Description

Technical Field

[0001] This utility model relates to the field of biochemical pond sludge treatment technology, specifically a sludge flushing device for biochemical pond sludge treatment. Background Technology

[0002] The A / A / O process, also known as the A2 / O process, is a common bioreactor process used in wastewater treatment. It aims to degrade and remove some recalcitrant organic matter in wastewater through anaerobic processes, thereby improving the wastewater's biodegradability and providing a suitable carbon source for the subsequent anoxic stage of denitrification. Ultimately, it achieves efficient removal of COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), N, and P. It is mainly used for secondary or tertiary wastewater treatment, as well as reclaimed water reuse, and has good nitrogen and phosphorus removal effects. However, as a crucial part of wastewater treatment, the sludge floating phenomenon in bioreactors is becoming increasingly serious. This is mainly due to the abnormal life activities of microorganisms in the activated sludge of the reactor. For example, the sludge may age. If aged and dead sludge is not discharged in time, it will easily float and accumulate in the dead corners of aeration, affecting the treatment effect of the process. The most obvious characteristic is that when the sludge accumulates on the surface of the biological treatment tank for a long time, it will cause agglomeration and mineralization, leading to sludge loss. Covering also affects contact with air and dissolved oxygen, so sludge treatment is required. However, current technology is not convenient for automatically and uniformly dispersing the floating sludge in the biological treatment tank, thus affecting the biological treatment tank to achieve its maximum efficiency.

[0003] To address the aforementioned problems, a flushing device for treating floating sludge in biological treatment ponds is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a flushing device for treating floating sludge in biological treatment ponds, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flushing device for treating floating sludge in a biological treatment tank, comprising two electric slide rails, each with a sliding seat slidably mounted on its top, an installation strip fixedly mounted between the two sliding seats, a water pump fixedly mounted at the middle of the top of the installation strip, an outlet pipe fixedly connected to the outlet end of the water pump, a diversion pipe fixedly connected to the bottom end of the outlet pipe, a plurality of evenly distributed high-pressure nozzles fixedly connected to the bottom end of the diversion pipe, an inlet pipe fixedly connected to the inlet end of the water pump, a filter tank fixedly connected to the end of the inlet pipe away from the water pump, a sealing cap engaged at the end of the filter tank away from the inlet pipe, a conduit fixedly connected to the middle of the sealing cap, an annular mounting seat fixedly mounted inside the filter tank, a fixing ring engaged at one end of the annular mounting seat, and a first filter screen and a second filter screen fixedly connected to the two ends of the inner side of the fixing ring, respectively.

[0006] The two connecting slots engage with the two connecting posts to initially limit the positioning of the fixing ring. The two limiting springs engage with the two limiting grooves to further limit the positioning of the fixing ring, thereby ensuring the stable operation of the first and second filters. The coordinated arrangement of the first and second filters facilitates the filtration of water entering the water pump, thus preventing the water pump and pipes from being blocked by impurities. The water pump guides the water into the outlet pipe, then into the diversion pipe, and then sprays the water evenly through several high-pressure nozzles. Simultaneously, two electric slide rails drive two sliding seats to move synchronously, thereby driving the installation strip to move stably, which in turn drives the water pump and other structures to move stably, thus facilitating the all-round and uniform flushing of the floating sludge in the biological treatment tank.

[0007] Preferably, two connecting slots are provided at the connection between the annular mounting base and the fixed ring, and two connecting posts are fixedly provided at the connection between the fixed ring and the annular mounting base. The two connecting slots are respectively engaged with the two connecting posts, and the fixed ring is initially limited by the limiting engagement of the two connecting slots with the two connecting posts.

[0008] Preferably, each of the two connecting pins has a mounting groove on one side, and a limiting spring is fixedly installed inside each of the two mounting grooves. A limiting groove is also provided on one side of the inner wall of each of the two connecting pins. The two limiting springs are respectively engaged with the two limiting grooves. The engagement of the two limiting springs with the two limiting grooves facilitates further limiting of the fixing ring.

[0009] Preferably, a sealing gasket is fixedly provided at the connection between the sealing cover and the filter canister, which can improve the sealing performance of the filter canister.

[0010] Preferably, a sealing ring is fixedly provided at the end of the fixing ring away from the annular mounting seat, which can further improve the sealing performance.

[0011] Preferably, two fixing members are fixedly provided on the outer side of each of the two electric slide rails, and fixing holes are provided in the middle of each of the four fixing members. The combination of the four fixing members and the four fixing holes facilitates the fixed installation of the device.

[0012] Preferably, two fixing strips are fixedly provided between the installation strip and the diversion pipe, which facilitates the fixed installation of the diversion pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the two connecting slots engage with the two connecting posts to facilitate the initial positioning of the fixing ring, and the two limiting springs engage with the two limiting grooves to further position the fixing ring, thereby ensuring the stable operation of the first and second filters. The coordinated arrangement of the first and second filters facilitates the filtration of water entering the water pump, thus preventing the water pump and pipes from being blocked by impurities. The water pump guides the water into the outlet pipe, then into the diversion pipe, and sprays the water evenly through several high-pressure nozzles. At the same time, two electric slide rails drive two sliding seats to move synchronously, thereby driving the installation strip to move stably, which in turn drives the water pump and other structures to move stably, thus facilitating the all-round and uniform flushing treatment of the floating sludge in the biological treatment tank.
