Flexible powder valve device at dynamic and static joint and opening and closing method

Abstract

The invention discloses a flexible powder valve device at the dynamic and static joint and an opening and closing method. The flexible powder valve device comprises curtain cloth, an upper buckle and a lower buckle, wherein the top of the surface of the curtain cloth is used in cooperation with the surface of the upper buckle, and the bottom of the surface of the curtain cloth is used in cooperation with the surface of the lower buckle. Through cooperative use of the curtain cloth, the upper buckle, the lower buckle, a bag type air spring, a breather pipe, a first fixing disc, a first fixing rod, a limiting mechanism, a limiting rod, a sealing plate, a limiting pipe, a second fixing disc, a second fixing rod, a limiting block, a reset spring, a sealing ring, a feeding port, a discharging port and a screw, the device solves the problems that when the whole existing vibrating granulator shakes when being used, the vibrating granulator needs to be stopped for feeding during feeding, then the working efficiency is reduced, and the use is not facilitated. The flexible powder valve device at the dynamic and static joint and the opening and closing method have the advantage of continuous feeding, and the requirement for continuous feeding of the vibrating granulator is met.

Description

technical field [0001] The invention belongs to the technical field of flexible powder valves, in particular to a flexible powder valve device and an opening and closing method for dynamic and static joints. Background technique [0002] The powder is an aggregate composed of many small particles, and its common characteristics are: it has many discontinuous surfaces, a large specific surface area, and is composed of many small particles. The vibration granulator needs to be fed, but vibration makes The granulator shakes as a whole when it is in use, and it is necessary to stop the vibrating granulator for feeding when feeding, which reduces the work efficiency and is not conducive to use. Therefore, a method that can be used to feed the vibrating granulator when the equipment is working is required to meet the requirements for vibration. The demand for continuous feeding of the granulator. Contents of the invention [0003] Aiming at the problems existing in the prior ar...

Problems solved by technology

[0003] Aiming at the problems existing in the prior art, the present invention provides a flexible powder valve device and an opening and closing method at the dynamic and static joints, which has the advantage of continuous feeding, and solves the problem that the existing vibrating granulator shakes when it is in use and needs to be vibrated when feeding. The granulator stops feeding, which reduces the work efficiency and is not conducive to the use of the problem
