The hydrocyclone currently used by the company mainly includes a shell, an end cover, multiple cyclone tubes, and a large-hole plate and a small-hole plate arranged in parallel in the shell. The large-hole plate and the small-hole plate are respectively provided with evenly arranged large holes and small holes for fixing the heads and tails of multiple cyclone tubes. The centers of the large holes and small holes are coaxial. The heads and tails of the cyclone tubes are both provided with O-rings. The head of the cyclone tube is provided with a head groove axially, and the groove side wall of the head groove is provided with a disassembly hole. The shell is provided with an annular flange at one end close to the large-hole plate, and is connected to the end cover flange through the flange.

[0003] When installing the cyclone tube of the hydrocyclone, pass the tail of the cyclone tube from the large hole on the large hole plate to the small hole on the small hole plate, and then use a hammer to hit the head of the cyclone tube until the O-rings at the head and tail of the cyclone tube are respectively stuck in the large hole of the large hole plate and the small hole of the small hole plate, and then connect the end cover to the shell flange; when disassembling, remove the end cover connected to the shell, use a tool with a hook head, hook the disassembly hole from the head groove of the cyclone head, and pull the head and tail of the cyclone tube out of the large hole and the small hole respectively.

[0004] At present, when the cyclone tube is installed and used by existing tools or methods, there is a problem that the head of the cyclone tube is easily damaged due to repeated hammering of the head of the cyclone tube or excessive hammering force; when disassembling, the cyclone tube is stuck in the large hole and the small hole because sludge condenses on the large hole and the small hole after long-term use. It is very difficult to manually pull out the cyclone tube, and it is also easy to cause damage to the sealing rings at the head and tail of the cyclone tube; especially when the diameter of the cyclone tube is large, it is time-consuming and laborious to install and remove it by manual knocking.
