Description
Technical Field
[0001] The utility model relates to the technical field of pesticide processing equipment, in particular to a segmented rectifying tower. Background Technique
[0002] Pesticides refer to a substance or a mixture of several substances and their preparations that are used to prevent and control diseases, insects, weeds, rodents and other pests harmful to agriculture and forestry, and that are used to purposefully regulate the growth of plants and insects. They are chemically synthesized or derived from organisms or other natural substances. In order to prevent pesticides from polluting the environment, harmful substances in pesticide raw materials need to be separated by a segmented rectifying tower during the production process;
[0003] During the process of segmented rectification of pesticide raw materials, usually the pesticide raw materials to be subjected to segmented rectification are introduced into the interior of the segmented rectifying tower, and then the pesticide raw materials are heated by a heating device. After the pesticide raw materials are heated and evaporated, they form vapors that gradually float upward. The vapors pass through a packing layer. The function of the packing layer is to increase the contact area with the vapors and promote the separation of the mixture. The boiling points of different packing layers are different, so they will be separated according to their different boiling points in the packing layer. Secondly, the vapors are cooled in the packing layer and become liquids. Finally, the separated pure substances are discharged;
[0004] During the heating process of the existing segmented rectifying tower for pesticide raw materials, although a stirring device is driven by a driving device to stir the pesticide raw materials, due to the relatively single stirring direction of the stirring device, the contact area between the pesticide raw materials and the heating device is limited, reducing the evaporation efficiency, and there will also be a situation where the pesticide raw materials sink to the bottom. Some segmented rectifying towers use multiple groups of stirring devices to stir and mix the pesticide raw materials in multiple directions. Although the evaporation efficiency is improved, the cost is relatively high. For this reason, we propose a segmented rectifying tower. Content of the Utility Model

Through the cooperative setting of the stirring fan blades and the vertical plates, the pesticide raw materials can be stirred in multiple directions, further increasing the contact area between the pesticide raw materials and the inner wall of the tower body. The cost is relatively low. The whole process only requires one motor to complete. While accelerating the evaporation speed of the pesticide raw materials, it can also prevent the pesticide raw materials from sinking to the bottom, and can effectively solve the problems in the background technique.

[0030] The working principle of a segmented distillation column provided by the utility model is as follows: Before use, the feed pipe 4, the discharge pipe 3 and the connecting pipe 63 are docked with external pipelines. During operation, the feed valve is opened, and then the pesticide raw materials that need to be segmented and distilled are introduced into the interior of the segmented distillation column through the feed pipe 4. After that, through the regulation of the control switch group 2, the electric heating wire 86 starts to operate, thereby heating the pesticide raw materials. During the heating process of the pesticide raw materials, through the regulation of the control switch group 2, the motor 12 starts to operate.

After the pesticide raw materials are heated and evaporated to form vapor, the vapor gradually floats upward. The vapor passes through the packing layer 62. The packing layer 62 is a framework packing layer, which is composed of many slender, curved and evenly separated metal wires and woven according to certain rules. The framework packing has a large surface area, a compact structure and good mass transfer effect, and is especially suitable for mixtures that are difficult to separate. The function of the packing layer 62 is to increase the contact area with the vapor and promote the separation of the mixture. The boiling points of different packing layers 62 are different, so they will be separated according to the different boiling points in the packing layer 62. Secondly, the vapor is cooled in the packing layer and becomes liquid. Then the connecting valve is opened, and the separated pure substances are finally discharged through the connecting pipe 62.
