A two-stage powder selection mechanism for cement production

Abstract

The invention discloses a two-stage powder selection mechanism for cement production, comprising an outer cylinder, the inner cylinder of the outer cylinder is provided with a first cavity and a second cavity, and the first cavity and the second cavity are Separated by a partition, the interior of the partition is provided with a round hole. The present invention can drive the inner cylinder to rotate through the provided motor; the rotation of the inner cylinder can make the first rotating shaft and the fan blades rotate; The motor can realize the whole process of sorting the cement powder without adding any other electrical equipment, which not only reduces the use of equipment, saves resources, reduces the cost, but also reduces the energy consumption of the equipment accordingly. It will not cause the powder to fly everywhere, reduce the dust content in the air environment inside and around the factory as much as possible, protect the environment, and respond to the national energy conservation and environmental protection policy.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a two-stage powder selection mechanism for cement production. Background technique [0002] There are three main types of existing powder separators: centrifugal powder separator, cyclone powder separator and three-separation powder separator. Centrifugal powder separator is an internal circulation air powder separator. There are obvious defects in the principle of classification, so that the powder selection efficiency of the powder separator is low, and the fineness adjustment is difficult; the cyclone powder separator separates the two processes of separation and fine powder collection on the basis of the centrifugal powder separator, which improves the efficiency of fine powder collection. The ability to collect fine powder, but still retains the characteristics of the centrifugal powder separator in the classification principle; that is, the use of gravity classifi...

[0002] There are three main types of existing powder separators: centrifugal powder separator, cyclone powder separator and three-separation powder separator. Centrifugal powder separator is an internal circulation air powder separator. There are obvious defects in the principle of classification, so that the powder selection efficiency of the powder separator is low, and the fineness adjustment is difficult; the cyclone powder separator separates the two processes of separation and fine powder collection on the basis of the centrifugal powder separator, which improves the efficiency of fine powder collection. Fine powder collection ability, but still retains the characteristics of centrifugal powder separator in the classification principle; that is, the use of gravity classification; the third generation of high-efficiency powder separator has a new breakthrough in the classification principle: use centrifugal force field for classification

[0003] Existing cement and other production enterprises need to use the volute of the powder separator, which has an independent air supply mechanism inside, but the air supply volume, air supply pressure and air supply speed of the existing air supply mechanism are generally Fixed and non-adjustable, resulting in incomplete separation of coarse powder and fine powder in the cement production process, resulting in poor powder selection effect and low efficiency of the powder separator, which affects the production quality of cement. A large amount of electric equipment is used for auxiliary powder selection, which not only has high production costs, but also wastes power resources and increases the economic burden of the factory
