Description

Technical Field

[0001] The utility model relates to the field of septic tanks, in particular to a septic tank exhaust device. Background Art

[0002] Septic tanks are equipment that treats feces and filters and precipitates them. The principle is that the solidified matter decomposes at the bottom of the tank, and the hydrated matter on the upper layer flows into the pipe, preventing the pipe from being blocked and giving the solidified matter enough time to hydrolyze. Septic tanks refer to small treatment structures that separate and precipitate domestic sewage and perform anaerobic digestion of sludge. In the process of digesting and degrading organic matter in septic tanks, a large amount of gas will be produced due to the activity of microorganisms, among which methane and ammonia are flammable gases. When their concentration reaches a certain amount, they will explode when exposed to open flames. Therefore, a septic tank exhaust device is needed to facilitate the treatment of these gases.

[0003] In a Chinese patent, an automatic exhaust device for a septic tank is disclosed, and its patent number is CN213012513U. In the automatic exhaust device for a septic tank in the patent, a septic tank and an exhaust device are included. A sealing cover is provided on the septic tank, and an air supply pipe is installed on the sealing cover. A connecting pipe is provided in the middle of the air supply pipe, and connecting sleeves are provided at both ends of the connecting pipe to connect with the air supply pipe. A vertical plate is provided in the connecting pipe, and an upper circular plate is provided on one side of the upper end of the vertical plate to connect with the inner wall of the connecting pipe, and a lower circular plate is provided on the other side of the lower end of the connecting pipe. It is connected to the inner wall of the connecting pipe, and a placement hole is arranged on the lower circular plate. The exhaust device includes an air guide pipe and a sphere. The air guide pipe is a conical bucket structure. The lower end of the air guide pipe extends to the placement hole and is sealed and connected to the lower circular plate. The sphere is movably arranged in the air guide pipe, and a movable chain is arranged on the sphere to be connected to the inner wall of the air guide pipe. An automatic exhaust device for a septic tank can realize automatic discharge of biogas from a septic tank through the septic tank, connecting pipe and exhaust device, and isolate it from the outside air without manual operation, thereby effectively improving the fermentation efficiency of the septic tank.

[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0039] like Figures 1 to 5 As shown, a septic tank exhaust device includes a septic tank 1, a connecting pipe 2 is arranged above the septic tank 1, and a storage box 3 is connected thereto. A pressure sensor 4 is arranged on the surface of the storage box 3 to monitor the pressure difference between the inside and the outside in real time. A breathable plate 5 fixed on the inner side of the storage box 3 allows biogas to pass through it and enter the next component. A support plate 601 is arranged on the elastic valve 6 located above the breathable plate 5. A moving rod 602 sliding on the surface of the support plate 601 allows a sealing plug 1 603 to discharge biogas under the elastic force control of a spring 2 604. The regulating assembly 7 on one side of the valve 6 is provided with a small motor 701, and the position of the regulating plate 703 is controlled by the screw 702 at the output end of the small motor 701 with the assistance of the limiting rod 705, so that the sealing plug 704 on the bottom surface of the regulating plate 703 can adjust the flow rate of biogas, and the purification box 8 fixed above the storage box 3 discharges the purified biogas through the exhaust port 801 at the upper end. An activated carbon adsorption plate 9 limited by a limiting plate 18 is provided on the inner side of the purification box 8, so that the activated carbon adsorption plate 9 can be disassembled and assembled at will through the buckle assembly 10.

[0040] The buckle assembly 10 is provided with a fixed plate 11 fixed on the surface of the storage box 3, so that the adjustment member 13 can slide in the straight groove 12 located on one side of the fixed plate 11, thereby driving the movable plate 14 to slide on the surface of the sliding rod 15 fixed and inside the straight groove 12, and under the control of the elastic force of the spring 16, the insertion rod 17 can be inserted into the limit plate 18 and the inner side of the activated carbon adsorption plate 9.

[0041] Through the above technical solution, under the elastic force of spring 16, the insertion rod 17 on the surface of the movable plate 14 is pushed to fix the activated carbon adsorption plate 9, so that it can be drawn out from the inside of the purification box 8 at any time and replaced.

[0042] The upper and lower ends of the connecting pipe 2 are provided with rotating parts 201 rotating on the surface thereof, so that the rotating part 201 is connected to the septic tank 1 and the storage box 3 through a threaded ring 202 connected with an inner thread.

[0043] Through the above technical solution, with the cooperation of the rotating part 201 and the threaded ring 202, the connecting pipe 2 can be removed from the surface of the septic tank 1 and the storage box 3 at any time, which is convenient for subsequent maintenance, and the threaded connection between the two can also make the sealing effect of the connection better.

[0044] A plurality of through holes 501 with a conical structure are arranged on the surface of the air permeable plate 5 .

When the biogas concentration is high, it is sensed by the pressure sensor 4, thereby sending a signal to the small motor 701, starting the small motor 701, and driving the adjustment plate 703 to rise through the screw 702, so that the sealing plug 704 is separated from the through hole 501, thereby expanding the air permeability of the air permeable plate 5. The biogas passing through the air permeable plate 5 will enter the inner side of the purification box 8, and after being adsorbed by the activated carbon adsorption plate 9, it will be discharged from the exhaust port 801. After a period of use, the activated carbon adsorption plate 9 can be pulled out for replacement through the cooperation of the snap assembly 10.
