Explosion-proof septic tank

Abstract

The invention provides an explosion-proof septic tank 4. Air vents (7) are formed in the upper side of a water passing hole (6) of a separation plate (5) of a septic tank (1), so that the problem that the water passing hole (6) of the septic tank is easily blocked through sludge and liquid manure is full and overflows can be improved; furthermore, the plurality of air vents with the diameter greater than 2cm or more are formed in the edge of a well lid (9) so that air inside and outside the septic tank is convenient to circulate; an air cap (8) is arranged on the well lid (9) of a cleaning well (10), marsh gas in the septic tank can be effectively exhausted and the concentration of the marsh gas in the septic tank can be reduced, so that the problem that people are injured through explosion of the marsh gas of the septic tank can be effectively prevented; and the explosion-proof septic tank is simple in structure, good in utilization effect and extremely prone to implement and popularize.

Description

technical field [0001] The present invention relates to a new explosion-proof septic tank 4 Background technique [0002] The septic tank is a three-format sewage treatment structure composed of the first-level anaerobic chamber, the second-level anaerobic chamber, and the third-level clarification chamber. At present, the interior of the septic tank is mostly divided into three compartments by partitions (partition walls). ), if the septic tank is not cleared in time, when the sludge deposited in the septic tank exceeds the height of the water hole, the sludge will block the water hole, so that the feces in the septic tank cannot flow normally from the outlet of the septic tank Therefore, it is prone to the problem of septic tank clogging and overflowing; in addition, the sludge clogs the water hole on the septic tank partition, which can cause the biogas produced by its anaerobic fermentation to be unable to flow in the three-compartment septic tank. Circulation and accu...

Problems solved by technology

[0004] The present invention is realized like this, as attached figure 1 As shown, it is respectively provided with one or more ventilation holes (7) above the water hole (6) of the septic tank (1) clapboard (5), so that even if the water passing through the middle part of the septic tank clapboard (5) The hole (6) is blocked by sludge, and the feces in the septic tank can still be discharged into the sewer from the water outlet (3) through the air hole (7), which can improve the septic tank water hole (6) that is easily blocked by sludge. In addition, it is provided with a plurality of ventilation holes with a diameter of more than 2cm on the edge of the well cover (9) to facilitate the internal and external air circulation of the septic
