiment, a concave-convex structure is provided between the bottom of the closing cover and the top of the drying cylinder to facilitate clamping for sealing.

[0007] In a further embodiment, a lifting member is installed at the bottom of the closing cover, and the lifting member is connected to the top end of the suspension member.

[0008] In a further embodiment, a bottom plate is provided at the bottom of the drying cylinder, and a top plate is provided at the top of the closing cover.

[0009] In a further embodiment, two grooves are formed on one side of the top of the bottom plate, and a displacement screw base and a displacement screw are arranged on the inner circumference of the grooves.

[0010] In a further embodiment, both ends of the displacement screw are respectively rotatably connected to the ends of the groove, and the outer circumference of the displacement screw is threadedly sleeved with the displacement screw base.

[0011] In a further embodiment, the outer circumference of the displacement screw base is adapted to the inner circumference of the groove to form a limit, and a pulling support rod is hinged between the top of the displacement screw base and the bottom of the top plate.

[0012] In a further embodiment, the two pulling support rods are symmetrically distributed, and a motor for driving is provided at the end of the displacement screw.

[0013] In a further embodiment, guide columns are provided at the two corners of the bottom plate and the top plate away from the displacement screw.

[0014] In a further embodiment, a detachable side plate is provided at the part of the drying cylinder close to the heating member.

[0015] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0016] The hollow design inside the circulation hood and the gap between the bottom of the circulation hood and the drying cylinder can produce a wind flow guiding effect. When the air guiding component installed at the bottom of the circulation hood operates, it exhausts air in a direction away from the circulation hood, creating a negative pressure inside the circulation hood. Combined with the multiple evenly distributed circulation holes on the side wall of the circulation hood, an intake air flow is generated. When intake air passes through the heating area, heat will be brought in, thereby achieving uniform drying. Further, the connection between the lifting member and the suspension part, and the lifting operation of the lifting member can achieve height displacement, further improving the drying uniformity;

[0017] For this galvanized drying device, through the generation of positive and negative pressures inside, it enables the heat wind to evenly enter the components to be dried, making the drying more uniform. Description of the Drawings

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0026] Unless otherwise defined, the up, down, left, right, front, back, inner, and outer directions involved herein are based on the up, down, left, right, front, back, inner, and outer directions in the drawings shown in the present invention, and are hereby explained together.

[0027] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., according to actual needs.

[0028] Please refer to Figures 1 to 4 , the galvanized drying device, including a bottom plate 10 and a plurality of drying cylinders 1 above the bottom plate 10. The bottom of the drying cylinder 1 is fixed to the top of the bottom plate 10 to prevent the drying cylinder 1 from shifting. A top plate 11 is provided above the drying cylinder 1, and the top plate 11 is fixed to a plurality of closing covers 2;

[0029] The top of the drying cylinder 1 is open, and a closing cover 2 is installed at the opening part. The bottom edges of both the closing cover 2 and the top edge of the drying cylinder 1 are provided with concave-convex designs to achieve the function of clamping, and a rubber layer can also be adhered to the concave-convex parts for strengthening sealing. A plurality of heating elements 7 are adhered to the inner wall of the drying cylinder 1, and the heating elements 7 are used to generate heat for drying;

[0030] To facilitate the placement of components, a hanging component 3 is arranged at the center of the inner circumference of the drying cylinder 1. The hanging component 3 can be a structure of a main and auxiliary bracket or a single hook, etc., and can be freely selected according to the situation.

[0031] Please refer to Figure 1 and Figure 2 As shown in, in order to achieve automatic opening and closing, two grooves are provided on one side of the top of the bottom plate 10. A displacement screw base 13 and a displacement screw 12 are arranged on the inner circumference of the grooves. A driving motor can be installed at the end of the displacement screw 12. The driving motor can be embedded and installed at the central position or the side position, and the surface is then covered by a maintenance cover. When maintenance is required, the maintenance cover can be removed for maintenance;

[0032] The displacement screw base 13 is threadedly sleeved on the outer circumference of the displacement screw 12. The outer circumference of the displacement screw base 13 is adapted to the grooves, thereby realizing the anti-rotation limit. The two ends of the displacement screw 12 are respectively rotatably connected to the ends of the grooves. A pulling support rod 14 is hinged between the top of the displacement screw base 13 and the bottom of the top plate 11. The two pulling support rods 14 are symmetrically distributed. Guide columns 15 are provided at the two corners of the parts of the bottom plate 10 and the top plate 11 away from the displacement screw 12;

[0033] To further improve the uniformity, a lifting member 9 is installed at the bottom of the closing cover 2, and the lifting member 9 is connected to the top end position of the hanging component 3.

[0034] It should be noted that since the lengths of the two pulling support rods 14 are fixed and symmetrically distributed, an isosceles trapezoid structure is formed. Further, a virtual vertical line is drawn on both sides of the trapezoid, that is, both sides are the same right-angled triangles. Thus, due to the stability of the triangle, when the displacement screw bases 13 on both sides move, that is, the two pulling support rods 14 will also move according to the same law, thereby realizing the lifting function.

[0035] Please refer to Figure 1 and Figure 3, in order to achieve uniform drying, a circulation hood 4 is provided at the inner peripheral center of the drying cylinder 1. The bottom of the circulation hood 4 is a hollow opening. There is a gap between the bottom of the circulation hood 4 and the inner bottom of the drying cylinder 1. An air guiding component 5 is provided at the bottom end of the circulation hood 4. The air guiding component 5 can be an exhaust fan or an exhaust blower, etc. The outer periphery of the air guiding component 5 is connected to the inner wall of the circulation hood 4 through an annular fixing ring 8, and at the same time, the edge is sealed. A plurality of circulation holes 6 are provided on the side wall of the circulation hood 4.

[0036] The above components and electrical equipment are all prior art or currently achievable technologies. Their working principles, dimensions, and models have nothing to do with the functions of this application, so no more description will be given, and they are all controlled by a remote control switch.

[0037] Working principle

[0038] When using this galvanizing drying device, place the components on the hanging component 3, start the driving motor, drive the two displacement screws 12 to rotate synchronously, make the displacement screw seats 13 move away from each other synchronously, so that the top plate 11 descends, and further make the closing cover 2 engage with the drying cylinder 1;

[0039] Start the heating element 7 to generate heat. At the same time, start the air guiding component 5 to drive the air inside the suction circulation hood 4 to be transported to the outer wall part of the circulation hood 4, thereby generating negative pressure. At the same time, the air outside the circulation hood 4 carries the generated heat and is transported into the circulation hood 4 through the circulation holes 6;

[0040] Due to the uniform distribution of the multiple circulation holes 6, uniform blowing towards the components and uniform drying are achieved;

[0041] Start the lifting component 9 during drying. The operation of the lifting component 9 drives the suspended part to move up and down reciprocally, further improving the uniformity.

[0042] It should be noted that in this article, relational terms such as "one" and "two" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to this process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
