Embodiment Construction
[0024] The micron-level energy-saving double-impeller superfine classifier provided by the present invention greatly improves the classification accuracy through structural improvement, and can be widely used in the deep processing of minerals, the superfine requirements of new materials, and the superfine classification of food and pharmaceutical industries and chemical raw materials. Deep Processing. The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 As shown, the micron-scale energy-saving double-impeller superfine classifier provided by the present invention includes a lower chamber, a middle chamber 20 and an upper chamber 30 that are sequentially combined from bottom to top. The direction of the arrow is the movement direction of the material with the airflow.
[0026] The lower cavity is composed of a feed pipe 10 and a slag discharge pipe 40. The feed pipe 10 is use...

The invention discloses a micron-grade energy-saving type double-impeller superfine classifier. The micron-grade energy-saving type double-impeller superfine classifier comprises a lower cavity, a middle cavity and an upper cavity. A material distribution cone is arranged in the middle cavity. Apassage which allows materials to continue rising is formed between the outer sidewall of the material distribution cone and the middle cavity. Two grading devices and corresponding air sealing devices are arranged on the two side faces of the upper cavity respectively. Each grading device comprises a support, a grading impeller and a variable frequency motor for driving the grading impeller to rotate at a high speed. Each air sealing device comprises air pipes, a plurality of mounting bases and a sealing base, wherein the mounting bases are evenly fixed to the outer side face of the corresponding support in the circumferential direction of the air pipes, the sealing base is fixed to the inner side face of the corresponding support, and the two ends of each air pipe are connected with the corresponding mounting base and the sealing base respectively. Through the structural improvement, grading accuracy is greatly improved, and the micron-grade energy-saving type double-impeller superfine classifier can be widely applied to deep processing of minerals, superfine processing of new materials, and superfine deep processing of raw materials in food industry, medical industry, chemical industry and the like.
Description
technical field [0001] The invention relates to a classifier, in particular to a micron-level energy-saving double impeller superfine classifier. Background technique [0002] Airflow classifiers are widely used in chemical industry, minerals (especially suitable for the classification of non-mineral products such as calcium carbonate, kaolin, quartz, talc, mica), metallurgy, abrasives, ceramics, refractory materials, medicine, pesticides, food, health care products, new materials, etc. industry. [0003] Under the suction of the induced draft fan unit, the material enters the inner cavity from the feed inlet at the lower end of the air classifier, and moves to the classification area at high speed with the updraft. Under the strong centrifugal force generated by the high-speed rotating sorting device, the material The coarse and fine materials are separated, and the fine particles that meet the particle size requirements enter the discharge chamber through the gap between ...
