Description

Technical Field

[0001] This invention relates to the technical field of sewage treatment equipment, specifically a sewage treatment tank that improves sludge scraping efficiency. Background Technology

[0002] Sedimentation is often used in wastewater treatment. Sedimentation can remove solid impurities such as sludge from wastewater. However, the drawback of sedimentation is that the sludge that settles at the bottom of the container is often difficult to clean.

[0003] According to patent application CN201820797585.8, a wastewater treatment settling tank includes a tank body. A treatment pipe is fixed in the center of the tank body's inner cavity. A partition is slidably fitted onto the outer side of the treatment pipe, with its edge tightly fitted against the inner wall of the tank body. A collar is fixed to the upper part of the partition and slidably fitted onto the outer side of the treatment pipe. A connecting rod is welded to the upper end of the collar, and a tank lid is placed on the upper end of the connecting rod. A handle is welded to the upper end of the tank lid. An arc-shaped groove is formed on the surface of the partition, and second drainage holes are evenly distributed within the groove. The outer shell of the tank body is composed of two layers, with a water storage cavity between the two layers. A third drainage hole is formed at the lower end of the inner wall of the tank body, connecting the treatment pipe and the water storage cavity. This product can quickly achieve mud-water separation, providing a certain degree of purification, and allows for convenient removal of mud and sand.

[0004] The product in the aforementioned patent can achieve mud-water separation and can easily remove mud and sand, but a large amount of mud and sand may settle at the bottom of the barrel, resulting in slow cleaning speed and difficulty in removing the adhering substances on the barrel wall.

[0039] Furthermore, after the sludge is loosened, the drive motor 241 stops working, the electric cylinder 222 drives the scraper pipe 22 to move down, and the scraper ring 221 at the bottom of the scraper pipe 22 scrapes the loosened sludge onto the sludge plate 31.

[0040] Please refer to the appendix carefully. Figure 2 , 4As shown in Figures 5 and 6, in another preferred embodiment of the present invention, the bottom sludge scraping device 30 includes a sludge plate 31 connected to the inner wall of the bucket body 10, a lifting plate 32 disposed at the bottom of the sludge plate 31, a sludge separating frame 33 disposed at the upper part of the lifting plate 32 and extending through the sludge plate 31 to the upper part, a lower lifting and rotating component 36, a sludge-dispensing component 34 disposed on the lifting and rotating component 36, a plurality of sludge dilution components 37 disposed on the outer wall of the bucket body 10, and a plurality of sludge suction components 35. When cleaning the sludge at the bottom of the bucket, the lifting plate 31... 2. The sludge moves downward and is driven to move down by the sludge separating frame 33. The lifting and rotating component 36 drives the sludge-pushing component 34 to rotate, so as to push the sludge on the sludge plate 31 and the lifting plate 32 to the suction component 35. The lifting and rotating component 36 includes a positioning frame 361 located at the bottom of the barrel 10. Both ends of the positioning frame 361 pass through the bottom of the barrel 10 and are connected to the bottom of the lifting plate 32. The positioning frame 362 is located at the bottom of the positioning frame 361. The output ends of the two hydraulic cylinders 362 pass through the positioning frame 361 and are connected to the bottom of the barrel 10. The sludge-pushing component 34 moves down and is driven to move down by the sludge separating frame 33. The lifting and rotating component 36 drives the sludge-pushing component 34 to rotate, so as to push the sludge on the sludge plate 31 and the lifting plate 32 to the suction component 35. The mud-dispensing component 34 includes a drive motor 341 connected to the bottom of the positioning frame 361, a drive shaft 342 located at the output end of the drive motor 341, and two mud-dispensing frames 343 mounted on the drive shaft 342. The drive shaft 342 sequentially passes through the positioning frame 361, the barrel 10, the lifting plate 32, and the mud-dispensing frame 33. One mud-dispensing frame 343 is located on the upper surface of the lifting plate 32, and the other mud-dispensing frame 343 is located on the upper surface of the mud-dispensing frame 33. The sludge suction component 35 includes a suction pipe 351 with one end penetrating through the outer wall of the barrel 10. The bottom of the suction pipe 351 is equipped with a drive cylinder 352 for moving the suction pipe 351. The output end of the drive cylinder 352 is connected to the outer wall of the barrel 10. The sludge dilution component 37 includes a dilution pipe 371 disposed on the outer wall of the barrel 10. The dilution pipe 371 is horizontally arranged and is connected to the tangent of the outer wall of the barrel 10. The sludge separating frame 33 is cross-shaped.

The outer wall of the sludge separating frame 33 is provided with a rubber gasket 332 for sealing between the sludge separating frame 33 and the sludge plate 31.

[0041] It should be noted that in this embodiment, when cleaning the bottom sludge, the hydraulic cylinder 362 drives the positioning frame 361 and the lifting plate 32 to move down. During the downward movement of the lifting plate 32, the sludge on the sludge plate 31 is moved down through the sludge separating frame 33. At this time, the bottom sludge is divided into two parts, which makes it easier to process.

[0042] Furthermore, the dilution pipe 371 can be connected to a water source, and water enters along the tangential direction of the outer wall of the barrel 10, which easily generates swirling flow, which can dilute the sludge while facilitating the loosening of the sludge.

[0043] Furthermore, the drive motor 341 is turned on, and the output end of the drive motor 341 drives the drive shaft 342 to rotate. The drive shaft 342 drives the sludge-removing frame 343 to rotate, and the sludge-removing frame 343 removes the sludge.

[0044] Furthermore, the drive cylinder 352 drives the suction pipe 351 to move into the barrel 10, and the suction pipe 351 sucks out the sludge that has been raised, thus completing the sludge scraping and sewage discharge.

[0045] The specific process of this invention is as follows:

[0046] Wastewater can be added through the water inlet end at the top of the water inlet cover 11. The wastewater settles inside the tank 10. After settling, it is discharged through the water outlet on the outer wall of the tank 10. At this time, there is sludge on the inner wall and bottom of the tank 10. When the drive pipe 21 rotates, the scraper 231 moves relative to the drive pipe 21. The scraper 231 scrapes up the sludge, and the suction pipe 232 sucks up the scraped sludge, thus completing the cleaning of the sludge on the inner wall of the drive pipe 21.

[0047] When the drive motor 241 is turned on, the output of the drive motor 241 drives the first gear disk 242 to rotate. The first gear disk 242 and the second gear disk 243 cooperate to drive the drive tube 21 to rotate.

[0048] When the drive tube 21 rotates, it drives the loosening rod 253 to move on the inner wall of the barrel 10, and the loosening rod 253 loosens the sludge on the inner wall of the barrel 10.

[0049] After the sludge is loosened, the drive motor 241 stops working, the electric cylinder 222 drives the scraper pipe 22 to move down, and the scraper ring 221 at the bottom of the scraper pipe 22 scrapes the loosened sludge onto the sludge plate 31.

[0050] When cleaning the bottom sludge, the hydraulic cylinder 362 drives the positioning frame 361 and the lifting plate 32 to move down. During the downward movement of the lifting plate 32, the sludge on the sludge plate 31 is moved down through the sludge separating frame 33. At this time, the bottom sludge is divided into two parts, which makes it easier to process.

[0051] The dilution pipe 371 can be connected to a water source, and water enters along the tangential direction of the outer wall of the barrel 10, which easily generates swirling flow, which can dilute the sludge while facilitating the loosening of the sludge.

[0052] When the drive motor 341 is turned on, the output end of the drive motor 341 drives the drive shaft 342 to rotate, the drive shaft 342 drives the mud-removing frame 343 to rotate, and the mud-removing frame 343 removes the sludge.

[0053] The drive cylinder 352 drives the suction pipe 351 to move into the barrel 10, and the suction pipe 351 sucks out the sludge that has been raised, thus completing the sludge scraping and sewage discharge.
