Description

Technical Field

[0001] The utility model belongs to the technical field of coal washing, in particular to a nozzle structure of a raw coal wetting device. Background Art

[0002] Coal washing is an indispensable process in coal deep processing. Coal mined directly from the mine is called raw coal. Raw coal is mixed with many impurities during the mining process, and the quality of coal is also different. Coal with low internal ash content and coal with high internal ash content are mixed together. Coal washing is an industrial process to remove impurities from raw coal or to classify high-quality coal and low-quality coal.

[0003] After long-term observation, it was found that the tubular nozzle of the original wetting device had a small spray area and could not fully wet the raw coal, resulting in local raw coal clumping, resulting in poor cyclone sorting accuracy, and high clean coal gangue rate, resulting in unstable clean coal indicators and reduced yield. Therefore, a nozzle structure for a raw coal wetting device is needed. The duckbill wetting device can have a large fan-shaped wetting area to fully wet the raw coal and make the raw coal sufficiently loose, avoiding the clumping of the raw coal and affecting the subsequent dispersion. At the same time, by installing a cover on the surface of the duckbill nozzle, the influence of external wind on the spraying effect can be avoided. Utility Model Content

[0004] The purpose of the utility model is to provide a nozzle structure of a raw coal wetting device. Through the duckbill wetting device, the fan-shaped wetting area is large, so that the raw coal is fully moistened and made sufficiently loose, avoiding the raw coal from agglomerating and affecting the situation that it is too late to disperse in the later stage. At the same time, by installing a cover on the surface of the duckbill nozzle, the influence of external wind force on the spraying effect can be avoided, so as to solve the technical problems raised by the above-mentioned background technology.

[0005] The utility model solves the above-mentioned technical problems with a technical solution as follows: a nozzle structure of a raw coal wetting device, comprising a box body: the top of the box body is connected to a liquid inlet pipe, the bottom of the liquid inlet pipe is connected to a duckbill nozzle, a frame body is fixedly installed on the surface of the box body, a control box and a carrier plate are fixedly installed on the surface of the frame body, a wind speed sensor and a motor are fixedly installed on the surface of the carrier plate by bolts, the output shaft of the motor is fixedly connected to a threaded rod by a flange, a track groove is welded on the bottom of the box body, two symmetrically arranged shaft rods are rotatably connected to the bottom of the box body, a gear and a side plate shell are fixedly installed on the surface of the shaft rod, two symmetrically arranged T-shaped sliders are slidably connected to the inner wall of the track groove, a threaded ring is threadedly connected to the surface of the threaded rod, a support rod is rotatably connected between the threaded ring and the T-shaped slider through a rotating shaft, and two T-shaped racks are symmetrically arranged on the outer side of the track groove.

[0006] Preferably, the frame is fixedly installed above the conveyor belt machine by bolts, and the liquid inlet pipe is connected to an external medium liquid pipeline.

[0007] Preferably, the rear side of the T-shaped slider extends to the outside of the track groove, and the bottom of the T-shaped rack is fixed to the T-shaped slider by bolts.

[0009] Preferably, a wear-resistant layer is provided on the inner wall of the box body, and the wear-resistant layer is a corundum layer.

[0010] Preferably, the wind speed sensor and the motor are electrically connected to the control box via wires.

[0025] Working principle: When the utility model is used, the user changes the wetting tube into a box structure, and the box nozzle is in the shape of a flat fan blade, and the fan-shaped wetting area is large. After the medium liquid enters the box 1 through the liquid inlet pipe 2, the medium liquid is then guided by the duckbill nozzle 3 to become a fan shape and wet the raw coal, so that the raw coal is fully wetted and loosened. At the same time, when the external wind speed is large, the wind speed sensor 7 transmits a signal to the control box 5, so that the control box 5 controls the motor 8 to drive the threaded rod 9 to rotate, and then the threaded rod 9 passes through the threaded ring 15 and the support rod 1 6 drives the T-shaped slider 14 to move in the inner wall of the track groove 10, so that the T-shaped slider 14 drives the gear 12 to rotate through the T-shaped rack 17, and then the gear 12 drives the side plate shell 13 to close through the shaft 11 and cover the duckbill nozzle 3, so that the side plate shell 13 wraps the side of the duckbill nozzle 3 to prevent the wind from affecting the fan-shaped medium liquid sprayed from the duckbill nozzle 3, so that the raw coal is fully wetted and made sufficiently loose. At the same time, by installing a cover on the surface of the duckbill nozzle, the external wind can be prevented from affecting the spraying effect.

[0026] In summary: the nozzle structure of the raw coal wetting device is achieved by changing the wetting tube into a box structure, and the box nozzle is in the shape of a flat fan blade with a large fan-shaped wetting area, so that the raw coal can be fully wetted and made sufficiently loose. At the same time, the signal is transmitted to the control box 5 through the wind speed sensor 7, so that the control box 5 controls the motor 8 to make the side plate shell 13 wrap the side of the duckbill nozzle 3 to prevent the wind from affecting the fan-shaped medium liquid sprayed from the duckbill nozzle 3, so that the raw coal can be fully wetted and made sufficiently loose. At the same time, by installing a cover on the surface of the duckbill nozzle, the purpose of preventing the external wind from affecting the spraying effect can be achieved.
