Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaning, in particular to a cleaning mechanism for an ore conveyor belt. Background Art

[0002] Mining is the technology and science of extracting mineral resources from within the earth's crust and on the earth's surface. The mining industry is an important raw material industry. Among them, iron ore is an important raw material for the smelting industry. During the process of iron ore mining, the mined iron ore needs to be transported through a conveyor belt. Since the surface of the ore will adhere to soil or ore slag during the mining process, these soils and slag are easily adhered to the surface of the conveyor belt during the transfer process through the conveyor belt. Long-term transportation is likely to cause the adhered soil and slag to form lumps on the surface of the conveyor belt. The lumps condensed on the conveyor belt not only occupy the conveying space of the conveyor belt, reducing the conveying efficiency, but also make the conveyor belt heavier and heavier, increasing the motor load and possibly causing motor damage, resulting in poor use effect.

[0003] In the prior art, most of the cleaning of the ore conveyor belt is to set a rubber scraper under the conveyor belt. Through the contact between the surface of the conveyor belt and the scraper, the surface of the conveyor belt is scraped and cleaned, so as to achieve the cleaning effect of the conveyor belt surface. However, in actual use, due to the uneven adhesion of soil or slag on the surface of the conveyor belt, the scraper cannot effectively scrape off the adhered soil and slag. As more and more lumps are formed on the surface of the conveyor belt by soil or ore slag, it is easy to cause the conveyor belt to slip. At the same time, the increase of scraping by the scraper is likely to cause damage to the scraper. Therefore, there is room for improvement. Summary of the Utility Model

[0004] The utility model provides a cleaning mechanism for an ore conveyor belt to solve the problems raised in the background art.

[0005] In order to solve the above problems, the present invention provides an ore conveyor belt cleaning mechanism, including a cleaning mechanism arranged under the conveyor belt, the cleaning mechanism is composed of a water tank, a cleaning roller, a scraper, and a flushing pipe.

[0011] The beneficial effects of adopting the above technical solution are:

[0012] 1. Through the friction wheel on the cleaning roller and the surface of the conveyor belt, the driving of the conveyor belt drives the cleaning roller to rotate, and the surface of the conveyor belt is cleaned by the brush, and the powder adhering to the surface of the conveyor belt is swept off and dropped into the L-shaped sewage box. As the cleaning roller rotates, the powder in the L-shaped sewage box is discharged from the sewage guide port by the brush bristles, and is collected and processed centrally by external equipment to prevent the powder from falling and affecting the operation of the first guide rod and the first spring.

[0013] 2. The adhesion on the surface of the conveyor belt that has not been cleaned can be scraped off through the setting of the scraper.

[0014] 3. Through the cooperation of the first guide rod and the first spring, the bristles on the cleaning roller in the L-shaped sewage box and the scraper always contact the surface of the conveyor belt, ensuring the stability of the cleaning and scraping work.

[0024] As Figures 1-3 , in this embodiment, an ore conveyor belt cleaning mechanism includes a cleaning mechanism 2 provided below the conveyor belt 1. The cleaning mechanism 2 is composed of a water tank 21, a cleaning roller 22, a scraper 23, and a flushing pipe 24. The top of the water tank 21 is open, and a support frame 25 is installed on the right side. A sewage discharge port 211 is opened in the upper left part. An inclined filter screen 212 is provided in the water tank 21. An L-shaped sewage discharge box 26 is movably installed on the upper part of the support frame 25. A group of first guide rods 251 are slidably penetrated through both ends of the support frame 25, and each group of first guide rods 251 has two. A limit ring is provided at the bottom end of the first guide rod 251, and the top end is connected to the top of the L-shaped sewage discharge box 26. A first spring 253 is sleeved in the first guide rod 252, and the first spring 253 is located between the L-shaped sewage discharge box 26 and the support frame 25. The cleaning roller 22 is rotatably installed in the upper opening of the L-shaped sewage discharge box 26, and bristles in contact with the surface of the conveyor belt 1 are provided on the surface of the cleaning roller 22. An installation frame 261 is installed at the left top end of the L-shaped sewage discharge box 26. The scraper 23 is made of rubber and is installed on the top of the installation frame 261 by bolts and is in contact with the surface of the conveyor belt 1. The flushing pipe 24 is installed in the side surface of the L-shaped sewage discharge box 26 near the water tank 21, and the flushing pipe 26 is communicated with a water pump. The water pump is provided in the water tank 21 and is located below the filter screen 212.

[0025] Through the above technical solution, when in use, the operation of the conveyor belt 1 drives the cleaning roller 22 to rotate, and the bristles in the cleaning roller 22 clean the surface of the conveyor belt 1 to sweep away the powdery adhesions, and then the scraper 23 is used to scrape off the adhesions that have not been swept away on the surface of the conveyor belt 1. The swept and scraped adhesions fall into the L-shaped discharge box 26. The cooperation of the support frame 25, the first guide rod 251, and the first spring 252 makes the L-shaped discharge box 26 elastic, thereby ensuring that the bristles on the cleaning roller 22 and the scraper 23 are in contact with the conveyor belt 1. The conveyor belt surface 1 is in conflict with the conveyor belt surface 1 to ensure the stability of cleaning and scraping. The surface of the conveyor belt 1 is then flushed through the flushing pipe 24 to flush out the agglomerated adhering debris that has not been swept off and scraped. With high-pressure flushing, the adhering debris falls into the filter screen 212 at the upper part of the water tank 21. The filter screen 212 separates the solid debris and water. The water enters the water tank 21 for recycling. The solid debris moves along the surface of the inclined filter screen 212 with the water flow to the sewage outlet 211. The solid impurities are collected and processed by external equipment. The three steps of cleaning, scraping, and flushing can ensure the cleanliness of the conveyor belt 1 after cleaning, improve the cleaning effect, and avoid damage to the scraper.

[0026] Preferably, friction wheels 221 are provided at both ends of the cleaning roller 22 for contacting the surface of the conveyor belt 1 .

[0027] Through the above technical solution, the arrangement of the friction wheel 221 enables the cleaning roller 22 to stably rotate under the drive of the conveyor belt 1 to complete the cleaning work.

[0028] Preferably, a downwardly inclined sewage outlet 262 is provided on the right side of the L-shaped sewage box 26 .

[0029] Through the above technical solution, the setting of the L-shaped sewage box 26 can prevent the swept and scraped adhered debris from falling directly, affecting the operation of the first guide rod 251 and the first spring 252. Through the setting of the sewage outlet 262, the swept and scraped debris can be discharged from the sewage outlet 261 through the bristles as the cleaning roller 22 rotates, making it convenient for centralized processing through external collection equipment.

[0030] Preferably, the lower end of the filter screen 212 is located at the sewage outlet 211 and is located at the same horizontal plane as the sewage outlet 211 .

[0031] Through the above technical solution, it is ensured that the separated solid impurities can move along the upper surface of the filter screen 211 to the sewage outlet 211 for discharge.

[0032] Preferably, a plurality of high-pressure nozzles 241 are evenly spaced in the flushing pipe 24 , and the high-pressure nozzles 241 are inclined toward the outer surface of the conveyor belt 21 .

[0033] Through the above technical solution, the high-pressure nozzle 241 improves the flushing ability of the surface of the conveyor belt 1, facilitating the flushing off of the caked debris adhering to the surface of the conveyor belt 1.

[0034] Preferably, above the sewage outlet 211 of the water tank 21, an inverted U-shaped support frame 271 is installed, and two symmetric second guide rods 272 are symmetrically and slidably penetrated through the inverted U-shaped support frame 271. A limiting ring is provided at the bottom of the second guide rod 272, and a rubber wiper 27 is installed at the top. A second spring 273 is sleeved in the second guide rod 272, and the second spring 273 is located between the wiper 27 and the inverted U-shaped support frame 271. The wiper 27 abuts against the surface of the conveyor belt 1.

[0035] Through the above technical solution, the setting of the wiper 27 can scrape off the debris and water adhering to the surface of the conveyor belt 1 after flushing, ensuring the cleanliness and dryness of the surface of the conveyor belt 1. Through the cooperation of the inverted U-shaped support frame 271, the second guide rod 272, and the second spring 273, the wiper 27 has elasticity, ensuring the stability of its contact with the surface of the conveyor belt 1 and the stability of the scraping operation.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than limiting the technical solutions described in the present invention. Therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced.
