[0002] At present, the asphalt oil produced at the bottom of the vacuum tower contains a large amount of substances such as gum, asphaltene, and ash, and is particularly likely to block the discharge pipeline of the equipment. Therefore, factories usually add lubricating oil at the same time as the asphalt oil is produced to improve the passability of the asphalt oil in the pipeline. Although the blockage of the discharge pipeline by the asphalt oil is avoided, the lubricating oil is only used once and the consumption is huge, which in turn leads to a relatively high production cost of the asphalt oil.

The first motor is fixedly installed on the inner top of the n-shaped plate, and the lower end of the first screw rod passes through the top wall of the n-shaped plate and is connected to the output end of the first motor. The lifting plate is located above the n-shaped plate. The guide rods are located on the left and right sides of the n-shaped plate. The second motor is located below the first motor, and both are inside the n-shaped plate.

Then, after the discharge channel stops discharging the mixture, the lifting device will drive the immersion block to descend and partially immerse it in the mixture, so as to raise the liquid level of the mixture. Since the lubricating oil is lighter than the asphalt oil, after the immersion block is partially immersed in the above mixture, the lubricating oil on the top layer will gradually rise and gradually overflow from the top of the cylindrical partition.

By adopting the above-mentioned n-shaped plate 9, not only can it provide support for the first motor 73, but also in cooperation with the cover plates 10, it can protect the working safety of the first motor 73 and the second motor 84.

[0025] Further, the top end of the guide rod 71 is fixedly connected with a second screw rod 711 passing through the lifting plate 72, and the outer diameter of the second screw rod 711 is smaller than the outer diameter of the guide rod 71. A second nut 712 is threadedly connected to the second screw rod 711, and the second nut 712 and the top end of the guide rod 71 are respectively located on the upper and lower sides of the lifting plate 72.

[0027] Furthermore, the immersion block 6 is in the shape of a frustum of a cone with the narrow end facing downwards. By adopting the immersion block 6 of the above shape, when the immersion block 6 is immersed, the rising speed of the liquid level can be slowly increased, thereby avoiding the too fast initial speed of the liquid level rise and affecting the stratification of the asphalt oil and the lubricating oil.

[0028] Furthermore, an ultrasonic liquid level sensor 124 is fixedly arranged on the tank cover 12, and the sensing end of the sensor penetrates into the tank body 11 to detect the liquid level height inside the cylindrical partition plate 2. By adopting the above ultrasonic liquid level sensor 124, the staff can quickly know the liquid level height of the mixed liquid in the tank, so as to control the lifting assembly 7 to drive the immersion block 6 to descend to an appropriate height for immersing and squeezing out the lubricating oil.

[0029] Working principle of this embodiment:

[0030] When the discharge channel of the vacuum tower discharges the mixed liquid of asphalt oil and lubricating oil, it will first pass through the feed pipe 4, enter the inside of the tank body 11, and gather in the middle of the cylindrical partition plate 2. Then, the motor two 84 drives the rotating shaft 81 to rotate, so that the stirring rod 83 and the scraper 82 connected to the side wall of the rotating shaft 81 continuously rotate and stir the asphalt oil, thereby reducing the phenomena such as coking and solidification of the asphalt oil in the receiving tank 1; then, after the discharge channel stops discharging the mixed liquid, the lifting device will drive the immersion block 6 to descend and partially immerse it in the mixed liquid, so as to raise the liquid level of the mixed liquid. Since the lubricating oil is lighter than the asphalt oil, after the immersion block 6 is partially immersed in the above mixed liquid, the uppermost lubricating oil will gradually rise and gradually overflow from the top of the cylindrical partition plate 2; finally, the overflowing lubricating oil will pass through the filter holes 123 of the conical ring plate 122, gather and be recycled in the gap between the outer wall of the cylindrical partition plate 2 and the inner wall of the tank body 11, and under the output of the oil outlet pipe 3 and the output pump 31, it will circulate back to the inlet of the discharge channel of the vacuum tower again to lubricate the subsequent produced asphalt oil, thereby reducing the loss of the lubricating oil and lowering the production cost of the asphalt oil in this way.
