Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal devices, in particular to a primary screening device for metal impurities in raw tea. Background Art

[0002] Tea originated in China. Tea was first used as a sacrifice. However, it has been used as food since the late Spring and Autumn Period. It was developed into medicine in the middle of the Western Han Dynasty. It was not until the late Western Han Dynasty that it developed into a high-end beverage for the palace. It was not until the Western Jin Dynasty that it became popular among the people as an ordinary beverage. The earliest remains of artificial tea cultivation were found in the Tianluoshan site in Yuyao, Zhejiang, which has a history of more than 6,000 years. Tea is oblong or oval in shape and can be brewed directly with boiling water. It is divided into six categories according to the variety, production method and product appearance. It can be divided into spring tea, summer tea, autumn tea and winter tea according to the season. Reprocessed tea is formed by reprocessing various raw teas or refined teas, including flower tea, compressed tea, extracted tea, medicinal health tea, tea food, tea-containing beverages, etc.

[0003] At present, the existing utility model with publication number CN202026758U discloses a tea impurity removal device, including a frame, a box body is provided on the frame, a tea feed port is provided on the top of one end of the box body, and an air inlet is also provided on the side of the box body corresponding to the tea feed port, the air inlet is connected to the air outlet of the blower, and an impurity discharge port is provided on the lower side of the box body.

[0004] In the above scheme, during the process of removing impurities from tea leaves by the existing tea impurity removal device, since most of the metal impurities in the tea leaves are fine iron filings, rust or iron powder, etc., and the weight of the tea leaves is also very light, it is easy to remove the tea leaves and impurities together, resulting in waste of tea leaves; at the same time, the blower cannot effectively separate the mixed tea leaves and metal impurities, resulting in poor impurity removal effect; using air blowing to remove impurities consumes a lot of energy, resulting in high costs. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a raw tea metal impurity primary screening device, which can remove metal impurities in the raw tea by providing a primary screening component, thereby solving the problem that the prior art cannot effectively separate the raw tea and metal impurities, thereby improving the impurity removal effect, while saving energy consumption, saving production costs, and not wasting tea leaves.

[0006] The solution of the utility model to solve the technical problem is:

[0008] When it is necessary to perform a preliminary screening of impurities in the raw tea, the movable door is opened, and the raw tea is put into the feed bin, so that the raw tea passes through the guide component and is dispersed, so that the raw tea can effectively pass through the preliminary screening component, and the metal impurities in the raw tea are effectively adsorbed on the preliminary screening component, so that the raw tea and the metal impurities are separated, and the raw tea after passing through the preliminary screening component falls into the output channel below, so that the raw tea that has completed the preliminary screening can be transported to the next process through the output channel, and at the same time, by providing a vacuum tube, fine impurities such as dust that are diffused when the raw tea is put in can be extracted, thereby improving the screening efficiency of impurities in the raw tea.

[0009] By providing a primary screening component, metal impurities in raw tea can be removed, solving the problem that the prior art cannot effectively separate raw tea and metal impurities, thereby improving the impurity removal effect, while saving energy consumption, saving production costs, and not wasting tea leaves.

[0010] The utility model is further configured as follows: the guide assembly comprises a plurality of "V"-shaped guide plates fixed in the feed bin, and the tip of the "V"-shaped guide plate is configured to face upward.

[0011] Through the above technical solution, when raw tea is put in, it will contact with the tip of the "V"-shaped guide plate and then disperse, thereby facilitating the raw tea to effectively pass through the primary screening component.

[0014] The utility model is further configured as follows: the snap-on assembly includes a connecting plate, multiple magnetic bars on the same side are fixed to the same connecting plate, multiple snap-on blocks are fixed to one side of the connecting plate, a handle is fixed to the other side of the connecting plate, snap-on holes that cooperate with the snap-on blocks are formed on the side walls of the mounting frame, and a door panel is rotatably connected to each side of the body.

After the connecting block passes through the clamping hole, multiple clamping strips are squeezed and deformed. When the side wall of the connecting plate abuts against the end of the hollow tube, the clamping strip is not subjected to force and returns to its original shape, so that the connecting plate is clamped and fixed on the mounting frame, so that multiple magnetic bars can be clamped and fixed.
