[0002] Anaerobic tank, also known as anaerobic digester, is a device that utilizes anaerobic microorganisms to decompose organic matter under anaerobic conditions. It plays a key role in environmental engineering and waste management, especially for the resource utilization of organic waste. Its working principle is to create an oxygen-deficient environment inside the anaerobic tank, promoting the growth of specific anaerobic bacterial communities. These bacteria can gradually decompose organic matter in wastewater, producing biogas (mainly composed of methane and carbon dioxide) as a byproduct. This process typically consists of four stages: hydrolysis, acidification, acetogenesis, and methanogenesis. It is mainly applied in municipal wastewater treatment plants, agricultural waste treatment (such as livestock manure), and urban organic solid waste treatment, achieving waste reduction and resource recycling.

[0041] Example 1

[0042] like Figure 1 As shown, the main body of an anaerobic tank overflow device is an overflow trough 1; a fixing frame 2 is connected to the side of the overflow trough 1, and the fixing frame 2 installs the overflow trough 1 on the corresponding anaerobic tank; for convenient maintenance and repair of the overflow trough, a top plate 3 is provided on the top of the overflow trough 1, and the top plate can be opened; a feed pipe 4 is connected to the bottom of the overflow trough 1, and the feed pipe 4 conveys the liquid material in the anaerobic tank to the overflow trough 1 by siphon; in order to control the connection between the anaerobic tank and the overflow trough 1, a gate valve 41 is provided on the feed pipe 4; an overflow pipe 6 is connected to the overflow trough 1, and the overflow pipe 6 extends into the overflow trough 1 to a certain height. When the height of the liquid material in the overflow trough 1 exceeds the height of the overflow pipe 6, the liquid material is discharged through the overflow pipe 6; the overflow pipe 6 is prone to accumulating impurities, so a flushing mechanism 5 is installed on the overflow trough 1 to flush the impurities in the overflow pipe 6 and keep the overflow pipe 6 unobstructed.

[0043] like Figure 2As shown, the flushing mechanism 5 comprises: a base 51, a liquid tank 52, a flushing pipe 53, a flushing pump 54, and a flushing port 55. The connection relationship of the above components is as follows: the base 51 is connected with the side wall of the overflow tank 1; the liquid tank 52 is arranged on the base 51; one end of the flushing pipe 53 is connected with the liquid tank 52, and the other end is arranged in the overflow tank 1; the flushing pump 54 is arranged on the flushing pipe 53; the flushing port 55 is arranged in the overflow tank 1 and is connected with the flushing pipe 53 at the other end relative to the liquid tank 52; the flushing port 55 is arranged above the mouth of the overflow pipeline 6; and the liquid tank 52 is a water storage tank. When the overflow pipeline 6 needs to be flushed, the flushing pump 54 is opened, the flushing pump 54 delivers the water in the water storage tank to the flushing port 55 through the flushing pipe 53, the flushing port sprays water to flush the overflow pipeline 6, and impurities are discharged through the overflow pipeline 6 after being flushed.

[0044] As shown in Figure 1 , 4 , the first mounting block 31 is connected with the top of one side of the overflow tank 1, the hinge 32 is connected with the first mounting block 31, and the hinge 32 is connected with the top plate 3. Through the above connection relationship, the rotating connection of the top plate 3 and the overflow tank 1 is realized. The lock ring 35 is arranged on the outside of the overflow tank 1 relative to the other side of the first mounting block 31, the lock plate 36 is rotatably connected with the top plate 3, and the lock ring 35 is detachably connected with the lock plate 36. Through the above connection relationship, the detachable connection of the top plate 3 and the overflow tank 1 is realized. In order to prevent the biogas in the anaerobic tank from escaping from the top plate 3 during the overflow process, the second mounting block 34 is arranged on the overflow tank 1 relative to the other side of the first mounting block 31, the sealing block 37 is arranged on the second mounting block 34, and the top plate 3 is connected with the overflow tank 1 through the sealing block 37 to prevent the leakage of biogas and ensure the safety of production.

[0046] The working process of the embodiment is as follows:

[0047] When the overflow tank 1 is maintained and repaired, first, the gate valve 41 is closed to prevent the biogas in the anaerobic tank from entering the overflow tank 1 through the feed pipe 4; then, the connection between the lock plate 36 and the lock ring 35 is released, and the top plate 3 is opened; then, the overflow tank 1 is maintained and repaired; then, the top plate 3 is closed, and the lock plate 36 is connected with the lock ring 35.

[0048] When the overflow pipeline 6 is flushed, the flushing pump 54 is opened, the flushing pump 54 delivers the water in the water storage tank to the flushing port 55 through the flushing pipe 53, the flushing port sprays water to flush the overflow pipeline 6, and impurities are discharged through the overflow pipeline 6 after being flushed.

[0049] Example 2

[0050] The overflow pipe 6 is easily blocked by the crystalline struvite, as shown in Figure 3 The liquid tank 52 is a medicine tank, and the liquid in the medicine tank can dissolve the struvite.

[0051] As shown in Figure 3 In order to improve the dissolution rate of the struvite, the overflow pipe 6 is divided into two or more sections, and a valve 62 is connected between each section of the overflow pipe 6. By closing the valve 62 below the blocked position, the overflow pipe 6 can be unblocked in a targeted manner.

[0052] Workflow of the embodiment:

[0053] First, determine the position of the crystalline struvite blocking the overflow pipe 6; then, close the valve 62 below the blocked position and open all valves 62 above the blocked position; then, start the flushing pump 54, which delivers the liquid in the medicine tank to the flushing port 55 through the flushing pipe 53, and the flushing port 55 sprays the liquid into the overflow pipe 6; then, after a period of time, the crystalline struvite is dissolved; then, open all valves 62, and the dissolved struvite is discharged through the overflow pipe 6.
