Abstract

The utility model relates to screening equipment applied in a refining process of keemun black tea. The screening equipment comprises a feed port, a screening bed and a plurality of inclined screening surface layers, wherein the plurality of inclined screening surface layers are formed in the screening bed from top to bottom in sequence; and a discharge port is correspondingly formed in each screening surface layer. The screening equipment applied in the refining process of the keemun black tea is characterized by further comprising four rotatable rotating shafts; at least one of the four rotatable rotating shafts serves as a driving shaft which is driven by a motor; a crank shaft is connected to the upper end of each rotating shaft; one end of each crank shaft is hinged with the bottom of the screening bed; the crank shafts are connected in the same direction; and the whole screening bed is supported by the four crank shafts and can realize the plane rotary movement along with the crank shaft. According to the screening equipment applied in the refining process of the keemun black tea, the tea can be sorted by utilizing the plurality of screening surface layers, so that the screening efficiency is high, the working strength of workers is greatly reduced, the loss of impurities is also greatly improved, and the screened tea is uniform in thickness.

Description

The screening plant that uses in a kind of Keemun black tea subtractive process

Technical field

The utility model relates to a kind of screening plant, relates in particular to the screening plant that uses in a kind of Keemun black tea subtractive process.

Background technology

Tealeaves fine finishining is a very numerous and diverse job, each tealeaves monomer generally will be through the quality of tens roads even more operation guarantee final finished, there is very important operation to be the screening operation in the tealeaves fine finishining process, can make the tea quality of producing comparatively even by screening, the material sieving technology that the most generally adopts in the Tea Processing industry at present often only adopts a standard to screen tealeaves, so just caused that still to occur the tea raw material thickness after screening inhomogeneous, the situation that impurity is more, so that impuriting rate descends greatly, also increased difficulty for the processing of later stage operation.

The utility model content

The purpose of this utility model is to provide a kind of screening plant of using in the Keemun black tea subtractive process of screening effect of guaranteeing.

The purpose of this utility model is achieved through the following technical solutions; The screening plant that uses in a kind of Keemun black tea subtractive process, comprise that feeding mouth, sifting bed, sifting bed inside are disposed with the compass screen surface that multilayer tilts from top to bottom, every one deck compass screen surface is provided with corresponding with it discharging opening, also comprise four rotatable turning cylinders, have at least one to be driving shaft in the described turning cylinder, driving shaft is by motor-driven, the upper end of each turning cylinder is connected with bent axle, one end of bent axle and the bottom of sifting bed are hinged, the connection orientation of described bent axle is consistent, whole sifting bed is supported by four bent axles, and can do the plane rotation motion with bent axle.

Further, the inner compass screen surface spaced set that arranges of described sifting bed.

Further, the inner compass screen surface that arranges of described sifting bed is four layers.

Further, two on driving shaft is arranged in the described turning cylinder.

Further, the motor of described driving driving shaft is by the motor automatic controlling system.

The advantage of the screening plant that uses in the Keemun black tea subtractive process that the utility model provides is: utilize multi-deck screen to face tealeaves and sort, screening efficiency is high, greatly reduce workman's labour intensity, simultaneously impuriting rate is greatly improved, the tealeaves even thickness of sieving out.

Description of drawings

Fig. 1 is the structural representation of the screening plant that uses in the utility model Keemun black tea subtractive process.

Fig. 2 is that the utility model is assemblied in the overall structure schematic diagram on the production line.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

See also Fig. 1 and Fig. 2, wherein Fig. 1 is the structural representation of the screening plant that uses in the utility model Keemun black tea subtractive process, and Fig. 2 is that the utility model is assemblied in the overall structure schematic diagram on the production line.

As shown in Figure 1, the screening plant that uses in a kind of Keemun black tea subtractive process of the utility model embodiment comprises feeding mouth 81, sifting bed 82, sifting bed 82 inside from top to bottom successively the spacing setting be provided with the compass screen surface of four inclinations, every one deck compass screen surface is provided with corresponding with it discharging opening 83, also comprise four rotatable turning cylinders 84, there are two to be driving shaft in the described turning cylinder 84, driving shaft is by motor-driven, motor is by the motor automatic controlling system, the upper end of each turning cylinder 84 is connected with bent axle 85, one end of bent axle 85 and the bottom of sifting bed 82 are hinged, the connection orientation of described bent axle 85 is consistent, whole sifting bed 82 is supported by four bent axles 85, and can do the plane rotation motion with bent axle 85.

In use, tea leaf is crossed on the compass screen surface that feeding mouth 81 falls into the superiors, under the driving effect of motor, turning cylinder 84 rotates, and band dynamic crankshaft 85 rotates, the bent axle 85 that rotates drives whole sifting bed 82 and does the plane rotation motion, thereby the tealeaves of different sizes is fallen in screening process on the different compass screen surfaces successively, because compass screen surface tilts the process effect of vibration, tealeaves through screening is discharged from discharging opening 83, by transfer tube 2 tealeaves is transferred to next procedure again and processes.

Fig. 2 is that the utility model is assemblied in the overall structure schematic diagram on the production line, this production line comprises drying plant 1, even heaping equipment 5, equipment for removing ferric ion 6, screening plant 8 and weighing-appliance 7, be connected by transfer tube 2 or transport tape 3 between equipment and the equipment, in process of production, tealeaves is dried by drying plant 1 first, by transfer tube 2 it is transferred on the transport tape 3 after the oven dry, transport tape 3 is delivered to pan feeding hole interior 4 with tea leaf conveying, by transfer tube 2 it is transferred in the even heaping equipment 5 again, through being transported on the equipment for removing ferric ion 6 by transport tape 3 again after the even heaping equipment 5 even heaps, through after the deironing, tea leaf is crossed transfer tube 2 and is transferred on the screening plant 8 and sieves, rear being transferred on the weighing-appliance 7 by transfer tube 2 of screening weighed, and packs afterwards warehouse-in.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
