Magnetic powder screening device

Abstract

The present invention relates to the technical field of devices for magnetic particle screening, and in particular to a magnetic particle screening device. The magnetic particle screening device of the present invention can perform longitudinal adjustment of the first screen mesh and the second screen mesh, thereby improving the usability; at the same time The cover can be opened automatically, which improves work efficiency, and allows internal observation to facilitate maintenance; it includes a main body, a working chamber is provided inside the main body, and a first screen, a second screen and a magnetic selection plate are provided in the working cavity; It also includes a connecting column and a double torsion spring; an observation hole is provided on the side wall of the main body, and a transparent baffle is provided on the observation hole; a driving motor, a driving shaft and bristles are provided in the third chamber; the second chamber and the third chamber are provided with Fixed plates are provided on the inner side walls of the three chambers, and a control motor is provided on the fixed plate. The top output end of the control motor is provided with a threaded rod and a threaded pipe, and a ball bearing is provided in the placement groove.

Description

technical field [0001] The invention relates to the technical field of devices for magnetic powder screening, in particular to a magnetic powder screening device. Background technique [0002] As we all know, magnetic powder is a kind of hard magnetic single-domain particles. It is made into magnetic slurry with binders and solvents, and coated on the surface of plastic or metal substrates (supports), it can be made into magnetic tapes, magnetic disks, magnetic Cards and other magnetic recording materials, while the magnetic powder screening device is a device dedicated to screening magnetic powder, which has been widely used in related technical fields; the existing magnetic powder screening device includes a main body, and a working chamber is arranged inside the main body. The top of the main body is provided with a material inlet, the bottom is provided with a material outlet, and a cover is provided at the material inlet and the material outlet, and a first screen, a se...

[0002] As we all know, magnetic powder is a kind of hard magnetic single-domain particles. It is made into magnetic slurry with binders and solvents, and coated on the surface of plastic or metal substrates (supports), it can be made into magnetic tapes, magnetic disks, magnetic Cards and other magnetic recording materials, while the magnetic powder screening device is a device dedicated to screening magnetic powder, which has been widely used in related technical fields; the existing magnetic powder screening device includes a main body, and a working chamber is arranged inside the main body. The top of the main body is provided with a material inlet, the bottom is provided with a material outlet, and a cover is provided at the material inlet and the material outlet, and a first screen, a second screen and a magnetic The selection board divides the working chamber into the first chamber, the second chamber, the third chamber and the fourth chamber, the inlet is communicated with the first chamber, the outlet is communicated with the fourth chamber, and in There are multiple feeding ports on the magnetic separation plate, a motor is arranged on the top of the main body, a transmission shaft is provided at the output end of the motor, and three sets of stirring paddles are arranged on the transmission shaft. The first set of stirring paddles is located in the first chamber. The second set of agitating paddles is located in the second chamber, the third set of agitating paddles is located in the third chamber, and a bracket is provided under the main body; it is found in the use of this magnetic powder screening device that when it is working, especially in the third chamber Internal observation cannot be carried out during stirring and final screening, which is inconvenient for maintenance and is very troublesome; and the cover of the discharge port needs to be opened manually, which is very troublesome, wastes manpower and material resources, and reduces work efficiency; at the same time, due to the first screen and the second screen are fixed, resulting in the space of the first chamber, the second chamber and the third chamber cannot be adjusted, resulting in poor adaptability
