Ultramicro black fungus powder purification system based on negative pressure

Abstract

The invention discloses an ultramicro black fungus powder purification system based on negative pressure. The system comprises a purification tank and a hollow cylinder, a feeding cavity is fixedly mounted at the top end of the purification tank; the hollow cylinder is fixedly installed at one side of the feeding cavity, a control panel is installed on the surface of the purification tank, the purification tank is fixedly installed at the top end of the support, the purification tank is trapezoidal, a magnetic sliding plate is installed on the surface of one side of the inner wall of the purification tank, and a common sliding plate is installed on the surface of the other side of the inner wall of the purification tank. According to the ultramicro black fungus powder purification system based on negative pressure, mixed powder can be preliminarily separated through the magnetic sliding plate and the common sliding plate; through an arranged coil and a solid iron core in the coil, a magnetic field can be generated when alternating current is introduced, the surface of the solid iron core has magnetism, the amount of the iron powder adsorbed on the solid iron core can be observed through the transparent hollow cylinder, and it is judged that secondary treatment does not need to be conducted on the black fungus powder.

Description

technical field [0001] The invention relates to the field of black fungus powder purification, in particular to a negative pressure-based ultrafine black fungus powder purification system. Background technique [0002] The processing device of existing black fungus powder generally comprises feeding bin, ball mill wall breaking device, iron powder removal device (because in the ball milling process, there will be iron powder mixed in the inside, blow the powder after the ball mill with blast , the black fungus powder will be blown away by the blast, and the iron powder will stick to the magnetic closed surface), the collection bin, the sub-package sealing device (sub-package and seal the collected broken-wall black fungus powder), microwave sterilization device ( Sterilization by microwave). The processing method of existing black fungus powder is: put the chopped black fungus in the feeding bin, through the ball milling process, the black fungus is broken, and the powder a...

Problems solved by technology

[0003] Under normal circumstances, the existing black fungus needs to be ground by a ball mill to grind the fungus powder during the crushing process. However, since the ball mill uses iron balls, iron powder will fall from the surface and mix into the black fungus during the grinding process. Among the powder, it will affect the purity of the black fungus powder and affect the use effect of the black fungus powder. In the prior art, the efficiency of the iron removal powder device is low. Due to the setting of the iron removal device itself, the degree of refinement is low, because During the ball milling process, there will be iron powder doped in it, and the powder after the ball milling is blown by a blast, the black fungus powder will be blown away by the blast, and the iron powder will stick to the magnetic closed surface. For this reason, we A negative pressure-based ultrafine black fungus powder purification system is proposed. Two sets of magnetic systems and one circulation system are used in conjunction with each other to improve the efficiency of iron powder removal.
