Single-layer relaxation sieve type sieving equipment

Abstract

The invention belongs to the technical field of relaxation type sieving mechanical equipment, and particularly relates to single-layer relaxation sieve type sieving equipment. Additional vibrating bodies are fixedly connected with a main vibrating body through rubber block units; the rubber block units are fixed on a rigid bracket of the main vibrating body; the additional vibrating bodies consist of floating crossbeams and floating connecting rods which are connected with the floating crossbeams; polyurethane sieve plate fixing bases of sieve plates are arranged on the fixed crossbeams and the floating crossbeams; adjacent fixed crossbeams and floating crossbeams are connected through the polyurethane sieve plate fixing bases and the sieve plates; independent vibration sources which are connected through intermediate shafts are arranged on a left side plate and a right side plate of the main vibrating body respectively; intermediate shaft protection casing beams which are connected with the left side plate and the right side plate are arranged outside the intermediate shafts. The single-layer relaxation sieve type sieving equipment has the beneficial effects that relative movement between the main vibrating body and the additional vibrating bodies is realized, and the problem of low sieving efficiencies of sieve blocking holes, sieve bonding surfaces and the like in the sieving process of sticky and wet materials can be effectively solved.

Description

technical field [0001] The invention relates to the field of relaxation-type screening mechanical equipment, in particular to a single-layer relaxation-type screening equipment. Background technique [0002] The existing relaxation screen structure is a crank connecting rod structure. The rotation of the crankshaft drives the movement of the movable frame, which is generated by the relative movement of the main frame and drives the relaxation of the flexible sieve plate. However, the main frame of the screen machine with this structure does not vibrate. Comprehensive application has limitations. For example, if a double-layer screen machine is used, the upper screen surface is a traditional fixed screen surface, and the screening operation cannot be performed because the screen surface has no movement. Moreover, sticky and wet materials are prone to problems such as blocked screen holes and sticky screen surface during the screening process, which make the screening efficien...

Problems solved by technology

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a single-layer relaxation screen type screening equipment, which uses the principle of two-mass sub-resonance to realize the relative movement of the main vibrating body and the additional, which can effectively solve the problem of viscous and wet materials. During the screening process, the screen hole is blocked, the screen surface is sticky, etc., which make the screening efficiency low.
