The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0025] Example 1: As Figures 1-4 The system includes a drainage chamber 100, a clamping plate 110 fixedly installed on the inner wall of the drainage chamber 100, a filter plate 120 inserted into the inner wall of the clamping plate 110, a filter element 130 detachably installed on the inner wall of the filter plate 120, a slope provided on the inner wall of the drainage chamber 100, and a drainage assembly fixedly installed on the outer wall of the bottom left side of the drainage chamber 100.

The output end of the end filter 240 is connected to the filtered water chamber 300 through a second conduit 310.
[0026] The specific application scenario of this embodiment is as follows: By setting up a drainage component, a first self-priming pump 200 is set up in the drainage component to accelerate the drainage of sewage in the drainage chamber 100 into multiple filters 240 when draining sewage. This allows the sewage after cooling the semiconductor cutting equipment to be filtered step by step through multiple filters 240, thereby meeting the standard for reuse and improving the water-saving effect of the equipment. By setting sand and gravel of different diameters as the material for filtering sewage, no consumables are generated. After the sand and gravel are used, they can be washed and reused without generating consumables, thus improving the practicality and economy of the equipment.
[0027] Example 2: As Figure 1 and Figure 4Support legs 140 are fixedly installed at the four corners of the bottom of the drainage chamber 100. The first self-priming pump 200 is fixedly installed on the bottom outer wall of the drainage chamber 100. The input end of the first self-priming pump 200 is fixedly connected to the bottom inner wall of the drainage chamber 100 through the drainage pipe 210. The inner wall of the filter 240 is filled with sand and gravel. The bottom inner wall of the filter 240 can be detachably installed with a filter screen. The filter screen is used to limit the sand and gravel. The diameter of the sand and gravel in the multiple filters 240 is distributed from large to small. The bottom outer wall of the drainage chamber 100 is fixedly installed with a support frame 230. The outer wall of the support frame 230 is welded to the arc frame 231. There are two arc frames 231 at the top and bottom. The top and bottom outer walls of the filter 240 are respectively engaged with the upper and lower arc frames 231.
[0028] The specific application scenario of this embodiment is as follows: by turning on the first self-priming pump 200, the first self-priming pump 200 delivers the wastewater filtered by the filter element 130 to the initial filter 240, where it is further filtered by the sand and gravel in the filter 240 to filter out large semiconductor cutting impurities. When the wastewater passes through several filters 240 in sequence, the sand and gravel of different coarseness are filtered in stages, so that the filtered wastewater can be reused, thereby saving water and ensuring that the semiconductor cutting equipment can continue to work even during short-term water outages.
[0029] Example 3: As Figure 4 and Figure 5 The top of the filter water tank 300 is fixedly installed on the top of the drain tank 100 by a support rod 320. A viewing window 330 is fixedly installed on the outer wall of the front end of the filter water tank 300. A second self-priming pump 340 is fixedly installed on the outer wall of the bottom end of the filter water tank 300. The input end of the second self-priming pump 340 is connected to the inner wall of the filter water tank 300. The output end of the second self-priming pump 340 is fixedly connected to the return water pipe 341. The output end of the return water pipe 341 provides supplementary spray cooling to the semiconductor cutting area through a nozzle.
[0030] The specific application scenario of this embodiment is as follows: the cleanliness of the filtered water in the filter water tank 300 is checked by viewing the window 330, and then the water in the filter water tank 300 is transported to the semiconductor cutting section for spraying by turning on the second self-priming pump 340 to cool and dissipate heat on the cutting wafer.
[0031] The working principle of this utility model is as follows: When used by those skilled in the art, the spray water used to cool the semiconductor cutting equipment is introduced into the drainage chamber 100. The sewage flows to the filter plate 120 under the action of gravity through the ramp. After being filtered by the filter element 130, the first self-priming pump 200 is turned on, so that the sewage filtered by the filter element 130 is transported to the initial filter 240. The sewage is further filtered by the sand and gravel in the filter 240, filtering out large semiconductor cutting impurities. When the sewage passes through several filters 240 in sequence, the sand and gravel of different coarseness are filtered in stages, so that the filtered sewage can be reused. The filtered water is transported to the filter water chamber 300. The cleanliness of the filtered water in the filter water chamber 300 is checked by viewing the window 330. Then, the second self-priming pump 340 is turned on to transport the water in the filter water chamber 300 to the semiconductor cutting part for spraying, cooling and heat dissipating the cutting blade.
