Problems solved by technology

Some use frequency converters to realize the speed regulation of the cylinder, but this method requires a large motor power and a high-voltage power supply, which is expensive and unstable
At the same time, due to the large volume of the motor reducer required to provide power for the large cylinder mixer, the motor reducer occupies the axial space of the cylinder and the rubber wheels cannot be evenly arranged, resulting in insufficient supporting force of the rubber wheels and premature wear. Therefore, all large-scale cylindrical mixers adopt the structure of metal roller supporting ring gear transmission. This results in serious vibration, and the roller wears quickly and cannot be repaired.

Abstract

The invention discloses a hydraulic motor glue wheel-supported stepless transmission drum mixer. A drum body (1) of the drum mixer is driven by glue wheel driving groups which are radially and symmetrically arranged on one side or two sides of the drum body; a driving main shaft (6) is arranged in the shaft hole of a self-aligning bearing (8) of a first bearing seat and a bracket (9) and providedwith 1 to 3 first glue wheel groups (7); the output shaft of a first hydraulic motor (3) is coupled with the driving main shaft (6) through a coupling (4); a frame (10) is provided with the first bearing seat and the bracket (9); a damping glue cushion (11) is arranged between the base of the frame and the frame (10); and the frame (10) is fixed on a rigid foundation (12). The hydraulic motor glue wheel-supported stepless transmission drum mixer can obviously reduce the vibration caused by the drum body during rotation and impact force caused by feeding and has the advantages of stable operation, low noise, small starting resistance, strong load bearing ability, simple structure, convenient maintenance and the like.

Description

technical field [0001] The invention relates to a primary and secondary cylinder mixer for mixing sintered materials. technical background [0002] Before the mineral powder is sintered, the mixture needs to be mixed through a cylinder mixer for primary and secondary mixing, so that the material temperature, moisture and components of the mixture can be mixed evenly and granulated. Due to the different composition of the mixture, the mixing and granulation is completed in the primary and secondary mixers respectively, so the required speed of the mixer is also different, and the speed needs to be determined with the best mixing effect and the highest output. The rotation of the existing cylinder mixer is driven by the transmission pinion to rotate the large ring gear on the cylinder, or the transmission rubber wheel supporting the cylinder is driven by the motor reducer to rotate the cylinder. changing. Some adopt frequency converter to realize cylinder speed regulation, b...
