Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a sealed, environmentally friendly, reversible bunker belt conveyor. Background Art

[0002] In the field of raw material transportation in coal, chemical, electric power and other industries, in order to improve the utilization rate of silos, it is necessary to carry out multi-point continuous and uniform material distribution in silos. At present, its material distribution work can generally be implemented by ordinary belt conveyors with plow-type dischargers, mobile discharge trolleys, reversible silo belt conveyors, scraper conveyors and other equipment.

[0003] As a continuous conveying equipment for silo top batching, reversible silo belt conveyor has the characteristics of flexible operation and suitability for various bulk materials. It has been widely used in coal, chemical, power and other industries. However, reversible silo belt conveyor is in open working mode when it is working. When conveying fine powder dry materials such as coal and ore, a large height difference of the drop point, pressure difference inside and outside the silo and many other factors will cause a large amount of dust to spread to the surrounding during unloading, resulting in extremely harsh environment on the top of the silo, with a lot of dust, which will seriously affect the physical and mental health and work attitude of on-site personnel.

[0004] Existing, some reversible bin-equipped belt conveyors have added a sealing structure to reduce dust pollution. For example, the utility model patent with authorization announcement number CN212607526U discloses an environmentally friendly reversible bin-equipped mobile belt conveyor, which adds an upper dust prevention device and a conveyor belt dust prevention device to the reversible bin-equipped belt conveyor, wherein the upper dust prevention device includes a sealing tape arranged on both sides of the material guide trough bracket along the material conveying direction, a redirecting roller group and a locking device arranged on the outer side of the two ends of the conveyor frame, a roller is fixedly installed on the material guide trough bracket, one end of the sealing tape is wrapped around the roller, and the redirecting roller group and the locking device are used to tension the sealing tape.

[0005] The sealing tape in the upper dustproof device of this structure is located above the guide chute bracket. When in use, it needs to cooperate with the top sealing baffle to complete the sealing of the top of the conveyor belt. After long-term use, it was found that the sealing tape of this structure has the disadvantage of poor sealing on both sides of the edges due to frequent friction between its two sides and the reversible bin belt conveyor. At the same time, since the sealing tape is relatively long, after long-term use, it is affected by its own weight and material fatigue, causing the middle of the sealing tape to sink, causing the two sides of the sealing tape to move inward, which also affects the sealing effect of the edges on both sides. This results in that after long-term use, the sealing tape cannot reduce dust pollution on the materials on the conveyor belt, and there is a disadvantage of dust leakage, which affects normal use. At the same time, mutual friction also reduces the service life of the sealing tape, which needs to be replaced in time, reducing production efficiency and increasing production costs and maintenance difficulties.
