Description

Technical Field

[0001] This utility model relates to the field of polyphenylene sulfide production technology, and in particular to a polyphenylene sulfide polymerization reactor. Background Technology

[0002] Polyphenylene sulfide (PPS) is a high-performance thermoplastic engineering plastic. Due to its high temperature resistance, chemical corrosion resistance, excellent electrical properties, and flame retardancy, it is used in many fields. In the production process of PPS, a polymerization reactor is required for polymerization reaction. The polymerization reactor usually consists of a reactor body and a stirrer. The stirrer is used to uniformly mix the reactants, thereby improving the reaction efficiency.

[0003] However, the agitators in existing polyphenylene sulfide polymerization reactors are usually fixed inside the reactor body, which makes it inconvenient to disassemble and repair, resulting in poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide a polyphenylene sulfide polymerization reactor, which aims to solve the technical problem that in the prior art, the agitator of the polyphenylene sulfide polymerization reactor is usually fixedly installed inside the reactor body, which is inconvenient for disassembly and maintenance, resulting in poor practicality.

[0005] To achieve the above objectives, this utility model employs a polyphenylene sulfide polymerization reactor, comprising a reactor body, a discharge pipe, a rotating roller, a mounting rod, a sleeve, a fixed base, multiple support rods, bearings, a sealing assembly, two sets of stirring assemblies, and a discharge assembly. The discharge pipe is fixedly connected to the reactor body and located at the bottom of the reactor body. The reactor body has multiple grooves inside. One end of each of the multiple support rods is fixedly connected to the fixed base, and the other end of each of the multiple support rods is inserted into the corresponding groove and engaged with the reactor body. The sleeve is connected to the fixed base via the bearings. The mounting rod is fixedly connected to the sleeve and located at the upper end of the sleeve. Both sets of stirring assemblies are disposed on the outside of the mounting rods. The sealing assembly is disposed on the upper surface of the reactor body. One end of the rotating roller is fixedly connected to the mounting rod, and the other end of the rotating roller passes through the sealing assembly. The discharge assembly is disposed at the lower end of the sleeve.

[0006] The sealing assembly includes a vessel lid, a first flange, and a second flange. The first flange is fitted onto the upper end of the vessel body and is fixedly connected to the vessel body. The second flange is fitted onto the outside of the vessel lid and fits against the first flange.

[0007] Each set of stirring components includes a stirring plate and a clamping plate. One end of the clamping plate is fixedly connected to the stirring plate, and the other end of the clamping plate is clamped to the mounting rod.

[0008] The discharge assembly includes a rotating rod, a threaded rod, and a scraper. One end of the threaded rod is fixedly connected to the rotating rod, and the other end of the threaded rod is inserted into the sleeve and threadedly connected to the sleeve. The scraper is fixedly connected to the rotating rod and is located at the lower end of the rotating rod.

[0009] The mounting rod has two symmetrically arranged slots.

[0010] This utility model discloses a polyphenylene sulfide polymerization reactor. In practical use, multiple support rods are inserted into corresponding grooves, and then the reactants are added to the reactor body. The sealing assembly is then installed at the upper end of the reactor body, with the rotating roller passing through the sealing assembly. A drive device drives the rotating roller to rotate, which in turn drives the mounting rod to rotate. The mounting rod drives two sets of stirring assemblies to rotate, thereby stirring the reactants. Simultaneously, the mounting rod drives the sleeve to rotate, which in turn drives the discharge assembly to rotate, making the discharge of the reactants smoother through the discharge pipe. This method effectively solves the problem in the prior art where the stirrer of the polyphenylene sulfide polymerization reactor is usually fixed inside the reactor body, making it inconvenient to disassemble and maintain, resulting in poor practicality.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-4 ,in Figure 1 This is a structural schematic diagram of the present invention. Figure 2 This is a partial structural schematic diagram of this utility model. Figure 3 This is a partial structural schematic diagram of the present invention. Figure 4 This is a partial exploded view of the structure of this utility model.

[0019] This utility model provides a polyphenylene sulfide polymerization reactor, including a reactor body 101, a discharge pipe 103, a rotating roller 104, a mounting rod 105, a sleeve 107, a fixed base 108, multiple support rods 109, a bearing 118, a sealing assembly, two sets of stirring assemblies, and a discharge assembly. The discharge pipe 103 is fixedly connected to the reactor body 101 and located at the bottom of the reactor body 101. The interior of the reactor body 101 has multiple grooves 102. One end of each of the multiple support rods 109 is fixedly connected to the fixed base 108, and the other end of each of the multiple support rods 109 is inserted into the mounting rod 105. The corresponding groove 102 is engaged with the vessel body 101. The sleeve 107 is connected to the fixed seat 108 through the bearing 118. The mounting rod 105 is fixedly connected to the sleeve 107 and is located at the upper end of the sleeve 107. Both sets of the stirring components are disposed on the outside of the mounting rod 105. The sealing component is disposed on the upper surface of the vessel body 101. One end of the rotating roller 104 is fixedly connected to the mounting rod 105, and the other end of the rotating roller 104 passes through the sealing component. The discharge component is disposed at the lower end of the sleeve 107.

[0020] In this embodiment, multiple support rods 109 are inserted into the corresponding grooves 102. Then, the reactants are added to the vessel body 101. The sealing assembly is then installed at the upper end of the vessel body 101, with the rotating roller 104 passing through it. A driving device then rotates the rotating roller 104, which in turn rotates the mounting rod 105. The mounting rod 105 rotates the two sets of stirring assemblies, thereby stirring the reactants. Simultaneously, the mounting rod 105 rotates the sleeve 107, which in turn rotates the discharge assembly, allowing the reactants to be discharged more smoothly through the discharge pipe 103.

[0021] Furthermore, the sealing assembly includes a lid 110, a first flange 111, and a second flange 112. The first flange 111 is fitted onto the upper end of the vessel body 101 and is fixedly connected to the vessel body 101. The second flange 112 is fitted onto the outside of the lid 110 and fits against the first flange 111.

[0022] In this embodiment, by providing the first flange 111 and the second flange 112, it is convenient to connect the vessel cover 110 to the vessel body 101, and the vessel cover 110 seals the vessel body 101.

[0023] Furthermore, each of the stirring components includes a stirring plate 113 and a clamping plate 114, one end of the clamping plate 114 being fixedly connected to the stirring plate 113, and the other end of the clamping plate 114 being engaged with the mounting rod 105.

[0024] In this embodiment, the stirring plate 113 is connected to the mounting rod 105 by the clamping plate 114. The rotation of the mounting rod 105 drives the stirring plate 113 to rotate, thereby stirring the reaction materials.

[0025] Furthermore, the discharge assembly includes a rotating rod 115, a threaded rod 116, and a scraper 117. One end of the threaded rod 116 is fixedly connected to the rotating rod 115, and the other end of the threaded rod 116 is inserted into the sleeve 107 and threadedly connected to the sleeve 107. The scraper 117 is fixedly connected to the rotating rod 115 and is located at the lower end of the rotating rod 115.

[0026] In this embodiment, the rotating rod 115 is connected to the sleeve 107 by the threaded rod 116, and the rotating rod 115 is connected to the sleeve 107 by the rotation of the sleeve 107. The rotation of the sleeve 107 drives the rotating rod 115 to rotate, and the rotating rod 115 drives the scraper 117 to rotate, thereby preventing the reactant from clogging the discharge pipe 103.

[0027] Furthermore, the mounting rod 105 is symmetrically provided with two slots 106.

[0028] In this embodiment, the two card plates 114 are respectively inserted into the corresponding card slots 106, thereby deflecting the two stirring plates 113 along the axis of the mounting rod 105, which can improve the stirring effect.

[0029] The beneficial effects of this utility model are as follows: Multiple support rods 109 are inserted into the corresponding grooves 102, then the reactants are added to the reactor body 101, and then the reactor cover 110 is installed on the upper end of the reactor body 101, with the rotating roller 104 passing through the reactor cover 110. Then, the rotating roller 104 is driven to rotate by a driving device, which in turn drives the mounting rod 105 to rotate. The mounting rod 105 drives the two stirring plates 113 to rotate, thereby stirring the reactants. At the same time, the mounting rod 105 drives the sleeve 107 to rotate, which in turn drives the rotating rod 115 to rotate, and the rotating rod 115 drives the scraper 117 to rotate, making the reactants flow more smoothly when discharged through the discharge pipe 103. This method can effectively solve the problem in the prior art that the agitator of the polyphenylene sulfide polymerization reactor is usually fixedly installed inside the reactor body, which is inconvenient for disassembly and maintenance, resulting in poor practicality.

[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
