Abstract
A device capable of quickly replacing a sieve of a vibration screen comprises a screen body 1, the sieve 2, a T-type bolt 3, a hook plate 4, a fixing base 5, an adjusting nut 6, a spring washer 7 and a locking nut 8. The hollow fixing base 5 is welded to the outer side of the screen body 1 and is in connection with the hollow adjusting nut 6 through external threads. A bolt hole is formed in the screen body 1. A long-strip-shaped hole in the hook plate 4, the bolt hole in the screen body 1, a center hole in the fixing base 5 and a center hole in the adjusting nut 6 share the same axis. The long-strip-shaped hole in the hook plate 4 allows the head of the T-type bolt 3 to penetrate through. The fixing base 5 is connected with the adjusting nut 6 through a double-end trapezoid thread, wherein the screw lead of the double-end trapezoid thread is 5-10 times that of the T-type bolt 3 and that of the locking nut 8, and namely when the adjusting nut 6 rotates by one circle, the locking nut 3 rotates by 5-10 circles. Therefore, compared with the time used for rotating the locking nut 8 in the prior art, the time used for rotating the adjusting nut 6 is saved by 90% when the sieve needs to be detached, and accordingly labor intensity of workers is reduced greatly.
Description
Technical field
The utility model relates to the vibratory sieve technical field, particularly a kind of device of quick-replaceable vibrating screen mesh.
Background technology
The at present solid phase one-level of drilling fluid separation is all finished by vibratory sieve, and the installation of conventional vibration sieve screen cloth and replacing operation all rely on the adjusting lock nut to finish, but because locking nut pitch is shorter, in the process of dismounting screen cloth, usually need rotation lock nut 10-15 circle, its complicated operation, time-consuming, effort have affected the efficient of drilling operation to a certain extent.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of device of quick-replaceable vibrating screen mesh is provided, and it is reasonable in design, and is simple in structure, easy to operate, can realize quick installation and the replacing of screen cloth, and production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of device of quick-replaceable vibrating screen mesh is by sieve nest 1, screen cloth 2, T-shaped bolt 3, colludes plate 4, holder 5, adjusting nut 6, spring shim 7 and locking nut 8 and consist of.Sieve nest 1 is provided with bolt hole, the bolt hole place is welded with hollow holder 5 in sieve nest 1 outside, and its external screw thread is connected with hollow adjusting nut 6 internal threads, and colluding has strip hole, T-shaped bolt 3 therefrom to penetrate on the plate 4, through bolt hole, holder 5, the adjusting nut 6 on the sieve nest 1, tighten with locking nut 8; Holder 5 and adjusting nut 6 relies on the two-wire trapezoidal threads to be connected, the helical pitch of two-wire trapezoidal thread be T-shaped bolt 3 and locking nut 8 screw thread that adopts helical pitch 5-10 doubly, namely adjusting nut 6 every rotations one circles are equivalent to locking nut 8 rotation 5-10 and enclose.Therefore when the dismounting screen cloth, can save for 90% time by rotation adjusting nut 6 than rotation lock jack panel 8, realize quick installation and the replacing of screen cloth.
The described strip hole that colludes on the plate 4 can make the head of T-shaped bolt 3 pass.
When needs tensioning screen cloth 2, at first rotate T-shaped bolt 3, the long limit that makes T-shaped bolt 3 heads is vertical with the long limit of strip hole on colluding plate 4, then in the situation of not rotation lock nut 8, only need be rotated counterclockwise adjusting nut 6, can drive locking nut 8 and move right, T-shaped bolt 3 be compressed collude plate 4, realize the quick tensioning of screen cloth 2; When needs were changed screen cloth 2, then the adjusting nut 6 that at first turns clockwise only needed 90 ° of the end rotations of T-shaped bolt 3, make the head of T-shaped bolt 3 pass the strip hole that colludes on the plate 4, can in the situation of T-shaped bolt 3 of not dismantling, will collude plate 4 and pull down, and make replacing screen cloth 2 convenient and swift.
The beneficial effects of the utility model are: in the prior art, the dismounting screen cloth needs rotation lock nut 10-15 circle, and in the utility model, what adjusting nut adopted is the two-wire trapezoidal thread, its helical pitch be the used screw thread of locking nut helical pitch 5-10 doubly, therefore only need to rotate the dismounting that adjusting nut 1-2 circle just can be realized screen cloth, compare, change a used time of screen cloth and saved 90% than prior art, reduced labour intensity, be convenient to promote the use of.
