Abstract

The utility model provides a slurry mixing tank, and relates to a device used for well cementing slurry mixing and preparation. The device can correct the defects in the prior slurry mixing pot, such as the slurry has poor fluidity, is apt to deposit and causes inconvenience to washing, and therefore only a mammoth equipment provided with a slurry mixing system can solve the problem. The device comprises a tank bottom, tank walls, a discharge outlet, a sewage pipe, a gas diffusion chamber flange and two agitators; as for the structure of the tank bottom, inclined steps are formed on the tank bottom and arranged in a smooth transition from one to another, and the bottommost part of the tank bottom adopts an arc structure; the bottom halves of tank walls on two sides incline inwards; at least one discharge outlet is mounted at the bottommost part on two side surfaces of the tank walls which is tangential to the arc structure or the bottommost part below the tank body, which is vertical to the middle-and-rear part of the arc structure; the sewage pipe is arranged in the central position of the arc structure, and can also be arranged in any position rotating forwards and backwards along the arc structure from the central position; and two washing openings are formed on the top surface of the tank body and between the gas diffusion chamber flange and the tank walls. The device can be widely mounted on equipment with a slurry mixing system for well cementing slurry mixing and preparation.

Description

Slurry mixing tank

Technical field

The utility model relates to a kind of well cementation mud equipment therefor that is mixed.

Background technology

At present land and the offshore oilfield employed slurry mixing tank of mud that is mixed all is straight tank skin, and at the bottom of the horizontal retort, and the tank deck face almost completely seals.Such shortcoming is to be unfavorable for flowing of mud, causes the mud deposition, and the water wasting of cleaning slurry mixing tank was time-consuming again after operation was finished.Simultaneously, existing slurry mixing tank is unfavorable for causing equipment volume huge with the integral layout of the equipment that mixes the slurry system.

The utility model content

The purpose of this utility model is, a kind of slurry mixing tank is provided, and overcomes that existing slurry mixing tank slip fluidity difference easily deposits, inconvenience is cleaned and cause band to mix the huge defective of equipment volume of slurry system.

The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of slurry mixing tank, at the bottom of comprising jar, tank skin, outlet opening, blow-off pipe, gas diffusion chamber flange and be installed in two agitators on the tank body; The oblique structure down of ladder is adopted at the jar end, adopts rounding off, and jar end lowest part employing arc structure, and both sides tank skin the latter half slopes inwardly; In the two sides of tank skin and with the lowest part of arc structure direction tangential or below tank body and with the lowest part of arc structure postmedian vertical direction, an outlet opening is installed at least.Blow-off pipe is arranged at the center of arc structure, also can be arranged on from the center on the optional position along the rotation of arc structure front and back.At the tank body end face, be provided with two Butterworth Hatchs between gas diffusion chamber flange and the tank skin.

The beneficial effect that the utility model is had compared with the prior art is: the unique design of (1) jar end and tank skin, can effectively reduce mud attached to jar at the bottom of and the probability of tank skin, strengthen and mix the slurry effect.(2) can outlet opening be set in three orientation, help reducing the volume that band mixes the equipment of slurry system, make device miniaturization.(3) blow-off pipe is arranged at the arc structure center, can be farthest mud and dirt be got rid of, and solidifies at the bottom of avoiding mud emission totally not cause jar.(4) be provided with two Butterworth Hatchs, be convenient to clean.

The specific embodiment

The utility model will be further described by embodiment below in conjunction with Figure of description:

Connect the otic placode 6 of slurry mixing tank and the otic placode on the end sledge by bearing pin 4, thereby slurry mixing tank is fixed on the end sledge of being with the equipment that mixes the slurry system, outside dirt-discherging pipe manifold can be directly connected on the blow-off pipe 5 by butterfly valve.As shown in Figure 1, be provided with two outlet openings 3 in the two sides of tank skin 2 and with the lowest part of arc structure direction tangential, connect circular centrifugal pump and the centrifugal pump intake of perfusion respectively, suction capacity by two centrifugal pumps, can increase the flowability that pot bottom divides mud better, make mud be in flow regime always, prevent to produce slurry curing because of long-time well cementing operation.As shown in Figure 3, the oblique structure down of ladder is adopted at jar end 9, so side space is broad under the tank body, one of them centrifugal pump can be installed in the tank body below, with better saving space, increase the integral layout ability of equipment, this centrifugal pump that is installed in the tank body below is easier to repairing and keeping simultaneously.Centrifugal pump promptly can be injected in the three-cylinder plunger pump after drawing mud, in the slurry mixing tank that also mud can be reinjected.Be installed in two agitators 1 on the tank body, the mud in the slurry mixing tank is stirred.After operation finishes, by being arranged at two Butterworth Hatchs 7 between gas diffusion chamber flange 8 and the tank skin 2, the flushing manifold that carries with the equipment of being with mixed slurry system washes tank interior, prevents residual mud at the tank interior surface cure, and is easy to operate, reliable.

Claims

[claim 1] a kind of slurry mixing tank, (9), tank skin (2), outlet opening (3), blow-off pipe (5), gas diffusion chamber flange (8) and be installed in two agitators (1) on the tank body at the bottom of comprising jar, it is characterized in that: the oblique structure down of ladder is adopted at a jar end (9), adopt rounding off, and jar end (a 9) lowest part adopts arc structure, and both sides tank skin (2) the latter half slopes inwardly; In the two sides of tank skin (2) and with the lowest part of arc structure direction tangential or below tank body and with the lowest part of arc structure postmedian vertical direction, an outlet opening (3) is installed at least.
[claim 2] slurry mixing tank according to claim 1 is characterized in that: blow-off pipe (5) is arranged at the center of arc structure, also can be arranged on from the center on the optional position along the rotation of arc structure front and back.
