Description

Technical Field

[0001] This utility model relates to the field of spray tower technology, specifically to a micro spray tower for sample gas in testing instruments. Background Technology

[0002] In numerous fields such as industrial production, environmental monitoring, and medicine, there is a need for precise detection of the purity and impurity content of sample gases. For example, in the manufacturing process of electronic chips, high-purity sample gases are required for certain processes. Trace amounts of impurities in the gas can affect the quality and performance of the chip, thus necessitating accurate detection of impurities in the sample gas. With the development of technology, various testing instruments are evolving towards miniaturization and portability to facilitate rapid on-site and mobile testing. The micro-spray tower for sample gases used in testing instruments was developed precisely to meet this trend. The micro-spray tower features small size, light weight, and compact structure.

[0003] Traditional detection methods may suffer from insufficient accuracy and inability to detect in real time. However, the sample gas micro spray tower can serve as a pretreatment device. By spraying liquid into full contact with the sample gas, impurities can be removed or the composition can be adjusted, providing a purer sample gas for subsequent accurate detection and meeting the needs of high-precision detection.

[0004] In the spray tower, the spray liquid comes into contact with air, and the liquid after air treatment flows into the water tank below and is eventually discharged. When acidic gases are removed by spraying with an alkaline solution, gases such as carbon dioxide are produced during the reaction. These gases escape into the liquid and form foam. Moreover, some reaction products may change the surface properties of the solution, further promoting the stability of the foam. The foam will have adsorption and buoyancy properties. Finally, when the water tank is emptied, impurities and other particles will adhere to the vertical surface and bottom surface of the water tank, thus increasing the cleaning workload for workers. Utility Model Content

[0005] Given that the spray liquid in the spray tower will come into contact with air, and the liquid after air treatment will flow into the water tank below and eventually be discharged, when using an alkaline solution to spray and remove acidic gases, gases such as carbon dioxide will be produced during the reaction. These gases will form foam when they escape from the liquid. Moreover, some reaction products may change the surface properties of the solution, further promoting the stable existence of foam. The foam will have adsorption and buoyancy properties. Finally, when the water tank is emptied, impurities and other particles will adhere to the vertical surface and bottom surface of the water tank, which will increase the difficulties of cleaning for workers.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments. Example 1

[0024] Reference Figure 1-4 This first embodiment of the present invention discloses a micro spray tower for a testing instrument, comprising: a rectangular mounting platform 1 and a micro spray tower body 2. The micro spray tower body 2 is disposed through the upper surface of the rectangular mounting platform 1, and a processing box 3 is disposed through the lower surface of the micro spray tower body 2. A U-shaped moving plate 4 is disposed inside the processing box 3. A threaded conveying rod is disposed through the vertical surface of the U-shaped moving plate 4. A guide rod is also disposed through the vertical surface of the U-shaped moving plate 4. A scraper 5 is disposed on the vertical surface of the outer side of the U-shaped moving plate 4. A T-shaped loading plate 6 is disposed on the vertical surface opposite to the inner ring of the U-shaped moving plate 4. A protective shell 7 is fixedly connected to the vertical surface of the T-shaped loading plate 6.

[0025] A rectangular support plate 8 is provided on the vertical surface of the protective shell 7. A drive motor 9 is also provided on the upper surface of the rectangular support plate 8. Rotating rods are provided through the vertical surfaces of the T-shaped loading plate 6 and the U-shaped moving plate 4. A transmission wheel 10 is provided through the rod of each of the rotating rods. The cross section of one of the rotating rods is connected to the output end of the drive motor 9. All the transmission wheels 10 are connected to the same output belt 11.

[0026] A rotating sleeve 12 is fixedly connected to the cross section of the rotating rod. An arc-shaped mounting plate 13 is provided on the inner ring of the rotating sleeve 12. Brushes are provided on the opposite arc surfaces of the mounting plate 13. A scraper 14 is fixedly connected to the cross section of one of the rotating rods away from the drive motor 9.

[0027] When in use, the sewage inside the treatment tank 3 should be drained first. This is because a motor is also installed on the vertical surface of the treatment tank 3, and a transmission wheel 10 is installed on the output end of the motor. A threaded conveying rod is installed inside the treatment tank 3, and a U-shaped moving plate 4 is fitted on the rod body of the threaded conveying rod. A pulley is also installed through the rod body of the threaded conveying rod. Therefore, when the motor is started, the threaded conveying rod will rotate, thereby moving the U-shaped moving plate 4. At this time, the drive motor 9 can be started. This is because rotating rods are installed through the vertical surfaces of both the T-shaped loading plate 6 and the U-shaped moving plate 4. A transmission wheel 10 is installed through the rod body of several rotating rods. The cross section of one of the rotating rods is connected to the output end of the drive motor 9, and all the transmission wheels 10 are connected to the same output belt 11.

[0028] Therefore, when the drive motor 9 starts, the transmission wheel 10 will rotate. Since the rotating sleeve 12 is fixedly connected to the cross section of the rotating rod, the guide rod and the threaded conveying rod can be cleaned by the brush when the rotating rod rotates.

[0029] Note: The sewage in the treatment tank 3 is always being discharged and then fed in, and the water level will be below the drive motor 9. There is no possibility of the drive motor 9 malfunctioning. When the sewage drips into the treatment tank 3, there will be splashing. Therefore, the guide rod and the threaded conveyor rod need to be cleaned. Example 2

[0030] Reference Figure 2 and 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the filter box 15 is fixedly connected to the vertical surface of the processing box 3, and a conveying pump 16 is also provided on the vertical surface of the processing box 3. A conveying pipe is also provided on the conveying pump 16, and the conveying pipe passes through and connects to the filter box 15.

[0031] A pair of filter screens 17 are installed on the vertical surface inside the filter box 15, a pair of activated carbon plates 18 are also installed on the vertical surface inside the filter box 15, and a water outlet is opened on the bottom surface inside the filter box 15.

[0032] When in use, the micro spray tower will be in operation. At this time, simply start the delivery pump 16. Because the delivery pump 16 is also equipped with a delivery pipe, which runs through and connects to the filter box 15, the sewage entering the filter box 15 will first come into contact with the filter screen 17. When passing through the filter screen 17, large particles in the sewage can be isolated. Then the sewage will come into contact with the activated carbon plate 18, which will remove small particles of impurities. The filtered water will enter the storage tank through the outlet set on the bottom surface of the filter box 15.

[0033] The remaining structure is the same as that in Example 1.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
