Description

Technical Field

[0001] This utility model relates to the technical field of separation equipment in coking production, and in particular to a coal coking tar residue separation device. Background Technology

[0002] Coking plants generate large quantities of tar mixtures during the coking process. Currently, the tar mixture is typically separated into tar residues by static separation, with tar on top and tar residues on the bottom. However, this method is time-consuming, impacting subsequent chemical production in the coking oven. Furthermore, the upper tar layer still contains a small amount of tar residue, leading to blockages during transport, increasing worker workload, and affecting subsequent production efficiency. Therefore, this application proposes a coal coking tar residue separation device for efficient tar residue separation. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a coal coking tar residue separation device. The technical solution it solves is as follows: it includes an outer cylinder, characterized in that a support is fixedly connected to the top of the outer cylinder, a driving device is arranged on the support, the driving device is connected to a centrifuge cylinder arranged coaxially with the outer cylinder, a plurality of centrifuge grooves are evenly distributed around the outer edge of the centrifuge cylinder, a filter cloth is fixedly installed on the outer edge of the centrifuge cylinder, a displacement device is also arranged on the support, the displacement device is connected to a brush handle, and a plurality of bristles are evenly distributed on the end of the brush handle facing the filter cloth.

[0004] The displacement device includes two support plates arranged laterally and fixedly connected to the bracket. The two support plates are rotatably connected to the opposite ends of a horizontally arranged lead screw. The two support plates are also fixedly connected to the opposite ends of a horizontal shaft. The horizontal shaft is slidably connected to a displacement rod that is threadedly connected to the lead screw. The displacement rod is detachably connected to the upper end of the brush handle.

[0005] A slag discharge device is arranged at the bottom of the centrifuge cylinder, and a material discharge device is arranged at the bottom of the outer cylinder.

[0006] Preferably, the driving device includes a drive motor fixedly connected to the bracket, and the output shaft flange of the drive motor is connected to the upper end of the centrifuge cylinder.

[0007] Preferably, a connecting frame is integrally and coaxially arranged on the upper end of the centrifuge tube, and a docking shaft is coaxially and fixedly connected to the connecting frame. The docking shaft is connected to the output shaft flange of the drive motor.

[0009] Preferably, the discharge device includes a discharge pipe that is coaxially arranged with and integrally connected to the bottom of the outer cylinder, and a discharge valve is installed on the discharge pipe.

[0010] Preferably, a handwheel is coaxially fixedly connected to the right end of the lead screw.

[0011] The beneficial effects of this utility model are:

[0012] In use, this application involves introducing a certain amount of tar to be separated into a centrifuge drum. Driven by a driving device, the centrifuge drum rotates at high speed, generating centrifugal force. This force causes the tar to pass through the filter cloth outside the centrifuge tank and be thrown into the outer drum, while the tar residue remains trapped in the centrifuge drum due to the filter cloth's obstruction, thus achieving separation. Furthermore, after separation, to prevent tar residue from adhering to the filter cloth and causing blockage, a displacement device moves the brush handle closer to the filter cloth, causing the bristles to contact the cloth. Simultaneously, while the centrifuge drum rotates, the operator can rinse the filter cloth with water to prevent blockage. During cleaning, both the slag discharge and material discharge devices can be opened to remove the tar residue. This application features a simple structure, ease of use, and strong practicality.

[0020] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0021] In the first embodiment, the technical solution is as follows: During use, a certain amount of tar requiring separation is introduced into the centrifuge drum 4. Under the action of the drive device 3, the centrifuge drum 4 can rotate at high speed. This high-speed rotation generates centrifugal force, causing the tar to be thrown into the outer drum 1 through the filter cloth 6 outside the centrifuge tank 5. The tar residue, however, remains in the centrifuge drum 4 due to the obstruction of the filter cloth 6, thus achieving separation. Further, after separation, to prevent tar residue from adhering to the filter cloth 6 and causing blockage, a displacement device is used to move the brush handle 7 closer to the filter cloth 6, causing the brush bristles 8 to abut against the filter cloth 6. Then, while the centrifuge drum 4 rotates via the drive device 3, the operator can rinse the filter cloth 6 with water to prevent blockage. During cleaning, the slag discharge device 13 and the material discharge device 14 can be opened simultaneously to discharge the tar residue.

[0022] In Example 2, based on Example 1, specifically, during use, a certain amount of tar to be separated is transported from the upper end of the centrifuge cylinder 4 into the centrifuge cylinder 4. Then, the drive motor 15 of the drive device 3 on the support 2 is started. The start of the drive motor 15 drives the docking shaft 18 to rotate through its output shaft 16. Consequently, the connecting frame 17, which is fixedly connected to the docking shaft 18, and the centrifuge cylinder 4 will rotate synchronously. The rotation of the centrifuge cylinder 4 will generate centrifugal force, which will throw the tar in the centrifuge cylinder 4 outward, allowing the tar to enter the filter cylinder through the centrifuge tank 5 and the filter cloth 6, while the tar residue is blocked in the centrifuge cylinder 4, thus completing the separation of tar and tar residue. The separation is thorough and efficient. After the separation is completed, the drive device 3 is turned off and the discharge valve 24 of the discharge device 14 is opened, thereby discharging the tar in the outer cylinder 1.

[0023] In Example 3, based on Example 2, after the tar in the outer cylinder 1 is separated and discharged, a displacement device is provided to facilitate cleaning of the filter cloth 6 to prevent tar residue from adhering to the filter cloth 6 and causing blockage. During cleaning, the lead screw 10 on the support plate 9 is rotated clockwise. A handwheel 25 is provided to facilitate the rotation of the lead screw 10. The clockwise rotation of the lead screw 10 drives the displacement rod 12 to move to the right along the horizontal axis 11 (i.e., move closer to the centrifuge cylinder 4). The brush handle 7 connected to the displacement rod will then move closer to the centrifuge cylinder 4 until the bristles 8 on the brush handle 7 abut against the filter cloth 6 on the outside of the centrifuge cylinder 4. Then, the drive motor 15 is started to drive the centrifuge cylinder 4 to rotate. At the same time, the operator needs to hold a water hose to rinse the filter cloth 6. The bristles 8 can clean the filter cloth 6 on the outside of the rotating centrifuge cylinder 4, thereby washing away the tar residue adhering to the filter cloth 6. The filter cloth 6 is thin, so the bristles 8 can be effectively cleaned even when the filter cloth 6 is on the outside.

[0024] During cleaning, the slag discharge device 13 should also be opened. Specifically, the operating rod 21 is rotated by the operating ring 22, thereby unscrewing the baffle 20 out of the threaded hole 19, so that the flushed tar slag can be discharged from the threaded hole 19 into the outer cylinder 1. At the same time, the discharge valve 24 should also be opened so that the tar slag entering the outer cylinder 1 can be discharged from the discharge pipe 23. The displacement rod 12 and the brush handle 7 are detachably connected by bolts for maintenance and replacement.
