DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] In one embodiment, see Figure 1 , Figure 2 and Figure 5 A device for efficiently cleaning sludge in an oxidation ditch comprises a support plate 1, a plurality of support columns 8 are fixed on the top of the support plate 1, a separation cylinder 2 is fixed on the top of the support column 8, a plurality of water outlet holes 12 are arranged at the bottom of the separation cylinder 2, the separation cylinder 2 is used for separating accumulated water and accumulated sludge, a recovery box 5 is fixed on the top of the support plate 1, the separation cylinder 2 is connected to the recovery box 5 through a dehydration mechanism 3, the dehydration mechanism 3 is used for dehydrating the accumulated sludge, and at the same time, the dehydrated accumulated sludge is transported to the inside of the recovery box 5, and a motor 10 is installed on the top of the separation cylinder 2 A rotating rod 11 is installed at the output end of the motor 10, and the rotating rod 11 passes through the separation cylinder 2 and the support plate 1. A scraper 9 is provided inside the separation cylinder 2. The bottom of the scraper 9 is slidably connected to the bottom of the separation cylinder 2. The side wall of the scraper 9 is fixedly connected to the rotating rod 11. The lower end of the rotating rod 11 is connected to a crushing mechanism 4, which is used to crush the accumulated mud inside the oxidation ditch. A mud pump 7 is installed on the top of the support plate 1. The mud pump 7 is connected to a mud pumping pipe 6. One end of the mud pumping pipe 6 passes through the support plate 1, and the other end is connected to the separation cylinder 2.

[0024] In the present embodiment, when the device is cleaning the accumulated mud inside the oxidation ditch, the support plate 1 is driven by the hull or other floating body to move above the water surface inside the oxidation ditch, and the motor 10 and the mud pump 7 are started at the same time. Under the action of the mud pump 7, the accumulated mud and water inside the water body enter the separation cylinder 2 through the mud pumping pipe 6. Since a plurality of water outlet holes 12 are provided at the bottom of the separation cylinder 2, the accumulated water directly falls on the surface of the support plate 1 through the water outlet holes 12, and slides down the surface of the support plate 1 to the inside of the oxidation ditch again, and the accumulated mud is accumulated inside the separation cylinder 2, thereby separating the accumulated water from the accumulated mud. The purpose of mud cleaning can be achieved without draining the accumulated water inside the oxidation ditch, thereby effectively improving the cleaning efficiency of the accumulated mud in the oxidation ditch, and at the same time At the same time, under the action of the motor 10, the rotating rod 11 drives the scraper 9 to slide at the bottom of the separation cylinder 2, and drives the accumulated mud at the bottom of the separation cylinder 2 to move through the scraper 9, so that the accumulated mud inside the separation cylinder 2 enters the recovery box 5. In the process of the accumulated mud entering the recovery box 5, the dewatering mechanism 3 will dehydrate the accumulated mud, and there is no need for subsequent staff to dewater the accumulated mud again, which effectively improves the recovery efficiency of the accumulated mud. In addition, while the rotating rod 11 rotates, the crushing mechanism 4 also crushes the accumulated mud at the bottom of the oxidation ditch, thereby breaking up the accumulated mud at the bottom of the oxidation ditch, so that the mud pump 7 can smoothly extract the accumulated mud inside the oxidation ditch into the separation cylinder 2, effectively improving the cleaning efficiency of the accumulated mud in the oxidation ditch.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The dehydration mechanism 3 includes a dehydration pipe 32 that passes through the side wall of the recovery box 5. The dehydration pipe 32 is fixedly connected to the side wall of the recovery box 5. The dehydration pipe 32 is located at one end of the recovery box 5, and a plugging component is provided at the opening. The plugging component is used to plug the end of the dehydration pipe 32. The top of the dehydration pipe 32 is connected to a mud discharge pipe 31. The upper end of the mud discharge pipe 31 is connected to the separation cylinder 2. A plurality of drainage holes 312 are provided at the bottom of the dehydration pipe 32. A push block 311 is provided inside the dehydration pipe 32. The push block 311 is adapted to the dehydration pipe 32, and the push block 311 is slidably connected to the inner wall of the dehydration pipe 32. The push block 311 is connected to a pushing component, and the pushing component is used to drive the push block 311 to reciprocate. When the accumulated mud is processed, the accumulated mud will enter the dehydration pipe 32 through the mud discharge pipe 31, and the pushing assembly will drive the pushing block 311 to reciprocate inside the dehydration pipe 32. Under the action of the pushing block 311, the accumulated mud inside the dehydration pipe 32 will move toward the end of the dehydration pipe 32, and with the cooperation of the sealing mechanism, the pushing block 311 will squeeze the accumulated mud inside the dehydration pipe 32, so that the water inside the accumulated mud will be discharged, thereby achieving the purpose of dehydration, and the squeezed water will be discharged from the drain hole 312 at the bottom of the dehydration pipe 32 to the outside of the dehydration pipe 32, and when the pushing block 311 squeezes the accumulated mud to a certain extent, the sealing mechanism will automatically release the blockage of the dehydration pipe 32, and at this time, under the push of the pushing block 311, the dehydrated accumulated mud will automatically be discharged from the inside of the dehydration pipe 32 to the inside of the recovery box 5.

[0026] See also Figure 3 and Figure 4 The blocking assembly includes a connecting block 310 fixed on the outer wall of the dehydration pipe 32 and symmetrically distributed. The connecting block 310 is rotatably connected to a blocking plate 34 for blocking the end of the dehydration pipe 32. A baffle 36 is provided on the outside of the dehydration pipe 32. The baffle 36 is connected to the outer wall of the dehydration pipe 32 through a first elastic member 38. A stop plate 33 and a wedge plate 35 are fixedly connected to the bottom of the baffle 36. The stop plate 33 is in contact with the blocking plate 34. The wedge plate 35 penetrates the side wall of the dehydration pipe 32 and is slidably connected to the side wall of the dehydration pipe 32. A guide rod 37 is fixed on the outer wall of the dehydration pipe 32. The guide rod 37 penetrates the baffle 36 and is slidably connected to the baffle 36; When dehydrating the accumulated mud, the push plate 33 squeezes the blocking plate 34 under the action of the baffle plate 36 and the first elastic member 38, and the blocking plate 34 blocks the end of the dehydration pipe 32. The first elastic member 38 can be a spring. At this time, the push block 311 can squeeze the accumulated mud while moving, so that the water inside it can seep out. When the push block 311 squeezes the accumulated mud to a certain extent, the push block 311 begins to squeeze the inclined surface of the wedge plate 35, so that the wedge plate 35 drives the baffle plate 36 to move upward, and the baffle plate 36 drives the push plate 33 The push block 311 moves upward, thereby releasing the squeezing state of the back plate 33 on the sealing plate 34. As the push block 311 continues to move, the push block 311 squeezes the accumulated mud inside the dehydration pipe 32 to the outside of the dehydration pipe 32. When the pushing assembly drives the push block 311 to move in the opposite direction, the push block 311 no longer squeezes the wedge plate 35. The wedge plate 35 and the back plate 33 are automatically reset under the action of the baffle 36 and the first elastic member 38. The back plate 33 squeezes the sealing plate 34 again, so that the sealing plate 34 seals the dehydration pipe 32 again.

[0027] See also Figure 2 and Figure 3The pushing assembly includes a push rod 39 fixedly connected to a push block 311, the push rod 39 passes through the end of the dehydration tube 32 and is slidably connected to the end of the dehydration tube 32, a push plate 313 is fixed to one end of the push rod 39 located outside the dehydration tube 32, and the push plate 313 is connected to the end of the dehydration tube 32 through a second elastic member 314, wherein an extrusion block 315 for extruding the push plate 313 is fixed to the outside of the rotating rod 11; When the rotating rod 11 rotates, it also drives the extrusion block 315 outside it to rotate. When the extrusion block 315 rotates to a certain extent, the extrusion block 315 squeezes the push plate 313, and the push plate 313 drives the push block 311 to squeeze the accumulated mud inside the dewatering pipe 32 through the push rod 39. When the extrusion block 315 no longer squeezes the push plate 313, the push plate 313 automatically resets under the action of the second elastic member 314, and then drives the push block 311 to automatically reset through the push rod 39, wherein the second elastic member 314 can be a spring.

[0028] See also Figure 2 and Figure 6 The crushing mechanism 4 includes a connecting plate 46 arranged below the supporting plate 1, the connecting plate 46 is connected with a vibration assembly, the vibration assembly is used to drive the connecting plate 46 to vibrate up and down, a transmission rod 41 is passed through the inside of the connecting plate 46, the transmission rod 41 is rotatably connected to the connecting plate 46 through a bearing 45, a rotating blade 42 is fixed to the lower end of the outer wall of the transmission rod 41, the lower end of the rotating rod 11 extends into the transmission rod 41 and is slidably connected to the transmission rod 41, a limiting assembly is provided between the rotating rod 11 and the transmission rod 41, the limiting assembly is used to limit the transmission rod 41, so that the transmission rod 41 can rotate with the rotating rod 11; As the rotating rod 11 rotates, the transmission rod 41 is driven to rotate through the limit assembly. The transmission rod 41 drives the rotating blade 42 outside it to rotate, thereby crushing the accumulated mud at the bottom of the oxidation ditch. During the rotation of the transmission rod 41, the connecting plate 46 is driven to vibrate up and down through the vibration assembly. The connecting plate 46 drives the transmission rod 41 to vibrate up and down through the bearing 45, so that the rotating blade 42 can move up and down while rotating, effectively improving the crushing effect of the rotating blade 42 on the accumulated mud.

[0029] See also Figure 6 The limiting assembly includes a limiting block 44 fixed to the outside of the rotating rod 11 and symmetrically distributed, and a limiting groove 43 symmetrically distributed is provided on the inner wall of the transmission rod 41, and the limiting block 44 is located inside the limiting groove 43 and is slidably connected to the limiting groove 43; As the rotating rod 11 rotates, the transmission rod 41 is driven to rotate through the limit block 44 and the limit groove 43, so that the transmission rod 41 can drive the rotating blade 42 to rotate, thereby breaking up the accumulated mud inside the oxidation ditch, effectively ensuring the effect of the mud pump 7 on extracting the accumulated mud inside the oxidation ditch. The setting of the limit block 44 and the limit groove 43 enables the transmission rod 41 to rotate and move up and down outside the rotating rod 11 at the same time.

[0030] See also Figure 2 and Figure 6 The vibration assembly includes a limit rod 48 fixedly connected to the connecting plate 46 and symmetrically distributed, the limit rod 48 penetrates the support plate 1 and is slidably connected to the support plate 1, a third elastic member 47 is provided on the outside of the limit rod 48, and the two ends of the third elastic member 47 are respectively fixedly connected to the connecting plate 46 and the support plate 1, a squeeze ring 49 is fixed on the top of the limit rod 48, and the top of the squeeze ring 49 is undulating, and a fixed plate 410 is fixed on the outside of the rotating rod 11, and an squeeze rod 411 for squeezing the squeeze ring 49 is fixed on the bottom of the fixed plate 410; When the rotating rod 11 rotates, the squeezing rod 411 is driven to make a circular motion through the fixed plate 410. Since the top of the squeezing ring 49 is arranged in an undulating manner, the squeezing degree of the squeezing ring 49 by the squeezing rod 411 will constantly change. When the squeezing degree of the squeezing ring 49 by the squeezing rod 411 increases, the squeezing ring 49 drives the connecting plate 46 to move downward through the limiting rod 48, thereby driving the transmission rod 41 to move upward. When the squeezing degree of the squeezing ring 49 by the squeezing rod 411 decreases, the connecting plate 46 automatically moves upward under the action of the third elastic member 47, thereby driving the transmission rod 41 to move upward. This cycle is repeated, so that the rotating blade 42 can move up and down while rotating, thereby effectively improving the crushing effect of the accumulated mud and ensuring the cleaning efficiency of the accumulated mud.

[0031] See also Figure 5 A guide block 13 is fixed at the bottom of the separation cylinder 2. The guide block 13 is arranged in a truncated cone shape, wherein the rotating rod 11 penetrates the guide body and is rotatably connected to the guide body, and the scraper 9 is slidably connected to the inclined surface of the guide block 13; By setting the guide block 13, the accumulated mud entering the separation cylinder 2 can slide toward the bottom of the separation cylinder 2. At the same time, in cooperation with the scraper 9, it can guide the accumulated mud, so that the accumulated mud can smoothly enter the recovery box 5, thereby avoiding the accumulation of mud inside the separation cylinder 2.

[0032] Working principle: When the device cleans the accumulated mud inside the oxidation ditch, the support plate 1 is driven by the hull or other floating body to move above the water surface inside the oxidation ditch, and then the motor 10 and the mud pump 7 are started. Under the action of the mud pump 7, the accumulated mud and water inside the water body enter the separation cylinder 2 through the mud pumping pipe 6. Since a plurality of water outlets 12 are provided at the bottom of the separation cylinder 2, the accumulated water directly falls on the surface of the support plate 1 through the water outlets 12, and slides down the surface of the support plate 1 to the inside of the oxidation ditch again, and the accumulated mud accumulates inside the separation cylinder 2, thereby separating the accumulated water from the accumulated mud. The purpose of mud cleaning can be achieved without draining the accumulated water inside the oxidation ditch, which effectively improves the cleaning efficiency of the accumulated mud in the oxidation ditch. At the same time, the motor 10 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the transmission rod 41 to rotate through the limit block 44 and the limit groove 43, so that the transmission rod 41 can drive the rotating blade 42 to rotate, so as to crush the accumulated mud inside the oxidation ditch. While the rotating rod 11 rotates, it also drives the extrusion rod 411 to make a circular motion through the fixed plate 410. Since the top of the extrusion ring 49 is arranged in an undulating manner, the degree of extrusion of the extrusion ring 49 by the extrusion rod 411 will constantly change. The extrusion ring 49 drives the connecting plate 46 to move up and down through the limit rod 48. The connecting plate 46 drives the transmission rod 41 to move up and down through the bearing 45, so that the rotating blade 42 can also move up and down while rotating, which effectively improves the crushing effect of the accumulated mud and ensures the cleaning efficiency of the accumulated mud. When the push block 311 is moved, the mud inside the dewatering tube 32 is squeezed out, and the water inside the dewatering tube 32 is effectively discharged.
