Description

Technical Field

[0001] This utility model relates to the technical field of PMMA vacuum devolatilization devices, specifically a PMMA vacuum devolatilization device. Background Technology

[0002] The PMMA vacuum devolatilization unit is a specialized device used in the production process of polymethyl methacrylate (PMMA). It reduces the system pressure through a vacuum environment, thereby efficiently removing residual volatile components from the material. Its core function is to control the volatile content within the process requirements while ensuring the quality of PMMA products.

[0003] Currently, among existing technologies, Chinese Patent No. CN221867401U discloses a PMMA vacuum devolatilization device. This device performs devolatilization in a vacuum environment, which can lower the boiling point of volatile components, making them easier to vaporize. This helps reduce energy consumption and improve devolatilization efficiency. The vaporized volatile components are condensed in a condenser and collected in a collection bucket, which facilitates subsequent processing of these components, such as recycling or safe disposal, thereby achieving efficient resource utilization and environmental protection. However, in actual use, the condenser plates of this device are fixedly connected. During the PMMA devolatilization process, residual oligomers and impurities easily condense on the surface of the condenser plates. The fixed connection makes it difficult to disassemble the condenser plates. Cleaning can only be done by wiping the surface or simple rinsing, which cannot deeply remove stubborn dirt in crevices and dead corners. Long-term accumulation will lead to a decrease in the heat transfer efficiency of the condenser plates and a decrease in devolatilization efficiency. In view of this, we propose a PMMA vacuum devolatilization device. Utility Model Content

[0004] The main objective of this invention is to provide a PMMA vacuum devolatilization device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a PMMA vacuum devolatilization device, comprising a base, a devolatilization tank, a heat dissipation box, and a collection box fixedly connected to the top of the base, a tank cover being provided on the devolatilization tank, a conveying pipe being connected to the tank cover, the end of the conveying pipe away from the tank cover being connected to the collection box, and the middle of the conveying pipe passing through the heat dissipation box, an auxiliary mechanism being provided on the heat dissipation box, the auxiliary mechanism including a rotating rod being rotatably connected to the heat dissipation box.

[0006] Preferably, a rotating block is fixedly connected above the rotating rod, and the rotating block is connected to the heat sink via a torsion spring.

[0007] Preferably, both side walls of the heat sink are provided with placement slots.

[0008] Preferably, the placement slot is connected to a placement plate, and the end of the placement plate is provided with a snap-fit ​​groove.

[0009] Preferably, the delivery pipe is clamped with a heat sink, and the heat sink is provided with a groove, a through slot and a through hole.

[0010] Preferably, a water tank is fixedly connected to the heat sink, with an inlet pipe and an outlet pipe connected to both ends of the water tank. By first moving the two sets of rotating blocks outward, the rotating blocks are rotated out of the locking groove, thereby releasing the position limit on the placement plate. Then, the placement plate can be pulled out upward, thereby releasing the position limit on the water tank. Then, pulling upward allows the water tank and the heat sink below to be removed for cleaning and maintenance. By moving the rotating blocks outward, the groove below the heat sink needs to be aligned with the delivery pipe for insertion, and the inlet pipe and outlet pipe need to be aligned with the placement groove for insertion. After insertion, the placement plate is inserted into the placement groove. After insertion, the rotating blocks are released, and under the elastic reset action of the torsion spring, the rotating blocks will be driven to engage with the locking groove at the end of the placement plate, thereby completing the installation and fixation of the placement plate, and thus completing the installation and fixation of the heat sink.

Then, the placement plate can be pulled out upward, thereby releasing the position limit of the water tank. Then, the water tank and the heat sink below can be taken out by pulling upward, so as to clean and maintain it.

[0014] (2) The PMMA vacuum desorption device moves the rotating block outward, so that the groove under the heat sink is aligned with the delivery pipe for insertion, and the water inlet pipe and water outlet pipe are aligned with the placement slot for insertion. After insertion, the placement plate is inserted along the placement slot. After insertion, the rotating block is released, and under the elastic reset action of the torsion spring, the rotating block will be driven to engage into the engagement slot at the end of the placement plate, thereby completing the installation and fixing of the placement plate, and thus completing the installation and fixing of the heat sink.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4This utility model proposes a PMMA vacuum devolatilization device, including a base 1. A devolatilization tank 2, a heat dissipation box 7 and a collection box 8 are fixedly connected above the base 1. The devolatilization tank 2 is provided with a lid 3. A conveying pipe 6 is connected to the lid 3. The end of the conveying pipe 6 away from the lid 3 is connected to the collection box 8, and the middle of the conveying pipe 6 passes through the heat dissipation box 7. An auxiliary mechanism 9 is provided on the heat dissipation box 7. The auxiliary mechanism 9 includes a rotating rod 91, which is rotatably connected to the heat dissipation box 7.

[0025] In this embodiment of the utility model, in order to enable the auxiliary mechanism 9 to operate better, a rotating block 92 is fixedly connected above the rotating rod 91. The rotating block 92 is connected to the heat sink 7 by a torsion spring 93. The heat sink 7 has placement slots 94 on both side walls. Placement plates 95 are inserted into the placement slots 94. The end of the placement plate 95 is provided with a snap-fit ​​slot 96. The conveying pipe 6 is snap-fitted with a heat sink 98. The heat sink 98 is provided with a groove 99, a through groove 910 and a through hole 911. The through groove 910 and the through hole 911 facilitate the faster dissipation of the heat source in the conveying pipe 6.

[0026] Furthermore, a water tank 97 is fixedly connected to the heat sink 98. The water tank 97 has an inlet pipe 912 and an outlet pipe 913 connected to its two ends. By first moving the two sets of rotating blocks 92 outwards, the rotating blocks 92 are rotated out of the locking groove 96, thus releasing the positional limitation on the placement plate 95. Then, the placement plate 95 can be pulled out upwards, releasing the positional limitation on the water tank 97. Pulling it upwards allows the water tank 97 and the heat sink 98 below to be removed for cleaning and maintenance. By moving the rotating blocks 92 outwards, the groove 99 below the heat sink 98 needs to be aligned with the delivery pipe 6 for insertion, and the inlet pipe 912 and outlet pipe 913 need to be aligned with the placement groove 94 for insertion. After insertion, ... The placement plate 95 is inserted into the placement groove 94. After insertion, the rotating block 92 is released. Under the elastic reset action of the torsion spring 93, the rotating block 92 will be driven to engage into the engagement groove 96 at the end of the placement plate 95, thereby completing the installation and fixation of the placement plate 95, and then completing the installation and fixation of the heat sink 98. The base 1 is equipped with a vacuum pump 5. The vacuum pump 5 is connected to the degassing tank 2 by an extraction pipe 4. The aforementioned vacuum pump 5, extraction pipe 4, delivery pipe 6 and collection box 8 are similar in principle to those mentioned in Chinese Patent (PMMA Vacuum Degassing Device) with authorization announcement number CN221867401U, and achieve the same effect. They are existing public technical means in this field, and will not be described in detail here.

[0027] In this utility model, when it is necessary to disassemble and maintain the heat sink 98, the two sets of rotating blocks 92 must first be pushed outwards to rotate the rotating blocks 92 out of the locking groove 96, thereby releasing the position limit on the placement plate 95. Then, the placement plate 95 can be pulled out upwards, thereby releasing the position limit on the water tank 97. Then, pulling upwards will remove the water tank 97 and the heat sink 98 below for cleaning and maintenance. When it is necessary to install the heat sink 98, first push the rotating blocks 92 outwards to remove the rotating blocks 92 out of the locking groove 96. 2. Move it outwards, align the groove 99 below the heat sink 98 with the delivery pipe 6 and insert it. Align the water inlet pipe 912 and the water outlet pipe 913 with the placement slot 94 and insert them. After insertion, insert the placement plate 95 along the placement slot 94. After insertion, release the rotating block 92. Under the elastic reset action of the torsion spring 93, the rotating block 92 will be driven to engage with the engagement slot 96 at the end of the placement plate 95, thus completing the installation and fixation of the placement plate 95, and thus completing the installation and fixation of the heat sink 98.
