Embodiment 1

[0015] As shown in the figure, the present invention includes an impeller chassis 1, a blade 2 is arranged on the impeller chassis 1, a cavity 3 is arranged in the center of the impeller chassis 1, 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 channel 4 through the impeller chassis air channel 6 , and the exhaust hole 5 communicates with the blade air channel 4 . Based on the previous research on the impeller of flotation machine and flotation dynamics, the impeller blade is designed as a large blade. At the same time, the impeller has air passages and side exhaust holes, which can meet the requirements of inflatable flotation machine and non-metallic ore beneficiation. Special requirements for equipment.

[0016] The working principle of the impeller is as follows: the present invention is based on the characteristics of the inflatable flotation machine and the ...

Embodiment 2

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 vent hole, 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 present invention relates to an impeller. Background technique [0002] Impellers are commonly used mechanical parts in the industry and are widely used. Different application fields have different characteristics. Among them, non-metallic mineral beneficiation and inflatable flotation machine are special, and require (1) the impeller stirring force should be moderate, so that the pulp surface should be stable. (2) The amount of pulp circulating through the impeller should be large, so that the process can be smoothly absorbed. (3) The form is reasonable, the structure is simple, and the power consumption is low. (4) It has a suitable inflation volume, the air is evenly dispersed, and the inflation volume 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 capacity, and large stirring force. In ad...
