Description

Technical Field

[0001] The utility model belongs to the technical field of lubricating oil stations supporting rotating equipment, and in particular relates to an oil fume exhaust pipeline inside a lubricating oil station. Background Art

[0002] The lubricating oil station is mainly used to lubricate and cool the shaft system of rotating equipment by establishing the circulation of lubricating oil. During this period, the lubricating oil is heated to produce oil smoke, which forms a positive pressure in the closed oil tank, which can easily cause poor oil circulation or even oil leakage. In order to ensure the discharge of oil smoke inside the lubricating oil station, the oil station is designed with a smoke exhaust fan, which, under the action of the induced draft fan, discharges the high-temperature smoke inside the oil tank to the outside.

[0003] When the exhaust fan fails or has a mechanical failure, the exhaust will be blocked. At this time, the internal pressure of the oil tank increases, and then the oil leakage at the bearing seal occurs. The gland on the top of the oil tank needs to be manually removed, but a large amount of unfiltered oil smoke is discharged into the factory, causing environmental pollution. Therefore, a kind of internal oil smoke exhaust pipeline of the lubricating oil station is proposed. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Embodiment 1, as Figure 1-2As shown, an internal oil fume exhaust pipeline of a lubricating oil station includes an oil station 1, and the oil station 1 is used to store lubricating oil. A refueling port 2 is provided on the top of the oil station 1, and lubricating oil is added to the oil station 1 through the refueling port 2. A lubricating pipeline 3 is provided on one side of the oil station 1, and the lubricating pipeline 3 connects the oil station 1 and the equipment that needs lubrication, and is used to transport the lubricating oil. The lubricating pipeline 3 is provided with a lubricating oil pump 4, a cooler 5, a filter 6 and a lubrication point 7. The lubricating oil pump 4 is used to transport the lubricating oil from the oil station 1 to the equipment that needs lubrication. The cooler 5 can reduce the temperature of the lubricating oil to prevent the lubricating oil from overheating. The filter 6 is used to filter impurities in the lubricating oil to ensure the cleanliness of the lubricating oil. The lubrication point 7 is a part of the external equipment that needs lubrication, and the oil is transported outward for lubrication.

[0020] A discharge pipe 8 is provided on the top of the oil station 1, and the discharge pipe 8 is used to discharge the oil smoke generated inside the oil station 1. A fume fan 9 is provided on the discharge pipe 8, and the fume fan 9 plays a role of extraction, and is used to lead the oil smoke in the oil station 1 to the outside. A one-way valve 12 is provided on the discharge pipe 8, and the one-way valve 12 is used to control the flow direction of the oil smoke in the discharge pipe 8 to prevent backflow.

[0021] The top of the exhaust pipe 8 is connected to the exhaust pipe 13, which is used to receive the oil smoke and collect and discharge the oil smoke. A pneumatic stop valve 14 is provided at the rear end of the exhaust pipe 13, which is used to control the opening and closing of the exhaust pipe 13, and can control whether to introduce gas from the rear end of the exhaust pipe 13.

[0022] The following is a detailed description of the design of the above key components:

[0023] Auxiliary pipes 10 are arranged in parallel at both ends of the discharge pipe 8, and an auxiliary fan 11 is arranged on the auxiliary pipe 10. A one-way valve 12 is arranged on the auxiliary pipe 10. The setting of the auxiliary pipe 10 can play a supplementary role to the discharge pipe 8. The auxiliary fan 11 can assist the exhaust of oil smoke in the auxiliary pipe 10, and the flow direction of the oil smoke can be controlled by the one-way valve 12 to prevent backflow. The auxiliary fan 11 is interlocked with the pneumatic stop valve 14, and the opening and closing of the pneumatic stop valve 14 are interlocked by the operation of the auxiliary fan 11.

[0024] The pneumatic stop valve 14 is a two-position three-way solenoid valve, which can be opened and closed by electromagnetic control. The pneumatic stop valve 14 is interlocked with the oil fume blower 9, and the opening and closing of the pneumatic stop valve 14 is controlled by the operation of the oil fume blower 9.

[0025] The rear side of the smoke exhaust pipe 13 is connected to an external low-pressure air source, which can provide additional air source support to accelerate the exhaust speed of the oil smoke in the exhaust pipe 8.

[0026] The connection between the exhaust pipe 8 and the smoke exhaust pipe 13 is designed as a venturi tube type, which can increase the sealing and stability between the pipes, prevent oil fume leakage, ensure the normal operation of the exhaust mechanism, facilitate the smooth flow of oil fume exhaust, reduce resistance, and improve exhaust efficiency.

[0027] Embodiment 2, as shown in Embodiment 1, is an internal oil fume exhaust pipeline of a lubricating oil station, which is equipped with an oil fume fan 9 and an auxiliary fan 11 for mutual backup. The power supply of the two fans comes from different power supply lines, and the mutual backup interlocking protection of operation signal loss is designed.

[0028] In normal operation, the oil fume fan 9 is running. Under the action of airflow, the one-way valve 12 on the auxiliary pipe 10 is closed, and the auxiliary fan 11 is in a static standby state. When the oil fume fan 9 is abnormal such as power failure, and the operation signal is lost, the auxiliary fan 11 is interlocked and automatically starts to run. At the same time, the one-way valve 12 at the fan outlet automatically changes state under the action of airflow. And an alarm prompt is issued on the DCS system.

[0029] The pneumatic stop valve 14 is interlocked with the fan operation signal. During the normal operation of the oil fume fan 9 or the auxiliary fan 11, the pneumatic stop valve 14 is closed and the solenoid valve is energized. When the oil fume fan 9 and the auxiliary fan 11 lose power at the same time, the solenoid valve interlock on the instrument air pipe of the pneumatic stop valve 14 automatically loses power, and the pneumatic stop valve 14 opens. Low-pressure air with a pressure of 0.6MPa automatically flows into the exhaust pipe 13.

[0030] The connection between the discharge pipe 8 and the smoke exhaust pipe 13 is designed as a venturi tube. After the low-pressure air flows in, it forms an ejection to take away the oil smoke, thereby preventing the oil smoke from accumulating inside the oil tank to form a positive pressure.

[0031] The standard parts used in the utility model can all be purchased from the market, special-shaped parts can be customized according to the description in the specification and the drawings, the specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art, the machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
