[0002] During the production and processing of steel balls, they will inevitably be contaminated with various oils, impurities, and debris generated during the processing. Therefore, before subsequent assembly or further processing, the steel balls need to be thoroughly cleaned. If the cleaned steel balls are not dried promptly and effectively, the residual moisture will cause the steel balls to rust, which will affect their performance and service life. In addition, wet steel balls may also cause other problems during subsequent packaging, transportation or use, such as water stains in the packaging, affecting the packaging appearance and product image, or adhesion between steel balls due to moisture during transportation. Therefore, the drying of steel balls after cleaning is a crucial part of the steel ball production and processing process, and there is a strong industry demand.

[0003] Natural drying is the simplest and most primitive treatment method, which is to place the cleaned steel balls in a well-ventilated place and rely on natural wind and air circulation to gradually evaporate the moisture on the surface of the steel balls. This method may be adopted in some small workshops or when the requirements for steel ball drying are not high and the output is small.

[0004] In addition, there are belt-driven drying and drum-type rotating centrifugal drying, but these drying structures have certain defects; belt-driven drying usually uses hot air for drying, and to ensure the drying effect, a longer transmission distance is usually required to obtain sufficient drying time, so a larger site is required to place the equipment. And the drum-type rotating centrifugal drying, in order to ensure the centrifugal effect, the amount that can be contained inside is limited, the movement effect of the material inside is not good, and the circulation effect of the airflow is relatively general, resulting in low drying efficiency. In order to solve the above problems, the present application provides a drying device for steel balls after cleaning. Utility Model Content

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1 - Figure 6 This application is described in further detail.

[0027] Used for drying steel balls after cleaning, refer to Figure 1 - Figure 6, including a drying box 1, the outside of the drying box 1 is equipped with a heat pump dryer 2, the model of the heat pump dryer 2 is selected according to the actual drying needs, and its function is to convey hot air flow into the drying box 1. Others that achieve the same effect can also replace the heat pump dryer 2. The heat pump dryer 2 conveys hot air flow to the inside of the drying box 1 through a pipeline system, and a feed trough 3 and a discharge trough 4 are provided on the front side of the drying box 1. The feed trough 3 is connected to the external container structure or conveyor belt structure, and periodically conveys wet steel balls to the inside of the drying cylinder 5. The dried steel balls are then conveyed to the external container structure or conveyor belt through the discharge trough 4 for subsequent transportation and processing.

[0028] Spiral blades 56 are evenly distributed along the inner wall of the drying cylinder 5. When the spiral blades 56 rotate in the spiral direction, the drying cylinder 5 stirs the internal steel balls. When the spiral blades 56 rotate in the reverse spiral direction, the steel balls are output from the drying cylinder 5.

[0029] The drying cylinder 5 is composed of a net cylinder 51, a tightening section 511 and an annular section 512 in sequence. The diameter of the annular section 512 is smaller than the diameter of the net cylinder 51. The tightening section 511 is used to connect the two. The outer side of the spiral piece 56 is fitted with the inner wall of the net cylinder 51 and the tightening section 511. The end of the spiral piece 56 extends to the inner side of the annular section 512. The purpose of setting the tightening section 511 is to reduce the possibility of the steel ball overflowing from the side of the annular section 512 as much as possible. The mesh holes are evenly arranged on each side of the net cylinder 51. The mesh hole size is smaller than the steel ball to ensure that the hot air flow can enter the inside of the net cylinder 51 from the outside to dry the steel ball. The outer side of the spiral piece 56 is welded with a plurality of ridges 561 along the axial direction of the net cylinder 51. The ridges 561 are protruded to one side of the axis of the net cylinder 51. The setting of the ridges 561 makes the spiral piece 56 rotate in the spiral direction, which will enhance the movement of the internal steel ball, so that the hot air flow can better pass through the surface of the steel ball and take away the moisture on the surface of the steel ball.

[0030] The outside of the drying drum 5 is provided with a transmission structure for driving the drying drum 5 to rotate. The transmission structure includes a toothed ring 55 welded on the annular segment 512, and a motor 9 that drives the toothed ring 55 through a gear plate 91. The outside of the toothed ring 55 is also covered with a fixed ring 53. A notch 531 is provided at the top of the fixed ring 53. The gear plate 91 meshes with the toothed ring 55 at the notch 531. The horizontal positions on both sides of the fixed ring 53 are rotatably connected to the drying box 1 through a rotating shaft 54. A bracket is provided on the outside of the motor 9. The bracket and the outer wall of the fixed ring 53 are fixedly connected by bolts. The bracket provides support for the fixed ring 53 to ensure the stability of the position of the motor 9. The function of the fixed ring 53 is to stabilize the position of the front end of the drying drum 5 and provide kinetic energy for the rotation of the drying drum 5. The three-phase asynchronous motor 9 controls the forward and reverse rotation through a relay and other structures to realize the forward and reverse transmission of the drying drum 5 to achieve the effect of stirring or discharging. Of course, other types of motors 9 can also be used, and other types of logic control systems can be used to control the forward and reverse rotation of the motor 9.

[0031] A hydraulic cylinder 7 for adjusting the inclination angle of the drying cylinder 5 is arranged at the end thereof, and the hydraulic cylinder 7 is rotatably arranged outside the drying box body 1 .

[0032] The outer side of the end of the drying cylinder 5 is covered with a positioning ring 52, and the drying cylinder 5 and the positioning ring 52 are rotatably connected. The positioning ring 52 and the fixing ring 53 work together to ensure that the position of the drying cylinder 5 inside the drying box 1 remains relatively stable when the drying cylinder 5 rotates. The positioning ring 52 and the drying cylinder 5 are rotatably connected. A movable shaft 521 is welded at the horizontal positions on both sides of the positioning ring 52. The drying box 1 is provided with a movable groove 12 for the movable shaft 521 to penetrate and move. The output end of the hydraulic cylinder 7 is rotatably connected to the movable shaft 521. The movable groove 12 is an arc-shaped structure, and its center coincides with the axial direction of the rotating shaft 54. When the hydraulic cylinder 7 is extended, the movable shaft 521 is pushed to move in the movable groove 12, so that the drying cylinder 5 The cylinder 5 rotates around the rotating shaft 54 ​​to achieve the downward tilt of the annular section 512, so that the reverse rotation of the spiral piece 56 can be better matched to achieve material unloading, and the setting of the spiral piece 56 can reduce the stroke distance of the hydraulic cylinder 7. The principle is: when the spiral piece 56 is not set, the normal rotation angle of the drying cylinder 5 should be at least equal to the inclination angle of the tightening section 511 to ensure that the tightening section 511 is in a horizontal state when unloading; when the spiral piece 56 is set, the inclination angle of the drying cylinder 5 does not need to reach this value, even if it has a certain inclination angle to one side of the net cylinder 51, it can be smoothly transported out of the drying cylinder 5 under the reverse rotation and conveying action of the spiral piece 56. In this way, the volume of the device can be reduced to a certain extent.

[0033] A water receiving hopper 8 is provided inside the drying box 1 below the drying drum 5, and a ventilation slot 11 is provided on the top of the drying box to ensure the outflow of evaporated hot air and avoid secondary interference. In the early stage of drying, the drying drum 5 first uses a rotating centrifugal method to spin dry the water attached to the steel balls. During the spinning process, most of the water will enter the water receiving hopper 8 along the inner wall, or directly enter the water receiving hopper 8, and be discharged to the outside through the channel at the bottom of the water receiving hopper 8 to accelerate the subsequent drying speed.

[0034] Through grooves are provided on both side walls of the drying box body 1, and air grooves 6 are slidably installed in the two through grooves, and an air outlet arranged toward the drying cylinder 5 is provided on one side of the air groove 6, and the air outlet position is covered with a rubber sheet 61, and the air groove 6 is bolted and fixed to the drying box body 1 and can be removed for subsequent maintenance. The top of the rubber sheet 61 arranged at the air outlet position is fixed to the outer wall of the air groove 6, and the bottom is movable. Its purpose is that when the drying structure is not working and spin-drying is in progress, water drops fall on the outer surface of the air groove 6, and the water flow can flow downward along the rubber sheet 61 without entering the inside of the air groove 6.

[0035] The pipeline system includes an air delivery pipe 21 arranged between the output end of the heat pump dryer 2 and the air trough 6; the pipeline system also includes an air delivery trough 13 opened on the back plate of the drying box 1 and connected to the output end of the heat pump dryer 2. The heat pump dryer 2 delivers part of the hot air flow to the air trough 6 through the pipeline system, and the air flow pushes the rubber sheet 61 and is then delivered to the inside of the net tube 51 to dry the inside of the net tube 51; the other part of the hot air is directly delivered to the side of the net tube 51 through the air delivery trough 13 to dry the steel balls. Since most of the water thrown out diffuses to the surroundings, the air permeable trough 11 does not need to be provided with a shielding structure.

[0036] The above describes an exemplary implementation of the drying device for steel balls after cleaning provided by the present disclosure with reference to a preferred embodiment. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
