Spiral type spring vibration screening equipment

Abstract

The invention discloses spiral type spring vibration screening equipment which comprises a spiral type steel wire screen used for screening materials, a trough with fixed vibration frequency and a vibrating motor. According to the spiral steel wire screen, two adjacent spiral steel wires are connected in a 30-degree to 60-degree crispened mode to form stereoscopic meshes, the four edges of the stereoscopic meshes form two grooves in a two-up and two-down mode, identical spiral distances are formed by the spiral steel wires in the axial direction, the axial spiral distances and the size of the stereoscopic meshes can be designed according to screening demands, and one or more layers of spiral type steel wire screens are arranged in the middle of the trough. The spiral type spring vibration screening equipment can effectively improve the one-time passing rate of materials in the screening process, multiple times of vibration in the material separating process is reduced, and thus the separating effect and flow stability can be ensured.

Description

technical field [0001] The invention relates to a spiral spring vibrating screening device, in particular to a screen mesh formed by mutual hooking of spiral steel wires, which is used for screening / separating materials of different volumes, and belongs to material separation equipment. Background technique [0002] In the field of silk production, vibrating screens are generally used to screen materials with different volumes. Generally, rocker vibrating screens and shrapnel vibrating screens are used in vibrating mechanisms. The disadvantage is that the amplitude is large and the frequency is small, and the materials are screened before they are completely separated. As a conveying mechanism, it is transported to the next mechanism. The structure of the sieve surface is relatively rigid, with circular sieve holes and square sieve holes.

Problems solved by technology

[0002] In the field of silk production, vibrating screens are generally used to screen materials with different volumes. Generally, rocker vibrating screens and shrapnel vibrating screens are used in vibrating mechanisms. The disadvantage is that the amplitude is large and the frequency is small, and the materials are screened before they are completely separated. As a conveying mechanism, it is transported to the next mechanism. The structure of the screen surface is relatively rigid, with circular sieve holes and square sieve holes.

Among the two, the separation rate of the circular screen is the lowest, mainly because the hole spacing is affected by the processing and the strength of the plate, the number of meshes becomes smaller, and the material passing rate becomes lower; Compared with the former, it has improved, but it is an increase in the one-time pass rate, and the continuous production is far from meeting the requirements

The specifications of the screen are produced by the manufacturer's standard parts. Generally, the wire diameters of the warp and weft are relatively thin. Under the influence of the accumulation of materials and vibration, there will be different degrees of deformation. When the material passes through the square screen holes, it will also produce Hanging silk phenomenon, after the end of production, it is necessary to clean the mesh affected by the hanging silk phenomenon, which becomes smaller or blocked. Different materials need to replace the screen mesh tediously, and the separation rate of the silk flakes becomes low during the production process, and the material accumulates on the screen mesh It can't meet the current industrial requirements at all.
