Description

Technical Field

[0001] This utility model relates to the field of experimental instrument technology, specifically to a distillation apparatus that is easy to adjust and assemble. Background Technology

[0002] Distillation experiments are a common and very important pretreatment process in water quality and food testing in laboratories at all levels. Traditional distillation apparatus includes heating, condensation, and receiving parts, which are built independently according to experimental needs, making the operation cumbersome and inefficient. For distillation experiments involving gases with high viscosity, the following drawbacks exist: First, if the connection between the distillation flask and the condenser is made using a traditional conical ground joint where the condenser is placed directly on the distillation flask and connected under its own weight, this method easily leads to adhesion and inconvenience in disassembly. A spherical ground joint is required for this connection. Spherical ground joint condensers typically feature an upper inlet and a lower outlet. The gas distilled from the flask enters the condenser through the upper inlet, and the condensed liquid exits through the lower outlet. This means the mouth of the distillation flask is generally higher than the condenser. The condenser is usually secured with a clamp, which is prone to loosening and failure to hold the condenser properly over time. This instability during operation increases the risk of burns to personnel. Furthermore, the exposed tubing is messy and difficult to clean, leading to a cluttered laboratory surface and increasing the risk of accidents. Utility Model Content

[0029] Example 1

[0030] like Figures 1 to 6 The distillation apparatus shown includes a main housing 1, a cold water module 2, a distillation flask 6, a condenser tube 7, and a controller 8. The heating module includes a heating housing 102 and multiple heating bowls 5. The distillation flask 6 is placed in the heating bowls. The upper port of the distillation flask 6 is connected to the air inlet 703 at the upper end of the condenser tube 7 through a horizontal air guide tube 607. The condenser tube 7 is placed in a support 13 located inside the main housing 1. A pipeline groove 3 is connected to the main housing 1 via a lifting device. The pipeline groove 3 is located above the support 13, which allows the condenser tube 7 to be hidden, making the distillation apparatus neater overall. The pipeline groove 3 can be raised and lowered to facilitate the replacement of the condenser tube 7 and the horizontal air guide tube 607, as well as to accommodate condenser tubes 7 of different lengths.

[0031] Specifically, the lifting device includes a lifting sleeve 103, lifting legs 301, and limiting bolts 4. The lifting sleeve 103 is located on the left and right sides of the rear side of the main housing 1. The lifting legs 301 are inserted into the lifting sleeve 103. The lifting legs 301 have strip-shaped through holes 302. At least one limiting through hole is opened on the lifting sleeve 103 corresponding to the position of the strip-shaped through hole 302. A limiting nut 1031 is fixed in the limiting through hole. The limiting nut 1031 is equipped with a limiting bolt 4. The limiting bolt 4 passes through the limiting nut 1031 and the strip-shaped through hole 302. A locking washer 401 is provided inside the limiting bolt 4. The lifting legs are adapted to the lifting sleeve. The sleeve shape is provided. The locking pad 401 is made of hard material, such as iron sheet, copper sheet, hard plastic, etc. The locking pad 401 is provided with anti-slip rubber pad 402 on the side near the lifting leg 301. After the height of the pipeline groove 3 is adjusted, the limiting bolt 4 is screwed outward. The locking pad 401 and the anti-slip rubber pad are used to press the side wall of the lifting leg 301 and the lifting sleeve 103 together to play a fixing role. Of course, there can be two or more strip-shaped through holes. When the lifting leg 301 is a shape that matches the lifting sleeve, strip-shaped through holes 302 can be opened on both sides, and corresponding limiting through holes, limiting bolts and other structures can be set, which makes it more stable.

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 chilled water compressor can also be selected to provide chilled water to the condenser tube 7. When a chilled water module is not needed, it is not necessary to purchase a chilled water module and directly connect to tap water, using tap water as the condensate. This part is existing technology and will not be described in detail.

Inside the box, a shut-off valve 906 is installed on the water inlet pipe 901. Water is commonly used as the condensate, but other liquids can also be used. The advantages are that compared with each condenser pipe 7 being connected to the main water inlet pipe 901 and the main water outlet pipe 904 respectively, it can save the amount of pipeline and shut-off valve 906, facilitate control, and simplify pipeline connection. Compared with the case where all condenser pipes 7 are connected in series, the condensation effect can be maintained. The distillation flask 6 and the gas guide horizontal pipe 607, and the gas guide horizontal pipe 607 and the condenser pipe 7 are all connected by spherical ground glass stoppers and clamped by spherical ground glass clamps. Spherical ground glass clamps are existing technology and will not be described in detail here.

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.

[0043] 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, and a bottom through hole on the lower surface for passing through the lower conduit, such as the branch water outlet pipe 903.

[0044] 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.
