Description

Technical Field

[0001] The invention belongs to the technical field of slurry grinding, and in particular relates to a bauxite slurry grinding device. Background Art

[0002] Alumina production mostly uses bauxite as the main raw material. After the bauxite is crushed, it is ground into bauxite slurry with qualified particle size by adding appropriate circulating alkali solution, and then goes through pre-desiliconization, dissolution, decomposition, aluminum hydroxide filtration and roasting to finally produce finished alumina. Raw material grinding is one of the important processes in alumina production. The solid content (the content of solid mineral particles) of the slurry after grinding has a very important influence on the subsequent pre-desiliconization, dissolution and other processes.

[0003] To achieve precise control of the solid content in the slurry, we must first ensure the accurate metering of raw materials such as bauxite and circulating alkali solution to control the ratio and solid content of the raw materials; Because the bauxite at this point has not been fully ground into powder, but has been initially crushed into pieces, it is impossible to accurately sense and control the amount through the valve opening time like powdered materials; if the amount of bauxite is unknown, there is naturally no way to control the amount of circulating alkali solution.

[0004] The current control method is to test the solid content of the slurry at the discharge point at the back end, and in turn control the amount of liquid added at the front end; this lagging adjustment method actually has a weak control over the solution and is far inferior to accurately controlling the amount of bauxite and circulating alkali solution added when the materials are added. Summary of the invention

[0040] The grinding assembly 39 includes a slurry grinding cylinder 42, on which a top feed hopper 48 is provided. The rotary drive assembly 4 includes a feed motor 6 and a beam-type rotating bracket 7. The beam-type rotating bracket 7 is fixedly connected to the inside of the top feed hopper 48. The feed motor 6 is fixedly connected to one end of the top feed hopper 48. A central sealing circular hole 11 is provided on the beam-type rotating bracket 7.

[0041] The weight sensing assembly 5 includes a rotating unloading box 8, a loading plate 9, a fixed baffle 51 and a tension spring 10. A blind sleeve 12 is provided at one end of the rotating unloading box 8. The blind sleeve 12 is sleeved on the output shaft of the feeding motor 6. The output shaft of the feeding motor 6 and the blind sleeve 12 are fixedly connected. A through sleeve 13 is provided at the other end of the rotating unloading box 8.

[0042] The sinking of the carrier plate 9 together with the sensing piston plate 50 can reflect the mass of the heavy objects on the carrier plate 9 at this time, and thereby adjust the flow of the transmission fluid in the rotating unloading box 8 and the rotating control sleeve 19, thereby achieving the technical purpose of automatically controlling the position of the adaptive locking piston assembly 16.

[0043] The liquid adding mechanism 2 includes a rotary adding component 15, an adaptive locking piston component 16 and a telescopic transmission component 17. The rotary adding component 15 is arranged on the grinding component 39, the adaptive locking piston component 16 is slidably arranged in the rotary adding component 15, and the telescopic transmission component 17 is arranged on the adaptive locking piston component 16.

[0044] By sliding the adaptive locking piston assembly 16, the single liquid inflow volume of the rotary control sleeve 19 can be changed in each liquid inflow cycle, thereby achieving a technical effect of matching the amount of bauxite solids and circulating alkali solution entering the slurry grinding cylinder 42.

[0045] The rotary adding component 15 includes a fixed cylindrical sleeve 18 and a rotating metering sleeve 19. The fixed cylindrical sleeve 18 is fixedly connected to the top feed hopper 48. A liquid inlet pipe 27 is provided at the top of the fixed cylindrical sleeve 18, and a liquid discharge window 28 is provided at the bottom of the fixed cylindrical sleeve 18. The liquid inlet pipe 27 and the liquid discharge window 28 are located at the same end of the fixed cylindrical sleeve 18. A side circular hole 29 is provided at the other end of the fixed cylindrical sleeve 18. The rotating metering sleeve 19 is rotatably arranged in the fixed cylindrical sleeve 18.

The rotating metering sleeve 19 is rotatably arranged in the central sealing circular hole 11 through the end joint 31, and a flower tooth portion 32 is evenly distributed in an annular manner on the end joint 31.

[0046] Through the intermittent cooperation of the tooth part 14 and the tooth part 2 32, the rotating discharge box 8 will first push outward through the rotation of the rotating drive rod 23 to achieve the position locking of the adaptive locking piston assembly 16 at the initial stage of rotation, and then rotate with the rotating control sleeve 19. By locking first and then rotating, the position of the volume control piston plate 20 can be maintained unchanged during the flipping and unloading of the rotating discharge box 8, thereby avoiding the tilting and flipping of the rotating discharge box 8 causing changes in the liquid intake amount in the rotating control sleeve 19.

[0047] The adaptive locking piston assembly 16 includes a volume control piston plate 20, a sealing ring 21 and a sliding top block 22. The volume control piston plate 20 is slidably arranged in the rotating volume control sleeve 19. The sealing ring 21 is arranged between the volume control piston plate 20 and the rotating volume control sleeve 19. A circular blind hole 33 is provided in the middle position of the volume control piston plate 20. An annular protrusion 34 is provided on the volume control piston plate 20. Straight sliding grooves 35 are evenly distributed in an annular manner on the annular protrusion 34. The sliding top block 22 is engaged and slidably arranged in the straight sliding groove 35.

[0048] On the one hand, the sealing ring 21 has a sealing function and can isolate the materials and transmission fluid on both sides. On the other hand, through the expansion of the sliding top block 22, it can also increase the extrusion pressure and friction force between the inner wall of the rotary control sleeve 19 and the sealing ring 21, thereby achieving the technical purpose of locking the volume control piston plate 20.

[0049] The telescopic transmission assembly 17 includes a rotating drive rod 23, a polygonal sleeve rod 24, an articulated base 25 and a top support rod 26. The rotating drive rod 23 is composed of a hollow base 36 and a polygonal rod 37. The rotating drive rod 23 is fixedly connected to the through sleeve 13 through the hollow base 36. The polygonal sleeve rod 24 and the polygonal rod 37 are slidably connected in engagement. A circular boss 38 is provided at the bottom of the polygonal sleeve rod 24, and the circular boss 38 is rotatably arranged in the circular blind hole 33. The articulated base 25 is evenly fixed to the polygonal sleeve rod 24 in an annular manner. The two ends of the top support rod 26 are respectively hinged to the articulated base 25 and the sliding top block 22.

[0050] The telescopic transmission assembly 17, through the support of the support rod 26, can automatically control the synchronous expansion and contraction of each group of sliding top blocks 22 when the polygonal sleeve rod 24 and the volume control piston plate 20 rotate relative to each other, thereby realizing the locking and unlocking of the position of the volume control piston plate 20.

[0051] During specific use, the user first needs to start the grinding motor 44, and drive the grinding spindle 47 to rotate through the meshing transmission of the driving gear 45 and the driven gear 46. While rotating, the grinding spindle 47 can also drive the stirring device and the grinding device located on the grinding spindle 47 to rotate, so as to achieve the grinding of the bauxite inside the slurry grinding cylinder 42 and the sufficient reaction and mixing between the solid and the liquid. In this process, the bauxite slurry that meets the grinding standards can be discharged through the discharge mechanism on the slurry grinding cylinder 42, and new raw materials can be added from the top feed hopper 48. This continuous grinding production method is more efficient than the method of grinding all the raw materials after adding them all at once and then discharging all of them.

[0052] During the continuous grinding process, the feed motor 6 can drive the rotating discharge box 8 to rotate; the specific steps of raw material replenishment are as follows: First, a portion of the bauxite fragments are dropped onto the loading plate 9 through an external feeding device. The rated load capacity of these bauxite fragments is roughly the same as that of the rotating discharge box 8, but their specific weight is unknown. At this time, since the liquid inlet and outlet trough 30 and the liquid inlet pipe 27 overlap, the liquid will enter the rotating control sleeve 19 through the liquid inlet pipe 27; The bauxite fragments press the loading plate 9 downward, and during this process the tension spring 10 is stretched, and the elastic force generated by the tension spring 10 will increase accordingly until a balance state is reached; when the loading plate 9 is pressed downward, the induction piston plate 50 also drops accordingly, and at this time, the transmission fluid in the rotary metering sleeve 19 is sucked into the rotary unloading box 8, and at the same time, the volume control piston plate 20 slides toward the direction of the rotary unloading box 8 under the action of negative pressure, and at this time, the space for storing alkali solution in the rotary metering sleeve 19 will increase; therefore, the more bauxite fragments there are in the rotary unloading box 8, the more alkali solution is added each time the material is unloaded.

[0053] Then, the feed motor 6 drives the rotary discharge box 8 to rotate half a circle. Since the tooth part 14 and the tooth part 2 32 are not tightly connected but have a gap, when the rotary discharge box 8 just starts to rotate, the rotary control sleeve 19 remains fixed due to the friction between itself and the fixed cylindrical sleeve 18. At this time, the rotating drive rod 23 rotates with the polygonal sleeve rod 24, so that a small relative rotation is generated between the polygonal sleeve rod 24 and the volume control piston plate 20. When the polygonal sleeve rod 24 rotates relative to the volume control piston plate 20, the support of the support rod 26 can make each group of sliding top blocks 22 extend synchronously. Through the extrusion of the sliding top block 22, the pressure and friction between the sealing ring 21 and the inner wall of the rotating metering sleeve 19 are greatly increased, thereby realizing the locking of the position of the volume control piston plate 20, and then the rotating metering sleeve 19 will rotate along with the rotating discharge box 8; after half a circle of rotation, the bauxite in the rotating discharge box 8 falls into the slurry grinding cylinder 42, and when the liquid inlet and outlet grooves 30 and the liquid outlet window 28 overlap, the liquid in the rotating metering sleeve 19 will also enter the slurry grinding cylinder 42.

[0054] After unloading is completed, the feeding motor 6 rotates in the opposite direction, and resets the rotating unloading box 8 and the rotating metering sleeve 19. Since the rotation direction of the feeding motor 6 is opposite at this time, the rotating unloading box 8, when it first starts to rotate, still first rotates with the polygonal sleeve 24 through the rotating drive rod 23. After the adaptive locking piston assembly 16 is unlocked, it rotates with the rotating metering sleeve 19. Therefore, when the rotating unloading box 8 and the rotating metering sleeve 19 are reset, the volume control piston plate 20 returns to a state where it can slide freely.
