Description

Technical Field

[0001] This application relates to the field of reactor technology, specifically a PFA lining device for a chemical reactor. Background Technology

[0002] A chemical reactor is a closed container used for chemical reactions. Its main structure includes a vessel body, a stirring device, a heating device, a cooling device, and a sealing device. Materials are mixed and reacted through stirring, heating, and cooling. During the use of a chemical reactor, it often comes into contact with corrosive media such as strong acids, strong alkalis, and strong oxidizing agents, and faces high temperature and high pressure working conditions.

[0003] However, most existing chemical reactors are made of stainless steel, which is in direct contact with the reaction medium. Although it has a certain strength, it is easily corroded after long-term use, which leads to contamination of the reaction medium and damage to the reactor structure. This not only affects product quality but also requires frequent replacement of the reactor, increasing production costs. Utility Model Content

[0004] The purpose of this invention is to provide a PFA lining device for a chemical reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A PFA liner device for a chemical reactor includes a base plate, four support legs fixedly connected to the upper surface of the base plate, a support plate fixedly connected to the upper surface of the four support legs, a reactor body fixedly connected inside the support plate, a PFA liner assembly installed inside the reactor body, and a disassembly mechanism fixedly connected to the outer surface of the reactor body.

[0006] As a further embodiment of this utility model: a discharge pipe is fixedly connected to the outer surface of the reaction vessel body, and a control valve is installed inside the discharge pipe.

[0007] As a further embodiment of this utility model: the PFA liner assembly includes a PFA liner inner shell, and an mounting plate is fixedly connected to the upper surface of the PFA liner inner shell.

[0008] As a further improvement of this utility model: the outer surface of the mounting plate is provided with four first threaded holes, and four nuts are fixedly embedded on the outer surface of the mounting plate.

[0009] As a further embodiment of this utility model: each of the first threaded holes is internally threaded with a first threaded rod, and the outer surfaces of the four first threaded rods are jointly threaded with a cover plate, and a sealing ring is installed on the bottom surface of the cover plate.

[0010] As a further embodiment of this utility model: the outer surface of the PFA inner liner shell is fixedly connected to a conduit, and the outer surface of the conduit is adapted to the interior of the discharge pipe.

[0011] As a further improvement of this utility model: the disassembly mechanism includes four fixing plates, each fixing plate having a second threaded hole on its outer surface, each second threaded hole having a second threaded rod threadedly connected inside, and the outer surface of each second threaded rod being adapted to the inside of the nut.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This PFA liner device for chemical reactors allows the PFA liner component to directly contact the reaction medium, effectively isolating the stainless steel material of the reactor body from the reaction medium. This solves the problem of reaction medium contamination and reactor structure damage caused by corrosion in traditional stainless steel reactors, ensuring the purity and stable quality of the final product. By engaging the second threaded rod with the second threaded hole of the nut, the PFA liner component can be quickly separated from the reactor body, avoiding frequent replacement of the reactor body and reducing production costs.

[0015] Please see Figures 1-4In this embodiment of the present invention, a PFA liner device for a chemical reactor includes a base plate 1. Four support legs 2 are fixedly connected to the upper surface of the base plate 1. A support plate 3 is fixedly connected to the upper surface of the four support legs 2. A reactor body 4 is fixedly connected inside the support plate 3. A PFA liner assembly 5 is installed inside the reactor body 4. A disassembly mechanism 6 is fixedly connected to the outer surface of the reactor body 4. A discharge pipe 7 is fixedly connected to the outer surface of the reactor body 4. A control valve 8 is installed inside the discharge pipe 7. The cooperation of the support legs 2 and the support plate 3 can stably support the reactor body 4, preventing the reactor from directly contacting the ground and causing bottom corrosion or wear. The discharge pipe 7 transports the reaction products discharged by the conduit 58 to subsequent processing equipment. The control valve 8 can precisely control the opening and closing of the discharge pipe 7.

[0016] The PFA liner assembly 5 includes a PFA liner inner shell 51. A mounting plate 52 is fixedly connected to the upper surface of the PFA liner inner shell 51. Four first threaded holes 53 are formed on the outer surface of the mounting plate 52. Four nuts 54 are fixedly embedded on the outer surface of the mounting plate 52. A first threaded rod 55 is threaded into the interior of each first threaded hole 53. A cover plate 56 is threaded onto the outer surface of the four first threaded rods 55. A sealing ring 57 is installed on the bottom surface of the cover plate 56. A conduit 58 is fixedly connected to the outer surface of the PFA liner inner shell 51. The outer surface of the conduit 58 is adapted to the interior of the discharge pipe 7. The PFA liner inner shell 51 directly connects to the discharge pipe 7. The reactor body 56 is made of chemically inert PFA material to prevent media from being contaminated by metal ions generated by corrosion of the reactor body 4, thus ensuring product purity. On the other hand, it completely transfers the risk of corrosion to itself, protecting the structure of the reactor body 4 from damage. The first threaded hole 53 allows workers to install the cover plate 56 through the first threaded rod 55. The sealing ring 57 is made of a chemically resistant elastic material. After the cover plate 56 is fixed, the sealing ring 57 will be located at the inner top of the PFA inner shell 51 to seal it. The conduit 58 ensures that the product is always in contact with the PFA inner shell 51 during the discharge process.

[0017] The disassembly mechanism 6 includes four fixing plates 61. Each fixing plate 61 has a second threaded hole 62 on its outer surface. Each second threaded hole 62 is threaded with a second threaded rod 63. The outer surface of each second threaded rod 63 is adapted to the inside of the nut 54. The cooperation between the second threaded hole 62 and the second threaded rod 63 makes it easy for workers to disassemble or install the PFA inner liner shell 51.

[0018] The working principle of this utility model is as follows: First, the base plate 1 is fixedly installed through the mounting holes. At this time, the reactor body 4 is stabilized above the base plate 1 by the support legs 2, ensuring that the reactor body 4 will not shift due to vibration or the weight of the medium during operation. Next, the PFA inner liner shell 51 is placed inside the reactor body 4, so that the conduit 58 is inserted into the discharge pipe 7 of the reactor body 4, ensuring that the subsequent product discharge channel is unobstructed. Then, the mounting plate 52 is attached to the top of the reactor body 4, and the PFA inner liner shell 51 is rotated so that the nut 54 corresponds to the second threaded hole 62. Then, the second threaded hole 62 is... The threaded rod 63 is rotatably installed inside the second threaded hole 62 and the nut 54. At this time, the PFA inner shell 51 will be limited to prevent the PFA inner shell 51 from shaking during the production process. At this time, the product to be processed can be added into the PFA inner shell 51. Finally, the first threaded rod 55 is used to install the cover plate 56 above the mounting plate 52 through the first threaded hole 53. Through the sealing ring 57, the PFA inner shell 51 will be in a sealed state. During processing, by adding a stirring component above the cover plate 56, the product inside the PFA inner shell 51 can be stirred.

[0019] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
