DETAILED DESCRIPTION

[0016] The specific contents of the utility model are further described below:

[0017] The utility model installs the device below the return position of the conveyor, uses underground dust-proof water to flush the bottom surface of the lower belt, and uses a tension spring type cleaning scraper to directly scrape the bottom surface of the lower belt after flushing. At the same time, a small sedimentation tank is constructed below to facilitate the centralized recovery and sedimentation of the scraped sewage to prevent pollution of the machine path.

[0018] A specific conveyor belt surface cleaning device in a coal tunnel includes a nozzle 2 facing the lower side of the conveyor belt, a pressure water pipe 3 and a cleaning scraper 1, the nozzle 2 is connected to the pressure water pipe 3, the cleaning scraper 1 is located at the rear of the nozzle 2, and includes a scraper 11, a cleaning scraper frame 12 and a mounting frame 13. The mounting frame 13 is divided into two groups, which are respectively fixed on both sides of the frame of the belt conveyor. The two ends of the cleaning scraper frame 12 are fixed on the mounting frame 13, and the scraper 11 is fixed on the cleaning scraper frame 12. The scraper 11 contacts the lower side of the conveyor belt and is inclined toward the running direction of the belt.

[0019] The pressurized water pipe 3 includes a cleaning water pipe 32 connected to an underground dust removal and fire fighting main pipe 31, on which a first solenoid valve 33, a front water distribution pipe 34, a solenoid valve 35, a rear water distribution pipe 36 and a nozzle 2 are arranged in series, a backup control water pipe 37 is arranged on the branch of the front water distribution pipe 34 and the rear water distribution pipe 36, a manual valve 38 is arranged on the backup control water pipe 37, and the solenoid valve 35 is controlled by a PLC.

[0020] The pressurized water pipe is a dust-proof pressurized water pipe on site, which is guided to the conveyor through the cleaning water pipe. The control methods of the water spray system are divided into automatic control method and manual control method. The automatic control method is to control the start and stop of the water source through the solenoid valve. When the conveyor receives the start and stop signal, the on-site control system PLC control cabinet sends out instructions at the same time, and the stop valve acts synchronously to achieve the start and stop synchronization of the water spray system and the belt conveyor.

[0021] The manual control method is to manually operate the manual valve on site to control the start and stop of the water source to achieve the start and stop of the water spray system.

[0022] The mounting frame 13 in the sweeper of the device includes a screw, an elastic member and a connecting plate. The screw is passed through holes on both sides of the conveyor. The elastic member is sleeved on the screw and is located above the conveyor frame. A nut is provided on the screw on the upper part of the elastic member. The lower part of the screw is connected to the horizontal part of the connecting plate. The vertical part of the connecting plate is connected to the cleaning scraper frame 12. The cleaning scraper frame 12 is long enough to span the lower part of the conveyor belt and is provided with fixing holes to fix the scraper 11.

[0023] In order to ensure that the surface of the tape is cleaned in time, the cleaning scraper uses a poly-grease cleaning scraper and an elastic part to ensure that the cleaning scraper is always in close contact with the surface of the tape. At the same time, multiple cleaners can be added according to the on-site cleaning effect.

[0024] The sedimentation tank is arranged directly below the scraper 11 and its width is greater than the length of the scraper 11, so as to centrally clean the scraped sewage and sludge.

[0025] After using the hydraulic decontamination device, each belt conveyor can reduce the number of cleaning personnel by one. The mine uses this device to save 7,200 yuan in labor costs per belt conveyor each year. The application of this device can ensure that the surface of the belt is cleaned and extended the service life of the belt and roller.
