Description

Technical Field

[0001] The invention relates to a bulk cement conveying belt dust control material guide trough and a dust control conveying system. Background Art

[0002] Bulk cement is very likely to generate dust during production, transportation, and loading and unloading, which not only pollutes the environment, but may also affect the health of surrounding operators. Especially during the cement transportation stage, dust is scattered along with the belt conveyor, which not only affects the normal operation of the equipment, but also increases maintenance costs and the difficulty of dust control. In order to solve the dust problem during the transportation of bulk cement, many factories have begun to introduce dust control guide troughs and dust control conveying systems in the belt conveyor system. These systems can effectively reduce dust diffusion, optimize the working environment, and improve the cleanliness and stability of the transportation process.

[0003] The patent with announcement number CN116605588A discloses a dust control guide trough and a dust control conveying system for a bulk cement conveying belt, which can automatically adjust the position of the sealing strip according to the deformation of the belt, and can be compatible with the situation where the matching gap increases due to the wear of the sealing strip and the deformation of the conveying belt itself, and effectively ensure the sealing performance of the dust control guide trough. However, the existing dust control guide trough and the dust control conveying system for bulk cement conveying belts still have certain defects when in use. The bulk cement thereon is easily accumulated and blocked at the feed hopper, which makes the guide trough for the bulk cement guide rate slow. At the same time, the cement in the guide trough will fall directly onto the conveyor belt and generate a large amount of dust, which is not conducive to the normal transportation of bulk cement.
