[0001] The invention relates to the technical field of stirring barrels, in particular to a mining dehydration stirring barrel and a use method thereof. Background Art

[0002] With the continuous expansion of the scale of ore mining, various types of ores are mined. These ores need to be dehydrated during the processing to meet the requirements of subsequent production processes. Dehydration mixing barrels are one of the indispensable equipment in mining production. With the increasing scarcity of mineral resources and the increase in mining difficulty, mining companies have higher and higher requirements for improving resource recovery and utilization rates. Therefore, new types of mining dehydration mixing barrels are needed to solve the above problems.

[0003] However, during the use of the existing mining dehydration mixing barrel, the stirring paddle is fixed in position and is not easy to adjust in time, so that the ore is not easy to be fully stirred in these areas, resulting in uneven mixing of the slurry, stratification and precipitation of the slurry, and the ore and water cannot be fully contacted and separated, thereby reducing the dehydration efficiency and quality. Summary of the invention

[0004] The object of the present invention is to provide a mining dehydration stirring barrel and a method for using the same. By setting a mineral stirring mechanism, the problem that the stirring paddle of the existing mining dehydration stirring barrel is not convenient for timely adjustment during use due to its fixed position, making it difficult for the ore to be fully stirred in these areas, resulting in uneven mixing of the ore slurry, stratification and precipitation of the ore slurry, and preventing the ore and water from fully contacting and separating, thereby reducing the dehydration efficiency and quality problem is solved.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a dehydration stirring barrel for mining, comprising a stirring barrel and a cylindrical filter plate fixedly connected to the inner wall of the bottom of the stirring barrel; The mixing barrel is provided with a mineral mixing mechanism and a liquid mixing mechanism, the mineral mixing mechanism comprises a mineral mixing component 1 and a mineral mixing component 2, the mineral mixing component 1 comprises a reciprocating screw rotatably connected to the inner wall of the bottom of the mixing barrel, the top of the reciprocating screw rotates and extends outside the mixing barrel, a lifting block is threadedly connected to the outer wall of the reciprocating screw, the front side, the rear side, the left side and the right side of the lifting block are rotatably connected to a rotating shaft 1, a plurality of stirring rods 1 are fixedly connected to the outer walls of the rotating shafts 1, a plurality of racks are fixedly connected to the inner wall of the cylindrical filter plate, a plurality of gears 1 are fixedly connected to the outer walls of the rotating shafts 1 away from the lifting block, and a plurality of gears 1 are respectively meshed with a plurality of racks.

[0006] Furthermore, the mineral stirring assembly 2 includes a rectangular support plate rotatably connected to the outer wall of the reciprocating screw, and L-shaped connecting rods are fixedly connected to the front, rear, left and right outer walls of the rectangular support plate, and the bottoms of several of the L-shaped connecting rods are fixedly connected to the cylindrical filter plate.

[0007] Furthermore, a plurality of sliding rods are fixedly connected to the bottom of the rectangular support plate, and the bottoms of the plurality of sliding rods slide through the lifting block and extend to the outside. A motor is fixedly connected to the top of the mixing barrel, and the output shaft of the motor is fixedly connected to the reciprocating screw through a coupling.

[0008] Furthermore, the liquid stirring mechanism includes a liquid stirring component and a limiting component. The liquid stirring component includes a cross support plate fixedly connected to the outer wall of the reciprocating screw rod, and a gear ring is fixedly connected to the inner wall of the stirring barrel.

[0009] Furthermore, a plurality of rotating shafts 2 are rotatably connected to the bottom of the cross support plate, and a plurality of stirring rods 2 are fixedly connected to the outer walls of the plurality of rotating shafts 2.

[0010] Furthermore, a plurality of gears 2 are fixedly connected to the outer walls of the rotating shafts 2, and a plurality of gears 2 are meshed with the gear ring. A motor waterproof cover is fixedly connected to the top of the mixing barrel, and the motor waterproof cover is adapted to the motor.

[0011] Furthermore, the limiting assembly includes a rotation groove opened on the mixing barrel, and a clamping ring is fixedly connected to the outer wall of the reciprocating screw, and the outer wall of the clamping ring rotates and extends into the rotation groove.

[0012] Furthermore, a feed funnel is fixedly connected to the top of the mixing barrel, a plurality of feed holes are opened on the top of the mixing barrel, a liquid outlet pipe is connected to the outer wall of the mixing barrel, a mineral outlet pipe is connected to the bottom of the mixing barrel, and valves are provided on the liquid outlet pipe and the mineral outlet pipe.

[0013] A method for using a mining dehydration mixing barrel comprises the following steps: S1: First, place the device at the corresponding position, pour the ore to be dehydrated into the cylindrical filter plate in the mixing barrel through the feed funnel and the feed hole, and then start the motor in the motor waterproof cover. The motor will drive the reciprocating screw to rotate stably under the cooperation of the rotating groove and the clamping ring. When the reciprocating screw rotates, the lifting block will also move up and down under the action of the sliding rod on the rectangular support plate, thereby driving the stirring rod 1 on the rotating shaft 1 to move up and down. When the rotating shaft 1 moves up and down, the gear 1 will drive the rotating shaft 1 to rotate under the action of the rack, and then drive the stirring rod 1 to rotate. Therefore, the stirring rod 1 will rotate while moving up and down, and the ore in the cylindrical filter plate will be evenly stirred; S2: When the reciprocating screw rotates, since the cross support plate is fixedly connected to the reciprocating screw, the cross support plate will also be driven to rotate when the reciprocating screw rotates, thereby driving the stirring rods 2 on the plurality of rotating shafts 2 to revolve around the reciprocating screw. In this process, due to the setting of the gear ring, it will drive each rotating shaft 2 to rotate with the cooperation of the gear 2, so that the liquid between the stirring barrel and the cylindrical filter plate is evenly stirred by the stirring rods 2 to avoid precipitation. S3: After the mixing is completed, first open the valve on the liquid outlet pipe to allow the liquid in the mixing barrel to flow out of the device through the liquid outlet pipe. Due to the setting of the cylindrical filter plate, the larger minerals will remain in the cylindrical filter plate, while the smaller minerals or impurities will flow out of the device with the water flow until the water in the mixing barrel is drained. Then open the valve on the mineral discharge pipe to take out the remaining minerals in the mixing barrel. The present invention has the following beneficial effects: (1) The present invention provides a mineral stirring mechanism. When the mineral needs to be dehydrated, the mineral to be dehydrated can be poured into the cylindrical filter plate in the stirring barrel through the feed funnel and the feed hole, and then the motor in the motor waterproof cover is started. The motor drives the reciprocating screw to rotate stably under the cooperation of the rotating groove and the clamping ring. When the reciprocating screw rotates, the lifting block also moves up and down under the action of the sliding rod on the rectangular support plate, thereby driving the stirring rod 1 on the rotating shaft 1 to move up and down. When the rotating shaft 1 moves up and down, the gear 1 drives the rotating shaft 1 to rotate under the action of the rack, and then drives the stirring rod 1 to rotate. Therefore, the stirring rod 1 rotates while moving up and down, and the ore in the cylindrical filter plate is uniformly stirred, so that the slurry can be fully turned over and mixed in all directions, avoiding the occurrence of stirring dead corners, so that the ore particles and water in the slurry can be more evenly distributed, thereby improving the dehydration effect, and can also effectively prevent the ore particles from settling and accumulating at the bottom of the stirring barrel, ensuring that the ore particles are always in a suspended state, which is conducive to the full separation of water and improves the filtration efficiency. (2) The present invention provides a liquid stirring mechanism. When the reciprocating screw rotates, since the cross support plate is fixedly connected to the reciprocating screw, the cross support plate is also driven to rotate when the reciprocating screw rotates, thereby driving the stirring rods 2 on the plurality of rotating shafts 2 to revolve around the reciprocating screw. In this process, due to the setting of the gear ring, it will drive each rotating shaft 2 to rotate under the mutual cooperation of the gear 2, so that the liquid between the stirring barrel and the cylindrical filter plate is evenly stirred by the stirring rod 2 to avoid precipitation, so that the liquid can be stirred in all directions and at multiple angles, avoiding the stirring dead corners that may occur in the traditional single stirring method, thereby achieving a more uniform stirring effect, which is beneficial to the subsequent dehydration and separation process, avoiding the problems of equipment blockage and reduced dehydration efficiency caused by precipitation, and can also improve the filtration efficiency of the cylindrical filter plate for water, reduce the residual water in the ore particles, and further optimize the dehydration effect.
