Description

Technical Field

[0001] This utility model relates to the field of septic tank technology, specifically a high-strength explosion-proof septic tank. Background Technology

[0002] A septic tank is a treatment facility that uses sedimentation and anaerobic fermentation to remove suspended organic matter from domestic sewage. It is a primary and transitional sewage treatment structure that plays an important role in daily life. However, septic tanks also pose a risk of explosion, so they need to be explosion-proofed.

[0003] A search revealed a Chinese patent publication number, CN221117266U, which discloses a high-strength explosion-proof septic tank. The tank includes a main body and an input mechanism, with the input mechanism located above the main body. The main body comprises a fixed outer shell, a fixed base plate, a septic tank, and a protective layer. The fixed base plate is fixedly installed at the lower end of the fixed outer shell, and the septic tank is fixedly installed at the inner end of the protective layer. The protective layer is also fixedly installed at the inner end of the fixed outer shell. By installing a pressure-reducing component, the pressure inside the septic tank can be monitored in real time for safe observation. Furthermore, when the internal pressure reaches a certain value, it automatically releases air to reduce the pressure, making the device safer.

[0004] Although the aforementioned patent can automatically vent and reduce pressure, the device still has the following problems: During the use of the device, since the staff needs to put the raw materials into the septic tank, impurities in the raw materials are prone to accumulate and adhere to the reinforcing plate during the process of the raw materials falling into the septic tank, causing the ventilation holes to become blocked, which affects the decompression of the gas inside the septic tank. In order to address the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content
