[0045] As a more detailed embodiment of the present embodiment, the inner throwing filter cylinder 310 is integrally provided with an upper cover ring 311 on the upper part, and a guide hopper 331 is inserted on the upper cover ring 311. The upper cover ring 311 can rotate around the guide hopper 331. The guide hopper 331 is sleeved and fixed with an auxiliary ring 330 outside. The auxiliary ring 330 is assembled on the upper part of the pretreatment tank 300. An inner sleeve shaft 312 is integrally arranged in the inner throwing filter cylinder 310. A lower insertion shaft 322 is assembled and inserted in the inner sleeve shaft 312. The top end of the lower insertion shaft 322 is fixed to the bottom of the hanging shaft rod 320. The bottom of the lower insertion shaft 322 is tightly assembled and fastened through a nut. An inner insertion groove 323 corresponding to the lower insertion shaft 322 is formed in the inner sleeve shaft 312. Through this design, the inner throwing filter cylinder 310 is conveniently hoisted and disassembled, and the liquid inlet is also conveniently guided.

[0046] Working principle: when the waste liquid needs to be treated and reused in the ore dressing plant, the inlet pipe 110 is connected to the waste liquid pump, the outlet pipe 120 is connected to the collection and reuse device, and the filling pipe 204 is connected to the reagent filling pipe. The waste liquid is pumped into the pretreatment tank 300 by the waste liquid pump. After the internal pretreatment and filtration, the electric valve one 130 is opened to make the waste liquid enter the internal reaction of the secondary tank 200 to produce flocculent precipitate. After the internal filtration and precipitation in the secondary tank 200, the electric valve two 140 is opened to discharge the waste liquid through the outlet pipe 120 for subsequent reuse or other process treatment.

[0047] When operating, the servo motor 510 is driven to rotate, driving the transmission box 520 and the transmission wheel one 530 to rotate, and driving the transmission vertical shaft 540 to rotate under the transmission of the transmission bevel gear 521 and the driven bevel gear 523, thereby driving the hanging shaft rod 320 to rotate under the cooperation of the transmission wheel two 550, the belt two 551 and the driven wheel two 552. The hanging shaft rod 320 rotates to drive the inner throwing filter cylinder 310 to rotate under the cooperation of the lower insertion shaft 322. After the waste liquid enters, it is guided by the auxiliary ring 330 and the flow guide hopper 331 to smoothly enter the internal throwing filter cylinder 310, so that the internal throwing filter cylinder 310 rotates to throw out the liquid in the waste liquid, thereby leaving the solid foreign matter inside, facilitating rapid separation. Subsequently, the electric valve one 130 is opened to enter the internal reaction of the secondary tank 200. After the corresponding reagent is filled through the filling pipe 204, the liquid in the secondary tank 200 reacts with the reagent to produce flocculent precipitate. During the reaction, the transmission wheel one 530 rotates to drive the rotating shaft rod 222 to rotate under the cooperation of the belt one 531 and the driven wheel one 532, thereby driving the stirring rod 221 and the side turntable 220 to rotate to stir the internal reaction of the secondary tank 200, accelerate the mixing and reaction rate, and produce the precipitate. The collection drawer 210 and the filter bottom plate 211 collect the precipitate, which is convenient for discharge through the opening of the electric valve two 140, and facilitates filtration. When the waste liquid is filtered and discharged, the stirring rod 221 rotates to move the push rod 213, which moves the inner scraper 212 under the cooperation of the inner sliding rod 230 and the inner spring 231 to facilitate horizontal sliding and elastic recovery. The continuous rotation of the stirring rod 221 continuously pushes the push rod 213 and the elastic recovery, which facilitates periodic scraping, and facilitates the precipitation of the precipitate on the surface of the filter bottom plate 211 to prevent the precipitate from being covered and not moving to cause blockage, thereby facilitating the discharge of the liquid.

[0048] When operating, during the treatment of waste liquid, the opening and closing of the electric valve one 130 and the electric valve two 140 can be controlled by the corresponding relay and other control modules according to the reaction rate and experience to make the subsequent operation more convenient. According to the treatment process and the different substances contained in the waste liquid, the secondary tank 200 can be selected to be stacked. The corresponding number of secondary tanks 200 are combined under the cooperation of the support column 104, the lower support plate 101 and the middle support plate 102 to gradually remove the internal foreign matter and heavy metal substances.

[0049] In operation, after a period of time of processing waste liquid, the inner filter cylinder 310 can be removed by disassembling the middle front cylinder wall 305, then unscrewing and removing the nut at the bottom of the lower insertion shaft 322, facilitating the removal of the inner filter cylinder 310, facilitating the pouring and cleaning of foreign matter inside the inner filter cylinder 310, thereby facilitating the cleaning of the inside of the pretreatment tank 300; the manual buckle 241 can also be pried open and the buckle pull tongue 242 can be separated, thereby taking out the inner baffle plate 250 and the side baffle plate 240, then pulling the handle 252, facilitating the extraction of the collection drawer 210, during extraction, the push rod 213 can be removed by cooperating with the lower insertion rod 214 and the lower insertion groove 215, facilitating the extraction operation, so that the collection drawer 210 and the filter bottom plate 211 cooperate to facilitate the removal of the collected precipitate, also facilitating cleaning, making use more convenient.

[0050] The above is only a preferred embodiment of the present application, and does not limit the present application in any form; any person skilled in the art can easily implement the present application according to the drawings and the above description; however, any equivalent changes, modifications and evolution made by those skilled in the art within the scope of the technical solutions of the present application, using the disclosed technical content, are equivalent embodiments of the present application; at the same time, any equivalent changes, modifications and evolution of the above embodiments according to the essence of the present application are still within the protection scope of the technical solutions of the present application.
