DETAILED DESCRIPTION
[0027] The preferred embodiments of the present application will be described in more detail below. Although the preferred embodiments of the present application are described below, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application is more thorough and complete, and the scope of the present application can be fully conveyed to those skilled in the art.
[0028] As shown in Figures 1-4 According to one embodiment of the present application, the steel ball tempering basket comprises a bucket body and a spiral lifting body arranged in the bucket body. The bucket body comprises a cylinder 2, a base 4 and a top ring 1. The cylinder 2 is surrounded by a plurality of steel columns. The bottom of the steel column is welded to the base 4, and the top of the steel column is welded to the top ring 1. The top ring 1 is provided with a ball inlet. The inner periphery of the base 4 is provided with a downwardly inclined conical surface 10. The middle part of the conical surface 10 is provided with a ball outlet 11. The spiral lifting body comprises a lifting rod 8, a sleeve 13 welded to the middle part of the lifting rod 8, a spiral partition plate 6 welded to the sleeve 13, and a conical ball block 15 arranged at the lower end of the lifting rod 8. The spiral partition plate 6 is provided with a plurality of first ventilation holes 3. The outer periphery surface of the conical ball block 15 cooperates with the inner periphery of the conical surface 10. When the lifting rod 8 is lifted, the conical ball block 15 closes the ball outlet 11. When the bucket body is lifted, an annular opening is formed between the conical ball block 15 and the conical surface 10.
[0029] By arranging the spiral partition plate 6 in the cylinder, the steel balls 14 entering the ball bucket roll down along the spiral partition plate 6. The adjacent spiral partition plates 6 separate the steel balls 14 in the upper and middle parts of the cylinder 2 layer by layer, avoiding the dense accumulation of the steel balls 14 in the cylinder 2. The plurality of first ventilation holes 3 on the spiral partition plate 6 improve the ventilation effect in the cylinder 2. The outer cylinder 2 is surrounded by a plurality of steel columns, increasing the contact area of the steel balls 14 and the hot air. When the lifting rod 8 is lifted relative to the bucket body, the conical ball block 15 closes the ball outlet. When the bucket body is lifted relative to the lifting rod 8, an annular opening is formed between the conical ball block 15 and the conical surface 10, achieving automatic ball unloading.
[0030] In this embodiment, the conical surface 10 is uniformly provided with a plurality of second ventilation holes 12, and the outer periphery of the base 4 is provided with a plurality of ventilation ports 5. During tempering, hot air can enter the cylinder 2 from the second ventilation holes 12 and the ventilation ports 5, making it easier for hot air to enter the tempering basket from the ventilation ports 5 at the lower part of the base 4, improving the ventilation effect of the steel balls 14 at the bottom of the cylinder, and thus improving the tempering efficiency of the steel balls 14 at the bottom of the tempering basket.
[0031] In the embodiment, as shown in Figure 4 The spiral partition plate 6 is inclined downward, and the steel balls 14 in the cylinder 2 roll downward along the spiral partition plate 6, facilitating the loading and unloading of the steel balls.
[0032] In the embodiment, as shown in Figure 2 The top end of the boom 8 is provided with a lifting ring 7 for closing the ball outlet of the hopper body and lifting the tempering basket.
[0033] In the embodiment, as shown in Figure 2 The outer ring of the base 4 is provided with a support seat 9, which can improve the stability of the placement of the tempering basket.
[0034] In the embodiment, the first ventilation hole 3 and the second ventilation hole 12 are both strip-shaped holes, which ensure the strength of the tempering basket in bearing the steel balls 14. The cylinder 2 is provided with a reinforcing ring (not shown), which is sleeved on the outside of the cylinder and is welded with each steel column, thereby improving the strength of the cylinder 2.
[0035] As shown in Figure 4 After the quenching process of the steel balls 14, the tempering basket is placed at the lower end of the ball guide groove, the steel balls 14 enter the tempering basket from the upper ball inlet of the tempering basket and roll downward along the spiral partition plate 6 until the tempering basket is filled with the steel balls 14, then the lifting ring 7 is lifted, the conical ball stop 15 closes the ball outlet 11 of the base 4, and the tempering basket is sent into the box-type tempering furnace for the tempering process of the steel balls 14. The adjacent spiral partition plates 6 separate the steel balls 14 in the middle and upper parts of the cylinder 2 layer by layer, avoiding the accumulation of the steel balls 14 in the cylinder 2. The multiple first ventilation holes 3 on the spiral partition plate 6 improve the ventilation effect in the cylinder 2, and improve the problem of uneven heating of the accumulated steel balls 14. The base of the ball hopper is provided with a ventilation opening 5 and a second ventilation hole 12, and the cylinder 2 of the ball hopper is surrounded by multiple steel columns, so that hot air more easily enters between the steel balls 14 of the tempering basket from multiple directions of the cylinder 2 of the steel column structure, the first ventilation hole 3, the second ventilation hole 12 and the ventilation opening 5, improving the overall tempering heating efficiency. The ventilation opening 5 is in communication with the bottom of the conical surface 10, and hot air can pass through the inside of the tempering basket, so that the heating speed of the steel balls 14 in the ball hopper is uniform, thereby improving the overall heating uniformity of the steel balls 14.
[0036] After the tempering process of the steel balls 14 is completed, the ball hopper is taken out of the box-type tempering furnace and lifted above the storage area of the steel balls 14. The hopper body is lifted relative to the boom 8 by the starter, so that an annular opening is formed between the conical ball stop 15 and the ball outlet 11, and the unloading of the steel balls is automatically realized.
[0037] The above has described the embodiments of the present application, and the above description is exemplary and is not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
