Description

Technical Field

[0001] This utility model relates to the field of polystyrene production technology, specifically to a preheater for polystyrene production. Background Technology

[0002] In the polymer materials industry, polystyrene, as a general-purpose thermoplastic, is widely used in packaging materials, electronic and electrical appliance housings, and building decoration due to its advantages of being lightweight, easy to process, and cost-controllable. The production process of polystyrene places strict requirements on the preheating of raw materials: styrene monomer, as the core raw material, needs to be preheated to a specific temperature range before entering the polymerization reactor.

[0003] The prior art discloses a polystyrene production preheater with publication number CN219037091U, comprising a preheater and a heating cylinder fixedly connected to the outer surface of the preheater. A motor is fixedly connected to one side of the top of the preheater via a connecting plate. Both sides of the bottom of the preheater's inner cavity are rotatably connected to stirring columns via bearings. The top of the stirring columns penetrates the preheater and extends to the outside of the preheater. This utility model relates to the field of polystyrene production technology. In this polystyrene production preheater, the motor drives the left stirring column to rotate, which in turn drives the right stirring column via a belt, causing two threaded blades to rotate. These blades agitate the polystyrene inside the preheater upwards, allowing the polystyrene to remain in the preheater for a longer period.

[0004] The aforementioned preheater for polystyrene production can effectively preheat polystyrene, ensuring more thorough and rapid heating and significantly improving its efficiency. However, this preheater cannot adjust the cross-sectional area of ​​the heating gas based on the internal temperature of the production cylinder, and it cannot achieve negative feedback regulation of flow rate and temperature. Consequently, it cannot guarantee that the preheating temperature meets the requirements, resulting in poor performance during use. Improvements are needed in these areas. Utility Model Content

[0019] Please see Figure 1-4 The present invention provides the following technical solution: A preheater for polystyrene production includes a production cylinder 1, a heat treatment cylinder 2 disposed on the side of the production cylinder 1, a temperature control and adjustment component 3 disposed on the surface of the heat treatment cylinder 2, and a heat insulation component 4 disposed on the surface of the production cylinder 1.

[0020] The temperature control assembly 3 includes a gas storage tank 302, which is fixedly connected to the front of the heating treatment cylinder 2. A connector 301 is fixedly connected inside the gas storage tank 302. A connecting pipe 303 is fixedly connected to the right side of the connector 301, and a negative pressure suction component 304 is fixedly connected to the right side of the connecting pipe 303. A connecting cylinder 306 is fixedly connected to the top of the heating treatment cylinder 2. A heating ring pipe 305 is fixedly connected to the surface of the connecting cylinder 306. An exhaust pump 307 is fixedly connected to the top of the connecting cylinder 306. A hollow tube is fixedly connected to the top of the exhaust pump 307. A delivery pipe 308 is fixedly connected to the left side of the hollow tube. A connecting housing 309 is fixedly connected to the end of the delivery pipe 308 away from the hollow tube. A connecting ring 310 is fixedly connected to the left side of the connecting housing 309. A rotating shaft 311 is slidably connected inside the connecting ring 310. A gripping wheel 312 is fixedly connected to the left side of the production cylinder 1. A support rectangular block 314 is fixedly connected to the top left side of the production cylinder 1. A scale ring 313 is fixedly connected to the top of the support rectangular block 314. A circular plate 315 is fixedly connected to the right side of the rotating shaft 311. An elastic ring pad 316 is fixedly connected to the surface of the circular plate 315. The diameter of the gripping wheel 312 is adapted to the inner diameter of the scale ring 313. The gripping wheel 312 is slidably connected to the inner ring of the scale ring 313. The angle between the inner circular plate 315 and the elastic ring pad 316 can be determined by comparing the position of the gripping wheel 312 with that of the scale ring 313, which facilitates precise adjustment of the ventilation volume and ensures normal operation of the device. The diameter of the rotating shaft 311 is adapted to the inner diameter of the connecting ring 310, ensuring that it can fit the internal rotation of the connecting ring 310, reducing gaps and preventing air leakage. The diameter of the elastic ring pad 316 is adapted to the inner diameter of the connecting housing 309.

[0021] The insulation component 4 includes a spiral flow channel 401, an aluminum silicate fiber insulation layer 402, a limiting bracket 403, a connecting cover plate 404, a mounting base 405, and mounting bolts 406. The spiral flow channel 401 is connected to the inside of the production cylinder 1. A driving stepper motor is fixedly connected inside the production cylinder 1. The spiral flow channel 401 is fixedly connected to the output shaft of the driving stepper motor. The aluminum silicate fiber insulation layer 402 is fixedly connected to the surface of the production cylinder 1. The limiting bracket 403 is fixedly connected to the surface of the production cylinder 1. The connecting cover plate 404 is fixedly connected to the top of the production cylinder 1. The mounting base 405 is connected to the top of the connecting cover plate 404. The mounting bolts 406 are threadedly connected to the inside of the mounting base 405 and the top of the connecting cover plate 404. The mounting base 405 has a threaded groove inside, and the connecting cover plate 404 has a connecting screw hole with the same diameter as the threaded groove on its top.

[0022] Preheating of the production cylinder 1 is required during use. Therefore, the negative pressure suction device 304 extracts gas into the inner wall of the gas storage tank 302. Then, the exhaust pump 307 is activated to generate suction, drawing the air into the connecting cylinder 306. The heating ring pipe 305 surrounding the surface of the connecting cylinder 306 is opened, and the gas inside the connecting cylinder 306 is heated. After heating, the gas enters the conveying pipe 308 and then into the connecting housing 309. The cross-sectional area of ​​the gas flow is adjusted according to the temperature inside the production cylinder 1. The flow rate of the gas can be adjusted by changing the angle of the circular plate 315 and the elastic ring pad 316. To increase the flow rate, the gripping wheel 312 can be used to rotate the rotating shaft 311, thereby rotating the circular plate 315 and the elastic ring pad 316. The circular plate 315 and the elastic ring gasket 316 are rotated to face the vertical direction, at which point the gas flow rate is at its maximum. Conversely, when the circular plate 315 and the elastic ring gasket 316 are horizontal, the elastic ring gasket 316 contacts the inner wall of the connecting shell 309, blocking the entry of hot air and realizing negative feedback regulation of flow rate and temperature. This ensures that the preheating temperature meets the requirements and can be adjusted in real time to ensure the normal operation of the device. The production cylinder 1 is divided into upper and lower ends. The bottom of the upper production cylinder 1 is provided with a mounting seat 405. When in use, the mounting seat 405 can be aligned with the top of the connecting cover plate 404, the threaded groove and the threaded connection hole can be aligned, and then the mounting bolt 406 can be screwed into the mounting seat 405 and the connecting cover plate 404 to complete the installation. During installation, the limiting bracket 403 can be used for positioning, which plays a role in heat dissipation and maintenance after processing, ensuring the normal operation of the device.
