Description

Gas jet mixing system and mixing of liquid deposits Mixing method

The invention relates to a gas jet stirring system and a stirring method, and particularly relates to a gas jet stirring system and a stirring method applied to agitating a liquid in a liquid, thereby improving the uniformity of distribution of the deposit in the liquid and extending the device. Service life and reduce labor costs.

In order to confirm the presence or absence of cracks on the surface of the steel material, non-destructive magnetic particle inspection is generally applied. The above-mentioned flaw detection test utilizes the surface of the steel material to sprinkle the liquid containing the fluorescent magnetic powder and cooperates with the AC and DC power, so that the fluorescent magnetic powder is concentrated in the crack due to the magnetic force line, and the crack is revealed by artificially searching in the dark room by using the ultraviolet lamp. The remaining phosphor-containing liquid remaining after use is recovered by a reflux system and can be reused.

However, the above-mentioned liquid containing the fluorescent magnetic powder sprayed on the surface of the steel material is stored in the accommodating tank for a long period of time, and the fluorescent magnetic powder is likely to precipitate at the bottom of the accommodating groove, adhere to the side wall of the tank or adhere to each other and aggregate. In other cases, the phosphor powder in the liquid is unevenly distributed, causing it to spill on the surface of the steel material. The concentration of the fluorescent magnetic powder is too high or too low, and there is a disadvantage that the appearance of the crack cannot be completely exhibited. The above situation cannot be effectively improved even by the circulation suction of the suction pump.

In addition, in the common water treatment process, the natural sedimentation method is used to accumulate the sediment in the water at the bottom of the sedimentation tank, but the sediment accumulated for a long time is not easy to be cleaned, which causes the volume of the sedimentation tank to be reduced.

In view of the above problems, it is common to manually use a brush to agitate the deposit (fluorescent magnetic powder or sediment, etc.) in the receiving tank to homogenize the deposit in the liquid or to clean the tank. However, the bristles on the brush are easily detached during use, which causes defects such as blockage or damage of the pipeline of the device, thereby reducing the service life of the device, and labor is also increased by using labor.

There are some common methods for using fixed-point gas agitation, which is to fix the gas orifice to the side wall or the center of the accommodating tank to provide a stirring gas. However, the fixed-point gas cannot stir the deposits on the edges or corners, so the stirring effect is not good.

Therefore, there is an urgent need to provide a stirring system and a stirring method which can achieve a good stirring effect and improve the disadvantages of the conventional stirring system and the stirring method, such as bristle blockage, pipeline damage, high labor cost, and low equipment service life.
