Description

Technical Field

[0001] The utility model relates to a water mist roller brush cleaning device. Background Art

[0002] When the belt conveyor is transporting coal on the return journey, a large amount of fine dust adheres to the working surface. When it passes through the return rollers and various guide rollers, or when the load and tension of the belt change during operation, the belt vibrates, causing a large amount of dust. As the dust accumulates, the belt conveyor components wear out prematurely.

[0003] The existing belt cleaner can only use a scraper to simply clean the remaining coal carried by the return end of the belt. Since the coal contains moisture, it will stick to the belt. If it is not cleaned, it will continue to fall after colliding with the return roller during the operation of the belt, causing dust to float. Utility Model Content

DETAILED DESCRIPTION

[0019] Reference Figures 1-4 A water mist roller brush cleaning device, which comprises a bracket 4, on which a water mist spraying device, an electric roller brush and two scrapers are connected in sequence from front to back, and the scrapers are polyurethane scrapers;

[0020] The return section of the coal conveyor belt is cleaned in three steps. The first step is to spray and flush the working surface of the return end of the belt through the nozzle on the front end nozzle, and then clean it through the front scraper 3; the second step is to spray and flush the working surface of the return end of the belt through the nozzle on another nozzle, and after flushing, the belt is deeply cleaned by the electric roller brush; the third step is to remove water from the working surface of the belt by the rear scraper, which can ensure the comprehensive cleaning of the return section of the coal conveyor belt and ensure the cleaning effect.

[0021] The water mist spraying device includes a main water pipe 8, which is connected to a tee 10. The two outlet ends of the tee are respectively connected to branch pipes 9. Each branch pipe is fixed to the nozzle 5 through a flange 14. The nozzle has multiple nozzles 6 in the length direction. The nozzle passes through the through hole on the side panel of the bracket. The diameter of the through hole is slightly larger than the diameter of the nozzle, so that the nozzle can be effectively supported without affecting the adjustment of the nozzle angle.

[0022] The flange of the nozzle and the flange of the branch pipe are respectively provided with slots 13, and sealing rings 12 are installed in the slots;

[0023] A valve 7 is installed on each branch pipe. The flange of the nozzle and the flange on the branch pipe respectively have four arc-shaped notches 20 arranged in a circle. The fixing bolts pass through the arc-shaped notches to fix the two flanges. When the angle of the nozzle needs to be adjusted, the fixing bolts need to be loosened, and then the nozzle is rotated to change the direction of the nozzle. After adjustment, the fixing bolts can be tightened.

[0024] The electric roller brush includes a driving motor 17 , the output shaft of the driving motor is fixed to a roller brush shaft 16 , and a roller brush 2 is fixed on the roller brush shaft.

[0025] In the water mist roller brush cleaning device, the bracket includes two side plates 19 , which are fixedly connected by a connecting rod 18 .

[0026] In the water mist roller brush cleaning device, the flange of the nozzle and the flange on the branch pipe are respectively provided with slots 13, and sealing rings 12 are installed in the slots.

[0027] The return section of the coal conveyor belt is cleaned through three steps. The valve on each branch pipe is opened, and the external high-pressure water enters through the main water pipe and then enters each branch pipe, and then enters the nozzle, and sprays water mist through the nozzle on the nozzle. The drive motor is started, and the two ends of the roller brush shaft are connected to the side plates of the bracket through bearings. The roller brush is fixed on the roller brush shaft. Figure 2 The return section of the coal conveyor belt shown moves from left to right, and the rotation direction of the roller brush is counterclockwise, which can clean the return section of the coal conveyor belt. The first part uses the nozzle on the nozzle located at the front end to spray and flush the working surface of the belt return end, and then cleans it through the front scraper 3; the second part uses the nozzle on the other nozzle to spray and flush the working surface of the belt return end, and after flushing, the belt is deeply cleaned by the electric roller brush; the third part uses the rear scraper to perform the final water removal on the belt working surface, which can ensure that the return section of the coal conveyor belt is fully cleaned and the cleaning effect is guaranteed.
