Description

Technical Field

[0001] The utility model relates to the technical field of lubrication system accessories, in particular to an automatically controlled three-stage filtering smoke exhaust fan for a lubrication system. Background Art

[0002] At present, when the oil station of the lubricating oil system is running, oil smoke and water mist will be generated. Generally, the oil tank will be connected to the outside, and oil smoke and water mist will still be generated and accumulated in the oil tank, deteriorating the oil quality. If not handled in time, it will lead to: 1. The oil mist is sucked into the rotating parts of the main engine, causing the oil mist to "run and emit", leading to safety accidents such as fire. 2. The oil mist escapes from the ventilation points of the oil tank, causing environmental pollution, and will also cause mutual influence between equipment, making the equipment unable to be used indoors. The current common solution is to install an exhaust fan on the top of the oil tank to lead the oil mist to be discharged outside the factory, causing a large number of oil particles to be entrained and discharged together with the oil mist, accelerating the consumption of lubricating oil in the lubrication system.

[0003] For example, the suction type oil mist separator with a coalescing filter element with the publication number CN215462722U relates to the technical field of oil mist separation. It includes an oil tank, a fan, and a filter cartridge. The upper part of the filter cartridge is a separation chamber, and the lower part is an oil mist input chamber. The oil tank is located below the filter cartridge. An oil mist inlet is provided on the side wall of the oil mist input chamber. The oil mist inlet is connected to the upper end of the oil tank through a pipeline. An oil return pipe is connected between the bottom end of the oil mist input chamber and the oil tank. The separation chamber is provided with a coalescing filter element, the inlet end of which is connected to the lower oil mist input chamber. The filter cartridge wall above the coalescing filter element is provided with an air suction port connected to the fan. The utility model can recover the condensed lubricating oil into the oil tank of the oil lubrication system through the coalescing filter element, thereby reducing the loss of lubricating oil and eliminating the external exhaust pipe of the conventional exhaust fan, saving operation and maintenance costs.

[0004] In practical applications, the above technical solution has a small number of filtration times for oil smoke, a poor filtering effect, and a poor treatment effect for oil smoke.

[0005] Therefore, it is necessary to invent an automatic controlled three-stage filtering smoke exhaust fan for a lubrication system to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4 An automatic controlled three-stage filtering smoke exhaust fan for a lubrication system shown in the figure comprises an air inlet oil pipe 1, two centrifugal fans 2 are fixedly arranged at one end of the air inlet oil pipe 1, a primary filter pipe 3 is fixedly arranged between the input end of the centrifugal fan 2 and the air inlet oil pipe 1, a secondary filter pipe 4 is fixedly arranged at the output end of the centrifugal fan 2, a three-way pipe 5 is fixedly arranged between the two secondary filter pipes 4, an air outlet oil pipe 6 is fixedly arranged at the top end of the three-way pipe 5, and a three-stage filter pipe 7 is fixedly arranged between the air outlet oil pipe 6 and the three-way pipe 5;

[0023] Specifically, a sedimentator 8 is provided below the air inlet oil pipe 1, and a plurality of sedimentation oil return pipes 9 are provided through the outer wall of the sedimentator 8, and the plurality of sedimentation oil return pipes 9 are respectively fixedly provided at the bottom ends of the primary filter pipe 3, the secondary filter pipe 4 and the tertiary filter pipe 7, and a hexagonal ball valve 10 is provided through the outer bottom end of the sedimentator 8, and the waste oil in the sedimentator 8 can be discharged through the hexagonal ball valve 10;

[0024] More specifically, the first-stage filter tube 3, the second-stage filter tube 4 and the third-stage filter tube 7 are all fixedly provided with an oil mist filter element 11. The input end of the oil mist filter element 11 in the first-stage filter tube 3 fits with the oil inlet pipe 1, the output end of the oil mist filter element 11 in the second-stage filter tube 4 fits with one end of the three-way pipe 5, and the output end of the oil mist filter element 11 in the third-stage filter tube 7 fits with one end of the oil outlet pipe 6. The oil smoke passes through the three oil smoke filter elements 11 in different filtering modes, which can ensure the filtering effect of the oil smoke.

[0025] In addition, a pressure gauge 12 is fixedly arranged in the middle of the air inlet oil pipe 1, and a butterfly valve 13 is fixedly arranged between the air inlet oil pipe 1 and the primary filter pipe 3. The air pressure inside the system can be observed through the pressure gauge 12, and the amount of oil smoke entering can be controlled through the butterfly valve 13 to ensure stable operation inside the device;

[0026] Moreover, one end of the primary filter tube 3, the secondary filter tube 4 and the tertiary filter tube 7 are all fixedly provided with a check valve, and the setting of the check valve ensures the flow stability of the oil smoke inside the device.

[0027] Working principle of this utility model:

[0028] When the device is in use, the two centrifugal fans 2 work to generate negative pressure, and the oil smoke is sucked down by the negative pressure through the air inlet oil pipe 1. The oil smoke enters the primary filter pipe 3 through the air inlet oil pipe 1, and then enters the secondary filter pipe 4 under the guidance of the centrifugal fan 2, and enters the tertiary filter pipe 7 after being filtered in the secondary filter pipe 4, and is discharged from the device through the air outlet oil pipe 6 after being filtered in the tertiary filter pipe 7. In this process, the primary filter pipe 3, the secondary filter pipe 4 and the tertiary filter pipe 7 can filter the oil smoke three times, and the filtered waste oil enters the sedimentator 8 through the sedimentation return oil pipe 9 to realize the recovery of the waste oil.

[0029] Since the input end of the oil mist filter 11 in the primary filter tube 3 is in contact with the air inlet oil pipe 1, the oil smoke directly enters the oil mist filter 11 and passes through the inner wall of the oil mist filter 11 to be discharged. At this time, the oil smoke passes through the oil mist filter 11 from the inside to the outside to complete the filtration. Since the output end of the oil mist filter 11 in the secondary filter tube 4 is in contact with one end of the three-way pipe 5, the oil smoke passes through the outer wall of the oil mist filter 11 into the interior, and then enters the third filter through one end of the oil mist filter 11. Tube 7, at this time, the oil smoke passes through the oil mist filter element 11 from the outside to the inside to complete the filtration. Since the output end of the oil mist filter element 11 located in the three-stage filter tube 7 is in contact with one end of the air outlet oil pipe 6, the oil smoke passes through the outer wall of the oil mist filter element 11 to enter the inside, and then passes through one end of the oil mist filter element 11 to enter the air outlet oil pipe 6. At this time, the oil smoke passes through the oil mist filter element 11 from the outside to the inside to complete the filtration. The oil smoke passes through the three oil smoke filters 11 in different filtering methods, which can ensure the filtration effect of the oil smoke.

[0030] During the process of treating the oil fume, the air pressure inside the system can be observed through the pressure gauge 12, and the amount of oil fume entering can be controlled through the butterfly valve 13 to ensure stable operation inside the device.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
