Publication number: 20180155626Abstract: The present invention discloses a substance vehicle of pyrolysis reactor to apply for loading the substances of pyrolysis reactor. The substance vehicle includes a vehicle body, at least two movable doors and at least two fixed units. The vehicle body is used to accommodate the pyrolysis substances, and the movable door is movably disposed at the bottom of the vehicle body. When the fixed units are changed from the first position to the second position, a part of the fixed unit will disengage from the bottom of the movable door, such that the movable doors are opened by gravity and the pyrolysis substances are dropped.Type: ApplicationFiled: February 1, 2018Publication date: June 7, 2018Inventor: Li-Feng Cheng

Patent number: 9399737Abstract: An insulating and cooling cracking device includes a thermal cracking furnace accommodated therein. The insulating and cooling device has at least one cooling opening set on its side wall and at least one adiabatic cover. When the thermal cracking device is in heating, the adiabatic cover is closed. When the pyrolysis process is completed, the adiabatic cover is opened to allow the air to flow into one cooling opening. The air further flows through the surface of the thermal cracking furnace, and flows out from another cooling opening to achieve the advantage of more rapid cooling.Type: GrantFiled: June 4, 2013Date of Patent: July 26, 2016Assignee: E-SUNSCIENCE CO., LTD.Inventors: Li-Feng Cheng, Hsien-Cheng Yu

Patent number: 8910892Abstract: A waste tire separation recycling treatment device includes a machine rack, a pair of crushing rollers, a pair of stripping wheels and a guiding portion. After a waste tire, which is performed with pyrolysis, is placed in the device to obtain a non-metal scrap, a metal scrap and a mixture, and above 98% of the non-metal scrap, the metal scrap and the mixture are sequentially rolled and striped off to transform them into the non-metal scrap and the metal scrap. Afterward, several separation processes are performed to separate the non-metal scrap and the metal scrap, thereby greatly increasing the efficiency of separation recycling treatment.Type: GrantFiled: January 7, 2013Date of Patent: December 16, 2014Assignee: E-Sunscience Co., Ltd.Inventor: Li-Feng Cheng

Publication number: 20110247534Abstract: A waste recycling apparatus includes a temporary storage tank, a pyrolyzing furnace, a first blower, a material storage tank, a second blower, and a rotary valve and a magnetic device. The temporary storage tank carries a waste. The pyrolyzing furnace decomposes the waste into a non-iron material and an iron material. The first blower produces winds to blow the waste into the pyrolyzing furnace. The material storage tank stores the non-iron material and the iron material and includes an outlet. The second blower produces winds to blow the non-iron material and the iron material into the material storage tank. The rotary valve controls a discharge quantity of the non-iron material and the iron material. The magnetic device is installed on a side of the outlet, and the magnetic device attracts the iron material to separate the non-iron material and the iron material. The waste recycling apparatus can recycle wastes automatically.Type: ApplicationFiled: April 8, 2010Publication date: October 13, 2011Applicant: E-SUNSCIENCE CO., LTD.Inventor: LI-FENG CHENG

Patent number: 5853131Abstract: A desktop paper shredder including a housing in which a pair of shafts are rotationally mounted. The housing is provided with an entrance that corresponds to and is aligned with the shafts. A paper trash container is removably disposed at the lower portion of the housing. The shafts are driven by a driving device and meshed with each other such that their rotations are opposite to each other. Each shaft is further provided with a spiral groove in which a plurality of sets of shredding blades are disposed therein. Each of the sets of shredding blades is spaced from the next set of shredding blades by a spacing collar on which is provided a paper trash stopper. The external end portion of each paper trash stopper is fixedly attached to the configuring tab within the housing. The perimeter of each shredding blade is further provided with a plurality of knives. Each shredding blade is further provided with a projecting tab that rests in a selected spiral groove.Type: GrantFiled: November 10, 1997Date of Patent: December 29, 1998Inventor: Li-Feng Cheng
