Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a sludge removal device for wastewater treatment. Background Technology

[0002] As a core unit of the wastewater treatment process, the sludge removal system plays a crucial role in promptly removing sludge deposited in structures such as sedimentation tanks and reaction tanks. Its operational efficiency directly affects the effluent quality, operating costs, and the difficulty of subsequent sludge disposal at wastewater treatment plants.

[0003] In traditional wastewater treatment processes, the core design focus of sludge removal devices is on the efficient discharge of sludge. Mainstream technologies include mechanical scraping and suction sludge equipment, air-lift sludge removal devices, and sludge valve systems. Mechanical scraping and suction sludge equipment collects sludge through scraper pushing or negative pressure suction. While it can cover different tank types, the discharged sludge generally has a water content exceeding 97%, exhibiting a fluid state. This necessitates subsequent independent thickening tanks, filter presses, and other equipment for solid-liquid separation. This not only increases infrastructure investment and land area but also raises maintenance costs due to pipeline blockages during sludge transportation, further impacting wastewater treatment.

[0004] Therefore, this utility model provides a sludge removal device for sewage treatment. Utility Model Content

The conveying inclined plates have built-in torsion springs, which can keep the conveying inclined plates at an inclined angle. The combined use of the rotating disk, connecting block and reduction motor can slowly convey sludge by rotation. The inclined plates can prevent the sludge from violently shaking and dispersing during rotation by their inclined angle.

[0007] Preferably, the material guiding mechanism includes an inclined plate, a silicone scraper, and an intercepting plate.

The conveying pipe is connected to the side of the treatment tank surface near the inclined plate. The end of the conveying pipe away from the treatment tank is fixedly installed with the discharge pump. The output end of the discharge pump is fixedly installed with the discharge pipe.

The bottom of the surface of the storage tank is connected to the drain outlet. The top of the storage tank is rotatably installed with the sealed door. In this scheme, the combined use of the storage tank, the drain outlet, and the sealed door allows the discharged sludge to be temporarily stored in the storage tank, thereby enabling the next process to proceed.

[0010] Preferably, the separation component includes a drive motor and a separation net. The drive motor is fixedly installed at the bottom of the storage tank, and the separation net is rotatably installed at the bottom of the inner wall of the storage tank. The output end of the drive motor is fixedly connected to the separation net. In this scheme, the combined use of the drive motor and the separation net can use the centrifugal force generated by rotation to throw out the water in the sludge, so that solid-liquid separation can be carried out normally.

[0011] Preferably, both the conveying pipe and the drain outlet are equipped with solenoid valves. In this design, the solenoid valves enable the user to precisely control the discharge status of the conveying pipe and the drain outlet, making mud discharge more accurate and efficient.

The output end of the reduction motor 34 is fixedly mounted to the connecting block 32. The connecting block 32 is fixedly connected to the rotating disk 31. Several sets of conveying inclined plates 33 are arranged in a ring and rotated on the top of the rotating disk 31. The conveying inclined plate 33 has a torsion spring built in it, which can keep the conveying inclined plate 33 at the same tilt angle. The material guiding mechanism 4 includes an inclined plate 41, a silicone scraper 42, and a intercepting plate 43. The inclined plate 41 is fixedly installed on one side of the bottom of the inner wall of the treatment tank 8. The bottom of the inclined plate 41 is fixedly installed with the silicone scraper 42, and the top of the inclined plate 41 is fixedly installed with the intercepting plate 43. The material conveying mechanism 5 includes a material conveying pipe 51, a discharge pump 52, and a discharge pipe 53. The material conveying pipe 51 is connected to the side of the surface of the treatment tank 8 near the inclined plate 41. The end of the material conveying pipe 51 away from the treatment tank 8 is fixedly installed with the discharge pump 52, and the output end of the discharge pump 52 is fixedly installed with the discharge pipe 53. The storage machine... The structure 6 includes a storage tank 61, a drain outlet 62, and a sealed door 63. The storage tank 61 is fixedly installed on one side of the top of the base plate 1. The bottom of the surface of the storage tank 61 is connected to the drain outlet 62. The top of the storage tank 61 is rotatably installed with the sealed door 63. The separation component 7 includes a drive motor 71 and a separation net 72. The drive motor 71 is fixedly installed at the bottom of the storage tank 61. The separation net 72 is rotatably installed at the bottom of the inner wall of the storage tank 61. The output end of the drive motor 71 is fixedly connected to the separation net 72. Both the conveying pipe 51 and the drain outlet 62 have built-in solenoid valves.

[0026] like Figures 1 to 5As shown, the combined use of the rotating disk 31, connecting block 32, and reduction motor 34 enables the slow conveying of sludge through rotation. The conveying inclined plate 33, through its tilt angle, prevents the sludge from violently shaking and dispersing during rotation. The combined use of the inclined plate 41, silicone scraper 42, and intercepting plate 43 continuously scrapes the sludge on the surface of the rotating disk 31 during its rotation and conveys the sludge outwards through its tilt angle. The combined use of the conveying pipe 51, discharge pump 52, and discharge pipe 53 enables the conveying of sludge from the inclined plate 41 to... The sludge is assisted in being extracted and transported to the separation net 72 for storage.

The solenoid valve allows the user to precisely control the discharge status of the conveying pipe 51 and the drain outlet 62, making the sludge discharge more accurate and efficient.

[0027] Working principle: During operation, the base plate 1 is first placed on a flat surface. Then, wastewater is injected into the treatment tank 8 for sedimentation. The settled sludge adheres to the surface of the rotating disc 31. At this time, the user needs to start the reduction motor 34 to drive the connecting block 32 and the rotating disc 31 to rotate. The rotation of the rotating disc 31 will cause the sludge to move slowly. As the rotating disc 31 continues to rotate, the silicone scraper 42 and the inclined plate 41 will continuously scrape the sludge on the surface of the rotating disc 31 and convey it into the conveying pipe 51. When the conveying inclined plate 33 moves to the silicone scraper 42, the conveying inclined plate 33 will be affected by the silicone scraper 42. The scraper 42 rotates due to the squeezing and remains flush with the rotating disk 31 to allow the silicone scraper 42 to pass through normally. When the sludge accumulates in the conveying pipe 51, the discharge pump 52 is started to draw out the sludge in the conveying pipe 51 and discharge it into the storage tank 61 through the discharge pipe 53. Then the sludge will enter the separation net 72. At that time, the user needs to start the drive motor 71 to drive the separation net 72 to rotate and generate centrifugal force to throw out the water in the sludge and discharge it through the drain outlet 62. Then the user opens the sealed door 63 and cleans the sludge in the separation net 72.
