Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range of protection of the utility model.
[0029] Reference Figures 1-3 , the utility model provides an embodiment: water environment ecological management is used sludge removal equipment, including collection box 1 and sludge treatment box 2, sludge treatment box 2 bottom installation is in collection box 1 top, and sludge treatment box 2 top fixedly connected with water pump 4, and the output of water pump 4 is fixedly connected with connecting pipe 3, and the input of water pump 4 is fixedly connected with extraction pipe 5, and sludge treatment box 2 inside is provided with push assembly 6, and collection box 1 inside is provided with anti-solidification assembly 7;
[0030] Collection box 1 is connected with sludge treatment box 2, provides stable support for sludge treatment box 2 on one hand, and sludge treatment box 2 screened and handled sludge can fall into collection box 1 on the other hand, realizes the transfer of material, passes through the driving suction force of water pump 4, and sludge under water is extracted after through extraction pipe 5 and enters sludge treatment box 2 in connecting pipe 3, ensures that sludge in the bottom of water area can be effectively cleaned up.Push assembly 6 can separate sludge and impurities, stone in the sludge entering sludge treatment box 2.Anti-solidification assembly 7 avoids sludge solidification and agglomeration in collection box 1 and affects discharge.
[0031] The pushing assembly 6 comprises a cylinder 61 fixedly connected to the top of the collecting box 1, a connecting rod 62 fixedly connected to the output end of the cylinder 61, a sleeve 63 rotatably connected to the outer portion of the connecting rod 62, a screening plate 64 fixedly connected to the inner wall of the sludge treatment box 2, and the sleeve 63 is rotatably connected to the top of the screening plate 64.
[0032] The driving of the cylinder 61 enables the connecting rod 62 to move linearly and drives the sleeve 63 to roll on the screening plate 64, so that the convex rods 65 can penetrate into the sludge and push the sludge in all directions, ensuring that the sludge falls through the screening plate 64, while impurities and stones are pushed to the discharge port 9, achieving efficient separation.
[0033] With reference to Figures 2-4 The anti-solidification assembly 7 comprises a motor 71 fixedly connected to the outer right side of the collecting box 1, a rotating rod 72 fixedly connected to the output end of the motor 71, and stirring blades 73 fixedly connected to the outer portion of the rotating rod 72, and the end of the rotating rod 72 away from the motor 71 is rotatably connected to the inner side wall of the collecting box 1.
[0034] The power of the motor 71 is transmitted to the stirring blades 73, which can effectively keep the sludge in a flowing state under the driving of the rotating rod 72, preventing local static solidification of the sludge in the collecting box 1.
[0035] With reference to Figures 1-2 The sleeve 63 is externally fixedly connected with a plurality of convex rods 65, the cylinder 61 is located at the front end of the sludge treatment box 2, the rear end of the sludge treatment box 2 is provided with a discharge port 9, the connecting pipe 3 is fixedly connected to the top of the sludge treatment box 2 at the end away from the water pump 4, the top of the collecting box 1 is provided with a connecting port 11, the bottom of the sludge treatment box 2 is in communication with the connecting port 11, the outer portion of the collecting box 1 is provided with a discharge pipe 8 for facilitating the discharge of sludge from the collecting box 1, and a plurality of square holes are formed in the outer portion of the screening plate 64.
[0036] When the sleeve 63 moves in the sludge treatment box 2, the convex rods 65 penetrate into the sludge and push the sludge accumulated on the screening plate 64. The larger particle impurities and stones pushed by the convex rods 65 to the rear are smoothly discharged from the sludge treatment box 2 through the discharge port 9, facilitating the workers to handle the impurities. The sludge preliminarily treated by the screening plate 64 can fall into the collecting box 1 through the connecting port 11. The workers can conveniently discharge the sludge to the designated place through the discharge pipe 8. The square holes effectively block the larger particle impurities and guide them to flow to the discharge port 9.
[0037] Working principle: when the water area is dredged, the device first starts the water pump 4, and the water bottom sludge is transported to the sludge treatment box 2 through the connecting pipe 3 through the suction pipe 5. When the sludge enters the sludge treatment box 2, it will fall on the screening plate 64. At this time, the air cylinder 61 starts, driving the connecting rod 62 to move on the screening plate 64. When the connecting rod 62 moves back and forth, the sleeve 63 will roll on the screening plate 64, so that the convex rod 65 constantly pushes the sludge accumulated on the screening plate 64, so that the smaller particles of sludge and the mixed water will fall into the collecting box 1 below from the square hole, and the larger particles of impurities, stones, etc. Will be discharged from the discharge port 9, thereby realizing the preliminary sludge separation and screening;
[0038] Secondly, after the extracted sludge enters the collecting box 1, the motor 71 starts, driving the rotating rod 72 to rotate, thereby driving the stirring blade 73 to continuously stir the sludge in the collecting box 1, effectively preventing the sludge from solidifying and caking in the collecting box 1.
