Sample filtering mechanism of analyzer

The sample filtering mechanism comprises a cylinder cover, a cylinder body and a drainage pipe, the bottom end of the cylinder cover is in threaded connection with the cylinder body, the drainage pipe is fixed to the bottom end of the cylinder body, and a water inlet pipe is fixed to the top end of the cylinder cover. Through the cooperative design of the multiple layers of treatment pipes, the connecting pipe and the filter cartridge, it is guaranteed that sewage can enter the filter cartridge along the connecting pipe, the filtering completeness of the filter cartridge is guaranteed, classified filtering and collecting are facilitated, subsequent analysis and detection are facilitated, the cartridge cover, the cartridge body, the treatment pipes and the filter cartridge are detachable, a filtering mechanism is convenient to clean or replace, and the practicability is high. The rotating rod is driven by the motor to rotate, and when the rotating rod rotates, the auxiliary shifting rod is driven to scrape imp
