[0001] The utility model relates to the technical field of galvanizing, and more specifically to a hot-dip galvanizing device with uniform galvanizing. Background Art

[0002] Galvanizing protects steel from oxidation and rust by depositing a zinc coating on it. This layer effectively isolates the steel from air and moisture, slowing the corrosion process. This physical protection method is more durable than coatings or spray coatings and is particularly suitable for highly corrosive environments.

[0003] For example, the utility model with patent publication number CN221217890U discloses a hot-dip galvanizing device for iron accessories, including a galvanizing pool, a side plate is provided on one side of the galvanizing pool, a lifting motor is provided at the upper end of the side plate, a lifting screw is provided at the lower end of the lifting motor, a driving frame is threadedly connected to the surface of the lifting screw, a fixed plate is provided at the lower end of the driving frame, a plurality of hooks are provided at the bottom of the fixed plate, a spacing adjustment component is provided between the fixed plate and the hook, and a zinc layer cleaning component is provided inside the galvanizing pool.

[0004] When the hot-dip galvanizing device of the related technology is used, although it can clean the zinc layer condensed on the surface of the galvanizing pool, the cleaning of the zinc layer only achieves a simple gathering effect, because the zinc layer is still in the galvanizing pool, which greatly increases the difficulty of subsequent cleaning of the zinc layer; in addition, because the cleaning module is relatively single and the mobile cleaning cycle is long, the efficiency of zinc layer cleaning is greatly reduced. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution that can solve the problems of incomplete and inefficient cleaning of the zinc layer in the galvanizing pool.

[0006] To achieve the above object, the utility model provides the following technical solution: a hot-dip galvanizing device for uniform galvanizing, comprising a hot-dip galvanizing pool, an electric heating plate provided on the hot-dip galvanizing pool, an extension pool provided on the top edge of the hot-dip galvanizing pool, a baffle provided on the inner wall of the extension pool, and a filter provided between the baffle and the extension pool;

[0007] The hot-dip galvanizing pool is provided with a driving unit, the driving unit is provided with a hydraulic rod, the hydraulic rod is provided with a cleaning plate, the cleaning plate is located on the inner side of the hot-dip galvanizing pool, and a displacement detection unit is provided between the driving unit and the hot-dip galvanizing pool.

[0008] In a preferred embodiment, a through groove is provided on the baffle, an impurity treatment area is formed between the baffle and the extension pool, the filter is located in the impurity treatment area, and the impurity treatment area is divided into an impurity collection area and a galvanizing liquid recovery area above and below the filter.

[0009] In a preferred embodiment, a gate is plugged into the extension pool, and the gate is located on one side of the impurity collection area.

[0010] In a preferred embodiment, the drive unit includes a servo motor, which is fixedly connected to the side of the hot-dip galvanizing pool. The output shaft of the servo motor is fixedly connected to a bidirectional screw rod, and a pair of movable seats are threadedly connected to the bidirectional screw rod. The hydraulic rod is fixedly connected to the movable seat.

[0011] In a preferred embodiment, the output end of the hydraulic rod is bolted to a bracket, and the cleaning plate is fixedly connected to one end of the bracket.

[0012] In a preferred embodiment, a buffer groove is provided on the cleaning plate.

[0013] In a preferred embodiment, the displacement detection unit includes a laser displacement sensor and a laser reflector. The laser displacement sensor is fixedly connected to the movable seat, and the laser reflector is fixedly connected to the side of the hot-dip galvanizing pool. The laser displacement sensor and the laser reflector are horizontally arranged.

[0014] The technical effects and advantages of this utility model are:

[0015] 1. The hot-dip galvanizing device with uniform galvanizing is driven by a driving unit to move a cleaning plate in the hot-dip galvanizing pool. The cleaning plate can gather and transfer the condensed zinc layer in the hot-dip galvanizing pool. The height of the cleaning plate is adjusted by a hydraulic rod. The position of the filter screen provides an impurity collection area for the zinc layer and a galvanizing liquid recovery area. In this way, the cleaning plate can easily transfer the collection position of the zinc layer and reduce the residual zinc layer in the hot-dip galvanizing pool.

[0016] 2. The hot-dip galvanizing device with uniform galvanizing is provided with a pair of cleaning plates. The driving unit can drive the pair of cleaning plates to perform opposite cleaning movements, which can shorten the cleaning time of the zinc layer and improve the cleaning efficiency.

[0024] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 The utility model provides a hot-dip galvanizing device with uniform galvanizing, which includes a hot-dip galvanizing pool 1 on which an electric heating plate 2 is arranged.

[0026] In the utility model, a heating interlayer is provided in the hot-dip galvanizing pool 1, and the electric heating plate 2 can be buried in the heating interlayer. In the present application, multiple electric heating plates 2 can be provided, and the electric heating plates 2 can be electrically connected to the existing temperature controller through existing technology, so that the electric heating plates 2 can heat the galvanizing liquid in the hot-dip galvanizing pool 1. Multiple electric heating plates 2 can be distributed in multiple directions of the hot-dip galvanizing pool 1, which can ensure the uniformity of the heating temperature. The uniformity of the galvanizing liquid temperature can ensure the uniform galvanizing of steel products.

[0027] In this embodiment, an extension pool 3 is provided at the top edge of the hot-dip galvanizing pool 1 .

[0028] In the present invention, the extension pool 3 can be integrated with the hot-dip galvanizing pool 1. There are two groups of extension pools 3, and the extension pools 3 are arranged on both sides of the length direction of the hot-dip galvanizing pool 1. The extension pools 3 are arranged to increase the capacity of the hot-dip galvanizing pool 1.

[0029] In this embodiment, a baffle 4 is provided on the inner wall of the extension pool 3 , and a filter screen 5 is provided between the baffle 4 and the extension pool 3 .

[0030] The baffle 4 is arranged in a triangular structure. The inclined surface of the baffle 4 can provide a sliding surface. The sliding surface enables the subsequent zinc layer to slide with a height change using a cleaning structure. The filter screen 5 can be fixed between the baffle 4 and the extension pool 3. The filter screen 5 can filter the zinc layer and the galvanizing solution.

[0031] In this embodiment, a through groove 12 is provided on the baffle 4, and an impurity treatment area is formed between the baffle 4 and the extension pool 3. The filter screen 5 is located in the impurity treatment area, and the impurity treatment area is divided into an impurity collection area and a galvanizing liquid recovery area above and below the filter screen 5.

[0032] When galvanizing steel products, the height of the galvanizing liquid in the hot-dip galvanizing pool 1 is also higher than the through groove 12 and lower than the position of the filter 5. When the zinc layer cleaning structure pushes the zinc layer into the impurity treatment area, the zinc layer and a small amount of galvanizing liquid will enter the impurity treatment area simultaneously. Since the filter 5 has a porous structure, the filter 5 can filter the zinc layer on the surface of the filter 5, and the galvanizing liquid can be filtered into the galvanizing liquid recovery area. Then the galvanizing liquid can flow back to the hot-dip galvanizing pool 1 through the through groove 12. This method of cleaning the zinc layer can reduce the residue of the condensed zinc layer in the hot-dip galvanizing pool 1, thereby ensuring the quality of galvanizing of steel products.

[0033] In this embodiment, a gate plate 13 is plugged into the extension pool 3 , and the gate plate 13 is located at one side of the impurity collection area.

[0034] A slot for inserting the gate plate 13 is provided on the extension pool 3, and the gate plate 13 has a protrusion around it, so that the gate plate 13 can be flexibly sealed in the slot through the protrusion. Since the slot corresponds to one side of the impurity collection area, the gate plate 13 can prevent the zinc layer from overflowing at the slot position, and the slot can be used as a channel for discharging the zinc layer. When the zinc layer on the filter screen 5 needs to be further cleaned, the user can use a scraper tool to discharge the zinc layer on the filter screen 5 through the slot position.

[0035] In this embodiment: a driving unit is provided on the hot-dip galvanizing pool 1, and the driving unit includes a servo motor 6, which is fixedly connected to the side of the hot-dip galvanizing pool 1. The output shaft of the servo motor 6 is fixedly connected to a bidirectional screw rod 7, and a pair of movable seats 8 are threadedly connected to the bidirectional screw rod 7.

[0036] The number of drive units in the present invention is two groups, and the two groups of drive units are respectively arranged at the front and rear ends of the hot-dip galvanizing pool 1. The servo motor 6 can be fixedly mounted on the hot-dip galvanizing pool 1 through a motor seat. In order to ensure the stable rotation of the bidirectional screw rod 7, at least three bearing seats can be fixed on the side of the hot-dip galvanizing pool 1 to provide rotation support for the bidirectional screw rod 7. When the servo motor 6 is started, the bidirectional reciprocating thread on the bidirectional screw rod 7 is used, so that a pair of moving seats 8 can be driven on the bidirectional screw rod 7 to achieve movement towards or away from each other.

[0037] In this embodiment: a hydraulic rod 10 is provided on the driving unit, the hydraulic rod 10 is fixedly connected to the moving seat 8, a cleaning plate 11 is provided on the hydraulic rod 10, the cleaning plate 11 is located on the inner side of the hot-dip galvanizing pool 1, the output end of the hydraulic rod 10 is bolted to a bracket 14, and the cleaning plate 11 is fixedly connected to one end of the bracket 14.

[0038] The hydraulic rod 10 can be fixedly mounted on the movable seat 8 through the cylinder seat. The number of the cleaning plates 11 is a pair, and the cleaning plates 11 are arranged along the length direction of the hot-dip galvanizing pool 1. The pair of cleaning plates 11 located in the hot-dip galvanizing pool 1 are arranged in an inner eight shape, so that the cleaning plates 11 push one side of the zinc layer to promote the falling of the zinc layer. The cleaning plates 11 are bolted to the hydraulic rod 10 through the bracket 14 and can be easily disassembled and assembled.

[0039] When a pair of movable seats 8 move away from each other, the movable seat 8 can drive the cleaning plate 11 partially immersed in the galvanizing solution to move in the hot-dip galvanizing pool 1 toward the extension pool 3 through the hydraulic rod 10 until the cleaning plate 11 is close to the baffle 4. At this time, the piston of the hydraulic rod 10 is extended and the height of the cleaning plate 11 can be adjusted through the bracket 14, so that the cleaning plate 11 can slide under the baffle 4 and push the zinc layer on the side of the cleaning plate 11 through the baffle 4 onto the filter screen 5. This can reduce the residual zinc layer in the hot-dip galvanizing pool 1. When the cleaning plate 11 cleans the zinc layer again, the return stroke of the cleaning plate 11 does not contact the galvanizing solution until a pair of cleaning plates 11 are close to each other. At this time, the hydraulic rod 10 can control the corresponding cleaning plate 11 to descend to the midpoint of the hot-dip galvanizing pool 1 and immerse it in the galvanizing solution, so that the cleaning plate 11 can continue to gather and push the zinc layer.

[0040] In this embodiment, a buffer groove 15 is provided on the cleaning plate 11 .

[0041] The provision of the buffer tank 15 can reduce the movement resistance of the cleaning plate 11 in the galvanizing solution, thereby reducing the phenomenon of galvanizing solution surge.

[0042] In this embodiment: a displacement detection unit is provided between the driving unit and the hot-dip galvanizing pool 1, and the displacement detection unit includes a laser displacement sensor 9 and a laser reflector 91. The laser displacement sensor 9 is fixedly connected to the movable seat 8, and the laser reflector 91 is fixedly connected to the side of the hot-dip galvanizing pool 1. The laser displacement sensor 9 and the laser reflector 91 are arranged horizontally.

[0043] In the present invention, two groups of displacement detection units can be provided, and the two groups of displacement detection units are respectively used to detect the working positions of the two groups of movable seats 8. The laser displacement sensor 9 of the prior art adopts the echo analysis principle to measure the distance to achieve a certain degree of accuracy. The laser displacement sensor 9 of the prior art is internally composed of a processor unit, an echo processing unit, a laser transmitter, a laser receiver and other parts. The working principle of the laser displacement sensor 9 is: the laser transmitter shoots a visible red laser through a lens to the surface of the object to be measured. The laser reflected by the object passes through the receiver lens and is received by the internal CCD linear camera. Depending on the distance, the CCD linear camera can see this light spot at different angles. According to this angle and the known distance between the laser and the camera, the digital signal processor can calculate the distance between the sensor and the object to be measured.

[0044] When in use, the servo motor 6 can drive the bidirectional screw 7 to rotate, and the rotation of the bidirectional screw 7 can drive a pair of moving seats 8 to move closer to or away from each other. When the moving seat 8 moves, it can drive the laser light-emitting sheet 91 thereon to move, so that the laser emitted by the laser displacement sensor 9 can be reflected by the laser light-emitting sheet 91 and then received by the laser displacement sensor 9, so that the moving distance of the moving seat 8 can be monitored. When a pair of cleaning plates 11 approach each other, the default distance between the cleaning plate 11 and the laser displacement sensor 9 is one meter, so the hydraulic rod 10 piston is driven to control the cleaning plate 11 to descend until the cleaning plate 11 is cleaned. The plate 11 is partially immersed in the galvanizing solution, and when the distance between the cleaning plate 11 and the laser displacement sensor 9 is 0.1 meter, the hydraulic rod 10 piston is driven to control the cleaning plate 11 to rise, so that the cleaning plate 11 that moves horizontally and rises can slide on the inclined surface of the baffle 4. The slope of the inclined surface is designed to match the driving speed of the servo motor 6 and the contraction speed of the hydraulic rod 10, so as to ensure that the zinc layer pushed by the cleaning plate 11 can move up on the inclined surface of the baffle 4. After the cleaning plate 11 is located at the top of the baffle 4, the cleaning plate 11 stops moving, so that the zinc layer on one side of the cleaning plate 11 can be pushed onto the filter 5.

[0045] When the cleaning plate 11 needs to clean the zinc layer again, the cleaning plate 11 moves in the opposite direction. The cleaning plate 11 that moves in the opposite direction is suspended above the galvanizing liquid until a pair of cleaning plates 11 approach each other, that is, the distance between the cleaning plate 11 and the laser displacement sensor 9 is one meter. Then, the cleaning plate 11 can be lowered and partially immersed in the galvanizing liquid to push the zinc layer.

[0046] It is worth noting that the electrical components such as the electric heating plate 2, servo motor 6, laser displacement sensor 9 and hydraulic rod 10 appearing in the present invention are all electrically connected to the main controller and the power supply. The main controller can obtain the control circuit through simple programming by technicians in this field. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology will not be repeated in this article.
