Specific Embodiments

[0024] The following will describe two implementation manners of the present application in detail with reference to the accompanying drawings.

[0025] The first implementation manner:

[0026] Figures 1-4 and Figure 7 Disclosed is a separation and extraction device for a 2,4-dichloro-5-fluoroacetophenone synthesis solution, including a drying device 1 with a drying oven 7. A viewing door 3 is rotatably connected to the side of the drying oven 7. A heater 2 is installed on the inner wall of the drying oven 7. A bottom shaft 21 is fixedly connected to the middle of the drying oven 7. A placement mechanism is detachably connected to the top of the bottom shaft 21. The placement mechanism includes a mounting shaft 9 detachably connected to the bottom shaft 21. A slot 12 is drilled at the top of the bottom shaft 21. A first clamping block 13 is fixedly connected to the bottom of the mounting shaft 9, and the first clamping block 13 is engaged with the slot 12. A bracket 10 is sleeved on the side wall of the mounting shaft 9 at the bottom. A tray 5 is sleeved on the mounting shaft 9 above the bracket 10. A servo motor 20 is fixedly connected in the drying device 1. The output end of the servo motor 20 is connected to a rotating shaft 8, and the top of the rotating shaft 8 is sleeved outside the bottom shaft 21 in a groove shape. A connecting rod 11 is fixedly connected to the side wall of the rotating shaft 8. A connecting rod 23 is detachably connected to the connecting rod 11. A group of clamping plates 22 are installed at one end of the connecting rod 23 close to the mounting shaft 9. A scraping plate 6 is rotatably connected between the clamping plates 22 through a damping rotating shaft, and the damping rotating shaft is set to flip upwards by 90 degrees. A plurality of scraping teeth 19 are fixedly and equidistantly connected to the bottom end of the scraping plate 6, and the scraping teeth 19 are in contact with the inner bottom of the tray 5. A controller 4 for controlling the servo motor 20 and the heater 2 is fixedly connected to the drying device 1 below the drying oven 7.

[0027] This solution can achieve: When drying the separated and extracted 2,4-dichloro-5-fluoroacetophenone synthesis solution, first flip the scraping plate 6 upwards by 90 degrees, then place the material on the tray 5, and then sleeve the tray 5 on the mounting shaft 9. The bottom is supported by the bracket 10 at the bottom. At this time, flip the scraping plate 6 back to its original position so that the scraping teeth 19 are located in the tray 5 and in contact with its bottom. Then, engage and fix the first clamping block 13 at the bottom of another mounting shaft 9 in the slot 12 at the top of the lower mounting shaft 9. Again, sleeve a tray 5 filled with material on the upper mounting shaft 9. Multiple layers can be placed in sequence to dry the material. At this time, after closing the viewing door 3, turn on the heater 2 and the servo motor 20 simultaneously through the controller 4. The heater 2 dries the material, and the servo motor 20 drives the rotating shaft 8 to drive the scraping plate 6 on the connecting rod 11 to rotate, turning the material in the tray 5, so that the material can be evenly heated during the drying process, avoiding the problem of over-drying in some areas and insufficient drying in some areas.

[0028] The second implementation manner:

[0029] Figures 3-6It is shown that a slot 15 is carved on the top of the scraper 6 away from the scraping teeth 19, and a second block 14 corresponding to the slot 15 is fixedly connected to the bottom end of the scraper 6, and the two adjacent scrapers 6 are engaged with the slot 15 through the second block 14, and the second block 14 and the side ends of the slot 15 are fixedly connected with the corresponding bottom shaft 21, and the bottom shaft 21 and the slot 15 are threadedly connected by bolts 16. A plurality of air holes are provided on the tray 5, and the middle part of the tray 5 is sleeved on the mounting shaft 9 through a circular hole, and a waterproof and breathable pad 17 is placed on the inner wall of the tray 5. The top of the tray 5 is detachably connected to a limit ring 18, and an annular groove is provided at the bottom end of the limit ring 18, and the annular groove is engaged with the top of the tray 5.

[0030] This solution can be achieved as follows: before placing the material on the tray 5, the waterproof and breathable pad 17 can be laid inside the tray 5 and locked to prevent the water vapor generated during the drying of the material from flowing into the material below, and then the limiting ring 18 is clamped on the top of the tray 5 through the annular groove. At this time, the waterproof and breathable pad 17 is clamped between the tray 5 and the waterproof and breathable pad 17, and the waterproof and breathable pad 17 is positioned. Then the material can be laid on the tray 5 for drying. After the trays 5 are successively put on the mounting shaft 9, the corresponding scraper 6 is selected according to the number of trays 5, and the second clamping block 14 at the bottom is locked with the clamping groove 15 on the top of the adjacent scraper 6 and positioned, and then threaded fixed with the bolt 16 and the bottom shaft 21. The scraper 6 can be conveniently disassembled and assembled, making it easy to take and place the tray 5.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
