Description

Technical Field

[0001] This utility model relates to the field of metal cooling technology, specifically a high-chromium ball cooling device. Background Technology

[0002] High-chromium balls are key wear-resistant materials in industries such as mining and cement. The cooling process after quenching directly affects the hardness, toughness, and crack resistance of the product. In existing technologies, high-chromium balls are generally cooled by a temperature-controlled circulating water cooling pool. In this process, the high-chromium balls are hoisted into the temperature-controlled circulating water cooling pool by a basket. The temperature-controlled circulating water cooling pool dissipates heat through circulating water and controls the water temperature to achieve stable cooling of the high-chromium balls.

[0003] However, in actual use, after the high-chromium ball is quenched, a layer of slag will appear on its surface. After cooling, the slag will fall off and fall into the temperature-controlled circulating water cooling pool. It is not easy to clean the slag and will also affect the cooling effect of the coolant on the high-chromium ball in the temperature-controlled circulating water cooling pool. At the same time, the cooling uniformity of the static high-chromium ball in the temperature-controlled circulating water cooling pool is poor, which can easily cause inconsistent shrinkage between the surface and the core, resulting in micro cracks or macro deformation and affecting the service life. Therefore, a high-chromium ball cooling device is proposed. Utility Model Content

[0006] The dispersion barrel is used to hold high-chromium balls, and the outer wall of the dispersion barrel has multiple sieve holes.

[0007] The lifting unit is mounted on the bracket, and the dispersion tank is mounted on the lifting unit. The lifting unit controls the dispersion tank to enter and exit the temperature-controlled circulating water-cooled pool.

[0008] A drive unit is installed between the lifting unit and the dispersing tank, and is used to drive the dispersing tank to rotate.

[0009] The collection plate is movably placed on the upper surface of the temperature-controlled circulating water cooling pool to cover the opening of the pool.

[0010] Preferably, the lifting unit includes multiple hydraulic cylinders mounted on a bracket and two connecting rings sleeved on the outer wall of the dispersing tank. The output end of the hydraulic cylinder passes through the bracket and is fixedly connected to a connecting sleeve. A shaft is fixedly connected to the outer wall of the connecting ring, and the connecting sleeve is sleeved on the outer wall of the shaft.

[0011] Preferably, the drive unit includes a support plate installed between two connecting rings and a gear ring fixedly installed on the outer wall of the dispersion tank.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention involves installing a dispersion barrel, controlled by a lifting unit, on a temperature-controlled circulating water cooling tank. The dispersion barrel is driven to rotate by a drive unit, allowing high-chromium balls to be placed inside. The rotation of the dispersion barrel causes the balls to roll, thus pre-treating surface debris and reducing the impact of debris entering the temperature-controlled circulating water cooling tank on the cooling effect. It also facilitates the collection of debris. The dispersion barrel is then controlled to enter the temperature-controlled circulating water cooling tank for secondary cooling. During the cooling process, the continuous rotation of the dispersion barrel keeps the high-chromium balls under dynamic cooling, resulting in more uniform cooling and improved cooling quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides a high-chromium ball cooling device, which includes a temperature-controlled circulating water cooling tank 1. The temperature-controlled circulating water cooling tank 1 has temperature regulation, forced water circulation, and uses heat exchange equipment to dissipate heat from the water. The water temperature of the temperature-controlled circulating water cooling tank 1 in the present invention is between 30-50℃, which reduces the risk of cracking of the high-chromium balls. This is prior art, so it will not be described in detail.

[0026] A support frame 2 is installed on the temperature-controlled circulating water cooling pool 1. A lifting unit 3 is installed on the support frame 2. A dispersion tank 4 is installed on the lifting unit 3. The dispersion tank 4 is used to load high-chromium balls. The lifting unit 3 includes multiple hydraulic cylinders 31 installed on the support frame 2 and two connecting rings 32 sleeved on the outer wall of the dispersion tank 4. The output end of the hydraulic cylinder 31 passes through the support frame 2 and is fixedly connected to a connecting sleeve 34. A shaft 33 is fixedly connected to the outer wall of the connecting ring 32. The connecting sleeve 34 is sleeved on the outer wall of the shaft 33. The output end of the hydraulic cylinder 31 rises, and the connecting sleeve 34, shaft 33 and connecting ring 32 control the rise or fall of the dispersion tank 4, thereby controlling the dispersion tank 4 to enter and exit the temperature-controlled circulating water cooling pool 1. When the dispersion tank 4 is outside the temperature-controlled circulating water cooling pool 1, it is pre-cooled and the debris on the outer wall of the high-chromium balls is cleaned. When the dispersion tank 4 enters the temperature-controlled circulating water cooling pool 1, it is cooled by the coolant in the temperature-controlled circulating water cooling pool 1.

[0027] A drive unit 6 is installed between the lifting unit 3 and the dispersion tank 4. The drive unit 6 is used to drive the dispersion tank 4 to rotate. The drive unit 6 includes a support plate 61 installed between two connecting rings 32 and a gear ring 65 fixedly installed on the outer wall of the dispersion tank 4. The upper surface of the support plate 61 has a through hole 63. A motor 62 is installed on the upper surface of the support plate 61. The output shaft of the motor 62 is equipped with a gear 64 that passes through the through hole 63 and meshes with the gear ring 65. The outer wall of the dispersion tank 4 has multiple sieve holes 5. A collection plate 8 is movably placed on the temperature-controlled circulating water cooling pool 1. When the high-chromium balls are cooled after quenching, the high-chromium balls are poured into the dispersion tank 4 from the end opening. The collection plate 8 is placed on the temperature-controlled circulating water cooling pool 1, and the motor 62 is started. The motor 62 drives the dispersion tank 4 to rotate inside the connecting ring 32 through the gear 64 and the gear ring 65. As the dispersion tank 4 rotates, the high-chromium balls placed inside collide and roll, causing the surface debris to fall off and fall through the sieve holes 5. The high-chromium balls are collected on the collection plate 8 for impurity removal. During the impurity removal process, a fan can be placed at one end of the dispersion tank 4 to accelerate the air circulation inside the dispersion tank 4, thereby achieving pre-cooling of the high-chromium balls. After the high-chromium balls are removed, the collection plate 8 is removed from the temperature-controlled circulating water cooling pool 1. At this time, the lifting unit 3 controls the dispersion tank 4 to descend into the temperature-controlled circulating water cooling pool 1, while the motor 62 remains outside the coolant. The dispersion tank 4 continues to rotate, causing the high-chromium balls in the temperature-controlled circulating water cooling pool 1 to continue rolling, thus fully exchanging heat with the coolant and achieving cooling. This reduces the amount of slag on the surface of the high-chromium balls after quenching entering the temperature-controlled circulating water cooling pool 1 and affecting the heat dissipation effect on the high-chromium balls. It also facilitates the collection and treatment of slag. Furthermore, the high-chromium balls are pre-cooled to a certain temperature before water cooling, avoiding the phenomenon that the high-chromium balls, due to their material properties, will crack when in direct contact with water at high temperatures, exceeding the critical cooling rate. This improves practicality.

[0028] Two connecting sleeves 34 located at one end of the dispersion tank 4 have waist holes 35 on their side walls. The waist holes 35 are fitted onto the outer wall of the shaft 33. The other two connecting sleeves 34 are tightly fitted to the outer wall of the shaft 33, and the shaft 33 is slidably connected to the connecting sleeves 34. After the high-chromium balls are cooled, the dispersion tank 4 is removed from the temperature-controlled circulating water cooling pool 1 using the lifting unit 3. At this time, the height of the connecting sleeves 34 at the output end of the two cylinders 31 located at one end of the dispersion tank 4 in the lifting unit 3 is higher than that of the other two. The two higher connecting sleeves 34 have waist holes 35 on their side walls. The connecting sleeves 34 slide on the outer wall of the shaft 33, thereby tilting the dispersion tank 4. The collecting plate 8 is placed on the temperature-controlled circulating water cooling pool 1 in advance. The tilted dispersion tank 4 will pour out the high-chromium balls inside and fall onto the collecting plate 8, realizing unloading and facilitating use.

[0029] Both ends of the dispersion barrel 4 are equipped with retaining rings 10. The retaining ring 10 near the waist hole 35 is welded to the dispersion barrel 4. At least two bolts 11 are threaded through the other retaining ring 10 and are threaded to the end of the dispersion barrel 4. When the high chromium ball rolls in the dispersion barrel 4, the retaining rings 10 at both ends prevent the high chromium ball from rolling out of the dispersion barrel 4. When the high chromium ball is discharged from the dispersion barrel 4, only one bolt 11 needs to be loosened so that the retaining ring 10 can rotate without obstructing the lower end of the dispersion barrel 4 and thus not block the high chromium ball. At this time, the high chromium ball can roll out of the dispersion barrel 4.

[0030] Multiple pushers 7 are installed inside the dispersion tank 4. When the dispersion tank 4 rotates, the pushers 7 can move the high-chromium balls to a certain height and then fall down, thereby improving the rolling of the high-chromium balls and making it easier for the surface debris to fall off.

[0031] The surface of the collecting plate 8 is inclined, and two side baffles 9 are fixedly connected to the upper surface of the collecting plate 8. The inclined surface of the collecting plate 8 facilitates the sliding of debris and high-chromium balls from the collecting plate 8, and the side baffles 9 prevent debris and high-chromium balls from sliding out along the side of the collecting plate 8, making it easy to collect.
