Description

Technical Field

[0001] This invention relates to the field of veterinary drug manufacturing technology, specifically to a multi-effect distillation water machine with adjustable water production for veterinary drug manufacturing. Background Technology

[0002] Veterinary drugs refer to substances used to prevent, treat, or diagnose animal diseases or to purposefully regulate animal physiological functions. Veterinary drug manufacturing refers to the production process of substances used to prevent, treat, or diagnose animal diseases or to purposefully regulate animal physiological functions. In the process of veterinary drug manufacturing, ordinary water may contain organic compounds, such as humic substances and microbial metabolites. These organic impurities may interact with drug components during the manufacturing process, leading to drug deterioration or reduced efficacy. Therefore, distilled water is used. Distilled water provides a relatively pure environment, reducing the interference of external factors on the stability of drug components.

[0003] A water distillation machine is a device that uses the principle of distillation to produce high-purity distilled water. It heats the raw water to boiling point and vaporizes it, turning the water into water vapor. Various impurities in the water (including insoluble solids, most salts, organic matter, microorganisms, etc.) remain in the raw water or the residue after evaporation because they have high boiling points or are not volatile. The water vapor then enters a cooling system, where it is cooled and re-condensed into liquid water, thus obtaining highly pure distilled water.

[0004] However, currently, 1. Common types include falling film evaporators, where raw water is evenly distributed on the inner wall of the evaporator tube through a special distribution device, forming a water film, which then evaporates under heating. This method allows for full contact between the water and the heating surface, improving evaporation efficiency. However, this evaporation method easily accumulates scale on the inner wall of the pipes; 2. Multi-effect water distillers typically contain multiple effects connected in series. After the raw water is boiled and condensed in the first effect, the resulting distilled water enters the next effect for further processing. However, some raw water, after reaching its first boiling point, is liquefied by the condensation equipment and enters the next device. Some devices have the problem of pouring all of this collected condensate into the next processing chamber. However, in actual production, this is addressed by increasing the amount of raw water and connecting it with the first effect. The mixing of water vapor after secondary liquefaction can, to some extent, buffer the impact of water quality fluctuations on the final distilled water quality. If this level of mixing is not achieved, the pH of the distilled water will deviate from the ideal range. 3. During boiling, as the water temperature rises to its boiling point, the water changes from a liquid to a gaseous state, forming a large amount of water vapor. Simultaneously, the solubility of gases originally dissolved in the water (such as air) decreases with increasing temperature, causing bubbles to precipitate. As the water vapor flows towards the condensation zone, the bubbles trapped within it are also carried along. Bubbles have poor thermal conductivity; when they enter the condensation zone, they form a film on the surface of the condenser tube, hindering sufficient contact between the water vapor and the condenser, thus reducing the condensation effect and prolonging processing time. These factors, including the inability to adequately meet user needs, present drawbacks. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-effect distillation water machine with adjustable water production for veterinary drug manufacturing, which solves the problems mentioned in the background art, such as the inability to control the flow rate between the series-connected effectors and the inability to carry air bubbles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-effect distillation water machine with adjustable water production for veterinary drug manufacturing, comprising a first boiling unit, a first processing chamber installed at one end of the outer wall of the first boiling unit, the bottom of the first processing chamber connected to the top of a second boiling unit via a pipe, a second processing chamber installed at one end of the second boiling unit, a distilled water collection tank installed below the second processing chamber, the first boiling unit and the first processing chamber, and the second boiling unit and the second processing chamber being connected through guide pipes, condenser tubes installed inside the first and second processing chambers respectively, and a flow control plate installed below each condenser tube, the flow control plate being rotatably connected to the first... Inside the processing chamber and the distilled water collection tank, the first and second boiling devices are respectively equipped with metal sealing chambers and stirring components.

The condenser tube in the second processing chamber is inclined, with its narrower end located at the lowest point of the surface of the second processing chamber.

[0013] Optionally, a second baffle is provided inside the second processing chamber at the narrower end of the internal condenser tube, and the edges of the first baffle and the second baffle are both arc-shaped and respectively attached to the inner wall of the corresponding second boiling device and the second processing chamber, and the tops of the first baffle and the second baffle are both inclined.

[0017] This invention provides a multi-effect distillation water machine with adjustable water production for veterinary drug manufacturing, which has the following features:

[0018] Beneficial effects:

[0019] This multi-effect distillation water machine, used for veterinary drug manufacturing, features adjustable water production. The metal seal heats the raw water evenly in the middle, avoiding the formation of localized high-temperature areas. This allows heat to be evenly distributed throughout the main body of the water, improving heat utilization efficiency. This uniform heating method reduces the conditions for scale formation. Furthermore, the first and second boiling chambers and the metal-sealed chamber are relatively independent, making scale cleaning easier and reducing equipment maintenance difficulty and costs. Unlike traditional falling film evaporators, which are prone to scale formation on the inner walls of pipes and are difficult to clean.

[0020] This multi-effect distillation water machine with adjustable water production capacity for veterinary drug manufacturing features an added stirring component. Its curved and curved blades can evenly stir the raw water, avoiding local overheating and the generation of a large number of bubbles. It can also break up small bubbles that have already formed, effectively reducing the number of bubbles entering the condensation zone. The structure of the condenser tubes in the first and second processing chambers gradually narrows from bottom to top and matches the direction of steam movement, allowing water vapor to pass through and contact the condenser tubes smoothly. At the same time, the condenser tubes are connected to the external cooler to form a stable heat exchange channel, ensuring efficient condensation.

[0021] This multi-effect distillation water machine with adjustable water production capacity for veterinary drug manufacturing has a raw water filter element installed inside the pipeline that directly delivers the raw water. The raw water is filtered as it enters the equipment. The first filter element installation slot is equipped with multiple filter elements to achieve a progression from coarse filtration to fine filtration, which can effectively prevent impurities from entering the core components. The layout of the equipment reduces the bends and length of the pipeline. The design of each component, such as the first baffle and the second baffle, is reasonable and conducive to steam transmission and condensate collection.

[0022] This multi-effect distillation water machine for veterinary drug manufacturing, with adjustable water production, combines a drainage pipe with a pipeline equipped with a flow meter and a control plate. The flow meter initially monitors the flow rate, while a pressure sensor at the bottom of the control plate senses the weight of the distilled water in real time. This dual monitoring and control mechanism can accurately control the amount of distilled water extracted, which is of great significance in fields with strict requirements for the quality and quantity of distilled water.

[0023] This multi-effect distillation water machine for veterinary drug manufacturing, with adjustable water production, uses a vacuum machine connected to the first and second processing chambers to create a negative pressure environment. This causes high-temperature water vapor to flow and condense rapidly under the pressure difference, improving heat exchange efficiency and distillation speed. Meanwhile, the ceramic filter element installed in the second filter element mounting slot at the front end of the guide tube can effectively intercept impurities carried in the water vapor, improving the purity of the distilled water.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Please see Figures 1 to 7 This invention provides a technical solution: a multi-effect distillation water machine with adjustable water production for veterinary drug manufacturing, comprising a first boiling vessel 1, a first processing chamber 2 installed at one end of the outer wall of the first boiling vessel 1, the bottom of the first processing chamber 2 being connected to the top of a second boiling vessel 3 via a pipe, a second processing chamber 4 installed at one end of the second boiling vessel 3, and a distillation water collection tank 5 installed below the second processing chamber 4. The first boiling vessel 1 and the first processing chamber 2, as well as the second boiling vessel 3 and the second processing chamber 4, are all connected by a guide pipe 6. A condenser pipe 7 is installed inside the first processing chamber 2 and the second processing chamber 4, respectively. A flow control plate 8 is installed below the condenser pipe 7, and the flow control plate 8 is rotatably connected to the first processing chamber 2 and the distillation water collection tank, respectively. Inside the first boiling vessel 1 and the second boiling vessel 3, metal sealing chambers 9 and stirring components 10 are respectively installed. The stirring components 10 are distributed around the center point of the metal sealing chamber 9. The first boiling vessel 1, the second boiling vessel 3 and the distilled water collection tank 5 are connected as a whole by the frame. The first processing chamber 2 and the second processing chamber 4 are both fixed to the top of the frame by the hanger. The distilled water collection tank 5 is located on the side of the frame. A vacuum machine 11 is installed inside the frame corresponding to the bottom of the first boiling vessel 1 and the second boiling vessel 3. The top of the second boiling vessel 3 is connected to the water distribution tank 12 through a pipe. The first processing chamber 2 is located between the first boiling vessel 1 and the water distribution tank 12. The top of the water distribution tank 12 has a pipe and the inner wall of the pipe is threaded with a raw water filter 13.

[0036] The stirring component 10 includes a driving gear 1001, a driven gear 1002, and a blade 1003. The driving gear 1001 and the driven gear 1002 are rotatably connected to the bottom of the outer wall of the first boiling vessel 1 and one side of the outer wall of the second boiling vessel 3, respectively. The driven gear 1002 extends through a shaft at its center to the interior of the first boiling vessel 1 and the second boiling vessel 3, respectively. The blade 1003 is rotatably connected to the interior of the first boiling vessel 1 and the second boiling vessel 3, respectively.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the first boiling vessel 1 and the second boiling vessel 3 are vertically distributed, and the second boiling vessel 3 is smaller than the first boiling vessel 1. Both the first boiling vessel 1 and the second boiling vessel 3 are made of double-layer metal material, and an insulation layer is installed between the inner and outer layers. The layout of the first boiling vessel 1, the second boiling vessel 3 and the first processing chamber 2 reduces the bends and lengths of the pipes, which is conducive to the rapid transmission of steam and improves the distillation efficiency. The insulation layer installed between the double-layer metal material can not only effectively prevent heat from being lost from the inside to the outside, but also prevent the outer surface temperature from being too high. This greatly reduces the risk of burns to personnel operating around the equipment due to accidental contact with the equipment surface.

[0038] In this embodiment, as Figure 3 and Figure 4 As shown, the raw water filter element 13 is composed of three sets of identical first filter element mounting grooves 1301 tightly fitted together. The two lowest sets of first filter element mounting grooves 1301 each have a connecting joint 1302 at the top axis, and the two highest sets of first filter element mounting grooves 1301 each have a slot at the bottom axis for threaded connection of the connecting joint 1302. Simultaneously, the raw water filter element 13 is threadedly connected to the inner wall of the pipe opened in the top cover of the first boiler 1, and the raw water filter element 13 located above the first boiler 1 has the same specifications as the inner diameter of the top pipe opening of the first boiler 1. By placing the raw water filter element 13 inside the pipe that directly transports the raw water, filtration can be performed as soon as the raw water enters the equipment. This design prevents impurities from entering subsequent core components such as the boiling vessel, reducing their accumulation inside the equipment. Consequently, the scale and other impurities produced during the boiling process are reduced, thus improving the efficiency and quality of distillation. The first filter element installation slots 1301 are connected to the inner wall of the pipe via threads, and the upper and lower parts can also be fitted together using the threaded structure of the connector 1302. The structure of the connector 1302 provides gripping points, making installation and disassembly convenient. At the same time, PP cotton, activated carbon, and ultrafiltration membrane filter elements are installed from top to bottom inside the first filter element installation slots 1301, realizing a gradual progression from coarse filtration to fine filtration. The synergistic effect of the three filter elements optimizes the raw water filtration effect.

[0039] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3 As shown, the metal sealing cavity 9 is welded to the center point of the bottom wall of the first boiling vessel 1 and the center point of one end of the second boiling vessel 3. The metal sealing cavity 9 is a hollow cavity with several sets of electric heating tubes distributed inside. Temperature controllers 14 electrically connected to the electric heating tubes are installed on the outer walls of both the first boiling vessel 1 and the second boiling vessel 3. Compared with the commonly used falling film evaporator, which easily forms scale on the inner wall of the pipe due to the contact method between the water film and the heating surface and the local temperature difference, the metal sealing cavity 9 heats the raw water uniformly, avoiding the formation of local high-temperature areas and reducing the conditions for scale formation. Even if a small amount of scale is formed, since the first boiling vessel 1, the second boiling vessel 3 and the metal sealing cavity 9 are all relatively independent structures, it is more operable than the scale cleaning of the inner wall of the pipe in the falling film evaporator. It is more convenient to clean scale in an open environment, without the need to disassemble and clean the complex piping system, thus reducing the difficulty and cost of equipment maintenance.

[0040] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the blades 1003 are arranged in a ring around the axis of the metal sealing cavity 9, and a first baffle 15 is provided at one end of the inner wall of the second boiling vessel 3. The first baffle 15 is distributed relative to the metal sealing cavity 9 distributed in the second boiling vessel 3. Since high-temperature water will produce bubbles, when bubbles enter the condensation zone with water vapor, impurities may be adsorbed on the surface of the bubbles. When the bubbles enter the condensation zone and break, these impurities will enter the distilled water. At the same time, when the bubbles enter the cold zone, they will also form a gas film on the surface of the condenser tube 7, which will hinder the water vapor from fully contacting it, thereby reducing the condensation effect and prolonging the processing time. By adding a stirring element 10, whose blades 1003 are arc-shaped and curved, it can cover a larger stirring area during rotation. It rotates at an equal angle around the axis of the metal sealing cavity 9, so that the raw water is uniformly stirred. This can prevent the water from overheating in a local area and generating a large number of bubbles. For the small bubbles that have already formed, the movement of the water flow during stirring can break these bubbles apart, thereby effectively reducing the number of bubbles entering the condensation zone with water vapor.

[0041] In this embodiment, as Figure 2 , Figure 5 and Figure 7As shown, the first processing chamber 2 is vertically distributed, and the second processing chamber 4 is inclined. The condenser tube 7 is spirally coiled, wider at one end and gradually narrowing along the extension direction of the tube body. The condenser tube 7 in the first processing chamber 2 is vertically distributed, with its wider end located above the inlet connecting the first processing chamber 2 and the guide pipe 6. The condenser tube 7 in the second processing chamber 4 is inclined, with its narrower end located at the lowest point of the surface of the second processing chamber 4. Both ends of the condenser tube 7 extend through and beyond the first processing chamber 2 and the second processing chamber 4, respectively. Sealing rubber gaskets are applied to the corresponding openings of the condenser tube 7 outside the first and second processing chambers 2 and 4. When steam enters the first processing chamber 2 from the first boiling vessel 1, the steam itself tends to move upwards due to heat, and the gradually narrowing structure of the condenser tube 7 matches the upward movement direction of the steam. When steam flows from the first boiling vessel 1 into the first processing chamber 2, the wider inlet of the condenser tube 7 is designed to allow the steam to pass smoothly through and contact the condenser tube 7, thus accommodating more steam. As the steam flows upward, the tube diameter gradually decreases, compressing and guiding the steam. As the steam condenses into water upon contact with the narrowing condenser tube 7, the condensate flows downward along the condenser tube 7 under gravity. The condenser tube 7 in the second processing chamber 4 operates on the same principle. Furthermore, the tubes at both ends of the condenser tube 7 penetrate the chamber and can connect to an external cooling unit, ensuring a stable and direct heat exchange channel. This allows the cooling medium to circulate efficiently within the condenser tube 7, carrying away the heat from the steam and achieving rapid condensation. The sealing rubber gasket effectively fills the tiny gap between the condenser tube 7 and its opposite external interface in the processing chamber, ensuring a tight seal.

[0042] In this embodiment, as Figure 6 and Figure 7As shown, a second baffle 16 is provided inside the second processing chamber 4 at the narrower end of its internal condenser tube 7. The edges of both the first baffle 15 and the second baffle 16 are arc-shaped and respectively fit against the inner walls of the corresponding second boiling vessel 3 and the second processing chamber 4. Furthermore, the tops of both the first baffle 15 and the second baffle 16 are inclined. Since the second boiling vessel 3 is arranged laterally, water may distribute too widely within it without restriction. The presence of the first baffle 15 prevents water from spreading to excessive areas, ensuring that the water remains within the metal seal. The area around the heat source in cavity 9 ensures that heat is concentrated in the main part of the water. When water vapor comes into contact with the condenser tubes 7, which are also inclined in the second processing cavity 4, the resulting condensate will eventually fall under gravity through the narrower end of the condenser tube 7 and flow into the distilled water collection tank 5 through the drainage pipe 17. Without the obstruction of the second baffle 16, splashing may occur due to the gravity of the condensate and the collision with the bottom of the second processing cavity 4. The presence of the second baffle 16 not only reduces the occurrence of condensate splashing but also guides it into the distilled water collection tank 5 through the drainage pipe 17.

[0043] In this embodiment, as Figure 2 , Figure 5 and Figure 7 As shown, the bottom of the second processing chamber 4 is provided with a drainage pipe 17, which is also inclined. A strip-shaped slot, communicating with the drainage pipe 17, is opened through the bottom of the second processing chamber 4. The lowest end of the drainage pipe 17 is connected to the top of the distilled water collection tank 5 via a pipe. The bottoms of both the first processing chamber 2 and the distilled water collection tank 5 are funnel-shaped. The control disc 8 is rotatably connected to the funnel-shaped cavities of the first processing chamber 2 and the distilled water collection tank 5 via servo motors. The top of the control disc 8 has a concave cavity within an annular rim, and a movable panel is rotatably connected to one end of its annular rim. A pressure sensor is installed at the bottom of the volume control plate 8. By combining the drainage pipe 17 with a pipe equipped with a flow meter and then installing the volume control plate 8, the extraction volume of distilled water is controlled. The flow meter can initially monitor the flow rate entering the distilled water collection tank 5, while the pressure sensor at the bottom of the volume control plate 8 can sense the weight of the distilled water on the surface of the volume control plate 8 in real time. When the set parameters are reached, the delivery path is cut off by controlling the solenoid valve. This dual monitoring and control mechanism is more accurate than using a flow meter alone. In fields such as veterinary drug manufacturing where the quality and quantity of distilled water are strictly required, it can ensure that the amount of distilled water extracted each time is accurate.

[0044] In this embodiment, as Figure 1 and Figure 2As shown, the guide pipe 6 is trumpet-shaped, and the guide pipe 6 located between the first boiling vessel 1 and the first processing chamber 2 has its larger opening threadedly connected to the inner wall of the corresponding through hole on the outer wall of the first boiling vessel 1. The guide pipe 6 located between the second boiling vessel 3 and the second processing chamber 4 has its larger opening threadedly connected to the inner wall of the through hole through which the end cap of the second boiling vessel 3 passes. At the same time, the inner wall of the larger opening side of the guide pipe 6 is threadedly connected to the second filter element mounting groove 18. As an important component for transporting water vapor, the shape of the guide pipe 6 reduces the resistance to water vapor transport and provides a spacious channel for water vapor to naturally and smoothly transition into the collection device. The inner wall of its front end is threadedly connected to the second filter element mounting groove 18, which contains a ceramic filter element. When water vapor passes through the ceramic filter element installed in the second filter element mounting groove 18, these tiny pores can effectively intercept tiny impurity particles, microorganisms, and some chemical substances carried in the water vapor, thereby improving the purity of the distilled water.

[0045] In this embodiment, as Figure 2 As shown, both the first processing chamber 2 and the second processing chamber 4 are connected to the vacuum machine 11 via pipes, and pressure gauges 19 are installed on the outer walls of both chambers. When the vacuum machine 11 is connected to and operates in the first and second processing chambers 2 and 4, it extracts air from the chambers, reducing the pressure and creating a negative pressure environment. Based on the principle of gas flow, gas always flows from high-pressure areas to low-pressure areas. In this situation, the high-temperature steam in the first boiling vessel 1 and the second boiling vessel 3 will flow towards the lower-pressure chambers 2 and 4 under the pressure difference, allowing the steam to condense more quickly on the condenser 7, thereby improving heat exchange efficiency and accelerating the entire distillation process.

[0046] In summary, this multi-effect distillation water machine for veterinary drug manufacturing with adjustable water production capacity connects the pipes on the top cover of the first boiling vessel 1 and the water distribution tank 12 to an external water supply device. The flow rate of the incoming raw water is monitored in real time by a flow meter (LDG-SUP) installed on the pipes. As the raw water passes through the pipes, it comes into full contact with the raw water filter element 13. The first filter element installation groove 1301 progressively filters the raw water. As the raw water continues to flow in, the filtered raw water enters the first boiling vessel 1 and the second boiling vessel 3. After the flow meter detects the preset parameters, it transmits a signal to the control system. Upon receiving the signal from the electromagnetic flow meter, the control system sends a command to the solenoid valve electrically connected to the flow meter. The solenoid valve (4V2)... 10-08) Close the valve to cut off the fluid channel, thereby ensuring the quantitative distribution of liquid inside the first boiler 1 and the second boiler 3. At this time, turn on the power supply located on one side of the first boiler 1. The electric heating tube in the metal sealed cavity 9 inside the first boiler 1 heats the raw water under the control of the temperature controller 14. At the same time, the drive gear 1001 drives the driven gear 1002 to rotate under the drive of the servo motor, thereby causing the blades 1003 to stir the raw water, ensuring that the raw water is heated evenly, avoiding local overheating and generating a large number of bubbles, and breaking up the small bubbles that have already formed. During the boiling process inside the first boiler 1, the air inside the first processing chamber 2 and the second processing chamber 4 is extracted using a vacuum machine 11 (GDZK-400) and through the pipes, and the guide pipe 6 needs to be closed. The valve is installed on the top, and the pressure gauge 19 on the surface of the first processing chamber 2 and the second processing chamber 4 can monitor the internal pressure value in real time. The temperature is also monitored in real time by the temperature controller 14 (STC-200+). The operator can ensure that the liquid temperature in the first boiling vessel 1 is kept within the optimal distillation temperature range. When the preset parameters are reached, the guide pipe 6 opens the valve based on the principle of the solenoid valve on the pipe above the first boiling vessel 1 under the command of the control body. Based on the principle of gas flow, gas always flows from the high pressure area to the low pressure area. Water vapor will flow into the first processing chamber 2 through the guide pipe 6 between the first boiling vessel 1 and the first processing chamber 2. The filter element of the second filter element mounting groove 18 at the front end of the guide pipe 6 can fully filter the high temperature water vapor. At the same time, due to Water vapor, due to its heat, tends to rise. As the steam flows upward, the pipe diameter gradually decreases, compressing and guiding the steam. Upon contact with the narrowing condenser tube 7, the steam condenses into water. Under gravity, the condensate flows downward along the condenser tube 7 and falls into the concave cavity on the surface of the control plate 8 within the first processing chamber 2. A pressure sensor monitors the weight change in real time. The control plate 8, connected to the first processing chamber 2 via a servo motor, can precisely adjust its angle based on the pressure sensor data. As condensate accumulates, when the weight reaches a preset parameter value, the control plate 8, driven by the servo motor, flips, opening the movable panel at a certain angle and allowing the condensate to flow out into the funnel-shaped cavity below.Meanwhile, according to the flow meter and solenoid valve installed in the pipeline between the first processing chamber 2 and the second boiling vessel 3, the condensate collected in the first processing chamber 2 is transported to the second boiling vessel 3 through a preset mechanism and fully mixed with the raw water that has entered through the water distribution tank 12. The water mixture inside the second boiling vessel 3 is heated again in the same way as the boiling process inside the first boiling vessel 1. Due to the structure of the first baffle 15 inside, the diffusion of the water is effectively prevented. The temperature controller 14 monitors the temperature in real time. When the preset parameters are reached, the guide pipe 6, based on the principle of the solenoid valve in the pipeline above the first boiling vessel 1, opens under the command of the control body. Water vapor in the second boiling vessel 3 flows into the second processing chamber 4 through the guide pipe 6 on one side. The water enters and fully contacts the condenser 7 inside the second processing chamber 4. Due to the inclined structure of the condenser 7, the water vapor after condensation is also drawn into the drainage pipe 17 through the through hole at the bottom of the second processing chamber 4 under gravity. The inner wall of the drainage pipe 17 is coated with polytetrafluoroethylene, which minimizes the resistance encountered by the condensate when flowing through its inner wall. Finally, the water enters the distilled water collection tank 5 through the through hole between the drainage pipe 17 and the distilled water collection tank 5 and flows into the control plate 8. When the operator extracts the water, only the external flow meter and solenoid valve of the distilled water collection tank 5 are needed to accurately extract the required amount of water. At the same time, both the first boiling vessel 1 and the second boiling vessel 3 are equipped with drain outlets at the bottom, which can be opened to remove excess wastewater.
