Description

Technical Field

[0001] This utility model relates to the field of pneumatic conveying equipment technology, and in particular to a novel pneumatic conveying ship loading system. Background Technology

[0002] Pneumatic conveying technology, as an efficient and clean method for transporting bulk materials, has been widely used in ship loading operations at port terminals, especially suitable for the rapid loading of granular materials such as cement, grain, and fly ash. During the loading process, the end of the conveying system is usually connected to the ship's receiving hatch using wear-resistant flexible hoses to accommodate the ship's swaying and positional changes.

[0003] However, as a wear-resistant component, the abrasion-resistant hose needs frequent replacement due to wear or damage during use. Under current technological conditions, replacing the hose usually requires stopping the entire delivery system and then manually disassembling the connecting flange or clamps.

[0004] During this dismantling process, the lack of an effective quick-sealing device for the ports leaves the pipeline ports instantly exposed to the atmosphere. This not only leads to leakage of residual material inside the pipeline, causing economic losses and environmental pollution, but also allows moisture, dust, and other impurities in the air to easily enter the pipeline system, affecting the purity of subsequently transported materials. Furthermore, the manual dismantling and installation process is cumbersome and time-consuming, significantly reducing the continuity and overall efficiency of the loading operation.

[0005] Therefore, this utility model proposes a novel pneumatic conveying and loading system to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a novel pneumatic conveying and loading system, which aims to improve the problem that some pneumatic conveying pipelines in the prior art lack effective and quick sealing devices at the pipeline ports during replacement or maintenance, leading to material leakage and the entry of external impurities, while the replacement process is complicated and time-consuming.

[0007] This utility model provides a novel pneumatic conveying and loading system for ships, including a movable loading device, a powder conveying pipe on the movable loading device, a widened port at one end of the powder conveying pipe, and a hose connector that can be detachably connected to the widened port.

[0008] The new pneumatic conveying and loading system also includes a self-sealing quick-connect mechanism and sealing components for the pipes located at the widened opening.

[0009] The self-sealing quick-connect mechanism for pipes includes a self-sealing outer ring fixedly connected to the outer periphery of the widened opening, a sleeve fitted over the outer ring, a locking housing fixedly connected to the outer periphery of the sleeve, and a locking cylinder rotatably connected inside the locking housing. The locking cylinder has a groove, and the hose connector also has a groove on its outer periphery. When the locking cylinder is rotated until its groove aligns with the outer edge of the self-sealing outer ring, the hose connector can be pulled out of the widened opening. When the hose connector is inserted, rotating the locking cylinder causes its solid part to engage with the groove of the hose connector, achieving a locking and securing effect.

[0010] The sealing assembly is located inside the self-sealing outer ring and includes a fixed block fixedly disposed inside the self-sealing outer ring, a sliding post slidably connected inside the fixed block, and a sealing plug fixedly connected to one end of the sliding post. The sealing assembly also includes a spring sleeved on the sliding post, with its two ends respectively abutting against the fixed block and the sealing plug. A fixed rod is fixedly connected inside the hose connector, one end of the fixed rod is connected to a connecting rod, and the other end of the connecting rod is connected to a top cone.

[0011] When the hose connector is inserted into the widened port, the top cone pushes the sealing plug to compress the spring, connecting the powder conveying pipe to the hose connector. When the hose connector is pulled out of the widened port, the top cone disengages from the widened port, and the spring pushes the sealing plug to fit against the self-sealing outer ring, forming a self-sealing seal. Through the ingenious combination of the pipeline self-sealing quick-connect mechanism and the sealing component, automatic sealing is achieved during pipeline connection and separation, effectively preventing material leakage and impurity entry.

[0012] Preferably, the system also includes a floor and a temporary storage bin. The temporary storage bin is fixedly installed on top of the floor, while the movable loading device is installed on the floor and can move along the top of the floor. A hose connector connects to one end of a wear-resistant hose, providing a stable base platform and material storage space for the operation of the entire system.

[0013] Preferably, the movable loading device is also equipped with a height adjustment mechanism. This mechanism adjusts the height of the wear-resistant hose to accommodate different loading requirements. The height adjustment mechanism includes a telescopic cylinder and a height extension plate. The height extension plate is connected to the output end of the telescopic cylinder and can be raised and lowered under the cylinder's drive. The mechanism also includes guide wheels located outside the height extension plate. These guide wheels are slidably connected to a groove inside the movable loading device, providing precise guidance for the raising and lowering of the height extension plate and ensuring smooth operation.

[0014] Preferably, the height adjustment mechanism further includes a fixed arm, a rotating column, a fulcrum block, a rubber fixing ring, and a rubber rotating ring. The fixed arm is fixedly connected to the outside of the height extension plate. The rotating column is rotatably connected to the inside of the fixed arm. The fulcrum block is fixedly connected to the outside of the rotating column. A rubber fixing ring is fixedly connected to the fulcrum block, and a rubber rotating ring is rotatably connected to it. The wear-resistant hose is clamped and fixed by the rubber fixing ring and the rubber rotating ring, achieving stable support and flexible installation of the wear-resistant hose.

[0015] Preferably, it also includes a fixing component. The fixing component is disposed on the rubber rotating retaining ring and is used to ensure the safe locking of the wear-resistant hose after height adjustment. The fixing component includes a support block fixedly connected to the outside of the rubber rotating retaining ring, a rotating collar rotatably connected to the support block, and a locking block sleeved by the rotating collar.

[0016] Preferably, a limiting plate and a sliding head are slidably connected inside the locking block. A push spring is also provided inside the locking block to push the sliding head outward. When the rotating collar rotates, the protrusion on its inner wall contacts the sliding head, pushing the sliding head inward and compressing the push spring. Under the elastic force of the push spring, the sliding head can engage inside the limiting plate, forming a safety lock that prevents the locking block from rotating in the opposite direction, significantly improving the safety of equipment operation.

[0017] Preferably, the movable loading device is also equipped with sliding wheels. The installation position of the sliding wheels allows them to roll into contact with the outer wall of the wear-resistant hose, providing support and reducing friction when the wear-resistant hose moves, thereby extending the service life of the wear-resistant hose.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting a self-sealing quick-connect mechanism and sealing components for the pipeline, enables the sealing plug to automatically seal the port of the powder conveying pipe under the action of a spring when the hose connector is pulled out. This solves the problems of complicated operation, easy material leakage and impurity contamination when replacing pneumatic conveying pipelines in the prior art, and achieves the technical effects of quick pipeline replacement, automatic sealing and leak prevention, improved work efficiency and environmental protection.

[0019] 2. This utility model, by setting a height adjustment mechanism and a fixing component with a safety locking function, and using a locking structure formed by a slider, push spring and limit plate, solves the problem of unstable fixing of the conveying hose and the safety hazard of accidental fall in the prior art. It achieves the technical effect of precise adjustment and reliable locking of the hose height, and significantly improves the safety of operation.

[0020] 3. This utility model integrates a movable loading device, a height adjustment mechanism, and a self-sealing quick-connect mechanism into one unit. The structure is compact and reasonable, which solves the problems of single function and poor adaptability of existing loading equipment. It achieves the technical effect of complete system function, flexible operation, and adaptability to different ship loading needs, and has high practical value. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figures 1 to 5 This utility model provides a novel pneumatic conveying and loading system, which aims to solve the problems of material leakage, impurity entry, and complex and time-consuming replacement process when existing pneumatic conveying pipelines are replaced or repaired.

[0025] like Figure 1 and Figure 2 As shown, the novel pneumatic conveying loading system includes a movable loading device 7 and a powder conveying pipe 31 installed on the movable loading device 7. The movable loading device 7 serves as the mobile and operational platform for the entire system, while the powder conveying pipe 31 serves as the main material conveying channel.

[0026] The new pneumatic conveying and loading system is equipped with a self-sealing quick-connect mechanism 3 and a sealing assembly 38. One end of the powder conveying pipe 31 has a widened port 32. A self-sealing outer ring 33 is fixedly connected to the outer periphery of the widened port 32. A sleeve 34 is fitted over the self-sealing outer ring 33. A lock housing 36 is fixedly connected to the outside of the sleeve 34. A locking core 37 is rotatably connected inside the lock housing 36. A hose connector 35 is detachably connected to the widened port 32.

[0027] A sealing assembly 38 is disposed inside the self-sealing outer ring 33. The sealing assembly 38 includes a fixing block 381, a sliding post 382, ​​a spring 383, and a sealing plug 384. The fixing block 381 is fixedly disposed inside the self-sealing outer ring 33. The sliding post 382 is slidably connected to the inside of the fixing block 381. The sealing plug 384 is fixedly connected to one end of the sliding post 382. The spring 383 is sleeved on the sliding post 382, ​​with its two ends abutting against the fixing block 381 and the sealing plug 384 respectively. It is used to push the sealing plug 384 to move in the direction of the widening opening 32, so that the edge of the sealing plug 384 can fit against the inner wall of the self-sealing outer ring 33 under the elastic force of the spring 383 to form a seal.

[0028] A fixing rod 385 is fixedly connected internally to the hose connector 35. One end of the fixing rod 385 is connected to a connecting rod 386. The other end of the connecting rod 386 is connected to a top cone 387.

[0029] When the hose connector 35 needs to be inserted into the widened opening 32, the locking core 37 rotates until its groove aligns with the outer edge of the self-sealing outer ring 33, allowing the hose connector 35 to be inserted into the widened opening 32. During insertion, the top cone 387 first enters the interior of the widened opening 32 and contacts the sealing plug 384. The top cone 387 pushes the sealing plug 384 backward along the sliding post 382, ​​compressing the spring 383 and separating the sealing plug 384 from the inner wall of the self-sealing outer ring 33, thereby achieving communication between the powder conveying pipe 31 and the hose connector 35. After the hose connector 35 is fully inserted into the widened opening 32, the locking core 37 is rotated, causing the solid part of the locking core 37 to engage in the groove on the outer periphery of the hose connector 35, completing the locking and fixing.

[0030] When the hose connector 35 needs to be pulled out of the widened opening 32, first rotate the locking core 37 to disengage its solid part from the groove of the hose connector 35. Then pull out the hose connector 35. As the hose connector 35 is pulled out, the top cone 387 also disengages from the interior of the widened opening 32. At this time, without the thrust of the top cone 387 on the sealing plug 384, the compressed spring 383 quickly rebounds, pushing the sliding column 382 to drive the sealing plug 384 to slide forward along the sliding column 382. The edge of the sealing plug 384 fits against the inner wall of the self-sealing outer ring 33, forming a self-sealing seal, effectively preventing material leakage and external impurities from entering the powder conveying pipe 31. This design improves the convenience and safety of pipe replacement, shortens replacement time, and reduces material loss and environmental pollution.

[0031] Reference Figure 4 and Figure 5 The height adjustment mechanism 4 includes a telescopic cylinder 41, guide wheels 42, and a height extension plate 43. The height extension plate 43 is connected to the output end of the telescopic cylinder 41 and can move up and down under the drive of the telescopic cylinder 41. The guide wheels 42 are located on the outside of the height extension plate 43 and are slidably connected to a groove opened inside the movable loading device 7. This sliding fit structure between the guide wheels 42 and the groove provides precise guidance and limitation for the movement of the height extension plate 43 during the lifting process, ensuring the smoothness and reliability of the lifting movement.

[0032] The height adjustment mechanism 4 also includes a fixed arm 44. The fixed arm 44 is fixedly connected to the outside of the height extension plate 43. A rotating column 45 is rotatably connected inside the fixed arm 44. A fulcrum block 46 is fixedly connected to the outside of the rotating column 45. A rubber fixing ring 47 is fixedly connected to the fulcrum block 46, and a rubber rotating ring 48 is rotatably connected to it. The wear-resistant hose 5 is clamped and fixed by the rubber fixing ring 47 and the rubber rotating ring 48. The rubber fixing ring 47 provides stable fixed support, while the rubber rotating ring 48 can rotate to facilitate the installation and removal of the wear-resistant hose 5. The height extension plate 43 is driven to rise and fall by the telescopic cylinder 41, which in turn drives the fixed arm 44 and the wear-resistant hose 5 clamped in the rings to rise and fall synchronously, thereby realizing precise adjustment of the conveying height.

[0033] It also includes floor 1 and temporary storage bin 2. Temporary storage bin 2 is fixedly installed on top of floor 1 for temporary storage of materials. Movable loading device 7 is installed on floor 1 and can move along the top of floor 1. Hose connector 35 is connected to one end of wear-resistant hose 5.

[0034] The movable loading device 7 is also equipped with a sliding wheel 6. The installation position of the sliding wheel 6 allows it to roll into contact with the outer wall of the wear-resistant hose 5. When the wear-resistant hose 5 is stretched or moved, the sliding wheel 6 rotates, effectively reducing frictional resistance.

[0035] The locking cylinder 37 has a groove, and the outer periphery of the hose connector 35 also has a matching groove. When it is necessary to secure the hose connector 35, the locking cylinder 37 is rotated, causing the solid part of the locking cylinder 37 to engage with the groove of the hose connector 35, forming a mechanical lock. When the locking cylinder 37 is rotated so that its groove aligns with the outer edge of the self-sealing outer ring 33, the lock is released, and the hose connector 35 can be pulled out.

[0036] It also includes a fixing component 49. The fixing component 49 is disposed on the rubber rotating retaining ring 48 and includes a support block 491 fixedly connected to the outside of the rubber rotating retaining ring 48, a rotating collar 492 rotatably connected to the support block 491, and a locking block 496 fitted by the rotating collar 492. To prevent accidental unlocking, a limiting piece 494 and a slider 495 are slidably connected inside the locking block 496, and a push spring 493 is also provided inside. The push spring 493 is used to push the slider 495 outward. When the rotating collar 492 reaches the locked position, the protrusion on its inner wall contacts the slider 495, pushing the slider 495 inward and squeezing the push spring 493. Under the elastic force of the push spring 493, the slider 495 can engage inside the limiting piece 494, forming a safety lock that prevents the locking block 496 from rotating in the opposite direction, improving operational safety.

[0037] The implementation principle of this application embodiment is as follows: When the wear-resistant hose 5 needs to be replaced, the operator rotates the engagement lock core 37 set inside the lock housing 36, so that the groove of the engagement lock core 37 is aligned with the outer edge of the self-sealing outer ring 33. At this time, the locking of the hose connector 35 is released, and the hose connector 35 can be pulled out. During the process of the hose connector 35 being pulled out, the fixing rod 385, connecting rod 386 and top cone 387 fixedly connected inside it are moved out together. When the top cone 387 is disengaged from the pushing action on the sealing plug 384, the previously compressed spring 383 rebounds, pushing the sliding column 382 to drive the sealing plug 384 forward until the edge of the sealing plug 384 is tightly fitted with the inner wall of the self-sealing outer ring 33, thereby automatically sealing the port of the powder conveying pipe 31. Through this synergistic effect of the pipe self-sealing quick-connect mechanism 3 and the sealing component 38, this utility model solves the problem of material leakage and impurity contamination caused by pipe replacement in the prior art.

[0038] When the working height of the wear-resistant hose 5 needs to be adjusted, the telescopic cylinder 41 is activated, which drives the height extension plate 43 to move up and down. Due to the precise sliding fit between the guide wheel 42 on the height extension plate 43 and the slide groove inside the movable loading device 7, the movement trajectory of the height extension plate 43 is strictly limited, thus ensuring the smoothness of the lifting process. When the wear-resistant hose 5 needs to be locked, the rotating collar 492 on the rubber rotating retainer 48 is rotated. The rotating collar 492 contacts the slider 495 and pushes the slider 495 to slide inward, squeezing the push spring 493. Under the reaction force of the push spring 493, the slider 495 is locked into the interior of the limiting piece 494, forming a lock on the locking block 496, preventing the locking block 496 from being accidentally rotated and unlocked due to vibration or misoperation. Through this synergistic effect of the height adjustment mechanism 4 and the fixing component 49, this utility model solves the problem of the hose not being securely fixed and the existence of safety hazards in the prior art.
