Problems solved by technology

[0002] At present, in industrial production, materials are conveyed in a spiral manner. The most common one in the prior art is the screw auger conveyor. During use, it is found that the auger screw conveyor will squeeze the material, It is easier to form deposits inside the auger. This method has a greater impact on the quality of materials, especially the transportation of wet materials, especially when some wet materials cannot be squeezed, the auger transportation will seriously affect the quality of materials. Quality and the quality of subsequent products
[0003] Furthermore, if a large-capacity auger is used to ensure a large output, the auger usually has a larger diameter or a longer axial length, which occupies a larger area and is not easy to transport or store.

Embodiment 1

[0026] Refer to attached Figure 1~3 : A length-adjustable screw conveying device, comprising a fluid conveying pipe and a plurality of coaxially installed spiral air supply rings 4 which are set in the fluid conveying pipe, the fluid conveying pipe is divided into two parts, one part is a circular shell, The other part is an elastically stretchable telescopic connecting pipe 7. There are multiple sets of ring-shaped shells and telescopic connecting pipes 7, which are arranged in a staggered manner and are mutually blocked; The outside of the spiral air supply ring, the telescopic connecting pipe 7 is installed between the two spiral air supply rings 4, and the spiral air supply ring 4 is provided with an annular spiral guide cavity 403, and one side of the spiral guide cavity 403 is connected to the fluid delivery The annular housing of the pipe, the outer of the annular housing and the telescopic connecting pipe 7 are respectively connected with respective fluid input pipes,...

Embodiment 2

[0035] Refer to attached Figure 4 :

[0036] The diameters of the plurality of spiral air supply rings 4 gradually increase. The exterior of the multiple spiral air supply rings 4 is fitted with stepped tubes. The stepped tubes are double-layered tubes. An air supply chamber 3 is formed between the double-layered tubes. The air supply chamber 3 communicates with the spiral air supply ring 4 . A filter screen is provided at the air inlet end or the air outlet port of the spiral air supply ring 4 . Other settings and working process are the same as in Example 1.

Abstract

The invention discloses a spiral conveying device with an adjustable length, and belongs to the technical field of spiral material conveying. The spiral conveying device is characterized in that the spiral conveying device comprises a fluid conveying pipe and a plurality of coaxially-mounted spiral air supplying rings (4); the fluid conveying pipe is divided into two parts; a plurality of sets ofring shells and telescopic connecting pipes (7) are arranged separately and are connected in a stagger mode; the spiral air supplying rings (4) are internally provided with spiral flow guide cavities(403); one sides of the spiral flow guide cavities (403) communicate with the ring shells of the fluid conveying pipe; and air outlet holes are formed in the inner walls or an annular end wall of thespiral air supplying rings (4). The spiral air direction is formed by the spiral air supplying rings, and therefore the spiral propelling mode is formed. A material, especially a wet material can be conveyed with high quality without a blade. The nature and state of the material can be maximumly guaranteed during the conveying process. A structure is multisection splicing is adopted to the fluid conveying pipe. The telescopic mode facilitates storing and placing of a conveying machine with a large size and a large flow rate.

Description

technical field [0001] A length-adjustable screw conveying device belongs to the technical field of screw feeding. Background technique [0002] At present, in industrial production, the material is conveyed in a spiral manner. The most common one in the prior art is the screw auger conveyor. During use, it is found that the auger screw conveyor will squeeze the material. It is easier to form deposits inside the auger. This method has a greater impact on the quality of materials, especially the transportation of wet materials, especially when some wet materials cannot be squeezed, the auger transportation will seriously affect the quality of materials. Quality and the quality of subsequent products. [0003] Furthermore, if a large-capacity auger is used to ensure a larger output, the auger is usually provided with a larger diameter or a longer axial length, which occupies a larger area and is not convenient for handling or storage.
