Description

Technical Field

[0001] This invention relates to the field of tubular chain conveying technology, and in particular to a high-performance tubular chain conveyor. Background Technology

[0002] As a highly efficient continuous conveying device, tubular chain conveyors are widely used in industrial fields such as chemical, building materials, and food processing, mainly for conveying bulk materials such as powders and granules. Its core structure typically includes a conveying channel, a conveying section, a drive section, a feeding section, and a discharging section. The working principle is that the drive section provides power, driving the conveying section (such as a traction chain or conveyor plate) to slide in a closed conveying channel, thereby conveying the material input from the feeding section to the discharging section, achieving continuous material transfer.

[0003] In practical applications of existing tubular chain conveyors, the air is not always dry, which can cause powdery materials to absorb moisture and agglomerate. The material being conveyed is placed in the feed hopper and fed into the conveying pipeline under gravity. If the material contains agglomerated material, some of it may become stuck in the feed inlet. When material is stuck in the feed inlet, two situations may occur:

[0004] When the feed inlet is completely blocked by caking material: At this time, the material will continue to accumulate in the feed hopper while there is no material in the conveying pipe. The staff can visually detect this and clear the blockage in time.

[0005] Material did not completely block the feed inlet. Because the caking material did not completely block the feed inlet, the remaining material could enter through the gap between the caking material and the feed inlet. Since the blockage was only partial, material was still being conveyed in the conveying pipe, and the material level in the feed hopper was visibly decreasing. Therefore, it was difficult for operators to detect in time. Some material failed to enter the conveying channel of the tubular chain conveyor in time, causing the material to not enter the conveying pipeline according to the predetermined flow rate. Although the tubular chain conveyor was still running and attempting to convey material, the actual amount of material conveyed was greatly reduced due to the blockage, failing to reach the system's maximum conveying capacity and thus reducing the system's efficiency.

[0006] Because the internal traction disc of the tubular chain conveyor will slide in the conveying pipeline during operation, it will generate slight vibration. Some of the blockage and caking material will usually adjust its posture over time and with the friction between subsequent materials as they pass through, eventually entering the conveying pipeline. This makes it difficult to detect blockages unless the conveying status of the tubular chain conveyor is constantly observed and compared. Even if a blockage is detected, it will be ignored because normal conveying is restored later. However, the conveying efficiency is greatly reduced during the blockage process, and even if it is cleared, the overall conveying efficiency will be reduced, resulting in unnecessary waste of resources. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-performance tubular chain conveyor.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a high-performance tubular chain conveyor, comprising a conveying channel, a conveying unit, and a driving unit. The conveying channel has a closed annular structure, the driving unit is located at the middle position of the annular conveying channel, the conveying unit is slidably disposed inside the conveying channel, and the driving unit can drive the conveying unit to slide along the inside of the conveying channel to convey the powdered material input from the feed unit along the conveying channel, and the powdered material inside the conveying channel can be discharged from the discharge unit.

[0009] Preferably, the conveying channel includes multiple conveying pipes, which are detachably assembled via flanges to form a closed tubular loop. The conveying unit includes multiple conveying plates and a traction component. The multiple conveying plates are connected end-to-end via the traction component to form a closed loop structure. Each conveying plate has an edge fitted with a rubber ring, the edge of which is arc-shaped. The conveying plate slides against the inner wall of the conveying pipe through the rubber ring. The driving unit includes a power component and a traction disc. The power component is fixed to the ground by a bracket. The conveying pipe is fitted onto the surface of the traction disc, and an opening groove is formed at a corresponding position. A locking mechanism is formed on the surface of the traction disc. The traction disc passes through the opening slot and is engaged in the chuck slot. The power component drives the traction disc to rotate through the gearbox, thereby causing the traction component and the connected conveying plate to slide along the conveying pipeline. A discharge port is opened at a position opposite to the bottom of the surface of the conveying pipeline. The discharge part is a discharge hopper and is installed at the discharge port. The powdery material conveyed by the conveying plate can fall into the discharge hopper through the discharge port. The traction component is a steel cable or iron chain. An inclined guide plate is fixedly installed inside the feed hopper of the feed part. The powdery material in the feed hopper can be collected along the guide plate to the feed port.

[0010] Preferably, the feeding section includes the feeding hopper and the supporting leg. The feeding hopper is fixed to the ground by the supporting leg. The bottom of the feeding hopper has the feeding port, which is connected to the conveying pipeline. The feeding hopper and the conveying pipeline are detachably assembled by bolts. The feeding port has a dispersing part inside, which includes a rotating component. When the traction member pulls the conveying plate to slide along the conveying pipeline, the conveying plate can push the rotating component, causing the rotating component to swing inside the feeding hopper to avoid the powdery material from caking and clogging.

[0011] Preferably, the rotating component includes a swing shaft, a swing arm, a breaker sickle, and a saw blade. The swing shaft is rotatably installed inside the feed inlet. The swing arm is fixedly connected to the surface of the swing shaft. When the conveyor plate slides, it can push the swing arm, causing the swing arm to rotate around the swing shaft. The breaker sickle is fixedly connected to the upper end of the swing arm. The end of the breaker sickle is sharp. When the swing arm rotates, it can drive the breaker sickle to scoop up powdery materials inside the feed hopper to break up agglomerated materials. The saw blade is fixedly connected to the surface of the breaker sickle near the end, and the saw blade is twisted to enhance the pulling effect of the breaker sickle on agglomerated materials.

[0012] Preferably, a vibration component is installed at the port of the swing shaft. When the swing shaft rotates, it can drive the vibration component to vibrate, thereby preventing the powdered material from clumping.

[0013] Preferably, the vibration component includes a mounting groove, a gear, a guide rail, a slider, a spring, a counterweight, a rack, and a reset component. The mounting groove is located at the position of the feed hopper relative to the feed inlet. The gear has a half-tooth structure and is rotatably mounted inside the mounting groove. The gear is driven by the swing shaft. The guide rail is fixed inside the mounting groove. The slider is slidably connected to the surface of the guide rail. One end of the spring is fixedly connected to the slider, and the other end is fixedly connected to the counterweight. The rack is fixedly connected to the slider, and the rack meshes with the gear. When the swing shaft rotates, it drives the gear to rotate, thereby driving the rack to slide along the guide rail. The counterweight swings through the spring under inertia. During the swing, the counterweight hits the sealing component at the port of the mounting groove, causing the feed hopper to vibrate. The reset component is located between the rack and the mounting groove. When the rack disengages from the toothless part of the gear, the reset component can drive the rack to quickly reset upward.

[0014] Preferably, the reset component includes a telescopic rod and a reset spring. One end of the telescopic rod is fixedly connected to the inner wall of the mounting groove, and the other end is fixedly connected to the rack. The reset spring is sleeved on the surface of the telescopic rod, and both ends of the reset spring are fixedly connected to the rack and the inner wall of the mounting groove, respectively.

[0015] Preferably, the sealing component includes a sealing plate and a vibrating drum. The sealing plate is assembled and connected to the feed hopper by bolts, and the sealing plate covers the port of the mounting groove. The vibrating drum is installed on the sealing plate at the position corresponding to the counterweight. When the counterweight swings, it can strike the vibrating drum to enhance the vibration effect.

[0016] Preferably, a spring is fixedly connected to the bottom end of the swing arm, and a drive rod is fixedly connected to the bottom end of the spring. The drive rod extends into the conveying channel along the feed inlet. When the traction member pulls the conveying plate to slide, the conveying plate can push the drive rod, thereby driving the swing arm to rotate around the swing axis through the spring. The spring is a spring.

[0017] Preferably, an assembly groove is provided inside the conveying pipeline at a position relative to the flange. A transition ring is fitted inside the assembly groove. The transition ring is inclined along the movement direction of the conveying plate, with the lowest end of the transition ring located inside the assembly groove and the highest end extending beyond the assembly groove. The transition ring is a flexible structure, and the conveying plate can slide along the inclined surface of the transition ring. An assembly ring is fixedly connected to the surface of the transition ring. The assembly ring is clamped between two adjacent flanges and clamped and fixed by the assembly bolts between the two flanges.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0019] 1. In this invention, by setting a dispersing part at the feed inlet, the conveyor plate drives the swing arm to swing the crushing sickle. The sharp crushing sickle end can directly scoop up the lumpy material. The twisted saw blade further enhances the pulling and cutting effect on the lumpy material, which can quickly break up the lumpy material. The whole thing moves with the traction disc during the conveying process without the need for additional power, which can fundamentally eliminate the problem of material blockage.

[0020] 2. In this invention, the swing shaft drives the vibration component to move, and the half-tooth gear and rack work together to drive the counterweight to strike the vibrating drum, so that the feed hopper will vibrate continuously, avoiding material clumping and adhesion. This dual function solves the industry pain point that powdery materials are prone to blockage at the feed inlet and in the early stage of conveying, ensuring uninterrupted conveying and improving work efficiency.

[0021] 3. In this invention, the conveying channel adopts multiple sections of conveying pipelines assembled by flanges to form a closed tubular loop. A flexible transition ring is set inside the pipeline corresponding to the flange position, and the transition ring is arranged at an inclination along the movement direction of the conveying plate. This not only ensures the smoothness of the conveying path, but also adapts to the sliding trajectory of the conveying plate, effectively preventing the conveying plate from getting stuck at the pipeline connection, and reducing the residue of materials at the pipeline connection.

[0022] 4. In this invention, the wear-resistant rubber ring on the edge of the conveying plate fits tightly against the inner wall of the pipeline, so that the force is uniform when pushing the material, which further improves the stability of the conveying and the material conveying rate, and reduces material waste.

[0035] Example 1, such as Figure 1-11As shown, a high-performance tubular chain conveyor includes a conveying channel 2, a conveying section 5, and a drive section 1. The conveying channel 2 has a closed annular structure. The drive section 1 is located in the middle of the annular conveying channel 2. The conveying section 5 is slidably disposed inside the conveying channel 2. The drive section 1 can drive the conveying section 5 to slide along the inside of the conveying channel 2 to convey the powdered material input from the feed section 3 along the conveying channel 2. The powdered material inside the conveying channel 2 can be discharged from the discharge section 4. The conveying channel 2 includes multiple conveying pipes 21, which are detachably assembled via flanges to form a closed tubular loop. Corresponding through holes are provided on the flanges, and bolts pass through these holes to fix adjacent conveying pipes 21. Sealing gaskets are installed at the connections to ensure the airtightness of the conveying process. The conveying unit 5 includes multiple conveying plates 51 and traction components 52. The multiple conveying plates 51 are connected end-to-end via the traction components 52 to form a closed loop structure. The traction components 52 are steel cables or chains, and their ends are fixed by connector buckles. Rubber rings are fitted around the edges of the conveying plates 51. These rubber rings are made of wear-resistant rubber and are press-fitted into the grooves on the edges of the conveying plates 51. The edges of the rubber rings are arc-shaped, allowing the conveying plates 51 to slide against the inner wall of the conveying pipes 21 via the rubber rings. The driving unit 1 includes a power component 11 and a traction disc 12. The power component 11 is a drive motor, connected to the input end of a gearbox via a coupling. The output end of the gearbox is fixed to the shaft of the traction disc 12. The power component 11 is fixed by a bracket. The support frame is made of welded steel structure and fixed to the ground with expansion bolts at the bottom. The conveying pipe 21 is fitted onto the surface of the traction disc 12 and has an opening groove at the corresponding position. The edge of the opening groove is chamfered. The surface of the traction disc 12 has a chuck groove. The shape of the chuck groove is adapted to the traction component 52. The traction disc 12 passes through the opening groove and is locked in the chuck groove. The power component 11 drives the traction disc 12 to rotate through the gearbox, thereby driving the traction component 52 and the connected conveying plate 51 to slide along the conveying pipe 21. The surface of the conveying pipe 21 has an outlet at the lower position. The outlet part 4 is a discharge hopper. The outlet part 4 is bolted to the outlet. The powdery material conveyed by the conveying plate 51 can fall into the discharge hopper through the outlet. The feed hopper 31 of the feed part 3 has an inclined guide plate 34 fixedly installed inside. The surface of the guide plate is smoothed. Both ends are fixed to the inner wall of the feed hopper 31 with bolts. The powdery material in the feed hopper 31 can be collected along the guide plate 34 to the feed inlet 32.The feeding section 3 includes a feeding hopper 31 and support legs 33. The support legs 33 are evenly distributed around the bottom of the feeding hopper 31 and are welded and fixed to the bottom of the feeding hopper 31. Anti-slip pads are provided at the bottom of the support legs 33. The feeding hopper 31 is fixed to the ground by the support legs 33. The bottom of the feeding hopper 31 has a feeding port 32, which is connected to the conveying pipeline 21. The feeding hopper 31 and the conveying pipeline 21 are detachably assembled by bolts. A sealing gasket is provided at the connection to prevent dust leakage. A dispersion section 6 is provided inside the feeding port 32. The dispersion section 6 includes a rotating component 61. When the traction component 52 pulls the conveying plate 51 to slide along the conveying pipeline 21, the conveying plate 51 can push the rotating component 61, causing the rotating component 61 to swing inside the feeding hopper 31 to avoid the powdery material from caking and clogging. The rotating component 61 includes a swing shaft 611, a swing arm 612, a breaker 615, and a saw blade 616. The swing shaft 611 is rotatably mounted inside the feed inlet 32 ​​via a bearing. The bearing is a sealed bearing to prevent dust from entering and affecting the rotational flexibility. The swing arm 612 is fixed to the surface of the swing shaft 611 via a key connection. The keyway fits tightly to ensure that the swing arm 612 can rotate synchronously with the swing shaft 611. When the conveyor plate 51 slides, it can push the swing arm 612, causing the swing arm 612 to rotate around the swing shaft 611. The breaker 615 is welded and fixed to the upper end of the swing arm 612. The end of the breaker 615 is sharp and is hardened to improve its hardness. When the swing arm 612 rotates, it can drive the breaker 615 to scoop up powdery materials inside the feed hopper 31 to break up agglomerated materials. The saw blade 616 is welded and fixed to the surface of the breaker 615 near the end. The saw blade 616 is twisted to enhance the pulling effect of the breaker 615 on agglomerated materials. A vibration component 62 is installed at the port of the swing shaft 611. When the swing shaft 611 rotates, it can drive the vibration component 62 to vibrate, thereby preventing the powdery material from clumping.Vibration component 62 includes a mounting groove, a gear 626, a guide rail 621, a slider 622, a spring bar 623, a counterweight 624, a rack 625, and a reset component 627. The mounting groove is located in the feed hopper 31 relative to the feed inlet 32. The gear 626 is a semi-tooth structure and is rotatably mounted inside the mounting groove via a flat key. The gear 626 is connected to the swing shaft 611 for transmission. The guide rail 621 is a rectangular guide rail and is fixed inside the mounting groove by bolts. The slider 622 is slidably connected to the surface of the guide rail 621. The sliding mating surfaces of the slider 622 and the guide rail 621 are coated with grease. One end of the spring bar 623 is welded to the slider 622, and the other end is welded to the counterweight 624. 623 is made of elastic steel sheet, and the counterweight 624 is a cylindrical iron block with rust-proof treatment. The rack 625 is welded and fixed to the slider 622. The rack 625 meshes with the gear 626. When the swing shaft 611 rotates, it drives the gear 626 to rotate, which in turn drives the rack 625 to slide along the guide rail 621. Under the action of inertia, the counterweight 624 swings through the elastic bar 623. During the swing, the counterweight 624 hits the sealing member 63 at the port of the mounting slot, causing the feed hopper 31 to vibrate. The reset member 627 is set between the rack 625 and the mounting slot. When the rack 625 disengages from the toothless part of the gear 626, the reset member 627 can drive the rack 625 to quickly reset upward. The reset component 627 includes a telescopic rod and a reset spring. One end of the telescopic rod is welded and fixed to the inner wall of the mounting groove, and the other end is welded and fixed to the rack 625. The telescopic rod has a multi-stage telescopic structure. The reset spring is sleeved on the surface of the telescopic rod, and both ends of the reset spring are welded and fixed to the rack 625 and the inner wall of the mounting groove, respectively. The reset spring is a compression spring with sufficient elastic restoring force. The blocking component 63 includes a blocking plate 631 and a vibrating drum 632. The blocking plate 631 is made of steel plate and is assembled and connected to the feed hopper 31 by bolts. The blocking plate 631 covers the port of the mounting groove. The vibrating drum 632 is made of elastic material and is installed on the blocking plate 631 at the position corresponding to the counterweight 624. When the counterweight 624 swings, it can strike the vibrating drum 632 to enhance the vibration effect. A spring element 613 is welded and fixed to the bottom end of the swing arm 612. A drive rod 614 is welded and fixed to the bottom end of the spring element 613. The spring element 613 is a spring. The drive rod 614 extends into the conveying channel 2 along the feed inlet 32. One end of the drive rod 614 that extends into the conveying channel 2 is provided with a rounded corner. When the traction member 52 pulls the conveying plate 51 to slide, the conveying plate 51 can push the drive rod 614, which in turn drives the swing arm 612 to rotate around the swing axis 611 through the spring element 613.An assembly groove 22 is provided inside the conveying pipeline 21 at a position relative to the flange. The assembly groove 22 is an annular groove, and a transition ring 23 is fitted inside the assembly groove 22. The transition ring 23 is made of silicone material, which has good flexibility and wear resistance. The transition ring 23 is inclined along the movement direction of the conveying plate 51. The lowest end of the transition ring 23 is located inside the assembly groove 22, and the highest end extends beyond the assembly groove 22. The conveying plate 51 can slide along the inclined surface of the transition ring 23. An assembly ring 24 is integrally formed on the surface of the transition ring 23. The assembly ring 24 is clamped between two adjacent flanges and is clamped and fixed by the assembly bolts between the two flanges. The assembly ring 24 has holes corresponding to the flange through holes to ensure that the bolts can pass through smoothly.

[0036] Working principle: The power component 11 of the drive unit 1 is activated. The power component 11 is a drive motor. The output shaft of the motor is fixedly connected to the input end of the gearbox via a coupling. The output end of the gearbox is rigidly connected to the rotating shaft of the traction disc 12. Through the speed regulation function of the gearbox, the output speed of the motor can be converted into the rotation speed required by the traction disc 12, ensuring smooth and efficient power transmission. The surface of the traction disc 12 is provided with a chuck groove that matches the traction component 52. The conveying pipe 21 is fitted onto the surface of the traction disc 12 and has an opening groove at the corresponding position. After the traction disc 12 passes through the opening groove, its chuck groove is tightly engaged with the traction component 52, which forms a closed ring structure by connecting the two ends. When the traction disc 12 rotates under the drive of the motor and the gearbox, it will generate a circumferential pulling force on the traction component 52 through the chuck groove, thereby driving the traction component 52 and the multiple conveying plates 51 connected in series on the traction component 52 to perform a cyclic sliding motion along the annular conveying channel 2 formed by assembling multiple sections of conveying pipe 21. After the powdered material is filled into the feed hopper 31 of the feed section 3, the material slides and gathers along the surface of the guide plate 34 inclined inside the feed hopper 31 under its own gravity. The surface of the guide plate 34 is smoothed to reduce the sliding resistance of the material and ensure that the material gathers smoothly to the feed port 32 at the bottom of the feed hopper 31. When the conveyor plate 51 slides to the feed inlet 32 ​​with the traction member 52, the rubber ring on the edge of the conveyor plate 51 first contacts the end of the drive rod 614 that extends into the conveying channel 2. Since the end of the drive rod 614 that extends into the conveying channel 2 is provided with a rounded corner, it can avoid rigid collision with the rubber ring of the conveyor plate 51. As the conveyor plate 51 continues to slide, it will generate a horizontal thrust on the drive rod 614. The drive rod 614 transmits this thrust to the elastic member 613 connected to its upper end. The elastic member 613 is a spring, which undergoes elastic deformation under the action of the thrust, thereby driving the swing arm 612, which is fixedly connected to the upper end of the elastic member 613, to rotate around the swing shaft 611. The swing shaft 611 is rotatably installed inside the feed inlet 32 ​​through a sealed bearing. The sealed bearing can prevent dust from entering the bearing gap and affecting the rotation flexibility, ensuring that the swing arm 612 stably performs reciprocating swing motion around the swing shaft 611. The breaker 615, which is welded and fixed to the upper end of the swing arm 612, swings synchronously with the swing arm 612. The end of the breaker 615 is sharpened by quenching. During the swing, it can penetrate into the material pile in the feed hopper 31 to scoop and cut the agglomerated or caking material. At the same time, the twisted saw blade 616 on the surface of the breaker 615 near the end will pull and tear the agglomerated material, decomposing large pieces of caking material into small particles and preventing the agglomerated material from blocking the feed inlet 32.While the swing shaft 611 rotates, the half-tooth gear 626 fixedly connected to its port rotates synchronously. When the toothed part of the gear 626 meshes with the rack 625, it drives the rack 625 to slide downward along the guide rail 621 fixed in the mounting groove. The rack 625 is fixedly connected to the slider 622. When the slider 622 slides along the guide rail 621, the grease applied to its surface reduces the sliding friction resistance. The slider 622 drives the spring 623 fixed at one end to move downward synchronously. The spring 623 is made of elastic steel sheet and accumulates elastic potential energy during the downward movement. At the same time, the counterweight 624 connected to the other end of the spring 623 moves downward under the action of inertia. When the toothless part of the gear 626 rotates to the position opposite to the rack 625, the rack 625 loses the driving force of the gear 626. At this time, the rack 625 and the mounting groove are... The reset component 627 begins to function, and the reset spring of the reset component 627 releases elastic potential energy, pushing the rack 625 to quickly reset upward along the guide rail 621. The slider 622 drives the spring bar 623 and the counterweight 624 to move upward synchronously. Under the combined action of inertia and the elastic force of the spring bar 623, the counterweight 624 generates an upward swinging impact force, which hits the vibrating drum 632 on the sealing plate 631 at the mounting slot port. The vibrating drum 632 is made of elastic material and vibrates after being hit. This vibration is transmitted to the entire feed hopper 31 through the sealing plate 631, causing the inner wall of the feed hopper 31 to vibrate continuously, effectively preventing powdery materials from adhering and forming balls on the inner wall of the feed hopper 31. Combined with the mechanical crushing action of the crushing sickle 615, a double anti-blocking mechanism is formed, which completely solves the problem of blockage of powdery materials at the feed inlet 32 ​​and in the initial stage of conveying. After the conveyor plate 51 pushes the drive rod 614 to complete one swing, as the traction component 52 continues to drive the conveyor plate 51 to slide, the conveyor plate 51 disengages from the drive rod 614. Under the action of its own elastic restoring force, the elastic component 613 drives the drive rod 614 and the swing arm 612 to reset, preparing for the next engagement with the conveyor plate 51 that subsequently slides to the feed inlet 32. The powdered material after crushing enters the interior of the conveying channel 2 under the continuous sliding action of the conveyor plate 51. The rubber ring on the edge of the conveyor plate 51 is made of wear-resistant rubber and is interference-fitted with the inner wall of the conveying pipe 21, which can ensure the sealing between the conveyor plate 51 and the inner wall of the pipe and prevent material leakage from the gap. At the same time, the arc-shaped structure of the edge of the rubber ring can reduce the sliding resistance, allowing the conveyor plate 51 to smoothly push the material to slide along the interior of the conveying pipe 21. When the conveyor plate 51 slides past the flange connection of the adjacent conveying pipeline 21, the transition ring 23, which is installed in the assembly groove 22 inside the conveying pipeline 21, plays a role. The transition ring 23 is made of silicone material, which has good flexibility and wear resistance. It is inclined along the movement direction of the conveyor plate 51, with its highest point extending beyond the assembly groove 22 and its lowest point located inside the assembly groove 22. The conveyor plate 51 can slide smoothly along the inclined surface of the transition ring 23, avoiding jamming of the conveyor plate 51 or material residue at the flange connection due to the pipeline connection gap, thus ensuring the continuity and smoothness of the conveying path.When the conveyor plate 51 drives the material to slide to the outlet position opposite to the surface of the conveying pipe 21, the material falls from the outlet into the discharge hopper installed at the outlet under the combined action of its own gravity and the thrust of the conveyor plate 51. After the discharge hopper collects the material, the entire conveying process is completed. Since the entire conveying process is carried out in the closed annular conveying channel 2, the sealing gaskets set at the flange connection of the conveying pipe 21 and the sealing gaskets at the connection between the feed hopper 31 and the conveying pipe 21 can effectively prevent dust from overflowing.
