Description
Technical field
The utility model relates to the oil field and uses the silt particle cleaning device, is specifically related to a kind of drilling fluid vibrating sieve.
Background technology
Drilling fluid vibrating sieve is to be used for drilling mud cleaning system one-level solid control equipment, is used for handle separating by mud institute when the well letter is returned out being with a large amount of drilling cuttings so that mud gets into the secondary separation equipment, at present; Drilling fluid vibrating sieve is directly fixed vibrating screen mesh and screen box through the fastening bolt of dense arrangement; In the maintenance of screen cloth with when changing, screen cloth is difficult to dismounting, and required time is long; Cost is high, is unfavorable for continuous production.
Summary of the invention
The purpose of the utility model is to solve the problems of the technologies described above, and provides a kind of screen cloth to change drilling fluid vibrating sieve easily and fast.
The technical scheme of the utility model is:
Drilling fluid vibrating sieve comprises screen box and screen cloth, and sieve box side plate is provided with screen cloth pad and fixed head, and screen cloth is positioned on the screen cloth pad, and the screen cloth hold down gag is between screen cloth and fixed head.
Concrete, the screen cloth hold down gag comprises that screen cloth clamps voussoir, voussoir alignment pin and telescopic cylinder, screen cloth clamps voussoir and is positioned at above the screen cloth; The end that screen cloth clamps voussoir is connected with telescopic cylinder; The voussoir alignment pin is fixed on the sieve box side plate, and screen cloth clamps on the voussoir bar hole is set, and one one of the voussoir alignment pin is positioned at bar hole; The end that bar hole is positioned at telescopic cylinder is higher than the other end; When the piston rod movement of telescopic cylinder, screen cloth clamps voussoir because the restriction of voussoir alignment pin and moving along bar hole, thereby compresses or unclamp screen cloth.
Concrete, the screen cloth hold down gag comprises that screen cloth clamps voussoir, voussoir alignment pin and telescopic cylinder, screen cloth clamps voussoir and is positioned at above the screen cloth; The end that screen cloth clamps voussoir is connected with telescopic cylinder; The voussoir alignment pin is fixed on screen cloth and clamps on the voussoir, and bar hole is set on the sieve box side plate, and one one of the voussoir alignment pin is positioned at bar hole; The end that bar hole is positioned at telescopic cylinder is higher than the other end; When the piston rod movement of telescopic cylinder, screen cloth clamps voussoir because the restriction of bar hole and moving along bar hole, thereby compresses or unclamp screen cloth.
Preferably, the soffit of said fixed block is parallel with bar hole.
Concrete, the screen cloth hold down gag is an air bag, through the inflation or the venting of air bag, thereby compresses or unclamps screen cloth.
Preferably, air bag is a strip shaped air sac
The beneficial effect of the utility model is: the utility model adopts screen cloth to clamp voussoir or air bag, can fix fast or dismantles screen cloth, and is simple in structure; Easy to operate; Shorten replacing screen cloth required time greatly, ensured the production continuity, had good popularization or using value.
