Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal for tea processing, in particular to an impurity removal device for tea processing. Background Art

[0002] In the tea industry, if the tea is not sorted and classified properly, it will directly affect the grade and quality of the tea. In the process of tea processing, killing the green tea is an indispensable step. Before killing the green tea, the tea needs to be cleaned to prevent dust from adhering to the surface of the tea after killing the green tea. The existing tea cleaning machines generally have vibrating screen type or wind selection type cleaning;

[0003] The existing wind separation and impurity removal generally involves pouring the tea leaves into a horizontally placed mesh sieve cylinder, and then using a fan to blow away the lighter tea fragments and small branches in the tea leaves. However, the mesh sieve cylinder in this wind separation machine is generally a flat-lying type. After the tea leaves are poured into the mesh sieve cylinder, they will accumulate underneath it. When the mesh sieve cylinder rotates, the tea leaves may just slide down from the inside of the mesh sieve cylinder under the action of gravity instead of being turned over, resulting in an unsatisfactory impurity removal effect. In addition, when removing impurities from the tea leaves, it is necessary to continuously input tea leaves for wind separation, so that the new and old tea leaves in the mesh sieve cylinder are mixed together, which affects the quality of the tea leaves. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when the existing tea wind selection and impurity removal device is removing impurities from the tea leaves, the tea leaves slide along the inner wall of the mesh screen cylinder, resulting in failure to turn over in time, so that the impurity removal effect is not ideal, and the tea leaves after impurity removal cannot be taken out in time, resulting in the new and old tea leaves being mixed together, affecting the quality of the tea leaves.

[0005] To solve the above problems, the technical solution adopted by the utility model is a tea impurity removal device for processing tea, comprising a base, an outer frame fixed to the outer edge of the upper side of the base, a sealing cover rotatably connected to the top of the outer frame, a blower head fixed to the upper side of the base, and a wind selection net cylinder structure vertically arranged on the inner side of the outer frame above the base.

[0008] As a further solution of the utility model: the transmission structure includes a transmission pulley located between the mesh drum body and the base, and the transmission pulley is sleeved on the outside of the hair dryer head, a transmission motor is fixed on the upper side of the base next to the outer frame, a driving pulley is fixed to the output end of the transmission motor, and a transmission belt body is sleeved on the outside of the driving pulley and the transmission pulley. After the transmission motor is started, the mesh drum body can be driven to rotate through the driving pulley, the transmission belt body and the transmission pulley, and a long opening is opened on one side of the outer frame at the transmission belt body.

[0009] As a further solution of the utility model: a plurality of plug-in rods are fixed on the lower side of the net drum body, and plug-in interfaces are provided on the upper side of the transmission belt wheel at the plurality of plug-in rods, which can ensure that the transmission belt wheel drives the net drum body to rotate.

[0011] As a further solution of the utility model: the transmission motor is electrically connected to an external power source, and the air inlet is connected to an external air compression device.
