In the drilling process that oil well or gas well are built, drill bit is disposed in the end of drill string and is rotated to drilling well.
Know that the drilling fluid for " drilling mud " is pumped into drill bit to lubricate drill bit via drill string.Drilling mud is additionally operable to via formation
Annulus between drill string and drilling well is by the drilling cuttings produced by drill bit and other Solid Conveying and Meltings to ground.Wrapped in drilling mud
Containing expensive synthetic oil-base lubricating oil, first have to filter mud when using, remove the solid particle being relatively large in diameter, ability
Into desander or desilter, further to reduce the solid concentration in mud, mud purification effect is played.At present, generally make
Screened out with mud vibrating screen, but traditional shaker sieve nest is big, and screening efficiency is poor.
The content of the invention
There is provided a kind of petroleum drilling fluid solid aiming at the drawbacks described above that prior art is present for the purpose of this utility model
Particulate filter arrangement.
Its technical scheme is：Including device body, inlet, hydraulic cylinder, trace, liquid barrier, upper screen cloth, lower screen cloth,
Liquid outlet, is provided with inlet on the upper surface of device body, liquid outlet is provided with the right side lower end of device body, in device sheet
The internal side wall of body is connected with liquid barrier, every two in the end of each hydraulic cylinder provided with four hydraulic cylinders by trace
Be welded with screen cloth between group liquid barrier, screen cloth is divided into two kinds of upper screen cloth and lower screen cloth, described lower screen cloth include filter plate, groove,
Raised line, filter opening, are longitudinally provided with a plurality of groove on filter plate, and a plurality of raised line and groove vertical are transversely provided with filter plate and is intersected point
Cloth, filter opening is offered in the space that raised line and groove are intersected to form；Above-mentioned upper screen cloth is made up of sieve plate, groove and web plate,
It is provided with the middle part of sieve plate between polylith web plate, every block of web plate and passes through recess divides；Above-mentioned inlet is horn shape,
The lower end of inlet is provided with filter pocket, and filter pocket is arranged on the inner side of device body.
The beneficial effects of the utility model are：By inlet be designed as it is horn-like can prevent the splashes of drilling fluid,
Larger impurity can be blocked provided with filter pocket in the lower section of inlet, reduce the burden of screen cloth；Pass through the left and right of upper screen cloth
Mobile that larger particle is stayed in drilling fluid uniform filtering on upper screen cloth to, liquid barrier can prevent drilling fluid from being flowed out from side,
Influence screens out effect；Drilling fluid with smaller particle is screened out by moving left and right for lower screen cloth again, so as to obtain more dry
Net drilling fluid.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the structural representation of upper screen cloth；
Accompanying drawing 3 is the structural representation of lower screen cloth；
