Publication number: 20240076261Abstract: The present invention discloses a method for preparing an ibuprofen spherical crystal having high bulk density and a product thereof. The method includes: (1) heating ibuprofen until a molten liquid state is reached; and (2) pressurizing the molten liquid state of ibuprofen, dropping the molten liquid state of ibuprofen into a crystallizer filled with water through a liquid distributor for crystallization under stirring conditions until the molten liquid state of ibuprofen is completely dropped, lowering the rotation speed of stirring to allow crystal growing, and finally, subjecting a resulting crystal slurry to post-treatment to obtain the ibuprofen spherical crystal having high bulk density. The ibuprofen spherical crystal has a bulk density of 0.50-0.70 g/mL, a tap density of 0.63-0.89 g/mL, a median particle size of 300-1,000 ?m and an angle of repose of 22-29°.Type: ApplicationFiled: March 24, 2022Publication date: March 7, 2024Inventors: JINLONG LIU, SHUMIN LV, RUIJUN HU, XUEZHONG HE, MENGLIANG DU, XIAOCHUN WANG, ZIYU WANG, LANYING LIANG

Publication number: 20240014471Abstract: A battery housing includes a first housing and a second housing. An accommodating space with an opening is defined by a bottom plate, two first side plates and two second side plates of the first housing. The second housing includes a body, and two first extending plates and two second extending plates arranged on a peripheral edge of the body. An avoiding region is formed on one second side plate. In a first direction, a width of the second extending plate corresponding to the second side plate provided with the avoiding region is smaller than or equal to a width of the avoiding region, and additionally, a width of the two first extending plates is greater than a width of the second extending plate. The second housing covers the opening of the first housing, and the two first extending plates and the two first side plates are fixedly connected.Type: ApplicationFiled: September 22, 2023Publication date: January 11, 2024Inventors: Guosheng TANG, Liwei LIANG, Shumin HU, Jian ZHANG, Jinzhong OUYANG

Patent number: 10556219Abstract: A continuous chemical reactor may include a primary reaction unit and at least one secondary reaction unit. The primary reaction unit has a stirring device and a first temperature regulating device, and a feed inlet provided at an upper portion thereof. The secondary reaction unit is sleeved outside the primary reaction unit, and a reaction chamber is formed therebetween. By adding reaction materials to the primary reaction unit via the feed inlet and adjusting the temperature of the reaction materials by the first temperature regulating device, the reacted materials enter the reaction chamber, and the heat generated in the reaction chamber can be used to adjust the temperature of the materials in the primary reaction unit to more effectively use the heat, and the product after reaction can be discharged from a discharge hole at the lower end of the secondary reaction unit, thereby achieving continuous production.Type: GrantFiled: October 30, 2017Date of Patent: February 11, 2020Inventors: Jianmin Hu, Peikun Wan, Jinzhe Hu, Yuntao Bai, Xiaoyong Liu, Shumin Hu
