Description
Technical field
The utility model relates to a kind of mixing arrangement, particularly a kind of mixing hopper for slurry in petroleum solid control apparatus.
Background technology
The drilling fluid of the explorations such as petroleum gas and production drilling well is that a kind of band is corrosive and contains a lot of Bu Tong suspension of the solid particle of size, and the preparation of this suspension extensively adopts mixing hopper.In the solid controlling system of processing at drilling fluid, preparation or increase drilling fluid total amount, change drilling fluid density, viscosity, dehydration etc., all need drilling fluid materials (swell soil, blanc fixes etc.) drop in solid controlling system with mutually deserved chemical addition agent (polymer etc.), directly input can cause a large amount of precipitations or become block, can not get good dispersion, therefore, need mixing arrangement; In Process of Oil Well Drilling, may there is blowout in emergency circumstances, need evenly to mix at short notice a large amount of weighting materials, there is no a kind of well behaved drilling fluid materials mixing arrangement, may cause serious consequence.Mixing hopper is the main liquid dispensing device of solid controlling system, and its reliability is especially crucial under the situation of above-mentioned possible blowout, and therefore, user is when choosing mixing arrangement, and the performance of mixing hopper and reliability of structure are the contents that user's emphasis is concerned about.
Oil solid controlling system mixing hopper is Venturi tube injecting type operating principle, and which Main Function is to increase the shearing force of liquid in pipe, so that material disperses better and improves the pressure head that mixes rear liquid, to enter circulating tank; In fact mixing hopper has utilized that " flow soon, pressure is low; Flow slowly, pressure is high " uncle's slave profit effect.
The typical structure of mixing hopper comprises that nozzle, mixing chamber (threeway), Venturi tube (horn mouth), funnel and butterfly valve form.Foreign oil drilling well solid controlling mixing hopper is connected employing welding manner with the exterior line of pipeline at present, and nozzle is connected with Venturi tube (horn mouth) and adopts sealed tube to be threaded with mixing chamber (threeway), threeway.Domestic rig is digested and assimilated when introducing mixing hopper, and Main change is: mixing hopper adopts flange to connect with being connected of exterior line, and inner sealing gas thread connects constant.Due to the machining control difficulty of sealed tube screw thread, when screwing, the flange hole position skew on reducer union and horn mouth, cannot align with exterior line flange hole, for alignment connects, only unscrew reducer union and horn mouth, cause to connect and become flexible and leak, need to be coated with a large amount of fluid sealants, unreliable.For addressing this problem ，You producer, reducer union, horn mouth are connected all and are welded with the inside of threeway, the problem of having brought so again nozzle not change.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the mixing hopper for slurry in petroleum solid control apparatus that a kind of inner connecting structure is compact, sealing reliably and not affects the replacing after nozzle wear is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of mixing hopper for slurry in petroleum solid control apparatus, it comprises threeway, base, reducer union, funnel and horn mouth, on two ends, the left and right cylindrical of described threeway, be provided with annulus draw-in groove, the bottom of threeway is fixed on base, between the top of threeway and the bottom of funnel, be provided with valve, one end of threeway coordinates and is connected with reducer union, and reducer union and annulus draw-in groove are provided with thimble connector, on the inwall of reducer union, be provided with gas thread, reducer union is connected by threaded engagement with nozzle, the other end of threeway coordinates and is connected with horn mouth, and horn mouth and annulus draw-in groove are also provided with thimble connector.
Described valve is butterfly valve.
Described below, threeway side is provided with plug.
Advantage of the present utility model is: mixing hopper can be connected with exterior tubing flange very fast, and inner connecting structure is compact; Employing flange connects, and has guaranteed mixing hopper and the outside position being connected, and significantly improved the sealing performance of mixing hopper, and dismounting is also very convenient, quick, does not affect the replacing after nozzle wear.
