Patent number: 10058958Abstract: A manufacture method of a lining plate structure for use with a tube mill for the cement industry. The manufacture method has the following three technical solutions: 1) metal lining plate, 2) ceramic lining plate, and 3) combined lining plate. The manufacture method includes: lining the concave-convex space, formed in the combination of metal lining plate and tube body, with corundum ceramic lining plate; then installing the combined lining plate on the steel plate of the tube body through inlaying, sticking and local welding. Under the same reference conditions of the present method, the weight of lining plate is reduced 50%, saving the steel material consumption by more than 50%; and the service life of the lining plate for use with the tube mill of cement industry is doubled, up to 15000-20000 hours.Type: GrantFiled: August 31, 2011Date of Patent: August 28, 2018Assignee: HUAZHI ENERGY CONSERVATION (HK) CO., LIMITEDInventor: Xiaoru Li

Patent number: 8584374Abstract: The invention relates to a method for removing water from a mixture containing at least one compound having at least one group reactive towards isocyanate and containing water, the mixture being applied to the surface of a rotating body A, the mixture flowing over the surface of the rotating body A to an outer region of the surface of the rotating body A and water evaporating from the mixture. In particular, this method is suitable for removing water from alcohols and amines.Type: GrantFiled: May 28, 2009Date of Patent: November 19, 2013Assignee: Construction Research & Technology GmbHInventors: Simone Klapdohr, Burkhard Walther, Helmut Mack, Zhizhong Cai, Laurent Marc, Jochen Mezger, Tobias Austermann, Silke Flakus

Patent number: 7998309Abstract: A one step method and system for producing nanofluids by a nanoparticle-source evaporation and deposition of the evaporant into a base fluid. The base fluid such oil or ethylene glycol is placed in a rotating cylindrical drum having an adjustable heater-boat-evaporator and heat exchanger-cooler apparatus. As the drum rotates, a thin liquid layer is formed on the inside surface of the drum. An insulated heater-boat-evaporator having an evaporant material (nanoparticle-source) placed within its boat evaporator is adjustably positioned near a portion of the rotating thin liquid layer, the evaporant material being heated thereby evaporating a portion of the evaporant material and forming nanoparticles, the nanoparticles absorbed by the liquid film to form nanofluid.Type: GrantFiled: March 23, 2010Date of Patent: August 16, 2011Assignee: The United States of America as represented by the United States Department of EnergyInventors: Milivoje Kostic, Mihajlo Golubovic, John Hull, Stephen U. S. Choi

Publication number: 20020008009Abstract: Liquid organic material is controllably delivered to a receptacle located in the center of a heated surface capable of horizontally rotating about its central axis. As the heated surface rotates, material deposited within the central receptacle is forced outwardly and across the rotating surface. As the material moves radially, it evaporates into a vapor which is then transported to one or more nozzles. From the nozzles, the vapor is applied to a substrate and condensed. Relative to existing devices and methods, the present invention enables the evaporation of a wider variety of organic liquids, greater reliability in continuous operation, a decrease in maintenance, and a larger and more constant material flow rate.Type: ApplicationFiled: September 6, 2001Publication date: January 24, 2002Applicant: 3M Innovative Properties CompanyInventors: Charles Daniel Lemme, Marc G.
