Technical field
The utility model relates to oil field welldrilling mud-processing equipment technical field, is a kind of mechanism for fast-holding screen of vibration screen for well drill liquid specifically.
Background technology
Drilling fluid vibrating sieve is the first order equipment in solid control equipment, and after the effect that vibratory sieve uses directly affects, the work efficiency of what solid control equipment, directly affects the operating mode of drilling engineering down-hole.What solid control equipment after comparing, it had crosses fluidity, high efficiency, energy saving, decisive to solid controlling system for handling entirely.And the firmness of the Quick universal of screen cloth and compression all can affect the work efficiency of vibratory sieve.The compression mode that the fast-assembling screen cloth (frame screen cloth) of present drilling fluid vibrating sieve adopts is that contract type block compresses, workman needs use hammer in screen box, knock contract type block thus compress or unclamp screen cloth, repeatedly need knock just can complete and compress or unclamp, the difficulty of such increase workman work, reduces operating efficiency.
Utility model content
The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, provides a kind of vibratory sieve quick screen tight compression mechanism, and this mechanism design is reasonable, simple to operate, compresses effective, improves efficiency, reduction work difficulty that workman changes vibrating screen mesh.
The technical scheme that the quick screen tight compression mechanism of the utility model vibratory sieve adopts is as follows:
The quick screen tight compression mechanism of the utility model vibratory sieve, comprise screen cloth briquetting and the adjustment for controlling briquetting holds down assembly, screen cloth briquetting is positioned at adjustment and holds down assembly front end, adjustment holds down assembly and is through on screen box boxboard, screen cloth briquetting lower end is pressed in and is positioned on the screen cloth of screen box, described adjustment holds down assembly and comprises eccentric shaft, cam, fixed cover and nut, described cam is fixedly installed on eccentric shaft front portion, fixed cover to be nested with on eccentric shaft and to be positioned at cam rear, nut to be nested with on eccentric shaft and to be positioned at fixed cover rear, fixed cover rear portion is provided with locating notch, eccentric shaft is provided with dog screw, described dog screw is positioned at locating notch.
As preferred version of the present utility model, described screen cloth briquetting comprises triangle briquetting main body, is provided with pressure hole in the middle part of triangle briquetting main body, and cam is placed in pressure hole.
As preferred version of the present utility model, eccentric wheel is provided with compression direction board, described compression direction board is between fixed cover and nut.
As preferred version of the present utility model, fixed cover is provided with two O RunddichtringO.
The advantage of the quick screen tight compression mechanism of the utility model vibratory sieve is, this mechanism design is reasonable, simple to operate, compresses effective, improves efficiency, reduction work difficulty that workman changes vibrating screen mesh.

Detailed description of the invention
As shown in drawings, the quick screen tight compression mechanism of the utility model vibratory sieve, comprises screen cloth briquetting and the adjustment for controlling briquetting holds down assembly, and screen cloth briquetting is positioned at adjustment and holds down assembly front end, adjustment holds down assembly and is through on screen box boxboard, and screen cloth briquetting lower end is pressed in and is positioned on the screen cloth of screen box.Only need adjust during adjustment to regulate and hold down assembly by regulating the drive screen cloth briquetting that holds down assembly to realize compressing the step of unclamping to the screen cloth being positioned at screen box.
Described adjustment holds down assembly and comprises eccentric shaft, cam, fixed cover and nut, described cam is fixedly installed on eccentric shaft front portion, fixed cover to be nested with on eccentric shaft and to be positioned at cam rear, nut to be nested with on eccentric shaft and to be positioned at fixed cover rear, fixed cover rear portion is provided with locating notch, eccentric shaft is provided with dog screw, and described dog screw is positioned at locating notch.
Fixed cover is fixed on the hole wall of screen box boxboard, eccentric shaft can rotate relative to fixed cover, when eccentric shaft turns, drive the cam and dog screw synchronous axial system that are positioned on eccentric shaft, utilize fixed cover 1 and dog screw 7(to be fixed on eccentric shaft 3 to rotate together with eccentric shaft 3, dog screw 7 can only rotate in the indentation, there of fixed cover 1) can the anglec of rotation of locking eccentric 3.
Eccentric wheel is provided with compression direction board, and described compression direction board is between fixed cover and nut.Compress direction board to mark direction that screen cloth B should rotate and unclamp the direction that screen cloth B should rotate, nut check compresses direction board and produces axial float to prevent eccentric shaft.Fixed cover is provided with two O RunddichtringO.Two O RunddichtringO flows out for preventing the liquid in screen box A.
Described screen cloth briquetting comprises triangle briquetting main body, is provided with pressure hole in the middle part of triangle briquetting main body, and cam is placed in pressure hole.
The using method of the quick screen tight compression mechanism of the utility model vibratory sieve is:
After screen cloth B to lay and puts in place by user, (axle two ends all have transmission side's tenon on eccentric rotation axis 3, user-friendly), cam on eccentric shaft 3 is when eccentric shaft 3 rotates to pressing down screen cloth briquetting 2, and screen cloth briquetting 2 presses to screen cloth B simultaneously, and screen cloth briquetting 2 produces elastic deformation in the process compressed, dog screw 7 after cam crosses peak on eccentric shaft 3 contacts with the limiting stand 8 in fixed cover 1, screen cloth B is compacted, and cam is locked, avoids loosening because of vibration.
In like manner, then screen cloth B can be unclamped when reversely rotating eccentric shaft 3.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
