Description

Technical Field

[0001] This utility model relates to the field of distillation apparatus technology, specifically a distillation apparatus for chemical reagent testing. Background Technology

[0002] In the testing of chemical reagents, distillation can be used to purify and separate impurities from the reagents. Distillation takes advantage of the different boiling points of the components in a liquid mixture. By heating the liquid to evaporate it, and then condensing the vapor back into liquid, the impurities can be separated.

[0003] In the prior art, such as the chemical experimental distillation apparatus proposed in patent application number "CN201910819863.4", a condenser tube, an inlet water pipe, and an outlet water pipe are included. A spiral tube is glued inside the condenser tube. By setting up the condenser tube, the inlet water pipe, the outlet water pipe, and the spiral tube, the high-temperature gas and the condensate have a larger contact area and contact time, which can improve the condensation efficiency of the apparatus.

[0004] However, in the aforementioned patent application, heat exchange between a spiral tube and a condenser tube is used to achieve the condensation of high-temperature gas. However, both the spiral tube and the condenser tube are set at an angle, and there is a height difference between each turn of the spiral tube. This causes the generated vapor to remain inside the spiral tube after condensation, and the liquid droplets obtained from condensation cannot be fully recovered. Utility Model Content

[0005] The purpose of this invention is to provide a distillation apparatus for chemical testing, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A distillation apparatus for chemical testing includes a distillation flask and a condenser. The distillation flask is used to contain chemicals. A steam delivery pipe is fixedly connected to the mouth of the distillation flask. The condenser is equipped with a multi-component flow mechanism. The flow mechanism includes a spiral-designed flow divider condenser with an inlet and an outlet at both ends.

[0008] The top and bottom of the condensation chamber are respectively provided with a first communicating vessel and a second communicating vessel. The top of the inlet pipe penetrates through the top of the condensation chamber and is fixedly installed with the bottom of the first communicating vessel. The bottom of the outlet pipe penetrates through the bottom of the condensation chamber and is fixedly installed with the second communicating vessel. One end of the steam conveying pipe is fixedly installed with the pipe opening at the top of the first communicating vessel.

[0009] Preferably, the top and bottom of the condensation chamber are fixedly connected to a condensate inlet pipe and a condensate outlet pipe, respectively, and both sides of the condensation chamber are fixedly connected to a concave positioning frame.

[0010] Preferably, a sample collection container is provided at the bottom of the second communicating vessel, and a support base is provided at the bottom of the sample collection container.

[0011] Preferably, a fixing rod is fixedly connected to the top of the support base, and a U-shaped support rod is fixedly connected to the fixing rod. Both ends of the U-shaped support rod pass through the concave positioning frame. The concave positioning frame is provided with fixing bolts, which pass through the U-shaped support rod and are threadedly connected to the concave positioning frame.

[0012] Preferably, a support rod is fixedly connected to the top of the support base, and a bearing plate and a lifting ring are fixedly connected to the support rod. An alcohol lamp is provided on the bearing plate, and the lifting ring is located at the bottom of the distillation flask.

[0013] Preferably, a limiting plate is fixedly connected to the support rod, and a positioning sleeve is slidably connected to the support rod, the positioning sleeve being fitted onto the outer surface of the distillation flask.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes a vertically designed spiral-shaped split condenser tube to achieve heat exchange and condensation with the condensate inside the condensation chamber. The spiral-shaped split condenser tube gradually decreases in height with each rotation, eliminating height differences. This allows the vapor droplets to flow completely out of the split condenser tube, preventing droplets from remaining inside. Simultaneously, the vapor generated in the distillation flask is diverted to the interior of the three split condenser tubes for condensation, resulting in stronger heat exchange between the condensate and the vapor in the split condenser tubes. This improves the condensation efficiency of the vapor, allowing it to condense more fully and quickly into droplets and flow into the sample collection container. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 and Figure 3 A distillation apparatus for chemical testing includes a distillation flask 1 and a condenser 2. The distillation flask 1 is used to contain chemicals. A steam delivery pipe 101 is fixedly connected to the mouth of the distillation flask 1. The condenser 2 is equipped with a multi-component flow mechanism. The flow mechanism includes a flow divider condenser 3 with a spiral design. Both the condenser 2 and the flow divider condenser 3 are vertically designed. The flow divider condenser 3 is located inside the condenser 2. An inlet port 301 and an outlet port 302 are respectively provided at both ends of the flow divider condenser 3.

[0025] like Figure 1 , Figure 2 and Figure 3 The top and bottom of the condensing chamber 2 are respectively provided with a first communicating vessel 4 and a second communicating vessel 5. The top of the inlet 301 passes through the top of the condensing chamber 2 and is fixedly installed with the bottom of the first communicating vessel 4. The outer surface of the inlet 301 is fixedly connected with the top of the condensing chamber 2. The bottom of the outlet 302 passes through the bottom of the condensing chamber 2 and is fixedly installed with the second communicating vessel 5. The outer surface of the outlet 302 is fixedly connected with the bottom of the condensing chamber 2. The diversion condensing pipe 3 is positioned inside the condensing chamber 2. One end of the steam conveying pipe 101 is fixedly installed at the pipe opening at the top of the first communicating vessel 4.

[0026] like Figure 1 and Figure 2 The top and bottom of the condensation chamber 2 are respectively fixedly connected to a condensate inlet pipe 6 and a condensate outlet pipe 7. The condensate inlet pipe 6 and the condensate outlet pipe 7 are connected to external pipelines, so that external condensate can be input into the interior of the condensation chamber 2 through the condensate inlet pipe 6 and then output outward through the condensate outlet pipe 7. Both sides of the condensation chamber 2 are fixedly connected to a concave positioning frame 8.

[0027] like Figure 1 and Figure 2 The bottom of the second communicating vessel 5 is provided with a sample collection container 9, and the bottom of the sample collection container 9 is provided with a support base 10. The sample collection container 9 is located below the second communicating vessel 5. After the evaporated sample condenses, it will eventually fall into the interior of the sample collection container 9 through the second communicating vessel 5.

[0028] like Figure 1 and Figure 4 A fixing rod 11 is fixedly connected to the top of the support base 10. A U-shaped support rod 12 is fixedly connected to the fixing rod 11. Both ends of the U-shaped support rod 12 pass through the concave positioning frame 8 to provide support for the concave positioning frame 8 and the condensation chamber 2. A fixing bolt 13 is provided on the concave positioning frame 8. The fixing bolt 13 passes through the U-shaped support rod 12 and is threadedly connected to the concave positioning frame 8 to fix the U-shaped support rod 12 and the concave positioning frame 8 together.

[0029] like Figure 1 The top of the support base 10 is fixedly connected to a support rod 14, and a bearing plate 15 and a lifting ring 16 are fixedly connected to the support rod 14. An alcohol lamp 17 is provided on the bearing plate 15. The alcohol lamp 17 heats the distillation flask 1 to distill the chemicals inside the distillation flask 1. The lifting ring 16 is located at the bottom of the distillation flask 1 to provide support for the distillation flask 1.

[0030] like Figure 1 A limiting plate 18 is fixedly connected to the support rod 14, and a positioning sleeve 19 is slidably connected to the support rod 14. The limiting plate 18 can restrict the downward movement of the positioning sleeve 19. The positioning sleeve 19 is sleeved on the outer surface of the distillation flask 1 and, together with the lifting ring 16, realizes the positioning of the distillation flask 1.

[0031] The working principle of the distillation apparatus for chemical testing provided by this utility model is as follows:

[0032] When the alcohol lamp 17 heats and distills the chemical products inside the distillation flask 1, the generated vapor can be input into the first communicating vessel 4 through the vapor delivery pipe 101, and then split into different input ports 301 through the first communicating vessel 4, and then enter the spiral-shaped split condenser 3. The condensate will be input into the condensation chamber 2 through the condensate input pipe 6. After heat exchange between the condensate inside the condensation chamber 2 and the external condensate, the condensate in the condensation chamber 2 is output through the condensate output pipe 7. The vapor in the split condenser 3 condenses into droplets, and flows into the second communicating vessel 5 through the output port 302, and finally falls into the sample collection container 9 through the second communicating vessel 5. The sample collection container 9 collects the distillation products of the chemical products inside the distillation flask 1, which can be easily transferred to external testing equipment for chemical testing.

[0033] Compared with related technologies, the distillation apparatus for chemical testing provided by this utility model has the following advantages:

[0034] This invention utilizes a vertically designed spiral-shaped split condenser 3 to achieve heat exchange and condensation with the condensate inside the condensation chamber 2. The spiral-shaped split condenser 3 gradually decreases in height with each turn, eliminating height differences. This allows the vapor droplets to flow completely out of the split condenser 3, preventing droplets from remaining inside. Simultaneously, the vapor generated in the distillation flask 1 is diverted to the three split condenser 3s for condensation, resulting in stronger heat exchange between the condensate and the vapor in the split condenser 3s. This improves the condensation efficiency of the vapor, allowing it to condense more fully and quickly into droplets and flow into the sample collection container 9.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
