Abstract
The utility model belongs to screen surface technique used by sieving equipment. The utility model is mainly composed of multiple spiral springs and spacing plates, wherein, the thread pitch of the spiral springs is equal to or approximately equal to designed sizes of screen meshes, and multiple spiral springs are longitudinally or transversally arranged; the spacing plates which are parallel to the helical springs are arranged at the both sides of the helical springs, and the spacing plates are transversally or longitudinally arranged at the bottom of the spiral springs. When the spring screen surface of the utility model is arranged on a vibration screen for sieving, the springs generate local large-amplitude vibration; therefore, the utility model has very high screen penetrating rate for sticky, wet and fine material, and holes are not easy to clog. The utility model is especially suitable for depth sieving for the finer granularity of coal with the granularity of three to six millimeters, etc.
Description
The utility model belongs to the used compass screen surface technology of screening plant, specifically proposes a kind of screening plant special purpose spring compass screen surface.
The compass screen surface that screening plant uses has woven screen now, and structure is the net that metal or nonmetal wire are woven into; The wedge wire screen plate is the compass screen surface that is made of parallel moulding rod; The punching sieve plate is a punching press pass gained on steel plate, also has the compass screen surface of being made by rubber or polyurethane.Above-mentioned all kinds of compass screen surface is when the screening of material that carries out viscous material, high humidity and fine granular materials, because there is not vibration in compass screen surface itself or vibrates very little, therefore be easy to stoppage phenomenon, the carrying out of the normal screening of influence, also have a kind of rod compass screen surface, compass screen surface is made of shaped steel, though big oscillation intensity is arranged when screening, be difficult for plug-hole, but its structure makes it can not carry out more fine-grained classification.
The purpose of this utility model promptly is to propose a kind of screening plant special purpose spring compass screen surface, it is bigger to make it self produce vibration and amplitude and oscillation intensity when sieving, make its suitable sticking, wet, thin material screening, thereby overcome existing compass screen surface, the existing defective of mesh structure.
The utility model is finished the technical scheme that its invention task takes: this compass screen surface mainly is made of many helical springs and limiting plate, the many vertical or horizontal arrangement settings of helical spring, and limiting plate and helical spring be arranged in parallel and are positioned at helical spring both sides.
Limiting plate laterally or vertically is arranged on the helical spring bottom.
Helical spring pitch equals the designed screen size of compass screen surface.
The spring compass screen surface that the utility model proposes has good elasticity, be installed on when sieving on the vibratory sieve, spring produces local large-amplitude vibration, oscillation intensity is much larger than 5 times of acceleration of gravity, for sticking, wet, thin material very high screening percentage is arranged, and be difficult for plug-hole, be particularly suitable for more fine-grained deep screenings such as coal 3mm, 6mm.Experimental results show that, the utility model compass screen surface be solve that coal is sticking, wet, one of the preferred structure of a dusting cover branch difficult problem, the flip-flow screening machine of the vibratory sieve that adopts this spring compass screen surface and external import (it can be used for the deep screening of coal, but spare part and consumptive material costliness) is compared, and is cheap and for ease of maintenaince.Compare reliable in structure, long service life (the piano wire screen string silk life-span has only several days or tens days) with piano wire screen.
Embodiment:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the A-A profile of Fig. 1.
The embodiment that provides with reference to accompanying drawing is further specified its structure:
Shown in accompanying drawing 1,2, the utility model compass screen surface is made of many helical springs 1 and limiting plate 2, and many helical springs 1 are vertically arranged on compass screen surface and are provided with among this embodiment, and two ends are fixed on the end face steel plate 4, and 3 is set bolt or other fixture.Limiting plate 2 vertically and helical spring 1 be set in parallel in helical spring both sides.Also but several limiting plates of horizontally set 2, and limiting plate 2 are arranged on the bottom position of helical spring 1.Helical spring 1 can be metal material and makes, and also can adopt other material.Limiting plate 2 adopts steel plate or other composite.
The pitch 1 of helical spring 1 equals the screen size of compass screen surface design, also pitch 1 design of helical spring 1 can be approximately equal to screen size.
Spacing between spacing between the helical spring 1 or helical spring 1 and the left and right sides limiting plate 2 is approximately equal to helical spring pitch, and left and right sides limiting plate and bottom limiting plate are all in order to limit helical spring amplitude.
As shown in Figure 2, helical spring 1 designs not on same plane with limiting plate 2, also can design on a same level, mainly determines according to material handling amount and material characteristic.
