Problems solved by technology

my country's original tea fresh leaf winnowing machine adopts an open structure, and its winnowing indoor wind flow field is relatively ideal, but with the continuous improvement of environmental protection (dust removal) requirements, the original model can no longer meet the needs of the society
However, the winnowing quality of today's environment-friendly tea fresh leaf winnowing machines is generally not as good as that of open models. and the vortex above the tea outlet), should be one of the main reasons affecting the quality of its winnowing

Embodiment 1

[0026] Such as figure 1 and Figure 4 As shown, it is a schematic diagram of the planar structure of a kind of air separator for fresh tea leaves of the present invention and a schematic diagram of the structure of its micro-fan, including a rounded truncated housing 10, the upper surface of which is a feed inlet, The feeding port is connected with a conical sieve 20. The conical sieve 20 is a conical shape placed upright. The sides of the conical sieve 20 are all screens 201, and the mesh sizes of the screens 201 are set from small to large from top to bottom. The outer surface of 20 also has a left spiral descending ramp to slow down the descending process of fresh tea leaves on the cone sieve 20, so that the screening process of the cone sieve 20 is finer; Dust removal device: several outlets are evenly arranged at three different levels on the inner wall of the rounded frustum-shaped housing 10, and the number of outlets arranged at the same level is six, and the sizes of...

Embodiment 2

[0037] Such as Figure 2-3 As shown, it is a schematic diagram of the three-dimensional structure of Embodiment 2 of the present invention and a schematic diagram of the structure of the retractable corrugated shell 402. On the basis of Embodiment 1, the blowing device 40 can be configured to include a hard hemispherical shell 401 and a retractable corrugated shell 402. , the hard hemispherical shell 401 and the retractable corrugated shell 402 are connected to form a hollow cavity, and a fan is arranged in the hollow cavity, and the fan shown is electrically connected to the controller. It is airtightly connected with the air inlet of the shell. The fan injects wind into the shell through the air inlet on the rounded table-shaped shell 10, and the wind forms a stable wind field along the air guide rail. Through the retractable corrugated shell 402, the relative relative to the shell when the wind enters the rounded table shell can be adjusted. The angle of the side wall meet...

Abstract

The invention discloses a fresh tea leaf winnowing machine. The fresh tea leaf winnowing machine comprises an inverted-circular-platform-shaped shell. A feeding port is formed in the upper surface ofthe inverted-circular-platform-shaped shell. The feeding port is connected with a cone sieve, the cone sieve is in a uprightly-placed cone shape, and a screen is arranged on the side face of the conesieve. The part, below the feeding port, in the inverted-circular-platform-shaped shell is provided with a dust removal device. Six air inlets are evenly formed in the lower end of the shell. The airinlets are located at the same horizontal height and connected with an air blowing device. Air guiding guide rails are arranged at the positions of the air inlets, and a waste discharging port is formed in the lower end of the shell. According to a wind field device, a more stable wind field can be obtained in the work process, and different levels of tea leaves are screened out according to the aerodynamics features and the geometric features of the tea leaves of different qualities.

Description

technical field [0001] The invention relates to a wind separation machine for fresh tea leaves, which belongs to the field of wind separation mechanical equipment for fresh tea leaves. Background technique [0002] The principle of the fresh tea winnowing machine is to make use of the different aerodynamic characteristics of different tea leaves with different shapes and sizes. Under the action of wind, their drift distances are different. According to the drift position of the tea leaves, the quality of the tea leaves is distinguished. The key equipment in the fresh tea leaf processing equipment. [0003] The air-selected fresh tea leaves require that the tea leaves flowing out from the same tea outlet of the air-selection machine have its aerodynamic characteristic parameter-drift coefficient within the specified range, and if it exceeds this range, the separation is unclear. The main factors affecting the quality of tea winnowing are the wind speed distribution of the wi...
