[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: an acid treatment device for cyanide tailings from gold smelting, comprising a support platform 1, a reaction tank 2 installed through the middle of the support platform 1, a cover 4 fixedly installed on the upper part of the reaction tank 2, a discharge pipe 5 connected to the bottom of the reaction tank 2, and a connecting assembly 3 located on one side of the support platform 1. The connecting assembly 3 includes a stirring mechanism 31 installed inside the reaction tank 2, a disassembly and assembly mechanism 32 located at the bottom of the reaction tank 2, an electrically controlled valve located at one end of the discharge pipe 5 near the reaction tank 2, and a feed pipe connected to the upper part of the cover 4. The stirring mechanism 31 includes a motor 311 fixedly installed on the upper part of the cover 4 via a base, and a first rotating shaft 312 fixedly connected to the output end of the motor 311. The outer wall of the first rotating shaft 312 is divided into... A first conical tooth 313 and a transmission tooth 314 are fixedly connected. A crushing roller 315 is fixedly connected to the outer wall of the first rotating shaft 312. A crushing box 316 is fixedly installed on the upper part of the box cover 4. A second rotating shaft 317 is rotatably connected to the middle of the box cover 4 through a bearing. A second conical tooth 318 is fixedly connected to the top of the second rotating shaft 317. A first connecting rod 319 and a second connecting rod 3113 are fixedly connected to the outer wall of the second rotating shaft 317. A scraper 3110 is fixedly connected to the end of the first connecting rod 319 away from the second rotating shaft 317. A stirring rod 3111 is fixedly connected to one side of the scraper 3110. A conveying cylinder 3112 is fixedly connected to the end of the stirring rod 3111 away from the scraper 3110. A conveying blade 3114 is fixedly connected to the outer wall of the second rotating shaft 317.

[0030] In this embodiment, the first rotating shaft 312 is rotatably connected to the crushing box 316 via a bearing. The crushing roller 315 is located inside the crushing box 316. Through the cooperation of the motor 311, the first rotating shaft 312, the first conical tooth 313, the transmission tooth 314, the crushing roller 315, the crushing box 316, the second rotating shaft 317, the second conical tooth 318, the first connecting rod 319, the scraper 3110, the stirring rod 3111, the conveying cylinder 3112, the second connecting rod 3113, and the conveying blade 3114, the large particles of cyanide tailings added to the reaction box 2 can be crushed, which makes subsequent stirring operations easier. It can also convey the material at the bottom of the reaction box 2 upwards, thereby making the material more thoroughly stirred and improving the reaction effect.

[0031] Furthermore, a feed hopper is connected to the top of the crushing box 316, and the bottom of the crushing box 316 is connected to the box cover 4.

[0032] Furthermore, the first conical tooth 313 is engaged with the second conical tooth 318, and the end of the second connecting rod 3113 away from the second rotating shaft 317 is fixedly connected to the scraper rod 3110.

[0033] Furthermore, there are two transmission teeth 314, two crushing rollers 315, and two first rotating shafts 312, and the two transmission teeth 314 are meshed together.

[0034] In operation, the device first manually feeds material into the crushing chamber 316 from the feed hopper. Then, the motor 311 drives the first rotating shaft 312 to rotate. The meshing of two transmission teeth 314 causes the crushing rollers 315, fixedly connected to the outer wall of the first rotating shaft 312, to rotate in opposite directions. This crushes the large particles of cyanide tailings added to the crushing chamber 316. The crushed material falls into the reaction chamber 2. Then, the meshing of the first conical teeth 313 and the second conical teeth 318 causes the second rotating shaft 317 to drive the first connecting rod 319 to rotate, thus allowing the rollers 315, fixedly connected to the first rotating shaft 312, to rotate. The scraper 3110 at one end of the connecting rod 319 rotates synchronously. Since the scraper 3110 is fixedly connected to the conveying cylinder 3112 through the stirring rod 3111, the stirring rod 3111 and the conveying cylinder 3112 can rotate synchronously, thereby stirring the material in the reaction tank 2. Under the action of the scraper 3110, the material can be prevented from sticking to the inner wall of the reaction tank 2. Furthermore, when the second rotating shaft 317 rotates, the conveying blades 3114 fixedly connected to the outer wall of the second rotating shaft 317 can rotate synchronously, thereby conveying the material at the bottom of the reaction tank 2 upward, thus making the material more thoroughly stirred and the processing effect better.

[0035] Example 2

[0036] Based on Example 1, a preferred embodiment of the cyanide tailings acid treatment device based on gold smelting provided by this utility model is as follows: Figures 1 to 4 As shown: The disassembly and assembly mechanism 32 includes a dredging port 3210 at the front of the discharge pipe 5. The inner wall of the dredging port 3210 is provided with an installation groove 321. A sealing plate 322 is inserted into the installation groove 321. A slot 323 is provided on one side of the sealing plate 322. A sealing ring 324 is fixedly connected to the inner wall of the dredging port 3210. A movable groove 325 is provided inside the discharge pipe 5. A movable block 326 is slidably connected to the inner wall of the movable groove 325. A sloping block 327 is fixedly connected to one side of the movable block 326. A first spring 328 is fixedly connected to the inner wall of the movable groove 325. A movable hole 329 is provided on the outer side of the inner wall of the movable groove 325.

[0037] In this embodiment, the inclined plate 327 is movably inserted through the movable groove 325. The inclined plate 327 is engaged with the groove 323. Through the cooperation of the mounting groove 321, sealing plate 322, groove 323, sealing ring 324, movable groove 325, movable block 326, inclined plate 327, first spring 328, movable hole 329, and unblocking port 3210, the sealing plate 322 can be disassembled. This facilitates manual unblocking of the discharge pipe 5 through the unblocking port 3210, preventing material from clogging the discharge pipe 5 and affecting subsequent discharge operations.

[0038] Furthermore, one end of the first spring 328 is fixedly connected to the movable block 326, and the unblocking port 3210 is set in the gap between the sealing plate 322 and the unblocking port 3210.

[0039] Furthermore, a pull rod is movably connected to the inner wall of the movable hole 329, and the outer side of the movable block 326 is fixedly connected to the pull rod.

[0040] When cleaning is required inside the discharge pipe 5, firstly, manually pull the lever to move the movable block 326, thereby separating the inclined locking block 327 fixedly connected to one side of the movable block 326 from the locking groove 323. Then, the sealing plate 322 can be manually pulled out, facilitating manual cleaning of the inside of the discharge pipe 5 through the unblocking port 3210. This prevents material from clogging inside the discharge pipe 5 and affecting subsequent discharge operations. Furthermore, when installing the sealing plate 322, simply insert the sealing plate 322 manually into the installation groove 321. When the sealing plate 322 enters the mounting groove 321, the inclined plate 327 can be pressed into the movable groove 325 because its outer side is inclined. At this time, the first spring 328 is compressed. Then, when the sealing plate 322 is fully engaged with the mounting groove 321, the movable block 326 can move the inclined plate 327 outward under the action of the elastic force of the first spring 328, so that the inclined plate 327 can engage with the groove 323, thereby fixing the sealing plate 322 in the mounting groove 321. The installation operation is completed, and the operation is simple and convenient.
