[0029] Example 1: Please refer to Figure 1-Figure 5 As shown, the utility model provides a technical solution: a filtering and separating device for recovering clean coal tar, comprising a tank body 1, a feeding port for feeding is provided at the top of the tank body 1, and a cover plate 2 is rotatably installed above the feeding port, a discharge port 3 is provided at the side of the tank body 1, a driving motor 4 is fixedly connected to the bottom end of the tank body 1, and a heating device 20 is fixedly connected to the bottom end of the tank body 1;

[0030] The present technical solution sets up the application of the cover plate 2 and the driving motor 4. When in use, the device is first placed on a stable ground, and the cover plate 2 is further rotated to open. Then, the coal tar to be filtered is transported into the tank body 1 from the opening at the upper end of the tank body 1, and the cover plate 2 is further rotated to close, and the driving motor 4 is turned on at the same time, so as to filter the coal tar in the tank body 1 to remove impurities and particulate matter therein. After the filtering is completed, the coal tar is discharged from the side discharge port 3, thereby completing a series of operations.

[0031] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. The existing one will generate noise and vibration during operation, which will not only cause certain harm to the health of the operator, but also long-term vibration may cause damage to the device, requiring regular maintenance and increasing labor costs. This technical solution is as follows: Figure 1 , Figure 2 and Figure 4 , Figure 5As shown, a filter assembly of a filter device is disclosed, wherein the output end of a driving motor 4 is arranged to penetrate deeply into a tank body 1 and is fixedly connected to a rotating shaft 5, and a first bevel gear 6 is nested on the rotating shaft 5, a first filter cartridge 7 is fixedly connected to the top of the rotating shaft 5, and a first magnet 8 is fixedly connected to the side wall of the first filter cartridge 7, a recovery chamber 21 is opened in the tank body 1, and a fixed block 9 is fixedly installed in the recovery chamber 21, a second bevel gear 10 is rotatably installed in the fixed block 9, and a sleeve rod 11 is rotatably installed at the top of the fixed block 9, a third bevel gear 12 cooperating with the second bevel gear 10 is nested on the sleeve rod 11, and the top end of the sleeve rod 11 penetrates and extends out of the fixed block 9 and is fixedly connected to a second filter cartridge 13, a knocking rod 14 is rotatably installed on the side of the second filter cartridge 13, and a second magnet 15 is fixedly connected to the knocking rod 14, the first bevel gear 6 is located in the fixed block 9, and the first bevel gear 6 is meshed with the second bevel gear 10, the first filter cartridge 7 is rotatably arranged in the second filter cartridge 13, and the diameter of the leakage hole on the first filter cartridge 7 is larger than the diameter of the leakage hole on the second filter cartridge 13, and a plurality of first magnets 8 are arranged in a circular array about the center of the first filter cartridge 7, the sleeve rod 11 is sleeved on the outside of the rotating shaft 5, and the sleeve rod 11 is rotatably connected to the rotating shaft 5, and the third bevel gear 12 on the sleeve rod 11 is meshed with the second bevel gear 10, the second filter cartridge 13 is arranged in the baffle 16, and a liquid channel is left between the second filter cartridge 13 and the baffle 16, and the bottom end of the liquid channel is connected to the recovery chamber 21, the knocking rod 14 is a "V"-shaped structure, and there are two knocking rods 14 symmetrically arranged about the second filter cartridge 13, and a torsion spring providing a reset elastic force is connected between the knocking rod 14 and the second filter cartridge 13, the second magnet 15 on the knocking rod 14 is aligned with the first magnet 8, and the second magnet 15 and the first magnet 8 The opposite side is the same magnetic pole.

[0032] In this technical solution, Figure 1 , Figure 2 As shown, by utilizing the arrangement of the first bevel gear 6, the second bevel gear 10 and the third bevel gear 12, the first bevel gear 6 engages with the second bevel gear 10 to rotate when rotating, and the second bevel gear 10 engages with the third bevel gear 12 to reverse, so that the first filter cartridge 7 and the second filter cartridge 13 rotate simultaneously, and the coal tar is filtered multiple times by centrifugal force, thereby improving the overall filtering efficiency and quality. At the same time, by utilizing the arrangement of the first magnet 8 and the second magnet 15, the knocking rod 14 intermittently knocks the first filter cartridge 7 to prevent impurities from clogging the first filter cartridge 7, thereby improving the filtering effect and having strong practicality.

[0033] Its use is as Figure 4 , Figure 5In the technical solution shown, first, the coal tar will enter the first filter cartridge 7, and at this time, the driving motor 4 will work, thereby driving the rotating shaft 5 to rotate, and further the rotating shaft 5 will drive the first filter cartridge 7 to rotate, and the coal tar in the first filter cartridge 7 will be filtered by the centrifugal force generated by the rotation, and at the same time, the rotating shaft 5 will drive the first bevel gear 6 to rotate when rotating, so that the first bevel gear 6 meshes with the second bevel gear 10 to rotate, and further the second bevel gear 10 meshes with the third bevel gear 12 to rotate in the opposite direction, thereby driving the sleeve rod 11 to rotate, so that the sleeve rod 11 drives the second filter cartridge 13 to rotate in the opposite direction, and at this time, the coal tar filtered into the second filter cartridge 13 by the first filter cartridge 7 is filtered twice by the centrifugal force generated by the rotation of the second filter cartridge 13, so that the filtered coal tar enters the channel between the baffle 16 and the second filter cartridge 13, and flows into the recovery chamber 21 through the opening at the bottom of the channel;

[0036] In this technical solution, Figure 2As shown, by using the arrangement of the nozzle 18 and the scraper 19, the water in the filtered oil-water mixture is evaporated after being heated, and the generated high-temperature water vapor is sprayed out by the nozzle 18, thereby driving the rotating member 17 to rotate, so that the rotating member 17 drives the scraper 19 to rotate along the surface of the baffle 16, and the coal tar attached to the baffle 16 is scraped off, thereby avoiding the waste and loss of coal tar, improving the recovery rate of coal tar, and reducing costs.

[0037] Its use is as Figure 1 and Figure 3-Figure 5 In the technical solution shown, first, the heating device 20 heats the oil-water mixture filtered out of the recovery chamber 21 to evaporate the water in the coal tar. At this time, the evaporated water vapor flows into the nozzle 18 through the channel in the baffle 16, and then is ejected through the nozzle 18, pushing the rotating member 17 to rotate, so that the rotating member 17 drives the scraper 19 to rotate, and then the rotating scraper 19 scrapes off the coal tar attached to the inner wall of the baffle 16 to avoid residue.
