Abstract
The invention discloses a vibrating screen which comprises a seal plate, a guide plate, a screen and a screen tensioning device, wherein the screen tensioning device is formed by two tensioning units, each tensioning unit is formed by a screen side plate, a pinch plate, a screw, a nut, a screen, support angle steel, and a transverse beam, each pinch plate and each screen side plate have the same length, each pinch plate is connected with each screen side plate in a fastened mode through each screw and each nut, each pinch plate enables each screen to be tightly tensioned on the support angle steel and each transverse beam, each screen side plate is provided with a maintenance hole, four corners of each maintenance hole are circular corners, the outer side of each maintenance hole is provided with a press cover, the split-type seal plate is arranged on the outer sides of the screen side plates, and the split-type seal plate is longitudinally arranged. According to the vibrating screen, stress of the screen tends to be uniform, service life is prolonged, and replacement of the screen is convenient at the same time.
Description
Technical field
The invention belongs to and force the intermittently vibratory sieve technical field of bituminous mixing plant, be specifically related to a kind of vibratory sieve that can be convenient for changing screen cloth.
Background technology
Force the intermittently vibratory sieve of asphalt mixing plant, in process of production, be constantly heated and be subject to the continuous impact of material, can cause sieve breakage, changing screen cloth is a day-to-day work that ensures the normal work of vibratory sieve.Vibrating screen mesh of the prior art is from sieve core both sides tensioning, and tensioning apparatus is the multiple-unit tensioning mode that adopts a screen cloth of polylith buckle tensioning; The stock guide being positioned at before discharging opening is fixed; Vibratory sieve top and both sides are provided with sealing plate, and the sealing plate of vibratory sieve both sides is monolithic constructions, leave manhole above sealing plate.While changing screen cloth, must be from manhole dismounting tensioning bolt; Need top seal plate all to open simultaneously.
, there is following outstanding problem in above-mentioned vibratory sieve: 1, tensioning apparatus is the multiple-unit tensioning mode that adopts a screen cloth of polylith buckle tensioning, makes screen cloth stress point too many, discontinuity, and sieve breakage is fast, replacing is frequent.2, vibratory sieve both sides sealing plate is overall structure, while changing screen cloth, must be from manhole dismounting tensioning bolt, and its narrow space, not quick detachable.3, because the stock guide before discharging opening is fixed, can not screen cloth be taken out or be put into from discharging opening, while changing screen cloth, top seal plate all need be opened, could take out old screen cloth and the new screen cloth of installation.Inconvenient operation, spended time is long, inefficiency.
Summary of the invention
Object of the present invention, is to overcome the deficiencies in the prior art, provides one to make that screen cloth is stressed to be tending towards evenly, and extend service life, is convenient for changing a kind of vibratory sieve of screen cloth simultaneously.
Technical scheme of the present invention is: a kind of vibratory sieve, comprise sealing plate, stock guide, screen cloth and screen cloth tensioning device, described screen cloth tensioning device is made up of two stretching units, described stretching unit is by screen cloth side plate, buckle, screw rod, nut, screen cloth, support angle steel and crossbeam composition, described buckle and screen cloth side plate have equal length, pass through screw rod, nut and screen cloth side plate are fastenedly connected, make buckle that screen cloth is strained tightly and supported on angle steel and crossbeam, described screen cloth side plate is provided with manhole, four angles of described manhole are fillet, its arranged outside has gland, described screen cloth side plate arranged outside has split type sealing plate, described split type sealing plate is longitudinally to arrange.
Described stock guide is convertible stock guide, and stock guide lower hinge is in vibratory sieve frame, and top is bolted on screen cloth side plate.
Beneficial effect of the present invention: 1, because the tensioning apparatus of screen cloth is made up of two overall stretching units, a screen cloth is one-sided by a buckle tensioning, it is stressed evenly, the stress of screen cloth while having improved vibratory sieve work, can effectively reduce the fault rate of vibratory sieve, improve the service life of screen cloth.2, while changing screen cloth, only need open changing the corresponding sealing plate of screen cloth with need, the screw rod of screen cloth side plate is unclamped, need not dismantle completely, can damaged screen cloth be laid down by manhole, new screen cloth is installed, greatly save the time of changing screen cloth.3, due to after stock guide overturns, can be from discharging opening by screen cloth pull-out or put into, change screen cloth and need not dismantle top seal plate, saved the time, improved efficiency.4, owing to having improved the service life of screen cloth, shorten the time of changing screen cloth, reduce production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is stock guide syndeton schematic diagram.
Fig. 3 is stretching unit schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of vibratory sieve, comprise sealing plate 3, stock guide 1, screen cloth 8 and screen cloth tensioning device, screen cloth tensioning device is made up of two stretching units, stretching unit is by screen cloth side plate 12, buckle 5, screw rod 6, nut 7, screen cloth 8, support angle steel 9, crossbeam 10 forms, buckle 5 and screen cloth side plate 12 have equal length, by screw rod 6, being fastenedly connected of nut 7 and screen cloth side plate 12, make buckle 5 that screen cloth 8 is strained tightly and supported on angle steel 9 and crossbeam 10, screen cloth side plate 12 is provided with manhole 2, four angles of manhole 2 are fillet, its arranged outside has gland, screen cloth side plate 12 arranged outside have split type sealing plate 3, split type sealing plate 3 is longitudinally to arrange, can all dismantle, stock guide 1 is convertible stock guide, stock guide 1 bottom is hinged in vibratory sieve frame by hinge 11, top is fixed on screen cloth side plate 12 by bolt and angle bar 4.
When changing screen cloth 8, which piece screen cloth observation need to change, and opens the split type sealing plate 3 of corresponding region, then unclamps the screw rod 6 of the corresponding screen cloth on sieve core side plate 12, need not dismantle completely, unclamps.Lay down the gland of corresponding region, arm is stretched into manhole 2, back down gap with handgrip buckle 5, unclamp the bolt on stock guide 1 top, stock guide 1 turn to level by hinge 11, the screen cloth that needs are changed pull-out slowly.
When new screen cloth is installed, equally arm is stretched in manhole 2, back down gap with handgrip buckle 5, new screen cloth is sent to, then fastening screw rod 6, screen cloth 8 is strained and supported on angle steel 9 and crossbeam 10, fastening good gland, then installs split type sealing plate 3.
