Description

Technical Field

[0001] The utility model relates to the technology of defoaming and noise reduction for high-pressure jet fluid, in particular to a defoaming and noise reduction device for high-pressure jet fluid. Background Art

[0002] Currently, in the fields of medicine, chemical industry, environmental protection and oil and gas exploitation, rapid and uniform mixing of powder and liquid is usually required. For example, in oil and gas exploitation, the preparation of flooding agents and fracturing fluids, etc. Currently, a jet mixer can be used for powder-liquid mixing. By introducing high-pressure jet fluid into the liquid inlet of the jet mixer and introducing powder into the feed inlet of the jet mixer, the jet mixer can utilize the Venturi effect to suck the powder at the feed inlet into the jet mixer for mixing.

[0003] After the existing jet mixer mixes by introducing high-pressure jet fluid, the solution is prone to generate foam, which is not convenient for foam elimination, affecting the solution quality. Moreover, the jet mixer is prone to generate relatively large noise during mixing, causing a greater impact on the staff. Content of the Utility Model

[0004] The purpose of the utility model is to provide a defoaming and noise reduction device for high-pressure jet fluid, which is used to solve the problems that after the existing jet mixer mixes by introducing high-pressure jet fluid, the solution is prone to generate bubbles or foam, which is not convenient for bubble elimination, and the jet mixer is prone to generate relatively large noise during mixing.

[0005] To solve the above problems, the utility model provides a defoaming and noise reduction device for high-pressure jet fluid, including a jet mixer body. The liquid outlet of the jet mixer body is threadedly connected with a defoaming pipe. A rotatable conical hopper is arranged in the defoaming pipe. A plurality of defoaming holes are formed in the conical hopper. The conical head of the conical hopper faces the jet mixer body. A plurality of inclined plates arranged in an annular array are fixedly connected to the conical head of the conical hopper. Sound insulation cotton is laid on the surfaces of the jet mixer body and the defoaming pipe.

[0006] The defoaming and noise reduction device for high-pressure jet fluid provided by the utility model also has the following technical features:

[0007] Further, a rotating ring is rotatably connected in the defoaming pipe. A cross rod is fixed to the inner side of the rotating ring. A rotating rod is rotatably connected to the middle of the cross rod. One end of the rotating rod is fixedly connected to the conical head of the conical hopper.

[0008] Further, the defoaming holes are arranged in a horn shape.

[0009] Further, a positioning ring is fixed to the edge of the conical hopper. A plurality of through holes arranged in an annular array are formed in the positioning ring.

[0010] Further, the edge of the conical hopper is fixedly connected to the rotating rod through a plurality of connecting rods.

[0011] Further, a first protective shell and a second protective shell are respectively arranged above and below the ejector body. The first protective shell and the second protective shell are connected by bolts, and the sound insulation cotton is wrapped between the first protective shell and the second protective shell.

[0012] The utility model has the following beneficial effects: By introducing powder into the feed inlet of the ejector body and introducing high-pressure jet fluid into the liquid inlet of the ejector body, the ejector body can utilize the Venturi effect to suck the powder at the feed inlet into the ejector for mixing. Since air is easily sucked in during the process of sucking the powder, foam is likely to be generated, which affects the quality of the solution. The solution carrying foam after mixing can enter the defoaming pipe through the liquid outlet of the ejector body. The solution drives the conical hopper to rotate through multiple inclined plates, and through the arrangement of the defoaming holes on the conical hopper, when the solution and foam pass through the defoaming holes, a compressive force and an impact force can be generated on the bubbles, which can break the foam film, thereby achieving the purpose of defoaming. Moreover, the rotatable setting of the conical hopper can achieve a better defoaming effect. Through the setting of the sound insulation cotton, noise can be effectively absorbed, reflected and dissipated, reducing the propagation of noise, thus avoiding causing a greater noise impact on the staff.

A plurality of inclined plates 4 arranged in an annular array are fixedly connected to the conical head of the conical hopper 3. Sound-absorbing cotton 5 is laid on the surfaces of the jet body 1 and the defoaming pipe 2. By introducing powder into the feed port of the jet body 1 and high-pressure jet fluid into the liquid inlet of the jet body 1, the jet body 1 can utilize the Venturi effect to suck the powder at the feed port into the jet for mixing. Since air is easily sucked in during the process of sucking the powder, foam is likely to be generated, which affects the solution quality. The solution carrying foam after mixing can enter the defoaming pipe 2 through the liquid outlet of the jet body 1. The solution drives the conical hopper 3 to rotate through the plurality of inclined plates 4. And through the arrangement of the defoaming holes on the conical hopper 3, when the solution and foam pass through the defoaming holes, a compressive force and an impact force can be generated on the bubbles, which can break the foam film, thereby achieving the purpose of defoaming. And the rotatable setting of the conical hopper 3 can achieve a better defoaming effect. Through the setting of the sound-absorbing cotton 5, noise can be effectively absorbed, reflected and dissipated, reducing the propagation of noise, so as to avoid causing a greater noise impact on the staff.

[0024] Defoaming is to take certain measures to break the formed foam or reduce the thickness of the foam layer. There are many common defoaming methods, which can be classified into physical defoaming method, mechanical defoaming method, chemical defoaming method and natural defoaming method according to the principle. The rupture of bubbles is to break the film forming the bubbles. Therefore, the bubbles are often compressed or impacted. By using the rapid change of pressure such as shear force, compression force and impact force, etc., the bubble film can be broken to achieve the purpose of defoaming. According to its characteristics of acting on the foam, it can be divided into centrifugal method, hydrodynamic method, aerodynamic method, compression method and impact method, etc.

[0025] When the utility model is in use, powder is introduced into the feed port of the injector body 1, and high-pressure jet fluid is introduced into the liquid inlet of the injector body 1, so that the injector body 1 can use the Venturi effect to suck the powder at the feed port into the injector for mixing. Since air is easily sucked in during the process of sucking the powder, foam is easily generated, which affects the quality of the solution. The solution carrying foam after mixing can enter the defoaming pipe 2 through the liquid outlet of the injector body 1. The rotating ring 6 can facilitate the rotation of the conical hopper 3, and the cross bar 7 plays a supporting role for the rotating rod 8. The solution drives the conical hopper 3 to rotate through a plurality of inclined plates 4, and through the arrangement of the defoaming holes on the conical hopper 3, when the solution and the foam pass through the defoaming holes, a compression force and an impact force can be generated on the bubbles, the bubble film can be broken, and thus the purpose of defoaming can be achieved. Moreover, the rotatable setting of the conical hopper 3 can achieve a better defoaming effect. The sound insulation cotton 5 can effectively absorb, reflect and dissipate noise, reduce the transmission of noise, and thus avoid causing great noise impact on the staff.
