Arch breaking and unblocking device for material sending tank and arch breaking method

Abstract

The invention provides an arch breaking and unblocking device for a material sending tank and an arch breaking method. The arch breaking and unblocking device comprises a rotary fan cover, a fixed fan cover, an air chamber, a rotary shaft, a stepping motor, an air supply system and a control system. The fixed fan cover sleeves the rotary fan cover, the inner wall face of the fixed fan cover is matched with the outer wall face of the rotary fan cover in shape and size, the center line of the rotary fan cover and the center line of the fixed fan cover are located on the same straight line, and rotary blowing air holes are formed in the side wall of the rotary fan cover. Fixed blowing air holes which are the same as the rotary blowing air holes in number and size are formed in the side wall of the fixed fan cover, the rotary blowing air holes and the fixed blowing air holes coincide in the rotating motion trail of the rotary fan cover, the stepping motor works to drive the rotary fan cover to rotate, intermittent coincidence of the blowing air holes is achieved, when the blowing air holes coincide, strong pulse wind can be jetted to arching materials in a sending tank, and the problems of arching, bridging, wall sticking and retention in the material sending tank are effectively solved.

Description

technical field [0001] The invention relates to the technical field of loosening and arch breaking of easily bonded materials, in particular to an arch breaking and blocking removal device and an arch breaking method for material delivery tanks. Background technique [0002] In the process of sending cohesive materials, phenomena such as material arching and bridging, sticking to the wall and retention often occur, which seriously affect the operation quality and production efficiency of the sending process, and there are potential safety hazards. In order to solve the above technical problems, an arch breaking and blocking removal device can be installed on the inner wall of the material delivery tank. [0003] Chinese patent CN213567723U provides a silo powder arch breaking device. In this invention, a high-pressure compressed air nozzle is arranged inside the silo, and the nozzles are connected to the air intake pipe and the air compression device in turn. The valve open...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the arch breaking effect in the prior art is poor, and the pulse wind cannot be controlled in time according to the arch breaking effect, and to provide an arch breaking and blocking removal device and arch breaking method for material delivery tanks, which can effectively break the arch and at the same time Combined with the effect of breaking the arch and clearing the blockage inside the sending tank, the pulse width and pulse interval of the pulse jet blowing are adjusted, which is stable, reliable, simple and controllable
