Description

Technical Field

[0001] The utility model relates to the technical field related to powder conveying devices, and in particular to a conveying and filtering structure and system for powders. Background Art

[0002] Powder refers to the form of a collection of solid particles in a discrete state. However, powder also has the properties of fluids: it has no specific shape and can flow and fly. It is the powder that exhibits unique properties and incredible phenomena in processing, handling, and use. Although there is no clear definition in physics, "powder" is considered to be the fourth form of the state of matter, that is, the transitional state between fluid and solid. Powder is an aggregate composed of a large number of particles and the gaps between particles. The composition of powder should meet the following three conditions: the basic unit at the microscopic level is a small solid particle; at the macroscopic level, it is an aggregate of a large number of particles; and there is interaction between particles.

[0003] In powder production, grinding machines are usually used to grind mineral raw materials into powder products. Currently, the commonly used grinding machines include ball mills and Raymond mills. When the powder is transported to the grinding machine, the powder in the feed bin is generally directly sucked into the material receiving bin through a vacuum pump. In this process, powders of uneven sizes are easily caused to enter the material receiving bin, thus affecting the subsequent grinding process.

[0004] At present, no effective solution has been proposed for the problem in the related technology that powders enter the material receiving bin in different sizes, which affects the subsequent grinding process. Utility Model Content

[0214] After the vacuum treatment, the vacuum device is turned off and the third inlet and outlet element 123 is closed;

[0215] Open the first inlet and outlet element 112. Since the storage element 111 is in a negative pressure state, the powder in the feeding device is sucked into the storage element 111.

[0216] Open the discharge element 113 to discharge the sucked powder into the material receiving device through the filter element 141;
