Patent number: 11603488Abstract: The present invention relates to a process for preparing a metal-chelate retarder by a sol-gel method. The method comprises the following steps: weighing calcium nitrate tetrahydrate, aluminum nitrate nonahydrate and ferric nitrate nonahydrate according to a certain mass ratio and adding them into deionized water; placing the mixed solution on a magnetic stirrer and stirring the mixed solution evenly; adding citric acid monohydrate or gluconic acid, ethylene glycol or glycerol, and placing the mixed solution into a water bath to react to obtain the metal-chelate retarder. The process of the present invention has a reliable principle, overcomes the defects of long production period, complex preparation and the like of the existing retarders, has the advantages of simple process operation, cheap and easily available raw materials, and short production period.Type: GrantFiled: July 22, 2020Date of Patent: March 14, 2023Assignees: SOUTHWEST PETROLEUM UNIVERSITY, CNPC BOHAI DRILLING ENGINEERING COMPANY LIMITEDInventors: Xiaowei Cheng, Shuxun Zhao, Yang Yu, Zhihui Lin, Gaoyin Zhang, Chaoming Wu, Kaiqiang Liu, Wenming Liu, Zuwei Chen, Jiawen Fu, Tianpeng Zuo, Ben Qi, Chunmei Zhang, Zaoyuan Li, Sheng Huang, Xiaoyang Guo

Patent number: 11109733Abstract: The present disclosure discloses a cleaning robot, including a water tank, a dust box, and a main body. The water tank and the dust box are assembled together to form a water tank dust box assembly. The main body includes an accommodating space adapted to accommodate the water tank dust box assembly. The water tank dust box assembly includes a mistake-proofing device. The mistake-proofing device, when the water tank and the dust box are not assembled to form the water tank dust box assembly, is in an ejected state so that the water tank or the dust box cannot be installed into the accommodating space.Type: GrantFiled: May 22, 2019Date of Patent: September 7, 2021Assignee: GuangDong BONA Robot Co., Ltd.Inventors: Kai Yang, Wenming Liu
