Description

Technical Field

[0001] This utility model relates to the field of experimental instrument technology, specifically to a modular distillation apparatus. Background Technology

[0002] Distillation experiments are a common and crucial pretreatment process in water quality and food testing in laboratories at all levels. Traditional distillation apparatuses include heating, condensation, and receiving components, which are independently built according to experimental needs. This process is cumbersome, inefficient, and involves complicated disassembly steps. Some automated distillation apparatuses are integrated units, with circulating water pumps, water tanks, and chilled water compressors all housed within the instrument. These integrated structures are bulky and occupy a large area, making disassembly inconvenient when workbench space is limited. Furthermore, some distillation systems can achieve condensation without a circulating water pump by directly connecting to tap water, rendering these additional components redundant and unable to be flexibly adjusted according to actual conditions.

[0003] For example, a fully automatic distillation apparatus with authorization announcement number CN 219540348 U includes an instrument support, a control box, and distillation components. The distillation components are configured in several groups, and each group of distillation components includes a distillation flask, a guide tube, a condenser tube, a water outlet hose, a glass dropper, and a collection bottle connected in sequence. The instrument support has a heating plate and a platform. The distillation flask is located above the heating plate, and the collection bottle is located above the platform. A flow-cutting device is provided outside the water outlet hose, and the flow-cutting device cuts off the water flow from the water outlet hose by squeezing. A control unit is provided inside the control box, and the heating plate and the flow-cutting device are both electrically connected to the control unit. It has several drawbacks: First, its circulating water pump and other components are located in the intelligent control area, which is an integrated structure of the control area and the work area, occupying a large area. If the circulating water pump is not needed, or if the workbench space is limited, it is inconvenient to disassemble flexibly. Second, its distillation flask is above the condenser tube, and the distilled gas must be directed downwards. The condenser tube in the comparative document is supported by a condenser clamp, which requires sufficient clamping force. In reality, the condenser clamp will loosen after long-term use, causing a decrease in clamping force, and the condenser tube may fall, posing a danger to the experiment. Third, during the general experiment, when the endpoint is reached, the water outlet hose between the condenser tube and the collection bottle is directly closed with a valve or the interception device in the comparative document. However, high-temperature steam will continue to be generated in the distillation flask, resulting in high pressure in the condenser tube and distillation flask, affecting the circulation system, or even causing experimental accidents such as tube detachment.

[0004] Furthermore, the condensers are currently connected in series, meaning the condenser inlet of the first condenser is connected to the main water inlet pipe, the condensate inlet of the subsequent condenser is connected to the condensate outlet of the previous condenser, and the condensate outlet of the last condenser is connected to the main water outlet pipe. This results in the first condenser having a good cooling effect, while the condensate temperature increases and the condensation effect decreases as the condenser progresses, leading to uneven experimental results.

[0015] Specifically, the pipeline trench has a side through hole on one side for passing through the main water inlet pipe and the main water outlet pipe, an upper through hole on the top for passing through the branch water inlet pipe, and a lower through hole on the lower surface.

[0016] The beneficial effects of this utility model are as follows: the cold water module and the main shell are detachable, which facilitates disassembly and assembly and is suitable for different test scenarios; the condenser tube is directly mounted on top of the distillation flask and is limited by the condenser rack, making assembly simple; the pipeline groove design can hide various pipelines and cables, making the experimental table more tidy; after titration, the pressure is automatically released, which is highly safe and can be widely used in environmental monitoring, disease control, hydrology, tap water, water supply and drainage, quality inspection, drug inspection, customs and other fields, as well as distillation experiments of volatile phenols, cyanides, ammonia nitrogen and other substances in water samples.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 , 2 A modular distillation apparatus as shown in Figures 3 and 4 includes a main housing 1, a cold water module, a distillation flask 6, a condenser 7, and a controller 8. A pipeline groove 3 is provided on the top of the main housing 1, and multiple condenser racks 4 are provided on the front side of the pipeline groove 3. A heating module is provided on the front side of the main housing 1, and a receiving plate 101 is provided at the bottom of the front side of the main housing 1. The cold water module is detachably provided on the rear side of the main housing 1.

[0031] The heating module includes a heating shell 102 and multiple heating bowls 5. The distillation flask 6 is placed in the heating bowls. The condenser rack 4 is correspondingly arranged with the heating bowls 5. The air inlet 703 at the lower end of the condenser tube 7 is placed at the air outlet of the distillation flask 6. The tube body of the condenser tube 7 is placed in the condenser rack 4. In this way, the condenser tube 7 is assembled at the air outlet of the distillation flask 6 by its own gravity. The condenser rack 4 plays a role in restricting the air flow from all sides.

[0032] Specifically, the cold water module includes a front panel 202 of the cold water housing 2 with a groove, that is, side plates 2021 are provided on both sides of the front panel 202, and side wings 2022 are provided on the front edge of the side plates 2021. The side wings 2022 are bolted to the cold water housing 2, and the front panel 202 is fastened to the rear side of the main housing 1.

[0033] Specifically, the lower side of the front panel 202 is provided with a snap-fit ​​plate 2023, and the rear side of the main housing 1 is provided with a snap-fit ​​groove. The snap-fit ​​plate 2023 can be inserted into the corresponding snap-fit ​​groove or protrusion on the rear of the main housing 1 to improve its stability, make it more aesthetically pleasing, and form a whole.

[0034] Specifically, the top of the cold water housing 2 is equipped with a cooling fan 201. The cold water housing 2 contains a water tank, a water pump, and a circulation pump. The circulation pump is connected to the water tank, and the water tank is connected to a water source through the water pump. The circulation pump provides a circulating cooling medium to the condenser tube 7 through the main water inlet pipe 901. The cooling medium discharged from the condenser tube 7 is discharged back to the water tank through the main drain pipe 904. According to customer needs, a cold water compressor can also be selected to provide cold water to the condenser tube 7. When a cold water module is not needed, it is not necessary to purchase a cold water module and directly connect to tap water to use tap water as condensate. This part is existing technology and will not be described in detail.

[0035] Specifically, the heating housing 102 has heat dissipation holes 1021 on its outer side.

[0036] Specifically, the receiving tray 101 is provided with a weighing module 12, which includes a weighing bracket 1201, a weighing cup 1202 on the weighing bracket 1201, a weighing sensor 1203 between the weighing cup 1202 and the weighing bracket 1201, a receiving bottle 10 placed inside the weighing cup 1201, and the liquid outlet 704 of the condenser 7 is connected to the receiving bottle 10 through a drain pipe. The weighing sensor 1203 transmits the monitored weight data to the controller 8 to monitor the changes in the distilled sample in order to determine whether the distillation endpoint has been reached.

[0037] Specifically, the main housing 1 is provided with a front protective plate to separate the receiving tray 101 from the pipeline behind it. The front protective plate 104 is provided with a front through hole 1041 for leading out the drain pipe connected to the drain port of the condenser tube and introducing the distillate into the receiving bottle 10.

[0038] The configuration and placement can be tailored to different testing scenarios. For example, if the test bench is spacious, the cold water module can be directly installed on the rear side of the main housing 1 for use as a whole, which is neat and aesthetically pleasing. When the test bench space is small, the cold water module can be removed and placed under the test bench. Simply extend the power lines, signal lines, water inlet main pipe 901, and drain main pipe 904 and connect them effectively. When the cold water module is not needed, the water inlet main pipe 901 can be directly connected to tap water or other condensate sources, and the drain main pipe 904 can be placed in a suitable receiver.

[0039] Example 2

[0040] like Figure 5 , 6The modular distillation apparatus shown also includes a buffer sleeve. The condenser 4 includes a vertical connecting plate 401, a lower limiting claw 402, and an upper limiting claw 403. The vertical connecting plate 401 has a mounting hole 405 for assembling the condenser 4 onto the pipeline groove 3. The buffer sleeve 405 is located outside the condenser tube 7, above the upper limiting claw 403, and can protect the condenser tube 7, preventing hard collisions or friction between the condenser 4 and the condenser tube 7, thus preventing damage to the condenser tube 7. The buffer sleeve 405 is made of elastic silicone, making it easy to put on the outside of the condenser tube 7.

[0041] Example 3

[0042] like Figure 7 , 8 A modular distillation apparatus as shown in 9 and 10 further includes a main water inlet pipe 901 and a main water outlet pipe 904, wherein the condenser tubes 7 are arranged in even numbers, such as... Figure 6 , 7 As shown, six condensers can be installed, with two adjacent condenser tubes 7 forming a group. The condensate inlet 701 of the preceding condenser tube 7 is connected to the main water inlet pipe 901 via a branch water inlet pipe 901. The condensate outlet 702 of the preceding condenser tube 7 is connected to the condensate inlet of the condenser tube 7 immediately following it via a branch water outlet pipe 903. The condensate outlet 702 of the following condenser tube 7 is connected to the main water outlet pipe 904 via a branch water outlet pipe 903, allowing the condensate to be discharged directly or into a water tank. A shut-off valve 906 is installed on the branch water inlet pipe 901. Water is commonly used as the condensate, but other liquids can also be used. The advantages are that compared to each condenser tube 7 being connected to the main water inlet pipe 901 and the main water outlet pipe 904 separately, it can save on the amount of piping and shut-off valve 906, facilitate control, and simplify the pipeline connection. Compared to the case where all condenser tubes 7 are connected in series, it can maintain the condensation effect.

[0043] Specifically, the outlet 704 of the condenser tube 7 is connected to the first outlet pipe 905, the first outlet pipe 905 is connected to the first port of the three-way valve 907, the second port of the three-way valve 907 is connected to the second outlet pipe 908, the second storage pipe 908 is connected to the receiving bottle 10, the third port of the three-way valve 907 is connected to the branch drain pipe 909, the branch drain pipe 909 is connected to the drain pipe 910, the drain pipe 910 is placed inside the main housing 1 and connected to the drain port 11 on the main housing 1. When the distilled liquid reaches the set amount, the first port is closed and the second port is opened, so that the high-pressure steam or condensed distillate in the distillation flask 6 and the condenser tube 7 can be discharged from the drain pipe 910 to achieve the purpose of depressurization.

[0044] Specifically, the pipeline trench 3 has a side through hole 301 on one side for passing through the main water inlet pipe 901 and the main drain pipe 902, an upper through hole 302 on the top for passing through the branch water inlet pipe 902, and a lower through hole on the lower surface for passing through the lower conduit, such as the branch water outlet pipe 903.

[0045] Specifically, it also includes a controller 8 and a buzzer. The controller 8 is connected to the weighing sensor 1203, the three-way valve 909, the shut-off valve 906, and the buzzer. The controller 8 adopts a PLC controller in the prior art. The heating bowl 201 is connected to the power switch. The controller 8 controls the start and stop of the heating bowl. When the distilled liquid reaches the set amount, the heating stops and an alarm is triggered. For convenience and practicality, a touch screen can also be selected as needed.

[0046] This utility model is not limited to the described embodiments. Anyone should know that any structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
