Technical Field

[0001] The utility model relates to the technical field of pipeline reactors, in particular to a titanium alloy pipeline reactor with high production efficiency. Background Technique

[0002] A pipeline reactor is a tubular continuous operation reactor with a very large length-diameter ratio. Such a reactor can be very long, for example, the reactor tube length for propylene dimerization is measured in kilometers; the shorter ones, such as pipeline reactors in fine chemical industry, generally have a length of dozens of meters.

[0003] After retrieval, the patent with the publication number of CN219377154U discloses a pipeline reactor combination assembly, including a base and a tubular reactor body. Two rectangular mounting plates for installing the tubular reactor body are arranged on the upper surface of the base. This device can clean the inner wall of the pipeline. However, there are the following deficiencies in use:

[0004] 1. The above device can only clean the inner wall of straight pipes and cannot clean the inner wall of bent pipes. Dirt is likely to accumulate at the turning points of the inner wall of bent pipes, and the cleaning is not thorough enough.

[0005] Therefore, we propose a titanium alloy pipeline reactor with high production efficiency. Content of the Utility Model

[0006] The purpose of the utility model is to solve the shortcomings in the prior art that the device can only clean the inner wall of straight pipes and cannot clean the inner wall of bent pipes, and dirt is likely to accumulate at the turning points of the inner wall of bent pipes, and the cleaning is not thorough enough, and to propose a titanium alloy pipeline reactor with high production efficiency.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A titanium alloy pipeline reactor with high production efficiency, including:

[0009] Multiple bent pipes and multiple straight pipes, the multiple bent pipes and multiple straight pipes are arranged alternately and connected by flanges;

[0010] A first fixing block is fixedly arranged on the inner wall of the bent pipe. A bent rod is fixedly arranged on the outer wall of the first fixing block. A plurality of movable blocks are rotatably connected to the outer wall of the bent rod. First cleaning brushes are fixedly arranged on the outer walls of the movable blocks for cleaning the inner wall of the bent pipe. A linkage mechanism is arranged between adjacent two movable blocks;

[0011] Two second fixing blocks are fixedly arranged on the inner wall of the straight pipe. A rotating rod is rotatably penetrated between the second fixing blocks. A plurality of second cleaning brushes are fixedly arranged on the outer wall of the rotating rod for cleaning the inner wall of the straight pipe. A second guiding rod is fixedly arranged on the outer wall of the bottom end of the rotating rod for cooperating with the linkage mechanism;

[0012] The driving mechanism is arranged on the outer wall of the straight tube and is used to provide power for the rotating rod.

[0013] In a possible design, the linkage mechanism includes a connecting block and a first guide rod, which are respectively fixed on the outer walls of two adjacent movable blocks. A guide groove is opened through the surface of the connecting block. The diameter of the first guide rod is smaller than the width of the guide groove, and the first guide rod and the second guide rod are both matched with the guide groove.

[0014] In a possible design, the driving mechanism includes a mounting plate and multiple fixed tubes, the multiple fixed tubes are respectively fixed and penetrate the outer walls of multiple straight tubes, the inner walls of the fixed tubes are rotatably connected with inner rods, the outer walls of the inner rods are each fixed with at least one synchronous wheel, and a synchronous belt is transmission-connected between two adjacent synchronous wheels on the same side, one end of the multiple inner rods and the outer wall of the rotating rod are fixed with bevel gears, and the adjacent bevel gears are meshed with each other, the mounting plate is fixed on the outer wall of one of the straight tubes, and a motor is fixed on the inner wall of one side of the mounting plate, and the output shaft of the motor is fixed to one of the inner rods.

[0017] In a possible design, the curved pipe and the straight pipe are both made of titanium alloy.

[0018] In the present application, when in use, the motor is started, and the motor drives the corresponding inner rod to rotate. Under the action of the synchronous wheel and the synchronous belt, multiple inner rods rotate at the same time. Under the action of the bevel gear, multiple rotating rods rotate at the same time, so that the second cleaning brush cleans the inner wall of the straight pipe. At the same time, the rotating rod drives the second guide rod to rotate, and the second guide rod drives the corresponding connecting block to rotate, thereby causing multiple movable blocks to rotate successively, so that the first cleaning brush cleans the inner wall of the curved pipe and stirs the internal fluid to speed up the reaction.

[0019] Beneficial effects:

[0020] In the utility model, the titanium alloy pipe reactor with high production efficiency can clean the inner walls of the straight pipe and the curved pipe at the same time by setting the first cleaning brush and the second cleaning brush, thereby avoiding dirt residue and making the cleaning more thorough;
