Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a high-efficiency condensation and recovery device for the purification of methyl methacrylate. Background Technology

[0002] In the purification process of methyl methacrylate, the condensation recovery unit plays a crucial role, directly affecting the purity of the product and production efficiency. Traditional condensation recovery units generally use a mechanical transmission method to connect the scraper and the drive motor to clean the polymer from the inner wall of the condenser tube. However, this mechanical transmission method has significant drawbacks. During long-term operation, friction between mechanical parts leads to severe wear, causing rapid aging of components and a continuous decline in transmission efficiency, thus affecting the stable operation of the unit. Furthermore, leaks are prone to occur at the seals of the mechanical transmission structure, resulting not only in material waste but also potential safety hazards. Frequent maintenance and repairs are required. Replacing components leads to a significant increase in maintenance costs. In addition, traditional condensation devices have shortcomings in heat transfer and material handling. As production continues, methyl methacrylate polymers gradually accumulate on the inner wall of the condenser tubes. These polymers form an insulating layer, reducing heat transfer efficiency and severely affecting the condensation effect. Furthermore, traditional devices lack effective means of stirring the materials inside the tubes, resulting in uneven mixing and insufficient heat exchange. Ultimately, this leads to low purification and recovery efficiency of methyl methacrylate, making it difficult to meet the demands of modern industry for efficient and energy-saving production. To address these issues, we propose a high-efficiency condensation and recovery device for the purification of methyl methacrylate. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a highly efficient condensation and recovery device for the purification of methyl methacrylate, thus solving the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a high-efficiency condensation and recovery device for the purification of methyl methacrylate, comprising a condenser tube, a spiral scraper disposed inside the condenser tube, and a base fixedly mounted on the surface of the condenser tube near the spiral scraper, a drive magnetic disk rotatably mounted inside the base, and a motor fixedly mounted on the top of the base, and further comprising:

[0005] The spiral scraper uses magnetic coupling between the driven magnetic disk and the driving magnetic disk. When the motor drives the driving magnetic disk, non-contact transmission is achieved through magnetic force, avoiding the wear and leakage problems of traditional mechanical transmission.

[0006] Preferably, the output shaft of the motor extends through the interior of the base and is fixedly installed together with the drive magnetic disk. A bracket is fixedly installed in the middle of the motor, and the bottom end of the bracket is fixedly installed in the top of the base by multiple sets of mounting rods.

[0007] Preferably, a rotating shaft is provided on the side of the condenser tube near the spiral scraper, and the rotating shaft is fixedly installed inside the condenser tube by multiple sets of support rods.

[0008] Preferably, the spiral scraper includes a fixed rod, a fixed frame, and a driven magnetic disk. The driven magnetic disk is rotatably mounted on one side of the rotating shaft. The side of the driven magnetic disk away from the rotating shaft is tapered, and a fixed rod is fixedly mounted on the side of the driven magnetic disk away from the rotating shaft. Multiple sets of fixed frames are fixedly mounted on the fixed rod.

[0009] Preferably, a conical head is fixedly installed on the side of the fixed rod away from the driven magnetic disk, and a first mounting ring is fixedly installed on the side of the conical head near the fixed rod. The interior of the first mounting ring is fixedly installed together with the fixed rod by a set of fixing brackets, and a second mounting ring is fixedly installed on the side of the fixed rod near the driven magnetic disk by a set of fixing brackets.

[0010] Preferably, a spiral blade is fixedly installed between the first mounting ring and the second mounting ring, and the middle part of the spiral blade is fixedly installed together with a fixing rod by multiple sets of fixing brackets.

[0011] Preferably, multiple sets of magnets are fixedly installed inside the base and the driven magnetic disk, and the multiple sets of magnets are distributed in a cross shape with north and south poles inside the base and the driven magnetic disk.

[0012] Compared with the prior art, this utility model provides a highly efficient condensation and recovery device for the purification of methyl methacrylate, which has the following beneficial effects:

[0013] 1. This high-efficiency condensation recovery device for the purification of methyl methacrylate addresses the common problem of traditional condensation recovery devices that use mechanical transmission to connect the scraper and drive motor. Long-term operation can lead to wear, component aging, decreased transmission efficiency, and potential leaks at the seals, requiring frequent maintenance and component replacement. This device employs magnetic coupling transmission. The spiral scraper achieves non-contact transmission through a driven magnetic disk and a drive magnetic disk. When the motor drives the drive magnetic disk to rotate, the magnetic force from the cross-distributed magnets in the base and inside the magnetic disk drives the driven magnetic disk and scraper, avoiding wear caused by mechanical contact and eliminating the risk of seal leaks. Furthermore, this transmission method reduces energy loss between transmission components and improves overall operating efficiency.

[0014] 2. This high-efficiency condensation and recovery device for the purification of methyl methacrylate addresses the shortcomings of traditional condensation devices. Polymer buildup on the inner wall of the condenser tubes reduces heat transfer efficiency and affects condensation performance. Furthermore, the lack of effective material stirring leads to insufficient heat exchange and low purification and recovery efficiency. This device's spiral scraper not only tightly adheres to the inner wall of the condenser tube, continuously scraping away the attached methyl methacrylate polymer and keeping the tube wall clean, ensuring efficient heat transfer, but also stirs the material inside the tube during rotation, promoting uniform mixing and accelerating heat exchange. This assists in completing purification and condensation recovery. In addition, the conical head on the fixed rod guides and concentrates the material, optimizing the material flow path and ensuring more thorough processing within the condenser tube. Compared to traditional devices, this significantly improves the purification and recovery efficiency of methyl methacrylate. Attached Figure Description

[0044] Instructions for use

[0045] When the device is working, motor 3 starts, and its output shaft drives the drive magnetic disk 7 inside the base 2 to rotate stably. Motor 3 is fixed to the top of the base 2 by bracket 4 and mounting rod to reduce running vibration and ensure the smooth operation of drive magnetic disk 7. After drive magnetic disk 7 rotates, because there are multiple sets of magnets 15 with north and south poles intersecting inside the base 2 and driven magnetic disk 14, they influence each other through magnetic coupling, causing it to rotate continuously under the drive of magnetic field force. When driven magnetic disk 14 rotates, it drives the spiral scraper 6 fixed on it to rotate synchronously. Spiral scraper 6 is composed of fixed rod 11, fixed frame 12, spiral blade 13, etc. The rotating shaft 5 is fixed inside the condenser tube 1 by multiple sets of support rods to provide stable support for spiral scraper 6 and ensure that it does not deviate during rotation. During the continuous rotation of the blade 6, the spiral blade 13 closely adheres to the inner wall of the condenser tube 1. Through continuous rotation, it efficiently scrapes off the methyl methacrylate polymer adhering to the tube wall, preventing polymer accumulation from affecting heat transfer efficiency. At the same time, the rotating stirring action of the spiral blade 13 promotes uniform mixing of materials inside the tube, accelerates heat exchange, and assists in completing purification and condensation recovery. In addition, the conical head 8 on the fixed rod 11 guides and concentrates the materials during rotation, optimizing material flow. The first mounting ring 9 and the second mounting ring 10 cooperate with the fixed frame 12 to enhance the structural strength of the fixed rod 11, ensuring the stable, reliable, and continuous operation of the spiral scraper 6 and efficiently completing the condensation recovery work.
