Abstract

The present invention relates to the field of dehydration treatment technology, and in particular to a high-efficiency evaporation and concentration tower. In the current evaporation and concentration tower, the contact area between the container and the solution is small, the heat transfer efficiency is low, and the natural falling speed of the solution vapor after condensation is slow, which leads to the disadvantage of low evaporation and concentration efficiency of the solution. A high-efficiency evaporation and concentration tower includes a base; a box body is fixedly connected to the base, a liquid inlet is opened on the top of the box body, and a feed pipe is fixedly connected to one side of the box body, and the feed pipe is connected to the box body. The servo motor drives the multi-stage evaporation rack and the solution on the multi-stage evaporation rack to vibrate, increase the contact area between the multi-stage evaporation rack and the solution, and enhance the heat transfer efficiency. The diverter plate will swing and divert the solution falling on the multi-stage evaporation rack, so that the solution flows more evenly on the multi-stage evaporation rack, which can increase the contact area between the multi-stage evaporation rack and the solution, enhance the heat transfer efficiency, and thus improve the evaporation and concentration efficiency of the solution.

[0036] Initially, a proper amount of coolant is injected into the cavity between the isolation plate 6 and the upper part of the inner wall of the box body 2.

[0040] Example 3

[0041] On the basis of Example 1, Figure 9-Figure 16As shown, an intermittent toggle mechanism is also included, and the intermittent toggle mechanism is arranged on the multi-stage evaporation frame 73. The intermittent toggle mechanism includes an inclined rod 111, and the inclined rod 111 is welded on the mounting frame 86.

When the movable frame 83 drives the mounting frame 86 to move back and forth, the mounting frame 86 will drive the inclined rod 111 to move in the direction close to the toggle frame 114, and the inclined rod 111 will contact one of the extrusion inclined surfaces on the inclined rotating ring 115. The movement of the inclined rod 111 will push the inclined rotating ring 115 and the positioning block 117 to move in the direction close to the toggle frame 114, and the return spring 116 will be compressed. One end of the positioning rod 118 is no longer located in one of the positioning grooves on the positioning block 117. As the inclined rod 111 continues to move, the inclined rod 111 will push the inclined rotating ring 115 to rotate clockwise. The clockwise rotation of the inclined rotating ring 115 will drive the positioning block 117, the return spring 116, the toggle frame 114 and the limiting shaft 113 to move. By rotating clockwise, the toggle frame 114 will toggle the solution on the multi-stage evaporation frame 73 upward.

The reset of the return spring 116 will drive the inclined rotating ring 115 and the positioning block 117 to move and reset in a direction away from the toggle frame 114. The positioning block 117 will contact the reset inclined surface on the positioning rod 118, and the positioning rod 118 will squeeze the positioning block 117, the return spring 116, the toggle frame 114 and the limit shaft 113 to rotate counterclockwise by a certain angle, and reciprocate in sequence.
