Abstract
Description
Technical Field
[0001] This utility model relates to laboratory distillation water machine technology, specifically a laboratory distillation water machine. Background Technology
[0002] Distilled water is used in laboratories. Distilled water is pure water obtained through distillation. In the distillation process, water needs to be heated to evaporate into steam, which is then cooled and condensed into distilled water. Because the amount of distilled water used in laboratories is relatively small, laboratory distillation machines are small in size, and sometimes distilled water is even boiled manually. Existing laboratory distillation machines tend to waste heat and have a slow condensation rate. Utility Model Content
[0003] The purpose of this invention is to provide a laboratory water distillation machine with a simple structure. The steam is easily condensed when it passes through the water supply pipe above, and the supplied water is heated at the same time. It has a high utilization rate of thermal energy, strong practicality, and is suitable for widespread application.
[0004] This utility model provides the following technical solution: a laboratory distillation water machine, including a distillation tank, a water tank fixedly provided at the bottom of the distillation tank, a heating seat provided below the water tank, a support column fixedly provided at the center of the water tank, the support column passing through the water tank and a breathable wall fixedly provided above the water tank;
[0005] The top of the distillation tank is provided with a top cover, and a connecting seat is provided at the center of the top cover. A water supply pipe is connected to the outside of the connecting seat. A layer of coiled pipe is provided above the air-permeable wall of the support column. The water supply pipe is connected to the coiled pipe. A water injection cavity is provided inside the support column. The coiled pipe is connected to the water injection cavity.
[0006] A reflux pipe is installed on the connecting seat. The reflux pipe is connected to the inside of the distillation tank. The reflux pipe is V-shaped, and the bottom of the V-shape is a water receiving container.
[0007] Preferably, a distillation water tank is formed between the water tank and the inner wall of the distillation tank. The top cover and the vent wall are conical and obliquely downward from the middle. The edge of the vent wall extends to the top of the distillation water tank. The distillation tank is provided with a drain pipe at the bottom of the distillation water tank.
[0008] Preferably, a guide strip is fixedly provided on the lower wall of the coiled tube. The cross-section of the guide strip is conical. An array of vent holes is provided on the vent wall. The position of the vent holes is offset from that of the guide strip.
[0009] Preferably, the support column is located inside the water tank and has an opening that penetrates into the water injection chamber, and the water supply speed of the water supply pipe is matched with the distillation speed of the water tank.
[0010] The beneficial effects of this utility model are as follows: It has a simple structure, facilitates steam condensation when passing through the upper water supply pipe, and simultaneously heats the supplied water, resulting in high utilization of thermal energy and strong practicality. Specifically:
[0011] This invention features a coiled tube. After heating the water in the water tank to generate steam, the steam rises and passes through the ventilated wall. When it passes through the coiled tube, the temperature of the coiled tube is low due to the incoming water, making it easier for the steam to condense on the coiled tube. The heat of the steam also acts on the incoming water, heating it. After distilled water condenses in the coiled tube, it drips down the guide strip onto the ventilated wall. The distilled water generated on the ventilated wall and the dripping distilled water slide into the distilled water tank for easy collection. The steam passing through the coiled tube enters the return pipe for conventional distilled water collection. Attached Figure Description

[0020] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] See Figure 1-2 A laboratory distillation water machine includes a distillation tank 1, a water tank 2 fixedly mounted at the bottom of the distillation tank 1, a heating seat 7 located below the water tank 2, the heating seat 7 heating the water in the water tank 2, a support column 13 fixedly mounted at the center of the water tank 2, the support column 13 penetrating the water tank 2 and a breathable wall 10 fixedly mounted above the water tank 2, a top cover 3 on the top of the distillation tank 1, a connecting seat 4 at the center of the top cover 3, a reflux pipe 5 installed on the connecting seat 4, the reflux pipe 5 communicating with the inside of the distillation tank 1, the reflux pipe 5 being V-shaped, with a water receiving container at the bottom of the V-shape, and water vapor overflowing from the distillation tank 1 being collected as distilled water using conventional methods.
[0022] See Figure 1-3The connecting seat 4 is externally connected to a water supply pipe 6. The support column 13 is located above the vent wall 10 and has a coiled tube 12. The water supply pipe 6 communicates with the coiled tube 12. The support column 13 has a water injection chamber 14. The supplied water is heated after passing through the coiled tube 12. The support column 13 has an opening in the water tank 2 that penetrates into the water injection chamber 14. The supplied water flows into the water tank 2. The coiled tube 12 communicates with the water injection chamber 14. A guide strip 15 is fixed on the lower wall of the coiled tube 12. The cross-section of the guide strip 15 is conical. After distilled water condenses in the coiled tube 12, it drips down along the guide strip 15. The air vent 10 has an array of ventilation holes 11. The ventilation holes 11 are offset from the guide strip 15 to prevent dripping distilled water from entering the ventilation holes 11. The water tank 2 and the inner wall of the distillation tank 1 form a distilled water tank 8. The top cover 3 and the air vent 10 are conical and tilted downwards from the middle to allow distilled water to slide down the wall to the edge. The edge of the air vent 10 extends above the distilled water tank 8. The distillation tank 1 is located at the bottom of the distilled water tank 8 and is provided with a drain pipe 9. The water supply speed of the water supply pipe 6 is matched with the distillation speed of the water tank 2 to make the distillation tank 1 work in a cycle.
[0023] This utility model of a laboratory distillation water machine has a simple structure. Steam is easily condensed when it passes through the water supply pipe above, and the supplied water is heated at the same time. It has a high utilization rate of thermal energy, strong practicality, and is suitable for widespread application.
[0024] For specific usage, please refer to... Figure 1-3 After the water in the water tank 2 is heated to generate steam, the steam rises and passes through the ventilated wall 10. When it passes through the coiled tube 12, the temperature of the coiled tube 12 is low due to the water supply passing through it. The water vapor is more likely to condense on the coiled tube 12 when it passes through, and the heat of the water vapor will act on the water supply, heating it. After distilled water is condensed in the coiled tube 12, it will drip down the guide strip 15 onto the ventilated wall 10. The distilled water generated on the ventilated wall 10 and the dripping distilled water will slide into the distilled water tank 8 for easy collection. The water vapor passing through the coiled tube 12 enters the return pipe 5 for conventional distilled water collection.
