Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices, specifically to a mixing and stirring device used in the preparation of epoxy resin self-leveling. Background Technology

[0002] Epoxy self-leveling flooring, as a high-performance flooring material, is widely used in industrial plants, commercial spaces, and other scenarios due to its excellent wear resistance, corrosion resistance, and high smoothness. During its application, the mixing device is the core equipment that ensures the uniform mixing of epoxy resin, curing agent, filler, and other components, directly affecting the performance and quality of the final coating.

[0003] Currently, epoxy resin self-leveling compound is mostly mixed at room temperature, relying on mechanical stirring blades to achieve material mixing. However, in low-temperature construction scenarios (such as winter or cold regions), the viscosity of epoxy resin and curing agent increases significantly, leading to a decrease in mixing efficiency and problems such as uneven filler dispersion and residual air bubbles. At the same time, low temperatures slow down the cross-linking reaction rate of epoxy resin, and may even lead to incomplete curing, resulting in quality defects such as insufficient coating hardness and reduced adhesion.

[0004] In the prior art, some self-leveling mortar mixing devices with heating functions control the temperature by setting a heating layer (such as electric heating wire or heat transfer oil circulation) on the outer wall of the mixing tank. For example, Chinese patent application No. 202123300404.7 discloses a mixing device for preparing lightweight thermal insulation gypsum self-leveling mortar, which has an electric heating jacket attached to the outside of the tank. The electric heating jacket heats the tank to ensure the temperature of the material inside the tank, which is convenient for winter construction on site. However, this method has obvious drawbacks:

[0005] Poor heating uniformity: Heat needs to be transferred to the material indirectly through the barrel wall. The central area heats up slowly, which easily forms a temperature gradient, resulting in local overheating or cold areas, affecting the mixing effect.

[0006] Low energy efficiency: A large amount of heat is lost to the environment, resulting in low heating efficiency and high energy costs;

[0007] Complex structure: The external heating layer increases the size and weight of the equipment, makes maintenance inconvenient, and makes it difficult to meet the mobile needs of the construction site. Utility Model Content

[0019] Figure 2 This is a circuit connection diagram of a mixing and stirring device for preparing epoxy resin self-leveling compound, provided in Embodiment 1 of this utility model. Detailed Implementation

[0020] Example 1:

[0021] The mixing and stirring device for preparing epoxy resin self-leveling compound provided in Embodiment 1 of this utility model, such as Figures 1 to 2 As shown, the device includes a container 1, a motor 2, and a stirring shaft 3. The container 1 includes a stirring chamber 4 and is equipped with a feed pipe 11 and a discharge pipe 12. Both the feed pipe 11 and the discharge pipe 12 are connected to the stirring chamber 4. The housing of the motor 2 is fixed to the container 1. The stirring shaft 3 is fixed to the output shaft of the motor 2. The motor 2 can drive the stirring shaft 3 to rotate along the shaft of the stirring shaft 3. The stirring shaft 3 is located inside the stirring chamber 4. The stirring shaft 3 is a temperature-adjustable stirring shaft 3.

[0022] The mixing and stirring device for preparing epoxy resin self-leveling compound provided in Embodiment 1 of this utility model, when used in low-temperature construction scenarios (such as winter or cold regions), involves feeding the material into the feed pipe 11, closing the inlet of the feed pipe 11, and then using the motor 2 to drive the stirring shaft 3 to rotate and stir the material. After the material is mixed, the motor 2 is turned off, the stirring shaft 3 stops rotating, and the outlet pipe 12 is opened to discharge the material. To avoid the problem of uneven filler dispersion and residual air bubbles caused by a significant increase in the viscosity of epoxy resin and curing agent in low-temperature environments, this embodiment... The device heats up the stirring shaft 3 and then transfers the heat to the material to be stirred inside the container 1. Compared with the heating method of setting heating elements on the outside of the container 1 in the prior art, the device provided in this embodiment does not need to transfer heat to the material indirectly through the barrel wall. The central area heats up faster than the prior art, thereby avoiding the formation of temperature gradients that could lead to local overheating or cold spots. Since the stirring shaft 3 is located inside the stirring cavity 4, the temperature of the stirring shaft 3 is directly transferred to the material, which can prevent a large amount of heat from being lost to the environment. Furthermore, since no external heating layer is needed to increase the size of the equipment, the maintenance and relocation of the stirring device are more convenient.

[0023] The mixing and stirring device for preparing self-leveling epoxy resin provided in Embodiment 1 of this utility model solves the problem of low energy utilization rate of the heating function in the stirring device in the prior art, thereby reducing heating energy consumption and improving heating effect.

[0024] To specifically achieve the heating of the stirring shaft 3, in this embodiment, the stirring shaft 3 includes a shaft body 31 and stirring blades 32; a pipe space 5 is provided inside the shaft body 31; the motor 2 is fixed outside the stirring cavity 4; the shaft body 31 is fixed on the output shaft of the motor 2; the shaft body 31 extends vertically; the shaft body 31 is rotatably fixed on the container 1; the upper end of the shaft body 31 extends out of the stirring cavity 4 from the upper side of the stirring cavity 4; the connection between the shaft body 31 and the container 1 is sealed; a water inlet 311 is provided on the part of the shaft body 31 outside the stirring cavity 4; a water outlet 312 is provided at the bottom of the shaft body 31; the water inlet 311 and the water outlet 312 are connected to the pipe space 5; an electromagnetic valve 6 is provided at the water outlet 312; the water inlet of the electromagnetic valve 6 is connected to the water outlet 312; the stirring blades 32 are provided inside the stirring cavity 4; the stirring blades 32 are fixed to the side wall of the shaft body 31. When it is necessary to heat up the mixing shaft 3, hot water is injected into the pipe space 5 from the water inlet 311 toward the shaft body 31 after the material is placed in the mixing chamber 4. The hot water flows through the pipe space of the shaft body 31, conducting heat to the shaft body and causing it to heat up. After the mixing is completed and the material is discharged from the mixing chamber 4, the cooled water in the shaft body 31 can be opened by remote control of the solenoid valve 6 to allow water to flow into the mixing chamber 4 and finally be discharged from the discharge pipe 12. For some epoxy resin self-leveling materials that require the addition of water as a raw material, the discharge pipe 12 can be closed after the previous mixing is completed and the material is fully discharged from the discharge pipe 12. Then, the water with residual heat in the shaft body 31 is injected into the mixing chamber 4 as a raw material, thereby avoiding the waste of water resources and heat energy.

[0025] To prevent the material in the mixing chamber 4 from flowing back into the shaft body 31 during the mixing process and clogging the pipe space 5, in this embodiment, a filter device 7 is provided between the water outlet 312 and the solenoid valve 6; the filter device 7 is a metal filter screen or a porous ceramic filter element.

[0026] To fully utilize the thermal energy of the hot water, as a preferred embodiment, a temperature sensor 8 is installed on the inner wall of the shaft body 31 of the stirring shaft, and a control module 9 is installed on the outer side of the container 1; the temperature sensor 8 and the control module 9 are electrically connected. The temperature sensor 8 can monitor the temperature of the hot water in the pipe space 5 and feed it back to the control module 9, allowing staff to determine whether the hot water needs to be replaced based on the temperature.

[0027] As a preferred embodiment, in this case, the outer wall of container 1 is provided with an insulation layer; the insulation layer is made of polyurethane foam material. The insulation layer can reduce heat loss from the side wall of container 1, thereby avoiding waste of thermal energy resources.

[0028] In summary, this utility model provides a mixing and stirring device for the preparation of epoxy resin self-leveling compound, relating to the technical field of stirring devices. It includes a container, a motor, and a stirring shaft. The container includes a stirring chamber; the container is provided with an inlet pipe and an outlet pipe; both the inlet pipe and the outlet pipe are connected to the stirring chamber; the housing of the motor is fixed to the container; the stirring shaft is fixed to the motor output shaft; the motor can drive the stirring shaft to rotate along its axis; the stirring shaft is disposed inside the stirring chamber; and the stirring shaft is a temperature-adjustable stirring shaft.
