Description

Technical Field

[0001] The utility model belongs to the field of electric power oil, in particular to an oil filtering device, and more particularly to an oil filtering device with an automatic exhaust and moisture-proof air intake device. Background Art

[0002] Oil filtration equipment is crucial in power systems, as it improves the quality of oil used in power plants and ensures the safe and stable operation of power plant units. Traditional oil filtration equipment is generally composed of an oil pump and a filter tank. During the use of the oil filtration equipment, gas often accumulates in the filter tank due to various reasons, such as dissolved gas or air mixed in during the filtration process. As the oil filtration equipment operates for a long time, the air in the tank has a negative impact on the oil filtration effect, reducing the oil filtration efficiency and even damaging the equipment. Therefore, it is very important to develop a device with automatic exhaust and moisture-proof air intake for oil filtration equipment.

[0003] In order to ensure that the gas in the filter tank of the oil filter equipment is emptied, the existing traditional oil filter equipment is equipped with a manual valve on the upper part of the tank. The valve must be manually opened to exhaust the gas during the operation of the oil filter equipment, which not only consumes time and manpower, but may also affect the oil filtering effect due to improper operation.

[0004] The manual exhaust process is relatively slow because the opening of the exhaust valve needs to be carefully controlled to avoid excessive exhaust that may cause oil spraying or other unexpected situations. It is necessary to pay attention to the exhaust effect at all times. The exhaust operations of different people may result in differences in the degree and effect of exhaust. Utility Model Content

[0021] See also Figure 1 The present invention provides an oil filter device comprising a tank body and an exhaust port 9 disposed on the top of the tank body. Furthermore, the present invention comprises an inductive exhaust mechanism disposed within the tank body; the tank body is connected to the exhaust port 9 via the inductive exhaust mechanism. The present invention utilizes the inductive exhaust mechanism to directly exhaust gas from the tank body, thereby avoiding the tedious and labor-intensive manual operation, reducing interference of gas with the oil filtration process, and improving oil filtration efficiency.

[0022] Among them, for example, see Figure 1 The inductive exhaust mechanism adopted by the present invention includes a gas passage tube, a float 2, a limit indicating component 4, a proximity switch 5 and a solenoid valve 6; the solenoid valve 6 is arranged on the gas passage tube; the gas inside the tank body is connected to the exhaust port 9 through the gas passage tube and the solenoid valve 6; the ball diameter of the float 2 is larger than the inner diameter of the gas passage tube; the float 2 is connected to the limit indicating component 4 and is placed on the upper surface of the oil in the tank body; the limit indicating component 4 extends into the gas passage tube and moves along the axial direction of the gas passage tube; the outer diameter of the limit indicating component 4 is smaller than the inner diameter of the gas passage tube; the proximity switch 5 is arranged on the movement trajectory of the limit indicating component 4 along the axial direction of the gas passage tube; the proximity switch 5 is electrically connected to the solenoid valve 6.

[0023] When the utility model is in use, especially when the oil filter equipment is running, oil begins to flow into the tank body, and the gas in the tank body directly gathers at the top of the tank body. At this time, the gas bypasses the float 2 and enters the gas passage pipe, and is discharged upward from the gas passage pipe, and continues to discharge the excess gas in the tank body through the solenoid valve 6. When the oil filter tank is about to be filled with oil, the oil rises and contacts the float 2, causing the float 2 to continue to rise with the oil, causing the limit indicator component 4 to move upward. When the float 2 is close to or squeezed against the bottom of the gas passage pipe, the limit indicator component 4 is just close to the proximity switch 5, causing the proximity switch 5 to operate, immediately giving a signal to the solenoid valve 6, and the solenoid valve 6 is closed to end the exhaust work; when the oil filter equipment is operating normally and gas appears in the oil filter tank (generally, the oil to be filtered is impure and has gas mixed in), the oil drops, causing the float 2 to drop, causing the limit indicator component 4 to move downward, causing the proximity switch 5 to operate, giving a signal to the solenoid valve 6, and the solenoid valve 6 is opened to perform exhaust work. After the oil in the tank of the oil filter equipment is full, the exhaust work is ended; when the oil filter equipment stops running, because the solenoid valve 6 is associated with the oil pump of the oil filter equipment, the solenoid valve 6 is always in the closed state, and no operation or judgment is performed.

[0024] To prevent the oil level in the tank from dropping and causing the limit indicator component 4 connected to the float 2 to also drop, particularly from detaching from the gas passage, the inductive exhaust mechanism employed in this invention includes a limit base 1 disposed within the tank. The limit base 1 is generally annular, and its inner diameter is smaller than the diameter of the float 2. The limit base 1's restraining action prevents the float 2 from further descending even if the oil level in the tank drops, ensuring stable operation the next time the oil level rises.

[0025] In order to prevent the float 2 from squeezing the bottom of the gas passage tube, resulting in a gap between the two and causing poor sealing, the induction exhaust mechanism adopted by the present invention also includes a float sealing gasket 3 on the upper part of the float 2; the float 2 is squeezed to the bottom of the gas passage tube through the float sealing gasket 3.

[0026] For example, the limit indicator component 4 employed in the present invention is a metal block or sheet; the proximity switch 5 is an inductive proximity switch; and the solenoid valve 6 is a one-way solenoid valve that only discharges air in the outward direction. The limit base 1 is made of carbon steel or stainless steel, and the float 2 is made of stainless steel. The entire float 2 is capable of floating on the surface of the oil. The float seal 3 is made of nitrile rubber or polytetrafluoroethylene.

[0027] See also Figure 1The oil filtering device provided by the present invention also includes a moisture-proof air intake mechanism that communicates with the interior of the tank body. Exemplarily, the moisture-proof air intake mechanism includes an air inlet 10 and a moisture-proof component 8, and the air inlet 10 communicates with the interior of the tank body through the moisture-proof component. The moisture-proof component 8 includes a box body and moisture-proof sponge or silica gel particles filled in the box body; the air inlet 10 communicates with the interior of the tank body through the interior of the box body. The moisture-proof air intake mechanism also includes a one-way valve 7; the air inlet 10 communicates with the interior of the tank body through the interior of the box body and the one-way valve 7. When the oil filter equipment is draining oil or performing other operations, gas needs to be inhaled into the tank body. Because the internal pressure of the oil filter equipment tank body is lower than the external atmospheric pressure, the gas passes through the component containing silica gel particles inside the moisture-proof component 8 to remove moisture in the air. The dry gas then enters the pipeline through the one-way valve 7 and enters the tank body of the oil filter equipment through the gap between the float 2 and the gas passage pipe. When the pressure inside the tank body of the oil filter equipment is equal to or greater than the external air pressure, the one-way valve 7 is cut off. Only when the pressure inside the tank body of the oil filter equipment is lower than the external air pressure, the one-way valve 7 is opened.

[0028] The oil filter device provided by the present invention detects the presence of gas and oil within the tank. If oil enters the tank, the gas within the tank is discharged. Discharging gas stops when the tank is full of oil, ensuring that the oil does not discharge along with the gas, thus preventing oil leakage and allowing full contact between the oil and the filter element within the tank. This improves the processing efficiency of the oil filter device. The present invention includes a limiter and a proximity switch. When the tank is full of oil, a float drives the limiter upward, causing the proximity switch to activate, which in turn activates the solenoid valve to shut off the exhaust, preventing oil discharge. Furthermore, the device also provides a function for allowing air to enter. During maintenance, when the oil filter tank needs to be drained, air enters the filter tank through a moisture-proof component containing silicone and then enters the tank through a one-way valve. The air enters and exits the oil filter tank at different locations. The solenoid valve is connected to the oil filter device's electrical pump. The solenoid valve opens to discharge air only when the oil filter device is operating, preventing leakage during equipment downtime.
