Embodiment 1

[0015] As shown in the figure, the present invention includes an impeller chassis 1, on which a blade 2 is arranged, the center of the impeller chassis 1 is provided with a cavity 3, and a blade air channel 4 and an exhaust hole 5 are opened on the blade 2, and the impeller The cavity 3 in the center of the chassis communicates with the blade air passage 4 through the impeller chassis air passage 6 , and the exhaust hole 5 communicates with the blade air passage 4 . Based on the research on the previous flotation machine impeller and flotation dynamics, the impeller blades are designed as large blades. At the same time, there are air passages and side exhaust holes inside the impeller to meet the requirements of inflatable flotation machines and non-metallic ore beneficiation. Equipment specific requirements.

[0016] The working principle of the impeller is: the invention is based on the characteristics of the inflatable flotation machine and non-metallic ore beneficiation. ...

Abstract

The invention discloses an inflatable impeller, which comprises an impeller chassis on which a vane is arranged, the center of the impeller chassis is provided with a cavity, the vane is provided with an air passage of the vane and a vent hole, the cavity in the center of the impeller chassis is communicated with the air passage of the vane through an air passage of the impeller chassis, and the vent hole is communicated with the air passage of the vane. The inflatable impeller has the following advantages that the impeller is designed into large vane, and the outside contour line is a curve,so as to form proper stirring strength at lower rotating speed, stabilize ore slurry level, and improve sorting index of nonmetallic ore. The lateral surface of the impeller is provided with the venthole, and air is thrown away by the rotating impeller from the vent hole on the lateral surface, so the inflatable impeller has the advantages of even air dispersion, fine and even bubbles, good foaming performance, good flotation effect, and the like. The impeller integrates stirring and inflating into a whole, and has a simple structure and low energy consumption.

Description

technical field [0001] The invention relates to an impeller. Background technique [0002] The impeller is a commonly used mechanical component in industry and is widely used. Different application fields have different characteristics. Among them, the beneficiation of non-metallic minerals and the inflatable flotation machine are special, requiring (1) the stirring force of the impeller should be moderate, so that the pulp surface should be stable. (2) The amount of pulp circulation through the impeller should be large, so that the process can be smoothly sucked. (3) The form is reasonable, the structure is simple, and the power consumption is low. (4) It has a suitable amount of air, the air is evenly dispersed, and the amount of air can be adjusted arbitrarily. At present, domestic flotation machines, such as JJF type, XJZ type, SF type, BF type, etc., have the common characteristics of their impellers: self-suction, large suction volume, and large stirring force. In ...
