Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, and specifically relates to a dust removal device for a dressing plant. Background Technique

[0002] A dressing plant is an important production unit in a mining enterprise. Generally, a dressing plant is built near the mining area to reduce transportation costs. Ore dressing is the most important link in the production of the entire mineral product and is a key department in a mining enterprise. In addition to the three main operations and equipment of mineral raw material preparation, screening before ore dressing, and product treatment after separation, a dressing plant is also equipped with an ore storage yard (also used for mixing ores), ore bins, transportation of products in the operation room (belt transportation, pulp pumping), feeders, medicine preparation rooms and medicine feeders in the flotation workshop, sampling machines, detection instruments, and automatic control facilities for the ore dressing process.

[0003] During the production process of a dressing plant, a large amount of dust will be generated and diffuse in the air. In order to avoid the harm to the human body caused by inhaling dust manually, a spray vehicle is used to perform dust removal operations on the dust in the air. However, when the spray vehicle sprays, the spray angle cannot be adjusted. At the same time, the spray vehicle is large in size and not easy to adjust the spray orientation, resulting in low efficiency of spray dust removal.

[0004] Therefore, it is of practical significance to develop a dust removal device for a dressing plant. Summary of the Invention

[0005] The task of the utility model is to overcome the existing deficiencies and provide a dust removal device for a dressing plant, which can not only adjust the rotation angle of the spray cylinder up or down, but also process the dust in different directions, effectively improving the dust removal efficiency of the dressing plant and having a simple structure.

[0006] To complete the above tasks, the present utility model adopts the following technical solutions:

[0007] A dust removal device for a dressing plant includes a spray dust removal device and a trolley; the spray dust removal device includes a spray cylinder supported by a support plate with a water adding hopper and a screen on the box body surface, a water pump facing upwards, a large gear disk sleeved, a water supply iron pipe with a hose, and an electric push rod with an arc-shaped slider at the bottom and a high-pressure nozzle sleeved, and a small gear disk with a motor and a protective cover meshing with the large gear disk and a base water supply system. The motor drives the rotation of the rotating shaft, and the small gear disk is linked to enable the spray cylinder to rotate in different directions. The lifting of the electric push rod can adjust the up and down angle of the spray cylinder. The base water supply system of the box body is provided with a water pump and a connected water supply iron pipe and a hose. The hose is connected to the high-pressure nozzle, and the water supply iron pipe injects water into the high-pressure nozzle through the hose, so that the incoming water is broken into tiny water droplets or water mist and is sprayed for dust removal from the spray cylinder nozzle by a fan. The trolley includes a bottom plate with several pulleys, and one end of the bottom plate is provided with a push rod with a control switch connecting the fan, the motor, and the water pump on it, which is convenient for pushing the spray dust removal device and controlling the all-round spray dust removal.

[0008] Compared with the prior art, the utility model has the following advantages or effects:

[0009] Since the large gear disk and the spray cylinder are respectively rotatably connected to both ends of the electric push rod, when the electric push rod extends or retracts, the arc-shaped slider slides obliquely upward inside the chute or slides towards the bottom of the chute, so that the angle of the spray cylinder can be adjusted up and down, so that water mist can be sprayed on dust at different heights; at the same time, since the large gear disk and the small gear disk are meshed with each other, and the motor drives the rotating shaft to rotate, the small gear disk drives the large gear disk to rotate, so that the spray cylinder rotates omnidirectionally, so that the dust in different directions can be adjusted and processed, effectively improving the dust removal efficiency of the ore dressing plant and having a simple structure. In addition, since a trolley is provided, the displacement is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The motor 16 drives a rotating shaft 18 to rotate, and the small gear disk is linked, so that the spray cylinder 12 can rotate in all directions. The electric push rod 8 can adjust the up and down angle of the spray cylinder 12. The base water supply system of the box body 4 is provided with a water pump 19 and a connected water supply iron pipe 9 and a hose 10. The hose 10 is connected to the high-pressure nozzle 14. The water supply iron pipe 9 injects water into the high-pressure nozzle 14 through the hose 10), so that the incoming water is broken into tiny water droplets or water mist, and dust is removed by spraying from the nozzle of the spray cylinder 12 through a fan 13. The trolley includes a bottom plate 1 with several pulleys 2. One end of the bottom plate 1 is provided with a push rod 3 with a control switch connecting the fan 13, the motor 16, and the water pump 19 on the top, which is convenient for pushing the spray dust removal device and controlling the all-round spray dust removal.

[0019] The present utility model can be further as follows:

[0020] At the center of the top of the large gear disk 7, a top connecting hose 10 and a water supply iron pipe 9 are arranged.

[0021] One end of the top of the large gear disk 7 is rotatably connected to the electric push rod 8. The top of the electric push rod 8 is provided with a rotating connection seat 801 with an arc-shaped slider 802.

[0022] One end inside the spray cylinder 12 is provided with a fan 13, and a sliding groove 121 slidably connected to the arc-shaped slider 802 is opened at the bottom of the spray cylinder 12.

[0023] A screen 6 is arranged inside the water adding hopper (5). The lower part of the screen 6 is communicated with the inside of the box body 4, which can quickly inject water into the box body 4 and prevent impurities from entering the box body 4.

[0024] One end of the water supply iron pipe 9 penetrates through the center of the top of the large gear disk 7 and the bottom of the box body 4, extends into the box body 4 and is rotatably connected to the discharge port of the water pump 19. The water supply iron pipe 9 and the top of the box body 4 are rotatably connected through a bearing, and the water supply iron pipe 9 is fixedly connected to the large gear disk 7. When the large gear disk 7 rotates, the water supply iron pipe 9 will rotate together, without generating movement interference and affecting the water supply efficiency.

[0025] During operation, first fill the inside of the box body 4 with water through the water filling hopper 5, and then aim the spray tube 12 at the dust in the air. At this time, use the water pump 19 to supply the water inside the box body 4 to the water supply iron pipe 9. The water supply iron pipe 9 injects the water into the high-pressure nozzle 14 through the hose 10.
