Description
Technical field
The present invention relates to a kind of drilling well vibratory sieve, particularly relate to a kind of tensioning mechanism for screen mesh of vibratory screen, belong to vibratory sieve technical field.
Background technology
At present, the scope of application of vibratory sieve is very extensive, all needs to use, almost relate to the every aspect in life when processing, manufacture.Vibratory sieve is mainly used in the industries such as oil, coal, smelting, building materials, refractory material, light industry, chemical industry, medicine, food, extremely frequent especially in oil drilling industry.In petroleum drilling operation, vibratory sieve is mainly used in removing the landwaste in drilling fluid and other harmful solid phase particles, and it requires larger treating capacity on the one hand, solid phase particles in energy removing drilling fluid as much as possible; Require continuous renewal and the development of vibratory sieve on the other hand.A large amount of facts have proved, vibrosieve is decided from the ability of drilling cuttings by its main working parts screen cloth, so the performance quality major part of vibratory sieve is determined by screen cloth, and determines that a vitals of screen cloth performance is exactly the strainer of screen cloth.
In prior art, the drilling fluid vibrating sieve used in oil drilling, its strainer adopted is fixing, when flow is comparatively large or screen cloth eye occurs by clay coating phenomenon, the undesirable condition of race mud can occur thus affect production, landwaste overstand on screen cloth can accelerate the wearing and tearing of screen cloth simultaneously.Therefore, in the urgent need to providing a kind of tensioning mechanism for screen mesh of vibratory screen relatively flexible, strainer can be regulated according to actual needs, and simple and easy to do, enhance productivity, the wearing and tearing of screen cloth can be reduced again simultaneously, extend the service life of screen cloth.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, thus a kind of tensioning mechanism for screen mesh of vibratory screen is provided, the present invention adopts active card fingerboard to fix screen cloth, and makes screen cloth strainer agile and all-purposeization by rational structural design, can extend the service life of screen cloth.
The object of the invention is to be achieved through the following technical solutions: tensioning mechanism for screen mesh of vibratory screen, it is characterized in that, be provided with that active card refers to, cam shell, tensioning nut, adjusting nut, adjusting bolt, active card instruct plate, active card refers to, active card instructs plate to be placed in inside screen frame, and active card refers to that being embedded in active card instructs on plate; Cam shell is placed in outside screen frame, adjusting bolt is through in the adjustment hole that cam shell is arranged, one end of adjusting bolt connects the active card be placed in inside screen frame and refers to, the other end installs tensioning nut, adjusting nut successively, tensioning nut is screwed in cam tracks that cam shell is arranged, and adjusting nut is screwed in adjusting bolt.
One end that described tensioning nut contacts with adjusting nut is provided with installing hole, and adjusting nut is located in installing hole.
Described active card instructs between plate and screen frame and is provided with spring, and spring, active card instruct plate to be connected with cam shell by bolt, bullet pad, pad, nut.
Described spring is steel sheet spring.
Described cam shell and screen frame outer wall fit, and are provided with O RunddichtringO between cam shell and screen frame outer wall.
O RunddichtringO is provided with between described tensioning nut and adjusting bolt.
In the present invention, one end of tensioning nut withstands on the guide rail of cam, realizing the coarse adjustment of screen cloth tensioning, then being realized the accurate adjustment of screen cloth tensioning by rotating adjusting nut by rotating tensioning nut.Steel sheet spring is contained in screen frame inwall and active card instructs between plate, prevents from making deformation instructing when plate and cam by the fastening active card of bolt and nut.The realization of vibrating screen mesh tensioning is divided into coarse adjustment and accurate adjustment two steps, the concrete grammar of coarse adjustment is as follows: turn tensioning nut, tensioning nut moves along cam tracks, move in the rotation of tensioning nut and make the outwards movement of adjusting bolt bar, the outer shipper pole of adjusting bolt bar moves active card and refers to instruct on plate in active card outwards move, thus realizes the coarse adjustment of screen cloth tensioning.The concrete grammar of accurate adjustment is as follows: turn adjusting nut, and adjusting nut makes to move outside adjusting bolt, thus moving outward of driving active card to refer to, thus complete the accurate adjustment of vibrating screen mesh tensioning.The present invention adopts the tensioning apparatus of similar cam, and smart structural design is combined steel sheet spring, decreases the distortion of mechanism.The present invention adopts coarse adjustment and the two governor motion of accurate adjustment, needs to come the tensioning situation of adjustable screen, make the tight tensioning of screen cloth, extend the service life of screen cloth according to real work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 left view;
Fig. 3 is A-A sectional structure schematic diagram in Fig. 1;
In figure: 1 spring, 2 active card refer to, 3 cam shells, 4 O RunddichtringOs, 5 O RunddichtringOs, 6 tensioning nuts, 7 adjusting nuts, 8 adjusting bolts, 9 bolts, 10 bullet pads, 11 pads, 12 nuts, 13 active card instruct plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Tensioning mechanism for screen mesh of vibratory screen, comprises screen frame, and steel sheet spring 1, active card refer to 2, cam shell 3, tensioning nut 6, adjusting bolt 8, active card instruct plate 13, and active card refers to that being embedded in active card instructs on plate.
Steel sheet spring 1, active card refer to 2, active card instructs plate 13 to be placed in inside screen frame.The active card that is arranged on steel sheet spring instructs between plate and screen frame, and active card instructs plate, steel sheet spring to be connected by bolt 9, bullet pad 10, pad 11, nut 12 and the cam shell be placed in outside screen frame.Cam shell and screen frame outer wall fit, and are provided with O RunddichtringO 4 between cam shell and screen frame outer wall.Adjusting bolt is through in the adjustment hole that cam shell 3 is arranged, one end of adjusting bolt 8 connects the active card be placed in inside screen frame and refers to, the other end installs tensioning nut 6, adjusting nut 7 successively, tensioning nut is screwed in the cam tracks of setting on cam shell 3, adjusting nut is screwed in adjusting bolt, one end that tensioning nut contacts with adjusting nut is provided with installing hole, and adjusting nut is located in installing hole.O RunddichtringO 5 is provided with between tensioning nut and adjusting bolt.
Realizing the coarse adjustment of screen cloth tensioning by rotating tensioning nut, then being realized the accurate adjustment of screen cloth tensioning by rotating adjusting nut.The coarse adjustment carried out respectively by the present invention and accurate adjustment, make the tight tensioning of vibrating screen mesh.Novelty of the present invention is ingenious, simple and easy to do, enhance productivity, the tight tensioning of screen cloth can be made and cause screen cloth be subject to the factors such as excessive extrusion stress and produce larger wearing and tearing simultaneously, effectively can extend the service life of screen cloth, and make screen cloth all the time in the duty of the best.
