Dust treatment device for ventilating duct of winnowing machine

Abstract

The invention provides a dust treatment device for a ventilating duct of a winnowing machine. The device comprises a machine box, a grading mechanism is arranged at the bottom of the machine box, the two ends of the machine box communicate with a first shell and a second shell correspondingly, and a fan is fixed in the first shell. A first filtering mechanism used for filtering backflow air is arranged between the first shell and the second shell. The first filtering mechanism comprises a connecting shell arranged below the grading mechanism, the two ends of the connecting shell are rotationally connected with connecting pipes, and the other ends of the two connecting pipes communicate with the opposite faces of the first shell and the second shell correspondingly. Two alternately used frame bodies are slidably connected in the connecting shell. Wind energy resources blown out by the winnowing machine can be recycled, it is avoided that wind blown out by the winnowing machine carries dust and other impurities to directly enter and exit from air, and meanwhile the dust in the wind energy resources used in a backflow mode can be effectively filtered.

Description

Technical field[0001]The present invention relates to the field of dust treatment devices, and more particularly to a wind collector ventilation pipe dust treatment device.Background technique[0002]Tea belongs to the makar, the cama shrub or small trees, tender branches, leaf rolls, long circles or elliptical, tea can be used for drops of boiling water, divided into six major categories according to varieties and manufacturing methods and product shape. Tea drinks are known as * # * World's three major drinks * # *, tea containing tea, cholesterone, coffee base, inositol, folic acid, pantonic acid, etc., can enhance human health; tea leaves in picking then After stir -rying tea, it is necessary to sieve and dust removal treatment. The screening of tea leaves and dust removal is basically used to complete the style, but now the windpoint machine is used to adopt one end air and the other end Method, the dust present in the tea is directly discharged into the air, and the screening of...

AI Technical Summary

Problems solved by technology

[0003] The invention discloses a dust treatment device for the air duct of a winnowing machine, which solves the problem that the winnowing machine adopts the method of air inlet at one end and air outlet at the other end, so that the dust existing in tea leaves is directly discharged into the air, and cannot be sieved Effective treatment of the dust that comes out will have a certain impact on the working environment and the health of the staff
