Description

Technical Field

[0001] The utility model relates to an ecological management device, in particular to an ex situ ecological management device for two tail water pools of an aquaculture pond and an MBR membrane bioreactor, belonging to the technical field of ecological management devices. Background Art

[0002] The use of a cleaning mechanism in the tail water pools of the aquaculture pond and the MBR membrane bioreactor ectopic ecological management device is one of the links. In the prior art, a water conservancy project dredging device is disclosed in the utility model with application number 202322763048.5. In order to solve the problem that the dredging position adjustment is unchanged and foreign objects such as aquatic plants and branches mixed in the silt easily clog the silt conveying pipeline, thereby affecting the dredging efficiency to a certain extent, a servo motor is used to drive the fixed rod to rotate, and then the bevel gear A outside the fixed rod drives the bevel gear B to rotate, and then the bevel gear B drives the driving screw to rotate, and then the transmission rod outside the driving screw drives the connecting frame to rotate. Move, and then the conveying pipe in the connecting frame drives the fixed cover to move, so that the fixed cover enters the inside of the silt, and then the impeller in the pump body outside the box frame rotates at high speed, and then the silt enters the conveying pipe through the fixed cover, and then the silt is conveyed to the box frame through the connection on one side of the pump body, so as to facilitate the cleaning of silt at different positions and improve the efficiency of dredging of water conservancy projects. When the silt enters the fixed cover, the drive motor A and the drive motor B in the fixed cover respectively drive the drive rod A and the drive rod B to rotate, and then the blades outside the drive rod A and the drive rod B stir the silt, so as to facilitate the crushing of foreign matter in the silt and avoid blockage of the conveying pipe for conveying silt.

[0003] Similar to the above application, there are still some deficiencies:

[0004] When handling relatively dry and hard sludge, it is impossible to break up and soften the sludge. It is difficult for the slurry extraction pipe to penetrate deep into the sludge, making it inconvenient to extract the sludge. In the extraction process, although the pump has the function of crushing foreign matter, due to the open design of the bottom of the fixed cover, foreign matter cannot be crushed multiple times inside the fixed cover. Foreign matter in the sludge cannot be effectively processed, which can easily cause blockage of the pump body and affect the continuous use of the device.

[0005] For this purpose, two tailwater pools of aquaculture ponds and an MBR membrane bioreactor ex situ ecological management device are designed to optimize the above problems. Utility Model Content

At the same time, during the slurry extraction process, the scraper can be used to clean the surface of the filter cylinder, effectively avoiding the clogging of the filter cylinder by debris. In addition, it is used in conjunction with a high-pressure water pump, an annular coil and a high-pressure nozzle to soften the mud, ensure the effect of mud extraction, and have higher practicality.

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides an ex situ ecological management device for two tail water pools of aquaculture ponds and an MBR membrane bioreactor, including a storage box 1 for storing mud, a mud pump 2 for extracting mud, and a slurry pumping pipe 8 that penetrates into the mud and is connected to the input end of the mud pump 2. A filter screen cylinder 9 is fixed to the bottom end of the slurry pumping pipe 8. The filter screen cylinder 9 is made of metal and has strong hardness. A breaking motor 10 is installed at the top end of the slurry pumping pipe 8. A rotating shaft 11 is installed at the output end of the breaking motor 10. The rotating shaft 11 passes through the slurry pumping pipe 8 and the filter screen cylinder 9 and extends to the bottom end of the filter screen cylinder 9. A cone head 12 that fits with the bottom end of the filter screen cylinder 9 is fixed to the bottom end of the rotating shaft 11. A scraper 13 is evenly fixed on the outside of the top end of the cone head 12. The scraper 13 is fitted on the outside of the filter screen cylinder 9. A stirring rod 14 is evenly fixed on the outside of the scraper 13. A lifting mechanism for controlling the insertion depth of the slurry pumping pipe 8 is provided on the outside of the storage box 1, and a mud softening mechanism is installed on the top of the outside of the slurry pumping pipe 8.

[0025] The overall working principle: when in use, the device is moved to the river channel to be dredged, and then the lifting mechanism is used to control the slurry suction pipe 8 to be inserted into the interior of the mud. If the mud surface is relatively hard, the breaking motor 10 is started to drive the shaft 11 to rotate, and the shaft 11 drives the cone head 12 and the stirring rod 14 to rotate, inserting into the interior of the mud and breaking up the mud. After the filter cylinder 9 is completely inserted into the interior of the mud, the mud pump 2 is started to extract the mud into the interior of the storage box 1. If the mud is relatively viscous, the mud softening mechanism can be used to flush the mud with water for extraction operation. During the extraction process, the filter cylinder 9 is used to filter out debris. In order to avoid clogging of the filter cylinder 9, the start-up of the breaking motor 10 can be continuously controlled to perform mud breaking operations. At the same time, when the scraper 13 rotates, it can also clean up the debris adhering to the surface of the filter cylinder 9 to ensure continuous extraction of silt.

[0026] In this embodiment, the lifting mechanism includes a fixed frame 3, a cylinder 4, a collar 5, a delivery pipe 6 and a rubber telescopic tube 7. The fixed frame 3 is fixed at the end of the storage box 1, and the cylinder 4 is vertically installed on the outside of the fixed frame 3. The output end of the cylinder 4 is fixed with a collar 5, and the inside of the collar 5 is fixed with a delivery pipe 6. One end of the delivery pipe 6 is connected to the inside of the slurry suction pipe 8, and a rubber telescopic tube 7 is provided between the other end of the delivery pipe 6 and the input end of the mud pump 2.

[0027] Local working principle: During use, by controlling the start of the cylinder 4, the conveying pipe 6 can be driven to move up and down. The conveying pipe 6 is a metal hard pipe with high hardness, which can drive the slurry extraction pipe 8 to move up and down, and control the extraction depth during the slurry extraction process.

[0028] In this embodiment, the mud softening mechanism includes a high-pressure water pump 15, an annular coil 16 and a high-pressure nozzle 17. The high-pressure water pump 15 is installed on the top of the fixed frame 3, the annular coil 16 is fixed at the top of the outer side of the slurry suction pipe 8, and the high-pressure nozzle 17 is evenly installed on the bottom of the annular coil 16. The output end of the high-pressure water pump 15 is connected to the inside of the annular coil 16 through a pipeline.

[0029] Partial working principle: When the viscosity of the mud is high, the input end of the high-pressure water pump 15 is connected to a water pipe, water is drawn from the source and then sprayed from the high-pressure nozzle 17, impacting the surface of the mud to dilute and soften the mud.

[0030] In this embodiment, the bottom ends of the high-pressure nozzles 17 are all inclined toward the outside of the slurry suction pipe 8, and the high-pressure nozzles 17 are distributed in a ring array.

[0031] Local working principle: By using multiple groups of high-pressure nozzles 17, it is possible to ensure that the mud around the slurry extraction pipe 8 is completely diluted for extraction.

[0032] In this embodiment, a rubber strip is fixed to the inner side of the scraper 13 along the length direction, and the rubber strip is attached to the surface of the filter screen cylinder 9.

[0033] Partial working principle: The use of the rubber strip can ensure that the scraper 13 and the filter screen cylinder 9 are tightly fitted together, thereby ensuring the cleaning effect of the filter screen cylinder 9.

[0034] In this embodiment, a spiral blade 18 is installed on the outer side of the rotating shaft 11 , and the spiral blade 18 is located inside the slurry suction pipe 8 and the filter screen cylinder 9 .

[0035] Partial working principle: During the process of extracting mud, the rotating shaft 11 drives the spiral blade 18 to rotate, which can transport the mud upward to facilitate the extraction of the mud.

[0036] In this embodiment, fins 19 are evenly arranged in an annular array on the outer side of the cone head 12 , and the fins 19 are perpendicular to the side of the cone head 12 .

[0037] Partial working principle: When the fins 18 rotate with the cone head 12, they can improve the penetration effect of the mud so as to filter the mesh cylinder 9 deeper.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
