[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are generally composed of an outer ring, an inner ring, and steel balls. During the heat treatment of steel balls, in order to change the internal structure and properties of the steel balls and improve their strength, hardness, wear resistance, fatigue strength, and toughness, it is usually necessary to heat the steel balls to a certain temperature and place them in a quenching liquid for chilling quenching.

[0003] The existing steel ball quenching pool also has some shortcomings when in use. At present, most quenching pools have steel balls falling directly into the quenching liquid. Due to the high temperature inside the steel ball, the quenching liquid will boil in an instant, causing the high-temperature quenching liquid to splash out, which not only makes the steel ball surface quenched unevenly and the hardness uneven, but also causes a waste of quenching liquid, and even splashes onto workers, posing a certain risk.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] See also Figure 1-2 The present embodiment relates to a steel ball quenching pool, comprising a pool body 1, wherein the pool body 1 is provided with a spiral guide groove 11 which leads from the upper opening of the pool body 1 to the bottom, the bottom is provided with a discharge port 12, and the discharge port 12 is provided with a valve body 2.

[0021] Specifically in this embodiment, steel balls heated to a certain temperature are added into the sealed pool body 1 through the hopper at the top opening of the pool body 1, and the added steel balls roll around the spiral guide groove 11 to the pool bottom discharge port 12. When the number of steel balls at the pool bottom discharge port 12 reaches a certain number, they will be discharged through the valve body 2 below the pool bottom discharge port 12. The steel balls gradually fall in the spiral guide groove 11, and are fully in contact with the quenching liquid during the rolling and descending process of the steel balls, so that the quenching is uniform and the hardness is uniform, thereby ensuring the quenching quality of the steel balls and improving the quenching stability. The sealing of the pool body 1 can prevent the quenching liquid from splashing and avoid wasting the quenching liquid.

[0022] See also Figure 3-4 The valve body 2 includes a valve seat 21, a motor 22 and a valve plate 23. The valve seat 21 is fixed to the bottom of the pool body 1 through a flange 24 structure. The motor 22 is fixed to the bottom of the valve seat 21 and the valve plate 23 is fixed through a drive shaft 25. The valve plate 23 is rotatably arranged at the bottom of the pool body 1. The valve plate 23 is provided with a valve port 26 adapted to the discharge port 12 of the pool body 1. The valve seat 21 is provided with a conical arc plate arranged directly below the discharge port 12. The valve seat 21 is provided with an opening on one side of the conical arc plate, and is isolated by the conical arc plate on the other side to form an independent cavity. The motor 22 is arranged in an independent cavity. When the number of steel balls in the discharge port 12 is full, the motor 22 will drive the valve plate 23 and the conical arc plate to rotate, and the valve port 26 of the valve plate 23 rotates to the discharge port 12 adapted thereto. The discharge port 12 opens, and the bearing steel balls and the quenching liquid are sent out. The steel balls roll out on the conical arc plate to complete the discharge. This type of valve body 2 can prevent a large amount of bearing steel balls from accumulating and jamming, and realize batch quenching. The valve seat 21 is connected to the bottom of the quenching tank 1 through the flange 24 structure, which is easy to disassemble. In addition, the motor 22 is arranged in an independent cavity formed by a conical arc plate, which can prevent the quenching liquid from entering the motor 22 and causing damage to the motor 22.

[0023] See also Figure 5The upper side of the upper opening of the pool body 1 is provided with a gas processing component 3, and the gas processing component 3 includes an exhaust device 31, an exhaust pipe 32 and an activated carbon filter 33. The top of the pool body 1 is provided with an opening, and the exhaust device 31 is connected through the exhaust pipe 32. The activated carbon filter 33 is arranged in the exhaust pipe 32. An activated carbon filter 33 for adsorbing exhaust gas is arranged in the exhaust pipe 32. During the quenching process, the harmful gas generated by the steel ball and the quenching liquid flows through the exhaust pipe 32 under the action of the exhaust device 31, and the activated carbon filter 33 in the exhaust pipe 32 adsorbs and filters the harmful gas and then discharges it to the outside. It can prevent harmful gases from being inhaled into the human body, reduce the emission of harmful gases, and prevent air pollution.

[0024] See also Figure 6 The spiral guide groove 11 is spirally arranged on the central column 13, and a baffle 14 is arranged at the bottom of the spiral guide groove 11. The steel balls roll to the discharge port 12 through the spiral guide groove 11, and the steel balls gather at the discharge port 12 under the action of the baffle 14. The baffle 14 makes the steel balls gather above the discharge port 12, which is convenient for discharging, prevents the steel balls from being stuck, improves the stability of the steel ball discharging, and ensures the quenching efficiency.

[0025] See also Figure 2 A conveying line 4 is arranged at the lower side of the valve port 26. The conveying belt of the conveying line 4 adopts a filter belt 41. A quenching liquid recovery pool is arranged at the lower side of the filter belt 41. After the steel balls and the quenching liquid are discharged through the valve body 2, they fall onto the conveying belt of the conveying line 4. The quenching liquid flows into the lower quenching liquid recovery pool 42 through the filter belt 41. The steel balls are discharged under the action of the conveying belt. The conveying line 4 can separate the steel balls from the quenching liquid conveniently and quickly, speed up the quenching progress, and improve the quenching efficiency. The impurities generated during the contact between the quenching liquid and the steel balls will be adsorbed on the filter screen. The filter screen can be replaced for cleaning to prevent the impurities from accumulating inside the pool body 1.

[0026] The quenching liquid recovery tank 42 is connected to the tank body 1 through the circulation pump pipeline 5. The quenching liquid after quenching in the tank body 1 is stored in the quenching liquid recovery tank 42. The circulation pump pipeline 5 circulates the quenching liquid in the quenching liquid recovery tank 42 to the tank body 1 for continued quenching under the action of the circulation pump 51. The circulation pump pipeline 5 can avoid the waste of quenching liquid and can circulate the quenching liquid.

[0027] See also Figure 7, the circulation pump pipeline 5 is provided with a control valve 53 on the outside and a filter adsorption filter element component 52 on the inside. The control valve 53 can open or close the circulation pump pipeline 5 according to production needs, the internal adsorption filter element component 52 can filter and adsorb impurities generated by quenching the steel ball in the quenching liquid, the control valve 53 can conveniently control the liquid level of the quenching liquid, the adsorption filter element component 52 can replace the filter element material (for example, using an activated carbon filter element, etc.) as needed, and the adsorption filter element component 52 prevents impurities from entering the circulation pump 51 and causing damage to the equipment, thereby improving the equipment operation stability.
