Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a hydraulic jet mud mixer. Background Technology

[0002] Mud mixers are currently mainly mechanical rotary mixing mud mixers such as scraper type, blade type or auger type. Their structure is mainly based on the use of electric device to drive the scraper, blade or auger installed in the container to rotate, so that the clay or bentonite added to the container is mixed with water into mud.

[0003] However, the blades of existing mud mixers are in direct contact with solid particles, resulting in severe wear. Furthermore, the drive shaft and mud tank are sealed with rubber rings, which have a short lifespan and require regular replacement, leading to high maintenance costs. Additionally, due to the fixed working radius of the blades, dead zones that cannot be mixed are easily created, thus affecting mud performance, such as uneven viscosity and density. Utility Model Content

[0004] This utility model provides a hydraulic jet mud mixer to solve the problems of existing mud mixers where the blades are in direct contact with solid particles, resulting in severe wear; the transmission shaft and mud tank are sealed with rubber rings, leading to a short lifespan, the need for regular replacement, and high maintenance costs; and the fixed working radius of the blades can easily create dead zones that are not mixed, thus affecting the mud performance. The present invention achieves a mud mixer with no mechanical wear, a longer service life, and lower maintenance costs; at the same time, it can achieve efficient mixing, significantly improving the solid dispersion efficiency.

[0005] This utility model provides a hydraulic jet type mud mixer, comprising:

[0006] A mud tank having a stirring chamber;

[0007] A jet nozzle is disposed at the bottom of the stirring chamber and jets a stream toward the stirring chamber;

[0008] A mud circulation loop is provided, with one end connected to the jet nozzle and the other end connected to the upper middle part of the mixing chamber. The mud circulation loop is used to transport the upper middle layer of mud medium in the mixing chamber to the jet nozzle, and then jet the medium into the mixing chamber through the jet nozzle.

[0009] A mud pump is provided on the mud circulation loop and is used to pump the mud medium in the mud circulation loop to the jet nozzle.

[0010] According to the present invention, a water jet type mud mixer is provided, wherein the nozzle is arranged tangentially to the bottom circumference of the mixing chamber.

[0011] According to the present invention, a hydraulic jet mud mixer is provided, which also includes a first valve. The first valve is located at the end of the mud circulation loop connected to the jet nozzle. The first valve is used to control the start and stop of the jet nozzle and to control the jet speed of the jet nozzle by adjusting its own opening.

[0012] According to the present invention, a hydraulic jet mud mixer includes a mud circulation loop comprising a riser section, a suction pipeline section, and a high-pressure pipeline section. The riser section is vertically disposed within the mixing chamber, with its upper end extending to the upper-middle part of the mixing chamber. The lower end of the riser section is connected to one end of the suction pipeline section through an opening in the mud tank. The other end of the suction pipeline section is connected to the inlet of the mud pump. The high-pressure pipeline is connected between the storage port of the mud pump and the jet nozzle.

[0013] According to the present invention, a hydraulic jet mud mixer is provided, wherein the outer peripheral wall of the riser section near its upper end is provided with multiple filter holes.

[0014] According to the present invention, a hydraulic jet mud mixer further includes a second valve, which is disposed between the riser section and the suction pipeline section.

[0015] According to the present invention, a hydraulic jet mud mixer is provided, wherein the mud tank is a cylindrical shape with an open top and a closed bottom.

[0016] According to the present invention, a hydraulic jet mud mixer further includes a cover plate, which is semi-circular in shape and covers one side of the upper opening of the mud tank.

[0017] According to the present invention, a hydraulic jet mud mixer further includes a density sensor, which is disposed in the mixing chamber and is connected to the mud pump for signal connection.

[0018] According to the present invention, a hydraulic jet mud mixer is provided, wherein there are multiple jet nozzles, and the multiple jet nozzles are evenly distributed along the circumference of the bottom of the mixing chamber.

[0019] This invention provides a hydraulic jet-type mud mixer that agitates mud by jetting a stream of water into the mixing chamber through a jet nozzle. The jet nozzle itself does not directly contact the solid particles in the mud; instead, it utilizes the impact force of the high-speed jet to drive the mud flow and mix. Therefore, it avoids the wear problems caused by direct contact between mechanical parts and solid particles in traditional mixers, achieving zero mechanical wear. Due to the absence of mechanical wear, the service life of key components such as the jet nozzle is significantly extended. Furthermore, since frequent replacement of worn parts is unnecessary, only periodic inspection and maintenance of a few components such as the jet nozzle are required, and the maintenance operation is relatively simple, greatly reducing equipment maintenance costs. Simultaneously, the upper and middle layers of mud in the mixing chamber are transported to the jet nozzle through a mud circulation loop, and then jetted into the mixing chamber. This circulating jet method causes the mud to be continuously re-intaked and ejected within the mixing chamber, forming strong turbulence and eddies. Under the intense impact and turbulence of the jet, the agglomeration structure between solid particles is rapidly broken down, and the collisions and friction between particles increase, thereby accelerating the dispersion process of solid particles in the liquid phase. Compared with traditional mechanical blade stirring, the impact shear force generated by the hydraulic jet is stronger, which can more effectively disperse solid particles into the liquid phase, significantly improving the solid dispersion efficiency. In addition, the circulating jet can continuously reintroduce insufficiently dispersed slurry into the jet region for re-stirring, further improving the uniformity and efficiency of solid dispersion.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0030] The following is combined Figure 1 The present invention provides a detailed description of a hydraulic jet mud mixer through specific embodiments and application scenarios.

[0031] In the embodiments of this utility model, such as Figure 1 As shown, the hydraulic jet mud mixer 10 includes a mud tank 100, a jet nozzle 200, a mud circulation loop 300, and a mud pump 400. The mud tank 100 has a mixing chamber 110. The jet nozzle 200 is located at the bottom of the mixing chamber 110 and jets towards the mixing chamber 110. One end of the mud circulation loop 300 is connected to the jet nozzle 200, and the other end is connected to the upper middle part of the mixing chamber 110. The mud circulation loop 300 is used to transport the upper middle layer of mud medium in the mixing chamber 110 to the jet nozzle 200, and jets it into the mixing chamber 110 through the jet nozzle 200. The mud pump 400 is located on the mud circulation loop 300 and is used to pump the mud medium in the mud circulation loop 300 to the jet nozzle 200.

[0032] The mud tank 100 is the basic container of the entire mixer, featuring a mixing chamber 110 that provides space for mud mixing and storage. It can hold the mud material to be mixed, as well as the mud formed during the mixing process, ensuring that the mixing operation takes place in a relatively closed and stable environment, preventing mud leakage to the external environment, and facilitating centralized treatment and subsequent use of the mud. This application also supports the parallel connection of multiple mud tanks 100 to meet the continuous mud supply requirements of large-scale construction projects.

[0033] The jet nozzle 200 is located at the bottom of the mixing chamber 110, which can make full use of the space of the mixing chamber 110 and drive the flow of mud throughout the mixing chamber 110. At the same time, the bottom position also helps to fully agitate the mud at the bottom of the mixing chamber 110 and prevent mud sedimentation. The jet nozzle 200 jets towards the mixing chamber 110, which can spray the mud medium delivered by the mud circulation loop 300 in the form of a high-speed jet. The high-speed jet has a large kinetic energy, which can impact and drive the surrounding mud medium, forming a strong agitation effect, breaking the agglomeration structure between solid particles in the mud, promoting the dispersion of solid particles in the liquid phase, and thus achieving efficient mixing of the mud.

[0034] In some embodiments, the jet nozzle 200 may be made of hard alloy, wear-resistant ceramic, wear-resistant alloy or rubber material to accommodate solid phases of different hardness.

[0035] One end of the mud circulation loop 300 is connected to the jet nozzle 200, and the other end is connected to the upper middle part of the mixing chamber 110. It serves to connect the jet nozzle 200 and the mixing chamber 110, forming a complete mud circulation system. The mud circulation loop 300 is used to transport the upper middle layer of mud medium in the mixing chamber 110 to the jet nozzle 200. During the mixing process, the upper middle layer of mud in the mixing chamber 110 may have already undergone some mixing, but it may not be uniform enough. By transporting this mud medium to the jet nozzle 200 through the mud circulation loop 300 for further jet mixing, the mud can be more thoroughly mixed. The mud circulation loop 300 realizes the circulation of mud within the mixing chamber 110, continuously reintroducing insufficiently mixed mud into the jet area for further mixing, avoiding the occurrence of dead zones in the mixing process, and improving the uniformity and efficiency of the mixing.

[0036] The mud pump 400 is located on the mud circulation loop 300 and serves as the power source for the entire mud circulation system. The mud pump 400 pumps the mud medium within the mud circulation loop 300 to the jet nozzle 200, providing sufficient pressure and power for the mud flow within the loop. This ensures that the mud can be smoothly transported from the upper part of the mixing chamber 110 to the jet nozzle 200, forming a high-speed jet. By adjusting the operating parameters of the mud pump 400, the flow rate and pressure of the mud in the circulation loop can be controlled, thereby adjusting the jet velocity and intensity of the jet nozzle 200 to adapt to different mud materials and mixing requirements, achieving precise control of the mixing process.

[0037] This application uses a jet nozzle 200 to jet the slurry into the mixing chamber 110. The jet nozzle 200 itself does not directly contact the solid particles in the slurry; instead, it utilizes the impact force of the high-speed jet to drive the slurry flow and mixing. Therefore, it avoids the wear problems caused by direct contact between mechanical parts and solid particles in traditional mixers, achieving zero mechanical wear. Due to the absence of mechanical wear, the service life of key components such as the jet nozzle 200 is significantly extended. Furthermore, since frequent replacement of worn parts is unnecessary, only periodic inspection and maintenance of a few components such as the jet nozzle 200 are required, and the maintenance operation is relatively simple, greatly reducing equipment maintenance costs. Simultaneously, the upper and middle layers of slurry medium in the mixing chamber 110 are transported to the jet nozzle 200 through the slurry circulation loop 300, and then jetted into the mixing chamber 110 by the jet nozzle 200. This circulating jet method causes the slurry to be continuously re-intaked and ejected within the mixing chamber 110, forming strong turbulence and eddies. Under the intense impact and turbulence of the jet, the agglomeration structure between solid particles is rapidly broken down, and the collisions and friction between particles increase, thereby accelerating the dispersion process of solid particles in the liquid phase. Compared with traditional mechanical blade stirring, the impact shear force generated by the hydraulic jet is stronger, which can more effectively disperse solid particles into the liquid phase, significantly improving the solid dispersion efficiency. In addition, the circulating jet can continuously reintroduce insufficiently dispersed slurry into the jet region for re-stirring, further improving the uniformity and efficiency of solid dispersion.

[0038] Reference Figure 1 According to the present invention, a water jet mud mixer 10 is provided, wherein the nozzle is arranged in the tangential direction of the bottom circumference of the mixing chamber 110.

[0039] Understandably, the vortex effect generated by the tangential jet enables the slurry to form a strong rotating flow within the mixing chamber 110. This rotating flow rapidly and thoroughly mixes the solid particles with the liquid, breaking down the agglomeration structure of the solid particles, increasing collisions and friction between particles, thereby accelerating the dispersion process of the solid particles in the liquid phase. Simultaneously, the vortex effect formed by the tangential jet covers the entire area within the mixing chamber 110, including the bottom and corners, avoiding the dead zones commonly found in traditional mixers. This ensures that the slurry remains uniformly distributed throughout the mixing process, improving the uniformity and efficiency of the mixing.

[0040] Reference Figure 1 According to the present invention, a hydraulic jet mud mixer 10 is provided, which also includes a first valve 500. The first valve 500 is located at one end of the mud circulation loop 300 connected to the jet nozzle 200. The first valve 500 is used to control the start and stop of the jet nozzle 200 and to control the jet speed of the jet nozzle 200 by adjusting its own opening.

[0041] Understandably, the spraying action of the jet nozzle 200 can be easily started or stopped by opening and closing the first valve 500. This allows the stirring process to be flexibly adjusted according to actual needs. Furthermore, different stirring tasks may require different jet velocities. By adjusting the opening of the first valve 500, the jet velocity of the jet nozzle 200 can be changed, thus adapting to different stirring requirements.

[0042] Reference Figure 1 According to the present invention, a hydraulic jet mud mixer 10 is provided, wherein the mud circulation loop 300 includes a riser section 310, a suction pipe section 320 and a high-pressure pipe section 330. The riser section 310 is arranged vertically in the mixing chamber 110, and the upper end of the riser section 310 extends to the upper middle part of the mixing chamber 110. The lower end of the riser section 310 is connected to one end of the suction pipe section 320 through an opening on the mud tank 100. The other end of the suction pipe section 320 is connected to the inlet of the mud pump 400. The high-pressure pipe is connected between the storage port of the mud pump 400 and the jet nozzle 200.

[0043] Understandably, a complete mud circulation path is constructed by connecting the riser section 310, the suction pipeline section 320, and the high-pressure pipeline section 330. This allows the mud to circulate between the mixing chamber 110, the mud pump 400, and the jet nozzle 200, achieving continuous stirring and mixing of the mud.

[0044] The suction pipeline section 320 is connected to the inlet of the mud pump 400 and is used to draw mud from the mixing chamber 110 into the mud pump 400; the high-pressure pipeline section 330 is connected to the storage port of the mud pump 400 and the jet nozzle 200 and is used to transport the high-pressure mud after being pressurized by the mud pump 400 to the jet nozzle 200; the riser section 310 is responsible for drawing mud from the middle and upper part of the mixing chamber 110 and transporting it to the suction pipeline section 320.

[0045] The upper end of the riser section 310 extends to the upper middle part of the mixing chamber 110 to ensure that mud is drawn from the upper middle part of the mixing chamber 110. Since the jet nozzle 200 is located at the bottom of the mixing chamber 110, the mud forms a top-to-bottom circulating flow in the mixing chamber 110, which helps to achieve uniform mixing of the mud and avoid the formation of dead zones in the mixing.

[0046] The high-pressure pipeline section 330, pressurized by the mud pump 400, delivers the mud at a higher pressure to the jet nozzle 200, thereby generating a high-speed jet. This allows for more effective mud impact and improves mixing efficiency.

[0047] Reference Figure 1According to the present invention, a hydraulic jet mud mixer 10 has multiple filter holes 311 on the outer peripheral wall of the riser section 310 near its upper end.

[0048] Understandably, filter orifice 311 can effectively block larger solid particles from entering riser section 310 and suction pipeline section 320, preventing these particles from clogging the pipeline or damaging the mud pump 400 during transportation. By filtering larger particles, filter orifice 311 can protect key components such as mud pump 400 and jet nozzle 200 from wear and clogging, extending the service life of the equipment.

[0049] Reference Figure 1 According to the present invention, a hydraulic jet mud mixer 10 is provided, which also includes a second valve 600, which is disposed between the riser section 310 and the suction pipe section 320.

[0050] Understandably, the second valve 600 is installed at the connection between the riser section 310 and the suction pipeline section 320 to control the flow of slurry between these two components. When the valve is closed, the passage between the riser section 310 and the suction pipeline section 320 is blocked, preventing slurry from entering the suction pipeline section 320 from the riser section 310, and consequently, from entering the subsequent slurry circulation loop 300. When the valve is open, the passage is unobstructed, allowing slurry to flow smoothly from the riser section 310 into the suction pipeline section 320, continuing to participate in the slurry circulation and mixing process. This provides flexibility and controllability for the operation of the slurry mixer.

[0051] Reference Figure 1 According to the present invention, a hydraulic jet mud mixer 10 is provided, wherein the mud tank 100 is arranged in the shape of a cylinder with an open upper end 120 and a closed lower end.

[0052] Understandably, the upper opening 120 of the mud tank 100 provides a direct channel for mud injection. In practical applications, whether the mud is transported to the mixer from external equipment or added to the tank after on-site mixing, the upper opening 120 ensures that the mud enters the tank smoothly and quickly. Furthermore, if auxiliary materials (such as additives or chemicals) need to be added during mixing to improve mud properties, the upper opening 120 also facilitates the operator in accurately and conveniently adding the materials to the tank.

[0053] In other words, the opening 120 at the top of the mud tank 100 improves the working efficiency and ease of operation of the mud mixer. It reduces downtime caused by difficulties in mud injection or material addition, ensures the continuity and stability of the mixing process, and also reduces the labor intensity of operators.

[0054] Reference Figure 1According to the present invention, a hydraulic jet mud mixer 10 also includes a cover plate 700, which is semi-circular and covers one side of the upper opening 120 of the mud tank 100.

[0055] Understandably, the cover plate 700 is semi-circular to prevent the slurry from overflowing during mixing, and it can also be used to temporarily place mud material on it so that it can be poured into the mud tank.

[0056] In some embodiments, a hydraulic jet mud mixer 10 further includes a density sensor, which is disposed in the mixing chamber 110 and is connected to the mud pump 400 via a signal connection.

[0057] Understandably, by connecting the density sensor to the mud pump 400, the operating status of the mud pump 400 can be adjusted reasonably according to the actual density of the mud in the mixing chamber 110. This enables automatic mud mixing, extends the service life of the mud pump 400, and reduces the operating costs of the equipment.

[0058] In some embodiments, there are multiple jet nozzles 200, which are evenly distributed around the bottom of the stirring chamber 110.

[0059] It is understood that this embodiment significantly enhances the mixing effect, improves the uniformity and mixing efficiency of the mud, shortens the mixing time, and improves the reliability of the equipment and its adaptability to different working conditions by uniformly distributing multiple jet nozzles 200 around the bottom of the mixing chamber 110.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
