Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen waste treatment, and particularly relates to a spiral shaft with quickly replaceable spiral blades. Background Art

[0002] As people's lives get better, there is more and more kitchen waste in daily life. The kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce bad odor. In order to process the kitchen waste, a large number of equipment will be used. Among them, high-pressure extruder is one of the most common equipment in the process of kitchen waste treatment. The use of high-pressure extruder can effectively achieve dry and wet separation of kitchen waste;

[0003] The high-pressure extruder for kitchen waste treatment is generally composed of a frame, a feeding structure, a discharging structure and the like. The feeding structure is generally a spiral blade, which not only drives the kitchen waste to be fed, but also realizes the preliminary extrusion of the kitchen waste. It is one of the important components of the high-pressure extruder.

[0004] However, during use, the spiral blades of the existing high-pressure extruders for kitchen waste treatment are easily worn, and the spiral blades and the shaft are generally integrated, so that after the spiral blades are worn, the entire shaft needs to be replaced as a whole, and replacing the shaft will cause production suspension and thus affect production efficiency.

[0005] To this end, we provide a spiral shaft with quickly replaceable spiral blades to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a spiral shaft with quickly replaceable spiral blades, wherein a conveying section shaft tube and conveying section blades are mounted on a main shaft through a first conveying section positioning sleeve and a second conveying section positioning sleeve in a compression section shaft sleeve, and the compression section shaft tube is mounted on the main shaft through a compression section cone sleeve and a compression section positioning sleeve, thereby mounting the first conveying section blade and the second conveying section blade on the main shaft, thus solving the existing problem of inconvenience in replacing blades.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] The utility model is a spiral shaft capable of quickly changing spiral blades, comprising a main shaft, one side of the outer wall of the main shaft is sleeved with a conveying section sleeve, and the other side of the outer wall of the main shaft is sleeved with a compression section sleeve, and is characterized in that:
