Description

Technical Field

[0001] This utility model relates to the field of distillation water machine technology, specifically to an automatic water supply switching device for a vertical rising film hot press distillation water machine. Background Technology

[0002] Distilled water is widely used as a high-purity water source in many fields such as industrial production, pharmaceutical manufacturing, and laboratory research. However, traditional distilled water preparation equipment often has certain limitations in the water supply process. For example, the water supply stability is poor. When the water supply system fails, such as when the water supply is interrupted or the water pressure is insufficient, the equipment usually cannot work properly, which forces the distillation process to be interrupted, affecting production efficiency and product quality. Moreover, the heat exchange efficiency of traditional equipment also needs to be improved. The heat exchange tube structure is simple, which results in insufficient heat transfer, low energy utilization, and increased production costs.

[0003] To address this issue, we have designed an automatic water supply switching device for a vertical rising film hot press distillation water machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic water supply switching device for a vertical rising film hot press distillation water machine, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic water supply switching device for a vertical rising film hot press distillation water machine, comprising a tank body. The interior of the tank body is divided into upper, middle, and lower cavities by two partitions. Multiple evenly distributed heat exchange tubes are vertically installed between the two partitions, and the heat exchange tubes connect the upper and lower cavities of the tank body. Multiple vertically spaced fins are fixed on the outer side of each heat exchange tube. The lower cavity of the tank body is provided with a water inlet, which is connected to the main water inlet pipe and the auxiliary water inlet pipe via a tee. The upper cavity of the tank body is provided with a steam-water outlet, and a steam-water separator is provided next to the steam-water outlet. The inlet of the steam-water separator is connected to the steam-water outlet of the tank body. The middle and bottom of the middle cavity of the tank body are respectively provided with a steam inlet and a condensate outlet. The steam inlet is connected to the steam inlet pipe and the return pipe via a tee, and the return pipe is connected to the steam outlet of the steam-water separator.

[0006] As a preferred embodiment of this utility model, the fins are in the shape of a conical cylinder, with the small opening of the fin facing upwards and fixed to the outer wall of the heat exchange tube.

[0007] As a preferred embodiment of this invention, a water pressure sensor is installed on the water inlet of the tank.

[0008] As a preferred embodiment of this utility model, the main water inlet pipe and the auxiliary water inlet pipe are each connected to two external industrial water heaters via water pumps. A first solenoid valve is installed on the main water inlet pipe, and a second solenoid valve is installed on the auxiliary water inlet pipe.

[0009] As a preferred embodiment of this utility model, a third solenoid valve is installed on the condensate outlet of the tank.

[0010] As a preferred embodiment of this invention, a level gauge is installed outside the central cavity of the tank, and the level gauge is located below the steam inlet of the tank.

[0013] Compared with the prior art, this utility model provides an automatic water supply switching device for a vertical rising film hot press distillation water machine, which has the following beneficial effects:

[0014] 1. This vertical rising film hot press distillation water machine automatically switches the water supply device.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-3 The automatic water supply switching device of the vertical rising film hot press distillation water machine includes a tank 1. The tank 1 is divided into three cavities (upper, middle, and lower) by two partitions 2. Between the two partitions 2, multiple heat exchange tubes 3 are vertically and evenly installed. These heat exchange tubes 3 connect the upper and lower cavities of the tank 1, allowing fluid to flow between the two cavities. Each heat exchange tube 3 has multiple vertically spaced fins 4 fixed on its outer side. The fins 4 are conical in shape, with their small openings facing upwards and fixed to the outer wall of the heat exchange tube 3. This design helps to increase the heat exchange area of ​​the heat exchange tube 3 and improve the heat exchange efficiency. At the same time, it can also prevent condensate from accumulating on the fins 4. A manhole can be provided on the tank 1 to facilitate the maintenance and cleaning of the heat exchange tubes 3 and fins 4 in the future.

[0022] The lower cavity of tank 1 is provided with a water inlet, which is connected to the main water inlet pipe 5 and the auxiliary water inlet pipe 6 via a T-junction. A water pressure sensor 10 is installed at the water inlet of tank 1. The water pressure sensor 10 is used to monitor the water pressure of tank 1 in real time and can provide timely feedback when the pressure is abnormal. The main water inlet pipe 5 and the auxiliary water inlet pipe 6 are both connected to two external industrial water heaters via water pumps. A first solenoid valve 11 is installed on the main water inlet pipe 5 and a second solenoid valve 12 is installed on the auxiliary water inlet pipe 6. By controlling the opening and closing of the first solenoid valve 11 and the second solenoid valve 12, the water supply between the main water inlet pipe 5 and the auxiliary water inlet pipe 6 can be switched.

[0023] The upper cavity of the tank body 1 is provided with a steam and water outlet. A steam and water separator 7 is provided next to the steam and water outlet. The inlet of the steam and water separator 7 is connected to the steam and water outlet of the tank body 1 to separate steam and water. A fourth solenoid valve 15 is installed on the outlet of the steam and water separator 7 to control the discharge of the separated water.

[0024] The middle and bottom of the intermediate cavity of tank 1 are respectively provided with a steam inlet and a condensate outlet. The steam inlet is connected to the steam inlet pipe 8 and the return pipe 9 through a tee. The steam inlet pipe 8 is connected to an external steam generator to provide steam for heating tank 1. The return pipe 9 is connected to the steam outlet of the steam-water separator 7. The separated steam can be diverted to the steam inlet of tank 1 for use through the return pipe 9. A third solenoid valve 13 is installed on the condensate outlet to control the discharge of condensate in the intermediate cavity of tank 1. A level gauge 14 is installed outside the intermediate cavity of tank 1. The level gauge 14 is located below the steam inlet of tank 1 and can monitor the condensate level in the intermediate cavity of tank 1 in real time.

[0025] Example 2: Based on Example 1, this example further adds automated control functionality. By introducing a PLC control system, automated control of each component of the device is achieved. The PLC control system is connected to components such as water pressure sensor 10, first solenoid valve 11, second solenoid valve 12, third solenoid valve 13, level gauge 14, and fourth solenoid valve 15 to monitor and control the operating status of the device in real time. When water pressure sensor 10 detects an abnormal inlet water pressure in tank 1, the PLC control system automatically controls the on / off state of the first solenoid valve 11 and the second solenoid valve 12 to provide normal water supply pressure. When level gauge 14 detects that the condensate level in the middle cavity of tank 1 is too high or too low, the PLC control system automatically controls the on / off state of the third solenoid valve 13 to control the condensate level.

[0026] Example 3: In actual operation, when the industrial water heater connected to the main water inlet pipe 5 malfunctions or the water supply is insufficient, the water pressure sensor 10 detects a drop in the inlet water pressure, and the system automatically opens the second solenoid valve 12 to start supplying water through the auxiliary water inlet pipe 6, thereby ensuring that the device can operate continuously and stably and realize the function of automatically switching water supply.

[0027] The conical cylindrical fins 4 on the outside of the heat exchange tube 3 can effectively increase the contact area with the steam during the steam heating process, so that the liquid in the heat exchange tube 3 can heat up faster and improve the distillation efficiency. At the same time, the condensed water droplets formed on the fins 4 will slide down the inclined surface of the fins 4 under the action of gravity and finally fall to the bottom of the middle cavity of the tank body 1, thus avoiding the accumulation of condensed water on the fins 4. Steam enters the middle cavity of the tank body 1 from the steam inlet pipe 8 and heats the heat exchange tube 3, so that the water temperature in the tube reaches the boiling point and forms rapidly rising steam bubbles on the inner wall of the tube, which drives the water to form a thin film flow on the tube wall. Finally, the steam and water in the tube enter the steam-water separator 7 from the steam-water outlet above the tank body 1.

[0028] The steam-water separator 7 separates steam and water. The separated steam flows back to the middle cavity of the tank 1 through the return pipe 9 to continue participating in the heating process, realizing the reuse of steam and reducing energy consumption. The separated water is discharged through the fourth solenoid valve 15.

[0029] During the operation of the device, the level gauge 14 monitors the condensate level in the intermediate cavity in real time. When the level is too high or too low, the system can open or close the third solenoid valve 13 according to the information fed back by the level gauge 14, so that the condensate level in the tank 1 is always kept within a suitable range, ensuring the safe and stable operation of the device.

[0030] Example 4: When maintenance or repair of the device is required, the first solenoid valve 11 and the second solenoid valve 12 can be closed first to stop the water inlet. Then, the external steam generator can be closed to stop the steam supply. After the pressure and temperature inside the tank 1 have dropped to a safe range, the third solenoid valve 13 can be opened to drain the condensate in the middle cavity of the tank 1.

[0031] During maintenance, the heat exchange tubes 3 and fins 4 can be inspected and cleaned to remove scale and impurities from the surface and ensure heat exchange efficiency. At the same time, the working status of components such as the water pressure sensor 10, the first solenoid valve 11, the second solenoid valve 12, the third solenoid valve 13, the fourth solenoid valve 15, and the level gauge 14 can be checked. If any damage or malfunction is found, it should be replaced or repaired in a timely manner.

[0032] After maintenance, restart the external steam generator to supply steam. Depending on actual needs, open the first solenoid valve 11 or the second solenoid valve 12 to start water intake and restore the device to normal operation.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
