[0044] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0045] As Figures 1 to 10 shown, the present solution discloses a special centrifuge for tar residue. The specific usage process is as follows: First, cover the cylinder cover on the outer cylinder, then start the driving motor, use the driving motor to drive the first screen and the second screen to rotate, and then convey the liquid and semi-liquid materials upward from the opening below the feeding pipe until they are conveyed into the second screen. Since the second screen rotates with the driving motor, the conveyed materials will be centrifugally separated. As the materials are continuously conveyed into the second screen, the materials will be conveyed to the first screen along the first gap and the second gap. With the rotation of the first screen and the second screen, the liquid doped in the materials will be precipitated into the first water tank and discharged through the drain pipe. The materials remaining on the first screen will continuously move upward along the inner wall slope of the first screen due to the action of centrifugal force until they are thrown out of the first screen to the outer cylinder outside the first screen. The thrown materials are blocked by the outer cylinder and the cylinder cover, and then the materials fall due to gravity and fall out from the discharge port on the base into the receiving box provided below the base, thus completing the solid-liquid separation function.

[0046] At the same time, in order to improve the filtration efficiency and reduce the materials remaining on the screen, after the feeding is completed using the feeding pipe, connect the feeding port at the lower end of the feeding pipe to the cleaning pipeline, and use the cleaning pipeline to inject cleaning liquid into the centrifuge through the feeding pipe. The cleaning liquid is determined according to the specific materials to be centrifuged. For example, if the liquid doped in the materials to be centrifuged is water or ammonia water, etc., then use the cleaning pipeline to inject the same type of liquid into the centrifuge. The injection of the cleaning liquid can wash the objects remaining in the feeding pipe, the second screen, the first gap, and the second gap into the first screen, improve the centrifugation efficiency, and reduce residual waste.

[0047] The overall structure includes structures such as a base 7 and an outer cylinder 71. Inside, it mainly includes a first screen 1 assembly and a second screen 4 assembly. The first screen 1 assembly includes a first screen 1 and a first water tank 2. The specific model of the first screen 1 can be configured according to the actual requirements of centrifugal filtration. The first water tank 2 is arranged outside the first screen 1. The liquid separated during the rotation of the first screen 1 flows into the first water tank 2. The bottom of the first screen 1 has an opening, and a first mounting flange 11 is provided at the opening. The bottom of the first water tank 2 has a first bottom plate 21, and the first bottom plate 21 is inclined. The lower end of the first bottom plate 21 is connected to a drain pipe 22;

[0048] The second screen 4 assembly is arranged on the first mounting flange 11 and mainly includes a second screen 4. The centrifuge in this solution uses a feeding pipe 5 for feeding. The feeding direction of the material is from bottom to top. The material first flows into the second screen 4 from the opening at the top of the feeding pipe 5. Since there is a feeding port cover 41 above the second screen 4, and at the same time, a first gap 43 and a second gap 44 for facilitating the flow of the material are formed among the second screen 4, the feeding outer retaining ring 42, and the feeding port cover 41. The material is transported to the first screen 1 after passing through the first gap 43 and the second gap 44 in sequence, and finally completes the centrifugal separation work as the first screen 1 rotates;

[0049] The drive assembly for driving the first screen 1 to rotate includes a rotating shaft 32. The top of the rotating shaft 32 is connected to the first mounting flange 11 of the first screen 1 through a rotating fixed flange 31, and the bottom is connected to an external drive motor. Thus, the drive motor drives the first screen 1 to rotate. The inside of the rotating shaft 32 is a hollow structure, and the hollow structure serves as a first cavity for accommodating the feeding pipe 5. The outer wall of the feeding pipe 5 is connected to the first cavity of the rotating shaft 32 through a first rotating shaft 33. During the operation of the drive motor, the rotating shaft 32 rotates relative to the feeding pipe 5, and the feeding pipe 5 remains stationary relative to the ground. At the same time, a fixed pipe 6 is provided in this solution. The fixed pipe 6 is arranged on the outer wall of the rotating shaft 32. On the one hand, the fixed pipe 6 serves as a support structure for the first screen 1 assembly, and on the other hand, it covers the outside of the rotating shaft 32 to play a safety protection role;

[0050] The function of setting the second screen is, on the one hand, to assist the feeding of the feeding pipe, and on the other hand, for the material remaining in the second screen, use the second screen with a smaller size that rotates synchronously with the first screen to perform centrifugal separation on the material remaining in the second screen;

[0051] The driving motor is not shown in the drawings of this solution. The driving motor can be configured according to actual requirements. A motor guard 73 is provided on the base 7 of this solution. A motor mounting plate 74 is provided in the motor guard 73. A corresponding mounting groove 75 structure is provided on the base 7. The position of the motor mounting plate 74 relative to the mounting groove 75 is adjustable. During actual use, the driving motor is placed in the motor guard 73 by using the motor mounting plate 74, and the above adjustable mounting structure is used to adapt to motors of different model sizes.

[0052] Shock absorbers 8 are provided at the four corners of the base 7 of this solution. The size and model of the shock absorbers 8 can be configured according to actual use requirements.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
