Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine concentration equipment, specifically, it relates to a wind pressure defoaming type high-efficiency concentration machine. Background Technology

[0002] Currently, the concentration of traditional Chinese medicine (TCM) liquids mainly uses ordinary concentrators or jacketed kettles, which have drawbacks such as limited functionality, low concentration efficiency, and significant environmental pollution. The concentration efficiency of TCM liquids is primarily limited by the large amount of foam generated during concentration, which hinders evaporation. Residual medicinal liquid in the foam overflows, causing waste and environmental pollution. Commonly used evaporators have small heat dissipation areas, which are not conducive to rapid evaporation. Furthermore, some heat-sensitive medicinal liquids require low-temperature concentration, necessitating equipment capable of both atmospheric and negative pressure modes.

[0003] Currently, with the diversification of traditional Chinese medicine (TCM) products, the number of ointments and powders has increased, leading to higher demands and efficiency requirements for TCM liquid concentration. The current concentration efficiency no longer meets market needs, severely impacting the production schedule of subsequent ointments and powders and hindering the development of TCM products.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wind pressure defoaming type high-efficiency concentrator. In the present invention, the water vapor generated by the medicine liquid heating tank can exchange heat with the air introduced into the medicine liquid heating tank in the air supply pipeline of the wind pressure defoaming structure, so that the water vapor can be condensed at the same time as the wind pressure defoaming, without the need to add an additional cooling device to achieve the purpose of water vapor condensation, thus simplifying the structure of the medicine liquid concentrator.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A high-efficiency concentrator with air pressure defoaming is provided, comprising: a medicine heating tank for heating a medicine liquid stored in the tank; an air pressure defoaming structure for introducing air into the medicine heating tank for defoaming treatment, including an air supply pipe connected to the medicine heating tank; and a combined condensation structure, including an inner tube of an air-cooled component connected to the medicine heating tank, wherein water vapor generated by heating in the medicine heating tank enters the inner tube of the air-cooled component and exchanges heat with the air flowing in the air supply pipe in the inner tube of the air-cooled component to achieve condensation of water vapor.

[0008] Furthermore, the air supply duct includes an outer tube of the air-cooled component, and an inner tube of the air-cooled component is nested inside the outer tube of the air-cooled component.

[0009] Furthermore, the air inlet end of the inner tube of the air-cooled component is connected to the defoaming cylinder through the main exhaust pipe, the defoaming cylinder and the medicine heating tank are connected through the auxiliary exhaust pipe, and the air outlet end of the inner tube of the air-cooled component is connected to the water-cooled component.

[0010] Furthermore, the wind pressure defoaming structure includes a fan, the air inlet end of the outer pipe of the air-cooled component is connected to the fan through the main air pipe, and the air outlet end of the outer pipe of the air-cooled component is connected to the liquid heating tank through the auxiliary air pipe.

[0011] Furthermore, at least two medicine liquid heating tanks are provided, and multiple air outlets are provided on the outer pipe side wall of the air-cooling component, which are connected to each medicine liquid heating tank one by one through multiple auxiliary air pipes.

[0012] Furthermore, the combined condensation structure also includes a water-cooling component located below the liquid heating tank, comprising a cold water tank, a steam condenser pipe located inside the cold water tank and connected to the outlet end of the inner tube of the air-cooling component, a vacuum box for retaining condensate, and a vacuum pump connected to the vacuum box for providing negative pressure.

[0013] Furthermore, it also includes a liquid circulation unit, which includes a liquid outlet connected to a liquid heating tank, a hot water circulation pump for driving liquid circulation, a main circulation pipe connected to the liquid inlet of the hot water circulation pump, a secondary circulation pipe connected to the bottom of the liquid heating tank, and a defoaming cylinder connected to the liquid heating tank through a secondary exhaust pipe. The secondary circulation pipe and the foam liquid pipe connected to the liquid outlet of the defoaming cylinder are respectively connected to the main circulation pipe.

[0014] Furthermore, the medicine circulation unit also includes a return pipe connected to the outlet end of the hot water circulation pump, and the outlet end of the return pipe is connected to the upper part of the medicine heating tank.

[0015] Furthermore, it also includes an automatic cleaning unit, which includes a cleaning inlet pipe for connecting to an external water source. The outlet end of the cleaning inlet pipe is connected to the upper part of the defoaming cylinder, and the lower part of the defoaming cylinder is provided with a liquid outlet end, which is connected to a downwardly extending foam liquid pipe.

[0016] Furthermore, during the cleaning process, the cleaning water sequentially passes through the cleaning inlet pipe, defoaming cylinder, and foam liquid pipe into the main circulation pipe. Then, driven by the hot water circulation pump, it enters the chemical heating tank along the return pipe and then re-enters the main circulation pipe through the auxiliary circulation pipe connected to the bottom of the tank for circulating cleaning.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. By blowing air into the heating tank of the medicine liquid, the air flow rate on the surface of the concentrated medicine liquid in the tank is accelerated, the discharge of hot steam is accelerated, and the bubbles on the surface of the medicine liquid are impacted and destroyed, which helps to defoam and improve the evaporation efficiency.

[0019] 2. The air generated by the fan is introduced into the liquid heating tank through the outer pipe of the air-cooled component, while hot steam is blown out. After the hot steam enters the inner pipe of the air-cooled component, it exchanges heat with the flowing air passing through the outer pipe, which makes the steam condense faster and also heats the air entering the tank, reducing the impact of cold air entering the air heating tank on the temperature inside the tank.

[0020] 3. The water vapor generated by the medicine liquid heating tank can exchange heat with the air supplied to the medicine liquid heating tank in the air supply duct of the wind pressure defoaming structure, so that the water vapor can be condensed at the same time as the wind pressure defoaming, without the need to add an additional cooling device to achieve water vapor condensation, thus simplifying the structure of the medicine liquid concentrator.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a wind pressure defoaming type high-efficiency concentrator, including a liquid heating tank, a wind pressure defoaming structure, and a combined condensation structure.

[0035] The medicine liquid heating tank 1 is used to heat the medicine liquid stored in the tank. The air pressure defoaming structure is used to introduce air into the medicine liquid heating tank 1 for defoaming treatment, and includes an air supply pipe connected to the medicine liquid heating tank. The combined condensation structure includes an inner pipe 201 of the air-cooled component connected to the medicine liquid heating tank. Water vapor generated by the medicine liquid heating tank enters the inner pipe 201 of the air-cooled component and exchanges heat with the air introduced into the air supply pipe to cool down, thereby realizing the condensation of water vapor.

[0036] Specifically, a heating ring is provided at the bottom of the medicine liquid heating tank 1. The heating ring is fixed to the bottom of the tank and can effectively heat and concentrate the medicine liquid stored in the medicine liquid heating tank.

[0037] In order to achieve heat exchange between the water vapor generated by the medicine liquid heating tank 1 and the air introduced into the air supply pipeline, the air supply pipeline includes an outer tube 202 of the air-cooled component, and an inner tube 201 of the air-cooled component is nested inside the outer tube 202 of the air-cooled component.

[0038] The air-cooling component consists of an outer tube 202 and an inner tube 201. The outer tube 202 is used to introduce air into the medicine heating tank 1 for defoaming and to accelerate the discharge of high-temperature water vapor from the medicine heating tank 1. The inner tube 201 is used to receive the high-temperature water vapor discharged from the medicine heating tank 1. The inner tube 201 is nested inside the outer tube 202. The high-temperature water vapor exchanges heat with the cold air passing through the outer tube 202 in the inner tube 201 to achieve cooling and condensation. The air-cooling component structure can serve as a pipeline for air to enter the medicine heating tank, and can also condense and exchange heat for the high-temperature water vapor in the inner tube. It is also a combined component that simplifies the structure of the medicine concentrator.

[0039] like Figure 1 As shown, the air inlet of the inner tube of the air-cooled component is connected to the defoaming cylinder 3 through the main exhaust pipe 5, and the defoaming cylinder 3 and the medicine heating tank 1 are connected through the auxiliary exhaust pipe 4. The air outlet of the inner tube 201 of the air-cooled component is connected to a water-cooled component.

[0040] Specifically, the inner tube 201 of the air-cooled component is part of the combined condensation air-cooled structure. High-temperature water vapor and residual foam generated by the heated and concentrated medicinal liquid in the medicine heating tank 1 enter the defoaming cylinder 3 through the auxiliary exhaust pipe 4. After defoaming is completed in the defoaming cylinder 3, the high-temperature water vapor enters the inner tube 201 of the air-cooled component through the main exhaust pipe 5. Primary condensation occurs in the inner tube 201, initially cooling the steam. Then, the steam is passed into a water-cooled component connected to the outlet of the inner tube 201 for secondary condensation. The air-cooled component effectively reduces the temperature of the high-temperature water vapor just blown out of the medicine heating tank during the water vapor transmission process, shortening the water vapor cooling time.

[0041] like Figure 2 As shown, the wind pressure defoaming structure includes a fan 11. The air inlet of the outer pipe 202 of the air-cooled component is connected to the fan 11 through the main air pipe 12, and the air outlet of the outer pipe 202 of the air-cooled component is connected to the liquid heating tank 1 through the auxiliary air pipe 13.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the air supply duct of the wind pressure defoaming structure includes a main air duct 12, an outer pipe 202 of the air-cooled component, and a secondary air duct 13. The fan 11 is fixed inside the housing below the medicine heating tank using a fixed bracket and is connected to the main air duct 12. The air generated by the fan 11 is introduced into the outer pipe 202 of the air-cooled component through the main air duct 12 connected to the air inlet end of the outer pipe of the air-cooled component. The air introduced into the outer pipe 202 of the air-cooled component enters the medicine heating tank 1 through the secondary air duct 13. The air introduced into the medicine heating tank 1 blows towards the surface of the medicine in the tank, destroying the generated bubbles, and water vapor is introduced into the defoaming cylinder 3 through the secondary exhaust pipe 4 connected above the medicine heating tank, accelerating the discharge of water vapor from the medicine heating tank 1.

[0043] Preferably, the fan is a DC turbine fan. DC turbine fans are small in size, have a long lifespan, low noise, and are energy-saving. When used in a pharmaceutical liquid concentrator, they can reduce the fan's energy consumption and floor space.

[0044] At least two medicine liquid heating tanks are provided, and multiple air outlets are provided on the side wall of the outer tube 202 of the air-cooling component, which are connected to the medicine liquid heating tank 1 one by one through multiple auxiliary air ducts 13.

[0045] The liquid concentrate concentrator includes at least two liquid heating tanks 1. An air outlet is provided on the side wall of the outer pipe 202 of the air-cooling component, and it is connected to the auxiliary air pipe 13. The auxiliary air pipe 13 is connected to the liquid heating tank 1 in a one-to-one correspondence, so that air can enter the corresponding liquid heating tank.

[0046] Specifically, as shown in the figure, the air-cooled component 2 is a component shared by the air pressure defoaming structure and the combined condensation structure. The air generated by the fan 11 in the air pressure defoaming structure continuously enters the medicine heating tank 1 through the outer pipe 202 of the air-cooled component. The high-temperature water vapor and residual foam in the medicine heating tank 1 are blown into the defoaming cylinder 3 through the auxiliary exhaust pipe 13, where the residual foam is eliminated. The hot steam enters the inner pipe 201 of the air-cooled component through the main exhaust pipe 5, where it exchanges heat with the continuously flowing air in the outer pipe 202 of the air-cooled component. This can both cool and condense the hot steam in the inner pipe 202 of the air-cooled component and transfer heat to the air in the outer pipe of the air-cooled component, raising the temperature of the air about to enter the medicine heating tank 1. This reduces the impact of introducing cold air into the medicine heating tank 1 on the temperature inside the tank, realizes the reuse of heat, and reduces energy waste.

[0047] Furthermore, after foam is blown into the defoaming cylinder 3 from the medicine heating tank 1, the foam is broken up in the defoaming cylinder 3 and becomes medicine liquid, which flows into the foam liquid pipe 14 connected to the outlet end of the defoaming cylinder.

[0048] Preferably, the defoaming cylinder 3 can be composed of a guide plate, an exhaust port, a wave deflector, etc. These structures can guide the movement of bubbles in the liquid, promote the gradual aggregation and detachment of bubbles from the liquid, and destroy the bubbles to complete the recovery of the medicine. The middle side wall of the defoaming cylinder 3 is connected to a secondary exhaust pipe 4 for receiving high-temperature water vapor and residual foam in the tank. The high-temperature water vapor enters the inner pipe 201 of the air-cooling component through the main exhaust pipe 5 connected to the upper side wall of the defoaming cylinder. The medicine generated after the residual foam is defoamed flows into the foam liquid pipe 14 through the liquid outlet connected to the bottom of the defoaming cylinder 3.

[0049] like Figure 1 and Figure 6 As shown, the combined condensation structure also includes a water-cooling component located below the liquid heating tank 1. The water-cooling component includes a cold water tank 6, a steam condensing pipe 15 located inside the cold water tank and connected to the air outlet of the inner tube of the air-cooling component, a vacuum box 7 connected to the end of the steam condensing pipe for retaining condensate, and a vacuum pump 9 connected to the vacuum box 7 for providing negative pressure.

[0050] The steam generated by the medicine heating tank 1 undergoes primary condensation in the air-cooled assembly and then enters the steam condenser pipe 15 of the water-cooled assembly, which is connected to the air outlet of the air-cooled assembly, for secondary condensation. The water-cooled assembly includes a cold water tank 6, with a cold water inlet pipe 16 connected to the lower side wall and a cold water outlet pipe 17 connected to the upper side wall, to maintain a sufficiently low water temperature in the cold water tank, thereby performing secondary condensation on the steam in the steam condenser pipe.

[0051] A second outlet pipe 18 is also provided below the side wall of the cold water tank. This pipe is not needed during normal condensation. When it is necessary to completely drain the water from the cold water tank, the valve of the second outlet pipe 18 can be opened to drain the water. The steam condenser pipes are stacked in a circulating manner within the cold water tank, facilitating the continuous flow of high-temperature steam and maximizing the flow path. This allows for sufficient heat exchange with the water in the cold water tank, enabling the high-temperature steam to condense as completely as possible.

[0052] After high-temperature steam exchanges heat and condenses with the cold water in the cold water tank 6 within the steam condenser pipe 15, the resulting condensate flows into the vacuum chamber 7 through a condensate outlet pipe 19 that passes through the side wall of the cold water tank. The condensate outlet pipe 19 is also connected to the side wall of the vacuum chamber 7. The vacuum chamber 7 is fixed below the cold water tank 6, and a condensate outlet pipe 20 is connected to the bottom of the vacuum chamber for discharging the condensate. The cold water tank outlet pipe, the second outlet pipe, and the condensate outlet pipe 20 are all connected to the main drain pipe 21 to discharge wastewater to the outside. An exhaust gas outlet pipe for transferring excess gas is also installed above the side wall of the vacuum chamber. The end of the exhaust gas outlet pipe is connected to a filter 8, where the excess gas is filtered and then discharged through a vacuum pump 9.

[0053] like Figure 3 and Figure 4 As shown, the wind pressure defoaming high-efficiency concentrator also includes a medicine circulation unit. The medicine circulation unit includes a hot water circulation pump 26, a main circulation pipe 22 connected to the hot water circulation pump 26, a secondary circulation pipe 23 connected to the bottom of the medicine heating tank, and a defoaming cylinder 3 connected to the medicine heating tank through a secondary exhaust pipe. The secondary circulation pipe 23 and the foam liquid pipe 14 connected to the liquid outlet of the defoaming cylinder are respectively connected to the main circulation pipe 22.

[0054] The liquid circulation unit also includes a main return pipe 24 connected to a hot water circulation pump. The main return pipe is connected to a secondary return pipe 25, and the outlet end of the secondary return pipe is connected to the upper part of the liquid heating tank.

[0055] The liquid medicine first enters the liquid medicine heating tank 1 through the liquid medicine inlet valve 10 set at the top of the tank. The heating coil fixed at the bottom of the heating tank heats the liquid medicine. The liquid medicine flows into the main circulation pipe 24 through the auxiliary circulation pipe 23 connected to the bottom of the tank. The outlet end of the defoaming cylinder 3 at the top of the tank is also connected to the foam liquid pipe 14. The liquid medicine generated by the foam after defoaming in the defoaming cylinder 3 flows into the foam liquid pipe 14. The liquid medicine also flows into the main circulation pipe 22 through the foam liquid pipe 14. The main circulation pipe 22 is connected to the inlet of the hot water circulation pump 26.

[0056] The hot water circulation pump 26 pumps the liquid medicine flowing back from the main circulation pipe 22 into the main return pipe 24, and finally back into the liquid medicine heating tank 1. Specifically, the auxiliary return pipe 25, connecting the main return pipe 24 and the upper part of the liquid medicine heating tank, distributes the liquid medicine to the rotating nozzles inside the liquid medicine heating tank. The liquid medicine is sprayed onto the tank wall through the rotating nozzles, increasing the contact area between the liquid medicine and the tank, which helps to effectively remove dissolved gases, volatile components and other impurities, and promotes the efficiency of liquid medicine concentration. At the same time, the circulating sprayed liquid medicine is in a flowing state. The flowing state can make the temperature of the liquid medicine more uniform throughout the concentration process. If the liquid medicine is in a static state, local overheating or undercooling will occur, resulting in uneven concentration of the liquid medicine. Moreover, some liquid medicine is prone to precipitation in a static state, which can cause blockage of the concentration equipment or even sticking to the pot.

[0057] like Figure 5 As shown, the wind pressure defoaming high-efficiency concentrator also includes an automatic cleaning unit. The automatic cleaning unit includes a cleaning water inlet pipe 27 for connecting to an external water source. The water outlet end of the cleaning water inlet pipe is connected to the upper part of the defoaming cylinder 3, and the lower part of the defoaming cylinder is provided with a liquid outlet end. The liquid outlet end is connected to a downwardly extending foam liquid pipe 14.

[0058] Specifically, the cleaning inlet pipe 27 is connected to an external tap water inlet. The tap water pressure forces the cleaning water into the defoaming cylinder 3 via the cleaning inlet pipe 27. The cleaning inlet pipe 27 extends upwards from the inlet to the upper end of the defoaming cylinder 3. When cleaning the defoaming cylinder 3, the cleaning water flows through the foam liquid pipe 14 connected to the outlet end of the defoaming cylinder into the main circulation pipe 22. Both the inlet end of the cleaning inlet pipe and the inlet end of the water-cooling assembly's water-cooling box are connected to the external tap water inlet.

[0059] During the cleaning process, the cleaning water sequentially enters the main circulation pipe 22 through the cleaning inlet pipe 27, the defoaming cylinder 3, and the foam liquid pipe 14. Then, driven by the hot water circulation pump 26, it enters the medicine heating tank 1 along the main return pipe 24 and the auxiliary return pipe 25. Finally, it enters the main circulation pipe 22 through the auxiliary circulation pipe 23 connected to the bottom of the tank for circulating cleaning.

[0060] Specifically, after the cleaning water cleans the defoaming cylinder 3, it enters the main circulation pipe 22 through the foam liquid pipe 14 to clean the main circulation pipe 22, and then connects to the hot water circulation pump 26. Driven by the hot water circulation pump 26, the cleaning water enters the main return pipe 24 and the secondary return pipe 25 for cleaning, and is sprayed onto the wall of the medicine heating tank 1 through a rotating nozzle connected to the secondary return pipe 25 to clean the medicine heating tank 1. The cleaning water then flows into the secondary circulation pipe 23 and converges back into the main circulation pipe 22, returning to the hot water circulation pump 26 to complete one cycle. Then, the cleaning water is circulated according to the circulation process of the medicine circulation unit. After cleaning the pipeline and the medicine heating tank 1, the cleaning water is discharged from the equipment.

[0061] As a specific embodiment of the present invention, the wind pressure defoaming high-efficiency concentrator includes two horizontally arranged liquid heating tanks 1, two auxiliary circulation pipes 23 respectively connected to the bottom of the two liquid heating tanks, two auxiliary return pipes 25 connected to the top of the two liquid heating tanks and the main return pipe 24, two auxiliary exhaust pipes 4 connected to the middle side wall of the defoaming cylinder 3 and the top of the liquid heating tank, and two auxiliary air pipes 13 connected to the upper side wall of the outer pipe 202 of the air-cooling component and the top of the liquid heating tank.

[0062] The following describes the complete working process of the wind pressure defoaming high-efficiency thickener described in the embodiments of the present invention.

[0063] When the wind-pressure defoaming high-efficiency thickener is working, the medicine to be concentrated is first introduced into the medicine heating tank 1 through the medicine inlet valve 10 located at the top of the medicine heating tank 1. After the medicine is completely added into the medicine heating tank 1, the medicine inlet valve 10 is closed, and the heating coil located at the bottom of the medicine heating tank is turned on to heat the medicine. At the same time, the medicine is collected into the main circulation pipe 22 through the secondary circulation pipe 23 connected to the drain port at the bottom of the medicine heating tank. The main circulation pipe 22 is connected to the inlet of the hot water circulation pump 26. The hot water circulation pump 26 pumps the medicine into the main return pipe 24, and then distributes it through the secondary return pipe 25 to the rotating nozzle connected to the secondary return pipe 25 inside the medicine heating tank 1. The nozzle sprays the medicine onto the inner wall of the medicine heating tank 1 to increase the evaporation area and ensure that the temperature of the medicine is more uniform during the evaporation process, thus completing the circulation process of the medicine.

[0064] During the circulation of the medicinal liquid, the fan 11, fixed inside the box below the medicinal liquid heating tank 1, introduces air into the air-cooling component's outer pipe 202 through the main air pipe 12 connected to the outer pipe 202 of the air-cooling component, and then introduces the air into the medicinal liquid heating tank 1 through the auxiliary air pipe 13 connected to the outer pipe 202 of the air-cooling component. The introduced air accelerates the airflow velocity inside the tank, speeds up the discharge of high-temperature water vapor, and simultaneously impacts and breaks down the foam generated on the surface of the medicinal liquid, thus assisting in defoaming and improving evaporation efficiency.

[0065] The high-temperature steam and residual foam blown out of the medicine heating tank 1 enter the defoaming cylinder 3 through the auxiliary exhaust pipe 4 connected to the top of the medicine heating tank. After the residual foam is eliminated in the defoaming cylinder 3, the resulting medicine flows into the main circulation pipe 22 through the foam liquid pipe 14. The high-temperature steam enters the inner pipe 201 of the air-cooling component through the main exhaust pipe 5, where it exchanges heat with the air introduced into the outer pipe 202 of the air-cooling component. This cools the steam in the inner pipe 201 of the air-cooling component and heats the air to be introduced into the tank in the outer pipe 202 of the air-cooling component. This achieves heat reuse and reduces the impact of cold air on the temperature inside the medicine heating tank 1.

[0066] The steam from the air-cooled assembly is then introduced into the steam condenser tube 15 of the water-cooled assembly. The steam condenser tube 15 is stacked and circulated within the water-cooled tank 6 of the water-cooled assembly. The water in the water-cooled tank 6 is kept in contact with the outside water to maintain a temperature sufficient for condensation of the steam. The steam exchanges heat with the circulating cold water in the water-cooled tank 6 within the steam condenser tube 15. The condensate generated after condensation in the steam condenser tube 15 is discharged through the condensate outlet pipe 19 to the vacuum chamber 7 fixed at the bottom of the water-cooled tank 6. Excess gas in the steam condenser tube 15 is introduced into the vacuum chamber 7 and then through the exhaust gas outlet pipe on the side wall of the vacuum chamber to the filter 8. The filtered gas is then extracted and discharged from the equipment under the negative pressure of the vacuum pump 9.

[0067] After the medicine solution is concentrated, it is discharged through the outlet at the bottom of the medicine heating tank. Cleaning water is then pumped into the defoaming cylinder through the cleaning water inlet pipe connected to the top of the defoaming cylinder to clean it. The cleaning water flows into the main circulation pipe through the foam liquid pipe connected to the outlet end of the defoaming cylinder and is pumped to the main return pipe. The rotating nozzle connected to the auxiliary return pipe cleans the medicine heating tank. The cleaning water is then collected into the main circulation pipe through the auxiliary circulation pipe connected to the bottom of the tank and re-entered by the hot water circulation pump for circulation cleaning inside the tank. After cleaning, the cleaning water is discharged through the outlet valve located at the bottom of the tank.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
