Description
Technical Field
[0001] The utility model relates to the technical field of hot-dip galvanizing, in particular to a hot-dip galvanizing protection mechanism. Background Art
[0002] Hot-dip galvanizing is an anti-corrosion treatment process primarily used to protect steel. The process involves immersing steel in molten zinc to form a zinc coating. This coating effectively blocks air and moisture, preventing rust and corrosion. A Chinese patent application (Granted Publication No. CNU) discloses a hot-dip galvanizing protection mechanism comprising a galvanizing bath. The bath is equipped with a cage fixedly connected to a boom, which is then fixedly connected to a steel wire rope. Fixed plates are symmetrically fixedly connected to the inner wall of the bath, rotatably connected to a shaft, and a drive wheel is fixedly inserted through the shaft. A drive mechanism is symmetrically installed on the inner wall of the bath. Drive belts are attached to the drive wheels, and first and second fixed sleeves are fixedly connected to the drive belts, respectively. Both the first and second fixed sleeves are connected to cover plates via fixed rods. During galvanizing, a drive motor drives the drive wheels to rotate, thereby moving the drive belts. The first and second fixed sleeves drive the two cover plates toward each other until they close. The cover plates engage with the annular sealing plate, sealing the bath opening.
[0003] The technical solution of the above patent achieves a sealing effect on the galvanizing pool. However, its various structures are placed inside the galvanizing pool and are transmitted by a transmission belt. Since the temperature in the galvanizing pool is relatively high and the waste gas generated by galvanizing is also corrosive, it will seriously affect the service life of each component. Based on this, the solution is further improved. Summary of the Invention

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications. Example
[0023] See also Figures 1 to 5 In this embodiment, a hot-dip galvanizing protection mechanism is provided, including a galvanizing pool 1. Two sealing plates 2 are provided at the upper end of the galvanizing pool 1. The two sealing plates 2 can move away from or towards each other, so that when the material is galvanized, the two sealing plates 2 are close to each other and sealed to prevent exhaust gas from escaping. Conversely, when the material is placed in the galvanizing pool 1 or taken out of the galvanizing pool 1, the two sealing plates 2 are moved away from each other to facilitate the removal of the material.
[0024] The sealing plate 2 is slidably connected to the upper side wall of the galvanizing pool 1. At the same time, a limiting plate 3 is symmetrically provided on the upper part of the galvanizing pool 1. Two limiting plates 3 are provided on each side. The limiting plates 3 on the same side are symmetrically arranged front and back about the galvanizing pool 1. The limiting plate 3 is an inverted L-shape, which can limit the sealing plate 2. It is also slidably connected to the sealing plate 2, so that the limiting plate 3 can only move left and right in the horizontal direction, thereby ensuring the sealing effect of the sealing plate 2 on the galvanizing pool 1;
[0025] A moving component 4 is provided on one of the limiting plates 3 on the same side. The moving component 4 is engaged with the sealing plate 2 and can drive the sealing plate 2 to move, thus playing the role of a switch.
[0026] Two symmetrical limiting grooves 101 are provided at the upper ends of the left and right side walls of the galvanizing pool 1. Correspondingly, a limiting strip 201 is provided on the lower side of the sealing plate 2. The limiting strip 201 is located in the limiting groove 101. The two are slidably connected. When the sealing plate 2 moves, the limiting strip 201 also moves in the limiting groove 101. When the sealing plate 2 does not move, the two play a sealing role.
[0027] Moreover, limit blocks 202 are provided on both the front and rear sides of the sealing plate 2. The limit blocks 202 are located at one end where the two sealing plates 2 are close to each other. When the sealing plates 2 are away from each other, the limit blocks 202 come into contact with the limit plates 3, which restricts the sealing plates 2, thereby preventing the sealing plates 2 from moving to both sides and being separated from the galvanizing tank 1, thereby achieving a protective effect.
[0028] The moving assembly 4 is located outside the galvanizing pool 1. It will not be affected by the high temperature in the galvanizing pool 1, nor will it be corrosive by the exhaust gas. The moving assembly 4 includes a rack 401, a motor 402 and a gear 403. The rack 401 is horizontally fixed to the upper surface of the sealing plate 2 and can move between the front and rear limit plates 3. The rack 401 engages with the gear 403. The gear 403 is installed on the output shaft of the motor 402, and the motor 402 is installed on one of the limit plates 3. Therefore, after the motor 402 is started, it can rotate the gear 403. The rotation of the gear 403 drives the rack 401 to move horizontally to the left or right, and the rack 401 will move with the sealing plates 2. When the two sealing plates 2 move, they can move closer to or away from each other, which can realize the switching between the two sealing plates 2;
[0029] A side hole 203 is further provided at one end of the two sealing plates 2 that is close to each other. When the two side holes 203 are closed, a suspension rod 6 is provided in the side hole 203. The radius of the side hole 203 is the same as the outer diameter of the suspension rod 6 to ensure sealing. The top of the suspension rod 6 is connected to an external lifting device, and a placement frame 7 is provided at the bottom thereof for holding the material to be galvanized.
[0030] During operation, the boom 6 carries the placement frame 7 containing the material and is positioned above the galvanizing pool 1. Then the moving assembly 4 drives the two sealing plates 2 away from each other, opening the galvanizing pool 1. The boom 6 moves down to place the placement frame 7 in the galvanizing pool 1. At this time, the moving assembly 4 drives the two sealing plates 2 back to their original closed state. At the same time, the side holes 203 cooperate with the boom 6. After the galvanizing is completed, the sealing plates 2 are opened again, the material is taken out, and then the sealing plates 2 are closed and wait for the next operation.
[0031] An exhaust pipe 5 is installed on the rear side of the galvanizing pool 1. The exhaust pipe 5 can be connected to an external waste gas treatment device, which can transmit the waste gas generated during the galvanizing process in the galvanizing pool 1 to the treatment device to complete the purification of the waste gas and avoid pollution.
[0032] In the present invention, a motor 402, a gear 403, a rack 401, a limit plate 3, a sealing plate 2 and other structures are provided, which cooperate with each other to close and seal the galvanizing pool 1 during galvanizing to prevent the escape of exhaust gas and achieve a protective effect. At the same time, all structural parts are placed outside the galvanizing pool 1, and are not affected by the high temperature of the galvanizing pool 1 and the corrosion of exhaust gas, and can be used for a long time.
[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
