Powered coal conveyor belt washing equipment

Abstract

The invention relates to powered coal conveyor belt washing equipment. The powered coal conveyor belt washing equipment comprises a washing device and a drying device which are arranged below a return belt, and is characterized in that the washing device comprises water nozzles and mud scraping rollers in sequence in the belt conveying direction; the water nozzles are connected with a spraying pipeline; the spraying pipeline is connected with a washing water source through pulse pumps; each mud scraping roller comprises a rotary drum; a driving device is connected with each rotary drum in a driving manner; a plurality of scraping plates are arranged on the surface of each rotary drum at intervals and radially distributed in the axial direction of the rotary drum; the length of each scraping plate is matched with the width of the return belt; the drying device is arranged at the downstream of the cleaning device, and comprises a ventilator arranged in the width direction of the return belt; a plurality of air outlets facing the return belt are arranged on the ventilator; the air inlet of the ventilator is connected with a draught fan; a water container used for collecting muddy water is arranged below the cleaning device and the drying device; a sewage draining outlet is arranged on the water container; and a spiral conveyor used for pushing mud is arranged at the bottom of the water container.

Description

technical field [0001] The invention relates to a pulverized coal conveying belt cleaning device. Background technique [0002] The belt conveyor can continuously convey materials on a predetermined route. Because of its large conveying capacity and long conveying distance, it is widely used, especially suitable for conveying and loading and unloading equipment for bulk materials. For example, the transportation of coal. [0003] As the coal will inevitably generate dust during the falling and transferring process, in order to avoid the raising of dust, water is usually sprayed on the conveyor belt, and the dust meets water to form mud, which falls on the belt and is transported downstream together. [0004] However, the mud falling on the belt will adhere to the rollers as the belt runs, causing the rollers to become thicker, corroding the rollers, and causing the belt to run off; The belt increases the difficulty of cleaning; not only the work intensity is high, but also...

Problems solved by technology

This patented technology can only partially clean the belt, and if a soft cleaning block is used, the cleaning effect is poor; if a hard cleaning block is used, the belt will be damaged

[0006] ZL201120178818.4 discloses a "Conveyor Belt Cleaning, Drying and Environmental Protection Cleaning Device", which installs a blowing device, a cleaning device, a filtering device, a rotating brush cleaning device and a supporting roller on the return belt; this scheme needs to add two supporting rollers and One drum, the whole device takes up a lot of space, a large amount of circulating water, and high power consumption
