Description

Technical Field

[0001] This application relates to the technical field of distilled water machines, specifically to a distilled water machine with heat recovery function and its usage method. Background Technology

[0002] A water distillation machine is a machine that produces pure water using distillation. It can produce single-distilled or multi-distilled water. In the first distillation, the non-volatile components remain in the container and are removed, while the volatile components enter the initial fraction of the distilled water. Usually, only the middle fraction, which accounts for about 60%, is collected.

[0003] A search revealed Chinese Patent Publication No. CN219977177U, which discloses a waste heat recovery device for a water distiller. The device includes a support frame with a recovery mechanism inside. A filter mechanism is mounted on the surface of the recovery mechanism, which includes a housing fixedly connected to the bottom of the support frame. A rectangular groove is formed at the top of the housing, and a filter screen is inserted into the groove. This waste heat recovery device for a water distiller, through its filter mechanism, filters impurities from the steam, preventing them from being released into the air and polluting the environment. The filter screen is easy to install and remove; when it becomes clogged, it can be easily disassembled and cleaned. The filtered steam, through a second connecting pipe, heats the water inside the container via heat transfer, thus achieving waste heat recovery.

[0004] The aforementioned technologies have the following drawbacks: when the filter screen becomes clogged and needs cleaning, the worker needs to first stop the water distiller and then remove the filter screen for cleaning; after the filter screen is cleaned, it needs to be reinstalled and the water distiller turned on again to continue steam filtration and waste heat recovery; the above operation steps are cumbersome and time-consuming, causing the water distiller to be paused for a long time, which affects the distillation efficiency of the water. Therefore, improvements are needed. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a distillation water machine with heat recovery function and its usage method, thereby improving the distillation efficiency of distilled water.

[0006] In the first aspect, in order to achieve the above objectives, the embodiments of this application specifically adopt the following technical solutions: a distillation water machine with heat recovery function, including a distillation water machine body, a filter and a heat exchange box, the filter including a horizontally arranged filter barrel, a fixed base installed inside the filter barrel, filter plates provided on both the upper and lower sides of the fixed base, the filter plates being slidably abutting against the fixed base, and two through grooves provided on the filter barrel for corresponding filter plates to slide through in the vertical direction;

[0007] When both filter plates are in contact with the fixed seat, the fixed seat and the two filter plates will jointly divide the inside of the filter bucket into a filter chamber and a clean chamber arranged in a semi-cylindrical shape. The filter chamber is connected to the main body of the distillation water machine through an air pipe, and the clean chamber is connected to the heat exchange box through another air pipe.

[0008] Both the filter chamber and the clean chamber are equipped with baffles. One end of the baffle is rotatably connected to the fixed seat via a horizontal shaft, and the other end of the baffle rotates to abut against the inner wall of the filter bucket. This end of the baffle can be flipped to the upper or lower side of the trachea.

[0009] When both baffles are flipped to the upper or lower side of the air pipe at the end away from the fixed seat, if the filter plate slides into the groove at the end facing the fixed seat, the opposite side of the two baffles, the side of the filter plate opposite to the fixed seat, and the inner wall of the filter barrel will together form a cleaning chamber.

[0010] Each impurity removal chamber is connected to an inlet pipe and an outlet pipe. The inlet pipe is connected to the upper part of the impurity removal chamber, and the outlet pipe is connected to the lower part of the impurity removal chamber. A one-way valve is installed on the inlet pipe and is connected to a water pump. The one-way valve is only used by the water pump to supply water into the inlet pipe. A solenoid valve is installed on the outlet pipe.

[0011] Optionally, shovels are installed on both the upper and lower sides of the baffle. The shovels are attached to the inner wall of the filter barrel. When the two baffles are flipped and brought closer together, the two shovels can be used to clamp the filter plate at one end as it slides into the through groove.

[0012] Optionally, the upper and lower parts of the clean chamber are provided with top blocks. The top blocks slide through the filter barrel along their own length direction. The top blocks and the filter barrel are connected to the same spring. The length direction of the spring is the same as the length direction of the top blocks. The end of the top block that extends into the filter barrel is provided with a guide surface for the shovel plate to flip and abut against. The guide surface is inclined.

[0013] It also includes a control unit, which includes a controller and two contact sensors. The contact sensors are mounted on the filter canister and correspond one-to-one with the top block. The contact sensors, water pump and solenoid valve are all coupled to the controller.

[0014] During the flipping process, the shovel can push the top block against the contact sensor through the guide surface. The contact sensor will send a flushing signal to the controller, which will then control the water pump and solenoid valve to open for a specified duration.

[0015] Optionally, a lifting unit is also included, which includes an incomplete gear and two mating gears. The incomplete gear is rotatably connected to the filter barrel, and the incomplete gear can mesh with any one of the mating gears during rotation.

[0016] The gear is connected to the filter barrel via a rotating shaft. A turntable is coaxially connected to the shaft. The turntable corresponds to the filter plate and is connected to a swing rod.

[0017] One end of the swing arm is rotatably connected to the turntable, and the other end of the swing arm is rotatably connected to the filter plate. During the rotation of the turntable, the filter plate will be raised and lowered through the swing arm.

[0018] Optionally, the incomplete gear is coaxially connected to one of the horizontal shafts, and a drive gear is coaxially connected to both horizontal shafts, with the two drive gears meshing with each other;

[0019] As the two baffles flip and move closer to each other, the filter plate located between the two baffles will move away from the fixed seat;

[0020] A worm gear is coaxially connected to one of the horizontal shafts, and a worm is meshed on the worm gear. The worm rotates around its own axis and is connected to the filter barrel.

[0021] Optionally, the filter plate includes an outer frame and an inner plate. The outer frame is slidably embedded in the through groove and is rotatably connected to the swing rod. The inner plate is inserted into the outer frame and has a plurality of filter holes.

[0022] When the two shovels clamp the filter plate together, the inner plate will move to the outside of the filter barrel.

[0023] Optionally, the inner wall of the outer frame is provided with a receiving groove, and an elastic column is installed in the receiving groove. One end of the elastic column is hemispherical and protrudes out of the receiving groove; the side wall of the inner plate is provided with a slot for the hemispherical end of the elastic column to be inserted.

[0024] Secondly, in order to achieve the above objectives, the embodiments of this application specifically adopt the following technical solution: a method of using a distillation water machine with heat recovery function, including the following steps;

[0025] S1. During the filtration process of the steam generated by distilled water, the two baffles will be located at the upper or lower side of the gas pipe at the end away from the fixed seat. The steam generated by the distilled water machine body will enter the filter chamber through one of the gas pipes. After being filtered by one of the filter plates, the steam will enter the clean chamber and enter the heat exchange box through the other gas pipe for waste heat recovery.

[0026] S2. During the cleaning process of the filter plate, the two baffles will flip and approach the filter plate to be cleaned. The steam in the filter chamber will be filtered through the other filter plate. The worker will pull the filter plate to be cleaned so that the end of the filter plate facing the fixed seat sinks into the through groove. At this time, the side of the two baffles facing each other, the side of the filter plate facing the fixed seat, and the inner wall of the filter barrel will together form a cleaning chamber. The water pump will introduce water into the cleaning chamber through the inlet pipe. The water will flush the cleaning chamber, so that the impurities in the cleaning chamber will be discharged through the outlet pipe along with the water.

[0027] The beneficial effects of the embodiments of this application are as follows:

[0028] 1. When the filter plate becomes clogged and needs cleaning, the two baffles will flip and approach the filter plate to be cleaned. During the flipping process, the baffles will drive the scraper to remove impurities adhering to the inner wall of the filter barrel. At the same time, the incomplete gear will drive the rotating shaft and turntable to rotate through the meshing gear. The turntable will drive the filter plate to be cleaned away from the fixed seat through the swing rod. The inner wall of the filter barrel will scrape off the impurities adhering to the surface of the filter plate. Then, the two baffles on the opposite side, the filter plate to be cleaned on the opposite side of the fixed seat, and the inner wall of the filter barrel will together form a cleaning chamber, and the scraper will push the top block to abut against it. The contact sensor sends a flushing signal to the controller, which then controls the water pump and solenoid valve to open. The water pump draws water from an external source and introduces it into the impurity removal chamber through the inlet pipe. Impurities in the impurity removal chamber are discharged through the outlet pipe along with the water. In addition, workers can remove the inner plate of the filter plate to be cleaned for deep cleaning or replacement, while the other filter plate can continue to filter steam. The alternating use of the two filter plates achieves uninterrupted filtration of steam and rapid removal of impurities, thereby improving the distillation efficiency of distilled water.

[0029] 2. During rotation, the incomplete gear can mesh with any mating gear. The mating gear will drive the turntable to rotate via the rotating shaft. During the rotation, the turntable will drive the filter plate to rise and fall via the swing rod. That is, by rotating the incomplete gear, any filter plate can be raised and lowered to clean impurities from the surface of the filter plate.

[0030] 3. During the rotation of the horizontal shaft, the incomplete gear and baffle can be driven to rotate, so that the filter plate to be cleaned can move away from the fixed seat as the two baffles flip and approach each other. This allows the filter plate to be cleaned, the opposite side of the two baffles, and the inner wall of the filter barrel to form a cleaning chamber, which facilitates the cleaning of impurities.

[0040] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0041] See Figure 1-8 This application discloses a distillation water machine with heat recovery function and its usage method. For example... Figure 1 and Figure 2 As shown, a distillation water machine with heat recovery function includes a distillation water machine body 1, a filter 2 and a heat exchange box 3. The filter 2 includes a horizontally arranged filter barrel 21. A fixing seat 22 is installed on the inner wall of the filter barrel 21. The length direction of the fixing seat 22 is the same as the axial direction of the filter barrel 21. Filter plates 23 are provided on the upper and lower sides of the fixing seat 22. The filter plates 23 can slide and abut against the fixing seat 22 in the vertical direction. The filter barrel 21 is provided with two through grooves 211 for the corresponding filter plates 23 to slide through in the vertical direction.

[0042] When the two filter plates 23 slide close to each other until they both contact the fixed base 22, the fixed base 22 and the two filter plates 23 will jointly divide the interior of the filter barrel 21 into a semi-cylindrical filter chamber 212 and a clean chamber 213. The filter chamber 212 is connected to the distillation machine body 1 through an air pipe 24, and the clean chamber 213 is connected to the heat exchange box 3 through another air pipe 24. The steam generated by the distillation machine body 1 can enter the filter chamber 212 through the air pipe 24. The steam in the filter chamber 212 will be filtered by the filter plates 23 and then enter the clean chamber 213. The steam in the clean chamber 213 will be discharged into the heat exchange box 3 through the air pipe 24 for waste heat recovery.

[0043] like Figure 2 As shown, both the filter chamber 212 and the clean chamber 213 are equipped with baffles 25. One end of the baffle 25 is rotatably connected to the fixed base 22 via a horizontal shaft 251, and the other end of the baffle 25 rotates to abut against the inner wall of the filter barrel 21. This end of the baffle 25 can be flipped to the upper or lower side of the air pipe 24, so that the filter chamber 212 and the clean chamber 213 can be divided into two non-communicating chambers. That is, by rotating the baffle 25, the two filter plates 23 can alternately filter steam, and the workers do not need to stop the distillation of distilled water during the cleaning of the filter plates 23.

[0044] It is worth noting that when the end of the filter plate 23 facing the fixed seat 22 slides into the through groove 211, the impurities attached to the surface of the filter plate 23 will not be able to enter the through groove 211 with the filter plate 23. These impurities will be scraped off by the inner wall of the filter barrel 21, thus realizing the automatic cleaning of impurities on the surface of the filter plate 23.

[0045] like Figure 2 As shown, shovels 252 are installed on both the upper and lower sides of the baffle 25. The shovels 252 are attached to the inner wall of the filter barrel 21. When the two shovels 252 between the two baffles 25 are flipped and brought closer together, they will remove the impurities attached to the inner wall of the filter barrel 21. The two shovels 252 can be clamped together at one end of the filter plate 23 that slides into the through groove 211. At this time, the two shovels 252 will not be able to continue to flip and bring closer together. The blocking of the shovels 252 by the filter plate 23 realizes the positioning of the shovels 252 and the baffle 25.

[0046] When both baffles 25 are flipped to the upper or lower side of the air pipe 24 at the end away from the fixed seat 22, if the filter plate 23 slides into the through groove 211 at the end facing the fixed seat 22, the opposite side of the two baffles 25, the opposite side of the filter plate 23 and the fixed seat 22, and the inner wall of the filter barrel 21 will together form the impurity removal chamber 26. At this time, the impurities removed by the scraper 252 and the impurities scraped by the inner wall of the filter barrel 21 will be in the impurity removal chamber 26, while the other filter plate 23 can continue to filter the steam.

[0047] like Figure 3 and Figure 4As shown, each impurity removal chamber 26 is connected to an inlet pipe 261 and an outlet pipe 262. A one-way valve 263 is installed on the inlet pipe 261 and connected to a water pump 264. The one-way valve 263 only supplies water to the water pump 264 to enter the inlet pipe 261. A solenoid valve 265 is installed on the outlet pipe 262. The water pump 264 draws external water and introduces it into the impurity removal chamber 26 through the inlet pipe 261, flushing the inside of the impurity removal chamber 26. When the solenoid valve 265 is opened, the impurities in the impurity removal chamber 26 are discharged with the water through the outlet pipe 262, achieving rapid cleaning of impurities.

[0048] It is worth noting that the inlet pipe 261 is connected to the upper part of the impurity removal chamber 26 so that the water entering the impurity removal chamber 26 can flush the impurities in the upper part of the impurity removal chamber 26; the outlet pipe 262 is connected to the lower part of the impurity removal chamber 26 so that the sewage in the impurity removal chamber 26 can be discharged through the outlet pipe 262.

[0049] like Figure 2 and Figure 3 As shown, the clean chamber 213 is provided with top blocks 27 at both the upper and lower parts. The top blocks 27 slide through the filter barrel 21 along their own length direction. The top blocks 27 and the filter barrel 21 are connected to the same spring 271. The length direction of the spring 271 is the same as the length direction of the top blocks 27. The end of the top blocks 27 that extends into the filter barrel 21 is provided with a guide surface 272 for the shovel plate 252 to flip and abut against. The guide surface 272 is inclined.

[0050] like Figure 1 and Figure 2 As shown, it also includes a control unit 4, which includes a controller 41 and two contact sensors 42. The contact sensors 42 are mounted on the filter tank 21 and correspond one-to-one with the top block 27. The contact sensors 42, the water pump 264 and the solenoid valve 265 are all coupled to the controller 41.

[0051] When the filter plate 23 needs cleaning, the two baffles 25 will flip and approach the filter plate 23. The baffles 25 will drive the shovel 252 to flip synchronously. During the flipping process, the shovel 252 will push the top block 27 away from the inside of the filter barrel 21 through the guide surface 272. At this time, the shovel 252, the filter plate 23 and the filter barrel 21 have formed the impurity removal chamber 26. The top block 27 has come into contact with the contact sensor 42. The contact sensor 42 will send a flushing signal to the controller 41. The controller 41 will control the water pump 264 and the solenoid valve 265 to open for a specified time, realizing the automatic flushing of the impurity removal chamber 26.

[0052] like Figure 5 and Figure 6As shown, it also includes a lifting unit 5, which includes an incomplete gear 51 and two mating gears 52. The incomplete gear 51 is rotatably connected to the filter barrel 21. The mating gears 52 are rotatably connected to the filter barrel 21 via a rotating shaft 53. A turntable 54 is coaxially connected to the rotating shaft 53. The turntable 54 corresponds one-to-one with the filter plate 23 and is connected to a swing rod 55. One end of the swing rod 55 is rotatably connected to the turntable 54, and the other end of the swing rod 55 is rotatably connected to the filter plate 23.

[0053] During rotation, the incomplete gear 51 can mesh with any of the mating gears 52. The mating gear 52 will drive the turntable 54 to rotate via the rotating shaft 53. During rotation, the turntable 54 will drive the filter plate 23 to rise and fall via the rocker arm 55. That is, by rotating the incomplete gear 51, any filter plate 23 can be raised and lowered to clean impurities from the surface of the filter plate 23.

[0054] The incomplete gear 51 is coaxially connected to one of the horizontal shafts 251. Both horizontal shafts 251 are coaxially connected to drive gears 253. The two drive gears 253 mesh with each other. Therefore, by rotating one horizontal shaft 251, the horizontal shaft 251 will drive the other horizontal shaft 251 to rotate through the two drive gears 253, causing the two baffles 25 to flip and move closer to each other. At the same time, the horizontal shaft 251 will drive the incomplete gear 51 to rotate, and the incomplete gear 51 will drive one of the mating gears 52 to rotate. The mating gear 52 will drive the turntable 54 to rotate through the rotating shaft 53. The turntable 54 will drive the filter plate 23 located between the two baffles 25 to move away from the fixed seat 22 through the rocker arm 55. This realizes the automatic cleaning of impurities on the surface of the filter plate 23 and facilitates the two baffles 25 and the filter plate 23 to form the impurity removal chamber 26 together.

[0055] It is worth noting that a worm gear 254 is coaxially connected to one of the horizontal shafts 251, and a worm 255 meshes with the worm gear 254. The worm 255 rotates around its own axis and is connected to the filter barrel 21. When the worker rotates the worm 255, the worm 255 will drive the horizontal shaft 251 to rotate through the worm gear 254, so that the two filter plates 23 can alternately filter steam; and the self-locking function of the worm gear 254 and the worm 255 will keep the baffle 25 stable during use.

[0056] like Figure 7 and Figure 8 As shown, the filter plate 23 includes an outer frame 231 and an inner plate 232. The outer frame 231 is slidably embedded in the through groove 211 and is rotatably connected to the swing rod 55. The inner plate 232 is inserted into the outer frame 231 and has several filter holes. When the two shovel plates 252 are clamped together on the filter plate 23, the inner plate 232 will move to the outside of the filter barrel 21. At this time, the worker can disassemble the inner plate 232 for deep cleaning or replacement.

[0057] The inner wall of the outer frame 231 is provided with a receiving groove 233, and an elastic column 234 is installed in the receiving groove 233. One end of the elastic column 234 is hemispherical and protrudes out of the receiving groove 233. The side wall of the inner plate 232 is provided with a slot 235 for the hemispherical end of the elastic column 234 to be inserted. During the process of the inner plate 232 being inserted into the outer frame 231, the side wall of the inner plate 232 will squeeze the elastic column 234, causing the elastic column 234 to deform and sink into the receiving groove 233. After the inner plate 232 is inserted into the outer frame 231, the hemispherical end of the elastic column 234 will be inserted into the slot 235, so that the inner plate 232 is locked and fixed in the outer frame 231, ensuring the stability of the filter plate 23 during use.

[0058] The working principle of this application is as follows: During the distillation process, the water distillation machine body 1 will distill the water. The steam generated by distillation will enter the filter chamber 212 through the gas pipe 24. The steam in the filter chamber 212 will enter the clean chamber 213 after being filtered by one of the filter plates 23. The steam in the clean chamber 213 will enter the heat exchange box 3 through the gas pipe 24 for preheating and recovery.

[0059] When filter plate 23 becomes clogged and needs cleaning, the worker rotates the worm gear 255. The worm gear 255 drives one of the horizontal shafts 251 to rotate via the worm wheel 254. This horizontal shaft 251 then drives another horizontal shaft 251 to rotate via two drive gears 253. This causes the two baffles 25 to flip and approach the filter plate 23 to be cleaned. During the flipping process, the baffles 25 drive the scraper 252 to remove impurities adhering to the inner wall of the filter barrel 21. At the same time, the horizontal shaft 251 drives the incomplete gear 51 to rotate. The incomplete gear 51 drives one of the mating gears 52 to rotate. The mating gear 52 drives the turntable 54 to rotate via the rotating shaft 53. The turntable 54 then drives the filter plate 23 to be cleaned to move away from the fixed seat 22 via the swing rod 55. The inner wall of the filter barrel 21 will scrape off the impurities adhering to the surface of the filter plate 23. Then, the two baffles 25 are positioned opposite each other, and the filter plate 23 to be cleaned is positioned opposite the fixed seat 22. The impurities removed by the scraper plate 252 and the inner wall of the filter barrel 21 together form the impurity removal chamber 26. The impurities removed by the scraper plate 252 and the impurities scraped by the inner wall of the filter barrel 21 will be in the impurity removal chamber 26. During the flipping process, the scraper plate 252 will push the top block 27 away from the inner side of the filter barrel 21 through the guide surface 272 and abut against the contact sensor 42. The contact sensor 42 will send a flushing signal to the controller 41. The controller 41 will control the water pump 264 and the solenoid valve 265 to open for a specified time. The water pump 264 will draw water from the external water source and enter the impurity removal chamber 26 through the water inlet pipe 261. The water will flush the inside of the impurity removal chamber 26. The impurities in the impurity removal chamber 26 will be discharged with the water through the water outlet pipe 262, realizing the rapid cleaning of impurities. In addition, the worker can also remove the inner plate 232 on the filter plate 23 to be cleaned for deep cleaning or replacement, while the other filter plate 23 can continue to filter steam.

[0060] In summary, this application achieves uninterrupted filtration of steam and rapid removal of impurities by alternating the use of two filter plates 23, thereby improving the distillation efficiency of distilled water.

[0061] This application also discloses a method for using a distilled water machine with heat recovery function. A method for using a distilled water machine with heat recovery function includes the following steps;

[0062] S1. During the filtration process of steam generated by distilled water, the ends of the two baffles 25 away from the fixed base 22 will be located on the upper or lower side of the air pipe 24 at the same time. The steam generated by the distillation water machine body 1 will enter the filter chamber 212 through one of the air pipes 24. After being filtered by one of the filter plates 23, the steam will enter the clean chamber 213 and enter the heat exchange box 3 through the other air pipe 24 for waste heat recovery. The two filter plates 23 are used alternately to achieve uninterrupted filtration of steam.

[0063] S2. When the filter plate 23 is clogged and needs cleaning, the worker will rotate the worm 255. The worm 255 will drive one of the horizontal shafts 251 to rotate via the worm wheel 254. This horizontal shaft 251 will drive another horizontal shaft 251 to rotate via two drive gears 253, causing the two baffles 25 to flip and approach the filter plate 23 to be cleaned. During the flipping process, the baffles 25 will drive the scraper 252 to remove the impurities attached to the inner wall of the filter barrel 21. At the same time, the horizontal shaft 251 will drive the incomplete gear 51 to rotate, which will drive one of the mating gears 52 to rotate. The mating gear 52 will drive the turntable 54 to rotate via the rotating shaft 53. The turntable 54 will drive the filter plate 23 to be cleaned to move away from the fixed seat 22 via the swing rod 55. The impurities attached to the surface of the filter plate 23 will be scraped off the inner wall of the filter barrel 21. Then, the filter plate 23 to be cleaned will move away from the fixed seat 22 on the opposite side of the two baffles 25. The side of plate 23 opposite to the fixed base 22 and the inner wall of filter barrel 21 together form a cleaning chamber 26. Impurities removed by scraper plate 252 and impurities scraped by the inner wall of filter barrel 21 will be in the cleaning chamber 26. During the flipping process, scraper plate 252 will push top block 27 away from the inside of filter barrel 21 through guide surface 272 and abut against contact sensor 42. Contact sensor 42 will send a flushing signal to controller 41. Controller 41 will control water pump 264 and solenoid valve 265 to open for a specified time.
