Description

Technical Field

[0001] The utility model relates to the technical field of pyrolysis oil separation, in particular to a pyrolysis oil separation device. Background Art

[0002] Pyrolysis oil is a product obtained by pyrolyzing waste tires. During the pyrolysis process, the waste materials need to be crushed and placed in a sealed container, and then the non-metallic materials are pyrolyzed under a certain temperature and pressure environment to produce pyrolysis oil, and the metal materials are stripped. During the pyrolysis treatment of waste tires, powdery carbon black products are also generated.

[0003] After the pyrolysis oil is generated, the oil liquid needs to be separated from other solid materials for subsequent classification and recycling. The existing pyrolysis oil separation devices generally use the method of natural precipitation to layer the pyrolysis oil and solid materials, and then discharge the pyrolysis oil through the oil outlet pipe set by the device. However, the height of the oil outlet pipe set by the device is fixed. When the depth of the solid materials after precipitation exceeds the position of the oil outlet pipe, the solid materials and the pyrolysis oil will be discharged from the separation device together, affecting the solid-liquid separation efficiency, which is very inconvenient. Summary of the Utility Model

[0004] Based on the above description, the utility model provides a pyrolysis oil separation device to solve the problem that the height of the oil outlet pipe of the existing separation device is fixed, and when the depth of the solid materials after precipitation exceeds the position of the oil outlet pipe, the solid materials and the pyrolysis oil will be discharged from the separation device together.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: A pyrolysis oil separation device includes a separation tank and a sealing cover installed at one end of the separation tank. A threaded member that moves vertically by rotating through threads is installed inside the sealing cover. One end of the threaded member is installed in a conical shape and fits a filtering structure on the inner wall of the separation tank. The inner side of the filtering structure faces the threaded member. The threaded member is in a cylindrical shape, and a liquid inlet for aggregating the oil liquid in cooperation with the filtering structure is provided at one end. A corrugated pipe for extracting the oil liquid is installed inside the threaded member.

[0006] On the basis of the above technical solution, the utility model can be further improved as follows.

[0007] Further, one end of the separation tank is in a conical shape and is provided with a discharge port. A feed port is provided on the outer side of the separation tank. A through hole is opened in the center of the surface of the sealing cover, and an internal thread ring is installed in the through hole.

[0008] Further, the threaded member is composed of a threaded cylinder and a grip rod. The threaded cylinder is installed inside the internal thread ring. The grip rod is installed at one end of the threaded cylinder away from the separation tank and is evenly distributed in a circular shape with the center of the threaded cylinder as the center point. The liquid inlet is evenly distributed in a circular shape at the other end of the threaded cylinder.

[0009] Further, the filtering structure is composed of a pressing plate and a filter screen. The pressing plate is conical. The pressing plate is installed at one end of the threaded cylinder away from the grip rod. The conical end of the pressing plate faces the discharge port and is parallel to the conical end of the inner wall of the separation tank.

[0010] Further, the outer side of the pressing plate fits with the inner side of the separation tank. The filter screen is arranged on the surface of the pressing plate in an evenly distributed circular shape. One end of the filter screen close to each other extends into the threaded cylinder at one end away from the grip rod.

[0011] Further, a positioning layer is installed at one end of the inner wall of the threaded cylinder away from the pressing plate. The bellows is installed inside the positioning layer. One end of the bellows extends to the outside of the threaded cylinder, and the other end extends into the conical end inside the pressing plate.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0013] In the present utility model, through the threaded cylinder that is vertically adjusted by screw rotation inside the sealing cover and the bellows installed inside the threaded cylinder, in cooperation with the pressing plate and the filter screen installed at one end of the threaded cylinder, the bellows extends into the separation tank from top to bottom. The depth of the bellows extending into the separation tank is controlled by the vertical movement of the threaded cylinder. During the vertical movement of the threaded cylinder, the pressing plate and the filter screen located at one end of the threaded cylinder can isolate between the bellows and the solid material, separating the oil liquid and the solid material, so that the bellows can only extract the oil liquid, ensuring the efficiency of solid-liquid separation and preventing the solid material and the cracked oil from being discharged from the separation device together.

[0022] Please refer to Figures 1-4 , a pyrolysis oil separation device of the present utility model, comprising a separation tank 1 and a sealing cover 2 installed at one end of the separation tank 1. Inside the sealing cover 2, there is a threaded member that moves vertically by rotating in a threaded manner. One end of the threaded member is installed in a conical shape and fits a filtering structure on the inner wall of the separation tank 1. The inner side of the filtering structure faces the threaded member. The threaded member is in a cylindrical shape, and one end is provided with a liquid inlet 42 that cooperates with the filtering structure to gather the oil liquid. Inside the threaded member, there is a bellows 7 for extracting the oil liquid.

[0023] Please refer to Figure 2 , one end of the separation tank 1 is in a conical shape and is provided with a discharge outlet 12. The discharge outlet 12 is controlled by a valve to open and close. The conical end facilitates the collection and discharge of solid waste from the discharge outlet 12 out of the separation tank 1. A feed inlet 11 is provided on the outer side of the separation tank 1. A through hole 21 is opened in the center of the surface of the sealing cover 2, and an internal thread ring 3 is installed in the through hole 21.

[0024] Please refer to Figure 2, the threaded part is composed of a threaded cylinder 4 and a grip rod 41. The threaded cylinder 4 is installed inside the internal threaded ring 3, and the grip rod 41 is installed at one end of the threaded cylinder 4 away from the separation tank 1 on the outside, and is evenly distributed at equal distances in a ring shape with the center of the threaded cylinder 4 as the center point. The liquid inlet 42 is evenly distributed in a ring shape and opened at the other end of the threaded cylinder 4. The threaded cylinder 4 is cylindrical and hollow inside. The threaded cylinder 4 can move vertically through the positive and reverse threaded rotations inside the internal threaded ring 3 to adjust the depth of the bellows 7 inserted into the separation tank 1 for oil extraction. The setting of the liquid inlet 42 facilitates the oil to enter the inner side of one end of the threaded cylinder 4 connected to the pressing plate 5 for the bellows 7 to extract.

[0025] Please refer to Figure 2 , the filtering structure is composed of a pressing plate 5 and a filter screen 51. The pressing plate 5 is conical. The pressing plate 5 is installed at one end of the threaded cylinder 4 away from the grip rod 41. The conical end of the pressing plate 5 faces the discharge port 12 and is parallel to the conical end of the inner wall of the separation tank 1. The outer side of the pressing plate 5 fits with the inner side of the separation tank 1. The filter screen 51 is arranged at equal distances in a ring shape on the surface of the pressing plate 5. One end of the filter screen 51 close to each other extends into the end of the threaded cylinder 4 away from the grip rod 41. When the threaded cylinder 4 moves vertically to control the depth of the bellows 7 extending into the separation tank 1, the pressing plate 5 and the filter screen 51 at one end of the threaded cylinder 4 can move accordingly and are isolated between the bellows 7 and the solid material to separate the oil and the solid material, so that the bellows 7 can only extract the oil. The conical setting of the pressing plate 5 can be used to adapt to the shape of the conical end of the separation tank 1. When the solid material is less and precipitates inside the conical end of the separation tank 1, the pressing plate 5 can fit with the conical end of the separation tank 1 and insert into the conical end of the separation tank 1 to fit the solid material for separation treatment, ensuring the solid-liquid separation efficiency and facilitating the bellows 7 to extract the oil.

[0026] Please refer to Figure 4 , a positioning layer 6 is installed at one end of the inner wall of the threaded cylinder 4 away from the pressing plate 5. The bellows 7 is installed inside the positioning layer 6. One end of the bellows 7 extends to the outside of the threaded cylinder 4, and the other end extends into the conical end inside the pressing plate 5. The positioning layer 6 is a kind of sponge layer. The positioning layer 6 can be compressed and expanded and restored. The bellows 7 is inserted into the inside of the positioning layer 6, so that the positioning layer 6 generates an expanding force after being compressed to position the bellows 7.
