Abstract

The invention provides a powder feeding device, belonging to a vibrating feeding device and solving the problems that the existing vibrating feeding device has potential safety hazards, can not vibrate to sieve and lacks heat-preservation treatment. The powder feeding device comprises a heat-preservation material cylinder, a weighing device, a bracket, a hopper and a controller, wherein the weighing device is arranged on the bracket; the upper part of the heat-preservation material cylinder is connected with the weighing device; the lower end of the heat-preservation material cylinder is flexibly connected with the hopper; the upper end face of the hopper is provided with a sieving net; the side face of the hopper is provided with a pneumatic vibration exciter; the bottom part of the hopper is connected with a pneumatic rubber pipe valve and a material discharging pipe; the weighing device is connected with the controller through a cable; the controller is connected with an electric ratio adjusting valve through the cable; an air inlet of the electric ratio adjusting valve is connected with an air source; and an air outlet of the electric ratio adjusting valve is respectively connected with the pneumatic vibration exciter and the pneumatic rubber pipe valve. The powder feeding device provided by the invention has the advantages of simple structure, safety and reliability, capability of vibrating to sieve, capability of remotely controlling a powder falling speed, convenience in operation and easiness in transportation; and in a feeding process, the heat-preservation treatment can be carried out, thus the powder feeding device is suitable for adding combustible and explosive powder.

Description

technical field [0001] The invention belongs to a vibration feeding device, which is used for adding inflammable and explosive powder. Background technique [0002] In the powder feeding operation, the transportation of materials often needs to be evenly fed to the conveyor through a hopper. For some powders, due to uneven or uncontrollable feeding, it is easy to cause problems such as material absorption and arching to cause blockage. The utility model patent of authorized notification number CN201873300 U discloses an explosion-proof solid phase continuous automatic feeding device, which is composed of a metering silo, a feeding silo, a material pump, a motor, a weighing device, a controller, etc. It has the advantages of remote control of the feeding and feeding process and low investment costs, but there are still shortcomings: a. Due to the use of motor-driven feeding devices and arch breaking devices, there are safety hazards when adding flammable and explosive powder...
