Abstract

The utility model discloses a rotational-wind generator. The rotational-wind generator is characterized in that a core pipe is arranged inside a pipe shell, spiral wind guide blades are arranged on the core pipe, a wind inlet is arranged at one end of the pipe shell, and a wind outlet is arranged at the other end of the pipe shell; a tapered body is arranged on the core pipe at the wind inlet end to reduce wind resistance. When the rotational-wind generator is in use, the front end of the rotational-wind generator is connected with a wind outlet of a three-blade impulse roots blower, and wind flow of the three-blade impulse roots blower passes the rotational-wind generator to become a hollow tornado which enters a wind conveyor from the wind outlet of the rotational-wind generator. During feeding of the wind conveyor, materials are wrapped in a central layer of a pipeline to be pushed forwards under the action of rotational wind, so that blocking caused by mutual collision is avoided; the materials are centralized in the central layer of the pipeline, so that contact and friction between the materials and the pipeline are avoided, and abrasion of the pipeline is reduced.

Description

Rotary wind maker

Technical field

The utility model relates to wind-force conveying technology.

Background technology:

In various pneumatic conveyors, adopt the moving Roots blower of three veins as power at present.Because the distinguished and admirable of the moving Roots blower of three veins be that straight speed is distinguished and admirable, easily there is the problem of two aspects: the one, in course of conveying, material is in different size, because gas-solid ratio causes more greatly running velocity different, thereby mutual collision impact and stopping up; The 2nd, because contacting and rubbing all can appear in mode of movement material and tube wall, the serious wear of material to pipeline.

Utility model content

For addressing the above problem, the utility model design is a kind of can be by the distinguished and admirable maker that becomes rotary wind of the moving Roots blower of three veins.

For achieving the above object, the technical scheme that the utility model is taked is:

A maker, is characterized in that, it is to be provided with core pipe in one section of shell, and core pipe is provided with helical wind-guiding blade, and one end of shell is that ventilation inlet, the other end are air outlet; The core pipe of ventilation inlet end is made as cone, to reduce windage.

During use, the front end of rotary wind maker is connected with the air outlet of the moving Roots blower of three veins, three veins move the distinguished and admirable through rotary wind maker of Roots blower, become the wind spout of hollow form, by rotary wind maker air outlet, enter pneumatic conveyor.

The utility model has the advantages that: when pneumatic conveyor feeding, due to rotation wind action, material is just enclosed in pipeline center's layer and is promoting to move ahead.There will not be so mutual collision impact and stop up, and material concentrates on the central core of pipeline, there will not be pipeline contact and friction, reduce the wearing and tearing to pipeline.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the utility model embodiment.

In figure: 1-core pipe, 2-shell, 3-cone, 4-helical wind-guiding blade.

The specific embodiment:

Rotary wind maker embodiment as shown in Figure 1, it is to be provided with core pipe 12 li of one section of shells, and core pipe 1 is provided with three circle helical wind-guiding blades 4, and one end of shell 2 is that ventilation inlet, the other end are air outlet; The core pipe of ventilation inlet end is made as cone 3, to reduce windage.

Claims

1. a rotary wind maker, is characterized in that, it is to be provided with core pipe in one section of shell, and core pipe is provided with helical wind-guiding blade, and one end of shell is that ventilation inlet, the other end are air outlet; The core pipe of ventilation inlet end is made as cone, to reduce windage.
