Self-seal type pipe belt conveyor

Abstract

The invention relates to the technical field of conveying equipment, and provides a self-seal type pipe belt conveyor. According to the self-seal type pipe belt conveyor, a seal groove consistent to the conveying direction and a clamping connection part are included and arranged at the two ends of a belt correspondingly, wherein the clamping connection part is used for being embedded in the seal groove, and a seal structure is formed. The clamping connection part is matched with the seal groove in section shape. A groove expanding mechanism for expanding the seal groove is further arranged. Accordingly, one end of the belt is provided with the seal groove, and the other end is provided with the clamping connection part. When the belt is rounded, the clamping connection part is embedded inthe seal groove, then the seal structure is formed, the pipe belt conveyor achieves totally-closed feeding, and the problem that in the existing pipe belt machine feeding process, fine powder occurs or smells escape is solved. To guarantee smooth forming of the seal structure, the groove expanding mechanism for expanding the seal groove is further arranged so that the clamping connection part canbe smoothly embedded in or get out of the seal groove. The self-seal type pipe belt conveyor is simple in structure and obvious in effect, the performance of the pipe belt conveyor is greatly improved, and high economic value and environment value are achieved.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment, in particular to a self-sealing pipe-belt conveyor. Background technique [0002] The pipe belt conveyor has the characteristics of both pipeline conveying and belt conveying. It has the characteristics of large conveying inclination, small radius of curvature, small cross-sectional area of ​​the fuselage, curved conveying in three-dimensional space, and the conveying belt does not deviate, which is convenient for conveying line layout, maintenance and management. Etc. It is widely used in the long-distance transportation of various block or powder materials such as coal, ore, grain, cement, pulp and concrete. [0003] For example, in the patent of publication number: CN204250766U, the existing pipe belt conveyor gradually rolls up the conveyor belt through the circle forming transition device, and then makes the two ends of the belt form an overlapping structure through the circle f...

AI Technical Summary

Problems solved by technology

[0004] However, although the existing tube belt conveyor forms a closed round tube by overlapping the two ends of the belt, the overlapping portion is only in contact, and the seal between the two is not realized (that is, there is a gap in the overlapping portion). In addition, there is a large tension in the belt itself, which makes the gap between the overlapping parts of the ring frames easy to open, thus causing the fine powder or the smell of the material to escape from the overlapping parts, causing environmental pollution and material loss

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
