Description
Technical field
The utility model belongs to oil and gas exploration equipment technical field, relates to a kind of drilling pump low pressure slurry filter.
Background technology
The pipeline that connects drilling pump and slurry tank or mud pit is called suction manifold; because slurry tank or mud pit are outdoor; in tank or pond, often have some bulky grain foreign material; and these foreign material can affect the service life of drilling pump parts; outside must being blocked in; therefore on suction manifold, conventionally must be equipped with low pressure slurry filter, for filtering drilling fluid, in case large granular impurity enters drilling pump and damage equipment. After stopping up, slurry filter can affect the upper water-based energy of drilling pump, even cause drilling pump cisco unity malfunction, in order not affect drilling pump work, must clear up rapidly low pressure slurry filter, this just requires low pressure slurry filter to have the feature of quick easy to clean.
At present, what field operations scene was used is board-like low pressure slurry filter, and its filter core is netted plank frame, according to the direction of liquid stream direction board, low pressure slurry filter is arranged on drilling pump suction line. When work, drilling fluid flows into filtration barrel body, and the drilling fluid being filtered enters drilling pump, is greater than in the large cylinder that the particle of mesh and foreign material are blocked in low pressure slurry filter and can not enters drilling pump. Large particle and foreign material have been stayed in filtration barrel body, when large particle and foreign material run up to the intake performance that can affect drilling pump after a certain amount of, now just must clear up slurry filter.
Existing method for cleaning is, first unscrew the clamp nut on screen pack gland, then filter core entirety is brought out, but after mentioning filter core, those foreign material have been stayed in large cylinder, need to re-start cleaning to those large particles and foreign material in large cylinder again salvages, liquid stream inconvenience cleaning while simultaneously rinsing the mud of cylinder body bottom, time-consuming effort again, operation is inconvenience very. Owing to being manual salvaging, foreign material and drilling fluid mix, and are difficult to clean out. Due to structural limitations, between filter core and filtration barrel body, have gap in addition, while causing filtering slurry, sealing effectiveness is poor, affects drilling pump work.
Utility model content
The purpose of this utility model is to provide a kind of drilling pump low pressure slurry filter, has solved in prior art and has had filter dismounting complexity, and filter effect is undesirable, clears up not thoroughly, easily affects the problem of drilling pump work.
The technical scheme that the utility model adopts is, a kind of drilling pump low pressure slurry filter, comprise filtration barrel body, in filtration barrel body, be disposed radially a cavity, in this cavity, be provided with a cylindrical filter cartridge, this cavity one end is the fixing bottom of sealing, and this cavity other end is provided with screen pack gland; In the blind hole of bottom inner side, be installed with a positioning stud, the positioning stud other end stretches out screen pack gland through after cylindrical filter cartridge successively; In positioning stud outer end, thread bush is equipped with clamp nut, and rotating handles is installed on clamp nut; Radially have a through hole at this cavity near the wall of bottom, through hole is provided with a blowoff gate valve outward.
Drilling pump of the present utility model low pressure slurry filter, is further characterized in that:
Cylindrical filter cartridge and screen pack gland axle center hole contact position are provided with O RunddichtringO.
The structure of cylindrical filter cartridge is, comprise the filter cylinder of outer ring and inner screen pack, have centre bore in screen pack axle center for passing positioning stud, in cartridge wall, be drilled with uniform pore, filter cylinder outer surface is provided with two positioning strips along diameter symmetry, positioning strip is fixed on filter cylinder outer surface vertically, two positioning strips and two corresponding being slidably socketed of guide groove that are arranged on cavity inner surface.
The operating side of filter cylinder is installed with handle, has introducing port at filter cylinder towards the direction of mud entrance, is provided with back-up block in filter cylinder bottom.
The beneficial effects of the utility model are, this cartridge type low pressure slurry filter, and at drilling fluid, during by filter core, the particle and the foreign material that are greater than mesh are blocked in filter core completely, good filtration effect. After filter core is blocked need to clear up time, mentions filter core, those foreign material have been carried out simultaneously, are easy to cleaning. To being deposited on mud and the impurity of cylinder body bottom, can rinse and drain by gate valve simultaneously, solved the problem that has poor filtration effect and on-the-spot difficult operation in prior art.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present utility model is, comprise the filtration barrel body 1 with drilling pump suction line tandem docking, in filtration barrel body 1, be disposed radially a cavity, in this cavity, be provided with a cylindrical filter cartridge 2, this cavity one end is the fixing bottom of sealing, this cavity other end is provided with screen pack gland 8, in the blind hole of bottom inner side, be installed with a positioning stud 5, positioning stud 5 other ends stretch out screen pack gland 8 (positioning stud 5 is smooth contacts with screen pack gland 8) through after cylindrical filter cartridge 2 successively, be provided with O RunddichtringO 4 at cylindrical filter cartridge 2 and screen pack gland 8 axle center hole contact positions, at positioning stud 5 outer end thread bush, clamp nut 3 is housed, on clamp nut 3, rotating handles is installed, can cover tightly screen pack gland 8 and compress cylindrical filter cartridge 2 by rotatably compressing nut 3, radially have a through hole at this cavity near the wall of bottom, through hole is provided with a blowoff gate valve 11 outward.
With reference to Fig. 4, Fig. 5, the structure of cylindrical filter cartridge 2 is, comprise the filter cylinder 10 of outer ring and inner screen pack, have centre bore in screen pack axle center for passing positioning stud 5, on filter cylinder 10 walls, be drilled with uniform pore, filter cylinder 10 outer surfaces are provided with two positioning strips 12 along diameter symmetry, and positioning strip 12 is fixed on filter cylinder 10 outer surfaces vertically, two positioning strips 12 and two corresponding being slidably socketed of guide groove that are arranged on cavity inner surface; Be installed with handle 13 (Fig. 5 embodiment is two handles 13) in the operating side of filter cylinder 10, have introducing port 14 at filter cylinder 10 towards the direction (carrying out liquid direction) of mud entrance, be provided with back-up block 15 in filter cylinder 10 bottoms.
