Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel ball manufacturing, and particularly relates to a steel ball screening device. Background Art
[0002] In the grinding and crushing operations, the ball mill steel balls are used as the grinding media in ball mills and semi-autogenous mills. There are impacts, extrusions, grindings, etc. between the steel balls themselves and between the steel balls and the ore, resulting in the ball mill steel balls becoming industrial consumables. The grinding and crushing operations include different crushing grades such as coarse crushing, fine crushing, and fine grinding. Different ball mill models have different ball loading amounts, and it is required that the diameter of steel balls of a certain size and the steel balls of different diameters maintain a certain proportional relationship. The commonly used ball mill steel ball diameters are φ20, φ60, φ80, φ89, φ100, φ110. To meet the market requirements, control the production cost, and improve the equipment utilization rate, a rolling ball production line needs to produce rolling balls of different models in different time periods.
[0003] The rolling balls use bars as raw materials. Generally, the rolling balls need to go through a series of processes such as heating, hot rolling forming, air cooling and cooling, quenching, and tempering to improve the hardness and wear resistance. If there are situations such as roll wear, upper and lower guide plate wear, and failure to adjust in time during the rolling process of the rolling balls, a large number of rolling balls will have unqualified dimensions; after some rolling balls are quenched, due to internal tissue stress and thermal stress, some rolling balls will burst, producing unqualified products such as hemispheres and broken balls, and mixing into the rolling balls with qualified dimensions, which cannot be detected in time and need to be manually sorted later. Manual sorting can only screen the steel balls with obvious unqualified dimensions, with low sorting accuracy, low efficiency, and high cost. Summary of the Utility Model

[0024] The following further describes the specific embodiments of the present utility model in conjunction with the drawings.
[0025] The preferred embodiments of the present utility model will be described in more detail below. Although the preferred embodiments of the present utility model are described below, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.
[0026] As Figures 1 - 5 shown, a steel ball screening device according to an embodiment of the present utility model includes: a pair of sprockets 6, a pair of drive chains 3 connected to the pair of sprockets 6 and arranged vertically, a plurality of ball pushing plates 2 arranged between the pair of drive chains 3, a first sorting bed 4 arranged at the bottom of the upper drive chain, a second sorting bed 9 arranged at the bottom of the lower drive chain, and both the first sorting bed 4 and the second sorting bed 9 are arranged on a sorting bed mounting frame; along the movement direction of the upper drive chain 3, the first sorting bed 4 sequentially includes: a first buffer section 18, a second buffer section 16, a third buffer section 14, a first sorting section 17 arranged between the first buffer section 18 and the second buffer section 16, and a second sorting section 15 arranged between the second buffer section 16 and the third buffer section 14; both the first buffer section 18 and the second buffer section 16 are flat structures, and both the first sorting section 17 and the second sorting section 15 are evenly provided with two first steel columns 19 arranged along the movement direction, the adjacent first steel columns 19 are parallel and equidistant from each other, and a first dimension is provided between the adjacent first steel columns 19; along the movement direction of the lower drive chain 3, the second sorting bed 9 sequentially includes: a fourth buffer section 21, a fifth buffer section 23, a sixth buffer section 25, a third sorting section 22 arranged between the fourth buffer section 21 and the fifth buffer section 23, and a fourth sorting section 24 arranged between the fifth buffer section 23 and the sixth buffer section 25; both the fifth buffer section 23 and the sixth buffer section 25 are flat structures, and both the third sorting section 22 and the fourth sorting section 24 are evenly provided with two second steel columns arranged along the movement direction, the adjacent second steel columns are parallel and equidistant from each other, a second dimension is provided between the adjacent second steel columns, the second dimension is smaller than the first dimension, and the second dimension is smaller than the standard size of the steel balls.
[0027] After some steel ball products are subjected to the quenching process, unqualified products such as broken balls and hemispherical balls will be produced. The steel ball screening device utilizes the space of the drive chain to set up two sorting beds on the upper and lower layers, and each sorting bed is provided with two sorting sections, which can better sort out the steel balls with unqualified sizes. The steel balls with qualified sizes roll out through the second sorting bed on the lower layer, so as to efficiently and quickly complete the sorting work of the steel balls.
[0028] In this embodiment, the ball pushing plate 2 includes a first ball pushing plate 12 and a second ball pushing plate 13 which are arranged at intervals. There is a groove in the middle of the first ball pushing plate 12, and two grooves are symmetrically arranged on both sides of the second ball pushing plate 13. The grooves correspond to the adjacent first steel columns and the adjacent second steel columns respectively. The groove structure of the ball pushing plate 2 can play a role in making the steel balls move along the sorting track on the sorting bed, ensuring that the steel balls are screened by the sorting bed, and better pushing the steel balls to move along the steel columns, so as to achieve the effect of rapid sorting.
[0029] In this embodiment, the third buffer section 14 includes a first flat plate and a first arc plate connected to the first flat plate. The first arc plate bends downward to roll and screen the steel balls larger than the first size along the third buffer section 14. The sixth buffer section 25 includes a second flat plate and a second arc plate connected to the second flat plate. The second arc plate bends downward to roll and screen the steel balls meeting the standard size along the sixth buffer section 25.
[0030] In this embodiment, it further includes four ball guiding plates which are respectively inclined at the bottoms of the second buffer section, the third buffer section, the fifth buffer section and the sixth buffer section. When the steel balls move along the steel columns to the buffer section, the ball guiding plates 5 can gradually lift the steel balls stuck between two steel columns and enter the buffer section.
[0031] In this embodiment, a first waste ball basket 8 is arranged at the lower part of the third buffer section 14. The third buffer section 14 is connected to the first waste ball basket 8 through a guide groove 7. The first waste ball basket 8 is used to collect the steel balls larger than the standard size. Second waste ball baskets 10 are arranged in the third sorting section 22 and the fourth sorting section 24. The second waste ball baskets 10 are used to collect the steel balls smaller than the standard size. A qualified ball basket 11 is arranged at the lower part of the sixth buffer section 25. The qualified ball basket 11 is used to collect the steel balls of qualified size.
[0032] As Figure 1 shown, when the steel ball screening device of this embodiment works, the steel ball screening device is arranged after the quenching process. Through the ball guiding groove 7, the quenched steel balls 1 are introduced into the left end of the first sorting bed 4 of the transmission chain mechanism. As Figure 1As shown by the arrow direction, the steel ball 1 is pushed from left to right along the transmission chain 3 by the ball pushing plate 2. When the steel ball 1 passes through the first sorting bed 4, the unqualified steel balls whose size exceeds the nominal diameter requirement are continuously pushed to the right end of the upper transmission chain 3, and the unqualified steel balls enter the first waste ball basket 8. The remaining steel balls 1 whose size does not exceed the nominal diameter enter the second sorting bed 9 in the lower layer under the action of gravity. The transmission chain 3 pushes the steel ball 1 to move from right to left. When the steel ball 1 passes through the second sorting bed 9, the unqualified steel balls such as hemispherical balls and broken balls smaller than the nominal diameter requirement fall into the second waste ball basket 10 under the second sorting bed 9 due to gravity. After two sorts, the steel balls 1 with unqualified sizes are separated from the steel balls 1 with qualified sizes. The qualified steel balls 1 that meet the nominal diameter requirement enter the qualified ball basket 11 and enter the next low-temperature tempering treatment to eliminate the tissue stress.
[0033] The screening device of this embodiment utilizes the space of the transmission chain to set up upper and lower sorting beds, and each sorting bed is provided with two sorting sections, which can better sort out the steel balls 1 with unqualified sizes. The steel balls 1 with qualified sizes roll out through the second sorting bed 9 in the lower layer, thus efficiently and quickly completing the sorting work of the steel balls.
[0034] The embodiments of the present invention have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
