Description

Technical Field

[0001] The present invention relates to the technical field of galvanizing pots, and specifically to a closed heat-locking energy-saving galvanizing pot. Background Art

[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. The galvanizing pot is one of the main equipment for steel anti-corrosion treatment, and its structure usually varies according to application requirements and design differences. Hot-dip galvanizing in the galvanizing pot has the advantages of uniform coating, strong adhesion, and long service life. The fewer impurities in the zinc liquid composition, the better the fluidity of the zinc liquid.

[0003] In the production and processing of workpieces, a layer of zinc is often plated on the surface of the workpieces for aesthetics, rust prevention, etc. Hot-dip galvanizing is to first pickle the steel workpieces to remove the iron oxide on the surface of the steel workpieces. After pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution tank of ammonium chloride and zinc chloride, and then the workpiece is hoisted into the galvanizing pot for galvanizing operation.

[0004] There are still inconveniences in the prior art. During the galvanizing process of workpieces, the ceramic galvanizing pot for continuous galvanizing of workpieces only statically immerses the workpieces in the galvanizing pot, or only sets one spray head to galvanize the outer side of the workpieces. The opening of the galvanizing pot is exposed, and the zinc liquid exchanges heat with the outside air, resulting in heat loss of the zinc liquid and reduced galvanizing efficiency. In addition, there is a phenomenon that the corners of the workpieces are not galvanized, which requires secondary rework and will require more manpower and material resources, resulting in reduced galvanizing efficiency.

[0036] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment. This embodiment provides a closed heat-locking energy-saving galvanizing pot, as Figure 1 and Figure 2 shown, including: a pot body, the pot body has four surrounding side walls and a bottom wall, the four surrounding side walls are formed by four side wall steel plates enclosing a rectangular frame, the bottom wall is the bottom steel plate 13, and is welded to the bottom of the rectangular frame to form a galvanizing cavity for storing galvanizing liquid. Specifically, as Figure 6 and Figure 7 shown, the side wall steel plates include a protective steel plate 1, a heat insulation layer 17 and a ceramic heat insulation board 14. The outermost side of the rectangular frame is the protective steel plate 1, the innermost side of the rectangular frame is the ceramic heat insulation board 14, the four protective steel plates 1 are welded together after surrounding, and then the heat insulation layer 17 is filled between the ceramic heat insulation board and the protective steel plate 1. The ceramic heat insulation board 14 is used as a heat insulation structure in the galvanizing cavity, and cooperating with the heat insulation layer 17 is beneficial to the heat preservation of the galvanizing liquid in the galvanizing cavity. The heat insulation layer 17 can be made of heavy-duty refractory clay bricks or asbestos boards with a corrugated structure, which has good high-temperature resistance and heat insulation performance.

[0038] It should be noted that the pot body is embedded in the workshop floor, and the upper opening of the rectangular frame is higher than the ground to prevent small particle impurities from randomly falling into the pot body. Moreover, the shape and size of the pot body are determined according to the requirements of the galvanizing process. Common pot body shapes include rectangular, square, circular, etc.

[0039] As Figure 6 shown, a heater 3 for heating the galvanizing solution is built into the bottom steel plate 13. The heater 3 is used to heat the zinc solution to the required temperature. The type and position of the heater 3 are determined according to the design of the galvanizing pot. Common heaters 3 include resistance heaters or induction heaters. Temperature control system: used to monitor and control the temperature of the zinc solution. Usually, a temperature control system is also provided, including a temperature sensor, a controller, and an actuator. A groove is provided on the upper end face of the bottom steel plate 13, and the temperature sensor can be embedded in the groove to avoid being damaged by the workpiece. The sensor is used to monitor the temperature of the zinc solution in real time. The controller adjusts the heater 3 according to the preset temperature range, and the actuator is responsible for executing the instructions of the controller to adjust the temperature of the zinc solution. The temperature of the zinc solution is strictly controlled to keep it in a molten state. Usually, the temperature of the zinc solution is about 450 °C.

[0040] At the same time, a movable support plate 2 is also disclosed. As Figure 2 and Figure 3 shown, a cover 21 is adjustably provided on the movable support plate 2. Guide seats 26 are fixed at both ends of the upper end of the movable support plate 2. Lifting insertion holes are provided in the guide seats 26. Sliders 27 are fixedly extended at both ends of the cover 21, and the sliders 27 are slidably inserted into the lifting insertion holes. A notch is provided on one side of the hollow support table 11. A support roller 16 is rotatably provided between the opposite side walls in the notch. An inclined sliding surface is provided on one side wall of the cover 21 facing the support roller 16. A hollow support table 11 is provided at the upper end of the rectangular frame to block the galvanizing cavity and store the galvanizing solution in a closed cavity.

[0041] Specifically, during galvanizing, the workpiece to be galvanized is placed into the galvanizing cavity. The movable support plate 2 is slidably seated on the upper end face of the hollow support table 11 on the rectangular frame. The cover 21 drops to cover the hollow support table 11. The inclined sliding surface of the cover 21 rolls along the outer wall of the support roller 16. At the same time, the sliders 27 at both ends of the cover 21 slide along the lifting insertion holes, and the height drops to block the opening of the galvanizing cavity. In this way, the closed path for heat exchange between the high-temperature galvanizing solution in the galvanizing cavity and the external air is disconnected to prevent a large amount of heat loss of the galvanizing solution.

[0042] After galvanizing is completed and the workpiece needs to be taken out, as Figure 5 and Figure 6 shown, along the upper end face of the hollow support table 11 along Figure 6Pushing the movable support plate 2 horizontally in the direction shown by the arrow T1 can drive the inclined sliding surface of the cover 21 to roll along the outer wall of the support roller 16. At the same time, the sliders 27 at both ends of the cover 21 slide along the lifting jacks, that is, along Figure 6 the direction shown by the arrow T, the height of the cover 21 rises, disengaging from the opening of the galvanizing chamber, so as to facilitate fishing for the galvanized workpieces.

[0043] In order to reduce the resistance during the adjustment of the movable support plate 2, as Figure 2 shown, a plurality of inverted L-shaped support rods 23 are fixed on one side wall of the movable support plate 2. A longitudinal support rod 25 is fixed at one end of the bottom wall of the movable support plate 2 away from the inverted L-shaped support rods 23. Roller wheels 24 are rotatably provided at the bottom ends of the inverted L-shaped support rods 23 and the longitudinal support rod 25; the roller wheels 24 connected to the inverted L-shaped support rods 23 roll on the ground, and a rolling groove 12 for sliding and engaging with the roller wheels 24 connected to the longitudinal support rod 25 is provided at the upper edge side of the hollow support table 11. The inverted L-shaped support rods 23 and the longitudinal support rod 25 support the movable support plate 2 to ensure that the movable support plate 2 is flush with the upper end surface of the hollow support table 11. When adjusting the movable support plate 2, pushing the movable support plate 2 horizontally can cause the roller wheels 24 at the bottom ends of the plurality of inverted L-shaped support rods 23 to roll horizontally along the ground, and at the same time, the roller wheels 24 connected to the longitudinal support rod 25 roll horizontally along the rolling groove 12, smoothly adjusting the movable support plate 2 and reducing the resistance during the adjustment of the movable support plate 2.

[0044] In addition, attention should be paid to the speed at which the loading plate 4 descends into the pot. First of all, the speed at which the workpieces are put into the pot should be determined according to their size, shape and material. Usually, the workpieces are slowly put into the pot to prevent the zinc liquid from splashing out or the surface of the workpieces from being damaged. For large or complex workpieces, the descending speed may need to be slower to ensure that they smoothly enter the zinc liquid. In addition, the angle at which the workpieces are put into the pot is also crucial. Long workpieces should be inclined into the pot at an angle not less than 30 degrees to ensure that the workpieces can smoothly enter the zinc liquid and avoid collisions. For workpieces with irregular shapes, the descending angle needs to be adjusted to adapt to their shapes.

[0045] In this embodiment, a plurality of air supply holes are also provided on the cover 21. The upper openings of the air supply holes are connected with butt joint pipes 22, and the butt joint pipes 22 are connected with air pipes, and the air pipes can be butted with the air outlet 42 of an external high-pressure air pump, as Figure 4 and Figure 5 shown. Using the high-pressure air pump to provide high-pressure gas, high-pressure gas is provided for each air supply hole through the air pipe and is led out from the bottom openings of the air supply holes and enters the galvanizing chamber.

[0046] At the same time, a loading member is also disclosed, as Figure 8 and Figure 9As shown in the figure, the material carrier includes a material carrying plate 4. Both ends of the material carrying plate 4 are bent upward to form hoisting plates, and hanging holes are provided at the upper corners of the hoisting plates. The upper end surface of the material carrying plate 4 serves as the supporting surface for supporting the workpiece. Lifting ropes are used to connect the hooks and are respectively hung in the hanging holes of the two hoisting plates. The material carrying plate 4 with the workpiece placed thereon is hoisted and sunk into the galvanizing cavity by using a hoisting device, and it is ensured that the liquid level height of the galvanizing liquid is higher than the height of the workpiece to ensure that the workpiece is completely immersed below the liquid level of the galvanizing liquid, so as to avoid ungalvanized positions and the need for rework.

[0047] In addition, the material carrier further includes a plurality of baffle plates. Each baffle plate includes two partition plates 41. A plug 43 is fixed to the bottom wall of the partition plate 41. A slot 44 for inserting the plug 43 is provided on the upper end surface of the material carrying plate 4. Both side edges of the two partition plates 41 are bent to form extension parts. The extension parts on both sides of the two partition plates 41 are attached to form a plate body with a hollow structure. An exhaust port 42 is provided at the bottom end of the side wall of the partition plate 41. An exhaust port 42 is also provided at the upper end of the side wall of the partition plate 41. As Figure 8 and Figure 10 shown in the figure, the upper opening of the hollow structure of the plate body is aligned and attached to the lower opening of the air supply hole. At the same time, the plugs 43 of the two partition plates 41 are respectively inserted into the corresponding slots 44, so as to ensure that the baffle plate stands vertically on the upper end surface of the material carrying plate 4, and there is a gap between adjacent baffle plates, and this gap serves as the workpiece storage space.

[0048] It should be further noted that after the baffle plate is vertically arranged on the upper end surface of the material carrying plate 4, the upper opening of the hollow structure between the two partition plates 41 can contact the bottom wall of the cover 21 covering the opening of the galvanizing cavity. At the same time, the opening of the air supply hole is also aligned and attached to the upper opening of the hollow structure. In this way, the high-pressure gas led out from the bottom opening of the air supply hole is completely introduced into the hollow structure and blown out from a row of multiple exhaust ports 42 located on the lower side, which can blow the bottom galvanizing liquid to achieve a turbulence operation, thereby driving the galvanizing liquid to flow in the galvanizing cavity and accelerating the flow speed of the galvanizing liquid on the surface of the workpiece to ensure the smooth galvanizing of the workpiece surface. The row of multiple exhaust ports 42 on the upper side is used to dredge the waves generated after the turbulence of the galvanizing liquid. At the same time, the opening of the row of exhaust ports 42 on the upper side is smaller than the opening of the row of exhaust ports 42 on the lower side to prevent the waves from splashing onto the bottom wall of the cover 21 after hitting the upper side wall of the partition plate 41, resulting in a large amount of galvanizing liquid droplets remaining on the bottom wall of the cover 21. When the cover 21 is finally opened, a large amount of galvanizing liquid drips onto the upper end surface of the hollow support platform 11, which requires manual cleaning and also causes waste of the galvanizing liquid.

[0049] In addition to the method of arranging a row of exhaust ports 42 at both the upper and lower ends of the side wall of the partition plate 41, it is also possible to select to provide a turning notch at the upper end of the side wall of the partition plate 41, and a flow buffer plate 45 is rotatably provided in the turning notch, and a torsion spring is provided at the rotation point. As Figure 11As shown, after the waves generated by the galvanized liquid turbulence are dredged and flow, they will impact the flow retarder plate 45 in the turnover notch. After being impacted, the flow retarder plate 45 will turn around the rotation position to relieve the impact force of the galvanized liquid. This is also to prevent the waves from splashing onto the bottom wall of the cover 21 after impacting the upper side wall of the partition plate 41, resulting in a large amount of galvanized liquid droplets remaining on the bottom wall of the cover 21. When the cover 21 is finally opened, a large amount of galvanized liquid will drip onto the upper surface of the hollow support platform 11, which requires manual cleaning and causes waste of the galvanized liquid.

[0050] In this embodiment, further, as Figure 3 shown, a plurality of longitudinally distributed anti-collision strips 15 are provided on the outer walls of the ceramic heat insulation plates 14 around the galvanizing cavity. By providing a circle of anti-collision strips 15 on the side walls around the galvanizing cavity, it is possible to prevent the side wall of the loading plate 4 from colliding with the ceramic heat insulation plate 14 when the loading plate 4 is lowered, causing damage to the ceramic heat insulation plate 14.

[0051] In summary, by providing a turbulent flow air flow in the galvanized liquid, the zinc liquid can be disturbed, causing the zinc liquid in the galvanizing pot to flow rapidly on the surface of the workpiece, making the plated finished product smooth. In addition, during the galvanizing process, the galvanizing operation can be carried out in a relatively closed environment, disconnecting the closed path of heat exchange between the high-temperature galvanized liquid in the galvanizing cavity and the external air, thereby reducing the large loss of heat of the galvanized liquid and improving the galvanizing efficiency.

[0052] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
