Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical process technology, specifically a pure steam generator with an automatic drain valve. Background Technology

[0002] Pure steam generators are specialized equipment that emerged to meet the demands of industries requiring high cleanliness. Their core purpose stems from the stringent purity requirements of steam in fields such as medical, pharmaceutical, food and beverage, and bioengineering. Ordinary industrial steam often contains moisture, impurities, minerals, and chemical additives, failing to meet the core standard of "no contaminant residue" in these fields. For example, the pharmaceutical industry must comply with GMP (Good Manufacturing Practice), the food industry must adhere to food safety regulations, and the medical field requires steam to produce no harmful byproducts during sterilization. To fill this gap, pure steam generators utilize special heating, separation, and purification technologies to transform incoming water (usually purified water or water for injection) into high-purity steam free of solid impurities, non-volatile contaminants, and microorganisms. Their emergence not only solves the production and sterilization pain points of high-cleanliness industries but also becomes a key piece of equipment for ensuring drug quality, food safety, and the safety of medical procedures, serving as crucial technical support for the "clean production" concept in modern industrial systems.

[0003] However, the current pure steam generator does not have an active decontamination and drainage structure inside. Dirt tends to accumulate at the bottom of the generator in areas far from the drain outlet, requiring internal cleaning and maintenance every so often, which affects the efficiency of obtaining distilled water.

[0004] To address this issue, the present invention provides a pure steam generator with an automatic drain valve. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pure steam generator with an automatic drain valve, comprising: A pure steam generator structure, wherein the pure steam generator structure includes a pure steam generator body; Inside the evaporation chamber of the pure steam generator body, on the adjacent and opposite sides of the drain pipe located at the lower right center of the pure steam generator body, side scrapers and main scrapers are respectively arranged along the bottom surface of the evaporation chamber. The inclined surface of the side scraper is internally recessed with a racket-shaped sliding groove, and the sliding groove is movably connected to the two ends of the main scraper under the sliding constraint cooperation with the connecting sliding arms integrally set at both ends of the main scraper. The center position inside the main scraper is equipped with a gear that rotates with a bearing, and the two ends of the gear pass through the main scraper and are fixedly driven by the shaft of the motor that is connected to a screw rod located on one side of the inclined surface of the main scraper and a coupling on the opposite side of the screw rod.

[0007] Preferably, the sides of both the main scraper and the side scraper facing the evaporating water source are set as inclined surfaces.

[0008] Preferably, the main scraper has equal-length cuts on both sides near the side scraper, and a high-strength, retractable telescopic scraper sleeve is sealed and fitted at the cut position, so that the main scraper body has the ability to extend and retract with the assistance of the telescopic scraper sleeve.

[0009] Preferably, the upper and lower sides of the gear mesh with a toothed plate that is reciprocating inside the main scraper.

[0010] Preferably, the two toothed plates are respectively inserted into a telescopic scraper sleeve, and the main scraper connected to the telescopic scraper sleeve at the end is fixed, so that under the transmission of the toothed plates by the motor through gears, the centripetal traction of the two ends of the main scraper and the compression of the telescopic scraper sleeve are performed.

[0011] Preferably, the screw rod is positioned directly opposite the drain pipe of the main evaporation chamber of the pure steam generator.

[0012] Preferably, the motor is connected to the output of the electric actuator by bolts, and both the electric actuator and the motor are electrically connected to the main body of the pure steam generator via wiring. Beneficial effects

[0013] This invention provides a pure steam generator with an automatic drain valve. Compared with the prior art, it has the following advantages: (1) The pure steam generator with automatic drain valve, through the inclined structure of the main scraper and the side scraper, the setting of the telescopic scraper sleeve on the main scraper and the connecting slide arm, enables the main scraper to extend and retract with the assistance of the telescopic scraper sleeve, and can drive the side scraper to move in coordination through the racket-shaped slide groove of the connecting slide arm and the side scraper. The inclined surfaces of both push the deposited dirt at the bottom of the evaporation chamber, especially in the area far from the drain outlet, to the drain pipe, which solves the problem of easy dirt accumulation at the bottom of the existing pure steam generator and the need for frequent manual cleaning and maintenance, and effectively improves the efficiency of obtaining distilled water.

[0014] (2) The pure steam generator with automatic drain valve, through the meshing transmission structure of motor, gear and toothed plate and the setting of screw rod facing the drain pipe, enables the motor to drive the gear to drive the toothed plate to pull the two ends of the main scraper to retract inward, and at the same time drive the screw rod to rotate synchronously. The screw rod can actively send the sewage pushed to the drain pipe into the pipeline, which not only further improves the sewage discharge efficiency, but also avoids the situation of sewage accumulating and blocking at the drain pipe, ensuring the stability and smoothness of the sewage discharge process.

[0017] 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.

[0018] Please see Figures 1-4 A pure steam generator with an automatic drain valve, comprising: The pure steam generator structure 1 includes an evaporation system for generating steam, a separation and purification device for removing impurities, a control system for regulating operating parameters, and auxiliary components such as water supply and drainage. The pure steam generator structure 1 includes a pure steam generator body 11; Inside the evaporation chamber of the pure steam generator body 11, a side scraper 14 and a main scraper 13 are slidably mounted on the adjacent and opposite sides of the drain pipe located at the lower right center of the pure steam generator body 11, respectively, along the bottom surface of the evaporation chamber. Both the main scraper 13 and the side scraper 14 have beveled sides facing the evaporating water source. The main scraper 13 has equal-length cuts on both sides near the side scraper 14, and high-strength, retractable telescopic scraper sleeves 131 are sealed at the cut locations, allowing the main scraper 13 to extend and retract with the assistance of the telescopic scraper sleeves 131. A racket-shaped groove is recessed within the bevel of the side scraper 14, and this groove, in conjunction with the sliding constraint of the connecting sliding arms 132 integrally mounted at both ends of the main scraper 13, allows the side scraper 14 to move between the two ends of the main scraper 13. A gear 122 is rotatably mounted at the center of the main scraper 13, cooperating with a bearing, and both ends of the gear 122 pass through the main scraper. The blade 13 is fixed to the shaft of the motor 121, which is connected to the screw rod 123 located on one side of the inclined surface of the main scraper 13 and to the shaft of the motor 121 connected to the screw rod 123 on the opposite side by a coupling. The upper and lower sides of the gear 122 mesh with the toothed plates 133 reciprocating inside the main scraper 13. The two toothed plates 133 are respectively inserted into a telescopic scraper sleeve 131 and fixed to the main scraper 13 connected to the telescopic scraper sleeve 131 at their ends. Thus, the motor 121 drives the main scraper 13 through the gear 122. Under the transmission of the two toothed plates 133, the centripetal traction of the two ends of the main scraper 13 and the compression of the telescopic scraper sleeve 131 are performed. The screw rod 123 is set in the drain pipe of the evaporation chamber of the pure steam generator body 11. The motor 121 is connected to the output of the electric push rod 12 by bolts. Both the electric push rod 12 and the motor 121 are electrically connected to the pure steam generator body 11 through lines. The main body of the electric push rod 12 is isolated and assembled inside the pure steam generator body 11.

[0019] After the control system of the pure steam generator body 11 triggers the sewage discharge, the electric push rod 12 drives the motor 121 and the main scraper 13 to move as a whole. The main scraper 13 slides along the racket-shaped slide groove of the side scraper 14 via the connecting slide arm 132 to complete the movement guidance. Then the motor 121 starts, and the shaft drives the gear 122 inside the main scraper 13 to rotate, meshing with the toothed plate 133 to make the two ends of the main scraper 13 retract towards the center, synchronously compressing the sealed telescopic scraper sleeve 131. The main scraper 13 drives the side scraper 14 through the connecting slide arm 132 to move towards it along the slide rail on the inner wall of the evaporation chamber of the pure steam generator body 11, realizing the coordinated action of the main scraper 13 and the side scraper 14. The inclined surfaces of the two work together to push the dirt at the bottom of the evaporation chamber towards the sewage discharge pipe. At the same time, the screw rod 123 on the shaft of the motor 121 rotates synchronously, actively sending the dirt at the pipe opening into the sewage discharge pipe, improving efficiency and preventing blockage.

[0020] In summary, through the inclined structure of the main scraper 13 and the side scraper 14, the telescopic scraper sleeve 131 on the main scraper 13, and the connecting sliding arm 132, the main scraper 13 can extend and retract with the assistance of the telescopic scraper sleeve 131. Furthermore, the connecting sliding arm 132, in conjunction with the racket-shaped sliding groove of the side scraper 14, drives the side scraper 14 to move collaboratively. The inclined surfaces of both push the deposited dirt at the bottom of the evaporation chamber, especially in areas far from the drain outlet, towards the drain pipe. This effectively solves the problem of easy dirt accumulation at the bottom of existing pure steam generators, requiring frequent manual cleaning and maintenance. This improves the efficiency of obtaining distilled water. Through the meshing transmission structure of the motor 121, gear 122, and toothed plate 133, and the setting of the screw rod 123 facing the sewage pipe, the motor 121 can drive the gear 122 to drive the toothed plate 133 to pull the two ends of the main scraper 13 to retract inward. At the same time, it drives the screw rod 123 to rotate synchronously. The screw rod 123 can actively send the sewage pushed to the sewage pipe opening into the pipe, which not only further improves the sewage discharge efficiency, but also avoids the situation of sewage accumulating and blocking at the sewage pipe opening, ensuring the stability and smoothness of the sewage discharge process.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Working principle: During operation, after the control system of the pure steam generator body 11 triggers the sewage discharge process, the electric actuator 12 first provides power to drive the motor 121 and the main scraper 13 connected to it to move as a whole. The main scraper 13 slides along the racket-shaped groove on the surface of the side scraper 14 through the connecting sliding arms 132 at both ends towards the sewage discharge pipeline, realizing basic movement guidance. Then the motor 121 starts, and its shaft drives the gear 122 inside the main scraper 13 to rotate through the coupling. The gear 122 meshes with the toothed plates 133 on the upper and lower sides, causing the toothed plates 133 to move towards the center of the main scraper 13, thereby pulling the two ends of the main scraper 13 to retract towards the center. At this time, the telescopic scraper sleeve 131 sealed at the disconnection point of the main scraper 13 is compressed synchronously. Because the two ends of the main scraper 13 are connected to the side scraper 14 through the connecting sliding arms 132, the main scraper 13 moves towards the center of the main scraper 13. The trough maintains a sliding connection. During the retraction of the main scraper 13 (compression of the telescopic scraper sleeve 131), it will simultaneously drive the side scraper 14 to move along the inner wall (with slide rail constraint) of the evaporation chamber of the pure steam generator body 11 towards the main scraper 13, forming a coordinated approaching action of the main scraper 13 and the side scraper 14. During this process, the inclined surfaces of the main scraper 13 and the side scraper 14 facing the evaporation water source work together to push the dirt deposited at the bottom of the evaporation chamber towards the drain pipe. At the same time, the screw rod 123, which is fixedly connected to the shaft of the motor 121, rotates synchronously with the motor 121. When the dirt is pushed to the drain pipe opening by the main scraper 13 and the side scraper 14, the rotating screw rod 123 directly and actively transports the dirt, pushing it into the drain pipe, which not only improves the drain efficiency but also effectively avoids the problem of dirt accumulating and clogging at the drain pipe opening.
