Description

Technical Field

[0001] The utility model relates to the technical field of cement slurry mixing, and particularly relates to a three-way pipe of a grouting machine and a grouting machine. Background Art

[0002] Cement is a commonly used building material, which is a powdery substance mainly made from limestone, clay and other auxiliary materials through processes such as calcination and grinding. When cement is mixed with water, a chemical reaction occurs to form a gelling substance, thus generating a slurry-like substance, namely cement slurry. And water glass, also known as sodium silicate, is an inorganic compound with the chemical name of sodium orthosilicate. It is a colorless or light yellow liquid with a viscous property.

[0003] In order to enhance the performance and characteristics of cement slurry, water glass can be quantitatively added into the cement slurry. By adding water glass into the cement slurry, the bonding force of the cement slurry can be enhanced, the impermeability of the cement slurry can be improved, the durability of the cement slurry can be increased, and the fluidity of the cement slurry can be improved.

[0004] When mixing cement slurry and water glass, a three-way pipe is mostly used for mixing, that is, the cement slurry and water glass are simultaneously injected into the three-way pipe, and then the discharged slurry from the three-way pipe is the mixed slurry. However, the cement slurry and water glass mixed only through the three-way pipe are mostly unevenly mixed, thereby affecting the performance of the cement (such as strength, bonding force, waterproofness, etc.).

[0005] In view of this, this patent application is proposed. Summary of the Utility Model

[0027] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the embodiments and the accompanying drawings. The illustrative embodiments and descriptions thereof of the present utility model are only used to explain the present utility model and are not intended to limit the present utility model.

[0028] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present utility model. However, it is obvious to those of ordinary skill in the art that: It is not necessary to adopt these specific details to implement the present utility model.

[0029] Throughout the specification, the reference to "an embodiment", "embodiment", "an example" or "example" means that: the specific features, structures or characteristics described in conjunction with the embodiment or example are included in at least one embodiment of the present utility model. Therefore, the phrases "an embodiment", "embodiment", "an example" or "example" appearing throughout the specification do not necessarily all refer to the same embodiment or example. In addition, the specific features, structures or characteristics can be combined in any appropriate combination and / or sub-combination in one or more embodiments or examples. In addition, those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0030] In the description of the present utility model, the orientation or positional relationship indicated by terms such as "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "high", "low", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0031] As Figures 1 to 5 shown in, a three-way pipe of a grouting machine includes a three-way pipe body 1. The three-way pipe body 1 has two feed ports and one discharge port, forming a T-shaped structure. The two feed ports of the three-way pipe body 1 are respectively connected to a sodium silicate source and a cement slurry source. A sealed housing 8 is provided at the discharge port of the three-way pipe body 1. A cavity is provided inside the sealed housing 8. A stirring mechanism 3 is provided in the cavity of the sealed housing 8 for stirring the incoming materials. A discharge pipe 9 is connected to the outlet of the sealed housing 8.

[0032] After the cement slurry and sodium silicate are mixed, sodium silicate can chemically react with cement to form a gelling substance, thereby enhancing the bonding force of the cement slurry and improving the adhesiveness and viscosity of the material. The addition of sodium silicate can also improve the anti-seepage performance of the cement slurry, making it form a relatively dense structure after curing and reducing water penetration. The hardening process of sodium silicate can improve the durability of the cement slurry, making it more weather-resistant, chemically corrosion-resistant, and wear-resistant. At the same time, the addition of sodium silicate can also improve the fluidity of the cement slurry, making it easier to construct and fill small voids.

[0033] However, the cement slurry and sodium silicate entering the three-way pipe body 1 for mixing may have uneven mixing, that is, the sodium silicate content in the cement slurry is different. As a result, after the mixed slurry formed by the cement slurry and sodium silicate solidifies, the properties such as the strength, bonding force, and waterproofness of the cement are poor.

[0034] To solve the above problems, in this embodiment, a stirring mechanism 3 is provided at the discharge port of the three-way pipe body 1. During use, sodium silicate and cement slurry enter through the two feed ports of the three-way pipe body 1. The cement slurry and sodium silicate entering the three-way pipe body 1 come into contact and impact to produce mixing. Then when flowing out, they flow into the cavity of the sealed housing 8. Relying on the stirring mechanism 3 to stir the incoming mixed slurry is conducive to the uniform mixing of the two, thereby improving the problem of uneven mixing of the existing sodium silicate and cement slurry and improving the performance of the outflowing mixed slurry.

[0035] Further, the stirring mechanism 3 includes a runner 31 and blades 32. The middle of the runner 31 has a central axle. Both ends of the central axle are fixedly connected to the sealed housing 8. The runner 31 is rotationally matched with the central axle. A plurality of blades 32 are fixedly arranged on the outer peripheral surface of the runner 31 and are distributed in a circumferential array. When the sodium silicate and the cement slurry enter the sealed housing 8, with the flow of the sodium silicate and the cement slurry, the runner 31 is driven to rotate. By relying on the rotation of the blades 32, the incoming slurries are stirred, so as to achieve the purpose of mixing.

[0036] Preferably, two runners 31 are provided and are distributed side by side. The blades 32 of the two runners 31 are arranged in an intersecting and meshing manner. The mixed slurry entering the sealed housing 8 through the feed port will impact the intersecting blades 32. The blades 32 are driven by the thrust of the mixed slurry to drive the runner 31 to rotate, and the two runners 31 rotate in opposite directions, thereby realizing stirring. The uniformly mixed slurry can increase the strength and durability of the cement, improve the waterproof performance of the cement, improve the fluidity of the cement, and increase the fire resistance of the cement.

[0037] Preferably, the sealed housing 8 has a structure with a large end and a small end. The end close to the three-way pipe body 1 is the large end, and the end close to the discharge pipe 9 is the small end. The mixed slurry after stirring will be compressed at the small end, which will increase the outflow speed of the slurry.

[0038] Furthermore, before the mixed slurry enters the sealed housing 8, in order to preliminarily mix the cement slurry and the sodium silicate, a slurry mixing pipe is provided between the sealed housing 8 and the three-way pipe body 1. A rotating ring 71 is arranged in the slurry mixing pipe. A plurality of guide plates 72 are arranged in the rotating ring 71. The rotating ring 71 is rotationally connected and matched with the inner side wall of the slurry mixing pipe; each of the guide plates 72 is an arc-shaped plate. One end of each guide plate 72 is connected, and the other end is fixedly connected to the rotating ring 71. The included angle between each adjacent two guide plates 72 is equal, forming a structure in which a plurality of guide plates 72 are evenly distributed in a circular array with the rotating ring 71 as the center. When the mixed slurry contacts the surface of the guide plate 72, the rotating ring 71 is driven to rotate in the mixing pipe 7. The multiple portions of the mixed slurry discharged by rotation can be preliminarily mixed and then introduced into the sealed housing 8.

[0039] Embodiment 2:

[0040] A grouting machine, as Figure 1As shown, it includes the three-way pipe of the grouting machine in Embodiment 1, and discharge pipes 2 are connected to the two feed ports of the three-way pipe body 1. Connecting pipes 4 are respectively connected to the inlets of the discharge pipes 2, and the inlets of the connecting pipes 4 are connected to feed pipes, and the feed pipes are respectively connected to the sodium silicate source and the cement slurry source. Sodium silicate and cement slurry respectively enter the connecting pipes 4 from the feed pipes, then enter the feed pipes and finally enter the three-way pipe body 1. And the two connecting pipes 4 are both installed outside the pump truck 5, and branch pipes are provided on the connecting pipes 4 to communicate with the pump truck 5. Among them, the pump truck 5 refers to the grouting machine of model YAB-500. There are two cavities in the pump truck 5, which are respectively used to accommodate sodium silicate and cement slurry, and a pump is provided in each cavity. By operating the pump, the internal pressure of the connecting pipe 4 is increased, and then the cement slurry or sodium silicate entering the connecting pipe 4 is injected into the discharge pipe 2 to control the flow of the liquid.

It should be understood that the above are only the specific implementation manners of the present invention and are not used to limit the protection scope of the present invention.
