Method for removing impurity in the process of air delivery of powdered materials

Abstract

The invention relates to a method that removing foreign matters in the powder air feeding process, which adds a foreign matter removing device on the pipe that from the middle storage pot to the final storage post. Wherein, the foreign matters removing device comprises a case and a screen plate, while the left of case has a inlet, the right of case has a outlet, and the upper and lower parts of case have hand holes; the screen plate is arranged between the upper and lower cases, while it has screen holes with 30-45% hole percentage.

Description

Technical field [0001] The present invention belongs to the technical field of solid material transportation, and relates to a method for removing foreign matter during powder transportation. Background technique [0002] Industrialized production and the final product appearance of the powdery production process generally includes the following steps: oxidation or reduction reaction, product crystallization, product separation, product drying, product storage and packaging and other processes to meet the requirements A product that the customer must request. [0003] In this production process, foreign matter (such as bolts, nuts, brackets, etc.) sometimes enters the product crystallization and product separation process; while the drying process of the product inevitably produces lumps and foreign matter; product storage and Packaging and other processes are easily mixed with foreign matter, which will have a certain impact on downstream production equipment or customers’ produ...

AI Technical Summary

Problems solved by technology

[0003] During this production process, foreign matter (such as bolts, nuts, brackets, etc.) sometimes enters the product crystallization and product separation processes; while the product drying process inevitably produces lumps and foreign matter; product storage and Packaging and other processes are easy to mix foreign matter, which will have a certain impact on the downstream production equipment or the customer's production and operation equipment. However, the use of vibrating screen separation and removal equipment, due to the inconvenience of operation and maintenance, the actual use effect is not good, and it cannot be widely used. to promote and utilize

[0004] At the same time, most production processes generally do not process lumps or foreign matter in products, and very few production processes use vibrating screen separation and removal equipment
