DETAILED DESCRIPTION

The distance between the vertical structure wall 1941 and the center axis of the rotating shaft 171 is less than the difference between the distance between the center axis of the collecting plug rod 167 and the center axis of the rotating shaft 171 and the radius of the collecting plug rod 167, and the distance between the head of the unlocking piece 192 and the center axis of the rotating shaft 171 is greater than the sum of the distance between the center axis of the collecting plug rod 167 and the center axis of the rotating shaft 171 and the radius of the collecting plug rod 167, so that the cross beam 191 does not directly hit the collecting plug rod 167 when driving the unlocking piece 192 to rotate, and the vertical structure wall 1941 only needs to be close to one side of the rotating shaft 171 when driving the rotating clasp frame 194 to rotate, so that the vertical structure wall 1941 does not interfere with the collecting plug rod 167.

[0040] It should be noted that the length of the operation extension block 1676 is greater than the thickness of the inclined top slope 1943, because the rotating clasp frame 194 drives the collecting plug rod 167 to rise after the unlocking piece 192 abuts against the operation extension block 1676, and the operation extension block 1676 needs to be kept abutting at this time.

[0041] In summary, in the specific implementation of the separation operation, the device is installed in the box 3 of the container and used independently of the ship. It does not need to worry about the operation of the ship, environmental factors of the sea surface, etc. After the ship docks, the container is transported to the shore, the water inlet pipe 101 is connected with the ballast water pipe of the ship, the ballast water of the ship enters the tank structure through the water inlet tank 13, then enters the filter mechanism 16 upwards, and is intercepted and separated by the filter grid structure formed by the fixed ring 164 and the movable bar 166 of the filter mechanism 16 and the filter grid structure formed by the top spring 168. The solid is left in the filter mechanism 16, and the water penetrates the filter mechanism 16 into the main tank 11, and is discharged through the water outlet pipe 102 into the next device; When backwashing, one of the filter mechanisms 16 is backwashed, the backwashing motor 18 drives the rotating shaft 171 to rotate, the rotating shaft 171 makes the lower receiving pipe 173 align with the exchange port 121 of the bottom partition plate 12 below the filter mechanism 16 that needs to be backwashed. At this time, the other filter mechanisms 16 normally perform the filtering and separating operation, and the water in the main tank 11 after being filtered by the other filter mechanisms 16 flows into the filter mechanism 16 that needs to be backwashed. The rotating shaft 171 makes the upper cross beam 191 drive the rotating buckle frame 194 and the unlocking piece 192 to come to both sides of the plug rod 167. At this time, the water flow enters the filter mechanism 16 from the filter mechanism 16, and washes down the solid intercepted in the filter mechanism 16 into the receiving pipe 173, and is discharged through the backwashing discharge pipe 172 and the discharge pipe 103. After the current filter mechanism 16 is backwashed, the rotating shaft 171 drives the receiving pipe 173 to rotate towards the next filter mechanism 16, and the backwashing operation is sequentially performed on each filter mechanism 16 to clean the solid intercepted in the filter mechanism 16. The unlocked piece 192 is rotated to the position and abuts against the operation extension block 1676, so that the limiting clamp 1675 is retracted and separated from the limiting frame 142, the rising of the collecting plug rod 167 is not limited, then the vibration motor 193 drives the rotating buckle frame 194 to rotate, the low position of the inclined top slope 1943 slowly contacts the lifting plate 1672, then the contact position of the inclined top slope 1943 and the lifting plate 1672 is constantly raised, that is, the lifting plate 1672 is constantly lifted upwards. At this time, first, the movable column 165 pulls the inner lifting section 1663 to make the movable strip 166 swing upwards. Since the inner lifting section 1663 is lifted and moves in the position slot 1651 for a period, but the vertical change degree of the position of the inner lifting section 1663 is large, and the horizontal change of the movement in the position slot 1651 is small, therefore, the spacing between the inner lifting section 1663 and the side shaft section 1662 will objectively increase, so that the movable strip 166 deforms in the outward direction when being pulled up, thereby scratching the adjacent fixed ring 164, so that the fixed ring 164 and the movable strip 166 vibrate; second, the compression spring 168 is retracted, the gap is reduced, the flow rate in the gap of the compression spring 168 is increased, better flushing effect is obtained, and the movable strip 166 is close to an adjacent fixed ring 164, so that the gap between the movable strip 166 and the fixed ring 164 is reduced, the flow rate at the position is increased, so that better flushing effect is obtained at the position, and the gap space between the adjacent fixed rings 164 is increased due to the displacement of the movable strip 166, so that the water flow is ensured to flow into the object inside to carry the object. After the inclined top slope 1943 is rotated and the top of the inclined top slope 1943 is separated from the contact with the lifting plate 1672, the collecting plug rod 167 and the movable column 165 are driven to fall by the compression spring 168 and impact the base 161, so that a vibration is generated on the whole filtering mechanism 16, and the movable strip 166 and the fixed ring 164 vibrate, better vibration shaking effect is obtained, and it is convenient to clean some biological bodies with adsorption.

[0042] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the present disclosure.
