Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0026] This application discloses a dust suppression component based on a coal slime conveyor. (Refer to...) Figure 1 and Figure 7A dust suppression component based on a coal slurry transfer machine includes a conveying device 1, a moving device 2 at the bottom of the conveying device 1, a spiral feeding device 3 on the surface of the conveying device 1, and a protective mechanism 4 on the top of the conveying device 1 (three in total). A spray dust suppression mechanism 5 is also provided on the surface of the conveying device 1. The conveying device 1 includes a conveyor wheel, a conveyor belt, and a drive motor. The drive motor drives the conveyor wheel to rotate, thereby driving the conveyor belt to transport the coal slurry. The moving device 2 includes a tracked moving machine. An internal engine of the tracked moving machine drives the track to rotate, achieving the moving function. The tracked moving machine and the conveying device 1 are connected by a rotating shaft and a cylinder telescopic rod. The extension and retraction of the cylinder drives the conveying device 1 to rotate around the rotating shaft, achieving the angle adjustment function of the conveying device 1. The spiral feeding device 3 includes a spiral roller, a drive motor, a drive rod, and a transmission belt. The drive motor drives the drive rod to rotate, thereby driving the transmission belt to drive the spiral roller. The spiral roller transports the coal slurry to the conveyor belt of the conveying device 1, and the conveyor belt transports and transfers the coal slurry. All of the above are existing technologies and will not be elaborated upon in this case.

[0027] The protective mechanism 4 includes a semi-circular fixed cover 401. The bottom of the semi-circular fixed cover 401 is fixedly connected to the top of the conveying device 1. A movable cover 402 is movably connected to the inner cavity of the semi-circular fixed cover 401. A sliding column 409 is fixedly connected to the surface of the movable cover 402. There are two sliding columns 409. The surface of the sliding column 409 is movably connected to the inner cavity of the semi-circular fixed cover 401.

[0028] Reference Figure 5 and Figure 6 The inner cavity of the semicircular fixing cover 401 is provided with a sliding groove 408. There are two sliding grooves 408. The inner cavity of each sliding groove 408 is movably connected to the surface of a sliding column 409. The inner cavity of each sliding groove 408 is fixedly connected with a limiting block 411. The sliding groove 408 is used to guide the sliding column 409 when it slides in the inner cavity of the semicircular fixing cover 401. The limiting block 411 is used to block and restrict the movement of the sliding column 409 when it contacts the surface of the limiting block 411, so as to prevent the sliding column 409 from leaving the inner cavity of the semicircular fixing cover 401.

[0029] Reference Figure 6 A damping sleeve 410 is fixedly sleeved on the surface of the sliding column 409. The damping sleeve 410 is made of rubber. The surface of the damping sleeve 410 contacts the inner cavity of the sliding groove 408. By setting the damping sleeve 410, the friction between the sliding column 409 and the inner cavity of the sliding groove 408 is increased, which indirectly avoids the movable cover 402 from sliding too fast in the inner cavity of the semi-circular fixed cover 401 and causing danger.

[0030] Reference Figure 3 and Figure 4Two fixed posts 403 are fixedly connected to the surface of the movable cover 402. One end of the fixed post 403 is fixedly connected to a fixed circular plate 406. A snap-fit ​​rod 404 is rotatably connected to the surface of the fixed post 403. A snap-fit ​​block 407 is snapped onto the surface of the snap-fit ​​rod 404. The surface of the snap-fit ​​block 407 is fixedly connected to the surface of the conveying device 1. The fixed posts 403, snap-fit ​​rod 404, fixed circular plate 406 and snap-fit ​​block 407 work together. When the movable cover 402 slides out of the inner cavity of the semi-circular fixed cover 401 and comes into contact with the surface of the conveying device 1, the snap-fit ​​rod 404 can be rotated to snap into the inner cavity of the snap-fit ​​block 407, thereby indirectly limiting the sliding movable cover 402.

[0031] Reference Figure 4 A torsion spring 405 is fitted on the surface of the fixed column 403. One end of the torsion spring 405 is fixedly connected to the surface of the snap-fit ​​rod 404, and the other end of the torsion spring 405 is fixedly connected to the surface of the fixed circular plate 406. Through the setting of the torsion spring 405, due to the elastic torque of the torsion spring 405, the snap-fit ​​rod 404 is always driven to rotate by the torsion spring 405 without being affected by external force, so that the snap-fit ​​rod 404 is always snapped into the inner cavity of the snap-fit ​​block 407.

[0032] Reference Figure 2 The spray dust suppression mechanism 5 includes a water storage tank 503, the surface of which is fixedly connected to the surface of the conveying device 1. A water pump 506 is fixedly connected to the surface of the water storage tank 503. The input end of the water pump 506 is fixedly connected to the inner cavity of the water storage tank 503, and the output end of the water pump 506 is fixedly connected to a water delivery pipe 505. One end of the water delivery pipe 505 is fixedly connected to an arc-shaped chamber 501, the surface of which is fixedly connected to the surface of the conveying device 1. The inner cavity of the arc-shaped chamber 501 is fixedly connected to a mist sprayer. There are several nozzles 502, which work together with the arc-shaped chamber 501, the mist nozzles 502, the water storage chamber 503, the water supply pipe 505 and the water pump 506. The water pump 506 draws water from the inner cavity of the water storage chamber 503 through its input end and then delivers it to the inner cavity of the water supply pipe 505 through its output end. Finally, the water enters the inner cavity of the arc-shaped chamber 501 and is sprayed out by the mist nozzles 502 to spray dust at the position where the coal slurry is transported by the conveying device 1 to the highest point and falls.

[0033] Reference Figure 2 The top of the water storage tank 503 is fixedly connected with a snap fastener 504. There are several snap fasteners 504. The inner cavity of the snap fastener 504 snaps into the surface of the water supply pipe 505. The snap fastener 504 is used to snap and limit the position of the water supply pipe 505 to prevent the water supply pipe 505 from shaking due to its excessive length.

[0034] Reference Figure 7The inner cavity of the water storage tank 503 is fixedly connected to a guide platform 507. The guide platform 507 is set at an angle and its lowest point is located at the lowest point of the water pump 506 input end. The guide platform 507 guides the water inside the water storage tank 503, so that even when the water storage tank 503 is in a horizontal state, the water inside can be smoothly drawn by the input end of the water pump 506.

[0035] Working principle: When coal slurry needs to be transferred, the moving device 2 will first move to a suitable position, and then the screw feeder 3 will start working. The screw feeder 3 will transport the coal slurry to the conveyor belt of the conveying device 1 through the screw plate of the screw feeder 3. The conveying device 1 will then transport the coal slurry. During the process of the conveying device 1 transporting the coal slurry, dust will be generated. At this time, the movable cover 402 needs to be pulled in sequence. The movable cover 402 will drive the sliding column 409 to slide in the inner cavity of the semi-circular fixed cover 401, so that the movable cover 402 slides out of the inner cavity of the semi-circular fixed cover 401 until the sliding column 409 drives the damping sleeve 410 to contact the limit block 411. At the same time, the surface of the movable cover 402 will contact the surface of the conveying device 1, and the locking rod 4 will be rotated. 04. The locking rod 404 drives the torsion spring 405 to twist. When the locking rod 404 is released, the elastic torque of the torsion spring 405 causes the surface of the locking rod 404 to engage with the inner cavity of the locking block 407, thereby limiting the sliding movable cover 402. When the coal slurry is transported to the top by the conveying device 1 and falls, the water pump 506 starts to work. The water pump 506 draws water from the water storage tank 503 through its input end and delivers it to the water supply pipe 505 through its output end. The water is then delivered to the inner cavity of the arc-shaped tank 501 through the water supply pipe 505 and sprayed out by the mist nozzle 502 to reduce the dust generated by the coal slurry falling from the highest point of the conveying device 1, preventing excessive dust from being scattered and inhaled by the surrounding workers.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
