Description

Technical Field

[0001] This utility model relates to the field of reactor stirring shaft technology, and in particular to a modular assembly reactor stirring shaft. Background Technology

[0002] A reaction vessel is a container for physical or chemical reactions. Through structural design and parameter configuration of the container, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved.

[0003] Existing bushings are usually fixed to the reactor, making disassembly and assembly inconvenient. To remove the worn bushing and replace it with a new wear-resistant bushing, the stirring shaft needs to be removed, which is cumbersome. In addition, during use, the gap between the stirring shaft and the bushing is prone to material accumulation and solidification, which seriously affects the service life of the bushing. Furthermore, the difficulty in disassembling and assembling the bushing can have a certain impact on actual production or experiments.

[0004] An existing patent (publication number: CN216382266U) provides a reactor stirring shaft fixing device. The reactor stirring shaft fixing device provided by this application completes the disassembly and replacement of the easily worn bushing that contacts the stirring shaft in a "half" manner. During the replacement of the easily worn bushing, it is not necessary to disassemble the stirring shaft and the fixing bushing. The whole process is simple, easy to operate, and time-saving.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, traditional stirring shafts are typically integral structures. If a problem occurs, the entire stirring shaft needs to be removed from the reactor during maintenance, which is difficult to operate and time-consuming. Furthermore, in the production process of an enterprise, various reactors of different specifications and models may be used, and the replacement of the stirring shafts used in conjunction with them is cumbersome.

[0006] To address this, a modular assembly reactor stirring shaft is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a modular assembly reactor stirring shaft, which can solve the problem that the existing traditional stirring shaft is usually an integral structure. Once a problem occurs, the entire stirring shaft needs to be removed from the reactor for maintenance, which is difficult to operate and takes a long time to maintain. At the same time, in the production process of an enterprise, various reactors of different specifications and models may be used, and the operation of replacing the stirring shaft used with them is cumbersome.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a modular assembly reactor stirring shaft, including a shaft rod, a stirring assembly bolted to the surface of the shaft rod, and a coupling assembly fixedly connected to the surface of the shaft rod;

[0009] The stirring assembly includes a bushing bolted to the surface of a shaft. A stirring arm is fixedly connected to the surface of the bushing. A fixed seat is fixedly connected to the side of the stirring arm away from the bushing. A stirring blade is bolted to the surface of the fixed seat.

[0010] Preferably, the coupling assembly includes a connecting section that is snapped onto the surface of the shaft, a coupling disc is fixedly connected to the top of the connecting section, and a connecting bolt is bolted inside the coupling disc.

[0011] Preferably, the number of the coupling disc and the connecting section are both set to two and they are interlocked with each other. The surface of the shaft is fixedly connected with a connector, and the interior of the connecting section is provided with a connecting groove for use with the connector.

[0012] Preferably, the coupling disc has a shaft hole inside for use with a connecting bolt, and the number of connecting bolts and shaft holes is set to several and evenly distributed inside the coupling disc.

[0013] Preferably, a connecting seat is fixedly connected to the surface of the bushing, and a mounting bolt is threadedly connected to the inside of the connecting seat. The mounting bolt passes through the connecting seat and extends into the interior of the connecting seat.

[0014] Preferably, the stirring arm is internally threaded with a fixing bolt, which passes through the stirring arm and the stirring blade and extends to the surface of the stirring blade. The bushing is internally fixedly connected with a positioning block, which is inserted into the inside of the shaft.

[0015] Preferably, the surface of the shaft is rotatably connected to a positioning seat, the number of the positioning seats is set to three and they are interlocked with each other, and the surface of the positioning seat is fixedly connected to a support column.

[0016] Preferably, a mounting base is fixedly connected to the side of the support column away from the positioning seat, and a positioning bolt is movably connected inside the mounting base.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application achieves the effect of easy transportation by setting up a mixing component, which can be assembled on site, reducing on-site installation time and workload, improving installation efficiency. When the mixing shaft fails, only the damaged part needs to be replaced, without disassembling and replacing the entire mixing shaft, thus reducing maintenance time and labor costs.

[0019] 2. This application achieves the transmission of power from the drive device to the shaft by setting a coupling assembly, thereby driving the stirring assembly to rotate, enabling corresponding stirring operations, improving the uniformity of the reaction and product quality.
