Abstract
The utility model discloses a linear screen plate capable of being tensioned and belongs to the field of vibrating screening machines. The defects of low aperture ratio, poorer elasticity, easiness in hole blockage, and the like, of a screen plate, are solved. The linear screen plate mainly comprises a screen plate frame and linear screen strips, wherein the screen plate frame consists of two side frame bodies and a screen strip tensioning device between the two side frame bodies; screen strip positioning hooks with equal intervals are fixed on the side frame bodies according to requirements on the size of screen holes; linear screen strip end part locking components are arranged on the inner sides of the end parts of the side frame bodies; ends of the linear screen strips are locked through the locking components and are sequentially and repeatedly wound on the positioning hooks on the two side frame bodies; and the other ends of the linear screen strips are also locked through the locking components. The linear screen strips are steel wire ropes or polyurethane strips containing the steel wire ropes. The screen plate has the characteristics of high aperture ratio and elasticity, capability of generating secondary vibration, no hole blockage, simple structure and convenience in tensioning, and is particularly applied to various vibration screens which are used for screening wet fine particles.
Description
Technical field
The utility model belongs to the vibration screening machinery field, and high, the good springiness of the percent opening that mainly relates to sieve plate is applicable to the linear sieve plate of securable formula that sticking wet fine granular materials sieves.
Background technology
Sieve plate is the main screening component of vibratory sieve, and its performance directly influences the disposal ability of vibratory sieve and the screening effect of material.For the screening of sticking wet fine granular materials, be the difficult problem that screening industry urgent need solves at present.Because sticking wet fine granular materials under the effect of moisture and clay, bonds agglomerating each other or attached on the screen cloth, very difficult loose, tiny sieve aperture can stop up gradually, and the effective sifting area of vibratory sieve is reduced, cause screening process to worsen, screening efficiency sharply descends.Sieve the sieve plate of this material at present, like elastic rod sieve plate, motion bar sieve plate, broach sieve plate, self-cleaning rod sieve plate and notch cuttype sieve plate etc.The drawback of these sieve plates is that percent opening is low, sieve plate lacks elasticity, has produced not secondary vibration, is prone to plug-hole, and the sieve plate screen size can't be made very for a short time." the linear sieve plate of securable formula " (number of patent application: invention 201110223369.5) preferably resolves this problem, and this invention has been formed the overall screen plate framework through left and right sides sieve plate framework and tensioning jockey; The sieve plate framework is provided with the grating built-in beam, and linear grating back and forth is fixed on the grating built-in beam at sieve plate framework two ends successively; The centre of grating places on the grating brace summer, and two ends are through locking member locking.This linearity sieve plate is through producing and using proof, and the manufacturing cost of this linearity sieve plate is higher, and because linear grating receives the restriction of grating brace summer, has weakened the elasticity of linear grating.
Summary of the invention
The purpose of the utility model provides the linear sieve plate of a kind of securable formula, the percent opening of this sieve plate is high, elasticity special good, can produce secondary vibration, have simple in structurely simultaneously, tensioning is characteristics easily.
The utility model is realized through following measure, mainly is made up of sieve plate framework and linear grating, it is characterized in that: the sieve plate framework is made up of two frame bodies and the grating tensioning apparatus between two frame bodies; Be fixed with the grating location hook of equidistant from distance on the frame body by the screen size requirement, be provided with linear grating end locking member in the inboard of frame end of body; One end of linear grating back and forth is wrapped on the location hook of two frame bodies through locking member locking successively, and the other end is also through locking member locking.The material of linear grating is steel wire rope or the polyurethane strip that includes steel wire rope.
According to the needs of different vibratory sieves with the screening material, the grating tensioning apparatus of forming the sieve plate framework has 2～5, and each grating tensioning apparatus mainly is made up of abutment sleeve, support bar, adjustment nut and locking nut; Support bar one end is processed with one section screw thread and one section fitted shaft, and the other end is fixed therein on the frame body, and abutment sleeve is fixed on another frame body by the position correspondence of support bar.The frame body of sieve plate framework is by rectangular steel pipe or seamless steel pipe manufacturing.The end locking member is through U bolt folder or rope cramp fixed linear grating.
The beneficial effect of the utility model is, the sieve plate framework of the linear sieve plate of securable formula is made up of two frame bodies and grating tensioning apparatus, and the structure that makes sieve plate is compactness more, and the installation of linear grating is simpler, the tensioning of linear grating and easy to adjust reliably.The percent opening of sieve plate can reach more than 60%, and the size of classification sieve aperture can be fabricated into 3～6 millimeters.Simple frame body has replaced the left and right sides sieve plate framework of prior art, makes installation, tensioning and the convenient disassembly of linear grating.Reduce grating brace summer of the prior art simultaneously, increased the elasticity of linear grating.This sieve plate have percent opening height, elasticity spy good, can produce not plug-hole of secondary vibration, have simple in structure and tensioning characteristics easily simultaneously.Be particularly suitable for of the screening of various vibratory sieves to sticking wet fine granular materials.
