Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a cleaning device for the main pipeline of a tubular reactor. Background Technology

[0002] A tubular reactor is a continuous flow chemical reaction device with a long, narrow pipe structure. Reactants enter from one end and exit from the other, undergoing a chemical reaction.

Static mixers or catalyst-packed beds can be installed inside the reactor to enhance mass transfer and reaction efficiency. However, the presence of catalyst-packed beds and other components inside the reactor may cause scaling on the inner wall of the pipe, reducing the pipe's inner diameter and affecting the liquid flow rate, thus impacting the reaction efficiency within the pipe.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a cleaning device for the main pipeline of a tubular reactor, including a support frame 1. The support frame 1 is a cuboid frame structure with open ends, welded from profiles. Connecting beams 2 are provided on the front and rear sides of the interior of the support frame 1. Three sets of support beams 3 are provided between two connecting beams 2. Support wheels 5 are rotatably connected to the front and rear sides of each set of two support beams 3 through bearing seats 4. Drive shafts 6 are respectively connected through the support wheels 5 on the front and rear sides. A transfer box 7 is provided on one side of the interior of the support frame 1. Two drive shafts 6 are respectively connected to the power output end of the transfer box 7. A power motor 8 is provided at the power input end of the transfer box 7. One end of the main shaft 9 is provided at the power output end of the power motor 8. A cleaning roller 10 is provided on the main shaft 9. A movable frame 11 is provided on the other side of the interior of the support frame 1.

[0018] In use, a support beam 3 is fixedly installed inside the support frame 1 via a connecting beam 2. A support wheel 5 is rotatably connected to the support beam 3 via a bearing seat 4. The main pipe of the tubular reactor to be cleaned is placed between the two support wheels 5, and the cleaning roller 10 is inserted into the pipe. The main shaft 9 is supported on the outside by the movable frame 11, and the axial position of the main pipe is limited. A drive shaft 6 is installed between the front and rear support wheels 5. The power of the motor 8 is transmitted to the two drive shafts 6 through the transfer box 7, so that the front and rear support wheels 5 rotate in the same direction and speed, thereby driving the main pipe on the support wheels 5 to rotate. The power of the motor 8 is transmitted to the main shaft 9 through the transfer box 7, so that the main shaft 9 rotates in the same direction as the two support wheels 5, thereby driving the cleaning roller 10 to rotate and clean the inner wall of the main pipe. The rotation direction of the main pipe is opposite to the rotation direction of the cleaning roller 10, thereby improving the cleaning effect.

[0019] The lower end of the movable frame 11 is rotatably connected to the support frame 1 via a pivot. The upper end of the movable frame 11 is provided with a connecting edge 12, which is connected to the support frame 1 via bolts. The other end of the main shaft 9 is provided with a support bearing 13, which is connected to the support frame 1 via bolts. The movable frame 11 is designed to be rotatably opened, which facilitates the installation of the main pipeline and the overall cleaning equipment when opened. After the main pipeline is installed, the movable frame 11 is fixed to the support frame 1 via the connecting edge 12, and the support bearing 13 is provided on the support frame 1 to support the outer end of the main shaft 9.

[0020] A support platform 14 is provided on one side of the support frame 1 at a position corresponding to the transfer case 7. The transfer case 7 is fixedly connected to the support platform 14 by bolts, providing support for the transfer case 7 and the power motor 8.

[0021] The front and rear sides of the support frame 1 and the upper and lower ends of the connecting beam 2 are provided with reinforcing beams 15. The reinforcing beams 15 are correspondingly arranged with the support wheel 5 to improve the overall structural strength and prevent the support wheel 5 from rotating outward and flying off after being damaged.
