Description

Technical Field

[0001] The utility model relates to the technical field of ash storage and conveying, in particular to a power assist device for conveying ash from a dry powder tank truck to a three-purpose work boat. Background Art

[0002] The ash conveying station is specially built to provide ash conveying services for offshore oil drilling platforms. The entire ash conveying station system includes: dust removal and exhaust system, air compressor system, air storage tank system, ash storage tank system, weighing system, power distribution and centralized control system, external transmission and recovery pipeline system, etc. The types of ash conveyed include: platform drilling and completion materials such as cement, barite, limestone, and soil powder. The materials are packed in ton bags and stored in the warehouse. After the bags are broken, they are transported to the ground tank and transported to the ash storage tank through the ash conveying line to complete the material preparation operation; after waiting for the platform service ship to arrive at the port, the ash is transported to the ship's ash tank compartment through the ash conveying station conveying system to complete the ship transportation operation.

[0003] Due to the time-consuming bag-breaking and material preparation process, and the limited equipment resources at the ash handling station, the storage capacity of the 12 ash storage tanks could not meet the current ash handling needs. When the platform service vessels arrived in large numbers, only one or two vessels could empty the ash storage tanks in a row. This caused the remaining vessels to queue for manual bag-breaking at the ash handling station, resulting in long wait times and delayed departures.

[0004] In emergency situations, powder and granular material tank trailers can be provided to deliver ash to the port, and the tank trucks can directly complete the loading of ash into the tank through their own ash unloading system. However, the transportation distance of the powder and granular material tank trailers is long and is affected by uncertain factors such as road traffic, which often causes delays. In addition, the loading of the powder and granular material tank trailers into the tank occupies the equipment resources of the ash conveying station, and the overall efficiency still cannot meet the ship schedule requirements.

[0005] A power assist device for conveying ash from a dry powder tank truck to a three-purpose work vessel. After the ash storage tank at the ash conveying station is full, the ash can be conveyed to a powder and granular material tank trailer that is kept on site for a long time through the ash conveying system of the ash conveying station. The ash types stored in the tank trailers with different numbers are fixed, and the ash storage tonnage of each tank trailer is recorded, so that the tank trailers can temporarily store ash. The tank trailers can then directly convey ash to the ship without occupying the resources of the ash conveying station, and the ash replenishment operation at the ash conveying station and the tank trailer ship transportation operation can be carried out simultaneously, thereby greatly improving the efficiency of the ash conveying operation and solving the problem of insufficient ash storage resources at the ash conveying station and long time for manual bag breaking that affects the ship's schedule.

[0045] The pressurized ash conveyor 300: The starting end of the external pressurized air source main pipe connector 310 is used to connect to the air source of a portable air compressor or an ash conveying station air compressor. A first T-shaped three-way valve 311 is provided at the end of the external pressurized air source main pipe connector 310. As a preferred embodiment, a first ball valve 312 for controlling on / off is provided on the external pressurized air source main pipe connector 310. The starting ends of the external pressurized air source front-end soot blowing pipe 320 and the external pressurized air source terminal soot blowing pipe 330 are respectively connected to the first T-shaped three-way valve 311. As a preferred embodiment, a second ball valve 321 and a third ball valve 331 are respectively provided on the external pressurized air source front-end soot blowing pipe 320 and the external pressurized air source terminal soot blowing pipe 330. The main pipe 340 is arranged at the rear of the external pressurized air source main pipe joint 310. An ash feeding interface 341 for connecting to the ash feeding pipe of the tank truck tank body is provided at the front end of the main pipe 340; an ash discharging interface 342 for connecting to the ash feeding hose of the ship is provided at the end of the main pipe 340; a first air blowing interface 343 and a second air blowing interface 344 are respectively arranged at the middle and rear of the main pipe 340. The first air blowing interface 343 and the second air blowing interface 344 are respectively connected to the external pressurized air source front end soot blowing pipe 320 and the external pressurized air source end soot blowing pipe 330, and are used to blow soot from the front and rear of the main pipe 340. As a preferred embodiment, the first air blowing interface 343 and the second air blowing interface 344 are respectively connected to the external pressurized air source front end soot blowing pipe 320 and the external pressurized air source end soot blowing pipe 330 through a hose 350. A vent line 345 is located in the middle of the main pipe 340, opposite the first air blow port 343. A vent line port 345a is provided at the free end of the vent line 345. This port 345a is connected to the ash handling station piping outlet or the tanker tank inlet 110. A first butterfly valve 361 and a second butterfly valve 362 are located in the middle and rear of the main pipe 340, respectively. The first butterfly valve 361 is located behind the first air blow port 343, and the second butterfly valve 362 is located in front of the second air blow port 344. A third butterfly valve 363 is located on the vent line 345.

[0046] During operation, the system involves two processes: transferring ash from the ash handling station to the tank truck and from the tank truck to the vessel. When transferring ash from the ash handling station to the tank truck, the ash handling station's ash delivery port is first connected to the tank truck's feed port via a hose. The vent vent 221 is then connected to the ash handling station's vent pipe via a hose. The fourth and fifth butterfly valves 230 and 240 are then opened, opening the butterfly valves on the ash handling station's vent line. The booster and dust removal equipment for transferring ash from the ash handling station's dry powder tank truck to the multi-purpose workboat are then activated, allowing ash to be delivered to the tank truck. Since the tank truck's vent line is open, the tank is not subject to pressure. Furthermore, since the tank truck's vent line is connected to the ash handling station's vent line, a small amount of dust can pass through the vent line and into the ash handling station's secondary dust removal device for dust removal, achieving zero emissions. Since the tank truck's volume is fixed, staff calculate and operate the ash handling station's equipment to deliver a fixed ash volume (the ash handling station has a dynamic weighing system) to ensure the tank truck holds a fixed ash volume. The ash conveying station is used to transport ash to the tank truck, allowing the tank truck to temporarily store a fixed amount of ash, thereby improving the ash storage capacity of the ash conveying station.

[0047] When a tank truck is delivering ash to a ship, first connect the tank truck's discharge port to the ash delivery inlet interface 341 via a hose; then connect the ash delivery outlet interface 342 to the ship's ash tank inlet via a hose; then connect the vent line 345 to the ash delivery station's material guide pipe via a hose; then connect the external booster air source main pipe connector 310 to the portable air compressor or the ash delivery station's air compressor air source pipe; then open the third butterfly valve 363 and the ash delivery station's vent line valve, open the first butterfly valve 361 and the second butterfly valve 362, turn on the tank truck's ash delivery air compressor to begin ash delivery, and turn on the portable air compressor or the ash delivery station's air compressor to begin pressurized soot blowing. The tank truck's tank body 100 reaches the pressure standard for ash delivery to the ship through the pressurized ash delivery device 300, enabling direct ash delivery to the ship. By extending the ash conveying station vent pipeline to other berths at the terminal and using a mobile air compressor to increase the air pressure, it is also possible to simultaneously convey ash to multiple berths and multiple ships, greatly improving the ash conveying efficiency.

[0051] In another embodiment, it further includes: a clamped check valve 380, which is arranged on the main pipe 340 and located between the second T-type tee 371 and the first butterfly valve 361, and is used to close when the front end of the main pipe 340 is blocked by dust, so as to prevent pressure from returning to the tank body of the tank truck.

[0052] In another embodiment, it also includes: an impurity catcher 390, which is arranged in the rear middle part of the main pipe 340, between the first butterfly valve 361 and the second butterfly valve 362, for daily cleaning and maintenance; wherein, the impurity catcher 390 includes: a cylinder body 392, which has a flow channel inside, an opening at the upper end of the cylinder body, and a removable upper cover 391 at the opening; a hemispherical filter screen 393, which is arranged in the flow channel and adapted to the flow channel, and the concave surface of the hemispherical filter screen is opposite to the flow direction of the ash; wherein, a sealing rubber ring 394 is provided between the opening and the upper cover 391.

[0053] In another embodiment, the system further includes: a base 400 , which is disposed directly below the pressurized ash conveyor 300 and is used to support the pressurized ash conveyor 300 .

[0054] In another embodiment, the present invention further comprises: a forklift hole 410 provided on the base 400 for facilitating the movement of the pressurized ash conveyor.

[0055] In another embodiment, the first air blowing interface 343 and the second air blowing interface 344 are connected to the front-end soot blowing pipe 320 of the external pressurized air source and the end-end soot blowing pipe 330 of the external pressurized air source through a hose 350 respectively.
