Technical Field

[0001] The utility model relates to the technical field of ultrapure water preparation, in particular to a detection device for ultrapure water preparation which is convenient for sampling. Background Art

[0002] Ultrapure water refers to water with extremely high chemical purity. It is mainly used in biology, chemistry, metallurgy, aerospace, electricity and other fields, but it has very high requirements for water purity. The total organic carbon content in ultrapure water has a great impact on industrial technology experiments. The requirements for organic matter content are different in different industries, so the determination of organic matter is very important.

The preparation pool is arranged on the left side of the fixed table, and the detection platform is installed on the rear side of the fixed table. A rotating base is movably installed inside the fixed table, and a worm gear is fixedly installed on the upper surface of the rotating base, which can realize the transportation of samples and effectively improve the sampling efficiency. The sampling process is not related to the detection process, and continuous multiple sampling can be achieved.

The sampling range is relatively limited, which may affect the accuracy of sampling detection. Based on this, a detection device for ultrapure water preparation that is easy to sample is proposed to solve the above problems. Utility Model Content

The driving component drives the first screw 302 to rotate, thereby causing the transmission wheel 304 on the first screw 302 to rotate, and then drives the transmission wheel 304 on the second screw 303 to rotate through the transmission wheel 304, thereby causing the second screw 303 to rotate, which can drive the second screw 303 to rotate synchronously.

[0027] In addition, the adjustment component includes an adjustment plate 306 threadedly connected between the outer surfaces of the first screw rod 302 and the second screw rod 303, a connecting plate 307 is fixed on the left side of the adjustment plate 306, a mounting seat 308 is fixed on the top of the connecting plate 307, T-blocks 309 are fixed on the front and rear sides of the adjustment plate 306, and the adjustment mechanism 3 also includes a T-slot 310 opened on the front and rear sides of the inner wall of the mounting frame 2, the inner wall of the T-slot 310 and the T-block 309 are slidably connected, so that the movement of the T-block 309 is more stable, thereby providing more guidance for the movement of the adjustment plate 306, a moving hole is opened on the left side of the mounting frame 2, and the connecting plate 307 is slidably connected to the moving hole, and the rotation of the first screw rod 302 and the second screw rod 303 can drive the adjustment plate 306 and the connecting plate 307 to move, so that the position of the sampling component 8 can be moved and adjusted.

[0028] In addition, the sampling component 8 includes a protective box 804 fixed on the upper surface of the preparation pool 7, and the sampling component 8 also includes a water pump 801 fixed on the upper surface of the mounting seat 308.

Jinke cooperates with the sampling component 8 to sample and detect multiple layers of ultrapure water in the preparation pool 7.

[0031] The working principle of the above embodiment is:

[0032] When it is necessary to sample and test the ultrapure water in the preparation pool 7, first start the motor 301 to drive the first screw 302 and the transmission wheel 304 to rotate, and then the second screw 303 to rotate, then the adjustment plate 306 located on the outer surface of the first screw 302 and the second screw 303 will move, and then the connecting plate 307 and the mounting seat 308 can be driven to move, and at this time the T-block 309 follows the movement of the adjustment plate 306 and moves along the inner wall of the T-slot 310, providing a certain guide for the movement of the adjustment plate 306, so that the adjustment plate 306 can move more stably, and then the water pump 801 can be driven more stably. When the water inlet pipe 802 moves, the water inlet pipe 802 can move stably, and then the position of the water inlet of the water inlet pipe 802 inside the preparation tank 7 can be adjusted, so as to facilitate the stratified sampling of ultrapure water liquid inside the preparation tank 7, further expand the sampling detection range, and further improve the detection accuracy. At the same time, when the water inlet pipe 802 moves with the water pump 801, the protective box 804 prevents the part of the water inlet pipe 802 entering the preparation tank 7 from being exposed to the air, thereby preventing the ultrapure water liquid from being contaminated. The operation and application are more convenient. Then, the taken ultrapure water sample is flowed into the sampling cup 5 through the water outlet pipe 803, so as to realize the transportation of the sample.
