Description

Technical Field

[0001] This invention relates to the field of metal recycling technology, and more particularly to a leaching device for zinc-containing dust. Background Technology

[0002] Leaching refers to the process of extracting soluble substances from solids using chemical solvents. It is also known as extraction. The chemical solvent used for leaching is called the leaching agent, the solution obtained after leaching is called the leachate, and the remaining solid is called the residue. The leaching effect is expressed by the leaching rate, which is the percentage of soluble substances in the solid that dissolve into the leachate. In hydrometallurgy, the solids leached are metallurgical intermediate products such as ores, concentrates, roasted sand or matte, flue dust, and anode mud. The leaching of zinc-containing flue dust requires mixing with choline chloride-urea leaching agent liquid and water. It is mostly completed using leaching equipment, which has the advantages of simple operation, stable structure, and good performance.

[0003] The prior art discloses a method and apparatus for leaching zinc-containing dust from a steel plant, with publication number CN113234934B. In the above technical solution, the mixing of zinc-containing dust, choline chloride-urea leaching agent liquid, and water requires stirring with rotating stirring blades. However, there is a gap between the stirring blades and the storage space, so some substances cannot be fully mixed. Secondly, the mixed leaching solution and leaching residue need to be filtered through a filter screen. When it is necessary to clean the leaching residue on the filter screen, the filtration operation must be stopped. Finally, the zinc-containing dust needs to be stirred and mixed inside the mixing space, but the mixing space has no airtightness detection structure. When there is a leak in the mixing space, the zinc-containing dust will leak.

[0004] To address these shortcomings, we propose a zinc-containing fume leaching device. Summary of the Invention

[0005] The purpose of this invention is to provide a leaching device for zinc-containing dust to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A leaching device for zinc-containing dust includes a mounting plate. A rotating cylinder is passed through the end face of the mounting plate via a bearing. A storage tank, a dust chamber, a reagent tank, a filter square tube, and an annular electromagnet are mounted on the end face of the mounting plate. A four-way pipe passes through the lower part of the storage tank, dust chamber, and reagent tank, with one end of the four-way pipe passing through the end face of the rotating cylinder via a bearing. A temperature sensor and an air inlet pipe are fixedly inserted through the side wall of one end of the four-way pipe. One end of the temperature sensor is inserted into the interior of the rotating cylinder. An electrical control box is mounted on one side of the mounting plate, and a controller and a synchronization controller are installed inside the electrical control box. Multiple sets of connecting pipes and a liquid outlet pipe are fixedly passed through the outer wall of the rotating cylinder. The distal ends of the multiple sets of connecting pipes are all fixedly sleeved with storage tanks. The storage tanks are equipped with sliding rods that slide through their opposite sides. Piston plates are mounted on the opposing ends of the sliding rods. Limiting plates are mounted on the opposite ends of the sliding rods. Telescopic springs are fitted onto the side walls of the sliding rods. A right-angle bracket is mounted on the rear end of the mounting plate, and a drive motor is mounted on the rear end of the right-angle bracket. A small gear is fitted onto the output end of the drive motor. A shaft tube passes through the rear end of the rotating cylinder via a bearing, and an electric heating rod passes through the inside of the shaft tube via a bearing. The rear end of the electric heating rod passes through the right-angle bracket. An external toothed ring is fixedly fitted onto the side wall of the rotating cylinder. Multiple sets of stirring blades are mounted on the side wall of the shaft tube. A ventilated mesh is provided on the opposite sides of the storage tanks.

[0008] The pinion meshes with the external gear ring.

[0009] A control valve is provided on the side wall of the outlet pipe.

[0010] The vertical cross-sectional diameter of the temperature sensor is smaller than the internal diameter of the four-way tube.

[0011] A collection box is installed at the lower part of the filter square tube, and a water pump is installed on the outer wall of the collection box. The output end of the water pump is connected to a suction pipe, one end of which is inserted into the inside of the collection box. Two sets of filter screens are penetrated through the bottom surface of the filter square tube. Fixing plates are installed on both sides of the mounting plate, and forward and reverse motors are installed on the rear end faces of both sets of fixing plates. The output ends of both sets of forward and reverse motors are fitted with winding reels, and pull ropes are wound around the side walls of both sets of winding reels. Three sets of piston blocks are slidably installed inside the filter square tube, and connecting rods are installed between adjacent sets of piston blocks. One end of each set of pull ropes is fixedly connected to the two sets of piston blocks on both sides. A feed hopper is fixedly inserted through the upper part of the filter square tube. The two sets of forward and reverse motors are electrically connected to a synchronous controller via wires. The water pump and the synchronous controller are electrically connected to the controller via wires.

[0012] An air pump is mounted on the end face of the mounting plate, and a three-way pipe is snapped into the input end of the air pump. One end of the inflation pipe is snapped into the output end of the air pump. Mounting boxes are sleeved on both sides of the three-way pipe, and a servo motor is mounted on the other side of the mounting box. A main gear is sleeved on the output end of the servo motor. Two sets of rotating tubes pass through the other side of the mounting box via bearings, and a filter basket is mounted on one end of each set of rotating tubes. A driven gear is sleeved on the side wall of the other end of each set of rotating tubes. The servo motor is electrically connected to the controller via wires.

[0013] The main gear meshes with the two sets of driven gears.

[0014] All of the aforementioned limiting plates are made of iron.

[0015] The other three ends of the three-way pipe are equipped with electronic metering valves. The upper part of the liquid storage tank, dust box and medicine box are all fixedly connected by inlet pipes, and the side walls of the three sets of inlet pipes are equipped with solenoid valves. The controller is electrically connected to the three sets of solenoid valves, the three sets of electronic metering valves, the annular electromagnet, the water pump, the temperature sensor, the drive motor and the electric heating rod through wires.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1) This invention employs a rotating cylinder and a storage tank. In actual use of the zinc-containing fume leaching device, the outer wall of the collection box is first penetrated by the external anode and external cathode. Then, the controller opens and closes three sets of electronic metering valves, simultaneously energizing the annular electromagnet, water pump, temperature sensor, drive motor, and electric heating rod. Water, choline chloride-urea leaching agent liquid, and zinc-containing fume can enter the interior of the rotating cylinder through the four-way pipe. When the amount entering reaches the preset value of the three sets of electronic metering valves, a signal is sent to the controller, which closes the three sets of electronic metering valves. At the same time, the output of the drive motor drives the pinion to rotate. Since the pinion meshes with the external gear ring, the rotating pinion drives the external gear ring to rotate, which in turn drives the rotating cylinder to rotate. When the annular electromagnet is energized, multiple sets of limiting plates are directed toward the annular electromagnet. The rotating drum is equipped with multiple limit plates that can move multiple piston plates away from each other via multiple moving rods. During this process, the piston plates can squeeze multiple telescopic springs, and the mixture inside the rotating drum will sequentially enter the interior of multiple storage tanks through multiple connecting pipes. The electric heating rod can heat the mixture through the shaft tube, and multiple stirring blades can stir the mixture. When one end of the liquid outlet pipe is directly above the feed hopper, the annular electromagnet is de-energized, and the multiple telescopic springs can push the multiple piston plates, which can push the mixture inside the multiple storage tanks back into the rotating drum. The control valve is opened and closed, and the mixture inside the rotating drum can enter the interior of the feed hopper through the liquid outlet pipe. Through the rotating drum and storage tanks, the zinc-containing dust, choline chloride-urea leaching agent liquid, and water can be fully mixed, improving the mixing efficiency of the zinc-containing dust leaching device.

[0018] 2) This invention uses a filter square tube. As described above, the mixed leachate and leaching residue can fall into the interior of the filter square tube through the feed hopper. Using a controller, the output ends of two sets of forward and reverse motors are rotated synchronously through a synchronous controller. The two sets of synchronously rotating winding discs can move three sets of piston blocks to the left or right. During the left and right movement of the three sets of piston plates, the leachate can enter the interior of the collection box through two sets of filter screens. At the same time, the three sets of piston plates can push out the leaching residue inside the filter square tube. Using the controller again, the external anode and external cathode are energized to perform electrolysis on the zinc-containing leachate that has entered the collection box. When the water pump is working, the zinc-containing electrolytic solution can be extracted through the suction pipe. Through the filter square tube, the filtered leaching residue can be cleaned without stopping the filtration work, which brings convenience to the cleaning of leaching residue in the zinc-containing fume leaching device.

[0019] 3) This invention employs an air-filling pipe. Before actually using the zinc-containing leaching device, the controller first activates the air pump and servo motor. Air enters the installation box through two sets of filter baskets. Air inside the installation box then enters the four-way pipe through a three-way pipe and an air-filling pipe. Finally, air fills the rotating drum. The output of the servo motor drives the main gear to rotate, which in turn drives two sets of driven gears. These driven gears rotate through two sets of rotating pipes, causing the two sets of filter baskets to rotate. Using centrifugal force, the adsorbent on the surface of the two sets of filter baskets is thrown off, and the contents of the rotating drum are released into the air. Air can enter the interior of multiple storage tanks through multiple sets of connecting pipes. When multiple limit plates contact the inner wall of the annular electromagnet, the air pump stops. When there is a leak inside the rotating cylinder, multiple telescopic springs, under their own elastic force, can push multiple piston plates to push the air inside the multiple storage tanks back into the rotating cylinder through multiple sets of connecting pipes. Operators can determine whether there is a leak in the rotating cylinder by observing the position of the multiple limit plates. Through the air filling pipe, an airtightness detection structure is provided to detect whether there is a leak in the mixing space, thus ensuring the safe use of the zinc-containing dust leaching device.

The controller is electrically connected to the three solenoid valves 7, the three electronic metering valves, the annular electromagnet 10, the water pump 13, the temperature sensor 24, the drive motor 26, and the electric heating rod 30 via wires.

[0048] In this implementation scheme: the controller control circuit can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0049] Working Principle: In actual use of the zinc-containing fume leaching device, the outer wall of the collection box 11 is first connected to the external anode and external cathode. Then, the controller is used to open and close the three sets of electronic metering valves. At the same time, the annular electromagnet 10, water pump 13, temperature sensor 24, drive motor 26, and electric heating rod 30 are energized. Water, choline chloride-urea leaching agent liquid, and zinc-containing fume can enter the interior of the rotating cylinder 2 through the four-way pipe 8. When the amount entering reaches the preset value of the three sets of electronic metering valves, a signal is sent to the controller, which closes the three sets of electronic metering valves. At the same time, the output end of the drive motor 26 can drive the pinion 27 to rotate. Since the pinion 27 meshes with the external gear ring 28, the rotating pinion 27 can push the external gear ring 28 to rotate. 28 can drive the rotating drum 2 to rotate. When the annular electromagnet 10 is energized, multiple sets of limiting plates 19 can move toward the annular electromagnet 10. The multiple sets of limiting plates 19 can move multiple sets of piston plates 18 away from each other through multiple sets of moving rods 17. During this process, the multiple sets of piston plates 18 can squeeze multiple sets of telescopic springs 20 respectively. The mixture inside the rotating drum 2 will enter the interior of multiple sets of storage tanks 22 through multiple sets of connecting pipes 16 in sequence. The electric heating rod 30 can heat the mixture through the shaft tube 29. Multiple sets of stirring blades 31 can stir the mixture. When one end of the liquid outlet pipe 23 is directly above the feed hopper 12, the annular electromagnet 10 is de-energized. The multiple sets of telescopic springs 20 can push the multiple sets of piston plates 18 respectively. The multiple sets of piston plates 18 can push the mixture inside the multiple sets of storage tanks 22 back into the rotating drum 2. The control valve is opened and closed, and the mixture inside the rotating drum 2 can enter the feed hopper 12 through the liquid outlet pipe 23. Through the rotating drum 2 and storage tank 22, the zinc-containing dust, choline chloride-urea leaching agent liquid, and water can be fully mixed, improving the mixing efficiency of the zinc-containing dust leaching device. Simultaneously, according to the above operation, the mixed leaching liquid and leaching residue can fall into the filter square tube 9 through the feed hopper 12. Using the controller, the output ends of the two sets of forward and reverse motors 33 are rotated synchronously through the synchronous controller. The two sets of synchronously rotating winding discs 34 can move the three sets of piston blocks 45 to the left or right. During the left and right movement of the three sets of piston plates 18, the leaching liquid can enter the collection box 11 through the two sets of filter screens 35. At the same time, the three sets of piston plates... The leaching residue inside the filter square tube 9 can be pushed out by the controller. The external anode and cathode are then energized again to electrolyze the zinc-containing leaching solution entering the collection box 11. When the water pump 13 is working, the zinc-containing electrolytic solution can be extracted through the suction pipe 14. The filtered leaching residue can be cleaned through the filter square tube 9 without stopping the filtration process, facilitating the cleaning of leaching residue in the zinc-containing fume leaching device. Simultaneously, before actually using the zinc-containing fume leaching device, the air pump 36 and servo motor 39 are activated by the controller. Air enters the installation box 38 through two sets of filter baskets 42. The air inside the installation box 38 enters the four-way pipe 8 through the three-way pipe 37 and the air filling pipe 15, ultimately filling the rotating drum 2.The output of the servo motor 39 drives the main gear 40 to rotate. The rotating main gear 40 drives two sets of driven gears 43 to rotate. The two sets of driven gears 43 rotate through two sets of rotating tubes 41, causing two sets of filter baskets 42 to rotate. Using centrifugal force, the adsorbed material on the surface of the two sets of filter baskets 42 is thrown off. The air inside the rotating cylinder 2 enters the interior of multiple storage tanks 22 through multiple sets of connecting pipes 16. When multiple limit plates 19 contact the inner wall of the annular electromagnet 10, the air pump 36 stops. When there is a leak inside the rotating cylinder 2, multiple sets of telescopic springs 20, under their own elastic force, push multiple sets of piston plates 18 to push the air inside the multiple storage tanks 22 back into the rotating cylinder 2 through multiple sets of connecting pipes 16. The operator can determine whether there is a leak in the rotating cylinder 2 by observing the position of the multiple limit plates 19. The air filling pipe 15 has an airtightness detection structure, which can detect whether there is a leak in the mixing space, thus ensuring the safe use of the zinc-containing dust leaching device.
