Description

Technical Field

[0001] This utility model relates to a sampling and drainage device for corrosive high-temperature wastewater produced in wet electronic chemical production. Background Technology

[0002] In the production of wet electronic chemicals, evaporator pipelines need to be sampled regularly to monitor fluid parameters (such as solid-liquid ratio), and qualified fluids are safely discharged through a draining operation.

[0003] In existing technologies, this process is usually carried out in an open environment, where operators are in direct contact with high-temperature, potentially corrosive fluids, posing significant safety hazards. As the core equipment for high-concentration brine treatment, the discharge stage of the MVR evaporation system is a technical challenge, especially in the production of electronic chemicals, where the fluid temperature is relatively high and it is corrosive, requiring extremely high operational safety. In view of this, this utility model proposes a sampling and discharge device for corrosive high-temperature wastewater from wet electronic chemical production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a sampling and drainage device for corrosive high-temperature wastewater from the production of wet electronic chemicals, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sampling and drainage device for corrosive high-temperature wastewater from the production of wet electronic chemicals includes a cabinet, wherein two sets of connecting pipes are installed inside the cabinet. The connecting pipe is equipped with a feeding pipe and a feeding valve. The connecting pipe is also equipped with a sampling port and a discharge port. The sampling port is located inside the cabinet, and the discharge port is located outside the cabinet. A sampling valve for controlling sampling is installed at the sampling port, and a discharge valve for controlling discharge is installed at the discharge port.

[0006] As an improvement to the above technical solution, a hopper is provided at the bottom of the cabinet, a guide pipe is provided in the hopper, and a guide valve is provided on the guide pipe; A storage box is provided at the bottom of the guide pipe.

[0007] As an improvement to the above technical solution, the cabinet is provided with two sets of rectangular windows, which are respectively matched with the positions of the feed valve and the sampling valve. The rectangular window is equipped with an operating door connected by a hinge.

[0008] As an improvement to the above technical solution, a U-shaped shell is provided inside the cabinet, and the U-shaped shell is located at a set of rectangular windows at the bottom. The connecting pipe is installed through the U-shaped housing, and the sampling valve is installed inside the U-shaped housing.

[0009] As an improvement to the above technical solution, the cabinet is provided with a first grid plate and a second grid plate. The first grid plate is disposed between two sets of rectangular windows, and the second grid plate is disposed on the hopper.

[0010] As an improvement to the above technical solution, a flow channel is provided between the U-shaped shell and the side wall of the cabinet, through which the liquid on the first grid plate enters the hopper.

[0011] As an improvement to the above technical solution, the bottom of the cabinet is provided with multiple sets of support legs, which are fixedly connected to the cabinet.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By placing the sampling port of high-temperature wastewater completely inside the cabinet and using the cabinet's enclosed structure, the risk of operators coming into direct contact with high-temperature, potentially corrosive, or hazardous fluids is effectively isolated, significantly reducing safety hazards such as burns and chemical splashes during sampling and providing reliable protection for workers. The device is directly integrated into the evaporator pipeline and connected via the feed pipe. It can complete two key operations, sampling and analysis and compliance discharge, at a single station. During sampling, the feed valve and sampling valve are opened, and the fluid flows out from the sampling port inside the cavity for testing. Once the test confirms that the fluid meets the discharge standards, the sampling valve only needs to be closed and the discharge valve opened at the same time. The compliant fluid is then safely discharged from the system through the discharge port located outside the cabinet. This design eliminates the cumbersome steps of switching connections or transferring samples multiple times in the traditional method. Based on real-time sampling and detection results, the same fluid flow path is switched by opening and closing the corresponding valves to achieve efficient closed-loop control of "detection-judgment-execution discharge". Once the standard is confirmed, without interrupting production or disassembling the device, the qualified fluid can be directly guided to the designated discharge pipeline through the discharge port, which greatly shortens the processing cycle and improves the production line operating efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: like Figure 1-5 As shown, this embodiment proposes a sampling and drainage device for corrosive high-temperature wastewater from the production of wet electronic chemicals, including a cabinet 10, wherein two sets of connecting pipes 30 are provided inside the cabinet 10. The connecting pipe 30 is provided with a feeding pipe 33, and the feeding pipe 33 is provided with a feeding valve 34. The connecting pipe 30 is provided with a sampling port 35 and a discharge port 31. The sampling port 35 is located in the inner cavity of the cabinet 10, and the discharge port 31 is located on the outside of the cabinet 10. A sampling valve 36 for controlling sampling is provided at the sampling port 35, and a discharge valve 32 for controlling discharge is provided at the discharge port 31.

[0017] In this embodiment, before sampling and treating the high-temperature wastewater in the evaporator during the production of wet electronic chemicals, the cabinet 10 is placed in the evaporator pipeline of the wet electronic chemical production line, and the feed pipe 33 is connected to the evaporator pipeline of the wet electronic chemical production line. Then, by opening the feed valve 34 and the sampling valve 36, the fluid in the production line flows out from the sampling port 35. The fluid flowing out from the sampling port 35 is evaluated according to the production process requirements, and the sampling valve 36 is closed at the same time. When the evaluation meets the emission standards, the discharge valve 32 is opened, so that the fluid that meets the emission standards flows out through the discharge port 31. After the discharge is completed, the feed valve 34 and the discharge valve 32 are closed. Of course, a flow pipeline for the fluid that meets the emission standards is provided at the discharge port 31. By placing the sampling port 35 of the high-temperature wastewater completely inside the inner cavity of the cabinet 10, and in conjunction with the closed structure of the cabinet 10, the risk of operators coming into direct contact with high-temperature, potentially corrosive or dangerous fluids is effectively isolated, significantly reducing safety hazards such as burns and chemical splashes during the sampling process, and providing reliable protection for operators. The device is directly integrated into the evaporator pipeline and connected via the feed pipe 33. It can complete two key operations, sampling analysis and emission compliance, at a single station. During sampling, the feed valve 34 and the sampling valve 36 are opened, and the fluid flows out from the sampling port 35 inside the cavity for testing. Once the test confirms that the fluid meets the emission standards, the sampling valve 36 is closed and the discharge valve 32 is opened. The compliant fluid is then safely discharged from the system through the discharge port 31 located outside the cabinet 10. This design eliminates the cumbersome steps of switching connections or transferring samples multiple times in the traditional method. Based on real-time sampling and detection results, the same fluid flow path is switched, that is, the corresponding valve is opened and closed, to achieve efficient closed-loop control of "detection-judgment-execution discharge". Once the standard is confirmed, without interrupting production or disassembling the device, the qualified fluid can be directly guided to the designated discharge pipeline through the discharge port 31, which greatly shortens the processing cycle and improves the production line operating efficiency.

[0018] Specifically, a hopper 14 is provided at the bottom of the cabinet 10, a guide pipe 15 is provided on the hopper 14, and a guide valve 16 is provided on the guide pipe 15; A storage box 20 is provided at the bottom end of the guide pipe 15.

[0019] In this embodiment, the hopper 14 set at the bottom of the cabinet 10 serves as a receiving structure to effectively collect the fluid dripping during the sampling operation. Through the guide pipe 15 connected to it and the storage box 20 configured at the bottom, a flow channel is constructed from the inside of the cabinet 10 to the external container, ensuring that the fluid is directed to the dedicated storage box 20 for temporary storage. This facilitates the detection and evaluation of the fluid and also prevents its disorderly diffusion into the fluid being tested.

[0020] Specifically, the cabinet 10 has two sets of rectangular windows 13, and the two sets of rectangular windows 13 are respectively matched with the positions of the feed valve 34 and the sampling valve 36; An operating door 12, connected by a hinge, is provided at the rectangular window 13.

[0021] In this embodiment, the two sets of rectangular windows 13 are precisely matched with the positions of the feed valve 34 and the sampling valve 36, respectively, providing directional access channels for operators; By opening the operating door 12 connected by a hinge on the corresponding rectangular window 13, the valve can be directly accessed and controlled without disassembling the overall structure of the cabinet 10, which significantly simplifies the valve opening and closing, status inspection or emergency maintenance process and improves the ease of operation.

[0022] Specifically, the cabinet 10 is provided with a U-shaped shell 50, which is located at a set of rectangular windows 13 at the bottom. The connecting pipe 30 is installed through the U-shaped housing 50, and the sampling valve 36 is installed inside the U-shaped housing 50.

[0023] In this embodiment, the U-shaped housing 50 is arranged in an enclosing manner at the position corresponding to a set of rectangular windows 13 at the bottom, forming an isolated operating space independent of the main cavity of the cabinet 10. The connecting pipe 30 that runs through the U-shaped housing 50 and the sampling valve 36 placed inside it are completely covered in this cavity. When the operator opens the sampling valve 36, he can directly reach into the U-shaped housing 50 to operate by opening the operating door 12, which significantly enhances the physical sealing of the core area of ​​the sampling operation and effectively isolates the impact of fluid splashing on the operator during sampling.

[0024] Specifically, the cabinet 10 is provided with a first grid plate 40 and a second grid plate 60. The first grid plate 40 is disposed between two sets of rectangular windows 13, and the second grid plate 60 is disposed on the hopper 14.

[0025] In this embodiment, the first grid plate 40 serves as a rigid load-bearing platform, providing a stable and breathable working surface for operators to control valves through the rectangular window 13; its grid structure allows for line of sight and air circulation, while effectively preventing tools, parts, etc. from accidentally falling into the hopper 14 below or the U-shaped housing 50, ensuring operational safety and component integrity. The second grid plate 60 covers the inlet of the hopper 14. Its grid structure allows residual liquid or accidental dripping liquid to pass through and fall into the hopper 14 efficiently, while blocking solid debris from entering the collection system. The grid gaps facilitate rapid liquid flow, reduce liquid residue on the plate, accelerate the drying of the inside of the cabinet 10, and reduce the risk of corrosion and cross-contamination.

[0026] Specifically, a flow channel 70 is provided between the U-shaped shell 50 and the side wall of the cabinet 10, through which liquid on the first grid plate 40 enters the hopper 14.

[0027] In this embodiment, when the first grid plate 40 located on the upper layer receives dripping liquid (such as valve operation residue or cleaning wastewater), it falls naturally under the action of gravity. The flow channel 70 serves as a physical channel to avoid the U-shaped housing 50, ensuring that the liquid passes through the space between the first grid plate 40 and the U-shaped housing 50 without obstruction and flows directly into the hopper 14 at the bottom, thereby improving the efficiency and reliability of liquid collection.

[0028] Specifically, the bottom of the cabinet 10 is provided with multiple sets of support legs 11, and the multiple sets of support legs 11 are fixedly connected to the cabinet 10.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
