Blocking prevention star-shaped feeding device and feeding method

Abstract

The invention relates to a blocking prevention star-shaped feeding device. The blocking prevention star-shaped feeding device comprises a rack, a rotor and blocking prevention devices. The rack comprises a feed port, a discharge port and centrosymmetric feeding grooves. The two sides of the rotor are provided with symmetric movable sealing plates, the upper ends of the movable sealing plates are connected to the feeding grooves through supporting rotating shafts, an open U-shaped space is formed by the lower ends of the movable sealing plates, and openings in the lower ends of the movable sealing plates are right opposite to the discharge port. Each blocking prevention device is located at a position, accounting for 1 / 3-1 / 2 of the distance between the corresponding supporting rotating shaft and the discharge port in the direction from the corresponding supporting rotating shaft to the discharge port. Each blocking prevention device comprises a shaft sleeve, wherein the shaft sleeve isfixed to the rack, the shaft sleeve is internally provided with a movable jacking shaft connected through a spring, the movable jacking shaft extends or retracts in the shaft sleeve, the end portion of the movable jacking shaft makes contact with the outer side wall of the corresponding movable sealing plate, and the extensible and retractable axis is perpendicular to the contact face of the movable jacking shaft and the outer side wall of the corresponding movable sealing plate. By means of the blocking prevention star-shaped feeding device, when materials are blocked in the feeding process,the movable sealing plates are extruded to outwards rotate and deform around the corresponding supporting rotating shafts, after the materials pass through the device, the blocking prevention devicesreset, and the material blocking and material crushing problems are solved.

Description

Technical field [0001] The present invention generally relates to the field of metallurgical technology, in particular to an anti-blocking star-shaped feeding device and a feeding method. Background technique [0002] In the fields of chemical and metallurgical production, continuous feeding and discharging of the reaction device are often encountered. Commonly used equipment is star feeder or screw feeder. Different working environments often have certain requirements for feeding equipment. The metallurgical industry has certain requirements for the particle size of raw materials due to the needs of production. When the traditional star feeder conveys some large particles, the large particles are easily crushed between the top of the blade and the inner wall of the shell. It may cause jamming, which may damage the blades, even make the rotor unable to rotate, and the star feeder cannot operate normally. Therefore, when the traditional star feeder is used for feeding, there are ...

AI Technical Summary

Problems solved by technology

Due to the needs of production, the metallurgical industry has certain requirements on the particle size of raw materials. When the traditional star feeder conveys some large-grained materials, the large-grained materials are easily crushed between the top of the blade and the inner wall of the shell, and Cause jamming, may damage the blade, and even make the rotor unable to rotate, and the star feeder cannot operate normally

Therefore, when the traditional star feeder is used for feeding, there are problems such as material jams and broken materials to a certain extent, and these problems will affect the normal operation of production
