Description

Technical Field

[0001] This invention relates to the field of livestock and poultry manure recycling, specifically to an integrated equipment and method for the resource utilization and treatment of livestock and poultry manure. Background Technology

[0002] If livestock and poultry manure is discharged directly without proper treatment, it will cause serious pollution to soil, water and air. Nutrients such as nitrogen and phosphorus in manure can easily cause eutrophication when they enter water bodies, and the resulting malodorous gases such as hydrogen sulfide and ammonia will affect the surrounding air quality. The spread of pathogens and parasite eggs will threaten public health and safety.

[0003] Existing livestock and poultry manure treatment equipment requires stirring and oxygen injection during use to meet the aerobic metabolism needs of microorganisms. However, existing equipment generally uses separate annular stirring flow within the same layer, resulting in uneven stirring of livestock and poultry manure inside the tank and poor aeration effect. Therefore, it is necessary to propose an integrated equipment and treatment method for the resource utilization of livestock and poultry manure. Summary of the Invention

[0004] To address the problems in the existing technology, this invention provides an integrated equipment and method for the resource utilization and treatment of livestock and poultry manure.

[0005] The technical solution adopted by this invention to solve its technical problem is: an integrated equipment for the resource utilization and treatment of livestock and poultry manure, including a tank, a drive assembly fixedly installed at the top of the tank, an inlet and outlet assembly fixedly installed on the tank, a rotating rod rotatably connected to the inside of the tank via a bearing, the upper end of the rotating rod extending out of the tank and connected to the drive assembly, a stirring rod fixedly installed at one end of the rotating rod inside the tank, an air inlet groove penetrating the rotating rod, an installation rod fixedly connected to the rotating rod, a connecting pipe fixedly connected to the rotating rod, a baffle plate fixedly installed on the installation rod and the connecting pipe, a rotating hole opened on the baffle plate, a support rod rotatably connected in the rotating hole, several baffles fixedly connected to the support rod, a conveying pipe fixedly connected to the connecting pipe, a spray nozzle fixedly installed on the conveying pipe, and a temperature sensor fixedly installed on the rotating rod.

[0006] Specifically, the drive assembly includes a motor, which is fixedly mounted on the upper surface of the tank. A first bevel gear is fixedly mounted on the output end of the motor via a coupling, and a second bevel gear is fixedly mounted on the end of the rotating rod located outside the tank. The first bevel gear meshes with the second bevel gear.

[0007] Specifically, the feeding and discharging assembly includes a feeding pipe, a discharging pipe, and an exhaust pipe. The feeding pipe is fixedly installed on the inner wall of the top of the tank, the discharging pipe is fixedly installed at the center of the lower end of the tank, and the exhaust pipe is fixedly installed on the inner wall of the top of the tank.

[0008] Specifically, the upper ends of the feed pipe and the exhaust pipe extend outside the tank and are arranged at an angle, while the lower end of the discharge pipe extends outside the tank and is fixedly equipped with a solenoid valve.

[0009] Specifically, the lower end of the tank's interior is funnel-shaped.

[0010] Specifically, the upper opening of the air inlet groove is arranged to pass through the upper end of the rotating rod, the air inlet groove is connected to the connecting pipe, and the connecting pipe is connected to the conveying pipe.

[0011] Specifically, the spray nozzle is inclined, and the top end of the delivery pipe connected to the spray nozzle is a pipe joint with integrated one-way function.

[0012] A method for the resource utilization and treatment of livestock and poultry manure includes the following steps: The first step is to collect livestock and poultry manure (such as pig manure, chicken manure, etc.), and then remove large impurities (such as straw, feathers, etc.) to avoid clogging the tank and to facilitate the internal equipment to process the livestock and poultry manure. The second step is to adjust the moisture content (usually controlled at 60%~70%) and carbon-nitrogen ratio (C / N ratio of about 20~30:1) of livestock and poultry manure by adding water to it or by extracting the liquid from the manure, so as to create a suitable environment for microbial activity. The third step involves injecting livestock and poultry manure into the tank through the feed pipe. The manure undergoes aerobic fermentation inside the tank, and the internal temperature is monitored by a temperature sensor. The fourth step involves driving the stirring rod to stir the livestock and poultry manure when the internal temperature is below the high temperature (50~70℃) and when it is necessary to stir and aerate the interior at regular intervals. At the same time, air is injected into the interior to cause the spray nozzles to spray oxygen. The oxygen will drive the baffle to rotate, and the baffle will cause the livestock and poultry manure to flow up and down. The livestock and poultry manure flowing up and down will be separated into large and small rotating circles by the baffle. At the same time, the oxygen sprayed by the spray nozzles will mix with the livestock and poultry manure flowing along the baffle. The fifth step involves maintaining an aerobic environment inside the tank, where aerobic microorganisms (such as Bacillus and Actinomycetes) multiply rapidly and decompose organic matter. High-temperature sterilization (killing pathogens and insect eggs) can be completed in 5-7 days, followed by 7-10 days of composting and stabilization, ultimately forming well-rotted organic fertilizer. The sixth step involves transporting the gas generated during fermentation to the waste gas treatment equipment through the exhaust pipe, where it is treated and then discharged. The fermented organic fertilizer in the tank can be discharged through the discharge pipe by opening the solenoid valve, and then undergoes further screening for impurities, testing for indicators, aging, and processing for utilization.

[0013] The beneficial effects of this invention are as follows: The integrated equipment and method for the resource utilization and treatment of livestock and poultry manure described in this invention, during use, involves starting the drive device to drive the rotating rod, which in turn drives the stirring rod to stir the livestock and poultry manure. Simultaneously, air is injected into the air inlet trough, which delivers oxygen to the spray nozzle for spraying. The sprayed oxygen impacts the baffle plate, causing it to rotate. The baffle plate drives the livestock and poultry manure to flow up and down, and oxygen mixes with the flowing manure. Under the control of the baffle plate, a small portion of the manure flows through the rotating holes in a small circular motion, while the majority of the manure flows upward or downward on both sides of the baffle plate, resulting in a larger circular motion. This improves the flowability of the manure and the mixing effect with the injected oxygen, thus facilitating aerobic fermentation of the manure. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-6 As shown, the present invention provides an integrated equipment for the resource utilization and treatment of livestock and poultry manure, comprising a tank 1, a drive assembly fixedly installed at the top of the tank 1, an inlet and outlet assembly fixedly installed on the tank 1, a rotating rod 2 rotatably connected inside the tank 1 via a bearing, the upper end of the rotating rod 2 extending outside the tank 1 and connected to the drive assembly, a stirring rod 3 fixedly installed at one end of the rotating rod 2 inside the tank 1, an air inlet groove 4 penetrating through the rotating rod 2, an installation rod 5 fixedly connected to the rotating rod 2, a connecting pipe 6 fixedly connected to the rotating rod 2, a baffle 7 fixedly installed on the installation rod 5 and the connecting pipe 6, a rotating hole 8 opened on the baffle 7, a support rod 9 rotatably connected inside the rotating hole 8, several baffles 10 fixedly connected to the support rod 9, a conveying pipe 11 fixedly connected to the connecting pipe 6, a spray nozzle 12 fixedly installed on the conveying pipe 11, and a temperature sensor 20 fixedly installed on the rotating rod 2. The drive assembly includes a motor 13, which is fixedly mounted on the upper surface of the tank 1. A first bevel gear 14 is fixedly mounted on the output end of the motor 13 via a coupling. A second bevel gear 15 is fixedly mounted on the end of the rotating rod 2 located outside the tank 1. The first bevel gear 14 and the second bevel gear 15 mesh with each other. The feeding and discharging assembly includes a feed pipe 16, a discharge pipe 17, and an exhaust pipe 18. The feed pipe 16 is fixedly installed on the inner wall of the top of the tank 1, the discharge pipe 17 is fixedly installed at the center of the lower end of the tank 1, and the exhaust pipe 18 is fixedly installed on the inner wall of the top of the tank 1. The gas generated during fermentation is transported to the waste gas treatment equipment through the exhaust pipe 18 and then discharged after treatment. The upper ends of the feed pipe 16 and the exhaust pipe 18 extend outside the tank 1 and are arranged at an angle. The feed pipe 16 is connected to an external conveying device, and feed is fed into the tank 1 through the conveying device and the feed pipe 16. The lower end of the discharge pipe 17 extends outside the tank 1 and is fixedly installed with a solenoid valve 19. The lower end of the tank 1 is funnel-shaped. The fermented organic fertilizer in the tank 1 can be discharged through the discharge pipe 17 by opening the solenoid valve 19. The upper opening of the air inlet 4 is set through the upper end of the rotating rod 2. The air inlet 4 is connected to the connecting pipe 6, which is connected to the conveying pipe 11. The air inlet 4 is connected to an external oxygen injection device, and oxygen is injected into the air inlet 4 through the oxygen injection device. The spray nozzle 12 is set at an angle, and the top end of the connection between the conveying pipe 11 and the spray nozzle 12 is an integrated one-way pipe joint to prevent liquid in the livestock and poultry manure from seeping into the pipe through the spray nozzle 12 when it is not in use.

[0019] A method for the resource utilization and treatment of livestock and poultry manure includes the following steps: The first step is to collect livestock and poultry manure (such as pig manure, chicken manure, etc.), and then remove large impurities (such as straw, feathers, etc.) to avoid clogging the feed pipe 16 and to avoid tangling the mixing rod 3 and the baffle plate 10, thereby facilitating the feeding and aeration of livestock and poultry manure. The second step is to adjust the moisture content (usually controlled at 60%~70%) and carbon-nitrogen ratio (C / N ratio of about 20~30:1) of livestock and poultry manure by adding water to it or by extracting the liquid from the manure, so as to create a suitable environment for microbial activity. The third step is to inject livestock and poultry manure into the tank 1 through the feed pipe 16. The livestock and poultry manure undergoes aerobic fermentation in the tank 1, and the internal temperature is monitored by the temperature sensor 20. Fourthly, when the internal temperature is below the high temperature (50~70℃) or when internal aeration is required periodically, motor 13 is started. Motor 13 drives the first bevel gear 14 to rotate, and the first bevel gear 14, through meshing with the second bevel gear 15, drives the rotating rod 2 to rotate. The rotating rod 2 drives the stirring rod 3 to stir the livestock and poultry manure, causing the manure to flow in a circular parallel flow. At the same time, oxygen is injected into the air inlet trough 4 through the air injection device. The oxygen is injected into the connecting pipe 6 through the air inlet trough 4, and then enters the conveying pipe 11 through the connecting pipe 6. The conveying pipe 11 delivers the oxygen to the spray nozzle 1. Oxygen is sprayed through nozzle 12 at two locations, which drives the baffle 10 to rotate. When the baffle 10 rotates, it causes the flowing livestock and poultry manure to flow up and down. A small portion of the livestock and poultry manure flows with the space between adjacent baffles 10 and passes through the rotating hole 8 to exchange between the upper and lower layers in a small circular motion. Most of the flowing livestock and poultry manure is blocked by the baffle 7 and flows up and down on both sides of the baffle 7, so that most of the livestock and poultry manure will exchange between the upper and lower layers in a large circular motion. At the same time, the oxygen sprayed by nozzle 12 is dispersed by baffle 10 and mixed in with the flowing livestock and poultry manure. The fifth step involves maintaining an aerobic environment inside tank 1, where aerobic microorganisms (such as Bacillus, Actinomycetes, etc.) multiply rapidly and decompose organic matter. High-temperature sterilization (killing pathogens and insect eggs) can be completed in 5-7 days, followed by 7-10 days of composting and stabilization, ultimately forming well-rotted organic fertilizer. The sixth step involves sending the gas generated during fermentation to the waste gas treatment equipment through the exhaust pipe 18, and then discharging it after treatment. The organic fertilizer that has been fermented in the tank 1 can be discharged through the discharge pipe 17 by opening the solenoid valve 19. Then, it will be screened for impurities, tested for indicators, aged, and processed for utilization.
