Description

Technical Field

[0001] This utility model relates to the field of ultrapure water detection technology, and in particular to a device for constructing an ultrapure water conductivity testing environment. Background Technology

[0002] Ultrapure water refers to water with a resistivity of 18 MΩ·cm (25℃). It has virtually all impurities removed except for hydrogen and oxygen atoms, including bacteria, viruses, organic matter, and metal ions, and does not contain minerals needed by the human body. Its preparation is typically achieved through techniques such as distillation, deionization, and reverse osmosis. It is widely used in semiconductor manufacturing, pharmaceuticals, and laboratory research. Common methods for testing ultrapure water include conductivity measurement and pH value detection.

[0003] When measuring the conductivity of ultrapure water, the probe of the ultrapure water testing device is fully immersed in the ultrapure water and left to stand for 30 to 60 seconds until the reading stabilizes. Multiple measurements are required to obtain the average value. When it is necessary to measure the deeper parts of the ultrapure water, manual operation poses risks. Furthermore, after the part above the probe is fully immersed in the pure water, the water temperature fluctuates locally due to the heat generated by the device itself. Ultrapure water conductivity is extremely sensitive to temperature, which affects the accuracy of conductivity measurement. In addition, the complete immersion of the device may introduce air bubbles or disturb the water, causing tiny air bubbles to adhere to the electrode surface, further affecting the measurement accuracy. Therefore, a device for constructing an ultrapure water conductivity testing environment is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a device for constructing an ultrapure water conductivity testing environment to address the aforementioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model solves the problem that manual operation poses risks when measuring deeper parts of ultrapure water, and that the accuracy of conductivity measurement is affected when the part above the detection head is completely immersed in ultrapure water.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An apparatus for constructing an ultrapure water conductivity testing environment, comprising:

[0008] A lifting device, wherein a lifting frame is installed on the lifting device, and side plates are fixedly connected to both sides of the front of the lifting frame, and two fixing plates are fixedly connected between the two side plates;

[0009] A waterproof cylinder is disposed between two fixed plates. A through hole is provided at the bottom end of the waterproof cylinder. An ultrapure water detection device is provided inside the waterproof cylinder. A cap is fixedly connected to the top end of the ultrapure water detection device.

[0011] In a preferred embodiment of the ultrapure water conductivity testing environment construction device provided by this utility model, a fixing ring is fixedly connected to the middle of the surface of the ultrapure water testing device, and a sealing ring is fixedly connected to the bottom end of the fixing ring.

[0012] In a preferred embodiment of the ultrapure water conductivity testing environment construction device provided by this utility model, the top of the outer wall of the waterproof cylinder is threaded, and the cap is threadedly connected to the waterproof cylinder.

[0013] In a preferred embodiment of the ultrapure water conductivity testing environment construction device provided by this utility model, the left and right moving parts include a fixing frame fixed to two side plates, and a spiral rod is provided on the top of the fixing frame.

[0014] In a preferred embodiment of the ultrapure water conductivity testing environment construction device provided by this utility model, protrusions are fixedly connected to both sides of the top of the fixed frame, and a driving part is installed on one of the protrusions.

[0015] In a preferred embodiment of the ultrapure water conductivity testing environment construction device provided by this utility model, one end of the spiral rod is rotatably connected to the protrusion, and the other end of the spiral rod is drively connected to the output shaft of the drive unit.

[0016] In a preferred embodiment of the ultrapure water conductivity testing environment construction device provided by this utility model, a transmission plate is provided on one side of the waterproof cylinder, and an installation rod is fixedly connected to the top of one side wall of the transmission plate, with the installation rod placed on one side of the screw rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a device for constructing an environment for testing the conductivity of ultrapure water. By incorporating a waterproof cylinder and a cap, it isolates the upper part of the ultrapure water testing device from the ultrapure water when the testing head is lowered into the ultrapure water using a lifting device. This prevents the heat from the device from being conducted to the ultrapure water and also prevents ultrapure water from entering the ultrapure water testing device, ensuring the accuracy of subsequent conductivity tests. Furthermore, the lifting device replaces manual adjustment of the ultrapure water testing device, avoiding errors from manual operation and ensuring the safety of the testing personnel. A fixing ring and a sealing ring ensure the airtightness of the through-hole.

[0021] This utility model provides a device for constructing an environment for testing the conductivity of ultrapure water. By incorporating left and right moving parts, it can control the drive unit to rotate the screw rod when the conductivity of ultrapure water is tested by an ultrapure water testing device. Through a fixed ball, the transmission plate passes through a slider, causing the waterproof cylinder to move left or right under the limiting and guiding effect of the sliding hole and the slider. This enables multi-point ultrapure water conductivity testing and expands the detection range of the ultrapure water testing device. Attached Figure Description

A through hole 6 is provided at the bottom of the waterproof cylinder 5, allowing the testing head to extend. The ultrapure water testing device 7 is installed inside the waterproof cylinder 5 to measure the conductivity of ultrapure water. A cap 8 is fixedly connected to the top of the ultrapure water testing device 7 to seal the top of the waterproof cylinder 5. Threads are distributed on the top of the outer wall of the waterproof cylinder 5, and the cap 8 is threadedly connected to the waterproof cylinder 5. A left-right movable part 9 is provided on the top of the waterproof cylinder 5. The waterproof cylinder 5 and the cap 8 are made of a visible material to facilitate observation of the internal condition of the waterproof cylinder 5 by personnel.

[0034] Preferably, the surface of the fixing plate 4 is provided with a sliding hole 10, and a slider 11 is slidably connected to the inner cavity of the sliding hole 10. One side wall of the slider 11 is fixedly connected to the waterproof cylinder 5 to form a linear guide rail system to guide the waterproof cylinder 5 to move horizontally.

[0035] Preferably, a fixing ring 12 is fixedly connected to the middle of the surface of the ultrapure water detection device 7, and a sealing ring 13 is fixedly connected to the bottom end of the fixing ring 12 to prevent ultrapure water from seeping into the inner cavity of the waterproof cylinder 5 through the through hole 6.

[0036] Preferably, the left and right moving component 9 includes a fixing frame 91 fixed to two side plates 3. A spiral rod 93 is provided on the top of the fixing frame 91. Both sides of the top of the fixing frame 91 are fixedly connected to protrusions 92. A driving part 94 is installed on one side of the protrusion 92. The driving part 94 is a motor, which provides driving force for the rotation of the spiral rod 93. One end of the spiral rod 93 is rotatably connected to the protrusion 92, and the other end of the spiral rod 93 is drively connected to the output shaft of the driving part 94.

The testing head of the pure water testing device 7 extends to the outside through the through hole 6. Then, the cap 8 is rotated, causing the pure water testing device 7 to rotate downwards, driving the fixing ring 12 and the sealing ring 13. While tightening, the fixing ring 12 and the sealing ring 13 come into contact with the inner wall of the waterproof cylinder 5, and the sealing ring 13 is in a compressed state, thereby achieving a seal at the through hole 6. Then, the device is lifted... The device 1 is used to control the downward movement of the pure water testing device 7. After the testing head is submerged in the ultrapure water and left to stand for a period of time to allow the reading to stabilize, the conductivity of the ultrapure water can be tested. During the operation of the pure water testing device 7, the waterproof cylinder 5 is placed with ultrapure water immersed in the upper part of its testing head. The operator can also control the drive unit 94 to drive the spiral rod 93 to rotate, which cooperates with the fixed ball 16, so that the waterproof cylinder 5 drives the pure water testing device 7 to achieve multi-point conductivity testing under the limiting and guiding action of the sliding hole 10 and the slider 11.
