Description

Technical Field

[0001] The invention relates to the technical field of copper metal recovery, and in particular to a copper metal recovery device and method for molybdenum concentrate tailings slurry. Background Art

[0002] At present, the products of the sorting operation in mineral processing that have a low content of useful target components and cannot be used for production are called tailings. As the equipment runs and discharges, a large amount of slurry will be produced in the tailings. There is also a large amount of copper metal in these slurries, so they need to be recovered to reduce waste. Although the existing slurry recovery equipment can effectively filter and recover, it cannot be easily cleaned as a whole. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN220899763U, a copper tailings metal recovery and filtering device, includes a base, a working box is arranged on the top of the base, two water storage tanks are arranged on the side of the working box, the tops of the two water storage tanks are arranged with water inlets, and one side of the working box is also provided with a water outlet, a closed cover plate is arranged on the top of the working box, and the top of the closed cover plate is also provided with a feed port, two protrusions are arranged at one end of the closed cover plate, and shafts are arranged on the sides of the two protrusions, and the shafts are adapted to be installed between the through holes opened on the top of the working box. The utility model provides a rotating structure on the top of the closed cover plate, and the rotating structure drives the stirring rod to rotate through the first motor drive, thereby driving the stirring block fixedly installed on the outer wall of the stirring rod to rotate inside the filter barrel, thereby fully stirring the tailings metal placed inside the filter barrel, so that impurities on the tailings metal are separated, thereby improving the recovery rate of the tailings metal.

[0004] Although the equipment in the above documents can filter the slurry, it still has obvious defects in actual use, such as:

[0005] The equipment only uses the nozzle to impact the slurry inside to filter it. Although it can stir, most of the impact force of the water flow will be blocked by the mesh tube, and the force on the internal slurry is small. This method leads to low filtration efficiency, and the continuous impact also wastes water resources. In addition, most of the equipment for filtering slurry is medium and large equipment, and it needs to be manually disassembled by the staff for flushing and cleaning, which undoubtedly increases the workload and difficulty.

[0006] Therefore, a copper metal recovery device for molybdenum concentrate tailings slurry capable of improving filtration efficiency is now designed to solve such defects. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a copper metal recovery device and method for molybdenum concentrate tailings slurry, which solves the problems of low efficiency and inconvenience in use of existing copper metal recovery equipment.

[0010] Preferably, the top of the base plate bracket is fixedly connected to a motor via a bracket, the output shaft of the motor is fixedly connected to a rotating rod via a coupling, the top end of the rotating rod penetrates the water storage filter box and extends to the interior of the water storage filter box, one end of the rotating rod extending to the interior of the water storage filter box is fixedly connected to a polygonal column used in conjunction with the polygonal inner cylinder, and the left side of the water storage filter box is fixedly connected to a water injection pipe via an opening.

[0011] Preferably, a screen slide frame is sleeved on the surface of the rotating rod, and the front and rear parts on both sides of the bottom of the water storage filter box are fixedly connected with guide vertical rods through fixing blocks, and the bottom ends of the guide vertical rods penetrate the screen slide frame and extend to the lower part of the screen slide frame, and a first spring is sleeved on the surface of the guide vertical rod and located between the screen slide frame and the water storage filter box.

[0012] Preferably, the bottom of the screening slide frame is fixedly connected to a sloped stop block via a fixed block, and a plurality of sloped stop blocks are arranged in a ring shape, the upper part of the rotating rod surface is fixedly connected to a round stop rod used in conjunction with the sloped stop block via a fixed block, and both sides of the bottom of the inner cavity of the water storage filter box are fixedly connected to discharge vertical pipes used in conjunction with the screening slide frame via openings.

[0013] Preferably, an annular tooth groove is provided on the upper part of the surface of the filter screen cylinder, and rectangular pressure frames are slidably installed on the upper parts of both sides of the inner cavity of the water storage filter box through the openings, and a second spring is sleeved on the surface of the rectangular pressure frame, and the opposite sides of the two rectangular pressure frames are fixedly connected with arc-shaped tooth plates used in conjunction with the annular tooth groove.

[0014] Preferably, both sides of the upper top plate frame are fixedly connected with side tie rods via fixed plates, the bottom ends of the side tie rods penetrate the water storage filter box and extend to the interior of the water storage filter box, one end of the side tie rod extending to the interior of the water storage filter box is fixedly connected with a sealing plug used in conjunction with a discharge vertical pipe via a fixed plate, and one side of the sealing plug is fixedly connected with an inclined pressure seat used in conjunction with a rectangular pressure frame via a fixed plate.

[0015] The present invention also discloses a method for recovering copper metal from molybdenum concentrate tailings slurry, which specifically comprises the following steps:

[0016] S1. Before use, first put the tailings slurry into the filter cylinder, and then use the water injection pipe to inject water into the water storage filter box. After completing the preparation process, go to step S2;

[0017] S2, at this time, the motor is started to drive the rotating rod to rotate. Since the polygonal column and the polygonal inner cylinder are connected, the polygonal inner cylinder and the lifting circular plate are rotated. When the lifting circular plate rotates, it drives the stirring blade to rotate to stir and dilute the slurry inside the filter cylinder. At the same time, the copper metal inside the slurry will be scattered to the bottom of the inner cavity of the water storage filter box due to its weight as it is stirred by the stirring blade. When the rotating rod rotates, the round resistance rod will continuously squeeze a number of inclined resistance blocks. When the inclined resistance blocks are squeezed, the entire screen slide frame will continuously vibrate up and down under the limit of the guide vertical rod through the elastic force of the first spring. After the slurry inside the filter cylinder is stirred, go to step S3;

[0018] S3. After the mixing is completed, the staff starts the cylinder and uses the upper top plate frame to pull the vertical rotating rod and the side pulling rod up. As the vertical rotating rod pulls up the lifting circular plate and the polygonal inner cylinder, the polygonal inner cylinder is pulled out from the inner side of the docking circular mouth and the polygonal inner cylinder is separated from the polygonal column at the same time. At this time, the vertical rotating rod and the mixing blades no longer rotate, and at the same time the sealing plug is pulled out from the inner side of the discharge vertical pipe, so that the turbid liquid inside the water storage filter box is discharged through the discharge vertical pipe and falls on the top of the screen slide frame. At this time, the shaking screen slide frame and the flowing turbid liquid cause the copper metal to be left on the top of the screen slide frame, and the lifting circular plate continues to rise until it rises to the top of the filter screen cylinder. At this time, the impurities inside the lifting circular plate are located outside, which is convenient for the staff to clean it. When the sealing plugs on both sides rise to the top, the inclined pressure seat squeezes the rectangular pressure frame, so that the arc-shaped tooth plates on both sides retract and separate from the annular tooth grooves. At this time, the filter screen cylinder is loose and can be taken out from the top of the water storage filter box for maintenance.

[0019] Beneficial Effects

[0020] The present invention provides a copper metal recovery device and method for molybdenum concentrate tailings slurry. Compared with the existing technology, it has the following beneficial effects:

[0021] (1) The copper metal recovery device and method for molybdenum concentrate tailings slurry are provided with a filter screen cylinder inside a water storage filter box, and are used in combination with a stirring blade and a sealing plug. The arrangement of these structures can seal the water stored in the water storage filter box in advance, and then the copper metal is dispersed in the water storage filter box by stirring with the stirring blade. This is not only highly efficient but also does not cause a large amount of water waste. After the subsequent lifting circular plate is raised, the water is discharged by a discharge vertical pipe, so that the shaking screen slide frame and the water flow leave the copper metal on the top of the screen slide frame, thereby facilitating collection by the staff.

[0022] (2) The copper metal recovery device and method of molybdenum concentrate tailings slurry are provided with a lifting circular plate inside the filter cylinder, and a polygonal inner cylinder used in conjunction with the polygonal column is installed at the bottom of the lifting circular plate, and is used in conjunction with an inclined pressure seat and an arc-shaped tooth plate. The arrangement of these structures can pull the lifting circular plate up after stirring to push out the residue left inside the filter cylinder for easy cleaning. At the same time, the inclined pressure seat can squeeze the second spring to separate the arc-shaped tooth plate from the annular tooth groove, unlock the filter cylinder, and facilitate the staff to take it out for maintenance. The arc-shaped tooth plate can also be used to position the filter cylinder during operation, thereby ensuring stability during operation and satisfying current use.

[0023] (3) The copper metal recovery device and method for molybdenum concentrate tailings slurry is characterized by installing a screen slide frame at the bottom of a water storage filter box using a guide vertical rod, and using it in conjunction with an inclined support block and a round support rod. The arrangement of these structures can discharge water after the sealing plug rises, and the round support rod squeezes the inclined support block to cause the screen slide frame to vibrate, allowing the copper metal to fall on the top of the screen slide frame due to its own weight, making it self-contained and convenient for staff to collect, without the need for transportation between equipment, and also reducing costs.

[0036] S1. Before use, first put the tailings slurry into the filter screen cylinder 3, and then use the water injection pipe 14 to inject water into the water storage filter box 2. After completing the preparation process, go to step S2;

[0037] S2, at this time, the motor 11 is started to drive the rotating rod 12 to rotate.
