[0026] A motor 3 is provided in the motor seat 2, and the motor output shaft faces the kettle body and is connected to a rotating shaft 4. A bearing seat 5 for fixing the other end of the rotating shaft is provided at the bottom of the kettle body. The rotating shaft 4 is provided with four groups of stirring blade assemblies, and the stirring blade assemblies include two left-right symmetrical stirring blades 16. The stirring blades of the four groups of stirring blade assemblies are staggered from top to bottom at the lower half of the rotating shaft 4.

[0027] A plurality of inclined air inlet pipes 9 penetrating the kettle body are evenly arranged in the circumference of the lower part of the kettle body. The blowing direction of the air inlet pipe 9 is arranged toward the bottom of the kettle body 18, and it mainly serves to cooperate with the stirring device to stir the bottom quartz sand. A filter screen is provided at the air inlet position of the air inlet pipe to block the passage of quartz sand. A horizontal pipe is arranged horizontally at the end of the inclined air inlet pipe 9, and a swing-type one-way valve 10 is installed on the horizontal pipe. A vertical air pipe 11 is connected to the end of the horizontal pipe. The plurality of vertical air pipes 11 are connected to the main pipeline through a multi-way valve, and the main pipeline is connected to the hot air blower. The air inlet pipe is arranged obliquely toward the kettle body, which can better match the stirring device to stir the bottom quartz sand on the one hand, and avoid the phenomenon of backflow of the reaction solution on the other hand.

[0028] The bottom of the kettle body 18 bulges downward, and a discharge port is arranged at the center of the bottom of the kettle body. A valve is welded to the discharge port, and the valve is controlled to open and close by a solenoid valve.

[0029] A support column 12 is circumferentially provided at the bottom of the kettle body 18, and a hollow collecting box 13 is provided below the kettle body inside the support column. The hollow collecting box 13 includes an inner wall 132, an outer wall 121 and a roller 133. A hollow interlayer is provided between the inner wall and the outer wall, and the roller is installed below the outer wall. The hollow interlayer is set as a reaction solution collection chamber, and one side of the outer wall is provided with an acid discharge hole connected to the reaction solution collection chamber; the inner wall is a cone with a larger upper part and a smaller lower part, and the internal space of the inner wall is set as a sand holding chamber, and a hole 134 connected to the reaction solution collection chamber is provided at the bottom of the sand holding chamber, and a filter is provided above the hole.

[0030] During the use of this device, a certain amount of quartz sand is first added through the quartz sand feed port. After the addition is completed, the flap is closed and the air outlet is connected to the exhaust pipe. After the closing is completed, the reaction solution is added through the delivery port through which the reaction solution passes. The reaction solution used in this embodiment is dilute hydrochloric acid. After the addition is completed, it is allowed to stand for 1-2 hours, and then the hot air blower is turned on to blow hot air through the air inlet pipe. The heating temperature of the hot air blower shall not exceed 65 degrees. When the hot air is blown in, the motor is turned on, the motor drives the rotating shaft, and the rotating shaft drives the staggered stirring blades to start fully stirring the quartz sand.

[0031] After the reaction is completed, the solenoid valve is opened to discharge the dilute hydrochloric acid and quartz sand. During the discharge, the air inlet pipe will continue to spray hot air, which can better discharge the quartz sand and play a certain drying role. During this period, workers are not allowed to approach. During the discharge process, the quartz sand and dilute hydrochloric acid are filtered out through the hollow collection box at the bottom. There are rollers at the bottom of the hollow collection box, which can be directly dragged away by workers.
