[0002] During the production process in the Maotai distillery, it is necessary to clean the site and wash the distillation tools. Workers generally use a direct water hose to rinse the equipment, which not only results in a huge amount of water consumption for cleaning, but also directly disrupts the originally stable microbial environment in the workshop because tap water is used repeatedly for rinsing every shift. Ultimately, this is not conducive to brewing baijiu with a consistent flavor. Utility Model Content

[0003] Based on this, a cleaning device and cleaning system are provided to solve the problems of large water consumption and inability to guarantee a stable microbial environment in existing cleaning workshops.

The first water tank is used to store circulating water. The outlet of the first water tank is connected to the inlet of the filter assembly, and the outlet of the filter assembly is connected to the water-using equipment, forming a circulating water purification supply path. The inlet end of the first pipe is used to recycle the used circulating water, and the outlet end of the first pipe is connected to the inlet end of the first water tank to form a wastewater recycling flow path for the circulating water. The power unit is configured to provide power for fluid transport in the clean water supply path and the wastewater recovery path.

[0019] A cleaning device, see Figure 1 and Figure 2 The cleaning device, used for filtering and transporting circulating water, includes a power unit, a filter assembly 1, a first water tank 2, a first pipe 3, and a water-using device 4. The filter element of the filter assembly 1 includes a multi-layer physical filtration structure with progressively increasing filtration accuracy from the inlet to the outlet. The first water tank 2 is used to store circulating water. The outlet of the first water tank 2 is connected to the inlet of the filter assembly 1, and the outlet of the filter assembly 1 is connected to the water-using device 4, forming a clean water supply path for circulating water. The inlet of the first pipe 3 is used to recycle used circulating water, and the outlet of the first pipe 3 is connected to the inlet of the first water tank 2, forming a wastewater recycling path for circulating water. The power unit is configured to provide power for fluid transport in the clean water supply path and the wastewater recycling path.

[0020] This solution comprises a clean water supply path and a wastewater recycling path. The combination of these two paths allows for the reuse of circulating water, thereby effectively saving cleaning water. Furthermore, the filter component 1 is a multi-layer physical filtration structure that filters out only impurities in the circulating water without disrupting the microbial environment within it. This allows the solution to be used in scenarios requiring both cleaning and maintenance of the microbial environment. During use, the circulating water flows sequentially through the first water tank 2, the filter component 1, and the water-using device 4 to form the clean water supply path. The circulating water also flows sequentially through the first pipe 3 and the first water tank 2 to form the wastewater recycling path.

[0021] Specifically, the clean and microbial environment achieved by this solution can be applied in various scenarios, such as liquor brewing, beer brewing, soy sauce brewing, vinegar brewing, dairy product fermentation, and microbial fermentation in the biotechnology and pharmaceutical industries.

[0022] In some embodiments, see Figure 1 and Figure 2 The filter assembly 1 includes at least two filters 11 arranged in series, and each filter assembly 1 is equipped with a filter element. In this way, the filters 11 remove impurities from the circulating water through a multi-layer physical filtration structure. The arrangement of at least two filters 11 in series effectively improves the filtration efficiency and extends the replacement time of the filter elements in the filter assembly 1.

[0023] Specifically, for multiple filters 11 connected in series, the filter elements of different filters 11 can be set differently. Taking two filters 11 as an example: the filter element of the first filter 11 closer to the first water tank 2 uses a coarser multi-layer physical filtration structure, while the filter element of the second filter 11 farther away from the first water tank 2 uses a finer multi-layer physical filtration structure. This allows the first filter 11, into which the circulating water first enters, to remove large particulate impurities and flocculants, preventing them from entering the subsequent system and deteriorating, thus affecting the microbial environment. The second filter 11, into which the circulating water enters later, is specifically used to remove finer bacterial fragments, fine sand particles, etc., ensuring the clarity of the effluent.

[0024] Specifically, for multiple filters 11 connected in series, the filter element of each filter 11 can be set to be the same. This makes it easier to replace the filter element, reduces the types of filter elements in stock, and also reduces the time spent identifying the type of filter element when replacing the filter element.

[0025] In some embodiments, the multi-layer physical filtration structure includes a pretreatment layer, a coarse particle layer, a fine particle layer, and a fine filter layer. Thus, the layered multi-layer physical filtration structure achieves a multi-layer filtration effect for circulating water, effectively removing suspended solids and particles from the circulating water.

[0026] In some embodiments, the pretreatment layer includes precipitated starch, the coarse particle layer includes coarse sand, the fine particle layer includes fine sand, and the fine filtration layer includes a mixture of fine sand and filter cotton. Thus, in a filter 11, circulating water sequentially passes through four layers of physical filtration structure, and the filtration process of the circulating water in the four layers of physical filtration structure is as follows: The pretreatment layer, as the first layer of circulating water filtration, is equipped with precipitated starch, which mainly intercepts larger suspended solids in the water, such as raw material residues, fibers, and some mycelia. In addition, starch swells in water, and its molecular chains can adsorb and entangle tiny suspended particles and colloidal substances in the water, forming larger "flocs" that are more easily captured in subsequent layers. The intercepted impurities form a filter cake on the surface and inside of the starch layer. This filter cake itself also becomes a filtration layer and can homogenize the water flow and reduce the load on subsequent layers. It effectively prevents large particles of impurities from directly clogging the subsequent sand layer, greatly extending the cleaning / replacement cycle of the entire filter element. The coarse-grained layer, as the second layer of the circulating water filter, is equipped with coarse sand to intercept small particulate impurities that pass through the starch layer, as well as the "flocculation" formed by the starch layer. The pores between its particles are more regular than those of the starch layer, enabling more stable deep filtration. It provides solid physical support for the upper starch layer, preventing it from being washed away or over-compressed by the water flow. At the same time, it also provides support for the fine sand in the lower layer. The fine particle layer, as the third layer of the circulating water filtration, is filled with fine sand for fine filtration. Through tiny pores, it can effectively capture most of the fine suspended particles in the water, including tiny sand grains, rust, and even finer organic debris. After passing through this layer, the solid impurities in the water have been basically removed, greatly reducing the burden on the last layer, the "fine sand and filter cotton mixture layer," and preventing the filter cotton from being quickly clogged. As the fourth layer of circulating water filtration, the fine filter layer contains a mixture of fine sand and filter cotton to remove extremely fine particles that the previous layers failed to capture. The mixture of fine sand and filter cotton forms a filter matrix with extremely low porosity and extremely tortuous and complex channels. This structure can capture impurities through multiple mechanisms such as sieving, interception, and adsorption, and the filtration effect is far superior to a single sand layer or cotton layer. Compared with pure filter cotton, the structure mixed with fine sand is less prone to compaction, maintains more pore space, and thus has a higher impurity holding capacity and extends service life.

[0027] In summary, the four-layer structure of the filter element 11 in this solution embodies a gradient filtration effect from coarse to fine. The pretreatment layer and coarse particle layer at the front end aim for high dirt holding capacity, sacrificing precision to protect the back end. The fine particle layer and fine filter layer at the back end aim for high filtration precision, focusing on completing the high-quality filtration task under the protection of the front end. This four-layer structure makes the filtration efficiency higher, and the impurities can be captured in layers, ensuring the stability of the water quality after circulating water filtration.

[0028] Specifically, in cleaning the baijiu fermentation workshop: Since the workshop needs to be cleaned multiple times daily, and the quality, flavor stability, and yield of the baijiu must be considered, it is crucial to ensure that the microbial environment remains intact after cleaning. This necessitates the use of a physical filtration structure to achieve the technical effect of not altering the chemical properties within the workshop and not killing microorganisms, thereby guaranteeing the flavor stability of each fermentation cycle. When applying the device in this solution to the cleaning of the baijiu fermentation workshop, the circulating filtration structure allows the daily cleaning water to be filtered and reused after being filtered by filter component 1, effectively saving water and improving economic efficiency. Furthermore, thanks to the physical filtration mechanism of filter component 1, the microbial environment in the repeatedly used circulating water after filtration by filter component 1 remains intact, resulting in a more stable baijiu output.

[0029] Specifically, the circulating water used in the liquor fermentation workshop is changed once a day.

[0030] In some embodiments, see Figure 1 and Figure 2 The water-using device 4 includes a second pipe 41 and a switch valve 42. The outlet end of the filter assembly 1 is connected to the inlet end of the second pipe 41, and the outlet end of the second pipe 41 is connected to the switch valve 42. In this way, the water-using device 4 can be used to discharge the circulating water filtered by the filter assembly 1. Specifically, the second pipe 41 can be easily moved to the location that needs cleaning, and the switch valve 42 can be used to control the opening and closing of the circulating water discharge.

[0031] Specifically, this solution only indicates that the second pipe 41 is connected to the switch valve 42, which does not mean that the other pipes are not connected to the switch valve 42. The use of the switch valve 42 can be flexibly configured.

[0032] In some embodiments, see Figure 2 The cleaning device also includes a water storage device 5. The outlet of the filter assembly 1 is connected to the inlet of the second pipe 41 via the water storage device 5. The water storage device 5 includes a third pipe 51 and a second water tank 52. The inlet of the third pipe 51 is connected to the outlet of the filter assembly 1, and the outlet of the third pipe 51 is connected to the inlet of the second water tank 52. The outlet of the second water tank 52 is connected to the inlet of the second pipe 41. In this way, the water storage device 5 is set between the filter assembly 1 and the water-using device 4. The second water tank 52 of the water storage device 5 stores the circulating water filtered by the filter assembly 1, ensuring a sufficient water supply when the water-using device 4 is flushed.

[0033] Specifically, the cleaning device in this solution has the following two connection methods: Example 1, see Figure 1The filter assembly 1 is directly connected to the water-using equipment 4. It filters the circulating water in the first water tank 2 while draining and rinsing the water through the water-using equipment 4. Example 2, see Figure 2 The filter assembly 1, the water storage device 5, and the water-using device 4 are connected in sequence. The water storage device 5 holds the circulating water filtered by the filter assembly 1. During flushing, the circulating water in the water storage device 5 is discharged through the water-using device 4. This structure has a higher stability of the circulating water output during flushing and is conducive to providing circulating water with higher water pressure during flushing.

[0034] The only difference between the two embodiments is whether or not a water storage device 5 is used. For other structures not mentioned, such as the first water tank 2 and the first pipe 3, the connection methods in both embodiments are the same.

[0035] In some embodiments, the top of the first water tank 2 and the water inlet of the second water tank 52 are both located at the top, and the water outlets are both located at the bottom; wherein, the top of the first water tank 2 and the top of the second water tank 52 are both provided with hinged covers. In this way, the hinged covers on the top of the first water tank 2 and the top of the second water tank 52 reduce the impact of the external environment on the circulating water in the two water tanks.

[0036] Specifically, since the first water tank 2 contains the circulating water before filtration, the cover can be connected only to the top of the second water tank 52 to avoid the influence of the external environment on the circulating water after filtration.

[0037] In some embodiments, a filter element is provided inside the first water tank 2, and the filter element is disposed between the water inlet and the water outlet of the first water tank 2. In this way, since the first water tank 2 is used to contain the circulating water before filtration, the filter element inside the first water tank 2 can play a preliminary filtration role for the circulating water, thereby reducing the filtration pressure of the filter assembly 1, reducing the accumulation of impurities in the filter assembly 1, and thus extending the continuous service life of the filter assembly 1.

[0038] Specifically, the filter element includes a connecting frame and filter cotton. The connecting frame is detachably installed circumferentially inside the first water tank 2, and the middle part of the connecting frame has a mesh-like double-layer structure. The filter cotton is detachably filled inside the double-layer structure of the connecting frame. In this way, the filter element is detachably connected to the first water tank 2 through the connecting frame, and large particles of impurities are blocked by the filter cotton. When a large amount of impurities accumulates on the filter cotton, the filter element can be removed for replacement or cleaning.

[0039] In some embodiments, the bottom of the cleaning device is equipped with rollers; the power unit includes an electrically connected water pump and a power supply. Thus, the rollers at the bottom of the cleaning device facilitate its movement, allowing it to follow the device to the location requiring cleaning during the cleaning of the liquor fermentation workshop; the cleaning device as a whole can be an integrated structure with a housing, and the rollers at the bottom of the housing facilitate the overall movement of the cleaning device.

[0040] A cleaning system for a fermentation workshop includes cleaning devices. The cleaning system also includes a water tap 6, through which tap water is added to a first water tank 2. The water tap 6 is connected to a tap water pipe. For example, if the circulating water in the fermentation workshop needs to be changed daily, new clean water is used to clean the fermentation workshop each day. Specifically, during the first cleaning shift of the day, new tap water is added to the first water tank 2, and subsequent cleaning processes of the day use circulating water formed after filtering this portion of tap water to clean the fermentation workshop.

[0041] For details, see Figure 1 and Figure 2 The cleaning device also includes a fourth pipe 7, through which the outlet of the first water tank 2 is connected to the inlet of the filter assembly 1.

[0042] In the circulating water flow structure of this scheme, the driving force for the circulating water flow comes from the power component. There are no specific restrictions on the relative position of the power component with the first water tank 2, the second water tank 52, the filter component 1, or the pipes, etc., as long as the position is reasonable and can drive the flow of circulating water. The position of the power component is set by conventional technical means, which will not be elaborated in this scheme.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
