Description

Technical Field

[0001] This invention belongs to the technical field of high viscosity material separation devices, and specifically relates to an anti-clogging device for high viscosity material separation devices. Background Technology

[0002] Some high-viscosity material separation devices use gravity sedimentation to separate high-viscosity solids and liquids, such as tar separation devices for coal gas and water, coal dust and water separation devices, and sludge solid-liquid separation devices. After separation, the liquid is discharged, while the solid, due to its high viscosity, is prone to clogging and cannot be discharged.

[0003] Existing gas-water separators typically use a main shaft and scraper to scrape off the dust-laden tar from the inner wall of the lower casing to prevent its accumulation. However, the drive components of the main shaft are usually located at the top of the separator. Therefore, the lower agitator may become stuck or stop operating due to the excessive length of the main shaft, causing dust and tar to accumulate at the bottom of the separator and preventing normal discharge. Over time, this severely encroaches on the internal separation space of the primary tar, leading to fluctuations in the gas-water quality and the inability to collect clean tar.

[0004] Chinese patent CN217126988U discloses a gas-water primary tar separation device, which uses a lower independent drive unit instead of an upper drive method to avoid the main shaft running through the entire housing. However, in the long-term use of the above solution, dust-containing tar and tar residue are easy to accumulate at the bottom of the separation device and are not easy to flow out. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-clogging device for a high-viscosity material separation device, which can stir high-viscosity materials and facilitate their discharge.

[0013] The top surface of the support base is recessed; the bottom of the stirring shaft is inserted into the recess of the support base and placed inside the support base; the lifting rod is fixed to the bottom of the support base, and the bottom of the lifting rod is provided with external threads; the top surface of the rotating seat is recessed, and the interior is provided with internal threads; the bottom of the lifting rod is inserted into the rotating seat and cooperates with the rotating seat; the bottom of the rotating seat is inserted into the base; a first gear is fixed on the rotating seat; the first gear meshes with a second gear; the lifting motor is connected to a first motor shaft; the first motor shaft is connected to the second gear.

[0014] Preferably, the drive mechanism includes a drive motor, a third gear, and a fourth gear; the drive motor is connected to a second motor shaft; the second motor shaft is connected to the third gear; the third gear and the fourth gear mesh with each other; the fourth gear is mounted on the stirring shaft; and the thickness of the fourth gear is greater than that of the third gear.

[0015] Preferably, a torque sensor is mounted on the second motor shaft.

[0016] Preferably, the stirring shaft is mounted in the housing via a bearing seat; the oil injection hole of the bearing seat is connected to an oil injection pipe; the oil injection pipe passes through the housing and is connected to an oil injection gun, so that when the bearing seat seal fails, the oil injection gun delivers oil to the bearing seat.

[0017] Preferably, the oil injection gun includes a gun body; a nozzle is connected to one end of the gun body; the nozzle is connected to an oil injection pipe; a first piston and a second piston are provided inside the gun body; a spring is provided between the first piston and the second piston; a screw is fixed to the side of the second piston away from the nozzle; the screw extends outward through the gun body; the screw is threadedly connected to the gun body; and an observation window is installed on the gun body.

[0018] The present invention also provides a high-viscosity material separation device, including a cylinder and the aforementioned anti-clogging device, wherein the cylinder is installed at the top of a cone; a conical baffle is provided inside the cylinder; a connecting hole is provided on the conical baffle; a balance pipe is connected to the connecting hole; one end of the balance pipe away from the conical baffle extends obliquely upward and communicates with the outer side of the cylinder.

[0019] The present invention provides an anti-clogging device for a high-viscosity material separation apparatus, which has the following advantages compared with the prior art:

[0020] (1) The high-viscosity material inside the shell is stirred by the stirring frame to make the high-viscosity material flow, prevent it from accumulating and being unable to be discharged.

[0021] (2) By using the drum-shaped gear coupling, the swaying and shaking of the stirring shaft can be reduced, the damage to the stirring shaft can be avoided, and the failure rate of the stirring shaft and the drive mechanism can be greatly reduced.

[0022] (3) The lifting mechanism can make the stirring shaft, stirring frame, main shaft and rotating frame rise synchronously, reduce resistance, keep the load of the stirring shaft stable, and improve the reliability and stability of the system.

[0023] (4) The torque of the stirring shaft and the main shaft is detected by the torque sensor. When the torque detected by the torque sensor is too large, it indicates that too much high-viscosity material has accumulated in the shell and the discharge is slow. At this time, the material to be separated entering the separation device should be reduced or stopped, and / or the lifting mechanism should be started, and / or the drive motor should be reversed. Various methods should be used to avoid damaging the stirring shaft and the drive motor until the torque returns to normal.

[0024] (5) The spring maintains positive pressure in the oil injection pipe. When the bearing seat seal fails, the pressure on the spring decreases, and the spring pushes the gun body grease into the oil injection pipe and then into the bearing seat. This prevents high-viscosity materials from entering the bearing seat and contaminating or damaging the bearing seat and the stirring bearing. The separation equipment stops, and maintenance personnel repair the bearing seat. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] like Figure 1-3 As shown, an anti-clogging device is used in a high-viscosity material separation device.

[0034] The anti-clogging device includes a cone 2 and a stirring mechanism 3.

[0035] The cone 2 is inverted cone shape and is installed at the bottom of the high-viscosity material separation device. The high-viscosity material separated by the high-viscosity material separation device falls into the cone 2. The high-viscosity material separation device can be a gas-water separation device or other separation devices. The cone 2 is hollow cone shape and has a main shaft 21 and a rotating frame 22 inside. The rotation of the main shaft 21 drives the rotating frame 22 to rotate. A scraper 23 is installed on the rotating frame 22 to scrape off the high-viscosity material adhering to the inner wall of the cone 2.

[0036] The stirring mechanism 3 includes a housing 31, a stirring shaft 32, and a tray 33. The housing 31 has an open top and is connected to the bottom of the cone 2 via a flange 311. A discharge port 312 is provided at the bottom of the side wall of the housing 31 to discharge high-viscosity materials from inside the housing 31. The stirring shaft 32 is mounted in the housing 31 via a bearing seat 321, and a drive mechanism is connected to the bottom of the housing 31 to drive the stirring shaft 32 to rotate. The drive mechanism is driven by a drive motor 5. The tray 33 is disposed inside the cone 2. The main shaft... The bottom of the rotating frame 21 passes through the tray 33 and is connected to the stirring shaft 32 via a coupling 34. The top of the coupling 34 is connected to the bottom of the tray 33 via a flange. The bottom of the rotating frame 22 can be fixed on the tray 33. A stirring frame 35 is fixed to the bottom of the tray 33. The stirring frame 35 extends into the housing 31. When the drive mechanism drives the stirring shaft 32 to rotate, the stirring shaft 32 drives the main shaft 21 to rotate, and the tray 33 rotates accordingly, causing the stirring frame 35 to rotate. The stirring frame 35 stirs the high-viscosity material in the housing 31, making the high-viscosity material flow, preventing accumulation, and preventing it from being discharged.

[0037] In this embodiment, the stirring frame 35 is an annular frame structure, the stirring shaft 32 is inside the stirring frame 35, and the stirring frame 35 rotates around the stirring shaft 32; the stirring frame 35 is fixed with multiple scrapers 351; the scrapers 351 correspond to the inner wall of the shell 31, and when the stirring frame 35 rotates, the scrapers 351 can conveniently stir the high-viscosity material and scrape off the high-viscosity material from the inner wall of the shell 31. The stirring frame 35 is composed of multiple vertical stirring rods and connecting rods, and the connecting rods connect the multiple stirring rods in an annular shape. Each stirring rod can be fixed with a corresponding scraper 351.

[0038] In this embodiment, as Figure 3As shown, the side wall of the housing 31 is provided with a detection port 313. When the equipment is stopped, the detection port 313 is opened to facilitate the inspection and maintenance of the stirring shaft 32, coupling 34 and other equipment.

[0039] Example 2

[0040] The coupling 34 is a drum-shaped gear coupling. During the scraping of high-viscosity materials by the scraper 23 on the rotating frame 22, the rotating frame 22 will swing and shake, which will cause the main shaft 21 to swing and shake, damaging the stirring shaft 32 at the bottom. The drum-shaped gear coupling can reduce the swinging and shaking of the stirring shaft 32, avoid damage to the stirring shaft 32, and greatly reduce the failure rate of the stirring shaft 32 and the drive mechanism. Other features are the same as in Embodiment 1.

[0041] Example 3

[0042] like Figure 4 As shown, the bottom of the stirring shaft 32 is provided with a lifting mechanism, which includes a support base 41, a lifting rod 42, a rotating base 43, a base 44, and a lifting motor 45.

[0043] The top surface of the support base 41 is recessed; the bottom of the stirring shaft 32 is inserted into the recess of the support base 41 and placed inside the support base 41 by a bearing. The support base 41 supports the stirring shaft 32, which can rotate within the support base 41; the lifting rod 42 is fixed to the bottom of the support base 41, and the bottom of the lifting rod 42 is provided with external threads; the top surface of the rotating seat 43 is recessed, and the interior is provided with internal threads; the bottom of the lifting rod 42 is inserted into the rotating seat 43 and cooperates with the rotating seat 43. When the rotating seat 43 rotates, the lifting rod 42 moves up and down through the threads; The bottom of the rotating seat 43 is inserted into the base 44 and is limited by the base 44; a first gear 431 is fixed on the rotating seat 43; the first gear 431 meshes with a second gear 452; the lifting motor 45 is connected to a first motor shaft 451; the first motor shaft 451 is connected to the second gear 452, and the second gear 452 is driven to rotate by the lifting motor 45, thereby causing the first gear 431 to rotate, the rotating seat 43 to rotate accordingly, the lifting rod 42 to rise, the jacking support seat 41 to rise, and the stirring shaft 32 to rise accordingly. Other features are the same as in Embodiment 1.

[0044] As high-viscosity materials accumulate, such as dust-laden tar in coal gas water, the resistance of the rotating frame 22 and the stirring frame 35 constantly changes. In severe cases, this can lead to the burnout of the drive motor 5 and damage to the stirring shaft 32. The lifting mechanism allows the stirring shaft 32, stirring frame 35, main shaft 21, and rotating frame 22 to rise synchronously, reducing resistance, maintaining a stable load on the stirring shaft 32, and improving the reliability and stability of the system. The lifting motor 45 drives the stirring shaft 32 to rise and fall. Compared to a hydraulic cylinder, which only needs to rise a short distance, a hydraulic cylinder can result in a faster rise and makes it difficult to control the rising distance. The lifting motor 45 allows for precise control of the stirring shaft 32's rising distance.

[0045] In this embodiment, the driving mechanism includes a drive motor 5, a third gear 322, and a fourth gear 52. The drive motor 5 is connected to a second motor shaft 51, and the drive motor 5 is fixed to one side below the housing 31. The second motor shaft 51 is connected to the third gear 322. The third gear 322 and the fourth gear 52 mesh with each other. The fourth gear 52 is mounted on the stirring shaft 32. The thickness of the fourth gear 52 is greater than that of the third gear 322. When the stirring shaft 32 rises, the fourth gear 52 rises accordingly. Because the thickness of the fourth gear 52 is greater than that of the third gear 322, the third gear 322 and the drive motor 5 are fixed, and the third gear 322 and the fourth gear 52 will not disengage.

[0046] Example 4

[0047] A torque sensor 53 is installed on the second motor shaft 51. The torque sensor 53 detects the torque of the stirring shaft 32 and the main shaft 21. When the torque detected by the torque sensor 53 is too large, it indicates that too much high-viscosity material has accumulated in the housing 31 and is discharged slowly. At this time, the amount of material to be separated entering the separation device should be reduced or stopped, and / or the lifting mechanism should be started, and / or the drive motor 5 should be reversed. Various methods should be used to avoid damaging the stirring shaft 32 and the drive motor 5 until the torque returns to normal. Other features are the same as in Embodiments 1 and 3.

[0048] Example 5

[0049] The oil injection hole of the bearing housing 321 is connected to an oil injection pipe, which is used to supply grease to the stirring bearing inside the bearing housing 321. The oil injection pipe passes through the housing 31 and is connected to the oil injection gun. The oil injection pipe maintains positive pressure. When the seal of the bearing housing 321 fails, the oil injection gun automatically supplies oil to the bearing housing 321 to prevent high-viscosity materials from entering the bearing housing 321 and contaminating or damaging the bearing housing 321 and the stirring bearing, until the separation equipment stops and maintenance personnel repair the bearing housing 321.

[0050] In this embodiment, as Figure 5As shown, the grease gun includes a gun body 61; one end of the gun body 61 is connected to a nozzle 62; the nozzle 62 is connected to a grease injection pipe; a first piston 63 and a second piston 64 are arranged parallel inside the gun body 61, wherein grease is stored between the first piston 63 and the nozzle 62; a spring 65 is provided between the first piston 63 and the second piston 64. Under normal circumstances, the spring 65 is kept in a compressed state. When the bearing seat 321 seal fails, the pressure on the spring 65 decreases, and the spring 65 pushes the grease in the gun body 61 into the grease injection pipe, and then into the bearing seat 321; a screw 66 is fixed on the side of the second piston 64 away from the nozzle 62; the screw 66 extends outward through the gun body 61; the screw 66... 6 is threaded to the gun body 61. The gun body 61 can be internally threaded to connect with the screw 66, or a fixed nut can be threaded to the screw 66 inside or outside the gun body 61. The gun body 61 is equipped with an observation window 67, which is made of transparent material. When maintenance personnel conduct regular inspections, if they observe that the first piston 63 in the observation window 67 has moved and deviated from its original position, it indicates that the bearing seat 321 has failed to seal. The maintenance personnel rotate the screw 66, causing the screw 66 to move into the gun body 61. The screw 66 controls the second piston 64 to rotate and move, causing the spring 65 to be compressed again, increasing the time for the oil gun to automatically inject oil into the bearing seat 321, and preventing high-viscosity materials from entering the bearing seat 321 before the separation device stops.

[0051] Example 6

[0052] like Figure 6 As shown, a high-viscosity material separation device, namely a gas-water separation device, includes a cylinder 1 and an anti-clogging device. The cylinder 1 is used to separate and discharge a portion of the water and tar in the gas-water mixture, while the dust-laden tar and tar residue settle into a cone 2. The cylinder 1 is installed at the top of the cone 2. A conical baffle 11 is provided inside the cylinder 1 to isolate tar and water. The gas-water mixture is introduced into the gas-water inlet 12 and then into the central pipe 13. The central pipe 13 passes through the conical baffle 11. The gas-water mixture enters the cylinder 1 at the bottom of the conical baffle 11. Since water has the lowest density in the gas-water mixture, water will rise from the gap between the conical baffle 11 and the cylinder 1 to above the conical baffle 11. When the liquid level reaches a certain height, the water overflows. The gas enters the overflow tank 14 and is discharged through the gas-water outlet 15. The tar in the gas-water is discharged through the tar hopper 16, and the dust-containing tar and tar residue settle. The conical baffle 11 is provided with a connecting hole. The connecting hole is connected to a balance pipe 111. The end of the balance pipe 111 away from the conical baffle 11 extends obliquely upward and is connected to the outer side of the cylinder 1. Since the gas-water contains gas, when there is a large amount of gas and tar in the gas-water, it will cause the pressure at the bottom of the conical baffle 11 to be too high. The gas can be discharged through the balance pipe 111, and some tar can also enter the balance pipe 111. When the tar is discharged from the tar hopper 16, the tar in the balance pipe 111 drops. Other features are the same as in Embodiment 1.

[0053] Example 6 Usage: Gas water is introduced into cylinder 1 through gas water inlet 11. Part of the water and tar in the gas water are separated and discharged in cylinder 1. Dust-laden tar and tar residue settle into cone 2. The drive mechanism is started, which drives the stirring shaft 32 to rotate. The stirring shaft 32 drives the main shaft 21 to rotate, and the tray 33 rotates accordingly. The main shaft 21 drives the rotating frame 22 to rotate. The scraper 23 on the rotating frame 22 scrapes off the dust-laden tar and tar residue adhering to the inner wall of cone 2 and drops it into shell 31. The stirring frame 35 stirs the dust-laden tar and tar residue in shell 31, causing the dust-laden tar and tar residue to flow and be discharged from outlet 312.
