Description

Technical Field

[0001] The utility model relates to the technical field of port equipment transportation design, in particular to a mineral powder conveying and ship loading system. Background Technique

[0002] At present, the main equipment for transporting bulk materials in ports is a ship loader, which generally consists of a boom belt conveyor, a transition belt conveyor, a telescopic chute, a tail car, a traveling device, a gantry, a tower, a pitching device, a slewing device, etc. For bulk cargo in ports, the telescopic chute and the telescopic distributor are relatively commonly used for the ship loader; among them, the telescopic distributor is used to solve the problem of high-flow ship loading operations for loose materials. Such ship loaders are too large in size and are generally used for bulk material loading in large ports.

[0003] For large ports, using a ship loader for the ship loading operation of loose materials for large cargo ships in sea transportation and river transportation can quickly complete the ship loading in a short time. However, due to market demand and geographical conditions restrictions, some bulk materials (such as mineral powder) need to be transported by general cargo ships in small ports and terminals. Currently, there are the following technical problems in loading mineral powder bulk materials onto small ports or terminals and general cargo ships: (1) The space of the port or terminal is narrow: For small ports or terminals, if the terrain is narrow, ordinary ship loaders cannot be installed in such places. At this time, simple and convenient ship loading equipment is needed. (2) The port or terminal is not fixed: In some ports or terminals affected by the water level, it is necessary to go from a high (low) water level terminal to another low (high) water level terminal for ship loading. If the ship loading equipment is fixed or inconvenient to disassemble at this time, it can only load ships at a fixed point, greatly increasing the difficulty of ship loading. (3) High dust and dust flying: Since mineral powder is a high-dust material and at the same time needs to be loaded onto a general cargo ship, the general cargo ship cannot be completely enclosed when loading mineral powder, and a large amount of dust will appear at that time. Content of the Utility Model

[0004] Aiming at the above deficiencies existing in the prior art, the purpose of the utility model is to provide a mineral powder conveying and ship loading system, which solves the problems that the existing ship loader is too large in size and is not convenient to install and use in small ports or terminals with narrow terrain, and the existing ship loading equipment is not convenient to disassemble and a large amount of dust is generated during the transportation of mineral powder.

[0019] In the figure, powder transport vehicle 1, bag filter 2, fan 3, blanking dust-proof cover 4, material conveying pipeline 5, dust collection pipeline 6, return material conveying pipeline 7, feed inlet 8, dust collection port 9, return material port 10, cargo ship 11, dust-proof cloth strip 12, floating dock 13, support frame 14. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following combines specific embodiments and drawings to further describe the specific embodiments of the utility model in detail. Embodiment

[0021] As Figure 1 shown, a powder conveying and ship loading system includes a material conveying pipeline 5, a blanking dust-proof cover 4, a bag filter 2 and a fan 3. The discharge end of the material conveying pipeline 5 is connected to the feed inlet 8 at the top of the blanking dust-proof cover 4, and the feed end is used to connect to the powder transport vehicle 1 for feeding; the air inlet of the bag filter 2 is connected to the dust collection port 9 at the top of the blanking dust-proof cover 4 through the dust collection pipeline 6, and the discharge port of the bag filter 2 is connected to the air outlet of the fan 3; the air outlet of the fan 3 is connected to the return material port 10 at the top of the blanking dust-proof cover 4 through the return material conveying pipeline 7; an air compressor is installed on the powder transport vehicle 1, and the powder in the powder transport vehicle 1 can be conveyed into the cargo ship 11 through the material conveying pipeline 5 and the blanking dust-proof cover 4.

[0022] During specific implementation, a circle of dust-proof cloth strips 12 is wound around the lower edge of the blanking dust-proof cover 4. Since the cloth strips are flexible, when docking with the cargo ship 11, the gap between the dust-proof cloth strips 12 and the cargo ship 11 can be reduced, effectively preventing excessive dust, further improving the dust-proof effect, reducing the dust pollution in the air, and being beneficial to environmental protection and human health.

[0023] During specific implementation, the dust-proof cloth strip 12 is made of a transparent material. Since ore powder is a high-dust powder material, in order to prevent a large amount of dust from being generated when loading the ore powder onto the ship, it is necessary to minimize the gap between the dust-proof cloth strip 12 and the cargo ship 11 as much as possible. Therefore, setting the dust-proof cloth strip 12 to be made of a transparent material can facilitate clearly observing the feeding situation of the ore powder dust. If a material blockage situation is observed, it can be dealt with in a timely manner.

[0024] During specific implementation, the tops of the feeding port 8, the dust collection port 9, and the return material port 10 protrude upward to form hollow cylinders with inner diameters consistent with the diameters of the feeding port 8, the dust collection port 9, and the return material port 10 respectively, so as to facilitate the installation of the pipeline. Such a setting facilitates the installation and fixation of the pipeline.

[0025] During specific implementation, the material conveying pipeline 5, the dust collection pipeline 6, and the return material conveying pipeline 7 are respectively sleeved on the corresponding hollow cylinders and locked by clamps. In this way, it can prevent the feeding dust-proof cover 4 from falling due to gravity, and this locking method is convenient for installation and disassembly, and can realize ship loading in different places, reducing the ship loading difficulty.

[0026] During specific implementation, the bag filter 2 and the fan 3 are installed on the floating dock 13. This can avoid the influence of water level factors on the ore powder transportation. Because if installed on the shore, the position is fixed. If the water level is relatively low, first, the pipeline is not long enough to reach the ship, and the ore powder transportation cannot be realized. Second, the three pipelines are vertically downward, and the dust collection pipeline 6 may have poor dust collection effect due to insufficient negative pressure. If the water level is too high, the upward angle of the three pipelines is too large, and the material conveying pipeline 5 and the return material conveying pipeline 7 may not be able to successfully convey the material into the cargo ship 11 due to insufficient pressure, but instead may cause material blockage. However, if set on the floating dock 13, the water levels of the floating dock 13 and the cargo ship 11 are at the same height, and the above situations will not occur.

[0027] During specific implementation, the discharge port of the bag filter 2, the air outlet of the fan 3, and the return material conveying pipeline 7 are connected through a tee pipeline. This structure is simple and easy to implement.

[0028] During specific implementation, the fan 3 adopts a Roots blower to facilitate providing sufficient wind force.

[0029] During specific implementation, the material conveying pipeline 5, the dust collection pipeline 6, and the return material conveying pipeline 7 are fixed by a support frame 14 welded to the barge 13. The support frame 14 includes a vertical rod and a horizontal rod. The horizontal rod is welded to the top of the vertical rod, and three mounting through holes are formed in the horizontal rod along the length direction of the horizontal rod. All the pipelines pass through the mounting through holes, and pipe clamps are arranged on the pipelines at both ends of the mounting through holes to prevent the pipelines from shifting. In this way, the pipelines can be fixed through the support frame 14, thereby fixing the blanking dust hood 4. By adjusting the fixing positions of the pipelines and the support frame 14, the blanking dust hood 4 can be suspended directly above the cargo ship 11, thus realizing the loading of mineral powder onto the ship.

[0030] During specific implementation, a screw auger can also be used to replace the fan 3 and the return material conveying pipeline 7, and the feed end of the screw auger is connected to the discharge port of the bag filter 2, and the discharge end is connected to the cargo ship 11. Such a return material conveying method is also relatively simple and easy to implement.

[0031] Working principle: The mineral powder transport vehicle 1 of the present utility model is parked on the shore. The bag dust collector 2 and the fan 3 are installed on the floating dock 13, and all pipelines are connected to the blanking dust-proof cover 4. Before the mineral powder is transported, by arranging the support frame 14 on the floating dock 13, all pipelines can be fixed, so that the blanking dust-proof cover 4 is just suspended directly above the cargo ship 11, thus realizing the loading of mineral powder onto the ship. When the present utility model transports the mineral powder, the air compressor on the mineral powder transport vehicle 1 provides power, and the mineral powder can be transported through the feeding pipeline 5 into the feeding port 8 of the blanking dust-proof cover 4, and then fall into the cargo ship 11 from the bottom of the blanking dust-proof cover 4, realizing the transportation and loading of the mineral powder onto the ship. Among them, the blanking dust-proof cover 4 can effectively prevent a large amount of dust from polluting the air. Then, through the negative pressure of the bag dust collector 2, the dust is sucked out from the dust collection port 9 through the dust collection pipeline 6, and the absorption of the mineral powder dust can be realized. The absorbed dust passes through the filter bag in the bag dust collector 2, and the mineral powder dust adheres to the outer surface of the filter bag, while the gas enters the upper box body through the filter bag, and then through the exhaust pipeline, and is discharged into the atmosphere by the fan. Finally, the dust on the outer surface of the filter bag falls off from the outer surface of the filter bag under the action of mechanical force and falls into the ash hopper, thus realizing the gas-solid separation. Finally, the mineral powder dust in the ash hopper falls into the return material conveying pipeline 7 connected to the air outlet of the fan 3 through the dividing wheel, and the mineral powder dust is blown back into the blanking dust-proof cover 4 by the blowing of the fan 3. Thus, the removal and recycling of the dust are realized. In addition, a circle of transparent dust-proof cloth strips 12 is surrounded at the lower edge of the blanking dust-proof cover 4, which can effectively prevent excessive dust, further improve the dust-proof effect, reduce the dust pollution in the air, is beneficial to environmental protection and human health, and at the same time is convenient for clearly observing the blanking situation of the mineral powder dust. Hollow cylinders with inner diameters consistent with the diameters of the feeding port 8, the dust collection port 9, and the return material port 10 are arranged at the tops of the feeding port 8, the dust collection port 9, and the return material port 10, which is beneficial to realizing the installation and fixation of the pipelines. And all pipelines and the hollow cylinders are locked through clamps. In this way, it can prevent the blanking dust-proof cover 4 from falling due to gravity, and this locking method is convenient for installation and disassembly, and can realize loading at different places, reducing the loading difficulty.

[0032] The mineral powder conveying device of the present utility model has a simple structure and occupies a small space, and is also applicable to small ports or docks with narrow terrain. It has a high universality and solves the problem that the existing ship loading machine has a too large volume and is not convenient for installation and use in small ports or docks with narrow terrain. Moreover, through the settings of the blanking dust-proof cover, the bag dust collector and the fan, the present utility model can effectively prevent dust from polluting the air and at the same time realize the recycling of the mineral powder dust. In addition, all pipelines and structures of the present utility model are detachably connected, which is convenient for disassembly and transportation, and can realize loading at different points, reducing the loading difficulty. It solves the problem that the port or dock is not fixed and loading needs to be carried out at different locations.

[0033] It should be noted that the bag filter used in the present utility model is a prior art, including a box body, filter bags, ash hoppers, dividing wheels, etc., which will not be elaborated herein.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than limiting them. Those of ordinary skill in the art should understand that any modifications or equivalent replacements made to the technical solutions of the present utility model without departing from the purpose and scope of the present technical solutions shall be covered within the scope of the claims of the present utility model.
