Description

Technical Field

[0001] The utility model relates to the technical field of ore accumulation cleaning, in particular to a combined belt conveyor corridor cleaning ore accumulation structure. Background Art

[0002] Belt conveyors are essential equipment for transporting materials in mineral processing workshops. They play a key role in connecting various equipment and processes. They are mainly used to transport ores of different particle sizes. During transportation, the ore will generate a lot of dust and sand and stick to the belt, or accumulate around and at the bottom of the belt, causing the belt to be unable to operate, affecting production. The conventional solution is "dust removal system + manual cleaning", that is, in places where more dust is generated at the head and tail of the belt conveyor, the negative pressure generated by the dust removal system is used to collect the dust, and then discharge it from the tailings; the dust accumulated near the beltway is manually cleaned. However, the slope of the beltway is large, and employees need to climb up and down stairs to clean it. The safety risk is high because it is close to the equipment, and dust pollution can also cause harm to the employees' bodies. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that the belt conveyor operation area needs to be cleaned manually in the prior art, and personal safety and health are easily violated, the following technical solution is given, please refer to Figure 1-5 ;

[0022] A combined belt conveyor corridor cleaning ore accumulation structure comprises a belt conveyor 1, which is divided into a head section 11, a flat slope section 12 and a corridor section 13. A reciprocating scraping device 2 is provided at the head section 11, a two-pass scraping device 3 is provided at the bottom of the flat slope section 12, and a flushing nozzle 4 for cleaning residual ore accumulation and dust is provided at the bottom of the corridor section 13.

[0023] Specifically, the belt on the belt conveyor 1 passes through the reciprocating scraping device 2 and the second scraping device 3 in sequence to scrape off the mud, sand and dust on the belt, and the flushing nozzle 4 flushes the dust under the corridor section 13.

[0024] The reciprocating scraping device 2 includes a reciprocating scraper 21, a translation rod 22, a transmission frame 23, a limit frame 24, a limit frame 25, a motor 26, a rocker 27 and a transmission rod 28. The scraper edge of the reciprocating scraper 21 abuts against the belt of the head section 11. A translation rod 22 is fixed to the bottom of the reciprocating scraper 21. A transmission frame 23 is fixed to each of the two ends of the translation rod 22. Both ends of the translation rod 22 are inserted into the limit frame 25. The bottom of the limit frame 25 is installed on the bottom of the head section 11 through the limit frame 24. A motor 26 is provided on one side of one of the transmission frames 23. The output end of the motor 26 is connected to a rocker 27. The outer end of the rocker 27 is provided with a transmission rod 28, and the transmission rod 28 penetrates into the transmission frame 23.

[0025] Specifically, the reciprocating scraper 21 is made of rubber material, which can scrape off the mud and sand on the belt without causing damage to the belt itself; the motor 26 is started while the belt is conveying, and the motor 26 drives the transmission rod 28 to make a circular motion through the rocker 27. The transmission rod 28 drives the transmission frame 23 to move during the movement. Since the translation rod 22 is restricted by the limit frames 25 on both sides thereof, the transmission rod 28 can only drive the translation rod 22 to translate left and right through the transmission frame 23, and the transmission rod 28 moves up and down in the through groove in the transmission frame 23 when rotating; the internal through groove height of the transmission frame 23 is greater than the distance between the highest end and the lowest end of the movement trajectory of the transmission rod 28; the extension length of the reciprocating scraper 21 is greater than the width of the conveying belt.

[0026] Specifically, after the mud and sand on the belt reaches the position of the reciprocating scraper 21, it is subjected to the vertical force from the reciprocating scraper 21, and it is difficult for the mud and sand to pass through the gap between the belt and the reciprocating scraper 21, so it is retained on the upper surface of the reciprocating scraper 21 and slides down along the reciprocating scraper 21 to the head dust collection box 5 below; because the transmission rod 28 drives the reciprocating scraper 21 to move left and right, the blade of the reciprocating scraper 21 moves left and right on the belt surface, and the speed of the belt itself is coordinated, so that the mud and sand on the belt are not only subjected to the original vertical force of the reciprocating scraper 21, but also to its lateral shear force, so that the mud and sand are easier to fall off, thereby improving the scraping effect of the reciprocating scraper 21 and reducing the pressure of the subsequent cleaning process.

[0027] The second scraping device 3 includes a carbide scraper 31 and a chain cleaner 32. The blade of the carbide scraper 31 abuts against the bottom belt of the flat slope section 12. The bottom of the carbide scraper 31 is fixed to one side of the chain cleaner 32. The conveying terminal of the chain cleaner 32 faces one side of the reciprocating scraper 21. The lower part of the conveying terminal of the chain cleaner 32 supports the machine head dust collection box 5, which is also located directly below the reciprocating scraper 21.

[0028] Specifically, a carbide scraper 31 is arranged below the flat slope section 12 to perform secondary cleaning on the belt, so that the sand on the belt can be removed more thoroughly; the sand and dust that fall off are swept into the head dust collection box 5 by the chain cleaner 32 after falling.

[0029] A corridor tile floor 6 is provided directly below the corridor section 13, and the surface of the corridor tile floor 6 has the same inclination direction as the corridor section 13. An organic tail dust collection box 7 is supported directly below the lower end of the corridor tile floor 6, and a flushing nozzle 4 is provided directly above the higher end of the corridor tile floor 6. A plurality of flushing nozzles 4 are provided and arranged in parallel, and the water outlet of the flushing nozzle 4 faces the corridor tile floor 6.

[0030] Specifically, the inclination angle of the corridor section 13 is between 8° and 14°, and a 200mm / 300mm brick cofferdam is provided on the side of the corridor tile floor 6. The flushing nozzle 4 adopts the "regular water injection and dust unloading" mode to wash the dust dropped by the belt on the corridor tile floor 6. The dust unloading frequency and duration are 40min×4 times / day, and the flushing sewage is collected in the tail dust collection box 7, thereby realizing automatic cleaning of the corridor section 13 floor without manual cleaning, avoiding long-term exposure to dust and endangering the health of employees, saving manpower while also ensuring the personal safety of employees.

[0031] Working principle: After the belt reaches the head section 11, the motor 26 drives the reciprocating scraper 21 to translate left and right, and cooperates with the speed of the belt itself, so that the mud and sand attached to the belt are simultaneously subjected to vertical and horizontal forces, making it easier for the mud and sand to fall off the belt surface, thereby improving the mud and sand scraping effect of the first scraping process, and the scraped mud and sand fall into the head dust collection box 5; after the belt reaches the flat slope section 12, the carbide scraper 31 performs a second scraping operation on the belt, and the fallen mud and sand are swept into the head dust collection box 5 by the chain sweeper 32; when the belt passes through the corridor section 13, the dust that falls on the corridor tile floor 6 is flushed into the tail dust collection box 7 by the flushing nozzle 4, thereby completing the mud and sand scraping and cleaning operation of the belt, ensuring the stable operation of the belt conveyor 1.
