Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and more specifically, to a two-liquid mixing device and mixing method. Background Technology

[0002] In bedrock karst grouting projects, "two liquids" typically refers to two liquids with complementary properties. A cement-based grout (Liquid A) serves as the main agent, while a chemical solution such as water glass (Liquid B) acts as a setting accelerator. This mixture is then used to fill cracks within the bedrock. During the mixing process, Liquid B is added to Liquid A and stirred. Liquid B tends to concentrate in the upper layer and penetrates downwards more slowly, leading to increased stirring time and lower efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a two-liquid mixing device and mixing method to improve mixing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a two-liquid mixing device, comprising a mixing tank and a main rod, the main rod being rotatable along its own axis, a cylindrical body being fixedly connected to the main rod, the cylindrical body being inserted into the mixing tank, a mounting base being fixedly installed on the cylindrical body, a stirring component being fixedly installed on the outer periphery of the mounting base, a first support ring being installed on the inner wall of the mixing tank, the first support ring being located above the mounting base, the first support ring having a flow channel hole one, a through hole one, and a groove, the groove being connected to the flow channel hole one and the through hole one respectively, the mounting base having a countersunk hole, the countersunk hole being located below the through hole one, the cylindrical body having a flow channel hole two and a main flow channel hole, the flow channel hole two being connected to both the countersunk hole and the main flow channel hole; and further comprising a feeding channel, the feeding channel including a discharge port, the discharge port being located above the countersunk hole.

[0005] The present invention is further configured such that the main rod includes a screw, which is inserted into the cylinder.

[0006] The present invention is further configured such that a first guide surface is provided on the inner circumference of the first ring, and one end of the first guide surface extends to the flow channel hole.

[0007] The invention is further configured such that a second frame ring is installed on the mixing tank, the second frame ring is located above the first frame ring, and the second frame ring is provided with a second guide surface, which is located above the flow channel hole one.

[0008] The present invention is further configured such that the stirring component has an inclined surface, which gradually slopes downward in the radial outward direction along the mixing tank.

[0009] The invention is further configured such that an end cap is installed on the top of the mixing tank, a feeding tray is installed on the end cap, and the feeding tray is provided with a feeding channel.

[0010] The invention is further configured such that a geared motor is mounted on the end cap, and the output end of the geared motor is connected to the main rod.

[0011] The invention is further configured such that the cylinder is equipped with stirring blades, which are located below the stirring component.

[0012] The invention is further configured such that a stirring frame is installed on the cylinder, the stirring frame is a tripod structure, a connecting block is installed at the bottom of the stirring frame, and a stirring rod is installed on the connecting block, the stirring rod being L-shaped.

[0013] The present invention also adopts the following technical solution: a two-liquid mixing method, using a two-liquid mixing device, comprising the following steps:

[0014] ① The first liquid is introduced into the mixing tank;

[0015] ② The rotating agitator pushes the first liquid in the mixing tank to flow into the groove from the flow channel hole 1. The first liquid flows into the sink hole along the through hole 1. At the same time, the second liquid is introduced into the feed channel. The second liquid flows down from the outlet and into the sink hole. The first liquid and the second liquid form a mixture and enter the main flow channel hole.

[0016] ③ The two mixed liquids are transferred to the bottom of the mixing tank;

[0017] ④ Thoroughly stir the mixture at the bottom of the mixing tank.

[0018] In summary, the present invention has the following beneficial effects:

[0019] The upper layer of liquid A is pushed into the groove by stirring, and then enters the sink hole to mix with the added liquid B. After mixing, it is discharged from the main channel hole into the bottom of the mixing tank 1 for further stirring. This helps to reduce the accumulation of liquid B on the upper layer of liquid A and improves the reaction efficiency. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1-4 As shown, this embodiment discloses a two-liquid mixing device, including a mixing tank 1 and a main rod 21, the main rod 21 being rotatable along its own axis. Specifically, as... Figure 1 As shown, the mixing tank 1 includes an end cap 11 located at the upper end. The end cap 11 is detachably installed on the mixing tank 1. A geared motor 2 is installed on the end cap 11. The output end of the geared motor 2 is connected to the main rod 21. The main rod 21 rotates along its own axis under the drive of the geared motor 2.

[0027] like Figure 1 As shown, the main rod 21 is fixedly connected to the cylinder 22, and the cylinder 22 is inserted into the mixing tank 1, as shown. Figure 2 As shown, the cylinder 22 has a through main channel hole 222 in the axial direction. The main rod 21 closes the top of the main channel hole 222. The main rod 21 includes a screw 211. The screw 211 is inserted into the main channel hole 222 and rotates to convey materials downward.

[0028] like Figure 2 As shown, a mounting base 23 is fixedly installed on the cylinder 22. The upper end of the mounting base 23 is provided with a countersunk hole 231. The cylinder 22 is provided with a second flow channel hole 221. The second flow channel hole 221 penetrates the outer wall of the cylinder 22. Multiple second flow channel holes 221 are evenly distributed along the circumference of the cylinder 22. The second flow channel hole 221 is connected to the main flow channel hole 222. The main flow channel hole 222 is connected to the countersunk hole 231.

[0029] A stirring component 24 is fixedly installed on the outer periphery of the mounting base 23. When the cylinder 22 rotates, it drives the mounting base 23 and the stirring component 24 to move and rotate.

[0030] like Figures 1-3As shown, a first support ring 12 is installed on the inner wall of the mixing tank 1. The first support ring 12 is located above the mounting base 23. The first support ring 12 has a flow channel hole 1221, a through hole 1222, and a groove 1223. The groove 1223 communicates with the flow channel hole 1221 and the through hole 1222, respectively. A countersunk hole 231 is located below the through hole 1222. The first support ring 12 includes a support ring body 122, and the groove 1223 is located at the upper end of the support ring body 122. Figure 1 , Figure 4 The stirring component 24 has an inclined surface 241, which gradually slopes downwards in the radial outward direction along the mixing tank 1. This allows the stirring component 24 to push the liquid inside the mixing tank 1 when it rotates, causing the liquid to flow upwards along the inner wall of the mixing tank 1. Figure 3 As shown, the bottom inner circumference of the first ring 12 is provided with a first guide surface 121, one end of which extends to the flow channel hole 1221. Under the guiding action of the first guide surface 121, the liquid flows into the flow channel hole 1221 and enters the countersunk hole 231 along the groove 1223 and the through hole 1222.

[0031] The mixing tank 1 is equipped with a second support ring 13, which is located above the first support ring 12. The second support ring 13 has a second guide surface 132, which is located above the flow channel hole 1221 to block the liquid flowing out of the flow channel hole 1221. The liquid in the mixing tank 1 is liquid A, which has low viscosity and good fluidity. Liquid A is a cement-based slurry. The mixing tank 1 is equipped with an inlet for liquid A to be introduced.

[0032] like Figure 1 , Figure 2 As shown, it also includes a feed channel 31, which includes a discharge port 311 located above the counterbore 231. Specifically, the end cap 11 is equipped with a feed pan 3, which has a feed channel 31 connected to a feed inlet 4. The feed inlet 4 is through which liquid B is introduced. Liquid B is a chemical solution such as water glass used as a coagulant. Liquid B is highly reactive and can control solidification. After mixing with liquid A, liquid B gradually forms a solidified slurry with a certain strength and impermeability. After the mixture of liquid B and liquid A is complete, it is injected into the rock foundation to fill its cracks and improve the strength of the rock foundation. The second ring 13 has a second through hole 131, located above the first through hole 1222 and below the discharge port 311, to allow liquid B to pass through.

[0033] Liquid B and liquid A enter the countersink 231 respectively, mix, and enter the main channel 222. Since liquid B and liquid A form a solidified body locally after mixing, they are easily transferred to the lower cavity of the mixing tank 1 by the screw 211.

[0034] like Figure 1As shown, the cylinder 22 is equipped with stirring blades 25, which are located below the stirring component 24. The cylinder 22 is also equipped with a stirring frame 26, which is a tripod structure. A connecting block 27 is installed at the bottom of the stirring frame 26, and a stirring rod 271, which is L-shaped, is mounted on the connecting block 27. The stirring frame 26 guides the liquid to generate radial and axial flow, while the L-shaped stirring rod 271 covers the mixing blind zone. Through synergistic stirring, dead zones in the mixing are avoided, improving the uniformity and efficiency of the two-liquid mixing and solving the problem of uneven mixing in traditional devices affecting the grouting effect in bedrock karst.

[0035] like Figure 1 As shown, the bottom of the mixing tank 1 is provided with a discharge port 14, which is controlled to open and close by a valve 15.

[0036] A two-liquid mixing method, using the above-mentioned two-liquid mixing apparatus, includes the following steps:

[0037] ①Pour liquid A into mixing tank 1.

[0038] ② The geared motor 2 drives the main rod 21 to rotate, so that the screw 211, the cylinder 22, and the stirring component 24 rotate. The rotation of the stirring component 24 pushes liquid A in the mixing tank 1 from the flow channel hole 1221 into the groove 1223, and then flows down into the sink hole 231 along the through hole 1222. At the same time, liquid B is introduced into the feed channel 31 through the feed interface 4. Liquid B flows down from the discharge port 311 and enters the sink hole 231. Liquid A and liquid B are mixed and enter the main flow channel hole 222.

[0039] ③ The screw 211 rotates to transfer the mixed liquid A and liquid B to the bottom of the mixing tank 1.

[0040] ④ The stirring blade 25, stirring frame 26, and stirring rod 271 thoroughly stir the mixture of liquid A and liquid B at the bottom of the mixing tank 1.

[0041] The upper layer of liquid A is pushed to the groove 1223 by stirring, and then enters the sink hole 231 to mix with the added liquid B. After mixing, it is discharged from the main channel hole 222 into the bottom of the mixing tank 1 for further stirring. This helps to reduce the accumulation of liquid B on the upper layer of liquid A and improves the reaction efficiency.

[0042] Since liquid A and liquid B gradually form a solid body after mixing, the screw 211 is used to push the mixture downwards to avoid blockage of the flow channel and to re-stir it in a timely manner.

[0043] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
