Description

Technical Field

[0001] This utility model relates to the field of polystyrene material production technology, specifically to a production apparatus for preparing polystyrene materials with different crosslinking densities. Background Technology

[0002] Polystyrene, a widely used thermoplastic, has a crucial influence on its properties due to its crosslinking density. Polystyrene with different crosslinking densities can be used in various fields such as packaging, electronics, and construction.

[0003] Currently, existing polystyrene production equipment has many shortcomings in preparing products with different crosslinking densities. On the one hand, traditional equipment has difficulty in accurately controlling various parameters in the crosslinking reaction process, resulting in poor precision in crosslinking density control, which cannot meet the application scenarios with strict requirements for material performance. On the other hand, existing equipment does not have good control over the addition method and mixing uniformity of crosslinking agents during the production process. Uneven addition of crosslinking agents will lead to inconsistent crosslinking degrees within the polystyrene material, resulting in large performance fluctuations. Moreover, the process of switching between products with different crosslinking densities is cumbersome, requiring a lot of time for equipment adjustment and parameter resetting, which seriously affects production efficiency and increases production costs. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned polystyrene material production equipment, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a production apparatus for preparing polystyrene materials with different crosslinking densities, which solves the problems of existing polystyrene material production apparatuses, such as difficulty in accurately controlling crosslinking density, uneven mixing of crosslinking agents, and cumbersome product switching processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An apparatus for producing polystyrene materials with different crosslinking densities includes a tank body. A support plate is fixedly installed inside the tank body.

[0011] Furthermore, a baffle is fixedly provided on the inner wall of the connecting pipe.

[0012] Preferably, the outer wall of the connecting pipe is fixedly provided with a heat insulation layer.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model, by installing pumps and flow control valves at the bottom of each tank in the raw material storage unit, can precisely control the delivery amount of styrene monomer, initiator, and crosslinking agent, thereby achieving precise control of the crosslinking density of polystyrene and meeting the material performance requirements of different application scenarios. Compared with traditional devices, it greatly improves the control accuracy of crosslinking density and can stably produce products that meet the needs of high-end fields. The baffle plate fixed on the inner wall of the connecting pipe can initially turbulently mix the raw materials during the delivery process. Combined with the stirring device in the reactor, the raw materials are fully mixed, effectively solving the problem of inconsistent crosslinking degree in polystyrene material caused by uneven addition of crosslinking agent, reducing product performance fluctuations and improving product quality stability.

[0015] 2. This utility model allows for convenient control of each component via a control panel. When switching between producing polystyrene products with different crosslinking densities, no complex equipment adjustments are required; only relevant parameters need to be changed through the control panel. This simplifies the switching process, saves significant time, improves production efficiency, and reduces production costs. The additive storage tank allows for the addition of different additives according to production needs, expanding the product's performance and application range. Furthermore, the bottom pipe of the additive storage tank extends directly into the reactor, enabling the additives to participate in the reaction quickly and ensuring effective addition.

[0016] 3. The design of the cleaning tank and cleaning pipe in this utility model facilitates the cleaning of styrene monomer tanks, initiator tanks, and crosslinking agent storage tanks, avoiding residual contamination of raw materials from different batches of production, ensuring the stability of product quality, and extending the service life of the equipment. The insulation layer on the outer wall of the connecting pipe can reduce heat loss of raw materials during transportation, ensuring the temperature stability of raw materials when entering the reactor, providing stable initial conditions for the crosslinking reaction, which is conducive to improving reaction efficiency and product quality.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a production apparatus for preparing polystyrene materials with different crosslinking densities.

[0025] This utility model provides, for example Figure 1-3The apparatus shown is for preparing polystyrene materials with different crosslinking densities. It includes a tank 1, with a support plate 2 fixed inside. A raw material storage unit is fixed to the top of the support plate 2. The raw material storage unit includes a styrene monomer tank 3, an initiator tank 4, and a crosslinking agent storage tank 5. Connecting pipes 6 are fixed to the bottom of the styrene monomer tank 3, initiator tank 4, and crosslinking agent storage tank 5, and a pump body 7 is fixed to the bottom of these tanks. A flow control valve 8 is fixed to the wall of the connecting pipe 6, which is connected to the outlet of the pump body 7. A reaction vessel 9 is fixed to the bottom of the tank 1, and a stirring device is fixed to the bottom of the reaction vessel 9. A control panel 10 is fixed to one side of the tank 1, and a discharge port 11 is fixed to the bottom of the tank 1. A valve body 12 is fixed to the outer wall of the discharge port 11. When using this apparatus to prepare polystyrene materials with different crosslinking densities, the operator first sets the parameters such as the delivery rate of each raw material, stirring time, and stirring speed through the control panel 10. After starting the apparatus, the pump body 7 begins to work. The raw materials in the styrene monomer tank 3, initiator tank 4, and crosslinking agent storage tank 5 are transported to the reactor 9 through the connecting pipe 6. The flow control valve 8 precisely controls the flow rate of each raw material according to the set parameters. When the raw materials flow through the connecting pipe 6, the turbulence 20 on the inner wall causes turbulence in the raw materials, resulting in preliminary mixing. The heat insulation layer 21 on the outer wall reduces heat loss. If additives are needed, they can be added to the reactor 9 through the additive storage tank 15. At the same time, the motor 13 drives the stirring rod 14 to rotate, which fully stirs the materials in the reactor 9, so that the raw materials and additives are evenly mixed and crosslinking reaction occurs. After the reaction is completed, the valve body 12 is opened, and the prepared polystyrene material is discharged from the outlet 11. When it is necessary to clean the raw material storage tanks, the switch valve 19 is opened, and the cleaning liquid in the cleaning tank 17 enters the styrene monomer tank 3, initiator tank 4, and crosslinking agent storage tank 5 through the cleaning pipe 18 to clean them. After cleaning, the switch valve 19 is closed. By adjusting the parameters such as the conveying amount of each raw material, polystyrene materials with different crosslinking densities can be prepared to meet different application requirements.

[0026] To achieve a more uniform blend, such as Figure 3 As shown, the stirring device includes a motor 13 and a stirring rod 14. The motor 13 is fixedly installed at the bottom of the tank 1, and the stirring rod 14 is fixedly installed at the output end of the motor 13.

[0027] And to facilitate the addition of additives, such as Figure 1 As shown, an additive storage tank 15 is fixedly provided on the top of the support plate 2, and the bottom tube of the additive storage tank 15 extends into the reaction vessel 9.

[0028] For easier cleaning, such as Figure 1As shown, a bracket 16 is fixedly installed on the top of the tank, a cleaning tank 17 is fixedly installed on the top of the bracket 16, a cleaning pipe 18 is fixedly installed at the bottom of the cleaning tank 17, one end of the cleaning pipe 18 is connected to the styrene monomer tank 3, the initiator tank 4 and the crosslinking agent storage tank 5, and a switch valve 19 is fixedly installed on the body of the cleaning pipe 18.

[0029] Finally, for better heat preservation, such as Figure 1-2 As shown, a baffle 20 is fixedly provided on the inner wall of the connecting pipe 6, and a heat insulation layer 21 is fixedly provided on the outer wall of the connecting pipe 6.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
