[0015] The present invention also provides a method for using a marine methanol fuel supply boosting system, comprising the following steps:

[0016] S1, Medium pressurization:

[0017] The medium enters the filter box through the feed pipe, the first booster pump is started to pump the medium into the intermediate tank, and then the second booster pump is started to pump the medium into the pressure-stabilizing tank for use after pressurization.

[0026] S6, slag discharge:

[0027] When discharging slag, open the control valve, and the precipitated impurities are discharged through the slag discharge pipe, fall into the filter box, and enter the collection box through the discharge pipe.

[0028] The beneficial effects of the present invention are:

[0029] 1. The present invention discloses a marine methanol fuel supply and boosting system, which installs a safety component on one side of the intermediate tank and the pressure-surge tank, so that when the pressure in the intermediate tank and the pressure-surge tank is too high, the medium can enter the collection box through the drain pipe, thereby facilitating collection, avoiding leakage, and improving the safety of use;

[0031] 3. The present invention discloses a marine methanol fuel supply and pressurization system, which installs an exhaust pipe on the top of the intermediate tank, so that when the liquid level in the intermediate tank is reduced, the floating block is lowered, and the floating block drives the plug to move downward, thereby exhausting the air in the intermediate tank and avoiding the air being extracted for use;

[0032] 4.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0049] Example 1

[0050] like Figure 1-Figure 8 As shown, a marine methanol fuel supply boosting system includes a base 1, a top plate 2 is fixedly connected to the surface of the base 1, and a filter box 3 and an intermediate tank 6 are fixedly connected to the surface of the base 1. A feed pipe 8 for liquid inlet is arranged on one side of the filter box 3, so that the medium enters the filter box 3 through the feed pipe 8. Then, a first boosting pump 4 is fixedly connected to the surface of the top plate 2, and the liquid inlet end of the first boosting pump 4 is fixedly connected to the filter box 3, and the liquid outlet end of the first boosting pump 4 is fixedly connected to the intermediate tank 6 through a first connecting pipe 5, so that the medium is pumped into the intermediate tank 6 through the first boosting pump 4.

[0051] Subsequently, the second boosting pump 9 and the pressure stabilizing tank 11 are fixedly connected on the surface of the base 1, the liquid inlet end of the second boosting pump 9 is fixedly connected to the intermediate tank 6, and the liquid outlet end is fixedly connected to the pressure stabilizing tank 11 through the second connecting pipe 10, and a liquid outlet pipe 12 is installed on one side of the pressure stabilizing tank 11 so that the second boosting pump 9 can be started to pump the medium in the intermediate tank 6 into the pressure stabilizing tank 11, and the medium is discharged through the liquid outlet pipe 12 for use after being pressurized.

[0052] At the same time, the mounting pipe 13 is fixedly connected on one side of the intermediate tank 6 and the pressure-stabilizing tank 11, and a high-pressure protection safety component 14 is arranged at the other end of the mounting pipe 13. The safety component 14 includes a pressure-discharging pipe 40, which fixes and connects the pressure-discharging pipe 40 with the mounting pipe 13, and a drain pipe 45 is fixedly connected to the circumference of the pressure-discharging pipe 40. A rubber head 42 is slidably connected in the pressure-discharging pipe 40 so that it is located between the mounting pipe 13 and the drain pipe 45 for sealing the same. At the same time, an adjusting plate 43 is slidably connected in the pressure-discharging pipe 40, and a third spring 41 is fixedly connected between the adjusting plate 43 and the rubber head 42. In this way, when the pressure in the intermediate tank 6 or the pressure-stabilizing tank 11 is too high, the increased pressure will push open the rubber head 42, so that the medium can enter the collection box 7 through the drain pipe 45, thereby improving the safety of use and being able to collect the discharged medium to avoid leakage.

[0053] In addition, a threaded rod 44 is threadedly connected to one end of the pressure relief pipe 40 away from the mounting pipe 13, and the threaded rod 44 is rotatably connected to the adjustment plate 43. In this way, rotating the threaded rod 44 can adjust the position of the adjustment plate 43, thereby changing the pressure of the third spring 41 on the rubber head 42, making it more flexible to use.

[0054] Finally, a collection box 7 for collecting liquid is set at the bottom of the base 1, and the drainage pipe 45 is fixedly connected to the collection box 7. A discharge pipe is set on one side of the collection box 7, and a window is set to facilitate people's observation. At the same time, it can be used in conjunction with a liquid level meter and a water pump. When the liquid level is too high, the medium is discharged.

[0055] Example 2

[0056] Reference Figure 1-Figure 8 The present invention provides a new technical solution.

[0057] In the present invention, a filter screen 19 is slidably connected in the filter box 3, the filter screen 19 is tilted, and a plurality of tension springs 191 are fixedly connected between the bottom of the filter screen 19 and the inner wall of the filter box 3, so that the medium can be filtered through the filter screen 19.

[0058] In particular, a piston 31 is slidably connected inside the pressure-stabilizing tank 11, a slide rod 34 is fixedly connected to the top of the piston 31, the top of the slide rod 34 slides through the pressure-stabilizing tank 11, a second spring 33 is fixedly connected between the surface of the piston 31 and the top inner wall of the pressure-stabilizing tank 11, and a positioning ring 32 for limiting the piston 31 is fixedly connected to the circumferential inner wall of the pressure-stabilizing tank 11. When the medium pressure is unstable, the pressure is compensated to a certain extent through the up and down movement of the piston 31, thereby improving the stability of the output pressure.

[0059] It should be noted that one side of the filter box 3 is rotatably connected to a penetrating drive shaft 20, and the circumference of the drive shaft 20 is fixedly connected to at least two mounting rings 28, and the circumference of the mounting rings 28 is fixedly connected to wedge blocks 29, and the bottom of the filter screen 19 is fixedly connected to at least two vertical plates 30, which are used in conjunction with the wedge blocks 29. An overrunning clutch 21 is installed on the circumference of the drive shaft 20, and a rack 35 is fixedly connected to the surface of the piston 31, and the rack 35 is engaged with the overrunning clutch 21. During the up and down movement of the piston 31, the rack 35 can be driven to move, and the rack 35 drives the drive shaft 20 to rotate unidirectionally through the overrunning clutch 21. The drive shaft 20 drives the mounting ring 28 and the wedge blocks 29 to rotate, thereby shaking off the impurities filtered out from the bottom of the filter screen 19 to prevent affecting the operation of the filter screen 19.

[0060] In the present invention, a slag discharge pipe 22 is fixedly connected to one side of the bottom of the filter box 3, a control valve 23 is installed on the circumference of the slag discharge pipe 22, a slag collecting box 24 is fixedly connected to the surface of the base 1, the slag discharge pipe 22 is fixedly connected to the slag collecting box 24, a mounting plate 25 is fixedly connected to the top of the slag collecting box 24 by bolts, a filter box 26 is fixedly connected to the bottom of the mounting plate 25, the filter box 26 is located below the slag discharge pipe 22, a discharge pipe 27 is fixedly connected to the bottom of the slag collecting box 24, the other end of the discharge pipe 27 is fixedly connected to the collecting box 7, the control valve 23 is opened, the precipitated impurities are discharged through the slag discharge pipe 22, and then fall into the filter box 26 and enter the collecting box 7 through the discharge pipe 27.

[0061] In particular, a mounting seat 36 is fixedly connected to the inner wall of the top of the intermediate tank 6, a guide rod 37 is fixedly connected between the top and the bottom of the mounting seat 36, a floating block 38 is slidably connected to the circumference of the guide rod 37, a plug 39 is fixedly connected to the top of the floating block 38, and an exhaust pipe 18 is fixedly connected to the top of the intermediate tank 6, a valve is installed on the circumference of the exhaust pipe 18, and the top of the plug 39 is conical and is located in the exhaust pipe 18. When the liquid level in the intermediate tank 6 decreases, the floating block 38 drops, and the floating block 38 drives the plug 39 to move downward, thereby discharging the air in the intermediate tank 6 to prevent air from being extracted.

[0062] It should be noted that a plurality of semicircular flow stabilizers 15 are installed on the circumferential inner wall of the intermediate tank 6. The flow stabilizers 15 are staggered up and down, and the tops of the flow stabilizers 15 located at the top are provided with avoidance ports 16. When the medium is pumped into the intermediate tank 6, it is blocked by the plurality of flow stabilizers 15 to avoid large fluctuations of the medium in the intermediate tank 6.

[0063] In the present invention, a pressure gauge 17 is installed on the top of the intermediate tank 6 , and the pressure gauge 17 is convenient for people to observe the pressure of the intermediate tank 6 .

[0064] The advantages of the second embodiment over the first embodiment are:

[0065] 1. The filter 19 can be arranged to be movable, so that the filter 19 can be lifted up by the wedge block 29 and the vertical plate 30, and then fall down under the action of the tension spring 191, and then move to shake off the impurities filtered out at the bottom of the filter 19 to prevent affecting the operation of the filter 19;

[0066] Second, by installing the exhaust pipe 18 on the top of the intermediate tank 6, when the liquid level in the intermediate tank 6 is lowered, the floating block 38 is lowered, and the floating block 38 drives the plug 39 to move downward, thereby exhausting the air in the intermediate tank 6 to avoid air being extracted for use;

[0067] 3. By installing a filter box 26 on one side of the filter box 3, the control valve 23 is opened, and the precipitated impurities are discharged through the slag discharge pipe 22, then fall into the filter box 26, and enter the collection box 7 through the discharge pipe 27, which is convenient for people to handle.

[0068] The present invention also provides a method for using a marine methanol fuel supply boosting system, comprising the following steps:

[0069] S1, the medium enters the filter box 3 through the feed pipe 8, and then the first booster pump 4 is started to pump the medium into the intermediate tank 6, and then the second booster pump 9 is started to pump the medium in the intermediate tank 6 into the pressure-stabilizing tank 11, and then it is used after being pressurized;

[0070] S2. When the pressure in the intermediate tank 6 or the pressure-surge tank 11 is too high, the increased pressure pushes the rubber head 42 open, so that the medium can enter the collection box 7 through the drain pipe 45, thereby improving the safety of use and facilitating the collection of the discharged medium. When the threaded rod 44 is rotated, the threaded rod 44 can adjust the position of the adjustment plate 43, thereby changing the pressure of the third spring 41 on the rubber head 42;

[0071] S3. When the medium is pumped into the intermediate tank 6, it is blocked by multiple flow stabilizers 15 to prevent the medium from fluctuating greatly in the intermediate tank 6. At the same time, when there is a lot of air in the intermediate tank 6, the liquid level in the intermediate tank 6 is reduced, and then the floating block 38 is lowered, and the floating block 38 drives the plug 39 to move downward, thereby discharging the air in the intermediate tank 6 and preventing air from being extracted;

[0072] S4. When the medium passes through the pressure stabilizing tank 11, the pressure of the medium pushes the piston 31 upward. When the medium pressure is unstable, the pressure is compensated to a certain extent by the up and down movement of the piston 31, thereby improving the stability of the output pressure.

[0073] S5. When the medium passes through the filter box 3, it is filtered by the filter screen 19 in the filter box 3. During the process of the piston 31 moving up and down, the rack 35 can be driven to move. The rack 35 drives the drive shaft 20 to rotate unidirectionally through the overrunning clutch 21. The drive shaft 20 drives the mounting ring 28 and the wedge block 29 to rotate. The filter screen 19 is pushed up by the wedge block 29 and the vertical plate 30, and then falls down under the action of the tension spring 191, and then moves to shake off the impurities filtered out from the bottom of the filter screen 19 to prevent affecting the operation of the filter screen 19.

[0074] S6. When discharging slag, open the control valve 23, and the precipitated impurities are discharged through the slag discharge pipe 22, then fall into the filter box 26, and enter the collection box 7 through the discharge pipe 27.

[0075] However, as is well known to those skilled in the art, the working principles and wiring methods of the first boost pump 4 and the second boost pump 9 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
