Technical Field

[0001] The utility model relates to the technical field of permanent magnetic cylinders, in particular to a permanent magnetic cylinder for removing impurities from feed. Background Art

[0002] Permanent magnetic drum is a kind of permanent magnetic iron remover, which is mainly used to remove iron impurities in dry powder materials and granular materials. Permanent magnetic drum is mainly installed in the conveying pipeline system, which can remove iron filings and larger pieces of ferromagnetic impurities from dry gravity materials or gas-driven materials. It is widely used in flour processing, mills, grain processing, material processing, kaolin or talcum powder processing and other places.

[0003] In the process of feed processing, it is necessary to use a permanent magnetic cylinder to remove impurities in the feed. During the removal process, some feed will adhere to the inner cylinder of the permanent magnetic cylinder, resulting in reduced efficiency in the removal process. After the impurities are removed, if there is still feed on the inner cylinder, it will not only affect the subsequent processing, but also cause a certain degree of waste. The feed needs to be manually removed. In view of this, we proposed a permanent magnetic cylinder for feed impurity removal. Utility Model Content

[0007] Preferably, a limiting groove is provided on the outer surface of the inner cylinder, and a connecting plate is slidably connected to the inner wall of the moving box.

[0008] Preferably, springs are fixedly connected to the upper and lower surfaces of the connecting plate, and opposite ends of the two springs are fixedly connected to the upper and lower inner walls of the moving box, respectively.

[0012] Preferably, the upper end of the anti-clogging rod extends to the interior of the feed pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When the inner cylinder of the feed impurity removal permanent magnet cylinder needs to be cleaned, the motor can be used to drive the drive disk to rotate, and the drive disk and the drive assembly can be used to drive the push rod to reciprocate up and down. The movement trajectory of the push rod is limited by the limit cylinder during movement, and after the push rod is pushed out, it contacts the upper surface of the fixed plate. Since the fixed plate itself is supported by the connecting rod and cannot move, the push rod is used to drive the inner cylinder as a whole to move up and down, and then the feed is shaken off by rapid shaking. Through the above structure, when the inner cylinder needs to be cleaned, it is only necessary to open the maintenance door or disassemble it for cleaning, so that the cleaning of the inner cylinder can be completed more conveniently and quickly, avoiding affecting the subsequent impurity removal quality.

[0015] (2) The permanent magnet cylinder for removing impurities from feed can use the connecting shaft to drive the second push rod to move up and down when the driving disk rotates, thereby driving the push rod to move. At the same time, when the feed pipe is blocked, the second motor can be used to drive the drive rod to rotate. After the drive rod rotates, the conical block is used to drive the anti-blocking rod to rotate synchronously, and the anti-blocking rod is used to scatter the feed in the feed pipe. Through the above structure, when the feed pipe is blocked, it can be more convenient to scatter it, avoiding the influence of blockage on the impurity removal efficiency, and the tapered upper surface of the conical block can also effectively reduce the probability of feed accumulation on its upper surface.
