[0034] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] Referring to FIGS. 1-13, a water ecological environment treatment device includes a bottom plate 1, a support table 2 fixedly installed on the upper surface of the bottom plate 1, a top cover 3 fixedly installed on the upper surface of the support table 2, a feeding table 4 rotatably installed on the upper surface of the support table 2, the feeding table 4 being installed between the top of the support table 2 and the top wall of the top cover 3, and the top end of the feeding table 4 being attached to the top wall of the top cover 3, a plurality of material receiving grooves 5 being equidistantly and circumferentially provided on the upper surface of the feeding table 4, a feeding hopper 42 corresponding to the material receiving grooves 5 being fixedly installed on the upper surface of the top cover 3, a drain port 9 and a discharging port 10 corresponding to the material receiving grooves 5 being respectively provided on the upper surface of the support table 2, the width of the discharging port 10 being wider than the width of a filter plate 8, and the width of the drain port 9 being narrower than the width of the filter plate 8; so that when the filter plate 8 moves to the discharging port 10, the bottom of the filter plate 8 loses the support of the support table 2 and can be flipped downward to unload under the action of gravity; when the filter plate 8 moves from the discharging port 10 to the drain port 9, the back of the filter plate 8 is flipped upward under the extrusion of the edge of the drain port 9, so that the filter plate 8 can continue to block the bottom of the material receiving groove 5, the bottom of each material receiving groove 5 is hingedly connected with the filter plate 8, a compression mechanism for extruding sludge is installed in the material receiving groove 5, a stepping motor 43 is fixedly installed at the top end of the top cover 3, the output end of the stepping motor 43 penetrates the top wall of the top cover 3 and is fixedly installed with the rotation center of the feeding table 4, a water receiving tank 44, a dry sludge tank 45 and a wet sludge tank 46 are respectively installed on the upper surface of the bottom plate 1 corresponding to the drain port 9 and the discharging port 10, and the dry sludge tank 45 and the wet sludge tank 46 are both installed below the discharging port 10.

[0036] The compression mechanism includes a pressing plate 6 slidingly installed on the inner wall of the receiving groove 5. The top end of the pressing plate 6 is fixedly installed with a baffle 7 facing the outer side of the feeding table 4. The upper surface of the baffle 7 is flush with the top of the feeding table 4. A gas bag 11 is fixedly installed between the side of the pressing plate 6 close to the baffle 7 and the inner wall of the receiving groove 5. A plurality of tension springs 12 are fixedly installed between the side of the pressing plate 6 close to the gas bag 11 and the inner wall of the receiving groove 5. The outer surface of the gas bag 11 is fixedly installed with a conduit 13 communicating with the inside of the gas bag 11. The conduit 13 penetrates through the outer periphery of the feeding table 4 and is fixedly installed therewith. The outer surface of the end of the conduit 13 close to the gas bag 11 is sequentially installed with a first one-way valve 15 and a pressure relief valve 16 in communication with the inside thereof. The first one-way valve 15 is used to ensure that the gas injected into the gas bag 11 cannot flow back and escape. The first one-way valve 15 can unidirectionally conduct gas flow into the inside of the gas bag 11. The end of the conduit 13 away from the gas bag 11 is installed with a gas injection mechanism. The outer surface of the conduit 13 between the gas bag 11 and the first one-way valve 15 is installed with a gas release assembly. The gas injection mechanism includes a gas injection cylinder 14 fixedly installed at the end of the conduit 13 away from the gas bag 11. The gas injection cylinder 14 communicates with the inside of the conduit 13. The end of the gas injection cylinder 14 away from the conduit 13 is penetratingly slidingly installed with a push-pull rod 17. The end of one end of the push-pull rod 17 is fixedly installed with a movable plug 18. The movable plug 18 is slidingly installed with the inner wall of the gas injection cylinder 14. The other end of the push-pull rod 17 is fixedly installed with a transverse guide frame 19. The outer surface of the movable plug 18 is penetratingly embedded with a second one-way valve 20 unidirectionally conducting to the inside of the gas injection cylinder 14. The second one-way valve 20 is used to ensure that when the movable plug 18 is pulled, the air outside can enter the gas injection cylinder 14.

[0037] In use, the sludge is poured into the feeding hopper 42, and the sludge falls into the receiving groove 5 opened on the feeding table 4 (the filter plate 8 below the feeding hopper 42 is in a horizontal state under the pushing of the supporting table 2, so that the filter plate 8 blocks the bottom of the receiving groove 5), the feeding table 4 is driven to rotate counterclockwise by the stepping motor 43, and the gear plate 22 is moved by the Z-shaped plate 21 during the rotation of the feeding table 4. When the gear plate 22 is engaged with the incomplete inner tooth ring 39, the gear plate 22 will rotate, and the guide column 23 installed on the gear plate 22 can reciprocate in the air cylinder 14 through the transverse guide frame 19 and the push-pull rod 17 to drive the movable plug 18 to inject air into the air bag 11 through the conduit 13 under the cooperation of the second one-way valve 20 (the bottom end of the moving rod 27 abuts against the top end of the incomplete top ring 40 at this time, so that the plunger 26 blocks the air vent 25 opened on the air release pipe 24, and the conduit 13 is prevented from leaking), so that the air bag 11 expands to drive the pressing plate 6 and the baffle 7 to move, the pressing plate 6 can extrude the sludge in the receiving groove 5, the water in the sludge falls into the water receiving tank 44 through the filter plate 8, and the dewatering effect of the sludge is realized. When the sludge in the receiving groove 5 is compressed and compacted, the air bag 11 cannot expand and drive the pressing plate 6 to move, so that the gas in the conduit 13 cannot be injected into the air bag 11. At this time, the excessive gas in the conduit 13 pushes open the pressure relief valve 16 and is discharged from the pressure relief valve 16, so as to ensure the normal operation of the air injection mechanism and avoid the jamming phenomenon.

[0038] In this embodiment, the air release assembly includes an air release pipe 24 fixedly installed on the outer surface of the conduit 13, the air release pipe 24 is in communication with the inside of the conduit 13, the outer surface of the air release pipe 24 is penetrated to form an air release opening 25, the plunger 26 is slidably installed on the inner wall of the air release pipe 24 and can block the air release opening 25, the bottom end of the plunger 26 is fixedly installed with a moving rod 27, the bottom end of the moving rod 27 penetrates the bottom end of the air release pipe 24 and is fixedly installed with a stop ring 28, the outer surface of the moving rod 27 is sleeved with a return spring 29, the return spring 29 is arranged between the bottom end of the air release pipe 24 and the stop ring 28, the upper surface of the supporting table 2 is fixedly installed with an incomplete top ring 40, the notch of the incomplete top ring 40 corresponds to the position of the material falling opening 10, and the two end portions of the incomplete top ring 40 are both arranged as inclined surfaces, and the bottom end of the moving rod 27 intermittently abuts against the top end of the incomplete top ring 40.

[0039] When the mobile rod 27 is separated from the top end of the incomplete top ring 40 and moves to the gap of the incomplete top ring 40, the mobile rod 27 will drive the plunger 26 to move downward under the elastic force of the reset spring 29, so that the plunger 26 opens the air vent 25, the gas in the air bag 11 can be discharged through the air vent 25, and the pressure plate 6 is pulled outward by the plurality of tension springs 12, so that the air bag 11 is contracted, the pressure plate 6 is reset, and the pressure plate 6 no longer extrudes the compressed and dewatered sludge block, facilitating the unloading of the sludge block.

[0040] In the embodiment, a classification locking mechanism is installed between the baffle plate 7 and the filter plate 8. The classification locking mechanism comprises a latch block 33 fixedly installed on the hinged side of the filter plate 8. The feeding table 4 is provided with a mounting groove 30 corresponding to the lower surface of the latch block 33. A damping plate 31 is movably installed on the inner wall of the mounting groove 30. The damping plate 31 and the mounting groove 30 have a certain friction force, so that the damping plate 31 can remain stationary when being moved to any position. One end of the damping plate 31 is fixedly installed with a latch rod 32 matched with the latch block 33. A push lock assembly is installed between the baffle plate 7 and the damping plate 31. The push lock assembly comprises a spring rod 35 fixedly installed on the lower surface of the baffle plate 7. The extension end of the spring rod 35 is fixedly installed with a push plate 36 corresponding to the position of the damping plate 31. A give way assembly is installed between the push plate 36 and the feeding table 4. The give way assembly comprises a first inclined block 37 fixedly installed on the outer surface of the push plate 36 close to the feeding table 4. The outer periphery of the feeding table 4 is fixedly installed with a top rod 38 corresponding to the first inclined block 37. The lower surface of the end of the damping plate 31 away from the latch rod 32 is fixedly installed with a second inclined block 34. The upper surface of the support table 2 close to the discharge opening 10 is fixedly installed with a push column 41 for lifting the second inclined block 34.

[0041] When the relatively dry sludge is compressed and dewatered, the baffle plate 7 will not move the push plate 36 to the damping plate 31 during the movement, so that the push plate 36 will not move the damping plate 31, the latch rod 32 will not be inserted into the latch block 33, and the filter plate 8 will not be temporarily locked. When the feeding table 4 drives the filter plate 8 to move to the front half of the discharge opening 10, the filter plate 8 loses the support of the support table 2 and automatically flips downward under its own weight, so that the compressed and dewatered relatively dry sludge falls into the dry sludge box 45 for collection.

[0042] When the wet sludge is compressed and dewatered, the dewatering amount of the wet sludge is large, so that the moving stroke of the baffle 7 is increased, the baffle 7 is moved to push the damping plate 31 to move through the push plate 36, the pin rod 32 installed at the end of the damping plate 31 is inserted into the pin block 33, the filter plate 8 is temporarily locked, the locked filter plate 8 cannot be turned down when moving to the front half of the discharge port 10, and the discharge is not performed; until the feeding table 4 drives the filter plate 8 to move to the rear half of the discharge port 10, and the inclined surface of the second inclined block 34 installed at the bottom of the damping plate 31 abuts against the push column 41, the push column 41 pushes the damping plate 31 and the pin rod 32 as a whole out of the pin block 33 through the second inclined block 34 to the original position, the filter plate 8 is unlocked, and the wet sludge after being compressed and dewatered on the filter plate 8 is discharged into the wet sludge tank 46 for collection.

[0043] When the baffle 7 is driven by the spring rod 35 to move the push plate 36 to the end position of the jacking rod 38, it indicates that the damping plate 31 has been pushed to the position close to the limit, at this time, when the push plate 36 continues to move, the end of the jacking rod 38 pushes the push plate 36 to the direction of the spring rod 35 through the inclined surface of the first inclined block 37, so that the push plate 36 is separated from the damping plate 31, so that the baffle 7 can continue to move under the driving of the pressing plate 6.

[0044] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: in use, the sludge is poured into the feeding hopper 42, the sludge falls into the receiving groove 5 opened on the feeding table 4 (the filter plate 8 located below the feeding hopper 42 is in a horizontal state under the pushing of the supporting table 2, and the filter plate 8 blocks the bottom of the receiving groove 5), the feeding table 4 is driven to rotate counterclockwise by the stepping motor 43, and the Z-shaped plate 21 drives the gear disc 22 to move when the feeding table 4 rotates, after the gear disc 22 and the incomplete inner tooth ring 39 are engaged, the gear disc 22 will rotate, so that the guide column 23 installed on the gear disc 22 can reciprocate in the air cylinder 14 through the horizontal guide frame 19 and the push-pull rod 17 when rotating, so that the movable plug 18 continuously injects external air into the air bag 11 through the conduit 13 under the cooperation of the second one-way valve 20 (at this time, the bottom end of the moving rod 27 abuts against the top end of the incomplete top ring 40, so that the plunger 26 blocks the air vent 25 opened on the air release pipe 24, and the conduit 13 is prevented from leaking), so that the air bag 11 expands to push the pressing plate 6 and the baffle 7 to move, the pressing plate 6 can extrude the sludge in the receiving groove 5, and the water in the sludge falls into the water receiving tank 44 for collection, realizing the dewatering effect of the sludge;

[0045] When the sludge in the receiving groove 5 is compressed to a compacted state, the air bag 11 can no longer expand and push the pressing plate 6 to move, and the gas in the conduit 13 can no longer be injected into the air bag 11. At this time, the excessive gas in the conduit 13 will push open the pressure relief valve 16 and be discharged from the pressure relief valve 16, ensuring the normal operation of the gas injection mechanism and avoiding the occurrence of a jamming phenomenon.

[0046] By pushing the pressing plate 6 to move through the air bag 11 to compress and dewater the sludge, and automatically stopping the extrusion of the sludge when the sludge is compressed to a compacted state, damage caused by continuing operation when the compression mechanism reaches the compression limit can be avoided, and the compression stroke can be automatically adjusted according to the dryness of the sludge dewatered each time, ensuring that the sludge of different dryness can be adaptively dewatered to the corresponding effect each time.

[0047] When the sludge is compressed and dewatered, the baffle 7 will not move the push plate 36 to the damping plate 31 during movement, so that the push plate 36 will not push the damping plate 31 to move, the pin shaft 32 will not be inserted into the pin block 33, and the filter plate 8 will not be temporarily locked. When the filter plate 8 is moved to the front half of the discharge opening 10 by the feeding table 4, the filter plate 8 loses the support of the support table 2 and automatically flips down under its own weight, so that the relatively dry sludge after compression and dewatering falls into the dry sludge box 45 for collection.

[0048] When the sludge is compressed and dewatered, the baffle 7 will not move the push plate 36 to the damping plate 31 during movement, so that the push plate 36 will not push the damping plate 31 to move, the pin shaft 32 will not be inserted into the pin block 33, and the filter plate 8 will not be temporarily locked. When the filter plate 8 is moved to the front half of the discharge opening 10 by the feeding table 4, the filter plate 8 loses the support of the support table 2 and automatically flips down under its own weight, so that the relatively dry sludge after compression and dewatering falls into the dry sludge box 45 for collection.

[0049] By classifying and collecting the sludge compressed and dewatered at different humidities (the sludge with different water contents differs in physical properties and chemical composition), more effective resource recovery (such as recovering organic matter, heavy metals or other valuable elements) can be performed according to the characteristics, and the classified sludge can be treated according to different subsequent treatment needs, reducing the treatment cost.
