Description

Technical Field

[0001] This utility model relates to the technical field of fume hoods, and in particular to fume hoods for galvanized pots. Background Technology

[0002] A galvanizing pot is a device used to coat metal surfaces with an anti-corrosion layer. It coats the metal surface with molten zinc to form a strong protective layer to prevent oxidation and corrosion. This equipment is commonly used in the manufacture of building materials such as metal pipes, roofs, and walls, and is of great significance to the metal manufacturing industry. At the same time, galvanizing pots are also a type of coating equipment. This type of equipment uses specific processes and technologies to form a thin film on the metal surface, including tin-plating machines, chrome-plating machines, electroplating equipment, and thermal spraying equipment. When materials are galvanized in a galvanizing pot, a large amount of fumes are generated, which pollutes the operating environment.

[0003] The existing Chinese utility model patent with application number CN202023235479.7 relates to a smoke absorption device for a zinc pan used for galvanizing workpieces, including a pan, a smoke hood, a smoke exhaust fan, a factory wall, a smoke exhaust pipe, and a box, which can improve the absorption effect of smoke.

[0004] However, in actual use, the above-mentioned device is designed for use with existing large pot bodies, and completely covering the pot body will affect the normal operation of the operator. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a galvanized pot exhaust hood that connects a mobile device and a driving device. The driving device works in conjunction with the mobile device to cover or expose the pot body, facilitating operation by an external crane and improving the practicality of the device.

[0006] This utility model relates to a galvanized pot exhaust hood, which includes a driving device and a moving device. The moving device is mounted on the driving device, and a limiting baffle is mounted on the driving device.

[0007] Preferably, the drive device includes a bracket, a gantry, a reducer, a motor, a shaft mounting base, a shaft, a chain, a guide wheel, and a sprocket. The gantry itself is arched, and the main body of the gantry is channel steel. A set of brackets is connected to the lower left and right sides of the gantry. A reducer is installed in the front of the bracket, and a motor is installed on the reducer. A partition is vertically installed in the middle of the bracket. A set of shafts is installed on the upper and lower parts of the outer side of each set of partitions through two sets of shaft mounting bases. The lower shaft is connected to the output end of the reducer in its bracket. The middle part of the lower shaft in one set of brackets is fitted with... Equipped with sprockets, a set of guide wheels is mounted on the left and right sides of the upper rotating shaft inside the bracket; another set of guide wheels is mounted on the left and right sides of the lower rotating shaft inside the bracket, and a set of sprockets is mounted in the middle of the upper rotating shaft inside the bracket. The three sets of chains are mounted parallel to each other on the guide wheels and sprockets in the two sets of brackets, and the main body of the chains passes over the upper part of the gantry. When the motor is turned on, the power is transmitted to the rotating shaft connected to it through the reducer, which drives the rotating shaft to rotate. Through the cooperation of the guide wheels and sprockets, the chain is driven to rotate, thereby providing power for the moving device and improving the practicality of the device.

[0008] Preferably, the moving device includes a C-shaped frame, a connecting plate, traveling wheels, a traveling connecting plate, side traveling wheels, a cross plate, and a first chain connecting plate. Two sets of connecting plates are bolted to the sides of the two sets of C-shaped frames. A set of rotating shafts is installed at the top and bottom of each C-shaped frame, and two sets of traveling wheels are mounted on the rotating shafts. Two sets of traveling connecting plates are bolted to the inner side of one set of connecting plates. The side traveling wheels are mounted on the inner side of the two sets of traveling connecting plates via brackets and connected to the inner side of the two sets of traveling connecting plates. Two sets of first chain connecting plates are connected to the two sets of chains located on both sides of the gantry. The two sets of first chain connecting plates are located on both sides of the gantry, and one set of first chain connecting plates...

A set of brackets consisting of two sets of C-shaped frames and connecting plates is fitted onto the lower left and right sides of the gantry. A set of second chain connecting plates is connected to the left and right sides of the middle chain among the three chains. The second chain connecting plates on both sides are located on the side of the chain closest to the gantry and the side of the chain furthest from the gantry, respectively. The sides of the second chain connecting plates are connected to the bottom connecting plate via brackets. The second chain connecting plates on both sides are at the same horizontal height. A set of driving devices is provided on each side of the pot body. Two sets of dust covers are located on the left and right sides of the two sets of gantry frames, respectively. The upper edges of the dust covers are respectively... The device is connected to the moving device on the same side of the two sets of masts. The lower edge of the dust cover is connected to the connecting plate on the bottom of the same side of the two sets of masts. The moving device is driven by the drive device to move, thereby causing the dust cover to rise from the bottom to cover the pot body, reducing the pollution of the operating environment caused by the flue gas during the production process. During the processing, the drive device is controlled to lift the frame composed of C-shaped frame and connecting plate at the bottom of the mast according to the needs, thereby causing the bottom of the dust cover to rise, so that the operator can enter the side of the pot body from the bottom to operate. After the processing is completed, the dust covers on both sides are lowered to facilitate the removal of the workpiece by the crane equipment, which improves the practicality of the device.

[0010] Preferably, it also includes a limiting baffle. A limiting baffle is provided on the top of the gantry, and a rectangular groove is provided on the upper part of the limiting baffle for the chain to pass through. The limiting baffle on the top of the gantry limits the movement position of the moving device to prevent the moving devices on both sides of the gantry from colliding. The top edge of the dust cover is connected by magnetic strips or other adhesive methods to increase the sealing of the top of the dust cover. This is not restricted here, and it is convenient to collect the fumes generated during galvanizing and treat them in conjunction with environmental protection equipment, thereby improving the practicality of the device.

[0011] Preferably, it also includes rollers, with rollers mounted on the chain's connecting shaft; the rollers mounted on the chain's connecting shaft facilitate the movement of the chain on the gantry, reduce frictional wear between the chain and the gantry, and improve the service life of the equipment.

[0012] Preferably, the device further includes placing multiple sets of moving devices between the moving device and the frame composed of the bottom C-shaped frame and the connecting plate. The moving device placed in the middle is not connected to the chain, and the two sides of the dust cover are respectively connected to the frames of multiple sets of moving devices located in the middle. By connecting the moving device added in the middle to the edge of the dust cover, the gap between the dust cover and the frame is reduced, and the practicality of the device is improved.

A sliding door is installed on the left side of the arched frame, and a glass observation window is provided on the sliding door. The arched frame and sliding door obstruct and seal the sides of the gantry, reducing smoke escaping from inside the arched frame. The glass observation window allows operators to easily observe the situation in the galvanizing pot, improving the practicality of the device.
