Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the embodiment of the present invention provides a bearing forging heat treatment device for wind power generation equipment and a process thereof, comprising a treatment pool 1, a cleaning chute 2 is provided on one side of the top of the treatment pool 1, a distribution type air supply component 3 is provided on both sides of the treatment pool 1, a lifting component 4 is fixedly provided on both sides of the treatment pool 1, the distribution type air supply component 3 inputs pressurized air into the lifting component 4, a self-cleaning component 5 is provided inside the treatment pool 1, both sides of the self-cleaning component 5 are fixedly connected to the lifting component 4, and the lifting component 4 drives the self-cleaning component 5 to move up and down in the treatment pool 1;

[0034] The self-cleaning assembly 5 includes a carrier 51, a rotating roller 52, a conveyor belt 53, a filter hole 54, a power unit 55, an intermediate gear 56 and a driven gear 57. The rotating roller 52 is rotatably installed on both sides of the carrier 51, the conveyor belt 53 is wound around the outer side of the rotating roller 52, and the driven gear 57 is fixedly sleeved on the intermediate shaft of a rotating roller 52. The power unit 55 drives the driven gear 57 to engage and rotate through the intermediate gear 56.

[0035] Embodiment 1: After the bearing workpiece is removed from the treatment pool 1, the air pump 31 in the distributed air supply component 3 is started, so that the pressurized air is input into the lifting component 4 through the control valve 32, and the bent rod 43 is pushed upward in the fixed sleeve 41, so that the bent rod 43 drives the connecting plate 101 to move upward, thereby driving the carrier 51 to move upward, so that the self-cleaning component 5 is moved out of the liquid surface, and the particulate impurities suspended and floating in the solution are lifted out of the liquid surface, and the liquid penetrates downward through the filter hole 54 and flows back into the treatment pool 1, the power unit 55 is started and drives the intermediate gear 56 to rotate, so that the driven gear 57 rotates, thereby rotating the rotating roller 52 and rotating the conveyor belt 53, so that the impurity particles filtered and collected on the conveyor belt 53 slide toward the cleaning chute 2, and automatic cleaning is completed; when further clearing is needed, the control valve 32 is actuated, and the hose 34 is grabbed, so that it is blown toward the filter hole 54 on the conveyor belt 53 and cleared by pneumatic force.

[0036] Firstly, by utilizing the distributed air supply component 3 to provide pressurized air and acting on the lifting component 4, the lifting component 4 drives the self-cleaning component 5 to move upward. When the self-cleaning component 5 moves upward to the cleaning chute 2, the internal impurities are filtered and the filtered material is retained on the conveyor belt 53. With the self-rotating conveyor belt 53, the impurities and particles gathered on the top are quickly separated. The actual operation is simple and the separation speed is fast. After the quenching of a group of bearings is completed, the rapid cleaning operation is completed as it moves upward to avoid a large amount of impurities remaining in the cooling medium to affect the quenching quality, and the use effect is good.

[0037] In addition, by reusing the air supply effect of the distributed air supply component 3, when the gas is input into the hose 34, the self-cleaning component 5 is moved upward, and the hose 34 is directed toward the filter hole 54 on the conveyor belt 53. The pressurized air is blown out and acts on the filter hole 54 to clear the blockage in the filter hole 54. Autonomous clearing is completed without adding other power equipment.

[0038] Among them, the conveyor belt 53 moves in the direction of cleaning the chute 2, an assembly cavity 8 is opened inside the carrier 51, the intermediate gear 56 and the driven gear 57 are located in the assembly cavity 8, the power unit 55 is installed inside the carrier 51, the power unit 55 includes a motor and a driving gear, the driving gear is meshed and connected with the intermediate gear 56, the filter holes 54 are distributed in an array on the outer surface of the conveyor belt 53, and a water seepage groove is opened on the front of the carrier 51.

[0039] By controlling the moving direction of the conveyor belt 53 and coordinating with the arrangement of the cleaning chute 2, when the conveyor belt 53 moves up and contacts, the debris and impurities collected on the top are effectively guided to be automatically separated, the power unit 55 provides rotational power, the intermediate gear 56 is assembled in the assembly cavity 8 through the internal rotating shaft and bearing, and the seepage groove and filter hole 54 ensure stability to separate the coolant.

[0040] Among them, the distributed air supply component 3 includes an air pump 31, a control valve 32, a No. 1 pipe 33 and a hose 34. The air outlet end of the air pump 31 is fixedly connected to the control valve 32, one air outlet end of the control valve 32 is fixedly connected to the lifting component 4, and the other two air outlet ends of the control valve 32 are respectively connected to the No. 1 pipe 33 and the hose 34.

[0041] The distributed air supply assembly 3 provides air pressure, which provides driving force on the one hand and direct blowing and cleaning on the other hand.

[0042] Among them, the lifting assembly 4 includes a fixed sleeve 41, a movable plate 42, a bent rod 43 and a spring 44. The fixed sleeve 41 is fixed to the side of the treatment tank 1 through a bottom block. The movable plate 42 is slidably sleeved in the treatment tank 1 and fixedly connected to the carrier 51. One end of the bent rod 43 is fixedly connected to the movable plate 42 and the other end is movably sleeved in the fixed sleeve 41. A section of the spring 44 is fixed in the fixed sleeve 41 and the other end is fixedly connected to the bent rod 43. A slide groove 6 is opened on the inner wall of the treatment tank 1, and the inner surface of the slide groove 6 is slidably sleeved with the movable plate 42.

[0043] The lifting component 4 realizes the lifting and lowering of the self-cleaning component 5 immersed in the treatment tank 1, and the movable plate 42 slides in the slide groove 6 to ensure that the upper part is blocked while lifting and lowering to prevent foreign particles from being transferred to the bottom of the self-cleaning component 5 through the slide groove 6.

[0044] Among them, a cooling mechanism 7 is provided inside the treatment pool 1, and the cooling mechanism 7 includes a cooling water pipe. A cleaning plate 9 is slidably sleeved on the outer side of the cooling water pipe. The cleaning plates 9 are arranged in an array on the outer side of the cooling water pipe. A linkage component 10 is fixedly connected to the side of the cleaning plate 9. One end of the linkage component 10 passes through the treatment pool 1 and extends to the outside. A connecting pipe 11 is fixedly connected between the linkage component 10 and the distributed air supply component 3. One end of the connecting pipe 11 is sealed and fixedly connected to the No. 1 pipe 33.

[0045] By utilizing the cooling mechanism 7 to realize continuous cooling treatment, the liquid in the treatment pool 1 is kept cooled, and the cleaning plate 9 completes surface cleaning when moving horizontally, thereby ensuring the heat exchange effect.

[0046] Among them, the linkage assembly 10 includes a connecting plate 101, a pull rod 102, a side tube 103 and a spring 104.

[0047] When pressurized air is inputted into the linkage assembly 10, the cleaning plate 9 is pushed to move horizontally, thereby completing the pushing process. The elasticity of the spring 2 104 facilitates automatic reset when the air pressure push is removed.

[0048] Example 2: When it is necessary to clean the dirt on the surface of the cooling water pipe, keep the air pump 31 started and operate the control valve 32 so that the gas is input into the No. 1 pipe 33, and then the gas is input into the linkage assembly 10 through the connecting pipe 11, pushing the pull rod 102 to move horizontally along the side pipe 103, thereby driving the cleaning plate 9 to slide, so that the dirt on the surface of the cooling water pipe is cleaned.

[0049] First, by reusing the gas supply effect of the distributed gas supply component 3, the gas is input into the linkage component 10 in conjunction with the connecting pipe 11, and the pull rod 102 drives the cleaning plate 9 to move horizontally. Multiple groups of cleaning plates 9 slide along the outer surface of the cooling water pipe to frictionally clean the scale on the outer side to avoid surface dust accumulation causing an increase in wall thickness, thereby improving the heat exchange effect, maintaining the temperature of the cooling medium in the quenching pool stable, avoiding excessive temperature after continuous quenching treatment, and ensuring an effective quenching process.
