Description

Technical Field

[0001] This utility model relates to the field of distillation head technology, and in particular to a glass distillation head. Background Technology

[0002] The distillation head is a key component of the distillation apparatus, primarily used to adjust the reflux ratio during the distillation process, promoting effective contact between the gas and liquid phases to achieve the separation and purification of components in the mixture. The distillation tube is the pipe in the distillation head used to pour out the distillate; one end of its bottom is connected to a collection bottle, through which the distillate is collected. During the collection process, if the distillation product is not sealed in time, especially for low-boiling-point, volatile organic compounds, the product can rapidly evaporate due to the short period of exposure at the bottle opening, resulting in yield loss, or become contaminated by air and dust, affecting the final purity.

[0003] Therefore, it is necessary to provide a new glass distillation head to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a new glass distillation head.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 7 This utility model provides a glass distillation head, which includes: a distillation tube 1, a collection bottle 2 connected to the bottom of the distillation tube 1, a conical tube 12 fixedly installed at the end of the distillation tube 1 and communicating therewith, an inner tube 21 inserted at the opening of the collection bottle 2, and the end of the inner tube 21 located outside the collection bottle 2 abutting against the end wall of the collection bottle 2, a guide port 211 opened in the inner tube 21, a bracket 22 fixedly installed at the bottom of the inner tube 21, and a fixed plate 23 extending into the guide port 211 fixedly installed at the upper end of the bracket 22, an annular sealing plate 24 slidably connected inside the guide port 211 and fitting against its inner wall, and a sealing gasket 231 abutting against the inner bottom wall of the annular sealing plate 24 fixedly installed on the bottom wall of the fixed plate 23; and an ejection structure 4 installed on the bracket 22 to control the abutment between the annular sealing plate 24 and the fixed plate 23.

[0027] It should be noted that: the distillation tube 1 in this utility model is a glass tube in the distillation head used to guide the distilled liquid after distillation to the collection bottle 2. After the collection bottle 2 is connected to the distillation tube 1, the tapered tube 12 will push the annular sealing plate 24 in the guide port 211 downward, so that the annular sealing plate 24 and the fixed plate 23 are relatively far apart, forming a large gap between them for the distilled liquid to pass through. The distilled liquid enters the collection bottle 2 through the gap between the annular sealing plate 24 and the fixed plate 23 via the tapered tube 12 at the end of the distillation tube 1. The collection bottle 2 collects the distilled liquid. After the collection bottle 2 is removed, the ejector structure 4 will close the annular sealing plate 211. Plate 24 is ejected, that is, the annular sealing plate 24 is pushed upward, so that the annular sealing plate 24 abuts against the fixed plate 23, sealing the guide port 211, that is, sealing the mouth of the collection bottle 2, preventing the distillate from escaping. The sealing gasket 231 ensures the sealing effect between the annular sealing plate 24 and the fixed plate 23. In this utility model, the moment the collection bottle 2 is removed, the ejection structure 4 immediately drives the annular sealing plate 24 to slide upward and abut against the fixed plate 23 to seal the mouth of the collection bottle 2, minimizing the exposure time of the product in the air, preventing air and dust from entering the bottle and contaminating the product, and ensuring the distillation quality of the distillate.

[0028] It is worth noting that distillation tube 1 needs to be equipped with a corresponding valve to close it when necessary.

[0029] In this design, annular plates 11 are fixedly installed at the ends of the distillation tube 1 and the collection bottle 2 that are close to each other, and U-shaped clamping plates 5 are snapped onto the two annular plates 11. When the collection bottle 2 is connected to the distillation tube 1, the U-shaped clamping plates 5 are used to clamp the two annular plates 11, thereby connecting the collection bottle 2 and the distillation tube 1. There is no need for complicated operations such as clamping the traditional distillation head. The two annular plates 11 only need to be aligned and pushed into the U-shaped clamping plates 5 laterally to complete the fixation. The collection bottle 2 can be quickly removed by pulling out the U-shaped clamping plates 5. The operation is simple.

[0030] To ensure precise docking between the collection bottle 2 and the distillation tube 1, positioning blocks and corresponding positioning grooves can be fixed on the annular plates 11 on the collection bottle 2 and the distillation tube 1 respectively, so as to ensure that the conical tube 12 is accurately inserted into the guide port 211.

[0031] Furthermore, both annular pieces 11 are fitted with sealing sleeves 3, and the sealing sleeves 3 on the collection bottle 2 are fixedly connected to the inner tube 21; the sealing sleeves 3 wrap around the annular pieces 11 and have a certain elasticity. When the U-shaped card plate 5 is clamped on the two annular pieces 11, the sealing sleeves 3 can improve the stability of the connection between the two.

[0032] Furthermore, the U-shaped notch of the U-shaped card plate 5 is chamfered, and strip grooves 51 are provided on the outer side walls of both the upper and lower sides of the U-shaped card plate 5; the chamfer facilitates the insertion of the U-shaped card plate 5, and the strip grooves 51 facilitate its removal from the annular piece 11.

[0033] The tapered tube 12 is fixedly equipped with an anti-collision rubber pad 13 to protect the end of the tapered tube 12 and prevent the tapered tube 12 from being damaged by direct contact with the annular sealing plate 24.

[0034] It is worth noting that the fixed plate 23 has a hemispherical structure, and the spherical surface of the fixed plate 23 faces upward. When the distillate enters the collection bottle 2, it will pass through the fixed plate 23 which is already located inside the conical tube 12. The lower plane of the hemispherical fixed plate 23 is convenient for sealing, and the upper end of the hemispherical fixed plate 23 can prevent the distillate from remaining.

[0035] The outer diameter of the tapered tube 12 is smaller than the inner diameter of the guide port 211. The tapered tube 12 can abut against the annular sealing plate 24 inside the guide port 211 while smoothly entering the guide port 211 without colliding with the inner wall of the guide port 211 and being damaged.

[0036] It is worth noting that when it is necessary to take out the distillate accumulated in the collection bottle 2, the inner tube 21 can be removed from the bottle mouth of the collection bottle 2. A discharge pipe communicating with its interior can also be installed on the collection bottle 2, and a valve can be installed on the discharge pipe. The discharge pipe can be used to take out the distillate accumulated inside the collection bottle 2 without removing the inner tube 21.

[0037] It is also worth noting that the various components in this utility model are made of different suitable materials according to actual needs.

[0038] In the embodiments of this utility model, please refer to Figure 4 , Figure 5 and Figure 6 The bottom of the annular sealing plate 24 is fixedly installed with a plurality of ejector structures 4 distributed in an annular pattern. The ejector structure 4 includes a sleeve 41 fixedly installed at the bottom of the annular sealing plate 24, a fixing rod 42 fixedly installed on the bracket 22, and the upper end of the fixing rod 42 is inserted into the sleeve 41 and slidably connected thereto. A spring 43 is fixedly installed at the top inside the sleeve 41, and the lower end of the spring 43 abuts against the upper end of the fixing rod 42.

[0039] It should be noted that the spring 43 is always in a compressed state. When the annular sealing plate 24 is squeezed by the conical tube 12, the sleeve 41 moves down, and the fixing rod 42 will further compress the spring 43. When the conical tube 12 moves out of the guide port 211, the elastic force of the spring 43 will cause the annular sealing plate 24 to abut against the fixed plate 23, sealing the mouth of the collection bottle 2, thus realizing the automatic opening and closing of the collection bottle 2.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
