The recovery tank 2 is arranged on the outer wall of the treatment tank 1, which is opposite to the side of the feed channel 11, and a baffle 21 is arranged between the recovery tank 2 and the treatment tank 1; the recovery tank 2 and the treatment tank 1 can be directly built on two sides of a target river channel, and cement concrete and other materials can be used.
The sliding rails 14 are arranged at two sides of the top of the treatment tank 1 and extend to two sides of the recovery tank 2; the upper side of the sliding rail 14 is provided with a supporting sliding plate 15, the supporting sliding plate 15 is in sliding connection with the sliding rail 14 through a sliding block 151 arranged at the bottom, the sliding rail 14 and the sliding block 151 can adopt an electric rail and an electric sliding block device in the existing market, an operator can control the sliding block 151 to drive the supporting sliding plate 15 to slide and move on the sliding rail 14 through a controller in the outside; the support slide plate 15 is provided with a separation plate 3, the separation plate 3 is connected with a telescopic end of a telescopic device 31 arranged on the bottom of the support slide plate 15, and the telescopic device 31 can be a device with a telescopic function such as an electric telescopic rod.
The specific working flow is as follows: in the dredging process of the river channel, the sludge in the river channel is transferred onto a feeding conveyor belt 12 positioned on a feeding channel 11 through equipment in a dredging module, then the sludge moves in the feeding channel 11 under the action of the feeding conveyor belt 12 until the tail end of the feeding conveyor belt 12, the sludge slides into the feeding channel 11 and flows downwards under the action of the inclined feeding channel 11, and the sludge enters the inside of the treatment tank 1 after passing through an interception grille 13; in the process, the garbage sundries with larger volume in the sludge are intercepted by the interception grille 13 and blocked outside the treatment tank 1, so as to be separated from the sludge; an operator beside the device can timely use tools to clean the large-volume garbage sundries intercepted on the interception grille 13, and the smoothness of the feeding channel 11 is ensured.

The specific working flow is as follows: on the basis of the specific workflow in example 2, when the separation plate 3 slides at the liquid level portion, the river water tends to flow toward the inside of the separation plate 3 with respect to the separation plate 3 due to the inertial action of the river water at the liquid level portion; the part of the drainage plate 34, which is opposite to the flowing direction of the river water, is an inclined guiding part 342, so that the river water smoothly flows into the separation plate 3; then, river water and garbage are separated from the inside of the separation plate 3, and the garbage remains inside the separation plate 3.
When the garbage limited in the separating plate 3 has a flowing trend, the garbage can be intercepted by the flow limiting part 341 of the vertical surface of the drainage plate 34 at the opening position of the separating plate 3, so that the garbage in the separating plate 3 is difficult to flow out, the limiting effect of the garbage in the separating plate 3 is ensured, the flowing out of the garbage is reduced, and the collecting and recycling efficiency of the separating plate 3 to the garbage is improved.
When the first driving device 332 is activated so that the separating plate 3 is opened downward, the flow restriction 341, which is a vertical surface at this time, becomes a horizontal surface, so that the waste inside the separating plate 3 is sufficiently discharged; as shown in fig. 12, the second driving device 346 is started, so that the drainage plate 34 rotates relative to the separation plate 3, the horizontal flow-limiting part 341 is changed into a vertical surface state under the rotation action, and the part where the inclined guiding part 342 is located rotates to the outer side of the opening of the separation plate 3, so that the outlet of the separation plate 3 is not blocked, the internal garbage can flow out conveniently, and the garbage can fully enter the recovery tank 2; thus, the floating garbage on the liquid level is more fully brought into the recovery tank 2, so that the collection treatment is achieved, and the adverse effect of floating plastic garbage in the subsequent screening treatment is reduced.
Example 4
On the basis of embodiment 3, as shown in fig. 2-12 in the drawings of the specification, a cleaning cavity 343 is formed in the drainage plate 34, cleaning holes 344 are uniformly formed in the drainage plate 34 at the surface of the flow-limiting part 341, the cleaning holes 344 are obliquely downward, and the cleaning holes 344 are communicated with the interior of the cleaning cavity 343; the cleaning hole 344 is a tapered hole with a smaller opening section, and a filter screen is arranged in the middle of the cleaning hole, so that the problem of blockage caused by the fact that sundries in river water enter the cleaning cavity 343 through the cleaning hole 344 while the impact cleaning water flow is ensured to be formed is avoided.
The cleaning chamber 343 is communicated with an external water source through a flow guide pipe 345 arranged at the end part; the external water source can be a water tank arranged on the supporting slide plate 15 and communicated with the cleaning cavity 343 through the guide pipe 345, and the miniature water pump is arranged on the guide pipe 345, so that the water in the water source can enter the cleaning cavity 343 through the guide pipe 345 under the action of an external controller; the flow guide pipe 345 adopts a telescopic hose structure, so that the communication between an external water source and the flow guide plate 34 is maintained after the flow guide plate 34 rotates.
The specific working flow is as follows: on the basis of the specific working procedure in embodiment 3, when the drainage plate 34 moves to the upper side of the recovery tank 2, the flow restrictor 341 is in a vertical state under the rotation action of the second driving device 346; in the process of dumping the floating garbage collected inside the recovery tank 2, since the garbage is stuck with the sludge, and the flow restriction 341 plays a limiting role on the garbage inside in the sliding process of the separation plate 3, the sludge sticking role makes it difficult for the garbage to fall down also stuck on the contacted flow restriction 341.
Therefore, when dumping the garbage collected in the separating plate 3, the micro water pump is started, so that the cleaning water in the external water source enters the cleaning chamber 343 in the drainage plate 34 through the guide pipe 345, and then flows out of the cleaning holes 344 on the flow limiting part 341, so that the garbage adhered on the surface of the flow limiting part 341 falls off under the flushing action of the cleaning water flowing out of the cleaning holes 344 and enters the recovery tank 2.
And, the drainage plate 34 rotates the back under No. two actuating device 346, relative separator plate 3, and the downward clearance hole 344 opening orientation of slope is originally changed into the slope and upwards points to inside the separator plate 3, increase miniature water pump power this moment for the rivers that flow out strike the inside arc surface of separator plate 3, thereby accelerate the rubbish of adhesion on the inside surface of separator plate 3 drop under the rivers impact, make the rubbish that separator plate 3 inside was collected obtain fully retrieving, and then guarantee separator plate 3 normal work, improve the recovery processing efficiency to liquid level rubbish.
Example 5
On the basis of the embodiment 4, as shown in fig. 2-6 in the drawings of the specification, stirring plates 16 are uniformly arranged on one side end part of the supporting slide plate 15, which is close to the feeding channel 11, and the stirring plates 16 are arc-shaped; the bottom of the stirring plate 16 is sharp and embedded in the treatment tank 1 at a position near the bottom; the upper surface of the bottom of the treatment tank 1 is uniformly provided with a sliding groove 17, the sliding groove 17 is parallel to the sliding rail 14, and the bottom of the stirring plate 16 is embedded in the sliding groove 17.
The specific working flow is as follows: on the basis of the specific workflow in the embodiment 4, in order to facilitate the full separation of the garbage inside the sludge, the sludge needs to be stirred, but the existing stirring sludge is usually stirred by an operator from the outside of the sludge from top to bottom, the resistance is large, and the stirring effect is difficult to be transferred to the sludge at the lower layer, so that the sludge is fully turned; therefore, in the case of providing the agitation plate 16 supporting the slide plate 15, the end of the agitation plate 16 is directly located in the sliding groove 17 at the bottom of the recovery tank 2.
After the sludge enters the treatment tank 1, the bottom of the stirring plate 16 is buried in the bottom of the sludge, so when the supporting slide plate 15 drives the stirring plate 16 to slide, the end part of the stirring plate 16 firstly slides on the bottom of the sludge, the deposited sludge is stirred from bottom to top, the resistance of stirring the sludge is reduced, the part of the sludge inside the bottom layer is fully turned, the mixed garbage is separated out, and the garbage floats to the liquid level part under the action of buoyancy, so that the garbage can be conveniently collected and recovered, and the garbage content inside the sludge in the treatment tank 1 is further reduced.
Further, the end of the stirring plate 16 slides along the sliding groove 17, and when the sliding force of the stirring plate 16 has a tendency of bending towards two sides, the sliding groove 17 plays a role in limiting and supporting the stirring plate 16, so that the stirring plate 16 is ensured to maintain a fixed sliding track, bending deformation during sliding is reduced, and the service life of the stirring plate is prolonged.
Example 6

The specific working flow is as follows: based on the specific work flow in example 5, during the sliding process of the stirring plate 16, the bottom of the stirring plate 16 is stirred from bottom to top, so that the bottom part of the sludge is turned upwards, and the garbage in the bottom of the sludge forms a lump under the adhesion effect of the contacted sludge; thus, when the agitating plate 16 slides, the flipping plate 161 slides therewith; the liquid level of the turning plate 161 drives the contacted river water, the turned-up sludge flows upwards along the inclined plane on the turning plate 161 under the drive of the river water and passes through the part of the crushing cone block 162 on the inclined plane part, in the process, the river water and the thinned sludge can smoothly pass through the gap between the crushing cone blocks 162, and the agglomerated aggregate is crushed and dispersed in the collision contact process with the conical end part of the crushing cone block 162, so that the plastic garbage in the plastic aggregate is separated and released and floats to the upper layer, thereby improving the garbage recycling efficiency.
And in the working process of the stirring plate 16, if less river water is in the sludge, the depth of the river water in the upper layer of the formed sludge is shallow, and the stirring can cause unstable liquid level, so that the working of the separation plate 3 is not facilitated; at this time, the agitating plate 16 may be provided as a detachable connection, for example, by bolting to the support slide plate 15; when the stirring plate 16 works, the telescopic device 31 is controlled so that the separating plate 3 moves upwards to be away from the liquid level part, after stirring is complete, the stirring plate 16 is disassembled, after standing for a period of time, the separating plate 3 moves downwards to contact with the liquid level part, and garbage at the liquid level part is collected and recycled.
