Description

Technical Field

[0001] This utility model relates to the field of ore processing technology, and more specifically, to a cleaning structure for a belt conveyor line for ore processing. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain usable properties. It can be divided into metallic minerals and non-metallic minerals. In the process of ore processing, conveyor belts are needed to transport the ore.

[0003] A search revealed that utility model patent CN220702225U discloses a belt cleaning device for conveying ore. The device includes a belt conveyor with a brush cleaning device located below the discharge end. A rotating roller on the brush cleaning device is connected to a drive shaft on the belt conveyor via a pulley. The brush cleaning device utilizes the drive shaft's rotation during material transport to perform reverse cleaning of the belt conveyor's belt using brushes. This device cleans residual material from the ore conveyor belt, preventing damage to the conveyor, eliminating safety hazards for workers cleaning the belt conveyor, reducing manual labor, and minimizing electricity consumption and production costs.

[0004] However, the aforementioned patents have the following shortcomings: they are not convenient for collecting the swept-off ore dust, and dust is easily generated during sweeping; when wet ore adheres to the conveyor belt, the drying speed of the wet ore by the hot air blown out of the air outlet is slow, making it difficult to completely remove it with a brush later, thus affecting the cleaning effect. Therefore, we propose a cleaning structure for a belt conveyor line used in ore processing. Utility Model Content

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, when the conveyed ore is in a dry state, the first electric push rod drives the dust collection box and the first brush roller to move upward so that the top of the first brush roller contacts the bottom surface of the conveyor belt. The first motor drives the first brush roller to rotate and sweep off the dust attached to the conveyor belt. At the same time, the vacuum pump generates suction force to make the dust collection hood generate suction force. The suction force of the dust collection hood sucks the dust swept off by the first brush roller into the inner cavity of the dust collection box. The filter cotton is used to intercept the dust that enters the inner cavity of the dust collection box, so as to collect the dust of the ore and clean the dust attached to the conveyor belt.

The second electric push rod drives the water tank, the second brush roller and the scraper to move up, so that the top surface of the scraper and the top of the second brush roller respectively contact the bottom surface of the conveyor belt. The water in the water tank cavity is pumped into the spray pipe by the water pump, and the water is sprayed from the spray hole onto the conveyor belt to wash it. In addition, the second motor drives the second brush roller to rotate to sweep the wet ore adhering to the conveyor belt, thus realizing the function of cleaning the wet ore adhering to the conveyor belt. The top of the scraper scrapes the cleaned conveyor belt to clean the residual water stains on the conveyor belt. The cleaned ore and water are separated by the filter screen inside the pull box, so that the cleaning water falls to the bottom of the water tank cavity for recycling, thus realizing the function of effectively cleaning the wet ore adhering to the conveyor belt.

[0031] For details, please refer to Figure 1 The end of the conveyor frame 1 is provided with a material guide plate 29, and a control panel 30 is fixedly installed on the outside of the conveyor frame 1.

[0032] In this embodiment, the ore conveyed on the conveyor belt 3 is guided by the material guide plate 29, so that the ore falls off the material guide plate 29. In addition, the device is controlled by the control panel 30.

[0033] For details, please refer to Figure 1 and Figure 4 The inner wall of the pull-out groove 16 fits against the side of the pull-out box 17.

[0034] In this embodiment, the stability of the pull-out box 17 being fitted into the inner cavity of the pull-out slot 16 is ensured so that the filter screen 18 inside the pull-out box 17 can catch the cleaning water returning from the water receiving cover 19, while the pull-out box 17 is used to filter the minerals in the cleaning water.

[0035] For details, please refer to Figure 3 The dust collection box 7 has a sealing door 28 hinged at the front.

[0036] In this embodiment, the dust collected in the dust collection box 7 is cleaned by opening the sealed door 28.

[0037] For details, please refer to Figure 4 A drain valve 27 is fixedly installed at the front of the water tank 15, and the end of the drain valve 27 extends to the bottom of the inner cavity of the water tank 15.

[0038] In this embodiment, the cleaning wastewater at the bottom of the inner cavity of the water tank 15 is discharged through the drain valve 27 so as to replace the cleaning water.

[0039] Working principle: In operation, the conveyor belt 3 first transports the ore, causing it to slide off the material guide plate 29 into the processing equipment at the end of the conveyor belt 3. When the ore is dry, some ore powder will adhere to the conveyor belt 3. At this time, the first electric push rod 6 is activated to move the dust collection box 7, the dust suction hood 8, and the first brush roller 11 upwards, so that the top of the first brush roller 11 contacts the bottom surface of the conveyor belt 3. The first motor 12 is then activated to drive the first brush roller 11 to rotate counterclockwise, thereby removing the dust adhering to the conveyor belt 3. As dust is swept away, the vacuum pump 10 is activated to draw air from the inner cavity of the dust collection box 7, creating a negative pressure inside the dust collection box 7. This negative pressure then generates suction from the suction hood 8, drawing the dust swept away by the first brush roller 11 into the inner cavity of the dust collection box 7. The filter cotton 9 traps the dust entering the inner cavity of the dust collection box 7, thus collecting ore dust and cleaning dust adhering to the conveyor belt 3. Finally, when the conveyed ore is damp, the dust on the conveyor belt 3 will... When wet base ore adheres, the second electric push rod 14 is activated, causing the water tank 15, water receiving cover 19, second brush roller 20, and scraper 26 to move upwards. This brings the top surface of the scraper 26 and the top of the second brush roller 20 into contact with the bottom surface of the conveyor belt 3. Simultaneously, the water pump 22 is activated, drawing water from the inner cavity of the water tank 15 through the water guide steel pipe 23 to the inner cavity of the spray pipe 24. The water in the spray pipe 24 is then sprayed from the spray holes 25 onto the conveyor belt 3, thus rinsing the conveyor belt 3. At the same time, the second motor 21 is activated, causing the second brush roller 20 to rotate counterclockwise. The conveyor belt 3 rotates, and the rinsing water cleans the wet base ore adhering to it. The cleaned ore and water fall back into the inner cavity of the water tank 15. The filter screen 18 inside the pull-out box 17 separates the ore and the rinsing water, so that the rinsing water falls to the bottom of the inner cavity of the water tank 15 for recycling. The pull-out box 17 and the filter screen 18 collect the ore that has been rinsed. In addition, as the conveyor belt 3 rotates, the rinsed part on the conveyor belt 3 is scraped by the top of the scraper 26, thereby cleaning off the remaining water stains.
