A screw conveyor for carbon black production

Abstract

This invention belongs to the field of screw conveying technology and discloses a screw conveyor for carbon black production, including a support assembly; two drive assemblies; a feeding assembly; two conveying assemblies; and two rotating assemblies. A third motor drives a fourth gear through a third gear, which in turn drives a gear ring and a triangular rod to rotate the cylindrical shell inside the shell. After several rotations, the third motor is de-energized, and the screw rod continues to rotate due to inertia until it stops. At this time, the stroke of the hydraulic rod is increased, and the third gear disengages from the fourth gear and engages with multiple fixed rods. When the power is restored, the third motor drives the triangular rod to rotate, causing the water inside the cylindrical shell to clean the inner wall of the cylindrical shell and the screw rod under the action of rotation, and then discharges from the second discharge port. This method solves the problems of water stratification and poor cleaning effect during cleaning in traditional screw conveyors.

Description

Technical Field

[0001] The invention belongs to the technical field of screw transportation, in particular to a screw conveyor for carbon black production. Background Art

[0002] The production principle of carbon black is to form carbon black particles by burning or pyrolyzing organic matter or petroleum residues containing carbon elements under limited oxygen supply conditions. The most common furnace production process in industry is to use natural gas or high aromatic oil to produce carbon black by incomplete combustion or pyrolysis in a reactor. When transporting these liquid raw materials, a screw conveyor with a simple structure and closed transportation is used.

[0003] The working principle of the screw conveyor is mainly to rotate the screw rod through the driving device, and push the liquid from one end of the screw rod to the other end in a linear transportation process. After the transportation is completed, the screw conveyor usually needs to be cleaned. The commonly used cleaning method is to pass a large amount of clean water at the feed inlet, and use the impact of the water to flush out the residual materials in the pipe. However, in the process of water flowing in the pipe, laminar flow and partial eddy current will be generated. The laminar water flow is stable and slow, and it is easy to form a flow velocity stratification phenomenon, that is, the water flow in the center of the pipe is faster, and the water flow near the pipe wall is slower, which leads to uneven flushing, and the partial eddy current is not enough to cover the inner wall of the entire pipe, so the cleaning effect of the entire screw conveyor is not good. Summary of the invention

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention is equipped with a newly designed rotating assembly. The third motor drives the fourth gear through the third gear, and then drives the gear ring and the triangular rod to rotate the round shell in the shell. After rotating for several circles, the third motor is powered off, and the spiral rod continues to rotate due to inertia until it stops. At this time, the hydraulic rod stroke is increased, the third gear is disengaged from the fourth gear and clamped on multiple fixed rods.

When it is necessary to stop the operation of the transport component, the power output of the first motor is disconnected first. However, the transport component will rotate a certain angle under the action of inertia. At this time, the travel of the telescopic rod is contracted, and the telescopic rod will drive the two rotating blocks to rotate along the axis of the rotating rod to clamp the rotating blocks. The rotating blocks are subjected to the friction force from the two friction blocks, which will be immediately fed back to the second gear through the first gear, and the inertially rotating spiral rod will immediately stop.

[0017] 3. The present invention is equipped with a feed assembly having a wave roller. The rotation of the second motor drives the double-headed bevel gear to rotate, and then the two bevel gears meshing with the double-headed bevel gear can drive the two wave rollers to rotate symmetrically in the square shell. The circular holes on the wave roller impeller can have a disturbing effect on the liquid. Under the rotation of the wave-shaped impeller, the liquid flows at a uniform speed in the square shell toward the first feed port. The symmetrical rotation of the two wave rollers provides a uniform power distribution, so that the flow of the liquid in the square shell is more balanced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 11 As shown, an embodiment of the present invention provides a screw conveyor for carbon black production, including a support assembly 1, two drive assemblies 2 are fixedly installed on the left side of the support assembly 1, and also includes a linked screw transport mechanism, which includes a feed assembly 3, the feed assembly 3 is fixedly installed on the right side of the two drive assemblies 2, and two transport assemblies 4 are fixedly installed on the right side of the feed assembly 3;

[0032] Two rotating components 5, the two rotating components 5 are fixedly installed on the right side of the two transport components 4, the rotating components 5 include a third motor 51, the output shaft of the third motor 51 is fixedly connected to a hydraulic rod 52, the telescopic end of the hydraulic rod 52 is fixedly connected to a third gear 53, the left and right sides of the third gear 53 are meshed with fourth gears 54, the front ends of the two fourth gears 54 are fixedly connected to a bent rod 55, the outer edges of the two fourth gears 54 are meshed with a gear ring 56, the back of the gear ring 56 is fixedly installed with a triangular rod 57, and the front end of the triangular rod 57 is fixedly installed with multiple fixed rods 58; the third gear 53 can be disengaged from the two fourth gears 54 under the elongation of the hydraulic rod 52, and move to the triangular rod 57 to be movably engaged with the multiple fixed rods 58;

[0033] The third motor 51 drives the third gear 53 to rotate clockwise through the hydraulic rod 52, and the fourth gear 54 meshing on both sides of the third gear 53 will drive the gear ring 56 to rotate counterclockwise, and the round shell 41 will be driven to rotate clockwise in the housing 13 through the triangular rod 57. After rotating for several circles, the third motor 51 is powered off, and the spiral rod 44 will slowly rotate until it stops under the action of inertia. At this time, the stroke of the hydraulic rod 52 is increased again. At this time, the third gear 53 will release the meshing with the fourth gears 54 on both sides, and move to the triangular rod 57, and be movably connected with the multiple fixed rods 58. Then the third motor 51 is powered on to drive clockwise, which will drive the triangular rod 57 to rotate clockwise. The water flow in the round shell 41 will clean the inner wall of the round shell 41 and the spiral rod 44 under counterclockwise and clockwise rotation, and be discharged from the second discharge port 43 through the housing 13;

[0034] In this stage, the third motor 51 always rotates clockwise, which greatly reduces the electrical wear caused by the motor first rotating clockwise and then counterclockwise, and the winding of the motor is subjected to a large electromagnetic force in the repeatedly changing current, which leads to the gradual aging of the insulation material of the winding. It also reduces the impact force on the bearing of the motor when changing the rotation direction, which significantly shortens the service life of the bearing and causes mechanical wear of premature damage to the bearing. The load equipment driven by the motor will be subjected to the instantaneous torque changes of reciprocating starting and reversing. This continuous reverse torque impact will cause metal material fatigue problems.

[0035] The support assembly 1 includes a plurality of support rods 11, a fixing bar 12 is fixedly installed on the top of the two left support rods 11, a housing 13 is fixedly connected to the right side of the fixing bar 12, two first discharge ports 14 are provided at the bottom of the housing 13, a fixing plate 15 is fixedly connected to the right side of the housing 13, and the top of the fixing plate 15 is fixedly connected to the third motor 51 and the two bent rods 55;

[0036] The arrangement of multiple support rods 11 can effectively improve the stability of the entire device, making it more stable during operation and less prone to tilting or shaking. The two first discharge ports 14 opened at the bottom of the shell 13 can discharge materials at the same time, greatly improving the efficiency of discharging materials.

[0037] The driving assembly 2 includes a first motor 21, which is fixedly mounted on the top of the fixing bar 12.

A rotating rod 25 is movably hinged at the middle position of the left side of the two friction blocks 24, and a telescopic rod 26 is movably hinged at the back of the two friction blocks 24; the rotating rod 25 and the telescopic rod 26 are both fixedly connected to the left end of the housing 13, and the two friction blocks 24 can clamp the rotating block 23 under the action of the telescopic rod 26;

[0038] The first motor 21 drives the first gear 22 to rotate, and the second gear 27 meshing with the first gear 22 drives the screw rod 44 to rotate, and the liquid entering from the second feed port 42 is spirally transported to the right end of the round shell 41, and discharged from the second discharge port 43 through the first discharge port 14. When it is necessary to stop the operation of the transport component 4, the power output of the first motor 21 is disconnected first, but the transport component 4 will rotate a certain angle under the action of inertia, and the travel of the telescopic rod 26 will be contracted at this time. The telescopic rod 26 will drive the two rotating blocks 23 to rotate along the axis of the rotating rod 25 to clamp the rotating block 23. The rotating block 23 is subjected to the friction force from the two friction blocks 24, and will be immediately fed back to the second gear 27 through the first gear 22, and the inertial rotating screw rod 44 will be stopped immediately;

[0039] The feed assembly 3 includes a square shell 31, which is fixedly mounted on the top left side of the housing 13. Two first feed ports 32 are provided at the bottom of the square shell 31. Two wave rollers 33 are rotatably mounted in the square shell 31. The impellers of the two wave rollers 33 are provided with a plurality of circular holes 34. The right sides of the two wave rollers 33 are fixedly connected with bevel gears 35. The right sides of the two bevel gears 35 are meshed with double-headed bevel gears 36. The rotating shaft of the double-headed bevel gear 36 is fixedly connected with a second motor 37. The second motor 37 is fixedly connected to the outer wall of the square shell 31.

[0040] First, the second motor 37 is started, and the rotation of the second motor 37 drives the double-headed bevel gear 36 to rotate, and then the two bevel gears 35 meshing with the double-headed bevel gear 36 can drive the two wave rollers 33 to rotate symmetrically in the square shell 31. The circular holes 34 opened on the impeller of the wave roller 33 can have a disturbing effect on the liquid. Under the rotation of the wave-shaped impeller, the liquid flows at a uniform speed in the square shell 31 toward the first feed port 32;

[0041] The transport assembly 4 includes a round shell 41, which is movably mounted in the housing 13. A second feed port 42 is provided at the top left side of the round shell 41, and a second discharge port 43 is provided at the bottom right side of the round shell 41. A screw rod 44 is rotatably mounted inside the round shell 41. The second feed port 42 fits with the first feed port 32, and the second discharge port 43 fits with the first discharge port 14. The left end of the rotating shaft of the screw rod 44 is fixedly connected to the second gear 27, and the right end of the rotating shaft of the screw rod 44 is fixedly connected to the triangular rod 57.

[0042] When feeding, the second gear 27 will drive the screw rod 44 to rotate, and the liquid entering from the second feed port 42 will be spirally transported to the right end of the round shell 41, and discharged from the second discharge port 43 through the first discharge port 14. When cleaning, the triangular rod 57 will drive the round shell 41 to rotate clockwise and counterclockwise in the shell 13. The water flow in the round shell 41 will clean the inner wall of the round shell 41 and the screw rod 44 while rotating counterclockwise and clockwise, and be discharged from the second discharge port 43 through the shell 13.

[0043] Working principle:

[0044] When the screw conveyor is used to transport carbon black raw materials, the liquid raw materials are first fed into the feed assembly 3, and the second motor 37 is first started. The rotation of the second motor 37 drives the double-headed bevel gear 36 to rotate, and then the two bevel gears 35 meshing with the double-headed bevel gear 36 can drive the two wave rollers 33 to rotate symmetrically in the square shell 31. The circular holes 34 opened on the impeller of the wave roller 33 can have a disturbing effect on the liquid. Under the rotation of the wave-shaped impeller, the liquid flows at a uniform speed in the square shell 31 toward the first feed port 32;

[0045] When the liquid enters the round shell 41 from the first feed port 32 through the second feed port 42, the driving component 2 is started, the first motor 21 drives the first gear 22 to rotate, and the second gear 27 meshing with the first gear 22 drives the screw rod 44 to rotate, and the liquid entering from the second feed port 42 is spirally transported to the right end of the round shell 41, and discharged from the second discharge port 43 through the first discharge port 14. When it is necessary to stop the operation of the transport component 4, the power output of the first motor 21 is disconnected first, but the transport component 4 will rotate a certain angle under the action of inertia, and the travel of the telescopic rod 26 will be retracted at this time. The telescopic rod 26 will drive the two rotating blocks 23 to rotate along the axis of the rotating rod 25 to clamp the rotating block 23. The rotating block 23 is subjected to the friction force from the two friction blocks 24, and will be immediately fed back to the second gear 27 through the first gear 22, and the inertial rotating screw rod 44 will immediately stop rotating;

[0046] When the conveying is completed and cleaning is required, first, clean water is injected from the feeding assembly 3, and the clean water will enter the round shell 41 after passing through the first feeding port 32 and the second feeding port 42. At this time, the rotating assembly 5 is started again, and the third motor 51 drives the third gear 53 to rotate clockwise through the hydraulic rod 52, and the fourth gear 54 meshing on both sides of the third gear 53 will drive the gear ring 56 to rotate counterclockwise, and the round shell 41 will be driven to rotate clockwise in the shell 13 through the triangular rod 57. After rotating for several circles, the third motor 51 is powered off, and the spiral rod 44 will rotate in the shell 13. It rotates slowly under the action of inertia until it stops. At this time, the stroke of the hydraulic rod 52 is increased. At this time, the third gear 53 will release the engagement with the fourth gears 54 on both sides, and move to the triangular rod 57, and movably engage with multiple fixed rods 58. Then the third motor 51 is energized and driven clockwise, which will drive the triangular rod 57 to rotate clockwise. The water flow in the circular shell 41 will clean the inner wall of the circular shell 41 and the spiral rod 44 while rotating counterclockwise and clockwise, and will be discharged from the second discharge port 43 through the shell 13. The working process ends here.
