Since the reactor internal parts are designed with special-shaped cylinders and run for a long time in a high-temperature environment, their material design is special and difficult to clean. In order to ensure the quality and stable operation of the equipment, the internal parts must be cleaned regularly to prevent the accumulation of carbon on the surface. However, it is difficult to thoroughly clean the internal parts with current technology, which limits their service life. Utility Model Content

[0003] Based on the above background, the purpose of the utility model is to provide a cleaning device for the internal and external parts of a reactor which can thoroughly clean the internal parts and is easy to operate, so as to solve the problems described in the background technology.

[0004] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0005] A cleaning device for internal and external parts of a reactor, comprising a roller frame and a support ring, wherein the support ring is located at the upper part of the support ring, and the support ring is rotatably matched with the roller frame;

[0006] The roller frame comprises a base and two rotating units, the rotating units are arranged at both ends of the top of the base, and the two rotating units are arranged in mirror symmetry;

[0008] Due to the complex structure of the inner net, it is divided into two layers, the outer layer is Johnson net, there are gaps between the wires, the inner net has a large diameter of about 2.5m, and the outer wire is soft and needs to be rolled for cleaning. The outer net has Johnson net wire inside and steel plate (with longitudinal ribs) outside. The outer net has a larger diameter of about 4m and needs to be rolled for cleaning.

[0009] Therefore, when the device is used to clean the inner and outer nets, the support ring is first placed between the two rotating units so that the support ring contacts the first rotating wheel and the second rotating wheel, the inner and outer nets are then placed inside the support ring, and the roller frame is then fixed to the inner and outer nets.

[0010] The intermediate shaft is driven to rotate, and the rotation of the intermediate shaft drives the first rotating wheel and the first gear to rotate. Since the first gear, the transition gear and the second gear are meshingly connected, and the second gear is connected to the second rotating wheel, when the intermediate shaft rotates, the first rotating wheel and the second rotating wheel will rotate at the same time, and the rotation of the first rotating wheel and the second rotating wheel drives the support ring to rotate, and then the support ring drives the inner net and the outer net to rotate. When the inner and outer nets rotate, the operator can flush the inner and outer nets.

[0015] Preferably, a sleeve coupling is arranged between the transmission shaft and the reducer, and the sleeve coupling is connected to the transmission shaft and the reducer.

[0016] Preferably, a slider coupling is arranged between the motor and the reducer, and the slider coupling is connected to the motor and the reducer.

[0017] Preferably, a steel plate is disposed inside the ring body, and the steel plate is welded to the ring body.

[0018] Because the contact between different materials can produce electrochemical reactions and cause material corrosion, a steel plate made of the same material as the Johnson mesh is welded on the inside of the ring body, which is the same material as the inner and outer meshes, to ensure that there is no electrochemical corrosion between the materials.

The frame 102-1 is connected to the base 101. The first rotating wheel 102-2 and the second gear 102-5 are arranged on the inner side of the frame 102-1. The first gear 102-4 is located on the side of the second gear 102-5 away from the middle of the base 101. The height of the first gear 102-4 is higher than the height of the second gear 102-5. The first rotating wheel 102-2 and the second rotating wheel 102-3 are both rotatably connected to the frame 102-1. The first rotating wheel 102-2 is provided with the first gear 102-4. The first gear 102-4 is located between the first rotating wheel 102-2 and the inner wall of the frame 102-1 A second gear 102-5 is provided between the second rotating wheel 102-3, and the second gear 102-5 is located between the second rotating wheel 102-3 and the inner wall of the frame 102-1, the first gear 102-4 is connected to the first rotating wheel 102-2, the second gear 102-5 is connected to the second rotating wheel 102-3, a transition gear 102-6 is provided between the first gear 102-4 and the second gear 102-5, and the transition gear 102-6 is meshed and connected with the first gear 102-4 and the second gear 102-5, the first gear 102-4, the second gear 102-5 and the transition gear 102-6 are all rotatably connected with the base 101, the first rotating wheel 102-2 is provided with an intermediate shaft 102-7, and the intermediate shaft 102-7 is connected with the first rotating wheel 102-2, the first gear 102-4 and the frame 102-1.

[0035] Due to the complex structure of the inner net, it is divided into two layers, the outer layer is Johnson net, there are gaps between the wires, the inner net has a large diameter of about 2.5m, and the outer wire is soft and needs to be rolled for cleaning. The outer net has Johnson net wire inside and steel plate (with longitudinal ribs) outside. The outer net has a larger diameter of about 4m and needs to be rolled for cleaning.

[0036] When the device is used to clean the inner and outer nets, the support ring 2 is first placed between the two rotating units 102 so that the support ring 2 is in contact with the first rotating wheel 102-2 and the second rotating wheel 102-3, and then the inner and outer nets are placed inside the support ring 2, and then the roller frame 1 is fixed to the inner and outer nets.

[0037] like Figure 5 and Figure 6As shown, the support ring 2 includes a ring body 201 and a connecting portion 202, the ring body 201 and the connecting portion 202 are an integral structure, and the cross-sections of the ring body 201 and the connecting portion 202 are H-shaped. The ring body 201 is the connection place between the support ring 2 and the inner and outer nets, and the connecting portion 202 is the connection place between the support ring 2 and the rotating unit 102.

A slider coupling 5 is arranged between the motor 302 and the reducer 301, and the slider coupling 5 is connected to the motor 302 and the reducer 301. The motor 302 provides power, which is transmitted through the reducer 301 and the transmission shaft 303, and finally drives the first rotating wheel 102-2 and the second rotating wheel 102-3 to rotate.

[0040] A rubber plate that is not prone to corrosion can also be installed between the roller frame 1 and the internal parts to ensure that the roller frame 1 and the internal parts rotate at the same time, making it easier to clean the internal parts.

[0041] The operating steps of the reactor internal and external parts cleaning device of the utility model are as follows:

[0042] First, place the support ring 2 between the two rotating units 102 so that the support ring 2 contacts the first rotating wheel 102-2 and the second rotating wheel 102-3, then place the inner and outer nets inside the support ring 2, and then fix the roller frame 1 to the inner and outer nets.

[0043] The intermediate shaft 102-7 is driven to rotate, and the rotation of the intermediate shaft 102-7 drives the first rotating wheel 102-2 and the first gear 102-4 to rotate. Since the first gear 102-4, the transition gear 102-6 and the second gear 102-5 are meshingly connected, and the second gear 102-5 is connected to the second rotating wheel 102-3, when the intermediate shaft 102-7 rotates, the first rotating wheel 102-2 and the second rotating wheel 102-3 will rotate at the same time, and the rotation of the first rotating wheel 102-2 and the second rotating wheel 102-3 drives the support ring 2 to rotate, and then the support ring 2 drives the inner net and the outer net to rotate. When the inner and outer nets rotate, the operator can flush the inner and outer nets.
