Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor processing technology, specifically to a wastewater collection device for semiconductor processing. Background Technology
[0002] Semiconductor wastewater refers to wastewater, sewage, and waste liquid generated during the production process. It contains production materials, intermediate products, and finished products lost with the water, as well as pollutants generated during the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Semiconductor wastewater is generally filtered through wastewater filtration devices.
[0003] In semiconductor processing, wastewater collection devices are required. Chinese utility model patent CN215667379U discloses a wastewater collection device for semiconductor processing, including a collection tank. The collection tank comprises a collection trough, an inlet pipe, and a drain pipe. The inlet pipe is located at the top of the collection tank and extends through the collection tank into the collection trough. This utility model introduces semiconductor wastewater into the collection tank through the inlet pipe. First, the wastewater passes through a microfiltration membrane in a microfiltration layer to filter particles. Then, it passes through an activated carbon filter in an activated carbon filter layer to further remove odors and impurities, improving the filtration effect and removing corrosive substances. The wastewater then flows into a collection trough for collection. A reverse osmosis layer prevents water in the collection trough from back-permeating into the activated carbon filter layer. An electrolyzer is installed in the collection trough. The electrolyzer is activated to electrolyze the water in the collection trough to obtain electrolyzed water. The bottom of the collection trough slopes towards the drain pipe, allowing the water in the collection trough to drain quickly.
[0004] However, during the use of this utility model, the semiconductor wastewater contains a large amount of solid waste, which will cause blockage inside the device after a long period of use. At the same time, there is no corresponding disassembly and assembly structure, making it inconvenient to replace the internal filter structure, which affects the practicality and cannot meet the production needs. Therefore, a semiconductor processing wastewater collection device is proposed to solve the above-mentioned problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a wastewater collection device for semiconductor processing, which has the advantage of easy replacement of filter parts. It solves the problem that semiconductor wastewater contains a large amount of solid waste, which can cause blockages in the device after prolonged use. Furthermore, the lack of a corresponding disassembly and assembly structure makes it difficult to replace the internal filter structure, thus affecting its practicality and failing to meet production needs.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater collection device for semiconductor processing, comprising a wastewater collection tank and a partition fixedly connected inside the wastewater collection tank, wherein a purification and filtration structure extending into the top of the wastewater collection tank is provided.
[0007] The purification and filtration structure includes a mounting base that is slidably connected to the top of the wastewater collection tank and extends into it. An internal threaded sleeve is fixedly connected to the lower surface of the mounting base. A purification and filtration cylinder extending into the wastewater collection tank is connected to the internal thread of the internal threaded sleeve. Mounting blocks are fixedly connected to both the left and right sides of the mounting base. A fixing bolt extending into the wastewater collection tank is threadedly connected to the top of the mounting block.
[0008] Furthermore, a diverter is fixedly installed on the top of the mounting base, and a connecting pipe is fixedly installed between the diverter and the mounting base, the connecting pipe being connected to the interior of the purification filter cartridge.
[0009] Furthermore, a delivery pump is fixedly installed on the top of the wastewater collection tank, the output end of the delivery pump is fixedly connected to the top of the distributor, and the end of the delivery pump away from the distributor is fixedly connected to a connecting pipe extending into the interior of the wastewater collection tank.
[0010] Furthermore, a drain pipe extending into the wastewater collection tank is fixedly connected to one side of the wastewater collection tank, and a dosing pipe extending into the wastewater collection tank is fixedly connected to the top of the front of the wastewater collection tank.
[0011] Furthermore, the wastewater collection tank is slidably connected to a pre-filter, a secondary filter, and an activated carbon filter extending to its front, which are arranged sequentially from left to right.
[0012] Furthermore, the primary filter consists of an installation frame, a filter core, and an installation plate. The filter core is fixedly connected to the inside of the installation frame. Positioning strips extending into the wastewater collection tank are fixedly connected to the top and bottom of the installation frame. The installation frame is fixedly connected to one side of the installation plate, and a sealing strip is fixedly connected to the side of the installation plate near the installation frame.
[0013] Furthermore, a drain pipe extending into the bottom of one side of the wastewater collection tank is fixedly connected, and an inlet pipe is fixedly connected to the side of the wastewater collection tank near the drain pipe.
[0014] Compared with the prior art, the present invention provides a wastewater collection device for semiconductor processing, which has the following advantages:
[0015] 1. This semiconductor processing wastewater collection device, by setting a mounting base and an internal threaded sleeve, facilitates the installation of the purification filter cartridge inside the wastewater collection tank, and also facilitates the disassembly and assembly of the purification filter cartridge. Furthermore, by setting a mounting block and fixing bolts, it is easy to install the mounting base. At the same time, by setting a delivery pump and delivery pipeline, and by setting a diverter, the filtered wastewater can be delivered to the purification filter cartridge, thereby purifying and filtering the wastewater.
[0016] 2. This semiconductor processing wastewater collection device, by setting up a pre-filter, a secondary filter, and an activated carbon filter, can perform preliminary filtration of wastewater. Simultaneously, the inclusion of positioning strips and sealing strips facilitates the disassembly and assembly of the pre-filter, while also providing a sealing effect. This solves the problem that semiconductor wastewater contains a large amount of solid waste, which can cause blockages to the device's internal structure after prolonged use. Furthermore, the lack of a corresponding disassembly and assembly structure makes it difficult to replace the internal filter structure, affecting practicality and failing to meet production needs.
