Description

Technical Field

[0001] The utility model relates to the technical field of fan shutoffs, in particular to a fan shutoff capable of preventing blockage. Background Art

[0002] The fan shut-off valve, also known as a rotary valve, discharge valve, etc., is mainly used in pneumatic conveying systems to play the role of quantitative feeding and air locking. It is usually composed of a rotor and a shell. The rotor rotates in the shell, and the gap between the blades on the rotor and the shell is used to control the amount of material passing through. When working, when the material enters the fan shut-off valve from above, the rotor rotates to push the material out quantitatively, and at the same time it can prevent external air from backflowing into the conveying system to ensure the air tightness of the system.

[0003] For example, a fan that prevents blockage in the prior art is connected to a reducer by bolts at one end of a working box, and a first motor is connected to one side of the reducer by bolts. The device body also includes an anti-blocking component, a disassembly component, a rotating component and a circular connecting plate. An anti-blocking component is arranged on the top of the feed port, and the anti-blocking component includes a second motor, a first transmission belt, a transmission wheel, a first driven wheel, a top plate, a first worm, a movable block, a scraper rod, a second transmission belt, a second driven wheel, a second worm and a slide groove. The second motor is connected to one end of the top plate by bolts. The utility model cooperates with the anti-blocking component and the disassembly component to achieve efficient material discharge while avoiding material blockage in the discharge process, and facilitates internal cleaning, thereby improving the practicability of the device and making the device more applicable.

[0004] When the device is in use, the two worms are driven to rotate by a motor, and then the movable block is threadedly connected to the outer side of the worm, thereby driving the scraper to clear the blocked material. However, since the worm and the movable block are both arranged inside the anti-blocking component, it is very easy to cause the conveyed material to accumulate on the worm during use, thereby increasing the friction of the worm during operation, causing increased wear and shortening the service life of the worm.

[0005] Therefore, it is necessary to provide a fan that can prevent blockage to solve the above technical problems. Utility Model Content
