Description

A kind of multi-stage oscillating screen

Technical field

The utility model relates to raw material screening technical field, is specially a kind of multi-stage oscillating screen.

Background technology

Before the original coal cinder of use carries out coking, need to screen coal cinder, vibratory sieve conventional at present only has one deck sieve plate, primary screening can only be carried out to coal cinder, the coal cinder filtered out is very coarse, many times can not meet the requirement of processing further, it is very inconvenient to bring to coal cinder screening operation, the device of multistage screening a kind of demand can be just become successively so a kind of, but current existing multistage sieve adopts one pole to sieve separate power input more, and the motor rotor eccentric that adopts provides dither more, although have high frequency, but amplitude is less, be not suitable for the raw material larger to some weight to screen.

Utility model content

The purpose of this utility model is to provide a kind of multi-stage oscillating screen, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of multi-stage oscillating screen, comprise housing, connecting rod, screen cloth and screen frame, described screen cloth is fixedly connected with by screw with screen frame, described screen frame comprises frame body, the first half welding of described frame body both sides is picked up the ears, and frame body top welding ear seat, pick up the ears on described to have through hole with ear seating face, pick up the ears under described housing cavity surface soldered, pick up the ears under described to weld with polished rod, described polished rod pick up the ears from above surface through hole pass, and polished rod outside suit hard spring, described hard spring one end with on pick up the ears to be connected the other end with under pick up the ears to be connected, described connecting rod one end is connected by the through hole of bearing pin and ear seating face, the described connecting rod other end and bent axle are connected, described crankshaft two end is connected with enclosure interior support by bearing.

Preferably, described polished rod and on pick up the ears between, all install lining additional between connecting rod and bearing pin and between connecting rod and bent axle.

Preferably, described bent axle upper end is input and is connected with external input device by belt.

Preferably, described bent axle at least comprises four pitman shafts and the horizontal sextant angle of adjacent two pitman shafts is 120 °, and described screen frame quantity is consistent with pitman shaft.

Compared with prior art, the beneficial effects of the utility model are: this new structure is traditional monopole sieve comparatively, add screening progression, and the screen cloth of next stage is more intensive than upper level screen cloth, realize multistage screening to carry out and the effect of each pole is different simultaneously, contribute to increasing work efficiency, compare existing multistage sieve, this device eliminates traditional eccentric motor vibrating device and one pole separate power input unit, adopt the crankshaft connecting rod system that multistage power inputs simultaneously, reduce energy waste and increase effective displacement of screen cloth, solving screen cloth amplitude in the past not cannot to the problem of the larger raw material screening of weight.

Fig. 2 is the utility model screen frame structural representation;

Fig. 3 on to pick up the ears partly cut-away's schematic diagram.

In figure: 1 housing, 2 bent axles, 3 connecting rods, 4 bearing pins, 5 screen clothes, 6 screen frames, 601 frame bodies, 602 are picked up the ears, 603 ear seats, 7 polished rods, 8 hard springs, pick up the ears for 9 times, 10 linings.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1-3, the utility model provides a kind of technical scheme: a kind of multi-stage oscillating screen, comprise housing 1, connecting rod 3, screen cloth 5 and screen frame 6, screen cloth 5 is fixedly connected with by screw with screen frame 6, screen frame 6 comprises frame body 601, the first half welding of frame body 601 both sides picks up the ears 602, and frame body 601 top welding ear seat 603, on pick up the ears 602 and ear seat 603 surface have through hole, 9 are picked up the ears under the welding of housing 1 surface of internal cavity, under pick up the ears 9 to weld with polished rod 7, pick up the ears from the above through hole on 602 surfaces of polished rod 7 passes, and polished rod 7 outside suit hard spring 8, hard spring 8 one end with on pick up the ears 602 be connected the other end with under pick up the ears 9 to be connected, hard spring 8 can make screen frame 6 have certain kinetic energy when backhaul, promote bent axle 2 to do manual work simultaneously, make bent axle 2 each portion uniform force, connecting rod 3 one end is connected by the through hole of bearing pin 4 with ear seat 603 surface, connecting rod 3 other end and bent axle 2 are connected, bent axle 2 two ends are connected with housing 1 internal stent by bearing, polished rod 7 and on pick up the ears between 602, lining 10 is all installed additional between connecting rod 3 and bearing pin 4 and between connecting rod 3 and bent axle 2, avoid scrapping because wearing and tearing cause equipment precision to decline between each parts, bent axle 2 upper end is input and is connected with external input device by belt, belt transmission has good shock-absorbing and overload protective function, bent axle 2 at least comprises four pitman shafts and the horizontal sextant angle of adjacent two pitman shafts is 120 °, ensure that each screen cloth 5 has the speed of different directions in the same moment, screen frame 6 quantity is consistent with pitman shaft.
