After the centrifugal dehydration of the dithiourea material is completed, the electric push rod 41 is started. The electric push rod 41 drives the connecting seat 42 to move the first gear downward to mesh with the second gear 44, and then controls the positioning motor drive. The first gear rotates, and the positioning motor is a servo motor. The rotation of the first gear causes the drum 19 to rotate slowly. During the rotation, the positioning rod 45 will come into contact with the baffle 46. The housing 12 is provided with an observation window. Observe and listen to the sound of collision, control the positioning motor to stop working, so as to rotate the connecting pipe 37 to a fixed position, so that the connecting pipe 37 and the connecting barrel 17 are positioned and aligned, so that the connecting pipe 37 can be easily inserted into the connecting barrel 17 to reduce hot water leakage at the connection. After the flushing is completed, the electric push rod 41 drives the connection seat 42 and the first gear upward to reset, so that the baffle 46 is separated from the positioning rod 45, and the main shaft 16 drives the drum 19 at high speed. Rotation, friction and heat will be generated during the high-speed rotation. The temperature increase of the drum 19 will increase the temperature of the material solution, but the temperature increase will cause the dithiourea in the material solution to dissolve. When the embodiment of the present invention is used, the spindle 16 rotation will drive the fan blades to rotate. The rotation of the fan blades will suck air from the bottom of the air guide 62, and then inject it into the third annular pipe 52 through the connecting pipe 37, and then spray out from the air outlet slot on the cooling pipe 53. The air outlet slot The jetted air flow can cool the high-speed rotating drum 19 and the connecting tube 17, lowering their temperature, thereby reducing the temperature rise and causing dithiourea to be re-integrated into the material solution. When used, The washed hot water containing dithiourea is collected, and the collected hot water is injected into the cooling tank 61 , and then part of the air flow in the third annular pipe 52 is injected into the top of the air guide 62 through the air pipe 64 , and then Under the action of the uniform distribution plate 66, the airflow is divided into multiple small airflows. The small airflows contact the fins 65, thereby taking away the temperature of the cooling tank 61 and the hot water, thereby dissolving the dissolved water in the hot water collected multiple times. The dithiourea recrystallizes, and then can be injected into the feed pipe 15 through the tube body 63, and then separated again through the drum 19 and the filter cloth 191, thereby separating the dithiourea material in the washing hot water and reducing the To reduce the waste of materials, the corrugated fins 65 are provided to increase the contact area with the air flow and hot water, and the heat conduction effect is improved. The cover body 71 and the air inlet pipe 72 are provided to make the suction cover from the side. Air intake, thereby reducing the inhalation of dithiourea materials during the air intake process. By setting up a filter, the inhaled air can be filtered, thereby reducing blockage in subsequent pipes. During the process of hot water ejection, the spray The impact of the hot water will cause the vibrating plate 82 to vibrate, and then the shaking of the vibrating plate 82 can disturb the water flow, thereby increasing the spray area, thereby improving the washing effect of the filter cloth 191, and relying on the elastic sleeve 91 to The annular plate 192 and the connecting tube 17 are connected and blocked, thereby reducing the entry of dithiourea materials into the annular plate 192, thereby reducing the waste of residual materials there, and reducing the contamination of other materials produced by the residual materials there. Depending on the setting The spring telescopic rod 93 pushes the ring body 92 downward, so that the elastic sleeve 91 can be pulled and stored into the storage cavity, and the elastic sleeve 91 can be stored and rotated by setting the roller 101, thereby reducing the elasticity of the ring body 92 The friction force between the sleeves 91 facilitates the elastic sleeve 91 to be pulled out of the storage groove. By setting the scraper 102, the material on the surface of the elastic sleeve 91 can be scraped, thereby reducing the material entering the storage cavity, thereby reducing the residue in the storage cavity. There is no contamination of other materials produced by dithiourea materials, and the waste of materials is reduced.
