Description

Technical Field

[0001] The utility model relates to the technical field of distillation recovery, in particular to a distillation recovery control device. Background Art

[0002] In the prior art, fine chemical distillation and purification are mainly based on intermittent distillation. The distillation process needs to adjust the recovery and flowback ratio many times. As the amount of material and composition in the kettle change during the distillation process, the evaporation amount continues to change. The ratio is adjusted manually according to the flow rate. At this time, the operator needs to make adjustments continuously, but the efficiency of manual adjustment may not be high. At the same time, the content of the recovered material in intermittent distillation is unstable, and it is difficult to adjust. It is not easy to control the quality of the distillation recovery components. Utility Model Content

[0039] The gas supply pipe 401 is connected to an external gas supply pump for delivering gas to the piston cylinder 4. The external gas pump is provided with a commercially available electromagnetic control valve, and the gas supply and gas stop time can be controlled by a pre-set program of the electromagnetic control valve.

[0040] A partition plate 101 is fixedly connected to the distribution hopper 1 , and the partition plate 101 is located directly below the distribution head 7 .

[0043] Reference Figure 1-Figure 3During use, the liquid is transported to the distribution hopper 1 through the feed pipe 3. During the process of transporting the liquid, gas can be transported to the piston cylinder 4 through the gas pipe 401. The transported gas will enter the bottom cavity of the piston cylinder 4. The gas entering the piston cylinder 4 will push the slide plug 403 to move upward. The upward movement of the slide plug 403 will pull the piston connecting rod 402 to move upward. The upward movement of the piston connecting rod 402 will pull the connecting rod 701. At this time, the distribution head 7 will rotate around the second pin 9. At this time, the liquid transported through the feed pipe 3 will be sprinkled through the distribution head 7 tilted to the left. On the left side of the partition 101, and discharged through the first discharge pipe 5; after supplying gas for a period of time, stop supplying gas to the piston cylinder 4, at this time, under the action of the restoring elastic force of the spring 404, the sliding plug 403 will reset downward, and the downward movement of the sliding plug 403 will push the piston connecting rod 402 to move downward, and then push the distribution head 7 to rotate and reset, when the sliding plug 403 moves down to the maximum thread, the distribution head 7 rotates toward the right side of the partition 101, at this time, the material liquid transported by the feed pipe 3 will be sprayed on the right side of the partition 101 through the distribution head 7 tilted to the right, and discharged through the second discharge pipe 6.

[0044] The up and down reciprocating motion of the sliding plug 403 in the piston cylinder 4 arranged in the device drives the distribution head 7 to swing left and right, thereby effectively adjusting and distributing the transported liquid. There is no need to manually adjust the distribution ratio, thereby improving the distribution efficiency. By controlling the time of gas input through the gas pipe 401, the content of the distributed liquid can be controlled, thereby further improving the distribution efficiency.
