A continuous Chinese medicine powder impurity removal device

Abstract

The invention discloses a continuous Chinese medicine powder impurity removal device, which belongs to the field of traditional Chinese medicine production equipment, and comprises a mixed adsorption tank, a medicine powder separation tube, a demagnetization drying box and a magnetic ball lifting mechanism connected in sequence. The upper end of the magnetic ball lifting mechanism is equipped with a The magnetic ball return pipe connected to the mixed adsorption tank; the inner surface of the mixed adsorption tank is provided with a spiral feeding track, the mixed adsorption tank can be driven by a motor to rotate, and there are several magnetic balls built in the mixed adsorption tank; the lower end of the powder separation tube is connected to the demagnetization Drying oven, demagnetization drying oven is equipped with electric heating elements, demagnetization drying oven is equipped with demagnetization filter plate, one side of demagnetization drying oven is equipped with a magnetic ball return port connected to the lower end of the demagnetization filter plate, and the magnetic ball is lifted The lower part of the mechanism is provided with a port communicating with the return port of the magnetic ball, and a strong magnetic field generator is provided in the mixing adsorption tank; filter holes are arranged at the bottom of the medicine powder separation tube, and a drying chamber is provided in the demagnetization drying box. The invention can improve the impurity removal effect of the medicinal powder, avoid the waste of the medicinal powder, and realize relatively stable continuous production.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine production equipment, in particular to a continuous Chinese medicine powder impurity removal device. Background technique [0002] Traditional Chinese medicine originated in China. Under the guidance of Chinese medicine theory, it is used to prevent, diagnose, treat diseases or regulate human body functions. There are also animal medicines, mineral medicines and some chemical and biological products. Traditional Chinese medicine has been developed and used in my country for thousands of years. history. However, during the use of traditional Chinese medicine, it is often necessary to crush and grind Chinese medicinal materials before they can be used as medicine. During the excavation and transportation of traditional Chinese medicine, impurities such as magnetic impurities and sediment are often mixed, which affects the quality of Chinese medicine. Therefore, it is necessary to remove i...

Problems solved by technology

It has the following disadvantages: when there are many impurities adsorbed on the electromagnetic roller, it will obviously affect the adsorption capacity of the electromagnetic roller, and then affect the removal effect of impurities in the powder; and it needs to be shut down to clean up the impurities on the electromagnetic roller, resulting in non-continuous Production

But it has the following disadvantages: the air around it rotates during the rotation of the magnetic impurity removal roller, and there is also a suction device to suck wind on one side, so that part of the Chinese medicine powder may be collected together with the impurities, even just with the magnetic The Chinese medicine powder separated from impurities is collected together with the magnetic impurities, resulting in secondary mixing, resulting in waste of Chinese medicine powder; the magnetic impurity removal roller includes multiple impurity removal magnet plates (using the principle of electromagnets), and each impurity removal magnet plate A proximity switch is attached. When the proximity switch reaches the first sensing unit, it controls the power-off of the corresponding impurity removal magnet plate, and at the same time turns on the air suction device to collect impurities. When the proximity switch reaches the second sensing unit, it controls the corresponding impurity removal magnet plate to be energized. , to participate in the work of adsorbing impurities, the control is more cumbersome, and the proximity switch and sensing unit are frequently operated, and the service life is short, which is not conducive to the continuous operation of the device
