Anti-freezing dust suppression device for belt

Abstract

The invention relates to an anti-freezing dust suppression device for a belt. The anti-freezing dust suppression device for the belt comprises a heating assembly, a conveying assembly and a spraying assembly; one end of the conveying assembly is connected with the heating assembly, the other end of the conveying assembly is connected with the spraying assembly, and the spraying assembly is locatedabove the belt. The device solves the problem of influence of sticking of coal on production during belt operation in winter from the source, a great anti-freezing effect is achieved, the returned belt after coal transportation is clean, automatic control over a machine to prevent freezing is achieved, manpower and material resources are saved, and all kinds of potential safety hazards brought bymanual cleaning are avoided; at the same time, the device solves the problem of dust suppression of the outdoor belt in winter, and flying of coal dust is effectively suppressed, so that environmental protection requirements for a production environment are met, and the gap in the field is filled up; investment of equipment is small, small space is occupied, and convenience is provided for popularization.

Description

technical field [0001] The invention belongs to the technical field of coal flow dust control, and in particular relates to a belt antifreeze sticky dust suppression device. Background technique [0002] In winter, the outdoor temperature in the cold northern region is below zero, and the belt conveyor rollers and belts running outdoors in open-pit mines and power plants are exposed outdoors, and the temperature is the same as the outdoor ambient temperature, which is below zero. The coal under the open pit is dug out by an electric shovel. Due to the thick coal seam, except for the surface temperature below zero, the others are above zero. Crusher system, after being crushed, it enters the belt system and transports it to the designated place. When the hot coal above zero is broken and enters the belt below zero, the coal powder on the surface of the belt conveyor will stick to the surface of the belt due to the temperature difference between cold and hot. The pulverized ...

AI Technical Summary

Problems solved by technology

Roller sticky coal is cleaned by scraper or spiral cleaner, and these are all cleaning methods after coal sticking, there is no way to solve the belt non-sticky coal at the source

As for the treatment method of dust suppression, the traditional wet dust removal method cannot be used due to the low outdoor ambient temperature in winter in the north.

Due to the difference in temperature between hot and cold, the coal powder is frozen and stuck to the cloth belt, and cannot be removed by vibration and pulse blowing, so it cannot be used in winter

At present, there is basically no dust suppression method for outdoor belt conveyors in cold northern regions, all of which are due to the state of free dust spraying, which seriously pollutes the environment
