[0002] As we all know, the large-scale industrial production of granular materials must do a good job in dust pollution prevention and control. Therefore, in accordance with the national dust pollution prevention and control standards, most of them adopt wet preparation technology. In the preparation technology of non-metallic mineral granular materials, almost all of them adopt wet production technology. The biggest advantage of this process is to maximize the removal of iron introduced in the process of preparing granular materials through wet magnetic separation. However, after the granular materials are prepared, their specific surface area increases, the surface energy is large, the adsorption capacity also increases, and the ability to adsorb impurities is strong - the impurities adsorbed on its surface include not only liquids, solids but also gases. Therefore, the removal When the granular material after water enters the pickling tank, there are gaps between the materials when they are piled up, and the gaps are filled with air. Therefore, during the acid purification process in the acid purification device (such as: Patent No. 2013102794006, Patent Name: Method for preparing low-iron quartz sand for photovoltaic glass from pyrite-type quartz rock and pickling purification device), when the acid enters from the bottom of the pickling tank, it slowly rises, and the air is slowly driven out during the rising process, thus forming a lot of foam. If the foam cannot be effectively removed, it will have an adverse effect on the normal flow of the acid in the pickling process. Utility Model Content

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown, a particle material purification countercurrent pickling device comprises:

[0024] The pickling tank 1 is formed by connecting an upper cylinder with a lower cone. A sand discharge port with a valve is provided on the cone of the pickling tank 1. The structure is designed to facilitate the discharge of accumulated sand in the pickling tank 1.

[0025] The acid inlet of the pickling tank 1 is located at the bottom of the pickling tank. The acid inlet is connected in series with the heater 3, the acid-resistant pump 4 and the acid storage container 5 in sequence through the acid delivery pipe 2. The acid-resistant pump 4 is started, and the acid in the acid storage container 5 is sent into the heater 3 through the acid-resistant pump 4, and then sent into the pickling tank 1 after being heated by the heater 3.

[0026] An overflow groove 120 is provided on the outer edge of the upper cover 110 of the pickling tank 1. The overflow groove 120 is connected to the tank body 7 through the overflow pipe 6. The acid liquid after the foam is eliminated in the pickling tank 1 can overflow to the overflow groove 120 through the overflow port, and then flow to the tank body 7 through the overflow pipe 6.

[0027] The upper cover 110 is provided with a feeding port 111 , through which non-metallic mineral granular materials can be fed into the pickling tank 1 .

[0028] A plurality of ultrasonic vibrating rods 8 extending below the liquid level in the pickling tank 1 are fixed on the upper cover 110 of the pickling tank 1. The specific number of ultrasonic vibrating rods 8 installed is determined according to the radial cross-sectional area of ​​the pickling tank 1. The ultrasonic vibrating rods 8 are evenly distributed along the cross-sectional direction of the top of the pickling tank 1, and the bottom end of the ultrasonic vibrating rod 8 is 30 mm away from the liquid level in the pickling tank 1; the ultrasonic vibrating rods 8 are connected to the ultrasonic generator 9. When the acid liquid rises to the overflow port near the upper end of the pickling tank 1, the ultrasonic generator 9 is turned on. The ultrasonic generator 9 controls the ultrasonic vibrating rod 8 to generate ultrasonic vibrations and emits this vibration energy into the liquid, thereby utilizing the cavitation effect of the ultrasonic wave to quickly burst the foam on the floating liquid surface to eliminate the foam.

[0029] The workflow is as follows:

[0030] The non-metallic mineral granular material to be pickled and purified is fed into the pickling tank 1 through the feed port 111, and the amount of the added material is determined according to the actual situation;

[0031] After the feeding is completed, the acid-resistant pump 4 is started, and the acid solution in the acid storage container 5 is sent to the heater 3 through the acid-resistant pump 4, and then sent to the pickling tank 1 after being heated by the heater 3;

[0032] When the acid liquid rises to the overflow port near the upper end of the pickling tank 1, the ultrasonic generator 9 is turned on. The ultrasonic generator 9 controls the ultrasonic vibration rod 8 to generate ultrasonic vibration and emits this vibration energy into the liquid, thereby utilizing the cavitation effect of the ultrasonic wave to quickly burst the foam on the floating liquid surface to eliminate the foam. After the foam is completely eliminated, the ultrasonic generator 9 can be turned off.
