Technical Field

[0001] This utility model relates to the field of nitrogen humidification, and in particular to an automatic humidification mechanism for grinding fluid. Background Technology

[0002] A nitrogen humidifier is a device used to add moisture to a nitrogen stream to achieve a specific humidity level. It is commonly found in industrial and laboratory environments to meet specific production or experimental needs. For example, in the food industry, nitrogen is used in packaging to prevent oxidation, and humidity helps maintain the freshness of food. In chemical reactions, humidity can affect the progress of certain chemical reactions. In electronics manufacturing, humidity can affect the process results when soldering or other processes are performed in a nitrogen environment, so strict humidity control is required.

[0003] Existing nitrogen humidifiers insert a gas tube into water, and produce wet nitrogen through the contact between nitrogen and water. With this method, the humidity of the nitrogen cannot reach the requirement of ≤95%, which may cause crystallization of the grinding fluid during use, thus increasing the cost. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that nitrogen and ultrapure water cannot be fully mixed together and the nitrogen humidity cannot meet the requirements, and to propose an automatic humidification mechanism for grinding fluid.

[0009] Preferably, the wet nitrogen outlet connector is located at the top of the top cover plate, the inlet flared connector is located on the side of the top cover plate, and the wet nitrogen outlet connector passes through the top cover plate and forms an opening at the bottom of the top cover plate.

[0010] Preferably, a sensor mounting bracket is installed on the liquid storage tank, and a non-contact liquid level sensor is installed on the sensor mounting bracket to detect the liquid level in the liquid storage tank.

[0019] Example 1

[0020] like Figures 1-3 As shown, the present invention proposes an automatic humidification mechanism for grinding fluid, including a mounting plate 12, and further comprising:

[0021] The top cover plate 1 is set on the mounting plate 12. The top cover plate 1 has a cavity inside. The top cover plate 1 is provided with a wet nitrogen outlet connector 9 and an inlet flared connector 6. The bottom of the top cover plate 1 is provided with an outlet. In this utility model, there are two outlets. The inlet flared connector 6 is used to connect to the pure water conveying pipe.

[0022] The intermediate body 2 is mounted on the mounting plate 12 and located below the top cover plate 1. The intermediate body 2 has an internal cavity. A buffer tank 10 is placed between the intermediate body 2 and the top cover plate 1. An air inlet flared connector 5 is provided on the intermediate body 2. The air inlet flared connector 5 is used to connect to the nitrogen input pipeline and to introduce nitrogen into the intermediate body 2. A water suction pipe 13 is provided at the bottom of the intermediate body 2, and a nozzle 7 is provided at the top. A drain hole is provided on the intermediate body 2. The drain hole is not connected to the internal cavity of the intermediate body 2. The drain hole forms an opening on both the upper and lower end faces of the intermediate body 2. In this utility model, two drain holes and two nozzles 7 are provided. The nozzles 7 are connected to the internal cavity of the intermediate body 2. When nitrogen enters, pure water is drawn up from the water suction pipe 13 through the siphon effect and sprayed out from the nozzles 7.

[0023] And the base 3, which is set on the mounting plate 12 and located below the middle body 2, has a cavity inside the base 3, and a liquid storage tank 14 is set between the base 3 and the middle body 2.

[0024] Example 2

[0025] like Figures 1-3 As shown, this utility model proposes an automatic humidification mechanism for grinding fluid. Compared with Embodiment 1, this embodiment introduces the detailed structure.

[0026] The wet nitrogen outlet connector 9 is located at the top of the top cover plate 1, and the inlet flared connector 6 is located on the side of the top cover plate 1. The wet nitrogen outlet connector 9 passes through the top cover plate 1 and forms an opening at the bottom of the top cover plate 1. A sensor mounting bracket 4 is installed on the storage tank 14, and a non-contact liquid level sensor, such as an ultrasonic liquid level transmitter or a radar liquid level transmitter, is installed on the sensor mounting bracket 4 to detect the liquid level in the storage tank 14. When the liquid level reaches the set height, the pure water supply stops. The top cover plate 1 and the buffer tank 10, the intermediate body 2 and the buffer tank 10, the intermediate body 2 and the storage tank 14, and the storage tank 14 and the base 3 are all connected by adhesive. A drain port connector 8 is installed on the base 3, and the drain port connector 8 is threadedly connected to the base 3. An exhaust port flared connector 11 is provided on the top cover plate 1. The exhaust port flared connector 11 and the water inlet flared connector 6 are located on both sides of the top cover plate 1, respectively. The exhaust port flared connector 11 has a small diameter and is used to discharge excess wet nitrogen, so that the excess wet nitrogen is discharged into the exhaust equipment.

[0027] In summary, during use, ultrapure water enters the top cover 1 through the inlet flared connector 6 and then falls through the two outlets. Simultaneously, nitrogen enters the intermediate body 2 through the inlet flared connector 5 and is ejected through the nozzle 7. Through a siphon effect, the suction pipe 13 draws pure water from the storage tank 14 up and ejects it along with the nitrogen through the nozzle 7, completing nitrogen humidification. The nitrogen in the buffer tank 10 will also have secondary contact with the falling water, further improving the humidification effect. Finally, the wet nitrogen is discharged from the wet nitrogen outlet connector 9. The exhaust flared connector 11 is not closed; it simply has a small diameter. Most of the wet nitrogen will enter the required point through the wet nitrogen outlet connector 9. Only when the pressure at the required point is too high will it be discharged into the exhaust fan through the exhaust flared connector 11. This invention can achieve a nitrogen humidity of over 95%.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
