[0030] The quantitative liquid inlet module 4 comprises a micro motor 401 , on which a limit turntable 402 is mounted, and a surface of the limit turntable 402 is in contact with a limit rod 403 .

[0031] The limiting rod 403 is connected with a spring 404 , which is mounted on a fixing block 405 . The limiting rod 403 is provided with two protrusions 406 , and a tooth 407 is placed between the two protrusions 406 .

[0032] The teeth 407 are arranged on the rotating shaft 408 , and a small gear 409 is mounted on the rotating shaft 408 . A large gear 410 is meshedly connected to the surface of the small gear 409 , and a ring 411 is arranged on the inner surface of the large gear 410 .

[0037] The feed inlet 12 is rotatably connected to the fine extraction device 11 , and the feed inlet 12 is also provided on the coarse extraction device 3 .

[0038] How this utility works:

[0039] Refer to the instruction manual Figure 1-4 When using the device, first connect the extraction liquid to the liquid inlet pipe 1 through the liquid inlet pipe 1, and then transport the slag raw materials to be extracted from the feed port 12 into the rough extraction device 3, open the switch valve 2, and the extraction liquid in the liquid inlet pipe 1 will be preferentially injected into the rough extraction device 3. After the extraction liquid fills the extraction liquid chamber 7, the coarse filter screen 6 starts to move up and down continuously, and the raw materials on the coarse filter screen 6 are continuously soaked in the extraction liquid chamber 7 and then rise to dry. The process is repeated many times to dissolve the extract in the slag of the raw materials into the extraction liquid chamber 7, and the valve on the discharge port 9 at the bottom of the rough extraction device 3 is opened, and the fully dissolved slag liquid is discharged from the discharge port 9 to complete the rough extraction process. Of course, the liquid adding pipe 10 on the rough extraction device 3 can also add a dissolving agent to the dissolved substance again to achieve secondary extraction;

[0040] Refer to the instruction manual Figure 4-7When using the device, after the initial extraction process, the quantitative liquid inlet module 4 can be started to continuously increase the amount of solvent in the extraction liquid chamber 7 to achieve the purpose of accelerating the dissolution efficiency. After starting the micro motor 401, the limit turntable 402 is driven to rotate, so that the limit rod 403 is pushed toward the end of the liquid inlet pipe 1, and the protrusion 406 is driven to push the tooth 407, so that the small gear 409 drives the large gear 410 to rotate, and the rotation of the large gear 410 drives the rotation of the ring 411, driving the arc rod 413 to pull the fan plate 414 to open, and under the action of the spring 404, the limit rod 403 will push in the opposite direction to close the fan plate 414, completing the function of quantitative clamping, and will not make the liquid capacity in the extraction liquid chamber 7 too large to affect the dissolution effect;

[0041] The extract in 1 will flow into the fine extraction device 11, and the opening and closing of the solenoid valve 14 will be controlled by the controller 25, so that the raw materials will be transported from the feed port 12 to the fine extraction device 11, and the accelerator 27 will be started to accelerate the dragon plate 18 to quickly merge the raw materials with the extract. At the same time, the accelerated dragon plate 18 will generate centrifugal force to throw part of the dissolved matter onto the inner wall of the fine extraction device 11, and the dissolved matter will be continuously scraped off by the rotating scraper 19, and will participate in high-speed operation and dissolution again. Under the action of the eccentric gear 20, the efficiency of rotation and dissolution is greatly improved.
