Technical Field

[0001] This utility model relates to the field of spray fan technology, and in particular to a spray fan that facilitates pipeline disassembly. Background Technology

[0002] A large amount of dust is generated during mining, stone processing, and stone crushing operations. This dust disperses in the air, causing air pollution, posing a safety threat to the environment and workers, and affecting their health. To reduce dust dispersion, spray fans are needed to make the dust settle.

[0003] In the current use of spray fans, water needs to be supplied through pipelines to the equipment to complete the dust suppression spraying work. Since most existing water supply pipelines are fixed with flanges or bolt clamps, disassembly requires wrenches and screwdrivers. When workers do not have wrenches and screwdrivers, disassembly becomes impossible, affecting pipeline replacement. Therefore, a spray fan with convenient pipeline disassembly is proposed to solve the above problems. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a spray fan with convenient pipeline disassembly, including a base 1, a fixing frame 2 fixedly connected to the top of the base 1, a spray fan 3 mounted inside the fixing frame 2, a mounting plate 7 fixedly connected to the surface of the spray fan 3, a protective shell 4 rotatably connected to the surface of the mounting plate 7, a groove 10 formed on the surface of the protective shell 4, a water supply pipe 6 made of rubber installed inside the protective shell 4, a toothed ring 15 fixedly connected to the inner wall of the protective shell 4, a threaded rod 13 rotatably connected to the inside of the mounting plate 7, the end of the threaded rod 13 away from the mounting plate 7 contacting the inner wall of the protective shell 4, a gear 14 fixedly connected to the surface of the threaded rod 13, the gear 14 contacting the surface of the mounting plate 7, the surface of the gear 14 meshing with the surface of the toothed ring 15, a connecting rod 12 threadedly connected to the surface of the threaded rod 13, the end of the connecting rod 12 away from the threaded rod 13 fixedly connected to a sliding shell 9, the sliding of the sliding shell 9 being guided and controlled by the connecting rod 12.

[0025] A water supply pipe 17 is fixedly connected to the surface of the mounting plate 7. The water supply pipe 17 is tapered, which makes it easier for the water supply pipe 6 to cover the surface of the water supply pipe 17 when it is inserted. The water supply pipe 17 is connected to the pipe inside the spray fan 3. Water is supplied to the inside of the spray fan 3 through the water supply pipe 17, and the spray fan 3 sprays water out as a water mist to reduce dust on the mine. This is existing known technology, so it will not be explained further.

[0026] The protective shell 4 is fixedly connected to a series of circumferentially arranged fixing rods 5. The fixing rods 5 make it easier for the protective shell 4 to be rotated.

[0027] The sliding shell 9 is fixedly connected to a pressing tube 11, and the pressing tube 11 has an arc-shaped ring inside.

[0028] The mounting plate 7 is fixedly connected to the surface of the fixing shell 8, and the interior of the fixing shell 8 is slidably connected to the surface of the sliding shell 9. The sliding shell 9 covers the water supply pipe 17, thereby preventing the remaining water inside the water supply pipe 6 from flowing out and contacting the gear 14 and the gear ring 15 when the water supply pipe 6 is disassembled, thus protecting the gear 14 and the gear ring 15.

[0029] A rubber pad is fixedly connected to the surface of the sliding shell 9. The surface of the rubber pad is in contact with the fixed shell 8. The rubber pad fills the gap between the fixed shell 8 and the sliding shell 9, further preventing water leakage.

[0030] The mounting plate 7 has a drain pipe 16 inside, which extends to the outside of the mounting plate 7. The drain pipe 16 is designed to drain the dripping water and prevent water from remaining inside the fixed shell 8.

[0031] Working principle: When the water supply pipe 6 needs to be installed, it is pushed into the protective shell 4 through the groove 10. Then, the water supply pipe 6 passes through the pressing tube 11 and contacts the water delivery pipe 17. Due to the tapered shape of the water delivery pipe 17, the water supply pipe 6 is pushed onto the surface of the water delivery pipe 17. Then, the operator moves the fixing rod 5, which in turn rotates the protective shell 4. The protective shell 4 then rotates the gear ring 15, which drives the gear 14 to rotate. The gear 14 then drives the threaded rod 13 to rotate, which in turn drives the connecting rod 12. Because of the sliding shell 9, the connecting rod 12 does not rotate with the threaded rod 13, but moves with the rotation of the threaded rod 13. This causes the connecting rod 12 to move the sliding shell 9 downwards. The sliding shell 9 drives the pressing tube 11 to move downwards and press the surface of the water supply pipe 6. Due to the rubber properties of the water supply pipe 6, the surface of the water supply pipe 6 and the water delivery pipe 17 are tightly attached, thus completing the installation of the water supply pipe 6. When the water supply pipe 6 is disassembled, the fixing rod 5 is rotated. The fixing rod 5 drives the protective shell 4, the toothed ring 15, the gear 14, and the threaded rod 13 to rotate, which in turn drives the connecting rod 12. The connecting rod 12 drives the sliding shell 9 and the pressing tube 11 to move upwards. The pressing tube 11 no longer presses the water supply pipe 6, and then the water supply pipe 6 is pulled, completing the separation of the water supply pipe 6 and the water delivery pipe 17. At the same time, during disassembly, the water supply to the equipment is stopped first, and the water inside the water supply pipe 6 is drained, thus avoiding excessive water retention inside the water supply pipe 6.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
