Description

Technical Field

[0001] This utility model discloses a sludge treatment device, belonging to the technical field of sewage treatment equipment, specifically relating to a sludge treatment device for sewage treatment. Background Technology

[0002] Sludge treatment equipment for wastewater treatment primarily uses physical or chemical methods to dewater and utilize sludge. Its core functions include reducing sludge moisture content, lowering treatment costs, and promoting resource recovery. The role of sludge treatment equipment is to reduce sludge moisture content, using technologies such as thickening and dewatering to lower it to 60%-90%, thus reducing subsequent transportation and processing costs. For example, belt filter presses can reduce moisture content to 75%-85%, while plate and frame filter presses can reduce it to 60%-70%.

[0003] Traditional sludge treatment equipment discharges sludge from the bottom, but because sludge has a certain degree of adhesion, a small amount of sludge will stick to the tank body, which will cause blockage of the sludge discharge pipe over time. Utility Model Content

[0004] Purpose of the utility model: To provide a sludge treatment device for sewage treatment, and to solve the problems mentioned above.

[0005] Technical solution: A sludge treatment device for sewage treatment, the sludge treatment device comprising: a treatment tank, an inlet pipe, a sludge outlet pipe, an outlet pipe, a sludge outlet pipe, and a sludge scraping assembly;

[0006] In a further embodiment, the sludge scraping assembly is installed inside the treatment tank, which is provided with a guide wall and a scum baffle. A water collection trough is formed between the guide wall and the inner wall of the treatment tank. The scum baffle is connected to the guide wall, forming a main outlet channel and an overflow channel between them. The inlet pipe is installed on one side of the treatment tank and connects to the main water collection trough. The sludge discharge pipe is installed at the bottom of the treatment tank and connects to the inside of the tank. The outlet pipe is installed on one side of the treatment tank and connects to the main outlet channel. The scum discharge pipe is installed on one side of the treatment tank and connects to the overflow channel.

[0007] In a further embodiment, the sludge scraping assembly includes: a transmission machine, a central frame, a flow stabilizer, a scum scraper, a scum rake, a scraper frame, and small scrapers.

[0008] In a further embodiment, the bottom of the water collection trough is provided with a water inlet hole.

[0009] In a further embodiment, the central frame is mounted on the treatment tank via a support beam, the transmission is mounted on the central frame to drive the central frame to rotate, the flow stabilizer is sleeved on the central frame to rotate with the central frame, the scraper frame is sleeved on the central frame to rotate with the central frame, the scum rake is sleeved on the flow stabilizer, the scum rake is connected to both the scum scraper and the scraper frame, and the small scraper is fixedly installed at the bottom of the central frame.

[0010] In a further embodiment, a sludge discharge trough is formed at the bottom center of the treatment tank, and the sludge discharge pipe is connected to the sludge discharge trough.

[0011] In a further embodiment, the height of the overflow channel is higher than the height of the main outlet channel.

[0012] Beneficial effects: This utility model has a scraper frame on the central frame and a small scraper at the bottom, which can clean the sludge inside the treatment tank and the sludge discharge trough. At the same time, the small scraper can clean the sludge on the inner wall of the sludge discharge trough, thereby preventing sludge from sticking and further preventing sludge blockage.

[0020] A sludge treatment device for sewage treatment includes: a treatment tank 1, an inlet pipe 2, a sludge outlet pipe 3, an outlet pipe 4, a slag outlet pipe 5, and a sludge scraping assembly 6.

[0021] In one embodiment, such as Figures 1 to 3 As shown, the sludge scraping assembly 6 is installed inside the treatment tank 1. The treatment tank 1 is provided with a guide wall 16 and a scum baffle 17. A water collection trough 18 is formed between the guide wall 16 and the inner wall of the treatment tank 1. The scum baffle 17 is connected to the guide wall 16 and forms a main outlet channel 19 and an overflow channel 20 between them. The inlet pipe 2 is installed on one side of the treatment tank 1 and is connected to the main water collection trough 18. The sludge discharge pipe 3 is installed at the bottom of the treatment tank 1 and is connected to the inside of the tank. The outlet pipe 4 is installed on one side of the treatment tank 1 and is connected to the main outlet channel 19. The scum discharge pipe 5 is installed on one side of the treatment tank 1 and is connected to the overflow channel 20.

[0022] In one embodiment, such as Figures 1 to 3 As shown, the sludge scraping assembly 6 includes: a transmission machine 7, a central frame 8, a flow stabilizer 9, a scum scraper 10, a scum rake 11, a scraper frame 12, and a small scraper 13.

[0023] In one embodiment, such as Figures 1 to 3 As shown, the bottom of the water collection tank 18 is provided with a water inlet hole 14.

[0024] In one embodiment, such as Figures 1 to 3 As shown, the central frame 8 is mounted on the treatment tank 1 via a support beam. The transmission machine 7 is mounted on the central frame 8 to drive the central frame 8 to rotate. The flow stabilizer 9 is sleeved on the central frame 8 to rotate with the central frame 8. The scraper frame 12 is sleeved on the central frame 8 to rotate with the central frame 8. The scum rake 11 is sleeved on the flow stabilizer 9. The scum rake 11 is connected to both the scum scraper 10 and the scraper frame 12. The small scraper 13 is fixedly installed at the bottom of the central frame 8.

[0025] In one embodiment, such as Figures 1 to 3 As shown, a sludge discharge trough 15 is formed at the bottom center of the treatment tank 1, and the sludge discharge pipe 3 is connected to the sludge discharge trough 15.

[0026] In one embodiment, such as Figures 1 to 3 As shown, the height of the overflow channel 20 is higher than the height of the main outlet channel 19.

[0027] Working principle: When this utility model is in operation, sewage is first introduced into the treatment tank 1 through the inlet pipe 2. Then, the transmission 7 of the sludge scraping assembly 6 works, thereby driving the central frame 8 to rotate, which in turn drives the scraper frame 12 to rotate, which in turn drives the scum scraper 10 to rotate. At the same time, the scum rake 11 draws the sludge into the overflow. Sewage enters the main outlet channel 19 and flows out through the outlet pipe 4. Scum flows out through the scum outlet pipe 5, and sludge flows into the sludge outlet trough 15 and flows out through the sludge outlet pipe 3.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
