Description

Technical Field

[0001] This utility model relates to the field of tailings water treatment technology, specifically a tailings water purification device. Background Technology

[0002] In the ore dressing plant's production process, the whole-sludge cyanide-carbon-in-pulp gold extraction method is the core process. This process mainly utilizes cyanide solution as a leaching agent to form soluble gold complexes through a chemical reaction, which are then recovered through activated carbon adsorption. The production water mainly comes from the clarified water reused from the tailings pond. However, fresh water is required to supplement the process in areas such as gold-loaded carbon extraction, hydraulic conveying of the slurry, desorption electrolysis, plunger pump water seals, and cooling water for the Roots blower. Tailings water purification equipment is a specialized device used to treat tailings slurry from mineral processing plants and recover water resources. It separates solid particles and liquids in tailings using physical or chemical methods, clarifying the water to meet reuse standards. This reduces fresh water consumption, significantly lowers the mineral processing plant's dependence on fresh water, reduces wastewater discharge risks, and improves resource utilization. Existing technology (Chinese patent application CN202421703933.2, filed on 2024-07-18) discloses a thickener. During use, it includes a tank, a main shaft within the tank, a rake frame within the tank, and a vibration mechanism mounted on the rake frame. The main shaft rotates under the drive of the drive mechanism; the rake frame is connected to the main shaft and rotates with it; the vibration mechanism includes a vibration component and a drive component. The vibration component is connected to the rake frame, and the drive component drives the vibration component to vibrate, which in turn drives the rake frame to vibrate. This makes the thickener more efficient and has a lower failure rate. Compared to the traditional method of manually cleaning the tank after rake pressing in a thickener, it saves significant time and money.

[0003] Although existing technologies can improve the purification efficiency of tailings water, there are still some shortcomings in the process. The discharge port structure of the thickener is simple, and when discharging solid waste, it will cause water loss, which will affect the purification efficiency of tailings water. Utility Model Content

[0004] The purpose of this utility model is to provide a tailings water purification device to solve the problem mentioned in the background art that the discharge port structure of the thickener is simple, which causes water loss when discharging solid waste, thus affecting the purification efficiency of tailings water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tailings water purification device, comprising a thickener body, a discharge port located at the bottom center of the thickener body, a first rotating rod located inside the thickener body, a reprocessing chamber fixedly connected to the bottom surface of the discharge port, a second rotating rod located inside the discharge port, and spiral blades, a rotating cleaning assembly, and a filter screen fixedly connected sequentially from top to bottom to the outer wall of the second rotating rod.

[0006] As a preferred technical solution of this application, the first rotating rod is rotatably connected to the thickener body, and the bottom end of the first rotating rod is fixedly connected to the second rotating rod.

[0007] As a preferred technical solution of this application, a solid discharge port is provided in the middle of the bottom of the reprocessing chamber, and a liquid discharge port is provided inside the reprocessing chamber. The liquid discharge port is funnel-shaped, and a liquid discharge pipe is fixedly connected to the bottom surface of the liquid discharge port.

[0008] As a preferred technical solution of this application, the drain pipe is L-shaped and is fixedly connected to the reprocessing chamber.

[0009] As a preferred technical solution of this application, the filter screen is disposed on the top side of the inner wall of the drain port, and the filter screen is rotatably connected to the drain port.

[0010] As a preferred technical solution of this application, the central axis of the filter screen and the drain outlet coincides with the central axis of the second rotating rod.

[0011] As a preferred technical solution of this application, the rotary cleaning assembly includes a fixing ring fixedly connected to the outer wall of the second rotating rod, a cleaning scraper detachably connected to one side of the fixing ring, the cleaning scraper being L-shaped and made of aluminum alloy, and a fixing screw being provided on one side of the fixing ring.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This tailings water purification equipment, through the design of variable-pitch spiral blades, generates gradually increasing pressure when conveying underflow materials, achieving secondary extrusion of the materials. Combined with the centrifugal force of the rotating filter screen, it significantly improves the solid-liquid separation efficiency, realizes further recycling of water resources, reduces the water loss problem caused by traditional simple discharge ports, and improves the water recovery rate. Furthermore, the rotating cleaning component is fixedly connected to the second rotating rod via a fixing ring, and the cleaning scraper is made of L-shaped aluminum alloy. During rotation, it scrapes and cleans the inner wall of the reprocessing chamber, preventing material adhesion and accumulation. The cleaning scraper is detachably connected to the fixing ring via a fixing screw, facilitating maintenance and replacement and improving maintenance efficiency. Specific details are as follows: 1. The motor drives the first rotating rod, the second rotating rod, and the spiral blades to rotate. The spiral blades adopt a variable pitch design, which generates gradually increasing pressure on the material during the conveying process of the underflow material, thereby squeezing the material. The material enters the reprocessing chamber and falls onto the surface of the filter screen. The liquid separated by squeezing is discharged through the filter screen, the drain port, and the drain pipe, which improves the water resource recycling rate. The solid material is trapped above the filter screen. Under the action of centrifugal force, the solid material is thrown to the perimeter of the filter screen and discharged through the solid discharge port, which further separates the solid and liquid of the underflow material, effectively reducing water loss and improving the water recovery rate.

[0013] 2. The rotary cleaning assembly rotates via the second rotary rod, driving the cleaning scraper to perform rotary scraping and cleaning of the inner wall of the reprocessing chamber, removing residues from the inner wall. The cleaning scraper is designed to be detachable, making it easy to disassemble, install, and maintain. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 The present invention provides the following technical solution: a tailings water purification device.

[0018] Example 1: To address the issue that the simple structure of the thickener's discharge port 2 leads to moisture loss during solid waste discharge, thus affecting the purification efficiency of tailings water, please refer to... Figure 2 and Figure 4 The system includes a thickener body 1, a discharge port 2 located at the bottom center of the thickener body 1, a first rotating rod 3 located inside the thickener body 1, a reprocessing chamber 4 fixedly connected to the bottom surface of the discharge port 2, a second rotating rod 5 located inside the discharge port 2, and spiral blades 6, a rotating cleaning assembly 7, and a filter screen 8 fixedly connected sequentially from top to bottom on the outer wall of the second rotating rod 5. Figure 2 As shown, the first rotating rod 3 is rotatably connected to the thickener body 1, and the bottom end of the first rotating rod 3 is fixedly connected to the second rotating rod 5, as shown. Figure 4 As shown, a solid discharge port 9 is provided in the middle of the bottom of the reprocessing chamber 4, and a liquid discharge port 10 is provided inside the reprocessing chamber 4. The liquid discharge port 10 is funnel-shaped, and a liquid discharge pipe 11 is fixedly connected to the bottom surface of the liquid discharge port 10. Figure 4 As shown, the drain pipe 11 is L-shaped, and the drain pipe 11 is fixedly connected to the reprocessing chamber 4, as shown. Figure 4 As shown, the filter screen 8 is located on the top side of the inner wall of the drain port 10, and the filter screen 8 is rotatably connected to the drain port 10, as shown. Figure 4 As shown, the central axis of the filter screen 8 and the drain port 10 coincides with the central axis of the second rotating rod 5.

[0019] During operation, after the thickener body 1 completes concentration, the high-concentration underflow material is discharged from the discharge port 2. At this time, the power source for the first rotating rod 3 is a motor. The motor drives the first rotating rod 3 to rotate, which in turn drives the second rotating rod 5, which is fixedly connected to it, to rotate synchronously. This, in turn, drives the spiral blades 6 to rotate. The spiral blades 6 adopt a variable pitch design, with the pitch gradually decreasing. During the conveying of the underflow material, the pressure on the material gradually increases, thereby squeezing the material. The material enters the reprocessing chamber 4 and falls onto the surface of the filter screen 8. The squeezed and separated liquid is discharged through the filter screen 8, the discharge port 10, and the discharge pipe 11, realizing the recovery of water resources. Solid materials are trapped above the filter screen 8, and the filter screen 8 is fixedly connected to the second rotating rod 5. When the filter screen 8 rotates, it generates centrifugal force. The solid materials are subjected to centrifugal force and are thrown to the sides of the filter screen 8. They are then discharged through the solid discharge port 9 in the middle of the bottom of the reprocessing chamber 4, which further separates the solid and liquid of the underflow material, effectively reducing water loss and improving the water recovery rate. By realizing secondary compression and dynamic filtration of the material during the discharge process, the problem of water loss caused by the traditional simple discharge port 2 is effectively solved. This not only improves the water resource recycling rate and ensures smooth discharge, but also improves the operating efficiency of the entire tailings treatment system.

[0020] Example 2: Figure 6 The technical solution shown includes a rotary cleaning assembly 7, which includes a fixing ring 701 fixedly connected to the outer wall of the second rotating rod 5. A cleaning scraper 702 is detachably connected to one side of the fixing ring 701. The cleaning scraper 702 is L-shaped and made of aluminum alloy. A fixing screw 703 is provided on one side of the fixing ring 701.

[0021] In use, the rotary cleaning assembly 7 is fixedly connected to the second rotating rod 5 via a retaining ring 701. When the second rotating rod 5 rotates, it drives the retaining ring 701 and the cleaning scraper 702 to rotate synchronously, scraping and cleaning the inner wall of the reprocessing chamber 4. This physical contact removes residue from the inner wall, preventing material adhesion and avoiding material accumulation that could reduce equipment efficiency. Furthermore, the cleaning scraper 702 is detachably connected to the retaining ring 701 via a fixing screw 703, allowing for quick assembly and disassembly. This facilitates maintenance and replacement of the cleaning scraper 702, effectively improving maintenance efficiency. The cleaning scraper 702 is made of aluminum alloy, possessing excellent wear resistance and corrosion resistance, making it suitable for high-temperature and high-humidity conditions. The above is the entire working process of the device, and the contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
