Filtering wind wheel of powder concentrator

Abstract

The invention discloses a filtering wind wheel of a powder concentrator. The filtering wind wheel comprises a wheel body and a shaft sleeve which is arranged in the center of the wheel body. Spokes are connected between the wheel body and the shaft sleeve. A plurality of blades which are parallel to the wheel body in the axial direction are evenly installed on the periphery of the wheel body. Filter gaps are formed between the multiple blades, and included angles are formed between the multiple blades. According to the filtering wind wheel, the multiple blades parallel to the wheel body in the axial direction are evenly installed on the periphery of the wheel body, the filter gaps are formed between the multiple blades, the included angles are formed between the multiple blades, the wind wheel rotates at a high speed, thus, air convection from outside to inside is formed on the side face of the wind wheel through air, powder can enter the wheel body under the action of air flow, the powder which is large in size cannot enter the wheel body under the filtering action of the filter gaps and adheres to the outer wall of the wheel body, the powder which is large in size can fall easily after accumulation, a certain filtering function is achieved, the mode that in the traditional technique, a filter screen is used for filtering is replaced, the filtering wind wheel is simple in structure and has dual functions of air sucking and filtering, and the powder selecting efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of concrete manufacturing equipment, in particular to a filter wind wheel of a powder classifier. Background technique [0002] In the cement processing and manufacturing process, the semi-finished product after roller milling is usually a mixture of coarse and fine, which needs to be selected before it can be packaged and sold as a finished product. In this process, a powder separator is needed. The wind wheel on the traditional powder separator is generally only The ventilation makes the inside of the machine form air convection, and the filter screen is needed to filter the powder with unqualified shape and size. The filter screen is easy to be blocked during use, which affects the efficiency and quality of powder selection. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the pre...

[0002] In the cement processing and manufacturing process, the semi-finished product after roller milling is usually a mixture of coarse and fine, which needs to be selected before it can be packaged and sold as a finished product. In this process, a powder separator is needed. The wind wheel on the traditional powder separator is generally only The ventilation makes the inside of the machine form air convection. Filtering powder with unqualified shape and size also requires a filter screen. The filter screen is easy to be blocked during use, which affects the efficiency and quality of powder selection.
