Description

Technical Field

[0001] This utility model belongs to the field of chemical vapor permeation technology, and in particular relates to an easy-to-disassemble gas distributor. Background Technology

[0002] A vertical chemical vapor infiltration reactor is a device used to manufacture high-performance composite materials. This reactor is designed so that gas can enter from the bottom and permeate evenly into a preform placed inside the reactor by gravity or an auxiliary gas flow mechanism, thereby achieving precursor gas decomposition and deposition of the desired material inside the preform.

[0003] In vertical reactors, the reaction gas is usually introduced through a gas distributor. After long-term operation, the gas distributor may need to be cleaned or replaced due to problems such as particle deposition and accumulation of chemical reaction byproducts. However, in the existing technology, the gas distributor is usually fixed at the bottom of the reactor, which makes disassembly and assembly inconvenient. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 As shown, Figure 1 The diagram shown is an overall schematic diagram of the reactor and this device in the embodiment.

[0024] The gas distributor described in this application is used in a vertical reactor, which can be used to prepare composite materials by chemical vapor infiltration and chemical vapor deposition. By introducing substrate particles and reactive gases into the interior of the vertical reactor and controlling the internal conditions of the vertical reactor, the reactive gases react and deposit on the surface of the substrate particles or penetrate into the internal micropores of the substrate particles.

[0025] See Figure 1 and Figure 4 The reactor 1 includes a cone 2 at the bottom, and the bottom opening of the cone 2 is a straight section 201. A gas distributor is detachably mounted on the straight section 201 of the reactor 1.

[0026] like Figure 2 , Figure 3 , Figure 4 As shown, Figure 2 The diagram shown is an overall schematic of the gas distributor in the embodiment; Figure 3 The diagram shown is a partial cross-sectional view of the gas distributor in the embodiment; Figure 4 The diagram shown is a structural schematic of the gas distributor and the straight section in the embodiment.

[0027] This device includes:

[0028] Gas distributor body 10;

[0029] The mounting structure 20 includes a connecting part 21 disposed on the gas distributor body 10. The connecting part 21 is sleeved on the outside of the straight cylinder 201. A pad 22 is disposed on the inner side wall of the connecting part 21. A locking ring 23 is detachably disposed on the outer side wall of the connecting part 21.

[0030] The connecting part 21 is sleeved on the outside of the straight cylinder part 201, and the pad 22 is tightly attached to the outer side wall of the straight cylinder part 201. The locking ring 23 is sleeved on the outside of the connecting part 21 to fix the gas distributor body 10.

[0031] The gas distributor body 10 is provided with an air inlet and a gas guide path. The gas is blown from bottom to top and forms a vortex airflow inside the gas distributor body 10, which is then transported to the reactor 1 to achieve gas distribution. This will not be elaborated here.

[0032] This device is connected to the straight section 201 via the mounting structure 20.

[0033] In one embodiment, the shape of the connecting part 21 matches that of the straight cylindrical part 201 and the opening diameter of the connecting part 21 is larger than that of the straight cylindrical part 201. When the connecting part 21 is sleeved on the outside of the straight cylindrical part 201, the pad 22 is in close contact with the outer wall of the straight cylindrical part 201, which can ensure the sealing performance on the one hand; on the other hand, it can increase the friction between the two and improve the stability of the installation.

[0034] Specifically, the gasket 22 is typically made of a material with a certain degree of elasticity and excellent high-temperature resistance, such as ceramic fiber material molded into gaskets, which has good flexibility and excellent high-temperature resistance, while not disturbing the temperature stability inside the reactor. When the gasket 22 is compressed between the connecting part 21 and the straight cylinder part 201, it can fill the small irregular surfaces, thereby providing a more effective sealing effect and preventing gas leakage; and by increasing friction, it can effectively reduce the accidental movement of the gas distributor body 10 relative to the straight cylinder part 201, thereby ensuring the stability and normal operation of the equipment; in addition, the increased friction also makes the installation process simpler and faster.

[0035] The pad 22 also acts as a buffer, preventing wear or scratches that may be caused by direct contact between the connecting part 21 and the straight part 201, thus helping to extend the service life of the equipment.

[0036] The locking ring 23 is detachably sleeved on the outside of the connecting part 21, and serves to lock the connecting part 21 to fix the gas distributor body 10.

[0037] A limiting groove is provided on the outer wall of the connecting part 21, and the locking ring 23 is located in the limiting groove.

[0038] The limiting groove provides a precise positional reference for the locking ring 23, ensuring that it can be accurately installed in its predetermined position and thus effectively perform its locking function. By confining the locking ring 23 within the limiting groove, it can prevent positional displacement or loosening due to vibration or other reasons during equipment operation, thereby enhancing the stability of the overall structure. Furthermore, the presence of the limiting groove makes the installation of the locking ring 23 simpler, allowing workers to complete the positioning and fixing of the locking ring 23 more quickly and accurately, thus improving assembly efficiency.

[0039] The connecting part 21 is a deformable elastic sheet arranged at intervals;

[0040] There are gaps between the elastic sheets and each elastic sheet can deform independently.

[0041] like Figure 2 , Figure 3 , Figure 5 As shown, Figure 2 The diagram shown is an overall schematic of the gas distributor in the embodiment; Figure 3 The diagram shown is a partial cross-sectional view of the gas distributor in the embodiment. Figure 5 The diagram shown is a schematic representation of the locking ring in the embodiment (top view).

[0042] The locking ring 23 includes a semi-circular ring 231 and a ring 232. Both ends of the ring 231 and the ring 232 are provided with connecting parts 233. The connecting parts 233 of the ring 231 and the corresponding connecting parts 233 on the same side of the ring 232 are detachably connected.

[0043] The connector 233 includes a socket;

[0044] It also includes a bolt 234 that matches the insertion hole. After the bolt 234 is inserted into the insertion holes of the first ring hoop 231 and the second ring hoop 232 in sequence, the external thread of the end extending to the outside is fitted with a nut 235.

[0045] The locking ring 23 adopts a split structure of ring hoop one 231 and ring hoop two 232. Both parts are semi-circular rings, which together form a complete ring. The connecting parts 233 at both ends of ring hoop one 231 and ring hoop two 232 are the connection points between them. Each end has a corresponding connecting part 233 to ensure that ring hoop one 231 and ring hoop two 232 can be accurately mated. The insertion holes provided on the connecting parts 233 are used to insert bolts 234. The bolts 234 pass through the insertion holes on ring hoop one 231 and ring hoop two 232 and are connected to the nut 235 through threads, thereby achieving a tight fixation of the two ring hoop one 231 and ring hoop two 232.

[0046] Working principle: When this device is installed on the straight cylinder 201, the connecting part 21 of the gas distributor body 10 is sleeved on the outside of the straight cylinder 201, and the pad 22 inside it is tightly fitted to the outer side wall of the straight cylinder 201. Then, the first ring 231 and the second ring 232 are placed around the connecting part 21 and located in the limiting groove. Then, the connecting part 233 is aligned and fixed by bolts 234 and nuts 235. The connecting part 21 deforms under force and cooperates with the pad 22 to be locked on the straight cylinder 201 by the first ring 231 and the second ring 232 to achieve installation.

[0047] During disassembly, use a suitable tool (such as a wrench) to loosen and remove the nut 235, pull the bolt 234 out of the socket of the connecting part 233, and remove the loosened ring clamp 231 and ring clamp 232 from the connecting part 21. At this time, the connecting part 21 is no longer locked by external pressure. Slide the connecting part 21 out of the straight cylinder 201.

[0048] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
