Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and in particular to a water-saving system for a water tank and a cleaning machine. Background Technology

[0002] In the photovoltaic manufacturing process, silicon wafers need to be cleaned with various chemicals and pure water in a wet cleaning tank. The chemicals and pure water are placed in different cleaning tanks, which mainly include alkaline cleaning tanks, acid cleaning tanks, and water tanks. Generally, alkaline cleaning tanks and acid cleaning tanks are followed by water tanks, where pure water is used to remove residual chemicals from the surface of the silicon wafers after alkaline or acid cleaning.

[0003] Cleaning machines typically contain multiple water tanks, each with a volume of approximately 700L. Furthermore, to maintain the purity of the water and to prevent overflow of water from the tanks when the carriers carrying silicon wafers enter, the tanks constantly overflow with old water while simultaneously receiving new water, resulting in extremely high water consumption and a waste of water resources. Utility Model Content

[0004] The purpose of this invention is to provide a water-saving system and cleaning machine for a sink, so as to reduce the water consumption of the sink and achieve water conservation.

[0005] To achieve this objective, the technical solution adopted by this utility model is as follows:

[0009] A water supply pipe, one end of which is connected to the outer tank and the other end of which is connected to the inner tank of other water tanks, is equipped with a water pump and a water supply valve. The water supply valve is used to open and close the water supply pipe, and the water pump is configured to transport water from the outer tank to the inner tank of other water tanks through the open water supply pipe.

[0010] A drain pipe, one end of which is connected to the inner tank, is equipped with a drain valve for opening and closing the drain pipe.

[0011] As an optional water-saving system for the water tank, a level gauge is installed inside the outer tank to detect the water level in the outer tank.

[0012] As an optional solution for the water-saving system of the water tank, the level gauge is communicatively connected to the water pump;

[0013] The water tank's water-saving system has a normal mode and a water-saving mode. In the normal mode, the water pump remains off.

[0014] As an optional water-saving system for the water tank, the height of the top of the outer tank is greater than the height of the top of the inner tank.

[0015] As an optional solution for the water-saving system of the sink, the water-saving system of the sink also includes a drain pipe, one end of which is connected to the bottom end of the inner tank, and a drain valve is installed on the drain pipe for opening and closing the drain pipe.

[0016] As an optional solution for the water-saving system of the sink, the water-saving system of the sink also includes a main pipe, one end of which is connected to the bottom end of the outer tank, and the other end of which can be connected to one end of the water supply pipe and the drain pipe respectively.

[0020] The cleaning machine includes a water-saving system for the aforementioned water tank.

[0021] The beneficial effects of this utility model are as follows:

[0022] The water-saving system for the water tank proposed in this utility model involves an inlet pipe supplying water to the inner tank, where water overflows through an open end to the outer tank, allowing the outer tank to function as a storage tank and thus storing water. When other water tanks do not require water replenishment, water in the outer tank is discharged through an open drain pipe. When other water tanks require water replenishment, a water replenishment valve and a water pump are opened.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] This embodiment proposes a cleaning machine, which is a wet-type tank cleaning machine used in photovoltaic production equipment. The cleaning machine contains various cleaning tanks, mainly including alkaline washing tanks, acid washing tanks, and water tanks. Both the alkaline washing and acid washing tanks are followed by water tanks, where pure water is used to remove residual chemicals from the silicon wafer surface after alkaline or acid washing.

[0033] Cleaning machines typically contain multiple water tanks, each with a volume of approximately 700L. Furthermore, to maintain the purity of the water and to prevent overflow of water from the tanks when the carriers carrying silicon wafers enter, the tanks constantly overflow with old water while simultaneously receiving new water, resulting in extremely high water consumption and a waste of water resources.

[0034] To solve the above problems, such as Figure 1As shown, this embodiment also proposes a water-saving system for a water tank. The water-saving system includes a water tank, an inlet pipe 3, a water supply pipe 4, and a drain pipe 7. The water tank includes an inner tank 1 and an outer tank 2, with the inner tank 1 housed inside the outer tank 2. Both the inner tank 1 and the outer tank 2 have open tops. The inlet pipe 3 is configured to supply water to the inner tank 1. One end of the water supply pipe 4 is connected to the outer tank 2, and the other end is connected to the inner tank 1 of other water tanks. The water supply pipe 4 is equipped with a water pump 5 and a water supply valve 6. The water supply valve 6 is used to open and close the water supply pipe 4. The water pump 5 is configured to transport water from the outer tank 2 to the inner tank 1 of other water tanks through the open water supply pipe 4. One end of the drain pipe 7 is connected to the inner tank 1, and the drain pipe 7 is equipped with a drain valve 8, which is used to open and close the drain pipe 7. Water is supplied to the inner tank 1 through the inlet pipe 3, and the water in the inner tank 1 overflows to the outer tank 2 through the open end, so that the outer tank 2 acts as a liquid storage tank, achieving water storage. When the inner tank 1 of other water tanks does not require water replenishment, the water in the storage tank can be discharged through the open drain pipe 7. When the inner tank 1 of other water tanks requires water replenishment, the water replenishment valve 6 and the water pump 5 are opened. Under the action of the water pump 5, the water in the outer tank 2 is transported to the inner tank 1 of other water tanks through the open water replenishment pipe 4, which improves the utilization rate of water in the outer tank 2, reduces the water consumption of the water tank, reduces the waste of water resources, and achieves water conservation.

[0035] It should be noted that the water-saving system of the sink has a normal mode and a water-saving mode. Since there are multiple water tanks inside the cleaning machine, when the previous water tank needs to be replenished, the water tank located behind it switches from normal mode to water-saving mode, and replenishes the water in the outer tank 2 into the previous water tank.

[0036] In normal mode, the water pump 5 of the water tank's water-saving system remains off, and the inlet pipe 3 supplies water to the inner tank 1. The water in the inner tank 1 overflows into the outer tank 2 through the open end at the top. When the water level in the outer tank 2 reaches a certain height, the drain valve 8 is opened, allowing the water in the outer tank 2 to be drained through the drain pipe 7, preventing overflow from the outer tank 2. When switching to water-saving mode, the drain valve 8 remains closed to prevent water from the outer tank 2 from flowing into the drain pipe 7.

[0037] like Figure 1 As shown, a level gauge 9 is installed inside the outer tank 2, and the level gauge 9 is used to detect the water level in the outer tank 2. The level gauge 9 can accurately measure the water level height in the outer tank 2. The level gauge 9 is communicatively connected to the water pump 5. Specifically, the level gauge 9 is electrically or signal-connected to the control module, and the control module is electrically or signal-connected to the water pump 5, so that the measured value of the level gauge 9 is transmitted to the control module of the cleaning machine, and the control module controls the opening and closing of the water pump 5. Since the control module is existing technology, its structure and operation will not be described in detail.

[0038] It should be noted that the liquid level in outer tank 2 has a minimum value (which can be flexibly set as needed). In normal mode, water pump 5 remains off, and there is no need to replenish water to other tanks. In water-saving mode, water pump 5 turns on when the level gauge 9 detects a value greater than the minimum value. Water pump 5 turns off when the level gauge 9 detects a value less than the minimum value. Water pump 5 can only be turned on when other tanks need to be replenished, and when the level gauge 9 detects a value greater than the minimum value, to ensure that there is sufficient water in outer tank 2. When the liquid level in outer tank 2 drops to the minimum value, water pump 5 turns off, ending the replenishment process, to ensure that a small amount of water remains in outer tank 2 and to prevent water pump 5 from running dry and being damaged.

[0039] like Figure 1 As shown, the height of the top of the outer tank 2 is greater than the height of the top of the inner tank 1. This design ensures that the sidewall height of the outer tank 2 is higher than that of the inner tank 1, preventing water from overflowing from the inner tank 1 and splashing onto the outside of the outer tank 2, thus maintaining the cleanliness of the surrounding environment and reducing water loss. Simultaneously, the higher sidewall height of the outer tank 2 increases its water storage capacity.

[0040] like Figure 1 As shown, the water-saving system of the water tank also includes a drain pipe 10, one end of which is connected to the bottom end of the inner tank 1. A drain valve 11 is installed on the drain pipe 10, which is used to open and close the drain pipe 10. When the drain valve 11 is opened, the water in the inner tank 1 is discharged through the drain pipe 10 to quickly empty the inner tank 1, facilitating maintenance or cleaning of the inner tank 1.

[0041] It should be noted that the above-mentioned water supply valve 6, drain valve 8 and relief valve 11 are all manual valves, which are opened and closed manually by the operator. They have a simple structure, are easy to operate, ensure the reliability of the opening and closing of each valve body, and avoid electrical failures.

[0042] like Figure 1 As shown, the water-saving system of the sink also includes a main pipe 12. One end of the main pipe 12 is connected to the bottom end of the outer tank 2, and the other end of the main pipe 12 can be connected to one end of the water supply pipe 4 and the drain pipe 7, respectively. The water supply pipe 4 and the drain pipe 7 share the same main pipe 12 connected to the outer tank 2, which simplifies the piping structure of the water-saving system of the sink and optimizes the piping space.

[0043] In an optional embodiment, the water-saving system of the sink also includes a backup pipe, with the main pipe 12 and the backup pipe having opposite opening and closing states. One end of the backup pipe is connected to the bottom end of the inner tank 1, and the other end of the backup pipe can be connected to one end of the water supply pipe 4 and the drain pipe 7, respectively. When the main pipe 12 is open, the backup pipe remains closed; when the main pipe 12 is closed, the backup pipe remains open. By setting up a backup pipe, water can be supplied to the water supply pipe 4 and the drain pipe 7 through the backup pipe when the main pipe 12 fails or requires maintenance, thereby improving the redundancy of the water-saving system of the sink.

[0044] In an optional embodiment, the main pipe 12 is equipped with a one-way valve, which is configured to allow water in the outer tank 2 to flow unidirectionally to the water supply pipe 4 or the drain pipe 7. By setting the one-way valve, the water in the main pipe 12 can flow unidirectionally, preventing water in the water supply pipe 4 (in case of accidents such as pump 5 failure) or the drain pipe 7 from flowing back into the outer tank 2.

[0045] like Figure 1 As shown, a filter 13 is installed on the drain pipe 7, located upstream of the water pump 5 along the water flow direction within the drain pipe 7. Since the tops of both the inner tank 1 and the outer tank 2 are open, dust and other particulate impurities may fall into them. By installing the filter 13 upstream of the water pump 5, impurities that may be present in the water entering the water pump 5 are filtered out, preventing impurities from entering the water pump 5 and thus protecting it. Since the filter 13 is existing technology, there are no specific limitations on its type; it only needs to be able to filter impurities from the water.

[0046] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
