Description

Technical Field

[0001] The utility model relates to the technical field of white tea production impurity removal equipment, in particular to an electrostatic impurity removal equipment for characteristic white tea production. Background Art

[0002] Since there are impurities in the production and processing of tea, they need to be removed through impurity removal equipment.

[0003] Electrostatic impurity removal equipment uses friction to generate electric charges on electrostatic rollers to absorb impurities in tea leaves. Since it relies entirely on static electricity for impurity removal, it has high requirements for the environment. When the humidity is too high, the electrostatic adsorption capacity is weak, and the impurities mixed in the tea leaves cannot be completely adsorbed to the surface of the electrostatic roller, resulting in a decrease in the impurity removal effect, which is not conducive to the company's production and processing.

[0004] For example, a tea processing impurity removal device disclosed in Chinese patent CN220590351U is used to continuously transport tea leaves to be removed through a tea conveyor belt on a frame. The electrostatic rotating roller rubs against the friction cotton layer during rotation to generate static electricity. When tea leaves pass under the electrostatic rotating roller, impurities in the tea leaves are adsorbed to the surface of the electrostatic roller under the action of electrostatic adsorption to achieve impurity removal. When the ambient humidity is high, it will affect the electrostatic impurity removal effect. At this time, hot air is transported into the hot air pipe to heat the friction cotton layer with hot air, so that the electrostatic rotating roller and the friction cotton layer are kept dry, thereby ensuring the electrostatic adsorption capacity. The hot air drying method is safer and more reliable than using heating pipes, heating wires, etc., and can also avoid affecting the quality of tea leaves. It can ensure that the surface of the electrostatic rotating roller and the hot air pipe is dry, avoid excessive humidity causing a decrease in electrostatic adsorption capacity, and affect the impurity removal effect, which is conducive to improving the quality of tea leaves.

[0005] However, in the prior art, after the tea leaves are cleaned, impurities are easily accumulated inside the collection box when they are collected using the collection guide groove and the collection groove. In addition, when the impurities in the tea leaves are simply electrostatically adsorbed by the electrostatic roller, the impurities stacked at the bottom of the tea leaves cannot be well adsorbed and collected.

[0006] For this reason, we urgently need to provide an electrostatic impurity removal equipment for the production of special white tea. Utility Model Content

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] An electrostatic impurity removal device for producing special white tea comprises a conveyor belt 1, a discharging structure is installed at the right end of the conveyor belt 1, an adsorption structure is installed on the top of the conveyor belt 1, and a collecting structure is installed on the back and left end of the conveyor belt 1.

[0030] The collection structure includes a dust collection unit and a filtering and collecting unit. The dust collection unit includes a collecting box 305. An air pump 309 is installed in the middle of the left side of the collecting box 305. A dust collection pipe 304 is connected to the middle of the right side of the collecting box 305 near the top. The end of the dust collection pipe 304 away from the collecting box 305 is connected to the collecting tube 303. The top of the collecting tube 303 is connected to a connecting tube 302. The end of the connecting tube 302 away from the collecting tube 303 is connected to the collecting box 301. The filtering unit includes a limiting plate 306. The outer surface of the limiting plate 306 is connected to a filtering plate 307. A collecting drawer 308 is arranged on the right side of the filtering plate 307.

[0031] The limiting plate 306 is fixedly installed at the left end inside the collecting box 305, the outer surface of the filter plate 307 is sealed and slidably connected to the inner wall of a rectangular through hole opened in the middle of the top surface of the collecting box 305 near the left end, the outer surface of the collecting drawer 308 is sealed and slidably connected to the inner wall of a rectangular hole opened at the bottom end of the front of the collecting box 305, and the front of the collecting cylinder 303 is fixedly connected to the top of the back of the conveyor belt 1.

[0032] The adsorption structure includes an asynchronous motor 201, an electrostatic roller 204 is connected to the output end of the asynchronous motor 201, a fixing part 203 is installed on the front and back of the outer surface of the electrostatic roller 204, a linkage part 202 is connected to one end of the front of the electrostatic roller 204, and a material turning roller 205 is arranged on the right side of the electrostatic roller 204. The bottom surface of the fixing part 203 is fixedly connected to the top surface of the conveyor belt 1, the bottom surface of the asynchronous motor 201 is detachably connected to the front of the conveyor belt 1, one end of the front of the material turning roller 205 is connected to the linkage part 202, one end of the front and back of the material turning roller 205 is installed in the middle of the right side of the fixing part 203, and the outer surface of the electrostatic roller 204 is slidably connected to the right side of the collection box 301.

[0033] By setting up the collecting structure and the adsorption structure, starting the air pump 309 can pump the air inside the collecting box 305 into a negative pressure state, and using the dust suction tube 304 and the collecting tube 303 for adsorption, so that the connecting tube 302 and the collecting box 301 can be used to adsorb and collect debris to prevent the accumulation of debris. At the same time, after the debris is filtered by the filter plate 307, the debris can be collected by the collecting drawer 308 for centralized processing.
