Description

Technical Field

[0001] The utility model belongs to the technical field of grain iron removers, in particular to a foreign matter blocking device for grain iron removers. Background Art

[0002] Permanent magnetic iron remover is a device that uses the property of magnets to absorb iron products to achieve iron removal within an effective range. Due to its wide adaptability, it is widely used in feed, chemical, pharmaceutical and other industries. For the grain field, common iron removers include wheat permanent magnetic drum iron remover, powder permanent magnetic drum iron remover, etc.

[0003] In the grain industry, iron removers are generally used to remove iron magnetic impurities in grain during grain transportation. However, since the material passes through the annular channel between the inner and outer cylinders at a too fast speed, the ferromagnetic foreign matter in the material may pass through the annular channel without being adsorbed, resulting in reduced magnetic separation efficiency.

[0004] The utility model patent with application number CN200820179237.0 discloses a permanent magnetic cylinder, which reduces the material descent speed and changes the descent route by setting a baffle plate on the inner wall of the outer cylinder of the permanent magnetic cylinder, thereby improving the magnetic separation efficiency. However, for grain raw materials, some other non-magnetic foreign matter left over from the previous production process, such as wire ropes, plastic ropes, etc., will still be entrained when entering the warehouse, and the iron remover of the patent cannot block these foreign matter. These foreign matter will enter the mill after the grain raw material is discharged, and will be entangled on the feeding roller inside the mill, resulting in uneven discharge of the equipment; and as the mill continues to work, the temperature inside the machine will continue to rise, and the excessively high temperature will cause some foreign matter such as plastic ropes to melt and decompose, thereby releasing harmful substances, which will not only pollute the grain, but also cause safety hazards when the equipment is running. Therefore, it is urgent to provide a device that can solve the above problems. Utility Model Content

The shapes of the first blocking portion and the second blocking portion are both unclosed rings, and the second blocking portion surrounds the first blocking portion. The first blocking portion is provided with a plurality of first baffles 4 evenly arranged along the circumferential direction. By setting a plurality of first partitions 4, the first blocking part can be divided into a plurality of annular sector-shaped first blocking gaps 41, and the gap size of the first blocking gap 41 is adaptively adjusted according to the type of grain and its volume, so that while ensuring that the grain raw materials can pass smoothly, large foreign objects such as ropes and plastic ropes can be blocked on the first blocking part. Similarly, the second partition 5 can divide the second blocking part into a plurality of annular sector-shaped second blocking gaps 51. Since the second blocking part surrounds the first blocking part, the area of ​​the second blocking part is naturally larger than the first blocking part.

The first baffle 32, the second baffle 33 and any two adjacent second partitions 5 form a fan-shaped second blocking gap 51. Since the first blocking part is closer to the permanent magnet 2 than the second blocking part, the area of ​​the second blocking part is larger. The gap size and number of the second blocking gap 51 can be adaptively adjusted according to the area of ​​the second blocking part to ensure that the grain raw materials passing through the second blocking part can pass smoothly, but can stop large non-magnetic foreign objects such as wire ropes and plastic ropes, so that the foreign objects do not leave the iron remover with the grain raw materials.

The locking platform 61 is arranged on the first connecting member 34, and the matching platform 62 is arranged on the second connecting member 35. A gap is left between the locking platform 61 and the matching platform 62. The locking member 63 is used to fix the position of the locking platform 61 and the matching platform 62 or release the position fixation of the locking platform 61 and the matching platform 62.

[0033] The number of the locking components is two. As can be seen from the above structure, the provision of two locking components can further ensure the fixing effect of the blocking unit 3 on the permanent magnet 2. The specific sizes of the two locking components can be adaptively adjusted according to the location of the settings.
