Description

Technical Field

[0001] The invention relates to the technical field of roller electrostatic machines, in particular to a roller electrostatic machine for removing impurities from tea leaves and a use method thereof. Background Art

[0002] Electrostatic adsorption is a process in the tea refining process to remove light and soft impurities in the tea leaves, such as weeds, woven bag silk, and hair. After adsorption and cleaning, more impurities will accumulate on the electrostatic roller of the roller electrostatic machine, which will reduce the impurity removal effect.

[0003] In this regard, in the prior art, there is also a technology of scraping away impurities by setting a scraper on the side of the electrostatic roller. For example, in the prior art, the patent with the announcement number CN221183200U discloses an electrostatic impurity removal device for tea production; a scraper and a drainage trough are set on one side of the electrostatic roller, and the scraper is used to scrape off impurities on the outside of the electrostatic roller. However, this simple method of laminating the residue still has the following shortcomings when used:

[0004] 1. It is difficult to ensure that the scraper and the electrostatic roller are always in stable contact. The scraper is easily separated from the electrostatic roller due to factors such as relative friction, and the long-term contact and scraping stability is not ideal; 2. The impurities are discharged outward along the scraper. Since the impurities adsorbed by static electricity are light and relatively soft, they are easily caused by vibration, gas circulation and other factors to float up again and fall into the tea leaves. It is difficult to stably clean the impurities and collect them separately, and the cleaning stability is poor. In view of this, the present application proposes a roller electrostatic machine for removing impurities from tea leaves and a method of using the same to solve the above-mentioned problems.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The tea leaves can be transported by cooperating with the U-shaped bracket and the tea leaves conveying assembly;

[0027] 2. The inverted U-shaped plate, rotating shaft, electrostatic roller, tea-moving assembly and linked rotary drive assembly cooperate to move and scatter the tea leaves during transportation, so as to disperse the light and soft impurities remaining inside the tea leaves, and the light and soft impurities can be cleaned by electrostatic adsorption after being scattered;

[0028] 3. The scraper, the circular seat and the elastic support assembly can be used to scrape and concentrate the impurities adsorbed on the outside of the electrostatic roller, and the elastic tension can be used to ensure that the scraper and the electrostatic roller are always in a long-term and stable fit to prevent separation, thereby preventing the phenomenon of separation due to wear and tear that reduces the scraping effect, and improving the long-term and stable scraping effect;

[0029] 4. Through the cooperation of the set slag box, exhaust fan, filter net and L-shaped suction pipe, the scraped and concentrated impurities can be directly sucked and filtered and collected into the slag box automatically, preventing the impurities from being scattered and mixed into the tea leaves again due to external vibration, gas circulation and other factors, thereby improving the stability of impurity cleaning and collection, thereby improving the impurity removal effect on tea leaves;

[0030] 5. Through the cooperation of the set slag collecting box, exhaust fan, filter, self-unsealing backblowing cleaning and dredging component and slag discharge component, the filter can be backblown, cleaned and dredged after use, and the impurities can be automatically discharged and collected into the external breathable dust collecting bag. There is no need for personnel to remove the filter for cleaning later, which is convenient for disassembly and assembly-free cleaning and dredging work. Because the impurities are lighter, softer and smaller in size, the breathable dust collecting bag can be used to collect them many times and then remove and pour out the impurities, reducing the cleaning frequency. The breathable dust collecting bag is located on the outside to facilitate the subsequent removal and cleaning work, thereby improving the convenience of subsequent use.

[0031] The present invention is provided with a series of structures, which is convenient for shaking the scattered and electrostatically adsorbed light and soft impurities of the tea leaves when they are transported, and is convenient for ensuring that the scraper always stably scrapes and concentrates the impurities adsorbed on the outer side of the electrostatic roller by means of elastic tension, thereby improving the long-term stable scraping effect, facilitating the direct suction, filtration and collection of the scraped and concentrated impurities, preventing the impurities from being scattered and mixed into the tea leaves again due to external vibrations, gas circulation and the like, thereby improving the stability of impurity cleaning and collection, and facilitating the backblowing, cleaning and dredging of the filter net after use, and automatically discharging and collecting the impurities into an external breathable dust collecting bag, thereby facilitating the internal cleaning and dredging work without disassembly and assembly, thereby improving the convenience of use.

When the slider 14 moves to the right, the scraper 12 is squeezed and driven by the connecting rod 16 to automatically rotate downward and fit with the electrostatic roller 4 again, so as to achieve the effect of adaptively pushing the scraper 12 to fit with the electrostatic roller 4 when the scraper 12 is worn, and prevent the phenomenon that the scraping effect is reduced due to separation caused by wear, thereby improving the long-term stable scraping effect;

[0056] S5: The exhaust fan 20 is used to suck the inside of the slag collecting box 17, and the filter screen 18 is used to filter and block. The slag collecting box 17 directly sucks and collects the scraped and concentrated impurities into the inside through a plurality of L-shaped suction pipes 19, so as to prevent the impurities from being scattered and mixed into the tea leaves again due to external vibration, gas circulation and other factors, thereby improving the stability of impurity cleaning and collection;

[0057] S6: After use, the electric telescopic rod 25 is used to drive the U-shaped baffle 23 to move upward, the U-shaped baffle 23 is unblocked to the right side of the hair dryer 21, and the transverse baffle 24 is driven upward to block the bottom of the exhaust fan 20, the hair dryer 21 is turned on to blow air to the right, and the filter 18 is automatically back-blown to the right to clean and dredge the slag. When the U-shaped baffle 23 moves upward, the blockage of the left end of the L-shaped slag discharge pipe 26 is released upward, and the impurities blown to the right are discharged through the L-shaped slag discharge pipe 26 and collected in the breathable dust collecting bag 28, so that the use is realized. The effect of automatically discharging and centrally collecting impurities during the back-blowing cleaning and dredging is achieved. The filter 18 is automatically back-blown for cleaning and dredging, and there is no need for personnel to subsequently remove the filter 18 for cleaning, which is convenient for cleaning and dredging without disassembly. Moreover, since the impurities are light and soft, and have a small size, the breathable dust collecting bag 28 can be used to collect them for many times and then remove and pour out the impurities, thereby reducing the cleaning frequency. The breathable dust collecting bag 28 is located on the outside to facilitate the subsequent removal and cleaning work, thereby improving the convenience of subsequent use.

[0058] In addition, after the slag is cleared, the electric telescopic rod 25 is started forward to drive the U-shaped baffle 23 to move back downward and reset, and the right side of the hair dryer 21 and the left end of the L-shaped slag discharge pipe 26 are blocked again. The U-shaped baffle 23 drives the cross baffle 24 downward to release the blockage of the exhaust fan 20, so that the suction and collection work during scraping can be carried out again.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
