Description

Technical Field

[0001] The utility model relates to the technical field of liquid reflux distributors, in particular to a liquid reflux distributor for distillation equipment used in the production of chemical raw materials. Background Art

[0002] During the use of distillation equipment for chemical raw material production, it is necessary to control the purity and output of the top product by adjusting the reflux ratio. The reflux ratio is the ratio of the reflux liquid flow rate to the product flow rate during the distillation process. By adjusting the reflux ratio, the concentration of the distillation product can be controlled while taking into account the consumption of cold and hot energy, thereby achieving higher economic benefits for the distillation process.

[0003] In the prior art, the adjustment of the reflux ratio in distillation equipment is usually achieved through an external reflux ratio distributor. Its working principle is to drive the connecting rod to move up and down through the coupling effect of repeated power-on and power-off of the inner and outer magnets of the solenoid valve, and then convert it into the left and right sliding of the funnel through the hinge connection at the lower end of the connecting rod, thereby controlling the reflux and discharge amounts of the liquid.

[0004] During actual use, it was found that the first problem was that the electromagnet that provides power, when the moving iron moves up and down, the material area and the electromagnet moving cavity cannot be sealed. A small amount of material will enter the moving iron moving cavity along with the connecting rod, causing corrosion and friction damage to the electromagnet, thereby affecting the liquid diversion accuracy.
