Abstract

[0002] A defoaming device is a device used to eliminate air bubbles in a solution inside a container.

[0022] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.
[0023] Example
[0024] Reference Figures 1 to 5 An automatic negative pressure defoaming device includes a mounting bracket 1. An airtight component 2, a pressure gauge 6, and a connecting pipe 7 are spaced through on both sides of the mounting bracket 1. The pressure gauge 6 and the connecting pipe 7 are spaced inside the airtight component 2. One end of the connecting pipe 7 is connected to an external negative pressure device. A positioning component 3 is provided on one side of the mounting bracket 1. A support rod 4 is spaced outside the positioning component 3. A laser sensor 5 is fixedly installed on the upper end of the support rod 4. The airtight component 2 is used to ensure the airtightness around the reagent bottle during negative pressure defoaming. The positioning component 3 is used to fix the reagent bottle and tap the reagent bottle to promote defoaming. The support rod 4 is used to fix the laser sensor 5. The laser sensor 5 is used to detect whether the reagent bottle is placed on the positioning component 3. The pressure gauge 6 is used to detect the air pressure value inside the airtight component 2 during negative pressure defoaming.
[0025] The positioning component 3 includes a positioning ring 31 and a limiting component 32 that are connected to one side of the mounting bracket 1 by bolt thread. The limiting component 32 is located below the positioning ring 31. A through hole is provided at the center of the positioning ring 31. The laser sensor 5 is located on the same vertical plane as the center of the through hole. A knocking component 33 is provided vertically through the limiting component 32. Multiple sets of knocking components 33 are arranged in a ring at intervals. The positioning ring 31 and the limiting component 32 are used to limit the position of the reagent bottle. The knocking component 33 is used to knock the reagent bottle to promote defoaming. The laser sensor 5 can detect whether the reagent bottle is placed at the position of the through hole.
[0026] The airtight component 2 includes a first electric telescopic rod 21 fixedly connected to one side of the mounting bracket 1. One end of the first electric telescopic rod 21 is fixedly connected to a parallel connecting rod 22. Guide rods 23 are fixedly connected to both ends of the parallel connecting rod 22. The first electric telescopic rod 21 can control the lateral movement of the parallel connecting rod 22 and the two sets of guide rods 23.
[0027] Both sets of guide rods 23 are movably connected to the mounting bracket 1. One end of each set of guide rods 23 is fixedly connected to an airtight chamber 24. A sealing ring is fixedly connected to a section of the airtight chamber 24 near the mounting bracket 1. The first electric telescopic rod 21 enables the two sets of guide rods 23 to move the airtight chamber 24, thereby enabling the airtight chamber 24 to be squeezed and sealed against one side of the mounting bracket 1.
[0028] The limiting component 32 includes a fixed base 321 that is threadedly connected to one side of the mounting bracket 1 by bolts, and the position of the fixed base 321 is adjustable. A first magnetic block 322 is embedded and fixedly connected to the upper end of the fixed base 321, and an embedded ring 323 is fixedly connected to the upper end of the fixed base 321. A placement cylinder 324 is contacted and disposed at the upper end of the fixed base 321. A second magnetic block 325 is fixedly connected to the lower end of the placement cylinder 324, and the second magnetic block 325 is magnetically connected to the first magnetic block 322. The placement cylinder 324 and the embedded ring 323 are movably fitted together. The horizontal movement of the placement cylinder 324 can be restricted by the embedded ring 323, and the vertical movement of the placement cylinder 324 can be restricted by the first magnetic block 322 and the second magnetic block 325.
[0029] A second electric telescopic rod 327 is fixedly connected to the lower surface of the fixed base 321. A connecting plate 328 is fixedly connected to the lower end of the second electric telescopic rod 327. A cavity 326 is opened inside the fixed base 321. The connecting plate 328 can be moved vertically by the second electric telescopic rod 327.
[0030] The striking component 33 includes a third electric telescopic rod 331 embedded and fixedly connected to one side of the cavity 326. One end of the third electric telescopic rod 331 is fixedly connected to a sliding block 332, and the sliding block 332 is slidably connected to the upper end of the fixed seat 321. The sliding block 332 can be controlled to slide inside the fixed seat 321 by the third electric telescopic rod 331.
[0031] A spring rod 334 is fixedly connected to the upper end of the sliding block 332. A rubber ball 335 is fixedly connected to the upper end of the spring rod 334. A connecting rope 333 is fixedly connected to the outer surface of the spring rod 334 near the upper end. One end of the connecting rope 333 is fixedly connected to the outer surface of the connecting plate 328. A clearance hole is provided on the fixed seat 321 for the connecting rope 333 to move. When the second electric telescopic rod 327 extends and causes the connecting plate 328 to move downward, the connecting rope 333 will pull the spring rod 334 to deform away from the placement cylinder 324. When the second electric telescopic rod 327 retracts quickly, the spring rod 334 will drive the rubber ball 335 to swing back and forth under the action of elasticity.
[0032] In use, this invention first adjusts the position of the fixed base 321 and the mounting bracket 1 according to the size of the reagent bottle to be defoamed. Then, the placement cylinder 324 is lifted upward to separate it from the fixed base 321. Next, the placement cylinder 324, matching the size of the reagent bottle to be defoamed, is placed on the fixed base 321. The placement cylinder 324 is fixed by the embedded ring 323, the second magnetic block 325, and the first magnetic block 322. The placement cylinder 324 can be replaced with a simple plug-and-play operation, making it easy to operate and use. Then, the position of the sliding block 332 and the elastic rod 334 is adjusted by the third electric telescopic rod 331, so that all eight sets of rubber balls 335 are close to the outside of the reagent bottle. During the negative pressure defoaming process, the reagent bottle is placed in the upper groove of the placement cylinder 324 by the external clamping and conveying device. At this time, the reagent bottle passes through the through hole of the positioning ring 31. After the laser sensor 5 detects that the position of the reagent bottle meets the requirements, the first electric telescopic rod 21 makes the airtight chamber 24 contact and press against the mounting bracket 1 for sealing. Then, the outer... The negative pressure device draws air from the inside of the airtight chamber 24 through the connecting pipe 7, maintaining a negative pressure inside the chamber 24. This allows air bubbles in highly viscous reagents to rise and be expelled, thus achieving negative pressure defoaming. During the defoaming process, the connecting plate 328 moves downward a certain distance and then quickly rises after a three-second interval, repeating the movement of the connecting plate 328. This causes the eight sets of rubber balls 335 to continuously reciprocate, continuously tapping the outside of the reagent bottle. This promotes the rise of air bubbles adhering to the side wall of the reagent bottle, improving the defoaming effect. The circular arrangement of the eight sets of rubber balls 335 ensures that the tapping point simultaneously covers the entire side wall of the reagent bottle, resulting in a more uniform energy distribution and better defoaming effect. At the same time, the tapping method avoids the generation of new air bubbles from violent vibrations. This invention can achieve automatic negative pressure defoaming of highly viscous reagents and can be used with reagent bottles of different sizes. In use, the combination of negative pressure defoaming and tapping defoaming methods effectively improves the defoaming effect and efficiency.
