Description

Technical Field

[0001] This utility model relates to the field of coal tar residue treatment technology, specifically a coal tar separation device. Background Technology

[0002] Coal tar is a black or dark brown viscous liquid with a pungent odor produced during the dry distillation of coal. It is also known as coal paste or coal tar oil. It contains a variety of organic compounds and needs to be separated and purified before use. Generally, separation is carried out by centrifuge.

[0003] However, when the centrifuge tube rotates, impurities adhere tightly to the inner wall due to centrifugal force and remain relatively stationary with respect to the centrifuge tube. On the one hand, long-term accumulation of impurities will reduce the effective separation space, change the flow field inside the tube, and reduce the separation accuracy. On the other hand, the tightly attached impurities will block the filter holes of the centrifuge tube, resulting in a significant decrease in filtration efficiency. In some cases, some coal tar may not be able to pass through the filter holes and be separated. Therefore, it is necessary to redesign a coal tar separation device to address the above problems.

[0024] This utility model provides a technical solution for a coal tar separation device:

[0025] Please see Figures 1-5A coal tar separation device includes a tank body 1, an assembly base 11 fixedly installed inside the tank body 1, a centrifuge cylinder 8 rotatably connected to the bottom wall of the tank body 1, and the centrifuge cylinder 8 rotatably connected to the assembly base 11. The centrifuge cylinder 8 is driven to rotate by a drive mechanism inside the assembly base 11. Multiple vibration components are rotatably connected to the bottom edge of the assembly base 11, and each vibration component causes the centrifuge cylinder 8 to vibrate. An installation ring 12 is fixedly installed on the top surface of the assembly base 11. Multiple insertion rods 15 are clamped on the top surface of the installation ring 12, and the multiple insertion rods 15 are symmetrically distributed around the center of the centrifuge cylinder 8. Multiple spring telescopic rods 22 are installed on the outer side of each insertion rod 15. A disturbance plate 23 is fixedly installed on the other end of the multiple spring telescopic rods 22 located on the same side. The side of each disturbance plate 23 away from the spring telescopic rod 22 is in contact with the inner wall of the centrifuge cylinder 8, and the two outer sides of each disturbance plate 23 are arc-shaped.

[0026] The centrifuge cylinder 8 is driven to rotate by the drive mechanism, and the separation of coal tar is achieved by centrifugal force. At the same time, the vibration component causes the centrifuge cylinder 8 to vibrate, which can prevent coal tar from accumulating and agglomerating on the inner wall of the centrifuge cylinder 8, thereby improving the separation efficiency. Furthermore, the disturbance plate 23 is attached to the inner wall of the centrifuge cylinder 8 under the action of the spring telescopic rod 22. As the centrifuge cylinder 8 rotates, the disturbance plate 23 can disturb the impurities attached to the inner wall of the centrifuge cylinder 8, causing them to detach from the inner wall of the centrifuge cylinder 8. The arc-shaped design on both sides of the disturbance plate 23 can guide the impurities into the central area of ​​the centrifuge cylinder 8, and then participate in the tar separation again under the action of centrifugal force.

[0027] Furthermore, the drive mechanism includes a drive motor 20, which is fixedly mounted on the inner bottom wall of the mounting base 11. A drive gear 21 is mounted on the outer side of the top output shaft of the drive motor 20, and a gear ring 13 is mounted on the outer side of the centrifuge cylinder 8, and the gear ring 13 meshes with the drive gear 21.

[0028] Furthermore, each vibration component includes a driven gear 14, and each driven gear 14 is rotatably connected in the mounting base 11. Each driven gear 14 meshes with a gear ring 13. The bottom surface of each driven gear 14 is coaxially connected to a rotating shaft 9, and the other end of each rotating shaft 9 is rotatably connected to the bottom wall of the tank 1. Multiple elastic rods 10 are installed on the outside of each rotating shaft 9, and the length of the elastic rods 10 is greater than the distance between the outside of the rotating shaft 9 and the outside of the centrifuge cylinder 8, so that the elastic rods 10 knock the centrifuge cylinder 8 to assist the impurities to fall off.

[0029] Furthermore, the top surface of the mounting ring 12 is provided with multiple positioning grooves 16, and each insertion rod 15 is locked in the corresponding positioning groove 16. Multiple locking pins 18 are elastically slidably connected to the outside of the mounting ring 12, and each locking pin 18 is locked in the insertion rod 15.

[0030] Furthermore, multiple limiting grooves 17 are provided on the outer side of the mounting ring 12, and each locking pin 18 passes through the limiting groove 17 and is locked in the insert rod 15. A limiting spring 19 is installed on one side of each locking pin 18 and the outer side of the mounting ring 12.

[0031] The installation ring 12 is connected to the insertion rod 15 by the locking pin 18, which facilitates the disassembly and maintenance of the insertion rod 15 and the disturbance plate 23, and improves the practicality of the device.

[0032] Furthermore, an electric heating wire 7 is installed inside the side wall of the tank body 1, and the electric heating wire 7 is arranged in a spiral. The electric heating wire 7 inside the side wall of the tank body 1 can heat the coal tar and reduce its viscosity. A top cover 2 is installed on the top surface of the tank body 1, and a feed pipe 5 is installed on the top surface of the top cover 2. An oil discharge pipe 3 is fixed and connected to the outside of the tank body 1. A slag discharge pipe 4 is installed on the bottom surface of the tank body 1, and the slag discharge pipe 4 is connected to the centrifuge cylinder 8. A solenoid valve 6 is installed on the outside of the oil discharge pipe 3, the slag discharge pipe 4 and the feed pipe 5, and the centrifuge cylinder 8 is connected to the slag discharge pipe 4 through a rotary joint.

[0033] In practical use, the working principle of this utility model is as follows:

[0034] First, open the solenoid valve 6 of the feed pipe 5 and inject the coal tar into the centrifuge cylinder 8 through the feed pipe 5. Then close the solenoid valve 6 and start the drive motor 20. Its output shaft drives the drive gear 21 to rotate. The drive gear 21 meshes with the gear ring 13, causing the centrifuge cylinder 8 to rotate between the bottom wall of the tank 1 and the mounting base 11. The coal tar begins to separate under the action of centrifugal force.

[0035] At the same time, the gear ring 13 drives the driven gear 14 to rotate, and the driven gear 14 drives the rotating shaft 9 to rotate. The elastic rod 10 on the rotating shaft 9, because its length is greater than the distance from the rotating shaft 9 to the outside of the centrifuge tube 8, continuously strikes the outer wall of the centrifuge tube 8, causing it to vibrate.

[0036] During centrifugation, impurities adhere to the inner wall of the centrifuge cylinder 8 under centrifugal force. The disturbance plate 23 adheres to the inner wall under the action of the spring telescopic rod 22. As the centrifuge cylinder 8 rotates, it pushes the adhered impurities away from the inner wall. The arc-shaped sides guide the impurities to the central area of ​​the centrifuge cylinder 8. These impurities are remixed into the coal tar and participate in the separation again under the action of centrifugal force, thus improving the thoroughness of the separation.

[0037] Meanwhile, during the operation of the device, the heating wire 7 heats and reduces the viscosity of the coal tar. The separated oil is discharged through the oil discharge pipe 3, and the residue is discharged through the slag discharge pipe 4 connected to the centrifuge 8 via a rotary joint. During maintenance, the locking pin 18 is pulled out to remove the insertion rod 15, and components such as the disturbance plate 23 can be inspected.

[0038] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
