Anti-blocking star type unloading valve for coarse powder separator powder return pipe

Abstract

The invention discloses an anti-blocking star type unloading valve for a coarse powder separator powder return pipe. The anti-blocking star type unloading valve comprises a base, the outer wall of thebase is provided with a first rotating wheel, the inner wall of the first rotating wheel is connected with the outer wall of the base, the outer wall of the first rotating wheel is provided with a belt, the inner wall of the belt is connected with the outer wall of the first rotating wheel, and a second rotating wheel is arranged on the right side of the inner wall of the belt. According to the anti-blocking star type unloading valve for the coarse powder separator powder return pipe, through cooperation of the base, a rack and a box body, under the effect of a side plate, fixed connection ofthe box body and the motor is achieved through the rack, the bearing capacity of the box body and an overturning plate is increased, the problem about motor base interior connection instability or rack breakage caused by too large downward pressure borne by long-time work of a motor base and the rack is solved, the side plate is adopted on the outer wall of the box body for reinforced connection,and the defect that a traditional anti-blocking star type unloading valve for the coarse powder separator powder return pipe is low in bearing force and poor in stability is avoided.

Description

Technical field [0001] The invention relates to the technical field of industrial production, in particular to an anti-blocking star type discharge valve of a powder return pipe of a coarse powder separator. Background technique [0002] The air locker is a device that only allows pulverized coal to pass through but not air. Due to the large negative pressure in the cyclone separator, if there is no air lock, not only the pulverized coal cannot enter the powder storage silo, but the air leaking from the atmosphere will seriously damage the normal operation of the cyclone separator, making the separation efficiency of the separator greatly Reduced, the current commonly used air locks are complex in structure and high in production costs. They need to be opened manually to collect pulverized coal, which is inconvenient to use. They are widely used in building materials, metallurgy, chemical, electric power and other sectors as ash hoppers for various dust removal equipment. The de...

Problems solved by technology

Due to the large negative pressure in the cyclone separator, if there is no air lock, not only the coal powder cannot enter the powder storage bin, but also the air leaking in from the atmosphere will seriously damage the normal operation of the cyclone separator, so that the separation efficiency of the separator will be greatly improved. Reduced, the commonly used gas locker has a complex structure and high production cost, and it needs to be manually opened to collect coal powder. The device is a special equipment for uniform feeding and sealing of various powdery and small particle materials. It can be used as a feeding device for various scraper machines, mills, dryers, silos and other equipment to lock air The device relies on the gravity of the material and the coercive action of the working mechanism of the feeder to discharge the material in the scraper machine and feed it into the next device continuously and evenly. In the prior art, for example, the invention with application number 201320060490.5 The patent includes the shell, the upper left of the shell is provided with a pipe, the bottom of the pipe is provided with a flap, the bottom of the flap is a lever, the lever is connected to the pipe through a fulcrum, and the right end of the lever is provided with a weight. Although the structure of the invention is simple, but There are many deficiencies and defects. In the existing equipment, the design of the flap is flawed. When the material falls too fast, the flap will be stuck by the material at the moment of flipping, and the material will continue to fall, causing the pipeline to be blocked. The design of the hammer also has shortcomings. The opening device composed of the fulcrum and the weight has poor sensitivity. If it fails, it needs to be cleaned manually, which increases the production cost. In view of these situations, in order to avoid the above technical problems, it is necessary to provide a coarse powder separator. The anti-blocking star discharge valve of pipe to overcome the said defect in the prior art
