The invention relates to the technical field of
sewage treatment, in particular to a building
engineering sewage purification treatment device which comprises a
sewage collecting tank, a garbage collecting tank, a conveying
system and a cleaning
system, and further comprises a
grating arranged in the sewage collecting tank and used for intercepting garbage in sewage; according to the sewage purification treatment device for constructional
engineering, the guide
assembly and the trigger
assembly are arranged, so that the conical rod can be automatically popped up and reset when needed, manual intervention is not needed, the
automation degree of the device is improved, and due to the ingenious design of the driving part, the
synchronizing part, the transmission part, the positioning part, the
extrusion part and other assemblies, automatic popping up and resetting of the conical rod are achieved; in addition, it is ensured that the position of the cone rod after resetting is accurately controlled, faults caused by position deviation are avoided, and the stability and reliability of the cone rod in the popping and resetting process are ensured through mechanical structures such as a driving spring, a transmission gear, a
ratchet wheel and ratchets.
