Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a water-cooled continuous casting roll bearing housing cleaning and testing device. Background Technology

[0002] The continuous casting roll bearing housing is cooled by circulating cooling water to prevent lubrication medium failure and subsequent bearing housing malfunction. However, long-term cooling water circulation can cause a large amount of scale to accumulate on the inner wall of the bearing housing, which can easily affect the flow rate of the circulating water, greatly reducing the cooling effect and leading to bearing damage, continuous casting roll failure, and other problems.

[0003] The existing cleaning method is kerosene cleaning solution, which has the following disadvantages: 1. High cost; 2. Damage to the environment and human body; 3. Flammability is not safe; 4. Incomplete cleaning. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water-cooled continuous casting roll bearing housing cleaning and testing device and method, which improves the cleaning rate and effect, and extends the service life of the equipment.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A water-cooled continuous casting roll bearing housing cleaning and testing device includes an ultrasonic cleaning device and a cleaning and testing platform. The cleaning and testing platform includes a workbench, with a cleaning inlet pipe and a cleaning return pipe located below the workbench. Several connecting base plates are connected to the upper surface of the workbench, and a pressing device is provided between two connecting base plates. The connecting base plates are provided with inlet and outlet ports that connect to the water-cooling channels of the continuous casting roll bearing housing. The cleaning inlet pipe and the cleaning return pipe are respectively connected to the inlet and outlet ports on each connecting base plate through inlet and return branch pipes. The inlet end of the cleaning inlet pipe and the outlet end of the cleaning return pipe are respectively connected to a pipeline valve, a pressure pump, a flow meter, and a pressure gauge.

[0007] The ultrasonic cleaning device includes a cleaning tank, the bottom of which is connected to a water pump via an outlet pipe, the water pump is connected to a filter, the filter is connected to a heater, the heater is connected to the bottom of the cleaning tank via a return water pipe, and several transducers are distributed on the bottom surface of the cleaning tank. The transducers are electrically connected to an ultrasonic generator, which is powered by a power source.

[0008] The thickness of the connecting base plate is 15-25mm.

[0009] The connecting base plate is embedded in the groove at the bottom of the continuous casting roll bearing seat.

[0010] The pressing device includes a pressure plate, a screw, and a fastening nut. The bottom end of the screw is detachably connected to the workbench via a thread, the pressure plate is movably sleeved on the screw, and the top end of the screw is fitted with a fastening nut.

[0012] A method for using a water-cooled continuous casting roll bearing housing cleaning and testing device includes:

[0013] 1) Use high-pressure water to flush the continuous casting roll bearing housing to remove surface oil and scale;

[0014] 2) After rinsing, the continuous casting roll bearing housing is placed in the cleaning tank of the ultrasonic cleaning device and soaked in the cleaning solution. The temperature of the cleaning tank is controlled at 80-90℃, and the ultrasonic generator is turned on at the same time. The continuous casting roll bearing housing is soaked in the cleaning tank for 3-6 hours.

[0015] 3) After soaking, rinse the surface of the continuous casting roll bearing housing with low-pressure clean water to remove residual cleaning solution and impurities;

[0016] 4) The continuous casting roll bearing housing is dried;

[0017] 5) After drying, the continuous casting roll bearing housing is hoisted to the workbench of the cleaning and testing platform. The continuous casting roll bearing housing is installed on the connecting base plate and fixed with the crimping device to ensure that the water cooling channel of the continuous casting roll bearing housing is sealed and connected to the water inlet and outlet interfaces on the connecting base plate.

[0018] 6) Open the valves of the cleaning inlet and return water pipes to flush the water cooling channel of the continuous casting roll bearing housing. When the flow rates of the cleaning inlet and return water pipes are consistent, close the valves.

[0019] 7) Start the pressure pumps on the cleaning inlet and return water pipes, with a pressure of 1.2 to 1.5 MPa, and maintain the pressure for 30 to 40 minutes;

[0020] 8) Inspect the continuous casting roll bearing housing for leaks, and repair any leaks by welding.

[0021] 9) Inspect the continuous casting roll bearing housings without leaks for wear, cracks, and deformation. Perform flaw detection on the qualified continuous casting roll bearing housings.

[0022] In step 1), the pressure of the high-pressure water is 2.0 to 3.5 MPa.

[0023] In step 2), the cleaning solution is prepared by mixing descaling agent and water at a mass ratio of (1-1.5):10.

[0024] The pressure of the low-pressure water in step 3) is 0.2 to 1.5 MPa.

[0025] In step 4), the drying method is to use hot air drying or vacuum drying.

[0026] Compared with existing technologies, the beneficial effects of this invention are:

[0027] 1. Improve cleaning effect: Ensure that the continuous casting roll bearing housing is thoroughly cleaned to remove dirt, grease, metal shavings and other impurities, so as to ensure its normal operation and extend its service life.

[0028] 2. Improve work efficiency: Compared with manual cleaning, specialized cleaning equipment can complete cleaning tasks more quickly and efficiently, saving time and labor costs.

[0029] 3. Ensure consistent cleaning quality: The cleaning equipment provides standardized cleaning processes and parameters, ensuring stable and reliable cleaning quality for each cleaning session.

[0030] 4. Reduce errors and risks associated with manual operation: Avoid omissions or improper operations that may occur during manual cleaning, thereby reducing the risk of equipment damage.

[0031] 5. Improved working environment: Automatic or semi-automatic cleaning equipment can reduce workers' exposure to cleaning agents and dirt, helping to protect workers' health and safety.

[0032] 6. Maintaining equipment precision: Clean bearing housings help maintain the precision and operational stability of continuous casting rolls, thereby improving product quality.

[0033] 7. Reduce maintenance costs: Regular and effective cleaning can reduce wear and failure of bearing housings, thereby reducing maintenance and replacement costs. Attached Figure Description
