Description
Technical field
The present invention relates to Tea Processing technical field is and in particular to a kind of tea screening device.
Background technology
Existing is typically all to adopt artificial screening and mechanical grading in the process that Folium Camelliae sinensis are screened, and adopts wind mechanical grading more
Choosing, selecting crude drugs with winnower is weight using tender Folium Camelliae sinensis and the debris such as light impurity, sandstone, the difference of volume, shape and face size of keeping out the wind,
Respectively the debris such as the light yellow leaf in Folium Camelliae sinensis, sandstone are separated under certain wind-force effect.In existing tea-leaf wind selection device
Use feeding vibration table or thrust impeller in a large number, the dither of feeding vibration table is easy to damage the blade of Folium Camelliae sinensis, and thrust
Impeller is by rotation, Folium Camelliae sinensis stream to be thrown to selecting crude drugs with winnower area in feeding, and the stage of pan feeding and applying thrust easily makes Folium Camelliae sinensis piece
Impaired.
Publication No. 104384105B discloses a kind of tea screening device, includes sieve body, and sieve body is in circle
Cylindricality, it is horizontally disposed with vertically, the closed at both ends of sieve, and the bottom of sieve is provided with sieve sand net, and sieve sand side off the net be provided with
Sandstone holder, sandstone holder is in truncated cone-shaped, fixes with screen side walls above it, and screen side walls are along the perpendicular bisector running through axis
It is divided into two parts, wherein one side-lower is tangentially provided with inverted T-shape feed pipe, and the upper opening of feed pipe is charging
Mouthful, another opening is blast orifice, and screen side walls opposite side is set to screen cloth, and screen cloth is bottom-up to be divided into the steps increase of sieve aperture
Three screening areas, are provided with the container shrouding on corresponding screen cloth, the bottom of container is provided with the second sieve sand outside each screening area
Net.This device mainly carries out difference screening using screen cloth to Folium Camelliae sinensis, allows Folium Camelliae sinensis enter into correspondence by different regions on screen cloth
Screen cloth subregion in, but, said apparatus still employ wind-force as the power source of Folium Camelliae sinensis, and blast orifice is directed towards
Screen cloth, it is impossible to avoid the shock between Folium Camelliae sinensis and screen cloth, therefore, is sieved to Folium Camelliae sinensis using this device, and Folium Camelliae sinensis are because clash into
And it is impaired more serious.
Content of the invention
The purpose of the present invention is directed to the deficiencies in the prior art, provides one kind Folium Camelliae sinensis can be carried out with three-level screening and can prevent
Only Folium Camelliae sinensis are because clash into and a kind of impaired tea screening device.
For reaching above-mentioned purpose, the base case of the present invention is：A kind of tea screening device, including frame and fixed installation
Cylinder in frame, the top of described cylinder is provided with a feed hopper for conveying Folium Camelliae sinensis into cylinder, also solid in frame
Dingan County is upward through the bottom surface of cylinder, the output shaft of motor is set with and can produce in cylinder equipped with motor, the output shaft of motor
The cyclone blade of raw wind-force upwards, cyclone blade is located in cylinder and can rotate under the driving of motor in cylinder；Described
Diagonally disposed from top to bottom in cylinder have two grades of screen clothes, three-level screen cloth and an one-level screen cloth being only capable of through debris such as sandstones, and three
The sieve screen apertures of level screen cloth are more than the sieve screen apertures of two grades of screen clothes, the sieve screen apertures of two grades of screen clothes are more than the sieve screen apertures of one-level screen cloth, one-level
Inner barrel is separated into four screening spaces by screen cloth, two grades of screen clothes and three-level screen cloth, and cyclone blade is located under one-level screen cloth
Side；Three roads are provided with from bottom to top on the side wall of cylinder go out for the Folium Camelliae sinensis landing on one-level screen cloth, two grades of screen clothes or three-level screen cloth
The switching door of cylinder.
The principle of the present invention and effect：During use, Folium Camelliae sinensis to be sieved are put in cylinder by feed hopper, Folium Camelliae sinensis can be in advance
Reach on three-level screen cloth, start motor, Motor drive cyclone blade rotates, the cyclone blade of rotation produces upwards in cylinder
Wind-force.Folium Camelliae sinensis are subject to the dual function of gravity and wind-force, and one side Folium Camelliae sinensis are dispelled to be carried out to Folium Camelliae sinensis by three-level screen cloth simultaneously
So that the Folium Camelliae sinensis of small volume pass through on three-level screen cloth two grades of screen clothes of arrival, another aspect wind-force can prevent Folium Camelliae sinensis from piling up for filter
Agglomerating and then pockets of Folium Camelliae sinensis cannot be reached on two grades of screen clothes by the sieve screen apertures of three-level screen cloth.Reach on two grades of screen clothes
Folium Camelliae sinensis by two grades of screen clothes Folium Camelliae sinensis can be carried out with secondary filter under wind-force and action of gravity again, the Folium Camelliae sinensis of small volume again can be thoroughly
Cross the sieve screen apertures on two grades of screen clothes and reach on one-level screen cloth, meanwhile, the debris such as sandstone pass through the bottom that one-level screen cloth reaches cylinder,
This completes the screening of Folium Camelliae sinensis.
This programme compares currently existing scheme, can not only complete the disposable three level screen to Folium Camelliae sinensis, be additionally, since wind-force and subtract
The acceleration that little Folium Camelliae sinensis drop downwards, therefore reduces the shock of Folium Camelliae sinensis and one-level screen cloth, two grades of screen clothes or three-level screen cloth
Power is so that Folium Camelliae sinensis not only can be sized, and the blade of Folium Camelliae sinensis can keep integrity, prevent Folium Camelliae sinensis from suffering damage because of shock.
Further, it is additionally provided with heating wire between cyclone blade and screen cloth, heating wire is fixedly connected on cylinder.Heating wire exists
After energising, air can be heated it is also possible to heat to Folium Camelliae sinensis, such cyclone blade just can blow out hot blast, and then right
Pockets of Folium Camelliae sinensis are dried, and are more beneficial for pockets of Folium Camelliae sinensis and scatter.
Further, the side wall of cylinder is provided with glass window.Setting glass window is conducive to operator to cylinder
Interior tea screening situation Real Time Observation.
Further, the bottom of cylinder is provided with garbage mouth.Garbage mouth is set in cylinder body bottom, primarily to facilitating operator
Member clears up to debris such as sandstones.
