Patent number: 11596879Abstract: A filter press includes a frame, a hydraulic system for compressing and releasing filter plates, the filter plates, a filter chamber, a feed pump, a high-pressure clean water pump, a control system, a rotating plate, a cake removal knife, a squeeze disc, a squeeze disc sleeve, a drive shaft, a brake, a left pull rod, a right pull rod, a pull rod disc, a connector and clutches. The filter cake in the entire filter press can be removed without opening the filter plates in sequence. The filter cake washing is carried out in an enclosed room in a normal direction and a reverse direction, which can not only maintain the dryness and cleanness of the working environment, but also can effectively collect, process treat and recycle the washing water, thus achieving the zero discharge of waste water to meet the environmental requirements at a low cost.Type: GrantFiled: August 6, 2020Date of Patent: March 7, 2023Assignee: Shanghai Liqing Equipment Co., Ltd.Inventor: Xinqiang Zhang

Patent number: 11352680Abstract: An apparatus and a method for rapidly heating cold-rolled strip steel (10). The apparatus for rapidly heating cold-rolled strip steel (10) comprises a heating zone, a soaking zone, and a cooling zone, and the heating zone is sequentially divided into a first heating section (1), a second heating section (2), a third heating section (3), and a fourth heating section (4) along a moving direction of the strip steel (10) to be heated, the first heating section (1) and the fourth heating section (4) being radiant heating sections, and the second heating section (2) and the third heating section (3) being inductive heating sections. The method for rapidly heating cold-rolled strip steel (10) uses the apparatus for rapidly heating cold-rolled strip steel (10) to heat the strip steel (10).Type: GrantFiled: May 16, 2018Date of Patent: June 7, 2022Assignee: BAOSHAN IRON & STEEL CO., LTD.Inventors: Huabing Zhang, Guobao Li, Baojun Liu, Dan Han, Xinqiang Zhang, Guanghua Cui, Jianbing Chen, Wen Xiao, Zipeng Zhao

Patent number: 9604312Abstract: A fast-speed laser scoring method is provided, in which a set of related laser scoring device is used to simultaneously score lines on the upper surface and the lower surface of an oriented silicon steel strip, which is being fed and traveling forwards on a production line, with high-focalized continuous wave laser beam; the lines scored on the upper surface and the lines scored on the lower surface have the same space between every two adjacent scored lines but are staggered each other in order to reduce iron loss evenly. The space between every two adjacent scored lines on the same surface is 6-12 mm, laser power is 1000-3000 W and scanning speed is 100-400 m/min. The machining rate of the scoring method and device attains 1.5-2 times the one of conventional scoring methods which can not simultaneously score the upper and lower surfaces of a steel strip at a time. The lines scored on a steel strip by the method can reduce iron loss of the strip by 10-16%.Type: GrantFiled: April 28, 2011Date of Patent: March 28, 2017Assignee: BAOSHAN IRON & STEEL CO., LTD.Inventors: Wangya Huang, Guobao Li, Xinqiang Zhang, Xing Mao, Wanqing Guo, Jianru Zhu, Banglin Xiang
