Description

TECHNICAL FIELD

[0001] The utility model relates to tea impurity removal technical field, especially tea impurity electrostatic adsorption removal equipment. BACKGROUND

[0002] In the tea processing industry, the purity of tea plays a crucial role in the quality and market value of tea. During the picking, transportation and preliminary processing of tea, various impurities such as hair, fiber, fluff and ash powder will inevitably be mixed in. These impurities not only affect the appearance of tea, but also change the taste and flavor of tea to some extent, reducing the satisfaction of consumers. Therefore, efficient and accurate removal of impurities in tea has become an indispensable part of the tea processing process. With the continuous development of science and technology, tea impurity electrostatic adsorption removal equipment has emerged as the times require. It uses the principle of electrostatic adsorption to provide a new solution for tea impurity removal, greatly improving the efficiency and quality of tea impurity removal.

[0003] The existing tea impurity removal technology mainly adopts traditional screening, air selection and other mechanical methods. Screening is to separate tea and impurities according to the size difference of particles through different mesh screens. Air selection is to separate impurities with lighter weight from tea by using air force. Screening technology is mainly based on the size difference of tea and impurities, and separates them through different mesh screens. Air selection technology separates impurities with lighter weight from tea by using air force. These traditional methods can remove some impurities to some extent, but for some small, light and not easy to pass through physical screening or air separation impurities such as hair and fluff, the effect is not ideal.

[0004] However, these traditional mechanical impurity removal methods have a significant problem, that is, it is difficult to effectively remove extremely small and strongly adhered impurities such as hair and fluff from tea. These impurities are small in size and light in weight, and can easily pass through the screen with tea during screening, and are difficult to be completely separated by air force during air selection, which cannot fully guarantee the purity of tea, which not only affects the appearance quality of tea, but also reduces the trust of consumers to the product, and further affects the market competitiveness of tea products. The new type of tea impurity electrostatic adsorption removal equipment and its related improved structure are developed to solve this key problem, and the tea impurity electrostatic adsorption removal equipment is proposed to solve the above problems.

DETAILED DESCRIPTION​

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] With reference to Figure 1 Figure 3 An embodiment provided by the utility model: tea impurity electrostatic adsorption and removal equipment, including support frame 1, support frame 1 inside is provided with conveying belt 2, conveying belt 2 is used for conveying tea from the entrance to the removal area, guarantees the fluency and stability of tea in the processing process, avoids the influence of excessive vibration on tea quality, and support frame 1 one side is fixedly connected with control assembly 3, control assembly 3 is responsible for the power supply of the whole equipment, the control of operation panel and the cooperative work between each component, support frame 1 one side is fixedly connected with tea collecting hopper 4, is used for collecting tea after being treated by equipment, ensures the smooth separation and storage of tea, and support frame 1 top is provided with electrostatic removal component, and electrostatic removal component is used for removing the fine impurities mixed in tea;

[0033] The electrostatic removal component includes fixed frame 5, the fixed frame 5 is rotatably connected with electrostatic adsorption roller 6 in the inside, the electrostatic adsorption roller 6 generates static electricity by electric current when working, so that the fine impurities in tea are adsorbed to the roller surface, the fixed frame 5 inner wall is fixedly connected with connecting block 7, the connecting block 7 is internally provided with limiting groove 11, the connecting block 7 is fixedly connected with scraper 8 in the inside, the scraper 8 is of rubber material, the scraper 8 is of rubber material, and its main role is to scrape off the impurities attached to the electrostatic adsorption roller 6 regularly, to prevent the impurities from accumulating and affecting the adsorption effect, the connecting block 7 is fixedly connected with impurity collecting hopper 9 in the inside, the scraper 8 and impurity collecting hopper 9 outer wall are in contact, the impurity collecting hopper 9 side wall is provided with dismounting assembly, the dismounting assembly is used for facilitating the operator to quickly clean and dismount impurity collecting hopper 9, and the impurity collecting hopper 9 is used for collecting the impurities scraped off by the scraper 8.

[0034] ​Specifically, when the tea impurity electrostatic adsorption removal equipment is running, the small particle impurities adsorbed on the surface of the electrostatic adsorption roller 6 accumulate and affect the adsorption effect and stable operation of the equipment, or cause the impurities to be mixed into the tea again. The operator places the tea on the surface of the conveying belt 2, which slowly and evenly conveys the tea, ensuring that the tea is not damaged during transportation and can smoothly enter the subsequent cleaning link. In order to effectively remove the impurities inside the tea, the equipment is processed by the electrostatic adsorption roller 6. The electrostatic adsorption roller 6 generates an electrostatic field to attract small impurities in the tea, such as dust, fine particles or other debris, so that they adhere to the roller surface, achieving the purpose of removing impurities. In the process of adsorbing impurities by the electrostatic adsorption roller 6, the scraper 8 plays a crucial role. The scraper 8 rubs against the surface of the electrostatic adsorption roller 6, using friction to scrape off the impurities adhering to the roller surface. The scraper 8 ensures that the impurities are completely removed and prevent them from being mixed into the tea again. The scraped impurities fall into the impurity collection hopper 9 under the guidance of the scraper 8. The impurity collection hopper 9 effectively collects these impurities, preventing them from affecting the purity of the tea. In this process, the tea treated by the electrostatic adsorption roller 6 continues to move slowly under the action of the conveying belt 2 and eventually falls into the tea collection hopper 4 for collection.

[0035] Referring to Figure 4 and Figure 5 , the disassembly assembly includes a fixed rod 10 and a connecting column 12. The fixed rod 10 is fixedly connected to the inner wall of the impurity collection hopper 9, ensuring that the impurity collection hopper 9 remains stable during use. The connecting column 12 is fixedly connected to the inside of the fixed rod 10. The outer wall of the connecting column 12 is slidingly connected with a sliding ring 13. The inside of the sliding ring 13 is rotatably connected with a transmission rod 14. The rotation of the transmission rod 14 makes the entire disassembly process more flexible and efficient, allowing smooth completion of the disassembly and installation of the collection hopper. One side of the transmission rod 14 is rotatably connected with a transmission plate 15. One side of the transmission plate 15 is fixedly connected with a clamping block 16. The clamping block 16 is matched with the limiting groove 11. The clamping block 16 ensures that the entire impurity collection hopper 9 does not shift or loosen during disassembly and installation by matching with the limiting groove 11.

[0036] Specifically, when the impurity collection tank is full and needs to be cleaned, or the equipment needs to be maintained, the impurity collection condition needs to be checked, and the collection tank needs to be replaced or repaired, the operator pulls down the impurity collection bucket 9 directly, and under the action of the pulling force, the clamping block 16 slides in the limiting groove 11. The sliding of the clamping block 16 drives the offset movement of the transmission plate 15. The offset of the transmission plate 15 synchronously moves the two transmission rods through the cooperation of the transmission rod two 17 and the transmission rod one 14. The movement of the transmission rod two 17 and the transmission rod one 14 further pushes the sliding ring one 13 and the transmission ring two 18 to slide up and down on the outer wall of the connecting column 12, thereby generating a squeezing action on the spring one 19 and the spring two 20. The squeezing makes the spring one 19 and the spring two 20 elastically deform, and stores a part of energy.

[0037] With reference to Figure 4 and Figure 5 , the transmission plate 15 is rotatably connected with the transmission rod two 17 on one side, the transmission rod two 17 is rotatably connected with the transmission ring two 18 on one side, the transmission ring two 18 slides on the outer wall of the connecting column 12, and the transmission ring two 18 is in sliding contact with the outer wall of the connecting column 12, forming a sliding fit structure. The outer wall of the connecting column 12 is provided with the spring one 19, one end of which is fixedly connected to the outer wall of the connecting column 12, and the other end is fixedly connected to the side wall of the transmission ring two 18, which provides a certain elastic constraint and adjustment for the transmission ring two 18. The outer wall of the connecting column 12 is provided with the spring two 20, which mainly provides a stable support force for the sliding ring one 13 to ensure that it does not produce excessive displacement during operation. One end of the spring two 20 is fixedly connected to the bottom of the sliding ring one 13, and the other end is fixedly connected to the outer wall of the connecting column 12.

[0038] Specifically, when the restoring force is needed, the elastic potential energy of the spring one 19 and the spring two 20 will be released to push them back to their original position, driving the sliding ring one 13 and the transmission ring two 18 to return to the initial position, thereby facilitating the operator to quickly clean the accumulated impurities in the impurity collection bucket 9. The operator only needs to pull the impurity collection bucket 9 to quickly clean the impurities and ensure that the assembly can be quickly reset and installed, thereby improving the convenience and efficiency of maintenance.

[0039] Working principle: when using the device, the operator places tea on the surface of the conveying belt 2, the conveying belt 2 slowly conveys the tea, the electrostatic adsorption roller 6 electrostatically adsorbs and removes the impurities in the tea, the removed tea will fall into the tea collecting hopper 4 under the conveying of the conveying belt 2, the electrostatic adsorption roller 6 adsorbs the impurities, and the scraper 8 can scrape the adsorbed impurities, the scraper 8 will rub on the surface of the electrostatic adsorption roller 6, and the friction force will scrape the adsorbed impurities on the surface of the electrostatic adsorption roller 6, the scraped impurities will fall into the impurity collecting hopper 9 under the further guidance of the scraper 8, and the impurities will be collected in the impurity collecting hopper 9 to prevent them from mixing into the tea, when it is necessary to clean the impurity collecting hopper 9, the operator directly pulls down the impurity collecting hopper 9, the clamping block 16 will slide in the limiting groove 11 under the action of the pulling force, the sliding of the clamping block 16 drives the transmission plate 15 to deviate, the deviation of the transmission plate 15 drives the transmission rod two 17 and the transmission rod one 14 to move synchronously, the movement of the transmission rod two 17 and the transmission rod one 14 makes the sliding ring one 13 and the transmission ring two 18 slide up and down on the outer wall of the connecting column 12, so as to extrude the spring one 19 and the spring two 20 to make them elastically deform, when the restoring force is needed, the elastic potential energy of the spring one 19 and the spring two 20 drives them to restore, so as to quickly clean the impurity collecting hopper 9 and provide convenience for the operator to maintain.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
