Threshing and pneumatic separating discharging device of screen with pneumatic balancing function and for pneumatic separating

Abstract

The invention belongs to the field of tobacco industry and relates to threshing and re-drying machinery and equipment, in particular to a threshing and pneumatic separating discharging device of screen with a pneumatic balancing function and for pneumatic separating. The threshing and pneumatic separating discharging device comprises a device body, an exhaust barrel penetratingly and transversely arranged in the device body, and a feeding flat pipe connected at the upper end of the device body, the screen wraps the exhaust barrel to be arranged in the device body, a star-like discharging roller is arranged at the lower bottom end of the device body, a plurality of meshes are distributed in the screen, and number of the meshes is decreased progressively from the middle to two ends of the screen. The threshing and pneumatic separating discharging device is reasonable in structure, simple in mechanism, easy to manufacture and low in cost. A novel discharging device screen is creatively designed, so that air speed and air pressure in the inner exhaust barrel are uniform, blockage of the meshes at two ends of the screen is eliminated, the old problem of material accumulation on two sides of a material flat pipe above a threshing and re-drying tangential discharging device is solved, materials fall uniformly, pneumatic separating efficiency is improved, and threshing and re-drying processes are improved effectively.

Description

technical field [0001] The invention relates to a leaf threshing and redrying mechanical equipment, which belongs to the field of the tobacco industry, in particular to a leaf threshing air separation and blanking device with a wind balance screen for air separation. Background technique [0002] The tangential feeder has the advantages of high material distribution efficiency, large processing air volume, and an unimpeded wind system. It is the main device of the pneumatic conveying equipment in the leaf threshing and redrying equipment. However, due to the unreasonable design of the body structure and the high wind speed of the inner exhaust tube, there are often the following problems during use: a. The inner exhaust tube has a high wind speed and a large negative pressure, and a large number of blades will be adsorbed at both ends of the screen. , resulting in blockage of the mesh at both ends of the screen; b. Due to the blockage of the mesh at both ends of the screen, ...

AI Technical Summary

Problems solved by technology

[0003] The present invention intends to address the above problems, and provides a leaf-threshing and air-separating blanking device with a wind-balanced air-separating screen, which solves the old problem of material accumulation on both sides of the flat tube above the material flat tube for threshing and re-roasting , so that the material falls evenly, improves the air distribution efficiency, and effectively improves the processing technology of threshing and redrying
