[0002] Belt conveyors are important equipment in coal ports and mines. Coal, ore and other materials are transported through belt conveyors. With the development of society, the use of coal is increasing, and the use of belt conveyors is also increasing, saving labor and improving work efficiency. During the use of belt conveyors, a large amount of dust is generated, causing environmental pollution. Workers can breathe in dust for a long time, which is harmful to their health.
[0003] Nowadays, during the use of belt conveyors, a large amount of dust will be generated due to the friction, collision and impact caused by the drop between coal or other bulk materials and the belt. This not only affects the working environment, but also makes workers susceptible to occupational diseases such as pneumoconiosis due to long-term exposure to high-concentration dust environments. This is because fine dust particles are inhaled into the lungs, deposited and cause fibrosis of lung tissue, seriously affecting respiratory function. When dust enters the interior of mechanical equipment, it will accelerate component wear, shorten the service life of the equipment, and increase maintenance costs. Utility Model Content

The sealing shell 1 and the dust cover 2 are the basic structures of the whole environmental protection sealing device. The sealing shell 1 is constructed around the feed port of the belt conveyor body 8 to form a closed space, which effectively prevents dust from leaking out. The dust cover 2 is installed on one side of the sealing shell 1, and is mainly used to further block the dust generated during the transportation process. The feed pipe 6 is used for the introduction of materials and is directly connected to the buffer bin 7 on the top of the sealing shell 1. The buffer bin 7 is designed to slow down the falling speed of the material and reduce the dust generated by the impact. And through its position design, it can transfer the material to the belt more smoothly, further reducing the dust.
[0022] like Figure 1 As shown, a plurality of groups of openable and closable door bodies 4 are provided on the sealed shell 1. The design of the plurality of groups of openable and closable door bodies 4 on the sealed shell 1 is convenient for the maintenance, inspection and cleaning of the equipment.

[0024] like Figure 3As shown, a dust suction mechanism is provided on the sealed shell 1, and the dust suction mechanism includes an outer shell 9 and a dust suction end 10. The outer shell 9 is fixedly arranged on the top of the sealed shell 1, and a frame 11 is provided on the inner top of the sealed shell 1, and the dust suction end 10 is fixedly installed on the frame 11. A plurality of dust suction holes 12 are provided on the dust suction end 10, and a first dust suction pipe 13 is fixedly provided on the dust suction end 10. A dust storage bin 14 is provided inside the outer shell 9, and a dustproof plate 15 is embedded inside the dust storage bin 14. A second dust suction pipe 16 is provided outside the dust storage bin 14, and one end of the second dust suction pipe 16 is connected to one end of the first dust suction pipe 13. A plurality of dust suction fans 3 with air outlet ends extending to the outside of the outer shell 9 are fixedly arranged inside the outer shell 9, and the air inlet end of the dust suction fan 3 extends to the inside of the dust storage bin 14. The dust suction end 10 is fixedly installed on the inner top of the sealed shell 1 through the frame 11, and is located on one side of the buffer lower bin 7. The dust suction end 10 is fixedly provided with a dust storage bin 14. The first dust suction pipe 13 and the second dust suction pipe 16 are connected with the dust storage bin 14 in the shell 9. The dust suction fan 3 is the core power source of the dust suction system and is installed inside the shell 9. Its air inlet end penetrates into the dust storage bin 14. As the dust suction fan 3 is started, its air inlet end will absorb the air in the dust storage bin 14 to form a negative pressure inside it, so that the dust suction holes 12 on the dust suction end 10 generate suction, so that it can absorb a large amount of dust generated by collision and drop when the material falls onto the belt, and after the dust-containing air enters the dust storage bin 14, it is filtered by the dustproof plate 15 in the dust storage bin 14, and then discharged outwardly through the air outlet end of the fan. The air outlet end extends to the outside of the shell 9 to achieve air purification and discharge. In this way, the dust generated during the operation can be continuously captured and removed, further improving the dustproof function of the environmental protection sealing device, while ensuring the efficient and stable operation of the equipment and the health and safety of the operators.
[0025] Working principle: The belt conveyor body 8 is located inside the sealing shell 1 and the dust cover 2. It is the core part of material transportation, including the belt, driving device, tensioning device, etc. The belt conveyor environmental protection sealing device is mainly composed of the sealing shell 1 and the dust cover 2. The sealing shell 1 and the dust cover 2 are the basic structure of the entire environmental protection sealing device. The sealing shell 1 is constructed around the feed port of the belt conveyor body 8 to form a closed space to effectively prevent dust from leaking out. The dust cover 2 is installed on one side of the sealing shell 1, mainly used to further block the dust generated during the conveying process. The feed pipe 6 is used to introduce materials and is directly connected to the sealing shell 1. The buffer bin 7 on the top is designed to slow down the falling speed of materials and reduce the dust generated by impact. Its position design can transfer materials to the belt more smoothly, further reducing dust. The multiple sets of openable and closable door bodies 4 on the sealed shell 1 are designed to facilitate the maintenance, inspection and cleaning of the equipment. These door bodies 4 should ensure good sealing in the closed state to prevent dust leakage during operation. At the same time, they can be easily opened when needed to improve the practicality and maintenance efficiency of the equipment. The observation window 5 allows the operator to directly observe the operation of the belt conveyor body 8 without opening the dust cover 2. The running conditions, including the operation of the belt, the flow of materials, and whether there are problems such as blockage and deviation, are helpful to timely discover and solve problems, reduce downtime and maintenance costs. The dust suction end 10 is fixedly installed on the inner top of the sealed shell 1 through the frame 11, and is located on one side of the buffer lower silo 7. The dust suction end 10 is connected to the dust storage bin 14 in the shell 9 through the first dust suction pipe 13 and the second dust suction pipe 16. The dust suction fan 3 is the core power source of the dust suction system and is installed inside the shell 9. Its air inlet end penetrates into the dust storage bin 14. As the dust suction fan 3 is started, its air inlet end will absorb the air in the dust storage bin 14. Air is drawn into the dust collecting bin 14 to form a negative pressure inside the dust collecting bin, thereby causing the dust collecting holes 12 on the dust collecting end 10 to generate suction, so that the dust collecting holes 12 on the dust collecting end 10 can absorb a large amount of dust generated by collision and drop when the material falls onto the belt. After the dust-laden air enters the dust collecting bin 14, it is filtered through the dust proof plate 15 in the dust collecting bin 14 and then discharged outwardly through the air outlet end of the fan. The air outlet end extends to the outside of the outer casing 9 to achieve air purification before discharge. In this way, the dust generated during the operation can be continuously captured and removed, further improving the dust proof function of the environmental protection sealing device, while ensuring the efficient and stable operation of the equipment and the health and safety of the operators.
