Pneumatic hot wind coal flow isolated door

Abstract

The invention discloses a pneumatic hot wind coal flow isolated door, solving the problem of the existing device that the material can be easily stopped in the coal container, wherein a flashboard is formed, a plate hole being the same in size with the inner diameter of the coal container is formed in a half of the flashboard, the length of the flashboard fixing bracket is the inner diameter of three plate holes at least; an air cylinder is fixed at one end of theflashboard fixing bracket; the flashboard is connected to the piston rod of the air cylinder, the gas tube path I, the gas tube path II of the air cylinder are respectively connected to a pneumatic reversing valve, which is connected to a gas storing pot; a baffle is formed at the end of the flashboard far from the coal container and a limit plate is formed above the flashboard of the flashboard fixing bracket. Full-through hole design is used in the pneumatic hot wind coal flow isolated door, the round through diameter of the plate hole is the same with the coal container, the opening and closing operation is flexible, the power is enough, the starting and stopping speed is fast, the coal will not be stopped or blocked for effectively solving the stopping phenomenon for prior coal container.

Description

technical field [0001] The invention relates to an isolating door, more specifically to a pneumatic hot air coal flow isolating door. Background technique [0002] In the process of conveying solid materials in the form of powder, granular, block or their mixtures, the phenomenon of material blocking occurs from time to time, especially in the process of conveying raw coal in thermal power plants, it often encounters coal sticking, awning coal, and coal blocking in the coal hopper , so it is necessary to cut off the logistics to facilitate maintenance. [0003] Due to the design defects of the track, track groove, and side groove in the existing cutting device, the middle part is formed by the expansion space, forming a dead angle, which can easily cause coal powder to stick to the wall, bridge, and shed blockage, affecting the safe and economical operation of subsequent equipment. Especially in thermal power plants, the clogging of raw coal hopper materials often occurs, s...
