Description

Technical Field

[0001] The invention relates to the technical field of fused magnesia production, in particular to a pulverizing device for fused magnesia production with a dust removal effect. Background Art

[0002] In the process of producing and processing fused magnesia, a crushing device is needed to break up and crush the fused magnesia, so as to facilitate the subsequent processing of the fused magnesia.

[0003] Usually, it is necessary to pour the fused magnesia raw materials into the inner wall of the crushing device, and then start the crushing machine to rotate, so as to achieve the purpose of breaking up and crushing the fused magnesia raw materials. After the fused magnesia raw materials are completely broken up and crushed, the fused magnesia in the inner wall of the cylinder is discharged by opening the discharge pipe.

[0004] Considering that during the process of crushing the fused magnesia, the outer wall of the stirring rod squeezes and collides with the fused magnesia, a part of the fused magnesia dust is discharged outward along the discharge port set at the top of the crushing device, affecting the hygiene of the working environment. At the same time, after crushing, a part of the fused magnesia adheres to or remains on the inner wall of the crushing device. Considering that the quality and proportion of each batch of fused magnesia production are different, the residual fused magnesia affects the purity and quality of the next proportion production.

[0016] Working principle: Pour the fused magnesia raw material into the inner wall of the cylinder through the feeding pipe, and start the motor to drive the shaft to rotate, so that the shaft pushes the fused magnesia raw material to move through the stirring rod arranged on the outer wall, and cooperates with the crushing rod arranged on the inner wall of the cylinder to squeeze, so that the stirring rod passes through the gap on the crushing rod, thereby crushing the pushed fused magnesia.

[0017] During the rotation of the shaft, the bevel gear A set on the top is driven to rotate, so that the bevel gear A drives the bevel gear B to rotate, and the bevel gear B drives the rod body to rotate, so that the push plate set on the outer wall of the rod body moves, and the force of the scroll spring is used to squeeze the outer wall of the triangular plate, so that the triangular plate drives the ring body to rotate, and the ring body rotates along the inner wall of the cylinder body, and drives the arc baffle to move right, so that the arc baffle closes the feed pipe set on the cylinder body, so that the device automatically closes the feed pipe before crushing the fused magnesia raw material, thereby preventing the dust generated in the crushing process from being discharged to the outside, thereby achieving the purpose of dust removal.

[0018] At the same time, after the crushing is completed, when the inner wall of the cylinder needs to be scraped and cleaned, the staff presses the limit block inward to release the fixing effect of the limit block and the slot, and then pulls the handle outward to make the handle drive the crushing rod to move outward along the inner wall of the cylinder, so that the inner end of the crushing rod fits with the inner wall of the cylinder, so that the crushing rod does not affect the subsequent cleaning work.

[0019] Then, by pulling down the outer rod, the block provided on the outer wall of the outer rod is separated from the bottom of the limit ring, thereby achieving the purpose of releasing the fixing effect of the outer rod, and by rotating the outer rod, the outer rod drives the two-way threaded rod to rotate, so that the two sets of moving blocks move vertically along the inner wall of the rotating shaft. At the same time, the moving block drives the two-way scraper to move outward along the stirring rod through the connecting rod, so that the outer side of the two-way scraper fits with the inner wall of the cylinder, and then by loosening the outer rod, the force of spring B drives the outer rod to reset upward for plugging and fixing, and then by starting the motor, the motor drives the rotating shaft and the two-way scraper to scrape and clean the inner wall of the cylinder.

[0020] The present invention provides a pulverizing device for producing fused magnesia with dust removal effect.
