TJGT8 series automatic grease-removing intelligent equipment uses MNB technology to adopt full-section over-flow method, combined with the newly-invented self-cleaning slagging device with bottom separation structure and a wheel-type scraping mechanism to realize slag water separation. The separation of oil and water, the function of wastewater improvement, at the same time, achieve the standard discharge of catering wastewater pretreatment, from functional to functional conversion, can integrate APP, Internet of Things, big data technology, and jointly create upgrade products of smart oil separation. The equipment has small floor space, no odor, no pollution to the environment, low energy consumption, simple maintenance and management, and high economic efficiency. The invention solves a series of problems in the prior products that the acid smell is serious, the scraping and scraping oil is water, the efficiency is low, the sticking is blocked, the mud is more, the flow channel is narrow, and the water is not up to standard.
