Hermetic powder concentrator capable of adjusting fineness of materials

Abstract

The invention discloses a hermetic powder concentrator capable of adjusting fineness of materials and relates to the technical field of powder concentrators. The hermetic powder concentrator capable of adjusting fineness of materials comprises a body and a multi-stage separation grain size adjusting system, wherein an air outlet box is mounted at the top end of the body, a base is fixed to the bottom end of the body, and a fine powder discharge pipe is connected to one side of the top end of the air outlet box; and the multi-stage separation grain size adjusting system is mounted in the body and a coarse powder discharge pipe extending out of the body is connected in the multi-stage separation grain size adjusting system. By arranging a filter device, air can be filtered through a mountingframe and a filter screen in the mounting frame, so that dust in air is removed, dust is prevented from overflowing into the body, and dust is prevented from being doped in cement powder, and therefore, use of the cement powder is facilitated, the practicality of the powder concentrator is improved effectively, and use of the powder concentrator is facilitated.

Description

technical field [0001] The invention belongs to the technical field of powder separators, and in particular relates to a sealed powder separator capable of adjusting the fineness of materials. Background technique [0002] In the process of cement production, it is generally necessary to use equipment to process cement such as coal mill, raw material unloading dry mill or cement mill. In coal mills, raw meal drying mills and cement mill systems, classifiers are gradually being widely used to facilitate the sorting after cement grinding and realize the use of cement. Powder separators can be divided into three categories: three-separation separators, centrifugal separators, and cyclone separators. [0003] However, there are certain defects in the use of sealed powder separators that can adjust the fineness of materials on the market. For example, there is no filter device, and the air cannot be filtered, which will easily cause dust to overflow into the interior of the mach...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sealed powder classifier that can adjust the fineness of materials, so as to solve the problem that the air cannot be filtered in the above-mentioned background technology, and it is easy to cause dust to overflow into the interior of the machine body with the air, resulting in the mixing of cement powder At the same time, the cement powder is easy to agglomerate, resulting in the formation of large particles of cement powder, which is not convenient for the selection of cement powder. In addition, the cushioning of the powder selection machine cannot be realized, which will easily lead to poor stability of the powder selection machine and is not convenient for selection. The problem of the stable operation of the powder machine
