A material circulation mesh belt multi-layer grading vibrating screen

Abstract

The invention relates to a device capable of achieving grading dehydration of fine materials, in particular to a novel material circulating mesh belt multi-layer vibrating grading screen. The vibrating grading screen comprises a main rack, an excitation motor, grading screen units, a chute main rack, hoppers below the screen and a driving mechanism, and the excitation motor is fixedly connected to the main rack. Each grading screen unit comprises a single-layer main framework, a driving shaft, a driven shaft and a steel mesh, wherein the single-layer main framework is fixedly connected to the main rack, the two ends of the driving shaft are each fixedly connected with a first driving chain wheel, the two ends of the driven shaft are each fixedly connected with a first driven chain wheel, and the two sides of the steel mesh are each fixedly connected with one first chain. The hoppers blow the screen are fixedly connected with the chute main rack and located under the grading screen units. Lower funnel discharge ports are formed in the bottom of the hoppers below the screen. The novel material circulating mesh belt multi-layer vibrating grading screen is simple in structure, low in fault rate, convenient to maintain, low in production cost and good in screening and dehydration effect.

Description

technical field [0001] The invention relates to a device capable of realizing classification and dehydration of fine-grained materials, in particular to a material circulation mesh belt multi-layer classification vibrating screen. Background technique [0002] At present, the dehydration of fine-grained materials has always been a key link that is difficult to solve in production enterprises. The contradiction between the moisture content of the product and the sieving particle size required by the material and the production cost is especially reflected in the dehydration and ash reduction of fine-grained materials. . [0003] In recent years, equipment for screening fine-grained materials has appeared, and the use of vibrating arc screens and laminated screens has appeared successively, especially laminated screens. Due to the high cost and price of foreign technology monopoly, and the processing capacity of a single unit is limited; domestic The same kind of equipment pr...

Problems solved by technology

[0003] In recent years, equipment for screening fine-grained materials has appeared, and the use of vibrating arc screens and laminated screens has appeared successively, especially laminated screens. Due to the high cost and price of foreign technology monopoly, and the processing capacity of a single unit is limited; domestic The same kind of equipment produced does not have good dehydration and ash reduction efficiency, and there is still a big gap with foreign technologies, and cannot meet the production indicators. The main problem of the vibrating curved screen is that the screening effect on fine-grained materials is not good. The main problem of layered sieves is that the cost is high and the processing capacity is limited. The domestic similar layered sieves have poor screening effect and cannot meet the requirements of production indicators.
