Description

Technical Field

[0001] The present application relates to the technical field of dust suppression devices, and in particular to a dust suppression device used in a cathode carbon block production workshop. Background Art

[0002] Cathode carbon block refers to a carbon block made of high-quality anthracite, coke, graphite, etc. It is used as the cathode of the aluminum electrolytic cell. It is built at the bottom of the electrolytic cell and is also called the bottom carbon block. Cathode carbon block is an important component of the aluminum electrolytic cell, which is beneficial to energy saving in aluminum electrolysis production and improving the life of the cell. During its processing, a large amount of dust will appear in the production workshop, so a dust suppression device is needed to deal with the dust.

[0003] In the patent document with the published announcement number CN220176403U, a dust suppression device for workshops is provided, including a device box and a dust suppression water cannon, the device box is rotatably connected to a rotating rod inside, the top of the rotating rod extends to the top of the device box and is fixedly connected to a displacement plate, a driving motor is fixedly installed on the top of the device box and on one side of the displacement plate, a linkage mechanism is provided on one side of the rotating rod, the linkage mechanism is used to drive the displacement plate to swing, two vertical plates are fixedly connected to the top ends of the displacement plate, and the dust suppression water cannon is rotatably connected between the two vertical plates. The utility model has solved the problem that when using a dust suppression water cannon for dust suppression, the dust suppression water cannon can only adjust the angle up and down, so that water can only be sprayed in one direction, and the production workshop is generally large, so this device cannot comprehensively and effectively perform dust suppression in the workshop, and when dust suppression is required in other places, it is necessary to manually move the position, thereby reducing the practicality of the device and increasing its limitations.

[0004] The above-mentioned device is easy to move by installing rollers, and is easy to move to different positions for dust reduction operations. However, the position of the rollers in the above-mentioned device cannot be adjusted, which results in the rollers being in contact with the ground for a long time when they do not need to be moved, and needing to bear the pressure of the weight of the device itself, which makes the rollers easy to be damaged and affects movement. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present application provides a dust reduction device for a cathode carbon block production workshop, which overcomes the deficiencies of the prior art and aims to solve the problems in the prior art.

[0007] As a preferred technical solution of the present application, a bearing is fixedly mounted on the top of the fixed plate, and the bottom end of the screw rod is fixedly connected to the inner ring of the bearing.

[0008] By adopting the above technical solution, it is possible to limit the screw rod during rotation, thereby ensuring that the screw rod will not arbitrarily deviate or swing in position during rotation.

[0009] As a preferred technical solution of the present application, a threaded hole is opened through the center position of the lifting plate, the screw rod is threadedly connected to the inner wall position of the threaded hole, the four sides of the lifting plate are respectively fitted with the inner wall of the moving box, the number of the rollers is four, and the four rollers are symmetrically arranged at the bottom position of the lifting plate.

[0010] By adopting the above technical solution, when the screw rod rotates, the lifting plate and the roller can be driven to move up and down through the threaded hole, so as to adjust the height of the roller and ensure that the roller does not need to be in contact with the ground for a long time when the device is not in use or moving.

[0011] As a preferred technical solution of the present application, the bottom of the filter cotton plate is fitted with the top of the positioning column, and the positioning column and the filter cotton plate are fixedly connected by fixing bolts.

[0012] By adopting the above technical solution, the filter cotton plate can be stably positioned in the inner cavity of the storage box to ensure that it will not be arbitrarily dislocated when impacted by gas.

[0013] As a preferred technical solution of the present application, two handles are fixedly mounted on the top of the sealing cover, and air outlets are evenly arranged on the top of the sealing cover.

[0014] By adopting the above technical solution, the convenience of the user rotating the sealing cover to drive the threaded ring to rotate is increased, and it is easy to open the sealing cover and take out the filter cotton plate for cleaning.

[0015] As a preferred technical solution of the present application, the outer diameter of the filter cotton plate is matched with the inner wall diameter of the storage box.

[0016] By adopting the above technical solution, the mixture of cathode carbon ash and air absorbed by the suction nozzle can be discharged into the inner cavity of the storage box and filtered by the filter cotton board before being discharged to the outside through the air outlet, thereby improving the thoroughness of the filtration.

[0017] Beneficial effects of this application:

[0018] 1. The screw rod is driven to rotate by starting the motor, and then the screw rod rotates through the threaded hole to drive the lifting plate and the roller to move up and down, so as to adjust the height of the roller. This ensures that the roller does not need to be in contact with the ground for a long time when the device is not in use or moving, and can be stored in the inner cavity of the moving box. Therefore, the roller has no place to bear the pressure of the weight of the device itself for a long time, thereby improving the service life of the roller.

[0019] 2. Start the vacuum pump and cooperate with the suction tube and nozzle to absorb the dust in the cathode carbon block production workshop into the inner cavity of the storage box, and then filter the cathode carbon ash through the filter cotton plate and discharge it to the outside at the air outlet. When dust removal is not needed, the sealing cover can be turned by the handle to drive the threaded ring to rotate, thereby separating the threaded ring from the storage box, and then open the sealing cover to remove the fixing bolts to take out the filter cotton plate for cleaning and replacement, which improves the convenience of cleaning and replacing the filter cotton plate.
