摘要
侧梁激振脱水筛是直线振动筛的一种,主要用于煤泥脱水,是选煤厂的重要设备之一。
传统的直线振动脱水筛,一般结构较复杂,机体较笨重,而且能耗高,为此研制了一种新型的脱水筛。侧梁激振脱水筛与其它振动筛相比具有如下结构优点:
(1)单位面积处理量是普通振动筛的2倍以上;
(2)抛射角度合适,抛射强度高,振幅大,单位处理能力的能耗较小,与同面积的筛子相比,成本可降低20%;
(3)电动机与箱式激振器激振轴采用橡胶联轴器(即挠性联接或软联接),可补偿电机轴线与偏心轴轴线不同心造成的误差。
(4)偏心块为轴偏心结构,轴承采用干油润滑,不存在漏油问题;
(5)依靠箱式激振器长短轴上键槽相互位置,使得两偏心块之间成60°,保证激振力始终与水平成60°夹角,使得物料以合适的速度向出料槽前进;
(6)可通过增减副偏心块质量调节筛子振幅,在物料水分和粘度的变化时,仍能保证激振力要求。
本设计论述了振动筛的基本理论,对侧梁激振脱水筛主要的零部件进行了选择、设计和校核计算。对其安装、调试和常见的故障也作了简要的介绍。

Abstract
Lateral excitation beam dehydration screen is a straight line, mainly for dehydration slime, coal preparation plant is one of the key equipment.
The traditional linear vibration sieve dehydration, the general structure of the plex, more cumbersome body, and high energy consumption, for which developed a new type of dehydration sieve. Lateral excitation beam dehydration sieve pared with other structures have the following advantages:
(1) per unit area is the capacity of ordinary shaker of more than two times;
(2) projectile point of view appropriate, projectile high intensity, amplitude, and the unit energy consumption of smaller capacity, pared with the size of the sieve, the cost can be reduced by 20%;
(3) the box-type motor shaft vibration excitation using rubber couplings (that is, flexible connectivity or soft link) that pensate for the electrical axis and the eccentric shaft axis different heart of the error;
(4) eccentric block is the structure of Axis eccentric, by dry-lubricated bearings, and there is no oil spills;
(5) rely on me-length shaft keyway Exciter each other location, making the two blocks between the eccentric into 60 °, always exciting force and guarantee a level of 60 ° angle, making materials to the appropriate speed to the local materials Forward;
(6) can increase or decrease in the quality of eccentric block amplitude adjustment sieve, water and materials in the viscosity of the changes, can guarantee exciting force requirements.
The design o
