Description

Technical Field

[0001] The utility model relates to the technical field of septic tanks, in particular to an explosion-proof septic tank for building facilities. Background Art

[0002] A septic tank system refers to a small treatment system that divides and precipitates domestic sewage and anaerobically digests sludge. It is a device for treating feces and filtering and precipitating them. The principle is that the solidified substances decompose at the bottom of the tank, and the upper hydrated substances enter the pipeline and flow away, preventing pipeline blockage and giving sufficient time for the solidified substances to hydrolyze.

[0003] For example, Chinese Patent No. CN208562098U proposes an explosion-proof device for a septic tank. This patent adds structures such as a fixed pipe, a piston, a first sealing plate, a telescopic rod, an L-shaped rod, a steel cable, a fixed pulley, a second sealing plate, a slider, a first magnet, a second magnet, a third sealing plate, and a resisting rod. As the methane gas in the septic tank increases, the air pressure in the septic tank will increase, causing the piston to move upward under the pushing force of the pressure. The movement of the piston will pull the steel cable, and the movement of the steel cable will pull the second sealing plate. The movement of the piston will cause the resisting rod to pass through the resisting hole and push the first sealing plate to move. When the pulling force of the steel cable is greater than the suction force between the first magnet and the second magnet, the continued movement of the piston will cause the second sealing plate to move away from the third sealing plate, thus connecting the fixed pipe to the outside. As the piston continues to move, the resisting rod will push the first sealing plate out of the sealing groove, allowing the gas in the septic tank to flow out, thereby reducing the air pressure in the septic tank and preventing explosion. However, in this solution, since the gas inside the septic tank may have an odor, directly discharging the gas without treating the odor of the gas inside the septic tank into the air may cause the odor gas to affect the lives of others, affect the explosion-proof effect of the septic tank, and is not conducive to the staff using the septic tank.

[0023] Embodiment 1

[0024] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7, an explosion-proof septic tank for building facilities, including a septic tank body 1. A fixing hole 2 is opened on the top surface of the septic tank body 1. A support box 3 is fixedly sleeved inside the fixing hole 2. An explosion-proof component is arranged on the bottom surface of the support box 3 to prevent the septic tank body 1 from exploding. The explosion-proof component includes a mounting hole 16 opened on the bottom surface of the support box 3. An air pump 17 is fixedly sleeved on the inner circular wall surface of the mounting hole 16. A support hole 9 is opened on one side of the support box 3. A support frame 10 is movably sleeved inside the support hole 9. An activated carbon filter screen 15 is fixedly sleeved inside the support frame 10. A limiting groove 14 is opened on one side inside the support box 3. The support frame 10 is movably sleeved with the limiting groove 14. Exhaust holes 11 are opened on both sides of the support box 3. An exhaust pipe 12 is fixedly sleeved on the inner circular wall surface of the exhaust hole 11. Two movable plates 20 are arranged on one side of the support frame 10. A spring 26 is fixedly installed between the two movable plates 20. A movable hole 23 is opened on one side of the movable plate 20. A positioning column 24 is movably sleeved on the inner circular wall surface of the movable hole 23. One end of the positioning column 24 is fixedly connected to one side of the support frame 10. A limiting block 22 is fixedly installed on one side of the movable plate 20.
