Description

Technical Field

[0001] This utility model relates to the field of foam production technology, and in particular to a jacketed constant temperature preheating storage tank for foam raw materials. Background Technology

[0002] In the field of foam material production, the preheating treatment of foam raw materials plays a crucial role in product quality and production efficiency. Jacketed constant temperature preheating tanks can provide a stable and suitable preheating environment for foam raw materials through precise temperature control. This not only helps improve the flowability of foam raw materials, making them easier to process in subsequent foaming and molding processes, and reducing problems such as inconsistent bubble size and density caused by uneven raw material temperature, thus improving the quality and stability of foam products, but also accelerates the production process, shortens the production cycle, reduces energy consumption, and improves enterprise production efficiency through constant temperature preheating. This is of great significance for promoting the development of foam material production towards refinement and high efficiency.

[0003] In existing foam raw material preheating tanks, heating is often achieved by simply wrapping electric heating wires around the outside of the tank or by installing heating tubes inside the tank. The working principle is to rely on the heat generated by the electric heating element to directly heat the tank or the raw material inside through heat conduction or heat convection.

[0004] However, existing foam raw material preheating tanks have significant drawbacks. Traditional heating methods struggle to achieve uniform and stable temperature control. Heat is concentrated in the contact area between the electric heating wire or heating tube and the raw material, while the temperature is lower in areas far from the heating element, resulting in uneven heating of the raw material and affecting the quality of foam products. Moreover, due to the lack of efficient heat exchange circulation, the reheating rate is slow when the raw material temperature drops, making it difficult to quickly return to the preset temperature. This makes it difficult to meet the requirements for constant temperature preheating of foam raw materials in continuous and large-scale production, resulting in low production efficiency. Therefore, a jacketed constant temperature preheating tank for foam raw materials is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a jacketed constant temperature preheating tank for foam raw materials, which aims to improve the problem in the prior art that it is difficult to achieve uniform and stable temperature control and that the reheating speed is slow when the raw material temperature drops.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A jacketed constant temperature preheating storage tank for foam raw materials includes a tank body, a jacket layer fixedly connected to the outer wall of the tank body, a control panel provided on the outer wall of the jacket layer, a spiral tube provided inside the jacket layer, the spiral tube being sleeved on the outer wall of the tank body, an input pipe fixedly connected to one end of the spiral tube, an output pipe fixedly connected to the other end of the spiral tube, a fixing ring fixedly connected to the outer wall of the jacket layer, a heating box fixedly connected to the outer wall of the fixing ring, a heating component provided inside the heating box, and a mixing component provided inside the tank body; The heating assembly includes a heating rod that passes through the interior of the heating chamber.

[0008] As a further description of the above technical solution: A motor is fixedly connected to the top of the tank, and the output end of the motor is connected to the top of the rotating rod.

[0009] As a further description of the above technical solution: A connecting frame is fixedly connected to the outer wall of the rotating rod, and a support rod is fixedly connected to the side wall of the connecting frame.

[0010] As a further description of the above technical solution: One end of the support rod is fixedly connected to a connecting rod, and a scraper is fixedly connected to one side of the connecting rod. The outer wall of the scraper is in contact with the inner wall of the tank.

[0011] As a further description of the above technical solution: A support frame is fixedly connected inside the tank, and a U-shaped tube is fixedly connected to the bottom of the support frame. Multiple nozzles are provided at the bottom of the U-shaped tube.

[0012] As a further description of the above technical solution: A water injection pipe is fixedly connected to the outer wall of the U-shaped tube, and the water injection pipe passes through the tank body and the jacket layer.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the target temperature is set through the control panel, the heating rod heats the medium in the heating box, and the circulating pump transports the high-temperature medium to the spiral tube through the heat extraction pipe and the heat delivery pipe. The medium flows along the spiral tube and exchanges heat with the tank. The structure of low-temperature medium recirculation achieves the effect of constant temperature and uniform preheating of foam raw materials, solves the problem of difficulty in achieving uniform and stable temperature control, and slow reheating speed when the raw material temperature drops, thereby improving the practicality of the preheating tank.

[0015] 2. In this utility model, the rotating rod and stirring blade are driven by the starting motor to stir the raw materials. At the same time, the rotating rod drives the connecting frame and support rod, causing the connecting rod and scraper to rotate and scrape off the raw materials on the inner wall of the tank.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a jacketed constant-temperature preheating storage tank for foam raw materials, comprising a tank body 1, which serves as the core storage unit. The tank body 1 is made of high-strength stainless steel, and its inner wall is mirror-polished, which not only effectively prevents the foam raw materials from adhering but also avoids chemical reactions between the raw materials and the metal, ensuring stable raw material quality. A jacket layer 2 is fixedly connected to the outer wall of the tank body 1, which is welded from double-layer stainless steel plates. The jacket layer forms a sealed space, providing an installation location for the spiral pipe 3 while also providing good heat insulation, reducing heat loss and energy consumption. A control panel 24 is provided on the outer wall of the jacket layer 2. The control panel 24 integrates a high-precision temperature sensor, an intelligent controller, and an operation display screen, allowing operators to intuitively set the target preheating temperature via the touch screen. The temperature is monitored in real time, including the temperature of the raw material in tank 1 and the temperature of the medium in heating box 7, to achieve intelligent temperature control. A spiral tube 3 is installed inside the jacket layer 2. The spiral tube 3 is sleeved on the outer wall of tank 1 and is made of copper with excellent thermal conductivity. Its spiral layout that fits tightly against the outer wall of tank 1 greatly increases the contact area with tank 1, making heat exchange more complete and uniform. One end of the spiral tube 3 is fixedly connected to the input tube 4, and the other end of the spiral tube 3 is fixedly connected to the output tube 5. Both the input tube 4 and the output tube 5 use quick-connect connectors, which facilitate quick disassembly and assembly with external pipelines and facilitate equipment maintenance and repair. A fixing ring 6 is fixedly connected to the outer wall of the jacket layer 2. The heating box 7 is fixedly connected to the outer wall of the fixing ring 6. A heating component is installed inside the heating box 7, and a mixing component is installed inside the tank 1. The heating assembly includes heating rods 8, which are made of high-temperature and corrosion-resistant nickel-chromium alloy heating wires with a stainless steel protective tube. They are characterized by high heating efficiency and long service life. Heating rods 8 are installed inside the heating chamber 7 and are evenly distributed inside the heating chamber 7, which can quickly and evenly heat the medium inside the chamber. A circulation pump 9 is fixedly connected to one side of the heating chamber 7. A heat extraction pipe 10 is fixedly connected to the input end of the circulation pump 9 and is installed inside the heating chamber 7. A heat delivery pipe 11 is fixedly connected to the output end of the circulation pump 9. One end of the heat delivery pipe 11 is fixedly connected to one end of the input pipe 4. The circulation pump 9 is a high-temperature centrifugal pump with stable flow and sufficient head. It can extract the high-temperature medium in the heating chamber 7 through the heat extraction pipe 10 and then efficiently deliver it to the input pipe 4 of the spiral tube 3 through the heat delivery pipe 11. This drives the medium to circulate between the spiral tube 3 and the heating chamber 7, continuously providing stable heat to the foam raw material in the tank 1.

[0020] Reference Figure 1 , Figure 4 and Figure 5The mixing assembly includes a rotating rod 15 and a stirring blade 25. The rotating rod 15 is rotatably connected inside the tank body 1, and one side of the stirring blade 25 is fixedly connected to the outer wall of the rotating rod 15. Driven by the rotating rod 15, the stirring blade 25 can efficiently stir the foam material in the tank, making the material more uniformly mixed. A motor 14 is fixedly connected to the top of the tank body 1. The motor 14 is a variable frequency speed control motor, which can flexibly adjust the speed of the rotating rod 15 according to different material mixing requirements to achieve precise stirring. The output end of the motor 14 is connected to the top of the rotating rod 15, and a stirring blade 25 is fixedly connected to the outer wall of the rotating rod 15. A connecting frame 16 has a support rod 17 fixedly connected to its side wall. A connecting rod 18 is fixedly connected to one end of the support rod 17, and a scraper 19 is fixedly connected to one side of the connecting rod 18. The outer wall of the scraper 19 contacts the inner wall of the tank 1. When the rotating rod 15 rotates, the connecting frame 16 and support rod 17 fixedly connected to the outer wall rotate synchronously. The connecting rod 18 and scraper 19 fixedly connected to one end of the support rod 17 also rotate together. The scraper 19 is made of wear-resistant rubber, and its outer wall tightly adheres to the inner wall of the tank 1. During rotation, it can effectively scrape off the raw materials adhering to the inner wall of the tank 1, avoiding the original... To prevent material residue and ensure uniform mixing of raw materials, while reducing waste and improving utilization, a support frame 20 is fixedly connected inside the tank 1. This frame, constructed from welded stainless steel angle steel, provides a stable structure and reliable support for the U-shaped tube 21. The bottom of the support frame 20 is fixedly connected to the U-shaped tube 21, which has multiple nozzles 22 at its bottom. These nozzles feature a fan-shaped spray design, ensuring even distribution of the injected cleaning solution throughout the tank 1. A water injection pipe 23 is fixedly connected to the outer wall of the U-shaped tube 21, passing through the tank 1 and the jacket layer 2. Connected to an external water source, after processing, clean water or cleaning fluid is injected into the U-shaped pipe 21 through the water injection pipe 23 and sprayed out through the nozzle 22, which can thoroughly and efficiently clean the inside of the tank 1, ensuring the cleanliness of the tank and preparing for the next raw material storage and preheating. The top of the heating box 7 is fixedly connected to a water inlet valve 12, and the bottom of the heating box 7 is fixedly connected to a drain valve 13. The water inlet valve 12 is used to replenish the heating medium into the heating box 7, while the drain valve 13 can quickly drain the medium in the heating box 7 when the equipment is maintained or the medium is replaced, which facilitates the daily maintenance and repair of the equipment.

[0021] Working principle: When using the jacketed constant temperature preheating tank for foam raw materials, first set the target preheating temperature through the control panel 24. Then, start the heating components in the heating box 7. The heating rod 8 starts working to heat the medium in the heating box 7. When the medium temperature reaches a certain level, the circulation pump 9 starts and extracts the high temperature medium in the heating box 7 through the heat extraction pipe 10. Then, it is transported to the input pipe 4 of the spiral tube 3 through the heat delivery pipe 11. After the high temperature medium enters the spiral tube 3, it flows along the spiral tube 3 sleeved on the outer wall of the tank body 1. The heat is transferred to the foam raw material in the tank body 1 through heat conduction. After the heat exchange is completed, the low temperature medium flows back to the heating box 7 from the output pipe 5 of the spiral tube 3. This cycle is repeated to achieve constant temperature preheating of the foam raw material in the tank body 1. When it is necessary to mix the foam raw materials, the motor 14 at the top of the tank 1 can be started. The motor 14 drives the rotating rod 15 to rotate, and the stirring blade 25 on the rotating rod 15 rotates accordingly to stir the raw materials. When the rotating rod 15 rotates, it also drives the connecting frame 16 and the support rod 17 to rotate. The connecting rod 18 and the scraper 19 at one end of the support rod 17 also rotate synchronously. The scraper 19 contacts the inner wall of the tank 1 and can scrape off any raw materials that may be attached to the inner wall of the tank 1, ensuring that the raw materials are mixed evenly and reducing residue. In addition, when it is necessary to clean the inside of the tank 1 after processing, liquid can be injected into the U-shaped tube 21 through the water injection pipe 23. The liquid is sprayed out through multiple nozzles 22 at the bottom of the U-shaped tube 21. The nozzles 22 facilitate cleaning the inside of the tank 1 and can clean the inside of the tank 1 more thoroughly.
