A disc spring and a piston are arranged in a cylinder body of the compaction mechanism, and a piston rod is connected with the piston, and is arranged in a rod cavity. A screw rod is connected with the piston, and one end of the screw rod is provided with a nut for positioning. A double liquid pool large handling capacity vibrating screen increases the handling capacity, also guarantees the treatment strength, can achieve the balanced elliptical movement track of the screen box, can achieve the soft starting of an exciting motor and the change of the amplitude and frequency of the screen box through an inverter, and is a more ideal screen box structure for treating drilling fluid.
Description
One, technical field:
The utility model relates to a kind of oil field first order equipment that drilling fluid is carried out solid phase control, especially a kind of biliquid pond balanced elliptic drilling fluid vibrating sieve.
Two, background technology:
Various types of vibrosieve has been equipped with and has been used in effective separation process of oil well drilling process and drilling fluid and harmful solid phase, but common shortcoming is: vibrosieve screen box structure utilization rate is low, the liquid pool area that forms is little, treating capacity is few, the loaded down with trivial details inconvenience of mounting means changes especially that sieve speed is lost time slowly, manpower.
Three, summary of the invention:
The purpose of this utility model provides a kind of biliquid pond balanced elliptic drilling fluid vibrating sieve that can improve treating capacity and change sieve speed, and it has overcome the shortcoming that other technologies exist.The purpose of this utility model is to realize like this, it is to be formed by connecting by screen cloth layout structure and quick compressing structure two parts, the screen cloth layout structure is to be formed by connecting by two concave meniscus liquid pools, the screen cloth layout structure is to be formed by connecting by super rigidity screen cloth, concave arc screen box, liquid pool locating piece, quick hold-down mechanism, screen cloth handle, and the screen cloth handle is positioned at a side of super rigidity screen cloth; Super rigidity screen cloth places the liquid pool locating piece and fast between the hold-down mechanism, is positioned at the concave arc screen box, and is connected with the screen cloth holddown groove of the negative incidence structure of liquid pool locating piece, and the dish spring is connected with the concave arc screen box by support bar.
Hold-down mechanism is to be formed by connecting by screen cloth holddown groove, dish spring, support bar, cylinder body, piston fast, and dish spring, piston are arranged in the hold-down mechanism cylinder body; Support bar is connected with piston, and is positioned at rod chamber.
Screw rod is connected with piston, at an end of screw rod the nut location is arranged.
After installing by the unequal shock electric machine of plural exciting force, " centre of force " that the installation site of shock electric machine should be able to make exciting force make a concerted effort overlaps with the barycenter of screen box integral body, realize the balanced elliptic movement locus of screen box, and can realize the soft start of shock electric machine and the variation of screen box amplitude and frequency by frequency converter.
It is to be formed by connecting by screen cloth layout structure and quick compressing structure two parts, the screen cloth layout structure is to be made of two concave meniscus liquid pools, screen cloth adopts super rigidity material, concave arc liquid pool structure ratio screen box both sides liquid pool structure has in the past increased the contact area with drilling fluid, helps increasing treating capacity; Hold-down mechanism is to provide certain pressure to make compressing structure be in contraction state by power source system to be convenient to take out screen cloth fast, remove behind the power source elastic force that the dish spring by compressing structure inside produces and fast screen cloth is pressed in the screen cloth holddown groove of liquid pool locating piece, reach the purpose that compresses fast; When providing certain pressure to make quick hold-down mechanism be in contraction state, the power source of quick hold-down mechanism is convenient to take out screen cloth, removing behind the power source elastic force that the dish spring by quick hold-down mechanism inside produces is pressed into screen cloth fast by support bar in the negative incidence groove of screen cloth holddown groove of liquid pool locating piece, reach the purpose that compresses fast, and fit tightly with concave arc screen box structure and to form the structure strong liquid pool that compacts and not only increased treating capacity but also guaranteed processing intensity.
Power source is pressed into medium in the rod chamber of cylinder body, and medium can be divided into gas and liquid, and the pressure increase produces powerful thrust and makes the compression of dish spring in the rod chamber on piston, and piston drives support bar and moves in cylinder body, thereby unclamps screen cloth; Power source stops medium being sent in the rod chamber of cylinder body, and the medium in the rod chamber overflows simultaneously, and pressure recovers atmospheric pressure in the rod chamber, the dish spring does not stress, and recovers deformation, promotes piston reset, piston drives support bar and moves outside cylinder body, thereby screen cloth is pressed on the concave arc screen box structure.
Power source can be divided into hydraulic pressure, pneumatic, manual three kinds of modes.Wherein hydraulic pressure and pneumatic mode adopt fluid cylinder or cylinder to compress, and its principle is identical, and as above hold-down mechanism is described fast for concrete connected mode.Manual mode is utilized nut to screw on screw rod or is unloaded pine and screw rod advanced or retreat and reach the purpose that compresses or unload loose screen cloth.
The beneficial effects of the utility model are that concave arc liquid pool structure ratio screen box both sides liquid pool structure has in the past effectively increased the contact area with drilling fluid, helps increasing treating capacity; Compressing structure has made full use of hydraulic pressure fast, pneumatic or manual advantage reaches the purpose of unloading pine fast and compressing screen cloth, effectively improves treating capacity and screen cloth installation rate, saves manpower, cost.
