Description

Technical Field

[0001] This invention relates to the technical field of mixing foaming liquids and foam stabilizing liquids, and specifically to a foam liquid mixing box. Background Technology

[0002] The foaming liquid mixing tank is a key component of the foamed cement slurry generating device. Its function is to store a certain amount of mixture of foaming liquid and foam stabilizing liquid, which is then pumped to conventional cement slurry for mixing to produce foamed cement slurry. Generally, the mixing tank needs to be filled with a certain amount of foaming liquid and foam stabilizing liquid. These two often cannot be mixed very evenly within the tank, requiring the impeller agitator inside the tank to stir them uniformly. Sometimes, different types of foaming liquid and foam stabilizing liquid, when mixed separately, can cause sedimentation, further necessitating timely stirring. However, during stirring, a large amount of foam inevitably appears on the liquid surface. This large amount of foam increases rapidly with stirring, eventually overflowing the tank and contaminating the equipment and well site, which is unacceptable in on-site construction. To avoid excessive foam, one solution is to use an impeller agitator in the existing foaming liquid tank with an excessively low stirring speed. Sometimes, if the tank is overfilled, stirring may even fail. This prevents the foaming and stabilizing liquids in the tank from being fully and evenly mixed, leading to poor foaming and stabilizing quality and uneven foam after subsequent mixing with cement slurry.

[0003] Therefore, how to provide a mixing tank that helps to fully mix the foaming liquid and foam stabilizing liquid while adding foaming liquid and foam stabilizing liquid into the foaming liquid mixing tank, and effectively suppresses the bubble layer on the liquid surface to prevent it from overflowing out of the tank, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a mixing tank that helps to fully mix the foaming liquid and foam stabilizing liquid while adding foaming liquid and foam stabilizing liquid into the foaming liquid mixing tank, and effectively suppresses the bubble layer on the liquid surface to prevent it from overflowing out of the tank.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A foam liquid mixing tank, comprising:

[0007] A box with an open opening and an internal chamber, wherein a rotatable stirring impeller is installed in the chamber, and a foaming liquid injection port, a foam stabilizing liquid injection port, and a drain port are provided on the box and connected to the chamber;

[0008] An antifoaming liquid permeator made of absorbent material is located above the stirring impeller in the chamber. The antifoaming liquid permeator has a lower contact plane whose area matches the area of ​​the opening of the housing.

[0009] An antifoaming liquid injection port, located above the antifoaming liquid permeator, is used to supply antifoaming liquid.

[0010] In use, foaming liquid and foam stabilizing liquid are injected into the chamber through the foaming liquid injection port and the foam stabilizing liquid injection port. After being stirred by the stirring impeller, foam liquid and a bubble layer are formed above the foam liquid. The lower contact plane contacts the bubble layer. The defoaming liquid permeator is in a state of being wetted with defoaming liquid, so that defoaming liquid is attached to the lower contact plane and the defoaming liquid does not drip into the foam liquid.

[0011] Preferably, the defoaming liquid permeator includes a belt, and rotating rollers are rotatably installed on opposite sides of the housing. The belt is mounted on the two rotating rollers and can rotate with the rollers. When the belt rotates, the downward rotating surface of the belt forms the lower contact plane, and the defoaming liquid injection port is located above the upper rotating surface of the belt.

[0012] Preferably, the upper and lower rotating surfaces of the belt are filled with an antifoaming liquid containing layer, which is a containing layer made of water-absorbing material.

[0013] Preferably, a metal partition fixedly connected to the box body is provided above and below the defoaming liquid layer, and several permeation holes are opened on the metal partition.

[0014] Preferably, the system also includes a defoaming liquid box capable of storing defoaming liquid, the defoaming liquid box being fixed to the inner wall of the box and located above the belt, the defoaming liquid box having an outlet that forms the defoaming liquid injection port.

[0015] Preferably, the outlet is filled with a filler made of absorbent material, which contacts the belt.

[0016] Preferably, the drain outlet is located at the bottom of the housing.

[0017] Preferably, a level gauge is also included, which is installed in the chamber.

[0018] Preferably, a cover plate is also included, which is hinged to the open end of the housing.

[0019] Preferably, the device also includes a motor, which is mounted on the outside of the bottom end of the housing, and the output shaft of the motor is connected to the stirring shaft of the stirring impeller.

[0020] Technical effects:

[0021] The chamber is equipped with a defoaming liquid permeator made of absorbent material. During use, foaming liquid and foam stabilizing liquid are injected into the chamber through the foaming liquid injection port and the foam stabilizing liquid injection port. After being stirred by the stirring impeller, foam liquid and a bubble layer are formed on top of the foam liquid. The defoaming liquid permeator is in a state of being wetted with defoaming liquid, so that the lower contact surface is covered with defoaming liquid and the defoaming liquid does not drip into the foam liquid. The lower contact surface of the defoaming liquid contacts the bubble layer, which can eliminate bubbles and consume some defoaming liquid at the same time. The defoaming liquid permeator continuously permeates the defoaming liquid to the lower contact surface to continuously eliminate bubbles generated during stirring. By controlling the injection amount of defoaming liquid, the lower contact surface is covered with defoaming liquid and the defoaming liquid does not drip into the foam liquid, thereby avoiding contamination of the foam liquid formed by stirring by the defoaming liquid.

[0022] Preferably, a belt is used. During use, the belt rotates, and the defoaming liquid slowly leaks through the defoaming liquid injection port to the upper rotating surface of the belt. After the upper rotating surface is coated with defoaming liquid, it is transported over a long distance. After reaching the other side of the box, it is reversed by a rotating roller and becomes the lower rotating surface, i.e., the lower contact plane. When the bubble layer comes into contact with the defoaming liquid on the lower contact plane, it is eliminated, which can effectively inhibit the growth of the bubble layer. Finally, a suitable impeller speed and belt speed can be determined so that the bubble layer generated when the impeller is fully agitating can be suppressed in time by the defoaming liquid on the belt, preventing the bubble layer and foam liquid from overflowing out of the box.

[0023] Preferably, a defoaming liquid containing layer is filled between the upper and lower rotating surfaces of the belt. This defoaming liquid containing layer is made of absorbent material. This design allows excess defoaming liquid dripping onto the belt to permeate into the defoaming liquid containing layer, preventing the belt from carrying excessive defoaming liquid that could then fall into the foaming liquid and contaminate it.

[0024] Preferably, a metal partition is provided to stabilize and fix the defoamer-containing layer.

[0025] Preferably, the outlet is filled with a filler made of absorbent material. The outlet makes slight contact with the belt through this filler. When the belt is running, the defoaming liquid flows from the defoaming liquid box and adheres to the belt. When the belt is not running, the defoaming liquid will not continuously flow from the outlet, but there will still be some leakage; this consumption is very small and negligible. If the belt is not used for a long period, the defoaming liquid in the defoaming box should be emptied. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in further detail.

[0032] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving the beneficial effects of the invention. Therefore, the following description should be understood as being of broad knowledge to those skilled in the art and is not intended to limit the invention.

[0033] For clarity, not all features of the actual embodiments are described. In the following description, well-known functions and structures are not detailed in detail, as they would confuse the invention with unnecessary detail. It should be understood that in the development of any actual embodiment, numerous implementation details must be made to achieve the developer's specific objectives.

[0034] To make the objectives and features of the present invention more apparent and understandable, the specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, intended only to facilitate and clearly illustrate the objectives of the embodiments of the present invention.

[0035] Combination Figure 1-3 The present invention provides a foam liquid mixing tank, which includes:

[0036] A box 1 with an open opening and an internal chamber, wherein a rotating stirring impeller 2 is installed in the chamber, and a foaming liquid injection port 3, a foam stabilizing liquid injection port 4, and a drain port 5 are provided on the box 1 and connected to the chamber.

[0037] An antifoaming liquid penetrating body 6, made of absorbent material, is located above the stirring impeller 2 in the chamber. The antifoaming liquid penetrating body 6 has a lower contact plane 9, the area of ​​which matches the area of ​​the opening of the housing 1.

[0038] The defoaming liquid injection port is located above the defoaming liquid permeator 6 and is used to supply defoaming liquid.

[0039] In use, foaming liquid and foam stabilizing liquid are injected into the chamber through the foaming liquid injection port 3 and the foam stabilizing liquid injection port 4. After being stirred by the stirring impeller 2, foam liquid 10 and a bubble layer 11 above the foam liquid 10 are formed. The lower contact plane 9 contacts the bubble layer 11. The defoaming liquid penetrating body 6 is in a state of being wetted with defoaming liquid, so that defoaming liquid is attached to the lower contact plane 9 and the defoaming liquid does not drip into the foam liquid 10.

[0040] The chamber is equipped with a defoaming liquid permeator 6 made of absorbent material. During use, foaming liquid and foam stabilizing liquid are injected into the chamber through the foaming liquid injection port 3 and the foam stabilizing liquid injection port 4. After being stirred by the stirring impeller 2, foam liquid 10 and a bubble layer 11 above the foam liquid 10 are formed. The defoaming liquid permeator 6 is in a state of being wetted with defoaming liquid, so that the lower contact plane 9 is covered with defoaming liquid and the defoaming liquid does not drip into the foam liquid 10. The lower contact plane 9 with defoaming liquid contacts the bubble layer 11, which can eliminate bubbles and consume some defoaming liquid at the same time. The defoaming liquid permeator 6 continuously permeates defoaming liquid to the lower contact plane 9 to continuously eliminate bubbles generated during stirring. By controlling the injection amount of defoaming liquid, the lower contact plane 9 is covered with defoaming liquid and the defoaming liquid does not drip into the foam liquid, thereby avoiding contamination of the foam liquid 10 formed by stirring by the defoaming liquid.

[0041] In one specific implementation, combined with Figure 1-2 The defoaming liquid penetrator 6 includes a belt 7. Rotating rollers 8 are rotatably installed on opposite sides of the housing 1. The belt 7 is mounted on the two rotating rollers 8 and can rotate with the rotating rollers 8. When the belt 7 rotates, the downward rotating surface of the belt 7 forms the lower contact plane 9. The defoaming liquid injection port is located above the upper rotating surface of the belt 7.

[0042] The belt 7 is installed. When in use, the belt 7 rotates, and the defoaming liquid slowly leaks through the defoaming liquid injection port to the upper rotating surface of the belt 7. After the upper rotating surface is coated with the defoaming liquid, it is transported along a long distance. After reaching the other side of the box 1, it is reversed by the rotating roller 8 and becomes the lower rotating surface, namely the lower contact plane 9. When the bubble layer 11 comes into contact with the defoaming liquid on the lower contact plane 9, it is eliminated, which can effectively inhibit the growth of the bubble layer. Finally, a suitable speed of stirring impeller 2 and belt 7 can be determined so that the bubble layer generated when stirring impeller 2 is fully stirring can be suppressed in time by the defoaming liquid on belt 7, preventing the bubble layer and foam liquid from overflowing out of the box.

[0043] In one specific implementation, such as Figure 1-3As shown, the upper rotating surface and the lower rotating surface of the belt 7 are filled with a defoaming liquid containing layer 12, which is a containing layer made of water-absorbing material.

[0044] A defoaming liquid containing layer 12 is filled between the upper and lower rotating surfaces of the belt 7. The defoaming liquid containing layer 12 is made of absorbent material. This arrangement allows excess defoaming liquid dripping onto the belt 7 to penetrate into the defoaming liquid containing layer 12 through the belt 7, preventing the belt 7 from carrying too much defoaming liquid and causing it to fall into the foam liquid 10 and contaminate the foam liquid 10.

[0045] like Figure 3 As shown, a metal partition 13 is fixedly connected to the box body 1 above and below the defoaming liquid containing layer 12, and several permeation holes are opened on the metal partition 13.

[0046] A metal partition 13 is provided to stabilize and fix the defoaming liquid containing layer 12.

[0047] like Figure 1 As shown, in one specific embodiment, it also includes a defoaming liquid box 14 capable of storing defoaming liquid. The defoaming liquid box 14 is fixed on the inner wall of the box body 1 and located above the belt 7. The defoaming liquid box 14 has an outlet 15, which forms the defoaming liquid injection port.

[0048] Furthermore, the outlet 15 is filled with a filler made of absorbent material, which contacts the belt 7.

[0049] The outlet 15 is filled with a filler made of absorbent material. The outlet 15 makes slight contact with the belt 7 through this filler. When the belt 7 is running, the defoaming liquid can flow out from the defoaming liquid box 14 and adhere to the belt 7. When the belt 7 is not running, the defoaming liquid in the outlet 15 will not flow continuously, but there will still be some leakage, which is very small and negligible. If the belt 7 is not used for a long time, the defoaming liquid in the defoaming liquid box 14 should be emptied.

[0050] In one specific implementation, such as Figure 1 As shown, the drain port 5 is located at the bottom of the housing 1, and also includes a filter screen disposed at the drain port 5.

[0051] Furthermore, it also includes a level gauge 16, which is installed in the chamber.

[0052] like Figure 1 As shown, it also includes a cover plate 17, which is hinged to the open end of the box body 1. The rotatable cover plate 17 is provided to facilitate observation of the situation inside the box body 1.

[0053] In one specific embodiment, a motor 18 is also included, which is installed on the outside of the bottom end of the housing 1, and the output shaft of the motor 18 is connected to the stirring shaft of the stirring impeller 2.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention; therefore, the above descriptions are merely embodiments of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only principles of the present invention. The present invention also includes various equivalent changes and modifications without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
