Description

Technical Field

[0001] This utility model relates to the field of epoxy resin mineral fiber composite concrete production technology, specifically to an efficient mixing device for epoxy resin mineral fiber composite concrete. Background Technology

[0002] Epoxy resin-mineral fiber composite concrete is mainly composed of epoxy resin, mineral fibers (such as glass fiber or carbon fiber), and other additives (such as curing agents, plasticizers, diluents, etc.). By mixing, molding, and curing these materials, a high-performance composite material is formed. Therefore, it is necessary to use a mixing device to uniformly stir the various raw materials.

[0003] A search revealed that the announcement number is CN219054915U, entitled "A Mixing Device for Composite Material Production," which includes a mixing tank and support legs fixed around the outside of the mixing tank. Research and analysis revealed that although this invention allows for convenient replacement of the stirring paddle and brush rod, and facilitates quick cleaning of the device's interior after mixing, it still has the following drawbacks to some extent.

[0004] For example, the mixing device mentioned above lacks bipolar shear dispersion function, has a relatively simple mixing component structure, and can only mix the raw materials by rotating the mixing rod alone. It cannot achieve uniform mixing by using planetary mixing arms to achieve both revolution and rotation. At the same time, it cannot shear the resin agglomerates and mineral fiber bundles in the raw materials during the mixing process, resulting in insufficient and incomplete mixing. Furthermore, it cannot control the mixing temperature of the raw materials, and cannot improve the fluidity between the raw materials, thus leading to poor mixing efficiency between the raw materials. In order to solve the above technical problems, we have designed an epoxy resin mineral fiber composite concrete high-efficiency mixing device. Utility Model Content

[0005] The purpose of this invention is to provide an efficient mixing device for epoxy resin-mineral fiber composite concrete, which has bipolar mixing, shearing and dispersion functions, effectively improving resin dispersion, making the raw materials more uniform and thorough, controlling the mixing temperature, improving the fluidity between raw materials, avoiding premature resin curing, and having higher mixing efficiency. It solves the problems of relatively simple mixing and stirring methods, which cannot improve resin dispersion, are not uniform and thorough enough, cannot control the mixing temperature, reduce the fluidity between raw materials, and reduce mixing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency mixing device for epoxy resin mineral fiber composite concrete, comprising a mixing tank, a top cover bolted to the top of the mixing tank, a stirring shaft mounted through a sealed bearing on the top of the top cover, a driven gear fixedly sleeved on the top surface of the stirring shaft, the bottom of the stirring shaft extending to the bottom of the mixing tank, rotary joints mounted on both the top and bottom of the stirring shaft, a shearing mechanism welded to the outside of the stirring shaft, the shearing mechanism comprising a fixed horizontal plate, a stirring sleeve welded between the upper and lower fixed horizontal plates, a stator shearing plate welded to the inner cavity of the stirring sleeve, a rotating rod mounted through a bearing between the upper and lower fixed horizontal plates, a rotor shearing plate welded to the surface of the rotating rod, a turntable welded to the top of the rotating rod, an ultrasonic viscometer fixedly connected through the left side of the top of the top cover, and an electric valve for defoaming agent welded to the right side of the top of the top cover.

[0007] Preferably, a support frame is welded to the rear side of the top of the mixing tank, and a drive motor is bolted to the top of the support frame. The output shaft of the drive motor passes through the support frame and is fixedly fitted with a drive gear.

[0008] Preferably, the two rotary joints are connected to an oil drain pipe and an oil injection pipe on opposite sides, respectively, and a drain valve is welded to the rear side of the bottom of the mixing tank.

[0009] Preferably, the mixing tank has an insulated cavity inside, and pipe joints are welded to the top and bottom of the left side of the mixing tank.

[0010] Preferably, a liquid injection pipe is welded to the front side of the top of the top cover, and a through opening is provided on the surface of the stirring sleeve.

[0011] Preferably, a central processing unit is bolted to the left side of the top of the cover, the output of the central processing unit is electrically connected to the defoamer electric valve, and the output of the ultrasonic viscometer is electrically connected to the central processing unit.

[0012] Preferably, the surface of the stirring shaft is movably connected to the bottom of the mixing tank via a sealed bearing, and connecting flanges are welded to both the top and bottom of the stirring shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The drive motor drives the stirring shaft to rotate and stir the raw materials. At the same time, the rotor shear plate and stator shear plate rotate on the inner wall of the mixing tank to crush the resin agglomerates and mineral fiber bundles in the raw materials, improve the dispersion of the resin, and make the raw materials more uniform and thorough.

[0015] 2. Heat transfer oil is injected into the stirring shaft through the oil injection pipe to increase the mixing temperature in the mixing tank, and finally discharged through the oil drain pipe. In this way, the heat transfer oil circulates in the stirring shaft, which can effectively improve the fluidity between raw materials and make the mixing of raw materials more efficient.

[0016] 3. When the ultrasonic viscometer detects that the material viscosity is higher than the preset value, the central processing unit controls the defoamer electric valve to open and the defoamer flows into the mixing tank to reduce the material viscosity. When the viscosity is lower than the preset value, the defoamer electric valve is controlled to close and stop the defoamer injection. This can automatically adjust the amount of defoamer added and improve production efficiency.

[0017] 4. The heating liquid flows into the insulated cavity through the bottom pipe joint and flows out from the top pipe joint to heat and insulate the material in the mixing tank, preventing the resin from curing prematurely. Attached Figure Description

[0024] Please see Figures 1-5A high-efficiency mixing device for epoxy resin mineral fiber composite concrete includes a mixing tank 1. A top cover 2 is bolted to the top of the mixing tank 1. A stirring shaft 15 is mounted through a sealed bearing on the top of the top cover 2. The stirring shaft 15 is hollow. A driven gear 9 is fixedly sleeved on the top surface of the stirring shaft 15. The bottom of the stirring shaft 15 extends to the bottom of the mixing tank 1. Rotary joints 4 are installed at both the top and bottom of the stirring shaft 15. The rotary joint 4 consists of a fixed-side flow path, a rotating-side flow path, and seals that seal these flow paths, allowing connected pipelines to... The rotating stirring shaft 15 is welded to the outside of a shearing mechanism 14. The shearing mechanism 14 includes a fixed horizontal plate 18. A stirring sleeve 20 is welded between the upper and lower fixed horizontal plates 18. A stator shearing plate 19 is welded to the inner cavity of the stirring sleeve 20. A rotating rod 24 is installed through the upper and lower fixed horizontal plates 18 via a bearing. A rotor shearing plate 21 is welded to the surface of the rotating rod 24. A turntable 17 is welded to the top of the rotating rod 24. An ultrasonic viscometer 10 is fixedly connected through the left side of the top of the top cover 2. An antifoaming agent electric valve 7 is welded to the right side of the top of the top cover 2.

[0025] Please see Figure 5 A support frame 6 is welded to the rear side of the top of the mixing tank 1. A drive motor 16 is bolted to the top of the support frame 6. The output shaft of the drive motor 16 passes through the support frame 6 and is fixedly fitted with a drive gear 22. The drive gear 22 is meshed with the driven gear 9.

[0026] Please see Figure 2 The upper and lower rotary joints 4 are connected to the oil drain pipe 5 and the oil injection pipe 8 on opposite sides respectively. The bottom rear side of the mixing tank 1 is welded with a drain valve 13. By setting the drain valve 13, the mixed material in the mixing tank 1 can be easily discharged.

[0027] Please see Figure 2 The mixing tank 1 has an insulated cavity 11 inside. The top and bottom of the left side of the mixing tank 1 are welded with pipe joints 12. By setting the pipe joints 12, it can be connected to the temperature control system pipeline. The heating liquid flows into the insulated cavity 11 through the bottom pipe joint 12 and then flows out from the top pipe joint 12 to heat and keep the material in the mixing tank 1 warm, so as to prevent the resin from curing prematurely.

[0028] Please see Figure 1 and Figure 4 The top of the top cover 2 is welded to the front side of the liquid injection pipe 3. The surface of the stirring sleeve 20 is provided with a through opening. By setting the through opening, the material can flow into the stirring sleeve 20 for shearing.

[0029] Please see Figure 5The top left side of the top cover 2 is connected to the central processing unit 23 by bolts. The output end of the central processing unit 23 is electrically connected to the defoamer electric valve 7, and the output end of the ultrasonic viscometer 10 is electrically connected to the central processing unit 23.

[0030] Please see Figure 2 and Figure 3 The surface of the stirring shaft 15 is movably connected to the bottom of the mixing tank 1 through a sealed bearing. The top and bottom of the stirring shaft 15 are both welded with connecting flanges. By setting the connecting flanges, the stirring shaft 15 can be easily fixedly connected to the rotary joint 4.

[0031] In use, this device is connected to an external power supply and controller. The injection pipe 3 and the defoamer electric valve 7 are respectively connected to the raw material delivery pipeline and the defoamer delivery pipeline. The oil drain pipe 5 and the oil injection pipe 8 are connected to the external heat transfer oil circulation system. Various raw materials are delivered to the mixing tank 1 through the injection pipe 3. Then, the drive motor 16 is controlled to work, which drives the stirring shaft 15 to rotate through the drive gear 22 and the driven gear 9. The rotating stirring shaft 15 drives the surrounding shearing mechanism 14 to rotate and stir the raw materials. Since the turntable 17 is in contact with the inner wall of the mixing tank 1, the turntable 17 rotates on its own axis on the inner wall of the mixing tank 1 as the stirring shaft 15 rotates. The rotor shearing plate 21 on the surface of the rotating rod 24 rotates accordingly. The rotating rotor shearing plate 21 works in conjunction with the fixed stator shearing plate 19 to crush the resin agglomerates and mineral fiber bundles in the raw materials, improve the dispersion of the resin, and make the raw materials more uniformly mixed. Thoroughly, during the mixing process, heat transfer oil is injected into the mixing shaft 15 through the oil injection pipe 8. The rotating mixing shaft 15 dissipates heat, increasing the mixing temperature in the mixing tank 1, and finally discharges through the oil drain pipe 5. This circulation of heat transfer oil within the mixing shaft 15 effectively improves the fluidity between raw materials, making the mixing more efficient. An ultrasonic viscometer 10 is installed to detect the viscosity of the material in the mixing tank 1. Due to excessively high viscosity, a large amount of foam will appear. When the viscosity exceeds the preset value, the ultrasonic viscometer 10 transmits a signal to the central processing unit 23. At this time, the central processing unit 23 controls the defoamer electric valve 7 to open, allowing defoamer to flow into the mixing tank 1 to reduce the viscosity of the material. When the viscosity is lower than the preset value, the defoamer electric valve 7 is controlled to close, stopping the injection of defoamer. This automatically adjusts the amount of defoamer added, improving production efficiency.

[0032] In summary, this high-efficiency mixing device for epoxy resin-mineral fiber composite concrete, through the coordinated use of mixing tank 1, rotary joint 4, oil drain pipe 5, defoamer electric valve 7, oil injection pipe 8, ultrasonic viscometer 10, insulation cavity 11, pipe joint 12, shearing mechanism 14 and stirring shaft 15, solves the problems of relatively simple mixing and stirring methods, inability to improve resin dispersion, insufficient and incomplete mixing, inability to control mixing temperature, reduced fluidity between raw materials, and reduced mixing efficiency.
