Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, specifically to a stirring device for high-viscosity materials with a heating structure. Background Technology

[0002] In the field of high-viscosity material handling, mixing devices are crucial equipment, widely used in numerous industries such as chemical, food, pharmaceutical, and coatings. High-viscosity materials are characterized by high viscosity and poor flowability, making their mixing and processing more challenging than that of ordinary materials. Heating plays a key role in improving the mixing effect and quality of high-viscosity materials. Traditional mixing devices mostly lack effective water level monitoring methods. Operators typically rely on experience to judge the water level or need to frequently open the device for observation. This not only increases the complexity and labor intensity of operation but also may lead to material contamination from external sources. Furthermore, the inability to monitor water level changes in real time prevents timely intervention when water levels are abnormal, potentially causing safety accidents or affecting mixing and heating effects.

[0003] The existing device lacks a component for observing the water level. When the water level is too low, the device is prone to dry burning, which affects its use. Therefore, we need to propose a high-viscosity material stirring device with a heating structure. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A stirring device for high-viscosity materials with a heating structure, comprising:

[0027] A stirring drum 1 is provided with a drum cover 2 at its upper end. An electric heating shell 4 is fixedly connected inside the stirring drum 1. Multiple connecting blocks 5 are fixedly connected inside the electric heating shell 4 in a ring. A heat-conducting inner cylinder 6 is in contact with the side wall of the multiple connecting blocks 5. The heat-conducting inner cylinder 6 is in contact with the drum cover 2. A water level observation component 10 for observing the water level is provided on the side wall of the stirring drum 1.

[0028] A liquid reflux assembly is provided on the stirring tank 1.

[0029] For example, the stirring drum 1, as the main structure of the entire device, serves as heat insulation. The drum cover 2 not only seals the material to prevent splashing during stirring but also provides support for the installation of other components. The electric heating shell 4 is the core component of the heating structure, converting electrical energy into heat energy to provide power for heating the material. Multiple connecting blocks 5 are evenly distributed, providing stable support and heat transfer. The heat-conducting inner cylinder 6 is made of a material with high thermal conductivity, enabling it to quickly and evenly transfer the heat generated by the electric heating shell 4 to the material inside. The heat-conducting inner cylinder 6 is in close contact with the drum cover 2, ensuring that heat is not lost from the contact point and improving heating efficiency. In addition, the stirring drum 1... A water level observation component 10 is installed on the side wall to observe the water level. This component allows for real-time monitoring of the water level inside the mixing drum, preventing abnormal water levels from affecting the mixing and heating effects of the materials. A liquid reflux component is installed on the mixing drum 1. This component plays a crucial role in achieving the circulation and uniform heating of the materials. In actual mixing, high-viscosity materials may experience uneven mixing due to their high viscosity. The liquid reflux component enables the materials to circulate within the device, thereby improving the uniformity of mixing. At the same time, through heat exchange during the reflux process, the heating effect of the materials can be further enhanced, ensuring a consistent material temperature throughout the mixing drum.

[0030] The water level observation assembly 10 includes a transparent tube 101, a warning line 102, a high-temperature resistant float 103, and a breathable plate 104;

[0031] A transparent tube 101 is fixedly connected to the side wall of the mixing drum 1. A warning line 102 is fixedly connected to the outside of the transparent tube 101. A high-temperature resistant float 103 is slidably connected inside the transparent tube 101. A breathable plate 104 is fixedly connected to the upper end of the transparent tube 101.

[0032] For example, the transparent tube 101 is made of a high-strength, high-temperature resistant transparent material, such as plexiglass, so that the operator can clearly observe the changes in the internal water level. The warning line 102 indicates the lower limit of the normal water level range. When the water level approaches or exceeds the warning line, the operator can take corresponding measures (add water) in time to ensure the normal operation of the stirring process. The high-temperature resistant float 103 is made of a lightweight, high-temperature resistant and buoyant material, such as foam plastic with a high-temperature resistant coating. It can float up and down in the transparent tube 101 with the changes in water level, intuitively reflecting the water level height in the stirring drum. The vent plate 104 is provided with multiple tiny vent holes, which can not only ensure that the air pressure in the transparent tube 101 is balanced with the external atmospheric pressure, so that the high-temperature resistant float 103 can float normally, but also prevent external impurities from entering the transparent tube 101 and affecting the observation effect.

[0033] The liquid reflux assembly includes an inlet pipe 3, an outlet pipe 11, an internal gear pump 12, a discharge pipe 13, and a reflux pipe 14;

[0034] The inner part of the cylinder cover 2 is fixedly connected to the feed pipe 3. The inner parts of the mixing cylinder 1 and the heat-conducting inner cylinder 6 are both fixedly connected to the discharge pipe 11. The lower end of the mixing cylinder 1 is fixedly connected to the internal gear pump 12. The feed port of the internal gear pump 12 is fixedly connected to the discharge pipe 11. The discharge port of the internal gear pump 12 is fixedly connected to the discharge pipe 13. The outer side of the discharge pipe 13 is fixedly connected to the return pipe 14. The return pipe 14 is fixedly connected to the feed pipe 3. The bend of the return pipe 14 is made of flexible material.

[0035] For example, the inside of the cylinder cover 2 is fixedly connected to the feed pipe 3 by a sealing connection. The feed pipe 3 serves as the channel for material to enter the mixing drum. Its inner diameter is reasonably designed according to the flow rate and viscosity of the material to ensure that the material can flow smoothly into the mixing drum. The mixing drum 1 and the heat-conducting inner cylinder 6 are both fixedly connected to the discharge pipe 11. One end of the discharge pipe 11 extends into the mixing drum near the bottom so that the mixed material can be extracted. The other end is connected to subsequent equipment. The lower end of the mixing drum 1 is fixedly connected to the internal gear pump 12 by bolts or other means. The internal gear pump 12 has the advantages of compact structure, uniform flow, and low noise, and is suitable for conveying high-viscosity materials. The feed of the internal gear pump 12... The outlet and discharge pipe 11 are fixedly connected by means of flange connection or other means to ensure tight connection and prevent material leakage. The discharge port of the internal gear pump 12 is fixedly connected to the discharge pipe 13. The discharge pipe 13 transports the extracted material to the designated position. The outside of the discharge pipe 13 is fixedly connected to the return pipe 14, which is fixedly connected to the feed pipe 3. In this way, a part of the material can return to the mixing drum through the return pipe 14 to form a circulating mixing. The bend of the return pipe 14 is made of flexible material, such as rubber hose. The flexible material has good bending performance and corrosion resistance, which can adapt to the use requirements of the return pipe 14 at different installation angles, while reducing the flow resistance of the material at the bend and facilitating the loading and unloading of the drum cover 2.

[0036] The inside of the cylinder cover 2 is rotatably connected to a stirring frame 7. Multiple symmetrically distributed stirring blades are fixedly connected to the side wall of the stirring frame 7. The upper end of the stirring frame 7 is fixedly connected to the output shaft of a motor 8. The motor 8 is fixedly connected to the cylinder cover 2.

[0037] For example, the stirring frame 7 is one of the core components of the stirring device. Its material is usually a high-strength, corrosion-resistant metal, such as stainless steel, to ensure that it will not deform or be damaged during long-term stirring. Multiple symmetrically distributed stirring blades are fixedly connected to the side wall of the stirring frame 7. The shape and number of stirring blades are designed according to the characteristics of the material and the stirring requirements. Generally, they are spiral or paddle-shaped, which can generate strong stirring force to fully mix the material in the stirring drum. The upper end of the stirring frame 7 is fixedly connected to the output shaft of the motor 8. The motor 8 serves as the power source for stirring. A model with appropriate power and adjustable speed is selected to meet the needs of different materials and stirring processes. The motor 8 is fixedly connected to the drum cover 2 by bolts or other means to ensure that the motor 8 is stable and reliable during operation.

[0038] An external pipe 9 is fixedly connected inside the cylinder cover 2, and a control valve is installed on the external pipe 9.

[0039] For example, water can be injected into the device through the external pipe 9 to prevent the heating shell 4 from burning dry. At the same time, the control valve on the external pipe 9 can be opened to release the gas inside the device and prevent the gas pressure inside the device from becoming too high.

[0040] Working principle: The highly viscous material to be stirred is slowly injected into the mixing drum 1 through the feed pipe 3. The motor 8, which is fixedly connected to the mixing frame 7, is started. The motor 8 drives the mixing frame 7 to rotate, and the multiple symmetrically distributed mixing blades on the mixing frame 7 rotate accordingly, generating a strong stirring force, so that the highly viscous material begins to be stirred and mixed in the mixing drum 1. At the same time, the power supply of the electric heating shell 4 is turned on. The electric heating shell 4 converts electrical energy into heat energy. The heat-conducting inner cylinder 6 quickly and evenly transfers heat to the highly viscous material inside, so that the material temperature gradually rises.

[0041] During the stirring and heating process, the operator can observe the water level in the stirring drum 1 in real time through the water level observation component 10 on the side wall of the stirring drum 1. The warning line 102 fixedly connected to the outside of the transparent tube 101 indicates the lower limit of the normal water level range. When the water level is close to or exceeds the warning line 102, the operator can add an appropriate amount of water to the stirring drum 1 through the external pipe 9.

[0042] After stirring and heating for a period of time, the internal gear pump 12 fixedly connected to the lower end of the stirring drum 1 is started. The internal gear pump 12 pumps the extracted material through the discharge port to the discharge pipe 13. The return pipe 14 fixedly connected to the outside of the discharge pipe 13 is fixedly connected to the feed pipe 3. A portion of the material returns to the stirring drum 1 through the return pipe 14, forming a circulating stirring.

[0043] During the stirring and heating process, gas will be generated inside the stirring drum 1, causing the gas pressure to rise. At this time, the operator can open the control valve on the external pipe 9 to discharge the gas inside the device, prevent the gas pressure inside the device from being too high, and ensure the safe operation of the device.

[0044] The control method of motor 8 in this application is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail in this application. The device is powered by a built-in power supply or an external power supply.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
