Patent number: 11912623Abstract: A fluidized solidified soil based on gold tailings includes the following raw materials in parts by mass: 75 parts to 80 parts of gold tailings, 5.2 parts to 13 parts of a dispersant solution, and 9 parts to 16 parts of a solidifying material. A preparation method includes the following steps: mixing the gold tailings with the dispersant solution, and then stirring to obtain a suspension slurry of the gold tailings; and adding the solidifying material, and stirring to obtain the fluidized solidified soil. In the present disclosure, the gold tailings are used as a main material, combined with a special dispersant solution and a special solidifying material, and a fluidized solidified soil is prepared with fluidity suitable for pumping and a certain strength after hardening. The fluidized solidified soil prevents the pollution caused by gold tailings landfilling, and can be used as a filling material for various construction projects.Type: GrantFiled: May 12, 2023Date of Patent: February 27, 2024Assignees: WUHAN INSTITUTE OF TECHNOLOGY, The College of Post and Telecommunication of WITInventors: Zunqun Xiao, Caiyun Xu, Fuqi Wang, Jian Lin, Hui Wang, Zhentao Lv, Yanbin Chang, Haitao Liu, Yinlei Shi, Keqi Luo, Minghui Deng, Puyu Li, Yuepeng Zheng

Patent number: 11121394Abstract: The present invention discloses a rechargeable button cell, which includes an anode shell, a cathode shell and a coiled electric core. The anode shell and the cathode shell define a receiving cavity in which the coiled electric core is located. A channel that extends in an axial direction of the rechargeable button cell is provided in the middle of the coiled electric core. An electrically conductive bar that extends on the cathode shell is located in the channel. An anode tab and a cathode tab of the coiled electric core are provided on the same side, which facilitates monitoring the conditions of the two tabs at the same time during the production and preventing the tabs from being damaged, thereby achieving good weldability and improving the assembling efficiency.Type: GrantFiled: June 24, 2020Date of Patent: September 14, 2021Assignee: Fujian Nanping Yanping District Nanfu New Energy Technology Co., LtdInventors: Haitao Chang, Zhiming Zhang, Sheng Su
