Description

Technical Field

[0001] This utility model relates to the field of building material mixing technology, and in particular to a high-efficiency dual-pipe epoxy colored sand static mixing pipe. Background Technology

[0002] The high-efficiency dual-pipe epoxy colored sand static mixing pipe plays a crucial role in the epoxy colored sand construction process. It is used for the graded mixing of two-component raw materials to achieve uniform fusion of epoxy resin and curing agent, so as to form a strong bond and consistent color grouting material. The high-efficiency dual-pipe epoxy colored sand static mixing pipe is often used in projects such as tile grouting and building material repair.

[0003] When a graded mixing operation of two-component raw materials is required to achieve uniform fusion of epoxy resin and curing agent, a high-efficiency dual-tube epoxy colored sand static mixing pipe is needed. Existing epoxy colored sand static mixing pipes are mostly single spiral channel structures, which can easily lead to uneven flow of the two-component raw materials, insufficient shear contact, and high material residue on the inner wall of the pipe. This will increase material loss and thus lead to a significant increase in production costs. At the same time, it will directly cause incomplete fusion of the two components, ultimately resulting in reduced mixing uniformity. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency dual-tube epoxy colored sand static mixing tube, which aims to solve the problem of low mixing uniformity in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency dual-pipe epoxy colored sand static mixing pipe, comprising a mixing pipe, wherein multiple support shafts are fixedly connected inside the mixing pipe, a first sealing shell is rotatably connected to the outer surface of the multiple support shafts, a second sealing shell is rotatably connected to the outer surface of the support shafts, multiple spiral springs are fixedly connected to the outer surface of the support shafts, multiple shearing blades are fixedly connected to the outer surfaces of both the first and second sealing shells, flow grooves are formed on the inner walls of the multiple shearing blades, drive grooves are formed on the inner walls of the multiple shearing blades, mixing plates are slidably connected to the inner walls of the multiple drive grooves, drive joints are rotatably connected between adjacent mixing plates, a connecting pipe is fixedly connected to the outer wall of the mixing pipe, and a premixing structure is threadedly connected to the inner wall of the connecting pipe, the premixing structure being used to initially mix the two materials.

[0006] As a further description of the above technical solution: The premixing structure includes an external thread, the inner wall of which is threadedly connected to the inner wall of a connecting pipe. A connecting shell is fixedly connected to the inner wall of the external thread. A premixing cavity is formed on the inner wall of the connecting shell. Multiple conveying pipes are connected to the inner wall of the premixing cavity. A rotating rod is rotatably connected to the inner wall of each conveying pipe. A spiral blade is fixedly connected to the outer surface of the rotating rod. Guide plates are fixedly connected to the inner walls of each of the multiple conveying pipes.

[0007] As a further description of the above technical solution: The outer wall of the mixing pipe is fixedly connected to a fixing block, and the outer walls of the plurality of spiral springs are respectively fixedly connected to the inner walls of the first sealing shell and the second sealing shell.

[0008] As a further description of the above technical solution: The inner wall of the mixing pipe is connected to an injection port, and a sleeve is slidably connected to the outer wall of the injection port.

[0009] As a further description of the above technical solution: The outer surfaces of the multiple conveying pipes are threaded with tightening components, and the inner walls of the tightening components are rotatably connected to a feeding pipe.

[0010] As a further description of the above technical solution: The inner wall of the feeding pipe is connected to an epoxy colored sand pipe, and the outer wall of the epoxy colored sand pipe is slidably connected to a shell.

[0011] As a further description of the above technical solution: A handle is fixedly connected to the bottom of the outer shell, and the inner wall of the outer shell is slidably connected to the outer surface of the feed tube.

[0012] As a further description of the above technical solution: Multiple push rods are slidably connected to the inner wall of the housing, and limit blocks are fixedly connected to the outer surfaces of the multiple push rods.

[0013] This utility model has the following beneficial effects: 1. In this utility model, during operation, multiple support shafts fixed inside the mixing pipe provide stable support for the mixing structure. The first and second sealing shells outside each support shaft rotate around the shaft under the pressure of the material, and generate elastic oscillation with the spiral spring, automatically adapting to colored sand of different viscosities. Multiple shearing blades are fixed outside each sealing shell. When rotating synchronously with the shell, the flow grooves on the inner wall of the blades realize material diversion and prevent blockage. The rotation of the shearing blades drives the displacement of the drive groove, and the mixing blades in the extrusion groove form sharp corners, shearing the material in multiple rounds. Adjacent mixing blades achieve multi-angle oscillation through the linkage of the drive joint, further agitating the material. Driven by the pressure of the material itself, the mixing uniformity is improved, ensuring shearing strength and adapting to various working conditions, achieving efficient and uniform mixing.

[0014] 2. In this utility model, during use, the external thread and the inner wall thread of the connecting pipe are tightly screwed together to achieve stable installation and prevent material leakage. The connecting shell forms a closed space, and the internal premixing chamber creates conditions for preliminary mixing. The conveying pipe connected to the inner wall of the premixing chamber provides the installation foundation for the rotating rod and fixed spiral blades inside. The spiral blades can disperse the single-component materials and avoid particle agglomeration. At the same time, the inclined guide plate fixed to the inner wall of each conveying pipe accurately guides the two components of materials to be injected into the premixing chamber at a specific angle, forming a high-speed collision and full fusion, improving the premixing uniformity, reducing the fine shearing pressure of the subsequent mixing pipeline, and improving the overall mixing efficiency.

The outer surface of each support shaft 3 is rotatably connected to the first sealing shell 4 and the second sealing shell 5, respectively. The spiral spring 6 can automatically adapt to the flow characteristics of colored sand with different viscosities through elastic swing. Multiple shearing blades 7 are fixed on the outer surface of each sealing shell. Multiple flow grooves 8 are opened on the inner wall of the shearing blades 7 to allow some material to flow through. At the same time, multiple mixing plates 10 slidably connected in the drive groove 9 on the inner wall continuously squeeze the mixing plates 10 when the shearing blades 7 are squeezed by the material and rotate. This causes the drive groove 9 to displace and squeeze the mixing plates 10, forming sharp angles between the left and right mixing plates 10, and performing multiple rounds of shearing and dividing of the material. Adjacent mixing plates 10 are linked through the drive joint 11. Through the joint transmission, the mixing plates 10 swing at multiple angles, further agitating the material. The connecting pipe 12 on the outer wall of the mixing pipe 1 is fixed to the premixing structure 2 through threads. The two components of material first complete the initial fusion through this structure before entering the mixing pipe 1, and finally achieve uniform mixing.

The connecting shell 202 fixed to its inner wall forms a closed load-bearing structure. The premixing chamber 203 opened inside provides a space for preliminary mixing. The inner wall of the premixing chamber 203 is connected to multiple conveying pipes 204, which correspond to the conveying channels of the two components of materials respectively. The rotating rod 205 on the inner wall of each conveying pipe 204 has a spiral blade 206 fixed on its outer surface. When the material flows, it pre-disperses the single component material. At the same time, the inclined guide plate 207 fixed to the inner wall of each conveying pipe 204 guides the material into the premixing chamber 203, so that the two components of materials form an opposing collision in the chamber, completing the preliminary fusion and laying the foundation for subsequent fine mixing.

[0020] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A fixing block 13 is fixedly connected to the outer wall of the mixing pipe 1. The outer walls of multiple spiral springs 6 are fixedly connected to the inner walls of the first sealing shell 4 and the second sealing shell 5 respectively. The outer surfaces of multiple conveying pipes 204 are threadedly connected to tightening parts 16. The inner wall of the tightening parts 16 is rotatably connected to a feeding pipe 17. The inner wall of the mixing pipe 1 is connected to an injection port 14. The outer wall of the injection port 14 is slidably connected to a sleeve 15.

The outer walls of multiple spiral springs 6 are respectively fixed to the inner walls of the first sealing shell 4 and the second sealing shell 5, providing elastic restoring force for the rotation of the sealing shell and ensuring the cyclic operation of the mixing structure. The outer surfaces of multiple conveying pipes 204 are threaded with tightening parts 16, which fix the feed pipe 17 by tightening and at the same time seal the connection to prevent leakage. The feed pipe 17 can rotate around the inner wall of the tightening part 16 for convenient and quick connection and fixation. The injection port 14 connected to the inner wall of the mixing pipe 1 provides a discharge channel for the mixed material. The sleeve 15 slidably connected to its outer wall can be adjusted back and forth to accurately control the discharge range and adapt to the filling needs of different widths.

[0021] Please see the appendix Figure 1 and attached Figure 2 The inner wall of the feed pipe 17 is connected to the epoxy colored sand pipe 18, the outer wall of the epoxy colored sand pipe 18 is slidably connected to the outer shell 19, the inner wall of the outer shell 19 is slidably connected to multiple push rods 21, the outer surface of the multiple push rods 21 is fixedly connected to the limit block 22, the bottom of the outer shell 19 is fixedly connected to the handle 20, and the inner wall of the outer shell 19 is slidably connected to the outer surface of the feed pipe 17.

[0022] Working principle: During operation, multiple support shafts 3 are fixed inside the mixing pipe 1 to provide stable support for the overall mixing structure. The first sealing shell 4 and the second sealing shell 5 outside each support shaft 3 rotate around the shaft under the pressure of material flow. With the help of the spiral spring 6, they generate elastic swing, automatically adapting to colored sand of different viscosities. The shearing blades 7 fixed outside each sealing shell rotate synchronously with the sealing shell. The flow groove 8 on the inner wall of the blade allows some material to flow away to avoid blockage. At the same time, when the shearing blades 7 are squeezed and rotated by the material, the drive groove 9 is displaced. The mixing blades 10 in the squeeze groove form sharp angles on the left and right sides to shear and divide the material. Adjacent mixing blades 10 are linked through the drive joint 11 to realize multi-angle swing, further agitating the material. Driven by the pressure of the material itself, it can not only ensure shear strength, but also adapt to materials of different viscosities, achieving efficient and uniform mixing. In use, the external thread 201 is tightly screwed into the inner thread of the connecting pipe 12 to achieve a stable installation and prevent material leakage. The connecting shell 202 forms a closed space, and the premixing chamber 203 inside creates conditions for preliminary mixing. Multiple conveying pipes 204 connected to the inner wall of the premixing chamber 203 form independent conveying channels. The spiral blades 206 fixed on the outer surface of the rotating rod 205 inside the conveying pipe 204 disperse the single-component materials to prevent particle agglomeration. At the same time, the guide plate 207 fixed on the inner wall of each conveying pipe 204 accurately guides the two-component materials to be injected into the premixing chamber 203 at a specific angle. The different components collide at high speed in the chamber, fully intertwine and blend, and complete the preliminary mixing, laying the foundation for fine shearing in the subsequent mixing pipe 1 and improving the overall premixing uniformity.
