Description

Technical Field

[0001] This invention relates to the field of organic fertilizer fermentation equipment, and in particular to a pig manure organic fertilizer fermentation equipment and its usage method. Background Technology

[0002] With the booming development of pig farming, the large amount of livestock waste has put immense pressure on pigsties and their surrounding environment, making pig manure disposal a major challenge. Fresh pig manure cannot be directly applied to fields; besides causing pests and diseases, it can burn seedlings, and its strong odor easily pollutes the environment. In 2022, small-scale pig farming accounted for about 30% of pig farming in my country, still representing a significant proportion. These small-scale farmers are often not skilled in pig manure disposal and often compost it directly in open areas. Pig manure contains a large number of organic microbial colonies, which consume a large amount of oxygen in water bodies during the decomposition of organic matter, while also emitting a strong odor, affecting groundwater quality and air quality. Furthermore, the high content of foul-smelling water in pig manure easily attracts mosquitoes, posing certain safety and hygiene hazards.

[0003] Currently, one of the main ways to utilize manure resources is through the production of organic fertilizer. Using pig manure to produce organic fertilizer not only solves the environmental pollution problem caused by pig manure accumulation, but also provides necessary organic fertilizer for agricultural development.

[0004] The temperature during aerobic fermentation of organic fertilizer is the overall manifestation of the heat energy absorbed and released by various microorganisms during their growth and metabolism within the compost pile. Generally, composting can be divided into three stages based on pile temperature: the warming stage, the high-temperature stage, and the maturation stage. The warming stage refers to the initial stage of temperature rise in the compost pile. During this period, mesophilic microorganisms multiply rapidly by decomposing low molecular weight substances (such as amino acids, oligosaccharides, and monosaccharides), causing the pile temperature to rise rapidly. When the pile temperature reaches above 45℃, it enters the high-temperature stage. In this stage, mesophilic microorganisms are inhibited, while thermophilic microorganisms (mainly fungi and actinomycetes) begin to multiply rapidly and degrade various complex macromolecular organic matter (such as cellulose and proteins) in the pile. Furthermore, the high temperature can kill most parasite eggs and pathogens in the pile. Therefore, modern composting defines maturation as maintaining a fermentation temperature above 50℃ for more than 7 days or above 55℃ for more than 5 days. After the high-temperature stage, various organic substances in the pile are almost completely consumed, causing a reduction in microbial activity or even death, thus naturally transitioning to the maturation stage (also known as the cooling stage). During this stage, microbial activity generally decreases, oxygen demand is greatly reduced, the composition of the compost pile tends to stabilize, and composting ends.

[0005] When fermenting manure into organic fertilizer, in addition to adding a suitable proportion of beneficial microorganisms, the addition of certain auxiliary materials is unavoidable. Livestock and poultry manure has a high moisture content, which can lead to excessive moisture during composting, resulting in insufficient permeability and hindering aerobic fermentation. Therefore, a certain proportion of auxiliary materials must be added to the manure, such as sawdust, wood shavings, cassava residue, sugarcane bagasse, straw powder, peanut shell powder, rice husk powder, and crushed vines. These materials adjust the carbon-ammonium ratio and moisture content of the raw materials, increase permeability, accelerate fermentation, and improve the quality of the finished organic fertilizer. Summary of the Invention

[0006] The present invention solves the technical problems existing in the prior art by providing an integrated device with automatic proportioning and feeding functions, oxygenation, heating, and stirring of mixed fermentation materials, as well as the ability to separate and process pig manure fermentation at different stages.

[0007] To achieve the above objectives, the present invention first provides a pig manure organic fertilizer fermentation device, which includes:

[0008] The housing has two sets of partitioning and layering components fixed inside, dividing the interior of the housing into a first cavity, a second cavity, and a third cavity from top to bottom.

[0009] The feed inlet is fixed to the upper part of the housing and includes a first feed inlet and a second feed inlet, which are respectively connected to the first cavity.

[0010] An automatic proportioning component and a feeding and metering device are provided. The automatic proportioning component is arranged in the first feed inlet and is used to measure the weight of pig manure. The feeding and metering device is arranged in the second feed inlet and is used to connect with the automatic proportioning component to calculate and release the corresponding proportion of fermentation auxiliary materials into the first cavity according to the weight of pig manure fed in.

[0011] A stirring assembly, which is introduced from the bottom of the shell and passes through the first cavity, the second cavity and the third cavity, is used to stir the fermentation mixture in the first cavity and the second cavity;

[0012] An oxygen injection assembly is arranged inside the stirring assembly and is used to inject oxygen into the fermentation mixture in the first chamber and the second chamber.

[0013] A temperature control component is arranged inside the shell surrounding the first and second cavities for heating the fermentation mixture in the first and second cavities.

[0014] An air pump, which is fixed to the outer wall of the housing and connected to the inside of the second cavity;

[0015] A pair of discharge ports, which are connected to the bottom of the third cavity.

[0016] Furthermore, a U-shaped plate is provided inside the third cavity, the U-shaped plate is inverted and fixed to the bottom of the shell, and a pair of discharge ports are respectively arranged on both sides of the U-shaped plate.

[0017] Furthermore, the automatic proportioning component includes: a telescopic rod, a fixed block, a movable plate, a weight sensor, and a fixed plate. The fixed plate is inverted L-shaped and fixed to the outer wall of the first feed inlet away from the second feed inlet. One end of the fixed plate extends above the first feed inlet, and the telescopic rod is fixed to the bottom of that end of the fixed plate and extends into the first feed inlet. The fixed block is fixed to the bottom of the inner wall of the first feed inlet. The movable plate is hinged to the fixed block, and the output end of the telescopic rod is fixed to the movable plate.

[0018] The weight sensor, telescopic rod, and material feeding metering device are respectively connected to the controller.

[0019] Furthermore, the stirring assembly includes: a first motor, a rotating shaft, and blades. The first motor is fixed to the bottom of the housing, and its output end extends into the housing and is fixedly connected to the rotating shaft. The rotating shaft passes through the first cavity, the second cavity, and the third cavity. A plurality of blades are fixed on the rotating shaft and are used to stir the fermentation mixture in the first cavity and the second cavity.

[0020] Furthermore, the partition layer assembly includes: a first annular outer cover, an outer edge, a second annular outer cover, a plurality of second motors, an arc plate, a first connecting rod, a second connecting rod, and an opening. The first annular outer cover is hollow inside, and its upper and lower ends both extend outward along the circumference and are fixedly connected to the inner wall of the shell through the outer edge.

[0021] The second annular outer cover is fitted onto the rotating shaft and rotatably connected to it. The outer surface of the second annular outer cover has multiple openings. Each arc plate has a first connecting rod and a second connecting rod fixedly connected to its two ends. The second connecting rod is inserted into and rotatably connected to the opening.

[0022] Multiple second motors are fixedly connected to the outside of the first annular outer cover. The output end of the second motor extends into the inside of the first annular outer cover and is fixedly connected to the first connecting rod. When the arc plate is in a flat state, the multiple arc plates are closely arranged to form a seamless partition layer inside the first annular outer cover.

[0023] Multiple second motors are respectively connected to the controller.

[0024] Furthermore, the oxygen injection assembly includes: an oxygen storage bottle, multiple one-way valves, and a cavity inside the rotating shaft. The oxygen storage bottle is arranged inside the cavity, and the multiple one-way valves are embedded in the surface of the rotating shaft. The oxygen storage bottle is connected to each one-way valve through a high-pressure pump.

[0025] Furthermore, the temperature control component includes: two sets of heating resistance wires, a pair of temperature sensors, and a protective shell. The pair of temperature sensors are respectively fixed on the side walls of the first cavity and the second cavity. Each temperature sensor is covered with a protective shell so that only the probe of the temperature sensor is exposed. The two sets of heating resistance wires are respectively embedded inside the shells surrounding the first cavity and the second cavity.

[0026] The temperature sensor and the heating resistance wire are respectively connected to the controller.

[0027] In addition, the present invention also provides a method for using a pig manure organic fertilizer fermentation device, characterized in that the method includes the following steps:

[0028] a. The pig manure to be fermented is poured into the first feed inlet and falls onto the movable plate. After being weighed and counted by the weight sensor, a signal is sent to the controller. The controller controls the telescopic rod to move downward so that the pig manure falls into the first chamber. Then the controller controls the feeding metering device to release the corresponding proportion of fermentation auxiliary materials into the first chamber according to the weight of the pig manure.

[0029] b. Start the first motor to drive the shaft and rotate the blades to stir the fermentation mixture in the first chamber. At the same time, start the high-pressure pump in the oxygen injection assembly in the first chamber to inject oxygen from the one-way valve into the fermentation mixture, promoting the growth of beneficial bacteria. The temperature sensor probe in the first chamber monitors the temperature of the fermentation mixture in real time. When the detected temperature is lower than the preset minimum temperature, the temperature sensor sends a signal to the controller. The controller controls the heating resistance wire in the shell around the first chamber to heat until the temperature detected by the temperature sensor reaches the preset minimum temperature. The fermentation mixture continues to ferment in the first chamber for 3-5 days under the above conditions.

[0030] c. Turn off the first motor to stop the shaft rotation, and simultaneously close the one-way valve to stop oxygen injection; start multiple second motors to rotate 90° forward simultaneously. The output of each second motor drives the first connecting rod to rotate, indirectly driving the arc-shaped plate and the second connecting rod to rotate synchronously, changing the arc-shaped plate from a flat state to a vertical state, causing the fermentation mixture in the first chamber to fall into the second chamber. Then, reverse the direction to reset the multiple second motors, indirectly driving the arc-shaped plate back to a flat state. Then, start the first motor again to drive the shaft to rotate the blades and stir the fermentation mixture in the second chamber. Start the air pump to extract the air from the second chamber, making the second chamber... The interior is in a near-vacuum state. The temperature sensor probe inside the second chamber monitors the temperature of the fermentation mixture in real time. When the detected temperature is lower than its preset minimum temperature, the temperature sensor sends a signal to the controller. The controller controls the heating resistance wires inside the shell around the second chamber to heat up until the temperature detected by the temperature sensor reaches the preset minimum temperature. At the same time, the high-pressure pump in the oxygen injection component inside the second chamber is activated to inject oxygen from the one-way valve into the fermentation mixture. By increasing the pressure inside the second chamber through both oxygen injection and temperature increase, the fermentation mixture is promoted. Under the above conditions, the fermentation mixture continues to ferment in the second chamber for 2-4 days.

[0031] d. After fermentation is complete, the second motor in the partition layering assembly at the bottom of the second chamber is started and rotated 90° in the forward direction, so that the fermented organic fertilizer in the second chamber flows out from the outlet; then the second motor is driven in the reverse direction to reset.

[0032] Furthermore, the temperature sensor in the first cavity is preset to a temperature of 60-75°C; the temperature sensor in the second cavity is preset to a temperature of 55-60°C.

[0033] Beneficial effects of the present invention

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. By setting up an automatic proportioning component and a feeding metering device, the device can automatically add an auxiliary mixture in proportion to the weight of pig manure, saving manpower.

[0036] 2. By setting up two layers of partitions and layering components, the inside of the device is divided into a first chamber and a second chamber for phased operation. The two parts correspond to the high-temperature period and the decomposition period, respectively. The external environmental conditions required for the two stages are further distinguished, which can further promote the degree of pig manure fermentation.

[0037] 3. The first chamber is equipped with oxygenation, stirring and heating components. During the high-temperature fermentation period, a large amount of oxygen is added and the design of synchronous movement with the rotating shaft increases the mixing and absorption rate of oxygen and fermentation mixture from the inside out. At the same time, the oxygen is output by a high-pressure pump so that the oxygen flow can help the fermentation mixture mix to a certain extent and reduce the stirring time.

[0038] The second chamber is equipped with oxygenation, stirring, and heating components, as well as a vacuum pump to create a near-vacuum state within it. By injecting a small amount of oxygen and increasing the temperature, the pressure within the second chamber is increased, promoting the fermentation of the mixture and improving fermentation efficiency.

[0039] 4. The fermentation mixture is assisted in heating by the temperature control component, so that the fermentation mixture in the first chamber is controlled between 60-75℃ and the fermentation mixture in the second chamber is controlled between 55-60℃. This not only promotes the reproduction and growth of beneficial bacteria, but also accelerates the fermentation process.

[0040] 5. The working components of the first and second chambers are independently separated, enabling the device to work continuously. When the fermented material in the first chamber is transferred to the second chamber, new feces can be added to the first chamber for a new round of fermentation, thus improving the working efficiency of the device.

[0073] In addition, the present invention also provides a method for using a pig manure organic fertilizer fermentation device, the method comprising the following steps:

[0074] a. The pig manure to be fermented is poured into the first feed port 21 and falls onto the movable plate 33. After being weighed and counted by the weight sensor 34, a signal is sent to the controller. The controller controls the telescopic rod 31 to move downward so that the pig manure falls into the first cavity 11.

At the same time, start the high-pressure pump in the oxygen injection component 7 in the first chamber 11 to spray oxygen from the one-way valve 72 to inject oxygen into the fermentation mixture, promoting the reproduction and growth of beneficial fermentation bacteria.

Under the above conditions, the fermentation mixture continues to ferment in the first chamber 11 for 3-5 days.

[0076] c. Turn off the first motor 51 to stop the rotation of the shaft 52, and simultaneously close the one-way valve 72 to stop oxygen injection; start multiple second motors 63 to rotate 90° forward simultaneously. The output of each second motor 63 drives the first connecting rod 65 to rotate, indirectly driving the arc plate 64 and the second connecting rod 66 to rotate synchronously, changing the arc plate 64 from a flat state to a vertical state, causing the fermentation mixture in the first chamber 11 to fall into the second chamber 12.

Start the air pump 9 to remove the air from the second chamber 12. When the mixture is extracted, the second chamber 12 is in a near-vacuum state. The temperature sensor 81 probe inside the second chamber 12 monitors the temperature of the fermentation mixture in real time. However, when the detected temperature is lower than its preset minimum temperature, the temperature sensor 81 sends a signal to the controller. The controller controls the heating resistance wire 83 inside the shell around the second chamber 12 to heat it until the temperature detected by the temperature sensor 81 reaches the preset minimum temperature. At the same time, the high-pressure pump in the oxygen injection component 7 inside the second chamber 12 is activated to spray oxygen from the one-way valve 72 and inject oxygen into the fermentation mixture. By increasing the pressure inside the second chamber 12 through both oxygen injection and temperature increase, the fermentation mixture is promoted.

[0077] d. After fermentation is complete, the second motor 63 in the partition layer assembly 6 at the bottom of the second chamber 12 is started to rotate 90° in the forward direction, so that the fermented organic fertilizer in the second chamber 11 flows out from the discharge port 10; then the multiple second motors 63 are driven in the reverse direction to reset.

5. A method of using the pig manure organic fertilizer fermentation device as described in claim 1, characterized in that, Includes the following steps: a. The pig manure to be fermented is poured into the first feed inlet (21) and falls onto the movable plate (33). After being weighed and counted by the weight sensor (34), a signal is sent to the controller. The controller controls the telescopic rod (31) to move downward so that the pig manure falls into the first cavity (11). Then the controller controls the feeding metering device (4) to release the corresponding proportion of fermentation auxiliary materials into the first cavity (11) according to the weight of the pig manure fed in. b. Start the first motor (51) to drive the shaft (52) to rotate each blade (53) to stir the fermentation mixture in the first chamber (11). At the same time, start the high-pressure pump in the oxygen injection component (7) in the first chamber (11) to spray oxygen from the one-way valve (72) to inject oxygen into the fermentation mixture and promote the reproduction and growth of beneficial bacteria. The temperature sensor (81) probe in the first chamber (11) monitors the temperature of the fermentation mixture in real time. However, when the detected temperature is lower than its preset minimum temperature, the temperature sensor (81) sends a signal to the controller. The controller controls the heating resistance wire (83) in the shell around the first chamber (11) to heat until the temperature sensor (81) detects that the temperature has reached the preset minimum temperature. The fermentation mixture continues to ferment in the first chamber (11) for 3-5 days under the above conditions. c. Turn off the first motor (51) to stop the rotation of the shaft (52), and at the same time close the one-way valve (72) to stop the oxygen injection; start multiple second motors (63) to rotate 90° forward simultaneously. The output end of each second motor (63) drives the first connecting rod (65) to rotate, indirectly driving the arc plate (64) and the second connecting rod (66) to rotate synchronously, so that the arc plate (64) changes from a flat state to a vertical state, so that the fermentation mixture in the first cavity (11) falls into the second cavity (12). Then, drive multiple second motors (63) in the reverse direction to reset, indirectly driving the arc plate (64) to return to a flat state. Then, start the first motor (51) again to drive the shaft (52) to drive each blade (53) to rotate and stir the fermentation mixture in the second cavity (12). Start the vacuum pump (9) to pump the second cavity (11) into the second cavity (12). 2) The air inside is extracted, so that the second chamber (12) is in a near vacuum state. The temperature sensor (81) probe inside the second chamber (12) monitors the temperature of the fermentation mixture in real time. When the detected temperature is lower than its preset minimum temperature, the temperature sensor (81) sends a signal to the controller. The controller controls the heating resistance wire (83) in the shell around the second chamber (12) to heat until the temperature detected by the temperature sensor (81) reaches the preset minimum temperature. At the same time, the high pressure pump in the oxygen injection component (7) inside the second chamber (12) is started to spray oxygen from the one-way valve (72) to inject oxygen into the fermentation mixture. The pressure inside the second chamber (12) is increased by both oxygen injection and heating, which promotes the fermentation of the fermentation mixture. The fermentation mixture continues to ferment in the second chamber (12) for 2-4 days under the above conditions. d. After fermentation is completed, the second motor (63) in the partition layer assembly (6) at the bottom of the second chamber (12) is started and rotated 90° in the forward direction, so that the fermented organic fertilizer in the second chamber (12) flows out from the outlet (10); then the second motor (63) is driven in the reverse direction to reset.

6. The method of using the pig manure organic fertilizer fermentation device according to claim 5, characterized in that, The temperature sensor (81) in the first cavity (11) is preset to a temperature of 60-75℃; the temperature sensor (81) in the second cavity (12) is preset to a temperature of 55-60℃.
