Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figure 1 - Figure 2 shown, this embodiment provides a dust suppression spray device for a coal preparation plant, including a support frame and a number of nozzle assemblies arranged on the support frame.

[0031] Specifically, the support frame 1 includes a top plate 11, a bottom plate 12 and four columns 13. The four columns 13 are distributed at the four corners, with their tops fixedly connected to the lower end surface of the top plate 11 and their bottoms fixedly connected to the upper end surface of the bottom plate 12. Connecting ears 14 are also fixedly connected to the four corners of the bottom plate 12 and are fixed at a higher position in the coal preparation plant through the connecting ears 14, for example, fixed at the highest position of the conveyor in the coal preparation plant. A water tank 2 is arranged on the bottom plate 12. The water tank 2 is sequentially connected with an atomizing water pump 3, a booster water pump 4 and a connecting water pipe 5. The connecting water pipe 5 extends and passes through the top plate 11 and is connected to the main pipe 6 arranged on the top plate 11. The main pipe 6 is connected with a number of shunt pipes 7. The atomizing water pump 3 sucks and atomizes the water in the water tank 2, enters the connecting water pipe 5 through the booster water pump 4, then enters the main pipe 6, and then enters the nozzle through the shunt pipe 7 to form a spray, achieving the purpose of dust suppression spray in the coal preparation plant.

[0032] In this embodiment, as Figure 1 - Figure 6As shown in the figure, a number of spray head assemblies 8 are arranged on the top plate 11 of the support frame 1. Each spray head assembly 8 is connected to a shunt pipe 7, and the shunt pipe 7 is a flexible hose body connected to the main pipe. Among them, the spray head assembly 8 includes a spray head 81, a rigid pipe body 82 connected to the spray head 81, a limiting member 83 clamped on the outer wall of the rigid pipe body 82, and a support 84 for erecting the rigid pipe body 82 and the limiting member 83. The upper part of the support 84 is provided with a number of placement grooves, and the rigid pipe body 82 can be placed in different directions, so as to form a spray head layout in different directions.

[0033] Furthermore, the support 84 includes a support column 841 fixed to the bottom plate 12 and a support disc 842 fixed to the support column 841. The support column 841 is in the shape of a cuboid, and a groove 843 is opened at the central position of its top; the support disc 842 is in a circular ring shape, and a number of circumferentially distributed placement grooves 844 are opened on one side of the support disc 842, and each placement groove 844 penetrates through the center of the support disc 842. In this embodiment, 12 placement grooves 844 are provided, and the included angles between adjacent placement grooves 844 are the same.

[0034] The limiting member 83 includes two hoop bodies 831 sleeved on the outer wall of the rigid pipe body 82 and a limiting rod 832 fixed to the outer side surface of the hoop body 831. The two hoop bodies 831 are connected by bolts. The two limiting rods 832 are located in the placement groove 844, and the limiting rod 832 extends a certain distance beyond the edge of the placement groove 844, which is convenient for the binding rope to limit the limiting rod 832;

[0035] In this embodiment, the two hoop bodies 831 in the limiting member 83 are clamped on the rigid pipe body 82. At this time, the limiting member 83 is perpendicular to the rigid pipe body 82. Then, the limiting member 83 and the rigid pipe body are placed into the placement groove 844. At this time, two placement grooves 844 passing through the center of the support disc 842 and located on the same straight line are used to place the two limiting rods 832, and the other two placement grooves 844 passing through the center of the support disc 842 and located on the same straight line are used to place the rigid pipe body 82. The two hoop bodies 831 are exactly located at the center of the ring of the support disc 842. When the two limiting rods 832 of the spray head are placed vertically, the bottom end of the lower limiting rod 832 extends into the groove 843 of the support 841.

[0036] In order to fix the limiting member 83 and the rigid pipe body 82 to the limiting disc, the limiting rod 832 can also be tied to the support disc 842 by a binding rope 9. Among them, the binding rope 9 is an annular rope body, and the rope body is a rope body with elasticity. A hoop member can also be provided in the middle of the binding rope.

[0037] The dust suppression spray device for a coal preparation plant provided in this embodiment sucks and atomizes the water in the water tank 2 through the atomizing water pump 3, enters the connecting water pipe 5 through the booster water pump 4, then enters the main pipe 6, and then enters the spray head through the shunt pipe 7 to form a spray. By adjusting the directions of the spray heads 81 respectively through each spray head assembly 8, the requirements for different dust suppression spray directions in the coal preparation plant can be met.

[0038] Before adjusting the nozzle, the limiting member 83 is clamped on the rigid pipe body 82 through the hoop body 831 at the middle position of the rigid pipe body 82. The two limiting rods 832 and the rigid pipe body perpendicular thereto are placed in the grooves 843 in the corresponding directions, and then the binding ropes 9 are respectively sleeved on the two end positions of the two limiting rods 832 extending out of the edge of the support plate. Since the binding ropes are annular elastic ropes, the limiting rods 843 can be fixed on the support plate 842 by the elastic force of the binding ropes themselves. When the direction of the nozzle needs to be adjusted, the binding rope 9 is removed, and then the limiting member 83 and the rigid pipe body 82 are removed from the original placement groove 844 and placed in the new placement groove 844 corresponding to the required direction, and then the binding rope 9 is used to sleeve on the two end positions of the limiting rod 832 extending out of the edge of the support plate to achieve fixation, so as to change the direction of the dust suppression spray.

[0039] Since the shunt pipe 7 connecting the rigid pipe body 82 and the main pipe 6 is designed as a flexible pipe, when the nozzle at the end of the rigid pipe body 82 is adjusted in direction, the operation of adjusting the direction will not be hindered.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
