Description

Technical Field

[0001] The present invention relates to the technical field of organic fertilizer production, in particular to an organic fertilizer and an organic fertilizer processing technology. Background Art

[0002] Kitchen waste, a significant component of municipal solid waste, is rich in organic matter and a high-quality raw material for producing organic fertilizer. However, kitchen waste is often contaminated with significant amounts of oil and grease, which originates from a wide range of sources, including household cooking waste and leftover cooking oil from the restaurant industry. In traditional kitchen waste-to-organic fertilizer processing, this oil and grease enters the fermentation system along with the waste, negatively impacting the fermentation process. Microorganisms play a key role in the fermentation process, breaking down organic matter to produce the active ingredients in fertilizer. However, oil and grease form an oil film in the fermentation system, which blocks oxygen from entering the system. Many of the microorganisms involved in kitchen waste fermentation are aerobic, such as Bacillus and actinomycetes, and require sufficient oxygen for respiration and metabolic activity. Insufficient oxygen supply severely inhibits microbial activity, slowing growth and reproduction, and even potentially killing some microorganisms. The presence of oil and grease also compromises the quality of the fermentation product. During the fermentation process, oils and fats may undergo hydrolysis and oxidation reactions, producing some substances with pungent odors, such as short-chain fatty acids, aldehydes, ketones, etc. These odorous substances not only affect the user experience of organic fertilizers, but may also have adverse effects on soil and crops. In addition, oils and fats will also affect the content of organic matter and nutrient ratios in the fermentation products, reducing the fertilizer efficiency of organic fertilizers. At present, although some oil separation technologies are applied to the field of kitchen waste treatment, most of them have problems such as poor separation effect, high cost or complicated operation. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the present invention provides an organic fertilizer and an organic fertilizer processing process, which has the beneficial effect of being able to separate the oil and fat in kitchen waste, preventing the oil and fat mixed in the waste from reducing the activity of microorganisms in the fermentation system during the fermentation process, and increasing the degradation rate of organic matter, thereby improving the fermentation efficiency.

DETAILED DESCRIPTION

[0021] like Figures 1 to 4 As shown:

[0022] An organic fertilizer processing device includes a barrel body 101 with an electric heating plate installed on the outer wall. The core of the barrel body 101 is sealed and slidably connected to a core barrel 102. The lower end of the core barrel 102 is fixedly connected to a base frame 103. Electric push rods 104 are fixedly connected between the two ends of the base frame 103 and the bottom surface of the barrel body 101. The upper end of the barrel body 101 is covered with a top cover 105. The lower end of the core barrel 102 is connected to an oil drain pipe with a valve. The bottom of the barrel body 101 is fixedly connected to a plurality of supporting legs. A collection box can be placed at the lower end of the oil drain pipe to collect discharged water and grease.

[0023] After opening the top cover 105, the crushed kitchen waste is put into the barrel body 101, water and fermentation bacteria are added to the barrel body 101, and the top cover 105 is put back on the barrel body 101. The electric heating plate is energized to heat the water and garbage in the barrel body 101, promoting the dissolution of the oil in the kitchen waste. The dissolved oil will float on the upper layer of the liquid surface and separate from the garbage, thereby realizing the separation of oil and garbage, avoiding the oil mixed in the garbage during the fermentation process to reduce the activity of microorganisms in the fermentation system, and increasing the degradation rate of organic matter, thereby improving the fermentation efficiency.

[0024] The telescopic ends of the two electric push rods 104 are extended to move the base frame 103 downward. The base frame 103 then moves the hollow cylinder 201 downward, causing the upper end of the core barrel 102 to move below the liquid surface. This allows the grease floating on the upper surface of the liquid to enter the core barrel 102, removing the solid grease from the food waste. This prevents the solid grease from entrapping the organic matter in the food waste, hindering microbial contact and decomposition. After the grease is removed, the organic matter is more easily degraded, improving fermentation efficiency and further reducing the impact of animal fat on the fermentation process.

[0025] After the valve on the oil drain pipe at the lower end of the core barrel 102 is opened, the grease collected in the core barrel 102 is discharged; after the grease is discharged from the core barrel 102, the core barrel 102 is continued to be controlled to move downward, and the excess water in the barrel body 101 enters the core barrel 102 and is discharged from the core barrel 102. The remaining garbage in the barrel body 101 is fermented by the fermentation bacteria, and the electric heating plate heats the garbage to promote the fermentation process. After the fermentation is completed, the top cover 105 is opened to facilitate the removal of the organic fertilizer.

[0026] like Figures 6 to 7 As shown:

[0027] The core of the top cover 105 is inserted with a hollow cylinder 201. The upper and lower ends of the hollow cylinder 201 are respectively connected to an air inlet pipe 202 and two air guide pipes 203. The lower ends of the two air guide pipes 203 are respectively connected to an air outlet pipe 204. The bottom surfaces of the two air outlet pipes 204 are each equipped with a plurality of air outlet nozzles.

[0028] An external pipe carrying high-pressure hot air is sealed and rotatably connected to the air inlet pipe 202. The high-pressure hot air enters through the air inlet pipe 202, flows through the hollow cylinder 201 and two air guide pipes 203, and is ejected from the outlet nozzles on the two outlet pipes 204. The hot air jets into the water, heating the water and the garbage. This further heats the garbage and water, promoting the melting of solid fats in the food waste and increasing the speed of fat separation. Furthermore, because the hot air jet has a certain high-pressure jet force, food waste in the water will not block the outlet nozzles.

[0029] like Figures 5 to 6 As shown:

[0030] The top cover 105 is provided with a motor I 301 , the output shaft of the motor I 301 is fixedly connected to a gear I 302 , and the intake pipe 202 is fixedly connected to a gear II 303 which is meshed and transmission-connected with the gear I 302 ;

[0031] When motor I 301 is started, it drives gear I 302 to rotate. Gear I 302 drives gear II 303 to rotate. Gear II 303 drives the air inlet pipe 202 and the hollow cylinder 201 to rotate. The hollow cylinder 201 drives the two air guide pipes 203 and the two air outlet pipes 204 to perform circular motion. This causes the hot air jets from the two air outlet pipes 204 to evenly affect the garbage and water in the circumferential direction, thereby uniformly heating the garbage and water and fully dissolving the grease. Simultaneously, the two air outlet pipes 204 stir the garbage during rotation, promoting the separation of dissolved grease from the garbage.

[0032] On this basis, since the external pipe through which the high-pressure hot air flows is rotatably connected to the air intake pipe 202, the rotation of the air intake pipe 202 will not cause rotational interference with the external pipe.

[0033] like Figure 8 As shown:

[0034] A spiral plate I 209 with filter holes is fixedly connected to the two air outlet pipes 204; the two air outlet pipes 204 drive the two spiral plates I 209 to perform circular motion synchronously, and the two spiral plates I 209 stir the garbage, stir and disperse the grease solidified in large pieces of debris and solidified into agglomerates, making it easier to separate the grease from the garbage, thereby improving the grease separation efficiency.

[0035] Secondly, the stirring of the stirring blades pushes the hot air flow ejected from the air outlet pipe 204 evenly into the water and garbage, further heating the garbage and grease more evenly, accelerating the melting of the grease, and thus separating it from the garbage more effectively.

[0036] Furthermore, the spiral plate I 209, with its helix angle, generates axial thrust during rotation, pushing the food waste to circulate axially along the barrel body 101, preventing local overheating or clumping. The helix angle of the spiral plate I 209 also allows the waste to be mixed radially and propelled axially within the barrel body 101, creating a circulation pattern that heats the waste more evenly and effectively.

[0037] After heating, the viscosity of the grease decreases and the fluidity is good. The spiral structure of the spiral plate I 209 makes it easier for the grease to float to the surface during the stirring process. Because the density of grease is smaller than that of water, it is easier to stratify after heating. The design of the spiral rise angle is consistent with the floating direction of the grease, which promotes the aggregation and separation of the grease.

[0038] like Figures 5 to 6 As shown:

[0039] Two side frames 205 are symmetrically fixed to the top cover 105, and electric push rods II 206 are fixed to the two side frames 205. The telescopic ends of the two electric push rods II 206 are fixed to shift forks 207. The upper end of the hollow cylinder 201 is provided with an annular groove 208, and the two shift forks 207 are symmetrically inserted into the annular groove 208. The motor I 301 is fixed to one of the shift forks 207 through the motor frame.

[0040] The extension or retraction of the telescopic ends of the two electric push rods II 206 drives the two forks 207 to move up and down. The two annular grooves 208 cooperate with the annular grooves 208 to drive the hollow cylinder 201 to move up and down. The hollow cylinder 201 drives the two air outlet pipes 204 and the two spiral plates I 209 to move vertically, thereby heating and stirring the garbage and water at different levels, so that the grease mixed in the garbage is separated more thoroughly.

[0041] like Figure 6 and 10 As shown:

[0042] Two arc-shaped rods 401 are symmetrically fixed between the two air outlet pipes 204 , and a crossbeam 402 is slidably connected to each of the two arc-shaped rods 401 . A spiral plate II 403 having the same shape as the spiral plate I 209 is fixed to each of the two crossbeams 402 .

[0043] The two air guide tubes 203 drive the two cross beams 402 and the two spiral plates II 403 to perform circular motion synchronously with the two spiral plates I 209 through the two arc rods 401, thereby increasing the number of stirring plates, improving the effect of stirring the garbage, and thus improving the grease separation efficiency.

[0044] like Figures 9 to 10 As shown:

[0045] The intake pipe 202 is rotatably connected to a ring gear 406, and two straight rods 407 are symmetrically fixed to the ring gear 406. Both straight rods 407 are fixed to a column 404. The hollow cylinder 201 is symmetrically provided with two arcuate slots 405 that are not connected to the interior thereof. The two columns 404 pass through the two arcuate slots 405 and are fixed to the two crossbeams 402. The top cover 105 is fixedly connected to a motor II 304 driven by a battery. The output shaft of the motor II 304 is fixedly connected to a gear III 305 that meshes with the ring gear 406.

[0046] A T-shaped slot is provided on the inner side of the crossbeam 402, so that the crossbeam 402 can slide on the arc rod 401 around the extension direction of the arc rod 401. Therefore, when it is necessary to squeeze the garbage, the control motor II 304 is started to drive the gear III 305 to rotate back and forth. The gear III 305 drives the gear ring 406 to rotate back and forth a certain angle by engaging with the gear ring 406. The gear ring 406 drives the column rod 404 to slide back and forth in the arc groove 405 through the straight rod 407. The column rod 404 drives the spiral plate II 403 to rotate back and forth. When the spiral plate II 403 located between the two spiral plates I 209 rotates back and forth, the garbage located between the spiral plates I 209 and II 403 is continuously squeezed by the adjacent spiral plates II 403 and I 209 when the spiral plate II 403 rotates back and forth, thereby fully squeezing out the grease mixed in the garbage and promoting efficient grease separation.

[0047] The motor II 304 is driven by a battery to prevent the electric wire from being entangled when the motor II 304 rotates along with the hollow cylinder 201 .

[0048] Furthermore, the outer ends of the two straight rods 407 are fixedly connected to curved plates 408 that can block the curved grooves 405. The two curved plates 408 prevent hot air from escaping from the barrel body 101 through the two curved grooves 405. Furthermore, when the two pillars 404 slide back and forth within the two curved grooves 405, the two curved plates 408 alternately block the two curved grooves 405. Even if the curved grooves 405 are momentarily exposed and heat is released, it will not significantly affect the overall situation. Furthermore, the curved plates 408 can be controlled to rotate to expose the curved grooves 405, thereby venting the space within the barrel body 101.

[0050] Step 1: Crush the kitchen waste and put it into the barrel 101, and add water and fermentation bacteria into the barrel 101;

[0051] Step 2: heating the water and garbage in the barrel 101 through the electric heating plate;

[0052] Step 3: The high-pressure hot air flow is introduced through the air inlet pipe 202, flows through the hollow cylinder 201 and the two air guide pipes 203, and is ejected from the two air outlet pipes 204;

[0053] Step 4: The hollow cylinder 201 drives the two spiral plates I 209 and the two spiral plates II 403 to stir and squeeze the kitchen waste in the water;

[0054] Step 5: Control the core barrel 102 to move downward to below the liquid surface, and the grease floating on the upper surface of the liquid is discharged from the core barrel 102; then control the core barrel 102 to continue moving downward to discharge excess water;

[0055] Step 6: The garbage in the barrel 101 is fermented by the fermentation bacteria, and the fermenting organic fertilizer is stirred by the two spiral plates II 403 and the two spiral plates I 209, and the top cover 105 is opened to facilitate the removal of the organic fertilizer.
