Description

Technical Field

[0001] The present invention belongs to the technical field of wear-resistant ball production, and specifically relates to an oil control device for the production of wear-resistant balls for ball mills. Background Art

[0002] Wear-resistant balls are a kind of grinding medium used in ball mills for grinding materials in the mills. During the production and processing of wear-resistant balls, quenching oil is required for quenching treatment. After quenching, the wear-resistant balls are fished out from the quenching oil, oil-controlled, and then enter the next process for cooling.

[0003] After the wear-resistant balls are fished out from the quenching oil, the surface will be stained with quenching oil, so it is necessary to perform an oil control treatment on the wear-resistant balls. The existing oil control equipment for the production of wear-resistant balls usually only performs a simple oil control treatment on the wear-resistant balls by using the gravitational force after fishing the wear-resistant balls out of the quenching oil tank. A short oil control time will affect the oil control effect, while a long oil control time will affect the production efficiency of the wear-resistant balls.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the attached drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0024] Referring to Figures 1-5 , a wear-resistant ball production oil control device for a ball mill provided in this embodiment includes: An oil quenching tank 1, with an installation groove opened on the top wall. A pushing cavity 2 is provided inside the side wall and bottom wall of the oil quenching tank 1. The upper end of the pushing cavity 2 extends and penetrates through the top wall of the oil quenching tank 1. A baffle pushing mechanism is provided inside the pushing cavity 2. A temporary storage box 3, arranged on one side of the oil quenching tank 1. The top wall of the temporary storage box 3 is used to hold the wear-resistant balls to be quenched and oiled. The top wall of the temporary storage box 3 is flush with the top wall of the oil quenching tank 1. A rotating motor 4, fixedly installed on the lower surface of the top wall of the oil quenching tank 1. A first driving gear 5 is fixedly provided on the output shaft of the rotating motor 4. An oil control cylinder 6, rotatably arranged in the installation groove through a bearing. A first driven gear 7 is fixedly provided on the oil control cylinder 6. The first driven gear 7 meshes with the first driving gear 5. Under the meshing action of the first driving gear 5 and the first driven gear 7, the oil control cylinder 6 is driven to rotate by the rotating motor 4. A top plate 8, configured to be lifted and slide inside the oil control cylinder 6. The oil control cylinder 6 rotates relative to the top plate 8. The top plate 8 is used to push out the wear-resistant balls inside the oil control cylinder 6. When the top plate 8 slides upward along the oil control cylinder 6, the wear-resistant balls inside the oil control cylinder 6 are pushed out to discharge the wear-resistant balls that have completed oil coating and oil control. A ball pushing plate 9, configured to slide horizontally relative to the top walls of the oil quenching tank 1 and the temporary storage box 3. Two groups of baffles 10 are symmetrically slidably arranged on both sides of the pushing cavity 2. Both groups of baffles 10 are connected to the baffle pushing mechanism. The baffle 10 is configured to be lifted and lowered inside the pushing cavity 2 driven by the baffle pushing mechanism. The baffle 10 is used to assist the ball pushing plate 9 in feeding and discharging the wear-resistant balls. During use, when the baffle 10 inside the side wall of the oil quenching tank 1 far from the temporary storage box 3 is pushed out, a platform is formed above the oil quenching tank 1 and the temporary storage box 3. Under the action of the ball pushing plate 9, the wear-resistant balls to be oiled on the top wall of the temporary storage box 3 are pushed into the oil control cylinder 6 to complete feeding. Through the setting of the baffle 10, it can be avoided that the wear-resistant balls fall from the side of the oil quenching tank 1 far from the temporary storage box 3; when the baffle 10 between the oil quenching tank 1 and the temporary storage box 3 is pushed out, under the action of the ball pushing plate 9, the wear-resistant balls after oil coating and oil control pushed out from the oil control cylinder 6 are pushed down from above the oil quenching tank 1 to complete the discharging action. Through the setting of the baffle 10, it can be avoided that the wear-resistant balls are pushed back to the top wall of the temporary storage box 3 in the reverse direction; Among them, there are multiple sets of oil control cylinders 6 with different diameters. The oil control cylinders 6 with smaller diameters are nested inside the oil control cylinders 6 with larger diameters. The side wall of the oil control cylinder 6 includes a cylindrical outer side wall and an inner side wall. The lower ends of the outer side wall and the inner side wall of the oil control cylinder 6 are connected by a connecting plate 11. The outer side wall and the inner side wall are connected by the connecting plate 11 to form a set of oil control cylinders 6. The upper ends of adjacent two sets of oil control cylinders 6 are connected by a connecting plate 12, and multiple sets of oil control cylinders 6 are connected into a whole by the connecting plate 12; The inner side wall and the outer side wall of a set of oil control cylinders 6 located at the central part are both arranged in a mesh structure. The outer side walls of the remaining multiple sets of oil control cylinders 6 are arranged in a mesh structure. Through the side wall arrangement of the mesh structure of multiple sets of oil control cylinders 6, when the oil control cylinders 6 rotate, the quenching oil in the oil control cylinders 6 can be thrown out, improving the oil control efficiency of the wear-resistant balls. And by setting the inner side walls of multiple sets of oil control cylinders 6 as non-mesh structures, it can be avoided that the quenching oil thrown out by the set of oil control cylinders 6 located inside re-enters the set of oil control cylinders 6 located outside.

[0025] It should be noted that only two sets of oil control cylinders 6 are shown in this embodiment. When two sets or more than two sets of oil control cylinders 6 are set, the connection method between the oil control cylinders 6 can refer to this embodiment.

[0026] It should be noted that, as a preferred technical solution, the distance between the inner side wall and the outer side wall of the oil control cylinder 6 is less than the sum of the diameters of two wear-resistant balls, so as to avoid two wear-resistant balls being on the same horizontal plane and affecting the oil coating and oil control efficiency of the wear-resistant balls.

[0030] Specifically, referring to Figure 3 and Figure 5 , in this embodiment, a pushing mechanism is arranged on the inner bottom wall of the oil quenching tank 1.

The pushing slide bar 24 is connected to the ejecting plate 8. The length of the pushing slide bar 24 is the same as the depth of the oil control cylinder 6. When the ejecting is pushed to the uppermost position, the upper surface of the ejecting plate 8 is exactly flush with the top wall of the oil quenching tank 1; During use, under the action of the electric push rod 22, the ejector plate 8 is pushed to a state level with the top walls of the oil quenching tank 1 and the temporary storage tank 3 through the cooperation of the mounting plate 23 and the ejecting slide rod 24. Under the action of the ball pushing plate 9, automatic feeding and discharging of wear-resistant balls can be achieved.

[0031] Specifically, referring to Figure 1 and Figure 2 , in this embodiment, two groups of protective plates 25 are symmetrically arranged on both sides of the top walls of the oil quenching tank 1 and the temporary storage tank 3. The protective plates 25 are used to guide the wear-resistant balls pushed by the ball pushing plate 9, preventing the wear-resistant balls from falling from both sides of the oil quenching tank 1 and the temporary storage tank 3 during the process of being pushed and moved by the ball pushing plate 9.

[0032] Specifically, referring to Figure 1 and Figure 2 , in this embodiment, a ball pushing mechanism is provided on the top walls of the oil quenching tank 1 and the temporary storage tank 3, and the ball pushing mechanism includes: A support plate 26, fixedly arranged on the top wall of the oil quenching tank 1, and the support plate 26 is perpendicular to the protective plate 25; A ball pushing motor 27, fixedly arranged on the support plate 26; A ball pushing screw rod 28, rotatably arranged on the support plate 26, and one end of the ball pushing screw rod 28 is connected to the output shaft of the ball pushing motor 27; A ball pushing slide rod 29, fixedly arranged on the support plate 26; One end of the ball pushing plate 9 is connected to the ball pushing screw rod 28 through a thread, and the other end of the ball pushing plate 9 is slidably arranged on the ball pushing slide rod 29; It should be noted that a discharge slot is provided on a group of support plates 26 far from the temporary storage tank 3, and the discharge of wear-resistant balls can be achieved through the setting of the discharge slot.

When the valve is opened, the quenching oil in the oil quenching tank 1 flows into the temporary storage tank 3; It should be known that the oil passing pipe 35 can be arranged outside the oil quenching tank 1 and the temporary storage tank 3, or can pass through the pushing cavity 2. When the oil passing pipe 35 passes through the pushing cavity 2, the valve needs to be an automatic valve to be controlled.

[0035] An oil pump 31 is provided outside the oil quenching tank 1 and the temporary storage tank 3. The inlet of the oil pump 31 is connected to the temporary storage tank 3 through an oil delivery pipe 30, and the outlet of the oil pump 31 is connected to the oil quenching tank 1 through an oil delivery pipe 30.

Through the setting of the oil filling pipe 32, quenching oil can be added to the oil quenching tank 1, and through the setting of the oil outlet pipe 33, the quenching oil in the oil quenching tank 1 can be discharged to facilitate the replacement of the quenching oil.

[0037] Specifically, referring to Figure 1 and Figure 2 , in this embodiment, an inclined ball guide plate 34 is provided on the side of the oil quenching tank 1 away from the temporary storage tank 3. During use, a receiving belt or a storage box can be arranged below the ball guide plate 34. Through the setting of the ball guide plate 34, the refractory balls after oil coating and oil control can fall into the receiving belt or the storage box.

[0038] The working principle of a wear-resistant ball production oil control device for a ball mill provided in this embodiment is as follows: (1) First, add quenching oil to the oil quenching tank 1 through the oil filling pipe 32, and the height of the quenching oil needs to be higher than the height of the mesh structure of the oil control cylinder 6.

[0039] (2) When feeding is required, start the position adjustment motor 18 to drive the position adjustment screw 19 to rotate. Under the drive of the position adjustment screw 19 and the guiding action of the position adjustment slide rod 20, drive the position adjustment plate 21 to move. The position adjustment plate 21 drives the pushing motor to move until the second driving gear 13 meshes with the second driven gear 15 of a set of pushing components away from the oil quenching tank 1.

[0040] (3) Start the pushing motor. The pushing motor drives the second driving gear 13 to mesh. Under the meshing action of the second driving gear 13 and the second driven gear 15, drive the pushing screw 14 to rotate. Under the drive of the pushing screw 14 and the guiding action of the pushing slide rod 16, drive the baffle 10 corresponding to this set of pushing components to rise. At this time, a connected platform is formed between the top walls of the oil quenching tank 1 and the temporary storage tank 3.

[0041] (4) Place the wear-resistant balls that need to be quenched on the top wall of the temporary storage box 3, start the ball-pushing motor 27, the ball-pushing motor 27 drives the ball-pushing screw 28 to rotate, and under the drive of the ball-pushing screw 28 and the cooperation of the ball-pushing slide rod 29, the ball-pushing plate 9 is driven to move. During the movement of the ball-pushing plate 9, the steel balls on the upper surface of the temporary storage box 3 are pushed into the oil control cylinder 6.

[0042] (5) Since the quenching oil submerges the wear-resistant balls, the wear-resistant balls are oiled under the action of the quenching oil. After the oiling is completed, open the valve of the oil passing pipe 35, and part of the quenching oil in the oil quenching tank 1 enters the temporary storage box 3. At this time, the oil control cylinder 6 is not submerged in the quenching oil.

[0043] (6) Start the rotating motor 4, the rotating motor 4 drives the first driving gear 5 to rotate, and under the meshing action of the first driving gear 5 and the first driven gear 7, the oil control cylinder 6 is driven to rotate. When the oil control cylinder 6 rotates, efficient oil control of the quenching oil is achieved under the action of centrifugal force.

[0044] (7) After the oil control is completed, first, under the action of the pushing motor, the baffle 10 close to the ball guiding plate 34 is retracted into the pushing cavity 2 through the meshing of the second driving gear 13 and the second driven gear 15. Then, under the action of the position adjusting motor 18, the second driving gear 13 is driven to move towards the group of second driven gears 15 close to the temporary storage box 3. After the second driving gear 13 meshes with this group of second driven gears 15, under the action of the pushing motor, a group of baffles 10 close to the temporary storage box 3 are driven to move out of the pushing cavity 2. At this time, the upper surfaces of the top walls of the temporary storage box 3 and the oil quenching tank 1 are separated.

[0045] (8) Start the electric push rod 22, the electric push rod 22 drives the ejector plate 8 to move upward through the mounting plate 23 and the ejecting slide rod 24. As the ejector plate 8 moves upward, the wear-resistant balls in the oil control cylinder 6 are ejected. When the wear-resistant balls are ejected, they roll along the ball guiding plate 34 and are collected. When the ejector plate 8 is pushed to be flush with the top wall of the oil quenching tank 1, all the wear-resistant balls in the oil control cylinder 6 are ejected. At this time, with the cooperative movement of the ball-pushing plate 9, all the wear-resistant balls on the top wall of the oil quenching tank 1 can be ejected for blanking.

[0046] (9) Before the next quenching and oiling, the quenching oil in the temporary storage box 3 can be pumped back into the oil quenching tank 1 through the oil pump 31.
