Agricultural organic waste primarily includes crop straw and vines, livestock and poultry manure, and aquatic waste. Organic solid waste can be degraded using microbial decomposition equipment, achieving harmless treatment.

[0003] Existing multifunctional decomposition devices for organic solid waste usually include a tank body, a feed pipe, and an exhaust pipe. The tank body is usually a brick-concrete structure used to load organic solid waste and anaerobic bacteria. Anaerobic bacteria ferment and degrade the organic solid waste to form biogas and waste liquid. The biogas is discharged through the exhaust pipe for combustion, and the waste liquid can be used for fertilizing and irrigating farmland.

[0004] When the existing multifunctional organic solid waste decomposition device is in use, since the internal space of the tank is usually of fixed size, the biogas pressure inside the tank will fluctuate during biogas combustion, thereby affecting the stability of biogas discharge and combustion.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] See also Figure 1-4The embodiment provided by the present invention is a multifunctional decomposition device for organic solid waste, comprising a tank body 1 and an end cover 3. A groove 4 is provided in the middle of the tank body 1 for the end cover 3 to slide. The end cover 3 is made of aluminum alloy and is funnel-shaped. The outer size of the bottom of the end cover 3 is adapted to the inner size of the groove 4, thereby improving the sealing performance of the interior of the tank body 1. Oil can be poured onto the edge of the end cover 3 for sealing and lubrication. A feed pipe 2 is plugged into the side wall of the tank body 1, and a drain pipe 8 is plugged into the inner wall of the tank body 1 away from the feed pipe 2. The feed pipe 2 and the drainage pipe 8 are connected to the groove 4 in sequence. The top of the feed pipe 2 is connected to the toilet and the livestock plant through a pipe to transport feces to the inside of the tank body 1. The other end of the drainage pipe 8 is plugged with a water pump 9, which improves the convenience of waste liquid discharge. The bottom end of the drainage pipe 8 is plugged with a filter 13. The filter 13 is made of aluminum alloy and is cylindrical. The outer surface of the filter 13 is evenly spaced with a number of holes and slots for filtering impurities in the waste liquid. Starting the water pump 9 can extract the waste liquid inside the tank body 1 for irrigation. , which improves the stability of waste liquid discharge. The top of the end cover 3 is plugged with a mounting seat 5, and an exhaust pipe 10 is plugged into the side wall of the mounting seat 5. An air pump 7 is fixed to the side wall of the end cover 3 near the mounting seat 5 by bolts. The air pump 7 is connected to the exhaust pipe 10 through a pipeline. The exhaust port at the top of the air pump 7 is connected to the stove through a hose. Starting 7 can deliver biogas to the stove for combustion. A limiting hoop 12 is fixed on the inner side wall of the groove 4 near the bottom of the end cover 3 to prevent the end cover 3 from falling. The inner side wall of the groove 4 near the top of the end cover 3 A limiting hoop 11 is fixedly provided on the side wall. The tank body 1, limiting hoop 11 and limiting hoop 2 12 are all rotating mixing structures. The limiting hoop 11 can prevent the end cover 3 from sliding out of the groove 4. The operator starts the air pump 7 to discharge the biogas inside the tank body 1 through the exhaust pipe 10. When the biogas concentration inside the tank body 1 decreases, the end cover 3 moves vertically downward, so that the biogas pressure inside the tank body 1 reaches a dynamic balance, thereby ensuring that the biogas is stably discharged from the exhaust pipe 10 for combustion, thereby improving the stability of biogas combustion and utilization.

[0022] A sealing cover 15 is rotatably connected to the side wall of the end cover 3 away from the air pump 7, and a feeding port 14 is opened on the side wall of the end cover 3 close to the sealing cover 15. The feeding port 14 runs through the side wall of the tank body 1 to facilitate the addition of straw vines.

[0023] A climbing tube 6 is inserted into the top of the mounting seat 5 , and the climbing tube 6 is connected with the mounting seat 5 and the end cover 3 in sequence, thereby improving the convenience of biogas discharge.

[0024] Two protrusions 17 are symmetrically fixed on the inner side wall of the mounting base 5 near the top of the exhaust pipe 10. Two baffles 16 are rotatably connected to the inner side wall of the mounting base 5 near the top of the protrusion 17 through a torsion spring. The two baffles 16 are symmetrically distributed, and the external dimensions of the baffles 16 are adapted to the internal dimensions of the mounting base 5. When the biogas pressure inside the tank body 1 is greater than the dead weight of the baffle 16 and the torque of the torsion spring, the baffle 16 is made of cast iron and has a large dead weight. The torsion spring is a prior art and will not be described here. As a result, the baffle 16 is rotated upward, connecting the climbing tube 6 and the mounting base 5, which is convenient for reducing the internal air pressure of the tank body 1, thereby improving the safety of the decomposition device. When the internal pressure of the tank body 1 is reduced, the baffle 16 is supported on the top of the protrusion 17, thereby achieving closure of the mounting base 5.

[0025] Working principle: When using this multifunctional decomposition device for organic solid waste, the operator first connects an external power supply. The top end of the feed pipe 2 is connected to the toilet and livestock plant through a pipe to transport feces to the interior of the tank body 1. The end cover 3 is made of aluminum alloy and is funnel-shaped. The external dimensions of the bottom end of the end cover 3 are adapted to the internal dimensions of the groove 4, which improves the sealing of the interior of the tank body 1, thereby facilitating the anaerobic bacteria circle to ferment and degrade organic solid waste in the tank body 1, thereby generating biogas and waste liquid. The operator starts the air pump 7 to discharge the biogas inside the tank body 1 through the exhaust pipe 10. When the biogas concentration inside the tank body 1 decreases, the end cover 3 moves vertically downward, so that the biogas pressure inside the tank body 1 reaches a dynamic balance, thereby ensuring that the biogas is stably discharged from the exhaust pipe 10 for combustion, thereby improving the stability of biogas combustion utilization.

[0026] Secondly, when the internal air pressure of the tank body 1 is too high, the biogas pressure acts on the bottom end of the baffle 16. When the internal biogas pressure of the tank body 1 is greater than the deadweight of the baffle 16 and the torque of the torsion spring, the baffle 16 is made of cast iron and has a large deadweight. The torsion spring is a prior art and will not be described in detail here. As a result, the baffle 16 rotates upward, connecting the climbing tube 6 and the mounting seat 5, which facilitates reducing the internal air pressure of the tank body 1, thereby improving the safety of the decomposition device. When the internal pressure of the tank body 1 is reduced, the baffle 16 is supported on the top of the protrusion 17, thereby achieving closure of the mounting seat 5.
