Description

TECHNICAL FIELD

[0001] The present application relates to the field of separation equipment, in particular to a ship ballast water sediment receiving and disposing device. BACKGROUND

[0002] Ballast water is water added to a specific ballast tank for the purpose of adjusting the stability, draft, hull balance and other navigation performance of a ship, and the ballast water usually contains a large amount of marine organisms, suspended silt and solid particles, which need to be separated and treated before being discharged into the sea.

[0003] In some existing ships, a separation and treatment system is provided to separate and treat the ballast water, such as a backwashing filter, but marine organisms are diverse, and are affected by seawater, sand, marine organisms and other conditions during separation and treatment, such as marine organisms such as shellfish and sea squirt larvae, which will still stubbornly remain on the filter structure during backwashing without the basis of external vibration force, making the separation and treatment equipment less effective, and the system carried on the ship is easily out of the applicable range under environmental conditions such as sea conditions and water quality, performance fluctuation occurs, faults occur, and the separation and treatment efficiency is prone to decay, which cannot achieve the expected effect when the system is used alone, so the demand for separate ballast water separation and treatment systems outside the ship is gradually increasing in the application market.

[0008] Furthermore, a laterally extending connecting beam is fixed to the bottom end of the collecting rod, and the top end of the movable column is detachably fixed to the end of the connecting beam. The top end of the array of the fixed ring and the movable bar is spaced apart from the top cover. The top spring is nested between the connecting beam and the top cover and is located outside the main column. The top spring provides downward elastic force to the collecting rod, the connecting beam, and the movable column. The top spring forms a second filter grid structure. The top spring is a spring and its coil diameter is equal to the diameter of the fixed ring and the movable bar. The coil gap of the top spring that drives the movable column downward to the limit of the movable column's stroke is equal to the gap between the fixed ring and the movable bar.

[0009] Furthermore, several main columns are fixed with annular column connecting rings at their bottom ends. The column connecting rings are fixedly connected to the base. A limiting seat is provided on the bottom column connecting rings. A through hole is opened in the middle of the limiting seat. A guide shaft is fixed to the bottom end of the movable column. The guide shaft is slidably nested on the limiting seat. The movable column driven downward by the top spring force abuts against the limiting seat.

The subsequent-stage separation device is used to centrifuge the solids separated by the receiving and separating device. A buffer chamber is also connected between the receiving and separating device and the end-of-line discharge device. The end-of-line discharge device is used to process and discharge the liquids separated by the receiving and separating device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes a separation device and its supporting equipment installed within a container, operating independently of the ship. This eliminates concerns about ship operation or marine environmental factors. The separation device comprises a fixed ring and a movable strip. A top spring keeps the movable strip in its normal position, forming a filter grid structure with the top spring, movable strip, and fixed ring. A top vibration mechanism drives a collecting rod connected to the movable strip upwards, compressing the top spring and causing the movable strip to swing upwards and rub against the fixed ring. This generates small vibrations and increases the flow velocity in the local gaps. Furthermore, the top vibration mechanism creates intermittent lifting and high-drop phases, causing the movable column connected to the movable strip below the collecting rod to impact the base. This generates a large vibration across the entire filter mechanism, including the movable strip and fixed ring, resulting in better vibration and shaking effects, facilitating the removal of adsorbent organisms.

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Examples, such as Figures 1-16As shown: This invention provides a ship ballast water sediment receiving and treatment device, comprising a housing 3 and a control cabinet 4, and a receiving and separating device 1 fixedly installed in the housing 3. A buffer tank 2 and a terminal discharge device 5 are connected to the receiving and separating device 1 via a pipe 6. In this embodiment, the receiving and separating device 1 is also connected to a downstream separation device via a pipe 6. The control cabinet 4 connects to the electrical control components of each device to control them. The housing 3 is a container 3, in which each device is skid-mounted for easy movement to the port for external separation treatment of ship ballast water. The receiving and separating device 1 is a backwash filter, connected to the ship's ballast water receiving interface, automatically filtering large particles, marine organisms, etc., from the ballast water. The receiving and separating device 1 has an automatic backwashing function, which can self-clean without stopping the machine. After filtration and separation, solids and liquids are produced. The subsequent separation device is used to centrifuge the solids separated by the receiving and separating device 1. Since the separated solids are carried out by backwashing, they contain some moisture. The filter material and sediment processed by centrifugation have low water content, which is more conducive to subsequent transportation and treatment. A buffer tank 2 is also connected between the receiving and separating device 1 and the terminal discharge device 5 to hold the liquids. The terminal discharge device 5 is used to treat and discharge the liquids separated by the receiving and separating device 1. In this embodiment, the terminal discharge device 5 adopts an ultraviolet sterilization device. It receives the liquids after ballast water filtration and sterilizes and inactivates them with a high-intensity ultraviolet lamp group before discharge.

[0039] The receiving and separating device 1 includes a tank structure, which comprises, from bottom to top, an inlet tank 13, a bottom partition 12, a main tank 11, a top partition 14, and a top tank 15. The inlet tank 13, the main tank 11, and the top tank 15 are detachably fixed together by bolts. The top partition 14 is sandwiched between the main tank 11 and the top tank 15, and the bottom partition 12 is sandwiched between the main tank 11 and the inlet tank 13. An inlet pipe 101 is provided on the side of the inlet tank 13, and an outlet pipe 102 is provided on the side of the main tank 11. The main tank 11 contains the top partition... Several filter mechanisms 16 are nested between plate 14 and bottom partition 12. The bottom partition 12 has an exchange port 121. The filter mechanism 16 has a cavity inside and is connected to the water inlet tank 13 through the exchange port 121. Water flows into the tank structure through the water inlet tank 13 and then upward into the filter mechanism 16. The ballast water is intercepted and separated by the filter mechanism 16, so that solids remain in the filter mechanism 16, while water passes through the filter mechanism 16 into the main tank 11 and is discharged into the next device through the water outlet pipe 102.

[0040] Meanwhile, a backflushing mechanism 17 is installed throughout the tank structure. The backflushing mechanism 17 includes a rotating shaft 171 and a backflushing pipe 172. The rotating shaft 171 extends downward from the top tank 15 through the main tank 11 into the inlet tank 13. The top of the rotating shaft 171 extends out of the top tank 15 and is connected to a backflushing motor 18. The backflushing pipe 172 is fixed to the bottom end of the rotating shaft 171 inside the inlet tank 13 and has a receiving pipe 173 extending laterally. The bottom end of the inlet tank 13 is fixed to a discharge pipe 103. The backflushing pipe 172 is sealed and nested within the discharge pipe 103. The receiving pipe 173 is connected to the discharge pipe 103. The backflushing pipe 172 retains the freedom to rotate around the axis of the rotating shaft 171 on the discharge pipe 103. That is, the rotating shaft 171 can drive the backflushing pipe 172 to rotate on the discharge pipe 103. The receiving pipe 173 extends laterally and is bent upward. The top of the upward bend of the receiving pipe 173 is provided with the receiving head 174 in the prior art, that is, a connector that is continuously pushed against the bottom partition plate 12 by an elastic element to ensure communication with the AC port 121.

[0041] Furthermore, the filtration mechanism 16 comprises three parts: a basic frame, a filtration area, and a vibration generation part.

[0042] For the basic frame part, the basic frame part of the filter mechanism 16 includes a base 161, a top cover 162 and several main columns 163 fixedly installed between the base 161 and the top cover 162. The base 161 has an opening at the bottom and is engaged with the communication port 121. The top and bottom ends of the several main columns 163 are fixed with annular column connecting rings 1631. The column connecting rings 1631 at both ends are detachably fixed to the top cover 162 and the base 161, such as by bolt fixing. In this embodiment, three main columns 163 are used.

[0043] For the filtration area, the main column 163 has spaced fixed rings 164 engaged vertically. An outer cover plate 1632 is provided on the main column 163 and is bolted to the outside of the main column 163. The fixed rings 164 are clamped and fixed between the main column 163 and the outer cover plate 1632. Movable strips 166 are nested horizontally within the main column 163. The movable strips 166 are vertically positioned between the fixed rings 164 and cooperate with the fixed rings 164 to form evenly spaced intervals. The fixed rings 164 are annular. The movable strips 166 include an extended section 1661 and side shaft sections 16 on both sides. 62. The extended section 1661 is arc-shaped and has the same diameter as the fixed ring 164. The side shaft section 1662 is convex. The main column 163 has a recessed movable side groove 1634 on its side. The inner side of the main column 163 is fixed with an inner cover plate 1633 by bolts. The side shaft section 1662 is embedded and engaged in the movable side groove 1634 and is covered and fixed by the inner cover plate 1633. The movable bar 166 has space to swing with the side shaft sections 1662 on both sides as fulcrums. The movable bars 166 between adjacent main columns 163 are connected by vertical movable columns 165. In this embodiment, three movable columns 165 are used.

[0044] It should be noted that the distance from the axis of the side shaft segment 1662 to the center of the extended segment 1661 is less than the radius of the extended segment 1661. That is, the side shaft segment 1662 is closer to the center of the extended segment 1661 than the extended segment 1661, which makes the swing point of the movable bar 166 closer to the inward side. The distance between the side shaft segment 1662 and the extended segment 1661 is less than the distance between the side shaft segment 1662 and the adjacent fixed ring 164. Since the side shaft segment 1662 is at the edge of the movable bar 166, it is difficult for elastic deformation to reduce the distance between the side shaft segment 1662 and the extended segment 1661 to occur. Therefore, the distance between the equilateral shaft segment 1662 and the adjacent fixed ring 164 is set in advance to avoid the connection between the side shaft segment 1662 and the extended segment 1661 and the fixed ring 164 becoming too tight and jamming during the upward swing of the movable bar 166.

[0045] Simultaneously, the fixed ring 164 and the movable strip 166 form a first filter grid structure. The movable strip 166 also includes an inner lifting section 1663 located in the middle of the extended section 1661 and recessed towards the center. The inner lifting section 1663 is bent. The movable column 165 has a transverse relief groove 1651 with a length greater than the thickness of the movable strip 166. The inner lifting section 1663 is nested and engaged in the relief groove 1651. The relief groove 1651 has space for the inner lifting section 1663 to move in the direction towards the center. Furthermore, the inner lifting section 1663 provides deformation allowance for the extended sections 1661 on both sides to expand, so that the relief groove 1651 can... When the movable bar 166 swings upward, it forces the inner lifting section 1663 in the middle to push out the outer sections 1661 on both sides a little. This deformation distance is greater than the original gap between the outer sections 1661 and the fixed ring 164 after the swing. This causes the part of the outer section 1661 close to the inner lifting section 1663 to push against the upper fixed ring 164. Then, restricted by the fixed ring 164, the outer section 1661 is squeezed on the fixed ring 164. The relief groove 1651 provides space for the inner lifting section 1663 to move during the squeezing process. The outer section 1661 also causes the movable bar 166 and the fixed ring 164 to vibrate during the squeezing with the fixed ring 164.

[0046] Meanwhile, an operation port 141 is provided on the top partition 14. Several movable columns 165 are connected together to a collecting rod 167, which passes through the top cover 162 and the operation port 141 into the top tank 15. A laterally extending connecting beam 1671 is fixed to the bottom end of the collecting rod 167. The top end of the movable column 165 is detachably fixed to the end of the connecting beam 1671. The top ends of the array of fixed rings 164 and movable bars 166 are spaced from the top cover 162. The filtration mechanism 16 includes a top spring 168 to provide downward elastic force for the collecting rod 167. The top spring 168 is nested in the connecting beam 1671 and the top partition 165. Between the covers 162 and located outside the main column 163, at this time, when the top spring 168 completes its function of providing downward elastic force for the plug rod 167, the connecting beam 1671 and the movable column 165, the top spring 168 forms a second filter grid structure. Specifically, the top spring 168 is a spring and the coil diameter is equal to the diameter of the fixed ring 164 and the movable bar 166. The coil gap of the top spring 168 that drives the movable column 165 downward to the limit of the travel of the movable column 165 is equal to the gap between the fixed ring 164 and the movable bar 166, thus forming a filter grid structure similar to the fixed ring 164 and the movable bar 166.

[0047] For the vibration-generating part, a top vibration mechanism 19 is fixedly installed on the rotating shaft 171 inside the top tank 15, which is in conjunction with the collecting rod 167 of the filter mechanism 16 for lifting and lowering transmission. The bottom column connecting ring 1631 is provided with a limiting seat 1635, and a through hole is opened in the middle of the limiting seat 1635. A guide shaft 1652 is fixed at the bottom end of the movable column 165, and the guide shaft 1652 slides and nests on the limiting seat 1635. It should be noted that the depth of the through hole of the limiting seat 1635 is greater than the maximum stroke distance of the top vibration mechanism 19 driving the collecting rod 167 to move. The movable column 165, driven downward by the elastic force of the top spring 168, abuts against the limiting seat 1635, thereby restricting the up and down movement of the collecting rod 167 and the movable column 165.

[0048] Meanwhile, the collecting rod 167 and the top cover 162 are in piston-type sealing sliding engagement. The top of the collecting rod 167 is detachably fixed with a lifting plate 1672. The top vibration mechanism 19 includes a crossbeam 191 fixed on the rotating shaft 171 and extending laterally, a top vibration motor 193 fixed on the crossbeam 191, and a rotating buckle frame 194 connected to the top vibration motor 193. The top vibration mechanism 19 drives the collecting rod 167 to perform vertical lifting activities through the rotating buckle frame 194 and the lifting plate 1672.

[0049] Specifically, the rotating frame 194 includes a base connected to the shaft of the top vibrating motor 193, a vertical structural wall 1941 extending downward from the base and fixed thereto, and a bottom extension platform 1942 fixed to the bottom end of the vertical structural wall 1941. The bottom extension platform 1942 extends toward the central axis of the rotating frame 194, and the inner side of the bottom extension platform 1942 is provided with an inclined top slope 1943 that slopes from low to high. The top of the inclined top slope 1943 has a vertical drop area on the other side of the inclined surface; the lifting plate 1672 is... The circular plate 1672 has a portion that tapers toward the center, forming a side step 1673. The sloping top 1943 rotates to approach the side step 1673, abuts against the side step 1673, abuts against the bottom of the lifting plate 1672, and then disengages from the abutment. After disengaging, the filter rod 167 and the movable column 165 fall and hit the base 161, thereby generating a vibration in the entire filter mechanism 16, and causing the movable bar 166 and the fixed ring 164 to vibrate to a certain extent.

[0050] It should be noted that the distance between the vertical structural wall 1941 and the central axis of the rotating shaft 171 is less than the difference between the distance between the central axis of the stopper rod 167 and the central axis of the rotating shaft 171 and the radius of the stopper rod 167.

[0051] In this embodiment, the portion of the plug rod 167 extending out of the top partition 14 has a side working groove 1677. A limiting head 1675 is slidably nested in the side working groove 1677. A limiting spring 1674 is provided between the limiting head 1675 and the inner wall of the side working groove 1677. A limiting frame 142 is detachably and fixedly installed at the top of the operation port 141 of the top partition 14. The limiting frame 142 has a horizontal plate structure. The top of the limiting head 1675 is flat and abuts against the bottom of the limiting frame 142, thereby restricting the upward movement freedom of the plug rod 167. The bottom of the limiting head 1675 is inclined, so that after the bottom of the limiting head 1675 contacts the limiting frame 142, it can be pushed back into the side working groove 1677. At this time, the spring force of the top spring 168 mainly drives the movable column 165 to remain in the original position.

[0052] The side working groove 1677 has an upwardly extending groove portion. A vertically upwardly extending operating block 1676 is fixed to the top of the limiting head 1675. The limiting head 1675 does not have a limiting structure in the direction of the limiting spring 1674 within the side working groove 1677. The limiting head 1675 is limited in the direction of the limiting spring 1674 by the operating extension block 1676 abutting against the limiting frame 142. The bottom end of the operating extension block 1676 is spaced from the head of the limiting head 1675. The beam 191 abuts against the limit frame 142 at this interval. At the same time, the end of the crossbeam 191 is fixed with an unlocking piece 192. The unlocking piece 192 is used to abut against the operating extension block 1676 to move the limit clamp head 1675 into the side working groove 1677. The edge of the head of the unlocking piece 192 is arc-shaped to push the operating extension block 1676 to move it. The distance from the head of the unlocking piece 192 to the central axis of the rotating shaft 171 is greater than the sum of the distance from the central axis of the plug rod 167 to the central axis of the rotating shaft 171 and the radius of the plug rod 167.

[0053] By setting the distance between the vertical structural wall 1941 and the central axis of the rotating shaft 171 to be less than the difference between the distance between the central axis of the plug rod 167 and the central axis of the rotating shaft 171 and the radius of the plug rod 167, and by setting the distance between the head of the unlocking piece 192 and the central axis of the rotating shaft 171 to be greater than the sum of the distance between the central axis of the plug rod 167 and the central axis of the rotating shaft 171 and the radius of the plug rod 167, the crossbeam 191 will not directly collide with the plug rod 167 when it drives the unlocking piece 192 to rotate. At the same time, when the crossbeam 191 drives the rotating buckle frame 194 to rotate, it is only necessary to keep the vertical structural wall 1941 close to the side of the rotating shaft 171 to avoid interference with the plug rod 167.

[0054] It should also be noted that the length of the operating extension block 1676 is greater than the thickness of the inclined top slope 1943. Since the unlocking piece 192 pushes against the operating extension block 1676, the rotating bracket 194 will drive the block rod 167 to rise. At this time, it is necessary to keep the operating extension block 1676 still being pushed against.

[0055] In summary, during the specific implementation of the separation operation, this equipment is installed inside the container 3 and used independently of the ship. There is no need to worry about the ship's operation factors or the environmental factors of the sea surface. After the ship docks, the container is transported to the shore, and the inlet pipe 101 is connected to the ship's ballast water pipe. The ship's ballast water enters the tank structure through the inlet tank 13, and then enters the filter mechanism 16. The ballast water is intercepted and separated by the filter grid structure formed by the fixed ring 164 and the movable bar 166 and the filter grid structure formed by the top spring 168 of the filter mechanism 16. The solids are retained in the filter mechanism 16, while the water passes through the filter mechanism 16 and enters the main tank 11, and is discharged through the outlet pipe 102 into the next equipment.

[0056] During backwashing, one of the filter mechanisms 16 is backwashed. The backwash motor 18 drives the rotating shaft 171 to rotate, and the rotating shaft 171 aligns the receiving pipe 173 below with the exchange port 121 of the bottom partition 12 below the filter mechanism 16 that needs backwashing. At this time, the other filter mechanisms 16 are performing normal filtration and separation operations. The water that enters the main tank 11 after filtration by the other filter mechanisms 16 is flushed into the filter mechanism 16 that needs backwashing. The rotating shaft 171 causes the upper crossbeam 191 to drive the rotating buckle frame 194 and the unlocking plate 19. 2. When the water flows to both sides of the filter rod 167, the water flows into the filter mechanism 16 and carries the solids trapped inside the filter mechanism 16 downwards into the receiving pipe 173. The water is then discharged through the backwash pipe 172 and the discharge pipe 103. After the current filter mechanism 16 is backwashed, the rotating shaft 171 rotates and drives the receiving pipe 173 to rotate towards the next filter mechanism 16. The backwashing operation is performed on each filter mechanism 16 in sequence to clean the solids trapped inside the filter mechanism 16.

[0057] The unlocking plate 192, rotated into position, presses against the operating extension block 1676, causing the limit latch 1675 to retract and disengage from the limit frame 142, allowing the rise of the block rod 167 to be unrestricted. Then, the top vibration motor 193 drives the rotating buckle frame 194 to rotate, and the lower position of the inclined top slope 1943 slowly contacts the lifting plate 1672. Then, the contact position between the inclined top slope 1943 and the lifting plate 1672 continuously rises, that is, the lifting plate 1672 is continuously lifted upward. At this time, firstly, the movable column 165 pulls the inner lifting section 1663, causing the movable bar 166 to swing upward. Since the inner lifting section 1663 moves a certain distance within the relief groove 1651 after being lifted, the vertical change in the position of the inner lifting section 1663 is relatively large, while the lateral change in the movement within the relief groove 1651 is relatively small. Therefore, the distance between the inner lifting section 1663 and the side shaft section 1662 will objectively increase, causing the movable bar 166 to deform outward when it is pulled up, which will cause it to rub against the adjacent fixed ring 164, thus causing both the fixed ring 164 and the movable bar 166 to vibrate; secondly, the top spring 168 contracts, reducing the gap and increasing the flow velocity in the gap of the top spring 168, thus obtaining a better flushing effect. At the same time, the movable bar 166 moves closer to an adjacent fixed ring 164, which also reduces the gap between the movable bar 166 and the fixed ring 164, increasing the flow velocity at that point and obtaining a better flushing effect there. At the same time, the gap space between adjacent fixed rings 164 is also increased due to the displacement of the movable bar 166, ensuring that water flows in to carry the objects inside.

[0058] After the top of the inclined top slope 1943 rotates and disengages from the lifting plate 1672, the collecting rod 167 and the movable column 165 fall and impact the base 161 driven by the top spring 168. This causes the entire filter mechanism 16 to vibrate, and also causes the movable bar 166 and the fixed ring 164 to vibrate to a certain extent, thereby achieving a better vibration and shaking effect, which facilitates the cleaning of some adsorbent organisms.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
