Special feeding groove for wet coal spiral screening machine

Abstract

The invention discloses a special feeding groove for a wet coal spiral screening machine. The special feeding groove for the wet coal spiral screening machine comprises a feeding groove body; the feeding groove body consists of a vertical through groove way and an inclined groove way; the vertical through groove way is vertically arranged; the inclined groove way is aslant downwards guided below the vertical through groove way; an internal feed hopper is mounted at an opening end of the upper end of the vertical through groove way; electric heating plates are paved on a back end channel of thevertical through groove way and a lower end channel of the inclined groove way; a coal dust content detector is mounted on the inner wall of a front end channel of the vertical through groove way; analarm device is arranged at the external of the feeding groove body; and the coal dust content detector is in wireless induction connection with the alarm device. Through the mode, the feeding groovecan be special used for the screening work of wet coals; rising moisture can be heated by the electric heating plates to improve the coal quality; the internal feed hopper can prevent coal dust fromflying for discharge; and the coal dust content detector can detect signals of bad coal dust to transfer to the alarm device for alarming.

Description

technical field [0001] The invention relates to the field of coal separators, in particular to a special feeding trough for a wet coal spiral screen. Background technique [0002] Raw coal is inevitably mixed with impurities in the process of generation, mining and transportation; and with the deepening of mining, the quality of raw coal is getting worse. In order to reduce impurities in raw coal, effectively and rationally utilize coal resources, and divide coal into various products according to quality and specifications, it is necessary to process coal mechanically. These machines are commonly called coal washing equipment. The coal separator is only one type of washing equipment. [0003] Coal preparation machines are divided into jigging, flotation, dense medium coal preparation, washing, etc. Coal preparation machines include raw coal gangue discharge machines, gangue coal lifters, and multi-functional coal preparation machines. Generally speaking, the coal preparat...

Problems solved by technology

[0004] The coal separator is often equipped with a feeding chute at the front end to pour coal into, while the traditional feeding chute is just a simple channel for coal to enter, lacking functions such as drying coal and preventing coal dust from flying, which reduces the good use
