Description

Technical Field

[0001] The invention belongs to the technical field of grouting, and in particular relates to a multi-slurry mixing device. Background Art

[0002] Grouting slurry is usually a mixture of water, cement and some other materials, rather than a single material. In the conventional grouting process, the slurry needs to be fully mixed in a mixer first, and then pressurized by a cement high-pressure pump for grouting. Although this method can fully mix the slurry, it needs to be introduced into the mixer first and then out of the mixer. The process is cumbersome and time-consuming when the amount of slurry is large.

[0003] Therefore, based on the above situation, it is necessary to invent a new type of multi-slurry mixing device. Summary of the invention

[0004] The main purpose of the present invention is to provide a multi-slurry mixing device, aiming to solve the problems of complicated, time-consuming and labor-intensive mixing procedures in existing mixers.

[0005] To this end, the multi-slurry mixing device provided by the present invention includes a spherical mixing chamber and a spherical rotor arranged in the spherical mixing chamber, the spherical mixing chamber is provided with a plurality of slurry injection inlets around the spherical rotor, the injection directions of the plurality of slurry injection inlets rotate counterclockwise or clockwise in the spherical mixing chamber to form a tangential circle, the slurry sprayed from the plurality of slurry injection inlets can drive the spherical rotor to rotate at a high speed in the spherical mixing chamber, and the spherical mixing chamber is also provided with a mixed slurry outlet on one side of the tangential circle.

[0006] Specifically, spherical grooves are evenly distributed on the outer surface of the spherical rotor.

[0007] Specifically, the slurry injection inlet is arranged at the side of the spherical mixing chamber, and the mixed slurry outlet is arranged at the bottom of the spherical mixing chamber.

[0008] Specifically, each of the slurry injection inlets is connected to a feed pipe, and the feed pipe is communicated with a high-pressure slurry source.

[0009] Specifically, during the high-speed rotation of the spherical rotor, the injection direction of the slurry injection inlet is tangent to the spherical rotor.

[0010] Specifically, the outer surface of the spherical rotor is plated with a wear-resistant coating.

[0011] Specifically, the wear-resistant coating is a hard alloy layer.

[0012] Compared with the prior art, at least one embodiment of the present invention has the following beneficial effects: a spherical rotor is provided in the spherical mixing chamber, and the high-pressure slurry sprayed from multiple slurry injection inlets drives the spherical rotor to rotate at a high speed in the spherical mixing chamber, thereby achieving mixing between the slurries, and the mixed slurry after mixing is automatically discharged from the mixed slurry outlet. The entire mixing structure is not only simple in structure, but also solves the problems of complicated mixing procedures, time-consuming and labor-intensive mixing processes of the mixer.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0020] See also Figure 1 and Figure 2 A multi-slurry mixing device includes a spherical mixing chamber 1 and a spherical rotor 2 arranged in the spherical mixing chamber 1. A plurality of slurry injection inlets 3 are arranged around the spherical rotor 2 on the spherical mixing chamber 1. The injection directions of the plurality of slurry injection inlets 3 rotate counterclockwise or clockwise in the spherical mixing chamber 1 to form a tangential circle. The slurry sprayed from the plurality of slurry injection inlets 3 can drive the spherical rotor 2 to rotate at a high speed in the spherical mixing chamber 1. A mixed slurry outlet 4 is also arranged on one side of the tangential circle on the spherical mixing chamber 1.

[0021] The working process of the mixing device of the above structure is as follows: the high-pressure slurry to be mixed is sprayed into the spherical mixing chamber 1 in a high-pressure state through multiple slurry injection inlets 3, and flushes the spherical rotor 2, driving the spherical rotor 2 to rotate at a high speed in the high-pressure slurry, thereby completing the mixing of the slurry. The mixed slurry maintains a high-pressure state and rushes out from the mixed slurry outlet 4 on the spherical mixing chamber 1. The entire mixing structure is not only simple in structure, but also solves the problems of complicated, time-consuming and labor-intensive mixing procedures of the mixer.

[0022] In some embodiments, spherical grooves are evenly distributed on the outer surface of the spherical rotor 2. Such a design can increase friction and thus accelerate the rotation of the spherical rotor 2, and can enhance the mixing effect.

[0023] See also Figure 2 Specifically, the slurry injection inlet 3 is arranged on the side of the spherical mixing chamber 1, and the mixed slurry outlet 4 is arranged at the bottom of the spherical mixing chamber 1. Each slurry injection inlet 3 is connected to a feed pipe, and the feed pipe is connected to a high-pressure slurry source.

[0024] In this embodiment, during the high-speed rotation of the spherical rotor 2, the injection direction of the slurry injection inlet 3 is tangent to the spherical rotor 2. The grouting materials that need to be mixed are first pressurized by a high-pressure pump and then enter the spherical mixing chamber through different feed pipes. The amount of each slurry can be adjusted by adjusting the pressure of the high-pressure pump. The pressurized slurry rushes into the spherical mixing chamber at high speed from different directions. Due to the particularity of the direction of the slurry injection inlet 3, the spherical rotor 2 will be subjected to several tangential forces in the same direction under the action of high pressure, so it rotates rapidly, thereby completing the mixing of the slurry; the mixed slurry maintains a high-pressure state and rushes out from the outlet at the lower part of the spherical mixing chamber for subsequent grouting work.

[0025] In addition, it should be explained that, in order to improve the erosion resistance of the spherical rotor 2 , a wear-resistant coating such as a hard alloy layer is plated on the outer surface of the spherical rotor 2 .

[0026] Unless otherwise stated, any technical solution disclosed in the present invention disclosed above, if it discloses a numerical range, then the disclosed numerical range is a preferred numerical range, and any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many implementable numerical values. Since there are too many numerical values ​​to be exhaustive, the present invention discloses some numerical values ​​to illustrate the technical solution of the present invention, and the numerical values ​​listed above should not constitute a limitation on the scope of protection of the present invention.

[0027] At the same time, if the above-mentioned invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0028] In addition, the terms used in any technical solution disclosed in the present invention to indicate positional relationships or shapes include states or shapes that are similar, similar or close to them unless otherwise stated. Any component provided by the present invention may be assembled from multiple separate components or may be a separate component manufactured by an integrated molding process.

[0029] The above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods.
