Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to a combined cleaning device for return belts. Background Technology

[0002] Belt conveyors are widely used due to their advantages such as low operating cost, large conveying capacity, and long conveying distance, and are widely used in many fields.

[0003] When using belt conveyors to transport dry or wet materials such as ores and sand, the powder adhering to the conveyor surface is shaken off during the return trip, causing material to accumulate and clump under the belt. In severe cases, excessive material accumulation accelerates belt wear, and severe wear can lead to problems such as belt overheating and fire, and belt tearing.

[0004] Material buildup on the return conveyor belt requires regular manual cleaning, increasing the workload of staff, which is time-consuming, labor-intensive, and increases potential risks. Utility Model Content

[0005] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a return belt cleaning combination device.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A return belt cleaning assembly includes a cleaning tank, which is equipped with a water supply pipe and a sewage discharge pipe. An overflow trough is provided on the side of the cleaning tank, and the output end of the overflow trough is connected to the sewage discharge pipe. Two brush rollers are rotatably installed inside the cleaning tank, and a motor is installed on the power end of each brush roller. A tension roller is installed between the two brush rollers in the cleaning tank.

[0008] The upper side of the cleaning tank is equipped with a roller, an upper support roller, a scraper device, an electric heater, and a temperature sensing module.

[0009] Furthermore, the sewage pipe is connected to a compressed air pipe on its side. Both the compressed air pipe and the sewage pipe are equipped with pulse valves. In this design, the pulse valves function as on / off valves, and the compressed air from the compressed air pipe, when passing through the sewage pipe, combines with water to form a high-speed water-air turbulence. This pulse action of the mixed fluid can flush the inner wall of the pipe, causing attached dirt (such as sand, gravel, and rust) to peel off and be discharged with the water flow, effectively preventing the accumulation of deposits. Moreover, the high-pressure compressed air can quickly remove residual foreign objects or soft blockages in the pipe, ensuring that the sewage pipe is unobstructed. Its principle is similar to the technology used to unclog car fuel lines, using directional airflow to move blockages and also using air pressure differences to create stronger fluid dynamics, accelerating the discharge speed of sewage and solid particles.

[0010] Furthermore, a bevel gear drive shaft is installed between the two brush rollers. This design allows the two brush rollers to rotate synchronously in the same direction with only one motor.

[0011] Furthermore, a high-pressure rinsing water gun is installed on the upper side of the cleaning tank in front of the upper idler roller. This design achieves a rinsing effect and enhances the cleaning ability of the belt.

[0012] Further specifying, the scraper device includes mounting plates installed on the upper and lower sides of the belt, with guide rods slidably mounted on the mounting plates, scrapers mounted on the ends of the guide rods, and springs installed between the scrapers and the mounting plates, with the springs sleeved on the outside of the guide rods. This design ensures that the scrapers are always in contact with the belt, thereby achieving the purpose of scraping away debris from the belt.

[0013] The beneficial effects of using this utility model are as follows:

[0014] This invention features a cleaning tank. The belt is fully immersed in the water in the cleaning tank via a tensioning wheel. The tensioning wheel causes the belt to come into contact with the brush roller. The reverse rotation of the brush roller creates reverse cleaning of the belt, removing residual powder from the belt surface. At the same time, the brush rolls in the water, which can play a self-cleaning role. Large particles settle naturally and are discharged from the drain pipe below.

[0015] With the structural design of this utility model, when the belt leaves the water surface, after passing the upper roller, the water stains on the belt surface are scraped off by the scraper device. The water stains drip into the cleaning tank below, ensuring that the water does not flow out. After passing the scraper device, the belt surface is dried by two sets of multiple electric heating guns at the top and bottom, while the temperature sensing module is linked to ensure that the belt temperature does not become too high and cause other risks.

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 , Figure 2 As shown, the present invention provides a return belt cleaning assembly, including a cleaning tank 1, a water supply pipe 2 and a sewage discharge pipe 3, an overflow tank 4 on the side of the cleaning tank 1, the output end of the overflow tank 4 being connected to the sewage discharge pipe 3, two brush rollers 5 being rotatably installed inside the cleaning tank 1, a motor being installed at the power end of the brush rollers 5, and a tension roller 6 being installed between the two brush rollers 5 in the cleaning tank 1.

[0024] The upper side of the cleaning tank 1 is equipped with a roller 7, an upper support roller 8, a scraper device 9, an electric heater 10, and a temperature sensing module 11.

[0025] Preferably, a compressed air pipe 12 is connected to the side of the sewage pipe 3. Both the compressed air pipe 12 and the sewage pipe 3 are equipped with pulse valves 13. In this design, the pulse valves 13 act as open and close valves, while the compressed air from the compressed air pipe combines with water to form a high-speed water-air turbulence when passing through the sewage pipe. The pulse action of this mixed fluid can flush the inner wall of the pipe, causing attached dirt such as sand, gravel, and rust to peel off and be discharged with the water flow, effectively preventing the accumulation of deposits. Moreover, the high-pressure compressed air can quickly remove residual foreign objects or soft blockages in the pipe, ensuring that the sewage pipe is unobstructed. Its principle is similar to the technology of unclogging car oil passages, which uses directional airflow to push the blockage to move, and can also form stronger fluid dynamics through air pressure difference to accelerate the discharge speed of sewage and solid particles. In practice, a structure that is conducive to sewage discharge can also be considered according to specific circumstances.

[0026] Preferably, a bevel gear drive shaft 14 is installed between the two brush rollers 5. With this design, only one motor is needed to achieve synchronous and unidirectional rotation of the two brush rollers 5. In fact, the transmission structure can also be considered according to the specific situation.

[0027] A high-pressure rinsing water gun 15 is preferably installed on the upper side of the cleaning tank 1 in front of the upper idler roller 8. This design achieves the rinsing effect and enhances the cleaning ability of the belt. In fact, the installation position, number and installation angle of the high-pressure rinsing water gun 15 can also be considered according to the specific situation.

[0028] The preferred scraper device 9 includes mounting plates 91 installed on the upper and lower sides of the belt. A guide rod 92 is slidably mounted on the mounting plate 91. A scraper 93 is installed at the end of the guide rod 92. A spring 94 is installed between the scraper 93 and the mounting plate 91. The spring 94 is sleeved on the outside of the guide rod 92. With this design, the scraper 93 can always be in contact with the belt, thereby achieving the purpose of scraping away debris from the belt. In fact, the selection and installation method of the scraper device 9 can also be considered according to the specific situation.

[0029] In this embodiment, when using a return belt cleaning assembly, the belt enters the cleaning tank 1 under the tension roller 6 after the roller 7 has turned. Under the effect of the tension roller 6, its surface comes into contact with the brush rollers 6 on both sides of the tension roller 6. When the brush rollers 6 rotate, its surface is brushed clean. It should be noted that the brush rollers 6 can be unpowered. Because they are in contact with the belt, they can also be driven to rotate by the moving belt to achieve a certain cleaning effect. Of course, the cleaning effect is better when the brush rollers 5 do not rotate, especially when the brush rollers 5 rotate in the opposite direction to the movement of the belt.

[0030] The belt is cleaned once by the brush roller 5 and then moved out of the cleaning tank 1 by the upper support roller 8 after being soaked in water in the cleaning tank 1. During this period, a high-pressure water gun 15 can be used for secondary cleaning, preferably with a water flow rate of 50 kg / cm³ at a jet angle of 15 degrees. Then, the belt is cleaned three times by the scraper device 9, and the scraped water and impurities fall directly back into the cleaning tank 1. After that, the belt is dried by the electric hot air gun 10, preferably by blowing the belt at 45°. After drying, the temperature is detected by the temperature sensing module 11 to ensure that the belt temperature does not become too high and cause other risks.

[0031] The overflow tank 4 in the cleaning tank 1 ensures that the water level is controlled to reach the overflow port height, but not higher than the maximum overflow port height, so that the belt can enter the water.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
