Abstract
本实用新型属于节能控制技术领域，尤其涉及一种水泥厂循环风机节能控制装置，包括进风管，所述进风管的内侧壁固定连接有电动伸缩杆，所述进风管的内侧壁固定连接有轨道，所述轨道的内侧滑动连接有滑动块，所述进风管内设有推移框。本实用新型当进风量较小时，通过电动伸缩杆带动推移框向右移动，推移框会因为滑动块沿着轨道水平向右移动，当推杆穿过对应的穿孔后，会与堵板一和堵板二接触，并带动堵板一和堵板二转动，这样控风框所通风的面积就会被拉大，这样进去的风量就会加大，再通过电动伸缩杆就可以利用弹簧带动堵板一和堵板二向控风框转动，这样通风面积会被缩小，进风量也就小了，从而完成对风量控制。
This utility model belongs to the field of energy-saving control technology, and particularly relates to an energy-saving control device for a circulating fan in a cement plant. It includes an air inlet pipe, an electric telescopic rod fixedly connected to the inner wall of the air inlet pipe, a track fixedly connected to the inner wall of the air inlet pipe, a sliding block slidably connected to the inner side of the track, and a pushing frame inside the air inlet pipe. When the air intake volume is small, the electric telescopic rod drives the pushing frame to move to the right. The pushing frame moves horizontally to the right along the track due to the sliding block. When the push rod passes through the corresponding perforation, it contacts the first and second blocking plates, causing them to rotate. This increases the ventilation area of the control frame, thus increasing the air intake volume. Then, the electric telescopic rod, using a spring, drives the first and second blocking plates to rotate towards the control frame, reducing the ventilation area and the air intake volume, thereby achieving airflow control.
