Description

Technical Field

[0001] The invention belongs to the technical field of ore pulp concentration, and in particular relates to a miniaturized and efficient ore pulp concentrator. Background Art

[0002] A slurry concentrator is a device used in mining, metallurgy, chemical industry and other industries. It is mainly used for the concentration of slurry. Slurry is usually composed of ore, liquid and suspended solid particles. It needs to be concentrated during the ore processing to increase the concentration of useful minerals, reduce wastewater discharge, and reduce transportation and processing costs. The concentration process can reduce the moisture content in the slurry and reduce energy consumption in subsequent treatment processes (such as drying, calcination, etc.). In some water-scarce areas of some mines, concentration technology can also help save water resources, and can effectively reduce waste slag emissions in the slurry and reduce the discharge of pollutants. Through the concentration process, solid particles are separated from liquids to reduce environmental pollution.

[0003] The rake frame and rake blades in the existing slurry concentrators are often fixedly connected. When the concentration or particle size of the slurry changes, the rake blade angle cannot be adjusted to adapt to the new working conditions, which can easily lead to a decrease in the efficiency of the concentration process and even affect the sedimentation effect of the slurry. In addition, different slurry characteristics require stirring of different intensities. The fixed angle will affect the stirring intensity of the rake blades, causing over-stirring or under-stirring. Over-stirring will cause excessive stirring of particles in the slurry, increase energy consumption, and cause uneven distribution of slurry concentration. Conversely, insufficient stirring will make it difficult for solid particles to concentrate and settle. If the slurry particles are unevenly distributed or the concentration is too high, the wear of the rake blade in contact with the slurry will be more serious, shortening the service life of the equipment and increasing maintenance costs.

Wheel 20, one side of the gear 20 is rotatably connected with a support plate 5, the support plate 5 is fixedly connected to the tank body 1, the fixed plate 22 is rotatably connected to the fixed frame 41, and a plurality of transmission columns 40 are fixedly connected to the top surface of the turntable 39, the transmission columns 40 are inclined, and a plurality of transmission columns 40 and the pin member 38 are arranged at an angle of ninety degrees, and a plurality of transmission columns 40 are arranged alternately with a plurality of pins in the pin member 38 at one end away from the turntable 39, and a plurality of pins are arranged in the pin member 38. The transmission columns 40 on the turntable 39 can be inserted into a plurality of pins in the pin member 38 to form a mechanical connection, ensuring that when the turntable 39 rotates, it can be transmitted to other components through the transmission columns 40 to realize force transmission, and the threaded rod 31 is threadedly connected with the first moving block 24, the first A plurality of second moving blocks 30 are arranged on one side of a moving block 24, and a fourth connecting plate 29 is rotatably connected to the top surface of the remaining second moving block 30, and one end of the first connecting plate 26 located at the top of the first moving block 24 is rotatably connected to the second connecting plate 27, which effectively stirs and scrapes the solid matter in the slurry, increases the contact area between the solid and the liquid, and improves the concentration effect. At the same time, it can effectively prevent the sedimentation of the slurry, reduce the blockage problem during the operation of the equipment, and ensure the continuous and efficient operation of the equipment. The other end of the second connecting plate 27 is rotatably connected to the fixed rake frame 23, and the other end of the first connecting plate 26 located at the top of the first moving block 24 is rotatably connected to the third connecting plate 28. The first moving block 24 and the second moving block 30 are hollow structures, and the threaded rod 31 is connected to the second moving block 30. The two movable blocks 24 and 30 are not intersected, and a sliding rod 32 is penetrated and slidably connected with the first movable block 24 and the second movable block 30, and the sliding rod 32 is fixedly connected to the fixed rake frame 23. A worm 36 is internally rotatably connected with the first movable block 24 and the second movable block 30, and a worm wheel 37 is transmission-connected to one side of the worm 36.

Adjusting the angle of the rake blade 25 can optimize the working state according to the specific characteristics of the slurry, so that the concentrator can adapt to a variety of slurry types, improve the versatility and adaptability of the equipment, and is suitable for processing different slurry working conditions. The bottom end of the rake blade 25 is parallel to the bottom surface of the tank body 1, and the penetration end of the rake blade 25 is fixedly connected to the worm wheel 37.

[0027] The working principle of this embodiment is as follows: the slurry is poured into the feed box 4 from the top, and then the first motor 9 is operated to drive the variable pitch screw 8 to rotate. As the pitch of the variable pitch screw 8 gradually increases, the resistance to the flow of the slurry can be reduced to avoid excessive accumulation. The slurry can be smoothly transported under different flow and pressure conditions, thereby improving the transportation efficiency and reducing the risk of blockage, so that the slurry can enter the filter screen 12 through the feed pipe 7.

[0028] Under the action of gravity, the solid particles in the slurry settle downward, and the liquid flows into the partition 10 through the water outlet 13 and the serrated groove 14 at the top of the tank body 1, and then enters the drain pipe 3 through the drain hole 11 for discharge.

[0029] Then the third motor 16 drives the gear 20 to rotate, thereby driving the outer gear ring 19 to rotate synchronously, and then the fixed pipe 17 rotates. Since the fixed pipe 17 is fixedly connected to the fixed disk 22, the fixed pipe 17 rotates, and the fixed disk 22 rotates synchronously, so that the rake blades 25 in the adjustable rake frame mechanism 18 rotate to clean the solids settled inside the tank body 1, so that the solids are gathered at the through hole at the bottom of the tank body 1, and then discharged through the solid discharge pipe 6.

[0030] When faced with slurries of different types of particle sizes and concentrations, the second motor 15 drives the connecting rod 21 to rotate, thereby driving the turntable 39 to rotate, and then driving the pin member 38 to rotate, so that the limit rod 33 rotates. Under the action of the limit bar 34, the worm 36 is driven to rotate, thereby causing the worm wheel 37 to rotate, changing the inclination angle of the rake blade 25, and can finely control the flow and distribution of the slurry, making it easier to stratify particles of different densities, thereby achieving a better sedimentation effect.

[0031] When it is necessary to maintain the rake blade 25 in the tank body 1, after disassembling the entire equipment, the staff can drive the threaded rod 31 to rotate by turning the knob 35, so that the first movable block 24 moves in a linear direction under the action of the slide rod 32. At the same time, the worm 36 in the first movable block 24 and the second movable block 30 slides on the limit rod 33 under the action of the limit bar 34, and with the cooperation of several first connecting plates 26 and third connecting plates 28 and second connecting plates 27 and fourth connecting plates 29, several second movable blocks 30 move simultaneously with the first movable block 24, so that the staff can check the rake blade 25 and related components more comprehensively, reduce omissions during repair, and thus reduce the probability of subsequent failures.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
