A suspension double-layer screening machine mainly solves the problems of an existing screening machine that materials are easily plugged, screening amount is small, and screening level is not high. The screening machine comprises a screening body 14, the upper end of a support 12 is provided with a connection screening body 14 of a front sling 8 and a rear sling 5, the screening body 14 is provided with a feeding port 6, the upper portion and the lower portion of the screening body are respectively connected with an upper-layer composite screen 7 and a lower-layer composite screen 13, three discharging ports are arranged at the front end of the screening body 14, the composite screen is composed of a material screen 15 on an upper layer, an elastic ball screen 17 on a lower layer and an elastic ball 16 inside the elastic ball screen 17, a mesh hole of the elastic ball screen 17 is larger than that of the material screen 15, but smaller than the diameter of the elastic ball 16, height of each elastic ball screen 17 basket for containing the elastic ball 16 is two times of diameter of the elastic ball 16, the rear portion of the screening body 14 is connected with an eccentric shaft 3 through a pull rod 4, and the eccentric shaft 3 is in transmission connection with a belt 2 of a motor. The suspension double-layer screening machine has the advantages of being large in screening amount, not prone to plugging, and high in screening level.

Description

A kind of suspension double deck screen extension set

Technical field

The utility model relates to the classification material screening equipment, particularly a kind of suspension double deck screen extension set of granule materials gradation sizing.

Background technology

In existing production technology, screening machine is widely used in grain. feed. and flour. the multiple industry such as chemical industry, generally adopt the reciprocating screen extension set to come classifying granular material, the reciprocating screen extension set is that the cam that uses the sieve nest parallel direction to arrange rotates, so that sieve nest carries out reciprocating, thereby impel granular material to do parallel motion along sieve, simultaneously under the effect of self gravitation, pass through sieve, finish screening work, this screening machine granule materials is to pass through sieve by gravity, and particle easily is blocked in the sieve mesh, and the screening amount is little, output is not high, and the screening rank is not high.

Summary of the invention

Easily be blocked in the sieve mesh in order to solve existing screening machine material particles, the screening amount is little, output is not high, the not high problem of screening rank the utility model proposes a kind of suspension double deck screen extension set, by changing the movement locus of sieve, make sieve from original reciprocal action parallel with sieve, be improved to sieve nest and do circle, three different motion districts of ellipse and linear reciprocation are able to fast fully automatic classification, thereby greatly improved classification output, reached best screening effect, simultaneously, by the marble structure of composite screen, make material be difficult for being blocked in and shine on the net, better by by sieve, adopt simultaneously double-deck screening, improve the material screening rank.

The technical solution of the utility model is: this suspension double deck screen extension set comprises support, there is front hoist cable the support upper end and is connected hoist cable connection sieve nest, charging aperture is arranged on the sieve nest, the sieve nest upper and lower is connected with respectively upper strata composite screen and lower floor's composite screen, the sieve nest front end has respectively front discharging opening, middle discharging opening and rear discharging opening, composite screen is by the material screen on upper strata, the marble of the marble sieve of lower floor and marble sieve the inside form, the mesh of marble sieve is than the large of material screen but less than the marble diameter, each height that holds the marble sieve basket of marble should be the twice of marble diameter, the sieve nest rear portion connects eccentric shaft by pull bar, and eccentric shaft and motor have belt transmission.

The utlity model has following beneficial effect: by changing the movement locus of sieve, make sieve be improved to sieve nest and do circle, three different motion districts of ellipse and linear reciprocation, be able to fast abundant automatic classification, thereby greatly improved classification output, reached best screening effect, simultaneously, by the marble structure of composite screen, make material be difficult for being blocked in and shine on the net, better by passing through sieve, adopt simultaneously double-deck screening, improve the material screening rank, qualified material particles enters above the second layer sieve, material less than the qualified material specification enters second layer sieve bottom, qualified material is transported by discharging opening, has guaranteed the qualification rate of material particles, and it is large that this a kind of suspension double deck screen extension set has the screening amount, be difficult for stopping up the high characteristics of screening rank.

Description of drawings:

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is I place zoomed-in views of accompanying drawing 1.

Among the figure 1, motor; 2, belt; 3, eccentric shaft; 4, pull bar; 5, rear hoist cable; 6, charging aperture; 7, the upper strata composite screen; 8, front hoist cable; 9, front discharging opening; 10, middle discharging opening; 11, rear discharging opening; 12, support; 13, lower floor's composite screen; 14, sieve nest; 15 material screens; 16, marble; 17, the marble sieve.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1 in conjunction with shown in Figure 2, this suspension double deck screen extension set comprises sieve nest 14, there is front hoist cable 8 support 12 upper ends and is connected hoist cable 5 connection sieve nests 14, charging aperture 6 is arranged on the sieve nest 14, sieve nest 14 upper and lowers are connected with respectively upper strata composite screen 7 and lower floor's composite screen 13, sieve nest 14 front ends have respectively front discharging opening 9, middle discharging opening 10 and rear discharging opening 11, composite screen is by the material screen 15 on upper strata, the marble 16 that the marble sieve 17 of lower floor and marble sieve 17 the insides form, the mesh of marble sieve 17 is than the large of material screen 15 but less than marble 16 diameters, each height that holds 17 baskets of the marble sieves of marble 16 should be the twice of marble 16 diameters, when feed blocking during at the material screen cloth, because the motion of sieve nest, marble sieve the marble 16 motion collision material screens 15 of 17 the insides, make material screen 15 produce vibration, material comes off, sieve is difficult for stopping up, sieve nest 14 rear portions connect eccentric shaft 3 by pull bar 4, eccentric shaft 3 has belt 2 transmissions with motor 1, because sieve nest 14 suspends, rotation along with eccentric shaft 3, sieve nest 14 rear portions move in a circle, elliptic motion is done at sieve nest 14 middle parts, the front portion moves reciprocatingly, material is able to fast fully automatic classification, thereby has greatly improved classification output, has reached best screening effect, simultaneously, by the marble structure of composite screen, make material be difficult for being blocked in and shine on the net, better by passing through sieve, adopt simultaneously double-deck screening, improve the material screening rank.
