Description

Technical Field

[0001] This utility model relates to a flywheel blackening process, and more specifically, to a production line for flywheel blackening treatment. Background Technology

[0002] The blackening process for flywheels creates a black protective film that effectively isolates air and moisture, reducing the erosion of metal parts by corrosive substances and extending the flywheel's service life. Existing flywheel blackening production lines include overhead cranes and sequentially arranged components such as a rough washing machine, a fine washing machine, a degreasing tank, a first rinsing tank, a blackening tank, a second rinsing tank, a passivation tank, an automatic air blowing chamber, a rust-preventive oil tank, and an oil blowing chamber. The current flywheel blackening process involves using an overhead crane to move the flywheel into each tank for treatment. However, in the existing process, the blackening solution in the blackening tank is essentially static, and the concentration of the blackening solution varies at different locations. The temperature of the blackening solution is also unstable. The overhead crane only moves the flywheel up, down, or horizontally within the blackening tank. Since each batch of flywheels has a different and complex structure, the blackening treatment effect on some parts of the flywheel is often poor, leading to problems such as overheating, whitening, and spots on the flywheel surface, failing to meet processing requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a production line for flywheel blackening treatment, which addresses the shortcomings of the existing technology and solves the technical problem that the blackening liquid has poor fluidity and unstable temperature, resulting in poor flywheel blackening treatment effect.

[0006] Furthermore, the first motor is a variable frequency motor.

[0007] Furthermore, the second turbulence structure includes a water pump, a first pipe, and a second pipe. The water pump is fixedly installed above the side wall of the blackening tank.

The outlet of the water pump is fixedly connected to one end of the second pipe, and the other end of the second pipe extends into the blackening tank. Both the water pump and the first motor are electrically connected to the controller.

[0008] Furthermore, filters are installed at one end of both the first pipe and one end of the second pipe.

[0009] Furthermore, the heating structure includes a steam generator and a corrosion-resistant coil. The steam generator is placed outside the blackening tank, and the coil is fixedly installed on one side of the blackening tank. The steam generator's outlet is fixedly connected to one end of the coil, and the steam generator's inlet is fixedly connected to the other end of the coil.

Detailed Implementation

[0015] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention. See Figures 1-3 The present invention discloses a production line for flywheel blackening treatment, including a blackening tank 7. The blackening tank 7 is provided with a first turbulence structure and a second turbulence structure to improve the fluidity of the blackening liquid. A heating structure is provided on one side of the blackening tank 7, and a cleaning structure for cleaning suspended impurities and oil stains in the blackening liquid is also provided on one side of the blackening tank 7.

[0016] like Figure 2-3 As shown, the first turbulence structure includes multiple first motors 101 and multiple impellers 103. Multiple first motors 101 are installed on the outside of the blackening pool 7. Multiple rotating rods 104 are rotatably installed on both sides inside the blackening pool 7. One end of the rotating rod 104 passes through the side wall of the blackening pool 7 and is fixedly connected to the drive end of the first motor 101. The other end of the rotating rod 104 is fixedly installed with an impeller 103.

[0017] The first motor 101 is a variable frequency motor. By setting the first motor 101 as a variable frequency motor, the speed of the impeller 103 can be flexibly adjusted, thereby efficiently adjusting the turbulent flow velocity of the blackening liquid in the blackening tank 7.

[0018] The second turbulence structure includes a water pump 102, a first pipe 105, and a second pipe 106. The water pump 102 is fixedly installed above the side wall of the blackening tank 7. The inlet of the water pump 102 is fixedly connected to one end of the first pipe 105, and the other end of the first pipe 105 extends into the blackening tank 7. The outlet of the water pump 102 is fixedly connected to one end of the second pipe 106, and the other end of the second pipe 106 extends into the blackening tank 7. The water pump 102 and the first motor 101 are both electrically connected to the controller.

[0019] A filter screen 107 is installed at one end of the first pipe 105 and one end of the second pipe 106. This prevents impurities in the blackening solution from entering the water pump 102 and causing damage to the water pump 102.

[0020] Both the first and second turbulence structures can improve the fluidity of the blackening solution in the blackening pool, making the concentration of the blackening solution more uniform, so that the complex flywheel can have a better blackening treatment effect.

[0021] The heating structure includes a steam generator 110 and a corrosion-resistant coil 111. The steam generator 110 is placed outside the blackening tank 7, and the coil 111 is fixedly installed on one side of the blackening tank 7. The steam outlet of the steam generator 110 is fixedly connected to one end of the coil 111, and the water inlet of the steam generator 110 is fixedly connected to the other end of the coil 111. A control valve 112 is provided at the end of the coil 111 near the steam outlet of the steam generator 110, and a steam trap 113 is provided at the end of the coil 111 near the water inlet of the steam generator 110. Both the steam generator 110 and the control valve 112 are electrically connected to a controller. The control valve 112 is used to control the flow of steam in the coil 111, and the steam trap 113 is used to continuously discharge condensate from the steam-heated pipe into the water inlet of the steam generator 110.

[0022] A temperature sensor 114 is installed in the blackening tank 7, and the temperature sensor 114 is electrically connected to the controller. The temperature sensor 114 outputs the real-time temperature signal of the blackening liquor in the blackening tank 7, and inputs the real-time temperature signal of the blackening liquor into the controller, which operates the control valve 112 according to the real-time temperature of the blackening liquor. In this embodiment, the temperature sensor is an OMEGApt100 temperature sensor, which is corrosion-resistant and highly accurate.

[0023] The cleaning structure includes an electric slide rail 120 and an oil filter screen 121. The electric slide rail 120 is fixedly installed on the upper inner side of the blackening tank 7. The slider 122 of the electric slide rail 120 is threadedly connected to the connecting rod 123. The oil filter screen 121 is fixedly installed on the connecting rod 123. The electric slide rail 120 is electrically connected to the controller. The cleaning structure removes suspended impurities, oil, and sediment from the blackening liquid, thereby keeping the blackening liquid clean and ensuring the blackening effect of the flywheel. When the contaminants in the oil filter screen 121 reach a certain amount, the oil filter screen 121 can be replaced and cleaned by disassembling the connecting rod 123.

[0024] The working principle of this utility model is as follows: Hang the flywheel 1 to be processed on the hook of the overhead crane 2 above the production line. Start the rough washing machine 3, fine washing machine 4, steam generator 110, water pump 102 and first motor 101. Control the overhead crane 2 to move the flywheel 1 to be processed to the rough washing machine 3 for rough washing. Then move the flywheel 1 after rough washing into the fine washing machine 4 for fine washing. Next, move the flywheel 1 after fine washing into the degreasing tank 5 for degreasing. Then move the degreased flywheel 1 into the first rinsing tank 6 for the first rinsing.

[0025] The overhead crane 2 moves the flywheel 1, which has been rinsed for the first time, to the blackening tank 7 for blackening treatment. During the blackening treatment, the blackening liquid flowing into the first pipe 105 is discharged from the second pipe 106 through the water pump 102, thereby accelerating the flow of the blackening liquid in the blackening tank 7. The drive end of the first motor 101 rotates, driving the impeller 103 to rotate, which also accelerates the flow of the blackening liquid in the blackening tank 7, so as to make the concentration of the blackening liquid in the blackening tank 7 more uniform.

[0026] The controller acquires the real-time temperature signal of the blackening liquor through a temperature sensor. When the real-time temperature of the blackening liquor is lower than the preset blackening treatment temperature, the controller opens the control valve 112 to introduce the steam generated by the steam generator 110 into the coil 111, thereby increasing the temperature of the coil 111. The coil 111 heats the blackening liquor to raise its real-time temperature to the blackening treatment temperature. When the real-time temperature of the blackening liquor is equal to or greater than the blackening treatment temperature, the control valve 112 is closed.

[0027] When a large amount of impurities, oil, and sediment are observed suspended in the blackening solution, the electric slide rail 120 is activated. The slider 122 of the electric slide rail 120 begins to move, which in turn moves the connecting rod 123 and the oil filter screen 121. The oil filter screen 121 collects the impurities, oil, and sediment to reduce their accumulation in the blackening solution.

[0028] The flywheel 1 after blackening treatment is then moved to the passivation tank 9 for passivation treatment. After passivation treatment, the flywheel 1 is moved to the automatic air blowing chamber 10, where the surface of the flywheel 1 is dried. Then, the flywheel 1 after surface drying is moved to the anti-rust oil tank 11 for oil run-out treatment. Finally, the flywheel 1 after oil run-out treatment is moved to the oil blowing chamber 12 for oil blowing treatment. Finally, the flywheel 1 after oil blowing treatment is taken off the production line.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
