Abstract
The invention discloses a tensioning type linear sieve plate belonging to the field of vibratory screening machinery and overcoming the defects of low aperture ratio, poorer elasticity, easiness in pore blockage and the like of the traditional sieve plate. A sieve plate frame comprises a left sieve plate frame and a right sieve plate frame which are fastened together through a tensioning connecting device; two ends of the sieve plate frame are provided with grating fixing beams; the middle of the sieve plate frame is provided with a grating supporting beam, and a supporting positioning strip is arranged on the grating supporting beam; and a grating is a linear grating, one end of the linear grating is locked through a locking member and sequentially fixed on the grating fixing beam at twoends of the sieve plate frame in a reciprocating manner, the middle of the linear grating is arranged on the supporting positioning strip on the grating supporting beam, and the other end of the linear grating is locked through the locking member. The sieve plate disclosed by the invention has the characteristics of high aperture ratio, good elasticity, high sieve-penetrating ratio, difficulty inpore blockage and convenience for tensioning, replacing and maintaining, and is especially suitable for sieving wet and sticky fine particular materials.
Description
Technical field
The invention belongs to the vibration screening machinery field, the percent opening that mainly relates to sieve plate is high, good springiness, is applicable to the Linear screen plate capable of being tensioned of sticking wet fine granular materials screening.
Background technology
Sieve plate is the main screening component of vibratory sieve, and its performance directly affects the disposal ability of vibratory sieve and the screening effect of material.For the screening of sticking wet fine granular materials, be screening industry urgent need to solve the problem at present.Because sticking wet fine granular materials under the effect of moisture and clay, mutually bonds agglomerating or is attached on the screen cloth, be 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, such as elastic rod sieve plate, sieve plate with detachable bar, sieve plate with comb teeth, self-cleaning bar screen 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 the shortcoming such as easy plug-hole.
Summary of the invention
The purpose of this invention is to provide a kind of Linear screen plate capable of being tensioned, the percent opening of this sieve plate is high, good springiness, screening percentage are high, has simultaneously tensioning, replacing and characteristics easy to maintenance.
The present invention is achieved by the following measures.Mainly be comprised of sieve plate framework, grating, grating support and tensioning jockey, it is characterized in that: the sieve plate framework is that left and right sides sieve plate framework tightens together by the tensioning jockey by left sieve plate framework and right sieve plate system framework; 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 supporting and location bar is housed above the grating brace summer; Described grating is linear grating, and an end of linear grating is locked by locking member, back and forth is fixed on successively on the grating built-in beam at sieve plate framework two ends, and the centre places on the supporting and location bar on the grating brace summer, and the other end is locked by locking member.
The tensioning jockey that connects left and right sides sieve plate framework forms by being positioned at tensioning bolt on the sieve plate framework of the left and right sides and adjusting nut and locking nut; The screw thread at adjusting nut two ends is respectively left hand thread and right-handed thread.The grating built-in beam at sieve plate framework two ends is comprised of pipe and a plurality of equidistant locating dowel that is arranged on the pipe, and linear grating back and forth is wrapped on pipe and the locating dowel successively.
For prolonging the service life of linear grating, the supporting and location bar on the grating brace summer is to be made by nonmetal plastic material; Be processed with equidistant translot on the supporting and location bar, 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 and location bar 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.Being processed with equidistant translot on a plurality of equidistant locating dowel on the pipe and the supporting and location bar, is to arrange according to the requirement of screen size and linear grating diameter.
The invention has the beneficial effects as follows, adopt the linear grating sieve plate of tensioning, 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 adjusting 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.
