Multistage eccentric block single barrel vibrating mill

Abstract

The invention provides a multistage eccentric block single barrel vibrating mill which relates to a vibrating motor driven vibrating mill capable of generating special inertia excitation capability, and belongs to the technical field of vibration utilization engineering. The vibrating mill comprises a milling barrel, an upper plastid, a lower plastid, a vibrating motor, a main vibrating spring, adamping spring and a bottom plate, wherein the milling barrel is arranged on the upper plastid; the upper plastid is connected with the lower plastid by the main vibrating spring and spring guide columns of the upper plastid and the lower plastid; the lower plastid is supported on a base thorough the damping spring; the vibrating motor is inversely arranged on a support plate of the upper plastid; the vibrating motor comprises a stator, a rotor and multistage eccentric block assemblies; the stator consists of a stator core, a stator winding, a bearing base and a machine casing; the rotor consists of a rotor shaft, a rotor core and a rotor winding; the multistage eccentric block assemblies are respectively arranged at both ends of the rotor shaft; and the multistage eccentric block assemblies are arranged at the left end and the right end of the rotor shaft, and respectively comprise a main eccentric block, an auxiliary eccentric block, a multistage eccentric block, a multistage eccentric block shaft and a multistage bearing.

Description

technical field [0001] The invention relates to a multi-stage eccentric block single-cylinder vibrating mill, which relates to a vibrating mill driven by a vibrating motor capable of producing special inertial vibration, and belongs to the technical field of vibration utilization engineering. Background technique [0002] Vibrating mill is a vibrating mechanical equipment that uses the principle of vibration to complete material grinding operations. The excitation source of ordinary vibrating mills generally adopts ordinary vibration motors or vibrator plus ordinary motors. [0003] Ordinary vibration motor is used as the excitation source and has the function of power source at the same time. It is based on the ordinary motor and is equipped with two sets of eccentric blocks (referred to as eccentric blocks) at both ends of the rotor shaft. Each set of eccentric blocks is divided into two groups. The main and auxiliary partial blocks are usually fan-shaped, and the partial ...

Problems solved by technology

[0006] In many cases, vibration machinery requires the system to have a wide power spectrum curve or certain irregularities in motion trajectory to complete some special operations, such as vibration mills or other grinding equipment for powders, especially superhard, hard Problems such as non-refining, easy agglomeration, reverse crushing, low efficiency, high energy consumption, etc. during ultra-fine and ultra-fine grinding of metal or non-metallic brittle powders, ordinary vibrating mills or other grinding equipment can solve these problems almost powerless
