Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam film production technology, specifically to a foam film production equipment. Background Technology
[0002] The existing foamed film production process involves adding raw materials into a reactor, heating the reactor to the required temperature, and then performing a specific chemical reaction to generate foamed material as the raw materials move toward the outlet. The foamed material is then extruded and stretched to form a foamed film.
[0003] However, existing reactors rely solely on heating devices to regulate temperature, resulting in inaccurate temperature control and potential for localized overheating or underheating, which can negatively impact the quality of the foamed film. Furthermore, different stages of the reaction require varying temperatures for different parts of the reactor, necessitating temperature control in different areas of the reactor. This places higher demands on the temperature control capabilities of existing reactors. Utility Model Content

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a foamed film production equipment, including: a production unit and a temperature control unit.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] To address the technical problem of insufficient temperature control in existing foamed film production equipment, this invention provides a foamed film production equipment that can precisely regulate temperature and generate multiple zones with different temperatures within a single reactor to meet more complex production needs.
[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a foamed film production equipment in one embodiment of the present invention. The foamed film production equipment includes a production unit 1 and a temperature control unit 2.
[0022] Production unit 1 includes a synthesis reactor 11, which has an inlet, an outlet, and a reaction chamber located at both the inlet and outlet. Raw materials enter the reaction chamber through the inlet and then move towards the outlet under external force. A chemical reaction occurs during this movement, generating foamed material. The foamed material is extruded from the outlet and, after stretching and shaping, forms a foamed film.
[0023] Multiple temperature control units 2 are arranged sequentially on the synthesis reactor 11 along the material movement direction. Each temperature control unit 2 includes a heating module 21 and a cooling module 22, used to heat up and cool down the reaction chamber, respectively. This ensures that different areas of the reaction chamber are at different temperatures to meet the process requirements of different production stages. Simultaneously, if the temperature in a certain area becomes too high, the cooling module 22 can promptly cool it down. Compared to reducing the heating power of the heating module 21 and waiting for natural cooling, this method provides faster adjustment and more precise temperature control.
[0024] In some embodiments, the synthesis reactor 11 is a horizontally arranged columnar structure, and the production unit 1 further includes a screw conveyor 12, which is arranged at one end of the synthesis reactor 11 to drive the material from the feed inlet to the discharge outlet. In other embodiments, other conveying equipment can also be used to drive the material movement, as long as it can withstand the production environment inside the synthesis reactor 11. Continuous feeding can also be used, allowing the subsequent raw materials to push the preceding raw materials towards the discharge outlet. However, the screw conveyor 12 can more accurately control the material's forward speed, i.e., the time the material spends in different areas within the reaction chamber, thus improving the production quality of the foamed film.
[0025] In some embodiments, the production unit 1 further includes a feeding device 13 and a feeding device 14. The synthesis reactor 11 also has several feeding ports located between the inlet and the outlet. The feeding device 13 is connected to the inlet and is used to deliver raw materials into the reaction chamber. The feeding device 14 is connected to the feeding port and is used to add other raw materials during the production process as needed.
[0026] The temperature control unit 2 includes a heating module 21 and a cooling module 22. The heating module 21 includes a heat source and a casing. The casing is arranged close to and around the outer wall of the synthesis reactor 11. The heat source is embedded in the casing to heat the reactor 11. The casing serves to protect the heat source and transfer heat. Therefore, the side that is in contact with the heated reactor 11 is made of a material with good thermal conductivity, and the side that is away from the heated reactor 11 is made of a material with good thermal insulation properties.
[0027] In some embodiments, the heat source includes a heating wire and two terminals. The heating wire is embedded in the enclosure and arranged around the synthesis reactor 11. The two ends of the heating wire are connected to the two terminals, and one end of each terminal extends through the enclosure to the outside of the enclosure. By connecting the terminals to an external power supply, the heating wire can generate heat. At the same time, the heating efficiency of the heating wire can be controlled by controlling the current.
[0028] In other embodiments, a flow channel is formed within the package surrounding the synthesis reactor. Two interfaces are formed at both ends of the flow channel on the surface of the package. The heat source is a high-temperature fluid flowing through the flow channel, such as water, oil, or steam. An external heating device first heats the fluid to a certain temperature before it flows through the flow channel, thereby heating the synthesis reactor 11.
[0029] In some embodiments, the cooling module 22 includes a water pipe 221, a nozzle 222, and a valve 223. Multiple nozzles 222 are arranged around and towards the outer wall of the synthesis reactor 11. The water pipe 221 connects each nozzle 222 to an external water supply device. The valve 223 is located on the water pipe 221 and is used to control whether the water pipe 221 is open. When the temperature in a certain area of the synthesis reactor 11 is too high, the corresponding cooling module 22 starts working, the valve 223 opens, and the nozzles 222 spray cooling water towards the synthesis reactor 11 to cool it down.
[0030] In some embodiments, the temperature control unit 2 further includes a temperature measuring module 23, which has a temperature measuring end connected to the outer wall of the synthesis reactor 11 or embedded in the synthesis reactor 11, for detecting the temperature of the reaction chamber, thereby guiding the heating module 21 and the cooling module 22 to regulate the temperature.
[0031] In a preferred embodiment, valve 223 is an electrically controlled valve, and the temperature control unit 2 further includes a controller 24. The temperature measuring module 23 is connected to the controller 24 for signal transmission to transmit temperature data to the controller 24. The controller 24 is connected to the valve 223 for signal control to control the opening or closing of the valve 223.
[0032] In some embodiments, the foamed film production equipment further includes a containment vessel 3, which is spaced apart from and arranged around the synthesis reactor 11. Although the synthesis reactor 11 can withstand thermal shock, the containment vessel 3 is provided as a precaution to prevent injury should the outer wall of the synthesis reactor 11 rupture. The containment vessel 3 also blocks the high-temperature steam and splashing high-temperature droplets generated by the cooling module 22 during operation, preventing injury. It is easy to understand that the containment vessel 3 is open, or has an opening at the top for discharging high-temperature steam, while also having the necessary connecting structures to support components such as the synthesis reactor 11 and the cooling module 22.
[0033] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
