Description

Technical Field

[0001] The present invention relates to the field of shipbuilding, and in particular to a liquid extraction device and method. Background Art

[0002] During the process of ship manufacturing and installation, it is often necessary to use airbags and other equipment to extract liquids from the ship. Currently, the airbags used for liquid extraction on the market are generally of two types: 4-point and 6-point. In actual work, the speed of liquid extraction cannot be increased due to the constraints of the pipe diameter. If multiple airbags are used side by side for simultaneous extraction, there is a phenomenon that the pipe diameter does not match and multiple airbags cannot be inserted. At the same time, due to the self-rebound characteristics of the airbag, there is also a phenomenon of insufficient suction when extracting liquids with high viscosity.

[0003] Therefore, how to use multiple air bags to effectively increase the speed of liquid extraction and avoid insufficient suction when extracting liquids with high viscosity has become an urgent problem to be solved. Summary of the invention

[0004] In order to use multiple air bags to increase the speed of liquid extraction, the present invention provides a liquid extraction device and method. The method closes the stop valve and squeezes the air bag to fill water into the main pipe of the device, opens the stop valve after it is filled, and realizes rapid extraction of liquid through the siphon principle, thereby solving the current technical problem of insufficient suction when extracting liquids with high viscosity.

[0005] The solution adopted by the present invention to solve the technical problem is: A liquid extraction device comprises a stop valve for intercepting the sucked liquid; a diverter comprising a main pipe and a plurality of branch pipes, wherein the main pipe is assembled at the upper end of the stop valve; a combiner comprising a main pipe and a plurality of branch pipes, wherein the main pipe is assembled at the lower end of the stop valve; an air bag correspondingly assembled at the lower end of each branch pipe of the diverter; and a plurality of branch pipes, wherein one end of the branch pipes is assembled at the lower end of the air bag and the other end is assembled at the upper end of each branch pipe of the combiner.

[0006] The embodiment disclosed herein uses standard parts for the shut-off valve and the airbag, and the diverter and the combiner are symmetrically installed and used with the same specifications. The branch pipes of the diverter and the combiner are horizontally or circumferentially distributed, and the number of the branch pipes is two or four.

[0007] In order to further solve the technical problem to be solved by the present invention, the present invention provides a method for using a liquid extraction device, comprising the following steps: Step 1. Determine that the main pipe diameter D of the flow divider and the flow combiner is the maximum pipe diameter of the device, and the port pipe diameter of the airbag is a fixed value d; Step 2. Calculate the number S of the airbags according to the size of D. Since the sum of the cross-sectional areas of the port diameters of the airbags is greater than the main pipe diameter D of the diverter, it is concluded that d²S>D², and furthermore, S>D² / d². Considering the loss of liquid in the device, the number S of the airbags in actual work is greater than 1.5×D² / d². Step 3. Make the flow divider and the flow combiner of corresponding specifications, and assemble them with the corresponding number of air bags and the multi-section branch pipes; Step 4. close the stop valve, squeeze each of the air bags, suck out the liquid and store it in the upper end tube of the stop valve; Step 5. When the liquid flows out from the upper end of the diverter, slowly open the stop valve, use the liquid stored in the upper end of the stop valve to form a siphon phenomenon, and continuously suck out the liquid.

[0008] Positive effects: The present invention assembles a flow divider at the upper end of the stop valve, assembles a combiner at the lower end, assembles an air bag at the lower end of each branch pipe of the flow divider, assembles a multi-section branch pipe at the lower end of the air bag, and the other end of the multi-section branch pipe is assembled at the upper end of each branch pipe of the combiner. After closing the stop valve, squeeze the air bag to inject water into the main pipe of the device, open the stop valve after it is filled, and realize rapid extraction of liquid through the siphon principle. The device is simple and convenient to operate, easy to disassemble and maintain, effectively saves costs and reduces the labor intensity of workers. It is suitable for use as a liquid extraction device and method. BRIEF DESCRIPTION OF THE DRAWINGS
