[0022] S4: Open the discharge door and discharge the tailings from the reaction tank.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention sets a stirring filter press assembly. When rotating clockwise, the fixed stirring plate and the dynamic stirring plate are fastened by a fastening member, and the synchronous rotation realizes the stirring uniformity function, promotes mass transfer, and completes the decomposition of cyanide. After the decomposition is completed, when rotating counterclockwise, the dynamic stirring plate and the fixed stirring plate are separated by the setting of the movable blocking member baffle. After separation, the fixed stirring plate continues to rotate counterclockwise under the drive of the stirring shaft, so that the tailings liquid after the reaction is completed is filtered under the cooperation of the fixed stirring plate, the dynamic stirring plate and the fixed plate, and the waste liquid is discharged from the filter hole, and the tailings are sandwiched between the fixed stirring plate and the dynamic stirring plate. The waste liquid after separation is discharged from the filter hole, and the tailings are sandwiched between the fixed stirring plate and the dynamic stirring plate. The liquid is discharged from the drain port, and the tailings are discharged from the reaction tank through the discharge door, so that solid-liquid separation is completed. The present invention realizes stirring by setting a stirring and filter pressing assembly and rotating clockwise. The fixed stirring plate and the dynamic stirring plate are not airtight with the inside of the reaction tank, so as to achieve the effect of uniform stirring, improve the decomposition efficiency of cyanide, and make the decomposition more thorough. The filter pressing is realized by rotating counterclockwise, and a sliding plate is connected between the fixed stirring plate and the inner wall of the reaction tank, and a stopper is connected between the dynamic stirring plate and the inner wall of the reaction tank to realize closed filter pressing, and the filter pressing effect is excellent, the gold cyanide tailings are harmlessly treated, the harm to the surrounding environment is avoided, and the remaining resources can be effectively utilized.

[0025] (2) The closing component provided in the present invention ensures the stirring and filtration of the gold cyanide tailings by the engagement and separation between the fixed stirring plate and the dynamic stirring plate, thereby avoiding the escape of the tailings during the filtration, and achieving a good solid-liquid separation effect; specifically, when the fixed stirring plate and the dynamic stirring plate are separated, the wedge block slides out of the second sliding groove and disengages from the cooperation with the sliding block. At this time, under the tension of the plurality of second springs and the third spring, the sliding plate slides out of the first sliding groove and abuts against the inner wall of the reaction tank, so that a cavity is formed between the reaction tank, the fixed stirring plate, the dynamic stirring plate, the stopper, the sliding block and the fixed plate to prevent the tailings from leaking out , the liquid is discharged from the filter holes of the fixed stirring plate, avoiding the tailings from escaping and realizing solid-liquid separation; when the fixed stirring plate and the dynamic stirring plate are buckled, the wedge block slides into the second sliding groove and slides with the sliding block. At this time, the multiple second springs are compressed under the push of the sliding block, pulling the pull rod, driving the third spring to contract, so that the sliding plate is retracted into the first sliding groove, avoiding the sliding plate from abutting against the inner wall of the reaction tank during stirring, causing the stirring plate to be unable to rotate and causing damage to the device, thereby ensuring the stirring and pressure filtration of the gold cyanide tailings and improving the solid-liquid separation effect.

[0039] The feed inlet 110 is used to inject the oxidant. When in use, the gold cyanide tailings raw material can be put into the tank body by opening the tank cover and the fixing plate. The water outlet 120 is used to discharge waste water. The discharge door 140 is hinged on the tank body of the reaction tank 100. When the cyanide tailings are treated, the discharge door is closed to achieve the sealing function of the tank body. After the treatment is completed, the tailings need to be discharged from the tank body, and they can be discharged by opening the discharge door 140.

[0040] The stirring filter press assembly 200 includes a stirring shaft 210 rotatably connected to the reaction tank 100, a motor 260 is fixed on the top of the reaction tank 100, and the output shaft of the motor 260 is fixedly connected to the stirring shaft 210; a fixed stirring plate 220 is fixed on the stirring shaft 210, and a plurality of filter holes are provided on the fixed stirring plate 220; a dynamic stirring plate 230 is rotatably connected to the stirring shaft 210, and the dynamic stirring plate 230 is contactably connected to the movable blocking member 300; the fixed stirring plate 220 is snap-fitted with the end of the dynamic stirring plate 230 away from the stirring shaft 210 by a snap-fitting member 240; a closing component 250 is also connected between the fixed stirring plate 220 and the dynamic stirring plate 230, and the closing component 250 is used for the fixed stirring plate 220 to abut against the inner wall of the reaction tank 100.

[0041] The motor 260 is a forward and reverse motor. One side of the fixed stirring plate 220 is fixedly connected to the stirring shaft 210, and one side of the dynamic stirring plate 230 is rotatably connected to the stirring shaft 210. When the fastening piece 240 is fastened, the dynamic stirring plate 230 rotates together with the fixed stirring plate 220 and the stirring shaft 210. When the fastening piece 240 is not fastened, the dynamic stirring plate 230 will not rotate together with the fixed stirring plate 220 and the stirring shaft 210.

[0042] In this embodiment, the fastening member 240 includes a first fastening strip 241 extending from the front side of the fixed stirring plate 220, and a second fastening strip 246 extending from the rear side of the dynamic stirring plate 230, the bottom surface of the first fastening strip 241 is in contact with the top surface of the second fastening strip 246; the upper end of the second fastening strip 246 is evenly provided with a plurality of mounting grooves 242, the bottom of the mounting groove 242 is installed with a first spring 243, the top of the first spring 243 is fixedly connected with a buckle 245, and the top of the buckle 245 extends out of the mounting groove 242; the lower end of the first fastening strip 241 is evenly provided with a plurality of buckling grooves 247 corresponding to the mounting grooves 242, and the buckles 245 are buckled with the buckling grooves 247.

[0043] During use, when the dynamic stirring plate 230 and the fixed stirring plate 220 need to be buckled, the driving motor 260 drives the fixed stirring plate 220 to rotate clockwise. When the dynamic stirring plate 230 is pushed to rotate to the movable blocking member 300, the fourth spring 350 provided with the movable blocking member 300 has a certain supporting force to prevent the dynamic stirring plate 230 from passing over the stopper 310. At this time, the fixed stirring plate 220 continues to rotate, so that the buckle 245 is squeezed by the first buckling strip 241. During the squeezing, the first spring 243 is compressed, so that the buckle 245 is The first spring 350 is pressed into the locking groove 247 provided on the lower surface of the first locking strip 241 to complete the locking; after the locking is completed, the stirring shaft 210 drives the fixed stirring plate 220 and the dynamic stirring plate 230 to continue to rotate. At this time, the fourth spring 350 is squeezed, and the fixed stirring plate 220 and the dynamic stirring plate 230 can pass the stopper 310 to achieve clockwise rotation to complete the stirring. The fixed stirring plate 220 and the dynamic stirring plate 230 are not sealed from the inside of the reaction tank 100, so as to achieve a uniform stirring effect, thereby improving the decomposition efficiency of cyanide and making the decomposition more thorough.

[0044] After the reaction is completed, when filter pressing is required, the driving motor 260 drives the stirring shaft 210 to rotate counterclockwise. When the stirring shaft 210 rotates counterclockwise to the movable blocking member 300, the blocking member 310 has no obstruction to the fixed stirring plate 220 and can rotate directly through. The side of the dynamic stirring plate 230 close to the inner wall of the reaction tank is blocked by the blocking member 310. Through the setting of the positioning plate 320, the blocking member 310 restricts the dynamic stirring plate 230 from continuing to rotate. At this time, the pressing buckle 245 is forced to slide out of the buckling groove 247 to separate the fixed stirring plate 220 from the dynamic stirring plate 230. Under the counterclockwise rotation and the action of the closing component 250, the tailings are squeezed. During squeezing, the dynamic stirring plate 230 forms a closure between the stopper 310 and the inner wall of the reaction tank 100, so that the waste water is discharged from the filter holes of the fixed stirring plate 220, and the tailings are clamped between the fixed stirring plate 220 and the dynamic stirring plate 230 to complete the filter press. By connecting a sliding plate between the fixed stirring plate 220 and the inner wall of the reaction tank 100, and connecting the stopper 310 between the dynamic stirring plate 230 and the inner wall of the reaction tank 100, a closed filter press is achieved, and the filter press effect is excellent, and the harmless treatment of the gold cyanide tailings is achieved.

[0045] In this embodiment, the closing component 250 includes a first sliding groove 251 opened on the fixed stirring plate 220, and a plurality of second sliding grooves 252 and a pull-rod channel 258, each of the second sliding grooves 252 is connected to the first sliding groove 251 through a corresponding pull-rod channel 258, and the pull-rod channel 258 is J-shaped; a first sliding member 254 is installed in the first sliding groove 251, a second sliding member 253 is installed in the second sliding groove 252, and a pull-rod 255 is installed in the pull-rod channel 258, and the first sliding member 254 and the plurality of second sliding members 253 are connected by the pull-rod 255; a wedge block 221 that slides with the second sliding member 253 is provided on the dynamic stirring plate 230.

[0046] One end of the pull rod 255 is connected to the first sliding member 254 , and the other end of the pull rod is fixedly connected to the second sliding member 253 . When the first sliding member 254 moves in the first sliding groove 251 , the second sliding member 253 moves relatively in the second sliding groove 252 through the transmission of the pull rod 255 .

[0047] In this embodiment, a spring mounting groove 256 is provided at the connection between the plurality of pull rod channels 258 and the first sliding groove 251; the first sliding member 254 includes a third spring 2541 installed in the spring mounting groove 256 and a sliding plate 2542 installed in the first sliding groove 251, the bottom end of the third spring 2541 is fixedly connected to the spring mounting groove 256, the top end of the third spring 2541 is abutted against the sliding plate 2542, and the pull rod 255 is fixedly connected to the bottom end of the sliding plate 2542 after passing through the third spring 2541.

[0048] In this embodiment, the second sliding member 253 includes a second spring 2531 and a sliding block 2532 installed in the second sliding groove 252. The second spring 2531 is located at the end of the sliding block 2532 away from the pull channel 258. The pull bar 255 passes through the sliding block 2532 and is fixedly connected to the top end of the second spring 2531. The bottom end of the second spring 2531 is fixedly connected to the second sliding groove 252. The second sliding block 2532 is provided with an oblique angle for sliding cooperation with the wedge block 221.

[0049] When the fastening piece 240 is fastened, the wedge block 221 and the second sliding block 2532 slide together. At this time, the second sliding block 2532 slides toward the second spring 2531 and squeezes the second spring 2531. The second spring 2531 is compressed, driving the pull bar 255 to slide into the second sliding groove 252. The other end of the pull bar 255 pulls the sliding plate 2542 to slide into the first sliding groove 251 and squeezes the third spring 2541 at the same time, so that the sliding plate 2542 is recovered into the first sliding groove 251. When stirring, the sliding of the sliding plate 2542 is avoided to cause difficulty in stirring the device, thereby avoiding damage to the device, thereby ensuring the stirring effect.

[0050] It should be noted that, in order to ensure that the material does not escape during the filtration, the length of the sliding plate 2542 is consistent with the length of the fixed stirring plate 220 , and the length of the stopper 310 is consistent with the length of the dynamic stirring plate 230 .

[0051] When the buckle 240 is unfastened, the wedge block 221 gradually moves away from the second sliding block 2532 without sliding cooperation. At this time, the second spring 2531 and the third spring 2541 are stretched, and the second sliding block 2532 is pushed toward the pull channel 258 by the tension of the second spring 2531. The tension of the third spring 2541 drives the pull bar 255 to slide into the first sliding groove 251. At the same time, the front end of the sliding plate 2542 is pushed out of the first sliding groove 251, and the end of the sliding plate 2542 located on the outside of the first sliding groove 251 abuts against the inner wall of the reaction tank 100. When the filter press is performed, it can ensure that the tailings will not leak out from the side of the fixed stirring plate 220, resulting in unclean filtration.

[0052] In this embodiment, when the multiple second sliding members 253 slide in cooperation with the wedge block 221, the sliding plate 2542 is retracted into the first sliding groove 251; when the multiple second sliding members 253 do not slide in cooperation with the wedge block 221, the sliding plate 2542 is driven to slide out of the first sliding groove 251 and abut against the inner wall of the reaction tank 100.

[0053] In this embodiment, the movable blocking member 300 includes a block 310 rotatably connected to the inner wall of the reaction tank 100, and a positioning plate 320 for limiting the rotation of the block 310 is fixed on the inner wall of the reaction tank 100 located on one side of the block 310; a plurality of first spring mounting seats 330 are evenly distributed on the block 310, and the first spring mounting seats 330 are located on the side of the block 310 away from the positioning plate 320, and a second spring mounting seat 340 corresponding to the first spring mounting seat 330 is fixed on the inner wall of the reaction tank 100, and a fourth spring 350 is fixedly connected between the first spring mounting seat 330 and the second spring mounting seat 340.

[0054] When stirring clockwise, the fourth spring 350 between the block 310 and the inner wall of the reaction tank 100 is compressed, and the stirring plate can pass through smoothly. When rotating counterclockwise, the block 310 is away from the positioning plate 320 set on one side of the fourth spring 350, so that the block 310 is limited and can prevent the moving stirring plate 230 from passing through, thereby forming a filter press function.

[0055] In this embodiment, a fixed plate 130 is detachably installed in the reaction tank 100, and the bottom surface of the fixed plate 130 is in contact with the top surfaces of the fixed stirring plate 220 and the dynamic stirring plate 230, and the bottom surfaces of the fixed stirring plate 220 and the dynamic stirring plate 230 are in contact with the bottom wall of the reaction tank 100.

[0056] The setting of the fixed plate 130 can prevent the feed liquid from flowing through the top during filtration and causing the material to escape when forming tailings. The specific fixing position of the fixed plate 130 can be achieved by setting a fastener in the reaction tank 100. Through the fastening of the fastener and the fixed plate 130, the fixed plate 130 is sealed and connected to the inner wall of the reaction tank 100, and the fastener can also be unfastened to facilitate feeding and disassembly and cleaning.

[0057] In this embodiment, a scraper is fixed to the bottom of the side away from each other after the dynamic stirring plate 230 and the fixed stirring plate 220 are engaged with each other.

[0058] The scraper can pick up some tailings precipitated on the inner bottom wall of the reaction tank 100 , and can also prevent the tailings from being blocked between the fixed stirring plate 220 and the dynamic stirring plate 230 and the inner bottom wall of the reaction tank 100 .
