Description

Technical Field

[0001] The present invention relates to the technical field of septic tanks, and in particular to a safety deodorization system for septic tank treatment. Background Art

[0002] A septic tank is a device for treating feces and filtering and precipitating them. A septic tank refers to a small treatment structure that divides domestic sewage into compartments for precipitation and anaerobically digests sludge. During the operation of a septic tank, gases are generated, and these gases need to be discharged. The discharged gases have a foul smell and are directly discharged into the external environment. At the same time, these gases often contain biogas. Therefore, a corresponding safety deodorization system is required to treat the gases generated by the septic tank.

[0003] After retrieval, a patent with the Chinese patent application number CN201611105917.3 discloses a safety deodorization device for septic tank malodorous gases, including an ozone generation device, an ozone generation device cooling system, a gas pipeline mixing device, etc.; the ozone generation device and the ozone generation device cooling system are connected to a fixing device. However, in the above technical solution, since the gases in the septic tank are continuously pumped into the gas treatment system by an induced draft fan, and the gases generated by the reaction in the septic tank are relatively slow, the continuously operating induced draft fan is likely to pump the air existing in the septic tank into the gas treatment system, resulting in a relatively low air pressure inside the septic tank, thereby affecting the normal reaction inside the septic tank. At the same time, the continuously operating induced draft fan is prone to overheating, and once the temperature inside the induced draft fan is too high, it is easy to cause an explosion of the biogas in the septic tank. Therefore, there is also a problem that the long-term operation of the induced draft fan for pumping out the gases from the septic tank is likely to affect the normal reaction of the objects inside the septic tank and reduce the safety of the septic tank during use.

[0009] More preferably, the gas storage mechanism includes a third exhaust pipe, a gas storage tank and an exhaust valve. The third exhaust pipe is arranged on the outer wall of one side of the third exhaust pipe, the gas storage tank is arranged on the outer wall of one side of the third exhaust pipe, and the exhaust valve is arranged on the outer wall of the top of the gas storage tank.

[0010] As a preferred embodiment of the present invention, a group of guiding blocks are fixed on the outer wall of one side of the movable plate, a guiding through groove is formed on the outer wall of the top of the temporary storage tank, a pointer is arranged on the outer wall of the top of the guiding block, and the pointer is slidably connected to the inner wall of the guiding through groove.

[0011] As a further preferred embodiment of the present invention, a limiting groove is formed on the inner wall of the bottom of the temporary storage tank, the guiding block is slidably connected to the inner wall of the limiting groove, a push rod is fixed on the outer wall of one side of the movable plate, a sealing ring is arranged on the outer wall of one side of the temporary storage tank, and the push rod is slidably connected to the inner wall of the sealing ring.

[0012] As a further scheme of the present invention, elastic sealing bands are respectively arranged on the outer walls of both sides of the pointer, one end of the elastic sealing band is fixed on the inner wall of the guiding through groove, and a scale ruler is arranged on the outer wall of the top of the temporary storage tank.

[0014] On the basis of the foregoing scheme preferably, a cooling box is arranged on the outer wall of the third exhaust pipe, a circulation pipe is arranged on the outer wall of the top of the cooling box, a water storage frame is arranged on the outer wall of the bottom of the cooling box, a circulation pump is arranged on the outer wall of the bottom of the water storage frame, one end of the circulation pipe is arranged on the outer wall of the bottom of the circulation pump, one side of the third exhaust pipe is arranged on the outer wall of one side of the cooling box, the circulation pipe penetrates through the outer wall of the top of the cooling box, a spraying plate is arranged on the outer wall of one side of the circulation pipe, a temperature sensor is arranged on the inner wall of the cooling box, and the temperature sensor and the circulation pump are respectively electrically connected to the control panel.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention can regularly send the gas generated during the operation inside the septic tank body into the filtering mechanism and the gas storage mechanism for purification treatment without keeping the air extraction pump running all the time. At the same time, it can keep the air pressure inside the septic tank body at a normal value all the time, enabling the septic tank body to stably treat wastes such as feces. Meanwhile, the intermittently and regularly working air extraction pump can also timely dissipate the heat generated during operation, avoiding deflagration of combustible gas when passing through the air extraction pump, and improving the safety during the operation of the septic tank body.

[0017] 2. The elastic airbag will push the movable plate forward according to its own expansion size, so that the staff can judge the amount of gas stored inside the temporary storage box through the pointer protruding from the temporary storage box. When the position of the pointer is close to the side of the sealing plate, it indicates that only a small amount of gas enters the temporary storage box through the air guide cover. Therefore, the air extraction pump still needs to run for a long time. At this time, the staff can open the filter box to clean and replace the activated carbon filter plate inside the filter box, avoiding gas leakage inside the temporary storage box while enabling the staff to conveniently and quickly replace and maintain the activated carbon filter plate.

[0018] 3. The limit groove can cooperate with the guiding through groove to guide and limit the movable plate during forward and backward movement. At the same time, the staff presses the push rod to judge whether the elastic airbag leaks air, and can manually reset the movable plate by pushing the push rod, facilitating the staff to adjust the positions of the elastic airbag and the movable plate.

[0019] 4. The combustible gas sensor can detect the gas entering the filter box. When there is combustible gas in the gas entering the filter box through the air extraction pump, the electric control reversing valve will connect the third exhaust pipe with the gas storage tank, allowing these combustible gases to be filled into the gas storage tank for temporary storage, facilitating the subsequent utilization and treatment of these combustible gases by the staff. When the gas filled into the filter box by the air extraction pump next time does not contain combustible gas, the control panel will control the electric control reversing valve to conduct the third exhaust pipe with the second exhaust pipe, so that the deodorized and filtered gas is directly discharged through the second exhaust pipe.

[0020] 5. The temperature sensor can detect the temperature of the gas entering the cooling box. When the gas temperature exceeds the set value, the control panel will control the circulation pump to run, filling the water inside the water storage frame into the spraying plate through the circulation pipe, and turning this water into water mist and spraying it outwards through the spraying plate, thereby cooling the gas passing through the inside of the cooling box, avoiding deflagration of combustible gas due to too high temperature, and further improving the safety during the operation of the safety deodorization system.

Detailed implementation manners

[0028] The technical solutions of this patent will be further described in detail below in combination with the specific implementation manners.

[0029] The embodiments of this patent will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and cannot be understood as a limitation of this patent.

[0030] Embodiment 1:

[0031] A safety deodorization system for septic tank treatment, as Figure 1-6As shown in the figure, it includes a septic tank body 1. A second air outlet pipe 12 is provided on the outer wall of the top of the septic tank body 1. A gas guide hood 3 is provided on the outer wall of one side of the second air outlet pipe 12. A temporary storage box 4 is provided on the outer wall of one side of the gas guide hood 3. A first air outlet pipe 10 is provided on the outer wall of the top of the temporary storage box 4. An air extraction pump 9 is provided on the outer wall of the first air outlet pipe 10. A filtering mechanism and a gas storage mechanism are provided on the outer wall of one side of the air extraction pump 9. A sealing plate 33 is fixed on the inner wall of the temporary storage box 4. A circular through hole is opened on the outer wall of one side of the sealing plate 33. An elastic airbag 27 is fixed on the inner wall of the circular through hole. A movable plate 31 is fixed on the outer wall of one side of the elastic airbag 27. A stop block 25 is fixed on the outer wall of one side of the sealing plate 33. A first touch button 26 is provided on the outer wall of one side of the stop block 25. A second touch button 30 is provided on the inner wall of one side of the temporary storage box 4. Water outlet 2 and liquid inlet pipe 13 are respectively provided on the outer walls of both sides of the septic tank body 1. A maintenance opening 11 is provided on the outer wall of the top of the septic tank body 1. A control panel 16 is fixed on the outer wall of one side of the temporary storage box 4. The air extraction pump 9, the first touch button 26 and the second touch button 30 are respectively electrically connected to the control panel 16.

[0032] As the gas generated during the operation inside the septic tank body 1 continuously increases, these gases will enter the gas guide hood 3 through the second air outlet pipe 12 and enter the inside of the temporary storage box 4 under the guidance of the gas guide hood 3. The gas entering the inside of the temporary storage box 4 will enter the elastic airbag 27 through the circular through hole on one side of the sealing plate 33, causing the elastic airbag 27 to gradually expand as these gases continuously pour in. When expanding, the elastic airbag 27 will push the movable plate 31 on one side forward. As the gas inside the septic tank body 1 and the temporary storage box 4 continuously increases, the elastic airbag 27 will also continuously expand outwards. The movable plate 31 will be pushed by the elastic airbag 27 and abut against one side of the second touch button 30. After being collided, the second touch button 30 will control the air extraction pump 9 to operate. When the air extraction pump 9 operates, it will quickly extract the gas inside the temporary storage box 4 and the septic tank body 1 through the first air outlet pipe 10. While quickly restoring the normal pressure inside the temporary storage box 4, it will cause the elastic airbag 27 to drive the movable plate 31 on one side to reset. When the elastic airbag 27 contracts to the smallest size under the suction of the air extraction pump 9, the outer wall of one side of the movable plate 31 will abut against the first touch button 26. At this time, the control panel 16 will control the air extraction pump 9 to close, thus ending this air extraction operation.

[0033] Therefore, without having to keep the air extraction pump 9 running all the time, the gas generated during the operation inside the septic tank body 1 can be regularly sent to the filtering mechanism and the gas storage mechanism for purification treatment. At the same time, the air pressure inside the septic tank body 1 can always be maintained at a normal value, enabling the septic tank body 1 to stably treat wastes such as feces. Meanwhile, the intermittently and regularly operating air extraction pump 9 can also timely dissipate the heat generated during operation, avoiding deflagration when combustible gas passes through the air extraction pump 9, and improving the safety of the septic tank body 1 during operation.

[0034] Such asFigure 1-6 As shown in the figure, the filtering mechanism includes a first exhaust pipe 17, a filtering box 15, a third exhaust pipe 24 and an activated carbon filter plate 38. The first exhaust pipe 17 is arranged on the outer wall of one side of the air extraction pump 9, the filtering box 15 is arranged on the outer wall of the bottom of the first exhaust pipe 17, the activated carbon filter plate 38 is arranged on the inner wall of the filtering box 15, and the third exhaust pipe 24 is arranged on the outer wall of the bottom of the filtering box 15; The gas extracted by the air extraction pump 9 will enter the filtering box 15 through the first exhaust pipe 17. The activated carbon filter plate 38 on the inner wall of the filtering box 15 can effectively filter out the odor in these gases, so as to achieve the effect of filtering and deodorizing. The gas after filtering and deodorizing is sent into the gas storage mechanism through the third exhaust pipe 24.

[0035] As Figure 1-5 shown in the figure, the gas storage mechanism includes a third exhaust pipe 20, a gas storage tank 7 and an exhaust valve 8. The third exhaust pipe 20 is arranged on the outer wall of one side of the third exhaust pipe 24, the gas storage tank 7 is arranged on the outer wall of one side of the third exhaust pipe 20, and the exhaust valve 8 is arranged on the outer wall of the top of the gas storage tank 7; The gas after filtering and deodorizing enters the gas storage tank 7 under the guidance of the third exhaust pipe 20 for temporary storage, which is convenient for the staff to recycle these gases.

[0036] As Figure 1-5 shown in the figure, a group of guide blocks 28 are fixed on the outer wall of one side of the movable plate 31. A guide through groove 29 is opened on the outer wall of the top of the temporary storage box 4. A pointer 36 is arranged on the outer wall of the top of the guide block 28. The pointer 36 is slidably connected to the inner wall of the guide through groove 29; The elastic air bag 27 will push the movable plate 31 forward according to its own expansion size, so that the staff can judge the amount of gas stored in the temporary storage box 4 through the pointer 36 protruding out of the temporary storage box 4. When the position of the pointer 36 is close to one side of the sealing plate 33, it indicates that only a small amount of gas enters the temporary storage box 4 through the air guide cover 3. Therefore, the air extraction pump 9 still needs to run for a long time. At this time, the staff can open the filtering box 15 to clean and replace the activated carbon filter plate 38 inside the filtering box 15, while avoiding gas leakage inside the temporary storage box 4, and enabling the staff to conveniently and quickly replace and maintain the activated carbon filter plate 38.

[0037] As Figure 4 shown in the figure, a limiting groove 32 is opened on the inner wall of the bottom of the temporary storage box 4. The guide block 28 is slidably connected to the inner wall of the limiting groove 32. A push rod 6 is fixed on the outer wall of one side of the movable plate 31. A sealing ring 5 is arranged on the outer wall of one side of the temporary storage box 4. The push rod 6 is slidably connected to the inner wall of the sealing ring 5; The limiting groove 32 can cooperate with the guide through groove 29 to guide and limit the movable plate 31 during forward and backward movement. At the same time, the staff presses the push rod 6 to judge whether the elastic air bag 27 leaks air, and can manually reset the movable plate 31 by pushing the push rod 6, which is convenient for the staff to adjust the positions of the elastic air bag 27 and the movable plate 31.

[0038] As Figure 5 shown, elastic sealing bands 35 are respectively arranged on the outer walls on both sides of the pointer 36. One end of the elastic sealing band 35 is fixed on the inner wall of the guiding through groove 29, and a scale ruler 34 is arranged on the outer wall of the top of the temporary storage box 4. The staff can accurately judge the expansion degree of the elastic airbag 27 through the scale ruler 34. The elastic sealing band 35 can block and seal the guiding through groove 29 to prevent external dust from entering the interior of the temporary storage box 4 through the guiding through groove 29.

[0039] As Figure 1-6 shown, a combustible gas sensor 37 is fixed on the inner wall of the filter box 15. An electronically controlled reversing valve 21 is arranged on the outer wall of the third exhaust pipe 20, and a second exhaust pipe 19 is arranged on the outer wall of the top of the electronically controlled reversing valve 21. The combustible gas sensor 37 and the electronically controlled reversing valve 21 are respectively electrically connected to the control panel 16. The combustible gas sensor 37 can detect the gas entering the interior of the filter box 15. When there is combustible gas in the gas filled into the filter box 15 by the air extraction pump 9, the electronically controlled reversing valve 21 will connect the third exhaust pipe 20 with the gas storage tank 7, so that these combustible gases are filled into the interior of the gas storage tank 7 for temporary storage, which is convenient for the staff to utilize and process these combustible gases later. When the gas filled into the filter box 15 by the air extraction pump 9 next time does not contain combustible gas, the control panel 16 will control the electronically controlled reversing valve 21 to conduct the third exhaust pipe 20 and the second exhaust pipe 19, so that the deodorized and filtered gas is directly discharged through the second exhaust pipe 19.

[0040] When this embodiment is in use, sewage flows into the septic tank body 1 through the liquid inlet pipe 13, and the water treated by the septic tank body 1 is discharged outward through the water outlet 2. The staff can perform maintenance on the interior of the septic tank body 1 through the maintenance opening 11.

[0041] As the gas generated during the operation inside the septic tank body 1 continuously increases, these gases will enter the air guide hood 3 through the second air outlet pipe 12, and enter the inside of the temporary storage tank 4 under the guidance of the air guide hood 3. The gases entering the inside of the temporary storage tank 4 will enter the elastic airbag 27 through the circular through-hole on one side of the sealing plate 33, causing the elastic airbag 27 to gradually expand as these gases continuously pour in. When expanding, the elastic airbag 27 will push the movable plate 31 on one side forward. As the gases inside the septic tank body 1 and the temporary storage tank 4 continuously increase, the elastic airbag 27 will also continuously expand outwards. The movable plate 31 will be pushed by the elastic airbag 27 and press against one side of the second touch button 30. After being collided, the second touch button 30 will control the operation of the air extraction pump 9. When the air extraction pump 9 operates, it will quickly extract the gases inside the temporary storage tank 4 and the septic tank body 1 through the first air outlet pipe 10, causing the elastic airbag 27 to drive the movable plate 31 on one side to reset. When the elastic airbag 27 shrinks to the smallest size under the suction of the air extraction pump 9, the outer wall of one side of the movable plate 31 will press against the first touch button 26. At this time, the control panel 16 will control the air extraction pump 9 to shut down, thus ending this air extraction operation, keeping the air pressure inside the septic tank body 1 at a normal value all the time, and enabling the septic tank body 1 to stably treat wastes such as feces.

[0042] The gases after being filtered and deodorized enter the inside of the gas storage tank 7 for temporary storage under the guidance of the third exhaust pipe 20, which is convenient for the staff to recycle these gases. The gases extracted by the air extraction pump 9 will enter the filter box 15 through the first exhaust pipe 17. The activated carbon filter plate 38 on the inner wall of the filter box 15 can effectively filter out the odor in these gases, thus achieving the effect of filtering and deodorizing. The gases after being filtered and deodorized are sent into the gas storage mechanism through the third air outlet pipe 24.

The temperature sensor 40 and the circulating pump 22 are respectively electrically connected to the control panel 16. The temperature sensor 40 can detect the temperature of the gas entering the inside of the cooling box 14. When the gas temperature exceeds the set value, the control panel 16 will control the circulating pump 22 to operate, fill the water inside the water storage frame 23 into the spraying plate 39 through the circulating pipe 18, and turn this water into water mist through the spraying plate 39 and sprinkle it outwards, so as to cool the gas passing through the inside of the cooling box 14, avoid the deflagration of combustible gas due to too high temperature, and further improve the safety during the operation of the safety deodorization system.

[0045] When this embodiment is in use, the temperature sensor 40 can detect the temperature of the gas entering the inside of the cooling box 14.
