Description

Technical Field

[0001] The utility model relates to the technical field of powder material transportation, in particular to a device for removing metal impurities from powder material pneumatic conveying. Background Art

[0002] At present, the fine-grained powders (such as cement, mineral powder, coal powder, etc.) required for construction equipment are generally pneumatically transported to storage tanks by tank trucks. When used, they are then sent to weighing tanks through conveying equipment (such as screw conveyors, feeders, etc.) and accurately weighed before use.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed "a device for removing metal impurities from pneumatically conveyed powder", and its announcement number is "CN 209423845 U". The patent mainly includes an upper joint, a filter, a lower end cover, a feed joint, a magnet seat, an industrial strong magnet, and a filter screen. The upper part of the filter is connected to the upper joint, and the lower part is equipped with a lower end cover. The middle part is provided with a magnet seat, and the magnet seat is equipped with an industrial strong magnet. The outer side of the middle part of the filter is provided with an upper powder port, and the upper powder port is connected to the feed joint, and a filter screen is provided between the two. This device is reasonably designed and simple in structure. It effectively removes metal slag in the powder, avoids the problem of metal slag blocking the conveying equipment during the powder conveying process, and eliminates the hidden danger of metal slag explosion when the powder is burned. However, when the device is used, the filter is decelerated by filtering through the filter screen, which may drive the powder to pass through the filter screen directly, and effective deceleration cannot be achieved. It may also cause the filter screen to be blocked, causing damage to the device, thereby affecting the use of the device. Utility Model Content
