Multistage eccentric block dual-drum vibration mill

Abstract

The invention relates to a multistage eccentric block (hereinafter referred to as eccentric block) dual-drum vibration mill, in particular to a vibration mill capable of generating a special inertia shock excitation capability. The vibration mill comprises an upper drum, a lower drum, a connecting plate, a left vibration exciter, a right vibration exciter, a connecting sleeve, a motor, a main vibration spring, a damping spring, a supporting seat and a base plate, wherein the connecting pipe is arranged between the upper drum and the lower drum; the upper part of the upper drum is provided with a feeding hole; the lower drum is provided with a discharge hole; the upper drum is fixedly connected with the lower drum through the connecting plate; a spring upper guide post and a spring lower guide post are arranged between the connecting plate of the upper drum and the lower drum and the supporting seat; the main vibration spring is arranged on the spring upper guide post; the connecting plate of the upper drum and the lower drum is connected with the supporting seat through the main vibration spring; the damping spring is arranged between the supporting seat and the base plate; the supporting seat is supported on the base plate through the damping spring; and the left vibration exciter and the right vibration exciter are respectively arranged between connecting plates of an upper mass body and respectively comprise a first-stage shaft which is a vibration exciter shaft, a bearing block, a bearing and a multistage eccentric block assembly.

Description

technical field [0001] The multi-stage eccentric block double-cylinder vibrating mill of the present invention relates to a multi-stage eccentric block (hereinafter referred to as eccentric block) double-cylinder vibrating mill, which is a vibrating mill 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 vibration source of ordinary vibrating mills generally uses vibration motors or ordinary mechanical partial block vibrators (abbreviated as vibrators). [0003] The vibration motor is used as the excitation source and also has the function of the power source. It is generally used in the single cylinder vibration mill. Due to the large size and heavy weight of the double-barreled vibrating mill, it is inconvenient to support or hang. Usually,...

Problems solved by technology

[0005] In many cases, vibration machinery requires the system to have a wide power spectrum curve and 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-refinement, easy agglomeration, reverse crushing, low efficiency, high energy consumption, etc. during ultrafine and ultrafine pulverization of metal or non-metallic brittle powders, ordinary vibrating mills or other grinding equipment can solve these problems almost powerless
