Abstract
The utility model relates to a screen mesh device without hole clogging, which is composed of a screen frame, a separation screen face, a ball supporting net, a tension frame, a cleaning ball, etc. The utility model has the advantages that the reasonable structure of the utility model can ensure that the separation screen face is always below 5 % of hole clogging rate, the defects that the hole clogging rate of the original screen mesh is too high and manual cleaning is needed are overcome for making the operation more convenient and faster and for making more time and labour saved, the finishing yield and the classifying accuracy of grain finished products are increased, and the output and the grain finished product quality in the whole production process are ensured.
Description
The utility model relates to the sieve lattice device in the grain processing industry screening installation.
In the use of screening installations such as existing grain finished product arrangement and byproduct arrangement; because sieve lattice apparatus structure is unreasonable; especially the defective of the tensioning frame planform of ball impact motion is cleared up in decision; directly effect is stopped up in the cleaning of influence cleaning ball; make the sieve lattice large tracts of land sieve pore blockade phenomenon occur; and along with the time is cumulative; the sieve pore blockade rate rises gradually, even the sieve aperture that can occur more than 50% is blocked, causes effectiveness of classification low thus; the grain rank descends; influence economic benefit,, often need to shut down in order to improve effectiveness of classification; pull out the sieve lattice and carry out the labor cleaning; it is time-consuming to seem like this; effort, and influence output in the whole production flow process.
The purpose of this utility model all provide in the defective that overcomes prior art a kind of percentage of plugged hole low, need not the high not plug-hole sieve lattice device of labor cleaning, effectiveness of classification.
According to above-mentioned purpose, embodiment of the present utility model is: include a screen frame, the separation compass screen surface of densely covered sieve aperture and the holder net periphery of densely covered mesh are fixed with the upper and lower edge of screen frame respectively, the tensioning frame of layout is located to separate between compass screen surface and the holder net and forms a plurality of ball lattice in length and breadth, and be connected by tensioning double-screw bolt and screen frame are adjustable, be provided with the cleaning ball in the ball lattice, it is characterized in that described tensioning frame two side is symmetrical skew wall shape, the underrun plate is fixed with the holder net.
The utility model is owing to adopted technique scheme, cleaning ball bounce is of moderate size, the sieve lattice are remained be lower than 5% percentage of plugged hole, defectives such as the shut-down that caused so overcome that sieve pore blockade needs the labor cleaning, time-consuming, effort, make operation more convenient, more laborsaving, improved labor productivity, guaranteed that screen equipment has very high effectiveness of classification all the time, thereby improved the quality retaining of finished product grain, and can reach the class requirement of international trade grain, also for becoming the outlet of platform equipment to create advantage.
Description of drawings
Fig. 1 is the utility model general structure cutaway view.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A place enlarged drawing of Fig. 1.
Embodiment to the utility model further describes again below with reference to above-mentioned accompanying drawing.
Referring to Fig. 1-3, plug-hole sieve lattice device does not include the screen frame (7) that a timber is made, and a panel (1) is fixed with wood screw in the front side of screen frame, and panel has two handles (8), is drawer type.
The separation compass screen surface (3) of densely covered sieve aperture and the holder net (6) of densely covered mesh periphery are fixed with the upper and lower edge of screen frame respectively, after wherein separating compass screen surface and being placed on screen frame top, it is fixing that three edges are pushed down by timber press strip (2), and one edge, panel opposite is a discharging opening, does not seal.The holder net is fixed on shoulder place in the screen frame below.
Separate compass screen surface (3) and can be separation sieve plate, or by the screen cloth of braided steel wire by the steel plate punching processing, the THICKNESS CONTROL of wherein separating sieve plate between 0.5-0.9mm, the too thick percentage of plugged hole that can increase sieve aperture, too thin rigidity and the service life that can reduce sieve plate.
Holder net (6) mesh size is a per inch 2-3.5 order, is woven into concavo-convex structure, and fixing necessary reliable with screen frame around it, four limits must not have loosening after being tensioned.
The tensioning frame of layout (4) is located to separate between compass screen surface and the holder net and forms a plurality of ball lattice in length and breadth, and by being connected with screen frame is adjustable with the tensioning double-screw bolt (9) of its welding, it is fastening by nut (10) that rate of tension regulates the back.The tensioning frame two side is symmetrical skew wall shape, skew wall angle α=25 °-45 °, and α too conference blocks the cleaning ball, and too little cleaning ball impact bounce-back number of times reduces, and all can influence the effect of cleaning sieve aperture.Be welded after the steel plate punch forming of tensioning frame by thickness 1-3mm, the plate (11) of underrun welding is fixed with the holder net, and it is big that the rigidity of tensioning frame sidewall is wanted, and can not be out of shape during the collision of cleaning ball, and every ball lattice area is not more than 1500cm
2
Cleaning ball (5) is located in the ball lattice, and it is directly through getting Φ 22-Φ 30mm, every 200cm
2The ball lattice in must not be less than 1, make of rubber, must have enough distortion elasticity, hardness is Shore 55-60 degree, the cleaning ball should be controlled between the 3-6mm with the gap delta of separating compass screen surface.The purpose that the cleaning ball is set is to make it to clash into the ball lattice skew wall of tensioning frame in the equipment operation process, after the bounce-back of cleaning ball, the bump compass screen surface is produced perpendicular to the power of compass screen surface and the vibration of compass screen surface, both are in conjunction with the particle that embeds sieve aperture is deviate from, behind the bump compass screen surface bounce-back downwards and with the collision of holder net, the holder net makes the cleaning ball collision compass screen surface that rebounds once more again, clash into compass screen surface so repeatedly, thereby the sieve aperture of compass screen surface is not prematured by solids all the time, reaches percentage of plugged hole and be lower than 5% and improve the purpose of effectiveness of classification.
