Description

Technical Field

[0001] This utility model relates to the field of ball casting production, specifically a hydraulic cooling device for ball casting production. Background Technology

[0002] Cast balls, a widely used wear-resistant material in industries such as mining, cement, power, and chemicals, play a crucial role in material crushing and grinding processes. Their performance directly affects the operating efficiency and service life of related production equipment. The production process of cast balls mainly includes smelting, molding, casting, cooling, and post-processing, with the cooling process being the most critical stage in determining the quality and performance of the cast balls.

[0003] In the production of cast balls, the main purpose of the cooling process is to ensure that the cast balls solidify at a suitable cooling rate after pouring, thereby achieving the desired microstructure and mechanical properties. Hydraulic cooling equipment uses a pump to apply pressure to the coolant, moving it along a conveying path and spraying it onto the surface of the cast balls to cool them. For example, the Chinese authorized patent with announcement number CN 218693803 U (a water-cooling device for the production of wear-resistant cast balls) includes a shell, with several support feet at the bottom of the shell, a ball-collecting device at the top of the shell, a coolant storage tank in the middle of the bottom of the shell, and a cooling channel matching the ball-collecting device at the top of the shell. The cooling channel is spring-shaped. The beneficial effects are: by setting up a motor, collecting roller, traction rope, collecting box, and elongated opening, the wear-resistant cast balls can be automatically brought out from the coolant storage tank, and the tilt of the collecting box can be adjusted. At the same time, with the help of a fixing plate, lifting device, through groove, sliding plate, support feet, threaded rod, and mounting holes, the falling height of the wear-resistant cast balls into the collecting box can be reduced, the collision of the wear-resistant cast balls can be reduced, and the degree of damage to the surface of the wear-resistant cast balls can be reduced.

[0004] Although the aforementioned prior art has the function of cooling the cast balls, the cast balls move in a rolling motion along the preset path, and the rolling axis moves along the channel trajectory, so that the relative positions of the surfaces close to the channel axis and the surfaces far from the channel axis remain unchanged. As a result, the cast balls cannot be cooled evenly, and the surface is prone to cracks and other problems. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic cooling device for the production of cast balls, in order to solve the problem mentioned in the background art that when the cast balls move along a preset path, they are in a rolling motion, so that the relative positions of the surfaces near the channel axis and the surfaces away from the channel axis remain unchanged, and the cast balls cannot be cooled uniformly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-6 One embodiment of this utility model is a hydraulic cooling device for ball casting production, which includes a support frame 1. The support frame 1 is welded and fixed to the lower end of the cooling shell 2 to provide stable support for the entire device.

[0020] A ball-casting channel 3 is connected to the cooling shell 2. The ball-casting channel 3 includes an inlet channel 4, a spiral cooling channel 5, and an outlet channel 6. The inlet channel 4 is integrally connected to the upper end of the spiral cooling channel 5, and the outlet channel 6 is integrally connected to the lower end of the spiral cooling channel 5. The inlet channel 4 and the outlet channel 6 are arranged in opposite directions, both extending outwards and inclined. An inlet / outlet slot 7 is provided at the contact position between the end face of the cooling shell 2 and the spiral cooling channel 5. The ball body 16 is conveyed into the spiral cooling channel 5 through the inlet / outlet slot 7 and then enters the interior of the cooling shell 2 along the spiral cooling channel 5, allowing the ball to smoothly enter and leave the cooling area. The main body of the spiral cooling channel 5 is located at the upper end of the interior of the cooling shell 2, and its pitch gradually decreases from top to bottom. This gradually decreasing pitch design gradually increases the channel restriction on the ball body 16 as it rolls downwards, which helps to control the speed and posture of the ball. In conjunction with the subsequent cooling structure, it can achieve dynamic adjustment of the cooling effect. A cooling space 10 is formed within the spiral cooling channel 5, and several cast ball bodies 16 are arranged within the cooling space 10.

[0021] A side slot 9 is formed in the middle of the inner and outer sides of the spiral cooling channel 5. Multiple attitude adjustment components 11 are spirally arrayed within the outer side slot 9. Each attitude adjustment component 11 includes a central rotating shaft 12, located within the side slot 9 and rotatably connected to the spiral cooling channel 5. A baffle plate 13 is fixed to the outer center of the central rotating shaft 12, and the baffle plate 13 is positioned within the cooling space 10. A pressure spring 14 is installed along the outer side of the central rotating shaft 12 between the baffle plate 13 and the spiral cooling channel 5. Multiple rubber strips 15 are arrayed and fixed to the inner side of the baffle plate 13. When the cast ball body 16 rolls within the spiral cooling channel 5, the baffle plate 13 on the attitude adjustment component 11 blocks the rolling of the cast ball body 16 within the cooling space 10. After the cast ball body 16 contacts the baffle plate 13, gravity exerts a certain force on the baffle plate 13, causing the baffle plate 13 to rotate about the central rotating shaft 12. The pressure spring 14 rotates and compresses, and the rubber strips 15 contact the cast ball body 16. As the cast ball body 16 is conveyed downwards, it rotates about an axis perpendicular to the bottom surface of the spiral cooling channel 5, adjusting its own posture. Under the action of the pressure spring 14, the baffle plate 13 rotates to reset and adjust the posture of the next cast ball body 16.

[0022] The lower end of the spiral cooling channel 5 inside the cooling housing 2 is configured as a lower liquid storage chamber 19. A liquid inlet pipe 20 is installed on the upper end of the lower liquid storage chamber 19 on one side of the cooling housing 2 to facilitate the replenishment of coolant into the equipment, ensuring sufficient coolant to maintain normal cooling operation and improving the equipment's working efficiency. A coolant delivery pump 17 is installed at the upper end of the cooling housing 2. The input end of the coolant delivery pump 17 is connected to a delivery pipe 18, and the other end of the delivery pipe 18 extends to the lower end of the lower liquid storage chamber 19.

[0023] Multiple annular pipes 23 are arranged from top to bottom on the exterior of the cooling housing 2, with the spacing between adjacent annular pipes 23 gradually decreasing from top to bottom. Multiple distribution pipes 25 are installed in a ring array on the inner side of the annular pipes 23, with the distribution pipes 25 on the inner side of adjacent annular pipes 23 arranged alternately. The inner side of the distribution pipes 25 extends into the cooling housing 2 and is equipped with coolant nozzles 26, which are oriented towards the spiral cooling channel 5. The output end of the coolant delivery pump 17 is connected to a main drain pipe 21, and the output end of the main drain pipe 21 is connected to a delivery pipe 22. A connecting pipe 24 connects the delivery pipe 22 and the annular pipes 23.

[0024] The coolant delivery pump 17 draws coolant from the lower storage chamber 19 through the delivery pipe 18 and pumps it out through the drain manifold 21. The drain manifold 21, delivery pipe 22, connecting pipe 24, annular pipe 23, distribution pipe 25, and coolant nozzle 26 are internally connected. During operation, the coolant delivery pump 17 starts, draws coolant from the lower storage chamber 19 through the delivery pipe 18, delivers it through the drain manifold 21, delivery pipe 22, and connecting pipe 24 to the annular pipe 23, and then sprays it onto the casting ball body 16 through the distribution pipe 25 and the coolant nozzle 26. As the spacing of the annular pipe 23 gradually decreases from top to bottom, and the pitch of the spiral cooling channel 5 also gradually decreases from top to bottom, the cooling effect of the coolant on the casting ball body 16 gradually increases as the casting ball body 16 rotates downwards. This allows the cast balls to adapt to cooling slowly in the initial stage, avoiding stress concentration caused by excessively rapid cooling. As the cast balls move downwards, the cooling intensity gradually increases, ensuring that the cast balls are fully cooled, greatly improving the cooling quality and uniformity of the cast balls. The sprayed liquid enters the lower liquid storage chamber 19 and is pumped back, realizing the recycling of the coolant.

[0025] The spiral array on the lower end face of the spiral cooling channel 5 has multiple lower through-hole grooves 8. These lower through-hole grooves 8 help the coolant flow smoothly into the lower liquid storage chamber 19, ensuring the smooth circulation of the coolant.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
