Description

Technical Field

[0001] This invention relates to the field of equipment cleaning technology, specifically to equipment cleaning systems and their control methods, devices, equipment, and media. Background Technology

[0002] In the industrial production of fluid foods, cleaning in place (CIP) systems are commonly used for on-site cleaning, especially in highly automated food production and processing processes such as dairy products, beverages, juices, and jams. Therefore, the design of CIP systems directly affects the production efficiency and energy consumption of the entire production system and is an important part of the production system.

[0003] Currently, CIP systems typically use a 5-tank system, namely one acid tank, one alkali tank, one hot water tank, one clean water tank, and one recovery tank. Equipment cleaning requires multiple cleaning processes, including initial water rinsing, alkali cleaning, intermediate water rinsing, acid cleaning, final water rinsing, and hot water cleaning. Among these, the intermediate and final water rinsing require cleaning tanks to clean each cleaning step, and the water is recycled to the recovery tank after rinsing. This results in low water resource utilization and high water consumption. Summary of the Invention

[0004] In view of this, the present invention provides an equipment cleaning system and its control method, device, equipment and medium to solve the problems of low water resource utilization and high water consumption in the CIP system of related technologies during equipment cleaning.

[0005] In a first aspect, the present invention provides an equipment cleaning system, comprising: an acid tank, an alkali tank, a clean water tank, and a hot water tank; the equipment cleaning system further comprises: a first recovery tank, a second recovery tank, and a third recovery tank, wherein...

[0006] The first recovery tank is used to perform the first rinse of the target cleaning equipment;

[0007] The second recovery tank is used to perform a second rinse on the target cleaning equipment after the first rinse is completed, and the liquid after the second rinse is recovered to the first recovery tank;

[0008] The alkali tank is used to perform a third rinse on the target cleaning equipment after the second rinse, and the liquid after the third rinse is recycled to the second recovery tank. After the third rinse is completed, the target cleaning equipment is rinsed a fourth time, and the liquid after the fourth rinse is recycled to the alkali tank.

[0009] The third recovery tank is used to perform a fifth rinse on the target cleaning equipment after the fourth rinse, and the liquid after the fifth rinse is recovered to the alkali tank or the second recovery tank. After the fifth rinse, the target cleaning equipment is rinsed a sixth time, and the liquid after the sixth rinse is recovered to the second recovery tank.

[0010] The acid tank is used to perform a seventh rinse on the target cleaning equipment after the sixth rinse, and the liquid after the seventh rinse is recycled to the third recovery tank. After the seventh rinse, the target cleaning equipment is rinsed an eighth time, and the liquid after the eighth rinse is recycled to the acid tank.

[0011] The clean water tank is used to perform a ninth rinse on the target cleaning equipment after the eighth rinse, and the liquid after the ninth rinse is recycled to the acid tank or the third recovery tank.

[0012] The hot water tank is used to perform a tenth rinse on the target cleaning equipment after the ninth rinse, and the liquid after the tenth rinse is recycled to the hot water tank or the third recycling tank.

[0013] By setting up three recovery tanks, the intermediate water used in the equipment cleaning process is recovered in stages and multiple times, allowing water resources to be reused multiple times, thus saving water consumption. Furthermore, by using the alkaline liquid recovered in the second recovery tank and the acidic liquid recovered in the third recovery tank to rinse the equipment before alkaline and acid washing, the step of rinsing with clean water before alkaline and acid washing in related technologies is eliminated, avoiding water waste. It also maintains that the residual liquid in the equipment is alkaline or acidic before alkaline or acid washing, thereby further improving the cleaning efficiency of alkaline or acid washing. In addition, the recovery of the liquid after acid washing and alkaline washing through different recovery tanks avoids the problem of directly recycling it to the acid and alkali tanks and affecting the concentration of the cleaning solution in the acid and alkali tanks, further ensuring the cleaning efficiency of subsequent alkaline or acid washing of other equipment, shortening equipment cleaning time, and improving equipment production efficiency.

[0014] In one optional embodiment, the equipment cleaning system further includes:

[0015] The cleaning system is used to filter the liquid recovered each time and replenish the filtered liquid to the acid tank, alkali tank, hot water tank, first recovery tank, second recovery tank and third recovery tank respectively.

[0016] By setting up a cleaning system to filter the liquid after each rinse, residual production products and impurities in the rinsing liquid can be removed, ensuring that the liquid recovered to the acid tank, alkali tank, hot water tank, first recovery tank, second recovery tank and third recovery tank is clean and safe, and further ensuring the cleaning effect of subsequent equipment.

[0017] In one optional embodiment, the equipment cleaning system further includes: a water supply pipeline and a cleaning pipeline;

[0018] The water supply pipeline is connected to the inlet of the acid tank, alkali tank, hot water tank and clean water tank respectively, and is used to replenish water to the acid tank, alkali tank, hot water tank and clean water tank;

[0019] The input end of the cleaning pipeline is connected to the output ends of the acid tank, alkali tank, hot water tank, clean water tank, first recovery tank, second recovery tank and third recovery tank respectively, and the output end is connected to the target cleaning equipment for delivering rinsing liquid to the target cleaning equipment.

[0020] By setting up a water supply pipeline to provide water to the equipment cleaning system, a unified and automated water replenishment system is achieved. Furthermore, by setting up a cleaning pipeline to uniformly supply rinsing liquid to the equipment, the equipment and multiple tanks of the equipment cleaning system are not connected separately, thus improving the efficiency of rinsing liquid delivery.

[0021] In one optional embodiment, the equipment cleaning system further includes: a heating system and / or a cleaning fluid replenishment pipeline, wherein,

[0022] The heating system is used to heat the various components of the equipment cleaning system;

[0023] The cleaning fluid replenishment pipeline is connected to the replenishment port of the acid tank and the alkali tank respectively, and is used to replenish the acid tank with acidic cleaning fluid and the alkali tank with alkaline cleaning fluid.

[0024] By setting up a heating system to heat each component of the entire equipment cleaning system, heating control of different structures in the system can be achieved, the heating process is more flexible and the heating efficiency is high, which can effectively reduce the temperature redundancy of traditional CIP systems and improve the cleaning efficiency of the equipment by heating the rinsing liquid.

[0025] In a second aspect, embodiments of the present invention provide a control method for an equipment cleaning system, wherein the equipment cleaning system is the equipment cleaning system described in the first aspect above and any optional embodiment thereof, and the method includes:

[0026] Upon receiving a cleaning instruction from the target cleaning equipment, the first recovery tank is controlled to perform the first rinse on the target cleaning equipment;

[0027] After the first rinse is completed, the second recovery tank is controlled to perform a second rinse on the target cleaning equipment, and the liquid from the second rinse is recovered to the first recovery tank;

[0028] After the second rinse, the alkaline tank is controlled to perform a third rinse on the target cleaning equipment, and the liquid after the third rinse is recovered to the second recovery tank. After the third rinse, the alkaline tank is controlled to perform a fourth rinse on the target cleaning equipment, and the liquid after the fourth rinse is recovered to the alkaline tank.

[0029] After the fourth rinsing is completed, the third recovery tank is controlled to perform a fifth rinsing on the target cleaning equipment, and the liquid after the fifth rinsing is recovered to the alkali tank or the second recovery tank. After the fifth rinsing is completed, the third recovery tank is controlled to perform a sixth rinsing on the target cleaning equipment, and the liquid after the sixth rinsing is recovered to the second recovery tank.

[0030] After the sixth rinse, the acid tank is controlled to perform a seventh rinse on the target cleaning equipment, and the liquid after the seventh rinse is recovered to the third recovery tank. After the seventh rinse, the acid tank is controlled to perform an eighth rinse on the target cleaning equipment, and the liquid after the eighth rinse is recovered to the acid tank.

[0031] After the eighth rinse, the clean water tank is controlled to perform a ninth rinse on the target cleaning equipment, and the liquid after the ninth rinse is recovered to the acid tank or the third recovery tank.

[0032] After the ninth rinse, the hot water tank is controlled to perform a tenth rinse on the target cleaning equipment, and the liquid from the tenth rinse is recycled to the hot water tank or the third recovery tank.

[0033] By utilizing the alkaline liquid recovered in the second recovery tank and the acidic liquid recovered in the third recovery tank for rinsing before alkaline and acid washing of the equipment, the step of rinsing with clean water before alkaline and acid washing in related technologies is eliminated, avoiding water waste. Furthermore, the residual liquid in the equipment is kept alkaline or acidic before alkaline and acid washing, thereby further improving the cleaning efficiency of alkaline or acid washing. In addition, the recovery of the liquid after acid and alkaline washing through different recovery tanks avoids the problem of directly returning it to the acid and alkali tanks and affecting the concentration of the cleaning solution in the acid and alkali tanks, further ensuring the cleaning efficiency of subsequent alkaline or acid washing of other equipment, shortening equipment cleaning time, improving equipment production efficiency, and allowing water resources to be reused multiple times, thus saving water consumption.

[0034] In one optional embodiment, the step of recovering the liquid after the fifth rinse to the alkali tank or the second recovery tank includes:

[0035] The conductivity of the liquid after the fifth rinse was measured.

[0036] When the conductivity is detected to be less than the first preset conductivity threshold, the liquid after the fifth flush is recycled to the second recycling tank;

[0037] When the conductivity is detected to be not less than the first preset conductivity threshold, the liquid after the fifth rinse is recycled to the alkali tank;

[0038] And / or, the step of recovering the liquid after the ninth rinse to the acid tank or the third recovery tank includes:

[0039] The conductivity of the liquid after the ninth rinse was measured.

[0040] When the conductivity is detected to be less than the second preset conductivity threshold, the liquid after the ninth flush is recycled to the third recycling tank;

[0041] When the conductivity is detected to be not less than the second preset conductivity threshold, the liquid after the ninth rinse is recycled to the acid tank;

[0042] And / or, the step of recycling the liquid after the tenth flush to the hot water tank or the third recycling tank includes:

[0043] The temperature of the liquid after the tenth rinse was measured;

[0044] When the temperature is detected to be higher than the preset temperature threshold, the liquid from the tenth rinse is recycled back to the hot water tank;

[0045] When the temperature is detected to be no greater than the preset temperature threshold, the liquid after the tenth rinse is recycled to the third recycling tank.

[0046] By detecting the conductivity and / or temperature of the intermediate liquid during the equipment rinsing process, the intermediate liquid can be accurately recovered, thereby reducing the impact of the recovered liquid on the concentration of the cleaning solution in the acid and alkali tanks and on the water temperature in the hot water tank, and further ensuring the cleaning efficiency of the equipment.

[0047] In an optional implementation, the method further includes:

[0048] The cleaning system is used to filter each recovered liquid.

[0049] The pH value and temperature of the liquid after filtration through the cleaning system are measured.

[0050] Based on the test results, the liquid filtered by the cleaning system is replenished to the acid tank, alkali tank, hot water tank, first recovery tank, second recovery tank and third recovery tank respectively.

[0051] By using a cleaning system to filter and monitor the pH and temperature of each recovered liquid, the system ensures the cleanliness and safety of the recovered liquid while achieving precise recovery and guaranteeing the cleaning efficiency of the entire equipment cleaning system.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] In existing CIP systems, the cleaning process involves rinsing with clean water between acid washing, alkaline washing, and heat disinfection. After rinsing with clean water, the water enters a recovery tank for rinsing before the equipment undergoes CIP cleaning. However, when the recovery tank reaches a high level, the water is drained, resulting in water waste.

[0072] To address the aforementioned problems, this invention provides a device cleaning system, such as... Figure 1 As shown, the equipment cleaning system includes: acid tank 101, alkali tank 102, clean water tank 103, and hot water tank 104. The system also includes: a first recovery tank 105, a second recovery tank 106, and a third recovery tank 107.

[0073] The first recovery tank 105 is used to perform the first rinse on the target cleaning equipment 112;

[0074] The second recovery tank 106 is used to perform a second rinse on the target cleaning equipment 112 after the first rinse is completed, and the liquid after the second rinse is recovered to the first recovery tank 105.

[0075] Alkali tank 102 is used to perform a third rinse on the target cleaning equipment 112 after the second rinse. The liquid after the third rinse is recycled to the second recovery tank 106. After the third rinse, the target cleaning equipment 112 is rinsed a fourth time. The liquid after the fourth rinse is recycled to alkali tank 102.

[0076] The third recovery tank 107 is used to perform a fifth rinse on the target cleaning equipment 112 after the fourth rinse. The liquid after the fifth rinse is recovered to the alkali tank 102 or the second recovery tank 106. After the fifth rinse, the target cleaning equipment 112 is rinsed a sixth time. The liquid after the sixth rinse is recovered to the second recovery tank 106.

[0077] Acid tank 101 is used to perform a seventh rinse on the target cleaning equipment 112 after the sixth rinse. The liquid after the seventh rinse is recycled to the third recovery tank 107. After the seventh rinse, the target cleaning equipment 112 is rinsed for the eighth time. The liquid after the eighth rinse is recycled to acid tank 101.

[0078] The clean water tank 103 is used to perform a ninth rinse on the target cleaning equipment 112 after the eighth rinse. The liquid after the ninth rinse is recycled to the acid tank 101 or the third recovery tank 107.

[0079] Hot water tank 104 is used to perform a tenth rinse on the target cleaning equipment 112 after the ninth rinse. The liquid after the tenth rinse is recycled to hot water tank 104 or third recovery tank 107.

[0080] By setting up three recovery tanks, the intermediate water used in the equipment cleaning process is recovered in stages and multiple times, allowing water resources to be reused multiple times and saving water consumption. Furthermore, by using the alkaline liquid recovered in the second recovery tank 106 and the acidic liquid recovered in the third recovery tank to rinse the equipment before alkaline and acid washing, the step of rinsing with clean water before alkaline and acid washing in related technologies is eliminated, avoiding waste of water resources. It also maintains that the residual liquid in the equipment is alkaline or acidic before alkaline or acid washing, thereby further improving the cleaning efficiency of alkaline or acid washing. In addition, the recovery of the liquid after acid washing and alkaline washing through different recovery tanks avoids the problem of directly recovering it to the acid tank and alkaline tank and affecting the concentration of the cleaning solution in the acid tank and alkaline tank, further ensuring the cleaning efficiency of subsequent alkaline or acid washing of other equipment, shortening the equipment cleaning time, and improving the production efficiency of the equipment.

[0081] Specifically, the acid tank 101, alkali tank 102, hot water tank 104, and clean water tank 103 are similar in structure to the existing CIP system. The acid tank 101 is used to store acid cleaning solution, the alkali tank 102 is used to store alkaline cleaning solution, the hot water tank 104 is used to store hot water for high-temperature disinfection, and the clean water tank 103 is used to store clean water.

[0082] In some alternative implementations, such as Figure 1 As shown, the above-mentioned equipment cleaning system also includes:

[0083] The cleaning system 108 is used to filter the liquid recovered each time and replenish the filtered liquid to the acid tank 101, alkali tank 102, hot water tank 104, first recovery tank 105, second recovery tank 106 and third recovery tank 107 respectively.

[0084] For example, the cleaning system 108 can be configured as a satellite cleaning system. When the satellite cleaning system needs cleaning, the required cleaning fluid is pumped into each tank of the above-mentioned equipment cleaning system. After cleaning by the satellite cleaning system, the cleaning fluid is pumped back to the equipment cleaning system through a circulation loop. The satellite cleaning system uses technologies such as bag filters or RO membrane filtration to filter impurities and residues in the liquid flowing into the satellite cleaning system, ensuring the cleanliness and safety of the recovered acid, alkali, hot water and other cleaning fluids.

[0085] By setting up a cleaning system 108 to filter the liquid after each rinse, residual production products and impurities in the rinsing liquid can be removed, ensuring that the liquid recovered to acid tank 101, alkali tank 102, hot water tank 104, first recovery tank 105, second recovery tank 106 and third recovery tank 107 is clean and safe, further ensuring the cleaning effect of subsequent equipment.

[0086] In some optional embodiments, the equipment cleaning system further includes: a water replenishment pipeline 109 and a cleaning pipeline 110; the water replenishment pipeline 109 is connected to the inlets of the acid tank 101, alkali tank 102, hot water tank 104 and clean water tank 103 respectively, for replenishing water to the acid tank 101, alkali tank 102, hot water tank 104 and clean water tank 103; the input end of the cleaning pipeline 110 is connected to the output ends of the acid tank 101, alkali tank 102, hot water tank 104, clean water tank 103, first recovery tank 105, second recovery tank 106 and third recovery tank 107 respectively, and the output end is connected to the target cleaning equipment 112 for delivering rinsing liquid to the target cleaning equipment 112.

[0087] Specifically, the water supply pipeline 109 supplies soft water to each tank, and the cleaning pipeline 110 delivers different rinsing liquids to the target cleaning equipment 112 at different cleaning stages. For example, it delivers the acid cleaning solution from the acid tank 101 during the acid washing stage and the alkaline cleaning solution from the alkaline tank 102 during the alkaline washing stage. The specific materials of the water supply pipeline 109 and the cleaning pipeline 110 can be selected according to actual needs. Usually, the cleaning pipeline 110 needs to be made of a pipe material that is resistant to acid and alkali corrosion and high temperature.

[0088] By setting up a water supply pipeline 109 to provide water to the equipment cleaning system, a unified and automated water supply is achieved. By setting up a cleaning pipeline 110 to uniformly supply rinsing liquid to the equipment, the equipment and multiple tanks of the equipment cleaning system are not connected separately, thus improving the efficiency of rinsing liquid delivery.

[0089] In some alternative implementations, such as Figure 1 As shown, the equipment cleaning system also includes: a heating system ( Figure 1 (not shown) and cleaning fluid replenishment pipeline 111, wherein,

[0090] The heating system is used to heat the various components of the equipment cleaning system;

[0091] The cleaning fluid replenishment pipeline 111 is connected to the replenishment port of acid tank 101 and alkali tank 102 respectively, and is used to replenish acidic cleaning fluid to acid tank 101 and alkaline cleaning fluid to alkali tank 102.

[0092] The specific material of the cleaning fluid replenishment pipeline 111 can be selected according to actual needs. Generally, the cleaning pipeline 110 needs to be selected to be resistant to acid and alkali corrosion. It should be noted that the cleaning fluid replenishment pipeline 111 and the heating system are optional parts of the equipment cleaning system. One of them can be set alone, or both can be set. In this embodiment of the invention, both are set as an example to improve the automation level and cleaning efficiency of the entire system.

[0093] Specifically, the aforementioned heating system can consist of multiple heating components, each corresponding to a specific part of the equipment cleaning system. For example, by configuring heating devices at five locations—alkali tank 102, acid tank 101, hot water tank 104, cleaning pipeline 110, and cleaning system 108—to heat the cleaning liquid, the large heating system on the centralized cleaning pressure line of the CIP system in related technologies is replaced with smaller, flexible heating systems such as tank self-circulation heating, the heating system of cleaning pipeline 110, and the heating system of cleaning system 108. This makes the heating process more flexible, increases heating efficiency, effectively reduces temperature redundancy in the CIP system, and improves cleaning efficiency. Furthermore, each heating system can be modularly designed, dynamically switching the heating method of the cleaning liquid based on energy costs such as steam, electricity, and natural gas, achieving optimal energy costs.

[0094] By setting up a heating system to heat each component of the entire equipment cleaning system, heating control of different structures in the system can be achieved, the heating process is more flexible and the heating efficiency is high, which can effectively reduce the temperature redundancy of traditional CIP systems and improve the cleaning efficiency of the equipment by heating the rinsing liquid.

[0095] In addition, in practical applications, a certain amount of nitric acid can be added to the hot water tank 104 to make it slightly acidic. This not only inhibits the growth of microorganisms, but also creates a certain acidity on the surface of the cleaned equipment after hot water disinfection, which inhibits the growth of microorganisms on the equipment surface and increases the standby time before the equipment is used. When the equipment is used, it can be rinsed with sterile water before production, which greatly reduces the cleaning cost of the production system.

[0096] According to an embodiment of the present invention, a control method embodiment for an equipment cleaning system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0097] This embodiment provides a control method for an equipment cleaning system, which can be used for, for example... Figure 1 The equipment cleaning system shown Figure 2 This is a flowchart of a control method for an equipment cleaning system according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0098] Step S201: Upon receiving a cleaning instruction from the target cleaning equipment, control the first recovery tank to perform a first rinse on the target cleaning equipment.

[0099] Specifically, taking dairy production as an example, after the production line finishes production, a cleaning command is sent to the equipment cleaning system. Upon receiving this command, the equipment cleaning system controls the outlet valve of the first recovery tank to open, and performs the first flushing of the entire production line according to the set flow rate. Figure 3 The process shown involves rinsing with water after production, and then directly discharging the rinse fluid after cleaning, also known as end-of-pipe discharge.

[0100] Step S202: After the first rinse is completed, control the second recovery tank to perform a second rinse on the target cleaning equipment, and recover the liquid after the second rinse to the first recovery tank.

[0101] Specifically, after the initial water rinse, the outlet valve of the second recovery tank is opened, and the entire production line is rinsed a second time according to the set flow rate. Figure 3 The initial cleaning is shown in the diagram. Then, the valve between the production line and the first recovery tank is opened to recover the cleaning rinsing solution to the first recovery tank for use as a post-production water rinse for the next production line.

[0102] Step S203: After the second rinsing is completed, the alkali tank is controlled to perform a third rinsing on the target cleaning equipment, and the liquid after the third rinsing is recovered to the second recovery tank. After the third rinsing is completed, the alkali tank is controlled to perform a fourth rinsing on the target cleaning equipment, and the liquid after the fourth rinsing is recovered to the alkali tank.

[0103] Specifically, after the initial cleaning, the outlet valve of the alkali tank is opened, and a third rinse is performed on the entire production line according to the set flow rate. Figure 3 The process involves flushing the production line with alkaline water, then opening the valve between the production line and the second recovery tank to recycle the rinsing solution back into the second recovery tank for the initial cleaning of the production line, thus achieving water resource reuse. After the alkaline flushing, the outlet valve of the alkaline tank is opened again to perform a fourth flush of the entire production line according to the set flow rate. Figure 3 The process involves alkali cleaning, followed by opening the valve between the production line and the alkali tank to return the cleaning solution to the alkali tank.

[0104] Step S204: After the fourth rinsing is completed, the third recovery tank is controlled to perform a fifth rinsing on the target cleaning equipment, and the liquid after the fifth rinsing is recovered to the alkali tank or the second recovery tank. After the fifth rinsing is completed, the third recovery tank is controlled to perform a sixth rinsing on the target cleaning equipment, and the liquid after the sixth rinsing is recovered to the second recovery tank.

[0105] It should be noted that before the entire equipment cleaning system is used for the first time, a certain amount of clean water is injected into the first, second, and third recovery tanks. During the cleaning process, the liquid level in each recovery tank is monitored. If the liquid level in each recovery tank is lower than the required amount for rinsing, clean water will be added to meet the needs of subsequent cleaning.

[0106] Specifically, after alkaline cleaning, the outlet valve of the third recovery tank is opened, and the entire production line is rinsed a fifth time according to the set flow rate. Figure 3 The process involves water-push alkali, followed by opening the valve between the production line and the second recovery tank to recycle the rinsing solution back to the second recovery tank for use in the next initial cleaning of the production line. Alternatively, the valve between the production line and the alkali tank can be opened to recycle the rinsing solution back to the alkali tank, achieving water resource reuse. After water-push alkali, the outlet valve of the third recovery tank is opened again to perform a sixth rinse of the entire production line according to the set flow rate. Figure 3 The intermediate water rinse is shown, and then the valve between the production line and the second recovery tank is opened to recover the rinse fluid after cleaning to the second recovery tank for the next initial cleaning of the production line.

[0107] By utilizing the weakly alkaline nature of the liquid in the secondary recovery tank, residual acid pickling liquid in the production line can be neutralized during the initial cleaning in the next production line cycle. The two-stage rinsing process in the alkaline tank ensures the effectiveness of the alkaline cleaning. Furthermore, by recovering the rinsing liquid from the two rinsing cycles to the secondary recovery tank and the alkaline tank respectively, the concentration of the cleaning solution in the alkaline tank is maintained, further ensuring the efficiency of alkaline cleaning. Maintaining alkalinity and a certain temperature in the secondary recovery tank not only inhibits microbial growth but also maintains the equipment's weak alkalinity and a certain preheating temperature during the next water rinse, improving the efficiency of alkaline cleaning and saving on alkaline cleaning costs.

[0108] Step S205: After the sixth rinsing, control the acid tank to perform a seventh rinsing on the target cleaning equipment, and recover the liquid after the seventh rinsing to the third recovery tank. After the seventh rinsing, control the acid tank to perform an eighth rinsing on the target cleaning equipment, and recover the liquid after the eighth rinsing to the acid tank.

[0109] Specifically, after the intermediate water flush, the outlet valve of the acid tank is opened, and the entire production line is flushed a seventh time according to the set flow rate. Figure 3 The acid flushing water is then used. Next, the valve between the production line and the third recovery tank is opened to recover the rinsing solution to the third recovery tank for use in the next production line intermediate water flushing or water-based alkali flushing, achieving water resource reuse. After the acid flushing water, the outlet valve of the acid tank is opened again to perform an eighth flushing of the entire production line according to the set flow rate. Figure 3The process involves acid cleaning, followed by opening the valve between the production line and the acid tank to recover the cleaning solution back into the acid tank for use in the next acid flushing or acid cleaning of the production line.

[0110] By utilizing the acid-washing characteristic of the liquid recovered in the third recovery tank, it is used in the water-push alkali and intermediate water rinsing processes to neutralize the alkaline liquid on the production line after alkali cleaning. The effectiveness of acid cleaning is ensured through a two-stage rinsing process in the acid tank. Furthermore, by recovering the rinsing liquid from the two rinsings to the third recovery tank and the acid tank respectively, the concentration of the cleaning solution in the acid tank is maintained, further ensuring acid cleaning efficiency. By maintaining acidity and a certain temperature in the third recovery tank, microbial growth is inhibited, and the equipment is kept weakly acidic and at a certain preheating temperature during the next water rinsing, improving acid cleaning efficiency and saving acid cleaning costs.

[0111] Step S206: After the eighth rinse, control the clean water tank to perform a ninth rinse on the target cleaning equipment, and recover the liquid after the ninth rinse to the acid tank or the third recovery tank.

[0112] Specifically, after acid cleaning, the outlet valve of the clean water tank is opened, and the entire production line is rinsed a ninth time according to the set flow rate. Figure 3 The final water rinse is shown. Then, the valve between the production line and the third recovery tank is opened to recover the rinse solution after cleaning to the third recovery tank. This solution is then used for the next production line intermediate water rinse or water-push alkali, realizing the reuse of water resources. Alternatively, the valve between the production line and the acid tank is opened to recover the rinse solution after cleaning to the acid tank for the next acid cleaning or acid push water.

[0113] Step S207: After the ninth rinse, control the hot water tank to perform a tenth rinse on the target cleaning equipment, and recover the liquid after the tenth rinse to the hot water tank or the third recovery tank.

[0114] Specifically, after the final water rinse, the outlet valve of the hot water tank is opened, and the entire production line is rinsed a tenth time according to the set flow rate. Figure 3 The process involves heat disinfection, followed by opening the valve between the production line and the third recovery tank to recycle the cleaning solution to the third recovery tank for use in the next production line for intermediate water flushing or water-push alkali, thus achieving water resource reuse. Alternatively, the valve between the production line and the hot water tank can be opened to recycle the cleaning solution to the hot water tank for use in the next production line heat disinfection.

[0115] By utilizing the alkaline liquid recovered in the second recovery tank and the acidic liquid recovered in the third recovery tank for rinsing before alkaline and acid washing of the equipment, the step of rinsing with clean water before alkaline and acid washing in related technologies is eliminated, avoiding water waste. Furthermore, the residual liquid in the equipment is kept alkaline or acidic before alkaline and acid washing, thereby further improving the cleaning efficiency of alkaline or acid washing. In addition, the recovery of the liquid after acid and alkaline washing through different recovery tanks avoids the problem of directly returning it to the acid and alkali tanks and affecting the concentration of the cleaning solution in the acid and alkali tanks, further ensuring the cleaning efficiency of subsequent alkaline or acid washing of other equipment, shortening equipment cleaning time, improving equipment production efficiency, and allowing water resources to be reused multiple times, thus saving water consumption.

[0116] In some optional embodiments, step S204 above, in which the liquid after the fifth rinse is recovered to the alkali tank or the second recovery tank, specifically includes:

[0117] Step S2041: The conductivity of the liquid after the fifth rinse is measured.

[0118] Step S2042: When the conductivity is detected to be less than the first preset conductivity threshold, the liquid after the fifth rinse is recycled to the second recycling tank.

[0119] Step S2043: When the conductivity is detected to be not less than the first preset conductivity threshold, the liquid after the fifth rinse is recycled to the alkali tank.

[0120] Specifically, since the stronger the alkalinity of the solution, i.e., the higher the pH value, the greater the conductivity, it can be determined whether the solution meets the conductivity requirements corresponding to the pH value of the alkaline cleaning solution in the alkaline tank by detecting the conductivity of the rinsed liquid in the production line. The first preset conductivity threshold can be set according to the alkaline cleaning requirements of the target cleaning equipment. For example, the first preset conductivity threshold can be 50 S / m. This is just an example, and the present invention is not limited thereto.

[0121] In some optional embodiments, step S206 above, in which the liquid after the ninth rinse is recycled to the acid tank or the third recovery tank, specifically includes:

[0122] Step S2061: The conductivity of the liquid after the ninth rinse is measured.

[0123] Step S2062: When the conductivity is detected to be less than the second preset conductivity threshold, the liquid after the ninth rinse is recycled to the third recycling tank.

[0124] Step S2063: When the conductivity is detected to be not less than the second preset conductivity threshold, the liquid after the ninth rinse is recycled to the acid tank.

[0125] Specifically, since the stronger the acidity of the solution, i.e. the lower the pH value, the greater the conductivity, it can be determined whether the conductivity of the rinsed liquid in the production line meets the conductivity requirements corresponding to the pH value of the acidic cleaning solution in the acid tank by detecting the conductivity of the solution. The second preset conductivity threshold can be set according to the acid cleaning requirements of the target cleaning equipment. For example, the second preset conductivity threshold can be 20 S / m. This is just an example, and the present invention is not limited thereto.

[0126] In some optional embodiments, step S207 above, in which the liquid after the tenth rinse is recycled to a hot water tank or a third recycling tank, specifically includes:

[0127] Step S2071: The temperature of the liquid after the tenth rinse is detected.

[0128] Step S2072: When the temperature is detected to be greater than the preset temperature threshold, the liquid after the tenth rinse is recycled to the hot water tank.

[0129] Step S2073: When the detected temperature is not greater than the preset temperature threshold, the liquid after the tenth rinse is recycled to the third recycling tank.

[0130] Specifically, the preset temperature threshold can be set according to the heat disinfection requirements of the target cleaning equipment. For example, the preset temperature threshold can be 80°C. This is just an example, and the present invention is not limited thereto.

[0131] By detecting the conductivity and / or temperature of the intermediate liquid during the equipment rinsing process, the intermediate liquid can be accurately recovered, thereby reducing the impact of the recovered liquid on the concentration of the cleaning solution in the acid and alkali tanks and on the water temperature in the hot water tank, and further ensuring the cleaning efficiency of the equipment.

[0132] In some optional implementations, the above method further includes:

[0133] Step S208: Filter the liquid recovered each time using a cleaning system.

[0134] Step S209: Detect the pH value and temperature of the liquid after it has been filtered by the cleaning system.

[0135] Step S210: Based on the detection results, the liquid filtered by the cleaning system is replenished to the acid tank, alkali tank, hot water tank, first recovery tank, second recovery tank and third recovery tank respectively.

[0136] Specifically, before each recovery of liquid, the valves at the input ends of the production line and the cleaning system are opened to allow the liquid to pass through the filtration system. The conductivity and temperature of the filtered liquid are then measured to determine which tank's requirements are met. The liquid is then transferred to that tank. For example, if the conductivity of the liquid meets the requirements of the acid tank, it is recycled there. This invention is not limited to this. This achieves the reuse and multiple applications of water resources, and enables detailed optimization and control of the system, improving cleaning efficiency and reducing cleaning costs.

[0137] By using a cleaning system to filter and monitor the pH and temperature of each recovered liquid, the system ensures the cleanliness and safety of the recovered liquid while achieving precise recovery and guaranteeing the cleaning efficiency of the entire equipment cleaning system.

[0138] The specific control process of the equipment cleaning system provided in this embodiment of the invention will be described in detail below with reference to specific application examples.

[0139] like Figure 3 As shown, the equipment cleaning system provided in this embodiment of the invention adopts an 8-tank system, namely an acid tank, an alkali tank, a hot water tank, a clean water tank, a primary recovery tank (the aforementioned third recovery tank), a secondary recovery tank (the aforementioned second recovery tank), a tertiary recovery tank (the aforementioned first recovery tank), and a satellite cleaning tank (the aforementioned cleaning system). The equipment cleaning process involves multiple cleaning steps, including initial water rinsing, alkali cleaning, intermediate water rinsing, acid cleaning, final water rinsing, and heat disinfection. During cleaning, the clean water is reused four times according to the program control. Furthermore, the primary recovery tank is kept weakly acidic and at a certain temperature, the secondary recovery tank is kept weakly alkaline and at a certain temperature, and the hot water tank is kept at a certain acidity, which can effectively improve cleaning efficiency and reduce cleaning losses.

[0140] Heating devices are installed in five locations, including the alkali tank, acid tank, hot water tank, cleaning pipeline, and cleaning system, to heat the cleaning liquid. The previous large heating system concentrated on the cleaning pipeline is replaced with a small, flexible heating system such as tank self-circulation heating, which makes the heating process more flexible, the heating efficiency higher, effectively reduces the temperature redundancy of the CIP system, and improves the cleaning efficiency.

[0141] Figure 3The terms "acid-push-water," "alkali-push-water," and "water-push-acid" refer to the processes after alkali and acid washing cycles. For example, after alkali washing, the equipment and pipes are filled with alkali. Water is then used to push the alkali out of the equipment and pipes. Similarly, if acid washing is needed after water has filled the equipment, acid is used to push the water out of the equipment and pipes before acid washing can proceed. This ensures that the acid washing temperature and concentration meet the cleaning requirements, and reduces the risk of water directly entering the acid tank, which would lower the acid concentration and temperature. Through water reuse and detailed system control, cleaning efficiency is improved, cleaning costs are reduced, and cleaning waste is minimized.
