Description
Technical field
The utility model relates to a kind of vibratory sieve.
Background technology
Vibratory sieve is a kind of equipment of common screening material, the operation principle of various vibratory sieves is similar, as a kind of ZS series linear vibrating screen commonly used is to use the motor synchronizing vibration principle, adopt vibrating motor as vibration source, helical spring is as shock absorber and high abrasion woven screen, off-centre compresses advanced technologies such as sealing, have long, characteristics such as noise is low, screening efficiency height of life-span, be fit to the efficient screening with sintering deposit, natural ore deposit, coke and powder and granule shape material, be widely used in industries such as metallurgy, mine, coke, building materials.
ZS series linear vibrating screen be one with screen box, the vibrator moving part is a quality, with the helical spring is flexible member, with vibrating motor is the screening plant of the forced vibration system of exciting mechanism, two vibrating motor eccentric blocks oppositely rotate at a high speed and produce powerful centrifugal force, thereby force screen box to do continuous straight-line oscillation campaign.It is power that material moves with this, makes continuous horizontal rectilinear motion on compass screen surface, layering when throwing, and the segment distance that advances forward after throwing sees through compass screen surface with granular size when falling, and has finished the classification process of material again and again like this.
When carrying out the screen cloth maintenance and changing, the operator must stand in the top that screen cloth has steel plate to support, and can not step down in the hanging part of screen cloth.Dismounting must be unclamped the tensioning plate bolt (totally 64) on the screen cloth side plate earlier during screen cloth, and then unclamps screen cloth hold-down bolt (totally 11 and three upper cover plates and go out 30+48+36+20=134 altogether of stub bar).When screen cloth was installed, necessary elder generation with screen cloth tensioning just, pressed press strip with tensioning plate then, and fastening hold-down bolt tightens up the tension bar bolt again.
In actual production, since use the feed particles form mostly be the faller gill shape cause screen cloth to stop up and spoilage quite high, the maintenance of screen cloth and replacing are quite time-consuming, every vibratory sieve generally needs 4 personal works just can finish in 5 hours approximately, not only bad for continuous production, increased processing cost and had certain danger.
The utility model content
The technical problems to be solved in the utility model is that the screen cloth that overcomes vibratory sieve of the prior art is changed the deficiency that bothers, and a kind of vibratory sieve that is convenient for changing screen cloth is provided.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Vibratory sieve comprises housing, screen cloth, discharge barrel, it is characterized in that discharge barrel and housing are hinged, the C type reinforcement plate that is used for fixing screen cloth is installed in the housing, also include compression beam, be provided with first spring between compression beam and the screen cloth, compression beam one end and housing flexibly connect, and the other end is between two limiting plates, the elastic compression parts also are installed on the housing, and the elastic compression parts are positioned at the top of compression beam near discharge barrel one end.
Wherein, described compression beam is hinged by hinge seat and bearing pin and housing away from an end of discharge barrel.
Wherein, described elastic compression parts comprise the convex shape push rod, sleeve, and the nut and second spring, sleeve has the external screw thread that cooperates with nut, and nut is fixed on the housing, and second spring is arranged in the sleeve and second spring, one end is fixed on the push rod.
Wherein, described C type reinforcement plate is fixed by nuts and bolt, and C type reinforcement plate is fixedlyed connected with bolt one end.
Wherein, described screen end has the corner of matching with C type reinforcement plate.
Wherein, described first spring, one end is fixed on the walking beam.
The beneficial effects of the utility model are: 1, compare with original equipment to significantly reduce and change the screen cloth required time
Its replacing screen cloth required time ratio is about 5 hours before and after the equipment improvement: 1 hour, the staffing ratio was 4 people: 2 people are ensureing the successional production cost that reduced simultaneously of production;
2, compare the danger that has reduced maintenance, changed screen cloth with original equipment
Before the equipment improvement, in order to save the time of maintenance, replacing screen cloth, can only pierce the internal body operation by personnel, it highly only is about 30cm, not only operation inconvenience, and also greatly dangerous.
After the improvement, only need screen cloth is extracted out from discharge barrel, greatly reduce danger.

Fig. 2 is the enclosure interior vertical view;
Fig. 3 is a C type reinforcement plate scheme of installation;
Fig. 4 is elastic compression modular construction and scheme of installation.
The specific embodiment
Referring to Fig. 1-Fig. 4, vibratory sieve comprises housing 1, screen cloth 2, discharge barrel 3, discharge barrel 3 is hinged with housing 1, and the C type reinforcement plate 4 that is used for fixing screen cloth 2 is installed in the housing 1, C type reinforcement plate 4 is fixing by second nut 15 and bolt 16, C type reinforcement plate 4 is fixedlyed connected with bolt 16 1 ends, and there is the corner 17 of matching with C type reinforcement plate 4 screen cloth 2 ends, also include compression beam 5, being provided with first spring, 6, the first springs, 6 one ends between compression beam 5 and the screen cloth 2 is fixed on the walking beam 5.Compression beam 5 is hinged with housing 1 by hinge seat 7 and bearing pin 8 away from an end of discharge barrel 3, the other end is between two limiting plates 9, limiting plate 9 is used to prevent that compression beam 5 from rocking, elastic compression parts 10 also are installed on the housing 1, elastic compression parts 10 are positioned at the top of compression beam 5 near discharge barrel 3 one ends, elastic compression parts 10 comprise convex shape push rod 11, sleeve 12, first nut 13 and second spring 14, sleeve 12 has the external screw thread that cooperates with first nut 13, sleeve 12 1 ends have circular hole, first nut 13 is fixed on the housing 1, the 3rd nut 18 can increase the pretightning force to sleeve 12, and second spring 14 is arranged in the sleeve 12 and second spring, 14 1 ends are fixed on the push rod 11, spring diameter greater than the push rod upper diameter less than Circularhole diameter, push rod 11 1 ends pass second spring and can pass in circular hole, by turn sleeve 12, compressible or stretch out second spring, thus increase or reduce the pressure of 11 pairs of compression beam of push rod.
When maintenance or replacing screen cloth 2, earlier discharge barrel 3 is upwards dug, remove the pressure of 10 pairs of compression beam 5 of elastic compression parts, second nut 15 is threaded to bolt 16 afterbodys, then 16 bolts are inwardly pushed away the bed knife that to remove 4 pairs of screen clothes of C type reinforcement plate behind about 30mm, after again compression beam 5 upwards being lifted about 120mm, screen cloth 2 is extracted out from discharge barrel is whole, carried out getting final product when more renewing screen cloth by above-mentioned steps one by one on the contrary.
