Description

Technical Field

[0001] The utility model relates to an anti-pollution ship loading quick connector, belonging to the technical field of ship loading connectors. Background Art

[0002] In recent years, with the development of the shipping market, more and more goods such as slag powder and cement are transported by ships. When loading slag powder, cement and other powdered goods, they are sprayed into the cargo hold of the ship through the conveying pipeline by special tank trucks with their own high-pressure air. During the loading process, the conveying pipeline interface and the ship's loading port are simply connected. The connecting pipeline will not only generate a lot of dust under the action of high-pressure air, but also easily burst and cause the pipeline interface to fly out of the loading port, causing personal injury.

[0003] The current connection method used for loading pipelines for powdery goods such as slag powder and cement is: an "L"-shaped steel pipe is connected to the cargo conveying hose, the short head of the "L"-shaped steel pipe is directly inserted into the cargo input port of the ship's cargo hold cover, the "L"-shaped steel pipe is tied to the ship's cargo hold cover with a portable bandage, and the gap between the "L"-shaped steel pipe and the loading hole is blocked with clothing. When replacing the powdery cargo tank truck, the hose is temporarily folded manually to prevent cargo spillage.

[0004] The existing connection methods have the following problems: the pipe joints are only fixed with portable bandages, the connection speed is slow, the fixation is not reliable, and the interface is not tightly sealed. When replacing vehicles, removing pipes, or when pipes are damaged, there is no check valve in the pipes, which will cause the water slag powder to flow back due to the high pressure in the cabin, affecting the air environment and causing cargo losses. Utility Model Content

[0005] The utility model aims to provide an anti-pollution ship loading quick connector, which can not only realize efficient and firm connection with the ship cargo hold, but also prevent slag powder from flowing back and leaking out due to the high pressure in the cargo hold when the loading vehicle is replaced or the pipeline is damaged, thereby protecting the ecological environment, ensuring the personal safety of workers, improving work efficiency, and solving the problems existing in the background technology.

[0006] The technical solution of the utility model is:

[0007] A pollution-proof ship loading quick connector comprises a fixed flange, an L-shaped pipeline, a one-way valve outlet flange, a gravity one-way valve, a one-way valve inlet flange, a connecting pipeline and a quick connector female head, wherein two ends of the gravity one-way valve are respectively connected to the L-shaped pipeline and one end of the connecting pipeline through the one-way valve outlet flange and the one-way valve inlet flange, and a one-way valve inspection port is arranged above the gravity one-way valve; a quick connector cargo hold input port is arranged at the other end of the L-shaped pipeline, the quick connector cargo hold input port is inserted into a cargo hold reserved hole of a cargo hold hatch cover, and is connected to the cargo hold hatch cover through a fixed flange; a quick connector female head is arranged at the other end of the connecting pipeline, and the quick connector female head is connected to a quick connector male head of a conveying pipeline.

[0008] A one-way valve gravity valve disc is arranged inside the gravity one-way valve. The one-way valve gravity valve disc is arranged close to the one-way valve inlet flange. The one-way valve gravity valve disc opens in a direction toward the L-shaped pipeline.

[0009] The quick connector female head is provided with a quick connector plug, and the quick connector female head is connected to the quick connector plug through an iron chain.

[0010] The fixed flange is arranged above the quick-connect cargo hold input port at the other end of the L-shaped pipeline, near the bend of the L-shaped pipeline.

[0011] A gasket is provided between the fixed flange and the cargo hold hatch cover, and the gasket is a rubber gasket for increasing airtightness.

[0012] When in use, remove the quick connector plug, connect the quick connector female end to the quick connector male end of the delivery pipeline on the dock; insert the quick connector cargo hold input port into the reserved hole in the cargo hold, fix the fixed flange plate to the ship's cargo hold hatch cover with bolts, and place a rubber pad in the middle to increase the sealing. If there is a problem with the gravity check valve, it can be replaced as a whole by opening the check valve outlet flange plate and the check valve inlet flange plate, or it can be repaired by opening the check valve inspection port.

[0013] When loading cargo, the pressure on the inlet flange side of the one-way valve is greater than the pressure on the outlet flange side of the one-way valve, the gravity disc of the one-way valve is opened, and the cargo enters the cargo hold through the quick connector female head, connecting pipeline, gravity check valve, L-type pipeline and quick connector cargo hold input port in sequence. When loading is stopped, the pressure on the outlet flange side of the one-way valve is greater than the pressure on the inlet flange side of the one-way valve, the gravity disc of the one-way valve is closed under the action of gravity and the pressure side, and the cargo cannot flow back out of the cargo hold.

[0014] The beneficial effects of the utility model are: not only can it achieve efficient and firm connection with the cargo hold of the ship, but it can also prevent the slag powder from flowing back and leaking out due to the high pressure in the cargo hold when the loading vehicle is replaced or the pipeline is damaged, thereby protecting the ecological environment, ensuring the personal safety of workers, and improving work efficiency.

DETAILED DESCRIPTION

[0021] The present invention will be further described below through examples in conjunction with the accompanying drawings.

[0022] A pollution-proof quick connector for loading ships comprises a fixed flange 2, an L-shaped pipeline 3, a one-way valve outlet flange 4, a gravity one-way valve 5, a one-way valve inlet flange 6, a connecting pipeline 11 and a quick connector female head 7. Both ends of the gravity one-way valve 5 are respectively connected to the L-shaped pipeline 3 and one end of the connecting pipeline 11 through the one-way valve outlet flange 4 and the one-way valve inlet flange 6. A one-way valve inspection port 9 is provided above the gravity one-way valve 5. A quick connector cargo hold input port 1 is provided at the other end of the L-shaped pipeline 3. The quick connector cargo hold input port 1 is inserted into a cargo hold reserved hole of a cargo hold hatch cover and is connected to the cargo hold hatch cover through the fixed flange 2. A quick connector female head 7 is provided at the other end of the connecting pipeline 11, and the quick connector female head 7 is connected to a quick connector male head of a conveying pipeline.

[0023] The gravity check valve 5 is provided with a check valve gravity valve disc 10 , which is arranged close to the check valve inlet flange 6 , and the installation direction of the gravity check valve 5 is such that the check valve gravity valve disc 10 opens toward the L-shaped pipeline 3 side.

[0024] The quick connector female head 7 is provided with a quick connector plug 8 connected by a thin iron chain. The quick connector plug 8 is used for fixing the utility model to the cargo hold hatch cover of a ship to ensure the wind and rain tightness of the cargo hold structure when it is not connected to the loading pipeline.

[0025] The fixed flange 2 is arranged above the quick-connect cargo hold input port 1 at the other end of the L-shaped pipeline 3 and is arranged near the bend of the L-shaped pipeline 3 .

[0026] A gasket is provided between the fixed flange 2 and the cargo hold hatch cover, and the gasket is a rubber gasket for increasing airtightness.

[0027] When in use, remove the quick connector plug 8, and connect the quick connector female end 7 to the quick connector male end of the delivery pipeline on the dock; insert the quick connector cargo hold input port 1 into the reserved hole of the cargo hold, and fix the fixed flange 2 to the ship's cargo hold hatch cover with bolts, and place a rubber pad in the middle to increase the sealing. If there is a problem with the gravity check valve 5, it can be replaced as a whole by opening the check valve outlet flange 4 and the check valve inlet flange 6, or it can be repaired by opening the check valve inspection port 9.

[0028] When loading cargo, the pressure on the side of the one-way valve inlet flange 6 is greater than the pressure on the side of the one-way valve outlet flange 4, the one-way valve gravity valve disc 10 is opened, and the cargo enters the cargo hold through the quick connector female 7, the connecting pipe 11, the gravity one-way valve 5, the L-shaped pipe 3 and the quick connector cargo hold input port 1 in sequence. When loading is stopped, the pressure on the side of the one-way valve outlet flange 4 is greater than the pressure on the side of the one-way valve inlet flange 6, the one-way valve gravity valve disc 10 is closed under the action of gravity and the pressure side, and the cargo cannot flow back out of the cargo hold.

[0029] The other end of the L-shaped pipeline 3 of the utility model is directly inserted into the cargo ship hatch cover loading port (cargo hold reserved hole) and then connected to the cargo hold hatch cover through the upper fixed flange 2, and a gasket is used at the connection to increase the airtightness. The other end of the connecting pipeline 11 of the utility model is provided with a quick connector female head 7, which is quickly connected to the quick connector male head on the powder cargo delivery pipeline through the quick connector female head 7. When the powder cargo enters the ship cargo hold through the gravity check valve 5 under the action of the high-pressure air of the tank truck, when the loading is stopped or the pipeline is replaced, the pressure in the cabin is greater than the delivery pipeline, and the cargo in the cabin cannot flow back. In this way, the problem of slow fixing, unreliable connection, loose interface sealing, and cargo backflow in the cabin of the powder cargo loading pipeline is fundamentally solved. The utility model has two usage scenarios: (1) The utility model is permanently fixed on the hatch cover, and the input port at the other end of the connecting pipeline is blocked by a quick connector plug. When in use, simply remove the quick connector plug and quickly connect it to the delivery pipeline; (2) The utility model is stored on a ship or loading dock, and when in use, it is connected to the cargo hold reserved hole on the ship's cargo hold hatch cover through a fixed flange, and then connected to the tank truck delivery pipeline through a quick connector.

[0030] The application scenario of the utility model is a special connector for conveying pipelines and ship hatch covers for loading powdery goods. The technical problem to be solved by the utility model is: reducing the installation steps of loading pipelines, improving installation efficiency, and preventing slag powder from flowing back and leaking due to high pressure in the cargo hold when replacing loading vehicles, dismantling pipelines, or pipelines are damaged.

[0031] The utility model can be made into a standard powder cargo loading joint, and can standardize the loading joints of various docks with different shapes and rules. The utility model has a reasonable structural design, strong practicality, and can be mass-produced. The utility model can not only achieve efficient and firm connection with the cargo hold of the ship, but also prevent the slag powder from flowing back and leaking out due to the high pressure in the cargo hold when the loading vehicle is replaced or the pipeline is damaged, so as to protect the ecological environment, ensure the personal safety of workers, and improve work efficiency.
