Description
Technical field
The present invention relates to a kind of drilling well vibratory sieve, relate in particular to a kind of tensioning mechanism for screen mesh of vibratory screen, belong to the vibratory sieve technical field.
Background technology
At present, the scope of application of vibratory sieve is very extensive, all needs to use when processing, manufacturing, almost relates to the every aspect in the life.Vibratory sieve is mainly used in the industries such as oil, coal, smelting, building materials, refractory material, light industry, chemical industry, medicine, food, and that uses in the oil drilling industry especially is extremely frequent.In petroleum drilling operation, vibratory sieve is mainly used in removing landwaste and other the harmful solid phase particles in the drilling fluid, and it requires larger treating capacity on the one hand, solid phase particles in the energy removing drilling fluid as much as possible; Require on the other hand continuous renewal and the development of vibratory sieve.A large amount of facts have proved, vibrosieve decides from the ability of the drilling cuttings main working parts screen cloth by it, thus the performance of vibratory sieve quality major part determined by screen cloth, and determine a strainer that vitals is exactly screen cloth of screen cloth performance.
In the prior art, the drilling fluid vibrating sieve that in oil drilling, uses, its strainer that adopts is fixed, when large or screen cloth eye occurs by the clay coating phenomenon when flow, thereby the undesirable condition impact production of mud can occur to run, and landwaste overstand on screen cloth can accelerate the wearing and tearing of screen cloth simultaneously.Therefore, relatively flexible in the urgent need to a kind of tensioning mechanism for screen mesh of vibratory screen is provided, can regulate according to actual needs strainer, and simple and easy to do, enhance productivity, can reduce again the wearing and tearing of screen cloth simultaneously, prolong the service life of screen cloth.
Summary of the invention
The objective of the invention is for above-mentioned the deficiencies in the prior art, thereby provide a kind of tensioning mechanism for screen mesh of vibratory screen, the present invention adopts the active card fingerboard to fix screen cloth, and by rational structural design so that agile and all-purposeization of screen cloth strainer, can prolong the service life of screen cloth.
The objective 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 place screen frame inboard, and active card refers to be embedded in active card and instructs on the plate; The cam shell places the screen frame outside, adjusting bolt is through in the adjustment hole that arranges on the cam shell, the one end connection of adjusting bolt places the active card of screen frame inboard to refer to, the other end is installed tensioning nut, adjusting nut successively, tensioning nut is screwed in the cam tracks that arranges on the cam shell, and adjusting nut is screwed on the adjusting bolt.
The contacted end of described tensioning nut and adjusting nut is provided with installing hole, and adjusting nut is located in the installing hole.
Described active card instructs between plate and the screen frame and is provided with spring, and spring, active card instruct plate to pass through bolt, bullet pad, pad, nut to be connected with the cam shell.
Described spring is steel sheet spring.
Described cam shell and screen frame outer wall fit, and are provided with the O RunddichtringO between cam shell and the screen frame outer wall.
Be provided with the O RunddichtringO between described tensioning nut and the adjusting bolt.
An end of tensioning nut withstands on the guide rail of cam among the present invention, and then the coarse adjustment by the tensioning of rotation tensioning nut realization screen cloth realizes the accurate adjustment of screen cloth tensioning by the rotation adjusting nut.Steel sheet spring is contained in the screen frame inwall and active card instructs between the plate, prevents from making when instructing plate and cam with the fastening active card of bolt and nut deformation.The realization of vibrating screen mesh tensioning is divided into coarse adjustment and two steps of accurate adjustment, 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 so that the adjusting bolt bar is outwards mobile, the moving active card of the outer shipper pole of adjusting bolt bar refers to instruct outwards motion on the plate in active card, thereby realizes the coarse adjustment of screen cloth tensioning.The concrete grammar of accurate adjustment is as follows: turn adjusting nut, adjusting nut so that adjusting bolt move outward, thereby drive outer the moving that active card refers to, thereby finish the accurate adjustment of vibrating screen mesh tensioning.The present invention adopts the tensioning apparatus of similar cam, and structural design is ingenious, is combined with steel sheet spring, has reduced the distortion of mechanism.The present invention adopts the two governor motions of coarse adjustment and accurate adjustment, comes the tensioning situation of adjustable screen according to the real work needs, makes the tight tensioning of screen cloth, has prolonged the service life of screen cloth.
Description of drawings
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 among Fig. 1;
Among the 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.
