Description

Technical Field

[0001] The invention belongs to the field of water treatment, in particular to a distilled water treatment device. Background Art

[0002] Animal husbandry veterinary drugs mainly include antimicrobial drugs, antiparasitic drugs, vaccines and reproductive hormones. Among reproductive hormone veterinary drugs, sterile injection is one of the important dosage forms. This type of preparation requires ultrapure distilled water (such as water for injection that meets pharmacopoeia standards) as a solvent or diluent during the production process. In order to ensure product quality, it is necessary to conduct systematic chemical research to evaluate the effects of different quality grades of distilled water on drug stability.

[0003] It is worth noting that the core component of the distilled water treatment device used to prepare ultra-pure distilled water, the evaporator, will face the problem of scale deposition during long-term operation. The evaporator generates water vapor by heating raw water, and minerals such as calcium and magnesium ions in the water will gradually deposit on the inner wall to form scale during the heating process. These scales not only reduce the heat conduction efficiency and affect the heating performance of the evaporator, but more importantly, may cause fluctuations in the quality of the distilled water, thereby affecting the stability of the final drug preparation.

[0004] Therefore, while conducting research on the impact of distilled water quality on drug stability, the scale on the distillation equipment needs to be treated to ensure the stability and consistency of the distilled water production process. Existing devices mostly use cleaning mechanisms to regularly clean the inner wall of the evaporator to remove scale and impurities on the inner wall of the evaporator to ensure the heating performance of the evaporator and the stability and consistency of the distilled water production process. However, the evaporator needs to be shut down for cleaning, and frequent shutdowns for cleaning operations affect research efficiency.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 9 As shown, a distilled water treatment device according to an embodiment of the present invention includes a preheater 1, multiple groups of evaporators 2 and condensers 3, wherein the multiple groups of evaporators 2 are connected to the respective condensers 3, and further includes: a pressure reducer 4, which is used to remove air in raw water, and is located between the preheater 1 and the multiple groups of evaporators 2, and is connected to the preheater 1 and the multiple groups of evaporators 2, respectively; a bubble generating part 5, which includes a No. 1 tube 51 installed in the evaporator 2, and a plurality of pores 52 are provided on the No. 1 tube 51. When the evaporator 2 is filled with raw water, the No. 1 tube 51 is immersed in the raw water, and air is introduced into the No. 1 tube 51, and the air is discharged from the pores 52 to form steam bubbles. After the steam bubbles escape, the local moisture is reduced, the concentration of the remaining minerals is increased, and scale is deposited on the outside of the No. 1 tube 51.

[0023] Specifically, the existing devices mostly use a cleaning mechanism to regularly clean the inner wall of the evaporator 2 to remove scale and impurities on the inner wall of the evaporator 2 to ensure the heating performance of the evaporator 2 and the stability and consistency of the distilled water production process. However, the evaporator 2 needs to be shut down for cleaning, and frequent shutdown and cleaning operations affect the research efficiency. The pressure reducer 4 is connected to the air extraction device. A stirring paddle can be arranged inside the pressure reducer 4 to stir the raw water synchronously during the air extraction process to accelerate the discharge of air in the raw water. Before working, the No. 1 pipe 51 is connected to the blower. During working, the raw water is first preheated by the preheater 1 and then enters the pressure reducer 4. The pressure reducer 4 discharges the air in the raw water. The raw water with the air discharged enters the evaporator 2 for heating and evaporation. The steam generated by evaporation enters the condenser 3 for condensation. The condensed water is distilled water, and the distilled water treatment action is completed. In the process of heating the raw water by the evaporator 2 of the existing device, the temperature of the water rises, the solubility of air in the water decreases, and the air in the raw water escapes from the water to form bubbles and adhere to the inner wall. With the subsequent continuous heating, the water absorbs enough heat to change from liquid to gas, forming water vapor bubbles. When the bubbles burst and escape upward, the calcium salts and magnesium salts in the surrounding water are oversaturated, so that they are precipitated and retained on the inner wall of the evaporator 2. During the process of heating and evaporating the raw water in the evaporator 2, hot air is continuously introduced into the evaporator 2 through the No. 1 pipe 51. The hot air contacts the raw water through the pores 52 to form water vapor bubbles. These bubbles continue to rise and burst. After the steam bubbles escape, the local moisture decreases and the remaining mineral concentration increases, which will cause scale to be deposited on the outside of the No. 1 pipe 51. At the same time, the setting of the pressure reducer 4 effectively reduces the air content in the raw water and reduces the generation of bubbles on the inner wall of the evaporator 2. Therefore, the deposition position of the scale can be transferred from the inner wall of the evaporator 2 to the outside of the No. 1 pipe 51, thereby improving the problem of scale deposition on the inner wall of the evaporator 2 affecting the heating efficiency of the evaporator 2. The deposition of scale on the inner wall of the evaporator 2 is reduced, the cleaning frequency is reduced, and the research efficiency is improved.

[0024] like Figure 2 and Figure 6 As shown, the evaporator 2 is provided with a raw water inlet 21, a steam outlet 22 and a wastewater discharge port 23. The evaporator 2 is connected to the pressure reducer 4 through the raw water inlet 21, and the evaporator 2 is connected to the condenser 3 through the steam outlet 22. The bubble generating part 5 also includes a baffle 53 and a disturbance component 54 fixedly installed inside the evaporator 2. The baffle 53 surrounds the outer periphery of the No. 1 pipe 51, and when the evaporator 2 is filled with raw water, the baffle 53 is immersed in the raw water. The disturbance component 54 is used to control the exchange of water flow inside and outside the baffle 53.

[0025] Specifically, the inner wall of the enclosure 53 adopts a rough surface design, and the outer surface of the No. 1 pipe 51 adopts a smooth surface design. Such a design helps to provide more attachment points for scale. Since the No. 1 pipe 51 is provided with air holes 52, there is a risk of scale deposition clogging the air holes 52. By arranging the enclosure 53 outside the No. 1 pipe 51, the gas flows through the air holes 52 to form bubbles and adheres to the outside of the enclosure 53 to form an air film. These air films will capture mineral particles in the water. When the bubbles burst on the rough surface, they will release energy and "push" the mineral particles in the water to the surface, accelerating the deposition of scale, thereby achieving the purpose of depositing scale on the surface of the enclosure 53 and protecting the No. 1 pipe 51. The disturbance component 54 controls the water flow to exchange inside and outside the enclosure 53 to ensure that as many minerals in the water as possible adhere to the inner wall of the enclosure 53.

[0026] like Figure 7 and Figure 8 As shown, the disturbance assembly 54 includes: a circular plate 541, which is mounted on the bottom of the evaporator 2; a through hole 542, which has a plurality of holes and is opened on the circular plate 541, and the through hole 542 communicates the inside and the outside of the enclosure 53; a slide plate 543, which is slidably mounted inside the through hole 542; a first screw rod 544, which is threadedly connected to the slide plate 543 and is rotatably mounted on the circular plate 541; and a first plate 545. And No. 2 plate 546, No. 1 plate 545 is slidably installed on the through hole 542, a telescopic rod 547 is installed between No. 1 plate 545 and the circular plate 541, No. 2 plate 546 is slidably installed on the slide plate 543, the slide plate 543 slides upward, No. 1 plate 545 slides into the through hole 542, the water outside the enclosure 53 enters the through hole 542, the slide plate 543 slides downward, No. 1 plate 545 is closed, No. 2 plate 546 is opened, and the water in the through hole 542 enters the interior of the enclosure 53.

[0027] Specifically, the No. 1 screw rod 544 adopts a reciprocating screw rod. When the evaporator 2 is working, the No. 1 screw rod 544 is controlled to rotate, driving the slide plate 543 to move back and forth up and down in the through hole 542. When the slide plate 543 moves upward, the pressure in the through hole 542 decreases, so the No. 1 plate 545 slides inward, allowing the water flow outside the enclosure 53 to enter the through hole 542. When the slide plate 543 slides downward, the No. 1 plate 545 returns to its original position under the action of the elastic force of the telescopic rod 547. Therefore, the No. 2 plate 546 slides upward relative to the slide plate 543, allowing the internal water flow to flow out of the through hole 542 and enter the interior of the enclosure 53. Since the height of the enclosure 53 is less than the liquid height in the evaporator 2, the water flow inside and outside the enclosure 53 can be circulated and exchanged.

[0028] like Figure 5 and Figure 7As shown, the No. 1 tube 51 is rotationally connected to the evaporator 2, the circular plate 541 is fixedly connected to the No. 1 tube 51, the disturbance assembly 54 also includes a No. 1 gear 548 fixedly installed at the lower end of the No. 1 screw rod 544, and the No. 2 gear 6 is fixedly installed on the evaporator 2, and the No. 1 gear 548 is meshingly connected with the No. 2 gear 6.

[0029] Specifically, during operation, the No. 1 pipe 51 is controlled to rotate so that the bubbles can be sprayed evenly on the enclosure 53. The rotation of the No. 1 pipe 51 drives the circular plate 541 to rotate synchronously. The rotation of the circular plate 541 drives the No. 1 gear 548 to rotate. Since the No. 2 gear 6 remains stationary, the No. 1 gear 548 rotates. The rotation of the No. 1 gear 548 drives the No. 1 screw rod 544 to rotate, so that the water inside and outside the enclosure 53 is circulated and exchanged.

[0030] like Figure 2-Figure 6 As shown, the device also includes a cleaning part 7, which includes: a No. 1 ring 71, which is rotatably mounted in the evaporator 2; a No. 2 tube 72, which is slidably connected to the No. 1 ring 71; a No. 2 screw rod 73, which is rotatably mounted in the evaporator 2 and is threadedly connected to the No. 2 tube 72; a No. 1 plug plate 74 and a No. 2 plug plate 75, which are both slidably mounted on the No. 2 tube 72; a No. 1 wiper plate 76 and a No. 2 wiper plate 77. No. 1 wiper plate 77, No. 1 wiper plate 76 and No. 2 wiper plate 77 are all slidably mounted on No. 1 plug plate 74 and No. 2 plug plate 75; No. 1 ring 78 and No. 2 ring 79, No. 1 ring 78 and No. 2 ring 79 are rotatably mounted on No. 1 pipe 51 and enclosure 53 respectively; No. 1 connecting rod 710 and No. 2 connecting rod 711, the two ends of No. 1 connecting rod 710 are rotatably connected with No. 1 ring 78 and No. 1 plug plate 74 respectively, and the two ends of No. 2 connecting rod 711 are rotatably connected with No. 2 ring 79 and No. 2 plug plate 75 respectively.

[0031] Specifically, when a lot of scale is deposited on the inner wall of the evaporator 2, the valves on the pipelines between the evaporator 2, the pressure reducer 4 and the condenser 3 are first controlled to be closed, and then the No. 2 screw rod 73 and the No. 1 ring 71 are controlled to remain stationary, and the No. 1 tube 51 continues to rotate. At this time, the No. 2 wiper 77 fits the wall surface of the No. 1 tube 51, so the No. 2 wiper 77 can wipe the outer wall of the No. 1 tube 51, and then the No. 1 ring 71 is controlled to remain stationary, and the No. 2 screw rod 73 rotates, driving the No. 2 tube 72 to slide downward, and the No. 2 tube 72 slides downward, so that the No. 1 plug plate 74 and the No. 2 plug plate 75 slide downward relative to the No. 1 wiper plate 76 and the No. 2 wiper plate 77, so that the No. 1 connecting rod 710 and the No. 2 connecting rod 711 rotate, and the No. 1 ring 71 is controlled to remain stationary. The connecting rod 710 and the second connecting rod 711 rotate to push the first wiper plate 76 and the second wiper plate 77 to slide until the first wiper plate 76 fits against the inner wall of the body and the second wiper plate 77 fits against the inner wall of the enclosure 53. Then the first ring 71 is controlled to rotate together with the second screw rod 73, so that the second tube 72 rotates synchronously. The rotation of the second tube 72 drives the first wiper plate 76 and the second wiper plate 77 to rotate, so as to clean the scale on the inner wall of the evaporator 2 and the inner wall of the enclosure 53. The cleaned sewage is discharged from the wastewater discharge port 23. By setting the cleaning part 7, the enclosure 53 and the evaporator 2 are cleaned to ensure the heating efficiency of the evaporator 2 and the deposition effect of the enclosure 53 on the scale. No disassembly operation is required, and it is easy to use.

[0032] like Figure 3 and 9 As shown, the cleaning portion 7 also includes: a liquid outlet 712, which is opened at the upper end of the No. 2 tube 72; a baffle 713, which is slidably installed on the No. 2 tube 72, and the baffle 713 is used to block the liquid outlet 712. The baffle 713 is located within the moving range of the No. 1 plug plate 74, and the contact surface between the baffle 713 and the No. 1 plug plate 74 is an inclined surface.

[0033] Specifically, when distilling raw water, the No. 2 pipe 72 is connected to the blower to achieve the purpose of producing bubbles in the raw water. When the evaporator 2 and the enclosure 53 need to be cleaned, a detergent capable of softening scale is introduced into the No. 2 pipe 72. The detergent is discharged from the air hole 52 and flows to the outer wall of the No. 1 pipe 51. With the No. 2 wiping plate 77, it can be cleaned more thoroughly. Then, when the No. 1 wiping plate 76 is attached to the inner wall of the evaporator 2 and the No. 2 wiping plate 77 is in contact with the inner wall of the enclosure 53, the baffle 713 is not blocked by the No. 1 wiping plate 76 and moves downward under the action of gravity, so that the interior of the No. 2 pipe 72 is in contact with the evaporator 2 through the liquid outlet 712. The interior of the evaporator 2 is connected, and the detergent can flow to the inner wall of the evaporator 2 through the liquid outlet 712. In conjunction with the No. 1 wiping plate 76, it can be cleaned more thoroughly. After cleaning, the No. 1 wiping plate 76 moves toward the direction close to the enclosure 53 under the drive of the No. 1 plug plate 74. During the movement, the No. 1 plug plate 74 contacts the baffle 713 and pushes the baffle 713 to move upward until the baffle 713 blocks the liquid outlet 712 to ensure that the gas cannot be discharged from the liquid outlet 712 during operation; by setting the liquid outlet 712, the detergent is sprayed onto the inner wall of the evaporator 2, and in conjunction with the No. 2 wiping plate 77, the cleaning effect can be better.

[0035] like Figure 4 As shown, the cleaning part 7 further includes a first electromagnetic block 721 and a second electromagnetic block 722 , and the first electromagnetic block 721 and the second electromagnetic block 722 are respectively mounted on the protrusion of the second tube 72 and in the groove 715 .

[0036] like Figure 2-Figure 6As shown, the cleaning portion 7 also includes a third gear 724 and a fourth gear 725 rotatably mounted in the evaporator 2, a ratchet 726 is fixedly mounted on the abutment plate 719, the third gear 724 is meshedly connected with the drive plate 716 and the fourth gear 725, the fourth gear 725 is used to intermittently drive the ratchet 726 to rotate, and a ratchet pawl 727 is rotatably mounted in the evaporator 2, the ratchet pawl 727 is used to limit the one-way rotation of the ratchet 726.

[0037] Specifically, the teeth of the fourth gear 725 are incomplete teeth. In the initial state, the first electromagnetic block 721 and the second electromagnetic block 722 are in a state of being energized and in contact with each other, and the spring 720 is in a stretched state. During operation: the driving plate 716 rotates to drive the No. 2 circular ring 714 and the push rod 717 to rotate clockwise, the push rod 717 drives the No. 2 screw rod 73 to rotate through the No. 1 triangular block 718, the No. 2 circular ring 714 drives the No. 1 circular ring 71 to rotate synchronously through the No. 1 electromagnetic block 721 and the No. 2 electromagnetic block 722, the No. 1 circular ring 71 rotates to drive the No. 2 tube 72 to rotate synchronously, because the No. 2 tube 72 and the No. 2 screw rod 73 rotate synchronously, the No. 2 tube 72 does not extend or retract, and the No. 2 tube 72 rotates to drive the No. 1 wiper plate 76 and the No. 2 wiper plate 77 to rotate synchronously, which can stir the raw water of the evaporator 2, not only making the raw water evenly heated, but also fully ensuring that the raw water can pass between the enclosure 53 and the No. 1 tube 51, so that more scale can be deposited on the inner wall of the enclosure 53, in this process, the abutment plate 719 extends and retracts to facilitate the passage of the No. 2 triangular block 723 and the driving plate 716; When the device needs to be cleaned: the first electromagnetic block 721 and the second electromagnetic block 722 are powered off, and then the first ring 71 drives the second tube 72 to rotate clockwise relative to the second screw rod 73 under the elastic force of the spring 720, so that the second tube 72 moves downward relative to the first ring 71, so that the first wiper plate 76 fits against the inner wall of the evaporator 2, and the second wiper plate 77 fits against the inner wall of the enclosure 53, and then the first ring 71, the second screw rod 73 and the first ring 71 rotate at the same speed. During the rotation, the first wiper plate 76 and the second wiper plate 77 clean the inner walls of the evaporator 2 and the enclosure 53. When the second triangle block 723 When rotating to contact with the plate 719, the second screw rod 73 and the second ring 714 continue to rotate with the driving plate 716, and the first ring 71 is blocked by the plate 719 and remains motionless, so the second tube 72 slides upward relative to the first ring 71, so that the second wiper plate 77 fits the inner wall of the first tube 51, and then the second screw rod 73 is affected by the second tube 72 and remains motionless. At this time, the push rod 717 is extended and retracted through the first triangular block 718. Since the second wiper plate 77 remains motionless, the second ring 714 and the first tube 51 continue to rotate, so the second wiper plate 77 can wipe the outer wall of the first tube 51, and the spring 720 is stretched at this time; When the protrusion of the No. 1 ring 71 contacts the end of the sliding groove of the No. 2 ring 714, that is, the No. 1 magnetic block contacts the No. 2 magnetic block, the No. 1 ring 71 and the No. 2 screw rod 73 can rotate under the push of the No. 2 ring 714, at this time, the plate 719 is extended to allow the No. 1 ring 71 to pass, and then the No. 1 wiper plate 76 is repeated to fit the inner wall and shrink, so as to clean the inner wall of the evaporator 2; During the cleaning process, the No. 1 ring 71 rotates through the No. 3 gear 724 to drive the No. 4 gear 725, and the No. 4 gear 725 intermittently drives the ratchet 726 and the abutment plate 719 to rotate, so that when the triangular block on the No. 1 ring 71 rotates one circle, the position of contact with the abutment plate 719 is different, so that the No. 1 wiping plate 76 and the No. 2 wiping plate 77 contact the inner wall of the evaporator 2, the surrounding plate 53 and the No. 1 tube 51 at different positions, so that after multiple rotations, the No. 1 wiping plate 76 and the No. 2 wiping plate 77 can clean all positions of the inner wall of the evaporator 2, the surrounding plate 53 and the No. 1 tube 51.

[0038] Working principle: Before operation, the No. 1 pipe 51 is connected to the blower. During operation, the raw water is first preheated by the preheater 1, and then enters the pressure reducer 4. The pressure reducer 4 discharges the air in the raw water, and the raw water with the air discharged enters the evaporator 2 for heating and evaporation. During the heating and evaporation of the raw water in the evaporator 2, hot air is continuously introduced into the evaporator 2 through the No. 1 pipe 51. The hot air contacts the raw water through the air holes 52 to form water vapor bubbles. The bubbles are attached to the outside of the enclosure 53 to form an air film. These air films will capture mineral particles in the water. When the bubbles burst on the rough surface, when the bubbles burst on the surface of the enclosure 53 and escape upward, the calcium salts and magnesium salts in the surrounding water will be oversaturated, and thus precipitate out in the form of precipitation, and release energy to "push" the mineral particles in the water to the surface of the enclosure 53, accelerating the deposition of scale, thereby transferring the deposition position of the scale from the inner wall of the evaporator 2 to the enclosure 53. At the same time, the driving plate 716 is controlled to rotate to drive the No. 2 ring 714 and the push rod 717 to rotate clockwise, and the push rod 717 drives the No. 2 screw rod 73 to rotate through the No. 1 triangular block 718, and the No. 2 ring 714 drives the No. 1 ring 71 to rotate synchronously through the No. 1 electromagnetic block 721 and the No. 2 electromagnetic block 722, and the No. 1 ring 71 rotates to drive the No. 2 tube 72 to rotate synchronously. Since the No. 2 tube 72 and the No. 2 screw rod 73 rotate synchronously, the No. 2 tube 72 does not extend or retract, and the rotation of the No. 2 tube 72 drives the No. 1 wiper plate 76 and the No. 2 wiper plate 77 to rotate synchronously, so as to stir the raw water of the evaporator 2, which can not only make the raw water evenly heated, but also fully ensure that the raw water can pass between the enclosure 53 and the No. 1 tube 51, so that more scale can be deposited on the inner wall of the enclosure 53; The rotation of the No. 2 ring 714 drives the No. 1 tube 51 to rotate, and the No. 1 tube 51 rotates so that the bubbles can be evenly sprayed on the enclosure 53. The rotation of the No. 1 tube 51 drives the circular plate 541 to rotate synchronously. The rotation of the circular plate 541 drives the No. 1 gear 548 to rotate. Since the No. 2 gear 6 remains stationary, the No. 1 gear 548 rotates. The rotation of the No. 1 gear 548 drives the No. 1 screw rod 544 to rotate. The rotation of the No. 1 screw rod 544 drives the slide plate 543 to move up and down in the through hole 542. When the slide plate 543 moves upward, the pressure in the through hole 542 decreases. Therefore, the first plate 545 slides inwardly, so that the water flow outside the enclosure 53 enters the through hole 542. When the slide plate 543 slides downwardly, the first plate 545 returns to its original position under the elastic force of the telescopic rod 547. Therefore, the second plate 546 slides upwardly relative to the slide plate 543, so that the internal water flows out of the through hole 542 and enters the interior of the enclosure 53. Since the height of the enclosure 53 is less than the height of the liquid in the evaporator 2, the water flow inside and outside the enclosure 53 can be circulated and exchanged to further ensure that the minerals in the water are attached to the inner wall of the enclosure 53 as much as possible. The steam generated by evaporation enters the condenser 3 for condensation, and the condensed steam is distilled water, which completes the distilled water treatment process; When the device needs to be cleaned, a detergent capable of softening scale is introduced into the No. 2 pipe 72, and the detergent is discharged from the air hole 52 and the liquid outlet 712, and flows to the outer wall of the No. 1 pipe 51, the inner wall of the enclosure 53 and the inner wall of the evaporator 2, and the No. 1 electromagnetic block 721 and the No. 2 electromagnetic block 722 are controlled to be powered off, and then the No. 1 ring 71 drives the No. 2 pipe 72 to rotate clockwise relative to the No. 2 screw rod 73 under the action of the elastic force of the spring 720, so that the No. 2 pipe 72 moves downward relative to the No. 1 ring 71, so that the No. 1 wiper plate 76 fits against the inner wall of the evaporator 2, and the No. 2 wiper plate 77 fits against the inner wall of the enclosure 53, and then the No. 1 ring 71, the No. 2 screw rod 73 and the No. 1 ring 71 rotate at the same speed, and the No. 1 wiper plate 76 and the No. 2 wiper plate 77 clean the inner wall of the evaporator 2 and the enclosure 53 during the rotation; When the second triangular block 723 rotates to contact the abutment plate 719, the second screw rod 73 and the second ring 714 continue to rotate with the driving plate 716, and the first ring 71 is blocked by the abutment plate 719 and remains motionless, so the second tube 72 slides upward relative to the first ring 71, so that the second wiper plate 77 fits the inner wall of the first tube 51, and then the second screw rod 73 is affected by the second tube 72 and remains motionless. At this time, the push rod 717 is extended and retracted through the first triangular block 718. Since the second wiper plate 77 remains motionless, the second ring 714 and the first The tube 51 continues to rotate, so the second wiper plate 77 can wipe the outer wall of the first tube 51. At this time, the spring 720 is stretched. When the protrusion of the first ring 71 contacts the end of the sliding groove of the second ring 714, that is, the first magnetic block contacts the second magnetic block, the first ring 71 and the second screw rod 73 can rotate under the push of the second ring 714. At this time, the plate 719 is extended to allow the first ring 71 to pass through, and then the first wiper plate 76 is repeated to fit the inner wall and shrink, so as to clean the inner wall of the evaporator 2. During the cleaning process, the No. 1 ring 71 rotates through the No. 3 gear 724 to drive the No. 4 gear 725, and the No. 4 gear 725 intermittently drives the ratchet 726 and the abutment plate 719 to rotate, so that when the triangular block on the No. 1 ring 71 rotates one circle, the position of contact with the abutment plate 719 is different, so that the No. 1 wiping plate 76 and the No. 2 wiping plate 77 contact the inner wall of the evaporator 2, the surrounding plate 53 and the No. 1 tube 51 at different positions, so that after multiple rotations, the No. 1 wiping plate 76 and the No. 2 wiping plate 77 can clean all positions of the inner wall of the evaporator 2, the surrounding plate 53 and the No. 1 tube 51.
