It is a very important energy source and an important raw material for metallurgy and chemical industry. It is classified into lignite, bituminous coal, anthracite and semi-anthracite. Coal is a non-renewable resource. Coal is a solid combustible mineral gradually formed by ancient plants buried underground and undergoing complex biochemical and physicochemical changes. It is a solid combustible organic rock, mainly formed by plant remains through biochemical action and geological action after burial. It is commonly known as coal.

[0003] In the process of transporting coal raw materials, in order to avoid dust, most of them will install a water spraying device on the belt conveyor to spray water on the coal raw materials on the belt conveyor to wet its outer surface.

[0021] 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.

[0022] Reference Figure 1-Figure 4 A coal mine raw material conveying device comprises a conveyor body 1, a water spray dust suppression device 2, and a water supply pipeline 3. The conveyor body 1 adopts a belt conveyor for transporting coal mine raw materials. The water spray dust suppression device 2 is installed on a bracket in the conveyor body 1 and is used to spray water droplets on the coal mine raw materials on the belt conveyor to prevent dust mixed in the coal mine raw materials from being raised.

[0023] In a further embodiment, in order to avoid raising dust during the transportation of coal raw materials, a water spraying device is usually installed on the belt conveyor to spray water onto the coal raw materials on the belt conveyor to wet its outer surface. However, the above operation will result in muddy water mixed with water from dust adhering to the belt of the belt conveyor, black water mixed with water from sundries on the outer surface of the coal, etc. These sewage need to be cleaned. The belt conveyor includes a plurality of inner rollers, and the plurality of inner rollers allow the belt in the belt conveyor to form a shower area 101. The shower area 101 is tilted downward. The shower area 101 is located in the lower half of the belt, and the upper half is used to transport coal raw materials. In order to clean the sewage adhering to the belt, a shower nozzle 4 is provided on the lower side of the shower area 101. The shower nozzle 4 is connected to the water supply pipe 3. The water supply pipe 3 penetrates the collecting box 5. The collecting box 5 is fixedly installed on the bracket of the belt conveyor, such as Figure 3 As shown, the shower port of the shower nozzle 4 forms an acute angle with the upper part of the shower area 101. After the water is sprayed out through the shower nozzle 4, it is sprayed toward the shower area 101. After rebounding in the shower area 101, the water will rush down to the lower left side and enter the inside of the collection box 5. The sewage on the outer surface of the belt is rinsed at the above angle, so that the sewage after cleaning the belt can enter the collection box 5 to avoid splashing everywhere, which is convenient for maintaining the sanitary environment in the collection box 5 area. The upper end surface of the collection box 5 is fixedly installed There is a scraper 6, the upper end surface of the scraper 6 is against the outer surface of the belt in the belt conveyor, a triangular inclined block 7 is installed inside the collecting box 5, and a flushing nozzle 8 parallel to the inclined side is installed on the inclined side of the triangular inclined block 7, and the flushing nozzle 8 is connected to the water supply pipe 3. The water flowing in the water supply pipe 3 is sprayed out through the flushing nozzle 8, and the sprayed water flows along the inclined surface of the triangular inclined block 7, and finally flows out from the opening of the collecting box 5. An opening is set in the collecting box 5, and an opening baffle 9 is detachably installed at the position of the opening;

[0024] The sewage on the belt of the belt conveyor is washed away by the flushing nozzle 4. Although some of the water can be scraped away after passing through the position of the scraper 6, the outer surface of the belt is still wet. Therefore, an outer roller 103 is provided on the belt conveyor. The outer roller 103 and the inner roller form a sinking area 102 together. There are two outer rollers 103, and the two outer rollers 103 are respectively located on both sides of the sinking area 102. A groove is provided in the middle part of the outer roller 103 near the flushing area 101. The outer surface of the belt in the sinking area 102 is attached with a wiping cloth 10, and the wiping cloth 10 is installed On the shaping plate 11, the shape of the shaping plate 11 is the same as the shape of the sinking area 102, which plays the role of fixing the wiping cloth 10 to prevent the wiping cloth 10 from shifting when wiping the belt. A plurality of through holes are arranged on the shaping plate 11, and the through holes are connected to the heating box 12. A heating device for heating air is arranged in the heating box 12. The heating box 12 is connected to the air intake duct 13, and the air intake duct 13 can deliver the outer gas into the heating box 12. After being heated by the heating box 12, the gas is discharged from the wiping cloth 10 to accelerate the volatilization speed of the moisture at the belt. The heating box 12 is fixedly mounted on the bracket of the conveyor body 1.
