When cleaning, it is best to pump out the water first and then clean the sludge. However, when pumping water, the coal sludge can easily block the water pump and affect the efficiency of pumping. Although the water inlet end of the water pump often uses a filtering structure to prevent sand and sludge from entering, it is still easy to be blocked after long-term use, affecting the efficiency.

DETAILED DESCRIPTION

[0015] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0016] like Figures 1 to 6 As shown, the present invention provides an underground water bunker coal-water separation device, including a pipe body 1, a first shell body 2 is arranged at the lower end of the pipe body, the upper end of the first shell body 2 is open, the lower end of the pipe body extends into the upper end of the first shell body and is fixedly connected thereto, a plurality of filter plates 3 are annularly embedded in the bottom surface of the first shell body, a sedimentation tank 4 is fixedly installed in the middle of the bottom surface of the first shell body, a first waterproof motor 5 fixedly connected to the inside of the first shell body is arranged on the upper side of the sedimentation tank 4, the output shaft of the first waterproof motor 5 faces downward and passes through the bottom of the sedimentation tank, the lower end of the output shaft of the first waterproof motor is sleeved with a first sleeve ring 6 through a first unidirectional driving structure, the first sleeve ring is rotatably connected to the bottom of the sedimentation tank, a plurality of arc-shaped scrapers 7 are arranged on the outer periphery of the first sleeve ring through a connecting rod, the upper part of the scraper 7 is in contact with the bottom surface of the filter plate, and the first waterproof motor drives the first sleeve ring when in forward transmission. As the scraper rotates, the coal slime remaining on the bottom of the filter plate can be scraped off in time. A number of drain holes 8 are opened at the bottom of the sedimentation tank. A one-way valve plate 9 is installed at the lower end of the drain hole. One end of the one-way valve plate 9 is hingedly connected to one side of the lower end of the corresponding drain hole. A torsion spring is installed on the hinge shaft. A second ring is set on the output shaft of the first waterproof motor corresponding to the position in the sedimentation tank. The output shaft of the first waterproof motor is connected to the second ring through a second one-way driving structure. A number of blades 10 are installed on the outer periphery of the second ring. When the first waterproof motor is reversed, the first ring does not rotate with it, and the second ring and the blades rotate with the first waterproof motor, giving a downward impact force to the coal slime in the sedimentation tank. The coal slime can push the one-way valve plate 9 and be discharged to the outside of the drain hole. When the first waterproof motor rotates forward, the one-way valve plate automatically closes the drain hole under the action of the torsion spring.

[0017] A water pump 11 is installed inside the lower end of the pipe body, the bottom of the water pump is a water inlet, and the upper end of the water pump is connected to a water outlet pipe 12.

[0018] The second shell 13 is sleeved on the outside of the first shell, the lower end of the second shell 13 is open, the upper end of the second shell is sleeved on the outer periphery of the tube body and the two are rotatably connected, the inner wall of the lower end of the second shell is rotatably connected to the outer periphery of the first shell, and a plurality of vertical scrapers 14 are equidistantly arranged in an annular shape at the bottom of the second shell 13, and an angle C is acute between the meridian between the connection point of the scraper 14 and the second shell and the center axis of the second shell and the plate surface of the scraper.

[0019] The inner side of the upper part of the second shell is connected to the tube body through a driving device, which drives the second shell to rotate around the tube body. When the scraper 14 rotates accordingly, it drives the coal slime outward, reducing the coal slime at the filter plate position at the bottom of the first shell and reducing the filtering amount of the coal slime by the filter plate.

[0020] The vertical section of the scraper bar is arc-shaped, and a notch 15 is set at the bottom of the outer end of the scraper bar. The notch is located on the upper side of the scraper. When the scraper bar drives the coal slime on the bottom of the filter plate outward, the coal slime finally moves to the notch position and falls into the working area of ​​the scraper. The scraped coal slime can be driven outward through the scraper to prevent the coal slime from flowing back to the bottom of the filter plate again.

[0021] The scraper is divided into an upper fixed plate 141, which is fixedly connected to the bottom of the second shell body, and a sliding plate 142 that can move up and down is slidably arranged on the side of the fixed plate. The sliding plate 142 is connected to the fixed plate by an elastic member, and the elastic member is a downward elastic force of the sliding plate. The elastic member is an elastic telescopic rod 143, and the upper end of the elastic telescopic rod is fixedly connected to the side of the fixed plate, and the lower end of the elastic telescopic rod is fixedly connected to the side of the sliding plate.

[0022] The driving device includes a second waterproof motor 16 fixedly arranged on the side of the tube body. The interior of the second shell is connected to the tube body through a planetary reduction gear set, and the planetary reduction gear set is connected to the second motor. This is conventional technology and will not be repeated here. The purpose of this design is to stably drive the second shell to rotate.

[0023] A conical head 17 is fixedly mounted on the lower end of the first collar 6 .

[0024] Working principle: When in use, the device is placed as a whole into the bottom of the water tank through the tube body, so that the conical head 17 is against the bottom of the water tank, and the sliding plate 142 is attached to the bottom of the water tank. The second waterproof motor is started to drive the second shell and the scraper to rotate, and the scraper drives the coal slime in the area to the outside. The first waterproof motor drives the first ring and the scraper to rotate, so that the coal slime remaining on the bottom of the filter plate can be scraped off in time, and the scraped coal slime is driven to the outer area again by the scraper, so that a space with less coal slime can be formed in part of the lower part of the filter plate, and stable water pumping can be achieved at the bottom of the water tank with a large amount of coal slime without clogging the filter plate, thereby achieving long-term water pumping work.

[0025] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
