3results about How to "Increase vertical height" patented technology

The application relates to a vehicle frame structure in the technical field of vehicle frames, which comprises a longitudinal beam assembly, a mounting seat assembly and a cross beam assembly, the longitudinal beam assembly comprises two longitudinally arranged longitudinal beams, the mounting seat assembly is fixedly connected with the lower flange plates of the longitudinal beams, and the cross beam assembly is fixedly connected with the longitudinal beams and the mounting seat assembly. The mounting seat assembly is fixedly arranged below the longitudinal beams, the vertical height of the vehicle frame structure is increased, the cross beam assembly can be fixedly connected with the longitudinal beams or the mounting seat assembly, the vehicle frame can bear larger impact, bending and torsional loads, has higher bearing capacity and torsional resistance, and the overall strength and stability of the vehicle frame are improved.

This invention discloses a reactor and method for cultivating denitrifying granular sludge. The reactor includes a denitrification stirred tank and an aerobic aeration tank. Pre-granulated seed sludge is added to both the denitrification stirred tank and the aerobic aeration tank. The denitrification stirred tank is equipped with a stirring device and has an inlet on its top side. The bottom of the denitrification stirred tank is connected to the bottom of the aerobic aeration tank via a sludge-water circulation pipe. The bottom of the aerobic aeration tank is connected to a sludge discharge pipe, and the top side has an outlet. An aeration device is located at the bottom of the aerobic aeration tank and is connected to an air pump. An air-lift sludge device is located above the aeration device. The air-lift sludge device includes an air collection hood and an upflow pipe connected to the center of the top of the air collection hood. The top of the upflow pipe is connected to the top of the denitrification stirred tank via an upper sludge-water circulation pipe. The reactor and method for cultivating denitrifying granular sludge of this invention create suitable environmental conditions for the rapid cultivation of denitrifying AGS in a continuous flow process.

A battery cell according to an embodiment of the present application includes an electrode assembly, a can accommodating the electrode assembly, and a first electrode terminal electrically connected to the electrode assembly. The first electrode terminal includes a current collector surface positioned at an inner side of the can, a post portion extending from the current collector surface and penetrating the can, and a terminal face extending from the post portion and positioned at an outer side of the can, wherein, in the post portion, a first hole is formed through the current collector surface, and in the terminal face, a second hole is formed that communicates with the first hole and is smaller than the first hole, the second hole being sealed at a surface of the terminal face.
