A screen plate framework is composed of a left screen plate framework and a right screen plate framework; the left screen plate framework is fastened with the right screen plate framework by a tensioning connecting device; screen strip fixing beams are arranged at two ends of the screen plate framework; a screen strip supporting beam is arranged in the middle part of the screen plate framework; a support positioning strip is arranged on the screen strip supporting beam; screen strips are linear screen strips; one end of each linear screen strip is locked by a locking piece; the linear screen strips are fixed on the screen strip fixing beams at two ends of the screen plate framework in a reciprocating manner in sequence; the middle of linear screen strips are arranged on the support positioning strip of the screen strip supporting beam; and the other end of each linear screen strip is locked by a locking piece. The tensioning type linear screen plate has the characteristics of high opening rate, good elasticity, high percent through screen, no hole blocking and convenience for tensioning, replacing and maintenance. Particularly, the tensioning type linear screen plate is applicable to screening sticky and wet fine grain materials.
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, is difficult to loose.Tiny sieve aperture can stop up gradually, and the effective sifting area of vibratory sieve is reduced, and causes screening process to worsen, and screening efficiency sharply descends.The present sieve plate of this material of screening, like elastic rod sieve plate, motion bar sieve plate, broach sieve plate, self-cleaning rod sieve plate and notch cuttype sieve plate etc., all exist sieve aperture be difficult for too little, percent opening is low, the elasticity of sieve plate is relatively poor and shortcoming such as easy plug-hole.
Summary of the invention
The purpose of the utility model provides the linear sieve plate of a kind of securable formula, and the percent opening height of this sieve plate, good springiness, screening percentage height have tensioning, replacing and characteristics easy to maintenance simultaneously.
The utility model is realized through following measure.Mainly be made up of sieve plate framework, grating, grating support and tensioning jockey, it is characterized in that: the sieve plate framework is made up of left sieve plate framework and right sieve plate framework, and left and right sides sieve plate framework tightens together through the tensioning jockey; Be provided with the grating built-in beam at the two ends of sieve plate framework; In the middle part of sieve plate framework, be provided with the grating brace summer, the support positioning strip is housed above the grating brace summer; Described grating is linear grating, and an end of linear grating back and forth is fixed on the grating built-in beam at sieve plate framework two ends through locking member locking successively, and the centre places on the support positioning strip on the grating brace summer, and the other end is through locking member locking.
The tensioning jockey that connects left and right sides sieve plate framework is made up of tensioning bolt and the adjustment nut and the locking nut that are positioned on the sieve plate framework of the left and right sides; The screw thread at adjustment nut two ends is respectively left hand thread and right-handed thread.The grating built-in beam at sieve plate framework two ends is made up of pipe and a plurality of equidistant reference column that is arranged on the pipe, and linear grating back and forth is wrapped on pipe and the reference column successively.
For prolonging the service life of linear grating, the support positioning strip on the grating brace summer is to be made by nonmetal plastic material; Support on the positioning strip and be processed with equidistant translot, linear grating places in the translot; In order to guarantee that linear grating can tensioning, make the compass screen surface of formation smooth, the bottom of supporting the positioning strip translot is higher than the upper surface of the grating built-in beam at screen frame two ends.The material of linear grating is steel wire rope or the polyurethane strip that includes steel wire rope.A plurality of equidistant reference column on the pipe is processed with equidistant translot with supporting on the positioning strip, is that the requirement according to screen size and linear grating diameter is provided with.
The beneficial effect of the utility model is, adopts the linear grating sieve plate of tensioning, and the percent opening of sieve plate can reach more than 60%, and the size of classification sieve aperture can be fabricated into 3-6mm.The screw thread that connects the tensioning bolt of left and right sides sieve plate framework is respectively left hand thread and right-handed thread, and the tensioning degree of linear grating is adjusted by the adjustment nut.Percent opening with sieve plate is high, good springiness, and screening percentage is high, plug-hole not, tensioning, replacing and characteristics easy to maintenance.Be specially adapted to sieve sticking wet fine granular materials.
