Description

Technical Field

[0001] The utility model relates to the technical field of BYD reactors, and particularly relates to an isolation and protection device for a BYD reactor. Background Technique

[0002] The BYD reactor is an important device in the production process of BDO new energy. It is equipped with a catalyst, a stirrer, a candle filter and a gas transmission pipeline inside. The catalyst needs to be replaced every three months during the operation of the BYD reactor. During this period, the candle filter and the gas transmission pipeline need to be removed. The gas transmission pipeline is installed at the bottom of the BYD reactor and is located on the second floor of the BYD framework. Its length is about 6m. During the process of removing this pipeline, the floor partition needs to be removed in advance, and then the pipeline removal operation is carried out. At the same time, there are many personnel performing other maintenance operations on the reactor. To prevent personnel from falling, the maintenance needs to be carried out in sequence and cannot be carried out synchronously. As a result, the maintenance work process is complex and time-consuming, and there are also relatively large safety risks. Therefore, avoiding floor removal and smoothly removing the gas transmission pipeline is the key to ensuring the smooth progress of the maintenance work and improving the maintenance efficiency. To solve the above problems, an isolation and protection device for a BYD reactor needs to be designed. Content of the Utility Model

[0003] The purpose of the utility model is to provide an isolation and protection device for a BYD reactor, so as to solve the problems in the above background technique that during the process of regularly replacing the catalyst in the BYD reactor, due to the long gas transmission pipeline, the overall construction period is long and the maintenance is complex.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An isolation and protection device for a BYD reactor, including a protective sleeve ring. One side of the protective sleeve ring is provided with an isolation frame, and an isolation cover is arranged inside the isolation frame. A positioning ring is fixed at the top end of the isolation cover, and a limiting block B is fixed at the top end of the isolation cover. An installation plate is fixed inside the protective sleeve ring, and limiting blocks A are fixed at the top ends of the installation plates. Side plates are fixed on one side of each limiting block A. A through hole is arranged inside the isolation cover, and a telescopic handle is connected through the inside of the through hole. A connecting rod is fixed at the top end of the telescopic handle.

[0005] Preferably, the limiting blocks A, the installation plates and the side plates are all symmetrically arranged about the central axis of the protective sleeve ring, and the cross section of the limiting block A is L-shaped.

[0006] Preferably, the cross section of the positioning ring is C-shaped, the cross section of the limiting block B is L-shaped, and the limiting block B is located on the side close to the isolation frame.

[0007] Preferably, the protective sleeve ring and the isolation frame are connected through a rotating component, and the rotating component is a three-axis hinge.

[0008] Preferably, a rotating groove is formed in the inner side wall of the isolation frame, an extension plate is fixed to the outer side of the isolation cover, and the extension plates are all rotatably connected to the rotating groove.

[0009] Preferably, the size of the extension plate is adapted to the size of the rotating groove, and the cross-sections of the extension plate and the rotating groove are both annular.

[0010] Preferably, the material of the protective sleeve is a flange sleeve joint, the materials of the isolation frame and the isolation cover are both circular steel plates, the material of the positioning ring is flat steel coil paper, and the materials of the connecting rod and the telescopic handle are round steel.

[0011] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0012] The protective sleeve avoids the scraping of the gas transmission pipe by the grille plate. Through the connection or separation of the limiting block B and the limiting block A, the fixing and separation of the protective sleeve, the isolation frame and the isolation cover on the isolation and protection device are realized. When the protective sleeve is integrally separated from the isolation frame, the gas transmission pipe is kept unobstructed. By closing the isolation frame and the isolation cover of the isolation and protection device, other maintenance personnel and goods in transit can pass normally and operate synchronously. This transformation solves the problems of complex working procedures and long time consumption in the maintenance work of the gas transmission pipeline of the BYD reactor, and at the same time avoids the risk of maintenance personnel falling from a height and improves the maintenance efficiency.
