Novel Roots blower material conveying device

Abstract

The invention aims to provide a novel Roots blower material conveying device comprising a material storage bin, a spiral propeller, a receiving hopper and a Roots blower. A material outlet in the lower portion of the material storage bin communicates with a feeding port of the spiral propeller; a rotating shaft of the spiral propeller is connected with a rotating shaft of a motor to form a material propelling structure; a discharging port of the spiral propeller communicates with a rotary valve through a pipeline, wherein the rotary valve is mounted at an upper opening of the receiving hopper and used for material adding; an air inlet pipeline on the lower portion of the receiving hopper communicates with an air outlet of the Roots blower, and a pipeline, with an inclined-surface-shaped outlet, on the lower portion of the receiving hopper communicates with a positive pressure conveying pipeline; and the bottoms of the air inlet pipeline, the pipeline with the inclined-surface-shaped outlet and the positive pressure conveying pipeline are on the same plane. The novel Roots blower material conveying device is simple in structure, novel, unique and convenient to mount and use, material reverse injection caused by pipeline blockage is effectively solved, the pressure loss of the positive pressure pipeline is reduced, energy consumption is reduced, the working efficiency is high, and the economic and social benefits are remarkable.

Description

technical field [0001] The invention relates to machinery, in particular to a novel Roots blower conveying material device. Background technique [0002] In industrial production, material conveying is a common occurrence, and there are many kinds of conveying devices, but at present, the conveying of high-concentration materials is often carried by Roots blower, which is high-concentration positive pressure conveying, and the material is conveyed in The positive pressure pipe at the outlet of the fan enters, and there are many phenomena that the material cannot enter the pipe due to the air pressure inside the pipe. Many users have headaches and troubles. The material in the pipeline is affected by the reverse spraying, which affects the normal transportation, the production efficiency is low, and its use is unsatisfactory. Therefore, the improvement and innovation of the Roots fan conveying material equipment is imperative. Contents of the invention [0003] In view of ...
