Problems solved by technology

[0003]In the prior art, when the magnetic powder is dried, the magnetic powder is often in a piled state, resulting in uneven heating, and cannot fully contact with the hot air used for drying. It leads to low drying efficiency and uneven drying, and it is easy to affect the quality of the dried magnetic powder

Embodiment 1

[0045] see figure 1 , a self-changing path magnetic powder circulation drying furnace, including a furnace body 1, two mutually symmetrical air holes 2 are installed on the upper end, and the two air holes 2 are respectively used for introducing hot air flow and exhaust gas, and the upper end of the furnace body 1 is fixedly connected There is a feed port 3, and a pipe 4 is connected between the outer end of the lower part of the furnace body 1 and the feed port 3, and a powder delivery pump is installed on the pipe 4, and two mutually symmetrical deflection magnetic plates are fixedly connected inside the furnace body 1. There are multiple groups of evenly distributed dispersing swing plates 6 fixedly connected between the two deflection magnetic plates.

[0046] see figure 2 The deflection magnetic plate includes an electromagnetic plate 51 electrically connected to the inner wall of the furnace body 1, an outer bulge plate 53 outside the electromagnetic plate 51, and an o...

Abstract

The invention discloses a path self-changing type magnetic powder circulation drying oven, and belongs to the field of drying ovens.The path self-changing type magnetic powder circulation drying oven is characterized in that deviation magnetic plates and dispersion shaking plates are arranged, the deviation magnetic plates are powered on in a staggered mode in the drying process, on one hand, deviation attraction force is generated on falling magnetic powder, and on the other hand, the deviation magnetic plates are powered on; on the other hand, part of falling magnetic powder falls onto the dispersion swaying plate, the magnetic powder and the dispersion swaying plate collide due to acceleration, part of the magnetic powder is dispersed, and in addition, under the power-on effect, the dispersion swaying plate inclines, so that the magnetic powder is dispersed in the dispersion swaying plate, and the magnetic powder is dispersed in the dispersion swaying plate. Part of non-scattered magnetic powder located in the scattering shaking plate slides down along the scattering shaking plate, so that the powder scattering effect is achieved, the dispersity is further improved, and compared with the prior art, the drying uniformity and efficiency are remarkably improved, and the quality of the dried magnetic powder is improved by enabling the magnetic powder to continuously and circularly fall and be scattered through the powder conveying pump.

Description

technical field [0001] The invention relates to the field of drying furnaces, more specifically, to a path self-changing magnetic powder circulation drying furnace. Background technique [0002] Magnetic powder, a hard magnetic single domain particle. It is made into a magnetic slurry with adhesives, solvents, etc., and coated on the surface of a plastic or metal substrate (support), it can be made into magnetic recording materials such as magnetic tapes, magnetic disks, and magnetic cards. Magnetic powder is the core component of magnetic coatings and the main factor determining the magnetic properties of magnetic recording media. [0003] In the prior art, when the magnetic powder is dried, the magnetic powder is often in a piled state, resulting in uneven heating, and cannot fully contact with the hot air used for drying, resulting in low drying efficiency, uneven drying, and easy to affect the drying efficiency. The quality of magnetic powder after drying. Contents o...
