Especially in processes involving solid particle pretreatment and gas mixing, problems such as insufficient mixing, particle clogging, or low shearing efficiency are prone to occur. In addition, the structural design of existing devices is not conducive to rapid disassembly and maintenance, resulting in increased operating costs and shortened equipment life.
[0004] Therefore, it is necessary to design a high-efficiency wet shear pump for simultaneous online homogenization of gas, solid, and liquid phases to solve the above problems. Utility Model Content

Both insertion columns are fixedly inserted into the inside of the top crushing blades. The top of the feeding pipe is connected to a crushing screen pipe. The three crushing blades are rotatably disposed inside the crushing screen pipe, and a screen plate is fixedly connected inside the crushing screen pipe. A scraper is fixedly fitted onto the outer surface of the rotating shaft. A connecting flange is fixedly connected to the top of the crushing screen pipe, and an air inlet pipe is connected to the outer surface of the crushing screen pipe.
[0007] Preferably, the outer surface of the crushing screen tube is provided with a disassembly port, and the outer surface of the disassembly port is connected to a maintenance plate by bolt thread.
[0008] Preferably, the threaded sleeve is threaded onto the top end of the rotating shaft, and the bottom of the threaded sleeve is in contact with the top of the top crushing blade.
