Description

Winnowing device for tea production and processing

Technical Field

The invention relates to the field of tea processing equipment, in particular to a winnowing device for tea production and processing.

Background

The winnowing machine is an important device in tea processing, and the principle of the tea winnowing machine is that non-tea impurities such as light yellow floating pieces, sand and stones in tea are separated out under the action of certain wind power by utilizing the characteristics that the tea with different grades has different weights and different drift distances under the action of wind power, so that the aim of purifying the tea is achieved, and meanwhile, the tea is classified according to the particle size.

When current air classification equipment carries out the selection by winnowing to piling up of tealeaves in the storage vat can lead to having the phenomenon of adhesion or even bold agglomeration in the tealeaves, leads to tealeaves weight to increase, can lead to the miselection, has sneaked into the tealeaves of other grades in the tealeaves of certain grade in the storage vat promptly to reduce tealeaves quality.

Disclosure of Invention

The invention aims to provide a winnowing device for tea production and processing, which can solve the problem of mistaken selection caused by the increase of the weight of tea due to the phenomenon of adhesion and even agglomeration of large blocks in the tea in the conventional winnowing equipment.

In order to achieve the purpose, the invention adopts the following technical scheme:

a winnowing device for tea production and processing comprises a support frame and an inclined support column arranged on the support frame, wherein the support column is hollow, a driving mechanism for driving the support column to rotate is arranged on the support frame, an included angle is formed between the rotation axis of the support column and the axis of the support column, a storage barrel is fixed at the top of the support column, a plurality of feeding holes are formed in the storage barrel, a plurality of dust removal pipelines which are in one-to-one correspondence with the feeding holes are arranged below the storage barrel, the top of each dust removal pipeline is communicated with the corresponding feeding hole, the bottom of each dust removal pipeline is communicated with the support column; the bottom of the supporting column is provided with an air blowing opening which is communicated with an air blowing mechanism used for blowing air into the supporting column.

The principle of the scheme is as follows:

the support frame is used for playing the supporting role to the support column, and actuating mechanism is used for driving the support column rotatory, and the support column is rotatory to be used for driving the fixed storage vat motion in support column top, and the motion form of storage vat produces the rotation when being circular motion around the support column axis of rotation to make tealeaves in the storage vat fall from the feed port of storage vat bottom, the bold tealeaves cluster of agglomerating simultaneously remains in the storage vat because can not get into the feed port. Because the axis of rotation has the contained angle rather than self axis when the support column is rotatory, the storage vat motion can also make tealeaves have in the storage vat along the motion on the storage vat cross section, tealeaves rolls in the storage vat, can avoid the tealeaves in the storage vat to plug up the feed port.

The tea leaves entering the feeding hole enter the inclined dust removal pipeline, the tea leaves roll downwards in the dust removal pipeline, and powder in the tea leaves leaks out of the dust removal hole in the bottom of the dust removal pipeline, so that the dust in the tea leaves is removed.

The tea leaves with dust removed enter the supporting columns, the tea leaves automatically fall under the action of gravity, the air blowing mechanism blows air into the supporting columns through the air blowing openings to generate upward air flow, the upward air flow and the downward tea leaves generate convection, and therefore the tea leaves are fried and impacted, and the tea leaves which are adhered are separated.

This scheme of adoption can reach following technological effect:

can stay the bold tealeaves group of caking in the tealeaves in the storage vat through the storage vat motion, select the tealeaves that accords with the loose form of requirement, nevertheless have the tealeaves of adhesion together in the tealeaves of loose form, through tealeaves at the support column internal motion, thereby the air current produces the convection current with tealeaves and separates the tealeaves of adhesion to thereby solved current air separator because there is the adhesion in the tealeaves and the phenomenon of bold group leads to the problem that the tealeaves weight increases and leads to the miselection.

Further, the support column comprises an outer barrel and an inner barrel, an air flow channel is formed between the outer barrel and the inner barrel, a plurality of air holes are formed in the inner barrel, and the air blowing openings are formed in the outer barrel. The tea leaves move downwards in the inner barrel, the air flow moves upwards in the air flow channel, the air flow can stir the tea leaves in the inner barrel through the air holes in the inner barrel, meanwhile, according to the Bernoulli effect, the air flow in the air flow channel can take away residual dust in the tea leaves, and the dust in the tea leaves is further removed.

Furthermore, be fixed with two on the support frame and support the cover, support the cover inboard and be hemispherical block chamber, be fixed with two hemispherical block portions on the support column, two block portions block respectively in two block intracavity, block chamber and block portion cooperation. Through the cooperation of two block chambeies and block portion, can play the supporting role to the support column, can also satisfy the rotatory requirement of support column simultaneously.

Furthermore, a fixed sleeve is fixed on the support frame, a discharge pipe is connected in the fixed sleeve in a rotating mode, the top of the discharge pipe is communicated with the bottom of the inner cylinder of the support rod through an inclined pipe, a rotating sleeve is arranged on the discharge pipe in a fixed mode, the driving mechanism comprises a motor fixed to the bottom of the support frame, and the motor and the discharge pipe are in belt transmission. The discharging pipe is driven to rotate by the motor, and the discharging pipe drives the supporting column to rotate through the inclined pipe.

Furthermore, a dust collecting cylinder is fixed below the storage barrel, and the dust removing pipes are all positioned in the dust collecting cylinder. The dust collecting cylinder can collect dust leaked from the dust collecting pipe.

Further, the top of the airflow channel is communicated with the dust collecting barrel. The dust brought out by the airflow channel can enter the dust collecting cylinder to be collected.

Furthermore, the top of the dust collecting barrel is communicated with a dust removing bag. The dust in the dust collecting barrel can be removed by the dust removing bag, and the dust in the dust collecting barrel can be blown up by the airflow in the airflow channel, so that the dust can be better absorbed by the dust removing bag.

Further, the feed port is located storage vat bottom edge. Because the storage vat is in the tilt state all the time during the motion, set up the feed port in storage vat bottom border, tealeaves in the storage vat gets into the feed port more easily.

Further, the air blowing mechanism comprises an air pump fixed at the bottom of the support column, and the air outlet end of the air pump is communicated with an air blowing port on the support column. The air flow generated by the air pump is blown into the air blowing opening, so that the upward air flow can be generated in the air flow channel, and the structure is simple.
