Description

Technical Field

[0001] This utility model relates to the technical field of high-pressure reactor sealing equipment, and in particular to a high-pressure reactor sealing device that allows the passage of wires. Background Technology

[0002] Autoclaves are common pressurization equipment in research experiments and production processes. The safety of autoclaves during use is one of the most critical concerns in production processes or experimental research. Autoclaves are typically used to create high-pressure environments, and many mechanical devices are housed within them, including those with complex electrical wiring. These devices usually require connection to the outside to obtain data. Traditional autoclave designs either lack openings to maintain a tight seal, preventing the passage of electrical wires from the autoclave to the outside, or, while some designs include openings to allow wires to pass through, these often suffer from poor sealing, higher costs, and negatively impact the safety and environmental stability of production experiments. Therefore, this invention designs a pressure vessel sealing device that allows wires to pass through, addressing the problems mentioned in the background section. Utility Model Content

[0003] In view of this, in order to solve the problems of poor sealing and high cost when allowing wires to pass through, the present invention provides a sealing device for a high-pressure reactor that allows wires to pass through.

[0004] An embodiment of this utility model provides a sealing device for a high-pressure reactor with a passable wire, comprising a main body bolt, a secondary body bolt, and an electrical wire;

[0005] The lower end face of the main bolt is provided with a stud for sealing connection with the autoclave, and the upper end face is provided with a metal washer and a polytetrafluoroethylene washer between it and the secondary bolt. The secondary bolt is connected to the main bolt by a number of connecting bolts to press the metal washer and the polytetrafluoroethylene washer together. The electrical wire passes through the main bolt, the metal washer, the polytetrafluoroethylene washer and the secondary bolt in sequence and extends to the outside.

[0006] Furthermore, the upper end face of the main bolt is provided with a receiving hole, the stud body is provided with a channel, and the channel communicates with the receiving hole. The metal washer and the polytetrafluoroethylene washer are sequentially received in the receiving hole, with the metal washer close to the main bolt and the polytetrafluoroethylene washer close to the secondary bolt.

[0007] Furthermore, the metal gasket and the polytetrafluoroethylene gasket are each provided with a first through hole, and the first through holes on the two are interconnected.

[0008] Furthermore, the outer wall of the stud is fitted with a polytetrafluoroethylene gasket for insulation.

[0009] Furthermore, the secondary bolt has a protrusion on the side near the main bolt, and the protrusion has a second through hole, which communicates with each of the first through holes.

[0010] Furthermore, the protrusion abuts against the polytetrafluoroethylene gasket.

[0011] Furthermore, the secondary bolt is provided with a plurality of locking through holes, and the main bolt is provided with a plurality of locking threaded holes. Each locking through hole corresponds to each locking threaded hole, and each connecting bolt is sequentially accommodated in each locking through hole and engages with each locking threaded hole for threaded locking.

[0012] Furthermore, the electrical wire extends to the outside after passing through the channel, each of the first through holes, and the second through hole in sequence.

[0013] Furthermore, the upper end face of the main bolt does not contact the lower end face of the secondary bolt.

[0014] Furthermore, the number of connecting bolts is four, the number of locking through holes is four, and the number of locking threaded holes is four.

[0015] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: In the high-pressure reactor sealing device with a permeable wire, firstly, a polytetrafluoroethylene (PTFE) gasket insulating washer is fitted onto the main bolt, achieving the sealing function of the high-pressure reactor. The gasket possesses extremely high strength and toughness, isolating the internal and external material exchange caused by the connection between the high-pressure reactor body and the sealing device, thus ensuring the sealing performance of the high-pressure reactor device; the gasket has excellent heat insulation performance, isolating the heat exchange between the inside and outside of the high-pressure reactor, ensuring the stability of the internal temperature of the high-pressure reactor; the gasket also possesses excellent high-temperature resistance, corrosion resistance, and wear resistance, making it suitable for long-term use in the connection between the high-pressure reactor body and the sealing device. First, the sealing device is designed to withstand various conditions without damage. Second, the main bolts and their studs are fixed to the outer surface of the autoclave. The high precision and smoothness of the contact surface reduce the cost of fixing the sealing device and the difficulty of wiring installation. The convenient fixing method also increases the flexibility of the sealing device. Third, the main bolts and auxiliary bolts are fixedly connected by four connecting bolts, ensuring the sealing device's strength and the body's sealing performance. This design also has lower technical difficulty and cost, facilitating large-scale and commercial use in industrial production, biopharmaceuticals, and food manufacturing. Fourth, the metal gaskets and PTFE gaskets are separate from other components of the sealing device. This reduces the difficulty of passing wires through the sealing device and allows for the fixing and separation of the wires, avoiding wiring problems caused by wire tangling and shaking.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] Please refer to Figures 1 to 4 An embodiment of this utility model provides a sealing device for a high-pressure reactor with a permeable wire, including a main bolt 1, a secondary bolt 2, and an electrical wire 6 extending from inside the high-pressure reactor.

[0023] In this embodiment, the main bolt 1 is located below the auxiliary bolt 2. In actual working conditions, the lower end of the main bolt 1 is connected to the external high-pressure vessel, and the upper end is connected to the auxiliary bolt 2.

[0024] Furthermore, a stud is integrally formed on the lower end face of the main bolt 1, and a channel is provided inside the stud. A polytetrafluoroethylene washer insulating gasket 7 is sleeved on the outside of the stud. In actual working conditions, the main bolt 1 is connected to the autoclave through the stud on it. During connection, the polytetrafluoroethylene washer insulating gasket 7 is pressed tightly against the autoclave to achieve a sealing effect. The electrical wires 6 inside the autoclave extend out through the channel inside the stud.

[0025] The upper end face of the main bolt 1 is provided with a receiving hole, and the channel inside the bolt body is connected to the receiving hole; furthermore, a metal washer 3 and a polytetrafluoroethylene washer 4 are provided between the main bolt 1 and the secondary bolt 2, and both the metal washer 3 and the polytetrafluoroethylene washer 4 are accommodated in the receiving hole. One end face of the metal washer 3 abuts against the bottom surface of the receiving hole, and the other end abuts against one end face of the polytetrafluoroethylene washer 4. The other end face of the polytetrafluoroethylene washer 4 abuts against the secondary bolt 2.

[0026] Furthermore, both the metal gasket 3 and the polytetrafluoroethylene gasket 4 are provided with a first through hole, and the first through hole on the metal gasket 3 and the first through hole on the polytetrafluoroethylene gasket 4 are interconnected. At the same time, each of the first through holes on the metal gasket 3 and the polytetrafluoroethylene gasket 4 is connected to the channel. In this way, the electrical wire 6 inside the autoclave can continue to extend outward through each of the first through holes after extending out through the channel in the stud body.

[0027] The lower end face of the sub-bolt 2 is provided with a protrusion, and the protrusion is provided with a second through hole. The second through hole is connected to each of the first through holes, and the lower end of the protrusion abuts against the upper end face of the polytetrafluoroethylene gasket 4. In this way, when the conductor 6 extends out through each of the first through holes, it can extend to the outside through the second through hole. Moreover, the metal gasket 3 and the polytetrafluoroethylene gasket 4 can also play a sealing role in the process of the conductor 6 extending out. Combined with the polytetrafluoroethylene gasket insulating gasket 7, the entire extension of the conductor 6 can be sealed.

[0028] The secondary bolt 2 has several locking through holes, and the main bolt 1 has several locking threaded holes. Each locking through hole corresponds to each locking threaded hole. At the same time, each locking through hole is sequentially fitted with a connecting bolt 5. Each connecting bolt 5 is sequentially threaded through each locking through hole and each locking threaded hole to lock together, thereby locking the main bolt 1 and the secondary bolt 2 together. At the same time, the metal washer 3 and the polytetrafluoroethylene washer 4 can also be locked and pressed together.

[0029] The working method of the high-pressure reactor sealing device with permeable wire in this embodiment is as follows: the device is sealed and fixedly connected to the high-pressure reactor through the stud on the main bolt 1 and the polytetrafluoroethylene gasket insulating pad 7. At the same time, the wire 6 inside the high-pressure reactor can extend to the outside through the channel, each first through hole and the second through hole in the stud. The extension process of the wire 6 is ensured to be sealed by the compression metal pad 3 and the polytetrafluoroethylene pad 4.
