Description

Double-deck mixing sand tank

Technical field

The utility model relates to a kind of double-deck mixing sand tank, and it belongs to corollary equipment field, oil field.

Background technology

In corollary equipment field, oil field, increasingly high for the effect requirements that is mixed of sand blender.At present, it all is the individual layer mixing sand tank that mixing sand tank is equipped with in vehicle-mounted and sledge installing, and its structure is that top is cylindric, and the bottom is a frustum, and it is employed in jar mode of the middle feed liquor in top.This mode feed liquor is inhomogeneous, makes that the sand glue effect that is mixed is irregular, thereby influences operation quality.

The utility model content

The utility model provides a kind of double-deck mixing sand tank to the individual layer mixing sand tank feed liquor uniformity in the prior art and all relatively poor deficiency of sand glue effect that is mixed.

The technical scheme that the utility model solves the problems of the technologies described above is following:

A kind of double-deck mixing sand tank comprises outer jar, internal layer jar and blowdown apparatus, and said internal layer jar is located at outer jar inside, and said blowdown apparatus is located at outer jar bottom; Said outer jar is to be formed by fixedly connecting tank body closure plate, outer cylinder, peripheral board and base plate first, and said outer cylinder top is provided with gripper shoe and the water inlet pipe that has butterfly valve flange second, and said base plate first is provided with the water conservancy diversion baffle ring; Said internal layer jar comprises overflow coaming plate and the inner cylinder that is mutually permanently connected; Said overflow coaming plate top is provided with steel plate ring and is fixed on its peripheral water fender; Be provided with several gusset first between said water fender and the overflow coaming plate, said overflow coaming plate is provided with several gusset second; Said blowdown apparatus comprises rear blocking plate, end closure plate, side stopboard, upper plugging plate and the preceding closure plate that is mutually permanently connected, and is provided with butterfly valve flange first through iso-diameter elbow on the said rear blocking plate, and said preceding closure plate is provided with pipe joint.

Compared with prior art, the beneficial effect of the utility model is: dischargeable capacity increases, and makes feed liquor even, thereby guarantees under the situation of high sand ratio mortar, can mix fully with continuously.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, also comprise bracing or strutting arrangement, said bracing or strutting arrangement comprises supporting leg, and said supporting leg is installed on the peripheral board through gusset third, and the below of said supporting leg is provided with the base plate second that has otic placode.

Further, be provided with inner shield ring between said outer cylinder and the inner cylinder, said inner shield ring is fixed on the outer cylinder.

Further, be evenly equipped with six intercommunicating pores between said outer jar and the internal layer jar.

Adopt the beneficial effect of above-mentioned further scheme to be: the setting of bracing or strutting arrangement can make mixing sand tank be installed in vehicle-mounted very easily or sledge installing is equipped with; Inner shield ring has reduced the kinetic energy of outer feed flow; Make it in outer jar, after the circulation, get into the internal layer jar through the radial hole overflow on the internal layer jar overflow coaming plate, because outer feed flow gets into from internal layer jar top; So can not have influence on the density that the sand glue is stirred in the bottom, thereby guarantee the stability of emission intensity; After stopping operation, intercommunicating pore can make outer jar liquid flow in the internal layer jar, has reduced the corrosion of outer feed flow to outer jar, the service life of having improved blending tank.Also saved outer jar blowdown, the Pneumatic butterfly valve first that therefore only is provided with through bottom, jar center just can be discharged remaining liquid and cleaning mixing sand tank.

The specific embodiment

Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.

A kind of double-deck mixing sand tank comprises outer jar, internal layer jar and blowdown apparatus, is evenly equipped with six intercommunicating pores 29 between said outer jar and the internal layer jar.

Outer jar is formed by tank body closure plate 1, outer cylinder 7, peripheral board 10, base plate first 11,15 weldings of water conservancy diversion baffle ring; The internal layer jar then is earlier steel plate ring 2 to be soldered to water fender 3; Be uniformly distributed with 48 gusset first 4 of welding for 2 times in steel plate ring again; On overflow coaming plate 6, be uniformly distributed with 24 gusset second 5 of welding then; With overflow coaming plate 6 and the inner cylinder that is uniformly distributed with welding overhead gage 98 welding, gusset first 4 and corresponding gusset second 5 are welded up and down form the internal layer jar so more again; Then, the internal layer jar is placed outer jar inside,, be welded with inner shield ring 28 on outer cylinder 7 inwalls between said outer cylinder 7 and the inner cylinder 8 inner cylinder 8 and peripheral board 10, water fender 3 and outer cylinder 7 welding.After water inlet pipe 26 was welded on the outer cylinder 7, then outer feed flow can get in outer jar through water inlet pipe 26 during operation, and flow in the tangential in outer jar.Inner shield ring 28 has reduced the kinetic energy of outer feed flow, makes it in outer jar after the circulation, and the radial hole that forms through 48 gusset first under the internal layer jar water fender 34 is got in the internal layer jar by 6 overflows of overflow coaming plate; This mode is the principle design that combines feed liquor liquid high surface area to add, and the mixing when therefore having guaranteed little sand ratio and float amount prevents inhomogeneous mixed sand glue.

For mixing sand tank is is conveniently installed and fixed, therefore on peripheral board 10, weld gusset the third 24, supporting leg 23, base plate second 22, otic placode 21 successively, can make mixing sand tank be installed in vehicle-mounted very easily like this or the sledge installing is equipped with.

The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
