The improvement of the lubricating system of the reducer solves the problem of high failure rate of the reducer of the horizontal rotation extractor; the safety and stability of the transmission system of the horizontal rotation extractor are improved by installing the rotor balance and limit device. The speed of the fixed-bottom flat-rotating extractor is relatively slow, and there are few rotating parts, so the relative failure rate is also low. Most of the main failures occur in the transmission system. The most direct consequence of the failure of the transmission system is to cause the rotor of the extractor to stop. The extractor is the key equipment in the whole technological process. Most of the rotors need to be shut down for a long time for emergency repair, and there is a certain danger in the maintenance and treatment, and the economic loss caused by the shutdown is also very large. Therefore, to evaluate the performance and quality of an extractor, the design and manufacture of the transmission system has become a key link. The transmission system of the extractor was rebuilt as a whole. After a long period of use after the transformation, the extractor operated smoothly, and no downtime was caused by the failure of the transmission system.
The following is a detailed introduction to the specific method of transformation. The transformation of the rotor chain of the pan extractor The transmission mode of the pan extractor is: an adjustable speed motor double-stage cycloidal pin gear reducer transmission box, and the driven wheel drives the transmission chain on the side wall of the rotor or the rack rotor to rotate.
The extractor rotor we use is equipped with a transmission chain. During use, there have been cases where the pins have escaped and fallen off, and the chain has been bitten by gears. Due to the unreasonable installation form of the rotor chain, it is difficult and time-consuming to disassemble the rotor chain. In the rush repair, the shell of the extractor needs to be opened. To remove the damaged rotor chain, the pins on the chain must be knocked off first. Because a large amount of solvent gas escapes during the disassembly process, it is very dangerous to hit the metal violently even with explosion-proof tools, and the long working time is also very harmful to the health of the workers.
In view of these situations, we have made great improvements to the installation form of the rotor chain. Change the installation form of the upper and lower pressure plates and interlocking to segmental connection and hook fixing. Divide the rotor chain into sections every 9 sections, and fix the two ends of each section on the trapezoidal plate with large bolts. There are 3 sets of hooks in each section, and the upper and lower ends of the column pins of the rotor chain lie in the hook grooves of the hooks. When a section of the rotor chain is damaged, as long as the fixing bolts at both ends of the section of the chain where it is located are removed, the section of the chain can be easily removed for repair and replacement.
