Description

Technical Field

[0001] This utility model relates to the field of settling tank technology, specifically a tar settling tank. Background Technology

[0002] Mechanized tar-ammonia clarification tanks are a type of primary cooling equipment for coke oven gas that uses gravity settling to separate coal tar, ammonia, and tar residue. The tank cross-section is available in both boat-shaped and rectangular shapes. Mechanized ammonia clarification tanks are used by gas companies or coking plants to purify tar, primarily separating tar, ammonia, and tar residue based on the different specific gravities of the materials.

[0003] According to a public notice (Announcement No.: CN217409824U) regarding a tar and ammonia water clarification tank tar recovery device, the clarification tank is divided into three layers: the upper layer is ammonia water, the middle layer is tar, and the lower layer is tar residue. The tar residue settled at the bottom of the tank is sent to the discharge nozzle by a scraper conveyor and discharged from the tank. The tar flows to the tar tank through a liquid level regulator. The clarified ammonia water overflows from the top to the circulating ammonia water tank. When discharging slag from the clarification tank, since the upper layer of tar residue is tar, the tar residue itself will carry a small amount of tar along with it and be sent to the discharge nozzle by the scraper conveyor and discharged.

[0004] However, in actual use, although the above-mentioned equipment can remove the oil residue from the settling tank, a large amount of oil adheres to the conveyor belt during the removal process, which leads to the problem of the oil residue rolling off and accumulating poorly for discharge. In view of this, we propose a tar settling tank. Utility Model Content

[0005] The purpose of this invention is to provide a tar settling tank to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tar settling tank, comprising a settling chamber, an external ammonia water layer pipe assembly and an external tar layer pipe assembly, an input pipe, and a settling removal assembly on the inner wall of the settling chamber. The settling removal assembly includes a threaded rotating rod threadedly connected to the inner wall of the settling chamber, a lifting chamber rotatably mounted at the end of the threaded rotating rod, a limit rod fixedly connected to the outer wall of the lifting chamber, a motor fixedly connected to the outer wall of the lifting chamber, and a reciprocating screw fixedly connected to the output end of the motor through the lifting chamber. A slider is slidably connected to the outer wall of the reciprocating screw. A connecting plate is fixedly connected to the outer wall of the slider. A mounting bracket is fixedly connected to the end of the connecting plate. A scraper is fixedly connected to the bottom end of the mounting bracket. A collection chamber is detachably installed on the outer wall of the settling chamber. Bolts are threadedly connected to the inner wall of the collection chamber. A filter plate is fixedly connected to the bottom end of the lifting chamber.

[0007] Preferably, the connecting plate is slidably connected to the inner wall of the lifting chamber, and the outer wall of the connecting plate is adapted to the inner wall of the lifting chamber.

[0008] Preferably, the number of collection chambers is two sets, and the two sets of collection chambers are arranged on both sides of the center plane of the settling chamber.

[0009] Preferably, the centerline of the lifting chamber and the centerline of the settling chamber are all on the same straight line as the centerline of the threaded rotating rod.

[0010] Preferably, the outer wall of the collection chamber is provided with a shaking component, the shaking component includes a protrusion, the protrusion is fixedly connected to the outer wall of the collection chamber, and an arc-shaped ball is fixedly connected to the outer wall of the protrusion.

[0011] Preferably, the number of the arc-shaped spheres is several, and the several arc-shaped spheres are arranged in a linear array on the outer wall of the protrusion.

[0012] Preferably, the outer wall of the arc-shaped ball is adapted to the outer wall of the scraper, so that the scraper can be rubbed by the arc-shaped ball when it is displaced, and the tar residue attached to the scraper can be better removed through vibration.

[0013] Compared with the prior art, the present invention provides a tar settling tank, which has the following beneficial effects: 1. In daily use, the tar settling tank can convey materials to the settling chamber through the inlet pipe. After sedimentation, the upper layer is ammonia water, the middle layer is tar, and the lower layer is tar residue. The tar is discharged through the external tar layer pipe assembly, and the ammonia water is discharged through the external ammonia water layer pipe assembly. When discharging the tar residue, the threaded rod can be rotated to raise the lifting chamber to its maximum limit. Then, the motor is started to drive the reciprocating screw to rotate, which causes the limited slider to move the mounting bracket and scraper on the connecting plate. This allows the scraper to push out the accumulated and settled tar residue on the filter plate, so that the tar residue can be steadily collected into the collection chambers on both sides, preventing the problem of insufficient tar residue discharge.

[0014] 2. The tar settling tank, through the setting of protrusions and arc-shaped balls, can periodically squeeze and touch the scraper when the scraper moves left and right, so that when the scraper is touched and vibrates, the tar residue attached to the surface can be better removed through vibration, which ensures the effectiveness of the scraper in removing residue and further improves the overall practicality.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a tar settling tank, including a settling chamber 1, an external ammonia water layer pipe assembly 2 and an external tar layer pipe assembly 6 on the outer wall of the settling chamber 1, an input pipe 3 on the outer wall of the settling chamber 1, and a settling removal component 4 on the inner wall of the settling chamber 1. The settling removal component 4 includes a threaded rotating rod 401, which is threadedly connected to the inner wall of the settling chamber 1. A lifting chamber 402 is rotatably installed at the end of the threaded rotating rod 401. A limit rod 412 is fixedly connected to the outer wall of the lifting chamber 402. A motor 403 is fixedly connected to the outer wall of the lifting chamber 402. A reciprocating screw 404 is fixedly connected to the output end of the motor 403 through the lifting chamber 402. A slider 405 is slidably connected to the outer wall of the reciprocating screw 404.

[0018] Furthermore, the connecting plate 406 is fixedly connected to the outer wall of the slider 405, the end of the connecting plate 406 is fixedly connected to the mounting bracket 407, the bottom end of the mounting bracket 407 is fixedly connected to the scraper 408, the outer wall of the settling chamber 1 is detachably installed with the collection chamber 409, the inner wall of the collection chamber 409 is threadedly connected with the bolt 410, and the bottom end of the lifting chamber 402 is fixedly connected to the filter plate 411.

[0019] In an embodiment of this utility model, the connecting plate 406 is slidably connected to the inner wall of the lifting chamber 402, and the outer wall of the connecting plate 406 is adapted to the inner wall of the lifting chamber 402. The number of collection chambers 409 is two sets, and the two sets of collection chambers 409 are mirror images of the center plane of the settling chamber 1 on both sides. The center line of the lifting chamber 402 and the center line of the settling chamber 1 are on the same straight line as the center line of the threaded rotating rod 401.

[0020] Furthermore, the outer wall of the collection chamber 409 is provided with a shaking component 5, which includes a protrusion 501. The protrusion 501 is fixedly connected to the outer wall of the collection chamber 409. An arc-shaped ball 502 is fixedly connected to the outer wall of the protrusion 501. The number of arc-shaped balls 502 is several, and the arc-shaped balls 502 are arranged in a linear array on the outer wall of the protrusion 501. The outer wall of the arc-shaped ball 502 is adapted to the outer wall of the scraper 408, so that the scraper 408 can be rubbed by the arc-shaped ball 502 when it is displaced, and the tar residue attached to the scraper 408 can be better removed through vibration.

[0021] In this utility model, during daily use, materials can be conveyed to the settling chamber 1 through the input pipe 3. After sedimentation, the upper layer is ammonia water, the middle layer is tar, and the lower layer is tar residue. The tar is discharged through the external tar layer pipe group 6, and the ammonia water is discharged through the external ammonia water layer pipe group 2. When discharging the tar residue, the threaded rotating rod 401 can be rotated to raise the lifting chamber 402 to the maximum limit. Then, the motor 403 is started to drive the reciprocating screw 404 to rotate, so that the limited slider 405 can drive the mounting bracket 407 and scraper 408 on the connecting plate 406 to move. As a result, when the scraper 408 moves, it can push out the tar residue accumulated and settled on the filter plate 411, so that the tar residue can be steadily collected into the collection chambers 409 on both sides, preventing the problem of insufficient tar residue discharge.

[0022] The protrusion 501 and the arc ball 502 can periodically press and touch the scraper 408 when it moves left and right back and forth. This allows the scraper 408 to vibrate under pressure, which in turn allows the tar residue attached to the surface to fall off better. This ensures the scraper 408 can effectively remove residue and further improves its overall practicality.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
