Problems solved by technology

These traditional vibration methods have a good screening effect for materials with large particle sizes, but the screening efficiency is low for fine-grained powder materials with small particle sizes.
Due to the small monomer weight of the material to be screened, compared with its own gravity, the friction force exerted by the surrounding materials and the screen is significantly increased by the material particles, and the material to be screened can pass through the sieve hole only by its own gravity and screened less efficient

Abstract

The invention provides a screening machine, and relates to the technical field of material screening machines. The screening machine comprises a supporting body and a screening tool fixedly arranged on the supporting body; the screening tool is connected with a first drive device used for driving the screening tool to vibrate, an elastic bag type assembly is arranged on the outer side of the screening tool, and comprises a first hollow bag body and a second hollow bag body, the first bag body is detachably and fixedly connected to the lower end of the screening tool, the second bag body is detachably and fixedly connected to the upper end of the screening tool, and a sealed containing space is formed among the first bag body, the second bag body and the screening tool; the elastic bag type assembly is externally connected with a second driving device used for driving the assembly to generate vertical reciprocating deformation, the technical problem that in the prior art, a screening machine is low in microgranular powder screening efficiency and generates raised dust is solved, and the technical effect of improving the screening efficiency of the microgranular powder material is achieved.

Description

technical field [0001] The invention relates to the technical field of material screening machinery, in particular to a screening machine. Background technique [0002] The sieving machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the sieve holes and sieve the material. It is widely used in metallurgy, building materials, chemical industry, food, mining and other industries. [0003] The vibration source of the existing sieving machine is a vibration exciter, and the sieve tool produces circular, elliptical or straight-line vibrations under the action of the vibration exciter. Due to the vibration of the screen surface, the material layer on the screen surface is loosened and thrown away from the screen surface, so that the fine particles can fall through the material layer and be discharged through the sieve holes, and the particles stuck in the sieve ho...
