[0002] In the process of calcium carbide production, after the tail gas of the calcium carbide furnace undergoes multi-stage cooling and dust removal, the collected solid dust is commonly known as purification ash. The general treatment method of the purification ash in the calcium carbide industry is to transport it out and landfill it. Since the purification ash contains tar and a relatively high content of volatile components, and at the same time the purification ash has a relatively high temperature, and it also contains a small amount of calcium carbide powder, sulfur and phosphorus, it is flammable when contacting air, posing certain safety hazards. When the truck is transporting, the purification ash is easy to burn and damage the vehicle when contacting air, causing safety accidents. At the same time, when dumping, the dust is extremely easy to disperse, seriously polluting the air. Therefore, it is necessary to humidify the purification ash before transfer.

[0003] In the prior art, most of the humidification treatment of the purification ash is carried out by spraying the surface of the purification ash with a spraying device, and at the same time, a stirring device is used to stir the inside to achieve the effect of humidifying the purification ash. Since the purification ash is piled up together, but the spraying device can only spray the surface of the purification ash, and the purification ash piled up inside can only be turned out by the stirring device and then sprayed, resulting in low spraying efficiency and affecting the humidification efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a spraying device for purifying ash cooling, which solves the problem that in the prior art, the spraying device can only spray the surface of the purification ash and cannot spray the purification ash piled up inside at the same time, resulting in low spraying efficiency and affecting the humidification efficiency.

The top end of the hollow tube rotates through the top of the humidifying bin and is communicated with a water pipe through a rotary flange. The bottom of the humidifying bin is communicated with a discharging tube, and a valve is arranged on the discharging tube.

[0007] A further technical solution is that the top of the humidifying bin is provided with a movable hole penetrating through its interior. A rotating bearing is arranged in the movable hole. The outer ring of the rotating bearing is connected with the inner wall of the movable hole, and the inner ring of the rotating bearing is connected with the outer side of the hollow tube.

[0009] A further technical solution is that an arc-shaped scraping plate horizontally arranged inside the humidifying bin is connected to the bottom end of the hollow pipe, and the arc-shaped scraping plate is movably abutted against the bottom of the humidifying bin.

[0010] A further technical solution is that a discharge pipe is communicated with one side of the bottom of the discharge cylinder, a driving motor is installed at the bottom of the discharge cylinder, the transmission shaft of the driving motor rotates through the inside of the discharge cylinder, and is drivingly connected to a driving rod vertically arranged inside the discharge cylinder.

Detailed implementation

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Embodiment 1:

[0021] Refer to Figure 1 、 Figure 2It is shown that a spray device for purifying ash cooling in the utility model comprises a humidifying bin 1. A feeding cylinder 2 is arranged at the top of the humidifying bin 1. A rotating hole 3 penetrating through its interior is opened at the bottom of the humidifying bin 1. A servo motor 4 is arranged at the bottom of the humidifying bin 1. The output shaft of the servo motor 4 penetrates into the interior of the humidifying bin 1 through the rotating hole 3. A sealing gasket 5 is arranged in the rotating hole 3. The sealing gasket 5 is provided to prevent the purified ash and spray water inside the humidifying bin 1 from overflowing through the rotating hole 3. The output shaft of the servo motor 4 is drivingly connected with a hollow tube 6 vertically arranged inside the humidifying bin 1. A plurality of branch pipes 7 communicated with the hollow tube 6 are fixedly arranged on the outer surface of the hollow tube 6. A plurality of water spraying holes 8 penetrating through their interiors are opened on the outer surface of the branch pipes 7. The top end of the hollow tube 6 rotatably penetrates through the top of the humidifying bin 1 and is communicated with a water pipe 10 through a rotating flange 9. In the actual use process, a high-pressure water pump in the prior art can be installed on the water pipe 10 to increase the water pressure in the water pipe 10. By arranging the rotating flange 9, the hollow tube 6 is communicated with the water pipe 10, which can ensure the smooth rotation of the hollow tube 6 without affecting the water pipe 10. The bottom of the humidifying bin 1 is communicated with a discharging cylinder 11. A valve 12 is arranged on the discharging cylinder 11. In the actual use process, the valve 12 on the discharging cylinder 11 is closed, and purified ash is added into the humidifying bin 1 through the feeding cylinder 2. The water pipe 10 is started to supply water to the hollow tube 6. The hollow tube 6 supplies water to the branch pipes 7 respectively to make the water spraying holes 8 spray water, so that the interior and surface of the piled-up purified ash can be directly sprayed and humidified at the same time, thereby improving the humidifying efficiency of the purified ash. At the same time, the servo motor 4 is started to work. The output shaft of the servo motor 4 drives the hollow tube 6 to rotate, and then drives the branch pipes 7 to rotate. The branch pipes 7 spray water on the piled-up purified ash circularly for humidification, and can also play a role in stirring the purified ash, so that the purified ash is uniformly humidified to ensure the humidifying effect. When the humidification is completed, the water supply of the water pipe 10 is stopped. Under the action of the output shaft of the servo motor 4 driving the hollow tube 6 to rotate and then driving the branch pipes 7 to rotate to stir the purified ash, the valve 12 of the discharging cylinder 11 is opened, and the purified ash is discharged through the discharging cylinder 11. After the purified ash is discharged completely, if the interior of the humidifying bin 1 needs to be cleaned, the water pipe 10 is opened again to supply water to the hollow tube 6. The hollow tube 6 supplies water to the branch pipes 7 respectively to make the water spraying holes 8 spray water into the interior of the humidifying bin 1 for flushing. Since the branch pipes 7 rotate under the action of the servo motor 4 and the hollow tube 6, the purified ash is not easily adhered to the water spraying holes 8. At the same time, the water pressure provided by the water pipe 10 is large, so that the water flow pressure sprayed from the water spraying holes 8 is relatively large, and the purified ash adhered to the water spraying holes 8 can be washed away, thereby ensuring that the purified ash does not block the water spraying holes 8.

[0022] An activity hole 13 penetrating through its interior is opened at the top of the humidifying bin 1. A rotating bearing 14 is arranged in the activity hole 13. The outer ring of the rotating bearing 14 is connected with the inner wall of the activity hole 13, and the inner ring of the rotating bearing 14 is connected with the outer side of the hollow tube 6. By arranging the rotating bearing 14, the stability of the hollow tube 6 driving the branch pipes 7 to rotate is ensured.

[0023] Example 2:

[0024] Based on the foregoing Example 1, refer to Figure 1 It is shown that at one end of the branch pipe 7 far from the hollow pipe 6, a scraping rod 15 is fixedly connected. The scraping rods 15 are all movably abutted against the inner wall of the humidifying bin 1. By providing the scraping rods 15, when the branch pipe 7 rotates, the scraping rods 15 are driven to rotate. The scraping rods 15 are movably abutted against the inner wall of the humidifying bin 1, so that the purification ash adhered to the inner wall of the humidifying bin 1 can be cleaned, avoiding the solidification of the purification ash adhered to the inner wall and affecting the subsequent use of the device.

[0025] Example 3:

[0026] Based on the foregoing Example 1, refer to Figure 1 , Figure 3 It is shown that at the bottom end of the hollow pipe 6, an arc-shaped scraping plate 16 horizontally arranged inside the humidifying bin 1 is connected. The arc-shaped scraping plate 16 is movably abutted against the bottom of the humidifying bin 1. During actual use, by providing the arc-shaped scraping plate 16, the servo motor 4 drives the hollow pipe 6 to rotate, and then drives the arc-shaped scraping plate 16 to rotate. The arc-shaped scraping plate 16 can clean the purification ash adhered to the bottom side inside the humidifying bin 1, and at the same time, when discharging materials through the discharge cylinder 11 after humidification, the arc-shaped scraping bar is also convenient for scraping the purification ash inside the humidifying bin 1 into the discharge cylinder 11 for discharge.

[0027] Example 4:

[0028] Based on the foregoing Example 1, refer to Figure 1 , Figure 3 It is shown that on one side of the bottom of the discharge cylinder 11, a discharge pipe 17 is communicated. A driving motor 18 is installed at the bottom of the discharge cylinder 11. The transmission shaft of the driving motor 18 rotates through the inside of the discharge cylinder 11, and is drivingly connected to a driving rod 19 vertically arranged inside the discharge cylinder 11. A spiral auger 20 is sleeved outside the driving rod 19. The blades of the spiral auger 20 are movably abutted against the inner wall of the discharge cylinder 11. During actual use, by providing the driving motor 18 at the bottom of the discharge cylinder 11 and the spiral auger 20 inside the discharge cylinder 11, the driving motor 18 drives the spiral auger 20 to rotate at a constant speed through the driving rod 19. The purification ash in the humidifying bin 1 enters the discharge cylinder 11 and is conveyed under the uniform pushing of the blades of the spiral auger 20, and then discharged through the discharge pipe 17, ensuring uniform discharging, and at the same time preventing the purification ash from being blocked in the discharge cylinder 11 and affecting subsequent discharging.

[0029] Example 5:

[0030] Refer to Figure 4It is shown that an observation port communicating with the inside of the humidification chamber 1 is provided on the outer side of the humidification chamber 1, and an explosion-proof glass 22 is installed in the observation port. By providing the observation port and the explosion-proof glass 22, the spraying condition inside the humidification chamber 1 can be directly observed, which is convenient for performing corresponding operations according to the condition inside the humidification chamber 1.
