AI Technical Summary
Existing distillation systems suffer from problems such as system contamination by impurities, resource waste, product quality degradation, and limited distillation efficiency when processing complex mixtures. In particular, when processing mixtures containing multiple impurities and specific chemical products such as iodinated compounds, the system is severely contaminated and inefficient.
A distillation head was designed, comprising a distillation head body, a connecting tube, and branch tubes. The branch tubes are arranged at different heights to accommodate two distillation systems simultaneously. By switching between the systems, impurity contamination can be avoided, and impurities and pigments can be distilled out through the two systems first, ensuring the purification effect of the product.
This system avoids contamination of the system by impurities, reduces resource waste, and improves distillation efficiency and product quality. In particular, it avoids pigment contamination when processing compounds containing iodine, thus meeting industrial standards.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental equipment technology, specifically to a distillation head. Background Technology
[0002] Distillation is a common separation and purification technique in chemical synthesis and industrial production, especially suitable for separating different components in liquid mixtures. However, existing distillation techniques have some technical problems when handling complex mixtures:
[0003] First, traditional distillation systems typically only accommodate one distillation unit, limiting their flexibility in handling mixtures containing multiple impurities. During distillation, impurities distilled earlier can contaminate the entire system, leading to a decline in the quality of the target fraction collected later. Furthermore, rinsing with large quantities of the target fraction may be necessary to remove impurities, increasing production costs and wasting resources. Second, certain chemical products, such as iodinated compounds, may undergo deiodination reactions during high-temperature distillation, producing brownish-black pigments that rapidly contaminate the entire distillation system. This not only affects the product's appearance but may also degrade its performance, failing to meet industrial standards. Finally, the distillation efficiency and separation effect of existing systems are often limited by the design of the distillation head. The length and structure of the distillation head directly affect the separation efficiency and purification level of components in the mixture. Shorter distillation heads may fail to effectively separate components with similar boiling points, resulting in poor purification. These problems severely impact the efficiency of the distillation process and product quality, necessitating a new distillation system and its matching distillation head to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a distillation head to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following solution:
[0006] This utility model provides a distillation head, including a distillation head body, a connecting pipe, and a distillation head branch pipe. At least two distillation head branch pipes are provided, which are connected to the distillation head body through corresponding connecting pipes and are arranged at different heights on both sides of the outer wall of the distillation head body.
[0007] In one feasible implementation, the distillation head body is hollow inside and open at both the top and bottom, with both openings being frosted.
[0008] In one feasible implementation, the upper opening of the distillation head body is an inner frosted port, and the lower opening of the distillation head body is an outer frosted port.
[0009] In one feasible implementation, the sidewall of the distillation head body is connected to a first connecting pipe and a second connecting pipe.
[0010] In one feasible implementation, the first connecting pipe and the second connecting pipe are inclined downwards in a direction away from the distillation head body.
[0011] In one feasible implementation, the height of the first connecting pipe is higher than the height of the second connecting pipe.
[0012] In one feasible implementation, the distillation head branch pipe is L-shaped with an obtuse angle, and the connecting pipe connects the vertical section of the distillation head body and the distillation head branch pipe. The ports of the horizontal sections of the two distillation head branch pipes face opposite directions and are both away from the distillation head body.
[0013] In one feasible implementation, a high-vacuum valve is provided at the port of the vertical section of the distillation head branch.
[0014] In one feasible implementation, the high vacuum valve is a PTFE-protected high vacuum valve.
[0015] In one feasible implementation, the horizontal section of the distillation head branch pipe is provided with a ground joint.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] (1) This utility model provides a distillation head that can be equipped with two distillation systems at the same time. After the impurities in the early stage are distilled out, the other distillation system can be switched to collect the target fraction, so as to avoid the impurities distilled out in the early stage from contaminating the distillation system and requiring a large amount of target fraction to rinse the distillation system, resulting in product waste.
[0018] (2) The distillation head provided by this utility model uses two distillation systems to first distill out pigments and impurities, which can avoid the problem of pigments contaminating the entire distillation system during the distillation purification of pigmented products, and thus obtain qualified products.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0023] Example 1
[0024] See Figure 1 This utility model provides a distillation head. The distillation head body 1 is hollow inside and open at both the top and bottom. Both openings of the distillation head body 1 are frosted, ensuring the seal between the distillation head body 1 and other connecting components and preventing leakage of volatile substances during distillation. The upper opening of the distillation head body 1 is an inner frosted opening, and the lower opening is an outer frosted opening. A connecting pipe 2 is connected to the side wall of the distillation head body 1. The connecting pipe 2 includes a first connecting pipe 21 and a second connecting pipe 22. The first connecting pipe 21 and the second connecting pipe 22 are inclined downwards away from the distillation head body 1, and the height of the first connecting pipe 21 is higher than the height of the second connecting pipe 22. Two distillation head branch pipes 3 are respectively connected to the distillation head body 1 through corresponding connecting pipes 2 and are staggered on both sides of the outer wall of the distillation head body 1. The distillation head branch pipe 3 is L-shaped with an obtuse angle. The connecting pipe connects the distillation head body and the vertical section of the distillation head branch pipe 3. The port of the vertical section of the distillation head branch pipe 3 is equipped with a high-vacuum valve 31 protected by PTFE to adjust the internal pressure of the distillation system to meet different distillation requirements. The ports of the horizontal sections of the two distillation head branch pipes 3 face opposite directions and are both away from the distillation head body. The ports of the horizontal sections of the distillation head branch pipes 3 are ground glass joints 32.
[0025] This invention relates to a distillation head with two branch pipes that can simultaneously support two distillation systems. After impurities are distilled off initially, the system can be switched to another distillation system to collect the target fraction. This avoids contamination of the distillation system by impurities from the initial distillation, preventing the need for large amounts of target fraction to flush the system and thus avoiding product waste. Furthermore, the distillation head provided by this invention, through two distillation systems, first distills off pigments and impurities, avoiding the problem of pigment contamination during the distillation and purification of pigmented products, thereby obtaining a qualified product.
[0026] Meanwhile, during distillation, substances with different boiling points gradually evaporate as the temperature rises, and the side arms of the distillation head at different heights can collect components with different boiling points. The increased length of the distillation head also enhances the product separation and purification effect.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
