Description

Technical Field

[0001] The invention belongs to the technical field of ball mills, in particular to a ball mill for treating gas ash. Background Art

[0002] Gas ash, also known as furnace dust, is a fine-grained solid charge carried out when coal gas rises during the ironmaking process of a blast furnace. It is mainly composed of a mixture of mineral powder and coke powder. After being recycled, it can be used as a sintering ingredient in sintering plants, and can also be used as an ingredient for burning cement. The treatment of gas ash usually adopts a ball mill, which uses grinding balls loaded inside a high-speed rotating cylinder to impact and grind the fly ash, turning the large particles into fine powder, thereby changing its physical size state.

[0003] During the operation of the ball mill, the loading capacity of the grinding balls should not be too large or too small, usually about 30% of the cylinder volume. In order to avoid blockage or insufficient grinding caused by too much at one time, existing equipment often uses uniform feeding equipment to feed the materials. However, uniform feeding will cause the feeding to be not fast enough. When the grinding balls in the ball mill are idling, the collision and friction between the grinding balls and between the grinding balls and the cylinder lining of the ball mill will intensify. Since there is no buffering and barrier of the material, the service life of the grinding balls and the lining will be shortened. In addition, the dust generated during the grinding process fills the cavity, which also reduces the effective contact and collision opportunities between the material and the grinding balls, resulting in a decrease in grinding efficiency.

[0030] The raw material will continuously slide in the spiral plate 74. Under the uniform rotation of the circular shaft 73, the raw material will pass through the spiral layer of the spiral plate 74 and enter the double-ended elbow pipe 71. At this time, the blower fan 77 is started again, and the blower fan 77 rotates to absorb the wind at the top and send the wind through the L-shaped pipe 75 to the bending part of the double-ended elbow pipe 71 to blow the raw material there. The air duct of the L-shaped pipe 75 is located in the middle of the two feeding pipes 72, and the raw material falling into the double-ended elbow pipe 71 can be blown to realize the rapid falling of the raw material into the housing 31, which solves the problem that the existing equipment often uses uniform feeding equipment for feeding, but the uniform feeding will cause the feeding to be not fast enough, and the grinding balls in the ball mill will shorten the service life of the grinding balls and the liner 36 when the grinding balls in the ball mill are idling;

[0031] The discharge assembly 2 includes a support seat 21, a discharge pipe 22 is installed through the middle upper part of the support seat 21, the inner wall of the discharge pipe 22 has four arc strips 23 in a circular array, a sun gear 24 is fixedly connected to the outer edge of the right side of the discharge pipe 22, three planetary gears 25 are meshed on the outer edge of the sun gear 24, a gear ring 26 is meshed on the outer edges of the three planetary gears 25, a support block 27 is fixedly connected to the bottom side of the gear ring 26, the support block 27 is fixedly connected to the bottom plate 1, and the right end of the discharge pipe 22 is fixedly connected to the left end pipe of the inner shell 35;

[0032] When the inner shell 35 is driven to rotate by the reduction assembly 6 and the transmission assembly 5, the discharge assembly 2 on the left side thereof will also rotate in the support seat 21, and the ground material will be guided to be discharged through the arc strip 23 installed around it.

[0034] The inner shell 35 rotates in the outer shell 31, and the diameter of the raw material will continue to decrease after the grinding balls collide and grind here; when the equipment is rotating and grinding, the grinding balls are in different positions in the inner shell 35, which will generate centrifugal force. At this time, the multiple springs 33 on the outside of the outer shell 31 that are hinged by the connecting piece 32 can absorb part of the centrifugal force;

[0035] The dust removal assembly 4 includes a rectangular block 41, which is fixedly mounted on the top of the housing 31. Two outlet fans 42 are installed in the rectangular block 41.

At this time, the two square plates 43 move to the left and right sides of the rectangular block 41 to expose the duct where the outlet fans 42 are located. At this time, the two outlet fans 42 are started to generate wind from bottom to top. When the inner shell 35 is constantly rotating, the multiple air holes opened therein overlap with the duct position of the rectangular block 41 each time, part of the dust can be discharged from the inner shell 35, which solves the problem that the dust generated during the grinding process fills the cavity and reduces the effective contact and collision opportunities between the material and the grinding balls, resulting in a decrease in grinding efficiency.

[0037] The transmission assembly 5 includes two support rods 51, which are fixedly mounted on the right side of the outer shell 31. An annular guard plate 52 is fixedly mounted on the top of the two support rods 51. A large gear 53 is movably engaged inside the annular guard plate 52. The inner side of the large gear 53 is fixedly connected to the right side pipe of the inner shell 35. A small gear 54 is meshed on the outer edge of the large gear 53.

[0038] After being driven by the reduction assembly 6, the small gear 54 rotates, and then transmits the rotational force to the large gear 53, so that the inner housing 35 can rotate in the outer housing 31;

[0039] The reduction assembly 6 includes a square housing 61, which is fixedly mounted on the right side of the pinion 54. A first gear 62 is rotatably mounted in the square housing 61.

[0040] The motor 66 rotates clockwise, first driving the third gear 64 in the square housing 61 to rotate. The third gear 64 transmits the rotational force to the first gear 62 through the second gear 63, and then transmits it to the transmission assembly 5 after a deceleration and torque amplification by the fourth gear 65.

[0041] Working principle:

[0042] When using the present invention, firstly, the raw material to be ball-milled is placed in the feed assembly 7, and the raw material will continuously slide in the spiral plate 74. Under the uniform rotation of the circular shaft 73, the raw material will pass through the spiral layer of the spiral plate 74 and enter the double-ended elbow 71. At this time, the blower fan 77 is started again, and the blower fan 77 rotates to absorb the wind at the top, and sends the wind through the L-shaped tube 75 to the bending part of the double-ended elbow 71 to blow the raw material there. The air duct of the L-shaped tube 75 is located in the middle of the two feed tubes 72, and the raw material falling into the double-ended elbow 71 can be blown, so that the raw material quickly falls into the housing 31.

[0043] When the raw material enters the inner shell 35, the deceleration assembly 6 is started, and the motor 66 rotates clockwise, first driving the third gear 64 in the square shell 61 to rotate. The third gear 64 transmits the rotational force to the first gear 62 through the second gear 63, and then transmits it to the small gear 54 after a deceleration and torque amplification of the fourth gear 65. The small gear 54 then transmits the rotational force to the large gear 53. At this time, the inner shell 35 can be rotated in the outer shell 31. A plurality of grinding balls are placed in the inner shell 35 in advance. After the raw material is ground by the collision of the grinding balls, its diameter will continue to decrease. When the equipment is rotating and grinding, the grinding balls are in different positions in the inner shell 35, which will generate centrifugal force. At this time, the plurality of springs 33 on the outside of the outer shell 31 that are hinged by the connecting piece 32 can absorb part of the centrifugal force.

[0044] When the inner shell 35 is grinding and generating floating dust, the two sets of hydraulic rods 44 shorten their strokes, and the two square plates 43 move to the left and right sides of the rectangular block 41 to expose the duct where the outlet fans 42 are located. At this time, the two outlet fans 42 are started to generate wind from bottom to top. When the inner shell 35 is rotating continuously, the multiple air holes opened therein overlap with the duct position of the rectangular block 41 each time, so that part of the dust can be discharged from the inner shell 35;

[0045] When the inner shell 35 is driven to rotate by the reduction assembly 6 and the transmission assembly 5, the discharge assembly 2 on its left side will also rotate in the support seat 21, and the ground material will be guided out through the surrounding arc bar 23. The sun gear 24 and the three meshing planetary gears 25 rotate in the fixed gear ring 26, so that the discharge pipe 22 can withstand a larger power and torque load, disperse the load, and reduce the pressure on the arc bar 23 during discharge. The work process ends here.
