Description

Technical Field

[0001] This utility model relates to the field of tar residue recycling technology, and in particular to a centrifuge device for tar residue recycling. Background Technology

[0002] Centrifuges for tar residue recycling are industrial equipment specifically designed for separating and recycling oil, moisture, and solid impurities from tar residue. They are mainly used in industries such as coal chemical, petroleum refining, and coking. Their core function is to efficiently separate different components in tar residue through centrifugal force, thereby achieving resource recovery and environmentally friendly treatment.

[0003] Existing centrifuges for tar residue recovery have relatively simple discharge port structures, usually using a straight-through or simple conical design, lacking anti-clogging structures. Due to the high viscosity and easy solidification of tar residue, it is easy to accumulate at the discharge port after long-term operation, leading to pipe blockage and affecting continuous production.

[0004] Therefore, in view of the problem that the existing centrifuges for tar residue recycling have a simple slag outlet structure and lack anti-clogging structure, and that the viscous tar residue easily clogs the pipes after long-term use, a centrifuge for tar residue recycling equipment can be designed. Utility Model Content

[0005] In order to overcome the problem that the existing centrifuges for tar residue recovery have a simple slag outlet structure and lack anti-clogging structure, which makes the pipes easy to be blocked by viscous tar residue after long-term use.

[0006] The technical solution of this utility model is as follows: a centrifuge for tar residue recovery, including a horizontal screw centrifuge body; it also includes scrapers and a drive assembly. A first slag discharge pipe is installed at the bottom slag discharge port of the horizontal screw centrifuge body. A fixed frame is set at the bottom of the first slag discharge pipe. A second slag discharge pipe is installed at the bottom of the fixed frame. A positioning ring is installed on the inner bottom surface of the fixed frame. A toothed ring is rotatably connected to the top of the positioning ring through a slider. Two fixed plates are installed on the inner side of the toothed ring. Scrapers are installed on the left and right sides of the two fixed plates. A drive assembly is set at the bottom of the fixed frame to drive the toothed ring to rotate. A linkage assembly is set on the top right side of the fixed frame.

[0007] Preferably, by setting a drive component, the gear ring can be driven to rotate during operation. When the gear ring rotates, it can drive the fixed plate to rotate synchronously. The scrapers on both sides of the fixed plate are respectively in contact with the inner walls of the corresponding first and second slag discharge pipes. Thus, when the fixed plate rotates, it can drive the scrapers to clean the inner walls of the first and second slag discharge pipes, avoiding the problem of tar residue sticking to the inner wall of the discharge port when discharged, which is prone to blockage after long-term use. This solves the problem that the existing centrifuges for tar residue recycling have a relatively simple discharge port structure and lack anti-blocking structure, which makes the pipes easy to be blocked by viscous tar residue after long-term use.

[0008] Preferably, the drive assembly includes a drive motor and a transmission gear; the drive motor is mounted on the bottom right side of the fixed frame, and the output end of the drive motor is connected to the transmission gear, which is used to drive the transmission gear to rotate.

[0009] Preferably, the drive assembly also includes a belt; the gear ring and the transmission gear are fitted with a belt on their outer sides, and the gear ring is linked to the transmission gear through the belt.

[0010] Preferably, the linkage assembly includes a connecting shaft and a first bevel gear; the connecting shaft is mounted on the top of the transmission gear, and the first bevel gear is mounted on the top of the connecting shaft.

[0011] Preferably, the linkage assembly also includes a mounting plate, a support base, a bearing, and a drive shaft; the mounting plate is provided on the top right side of the fixed frame, the support base is mounted on the top of the mounting plate, the bearing is embedded inside the support base, and the drive shaft is mounted on the inner side of the bearing.

[0012] Preferably, the linkage assembly also includes a second bevel gear; the second bevel gear is installed at the left end of the drive shaft, and the second bevel gear meshes with the first bevel gear, and the second bevel gear is used to drive the first bevel gear to rotate.

[0013] Preferably, the linkage assembly also includes a docking seat and a slot; the right end of the drive shaft is equipped with a docking seat, and the right end of the docking seat has a slot, which is a regular hexagon.

[0014] The beneficial effects of this utility model are:

[0015] By incorporating a rotatable scraper, the problem of easy clogging in the discharge pipe of the horizontal screw centrifuge can be effectively solved. This design utilizes the dynamic rotational mechanical action to continuously remove tar residue deposits adhering to the pipe wall, ensuring that the discharge channel remains unobstructed and that the tar residue is discharged in a timely and thorough manner. At the same time, the continuous cleaning action of the rotating scraper avoids the problem of pipe diameter narrowing caused by slag accumulation, significantly reducing the frequency of manual unclogging and maintenance. This technology effectively extends the continuous operation cycle of the equipment and ensures the stability of the production system. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a centrifuge for tar residue recovery, including a horizontal screw centrifuge body 1; it also includes a scraper 8 and a drive assembly. A first discharge pipe 2 is installed at the bottom discharge port of the horizontal screw centrifuge body 1. A fixed frame 3 is provided at the bottom of the first discharge pipe 2. A second discharge pipe 4 is installed at the bottom of the fixed frame 3. A positioning ring 5 is installed on the inner bottom surface of the fixed frame 3. A toothed ring 6 is rotatably connected to the top of the positioning ring 5 through a slider. Two fixing plates 7 are installed on the inner side of the toothed ring 6. The two fixing plates 7 are positioned on the left and right sides. Scrapers 8 are installed on both sides. A drive assembly is set at the bottom of the fixed frame 3 to drive the toothed ring 6 to rotate. A linkage assembly is set on the top right side of the fixed frame 3. The toothed ring 6 is driven to rotate through the drive assembly. The toothed ring 6 drives the fixed plate 7 to rotate synchronously. The scrapers 8 installed on both sides of the fixed plate 7 are close to the inner walls of the first slag discharge pipe 2 and the second slag discharge pipe 4 respectively. During the rotation, they continuously scrape off the tar residue attached to the pipe wall. This design effectively prevents the tar residue from sticking to the inner wall of the discharge port during the discharge process and solves the problem of pipe blockage caused by long-term operation.

[0024] Please see Figures 3-5In this embodiment, the drive assembly includes a drive motor 91 and a transmission gear 92. The drive motor 91 is installed on the bottom right side of the fixed frame 3. The output end of the drive motor 91 is connected to the transmission gear 92. The drive motor 91 is used to drive the transmission gear 92 to rotate. By setting the drive motor 91, its output end can drive the transmission gear 92 to rotate during operation. The drive assembly also includes a belt 93. The gear ring 6 and the transmission gear 92 are sleeved with the belt 93. The gear ring 6 is linked with the transmission gear 92 through the belt 93. By setting the belt 93, the transmission gear 92 drives the gear ring 6 to rotate through the linkage of the belt 93 when rotating, thereby achieving the purpose of automatically cleaning the first slag discharge pipe 2 and the second slag discharge pipe 4. The linkage assembly includes a connecting shaft 101 and a first bevel gear 102. The connecting shaft 101 is installed on the top of the transmission gear 92. The first bevel gear 102 is installed on the top of the connecting shaft 101. By setting the first bevel gear 102, the first bevel gear 102 can drive the transmission gear 92 to rotate through the connecting shaft 101 when rotating.

[0025] Please see Figures 3-5 In this embodiment, the linkage assembly further includes a mounting plate 103, a support base 104, a bearing 105, and a drive shaft 106. A mounting plate 103 is provided on the top right side of the fixed frame 3. A support base 104 is mounted on the top of the mounting plate 103. A bearing 105 is embedded inside the support base 104, and a drive shaft 106 is mounted inside the bearing 105. By providing the support base 104 for mounting the bearing 105, the bearing 105 can assist the drive shaft 106 in rotating, improving the stability of the drive shaft 106's rotation. The linkage assembly also includes a second bevel gear 107. A second bevel gear 107 is mounted on the left end of the drive shaft 106, and the second bevel gear 107 interacts with the first... A first bevel gear 102 meshes with a second bevel gear 107, which drives the first bevel gear 102 to rotate. By setting the second bevel gear 107, the second bevel gear 107 can drive the first bevel gear 102 meshing with it to rotate when it rotates. The linkage component also includes a docking seat 108 and a slot 109. The docking seat 108 is installed on the right end of the drive shaft 106, and a slot 109 is opened on the right end of the docking seat 108. The slot 109 is a regular hexagon. By setting the docking seat 108 and the slot 109, if the drive motor 91 fails, the operator can insert the rocker arm into the inner wall of the slot 109 to rotate the drive shaft 106, thereby driving the gear ring 6 to rotate through the linkage between the components.

[0026] During slag discharge, the drive motor 91 outputs torque to the transmission gear 92, causing the transmission gear 92 to rotate. Through the linkage of the belt 93, the gear ring 6 rotates synchronously. The gear ring 6 is rigidly connected to the fixed plate 7, so that the fixed plate 7 rotates together with the gear ring 6. During the rotation of the fixed plate 7, the scraper 8 can effectively remove the slag adhering to the inner wall of the first slag discharge pipe 2 and the second slag discharge pipe 4. In the abnormal working condition of drive motor 91 failure, the operator can insert the rocker arm into the slot 109 at the end of the transmission shaft 106 to apply an external torque to the transmission shaft 106. This torque is transmitted to the second bevel gear 107 through the transmission shaft 106. Through the meshing of the second bevel gear 107 and the first bevel gear 102, the rotational motion is converted into the rotation of the connecting shaft 101, which ultimately drives the transmission gear 92 to rotate, thereby realizing the emergency operation function of manual unblocking.

[0027] Through the above steps, by setting up a drive component, when the drive component is started, it will drive the toothed ring 6 to rotate. The rotation of the toothed ring 6 will be transmitted synchronously to the fixed plate 7. Scrapers 8 are installed on both sides of the fixed plate 7. These two scrapers 8 are in close contact with the inner walls of the first slag discharge pipe 2 and the second slag discharge pipe 4, respectively. When the fixed plate 7 rotates with the toothed ring 6, the scrapers 8 will move circumferentially along the inner wall of the slag discharge pipe, thereby continuously scraping off the tar residue attached to the pipe wall. This dynamic cleaning mechanism ensures that the tar residue will not accumulate on the inner wall during the discharge process, fundamentally avoiding the problem of slag discharge pipe blockage caused by long-term operation. This solves the problem that the existing centrifuges for tar residue recycling have a relatively simple slag outlet structure and lack anti-clogging structure, and that the viscous tar residue easily blocks the pipes after long-term use.
