[0038] To address the shortcomings of existing fecal and urine waste treatment equipment, this disclosure provides a liquid organic fertilizer generation device.

[0039] like Figure 1 As shown, the liquid organic fertilizer generating equipment includes a mixing tank 1, a mixing device 12, a microbial agent adding device 11, a power unit, a filtration device, and a storage tank 5. The mixing tank 1 is configured to store liquid manure. The mixing device 12 is mounted on the mixing tank 1 and configured to uniformly mix the liquid manure inside the mixing tank 1. The microbial agent adding device 11 is configured to add microbial agents to the liquid manure. The power unit is configured to guide the liquid manure from the mixing tank 1 into the filtration device. The filtration device is connected to the mixing tank 1 and configured to filter impurities from the liquid manure, thus forming liquid organic fertilizer. The storage tank 5 is connected to the filtration device and configured to introduce the liquid organic fertilizer under the action of the power unit and store and age it.

[0040] Specifically, in practical applications, the mixing tank 1 can be directly built under the farm to collect liquid manure. The liquid manure is stirred evenly under the action of the mixing device 12. At the same time, the microbial agent adding device 11 set on the mixing tank 1 adds microbial agents to the liquid manure in the mixing tank 1 to deodorize and accelerate the decomposition of manure. The microbial agent rapidly decomposes the organic macromolecules of the liquid manure in an aerobic manner.

[0041] After the microbial agents decompose the liquid manure for a period of time, the liquid manure in the mixing tank 1 is then filtered through pipes by a power unit. Once the impurities in the liquid manure have been filtered out, the remaining portion is transferred to a storage tank for aging under the power unit's operation. After constant-temperature anaerobic fermentation and aging, it becomes liquid organic fertilizer that meets usage standards.

[0042] It should be noted that, in specific implementation, the aforementioned stirring device 12 can be a mixer or a stirring pump with stirring blades. The motor inside the mixer or stirring pump drives the stirring blades to rotate, ultimately ensuring that the liquid fecal matter in the mixing tank 1 is evenly mixed. The aforementioned microbial agent addition device can be a storage tank connected to the mixing tank 1 via a pipeline. The amount of agent added to this storage tank can be controlled manually or electronically, allowing the agent inside the storage tank to enter the mixing tank 1 through the pipeline and mix with the liquid fecal matter.

[0043] The liquid organic fertilizer generating equipment disclosed herein has a simple structure. It accelerates the decomposition of liquid manure by adding microbial agents to the liquid manure, and then filters the liquid manure to form liquid organic fertilizer that meets the standards.

[0044] In one embodiment of this disclosure, the microbial preparation is a 343 enzyme preparation. Specifically, the aforementioned 343 enzyme preparation is a three-bacterial symbiosis, namely 30% anaerobic bacteria, 30% aerobic bacteria, and 40% facultative anaerobic bacteria.

[0045] The 343 enzyme preparation separates the water from the liquid fecal waste. Under the action of the 343 enzyme preparation, the liquid fecal waste in the mixing tank 1 is rapidly decomposed. The heat released causes the temperature of the liquid fecal waste to rise rapidly. The increase in temperature and ventilation accelerate the evaporation of internal moisture, thereby reducing the volume of liquid fecal waste and achieving the reduction, stabilization and harmlessness of liquid fecal waste.

[0046] In one embodiment of this disclosure, the filtration device includes a primary filtration device 2 and a secondary filtration device 4. The primary filtration device 2 is connected to the mixing tank 1 and is configured to filter impurities in liquid sewage with a mesh size of 80 or less. The secondary filtration device 4 is configured to filter impurities in liquid sewage with a mesh size of 100 or less.

[0047] The liquid organic fertilizer generating equipment provided in this disclosure is equipped with a primary filtration device 2 and a secondary filtration device 4. The primary filtration device 2 is responsible for filtering impurities in the liquid manure with a mesh size of less than or equal to 80 mesh, such as 40 mesh impurities.

[0048] After the primary filtration device 2 performs initial filtration on the liquid fecal waste, removing larger impurities, the secondary filtration device 4 performs fine filtration on the liquid fecal waste. The secondary filtration device 4 mainly filters impurities with a mesh size of 100 or less from the liquid fecal waste, such as separating 90-mesh impurities from the liquid fecal waste.

[0049] In actual installation, the primary filtration device 2 can be a microfilter using an 80-mesh filter, and the secondary filtration device 4 can be a dual-series filter using a 100-mesh filter.

[0050] The liquid organic fertilizer generating equipment provided in this disclosure is equipped with a dual filtration device, which not only helps to reduce the working pressure of a single filtration device, but also effectively ensures the working efficiency of the filtration device.

[0051] In addition, it should be noted that the aforementioned power unit includes delivery pumps installed at different locations in the liquid organic fertilizer generation equipment. By installing multiple delivery pumps, the entire liquid organic fertilizer generation equipment can be guaranteed to continuously and stably deliver liquid organic fertilizer.

[0052] In one embodiment provided in this disclosure, the power unit includes a circulation pump 13 disposed on a mixing tank 1 and a feed pump 3 disposed between a primary filter device 2 and a secondary filter device 4. The circulation pump 13 transports the liquid sewage in the mixing tank 1 to the primary filter device 2 for initial filtration. The liquid sewage after initial filtration is then transported to the secondary filter device 4 and subsequent devices by the feed pump 3.

[0053] In practical applications, to meet specific needs, the liquid organic fertilizer generating equipment also needs to further decompose the liquid organic fertilizer in the storage tank 5. Therefore, in one embodiment of this disclosure, the liquid organic fertilizer generating equipment also includes a reaction vessel 6, which is connected to the outlet of the storage tank 5. The reaction vessel 6 is configured to introduce liquid organic fertilizer and heat it under the action of a power unit.

[0054] The outlets of the aforementioned reactor 6 and storage tank 5 are connected via pipes. Under the action of a power unit, the liquid organic fertilizer in storage tank 5 flows into reactor 6. In order for the microbial community in the 343 enzyme preparation in reactor 6 to better decompose the liquid organic fertilizer, it is necessary to add additional 343 enzyme preparation to reactor 6. In addition, it is also necessary to provide a suitable temperature for the microbial community.

[0055] Specifically, in one embodiment of this disclosure, the liquid organic fertilizer generating device further includes a control device 61, which is communicatively connected to a temperature testing device 62 inside the reactor 6 and is configured to adjust the temperature of the liquid organic fertilizer inside the reactor 6 according to the temperature data obtained by the temperature testing device 62, so that it reaches a preset temperature threshold.

[0056] In actual use, the temperature testing device 62 inside the reactor 6 can detect the temperature of the liquid organic fertilizer in real time. The user compares the temperature data obtained by the temperature testing device 62 with the preset temperature threshold, and then adjusts the temperature inside the reactor 6 through the control device 61 so that the temperature of the liquid organic fertilizer inside the reactor 6 is suitable for the microbial community of the 343 enzyme preparation to decompose it.

[0057] More specifically, in one embodiment of this disclosure, a water pipe 63 is provided around the reactor 6, and the control device 61 controls the water temperature in the water pipe 63 to bring the liquid organic fertilizer in the reactor 6 to a preset temperature threshold. That is, the liquid organic fertilizer generating equipment provided in this disclosure heats the liquid organic fertilizer in the reactor 6 using a water-heating method, making the temperature change of the liquid organic fertilizer more stable and avoiding sudden cooling or heating, which is beneficial to the survival of the microbial community in the 343 enzyme preparation.

[0058] For example, a serpentine water pipe 63 is laid around the perimeter of the reactor 6, with its surface in contact with the outer wall of the reactor 6 to facilitate heat transfer. After the control device 61 controls the water temperature inside the water pipe 63 to rise, the water temperature is transferred through the outer wall of the water pipe 63 and the outer wall of the reactor 6 to the liquid organic fertilizer inside the reactor 6, ultimately raising the temperature of the liquid organic fertilizer to the preset temperature threshold.

[0059] In one embodiment of this disclosure, the preset temperature threshold is 45°C to 50°C. In practical applications, the user first raises the water temperature in the water supply pipe 63 using the control device 61, and stops heating when the water temperature in the water supply pipe 63 reaches approximately 86°C. Since the water supply pipe 63 is in contact with the reaction vessel 6, the temperature of the water inside the water supply pipe 63 can be transferred to the liquid organic fertilizer inside the reaction vessel 6 through the water supply pipe 63 and the surface of the reaction vessel 6.

[0060] After the water temperature in the water pipe 63 is stopped from being heated, the liquid organic fertilizer in the reactor 6 continuously absorbs the heat from the water pipe 63, eventually reaching a temperature range of 45°C to 50°C. Within this temperature range, the activity of the microbial community can be guaranteed, allowing the microbial community to better decompose the liquid organic fertilizer, while also promoting the reproduction of the microbial community.

[0061] In one embodiment of this disclosure, the liquid organic fertilizer generating device further includes a microbial acclimatization box 7, which is connected to the reaction vessel 6. The microbial acclimatization box 7 is equipped with a microbial community retention unit, which is configured to retain the microbial community in the liquid organic fertilizer.

[0062] Considering that in practical applications, after the liquid organic fertilizer is continuously sent into storage tank 5 and then continuously exported for packaging, this liquid organic fertilizer will continuously take away the microbial community in the 343 enzyme preparation, resulting in the waste of the microbial community.

[0063] Therefore, the liquid organic fertilizer generating equipment provided in this disclosure is also equipped with a microbial acclimatization box 7, in which a microbial community retention unit is set up. When the liquid organic fertilizer flows through the microbial acclimatization box 7, the microbial community of the 343 enzyme preparation in the liquid organic fertilizer will reside on the microbial community retention unit and will no longer flow with the liquid organic fertilizer to the subsequent devices.

[0064] Specifically, in practical applications, the aforementioned microbial retention unit can be strips of cloth suspended on the side wall of the microbial acclimatizer. These strips are soaked in liquid organic fertilizer, providing a habitat for the microorganisms. When the liquid organic fertilizer in the microbial acclimatizer is discharged and bottled, most of the microorganisms of the 343 enzyme preparation will remain on these strips of cloth. When the next batch of liquid organic fertilizer is introduced into the microbial acclimatizer, the microorganisms of the 343 enzyme preparation remaining on the strips of cloth can continue to decompose subsequent batches of liquid organic fertilizer.

[0065] The liquid organic fertilizer generation equipment disclosed herein improves the utilization rate of the microbial community in the 343 enzyme preparation by setting up a microbial acclimatization box 7, and effectively reduces the decomposition cost.

[0066] In one embodiment of this disclosure, the liquid organic fertilizer generating device further includes a filling machine 9, which is connected to a microbial acclimatization box 7 and is configured to collect and fill liquid organic fertilizer.

[0067] In practical applications, the finished liquid organic fertilizer also needs to be packaged and then transported to various locations that require it. Therefore, in one embodiment of this disclosure, the liquid organic fertilizer generating equipment also includes a filling machine 9, which is connected to the microbial acclimatization box 7 and is configured to collect and fill the liquid organic fertilizer.

[0068] The liquid organic fertilizer generating equipment disclosed herein completes the collection of liquid organic fertilizer by setting up a filling machine 9, making the entire process of the liquid organic fertilizer generating equipment more complete.

[0069] In practical applications, the long pipeline between the filling machine 9 and the microbial acclimatization box 7 often leads to a loss of pressure provided by the power unit, resulting in insufficient suction of the filling machine 9, which in turn prevents the filling machine 9 from continuously filling and packaging liquid organic fertilizer.

[0070] Therefore, in one embodiment of this disclosure, a transfer box 8 is provided between the filling machine 9 and the microbial acclimatization box 7. The transfer box 8 is configured to store the liquid organic fertilizer between the filling machine 9 and the microbial acclimatization box 7. The liquid organic fertilizer generating equipment provided by this disclosure, by providing a transfer box 8 between the filling machine 9 and the microbial acclimatization box 7, avoids the problem of pressure loss caused by pipeline processes, which could lead to a continuous supply of liquid organic fertilizer to the filling machine 9, thus enabling the filling machine 9 to operate more stably.

[0071] To facilitate understanding of the liquid organic fertilizer generating equipment provided in this disclosure, the following description will be based on an application scenario.

[0072] A mixing tank 1 is located underground in the breeding area to collect liquid manure. A mixing device 12 is installed on the mixing tank 1 to agitate the liquid manure inside. During the agitation process, a microbial agent addition device adds 343 enzyme preparation to the mixing tank 1. Other nutrients, such as nitrogen and potassium, can also be added to the mixing tank as needed.

[0073] After the liquid feces in the mixing tank is decomposed and fermented by the 343 enzyme preparation for a period of time, the liquid feces is transported to the primary filtration device 2 through the pipeline under the action of the power unit. The primary filtration device 2 filters out impurities with a mesh size of 80 or more in the liquid feces. The remaining liquid feces enters the secondary filtration device 4. After the secondary filtration device 4 removes impurities with a mesh size of 100 or less in the liquid feces, the remaining part enters the reaction vessel 6 through the storage tank under the action of the power unit.

[0074] The user adjusts the temperature inside the reactor 6 using the control device 61, so that the temperature of the liquid organic fertilizer inside the reactor 6 reaches 45°C, thereby accelerating the decomposition rate of the microbial community in the 343 enzyme preparation.

[0075] Finally, the liquid organic fertilizer in reactor 6 passes through microbial acclimatization box 7 and then enters filling machine 9 for filling. During this process, the microbial community of the 343 enzyme preparation in microbial acclimatization box 7 is retained on the microbial community retention unit, continuing to decompose the next batch of liquid organic fertilizer.

[0076] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
