Description

Technical Field

[0001] The invention relates to the technical field of coal mining, in particular to a special coal conveying and cooling device for coal mines. Background Art

[0002] Coal is the most important solid fuel and a type of combustible organic rock. Coal is formed by lush plants that grow in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried in water or mud. It is formed by natural coalification over a long geological period. During coal mining, coal is obtained by crushing, which releases a large amount of heat, causing the temperature of the newly mined coal to be too high, which is not conducive to subsequent processing. This requires the use of a cooling setting to cool the coal.

[0003] At present, the existing coal transportation and cooling mechanism for coal mines (patent application number: CN202111560308.8) includes a shell, a feed port is fixedly installed on the upper part of the shell, a crushing mechanism is installed in the feed port, a rotating shaft is vertically rotatably installed on the top surface of the shell, a power mechanism is installed on the upper outer wall of the rotating shaft, the power mechanism includes a first pulley fixedly sleeved on the outer wall of the rotating shaft, a second motor with an output shaft rotating and penetrating the shell is vertically fixedly installed on the upper end surface of the upper wall of the shell, and the output shaft of the second motor rotates and penetrates the protective plate, the protective plate is used to protect the first belt and other components to prevent the falling coal mine fragments from constantly hitting the first belt, and also plays a role in dispersing the coal mine fragments. The outer wall is fixedly sleeved with a second pulley, the second pulley is connected to the first pulley through the first belt, the first pulley and the second pulley are both located below the protective plate, and a plurality of stirring rods are fixedly installed transversely on the outer wall of the lower part of the rotating shaft. The stirring rods promote the mixing of coal crushed material and water, accelerate the water cooling of coal crushed material, and also accelerate the dissolution of soil and water, thereby improving the efficiency of coal mine cleaning. The inner wall of the shell is transversely fixedly connected with an inclined protective plate through a transversely fixed connecting rod, the cross-section of the protective plate is L-shaped, the rotating shaft rotates through the protective plate, a discharge pipe is vertically fixedly installed at the lower part of the shell, a valve is installed at the upper end of the discharge pipe, and a valve is fixedly connected to the lower end of the discharge pipe. An obliquely arranged transport pipe has a transport mechanism installed in it, a water outlet is provided at the bottom of the lower end of the transport pipe, water is discharged from the lower end of the transport pipe, and material is discharged from the upper end, so that the crushed material and water are separated, and the function of the device is ensured; a base frame is horizontally arranged below the higher end of the transport pipe, and both ends of the upper end surface of the base frame are horizontally rotatably connected to conveying rollers through vertically fixed brackets, and the two conveying rollers are connected through a conveyor belt transmission, and a driving mechanism is installed on the shaft of one of the conveying rollers, and the driving mechanism includes a driven pulley fixedly sleeved on the outer side wall of the shaft of the conveying roller, and a fourth motor is horizontally fixedly installed on the upper end surface of the base frame, and a driving pulley is fixedly sleeved on the outer side wall of the output shaft of the fourth motor The driving pulley is connected to the driven pulley through a second belt, and a fixing frame is arranged above the conveyor belt, and the upper end surface of the fixing frame is provided with a through slot, and a turbofan is rotatably installed in the slot. A supporting plate which is slidably matched with the lower end of the upper layer of the conveyor belt is laterally fixedly installed on the inner side wall of the fixing frame, and a blocking plate which is slidably matched with the outer side wall of the conveyor belt is vertically fixedly installed on the upper end surface of the supporting plate, and the blocking plate is used to block the coal crushed materials and prevent the coal crushed materials from falling from both sides of the conveyor belt. Bottom columns are vertically fixedly installed on the lower surfaces of the shell and the transport pipe, and the lower part of the shell is in the shape of an inverted truncated cone. The shape design of the lower part of the shell makes it more convenient to discharge the crushed materials.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. Complicated implementation: The existing coal transportation and cooling mechanism for coal mines needs to occupy a certain space when in use, and also takes a lot of time and effort to install, which affects the convenience of using the device. Moreover, it is also necessary to change the processing sequence of the original coal mine, so the original assembly line needs to be adjusted, which leads to cumbersome use. Secondly, it also increases the time of coal processing, affecting the efficiency of coal processing;

[0006] 2. Waste of water resources: When the existing coal mine coal transportation and cooling mechanism is in use, the transport pipe is tilted so that water and coal move in different directions. However, since the transport pipe is tilted downward, water flows out to the downward end of the transport pipe under the action of gravity (water keeps flowing out), and this causes the water intake inside the shell to be greater than the water discharge of the transport pipe, otherwise the water inside the shell cannot fully contact the coal, making it impossible to remove the mud and sand on the surface of the coal. Secondly, the crushed coal is easy to clog the gap between the feeding screw and the transport pipe, resulting in an increase in the resistance to the rotation of the feeding screw, which affects the service life of the device.

[0007] 3. Unable to continuously cool down: The existing coal transportation and cooling mechanism in coal mines only passes the coal through water when in use. However, due to the high internal temperature of the coal during mining, it is difficult to lower the temperature by only cooling it in a short period of time. This results in the need to cool down or process the coal again in the future, which seriously affects the use effect of the device. Secondly, if long-term gold immersion is used for cooling, although it can play a cooling role, the time required for cooling affects the timely transportation of coal.

[0008] In order to solve the above problems, patent document CN202222726541.5 discloses a coal transportation and cooling mechanism for coal mines, which includes: a conveyor belt, with baffles installed on both sides; a cooling component installed on the top of the conveyor belt; wherein the cooling component includes a connecting plate, and side plates are installed on both sides of the connecting plate, the connecting rod of the side wall of the side plate is plugged into the connecting plate, and the side wall of the side plate is installed with an "L"-shaped hook plate, and the cooling component is connected to the baffle through the hook plate; the side wall of the side plate is installed with multiple nozzles. The coal transportation and cooling mechanism for coal mines described in the utility model adopts a side plate with a hook plate, and the side plate can be freely expanded or retracted, so it effectively solves the cumbersome technical problems of the existing coal transportation and cooling machine for coal mines when in use, thereby achieving the purpose of rapid installation, and at the same time, there is no need to adjust the coal production line, only adjustments need to be made on the basis of the original equipment, which is simple and convenient.

[0009] However, the above-mentioned cooling structure still has certain defects. On the one hand, the uniformity of coal on the conveyor belt cannot be guaranteed during transportation. Once the coal is thick, a good cooling effect cannot be guaranteed. On the other hand, the cooling process will continue to produce wastewater. If this wastewater cannot be effectively treated, it will pollute the coal mine environment and cause a waste of water resources. More importantly, the above-mentioned technology cannot adjust the cooling process in real time according to the temperature of the coal, resulting in poor cooling effect.

[0010] Therefore, there is an urgent need for a special coal conveying and cooling equipment for coal mines that can solve the above problems. Summary of the invention
