Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and specifically discloses a multi-layer flow-guided chemical additive preheating tank. Background Technology

[0002] Chemical additives, as important components in industrial production, are widely used in plastics, rubber, coatings, and other fields. Their pretreatment process has a crucial impact on the performance of the final product. The preheating process can effectively reduce the viscosity of additives, improve their dispersibility, and ensure the stability of subsequent processes.

[0003] Existing preheating equipment mostly adopts a single-layer heating structure, which cannot perform zoned temperature control, resulting in problems such as inaccurate temperature control and low thermal efficiency. Especially for high-viscosity or heat-sensitive additives, local overheating, coking, or decomposition are prone to occur, affecting product quality and production efficiency. Therefore, a multi-layer flow-guided chemical additive preheating tank is needed to solve this problem. Summary of the Invention

[0004] This invention proposes a multi-layer flow-guided preheating tank for chemical additives. Through a multi-layer flow-guided zone temperature control design combined with a heat transfer oil homogenization system, it achieves precise step-by-step preheating of chemical additives. The copper heat exchange structure, combined with intelligent temperature control, significantly improves heating uniformity and efficiency.

[0005] This utility model is implemented as follows: a multi-layer flow-guiding chemical additive preheating tank includes a tank body, with an inlet and an outlet respectively provided at the upper and lower ends of the tank body. An inner cylinder is provided inside the tank body. Spiral guide vanes are fixedly connected between the outer wall of the inner cylinder and the inner wall of the tank body. The spiral guide vanes are wavy near the outer wall of the inner cylinder. Two heat insulation plates are fixedly connected to the inner wall of the inner cylinder, which divide the inner cavity of the inner cylinder from top to bottom into a low-temperature preheating chamber, a constant-temperature heating chamber, and a high-temperature shaping chamber. The inner walls of the low-temperature preheating chamber, the constant-temperature heating chamber, and the high-temperature shaping chamber are all equipped with independently temperature-controlled electric heating tubes. The interiors of the low-temperature preheating chamber, the constant-temperature heating chamber, and the high-temperature shaping chamber are all filled with heat-conducting oil.

[0006] As a preferred embodiment of the multi-layer flow-guided chemical additive preheating tank of this utility model, temperature sensors are provided on the inner walls of the low-temperature preheating chamber, the constant-temperature heating chamber, and the high-temperature shaping chamber.

[0021] Please see Figure 1-3 A multi-layer flow-guided preheating tank for chemical additives includes a tank body 1. The tank body 1 has an inlet 2 and an outlet 3 at its upper and lower ends, respectively. An inner cylinder 4 is installed inside the tank body 1. Spiral guide vanes 5 are fixedly connected between the outer wall of the inner cylinder 4 and the inner wall of the tank body 1. The spiral guide vanes 5 are wavy near the outer wall of the inner cylinder 4. Two vertically distributed heat insulation plates 6 are fixedly connected to the inner wall of the inner cylinder 4. The two heat insulation plates 6 divide the inner cavity of the inner cylinder 4 from top to bottom into a low-temperature preheating chamber 601, a constant-temperature heating chamber 602, and a high-temperature shaping chamber 603. Each of the three chambers has an independently temperature-controlled electric heating tube 7 installed on its inner wall. The interiors of the low-temperature preheating chamber 601, the constant-temperature heating chamber 602, and the high-temperature shaping chamber 603 are filled with heat-conducting oil.

[0022] In this embodiment: the material falls slowly layer by layer under the guidance of the spiral guide vanes 5, prolonging the heat exchange time. The inner cylinder 4 is divided into a low-temperature preheating chamber 601, a constant-temperature heating chamber 602, and a high-temperature shaping chamber 603 by two heat insulation plates 6 (the heat insulation plates 6 are made of densified ceramic fiber boards with a polytetrafluoroethylene oil-resistant coating on the surface). The temperature of the low-temperature preheating chamber 601 is set at 50-80℃. The electric heating tube 7 heats the heat transfer oil, initially reducing the viscosity of the material and evaporating a small amount of moisture. The constant-temperature chamber... The temperature of the heating chamber 602 is controlled at 80-120℃ to fully activate the additives and avoid local overheating. The temperature of the high-temperature setting chamber 603 is raised to 120-160℃ to ensure that the material reaches the final process requirements for fluidity. After being fully heated, the material is discharged from the bottom outlet 3. This utility model achieves efficient and uniform preheating of chemical additives through a multi-layer flow guiding structure and the design of independently temperature-controlled low-temperature preheating chamber 601, constant-temperature heating chamber 602 and high-temperature setting chamber 603, combined with a heat transfer oil homogenization system.

Valves are provided on the outer walls of the plurality of oil inlet and outlet pipes 9.

[0026] In this embodiment: by opening the valve on the outer wall of the inlet / outlet oil pipe 9, it is convenient to replace the heat transfer oil.

[0027] As a technical optimization of this utility model, the outer wall of the inner cylinder 4 is fixedly connected with spiral heat exchange fins 10.

[0028] In this embodiment, the heat exchange efficiency is improved by fixing the spiral heat exchange fins 10 to the outer wall of the inner cylinder 4.

[0029] As a technical optimization of this utility model, the outer wall of the tank 1 is provided with a heat insulation layer.

[0030] In this embodiment: by setting an insulation layer on the outer wall of the tank 1, heat loss is reduced, thermal efficiency is improved and temperature stability is maintained, thereby reducing energy consumption and optimizing the preheating effect.

[0031] As a technical optimization of this utility model, the inner cylinder 4 and the spiral heat exchange fins 10 are made of copper.

[0032] In this embodiment, the use of a copper inner cylinder 4 and spiral heat exchange fins 10 can significantly improve thermal conductivity, accelerate heat exchange speed, enhance corrosion resistance, and extend the service life of the equipment.

[0033] As a technical optimization of this utility model, a controller is provided on the outer wall of the tank 1, and multiple electric heating tubes 7 and multiple temperature sensors 8 are electrically connected to the controller.

[0034] In this embodiment, the controller intelligently links the electric heating element 7 and the temperature sensor 8 to achieve precise temperature control and automatic adjustment of heating power.

[0035] The working principle and usage process of this utility model: Under the guidance of the spiral guide vanes 5, the material falls slowly layer by layer, extending the heat exchange time. The inner cylinder 4 is divided into a low-temperature preheating chamber 601, a constant-temperature heating chamber 602, and a high-temperature shaping chamber 603 by two heat insulation plates 6. The temperature of the low-temperature preheating chamber 601 is set at 50-80℃. The electric heating tube 7 heats the heat transfer oil, initially reducing the viscosity of the material and evaporating a small amount of water. The temperature of the constant-temperature heating chamber 602 is controlled at 80-120℃ to fully activate the additives and avoid local overheating. The temperature of the high-temperature shaping chamber 603 is raised to 120-160℃ to ensure that the material reaches the final process requirements for fluidity. After being fully heated, the material is discharged from the bottom outlet 3. This utility model, through the multi-layer guide structure and the design of independently temperature-controlled low-temperature preheating chamber 601, constant-temperature heating chamber 602, and high-temperature shaping chamber 603, combined with the heat transfer oil homogenization system, achieves efficient and uniform preheating of chemical additives.
