Description

Technical Field

[0001] This utility model relates to the field of oil mist filtration and purification technology, specifically a corrosion-resistant vacuum solid-liquid separation oil mist filtration and purification device. Background Technology

[0002] In industrial production, some lubricating oils and cooling oils can form oil mist that is suspended in the air due to high temperature and friction during the operation of machinery. This oil mist not only increases the difficulty of cleaning for workers, but also causes air quality to deteriorate.

[0003] Currently, the main method for treating industrial oil mist and fumes is filtration. In order to alleviate the pressure on single-stage filtration structures, current filtration equipment often adopts multi-stage filtration. The mesh size of multi-stage filtration equipment increases progressively to intercept droplets of different sizes. However, this design has the following problems: although multi-stage filtration can increase the efficiency of oil mist treatment, the oil mist is very sticky and easily adheres to the filter screen, making it difficult to clean and increasing the filtration pressure of subsequent stages. In view of this, this case was developed through in-depth research to address the above problems. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides an implementation scheme: In the current vacuum oil mist filtration equipment, after long-term use, solid particles are not completely filtered out due to the coarse filtration. Therefore, solid particles and oil are easily adhered to the nozzle of the atomizing equipment, which not only affects the gas output efficiency, but also causes solid deposits to easily accumulate at the valve and pipe head due to the affected gas output, resulting in pipeline corrosion.

[0020] To address the aforementioned issues, this application discloses a corrosion-resistant vacuum solid-liquid separation oil mist filtration and purification device, comprising a support frame 1, which serves as the main external frame of the device. An oil inlet pipe 3 is installed on the support frame 1, through which the mixed oil to be filtered is introduced into one side of the device. A coarse filter 4 is connected to one side of the oil inlet pipe 3. First, the solid impurities in the mixture are filtered out by the coarse filter 4. Then, a vacuum tank 5 is connected to one side of the coarse filter 4, through which the mixture after coarse filtration is heated to 60℃-75℃ under vacuum, causing the water vapor in the mixture to evaporate. The water vapor is guided out from the negative pressure side, completing the water separation. Then, a fine filter 6 is connected to one side of the vacuum tank 5, and an oil outlet pipe 7 is connected to one side of the fine filter 6. The recovered oil after fine filtration is discharged from the oil outlet pipe 7.

[0021] A heater 8 is installed inside the vacuum tank 5. The pipeline of the coarse filter 4 passes through the heater 8. After the mixture filtered by the coarse filter 4 enters the heater 8, the heater 8 heats it up to about 75°C. An oil mist spraying pipeline 9 extends from the heater 8. As the oil mist is heated, an atomizer 10 is installed on the oil mist spraying pipeline 9. Under negative pressure, the oil mist is sprayed out from one side of the atomizer 10. Due to the combined effect of vacuum negative pressure and heating, the water vapor in the oil mist quickly forms steam. The water vapor is guided away by the negative pressure and condensed. Then, the cleaning control component 11 installed on the atomizer 10 cleans the atomizer 10 to prevent the residue of the coarse filter from clogging the atomization holes.

[0022] Furthermore, according to the instruction manual appendix Figure 1-3It is known that the cleaning control component 11 includes a cleaning motor 111. The cleaning motor 111 is installed on the top surface of the vacuum tank 5. A cleaning groove is opened on the top surface of the vacuum tank 5. A cleaning rod 113 is installed in the cleaning groove. A sealed bearing 114 is provided on the cleaning groove to seal the cleaning groove and the cleaning rod 113. The top end of the cleaning rod 113 is connected to the cleaning motor 111 through a gear set 112. A cleaning plate 115 is provided at the bottom end of the cleaning rod 113 and is installed on the atomizer 10.

[0023] In the specific implementation process, the cleaning motor 111 drives the cleaning rod 113 to rotate through the gear set 112, thereby causing the cleaning rod 113 to move the cleaning plate 115. Small bristles are set on both sides of the cleaning plate 115 to correspond to the holes of the atomizer 10. During the rotation of the cleaning plate 115, the small holes of the atomizer 10 are cleaned to prevent the atomizer 10 from becoming clogged. The cleaning groove is used to install the cleaning rod 113 and plays a limiting role for the cleaning rod 113. At the same time, the sealed bearing 114 is used to seal the cleaning rod 113 and the cleaning groove to ensure the smooth operation of the vacuum negative pressure.

[0024] As a preferred option, a negative pressure condensing unit 2 is further provided on the support frame, and a steam guide hood is provided on the top of the vacuum tank 5. The steam guide hood is connected to the negative pressure condensing unit 2. The negative pressure condensing unit 2 generates a vacuum negative pressure suction force through a negative pressure pump. Furthermore, a condensing tank is also provided between the negative pressure pump and the vacuum tank 5. The suction force generated by the negative pressure pump is used to connect the condensing pipe to the inside of the vacuum tank 5 through the steam guide hood, so as to guide the steam to the vacuum tank 5.

[0025] As a preferred option, the sealed bearing is a cylindrical plate, and the sealed bearing is fixed to the cleaning tank with screws.

[0026] As a preferred option, the atomizer 10 is a disc-shaped plate with several nozzles around its perimeter. The oil heated on one side of the heater 8 is sprayed out from the atomizer 10 under pressure, and the nozzles on the atomizer 10 perform the atomization function.

[0027] As a preferred option, the end of the cleaning rod 113 extends through the top of the atomizer 10.

[0028] As a preferred option, the cleaning plate 115 is a rectangular plate with brush bristles and several spray holes integrated at both ends.

[0029] In summary, this corrosion-resistant vacuum solid-liquid separation oil mist filtration and purification device reduces solid residue through a three-stage purification system of coarse filtration, vacuum dehydration, and fine filtration. The cleaning control component 11 integrates rotating brushes with negative pressure linkage to achieve dynamic cleaning of the atomizer 10 nozzles, reducing clogging rates and preventing corrosion of pipes by blockages. The vacuum heating module precisely controls the temperature to 75℃, which, combined with the condenser tank, rapidly separates water vapor. The modular negative pressure unit extends maintenance cycles and reduces energy consumption. The fully enclosed structure eliminates secondary pollution, making it suitable for high-precision industrial applications.
