A fastening and sealing device and assembly and disassembly method for a high-temperature ball mill tank

Abstract

The invention relates to a fastening and sealing device for a high-temperature ball mill tank and an assembly and disassembly method. It has a ball mill cylinder with one end open and an end cover fixedly connected to the open end of the ball mill cylinder through bolt sealing. The end is connected with an exhaust pipe for extracting the vacuum in the ball mill cylinder, and a lock clamp mechanism is provided between the ball mill cylinder body and the end cover. The clip hasp and the lock angle seat are fixed on the end cover. One end of the lock clip hasp is connected with the lock clip closing rod, and the other end of the lock clip hasp is turned over and folded on the lock angle seat. The present invention adopts the combination of bolts and locking mechanism before ball milling, which ensures the requirements of the ball mill cylinder for vacuum degree during vacuuming, and then removes the bolts for locking, and only retains the locking mechanism for locking during high-temperature ball milling, realizing The function of quick disassembly of the end cover of the ball mill tank at high temperature after operation is realized, which further meets the operation requirements of special materials.

Description

technical field [0001] The invention relates to the technical field of roller milling, in particular to a high-temperature ball milling pot fastening and sealing device and an assembly and disassembly method. Background technique [0002] In the current scientific research and material processing and production, roller ball milling devices are commonly used. With the increase in demand for special materials and production processes, the technical requirements for roller ball mills are also getting higher and higher. Roller ball mills used at room temperature usually use conventional bolt and nut fastening devices. But, under the situation of high-temperature ball milling, this device is easy to take place the phenomenon that bolt locks up and can't open tank lid. Once the fastening bolts are locked, it is difficult to take out the materials in the ball mill cylinder, which leads to the interruption of scientific research or production. [0003] In the general galvanizing ...
