Special-purposed pulverizer for coal mine fire extinguishing high hygrophanous resin, and application method thereof

Abstract

The invention discloses a special-purposed pulverizer for a coal mine fire extinguishing high hygrophanous resin and an application method thereof. The invention is characterized in that: a material canister is fixed on a main rack, an outlet at the lower part of the material canister is connected with a chute feeder, a guide rail is fixed on the main rack, one end of the chute feeder is fixed with an electromagnetic device, the chute feeder is connected with the guide rail through a dovetail, the other end of the chute feeder is connected with the upper end of the feeding channel, the lower end of the feeding channel is connected with a through hole on a baffle plate, the baffle plate is fixed on a crushing chamber, subordinate blades are annularly arranged on the upper part of the crushing chamber, screen meshes are annularly arranged on the lower part of the crushing chamber, a motor is fixed on the main rack through a motor fixing rack, an output shaft of the motor is fixed on a flange of the crushing chamber, the terminal of the output shaft is fixed with a circular disc, several main blades are distributed around the circular disc. According to the invention, vibration feeding is adopted for feeding a stable and uniform way, and overload damage can be prevented though controlling of the motor current; the main blades and the subordinate blades have stronger flexibility to reduce the wearing of blades; the subordinate blades are annularly and densely arranged such that the crushing efficiency and quality can be enhanced; the screen meshes are convenient to be changed for different meshes of crushing.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a special pulverizer for coal mine fire extinguishing super absorbent resin and a method for using the same. Background technique [0002] A pulverizer is a device that pulverizes large-sized solid particles to the required size. There are four kinds of external forces applied to the solid in the crushing process: rolling, shearing, impact and grinding. Compression rolling is mainly used for coarse and medium crushing, suitable for the crushing of hard materials and bulk materials; shearing is mainly used for fine crushing, suitable for the crushing of tough materials; impact is mainly used for medium crushing, fine grinding and ultra-fine grinding, suitable for It is suitable for the crushing of brittle materials; grinding is mainly used for fine grinding and ultra-fine grinding, suitable for the crushing of small pieces and fine particles. [0003] For coal mine fire extinguishing super absorb...

AI Technical Summary

Problems solved by technology

The traditional crushing device has high precision and good crushing effect, but the cost of the device is high and the maintenance cost is high. The high-precision crushing machine means high requirements for the blades. Ordinary blades are easy to wear and break, and need to be replaced frequently
