Description

Technical Field

[0001] The invention relates to the technical field of veterinary drug manufacturing, in particular to a multi-effect distilled water machine with adjustable water production used for veterinary drug manufacturing. Background Art

[0002] Veterinary drugs refer to substances used to prevent, treat, diagnose animal diseases or purposefully regulate animal physiological functions. Veterinary drug manufacturing refers to the production process of substances used to prevent, treat, diagnose animal diseases or purposefully regulate animal physiological functions. In the process of veterinary drug manufacturing, because ordinary water may contain organic compounds, such as humus, microbial metabolites, etc., these organic impurities may interact with drug ingredients during the veterinary drug manufacturing process, causing the drug to deteriorate or reduce the efficacy, so distilled water is used. Distilled water can provide a relatively pure environment and reduce the interference of external factors on the stability of drug ingredients.

[0003] A water distiller is a device that uses the principle of distillation to prepare high-purity distilled water. It heats the raw water to boiling and vaporizes it, turning it into water vapor. Various impurities in the water (including insoluble solids, most salts, organic matter, microorganisms, etc.) remain in the raw water or the residual part after the raw water evaporates due to their high boiling point or lack of volatility. The water vapor then enters the cooling system, where it is cooled and recondensed into liquid water, thus obtaining distilled water with a higher purity.

[0004] However, at present, 1. Common falling film evaporators are used. Raw water is evenly distributed on the inner wall of the evaporation tube through a special distribution device to form a water film, and then evaporates under the action of heating. This method can make the water fully contact with the heating surface and improve the evaporation efficiency. However, this evaporation method is prone to accumulate scale on the inner wall of the pipe; 2. Multi-effect distilled water machines usually include multiple effect bodies connected in series. After the raw water is boiled and condensed in the first effect body, the distilled water produced will enter the next effect body for further processing. After part of the raw water reaches the boiling point for the first time, it is liquefied through the condensation equipment and enters the next equipment. Some equipment has the problem of pouring all the collected condensed water into the next processing chamber. However, in actual production, the quantitative raw water will be increased and combined with the first effect body. The water vapor after the second liquefaction is mixed, which can buffer the impact of water quality fluctuations on the quality of the final distilled water to a certain extent. If this amount of fusion cannot be achieved, the pH of the distilled water will deviate from the ideal range; 3. During the boiling process, as the water temperature rises to the boiling point, the water will change from liquid to gas. In this process, a large amount of water vapor will be formed. At the same time, the solubility of the gas originally dissolved in the water (such as air, etc.) will decrease when the temperature rises, and bubbles will also form. When the water vapor flows to the condensation area, the bubbles mixed in it will also be brought to the condensation area. The thermal conductivity of the bubbles is poor. When the bubbles enter the condensation area, a layer of air film will be formed on the surface of the condenser tube, which will prevent the water vapor from fully contacting it, thereby reducing the condensation effect and prolonging the processing time. It cannot meet people's usage needs very well. Summary of the invention

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

[0018] Beneficial effects:

[0019] This multi-effect distilled water machine with adjustable water output used in veterinary drug manufacturing uses a metal seal to evenly heat the raw water, avoiding the formation of local high-temperature areas. It can evenly distribute heat in the main part of the water, improving heat utilization efficiency. This uniform heating method reduces the conditions for scale formation, and the first boiler, the second boiler and the metal seal chamber are relatively independent, making it easier to clean scale, reducing the difficulty and cost of equipment maintenance. Unlike traditional falling film evaporators, scale is easily formed on the inner wall of the pipe and is difficult to clean.

[0020] The multi-effect distilled water machine with adjustable water production used for veterinary drug manufacturing has an additional stirring piece. Its arc-shaped and curved blades can evenly stir the raw water to avoid local overheating to produce a large number of bubbles, and can break up the small bubbles that have been formed, effectively reducing the number of bubbles entering the condensation area. The structural distribution of the condenser tubes in the first processing chamber and the second processing chamber gradually narrows from bottom to top and matches the direction of steam movement, which can allow water vapor to pass through and contact the condenser tubes fully and smoothly. At the same time, the condenser tubes are connected to the external cooler to form a stable heat exchange channel to ensure efficient condensation.

[0021] The multi-effect distilled water machine with adjustable water production used for veterinary drug manufacturing has a raw water filter element arranged inside a pipe that directly transports raw water. The raw water is filtered when it enters the equipment, and a variety of filter elements are installed inside the first filter element mounting groove to achieve progressive filtration 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, and the various components such as the first block and the second block are reasonably designed, which is conducive to steam transmission and condensate collection.

[0022] This multi-effect distilled water machine with adjustable water production used in veterinary drug manufacturing combines a drainage tube with a pipe with a flow meter and sets a volume control plate. The flow meter is used to preliminarily monitor the flow rate, and the pressure sensor at the bottom of the volume control plate senses the weight of the distilled water in real time. The dual monitoring and control mechanism can accurately control the amount of distilled water extracted, which is of great significance in fields with strict requirements on the quality and dosage of distilled water.

[0023] The multi-effect water distiller with adjustable water production used for veterinary drug manufacturing has a vacuum machine connected to the first processing chamber and the second processing chamber to form a negative pressure environment, which promotes the rapid flow and condensation of high-temperature water vapor driven by the pressure difference, thereby improving the heat exchange efficiency and distillation speed. The second filter element installation groove at the front end of the guide tube is equipped with a ceramic filter element, which can effectively intercept impurities carried in the water vapor and improve the purity of the distilled water.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] See also Figures 1 to 7 The present invention provides a technical solution: a multi-effect distilled water machine with adjustable water production for veterinary drug manufacturing, comprising a first boiler 1, a first processing chamber 2 is installed at one end of the outer wall of the first boiler 1, the bottom of the first processing chamber 2 is connected to the top of the second boiler 3 through a pipeline, a second processing chamber 4 is installed at one end of the second boiler 3, a distilled water collecting tank 5 is installed below the second processing chamber 4, the first boiler 1 and the first processing chamber 2 and the second boiler 3 and the second processing chamber 4 are connected through a guide pipe 6, condensation pipes 7 are installed inside the first processing chamber 2 and the second processing chamber 4 respectively, and control disks 8 are installed below the condensation pipes 7 respectively, and the control disks 8 are rotatably connected to the first processing chamber 2 and the distilled water collecting tank respectively. 5, the first boiler 1 and the second boiler 3 are respectively provided with a metal sealed chamber 9 and a stirring member 10, the stirring member 10 is distributed along the periphery of the axial point of the metal sealed chamber 9, the first boiler 1, the second boiler 3 and the distilled water collecting tank 5 are integrally connected through the frame, the first processing chamber 2 and the second processing chamber 4 are fixed to the top of the frame through a hanger, the distilled water collecting tank 5 is located on the side of the frame, and a vacuum machine 11 is installed inside the frame corresponding to the lower part of the first boiler 1 and the second boiler 3, the top of the second boiler 3 is connected with a water distribution tank 12 through a pipeline, the first processing chamber 2 is located between the first boiler 1 and the water distribution tank 12, a pipeline is opened on the top of the water distribution tank 12, and a raw water filter 13 is threadedly connected to the inner wall of the pipeline.

[0036] The stirring member 10 includes a driving gear 1001, a driven gear 1002 and a blade 1003. The driving gear 1001 and the driven gear 1002 are respectively rotatably connected to the bottom of the outer wall of the first boiler 1 and one side of the outer wall of the second boiler 3, which are arranged correspondingly thereto. The driven gear 1002 extends through the shaft at its axis center to the inside of the first boiler 1 and the second boiler 3, which are arranged correspondingly thereto, and the blade 1003 is respectively rotatably connected to the inside of the first boiler 1 and the second boiler 3.

[0037] In this embodiment, Figure 1 and Figure 2 As shown, the first boiler 1 and the second boiler 3 are vertically distributed, and the second boiler 3 is smaller than the first boiler 1, and the first boiler 1 and the second boiler 3 are both made of double-layer metal material, and a heat-insulating layer is installed between the inner and outer layers; the layout between the first boiler 1, the second boiler 3 and the first processing chamber 2 reduces the bending and length of the pipeline, which is conducive to the rapid transmission of steam and improves the distillation efficiency, and the heat-insulating layer is installed in the middle of the double-layer metal material, which can not only effectively prevent heat from being lost from the inside to the outside, but also the outer surface temperature will not be too high, which greatly reduces the risk of being scalded by accidental contact with the surface of the equipment for personnel operating around the equipment.

[0038] In this embodiment, Figure 3 and Figure 4 As shown, the raw water filter element 13 is composed of three groups of first filter element installation grooves 1301 of the same specifications that are closely fitted together, and the axis centers of the tops of the two groups of first filter element installation grooves 1301 located at the bottom are provided with docking joints 1302, and the axis centers of the bottoms of the two groups of first filter element installation grooves 1301 located at the top are provided with notches for threaded connection with the docking joints 1302, and at the same time, the inner wall of the pipeline opened by the top cover of the first boiler 1 is threadedly connected with the raw water filter element 13, and the specifications of the raw water filter element 13 located above the first boiler 1 are consistent with the inner diameter of the pipeline opening at the top of the first boiler 1; the raw water filter element 13 is arranged inside the pipeline that directly transports the raw water, so that the raw water can be filtered as soon as it enters the equipment, which This can prevent impurities from entering subsequent core components such as the boiler and reduce the accumulation of impurities inside the equipment, thereby reducing impurities such as scale generated during the boiling process, thereby improving the efficiency and quality of distillation. The first filter element installation grooves 1301 are connected to the inner wall of the pipe through threads, and the upper and lower parts can also be fitted together by using the threaded structure of the docking joint 1302. The structure of the docking joint 1302 provides a gripping point, which provides convenience for installation and disassembly. At the same time, PP cotton, activated carbon, and ultrafiltration membrane filter elements are installed from top to bottom in the first filter element installation groove 1301, realizing a gradual progression from coarse filtration to fine filtration. The synergistic effect of the three filter elements enables the best raw water filtration effect.

[0039] In this embodiment, Figure 1 , Figure 2 ,and Figure 3 As shown, the metal sealed cavity 9 is welded to the axis point of the inner bottom wall of the first boiler 1 and the axis point of one end of the second boiler 3, respectively, and the metal sealed cavity 9 is a cavity and a plurality of groups of electric heating tubes are distributed in the cavity, and the outer walls of the first boiler 1 and the second boiler 3 are both installed with a temperature controller 14 electrically connected to the electric heating tube; compared with the treatment method of the currently commonly used falling film evaporator, due to the contact method between the water film and the heating surface and the local temperature difference, scale is easily formed on the inner wall of the pipeline, and the metal sealed cavity 9 is uniformly heated in the middle of the raw water, which avoids the formation of local high temperature areas and reduces the conditions for scale formation. Even if a small amount of scale is generated, since the first boiler 1 and the second boiler 3 and the metal sealed cavity 9 are all relatively independent structures, compared with the scale cleaning of the inner wall of the pipeline in the falling film evaporator, the operability is stronger, and it is more convenient to clean the scale in an open environment, and there is no need to disassemble and clean the complex pipeline system, which reduces the difficulty and cost of equipment maintenance.

[0040] In this embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the blades 1003 are distributed in a ring shape along the axis of the metal sealed cavity 9, and a first stopper 15 is provided at one end of the inner wall of the second boiler 3, and the first stopper 15 is relatively distributed with the metal sealed cavity 9 distributed in the second boiler 3; because high-temperature water will produce bubbles, when bubbles enter the condensation zone with water vapor, impurities may be adsorbed on the bubble surface, and when the bubbles enter the condensation zone and burst, these impurities will enter the distilled water, and at the same time, when the bubbles enter the cold zone, they will also form a layer of air film on the surface of the condenser 7, which hinders the water vapor from fully contacting it, thereby reducing the condensation effect and prolonging the processing time. By adding a stirring member 10, its blades 1003 are arc-shaped and have curvature. During the rotation process, it can cover a larger stirring area, and it rotates at an equiangular distribution outside the axis of the metal sealed cavity 9, so that the raw water is evenly stirred, which can avoid overheating of water in a local area and generate a large number of bubbles, and for small bubbles that have already formed, the movement of the water flow during the stirring process can break up these bubbles, thereby effectively reducing the bubbles from entering the condensation zone with water vapor.

[0041] In this embodiment, Figure 2 , Figure 5 and Figure 7As shown, the first processing chamber 2 is distributed vertically, and the second processing chamber 4 is distributed obliquely, and the condenser 7 is spirally coiled, one end of which is wider and gradually narrows along the extension direction of the tube body. The condenser 7 in the first processing chamber 2 is distributed vertically, and its wider end is located above the connecting pipe port where the first processing chamber 2 is connected to the guide pipe 6, and the condenser 7 in the second processing chamber 4 is distributed obliquely, and its narrower end is located at the lowest end point of the surface of the second processing chamber 4, and one end of the tube body at the upper and lower ends of the condenser 7 penetrates and extends to the outside of the first processing chamber 2 and the second processing chamber 4 respectively, and at the same time, the tube mouths of the condenser 7 corresponding to the outside of the first processing chamber 2 and the second processing chamber 4 are covered with sealing rubber pads; when water vapor enters the first processing chamber 2 from the first boiler 1, the water vapor itself has an upward movement tendency due to heat, and the structure of the condenser 7 gradually narrowing from bottom to top matches the rising movement direction of the steam. When water vapor flows into the first processing chamber 2 from the first boiler 1, considering that the water vapor can pass through the condenser 7 smoothly and contact it, its wider entrance can accommodate more steam. As the steam flows upward, the tube diameter gradually decreases, and the steam is gradually compressed and guided in this process. As the steam condenses into water in contact with the gradually narrowing condenser 7, the condensed water will flow downward along the condenser 7 under the action of gravity. The condenser 7 in the second processing chamber 4 has the same principle, and the tube bodies at the upper and lower ends of the condenser 7 pass through the box in which it is located and can be connected to the external cooler, ensuring a stable and direct heat exchange channel, so that the cooling medium can circulate efficiently in the condenser 7, take away the heat of the water vapor, and achieve rapid condensation. The sealing rubber pad can effectively fill the small gap between the condenser 7 and the external interface of the processing chamber opposite to it, effectively ensuring the sealing.

[0042] In this embodiment, Figure 6 and Figure 7As shown, a second stopper 16 is provided inside the second processing chamber 4 corresponding to the narrower end of the condensing tube 7 therein, and the edges of the first stopper 15 and the second stopper 16 are both arc-shaped and respectively fit the inner walls of the second boiling vessel 3 and the second processing chamber 4 corresponding thereto, and the tops of the first stopper 15 and the second stopper 16 are both inclined cross-sectional shapes; firstly, since the second boiling vessel 3 is arranged horizontally, water may be distributed too widely in the second boiling vessel 3 without restriction, and the existence of the first stopper 15 can prevent water from being distributed to too many areas, so that the water is always maintained in the metal seal. The periphery of the heat source of cavity 9 can ensure that the heat is concentrated in the main part of the water. When the water vapor contacts the condenser 7 which is also obliquely distributed in the second processing chamber 4, the generated condensed water will eventually fall through the narrower end of the condenser 7 under gravity and flow into the distilled water collection tank 5 through the drainage tube 17. If there is no second stopper 16 to block it, splashing may occur due to the gravity of the condensed water and the collision with the bottom of the second processing chamber 4. The existence of the second stopper 16 not only reduces the occurrence of splashing condensed water, but also guides it into the drainage tube 17 to achieve docking with the distilled water collection tank 5.

[0043] In this embodiment, Figure 2 , Figure 5 and Figure 7 As shown, the bottom of the second treatment chamber 4 is provided with a drainage tube 17 which is also inclined therewith, and the bottom of the second treatment chamber 4 is penetrated by a strip-shaped notch which is connected to the drainage tube 17, and the bottom of the lowest side of the end point of the drainage tube 17 is connected to the top of the distilled water collection tank 5 through a pipeline, and at the same time, the bottoms of the first treatment chamber 2 and the distilled water collection tank 5 are both funnel-shaped structures, and the control disk 8 is respectively connected to the funnel-shaped cavities of the first treatment chamber 2 and the distilled water collection tank 5 through a servo motor, and the top of the control disk 8 is a concave cavity in a circular rim, and one end of the circular rim is rotatably connected to a movable panel, and at the same time A pressure sensor is provided at the bottom of the quantity control disk 8; by combining the drainage tube 17 with a pipe with a flow meter and subsequently setting the quantity control disk 8, the control of the amount of distilled water extraction is achieved. The flow meter can preliminarily monitor the flow entering the distilled water collection tank 5, and the pressure sensor at the bottom of the quantity control disk 8 can sense the weight of the distilled water on the surface of the quantity control disk 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 single flow meter. In fields such as veterinary drug manufacturing that have strict requirements on the quality and dosage of distilled water, it can ensure that the amount of distilled water extracted each time is accurate.

[0044] In this embodiment, Figure 1 and Figure 2As shown, the guide tube 6 is trumpet-shaped, and the guide tube 6 located between the first boiler 1 and the first processing chamber 2 has its larger pipe opening side threadedly connected to the inner wall of the through hole opened correspondingly on the outer wall of the first boiler 1, and the guide tube 6 located between the second boiler 3 and the second processing chamber 4 has its larger pipe opening side threadedly connected to the inner wall of the through hole opened through the cover body of one end of the second boiler 3, and at the same time, the inner wall of the larger pipe opening side of the guide tube 6 is threadedly connected with the second filter element installation groove 18; the guide tube 6 is an important component for conveying water vapor, and its shape reduces the resistance of water vapor conveying, provides a spacious channel for water vapor, so that it can naturally and smoothly transition to the collection device, and the inner wall of the front end thereof is threadedly connected with the second filter element installation groove 18, which is provided with a ceramic filter element, and when the water vapor passes through the ceramic filter element installed in the second filter element installation groove 18, these tiny pores can effectively intercept the 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, Figure 2 As shown, the first processing chamber 2 and the second processing chamber 4 are both connected to the vacuum machine 11 through a pipeline, and the outer walls of the first processing chamber 2 and the second processing chamber 4 are both installed with a pressure gauge 19; when the vacuum machine 11 is connected to the first processing chamber 2 and the second processing chamber 4 and works, the air in the chamber will be extracted to reduce the air pressure in the chamber, forming a negative pressure environment. Based on the principle of gas flow, the gas always flows from the high-pressure area to the low-pressure area. In this case, the high-temperature water vapor in the first boiler 1 and the second boiler 3 will flow to the first processing chamber 2 and the second processing chamber 4 with lower pressure driven by the pressure difference, and then the water vapor can condense faster on the condenser 7, thereby improving the heat exchange efficiency and speeding up the entire distillation process.

[0046] In summary, the multi-effect distilled water machine with adjustable water production for veterinary drug manufacturing, when in use, connects the first boiler 1 and the pipes on the top cover of the water distribution tank 12 to the external water supply equipment, and monitors the incoming raw water flow in real time according to the flow meter (LDG-SUP) arranged on the pipeline. When the raw water passes through the pipeline, it is in full contact with the raw water filter element 13, and the first filter element installation groove 1301 gradually performs multiple filtering treatments on the raw water. As the raw water continues to flow in, the filtered raw water enters the first boiler 1 and the second boiler 3. After the flow meter detects the preset parameters, it transmits the signal to the control system. After receiving the signal from the electromagnetic flow meter, the control system sends a command to the electromagnetic valve electrically connected to the flow meter, and the electromagnetic valve (4V2 10-08) is closed to cut off the fluid channel, thereby ensuring the quantitative amount of liquid inside the first boiler 1 and the second boiler 3. At this time, the power supply located on one side of the first boiler 1 is turned on, and the electric heating tube in the metal sealing cavity 9 inside it heats the raw water under the control of the temperature controller 14. At the same time, the active gear 1001 drives the driven gear 1002 to rotate under the drive of the servo motor, so that the blade 1003 stirs the raw water to ensure that the raw water is heated evenly, avoid local overheating to produce a large number of bubbles, and break up the small bubbles that have been 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 through the pipeline using the vacuum machine 11 (GDZK-400), and the guide pipe 6 needs to be closed. The valve is arranged on the first treatment chamber 2 and the second treatment chamber 4, and the pressure gauge 19 on the surface of the first treatment chamber 2 and the second treatment chamber 4 can monitor the internal pressure value in real time, and the temperature can be monitored in real time through the temperature controller 14 (STC-200+). The operator can ensure that the liquid temperature in the first boiler 1 is kept within the optimal distillation temperature range. When the preset parameters are reached, the guide pipe 6 is based on the principle of the solenoid valve of the pipeline above the first boiler 1. Under the command of the control body, the valve opens. Based on the principle of gas flow, the gas always flows from the high-pressure area to the low-pressure area. The water vapor will flow into the first treatment chamber 2 through the guide pipe 6 between the first boiler 1 and the first treatment chamber 2. The filter element of the second filter element installation 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 The water vapor itself has an upward movement tendency due to heat. As the steam flows upward, the tube diameter gradually decreases. The steam is gradually compressed and guided in this process. As the steam contacts the gradually narrowing condenser tube 7 and condenses into water, the condensed water will flow downward along the condenser tube 7 under the action of gravity and fall into the concave cavity on the surface of the control plate 8 in the first processing chamber 2. The pressure sensor will monitor the weight change in real time. The control plate 8 is connected to the first processing chamber 2 through a servo motor and can perform precise angle adjustment according to the data of the pressure sensor. As the condensed water continues to accumulate, when the weight reaches the preset parameter value, the control plate 8 is flipped under the drive of the servo motor, so that the movable panel opens a certain angle to allow the condensed water to flow out into the funnel-shaped cavity below.At this time, according to the flow meter and solenoid valve set in the pipeline between the bottom of the first processing chamber 2 and the second boiler 3, the condensed water collected in the first processing chamber 2 is transported to the inside of the second boiler 3 through the preset device and fully mixed with the raw water that has entered in advance through the water distribution tank 12, and the mixed water in the second boiler 3 is heated again in a manner consistent with the boiling process in the first boiler 1. Due to the structure of the first stopper 15 inside it, the diffusion of the water is effectively avoided. The temperature controller 14 monitors the temperature in real time. When the preset parameters are reached, the guide pipe 6 is based on the principle of the solenoid valve of the pipeline above the first boiler 1. Under the command of the control body, the valve is opened, and the water vapor in the second boiler 3 is discharged to the second processing chamber 4 through the guide pipe 6 on one side thereof. The water vapor is then collected and fully contacted with the condenser tube 7 inside the second treatment chamber 4. Due to the inclined structure of the condenser tube 7, the water vapor converted into condensed water is also collected into the drainage tube 17 through the through hole below the second treatment chamber 4 under gravity. The inner wall of the drainage tube 17 is coated with a polytetrafluoroethylene coating, which can make the condensed water flow on its inner wall with minimal resistance. Finally, the water enters the distilled water collection tank 5 through the through hole between the drainage tube 17 and the distilled water collection tank 5 and is collected into the control plate 8. When the operator extracts the water, he only needs the external flow meter and solenoid valve of the distilled water collection tank 5 to accurately extract the required amount of water. At the same time, the bottom of the first boiler 1 and the second boiler 3 are both provided with drainage ports, and the excess waste water can be discharged by opening the drainage ports.
