Description

Technical Field

[0001] This utility model relates to the technical field of liquid inlet and return devices, and in particular to a marine deck integrated liquid inlet and return device. Background Technology

[0002] A liquid inlet and outlet system is an integrated device for liquid transport and circulation. Its core function is to achieve "two-way flow management" of liquids—it is responsible for transporting liquids, such as oil, water, coolant, and chemicals, from the source to the target system, and it can also return excess, circulated, or reclaimed liquids from the system to the source or treatment device, forming a closed-loop liquid circulation system. Through pump sets, pipelines, and control valves, it transports liquids from storage devices, such as storage tanks and containers, to where they are needed, such as mechanical components, reaction vessels, and ship storage tanks, ensuring that the target system receives a sufficient supply of liquids.

[0003] The existing inlet and outlet water pipes are all welded carbon steel pipes with a split design. They are fixed by welding multiple brackets onto the pipe body. The problem is that the pipe body has low dimensional accuracy, which makes it difficult for the bracket holes to fit and be aligned.

[0004] An existing patent (publication number: CN203892721U) discloses an integrated high-hydraulic forming hydraulic retarder inlet and outlet water pipe, which includes a return water pipe and an inlet water pipe of the hydraulic retarder. An integral double-hole flange fixes one end of the return water pipe and the inlet water pipe side by side. A first movable clamp is provided in the middle of the return water pipe and the inlet water pipe to fix the return water pipe and the inlet water pipe together side by side. The first movable clamp has a first mounting ear with a mounting hole. The side of the return water pipe that is in contact with the inlet water pipe has a corresponding return water pipe boss and an inlet water pipe boss. It integrates the inlet and return water pipes into one design and uses a high-hydraulic forming pipe body, which improves strength, avoids resonance, and facilitates assembly, disassembly and maintenance.

[0005] To address the aforementioned issues, while existing patents have proposed integrated inlet and outlet pipe designs and high-hydraulic forming pipe bodies that improve strength, prevent resonance, and facilitate assembly, disassembly, and maintenance, they do not allow for the recycling of excess liquid during transport, resulting in some liquid waste and poor practicality. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated liquid inlet and return device for marine decks. High-pressure liquid enters the return component through a connecting pipe, pushing a movable block to move. The liquid flows through the through holes inside the first and second fixed components, then flows back into the filling pipe through the return pipe, and finally into the storage tank for recovery. During the self-reset process of the compression spring, the movable block is pushed to reset, thus achieving unidirectional liquid recovery. Furthermore, this device achieves integrated liquid inlet and liquid recovery, improving practicality and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a marine deck integrated liquid inlet and return device, including a liquid storage tank, a liquid filling pipe connected to the upper surface of the liquid storage tank, a recovery mechanism for liquid recovery provided on the right side of the liquid storage tank, and a filtration mechanism for liquid filtration provided on the outer wall of the recovery mechanism.

[0008] The recycling mechanism includes a conveying pipe connected to the right side of the storage tank. A connecting pipe is connected to the outer wall of the end of the conveying pipe, and a return component is connected to the end of the connecting pipe. A first fixing component is fixed to the inner wall of the return component, and two guide rods are fixed to the side wall of the first fixing component. Movable blocks are slidably connected to the outer surfaces of the two guide rods.

[0009] Preferably, the ends of both guide rods are fixed with a second fixing member that is fixedly connected to the inner wall of the return component, and the outer walls of both guide rods are fitted with a compression spring that abuts against the second fixing member.

[0010] Preferably, one end of the reflux member is connected to a reflux pipe that is interconnected with the liquid addition pipe, and the upper end of the liquid storage tank is connected to a pressure relief valve.

[0011] Preferably, a sewage valve is installed on one side of the delivery pipe, a manual valve is fixed on the outer surface of the liquid addition pipe, and several reinforcing rods are fixed at equal intervals at both the upper and lower ends inside the liquid storage tank.

[0012] Preferably, the filtration mechanism includes a filter connected to one side of the delivery pipe, and a filter screen is fixed inside the filter by screws.

[0013] Preferably, the lower surface of the filter is connected to a cleaning tube, and one end of the cleaning tube is threadedly connected to a sealing cap.

[0014] Preferably, a delivery pump is connected to one side of the filter, and pressure gauges are installed at both the input and output ends of the delivery pump.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the set recovery mechanism, the high-pressure liquid enters the return component through the connecting pipe. The liquid pushes the movable block to move, and the liquid flows through the through holes inside the first and second fixed components. It then flows back into the liquid filling pipe through the return pipe and enters the liquid storage tank for recovery. During the process of the compression spring resetting itself, it pushes the movable block to reset, thereby realizing the function of one-way liquid recovery. In addition, the device realizes the functions of integrated liquid inlet and liquid recovery, improving practicality.

[0017] 2. The filter mechanism and filter screen can filter impurities in the liquid. The filtered liquid is then discharged through the delivery pipe for use. During subsequent maintenance, the sealing cap can be unscrewed through the cleaning pipe on the filter, and the side wall of the filter screen can be cleaned through the cleaning pipe, thereby effectively reducing the possibility of the filter screen becoming clogged.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4A marine deck integrated liquid inlet and return device includes a liquid storage tank 1, a liquid filling pipe 2 connected to the upper surface of the liquid storage tank 1, a recovery mechanism for liquid recovery on the right side of the liquid storage tank 1, and a filtration mechanism for liquid filtration on the outer wall of the recovery mechanism.

[0028] The recycling mechanism includes a conveying pipe 3, which is connected to the right side of the storage tank 1. The outer wall of the end of the conveying pipe 3 is connected to a connecting pipe 31, and the end of the connecting pipe 31 is connected to a return component 32. The inner wall of the return component 32 is fixed with a first fixing component 33. The side wall of the first fixing component 33 is fixed with two guide rods 34. The outer surfaces of the two guide rods 34 are slidably connected with movable blocks 36. The ends of the two guide rods 34 are fixed with second fixing components 35 that are fixedly connected to the inner wall of the return component 32. The outer walls of the two guide rods 34 are fitted with compression springs 37 that abut against the second fixing components 35. One end of the return component 32 is connected to a return pipe 38 that is connected to the liquid filling pipe 2. The upper end of the storage tank 1 is connected to a pressure relief valve 4. A sewage valve 5 is installed on one side of the conveying pipe 3. A manual valve 7 is fixed on the outer surface of the liquid filling pipe 2. Several reinforcing rods 8 are fixed at equal intervals at both the upper and lower ends inside the storage tank 1.

[0029] By adopting the above technical solution, the storage tank 1 is placed in a suitable position. Liquid can be added to the storage tank 1 by opening the manual valve 7 on the filling pipe 2. The pressure relief valve 4 on the storage tank 1 allows gas inside to be normally discharged to the outside. Furthermore, the reinforcing rod 8 inside the storage tank 1 enhances the strength of the shell, thereby improving its service life. During use, the liquid in the storage tank 1 can be drawn out by the delivery pump 64 on the delivery pipe 3. When the pressure of the liquid during delivery through the delivery pipe 3 becomes excessive, the liquid with higher pressure enters the return component 32 through the connecting pipe 31. Through the first fixing member 33 inside the return component 32, the liquid with higher pressure pushes the movable block 36 to move. At this time, the movable block 36 separates from the side wall of the first fixing member 33, releasing the flow restriction on the first fixing member 33. The liquid then flows through the through holes inside the first fixing member 33 and the second fixing member 35, flows back into the filling pipe 2 through the return pipe 38, and then enters the storage tank 1 for recycling. When the liquid pressure returns to normal, the compression spring 37 will push the movable block 36 to reset during its self-reset process, causing the movable block 36 to contact the side wall of the first fixed member 33, thus limiting the flow of the first fixed member 33. The guide rod 34 guides the movable block 36, thereby achieving unidirectional liquid recovery. This device integrates liquid inlet and liquid recovery, improving practicality. Wastewater from the storage tank 1 can be discharged through the wastewater valve 5 after cleaning, facilitating use.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the filtration mechanism includes a filter 6, which is connected to one side of the delivery pipe 3. A filter screen 61 is fixed inside the filter 6 by screws. A cleaning pipe 62 is connected to the lower surface of the filter 6. A sealing cap 63 is threaded to one end of the cleaning pipe 62. A delivery pump 64 is connected to one side of the filter 6. Pressure gauges 65 are installed at both the input and output ends of the delivery pump 64.

[0031] By adopting the above technical solution, when the liquid passes through the filter 6, the filter screen 61 can filter impurities in the liquid, and the filtered liquid is then discharged through the delivery pipe 3 for use. During subsequent maintenance, the sealing cap 63 can be unscrewed through the cleaning pipe 62 on the filter 6, and the side wall of the filter screen 61 can be cleaned through the cleaning pipe 62, thereby effectively reducing the possibility of clogging of the filter screen 61 and facilitating its use. Pressure gauges 65 installed at the input and output ends of the delivery pump 64 can detect the liquid pressure.

[0032] Working principle: The liquid in the storage tank 1 is drawn out by the pump 64 installed on the delivery pipe 3. When the liquid passes through the filter 6, the filter screen 61 filters out impurities in the liquid. The filtered liquid is then discharged through the delivery pipe 3 for use. During subsequent maintenance, the sealing cap 63 can be unscrewed through the cleaning pipe 62 installed on the filter 6, and the side wall of the filter screen 61 can be cleaned through the cleaning pipe 62, effectively reducing the possibility of clogging and facilitating use. Pressure gauges 65 installed at the input and output ends of the pump 64 can detect the liquid pressure. When excessive pressure occurs during liquid delivery through the conveying pipe 3, the pressurized liquid enters the return component 32 through the connecting pipe 31. Passing through the first fixed component 33 within the return component 32, the pressurized liquid pushes the movable block 36 to move. At this point, the movable block 36 separates from the side wall of the first fixed component 33, releasing the flow restriction on the first fixed component 33. The liquid then flows through the through holes inside the first fixed component 33 and the second fixed component 35, flows back into the filling pipe 2 through the return pipe 38, and then enters the storage tank 1 for recovery. When the liquid pressure returns to normal, the compression spring 37 resets itself, pushing the movable block 36 back to its original position. This causes the movable block 36 to contact the side wall of the first fixed component 33, restricting the flow. The guide rod 34 guides the movable block 36, thus achieving unidirectional liquid recovery. This device achieves integrated liquid inlet and liquid recovery. Through the wastewater valve 5, the cleaned wastewater in the storage tank 1 can be discharged.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
