Description

Technical Field

[0001] The utility model relates to the technical field of a mixing and exhausting device for hydraulic oil, in particular to a mixing and exhausting device for hydraulic oil. Background Art

[0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, corrosion prevention, rust prevention, and cooling in hydraulic systems.

[0003] In the prior art, when hydraulic oil is flowing, gas is likely to enter the pipeline. Air cannot dissolve in hydraulic oil. After gas enters the hydraulic pipeline, it will gather into air masses in the pipeline. When the hydraulic oil mixed with gas masses reaches the hydraulic pump, it is easy to burn the hydraulic pump. In addition, when the hydraulic oil mixed with air masses flows in the hydraulic pipeline, it is easy to impact the pipeline.

[0004] Therefore, a device is needed to evenly discharge air masses in hydraulic oil to solve the problem that the air masses in the hydraulic oil easily cause the hydraulic pump to burn out. Utility Model Content

[0005] The purpose of the utility model is to provide a mixing and exhausting device for hydraulic oil to solve the problems raised in the above background technology.

A second exhaust filter is provided at the bottom of the first exhaust filter, and the first exhaust filter is inclined to both sides. The hydraulic oil can slowly slide down from the inclined surface of the second exhaust filter and evenly drip from the inclined mesh opening of the second exhaust filter to be exhausted, thereby performing the second layer of exhaust.

[0009] Preferably, a baffle is provided at the connection between the first exhaust port, the second exhaust port and the exhaust pipe, and the baffle is inclined. The baffle can block the hydraulic oil flowing into the first exhaust port and the second exhaust port to prevent the hydraulic oil from flowing into the exhaust pipe.

[0010] Preferably, the bottom of the exhaust pipe is connected to a return pipe, the other end of the return pipe is plugged into the bottom of the exhaust device, and a third exhaust filter is provided at the top of the return pipe. The third exhaust filter can exhaust the hydraulic oil flowing into the return pipe, and then flow into the exhaust device from the bottom of the return pipe.

When the hydraulic oil is exhausted, the hydraulic oil enters the exhaust device from the oil inlet pipe, and the hydraulic oil is exhausted for the first layer through the first exhaust filter screen arranged on the top of the exhaust device. The exhausted air is discharged into the exhaust pipe from the first exhaust port plugged in the side of the exhaust device. After that, the hydraulic oil passes through the second exhaust filter screen. The second exhaust filter screen is inclined on both sides. The second exhaust filter screen can evenly spread the hydraulic oil through the inclined surface.

When the hydraulic oil flow rate is too large and the baffle plate does not block it completely, the hydraulic oil flowing into the exhaust pipe can flow back to the exhaust device along the return pipe. A third exhaust filter is arranged at the top of the return pipe. The third exhaust filter exhausts the hydraulic oil flowing into the exhaust pipe to prevent the unexhausted hydraulic oil from flowing into the exhaust device along the return pipe, resulting in incomplete exhaust. An exhaust port is arranged at the top of the exhaust pipe. The air discharged into the exhaust pipe from the first exhaust port and the second exhaust port is discharged from the exhaust port. Support columns are arranged around the top of the exhaust port, and a dustproof net is supported on the support columns.
