[0037] Embodiment 1

[0038] like Figure 1-5 As shown, the utility model provides a tar residue multi-stage centrifugal separation and recovery device: comprising a centrifuge 2 for separating tar residue; and a feeding assembly arranged on one side of the centrifuge 2.

[0039] The feeding assembly includes a transport channel 3, in which a transport cavity 301 is provided. The transport channel 3 is inclined, and a feed port 302 is provided at the lowest end of the transport channel 3. The feed port 302 is communicated with the transport cavity 301, and a funnel is provided at the top of the feed port 302. By providing the funnel, the feeding range of the feed port 302 can be expanded, thereby facilitating the staff to dump tar residue into the transport cavity 301. A transport motor 4 is provided on the transport channel 3, and the output shaft of the transport motor 4 is fixedly connected with a conveying shaft 401, which is provided in the transport cavity 301. An auger 402 adapted to the transport cavity 301 is provided on the conveying shaft 401, and a heating rod 403 is provided in the conveying shaft 401. A transport motor 4 is arranged on the transport channel 3, and the output shaft of the transport motor 4 is connected to a conveying shaft 401, and an auger 402 is arranged on the conveying shaft 401. The transport motor 4 can be started to drive the auger 402 to rotate, and the auger 402 can drive the tar residue to move forward smoothly in the transport chamber 301, and can also mix and stir the tar residue during transportation. A through groove connected to the highest end of the transport channel 3 is opened in the conveying shaft 401, and a heating rod 403 is inserted in the through groove. By opening the through groove and inserting the heating rod 403 in the through groove, the temperature in the transport chamber 301 is made higher. The higher temperature can make some heavy components in the tar residue be pyrolyzed or lightened to a certain extent, thereby reducing its viscosity. The reduction in viscosity helps to improve the fluidity of the tar residue during the centrifugal separation process, making it easier to separate. It can also increase the density difference between different components in the tar residue. The greater the density difference, the better the separation effect during centrifugal separation. It can also reduce the size of solid particles in the tar residue, which is conducive to increasing its sedimentation rate during the centrifugal separation process. A limiting block 404 is integrally formed at the end of the heating rod 403. A power cord is connected to the limiting block 404. By setting the limiting block 404, the heating rod 403 is not in direct contact with the conveying shaft 401, and the through groove in the conveying shaft 401 is sealed to prevent the heat from dissipating when the heating rod 403 is heated, so that the heating effect of the heating rod is better and the conveying A sealed bearing 405 is provided at the connection between the shaft 401 and the transport channel 3. The sealed bearing 405 is provided to improve the sealing performance of the connection, and the tar residue will not enter the through groove opened in the conveying shaft 401, and the heating rod 403 will not damage it. A discharge port 303 is provided at the highest end of the transport channel 3. The discharge port 303 is located above the centrifuge 2, and the discharge port 303 is connected to the transport chamber 301. By tilting the transport channel 3 and making the discharge port 303 above the centrifuge 2, the tar residue can be transported to the top of the centrifuge 2 by itself when passing through the transport chamber 301, and then discharged through the discharge port 303 and falls into the centrifuge 2, thereby facilitating the loading of the centrifuge 2.

[0040] Furthermore, a first threaded hole 202 is provided on the bottom surface of the separation chamber 201, and a first threaded block 7 is threadedly connected in the first threaded hole 202. A centrifugal frame 5 is arranged in the separation chamber 201, and a through hole 502 adapted to the first threaded block 7 is provided on the bottom surface of the centrifugal frame 5. One end of the first threaded block 7 is inserted into the through hole 502, so that the bottom surface of the centrifugal frame 5 is connected to the first threaded hole 202, so that the bottom surface of the centrifugal frame 5 can be opened by unscrewing the first threaded block 7, so as to discharge the solid separation separately.

[0041] Furthermore, a second threaded hole 203 is provided on the bottom surface of the separation chamber 201, and a second threaded block 701 is threadedly connected in the second threaded hole 203, so that after solid-liquid separation, the second threaded hole 203 can be opened by unscrewing the second threaded block 701 to discharge the liquid separation. A chamfer 204 is provided on the bottom surface of the separation chamber 201, and the chamfer 204 allows the second threaded hole 203 to be located at the lowest point of the entire bottom surface of the separation chamber 201, so that the liquid separation will be discharged from the separation chamber 201 through the second threaded hole 203 under the influence of gravity.

[0042] Furthermore, a top cover 6 is provided on the top surface of the centrifuge 2, and a separation motor 601 is provided on the top surface of the top cover 6, so that the top cover 6 can be removed from the centrifuge 2, which makes the unloading of the transport channel 3 more convenient and also facilitates the cleaning of the internal space of the separation chamber 201. The output shaft of the separation motor 601 is connected with a connecting block 602, and a positioning block 501 adapted to the connecting block 602 is provided on the top of the centrifugal frame 5. By setting the positioning block 501 and the connecting block 602, the separation motor 601 can drive the centrifugal frame 5 to rotate after installation, so as to centrifugally separate the tar residue in the centrifugal frame 5.

[0043] Furthermore, a separation chamber 201 is provided in the centrifuge 2, a limiting groove 205 is provided in the separation chamber 201, a ball 206 is provided in the limiting groove 205, and the ball 206 contacts the bottom surface of the centrifugal frame 5. By arranging the ball 206 in the chamfer 204, the sliding friction of the centrifugal frame 5 is converted into rolling friction during rotation, and the friction resistance is reduced by reducing the contact area, thereby allowing the centrifugal frame 5 to rotate more smoothly.

[0044] Embodiment 2

[0045] Based on the first embodiment, specifically, Figure 1-3As shown, it also includes a moving component, which includes a moving base 1. Universal wheels 101 are arranged at the triangular part of the bottom surface of the moving base 1. Support columns 102 are arranged on the top surface of the moving base 1. There are multiple support columns 102, which are respectively fixedly connected to the transport channel 3 and the centrifuge 2, so that the centrifuge 2 and the transport channel 3 can be transported by the universal wheels 101, so that the positions of the centrifuge 2 and the transport channel 3 are no longer fixed, and can be moved according to the position of the tar residue that needs to be processed, making the use of the device more convenient.

[0046] Working principle:

[0047] To prevent blockage during feeding.

[0048] In the utility model, a feeding component is provided.

[0049] The staff can pour the tar residue from a low place into the transport channel 3, and then start the transport motor 4 to drive the auger 402 to rotate to transport the tar residue to the top of the centrifuge 2 and then send it out. The transportation through the auger 402 can reduce the possibility of tar residue being blocked in the transport channel 3, and the tar residue can be mixed and stirred during the transportation process, and the heating rod 403 can be started at the same time to heat the tar residue in transportation, so that the temperature of the tar residue is increased, thereby reducing the viscosity of the tar residue, which can further reduce the possibility of tar residue being blocked in the transport channel 3 and make the tar residue easier to separate.
