[0024] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0025] As Figures 1 - 6As shown in the figure, the present utility model proposes a liquid recycling device in a first aspect, which is used for recycling solvents and cleaning water. The liquid recycling device includes a water storage tank 100, a water diversion hood 200, a water distribution mechanism 300 and two return pipes 400. A first partition 103 is provided in the water storage tank 100 to divide a part of the water storage tank 100 into a first chamber 101 and a second chamber 102. A first water inlet 104 and a second water inlet 105 are provided on the water storage tank 100. The first water inlet 104 is communicated with the first chamber 101, and the second water inlet 105 is communicated with the second chamber 102. Filter elements 106 for filtering impurities in the liquid are provided in both the first chamber 101 and the second chamber 102. A heating element 107 is also provided in the first chamber 101. The water diversion hood 200 is arranged above the water storage tank 100 to introduce solvents or cleaning water into the water storage tank 100. The water distribution mechanism 300 is movably installed on the water storage tank 100. Among them, the water distribution mechanism 300 moves and stays above the first water inlet 104 to divert the solvent in the water diversion hood 200 into the first chamber 101, and the water distribution mechanism 300 moves and stays above the second water inlet 105 to divert the cleaning water in the water diversion hood 200 into the second chamber 102. The two return pipes 400 are respectively communicated with the first chamber 101 and the second chamber 102 to be used for recycling the treated solvents and cleaning water.

[0026] Specifically, the liquid recycling device in this embodiment is used to receive the solvents and cleaning water after cleaning the steel mesh. Therefore, these solvents and cleaning water already have certain impurities when entering the liquid recycling device. Therefore, when reusing these solvents and cleaning water, they need to be processed. First, they are collected through the water storage tank 100. In order to prevent the solvents and cleaning water from being collected in the same chamber during the collection process, resulting in the mixing of the solvents and cleaning water and affecting the subsequent reuse effect, the water distribution mechanism 300 is used to separate and collect the solvents and cleaning water. The water storage tank 100 is also correspondingly divided into a first chamber 101 and a second chamber 102 by the first partition 103 for collecting solvents and cleaning water. It should be noted that the solvents and cleaning water do not enter the liquid recycling device together. In the previous step of cleaning the steel mesh, the steel mesh is first cleaned with solvents and then rinsed with cleaning water. The use of the solvents and cleaning water here has a sequential order. Therefore, the liquid recycling device also utilizes this sequential order when receiving and processing the solvents and cleaning water. The solvents and cleaning water are respectively collected into the first chamber 101 and the second chamber 102. The impurities in the solvents and cleaning water are filtered by the internal filter elements 106. A heating element 107 is additionally provided in the first chamber to heat the solvent to remove the compounds generated with the steel mesh, and the compounds are deeply filtered in combination with the filter elements to obtain relatively clean solvents and improve the utilization rate.

[0027] The filter element 106 separates impurities from the treated solvent and clean water, and transports the treated solvent and clean water to the equipment for cleaning the steel mesh through the reflux pipe 400, realizing the reuse of the solvent and clean water. Among them, the liquid recycling device further includes a water pump device, which is connected to the reflux pipe 400 to pump the treated solvent and clean water in an active manner.

[0028] Further, the water separation mechanism 300 includes a guide rail 301, a water separation tank 302, and a first driving member 303. The water separation tank 302 is slidably connected to the guide rail 301. One side of the water separation tank 302 facing the water diversion hood 200 is open to receive and divert the clean water and solvent. The first driving member 303 is installed on the guide rail 301 and is drivingly connected to the water separation tank 302 to drive the water separation tank 302 to move along the direction of the guide rail 301.

[0029] Further, the water separation tank 302 is provided with a second partition plate 304 for dividing the inside of the water separation tank 302 into two diversion grooves 3021, and the two diversion grooves 3021 are respectively used for diverting clean water and solvent.

[0030] Specifically, in order to reduce the mutual contamination between the solvent and the clean water, the water separation tank 302 is provided with a second partition plate 304 to divide into two diversion grooves 3021, which are respectively used for diverting the solvent and the clean water. When diverting the solvent, the water separation tank 302 not only needs to move above the first water inlet, but also needs to place one of the diversion grooves 3021 for diverting the solvent below the water diversion hood 200. The same applies to diverting the clean water.

[0031] Further, the liquid recycling device further includes an extension plate 201, which is slidably installed on the water diversion hood 200 to extend the water outlet path of the water diversion hood 200.

[0032] Specifically, since the water separation tank 302 only moves in the direction of the guide rail 301, the entire water separation tank 302 is under the water diversion hood 200. When the water diversion hood 200 diverts water into one of the diversion grooves 3021, although the second partition plate 304 can play a certain isolation role, it is inevitable that the liquid collides with the inner wall of the diversion groove 3021 and splashes into the other diversion groove 3021 or even other places. Therefore, a slidable extension plate 201 is adopted to lengthen the water diversion port on the water diversion hood 200, so that the water diversion port extends into the diversion groove 3021 and is lower than the second partition plate 304, effectively avoiding the above problems.

[0033] Further, the water diversion hood 200 is provided with a second driving member 202, and the second driving member 202 is drivingly connected to the extension plate 201 to drive the extension plate 201 to slide on the water diversion hood 200. Both the first driving member 303 and the second driving member 202 are cylinder structures.

[0034] Further, the liquid recycling device further includes two liquid level sensors 500 and two liquid level gauges 600. The two liquid level sensors 500 are respectively installed in the first chamber 101 and the second chamber 102 to monitor the liquid levels of the solvent and the cleaning water. The two liquid level gauges 600 are both installed on the water storage tank 100 and are respectively connected to the two liquid level sensors 500 to record and display the liquid level values of the solvent and the cleaning water in real time.

[0035] In a second aspect of the present invention, there is provided a device, which includes the liquid recycling device according to any one of the above solutions.

[0036] The above is a liquid recycling device or multiple embodiments provided in combination with specific contents, and it is not considered that the specific implementation of the present invention is only limited to these descriptions. Any method, structure, etc. that is similar or identical to the present invention, or any technical deduction or replacement made under the premise of the concept of the present invention, should be regarded as the protection scope of the present invention.
