Description

Technical Field

[0001] The utility model belongs to the technical field of graphite manufacturing, and in particular relates to a positive pressure anti-corrosion and dust-proof system for an overhead crane. Background Art

[0002] During the graphitization process in the new energy anode industry, large amounts of dust and highly corrosive gases are discharged into the factory floor, significantly reducing the service life of electrical components in critical equipment such as overhead cranes. The power room on the overhead crane is air-conditioned, creating a slight negative pressure inside. Even with its airtight design, it's difficult to prevent outside air from entering. Because the overhead crane is frequently mobile, it can't be connected to a fixed gas pipeline. Prior Art Publication No. CN201563314U discloses a protective device for an electrical control cabinet suitable for a multifunctional overhead crane for baking. The device comprises an electrical control cabinet (room) body, which contains a sealed cavity containing electrical control components. The electrical control cabinet (room) body has an air inlet and an air outlet. An air filter is installed at the inlet end of the inlet. An oil-water separator, an air dryer, and a pressure regulator are connected in series to the outlet end of the outlet. Compressed air is injected into the sealed cavity of the electrical control cabinet (room) body through the air inlet, maintaining a constant positive pressure within the sealed cavity. A disadvantage of this device is that it merely filters the air near the overhead crane and draws it into the electrical power room, failing to completely remove the highly corrosive components in the air. In actual production, the main cause of electrical equipment failures is corrosive gases. Therefore, ensuring that clean compressed air is introduced into the electrical room is the correct measure to reduce the electrical failure rate of overhead cranes. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above shortcomings and provide a crane positive pressure anti-corrosion and dustproof system that delivers clean compressed air into the factory through a pipeline, maintains the positive pressure burden in the power room, and prevents corrosive gases from causing electrical equipment failures.

[0004] The utility model provides a positive pressure anti-corrosion and dust-proof system for an overhead crane, comprising an overhead crane electrical power room, a pulse valve, an air storage tank, a sensor, a controller, and a sealed door, and is characterized in that the air storage tank passes through the overhead crane electrical power room through a pipeline to connect to the pulse valve, the overhead crane electrical power room is respectively equipped with a pulse valve, a pressure difference sensor, and a controller, and a sealed door is installed on one side of the overhead crane electrical power room through a sealing strip.

[0005] The controller is connected to the pulse valve, the sensor, and the power supply in the control cabinet through wires, and the power supply in the cabinet is connected to the pulse valve through wires.

[0006] The sensor is a differential pressure sensor.

[0007] A compressed air quick connector is installed on the pipeline at one end of the air storage tank.

[0008] Compared with the prior art, the present invention has obvious beneficial effects; from the above technical solution, it can be seen that: the pulse valve is connected through the air storage tank through the pipeline through the overhead crane electrical power room, and the overhead crane electrical power room is respectively installed with a pulse valve, a pressure difference sensor, and a controller, and a sealing door is installed on one side of the overhead crane electrical power room through a sealing strip. First, the compressed air introduced into the workshop is introduced into the air storage tank through a quick connector for standby use, and then the controller is turned on, and the pressure difference inside and outside the electrical power room is detected by the pressure difference sensor, and the signal is transmitted to the controller. The controller controls the pulse valve to perform pulse control, so that the indoor pressure of the electrical power room is maintained at 48-52pa, so that external gas cannot enter the interior of the electrical power room, and the effect of corrosion and dust prevention is achieved. By sending clean compressed air into the electrical power room through a pipeline, the positive pressure in the electrical power room is maintained. It is achieved that clean compressed air is sent into the factory through a pipeline, the burden of maintaining the positive pressure in the power room is maintained, and corrosive gases are prevented from causing electrical equipment failures.

[0016] When in use; first, the compressed air introduced into the workshop is introduced into the air storage tank 3 through the quick connector 6 for standby use. The staff opens the sealed door 7 to enter the electrical power room 1, closes the sealed door 7, and then turns on the controller 5 in the electrical power room 1.
