Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field more particularly is a kind of silicon wafer slice cleaning overflow wastewater recycling device. BACKGROUND

[0002] Wastewater refers to the water discharged in the process of residents' activities and runoff rainwater. It includes domestic wastewater, industrial wastewater and initial rain runoff into drainage pipe and other useless water. Generally, it refers to water that cannot be recycled or treated after primary pollution, and the difficulty of pure treatment does not reach a certain standard.

[0003] In the process of silicon wafer slice cleaning, the overflow wastewater recycling device plays a crucial role. The device uses a series of advanced technical means to convert wastewater into reusable resources. Wastewater is first introduced into the device and naturally stratifies in the sedimentation tank by gravity settling. The heavier particles gradually deposit at the bottom, while the lighter clean water slowly floats up. This step effectively removes most of the suspended solids in the wastewater. Next, the device uses a filter cartridge filtration system. The filter cartridge further intercepts small particles, oil and other impurities in the water with its small pore size, significantly improving water quality. To deeply purify water quality, the device is also equipped with an advanced membrane treatment unit. Through the selective permeability of ultrafiltration or reverse osmosis membranes, small molecules, bacteria, viruses and other impurities in the water are effectively removed, and the water quality meets the recycling standard. The entire recycling device not only realizes the recycling of water resources, reduces production costs, but also provides strong support for the green development of the semiconductor industry. The use of this technology fully embodies the dual advantages of environmental protection and economic benefits.

[0004] Although the existing device has many beneficial effects, it still has the following problems: during the wastewater recycling process, the filter screen will accumulate some silicon wafer fragments over a long period of use. Too many fragments can cause the filter screen to clog, reducing its interception capacity and affecting the effectiveness of wastewater treatment. In addition, the filter cartridge replacement process of the filtering device is complicated, which delays the overall device efficiency. Therefore, improvement is needed. In view of this, we propose a silicon wafer slice cleaning overflow wastewater recycling device. Utility model content

[0047] In some embodiments, the filter material 372 is selected as a high-quality polypropylene (PP) melt-blown filter cotton as the core material. This material has shown extraordinary performance in wastewater treatment due to its outstanding filtration efficiency, excellent chemical stability, and corrosion resistance. It can efficiently capture and remove suspended particles, dust, and some dissolved organic matter in water, ensuring preliminary purification of water quality. The fine and uniform fiber structure of PP melt-blown filter cotton not only improves filtration efficiency but also ensures low resistance when water flows through, thereby reducing energy consumption. In addition, this material has good regenerative properties and can be reused after simple cleaning and regeneration, greatly reducing operating costs. Filter material 374 is selected as an advanced reverse osmosis membrane. This membrane is made of high-tech synthetic materials and has extremely high selective permeability, effectively preventing dissolved salts, organic matter, bacteria, and viruses in water from passing through, while only allowing water molecules to pass through in a permeable manner. This characteristic of reverse osmosis membrane makes it have a wide application prospect in wastewater deep treatment and reuse.

The filter core 370 of the filter assembly 300 adopts a multi-layer filtration structure. This structure can more effectively remove small particles, oil, and other harmful substances in wastewater, improving the water quality standard of wastewater reuse. At the same time, the multi-layer filtration structure can also be combined and adjusted according to actual needs to adapt to different wastewater treatment needs.

The content protected by the present application does not involve improvements to the internal structure and method.

[0049] The device or equipment model involved in this paper is as follows:

[0050] Push-pull motor 250: GM80.

[0051] Working principle:

[0052] When the device works, the wafer slices are placed in the cleaning machine 120 of the cleaning assembly 100, and the cleaning liquid is fully mixed with the wafer slices through the rotation of the stirring piece 130, so that the wafer slices are cleaned. The waste water generated in the cleaning process automatically flows into the waste water treatment assembly 200 through the design of the cleaning machine 120. The waste water enters the inside of the shell 210 of the waste water treatment assembly 200, is first subjected to preliminary filtration through the filter screen 270, and removes larger suspended solids and impurities. In the process of preliminary filtration of the waste water, the wafer debris intercepted will accumulate on the top of the filter screen 270, the push-pull block 230 and the push-pull rod 240 are pushed by the push-pull motor 250, so that the support rod 231, the fixed plate 232 and the rubber strip 233 connected with the bottom of the push-pull block 230 move in parallel, the rubber strip 233 is used to clean the debris on the filter screen 270, so that the debris is swept into the waste box 290 on the side of the shell 210, and the debris is conveniently cleaned regularly. Subsequently, the waste water falls into the sedimentation tank at the bottom under the guidance of the drainage block 282 and is subjected to sedimentation. The clamping strip 281 is used to facilitate the placement of the filter screen 270, and these structures help the waste water to be uniformly distributed and improve the treatment efficiency. When the water level of the sedimentation tank is higher than the hole in the middle of the partition plate 280, the water flows into the water storage area. The waste water subjected to preliminary treatment flows into the filter box 310 of the filtration assembly 300 through the water outlet 212 of the water storage area of the shell 210. The waste water enters the water inlet 340 and is subjected to deep filtration through a plurality of filter cartridges 370 in the filter support 350. The filter cartridge 370 is composed of a plurality of filter materials, including the filter material 372 and the filter material 374, and can remove small particles, grease and other harmful substances in the waste water. The waste water subjected to deep filtration flows out of the water outlet 330 of the filter box 310, and the water quality has reached the reuse standard at this time, so that the water can be reused for the cleaning of the wafer slices or other process requirements. At the same time, the filter screen 270 and the filter cartridge 370 can be replaced or cleaned according to the needs, so as to ensure the waste water treatment effect. In addition, the filter support 350 can be taken out of the filter box 310 through the design of the lifting block 360, so as to replace the filter cartridge 370. The working process of the wafer slice cleaning overflow waste water reuse device realizes efficient treatment and reuse of the waste water, saves water resources, and reduces environmental pollution.

[0053] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and do not limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
