Description

Technical Field

[0001] This utility model relates to a cleaning production line, and more particularly to a double-tank water washing system. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] A double-tank washing tank generally consists of two independent, adjacent washing tanks. Its purpose is to use the first washing tank to perform a rough wash on the workpiece to be cleaned, and then put it into the second washing tank for further cleaning to achieve a better cleaning effect.

[0004] In existing technologies, water changes in double-unit washing tanks are generally done manually by operators, which is inefficient and prone to side-tilting leaks and contamination of the processing site. Furthermore, some washing tanks use external water pumps to assist in draining the inner cavity after cleaning; however, impurities in the wastewater can easily clog the pumps, causing damage, and further impacting cleaning and maintenance efficiency.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a dual-tank water washing system that can connect to a transfer pump via a downstream intermediate water tank, thereby replacing manual labor, reducing clogging, and improving cleaning efficiency.

[0007] To achieve the above objectives, this utility model discloses a double-tank washing system, which includes:

[0008] A first water washing tank, the bottom of which has a first drain outlet;

[0009] The second water washing tank has a second drain outlet at the bottom and is arranged adjacent to the first water washing tank.

[0010] The main water supply pipeline includes a branch-connected first water supply pipeline, a second water supply pipeline, and a spray pipeline at its downstream end. The first water supply pipeline is connected to the inner cavity of the first water washing tank, the second water supply pipeline is connected to the inner cavity of the second water washing tank, and the spray pipeline is connected to the inner cavity of the second water washing tank.

[0011] The main drainage pipeline includes a first drainage pipeline and a second drainage pipeline connected by branches at its upstream end. The first drainage pipeline is connected to the first drain outlet of the first washing tank, and the second drainage pipeline is connected to the second drain outlet of the second washing tank.

[0012] An intermediate water tank, the upstream end of which is connected to the downstream end of the main drainage pipeline, and the downstream end of which is connected to a transfer water pump.

[0013] As a further description of the above technical solution, the first water supply pipeline is provided with a first water supply pneumatic valve and a first water supply manual valve connected in series, and the second water supply pipeline is provided with a second water supply pneumatic valve and a second water supply manual valve connected in series.

[0014] As a further description of the above technical solution, the spray pipeline is equipped with a spray pneumatic valve and a spray pipeline manual valve connected in series.

[0015] As a further description of the above technical solution, an auxiliary manual valve is provided on the spray pipeline in parallel with the spray pneumatic valve and the spray pipeline manual valve.

[0016] As a further description of the above technical solution, the first drainage pipeline is provided with a first drainage pneumatic valve and a first drainage manual valve connected in series, and the second drainage pipeline is provided with a second drainage pneumatic valve and a second drainage manual valve connected in series.

[0017] As a further description of the above technical solution, a manual pump valve is provided before and after the transfer pump.

[0018] As a further description of the above technical solution, a first level gauge and a first acid-base sensor are provided in the inner cavity of the first water washing tank, and a second level gauge and a second acid-base sensor are provided in the inner cavity of the second water washing tank.

[0019] As a further description of the above technical solution, a third level gauge is provided in the inner cavity of the intermediate water tank.

[0020] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0021] This utility model's dual-tank washing system connects to a transfer pump via a downstream intermediate water tank, replacing manual labor and reducing clogging, thus improving cleaning efficiency. Specifically, the bottoms of the adjacent first and second washing tanks are connected to the intermediate water tank via a main drain pipe. This allows the intermediate water tank to have a temporary water storage capacity during wastewater discharge. Wastewater first collects inside the intermediate water tank instead of being directly discharged through the transfer pump. Therefore, impurities in the wastewater can accumulate in the intermediate water tank, or impurities that tend to accumulate at the bottom of the first and second washing tanks will also settle in the intermediate water tank and then be transferred out by the transfer pump, preventing clogging. The intermediate water tank can be removed separately for cleaning or replacement.

[0034] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0035] Please see Figure 1 This embodiment provides a double-tank washing system, wherein the double-tank washing system includes:

[0036] The first water washing tank 1 has a first drain outlet 11 at the bottom;

[0037] The second water washing tank 2 has a second drain outlet 21 at the bottom and is arranged adjacent to the first water washing tank 1.

[0038] The main water supply pipeline 3 has a downstream end that includes a first water supply pipeline 31, a second water supply pipeline 32, and a spray pipeline 33 that are connected by branches. The first water supply pipeline 31 is connected to the inner cavity of the first water washing tank 1, the second water supply pipeline 32 is connected to the inner cavity of the second water washing tank 2, and the spray pipeline 33 is connected to the inner cavity of the second water washing tank 2.

[0039] The main drainage pipe 4 has an upstream end including a first drainage pipe 41 and a second drainage pipe 42 that are connected by branches. The first drainage pipe 41 is connected to the first drain outlet 11 of the first washing tank 1, and the second drainage pipe 42 is connected to the second drain outlet 21 of the second washing tank 2.

[0040] The intermediate water tank 5 is connected to the downstream end of the main drainage pipe 4 at its upstream end, and to the transfer water pump 6 at its downstream end.

[0041] With the above structure, during use, the operator only needs to place the workpiece to be cleaned in the inner cavity of the first water washing tank 1, transfer the preliminarily cleaned workpiece from the first water washing tank 1 to the inner cavity of the second water washing tank 2, and start the PLC control system to open the main water supply pipeline 3, so that the first water supply pipeline 31 supplies water to soak and clean the workpiece in the first water washing tank 1, and the second water supply pipeline 32 supplies water to soak and clean the workpiece in the second water washing tank 2. After the workpiece in the second water washing tank 2 has finished soaking and cleaning, during the process of removing the workpiece, the spray pipeline 33 is opened to further clean it while lifting the workpiece.

[0042] When it is necessary to discharge the sewage from the first washing tank 1 and the second washing tank 2, the sewage is directly discharged from the first drain outlet 11 and the second drain outlet 21 at the bottom, and then transferred to the intermediate water tank 5 through the main drainage pipeline 4. After a certain amount of sewage is collected in the central water tank 5, it is then connected to the downstream transfer pump 6 to start and guide the sewage to the sewage station.

[0043] In the above embodiments, the transfer pump 6 can be connected to the downstream intermediate water tank 5, which can replace manual labor and reduce clogging, thus improving cleaning efficiency. Specifically, the bottoms of the adjacent first washing tank 1 and second washing tank 2 are connected to the intermediate water tank 5 through the main drainage pipe 4, so that the intermediate water tank 5 has a certain temporary water storage capacity when discharging sewage. The sewage first collects inside the intermediate water tank 5 instead of being discharged directly through the transfer pump 6.

[0044] Therefore, impurities in the sewage can be deposited and accumulated at the intermediate water tank 5, or impurities that are prone to accumulate at the bottom of the first washing tank 1 and the second washing tank 2 will also be deposited in the intermediate water tank, and then transferred out by the transfer water pump 6 to avoid blockage. The intermediate water tank 5 can be removed separately for cleaning or replacement.

[0045] In this embodiment, the first washing tank 1 and the second washing tank 2 are set as regular rectangular tanks with similar volume and size. Specifically, the first washing tank 1 and the second washing tank 2 are arranged to lean against each other on the left and right. Therefore, in some cases, only the second washing tank 2 can be filled with water, and the water in the second washing tank 2 can overflow towards the first washing tank 1, so that the relatively clean water can re-enter the first washing tank 1 for cleaning and reuse, which saves water.

[0046] The first drain outlet 11 and the second drain outlet 21 are both located at the bottom center of their respective washing tanks, which helps to maximize drainage efficiency. Similarly, the first water supply pipe 31 and the second water supply pipe 32, which are branches of the main water supply pipe 3, are also located at the top near the center of their respective washing tanks, which allows the water level to rise quickly and prevents splashing out of the washing tanks too close to the edge.

[0047] In this embodiment, the intermediate water tank 5 is located near the downstream end of the main drainage pipe 4. The main drainage pipe 4 connects to the intermediate water tank 5 near its bottom, allowing impurities in the sewage to settle more easily after entering the intermediate water tank 5. The intermediate water tank 5 has sufficient capacity, forming a large intermediate transfer space before the transfer pump 6. In actual use, once the water level in the intermediate water tank 5 is high enough, impurities in the sewage can settle before the sewage is discharged to the transfer pump 6. Therefore, it effectively avoids a direct impact on the transfer pump 6 during drainage, preventing dirt from accumulating in the precision blades and other structures of the transfer pump 6 and damaging its operation.

[0048] like Figure 1 As shown, a first pneumatic water supply valve and a first manual water supply valve are connected in series on the first water supply pipeline 31, and a second pneumatic water supply valve and a second manual water supply valve are connected in series on the second water supply pipeline 31. Specifically, taking the first pneumatic water supply valve and the first manual water supply valve as examples, the first manual water supply valve is normally open, while the first pneumatic water supply valve is opened or closed according to water supply needs. The first manual water supply valve is closed when maintenance or replacement of the first pneumatic water supply valve is required. Similarly, taking the second pneumatic water supply valve and the second manual water supply valve as examples, the second manual water supply valve is normally open, while the second pneumatic water supply valve is opened or closed according to water supply needs. The second manual water supply valve is closed when maintenance or replacement of the second pneumatic water supply valve is required. The main function of the first water supply pipeline 31 and the second water supply pipeline 32 is to provide water before and during cleaning.

[0049] Furthermore, the spray pipe 33 is equipped with a spray pneumatic valve and a spray pipe manual valve connected in series. The spray water supply manual valve is normally open, while the spray water supply pneumatic valve is opened or closed according to water supply needs. The spray water supply manual valve is closed when maintenance or replacement of the spray water supply pneumatic valve is required. The spray pipe 33 is primarily used for further spray cleaning of workpieces after they have been soaked and cleaned in the second washing tank 2. Based on the above structure, the spray pipe 3 is equipped with an auxiliary manual valve connected in parallel with the spray pneumatic valve and the spray pipe manual valve. In the default cleaning operation, the spray pneumatic valve and the spray pipe manual valve are closed. The parallel auxiliary manual valve allows for easy opening and connection of the spray pipe 33 during the cleaning process, enabling the spray at its end to provide temporary auxiliary cleaning.

[0050] Furthermore, the first drainage pipe 41 is equipped with a first drainage pneumatic valve and a first drainage manual valve connected in series, and the second drainage pipe 42 is equipped with a second drainage pneumatic valve and a second drainage manual valve connected in series. Their functions and principles are the same as above, and the purpose is to facilitate the maintenance and replacement of the first drainage pneumatic valve and the second drainage pneumatic valve.

[0051] Furthermore, a manual pump valve is installed before and after the transfer pump 6, which allows the transfer pump 6 to release water after a certain amount of sewage has accumulated in the intermediate water tank 5. This provides greater controllability, avoids clogging of the transfer pump 6, and facilitates maintenance and replacement of the transfer pump 6.

[0052] Furthermore, a first level gauge 12 and a first acid-base sensor 13 are installed in the inner cavity of the first washing tank 1, and a second level gauge 22 and a second acid-base sensor 23 are installed in the inner cavity of the second washing tank 2. The first level gauge 12 is used to monitor the water level in the first washing tank 1, and the first acid-base sensor 13 is used to monitor the water quality in the first washing tank 1. The same configuration is used in the second washing tank 2.

[0053] Furthermore, the inner cavity of the intermediate water tank 5 is equipped with a third level gauge 51, which can monitor the water level in the intermediate water tank 5 when the transfer water pump 6 is turned off before and after, thus preventing overflow.

Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
