Embodiment 1

[0050] Such as figure 1 As shown, an industrial silo with a diameter of 3m, a height of the straight section of 8m, a full cone angle of 60°, and a silo outlet of 200mm is equipped with a new type of feed distributor, baffle and auxiliary fluid.

[0051] The feed distributor is connected to the end of the conveying pipeline through a flange. The height of the feed distributor from the top of the silo is 400mm, and the diameter of the feed pipe is 150mm. After circular processing, it is connected with the distribution pipe by welding. Each sector corresponds to a distribution pipe. The diameter of the distribution pipe is 60mm. Based on the good fluidity of the powder, the axial angle between the distribution pipe and the feed pipe is 50°. The outlet of the feed distributor is a vertical pipe with a diameter of 60mm and a length of 300mm.

[0052] The 6 baffles divide the straight section of the silo equally into 6 areas, that is, 6 small silos. The 6 baffles are welded tog...

Abstract

The invention discloses a powder stock bin. The stock bin comprises a straight barrel section and a conical section. The stock bin comprises a feed distributor (1), a baffle (5) and auxiliary fluid (7). The feed distributor is mounted on a stock bin inlet and provided with multiple distribution pipes, and it is guaranteed that powder perpendicularly flows into the stock bin in multiple passageways. The baffle is arranged in the region of the straight barrel section of the stock bin, each distribution pipe corresponds to one distribution region, and outlets of the distribution pipes and the centers of the regions are located on the same vertical line. The auxiliary fluid is arranged in the conical section of the stock bin, and the flow form of the powder is improved. Separation of particlesof the powder in the radial direction and the axial direction can be reduced, it is guaranteed that in the feeding and discharging processes, the powder in all the regions flows smoothly, and particle size distribution is uniform, the particle size stability of the powder is improved, and the product quality is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of powder engineering, in particular to a powder silo. Background technique [0002] Particle fluidity is an important factor affecting particle handling and processing, and particle size directly determines its fluidity. As a buffer and storage silo, it is necessary to regulate the particle size of the powder, so as to avoid the large difference in the particle size of different batches of products, which will affect the product quality. [0003] In order to solve the problem of powder material homogenization and poor fluidity, mixing technology is widely used in the field of material homogenization, but with the improvement of scale and intelligence in the chemical industry, the high energy consumption, low production capacity and failure rate of ordinary mixing technology High disadvantages seriously restrict the expansion of product scale. With the development of science and technology, some emerging technologie...
