Closed conveying pipe

Abstract

The invention belongs to the field of mixing plant equipment, and discloses a closed conveying pipe. The closed conveying pipe comprises a conveying device used for conveying materials and a closed pipeline used for dust prevention of the materials, wherein the conveying device is positioned inside the closed pipeline, the conveying device comprises a conveying belt, a conveying roller and a rotating shaft, one end of the rotating shaft is connected with the conveying roller, the other end of the rotating shaft is connected with the closed pipeline, a tensioning adjuster is arranged at one endof the closed pipeline, and the tensioning adjuster is connected with the rotating shaft close to one end of the tensioning adjuster. According to the closed conveying pipe, the materials can be prevented from being in contact with an external environment, and effective environmental protection is achieved; and meanwhile, the tensioning degree of the conveying belt can be adjusted.

Description

technical field [0001] The invention belongs to the field of mixing station equipment, and in particular relates to a closed conveying pipe. Background technique [0002] The mixing station is a combined device used to centrally mix concrete, also known as the concrete prefabrication field. The degree of mechanization and automation is high, so the production efficiency is also high. Since the mixing station was put into use, it has been playing an important role in my country's construction industry. In addition to improving production efficiency, it also saves measurement time. [0003] However, in the existing mixing plant, the material is always in direct contact with the external environment during the output process. On the one hand, it pollutes the external environment to a certain extent; on the other hand, it also makes the material mixed with a large amount of impurities. Usually, the transmission pipeline is also equipped with a stable steel frame, and the steel...

Problems solved by technology

[0003] However, in the existing mixing plant, the material is always in direct contact with the external environment during the output process. On the one hand, it pollutes the external environment to a certain extent; on the other hand, it also makes the material mixed with a large amount of impurities.

Usually, the transmission pipeline is also equipped with a stable steel frame, and the steel frame is welded, and its welding accuracy will have a greater impact on the distribution accuracy of the conveyor belt; when the error is large, the staff will force the welding connection Finally, there will be a large assembly stress between the delivery pipe and the steel frame, which will eventually lead to cracking at the weld, which may cause unimaginable production accidents
