[0002] Aluminum isopropoxide, also known as isopropyl aluminum oxide, is a white crystalline solid, lumpy substance, or powder with strong hygroscopic properties. It decomposes in water to form aluminum hydroxide. At room temperature, it is a tetramer. It is prepared by the reaction of metallic aluminum and isopropanol in the presence of a catalyst, or by the reaction of aluminum trichloride and sodium isopropoxide. It is used as a reducing agent and a strong dehydrating agent in the synthesis of reducing compounds and organic compounds.
[0003] This application addresses the shortcomings of existing technologies. In existing technologies, aluminum isopropoxide generates a large amount of dust during crushing and processing. This dust is collected by a dust recovery device, and then the dust in the collection box is cleaned and collected centrally. Aluminum isopropoxide is highly hygroscopic, decomposes into aluminum hydroxide when it comes into contact with water, is highly flammable, reacts violently with water, and is irritating to the respiratory system. Therefore, if the collection box becomes damp, it can easily cause danger. Utility Model Content

The bottom of the collection box 8 has an air vent 15 on one side, which is connected to the drying tank 12. The bottom of the collection box 8 is fixedly connected to a fixing seat 13, and the two sides of the fixing seat 13 are slidably connected to symmetrically distributed locking rods 21. The bottom of the recycling box 1 is fixedly connected to symmetrically distributed fixing blocks 16, and the fixing blocks 16 have slots 22 that are compatible with the locking rods 21. Hot air is introduced into the connecting groove 7 through the hot air pipe 24. The hot air enters the drying tank 12 through the connecting groove 7 to dry the collection box 8, thus preventing the collection box 8 from being damp and causing the collected aluminum isopropoxide dust to react violently with water.
[0017] The top outer wall of the recycling box 1 is fixedly connected to a first fan 4. The air outlet of the first fan 4 is fixedly connected to a hot air pipe 24. The air inlet of the first fan 4 is fixedly connected to a duct 5. Hot air is introduced into the hot air pipe 24 through the duct 5 and the first fan 4 to dry the collection box 8.
[0018] Among them, the end of the lever 21 that extends into the fixed base 13 is fixedly connected to a rack 17. The rack 17 is slidably connected to the inner wall of the fixed base 13. The two racks 17 are centrally symmetrically distributed. The bottom inner wall of the fixed base 13 is rotatably connected to a rotating shaft 19. The outer wall of the rotating shaft 19 is fixedly sleeved with a transmission gear 18, and the transmission gear 18 meshes with the rack 17. Through the cooperation of the transmission gear 18 and the rack 17, when one rack 17 moves, it can drive the other rack 17 to move in the opposite direction.
[0019] Among them, springs 14 are fixedly connected to the two racks 17 on the side that are far apart from each other, and the other end of the springs 14 is fixedly connected to the inner wall of the fixed base 13. The springs 14 are sleeved with the locking rod 21. The locking rod 21 and the racks 17 can be reset after moving through the springs 14, so that the locking rod 21 can enter the locking groove 22 to limit the collection box 8.
[0020] The fixed base 13 has centrally symmetrically distributed sliding grooves 23 on both sides. The inner wall of the sliding groove 23 is slidably connected to a lever 20, and the lever 20 is fixedly connected to the rack 17. The lever 20 can be used to easily push the rack 17 to move.
[0021] The recycling bin 1 has a through groove 10 on the side away from the crushing bin 2. A filter screen 11 is fixedly connected to the inner wall of the through groove 10.

[0022] The bottom of the recycling bin 1 is provided with a positioning groove 9, which is adapted to the collection box 8. The positioning groove 9 facilitates the installation of the collection box 8.
[0023] Working principle and usage process of this utility model: In this application, during installation, pushing the collection box 8 causes it to enter the positioning groove 9, and the hot air pipe 24 enters the connecting groove 7. Pulling one of the levers 20 causes the lever 20 to move, which in turn moves the rack 17. The rack 17 moves through the transmission gear 18, causing the other rack 17 to move, which in turn causes the two locking rods 21 to enter the fixing seat 13. The spring 14 is stretched. When the top of the collection box 8 abuts against the top inner wall of the positioning groove 9, the locking rods 21 and the locking groove 22 are on the same straight line. At this time, releasing the lever 20 causes the spring 14 to reset, which in turn causes the two locking rods 21 to reset. The locking rods 21 enter the locking groove 22 to fix the collection box 8, which is convenient for installation and disassembly, convenient for cleaning, and thus concentrates the dust, ensuring that the hot air pipe 24 enters the connecting groove 7. In actual use, a sealing ring can be added to the bottom outer wall of the hot air pipe 24 to ensure a seal between the hot air pipe 24 and the connecting groove 7 after the collection box 8 is installed, thus ensuring the ventilation and drying effect. In this application, during use, hot air is introduced into the drying tank 12 through the first fan 4 and the duct 5 via the hot air pipe 24 and the connecting groove 7. The hot air flows in the drying tank 12 to dry the collection box 8. The drying tank 12 has an S-shaped structure, which helps to increase the circulation time of the hot air in the collection box 8 and ensure the drying effect. After drying, the dust generated by crushing in the crushing box 2 is transported to the recycling box 1 through the conveying pipe 3 by the second fan 6 for recycling.
