[0002] In order to reduce coal dust, water is sprayed on the mined coal during the process of conveying it through the conveyor. However, in the low temperature environment of winter, the water that is not absorbed by the coal stays on the conveyor and freezes, which not only causes the coal to stick to the conveyor, but also may cause the coal blocks to freeze together during transportation, increasing the volume of the whole block, making it difficult for them to leave the conveyor and enter the collection bin or carriage.

[0038] Production system process flow:

[0039] According to the system process flow, the entire system is divided into three parts: coal receiving system, coal storage system and loading system.

[0040] 1. The coal receiving system is the part from the weighing of coal transport vehicles to the storage and transfer station. It includes the weighing room, the coal receiving station, the 120 belt, the storage and transfer receipt, etc. The coal receiving station is designed with 4 coal receiving pits with a capacity of 100t; the 120 belt is 1.4m wide, about 155m long, with a slope of 16.5 degrees, a lifting height of 35.3m, a belt speed of 2.5m / s, and a coal transport capacity of 1500t / h.

[0041] 2. The coal storage system is the above-ground part from the storage and transfer station to the coal storage shed. It includes the storage and transfer station, 201 belt, coal storage shed, main and auxiliary coal receiving hoppers, etc. The coal storage shed is 180m long, 70m wide, 29m high, 23m high, and has a storage capacity of 100,000 tons. There are 5 main coal receiving hoppers in the coal storage shed and 8 auxiliary coal receiving hoppers on both sides; the 201 belt is 1.4m wide, about 158m long, with a belt speed of 2.5m / s, and a coal transportation capacity of 1500t / h.

[0042] 3. The loading system is the part from the 815 belt blind passage to the fast loading station (inclusive). It includes the loading and transfer station, 815 belt, 820 belt, fast loading station, etc. The 815 belt is located at the lower side of the coal storage shed. The belt is 2m wide, about 172m long, with a belt speed of 4m / s and a coal transportation capacity of 5000t / h; the 820 belt is 2m wide, about 236m long, with a slope of 11.2 degrees, a lifting height of 43.3m, a belt speed of 4m / s, and a coal transportation capacity of 5000t / h; the fast loading station is equipped with a buffer warehouse with a capacity of 300t and a quantitative warehouse with a capacity of 100t. The loading speed is that the loading time of each carriage does not exceed 45s. Under normal circumstances, the loading of the entire train does not exceed 45min.

[0043] The specific operation process is:

[0044] After the coal truck enters the yard, the weight is weighed and recorded on the heavy truck scale. After the weight check, the truck enters the coal receiving station to unload the coal. After unloading, the truck leaves the coal receiving station and leaves the yard after being weighed and recorded on the empty truck scale.

[0045] The coal unloaded at the receiving station leaks from the coal pit to the 120 belt, which transfers the coal to the 201 belt above the coal storage shed through the storage transfer station. The 201 belt is equipped with an electric double-sided plow-type unloader along the way, which unloads the coal to the designated location of the coal storage shed according to the situation. The coal in the coal storage shed is transported to the 815 belt in the underground tunnel through the activated vibrating coal feeder, and the 815 belt is transferred to the 820 belt through the loading and transfer station, and then transported to the fast quantitative loading station through the 820 belt, and then loaded on the train through the loading station for transportation.

[0046] When the present invention is used, the conveyor belt 1 is installed as follows: Figure 1 As shown, the present invention is installed at the junction area between conveyor belt 1 and conveyor belt 2 7.

[0047] During operation, coal is poured onto the conveyor belt 2 7. When the coal is transported to the conveyor belt 1 through the conveyor belt 2 7, the external spray system will wet the coal to reduce the dust of coal powder. At this time, the coal is in a wet state, and the water not absorbed by the coal during the spraying process stays on the conveyor belt 1. In order to prevent the wet coal from freezing on the conveyor belt 1 at low temperatures, the present invention is equipped with a spray tank 3 and a spreading box 4. When the conveyor belt 1 rotates to the lower side of the installation frame 101, the spray tank 3 sprays antifreeze liquid onto the conveyor belt 1 to prevent the wet coal from freezing on the conveyor belt 1, which also helps the subsequent cleaning of the conveyor belt 1.

[0048] Furthermore, since the conveyor belt 1 is designed in a U shape, with the left and right sides higher and the middle lower, when the antifreeze is sprayed on the conveyor belt 1, the antifreeze will gather in the middle of the conveyor belt 1, which may cause the coal on the inclined surfaces on both sides to still adhere to the conveyor belt 1. Therefore, after the spray tank 3 sprays the antifreeze, a layer of coal powder is sprinkled on the conveyor belt 1 through the spreading box 4, so that the coal powder and the antifreeze are mixed to form an isolation layer to prevent the antifreeze from gathering in the middle of the conveyor belt 1 and avoid the coal on the inclined surfaces on both sides from adhering.

[0049] In addition, when the spray system on the conveyor belt 2 7 wets the coal, some of the water that is not absorbed by the coal will remain on the conveyor belt 1. Due to the U-shaped structure of the conveyor belt 1, the water that is not absorbed by the coal gathers in the middle of the conveyor belt 1, washing away the isolation layer on the inclined surfaces on the left and right sides of the conveyor belt 1, causing the conveyor belt 1 to be exposed. In order to solve this problem, the present invention is designed with a spreading box 2 6. After the spreading box 4 has spread the coal powder, a layer of coal slag is spread on the conveyor belt 1 through the spreading box 2 6 to increase the thickness of the isolation layer of the conveyor belt 1, and the coal slag absorbs the water that has not been completely absorbed by the coal transferred from the conveyor belt 2 7 to the conveyor belt 1, thereby preventing the water that has not been completely absorbed by the coal from washing the isolation layer on the inclined surfaces on the left and right sides of the conveyor belt 1.

[0050] Furthermore, the isolation layer formed by the liquid spray box 3, the material spreading box 1 4 and the material spreading box 2 6 effectively solves the freezing and dust problems that may be encountered by the coal during the conveyor belt transfer process. However, the top layer of the isolation layer is dry coal powder or coal slag. Due to the height difference between the conveyor belt 1 and the conveyor belt 2 7, a certain impact force will be generated when the coal falls from the conveyor belt 2 7 to the conveyor belt 1, which may cause the dry coal slag or coal to be lifted up, resulting in the destruction of the isolation layer. Therefore, the present invention adds a liquid spray box 3 on the front side of the material spreading box 2 6. The function of this liquid spray box 3 is to spray another layer of antifreeze on the isolation layer. This has two advantages: on the one hand, it can wet the coal slag and coal powder, and reduce the dust caused by the impact force caused by the height difference; on the other hand, it can also enhance the antifreeze effect of the antifreeze on the coal, ensuring that the coal will not freeze on the conveyor belt in a low temperature environment.

[0051] Furthermore, since the coal needs to be transported over a long distance, the problem of freezing becomes more serious. During the transportation process, due to the low temperature environment, the moisture on the conveyor belt 1 will freeze, which will cause the coal on the conveyor belt 1 to adhere to each other, causing the coal blocks to stick together to form large blocks, forming large coal blocks that are difficult to handle. These large coal blocks are not easy to separate from the conveyor, which in turn affects the normal unloading of the coal, whether it enters the collection bin or the carriage. In order to solve this problem, the present invention is provided with a spray rack 107. When the conveyor belt 1 drives the coal to move from back to front, the slider on the electric slide rail 106 drives the spray rack 107 to move left and right. This movement mode enables the spray rack 107 to evenly and massively pour antifreeze on the conveyor belt 1. The pouring mode of the antifreeze is Z-shaped. This special pouring mode can effectively separate the coal on the conveyor belt 1 into small pieces, and prevent the coal from sticking into large pieces due to mutual contact.

[0052] The above working principle of the present invention is to spray antifreeze liquid onto the conveyor belt 1 through the liquid spray box 3, and at the same time, the material spreading box 14 and the material spreading box 26 sprinkle coal powder and coal slag onto the conveyor belt 1, which work together to form an effective isolation layer. It prevents water and wet coal from contacting the conveyor belt 1, causing the coal to be frozen on the conveyor belt 1. Secondly, by moving the liquid spray rack 107 left and right, pouring the antifreeze liquid, the antifreeze liquid forms a Z-shaped distribution on the conveyor belt 1, and effectively separates the contacted coal into small pieces. It avoids the formation of large blocks of carbon blocks due to adhesion when water freezes on the conveyor belt 1, which will make it difficult to separate the coal from the conveyor, thereby affecting its smooth entry into the collection bin or carriage.

[0053] Furthermore, when the coal is transferred from the conveyor belt 27 to the conveyor belt 1, it moves along a parabolic trajectory, so the coal that falls on the conveyor belt 1 will be far away from the installation frame 101. However, the water flow on the conveyor belt 27 used to wet the coal will fall directly along the conveyor belt 27, causing the isolation layer formed on the conveyor belt 1 to be dispersed by the water flow falling from the conveyor belt 27 before it comes into contact with the coal, causing the wet coal and water to directly contact the conveyor belt 1, causing the coal to be frozen on the conveyor belt 1. This situation causes the wet coal and water to directly contact the conveyor belt 1, which in turn causes the coal to freeze on the conveyor belt. Therefore, the present invention is designed with a coal blocking plate 301 and an intercepting plate 302. When the coal falls from the conveyor belt 27, it will first fall on the coal blocking plate 301, and the DD motor drives the coal blocking plate 301 to rotate, and the coal blocking plate 301 can effectively control the flow of the coal. When the drainage trough 3001 rotates to the lower side, the coal in the drainage trough 3001 falls onto the lower coal blocking plate 301. At this time, the lower coal blocking plate 301 is driven to rotate by the DD motor. When the drainage trough 3001 rotates to the lower side, the coal falls onto the conveyor belt 1. In this process, since the coal blocking plate 301 is tilted from left to right, the water in the drainage trough 3001 flows through the interception plate 302 through the guidance of the drainage trough 3001 and is collected by the collection trough on the right side of the interception plate 302. The coal blocking plate 301 is double-layered and the upper and lower coal blocking plates 301 are staggered, which further improves the guiding and filtering effect of the water flow, and avoids the water flow on the conveyor belt 27 used to wet the coal directly flowing into the conveyor belt 1 and flushing the isolation layer on the conveyor belt 1, thereby preventing the subsequent parabolic falling coal from directly contacting the conveyor belt 1, ensuring that the coal will not be frozen on the conveyor belt 1 when transporting coal in a low temperature environment.

[0054] The above-mentioned working of the present invention is to intercept the coal falling from the conveyor belt 27 by the coal blocking plate 301, and to drain the water on the conveyor belt 27 for wetting the coal by the drainage groove 3001 on the inclined coal blocking plate 301, so that the water flows through the intercepting plate 302 and falls on the outside of the conveyor belt 1, thereby preventing the water flowing wetting the coal from directly flowing to the conveyor belt 1 and washing the isolation layer on the conveyor belt 1, thereby preventing the subsequent coal falling in a parabola from directly contacting the conveyor belt 1, and ensuring that the coal will not be frozen on the conveyor belt 1 when transporting the coal in a low temperature environment.

[0055] When the coal on the conveyor belt 1 falls off the front side of the conveyor belt 1, the conveyor belt 1 is in a wet state. As the conveyor belt 1 rotates from the front side to the side close to the conveyor belt 27, wet coal powder may remain on the conveyor belt 1, and there is also a phenomenon of ice. In order to improve the transportation efficiency of the conveyor belt 1, the conveyor belt 1 needs to be cleaned. When the conveyor belt 1 rotates to the upper side of the cleaning box 2, the nozzle 201 automatically sprays water and washes the conveyor belt. The DD motor connected to the nozzle 201 drives the nozzle 201 to drive the bristles to rotate, so that the nozzle 201 can not only spray water, but also effectively physically clean the conveyor belt 1 through the bristles. After being washed by the nozzle 201, the conveyor belt 1 will pass through the first scraper 105, and the first scraper 105 will scrape off the water on the conveyor belt 1. Then the sponge 5 will wipe the conveyor belt 1 to avoid water remaining on the conveyor belt 1, which helps to maintain the effect of the antifreeze. Since the sponge 5 may reduce its drying effect after absorbing water, a suction hole is opened on the lower side of the sponge 5, and a suction pump is connected to the suction hole. The water in the sponge 5 is sucked by the suction pump to avoid a large amount of water remaining in the sponge 5 to reduce the drying effect. The water sucked by the suction pump is discharged into the sewage collection bin on the lower side of the sponge 5 on the cleaning box 2. In addition, a protective plate 104 is provided between the installation frame 101 and the cleaning box 2, which is used to protect the conveyor belt 1 before spraying the antifreeze to prevent other impurities from adhering to the conveyor belt 1 before spraying the antifreeze.

[0056] Furthermore, when flushing the conveyor belt 1, since the conveyor belt 1 is adhered with coal powder, if the water flow after direct flushing flows to the ground, it may cause pollution to the environment. In order to avoid this situation, a sewage collection bin is provided on the cleaning box 2, and a drainage hole is opened on the cleaning box 2. A suction pump is provided in the sewage collection bin. The suction pump is used to suck the flushed water into the sewage collection bin through the drainage hole, so as to avoid the flushed sewage flowing directly to the ground and polluting the environment. When the sewage collection bin is full, it is pumped away by an external water pump through the connecting pipe on the sewage bin. Secondly, during the process of the conveyor belt 1 moving to the upper side of the cleaning box 2, due to the wet state of the conveyor belt 1 and the possible long-distance outdoor work, debris such as plastic fragments may adhere to the conveyor belt 1. These debris may fall on the surface of the cleaning box 2 after flushing, blocking the drainage hole and affecting the drainage effect. Therefore, a second scraper 202 is provided. When the nozzle 201 rotates, the second scraper 202 is driven to rotate, and the plastic debris remaining on the cleaning box 2 is moved to prevent the plastic debris from clogging the drainage holes on the cleaning box 2 and affecting the drainage effect.

[0057] It should be noted that in order to ensure that the conveyor belt 1 can still be effectively cleaned under low temperature conditions, the water used by the nozzle 201 of the present invention is first pumped into the heating water tank 102 provided on the cleaning box 2 through a water pump. In the heating water tank 102, the water flow will be heated to ensure the cleaning effect of the conveyor belt 1 under low temperature conditions. After the cleaning work is completed, there may be residual moisture on the surface of the nozzle 201 and the cleaning box 2. In a low temperature environment, the residual moisture is easy to freeze, which may cause the equipment to be unable to be used normally. Therefore, a heating wire is provided on the cleaning box 2 of the present invention, and the cleaning box 2 is made of heat-conducting material, which effectively prevents the cleaning box 2 and the nozzle 201 from freezing in a low temperature environment, ensuring that the equipment can maintain normal operation even in cold conditions.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
