Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically to a spraying device for a sintered ore conveyor belt. Background Technology

[0002] Sintering is a crucial step in steel production. Sintered clinker is transported to the blast furnace via conveyor belt. During transportation, the sinter may not be cooled properly. High-temperature sinter can easily ignite the conveyor belt during transport, causing the entire conveying system to burn down and resulting in heavy losses.

[0003] Utility model patent CN220418086U discloses an automatic water supply system for a conveyor belt. Sintered ore is cooled by a ring cooler and then discharged into a feeder. A heat source sensor on the feeder monitors the temperature of the cooled sintered ore. When the temperature exceeds 120°C, the heat source sensor sends a spray signal to a spray device on the conveyor to spray the sintered ore, preventing it from overheating and damaging the conveyor or causing combustion. The water supply system has an electrically adjustable valve connected to the water pipe. This valve is connected to the heat source sensor, which controls the opening and closing of the valve. However, if the electric valve malfunctions, the water supply system is ineffective and cannot effectively cool the high-temperature sintered ore. Therefore, a spray device for sintered ore conveyor belts that allows for manual / automatic switching of water supply control is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying device for sinter conveyor belts to solve the problem of electric valve failure in emergency situations, which prevents the spraying and cooling of sinter.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A spraying device for a sinter conveyor belt includes an arch frame located outside the conveyor belt and a water tank located on one side of the conveyor belt. The bottom of the water tank has a water outlet, which is connected to a water outlet box. The water outlet box is fixed to the bottom of the water tank. The lower part of the water outlet box is connected to the arch frame through a soft water pipe. A first screw is provided inside the water outlet box. One end of the first screw passes through the side wall of the water outlet box and is connected to a handwheel. The other end is provided with a screw slider. A sealing cylinder is fixedly connected to the screw slider. A return spring is provided inside the sealing cylinder. A limit ball is provided at the top of the return spring. The water outlet is blocked by the limit ball and the sealing cylinder.

[0007] In the above-mentioned sinter conveyor belt spraying device, the first screw is provided with symmetrical positioning protrusions at one end near the handwheel, the handwheel is provided with a quick connector, the quick connector is plugged into and plugged into the first screw, and a corresponding positioning groove is provided on it, the positioning groove cooperating with the positioning protrusion.

[0008] The above-mentioned sinter conveyor belt spraying device is further provided with a second screw in the water outlet tank. The second screw has the same structure as the first screw. The upper ends of the two screw sliders are fixedly connected to connecting blocks. The sealing cylinder is located on the connecting blocks. The other ends of the first screw and the second screw pass through the side wall of the water outlet tank and are respectively provided with synchronous pulleys. The two synchronous pulleys are covered with synchronous belts.

[0009] In the above-mentioned sinter conveyor belt spraying device, the second screw is connected to another quick connector at one end outside the water tank, and the other end of the quick connector is connected to the output end of the drive motor. The drive motor has a motor base at the bottom, and the motor base is fixed to the motor bracket by bolts and nuts.

[0010] The above-mentioned sinter conveyor belt spraying device has a water channel on the inner side of the upper end of the arch frame. One end of the water channel is connected to a soft water pipe, and the other end is provided with a transfer groove. A transfer pipe is provided in the transfer groove. The transfer pipe extends outward through the bottom wall of the arch frame. Its bottom is a closed end, and its side wall is connected to the spray pipe. Spray nozzles are evenly distributed at the lower end of the spray pipe, and both sides are fixed to the lower end of the arch frame by pipe supports.

[0011] The aforementioned sinter conveyor belt spraying device has a temperature sensor installed at the lower end of the arch frame.

[0012] In the above-mentioned sinter conveyor belt spraying device, a rotating shaft is rotatably connected inside the transfer pipe. One end of the rotating shaft has multiple fan blades distributed circumferentially, and the other end passes through the bottom of the transfer pipe and is fixedly connected to a cotton strip fixing block. Cleaning cotton strips are evenly distributed on the cotton strip fixing block, and the upper end of the cleaning cotton strips is in contact with a temperature sensor.

[0013] In the above-mentioned sinter conveyor belt spraying device, the liquid level at the bottom of the water tank is always higher than the arch frame, and spraying is achieved through the difference in liquid level on both sides. A viewing window is provided on one side of the water tank.

[0014] The beneficial effects of adopting the above technical solution are as follows:

[0015] This invention monitors the temperature of sintered ore on a conveyor belt using a temperature sensor. A drive motor rotates a second screw, causing the screw slider to move the sealing cylinder and limit ball horizontally, thus opening the water outlet for spraying overheated sintered ore. When the temperature sensor detects a temperature higher than the set value, but the drive motor has not started, the bolt can be loosened, and the connection between the drive motor and the second bolt can be quickly disconnected using a quick-connect fitting. The handwheel can then be turned to open the water outlet, enabling timely spraying and cooling to reduce the risk of fire. Simultaneously, a water channel is installed inside the arch frame, and a rotating shaft is installed in the water channel and the transfer pipe. The water flow drives the fan blades on the rotating shaft, causing the cotton strip fixing block and cleaning cotton strip to rotate around the rotating shaft. During this rotation, the temperature sensor is cleaned, preventing splashed slag from obscuring the sensor and affecting the accuracy of the detection results. Attached Figure Description

[0024] like Figure 1-6 As shown, this utility model includes an arch frame 2 located outside the conveyor belt 1 and a water tank 3 located on one side of the conveyor belt 1. The bottom of the water tank 3 is provided with a water outlet, which is connected to a water outlet tank 4. The water outlet tank 4 is fixed to the bottom of the water tank 3. The lower part of the water outlet tank 4 is connected to the arch frame 2 through a soft water pipe 5. A first screw 41 is provided inside the water outlet tank 4. One end of the first screw 41 passes through the side wall of the water outlet tank 4 and is connected to a handwheel 42. The other end is provided with a screw slider 411. A sealing device is fixedly connected to the screw slider 411. The sealing cylinder 43 is equipped with a return spring 431 inside. The top of the return spring 431 is equipped with a limiting ball 432. The outlet of the water outlet is blocked by the limiting ball 432 and the sealing cylinder 43. When water needs to be discharged, simply turn the handwheel 42. The screw slider 411 will drive the sealing cylinder 43 and the limiting ball 432 to move horizontally along the first screw 41. The limiting ball 432 will slide out of the water outlet. The water in the water tank 3 can flow into the water outlet box 4 through the water outlet and then flow into the arch frame 2 along the soft water pipe 5 to spray and cool the sintered ore.

[0025] like Figure 2 , 3 As shown, the first screw 41 has symmetrical positioning protrusions 412 at one end near the handwheel 42. The handwheel 42 is provided with a quick connector 44, which is plugged into and plugged into the first screw 41. A positioning groove 441 is provided on the quick connector 44. The positioning protrusions 412 are engaged in the positioning groove 441, which can limit the handwheel 42. The first screw 41 is rotated by the handwheel 42.

[0026] The water outlet tank 4 of this utility model is also provided with a second screw 45. The second screw 45 has the same structure as the first screw 41. The upper ends of the two screw sliders 411 are fixedly connected to a connecting block. The sealing cylinder 43 is located on the connecting block. The other ends of the first screw 41 and the second screw 45 pass through the side wall of the water outlet tank 4 and are respectively provided with synchronous pulleys 46. The two synchronous pulleys 46 are covered with synchronous belts 47.

[0027] like Figure 3As shown, the second screw 45 is connected at one end outside the water outlet tank 4 to another quick connector 44. The other end of the quick connector 44 is connected to the output end of the drive motor 48. The drive motor 48 has a motor base 481 at its bottom. The motor base 481 is fixed to the motor bracket 49 by bolts and nuts. Under normal circumstances, the drive motor 48 can drive the sealing cylinder 43 and the limit ball 432 to move, thereby controlling whether water is discharged. When the drive motor 48 fails and the sintered ore needs to be sprayed for cooling, the bolts and nuts can be loosened, the drive motor 48 can be removed, and the spray device can be opened using the handwheel 42 to perform emergency cooling to avoid fire accidents.

[0028] like Figure 5 , 6 As shown, a water channel 21 is provided on the inner side of the upper end of the arch frame 2. One end of the water channel 21 is connected to the soft water pipe 5, and the other end is provided with a transition groove. A transition pipe 22 is provided in the transition groove. The transition pipe 22 extends outward through the bottom wall of the arch frame 2. Its bottom is a closed end, and its side wall is connected to the spray pipe 6. Spray nozzles 61 are evenly distributed at the lower end of the spray pipe 6, and both sides are fixed to the lower end of the arch frame 2 by pipe supports 62.

[0029] The lower end of the arch frame 2 of this utility model is provided with a temperature sensor 7.

[0030] like Figure 6 As shown, a rotating shaft 23 is rotatably connected inside the adapter pipe 22. One end of the rotating shaft 23 has multiple fan blades 231 distributed circumferentially, and the other end passes through the bottom of the adapter pipe 22 and is fixedly connected to a cotton strip fixing block 24. Cleaning cotton strips 241 are evenly distributed on the cotton strip fixing block 24. The upper end of the cleaning cotton strip 241 is in contact with the temperature sensor 7. The bottom surface of the water channel 21 is an inclined surface. When the water in the water channel 21 flows to the adapter pipe 22, it pushes the fan blades 231 and drives the rotating shaft 23 to rotate. The rotating shaft 23 then drives the cotton strip fixing block 24 and the cleaning cotton strips 241 to rotate. During the rotation, the cleaning cotton strips 241 clean the bottom and the surrounding wall of the temperature sensor 7, which can prevent the slag splashed up during spraying from obstructing the temperature sensor 7.

[0031] like Figure 1 As shown, the liquid level at the bottom of the water tank 3 is always higher than that of the arch frame 2, and spraying is achieved through the difference in liquid level on both sides. A viewing window 31 is provided on one side of the water tank 3, which can be used to observe the amount of water stored in the water tank 3. A water inlet pipe 32 is provided on the water tank 3.

[0032] Work process:

[0033] 1. The temperature sensor 7 monitors the temperature of the sintered ore on the conveyor belt 1 in real time and transmits it to the monitoring center. When the temperature is higher than the set value, the drive motor 48 is turned on and drives the second screw 45 to rotate. The second screw 45 drives the first screw 41 to rotate synchronously through the synchronous pulley 46 and the synchronous belt 47. The screw sliders located on the first screw 41 and the second screw 45 drive the sealing cylinder 43 to move horizontally, so that the sealing cylinder 43 and the limiting ball 432 slide away from the water outlet hole. Water flows from the water tank 3 into the water outlet tank 4 and flows along the soft water pipe 5 into the water channel 21 of the arch frame 2.

[0034] 2. The water in the water tank 21 flows to the transfer pipe 22, thereby driving the fan blade 231 and rotating the rotating shaft 23. The rotating shaft 23 then drives the cotton strip fixing block 24 and the cleaning cotton strip 241 to rotate. During the rotation, the cleaning cotton strip 241 cleans the bottom and surrounding wall of the temperature sensor 7, which can prevent the slag splashed up during spraying from obstructing the temperature sensor 7. Since the bottom surface of the water tank 21 is inclined, when the water tank 3 stops discharging water, the water in the water tank 21 will flow to the transfer pipe, which makes it easier for the water tank 3 to discharge water again and drive the fan blade 231 to rotate.

[0035] 3. When the temperature sensor 7 detects that the temperature is higher than the set value, but the drive motor 48 has not started, the staff can remove the drive motor 48 and drive the first screw 41 to rotate through the handwheel 42, thereby opening the water outlet of the water tank 3 to cool down the overheated sinter in time.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this invention.
