[0023] The impurity removal mechanism 5 includes an impurity removal frame 51 fixedly connected to the inner wall of the housing 1. Two symmetrically positioned electric telescopic rods 52 are fixedly connected to the inner wall of the housing 1. A sealing plate 53, which is sealed to the inner wall of the bottom of the impurity removal frame 51, is fixedly connected to the telescopic ends of the two electric telescopic rods 52. A movable rod 54 is rotatably connected to the inner wall of the impurity removal frame 51. A reduction motor 55 for driving the movable rod 54 is provided on the outer wall of the housing 1. Multiple evenly distributed spiral blades 56 are provided on the rod wall of the movable rod 54. A stirring rod 5 is rotatably connected to the inner wall of the collection box 3. 7. The end of the stirring rod 57 away from the collection box 3 passes through the inner wall of the box 1 and is connected to the movable rod 54 through the transmission belt. It can simultaneously stir the wastewater after impurity removal to prevent the accumulation of impurities in the wastewater. Two symmetrical buffer blocks 13 are fixedly connected to the inner wall of the box 1, and the two buffer blocks 13 are located directly below the feed hopper 2. The lower surfaces of the two buffer blocks 13 are fixedly connected to a rubber plate 14, which can effectively buffer the impact force generated when the coal is fed and prevent damage to the filter frame 7.
[0024] Two symmetrical slide rails 6 are fixedly connected to the inner wall of the housing 1. A filter frame 7 is slidably connected to the inner wall of the two slide rails 6. A baffle 8 is fixedly connected to the lower surface of each of the two slide rails 6. An elastic sleeve 9 is movably connected to the upper surface of the baffle 8 and the lower surface of the filter frame 7. Two symmetrical water collection hoods 10 are provided on the inner wall of the top of the housing 1. Multiple evenly distributed nozzles 11 are provided on the inner wall of each of the two water collection hoods 10. A pump 12 is provided on the outer wall of the housing 1. The drain end of the pump 12 is connected to the inner wall of the two water collection hoods 10 through a flexible hose. A water pump 15 is provided on the outer wall of the drain pipe 4. A PLC controller 16 is provided on the outer wall of the housing 1. The geared motor 55, the pump 12 and the water pump 15 are all electrically connected to the PLC controller 16. The vibration generated by the multiple elastic sleeves 9 can accelerate the filtration speed of the filter frame 7, thereby improving the impurity removal efficiency of the impurity removal device.
[0025] The working principle of this utility model is as follows:
[0026] Coal enters the housing 1 through the feed hopper 2. The buffer block 13 and rubber plate 14 below the feed hopper 2 can buffer the impact of the falling coal and avoid damage to the impurity removal frame 51. When the PLC controller is turned on, the pump 12 delivers water to the water collection hood 10 and sprays it out through the nozzle 11 to initially wash the coal. Simultaneously, the telescopic end of the electric telescopic rod 52 extends to push the sealing plate 53, forming a watertight solid frame with the impurity removal frame 51. Then, the reduction motor 55 drives the movable rod 54 to rotate, and the spiral blades 56 on its rod wall agitate the coal and water, ensuring full contact between the coal and water flow, stripping away surface impurities, and ensuring thorough cleaning. After agitation, the two electric telescopic rods 52 are reversed, causing the sealing plate 53 to detach from the impurity removal frame 51. At this point, the wastewater and coal in the impurity removal frame 51 fall into the filter frame 7. The force generated when the coal falls causes multiple elastic sleeves 9 to deform elastically, further improving the screening effect of the filter frame 7. When the movable rod 54 rotates, it drives the agitator 57 in the collection box 3 to rotate synchronously via the transmission belt, agitating the wastewater after impurity removal and preventing impurities from settling and accumulating. The filter frame 7 accelerates its filtration speed with the vibration assistance of the elastic sleeves 9. The coal remains inside the filter frame 7, and the wastewater is discharged through the drain pipe 4. The water pump 15 on the drain pipe 4 controls the drainage speed and flow rate. The filtered coal can be removed from the filter frame 7.
[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
