Description

Technical Field

[0001] This utility model relates to the field of tea processing, and in particular to a tea iron removal device. Background Technology

[0002] During tea processing, raw tea leaves may contain magnetic impurities such as iron filings and screws. Traditional manual sorting is inefficient and prone to missing these impurities. While some existing technologies utilize magnetic rollers, the processing of materials absorbed by the rollers is mostly manual, requiring machine shutdowns and manual operation, thus impacting production efficiency. Furthermore, traditional magnetic systems typically only employ single-stage magnetic rollers, limiting their effectiveness in removing magnetic materials. Therefore, there is an urgent need for a device that improves automation, performs multi-stage iron removal, and facilitates the cleaning of magnetic impurities. Utility Model Content

A cylinder is provided on the outside of the iron removal chamber. The cylinder is connected to a first-stage push rod horizontally arranged inside the iron removal chamber. The first-stage push rod is vertically connected to the first movable plate on its right side. A first scraper that cooperates with the first magnetic roller is provided above the first movable plate. The second scraper is mounted on a second movable plate and moves vertically along the bottom of the iron removal chamber. The second movable plate is fixed to a second-stage push rod on its left side. The second-stage push rod is vertically mounted on the right side of the first movable plate. The rightmost ends of both the first scraper and the second scraper are provided with scraping tips.

[0009] The vertical distance between the first guide plate and the first magnetic roller is S1, the vertical distance between the first inclined guide plate and the second magnetic roller is also S1, the lateral distance between the scraping tip of the first scraper and the first magnetic roller is S2, and the lateral distance between the scraping tip of the second scraper and the second magnetic roller is also S2; after assembly, S1 < S2, and both the first magnetic roller and the second magnetic roller rotate clockwise.

[0010] Furthermore, the top center of the storage compartment is provided with a fixed support plate for installing the drive motor, and the left and right sides are provided with push-pull openings;

[0011] The storage compartment has a sliding door at its bottom opening, which is located above the first guide plate and the second guide plate.

[0012] Furthermore, the first magnetic roller and the second magnetic roller are either permanent magnet rollers or electromagnetic rollers, with electromagnetic rollers being preferred in practice.

[0013] Furthermore, a first baffle is provided on the left side of the first inclined guide tray. The first baffle is located on the bottom left side of the first magnetic roller. The first inclined guide tray is inclined to the lower right to prevent tea leaves from splashing outwards, so that the tea leaves can fall into the inclined guide tray effectively and be conveyed backwards.

[0014] Furthermore, a second baffle is provided on the left side of the second inclined guide plate. The second baffle is located on the bottom left side of the second magnetic roller. The second inclined guide plate is inclined to the lower right and the discharge end of the second inclined guide plate is directed towards the outside of the iron removal bin.

[0019] Furthermore, the internal structure of the storage compartment is made of 304 food-grade stainless steel.

[0020] Furthermore, the first and second inclined feed trays are also made of 304 food-grade stainless steel.

[0021] The beneficial effects of this utility model are as follows:

[0022] A tea leaf iron removal device has the following advantages over the existing manual iron removal process:

[0023] 1. Multi-stage iron removal effect can be achieved: Through the continuous magnetic adsorption design of the first and second magnetic rollers, the thoroughness of iron removal is improved. It should be noted that although this solution provides a two-stage iron removal effect, it can also be made into a three-stage, four-stage or other multi-stage setting in actual use. This design is stronger and better than the adsorption effect of a single magnetic roller.

[0024] 2. Automatic cleaning of adsorbed magnetic materials: By setting up a cylinder connected to two-stage push rods, each push rod is connected to a matching moving plate. Each moving plate is equipped with a scraper corresponding to the magnetic roller. Therefore, after the cylinder drives the scraper to move, in conjunction with the clockwise rotation of the magnetic roller, it can automatically scrape the material downward and remove the iron impurities adsorbed by the roller without stopping the machine or requiring manual operation.

[0025] 3. Uniform material distribution during feeding: By cooperating with the dispersing rod and the inclined guide plate, tea leaves are prevented from accumulating at the bottom of the storage bin. At the same time, the tea leaves can fall towards the right side of the first magnetic roller and fall with inertia. At this time, the magnetic iron material can be screened out and attracted by the magnetic roller, improving the magnetic separation efficiency. In addition, through structural optimization design, the spacing design of S1 < S2 ensures effective material feeding of tea leaves. At the same time, the scraper accurately contacts the roller, avoiding excessive material on the magnetic roller, which would affect the feeding. Attached Figure Description

[0039] When this utility model is used, there are several stages:

[0040] 1. Feeding stage: Tea leaves are fed into the storage compartment through the openings on the left and right sides at the top of the storage compartment. Initially, the bottom sliding door is not opened. When iron removal is required, the sliding door is opened and the drive motor is started. The drive motor drives the dispersing rod to rotate and disperse the tea leaves. With the cooperation of the first guide plate and the second guide plate, the tea leaves are guided to fall evenly onto the right side of the first magnetic roller.

[0041] 2. Iron removal process: The tea leaves continue to fall to the right due to inertia and are conveyed to the position of the first inclined guide plate. It should be noted that the first inclined guide plate is set to be long enough so that the subsequent tea leaves will tend to adhere to the first inclined guide plate and move inclined to the lower right to facilitate the second iron removal process. During this process, the first magnetic roller adsorbs iron impurities based on the magnetic attraction effect, thereby removing magnetic materials, including iron impurities, from the tea leaves. Then, the tea leaves slide along the first inclined guide plate to the second magnetic roller for a second iron removal process. The second iron removal process is the same as the first iron removal process.

[0042] 3. Impurity removal: When the first magnetic roller and the second magnetic roller have accumulated a certain amount of magnetic iron impurities, the cylinder is activated. The cylinder pushes the first-stage push rod and the second-stage push rod to move simultaneously, which drives the first scraper and the second scraper on the first moving plate and the second moving plate to move laterally. Combined with the effect of the clockwise rotation of the first magnetic roller and the second magnetic roller, the iron impurities adsorbed on the roller surface are automatically scraped off. The machine can be cleaned directly without stopping without manual intervention.

[0043] 4. Tea discharge: The iron-removed tea leaves are discharged through the second inclined guide plate, and iron impurities are collected. It should be noted that if this scheme is used to implement similar three-stage, four-stage, or multi-stage iron removal extension schemes, they will all be within the scope of protection of this scheme.

[0044] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
