TECHNICAL FIELD

[0001] The utility model relates to the technical field of part cleaning in the maintenance of oil pressure shock absorber for urban rail vehicles, and particularly relates to a cleaning device utilizing compressed air to disturb water flow. BACKGROUND

[0003] High-pressure cleaning and manual cleaning are generally single-branch cleaning, and especially when the maintenance parts have more oil stains, the cleaning efficiency is low; ultrasonic cleaning is a high-efficiency way, but the cleaning frame needs to be moved up and down to enhance the cleaning effect, and the up-and-down moving speed is usually low, and the cavitation effect of ultrasonic waves is still the main one. Therefore, the ultrasonic cleaning machine usually has a large investment, and the ultrasonic generator has the problem of power reduction over time. SUMMARY

[0004] The utility model aims at providing a cleaning device utilizing compressed air to disturb water flow, which can realize the comprehensive cleaning of soaking and water flow impact when the maintenance shock absorber parts have more oil stains at a lower cost through the principle of using compressed air to disturb water flow.

[0007] When cleaning, the pressure of compressed air is adjusted according to the oil stain condition of the maintenance shock absorber parts, when the compressed air enters the cleaning tank, the disturbance of water flow is generated in the cleaning liquid, the cleaning liquid has a large impact force and generates a large number of bubbles in different directions, the combined action of which produces impact and stripping on the surface oil stains of the parts, and cooperates with the saponification of the cleaning liquid on the oil stains to improve the cleaning effect of the parts.

[0008] In actual application, the cleaning liquid interface of the cleaning tank is provided with an oil blowing pipe, and the oil blowing pipe is used to blow the oil stains floating on the liquid surface to the sewage outlet to avoid the diffusion of the oil stains.

[0009] The side wall of the cleaning tank away from the oil blowing pipe is provided with an oil stain collecting groove.

[0010] Specifically, a heating tube is provided at the bottom of the cleaning tank, and the heating tube is located below the bottom air outlet pipe.

[0011] Furthermore, a mesh screen is provided at the bottom of the cleaning tank, and the mesh screen is located above the bottom air outlet pipe.

[0012] A cleaning method that utilizes compressed air to agitate water flow includes the following steps:

[0013] Alkaline cleaning solution is stored in the cleaning tank;

[0014] The temperature of the cleaning solution is raised to 70-80℃ by heating with a heating element.

[0015] The shock absorber parts are placed in the cleaning frame, and the cleaning frame is placed on the bottom mesh of the cleaning tank;

[0016] The bottom air outlet is opened by adjusting the pressure valve, and air is sprayed upwards into the cleaning fluid to disturb the water flow and create a certain water pressure impact.

[0017] The side air outlet is opened by the pressure regulating valve, and air is sprayed into the cleaning liquid from the side of the cleaning tank. The air outlet is arranged at intervals with the bottom airflow to form a vertical turbulent water flow.

[0018] Under the combined action of alkaline cleaning solution, water temperature, bubbles and water flow, as well as turbulent airflow from different directions, the shock absorber parts are cleaned in all directions.

Both the bottom and side air outlet pipes are compressed air outlets and are equipped with pressure regulating valves. During cleaning, the pressure of the compressed air is adjusted according to the oil stains on the shock absorber parts being inspected. When the compressed air enters the cleaning tank, it generates water flow disturbance in the cleaning fluid. The gas in different directions causes a large impact force on the cleaning fluid and generates a large number of bubbles. Their combined action impacts and peels off the oil stains on the surface of the parts, and, together with the saponification effect of the cleaning fluid on the oil stains, improves the cleaning effect of the parts. Therefore, the cleaning device using compressed air to agitate water flow provided by this utility model achieves comprehensive cleaning of parts at low cost by adding airflow disturbance to the cleaning method of commonly used parts cleaning.

The bottom air outlet pipe 2 and the side air outlet pipe 3 are compressed air outlets and are equipped with pressure regulating valves 7.

[0027] During cleaning, the pressure of compressed air is adjusted according to the oil stains on the shock absorber parts being inspected. When the compressed air enters the cleaning tank, it creates turbulence in the cleaning fluid. The gas in different directions causes a large impact force on the cleaning fluid and generates a large number of bubbles. Their combined action impacts and peels off the oil stains on the surface of the parts. This, combined with the saponification effect of the cleaning fluid on the oil stains, improves the cleaning effect of the parts.

[0034] Under the combined action of alkaline cleaning solution, water temperature, bubbles and water flow, as well as turbulent airflow in different directions, the shock absorber parts are cleaned in all directions. After cleaning, the oil stains floating on the water surface can be quickly blown into the oil collection tank 4 through the oil blowing pipe 5.

[0035] Compared with the prior art, the cleaning device that utilizes compressed air to agitate water flow as described in this embodiment of the invention has the following advantages:

During cleaning, the pressure of the compressed air is adjusted according to the oil stains on the shock absorber parts being inspected. When the compressed air enters the cleaning tank, it generates water flow disturbance in the cleaning liquid.

[0038] Among them, such as Figure 1 and Figure 2 As shown, an oil collection tank 4 can be provided on the side wall of the cleaning tank 1 away from the oil blowing pipe 5.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, a heating tube 6 can be installed at the bottom of the cleaning tank 1, and the heating tube 6 is located below the bottom air outlet pipe 2. The water temperature of the cleaning liquid is raised to 70-80℃ after being heated by the heating tube 6, so as to effectively improve the saponification effect.

[0040] Furthermore, such as Figure 1 and Figure 2As shown, a partition net 8 can be provided at the bottom of the cleaning tank 1, and the partition net 8 is located above the bottom air outlet pipe 2, so that the shock absorber parts can be placed in the cleaning frame and the cleaning frame is placed on the bottom partition net 8 of the cleaning tank 1 for subsequent omnidirectional cleaning.
