DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0049] Example 1

[0050] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and provides an ultrasonic generator water treatment device, which includes a filter unit 1, including a filter housing 11, a filter member 12 arranged inside the filter housing 11, a sleeve rod 13 arranged at the bottom of the side wall of the filter housing 11, a sewage discharge member 14 arranged on the outside of the bottom of the sleeve rod 13, and a first elastic member 15 arranged on the outside of the sewage discharge member 14.

[0051] In this embodiment, the interior of the filter housing 11 is a hollow structure, and one end of the filter housing 11 is used to allow seawater to enter. Relatively clean seawater can be obtained after the seawater is filtered by the filter element 12 arranged inside the filter housing 11; the filter housing 11 mainly provides a relatively closed space for the filter element 12, so that the seawater entering the filter housing 11 can have a fixed flow direction.

[0052] Specifically, a receiving space O may be formed between the inner wall of one end of the filter housing 11 and the filter element 12 , so that the filtered impurities and microorganisms can be retained inside the receiving space O, and it is also more convenient to clean the impurities later.

[0053] It should be noted that the sleeve rod 13 is arranged inside the sewage pipe of the filter housing 11, and the sleeve rod 13 is a funnel-shaped structure with a large top opening and a small bottom opening; the larger top opening can better facilitate the collection of impurities, and the smaller bottom opening can quickly discharge impurities.

[0054] Preferably, the sewage discharge member 14 is sleeved on the outside of the bottom opening of the sleeve rod 13, and the bottom opening of the sleeve rod 13 can be closed by the sewage discharge member 14; the first elastic member 15 is connected to the sewage discharge member 14, and under normal conditions, the first elastic member 15 can push the sewage discharge member 14 to block the sleeve rod 13, thereby effectively preventing seawater from being discharged through the sewage discharge member 14 channel.

[0055] Furthermore, the cleaning unit 2 includes a connecting sleeve 21, a fixing sleeve 22 arranged inside the connecting sleeve 21, a blocking member 23 arranged at the end of the fixing sleeve 22, a trigger member 24 arranged on the outer wall of the connecting sleeve 21, a water tank 25 arranged at one end of the connecting sleeve 21, and a booster pump 26 arranged on the side wall of the water tank 25.

[0056] In this embodiment, the connecting sleeve 21 is connected to the filter housing 11, and the fixed sleeve 22 is fixed inside the connecting sleeve 21; and the sealing member 23 can be used to seal the fixed sleeve 22; under normal circumstances, the sealing member 23 is tightly attached to the end of the fixed sleeve 22, which can ensure the closure of the internal channel of the fixed sleeve 22.

[0057] It should be noted that the trigger member 24 is arranged at the end of the connecting sleeve 21, and the contact of the trigger member 24 penetrates into the inside of the connecting sleeve 21; the trigger member 24 is electrically connected to the boost pump 26, and when the fixing sleeve 22 and the blocking member 23 are in contact, the contact of the trigger member 24 is squeezed and controls the boost pump 26 to start, thereby achieving a certain linkage control.

[0058] Specifically, the water inlet of the water storage tank 25 is connected to the connecting sleeve 21, and the water outlet of the water storage tank 25 is connected to the booster pump 26 through a pipeline.

[0059] Preferably, the water outlet of the boost pump 26 is connected to the filter housing 11, and the pressurized water passing through the boost pump 26 can flow in the opposite direction of filtration, thereby achieving the effect of cleaning the filter element 12, further ensuring the water filtration property of the filter element 12, thereby maintaining the normal working efficiency of the filter.

[0060] When in use, seawater enters from the water inlet of the filter housing 11. Under the filtering action of the filter element 12, impurities and tiny organisms inside the seawater are isolated inside the solute space O, and the seawater passing through the filter element 12 is discharged through the drain port of the filter housing 11, wherein a portion of the filtered seawater enters into the water storage tank 25 through the connecting sleeve 21; when the water filtering holes of the filter element 12 are clogged by the accumulation of impurities, the pressure inside the filter housing 11 increases, and under the action of the pressure, a certain gap is opened between the sewage discharge element 14 and the sleeve rod 13, and then the impurities inside the solute space O are discharged together with the seawater; at this time, the seawater passes through the bottom of the filter housing 11. The seawater flows out of the drainage pipe, and the amount of seawater flowing to the side of the connecting sleeve 21 is reduced, and the pressure inside the connecting sleeve 21 is reduced, resulting in that the filtered seawater cannot flow into the inside of the connecting sleeve 21. At this time, the blocking member 23 conflicts with the fixed sleeve 22 under the elastic force of the reset member, and the blocking member 23 moves to contact the trigger member 24, so that the trigger member 24 controls the booster pump 26 to start, and the booster pump 26 transports the seawater inside the water storage tank 25 to the drainage end of the filter housing 11, and then makes the seawater flow in the reverse direction, so that the water filtering holes of the filter mesh member 12 can be cleaned; when the pressurized water flows into the solute space, the impurities can be discharged from the inside of the filter housing 11.

[0061] In summary, the set filtering unit can effectively filter out fine impurities and organisms inside the seawater, thereby effectively preventing foreign organisms from entering the ballast water; at the same time, the set cleaning unit can effectively clean the filtered impurities to ensure the water filtration performance of the filter, thereby ensuring the working efficiency of the ballast water treatment system.

[0062] Example 2

[0063] Reference Figure 1 to Figure 5, which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes, in the previous embodiment, the ultrasonic generator water treatment device includes, the filter housing 11 includes a sewage pipe 111 arranged on the side wall thereof, and an inlet end D1 and a drain end D2 with the same axis; the sewage pipe 111 is perpendicular to the axis of the inlet end D1; the filter element 12 includes a baffle 121 symmetrically arranged inside the filter housing 11, a filter membrane 122 arranged near the drain end D2, and a sand filter layer 123 arranged on one side of the filter membrane 122; the filter membrane 122 and the sand filter layer 123 are both located between the two groups of baffles 121; the position of the filter element 12 is staggered with the position of the sewage pipe 111.

[0064] In this embodiment, the water inlet end D1 and the water discharge end D2 of the filter housing 11 are arranged in the horizontal direction; and the sewage pipe 111 arranged outside the filter housing 11 and penetrating the interior thereof is perpendicular to the setting state of the filter housing 11; a sewage outlet along the horizontal direction is also opened on one side of the sewage pipe 111.

[0065] It should be noted that the filter element 12 includes two groups of symmetrically arranged baffles 121, and a certain filtering space U is formed inside the two groups of baffles 121; and the sand filter layer 123 on one side of the filtering space U close to the flow direction of seawater mainly plays a coarse filtering effect.

[0066] Preferably, the filter medium of the sand filter layer 123 can be quartz sand, gravel, etc., which can remove suspended particles and colloids in water through physical interception and adsorption.

[0067] Preferably, the filter membrane 122 is disposed on one side of the sand filter layer 123, mainly to filter the microorganisms and corpses remaining in the seawater.

[0068] Furthermore, the filter membrane 122 may be a microporous filter membrane, which is mainly made of polypropylene or polyethersulfone; it is mainly suitable for removing larger particles and bacterial corpses and improving the transparency of water quality.

[0069] The filter membrane 122 may also be an ultrafiltration membrane, which is mainly made of polysulfone and polyethersulfone; the microporous filter membrane is suitable for removing smaller particles and organic matter, further improving water quality.

[0070] Specifically, the position of the sewage pipe 111 is staggered with the position of the filter element 12 , so that the filtered impurities stay at one end of the filter element 12 close to the water inlet of the filter housing 11 , thereby effectively facilitating the discharge of the impurities through the sewage pipe 111 .

[0071] Furthermore, the drainage end D2 of the filter shell 11 is connected to the drainage pipe L1, and the side wall of the first drainage pipe L1 is connected to the diversion pipe L2; the filter shell 11 is connected to the connecting sleeve 21 through the diversion pipe L2; the other end of the connecting sleeve 21 is connected to the first delivery pipe S1; the connecting sleeve 21 is connected to the water tank 25 through the first delivery pipe S1.

[0072] In this embodiment, the other end of the drainage pipe L1 is connected to the ballast water system, and the filtered seawater enters the ballast water tank through the drainage pipe L1; the drainage pipe L1 is connected to the diversion pipe L2, and through the combination of the drainage pipe L1 and the diversion pipe L2, the filter housing 11 and the connecting sleeve 21 can be connected; and the other end of the connecting sleeve 21 is connected to the water storage tank 25 through the first delivery pipe S1.

[0073] Specifically, a connected loop can be formed through the pipeline, from the filter housing 11 to the drainage pipe L1, then from the drainage pipe L1 to the diversion pipe L2, and then the diversion pipe L2 flows to the inside of the connecting sleeve 21, and then enters the first delivery pipe S1 through the connecting sleeve 21, and finally enters the water storage tank 25 through the first delivery pipe S1.

[0074] Furthermore, a second delivery pipe S2 is installed at the water suction port of the boost pump 26, and a third delivery pipe S3 is installed at its water outlet; the water suction port of the boost pump 26 is connected to the water storage tank 25 through the second delivery pipe S2, and the water outlet of the boost pump 26 is connected to the filter housing 11 through the third delivery pipe S3; the water outlet end of the third delivery pipe S3 is located between the drainage end D2 of the filter housing 11 and the diversion pipe L2.

[0075] It should be noted that the water suction port of the boost pump 26 is connected to the water storage tank 25 through the second delivery pipe S2; the water outlet of the boost pump 26 is connected to the filter housing 11 through the third delivery pipe S3, and the connection position of the third delivery pipe S3 and the filter housing 11 is located between the drainage end D2 of the filter housing 11 and the diversion pipe L2, so that the pressurized seawater flowing out of the third delivery pipe S3 can flow from the drainage end D2 of the filter housing 11 to the water inlet end D1, thereby achieving the purpose of backwashing the water filtering holes of the filter mesh member 12.

[0076] Furthermore, the sleeve rod 13 is located inside the sewage pipe 111 ; the sewage discharge member 14 includes a sealing block 141 arranged at a central position inside the sleeve rod 13 , and a through hole 142 opened on a side wall thereof; the sealing block 141 can achieve blocking of the bottom of the sleeve rod 13 .

[0077] It should be noted that the sleeve rod 13 is arranged near the upper position of the sewage pipe 111, and a sewage discharge part 14 is arranged on the outer side of the bottom of the sleeve rod 13. The bottom of the sleeve rod 13 can be sealed by a sealing block 141, and 13 is in a sealed state, so that the seawater entering the filter housing 11 can flow along the direction from the water inlet end D1 to the discharge end D2.

[0078] Specifically, the sealing block 141 is made of rubber and has a truncated cone structure. The sealing block 141 penetrates into the interior of the sleeve rod 13, and the outer wall of the sealing block 141 can be tightly attached to the interior of the sleeve rod 13. Through the cooperation between the sealing block 141 and the sleeve rod 13, the bottom of the sleeve rod 13 can be sealed.

[0079] Preferably, a through hole 142 is provided on the outer wall of the sewage discharge member 14, and the position of the through hole 142 corresponds to the position of the sewage outlet provided on the side wall of the sewage pipe 111. After the impurities carried by seawater push the sleeve rod 13 and the sewage discharge member 14 to separate, the impurities carried by the seawater can pass through the through hole 142 and then be discharged from the interior of the filter housing 11 through the sewage outlet.

[0080] Furthermore, the first elastic member 15 is sleeved on the outside of the bottom of the sewage discharge member 14 ; the sewage discharge member 14 and the sewage discharge pipe 111 are linked via the first elastic member 15 ; the sewage discharge member 14 and the axis of the sleeve rod 13 coincide with each other.

[0081] It should be noted that the first elastic member 15 can be a device with a certain elastic potential energy, such as a spring or a metal spring. When the water pressure inside the filter housing 11 is in a normal state, the first elastic member 15 releases the elastic potential energy, so that the sewage discharge member 14 is in conflict with the bottom of the sleeve rod 13; when the water pressure inside the filter housing 11 is too high, the high pressure will push the first elastic member 15 to compress and store the elastic potential energy.

[0082] Furthermore, the trigger member 24 includes a touch-pressure switch 241 and a push rod 242 ; the touch-pressure switch 241 is electrically connected to the booster pump 26 ; the push rod 242 includes a contact 2421 and a reset member 2422 ; the contact 2421 penetrates into the interior of the connecting sleeve 21 .

[0083] It should be noted that the touch pressure switch 241 is an existing touch pressure switch, and the touch pressure switch 241 is electrically connected to the boost pump 26. When the contact of the touch pressure switch 241 is squeezed, the boost pump 26 can be controlled to start, thereby transporting the seawater inside the water tank 25 to the drainage end D2 side of the filter housing 11.

[0084] Specifically, the end of the contact 2421 protrudes into the interior of the connecting sleeve 21. Under normal conditions, the reset member 2422 releases elastic potential energy to push the end of the push rod 242 away from the contact of the touch-pressure switch 241, thereby ensuring that the booster pump 26 does not work under normal conditions.

[0085] Furthermore, the blocking member 23 includes a second elastic member 231 disposed on the outside of the rod portion, and a protrusion 232 disposed on its side wall; the protrusion 232 can abut against the contact 2421 , thereby enabling the push rod 242 to squeeze the contact of the touch switch 241 .

[0086] It should be noted that, under normal conditions, the second elastic member 231 can push the blocking member 23 to contact the end of the fixed sleeve 22, and the fixed sleeve 22 and the blocking member 23 are arranged in the horizontal direction; when seawater enters the connecting sleeve 21 from the diversion pipe L2, the second elastic member 231 is compressed, and a certain gap is opened between the blocking member 23 and the fixed sleeve 22, so that seawater can enter the first conveying pipe S1 through the connecting sleeve 21. When the connecting sleeve 21 is filled with seawater, the pressure on the left and right sides of the blocking member 23 is in a relatively balanced state. At this time, the blocking member 23 and the fixed sleeve 22 remain in an open state.

[0087] Specifically, the protrusion 232 is a trapezoidal structure. When the sealing member 23 contacts the end of the fixing sleeve 22, the end of the protrusion 232 can contact the contact 2421 and can push the push rod 242 to contact the contact of the touch switch 241, thereby controlling the boost pump 26 to be in the on state.

[0088] Furthermore, a first one-way valve H1 is installed inside the third delivery pipeline S3, and the first one-way valve H1 is for one-way flow from the booster pump 26 to the filter housing 11; a second one-way valve H2 is installed inside the diversion pipeline L2, and the second one-way valve H2 is for one-way flow from the connecting sleeve 21 to the water tank 25.

[0089] When in use, seawater enters the filter housing 11 through the water inlet end D1 of the filter housing 11, and then is discharged through the drain end D2 of the filter housing 11 after being filtered by the filter mesh 12; the filtered seawater enters a part of the drain pipe L1, and enters the ballast water tank through the drain pipe L1; the other part enters the connecting sleeve 21 through the diversion pipe L2, and the seawater pushes the sealing member 23, so that the second elastic member 231 is in a compressed energy storage state; at this time, the sealing member 23 and the fixing sleeve 22 are opened, so that seawater flows into the first delivery pipe S1 through the connecting sleeve 21, and then gathers in the water storage tank 25; when the water storage tank 25 is filled with seawater, a certain liquid balance is formed inside the connecting sleeve 21, and the sealing member 23 and the fixing sleeve 22 are in a normally open state; at this time, the filtered seawater flowing out from the drain end D2 of the filter housing 11 enters the ballast water tank.

[0090] During the filtering process of the filter element 12, its filter holes are clogged by impurities and tiny organisms, which will cause the filterability of the filter element 12 to decrease; at this time, seawater continuously enters the filter housing 11, which increases the pressure at the water inlet end D1 of the filter housing 11, and the high-pressure seawater pushes the sewage discharge member 14 to move, so that the sealing block 141 and the sleeve rod 13 are separated. At this time, the first elastic member 15 is in a compressed energy storage state; then the seawater carries the impurities deposited in the solute space O of the filter housing 11 through the through hole 142 to the sewage outlet, and then is discharged from the filter housing 11; when the sewage discharge member 14 and the sleeve rod 13 are in the open state, most of the seawater is discharged through the sewage pipe 111, and the inlet As a result, the water flow and pressure inside the drainage end D2 of the filter housing 11 are reduced, so that the filtered seawater does not enter the diversion pipe L2 at a sufficient pressure, and the seawater inside the diversion pipe L2 flows back to the drainage pipe L1 under the action of gravity; since the first delivery pipe S1 is provided with a first one-way valve H1, the seawater inside the water tank 25 will not flow in the opposite direction; at this time, the second elastic member 231 releases its elastic potential energy and pushes the blocking member 23 and the fixing sleeve 22 to conflict with each other, and the movement of the blocking member 23 drives the protrusion 232 to conflict with the contact 2421; the push rod 242 contacts the contact of the touch-pressure switch 241 and controls the start of the boost pump 26.

[0091] The filtered seawater in the water tank 25 is then pressurized by the booster pump 26 and transported to the drain end D2 of the filter housing 11; the pressurized seawater then flows in the direction from the drain end D2 to the water inlet end D1; thereby, the purpose of backwashing the filter element 12 can be achieved. During the backwashing process, the impurities flushed from the inside of the water filter holes can be discharged from the inside of the filter housing 11 along the sewage pipe 111, thereby ensuring the filtering effect of the filter element 12.

[0092] When the pressure inside the water inlet end D1 of the filter housing 11 is restored to the away state, the first elastic member 15 releases the elastic potential energy to push the sewage discharge member 14 to contact the bottom of the sleeve rod 13, and the channel inside the sewage discharge pipe 111 is blocked; at this time, the seawater enters the filter housing 11 and is normally filtered by the filter mesh member 12; and the booster pump 26 extracts a part of the water inside the water storage tank 25, so that the inside of the water storage tank 25 is in a negative pressure state, thereby separating the protrusion 232 and the contact 2421, and then stopping the booster pump 26; and then allowing the seawater to enter the connecting sleeve 21 again through the diversion pipe L2, and then flow into the water storage tank 25, thereby ensuring that the blocking member 23 and the fixing sleeve 22 are in a normally open state.

[0093] Example 3

[0094] Reference Figure 1-2, which is the third embodiment of the present invention, and is different from the previous two embodiments in that: it includes a water treatment unit 3, including an ultrasonic generator 31, an ultrasonic unit 32 arranged on the top of the ultrasonic generator 31, and a cleaning box 33 that conflicts with the output end of the ultrasonic unit 32; the water treatment unit 3 is integrated inside the ballast water treatment unit M; the water outlet of the cleaning box 33 is connected to the filter housing 11.

[0095] It should be noted that the ultrasonic generator 31 is responsible for generating high-frequency electrical signals to drive the ultrasonic unit 32 to work.

[0096] The ultrasonic unit 32 is disposed on the top of the ultrasonic generator 31 , receives the electrical signal from the ultrasonic generator 31 and converts it into mechanical vibration to generate ultrasonic waves.

[0097] The cleaning box 33 is located below the output end of the ultrasonic unit 32 and is in close contact with the ultrasonic unit 32. Through the mechanical vibration of the ultrasonic wave, the organisms and impurities in the water are effectively removed. The water outlet of the cleaning box 33 is connected to the filter housing 11 to ensure that the treated water flows smoothly into the filter housing 11 for further filtration.

[0098] It should be noted that the ultrasonic generator 31 is a relatively mature device. Its principle is to use ultrasonic technology to effectively kill or inhibit the growth of microorganisms. Its mechanism includes pressure effect, shear force effect and cavitation effect. The pressure fluctuation of ultrasonic waves destroys the cell wall of microorganisms, the shear force affects the cell membrane, and the cavitation phenomenon generates shock waves and high temperature through the bursting of bubbles, thereby effectively killing bacteria and other tiny microorganisms in seawater.

[0100] Specifically, the water treatment unit 3 is integrated into the ballast water treatment unit M, adopting a compact spatial layout. The integrated design allows the various components to be closely arranged, reducing the volume of the overall equipment and saving valuable space on the ship; this is especially important for ships with limited space.

[0101] At the same time, efficient energy transfer is maintained, and the distance between the ultrasonic generator 31, the ultrasonic unit 32 and the cleaning box 33 is shortened, ensuring efficient energy transfer and utilization; the high-frequency electrical signal generated by the ultrasonic generator can directly drive the ultrasonic unit to reduce energy loss.

[0102] Further simplifying installation and maintenance, the integrated design makes the installation process easier and reduces the workload of on-site assembly. At the same time, maintenance and repair are also more convenient, and technicians can operate in a centralized area, improving work efficiency.

[0103] The system coordination is better enhanced, and the various components work more closely together, ensuring the stability and reliability of the entire ballast water treatment system; the water after ultrasonic treatment can directly flow into the filter housing 11, realizing a continuous treatment process and improving the treatment efficiency.
