Description

Technical Field

[0001] This utility model relates to the field of powder loading, and in particular to a simple automatic alignment loading structure. Background Technology

[0002] In traditional powder loading systems, two pipelines are typically used: one for powder flow and the other for dust removal during loading. After the tanker truck stops at the designated location, the upper tank outlet and the tanker truck inlet are manually aligned. Once aligned, the dust removal pipeline to the tanker truck is then aligned. Only after both are properly connected can the valve be opened for powder loading. The alignment process between the tanker truck inlet and the dust removal outlet takes a considerable amount of time. If the tanker truck and the tank outlet are not aligned vertically, the tanker truck needs to be moved repeatedly to ensure it stops at the correct position. If there is a deviation between the tanker truck inlet and the tank outlet, the guide pipe will not be able to swing up and down or left and right for alignment, resulting in gaps at the interface and easy dust escape. Utility Model Content

[0003] The main objective of this invention is to provide a simple, automatic alignment loading structure. Utilizing a conical structure, it achieves automatic centering for tanker loading. During powder loading, dust may be emitted; this mechanism integrates material guiding and dust removal into a single unit.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a simple automatic alignment loading structure, wherein the powder docking interface at the upper end of the loading pipe is connected to the discharge position of the storage silo, and a loading docking connector is sleeved at the lower end outlet position of the loading pipe. The outer ring of the loading docking connector is a conical structure, and the inner ring of the loading docking connector is slidably connected to the outer wall of the loading pipe with a gap. The lower conical surface of the loading docking connector is provided with multiple dust removal and exhaust ports, and the upper opening of the loading docking connector is connected to the dust removal pipe through a steel wire hose.

[0005] In the preferred embodiment, the steel wire hose is sleeved on the loading pipe, and the dust removal pipe is sleeved on the upper part of the loading pipe. The steel wire hose is connected to the lower opening of the dust removal pipe, and the outer wall of the loading pipe and the inner wall of the steel wire hose form a dust removal channel.

[0006] In the preferred embodiment, the dust removal pipe is equipped with an inclined dust removal outlet, which is connected to the dust removal equipment.

[0007] In the preferred embodiment, a winch is also installed on one side of the dust removal pipe, and the winch is connected to the lifting lugs of the loading dock through multiple lifting ropes.

[0008] In the preferred embodiment, the lifting rope includes a first lifting rope and a second lifting rope, with the first lifting rope vertically connected to one side of the loading dock.

[0009] The second lifting rope goes horizontally around the guide wheel on the other side of the dust removal pipe and then vertically connects to the other side of the loading dock.

[0010] In the preferred embodiment, a guide pipe is also provided between the loading dock and the lower opening of the loading pipe. The guide pipe is sleeved on the outer wall of the loading pipe, and the outer wall of the guide pipe is sleeved with the inner wall of the loading dock.

[0011] In the preferred embodiment, a limiting ring is also provided inside the lower end of the loading connector, and the lower end opening of the guide tube abuts against the upper limit of the limiting ring.

[0012] This utility model provides a simple automatic alignment loading structure. This loading mechanism utilizes the automatic alignment effect of the conical body of the loading connector (7) to achieve centering adjustment when there is a deviation in the tank car's parking position. It can rely on the falling of the loading mechanism and the weight of the conical section itself to make it fall onto the tank car's feed inlet. It has an automatic correction effect in the case of a small deviation. Attached Figure Description

[0017] Example 1

[0018] like Figure 1-2 As shown, a simple automatic alignment loading structure is provided. The powder interface 101 at the upper end of the loading pipe 1 is connected to the discharge position of the storage silo. The lower end of the loading pipe 1 is fitted with a loading connector 7. The outer ring of the loading connector 7 is conical. The inner ring of the loading connector 7 is slidably connected to the outer wall of the loading pipe 1 with a gap. The lower conical surface of the loading connector 7 is provided with multiple dust removal and exhaust ports 701. The upper opening of the loading connector 7 is connected to the dust removal pipe 8 through a steel wire hose 4.

[0019] Automatic alignment of the tanker loading mechanism is achieved. A hollow conical loading connector 7, with a dust extraction port 701 on its inclined surface, allows airborne dust to be sucked away through the hollow cone during the feeding process. The loading pipe 1 at the upper center of the loading mechanism, and the intermediate guide pipe 5, enable the vertical movement of the lower loading connector 7, ensuring the powder flows smoothly within the guide pipe 5.

[0020] A short connector larger than the diameter of the guide pipe is installed at the upper part of the loading connector 7 of the lower conical body of the loading mechanism and at the lower end of the upper connecting part of the mechanism. A polyurethane steel wire hose 4 is installed on top of it. The outside of the guide pipe 5 and the polyurethane steel wire hose 4 form a closed cavity to realize the flow pipeline for dust removal. The lower loading connector 7 of the loading mechanism moves up and down by using 2 or 4 steel wire ropes attached to the hoisting system. The forward and reverse rotation of the hoisting system realizes the up and down movement of the loading connector 7. The hoisting system has a self-locking function to ensure that the cone will not fall when the hoisting system is not in operation, thus ensuring inherent safety.

[0021] In the preferred embodiment, the steel wire hose 4 is sleeved on the loading pipe 1, and the dust removal pipe 8 is sleeved on the upper part of the loading pipe 1. The lower opening of the steel wire hose 4 and the dust removal pipe 8 are connected, and the outer wall of the loading pipe 1 and the inner wall of the steel wire hose 4 form a dust removal channel.

[0022] Steel wire hose 4: Sleeve over the loading pipe 1, serving a connecting and sealing function to ensure that dust does not escape from the gap between the loading pipe 1 and the outside. The steel wire hose 4 has a certain degree of flexibility and strength, enabling it to accommodate the vertical movement of the loading connector 7 while ensuring a tight seal.

[0023] Dust collection pipe 8: Located at the upper part of the loading pipe 1, its lower end is connected to the steel wire hose 4. The function of dust collection pipe 8 is to draw the dust generated during the loading process into the external dust collection equipment through the internal airflow, preventing dust pollution of the environment.

[0024] The outer wall of the loading pipe 1 and the inner wall of the steel wire hose 4 form a dust removal channel: a closed cavity is formed between the outer wall of the loading pipe 1 and the inner wall of the steel wire hose 4. This cavity serves as a dust removal channel, which guides dust from the dust removal exhaust port 701 of the loading connector 7 into the dust removal pipe 8, and is eventually led to the dust removal equipment for treatment.

[0025] Once the tanker truck stops at the designated location, the winch 2 drives the loading dock 7 to descend. The conical structure of the loading dock 7 will automatically align with the tanker truck's feed inlet and make minor adjustments according to the shape of the tanker truck's feed inlet to ensure precise docking.

[0026] During the loading process, the powder enters the tanker through the loading pipe 1, while the dust extraction port 701 of the loading dock 7 will extract the dust generated during the loading process. The dust is then guided to the external dust removal equipment for treatment through the dust removal channel composed of the steel wire hose 4 and the dust removal pipe 8.

[0027] After loading is completed, winch 2 lifts loading connector 7, closes unloading switch valve, and continues dust removal for a period of time to ensure that all dust has fallen into the tanker or been treated by dust removal equipment.

[0028] In the preferred embodiment, the dust removal pipe 8 is provided with an inclined dust removal outlet 801, which is connected to the dust removal equipment.

[0029] The dust collection pipe 8 is designed with an inclined dust collection outlet 801, located on one side of the pipe and connected to external dust collection equipment. This inclined design helps guide dust generated during loading from the dust collection exhaust port 701 of the loading dock 7 into the dust collection pipe 8, and then smoothly discharges it into the dust collection equipment for treatment through the dust collection outlet 801. The inclined structure effectively utilizes gravity, ensuring that dust does not accumulate inside the pipe as it passes through the dust collection pipe 8, but flows smoothly to the dust collection equipment, improving dust collection efficiency and reducing the risk of pipe blockage. Furthermore, this design simplifies the connection of the dust collection system, allowing the dust collection equipment to directly connect to the dust collection pipe 8 without additional complex piping, reducing system complexity and maintenance costs.

[0030] In the preferred embodiment, a winch 2 is also provided on one side of the dust removal pipe 8. The winch 2 is connected to the lifting lug 6 of the loading dock 7 via multiple lifting ropes. The lifting ropes include a first lifting rope 3 and a second lifting rope 9. The first lifting rope 3 is vertically connected to one side of the loading dock 7; the second lifting rope 9 is horizontally wrapped around the guide wheel 901 on the other side of the dust removal pipe 8 and then vertically connected to the other side of the loading dock 7.

[0031] A winch 2 is installed on one side of the dust collection pipe 8. This winch 2 is used to control the up and down movement of the loading dock 7. The winch 2 is connected to the lifting lugs 6 on the loading dock 7 via multiple lifting ropes, ensuring that the loading dock 7 can be raised and lowered smoothly and accurately. Specifically, the lifting ropes are divided into two parts: a first lifting rope 3 and a second lifting rope 9. The first lifting rope 3 is directly and vertically connected to one side of the loading dock 7, while the second lifting rope 9 first passes horizontally around the guide wheel 901 located on the other side of the dust collection pipe 8, and then is vertically connected to the other side of the loading dock 7.

[0032] This design allows the loading connector 7 to maintain balance during descent, and utilizes the forward and reverse rotation of the winch 2 to move the loading connector 7 up and down. The winch 2 has a self-locking function, ensuring that the loading connector 7 will not accidentally fall due to its own weight when not in operation, thus guaranteeing operational safety. After the tank truck stops at the designated position, the winch 2 drives the loading connector 7 to descend. The conical structure of the loading connector 7 automatically aligns with the tank truck's feed inlet and makes fine adjustments according to the shape of the tank truck's feed inlet to ensure precise docking. After loading is completed, the winch 2 raises the loading connector 7, closes the unloading switch valve, and continues dust removal for a period of time to ensure that all dust has fallen into the tank truck or been processed by the dust removal equipment.

[0033] This dual-lifting-rope design not only improves the stability and accuracy of the vertical movement of the loading connector 7, but also ensures automatic alignment during loading, reducing the need for manual intervention and increasing work efficiency. Furthermore, the application of the guide wheel 901 allows the second lifting rope 9 to smoothly change direction, avoiding friction and wear between ropes and extending the system's service life. Overall, this design simplifies the operation process, enhances the system's reliability and safety, and is suitable for various powder loading applications.

[0034] In the preferred embodiment, a guide pipe 5 is provided between the loading connector 7 and the lower opening of the loading pipe 1. The guide pipe 5 is sleeved on the outer wall of the loading pipe 1, and the outer wall of the guide pipe 5 is sleeved with the inner wall of the loading connector 7.

[0035] A guide pipe 5 is installed between the loading connector 7 and the lower opening of the loading pipe 1. The guide pipe 5 is sleeved on the outer wall of the loading pipe 1, and the outer wall of the guide pipe 5 forms a sleeve structure with the inner wall of the loading connector 7. This design ensures that the powder can flow smoothly from the inside of the loading pipe 1 to the loading connector 7, and then enter the tanker through the loading connector 7. The function of the guide pipe 5 is not limited to guiding the flow of powder; it also provides additional support and connection between the loading connector 7 and the loading pipe 1, ensuring that the loading connector 7 remains stable when moving up and down.

[0036] Specifically, the design of the guide pipe 5 allows the loading connector 7 to move freely within a certain range while maintaining good alignment with the loading pipe 1. When the winch 2 drives the loading connector 7 to descend, the guide pipe 5 moves along with the loading connector 7, ensuring that the powder can flow continuously and stably into the tanker. In addition, the sleeve structure between the outer wall of the guide pipe 5 and the inner wall of the loading connector 7 forms a closed space. This space, together with the wire hose 4, constitutes a dust removal channel, effectively preventing dust from escaping from the gap between the loading connector 7 and the loading pipe 1.

[0037] To further enhance the stability and safety of the system, a limiting ring 703 is also provided inside the lower end of the loading connector 7 at the interface 702. The lower opening of the guide tube 5 abuts against the limiting ring 703, which serves as a limiting element. This prevents the guide tube 5 from over-extending or detaching during the descent of the loading connector 7, ensuring the reliability of the entire system during operation.

[0038] In summary, the design of the feed pipe 5 not only optimizes the powder conveying path and improves loading efficiency, but also enhances the system's stability and sealing through its tight fit with the loading connector 7 and the loading pipe 1, effectively preventing dust leakage and improving overall environmental performance. This design simplifies the alignment operation during loading, reduces manual intervention, and is suitable for various powder loading scenarios, significantly improving work efficiency and safety.

[0039] In the preferred embodiment, a limiting ring 703 is also provided inside the lower end of the loading connector 7 at the interface 702, and the lower end opening of the guide pipe 5 abuts against the upper limit of the limiting ring 703.

[0040] A limiting ring 703 is installed inside the mating interface 702 at the lower end of the loading connector 7. The function of this limiting ring 703 is to provide a clear stop point for the guide tube 5, ensuring that the lower opening of the guide tube 5 can stably abut against it, thereby preventing the guide tube 7 from over-extending or detaching during the descent of the loading connector 7. This design ensures a tight fit between the guide tube 5 and the loading connector 7, enhancing the stability and reliability of the entire system.

[0041] Example 2

[0042] like Figure 1-2 As shown, this mechanism utilizes the automatic centering effect of a conical structure. A hollow conical loading connector 7 is used, with the required dust removal and exhaust port 701 opened on the sloping side. A section of easily worn guide pipe 5 is placed in the middle. The upper part uses a loading pipe 1 made of inner and outer steel pipes. The center position is used to guide the falling powder, and the outer layer is used for dust removal pipeline. The dust removal pipeline is sealed with polyurethane steel wire hose 4 to achieve airtightness. The winch 2 realizes the up and down movement of the conical body and automatically aligns it with the loading hole of the tanker truck, realizing the dual effect of powder loading or dust removal.

[0043] The working process of the mechanism is as follows: The tanker is parked at the lower end of the tank body discharge port, ensuring that the tanker's inlet and the tank body discharge port are basically on the vertical line with a deviation of less than 50mm. The winch 2 is driven to release the lower loading connector 7 of the loading mechanism to fall. The conical body of the loading connector 7 contacts the tanker's inlet and inserts. Due to the deviation, the conical body is not in the center of the tanker's inlet. As the loading connector 7 continues to fall, due to its own weight, the conical body of the loading connector 7 shifts with the tanker's inlet and completely blocks the tanker's inlet. With the opening of the exhaust pipe valve, the exhaust pipe operates normally, drawing the air inside the tanker into the dust removal exhaust port 701 on the inclined surface of the loading connector 7, and then into the dust removal pipe of the bag filter through the guide pipe 5 and the polyurethane jacket pipe.

[0044] After the exhaust system is activated, the unloading valve at the bottom of the tank is opened. The powder flows along the loading pipe 1 to the center of the loading dock 7 and falls into the tank truck. The dust carried by the falling powder at the inlet enters the dust extraction port 701 on the inclined surface of the loading dock 7. As the dust accumulates, it falls into the tank truck by its own weight through the dust extraction port 701. Lighter dust enters the bag filter through the dust collection pipeline and finally falls into the powder space at the top of the tank. After loading is complete, the unloading valve is closed, the hoisting system is activated, the loading dock 7 slowly rises, the tank truck is moved, and loading continues at the next inlet until the tank truck is full. The unloading valve is then closed, the cone is raised, and the exhaust pipe valve is closed.

[0045] After the tanker is full, close the unloading switch valve and continue dust removal for about 5 minutes. Gradually reduce the frequency of the dust collector fan so that the dust accumulated in the dust removal pipeline falls into the tanker by its own weight. After the frequency is reduced to below 10Hz, close the exhaust valve of the loading mechanism and start the hoisting system to lift the conical section up to the highest point.

[0046] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
