Description

Technical Field

[0001] The utility model relates to the technical field of internal mixers, in particular to a cleaning mechanism for internal mixers. Background Art

[0002] Closed plastic mixer is called internal mixer for short. The main part of internal mixer is internal mixer, also called plastic mixer. The upper part is feeding device, the lower part is unloading device, and there is a bolt on the upper and lower parts. When the upper and lower bolts are closed, a closed plastic mixer is formed. There is a pair of rotors rotating in opposite directions in the plastic mixer. The cross section of the rotor is pear-shaped and the longitudinal direction is Z-shaped spiral. The rotor speed is slightly different. There is a constant speed ratio between the rotors and between the rotors and the inner wall of the plastic mixer.

[0003] Chinese patent publication number CN217916218U proposes "a refining chamber cleaning structure for an internal mixer". This technical solution points out the problem that "when cleaning the refining chamber of a traditional internal mixer, the interior of the refining chamber is flushed manually by holding a water pipe, which increases the amount of manual labor and makes it difficult to quickly and evenly clean the interior of the refining chamber, affecting the cleaning efficiency and effect of the refining chamber". The utility model provides the following technical solution: "The structure is constructed by sliding a sealing slide cover on the refining chamber to open it, and using an electric push rod to drive the nozzle to descend and extend into the refining chamber. Water is sprayed through the nozzle to the inner wall of the refining chamber. The driving gear is meshed with the transmission gear. The water pipe can be driven to rotate by a motor, so that the water sprayed from the nozzle can flush various areas inside the refining chamber, which is convenient for quickly and evenly cleaning the interior of the refining chamber, and there is no need to manually hold a water pipe to flush the interior of the refining chamber."

[0004] The above solution has the following drawbacks: in actual use, it is difficult to wash off the material attached to the rotor by just spraying water from the nozzle, so a cleaning mechanism of the internal mixer is proposed to solve the above problem. Utility Model Content
