Automatic water retaining device for coal preparation plant
The automatic water retaining device for the coal preparation plant comprises a water retaining panel arranged in a ground groove, a driving device used for driving the water retaining panel to move back and forth in the vertical direction of the groove is arranged at the bottom of the water retaining panel, and a liquid level monitoring device used for starting and stopping the driving device is arranged on the ground. The liquid level monitoring device comprises a first electric connection signal source arranged on the ground on the side close to the water retaining panel and a second electric connection signal source arranged in the plant pump pit, and the vertical height of the first electric connection signal source is larger than that of the second electric connection signal source. When overflow is detected, the automatic lifting water retaining panel blocks water in the plant, the water in the plant is prevented from overflowing out of the plant, drainage is treated in time, the negative influence of accidents is reduced, the structure is simple, and operation is safe.
本发明公开了一种选煤厂用自动挡水装置，包括设置在地面凹槽内的挡水面板，所述挡水面板的底部设有用于驱动挡水面板沿凹槽竖直方向来回移动的驱动装置，地面上设有用于启闭驱动装置的液位监测装置，所述液位监测装置包括设置在近挡水面板一侧地面上的电接信号源一和设置在厂房泵坑内的电接信号源二，所述电接信号源一的竖直高度高于电接信号源二的竖直高度。本发明检测到溢水自动升降挡水面板将水阻挡在厂房内，防止厂房内的水溢流到厂房外，及时治理排水，降低事故负面影响，结构简单，操作安全。
