Description

Technical Field

[0001] The present invention relates to the technical field of coal transportation, and in particular to a coal separation and transportation device and method. Background Art

[0002] Coal is a solid combustible mineral that was gradually formed when ancient plants were buried underground and underwent complex biochemical and physicochemical changes. It is mainly composed of elements such as carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, of which carbon is the most important component, and its content can range from about 70% in lignite to more than 90% in anthracite. In ancient times, a large number of plants accumulated in environments such as swamps. Due to the movement of the earth's crust, these plant remains were buried underground. In the oxygen-deficient environment underground, the plant remains first underwent biochemical changes and were decomposed by microorganisms to form peat. As time passed and the strata further sank, the peat was subjected to high temperature and high pressure, gradually lost water, and coalification occurred. This process starts with peat, passes through lignite and bituminous coal, and may eventually form anthracite. The degree of coalification becomes higher and higher, and the properties of coal also change accordingly.

[0003] When separating and transporting coal, existing devices will generate a large amount of coal ash dust when separating coal, which will float around the device in large quantities.

[0005] The beneficial effects of the present invention are as follows: 1. The present invention sets a cooling component. When performing separation work, coal of different sizes is separated from the separation shell in sequence and falls into the corresponding blanking shell in sequence. The coal entering the blanking shell slides downward in the blanking chute. By turning on the water pump, the water flow in the water tank is brought into the spray box through the water pump, and the water flow in the spray box is sprayed out through the spray head. Therefore, when the coal is separated, the coal entering the blanking chute is sprayed and cooled, thereby avoiding the generation of a large amount of dust when the coal is separated, and avoiding the phenomenon of high spontaneous combustion temperature of the coal when the separation work is performed.

[0006] 2. The present invention sets a spiral component, continuously puts coal into the feed port, turns on the motor, drives the spiral blades through the output end of the motor, and rotates in the separation shell and the connecting shell, so that the spiral blades drive the coal into the separation shell, and the separation mechanism screens the coal, thereby separating coal of different sizes.

The present invention sets a separation mechanism, so that when the coal is screened, the particle size distribution of the coal may be different in different coal mines or at different mining stages of the same coal mine. The size of the drop hole can be adjusted so that the separation mechanism can adapt to such changes. If the mined coal particles are generally large, the drop hole can be enlarged so that the separation mechanism can work normally and avoid drop holes due to large particles. On the contrary, if the coal particles are small, reducing the drop hole can better separate coal of different particle sizes. For example, in the early stage of coal mining, the coal particles may be large due to the mining method or the characteristics of the coal seam, and a larger drop hole is used for preliminary screening. As the mining progresses, the coal particle size becomes smaller. At this time, the drop hole is adjusted to be smaller to adapt to the new particle size distribution to ensure that the screening work is carried out continuously and effectively.

[0008] 4. The present invention sets the angle of the rubber plate to be greater than that of the scraper by providing a contact mechanism, so that when the conveyor belt is conveying, the rubber plate can move against the side of the conveyor belt, and at the same time, the rubber plate can clean the side of the conveyor belt, so as to scrape off the coal slag and coal ash attached to the side of the conveyor belt. At the same time, when the coal slag is stuck in the conveyor belt, the scraper is used to squeeze and clean the coal slag, so that the scraper cleans and scrapes off the coal slag stuck on the conveyor belt. At the same time, when the extrusion force between the scraper and the coal slag stuck on the conveyor belt is greater than the tensile force of the connecting spring, the fixed frame moves downward through the connecting rod, and at the same time, the buffering work of the connecting spring is used to avoid excessive extrusion force between the scraper and the conveyor belt, which will cause extrusion damage to the side of the conveyor belt.

At the same time, when the extrusion force between the scraper plate 347 and the coal slag stuck on the conveyor belt 33 is greater than the tensile force of the connecting spring 345, the fixing frame 341 moves downward through the connecting rod 342, and at the same time, the buffering work of the connecting spring 345 is used to avoid excessive extrusion force between the scraper plate 347 and the conveyor belt 33, thereby causing extrusion damage to the side of the conveyor belt 33. Embodiment 4, use Figure 1-Figure 8 A coal separation and transportation device of the present invention is described as follows; like Fig. 9 A method for separating and transporting coal according to the present invention comprises the following steps: S1: by continuously placing the coal in the spiral component 2, the spiral component 2 sequentially separates the coal; S2: When separating the coal, the cooling component 4 can cool and dust the coal being screened in the spiral component 2; S3: The separated coal can be transported by the transport component 3 for subsequent transportation.

[0011] The specific workflow is as follows: When working, the coal is placed in the spiral component 2 and separated by the spiral component 2, so that the separated coal can be subsequently transported by the conveying component 3. At the same time, when the coal is separated, the coal screened in the spiral component 2 can be cooled by the cooling component 4. By continuously putting coal into the feed port 24, and turning on the motor 23, the spiral blade 26 is driven by the output end of the motor 23 to rotate in the separation shell 211 and the connection shell 22, so that the spiral blade 26 drives the coal into the separation shell 211, and the separation mechanism 21 is used to screen the coal, so that coal of different sizes is separated; The spiral blade 26 drives the coal into the separation shell 211. The side of the separation shell 211 is provided with drop holes 216 evenly opened from small to large. When the coal is driven by the spiral blade 26 to pass through the drop holes 216 on the separation shell 211, the coal can be screened at multiple levels, thereby separating and collecting coal of different sizes. At the same time, when it is necessary to adjust the size of the drop hole 216, the output end of the electric hydraulic cylinder 212 drives the slider 214 to move in the sliding groove 213 through the connecting shaft 215, and at the same time drives the sliding sleeve 217 in the separation shell 214. The sliding sleeve 217 slides on the inner side of the housing 211, and the adjusting grooves 218 are opened on the side of the sliding sleeve 217 in the order from small to large according to the drop holes 216. At the same time, the adjusting grooves 218 are set in order from small to large, and then the sliding sleeve 217 is driven by the slider 214 to slide on the side of the separation housing 211. At the same time, the adjusting grooves 218 overlap with the drop holes 216, and the aperture size of the drop holes 216 is adjusted, so that corresponding adjustments can be made according to a variety of different usage scenarios. The coal discharged through the drop holes 216 of different sizes enters the corresponding drop grooves 46 for subsequent transportation. Therefore, when screening coal, the particle size distribution of coal may be different in different coal mines or different mining stages of the same coal mine. The size of the drop hole 216 can be adjusted so that the separation mechanism 21 can adapt to this change. If the mined coal particles are generally large, the drop hole 216 can be enlarged to enable the separation mechanism 21 to work normally and avoid the drop hole 216 being caused by the particles being too large. On the contrary, if the coal particles are small, the drop hole 216 can be reduced to better separate coal of different particle sizes. For example, in the early stage of coal mining, the coal particles may be large due to the mining method or the characteristics of the coal seam, and a larger drop hole 216 is used for preliminary screening. As the mining progresses, the coal particle size becomes smaller. At this time, the drop hole 216 is adjusted to be smaller to adapt to the new particle size distribution and ensure the continuous and effective screening work. During the separation process, coals of different sizes are separated out of the separation shell 211 in turn and fall into the corresponding blanking shells 42 in turn. The coals entering the blanking shell 42 slide downward in the blanking chute 46. By turning on the water pump 43, the water flow in the water tank 41 is brought into the spray box 44 through the water pump 43, and the water flow in the spray box 44 is sprayed out through the spray head 45. Thus, when the coal is separated, the coal entering the blanking chute 46 is sprayed to cool down, thereby avoiding a large amount of dust during the separation process and avoiding the high spontaneous combustion temperature of the coal during the separation process. During the separation process, due to the special properties of these high-sulfur or high-volatile coals, if the heat generated by oxidation cannot be dissipated in time, it will accumulate inside the coal or in a corner of the separation equipment. When the high-sulfur coal is accumulated near the separation shell 211 waiting for screening, or when it is accumulated at the edge of the separation shell 211, heat may accumulate here. As the temperature continues to rise, it may eventually cause the coal to spontaneously combust. The coal after spraying and cooling falls onto the conveyor belt 33 through the bottom of the blanking shell 42, and the conveyor belt 33 is driven by the transmission mechanism 32 to rotate on the bracket 31, so as to transport the corresponding separated and blanked coal. At the same time, when the coal is transported, when there are coal impurities stuck on the conveyor belt 33, the coal stuck on the conveyor belt 33 is in friction contact with the coal on the conveyor belt 33 for a long time, and the coal spontaneously ignites. By arranging a contact mechanism 34 at the bottom of the conveyor belt 33, the contact mechanism 34 and the conveyor belt 33 are in contact and cleaned; When the conveyor belt 33 is conveying on the inner side of the bracket 31, the conveyor belt 33 is in contact with the rubber plate 348 and the angle of the rubber plate 348 is set to be greater than the scraper 347. Thus, when the conveyor belt 33 is conveying, the rubber plate 348 can move against the side of the conveyor belt 33. At the same time, the rubber plate 348 can clean the side of the conveyor belt 33, thereby scraping off the coal slag and coal ash attached to the side of the conveyor belt 33. At the same time, when the coal slag is stuck in the conveyor belt 33, The scraper 347 is used to squeeze and clean the coal slag, so that the scraper 347 can clean and scrape off the coal slag stuck on the conveyor belt 33. At the same time, when the squeezing force between the scraper 347 and the coal slag stuck on the conveyor belt 33 is greater than the tensile force of the connecting spring 345, the fixed frame 341 moves downward through the connecting rod 342. At the same time, the buffering work of the connecting spring 345 is used to avoid excessive squeezing force between the scraper 347 and the conveyor belt 33, which will cause squeezing damage to the side of the conveyor belt 33.
