Description

A kind of separator

Technical field:

The utility model relates to a kind of separation equipment, particularly a kind of separator.

Background technology:

The direction of vibration of the sieve of existing vibratory sieve is identical with the outflow direction of material, and the shortcoming of the direction of motion of this sieve is, material is short in the time of staying of compass screen surface, and sifting net rate is lower; In addition, the vibrator of this sieve carries out exciting to frame, and consumed energy is more.

Summary of the invention:

The purpose of the utility model provides the high a kind of separator of a kind of sifting net rate.The technical scheme of the utility model is; Comprise screen frame and motor, it is characterized in that: screen frame is suspended on respectively in the framework of the support left and right sides, and said framework is the square frame that pillar and transverse slat are formed; With stringer board former and later two described square frames are formed framework; The lower end of described framework and four supporting legs are hinged, and the lower end and the support of these four supporting legs are hinged, and the left and right side of said screen frame respectively is provided with a forward and backward suspension rod; The upper end of each suspension rod respectively with the pillar inner surface of framework left and right side on link plate hinged; The lower end of each suspension rod respectively with the outer surface of the left and right side plate of screen frame on flange hinged, respectively be provided with on the inner surface of left and right four pillars in the front and back of framework one respectively with the left and right side plate of screen frame on the relative impact block of flange, gapped between the flange on impact block and the screen frame side plate; Belt pulley on the eccentric shaft is relative with the motor pulley on the support, is arranged with crank on this eccentric shaft, and the outer end and the framework of crank are hinged, and the crank that wherein is hinged with a left side or correct frame is at least two.The said crank that is hinged with framework; Wherein overlap at the center of a body side frame therewith with the framework of the eccentric shaft one side effect of the crank center of making a concerted effort that is hinged, the center overlaps at the center of opposite side framework therewith and the effect of the crank that is hinged with the framework of eccentric shaft opposite side is made a concerted effort.The utility model and prior art relatively have the low remarkable advantage of the high tool consumed energy of screening efficiency.

Description of drawings:

Fig. 1 is the front view of the utility model, and Fig. 2 is the side view of Fig. 1, Fig. 3 be the A of Fig. 1 to view, Fig. 4 is the suspended structure sketch map of screen frame and frame, Fig. 5 is the vertical view of Fig. 4.

The specific embodiment:

The reciprocating direction of the utility model employing screen frame and the flow direction of material discharging are perpendicular, and the outflow direction of material relies on compass screen surface to be obliquely installed the compass screen surface realization from charging aperture to discharging opening.The material of this mode is done back and forth horizontal motion on compass screen surface, the charging aperture from compass screen surface moves towards discharge end along slanted screen simultaneously, and the screening time of material on compass screen surface has obtained prolongation, thereby has improved sifting net rate.

As an embodiment; Be provided with a support 10 at the middle part of support 1, the rear and front end of eccentric shaft 12 is supported in the dead eye on the above-mentioned support, and the belt pulley on this eccentric shaft is connected with the belt pulley of motor 9 on being fixed on support 1 through belt; Eccentric shaft connects four cranks 11; Wherein the framework 3 in the outer end of former and later two cranks and support left side is hinged, between above-mentioned forward and backward crank, is provided with two cranks in addition, and the framework 3 on the external end head of this two crank and support right side is hinged; Consider the requirement of left and right crank effect equilibrium of forces, all should working as with joint efforts of left side or right side crank acts on the frame center place that is connected.The structure of said left and right framework is; Front end left and right respectively is provided with a pillar 13 in the left side of support, and the rear end in support left side left and right also is provided with two relative pillars 13, and the top and bottom of left and right pillar are provided with cross connecting plate; The top and bottom of this left and right pillar and middle part respectively are provided with vertical connecting plate 14; Make it to form a general frame 3, vertically connecting plate 14 is hinged therewith in the outer end of said crank, and the lower end of said each pillar is hinged with supporting leg 2 respectively; The lower end of each supporting leg is hinged with support respectively, and left side screen frame 8 hangs on respectively in the left and right framework with right side screen frame 8.Suspended structure is, the front and rear portions of the left and right side plate of screen frame respectively is provided with overhanging flange 6, and the top of the left pillar of framework respectively is provided with a link plate of inwardly stretching 7, and the top and bottom of suspension rod 5 are hinged with above-mentioned flange and link plate respectively.Realize the gradient of compass screen surface through the difference in height of suspension rod before and after the screen frame.Respectively be provided with on the inner surface of left and right vertical side plate of framework two impact blocks 4 respectively with the left and right side plate of screen frame on overhanging flange 6 relative.For the compass screen surface that makes suspended screen laterally is being the level of state, the bottom of suspension rod is that the screwed hole of the cylinder on the flange upper surface overhanging on screw thread cylinder and the screen frame matches.

When separator need sieve the material of multiple different-grain diameter simultaneously, can hang the screen frame of a plurality of different-grain diameters at the differing heights of screen frame (unit), the particle diameter of top sieve is maximum, and particle diameter successively reduces from top to bottom.The suspended structure of this multi-deck screen is identical; Just the front and back size of the left and right pillar in the screen frame (unit) should strengthen; Make the boatswain chair of each layer sieve that installing space arranged, another kind of mode is a not increased in size of pillar, but increases a tilting gripper shoe 15; At this moment, link plate and impact block all are located on this tilting gripper shoe.(referring to Fig. 2)

The operating principle of the utility model suspended screen is, motor rotates and drives the eccentric shaft rotation, and crank driving left and right framework is made left and right traverse motion, is suspended on screen frame in the framework along with screen frame (unit) is done left and right reciprocating motion.It is relative that the overhanging plate of impact block and screen frame is set on the pillar of framework, and this impact block bump screen frame makes its motion, facts have proved that effect is very good.The bump of the impact block also cleaning effect to screen cloth is good especially, and this clear net effect is more much better than the effect of existing grid cleaner structure, and it is relevant with the gap length between impact block and screen frame to net effect clearly, generally about 2mm.
