Automatic powder feeding device

Abstract

The invention discloses an automatic powder feeding device which comprises a level indicator device, a screw conveyor, an ash conveying pipeline, a high-pressure fan, an observation window access hole, a crawling ladder, a powder feeding protection device, a feed cylinder, and a powder feeding guardrail. The crawling ladder is arranged on the side of a support frame; one end of the crawling ladderis connected with the support frame; the other end of the crawling ladder is connected with the crawling ladder and the powder feeding protection device; the level indicator device, the screw conveyor, the ash conveying pipeline, the high-pressure fan, the observation window access hole, a speed reducer, an ash hopper and a tank are arranged in the support frame; the side of the top end of the support frame is connected with the top end of the ash hopper; the observation window access hole and the level indicator device are arranged on an outer side panel of the ash hopper; the speed reduceris arranged under the ash hopper; and the screw conveyor is connected to the side of the speed reducer. According to the automatic powder feeding device provided by the invention, when a deduster works, a lime powder feeder is arranged according to the system parameters, and the powder feeding rate per hour is set according to the demand of an owner, so that the automatic powder feeding device isstable to work, high in efficiency and convenient to use.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an automatic powder feeding device. Background technique [0002] The powder feeder is a new type of dilute-phase continuous micro-positive pressure pneumatic conveying equipment, which is used for the transportation of fly ash collected by dust collectors in thermal power plants. Or the transportation of the cement warehouse into the packaging warehouse, used for the homogenization system of the cement warehouse, used for the centralized transportation of coal coke powder in the coal chemical industry, and used for the transportation of other powdery materials. The existing slope surface storage at the air inlet end of the powder feeder Too much, the passing capacity will decrease, the local resistance will increase, it will not be able to decelerate and switch, and the amount of ash conveyed cannot be controlled. There will be a large number of small particles during the po...

Problems solved by technology

[0002] The powder feeder is a new type of dilute-phase continuous micro-positive pressure pneumatic conveying equipment, which is used for the transportation of fly ash collected by dust collectors in thermal power plants, mainly used for the transportation of limestone powder in boiler desulfurization systems, and for cement transportation warehouses. Or the transportation of the cement warehouse into the packaging warehouse, used for the homogenization system of the cement warehouse, used for the centralized transportation of coal coke powder in the coal chemical industry, and used for the transportation of other powdery materials. The existing powder feeder inlet slope surface storage Too much, the passing capacity decreases, the local resistance increases, the deceleration conversion cannot be performed, and the ash conveying volume cannot be controlled. There will be a large number of small particles during the powder feeding process, and the phenomenon of more or less powder feeding is inconvenient to use.
