Description

Technical Field

[0001] The invention relates to the technical field of ash storage and conveying, and 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 system of the ash conveying station includes: dust removal and exhaust system, air compressor system, gas 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 materials transported include: cement, barite, limestone, soil powder and other platform drilling and completion materials. The materials are packed in ton bags and put into storage, and then put into the ground tank through the bag breaking operation. At the same time, they are 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 material is transported to the ship's ash tank compartment through the ash conveying station conveying system to complete the ship transportation operation.

[0003] Since bag breaking and material preparation operations take a long time, and the ash handling station has limited equipment resources, the storage capacity of the 12 ash storage tanks cannot meet the current ash handling operation needs. When the platform service ships come to the port in batches, only 1 to 2 consecutive ships can empty the ash storage tanks, causing the remaining ships to queue up and wait for the manual bag breaking operation at the ash handling station, which takes a long time to wait and delays the ship's schedule.

[0004] In emergency situations, tank trailers for powder and granular materials 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 tank trailers for powder and granular materials is long, and is often delayed by uncertain factors such as road traffic. In addition, the loading of ash into the tank by tank trailers for powder and granular materials occupies the equipment resources of the ash transport 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 ship. After the ash storage tank at the ash conveying station is full, the ash can be conveyed to the powder and granular material tank trailer that is kept for a long time on site 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 trailer can temporarily store ash. The tank trailer can then directly convey ash to the ship without occupying the resources of the ash conveying station, so that the ash replenishment operation at the ash conveying station and the tank trailer conveying operation to the ship can be carried out simultaneously, 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 manual bag breaking time that affect the ship's schedule.

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

[0046] During use, there are two processes: the ash conveying station conveys ash to the tank truck and the tank truck conveys ash to the ship. When the ash conveying station conveys ash to the tank truck, first connect the ash conveying port of the ash conveying station with the feed port of the tank truck through a hose; connect the venting vent hole 221 with the venting pipe of the ash conveying station through a hose; open the fourth butterfly valve 230 and the fifth butterfly valve 240, open the butterfly valve of the venting pipeline of the ash conveying station, open the booster device and dust removal equipment of the dry powder tank truck of the ash conveying station to convey ash to the three-purpose workboat, and convey ash to the tank truck. Since the venting pipeline of the tank truck is in an open state, the tank body is not affected by pressure; and since the venting pipeline of the tank truck is connected to the venting pipeline of the ash conveying station, a small amount of dust passes through the venting pipeline and passes through the secondary dust removal device of the ash conveying station for dust removal treatment, achieving zero emission. Since the volume of the tank truck is fixed, the staff calculates and operates the ash conveying station equipment to fix the ash conveying amount (the ash conveying station has a dynamic weighing system) to ensure the fixed ash capacity of the tank truck. The ash conveying station completes the ash conveying to the tank truck, allowing the tank truck to temporarily store a certain amount of ash and improve the ash storage capacity of the ash conveying station.

[0047] When the tank truck delivers ash to the ship, first connect the tank truck discharge port to the ash delivery inlet interface 341 through a hose; connect the ash delivery discharge interface 342 to the ship ash tank inlet through a hose; connect the venting pipeline 345 to the guide pipe of the ash delivery station through a hose; then connect the external booster air source main pipe joint 310 to the portable air compressor or the ash delivery station air compressor air source pipe; then open the third butterfly valve 363 and the ash delivery station venting pipeline valve, open the first butterfly valve 361 and the second butterfly valve 362, open the tank truck ash delivery air compressor to start ash delivery, and open the portable air compressor or the ash delivery station air compressor to start pressurized ash blowing. The tank truck tank body 100 reaches the pressure standard for delivering ash to the ship through the booster ash conveyor 300, realizing 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 also includes: a clamp check valve 380, which is arranged on the main pipe 340 and is located between the second T-type three-way 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, wherein a flow channel is provided inside, an opening is provided at the upper end of the cylinder body, and a removable upper cover 391 is provided 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, it 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, it further includes: a forklift hole 410, which is disposed on the base 400 to facilitate 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.
