[0002] An evaporator is a type of heat exchange device with phase change, which can use heating to concentrate a solution or precipitate a substance from a solution. Generally, an evaporator is mainly composed of a heating chamber and an evaporation chamber. At present, most pharmaceutical production and processing require the use of an evaporator to evaporate and concentrate the drug solution, thereby improving the purity and quality of the drug. For example, the Chinese patent application number is 202321589709.0, which is an evaporator for drug production. The evaporator generates steam through a steam component to heat and evaporate the drug in the evaporation ball. The drug vapor is introduced into the annular glass ball along the steam guide pipe. The annular structure of the annular glass ball increases the contact area with the air. The cold and liquefied drug is discharged along the discharge pipe, thereby realizing rapid natural cooling of the drug vapor. However, the existing evaporator has a poor evaporation efficiency for drugs, and the discharged steam is not recycled, resulting in a waste of heat and increased cost investment.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use: 1. An efficient circulating evaporation mechanism is set up. Through the cooperation of the liquid inlet pipe, the guide pipe, the preheating plate and the liquid medicine replenishing pipe, the liquid medicine is conveniently transported, so that the liquid medicine gathers in the temporary storage chamber, and then pushes the floating plate up, and flows along the gap between the evaporation pipe and the internal heating pipe, which reduces the thickness of the liquid medicine when it flows, facilitates the high-temperature steam inside the evaporation chamber to heat the liquid medicine, and improves the evaporation efficiency; Part of the steam inside the evaporation chamber is transported to the steam gathering plate inside the temporary storage chamber of the liquid medicine through the connecting elbow, and is transported to the inside of the steam gathering plate in the concentrated liquid storage chamber along the internal heating pipe, so that the steam heats the inside of the liquid medicine inside the evaporation pipe through the internal heating pipe, further improving the evaporation efficiency; The evaporated and concentrated medicine liquid is stored at the bottom of the concentrated liquid storage chamber through the evaporation pipe, and the generated steam is gathered at the top of the concentrated liquid storage chamber, and then discharged into the steam recovery tank through the horizontal pipe, and the moisture inside the recovered steam is separated by the cooperation of the trapezoidal cylinder, the rotating motor, the rotating rod, the exhaust fan blades and the rotating blades, and stored at the bottom of the steam recovery tank, while the steam with the moisture removed enters the extension cylinder and is transported to the steam gathering plate inside the medicine liquid temporary storage chamber through the secondary steam input pipe, so that the recovered steam heats the medicine liquid inside the evaporation pipe through the internal heating pipe, thereby improving the utilization rate of resources and the efficiency of heating evaporation, and at the same time, it can reduce the amount of steam transported by the heat source inlet pipe and reduce resource consumption; The steam is sent into the preheating tank through the first collecting pipe to preheat the medicine liquid passing through the guide pipe and the preheating plate, thereby increasing the temperature of the medicine liquid and improving the efficiency of subsequent evaporation and concentration of the medicine liquid. Then the steam is discharged into the heating cylinder again through the second collecting pipe to preheat the water passing through, thereby improving the efficiency of subsequent water evaporation, so that resources can be fully utilized and waste can be reduced.

[0015] A recycling mechanism is provided, and water is sent into the steam generator through the cooperation of the water inlet pipe, the shunt pipe and the water supply pipe, so that the heating rod heats the water inside the steam generator to evaporate the water and generate steam. At the same time, the spiral baffle and the defoaming net cooperate to filter and block the rising steam, so that the water condenses into water droplets and reduces the moisture content of the steam. Then, the steam is pressurized and transported through the cooperation of the fixed cylinder, the steam booster pump and the output pipe, so that the steam enters the evaporation chamber inside the evaporation concentration tank through the heat source inlet pipe for heating and temperature increase, thereby ensuring the supply of heat source and meeting the demand for evaporation of the liquid medicine. The hot water inside the steam recovery tank pushes the float, the slide bar and the water baffle plate to rise, separate from the baffle ring, release the seal, make the vertical pipe and the return pipe cooperate, form a connection between the steam recovery tank and the insulation water tank, and facilitate the hot water inside the steam recovery tank to be discharged into the insulation water tank. As the hot water inside the insulation water tank increases, the float ring is pushed up, so that a push rod rises and contacts with the push switch, the solenoid valve is closed, the water pump is started, and the hot water inside the insulation water tank is sent to the steam generator through the pumping pipe, which is convenient for recycling water resources, improves the efficiency of steam generation, and maintains the evaporation effect of the liquid medicine. Through the expansion and contraction characteristics of the tension spring, when the hot water inside the steam recovery tank decreases, the water baffle plate is pushed down and fits with the baffle ring to prevent the liquid level from dropping too low, prevent steam from being discharged from the vertical pipe and the return pipe, and reduce waste; The water pressure inside the steam generator pushes the insulation sealing plate down to release the seal of the overflow tank, so that the excess water can be discharged into the insulation water tank through the inner cylinder, thereby preventing the steam generator from overflowing due to excessive water. At the same time, the expansion and contraction characteristics of the supporting spring can timely push the insulation sealing plate up and reset, thereby sealing the overflow tank and reducing heat loss. In addition, when the hot water inside the insulated water tank is drained, the floating ring drops, pushing the other push rod down, releasing the push switch, turning off the water pump, opening the solenoid valve, and resupplying water to the steam generator through the water supply pipe. At the same time, the waste heat of the discharged steam is used to heat the water through the heating cylinder and the diversion pipe to improve the efficiency of subsequent evaporation.

[0016] In summary, the discharged steam is recovered through the cooperation of the high-efficiency circulating evaporation mechanism and the recovery and recycling mechanism, so that the residual heat is reused, the efficiency of the evaporation of the liquid medicine is improved, and the waste of heat source is reduced. At the same time, in the process of steam recovery and utilization, the moisture in the mirror steam is separated, which is convenient for the moisture to affect the effect of subsequent evaporation. In addition, in the steam recovery process, the hot water generated is also recycled, which improves efficiency, reduces consumption and saves costs when heating to generate steam in the subsequent time.

[0022] The working principle and use process of the present invention are as follows: first, water is sent into the steam generator 402 through the cooperation of the water inlet pipe 405, the shunt pipe 404 and the water supply pipe 403, and then the heating rod 407 on the gasket ring 406 is started to heat the water in the steam generator 402, so that the water boils and evaporates to generate steam, and then the steam rises along the steam generator 402, passes through the cooperation of the spiral baffle 410 and the defoaming net 408, and the moisture in the steam is blocked, so that the moisture condenses into small water droplets and drips back to the bottom of the steam generator 402, and the steam enters the fixed cylinder 411, and then the steam is pressurized and transported through the cooperation of the steam booster pump 413 and the output pipe 412, forcing the steam to pass through the heat source and enter the pipe 306 to be transported to the evaporation chamber 305 for heating and temperature increase; Next, the liquid medicine to be evaporated is sent into the liquid medicine temporary storage chamber 303 inside the evaporation concentration tank 301 through the cooperation of the liquid inlet pipe 326, the flow guide pipe 325, the preheating plate 324 and the liquid medicine replenishing pipe 304. As the liquid medicine gathers in the liquid medicine temporary storage chamber 303, it pushes the floating plate 312 upward, and the seal of the evaporation pipe 307 is released, so that the liquid medicine flows evenly along the gap between the evaporation pipe 307 and the internal heating pipe 311, and the liquid medicine is heated by the high-temperature steam inside the evaporation chamber 305, so that the residual water in the liquid medicine evaporates, thereby achieving the concentration of the liquid medicine. As the high-temperature steam continuously accumulates inside the evaporation chamber 305, part of the steam after heat exchange is forced to enter the connecting elbow 310, and then be transported to the steam gathering plate 309 inside the liquid medicine temporary storage chamber 303, and then be transported to the steam gathering plate 309 inside the concentrated liquid storage chamber 308 through the internal heating pipe 311, so that the steam heats the inner side of the liquid medicine inside the evaporation pipe 307 through the internal heating pipe 311, further improving the evaporation efficiency; At the same time, the concentrated liquid after the evaporation of the liquid medicine flows along the evaporation pipe 307 into the bottom end of the concentrated liquid storage chamber 308, and the steam generated during evaporation flows along the evaporation pipe 307 and gathers at the top end of the concentrated liquid storage chamber 308, and then is discharged into the steam recovery tank 313 through the cross pipe 314, forcing the steam to contact the outside of the trapezoidal cylinder 315, so that the moisture in the steam condenses into water droplets and falls into the bottom end of the steam recovery tank 313 for storage, while the steam enters the trapezoidal cylinder 315. In addition, the rotating motor 317 drives the rotating rod 318 and the exhaust fan blades 320 to rotate, generating suction, thereby improving the steam inlet. The efficiency of entering the trapezoidal cylinder 315 is improved, and at the same time, the rotating rod 318 drives the rotating blade 319 to rotate together, forcing the steam to rotate inside the trapezoidal cylinder 315, generating centrifugal force, and fitting with the inner wall of the trapezoidal cylinder 315 to gather and form water droplets, and the steam with reduced moisture enters the extension cylinder 316, and is transported to the steam gathering plate 309 inside the liquid medicine temporary storage chamber 303 through the secondary steam input pipe 321, and the steam is recycled through the internal heating pipe 311 to improve the evaporation efficiency. In addition, the amount of steam transported by the heat source inlet pipe 306 can be reduced as needed, reducing the operation of the steam generator 402 and reducing resource consumption; As the steam gathers inside the steam gathering plate 309 in the concentrated liquid storage chamber 308, the steam after heat exchange is transported to the preheating tank 322 through the first collecting pipe 327 for gathering, thereby preheating the liquid medicine passing through the preheating tank 322, improving the efficiency of subsequent evaporation, and then the steam is transported to the heating cylinder 328 again through the second collecting pipe 329 to heat the water passing through, improving the efficiency of subsequent water heating and evaporation, and then discharged through the exhaust pipe 330, improving the reuse rate of resources; Next, the amount of hot water condensed in the steam recovery tank 313 increases, pushing the float 423 upward, forcing the float 423 to pull the water baffle 424 upward through the slide rod 422, separating from the baffle ring 426, releasing the seal on the vertical pipe 421, allowing the vertical pipe 421 to cooperate with the return pipe 420, forming a connection between the steam recovery tank 313 and the insulation water tank 401, facilitating the discharge of the hot water in the steam recovery tank 313 into the insulation water tank 401, and as the hot water in the insulation water tank 401 increases, the steam recovery tank 313 is connected to the insulation water tank 401. The floating ring 430 is pushed upward, forcing the floating ring 430 to push the top rod 431 at the top of the heat preservation water tank 401 upward, contacting the push switch 433, closing the solenoid valve 434, preventing water from entering the steam generator 402 through the water supply pipe 403, and starting the water pump 428 to send the hot water in the heat preservation water tank 401 into the steam generator 402 through the pumping pipe 427, so as to facilitate the recycling of water resources, improve the efficiency of steam generation, and maintain the evaporation effect of the liquid medicine; In addition, when the hot water inside the steam recovery tank 313 decreases, the water baffle plate 424 is pushed down by the expansion and contraction characteristics of the tension spring 425, and fits with the baffle ring 426 to seal the vertical pipe 421, preventing the liquid level from dropping too low, preventing the steam from being discharged from the vertical pipe 421 and the return pipe 420, and reducing waste; Next, when too much water is injected into the steam generator 402, the water pressure increases, pushing the heat preservation sealing plate 417 and the support rod 416 to slide down along the inner wall of the cross plate 415, releasing the seal of the overflow groove 419, and facilitating the discharge of excess water into the heat preservation water tank 401 through the inner cylinder 414, thereby preventing the excess water in the steam generator 402 from overflowing. At the same time, through the expansion and contraction characteristics of the support spring 418, after the excess water is discharged, the heat preservation sealing plate 417 is promptly pushed up and reset to seal the overflow groove 419, thereby reducing the loss of heat. Finally, the water discharged into the insulated water tank 401 is stored, and after the insulated water tank 401 is filled, it is sent back into the steam generator 402 through the pumping pipe 427. In addition, when the hot water in the insulated water tank 401 is emptied, the floating ring 430 descends, pushing the top rod 431 at the bottom of the insulated water tank 401 to descend, and the push switch 433 is released, the water pump 428 is turned off, and the solenoid valve 434 is opened, and water is supplied to the steam generator 402 again through the water supply pipe 403. At the same time, the waste heat of the discharged steam is used to heat the water through the heating cylinder 328 and the shunt pipe 404, thereby improving the efficiency of subsequent evaporation.
