Description

Technical Field

[0001] The invention relates to the technical field of ball mills, in particular to a high-efficiency and energy-saving desulfurization wet ball mill. Background Art

[0002] Desulfurization refers to the process of removing sulfur-containing components in fuel or flue gas, which is of great significance to the prevention and control of the atmosphere. The most widely used desulfurization technology at present is the gypsum desulfurization process, which uses limestone as a desulfurizer to remove sulfur-containing components in fuel or flue gas. Before desulfurization, a wet ball mill is used to prepare limestone slurry, and then the limestone slurry is used as a desulfurizer. The gypsum desulfurization process has the advantages of mature technology, high desulfurizer utilization rate, wide application and high desulfurization rate.

[0003] Chinese patent CN115254321B discloses a wet ball mill for flue gas desulfurization, including a base, a placement frame fixedly connected to the top of the base by bolts, a ball milling tube rotatably connected to the top of the placement frame, connecting tubes clamped at both ends of the ball milling tube, a driving motor fixedly connected to the top of the placement frame at a position corresponding to one side of the ball milling tube by bolts, a driving gear clamped to the output shaft of the driving motor, and a driven gear fixedly sleeved at a position corresponding to one side of the driving gear on the outside of the ball milling tube. In addition, a screening and circulation mechanism is also provided, which drives the rotating drum and the spiral push plate to rotate through the teeth and convexities, and feeds the raw materials in the feed box into the ball milling tube, so that the ball milling tube rotates to crush the raw materials, and the power is transmitted through the cooperation of the transmission wheel and the belt. In the process of rotating and crushing the ball milling tube, the support rod and the top wheel are driven to rotate, so that the top wheel pushes the limiting wheel and the cross plate to rise.

[0004] The prior art announced above has made improvements in aspects such as screening materials, water injection, and material input and output. However, in terms of crushing materials, the crushing effect is still achieved by rotating the ball mill, driving the steel balls and materials to flip and collide, and no improvement has been made in enhancing the crushing effect.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to solve the technical problem that the prior art has not made improvements in enhancing the crushing effect, such as Figure 1-Figure 10 As shown, the following preferred technical solutions are provided:

[0036] A high-efficiency and energy-saving desulfurization wet ball mill comprises a workbench 1. A motor 2, a reduction assembly 3 and a first bracket 5 are respectively arranged on the top surface of the recessed area of ​​the workbench 1. The motor 2 is used to provide power output, and the reduction assembly 3 converts the high speed of the motor 2 into a low speed. The output end of the motor 2 is fixedly connected to the input end of the reduction assembly 3. A second bracket 6 and a plurality of support assemblies 4 are respectively arranged on the top surface of the raised area of ​​the workbench 1. A ball mill 7 is arranged above the workbench 1. The ball mill 7 is meshedly connected to the output end of the reduction assembly 3. The feed end of the ball mill 7 is rotatably connected to the ball mill 7. The feed end of the ball mill 7 is fixedly connected to the second bracket 6. The discharge end of the ball mill 7 is fixedly connected to the ball mill 7. The discharge end of the ball mill 7 is rotatably connected to the first bracket 5. The first bracket 5 and the second bracket 6 both support and limit the ball mill 7, so that the ball mill 7 can rotate smoothly, and the support assembly 4 plays an auxiliary supporting role for the ball mill 7.

[0037] A circular ring 8 is rotatably mounted on the inner cavity side wall of the ball mill 7 near the discharge end, and a stirring component 9 is rotatably arranged in the inner cavity of the ball mill 7. One end of the stirring component 9 is rotatably mounted on the side wall of the circular ring 8, and the other end of the stirring component 9 is rotatably mounted on the inner cavity side wall of the ball mill 7 near the feed end, and the stirring component 9 is meshedly connected with the ball mill 7, and a plurality of water spray components 10 are embedded and slidably mounted on the stirring component 9.

[0038] When ball milling is performed, the motor 2 is started first, and the motor 2 drives the ball mill 7 to rotate through the reduction assembly 3. Since the feeding end of the ball mill 7 is rotatably connected to the ball mill 7, and the feeding end of the ball mill 7 is fixedly connected to the second bracket 6, the feeding end of the ball mill 7 will not rotate with the ball mill 7 during the rotation of the ball mill 7. The stirring assembly 9 is rotatably mounted on the side wall of the ring 8 and the side wall of the inner cavity of the ball mill 7 near the feeding end, which forms a limiting relationship between the side wall of the discharge end of the ball mill 7, the stirring assembly 9 and the ring 8. When the ball mill 7 rotates, When the ball mill 7 is moving, the side wall of the discharge end of the ball mill 7, the stirring component 9 and the ring 8 will not rotate together with the ball mill 7. Through such an arrangement, when the ball mill 7 rotates, the stirring component 9 will be driven to rotate in the inner cavity of the ball mill 7, and the material in the ball mill 7 will be continuously tumbled, thereby increasing the number of collisions of the material in the ball mill 7, which is conducive to accelerating the crushing speed. Under the condition of consistent crushing requirements, the number of rotations of the ball mill 7 can be reduced through the arrangement of the stirring component 9, thereby improving the crushing efficiency, and no additional power is needed to drive it, thereby achieving the purpose of energy saving.

[0039] After the ball mill is used, high-pressure water is introduced into the stirring assembly 9, and the high-pressure water pushes the water spray assembly 10 out of the stirring assembly 9, and the inner cavity of the ball mill 7 and the steel balls in the ball mill 7 are washed with high pressure. Then, the purpose of enhancing the effect can be achieved through the rotational cooperation between the ball mill 7 and the stirring assembly 9. When the cleaning is completed, the water spray assembly 10 is retracted into the stirring assembly 9, which can not only protect the water spray assembly 10, but also prevent the water spray assembly 10 from being blocked.

[0040] The reduction assembly 3 includes a reducer 31 fixedly mounted on the top surface of the recessed area of ​​the workbench 1 and a driving gear 32 fixedly sleeved on the output end of the reducer 31. The function of the reducer 31 is to convert the high speed of the motor 2 into a low speed.

[0041] The support assembly 4 includes a base 41 fixedly mounted on the top surface of the raised area of ​​the workbench 1 and two pairs of triangular support blocks 42 fixedly mounted on the top surface of the base 41. A rotating wheel 43 is rotatably mounted on the inner walls of the two triangular support blocks 42. The outer peripheral wall of the rotating wheel 43 is arranged to fit the outer peripheral wall of the ball mill 7. The arrangement of the support assembly 4 can provide auxiliary support for the ball mill 7, which not only enables the ball mill 7 to rotate smoothly, but also prevents the ball mill 7 from falling off. Moreover, rolling friction is formed between the rotating wheel 43 and the ball mill 7, which reduces mutual friction while providing supporting force.

[0042] The ball mill 7 includes a barrel 71 and a lining plate 72 fixedly mounted on the inner wall of the inner cavity of the barrel 71. A first sealing plate 73 is fixedly mounted on the end of the barrel 71 close to the first bracket 5. A discharge barrel 78 is connected and fixedly mounted on the outer wall of the first sealing plate 73, and the discharge barrel 78 is rotatably mounted on the first bracket 5. A second sealing plate 74 and a third sealing plate 75 are respectively embedded and rotatably mounted on the end of the barrel 71 close to the second bracket 6. A feed barrel 77 is fixedly mounted on the second sealing plate 74 and the third sealing plate 75. The feed barrel 77 is connected to the inner cavity of the barrel 71, and the feed barrel 77 is fixedly mounted on the second bracket 6. The feed barrel 77, the second sealing plate 74, and the third sealing plate 75 are fixedly mounted. A chamber is formed between the sealing plate 75 and the cylinder 71, and an annular rack 76 is fixedly installed on the inner wall of the inner cavity of the cylinder 71, and the annular rack 76 is arranged in the chamber. The outer wall of the second sealing plate 74 and the inner wall of the second bracket 6 are fixedly connected by a fixing plate 79, which is used to enhance the stability of the installation of the second sealing plate 74. A plurality of first balls 730 are rollingly arranged at the connection between the cylinder 71 and the second sealing plate 74, which are used to reduce the friction between the cylinder 71 and the second sealing plate 74 and extend the service life of the equipment. A driven gear 720 is fixedly sleeved on the outer peripheral wall of the cylinder 71 near one end of the first bracket 5, and the driven gear 720 is meshingly connected with the driving gear 32.

[0043] The cylinder 71 includes a cylinder body 711, and a limiting groove 712 is provided on the inner wall of the inner cavity of the cylinder body 711 at one end close to the second bracket 6. A plurality of first balls 730 are rollingly arranged in the inner cavity of the limiting groove 712, and the second sealing plate 74 is embedded and rotatably installed in the inner cavity of the limiting groove 712. Through the arrangement of the first balls 730, the friction between the limiting groove 712 and the second sealing plate 74 can be reduced.

[0044] The first sealing plate 73 includes a plate body 731 , and a circular groove 732 is provided on the inner wall of the plate body 731 . A plurality of second balls 733 are rollingly arranged in the inner cavity of the circular groove 732 , which can reduce the wear between the circular groove 732 and the ring 8 .

[0045] The circular ring 8 comprises a ring body 81 which is embedded and rotatably installed in the inner cavity of the circular slide groove 732 , and a circular groove 82 is formed on the side wall of the ring body 81 .

[0046] The stirring assembly 9 includes a hollow shaft 91 that is rotatably mounted on the second sealing plate 74 and the third sealing plate 75. The end of the hollow shaft 91 close to the second bracket 6 is connected and fixedly mounted with a water inlet 95. The water inlet 95 is connected to a water pipe for replenishing or flushing the inside of the cylinder 71. The end of the hollow shaft 91 close to the ring body 81 is embedded and rotatably mounted in the inner cavity of the circular groove 82. A first transmission gear 93 is rotatably mounted on the inner side walls of the second sealing plate 74 and the third sealing plate 75. The first transmission gear 93 is meshingly connected to the annular rack 76. A second transmission gear 94 is fixedly sleeved on the outer peripheral wall of the end of the hollow shaft 91 close to the second bracket 6. The first transmission gear 93 is meshingly connected to the second transmission gear 94. A plurality of paddles 92 are also connected and fixedly mounted on the outer peripheral wall of the hollow shaft 91.

[0047] Specifically, when ball milling is performed, the motor 2 is first started, and the motor 2 drives the cylinder 71 to rotate through the reduction assembly 3. Since the feed cylinder 77 is fixedly installed on the second sealing plate 74 and the third sealing plate 75, and the feed cylinder 77 is fixedly installed on the second bracket 6, during the rotation of the cylinder 71, the feed cylinder 77, the second sealing plate 74 and the third sealing plate 75 will not rotate with the ball mill cylinder 7. In addition, since the hollow shaft 91 is rotatably installed on the second sealing plate 74 and the third sealing plate 75, and the end of the hollow shaft 91 close to the ring body 81 is embedded in the circular groove 82 for rotation. In the inner cavity, a limiting relationship is formed between the feed barrel 77, the second sealing plate 74, the third sealing plate 75, the stirring assembly 9 and the ring body 81. When the barrel 71 rotates, the feed barrel 77, the second sealing plate 74, the third sealing plate 75, the stirring assembly 9 and the ring body 81 will not rotate with the barrel 71 and remain in place. Through such an arrangement, when the barrel 71 rotates, the stirring assembly 9 will be driven to rotate in the inner cavity of the barrel 71 through the annular rack 76, the first transmission gear 93 and the second transmission gear 94, and the rotation direction of the barrel 71 is opposite to the rotation direction of the stirring assembly 9.

[0048] During the ball milling process, the cylinder 71 will drive the liner 72 to rotate synchronously. During the rotation process, the liner 72 will lift the steel balls and materials to a set height, and then the steel balls and materials will fall on the liner 72 in the form of a parabola. During this process, the steel balls, materials and the liner 72 will continuously collide to achieve the effect of material crushing. The liner 72 uses a high-strength, corrosion-resistant alloy to replace the original rubber material, which is not only energy-efficient, but also has a service life of more than 3 years. It can also improve the crushing capacity of the ball mill, increase the unit power consumption and production capacity, and reduce the consumption of steel balls. In addition, it can also protect the cylinder 71 and extend the service life of the cylinder 71. When the cylinder 71 rotates, it will bring When the stirring assembly 9 rotates in the opposite direction, the stirring assembly 9 will lift up some of the steel balls and materials on the liner 72 through the paddle 92 during the rotation, and the lifted steel balls will collide with the materials again. This arrangement increases the number of collisions between the materials and the steel balls in the ball mill 7 during the ball milling process, which is beneficial to speed up the crushing speed. Since the cylinder 71 and the stirring assembly 9 rotate in the opposite direction, the collision force between the steel balls, the materials and the liner 72 is increased, and the crushing effect is enhanced. Under the condition of consistent crushing requirements, the number of rotations of the ball mill 7 can be reduced through the arrangement of the stirring assembly 9, thereby improving the crushing efficiency, and no additional power is required to drive it, thereby achieving the purpose of energy saving.

[0049] In order to solve the technical problem that manual flushing of the inside of the wet ball mill leads to incomplete cleaning and splashing of material slurry on the workers, causing health hazards to the workers, such as Figure 1-Figure 4 and Figure 9-12As shown, the following preferred technical solutions are provided:

[0050] The hollow shaft 91 includes a shaft body 911 . A plurality of communication grooves 912 are formed on the outer peripheral wall of the shaft body 911 . The plurality of communication grooves 912 are connected to the plurality of paddles 92 in a corresponding manner.

[0051] The paddle 92 includes a shell 921 that is connected and fixedly mounted on the outer wall of the shaft body 911 . The shell 921 is connected to the connecting groove 912 . A load-bearing plate 922 is fixedly mounted in the inner cavity of the shell 921 .

[0052] The load-bearing plate 922 includes a load-bearing plate main body 9221, on which a special-shaped through groove 9222 is provided, on which a mounting plate 9223 is fixedly installed the inner wall of the inner cavity of the special-shaped through groove 9222, on which a water outlet hole 9224 is provided, in which a blocking column 9225 is fixedly installed the inner cavity of the water outlet hole 9224, and a diameter of the blocking column 9225 is smaller than a diameter of the water outlet hole 9224.

[0053] The water spray assembly 10 includes a high-pressure nozzle 101 embedded and slidably installed in the inner cavity of the special-shaped through groove 9222, and a blocking column 9225 is inserted into the interior of the high-pressure nozzle 101. The high-pressure nozzle 101 and the mounting plate 9223 are elastically connected through a spring 102.

[0054] Specifically, after the ball mill is used, high-pressure water is introduced into the shaft body 911 through the water inlet 95, and the high-pressure water in the inner cavity of the shaft body 911 will enter the inner cavity of the special-shaped through groove 9222 through the connecting groove 912 and the water outlet hole 9224. When the water pressure is greater than the elastic force of the spring 102, the high-pressure water will push the high-pressure nozzle 101 toward the outside of the inner cavity of the special-shaped through groove 9222. When the high-pressure nozzle 101 is pushed out to an appropriate distance, the blocking column 9225 will be drawn out from the inside of the high-pressure nozzle 101. At this time, the high-pressure water can be discharged from the high-pressure nozzle 101. 1 is ejected out to perform high-pressure washing on the inner cavity of the ball mill 7 and the steel balls in the ball mill 7, and then the rotational cooperation between the ball mill 7 and the stirring assembly 9 can achieve the purpose of enhancing the cleaning effect. When the cleaning is completed, the high-pressure nozzle 101 retracts into the inner cavity of the special-shaped through groove 9222 under the elastic force of the spring 102. At this time, the blocking column 9225 will be inserted into the interior of the high-pressure nozzle 101 again. Such a setting can not only protect the water spray assembly 10, but also prevent the water spray assembly 10 from being blocked.

[0055] In the process of wet ball milling, water and materials are generally put into the inner cavity of the ball mill 7 through the feed tube 77. When the water content inside the ball mill 7 is too low during the ball milling process, the crushing efficiency will be affected. The general treatment method is to increase the water flow rate so that a large amount of water and materials are put into the inner cavity of the ball mill 7 through the feed tube 77. If water is injected in this way, the materials and water inside the ball mill 7 cannot be fully mixed in time. When replenishing water, the present design passes high-pressure water into the stirring component 9, and then sprays water on the materials in the ball mill 7 through the water spray component 10. Since the stirring component 9 rotates, the materials will be lifted up. Such a setting can replenish water to the materials in a short time and make the water and materials evenly mixed, which is conducive to the normal crushing work.
