[0018] S2: setting programmable controller parameters according to historical concentration crystallization conditions;

[0020] S4: starting the circulating pump through the programmable controller, the circulating pump pumping the cooling water in the refrigeration water tank to the cooling pipe and then back to the refrigeration water tank through the cooling pipe to realize circulating refrigeration, so that the concentration crystallization cavity presents the required temperature for concentration crystallization, and the stannous chloride solution in the concentration crystallization tank is concentrated and crystallized;

[0021] S5: The programmable controller controls the electromagnetic iron to be electrified and the first motor to be started. The electromagnetic iron is electrified to adsorb the cross block to move upward until it is adsorbed to stop. At this time, the cross block enters the first cross slot to connect the fifth driving shaft and the first screw rod. The first motor drives the output shaft to rotate forward to drive the second bevel gear to rotate forward. The second bevel gear drives the first bevel gear to rotate forward. The first bevel gear drives the support shaft to rotate forward. The support shaft drives the connected first pulley to rotate forward. The connected first pulley drives the first transmission belt to rotate forward through friction transmission. The first transmission belt drives the other first pulley to rotate forward. The other first pulley drives the fifth driving shaft to rotate forward. The fifth driving shaft drives the first screw rod to rotate forward. In the process of rotating forward, the filter screen frame drives the crystallized stannous chloride crystals in the concentration crystallization box to move upward on the first screw rod until the set parameters are reached. The programmable controller controls the electromagnetic iron to be de-energized. The cross block moves downward under the action of the two second connecting springs and is accommodated in the second cross slot. The fifth driving shaft and the first screw rod are disconnected. The first screw rod does not act to drive the filter screen frame to stop acting. At this time, the filter screen frame is located at the top end of the concentration crystallization box. The programmable controller controls the second motor to be started. The second motor drives the output shaft to rotate forward to drive the first driving shaft to rotate forward. The first driving shaft drives the two hollow worms to rotate forward. The two hollow worms drive the two worm gears to rotate forward. The two worm gears drive the two second screw rods to rotate forward. In the process of rotating forward, the two movable rods move toward the filter screen frame. The two movable rods drive the push plate to move in the same direction. In the process of moving, the push plate pushes the stannous chloride crystals on the filter screen frame into the collection rack until the set parameters are reached. The programmable controller controls the electromagnetic iron to be electrified and the first motor to be reversely driven to drive the filter screen frame to reset until the set parameters are reached. The programmable controller controls the electromagnetic iron to be de-energized. The programmable controller controls the second motor to be reversely driven to drive the push plate to reset. In the process of resetting, the two movable rods move away from the filter screen frame in the reverse direction. In the process of moving, the two movable rods squeeze the two first racks. The two first racks and the two movable rods move in the same direction to drive the two first gears to rotate counterclockwise. The two first gears drive the two second racks to move toward the filter screen frame. In the process of moving, the two second racks drive the two second gears on the two fourth driving shafts to rotate counterclockwise. The second gears on the two fourth driving shafts drive the two second gears connected to the two ends of the connecting shaft to rotate clockwise. The two second gears drive the connecting shaft to rotate clockwise. The connecting shaft drives the collection rack to rotate clockwise. In the process of rotating and tilting, the stannous chloride crystals in the collection rack continuously fall on the classification disc. The rotating support shaft continuously pushes the stannous chloride crystals on the classification disc. The stannous chloride crystals fall from the crystal dropping port that meets the specifications into the air drying box below. Then, the stannous chloride crystals fall into the crystal collection box below through the air drying box outlet, waiting for the staff to take them.

[0022] S6: When the stannous chloride crystals fall into the air-drying box from the crystal dropping hole meeting the specification, the first transmission belt drives the third belt pulley to rotate through friction transmission, the third belt pulley drives the seventh drive shaft to rotate, the seventh drive shaft drives the third gear to rotate, the third gear drives the fourth gear to rotate, the fourth gear drives the connected second drive shaft to rotate, the connected second drive shaft drives the connected second belt pulley and the fourth bevel gear to rotate, the connected second belt pulley drives the second transmission belt to rotate through friction transmission, the second transmission belt drives the other second belt pulley to rotate through friction transmission, the other second belt pulley drives the connected second drive shaft to rotate, the other second drive shaft drives the fourth bevel gear to rotate, the fourth bevel gear drives the third bevel gear to rotate, the third bevel gear drives the sixth drive shaft to rotate, and the sixth drive shaft drives the blowing fan to rotate. The blowing fan blows the cold air of the cooling pipe into the air-drying box through the air-drying hole to air-dry the water spots on the surface of the stannous chloride crystals.

[0023] Compared with the prior art, the beneficial effects of the present application are:

[0024] 1、The present application pushes out the stannous chloride crystals that have been concentrated and crystallized during the crystallization process according to historical crystallization data to set parameters, avoids the influence of the concentrated and crystallized stannous chloride crystals on the concentration and crystallization speed of the stannous chloride solution, improves the concentration and crystallization speed of the stannous chloride solution, and the pushed-out stannous chloride crystals can be collected from the crystal dropping holes of different diameters under the push of the rotating classification plate, thereby saving time and effort of subsequent personnel to take out the stannous chloride crystals and classification work.

[0025] 2、The cooling pipe of the present application is wound on the air-drying box in addition to the concentration and crystallization box, and cold air is blown into the air-drying box by multiple blowing fans during the classification and dropping process of the stannous chloride crystals, so that the water spots on the surface of the stannous chloride crystals can be air-dried, thereby saving time and effort of subsequent personnel to air-dry.

[0026] 3、The present application is equipped with a rotating drive mechanism between the first screw rod and the supporting shaft, which is driven by the same driving source, thereby ensuring smooth operation and energy saving and environmental protection. BRIEF DESCRIPTION OF DRAWINGS
