Description

Technical Field

[0001] The present invention relates to the technical field of fertilizer production, and in particular to a device and method for producing small molecule water-soluble fertilizer. Background Art

[0002] Small molecule water-soluble fertilizer is a compound fertilizer that can be completely dissolved in water. It contains various macroelements (such as nitrogen, phosphorus, potassium, etc.), trace elements (such as iron, manganese, zinc, copper, boron, molybdenum, etc.) required for plant growth, and some small molecule organic components (such as glucose, fructose, citric acid, phenol, vitamins, etc.). It is suitable for various fertilization methods such as drip irrigation, sprinkler irrigation, and foliar fertilization. The raw materials for producing small molecule water-soluble fertilizers can be urban fruit and vegetable waste. After being collected, screened and cleaned, the urban fruit and vegetable waste can be separated into cellulose, biomass separation liquid and impurities through biomass biochemical cracking and solid-liquid separation technology. Based on cellulose, ecological membranes, ecological pots, seedling trays and fruit seedling transplanting trays can be produced. Based on biomass separation liquid, organic small molecule water-soluble fertilizers such as humic acid hydroponic fertilizers, organic water solutions, microbial liquid fertilizers, liquid formula fertilizers and soil ecological improvers can be produced. Based on impurities, ecological and environmentally friendly new materials such as biomatrix, ecological seed blankets and ecological bags can be produced. Among them, organic small molecule water-soluble fertilizers can be degraded into fully water-soluble small molecule active substances using artificial bionic degradation technology. The degraded small molecule active substances are then concentrated to increase their nutrient concentration. According to the needs of the target crops, appropriate amounts of trace elements and other necessary ingredients are added to complete the production of small molecule water-soluble fertilizers.

[0003] A search revealed a Chinese invention patent, publication number CN 113135784 A, which discloses a system and process for aerobic fermentation and resource utilization of fruit and vegetable waste. The system includes a crushing device, a dehydration device, a high-temperature aerobic fermentation device, a drying device, and an exhaust gas and wastewater purification device. Compared to existing technologies, this Chinese invention patent, publication number CN 113135784 A, significantly reduces waste processing time and investment and operating costs, enabling harmless treatment and resource utilization of waste.

[0004] In the process of aerobic fermentation of the biomass mixture by the above-mentioned aerobic fermentation and resource utilization system for fruit and vegetable waste, in order to allow the biomass mixture and aerobic microbial agents inside the fermentation chamber to fully contact with oxygen to improve the fermentation efficiency, multiple air vents can be opened on the outside of the stirring blade for oxygenation. Since there is no need to continuously perform oxygenation and stirring operations, the oxygen supply and stirring frequency need to be adjusted according to the specific fermentation stage. Once the multiple air vents outside the stirring blade lose the oxygenation driving force and the rotational centrifugal force, the fermentation material can easily enter the interior of the air vent and cause it to be blocked, thereby affecting the subsequent oxygenation operation. Therefore, a small molecule water-soluble fertilizer production device is needed that can increase the oxygen contact rate by opening multiple air vents outside the stirring blade for oxygenation while being able to automatically seal the air vent.

The outside of the stirring shaft 322 is fixedly connected to an axially symmetrical stirring blade 323.

A conical sealing plug 806 is provided inside the upper ventilation space 803, and a piston rod 807 located inside the upper cavity 801 is provided on the top of the conical sealing plug 806. In the initial state, the deflection sealing plate 805 can be sealed at the bottom of the upper ventilation space 803 and abut against the conical sealing plug 806, thereby realizing the sealing of the upper ventilation space 803, i.e., the vent 327.

[0022] The working principle of this embodiment is as follows: Figure 1 As shown, the collected fruit and vegetable waste can be sorted and removed by the sorting and removing machine 100 to remove metals, plastics and glass in the fruit and vegetable waste to obtain pure fruit and vegetable waste, and then the clean fruit and vegetable waste after sorting can be cleaned, crushed and mixed by the cleaning and crushing machine 200 to obtain a uniform biomass mixture with a water content maintained between 50% and 65%, and then the treated biomass mixture can be aerobically fermented by the aerobic fermentation machine 300 to obtain biomass solid phase matter and liquid phase matter; When the treated biomass mixture is aerobic fermented by the aerobic fermentation machine 300, the biomass mixture and aerobic microbial inoculum are first added to the interior of the fermentation bin 310 through the feed pipe 311 and the additive pipe 312. Then, according to the fermentation demand, the biomass mixture and aerobic microbial inoculum in the fermentation bin 310 are stirred and oxygen is introduced into the interior through the stirring element 320 and the oxygen supply element 330. Then, the interior of the fermentation bin 310 is heated, the temperature and humidity, the oxygen concentration, and the pH value are monitored through the heating element 340, the monitoring element 350, and the exhaust element 360. The exhaust gas generated inside the fermentation bin 310 is purified and discharged. like Figure 4 and Figure 6 As shown, when the oxygen supply step is performed only by the oxygen supply member 330, the oxygen inside the oxygen supply tube 331 enters the interior of the ventilation cavity 326 through the fixed tube 325. The oxygen entering the ventilation cavity 326 enters the interior of the upper ventilation space 803 and abuts downward against the deflection blocking plate 805, causing the deflection blocking plate 805 to be abutted and opened, thereby allowing the oxygen to be discharged through the lower ventilation space 804, thereby achieving uniform oxygen supply during the fermentation process. like Figure 4 and Figure 6 As shown, when the stirring step is performed only by the stirring member 320, the driving end of the rotating shaft 321 starts to drive the stirring shaft 322 and the stirring blade 323 outside it to rotate and stir. When the stirring blade 323 rotates and stirs, the counterweight block 814 will stretch the telescopic reset rod B815 due to the action of centrifugal force and maintain the horizontal state of the deflection blocking plate 805. At the same time, the counterweight blocking block 808 and the counterweight frame 810 will stretch the telescopic reset rod A812 due to the action of centrifugal force and drive the deflection blocking plate 805 to slide to the other side of the lower cavity 802, so that the connecting hole 809 opened in the middle of the counterweight blocking block 808 is aligned with the upper ventilation space 803. Once the connecting hole 809 is aligned with the upper ventilation space 803, the conical sealing block 806 under the action of gravity and centrifugal force will move downward to block the connecting hole 809, and the vent hole 327 can be autonomously blocked during the stirring process by the rotating centrifugal force. like Figure 4 and Figure 6 As shown, when oxygen is supplied during stirring, the oxygen entering the ventilation cavity 326 enters the interior of the upper cavity 801 and abuts upward against the piston rod 807, so that the piston rod 807 drives the conical sealing plug 806 to move upward to open the communication hole 809, thereby allowing the oxygen to be discharged through the communication hole 809 and the lower ventilation space 804, thereby achieving uniform oxygen supply during stirring. Subsequently, the solid-phase and liquid-phase substances of the cracked biomass are separated by a solid-liquid separator 400 to obtain a biomass separation liquid. The separated biomass separation liquid is then artificially biomimetically degraded by a degradation processor 500 to obtain fully water-soluble small molecule active substances. The fully water-soluble small molecule active substances after biomimetic degradation are chemically analyzed by an analysis and replenishment machine 600 to determine the nutrient content, and the missing nutrients are supplemented according to the needs of the target crops to meet the requirements of full nutrition. Finally, the analyzed and supplemented small molecule water-soluble fertilizer is concentrated by a concentration processor 700 to form a small molecule water-soluble fertilizer that meets the growth needs of the target crops.

[0023] The main difference between this embodiment and the prior art is that: this embodiment can perform an oxygen supply step independently through the oxygen supply part 330 to achieve uniform oxygen supply during the fermentation process, and can perform a stirring step independently through the stirring part 320 to achieve uniform stirring during the fermentation process, and during the uniform stirring process, the upper ventilation space 803 can be blocked by the rotating centrifugal force of the anti-blocking part 800, that is, the autonomous blocking of the vent 327 during the stirring process can be achieved by the rotating centrifugal force, and the upper ventilation space 803 can be opened by the oxygen driving force during the uniform stirring process to achieve uniform oxygen supply during the stirring process, that is, the vent 327 will be opened only when the oxygen step is performed to prevent fermentation substances from entering the vent 327 and causing it to be blocked.

The circular filter press plate 902 moves downward to press down the biomass solid phase and separate the liquid phase. A liquid suction hose 905 is installed on the top of the circular filter press plate 902 through a mounting block 904. The liquid suction hose 905 is arranged on the top of the circular filter press plate 902 and is connected to the liquid suction port of the liquid suction pump 901. The separated liquid phase can be discharged through the liquid suction hose 905 and the liquid suction pump 901. The separator 900 also includes two bidirectional screws 906 rotatably connected to the interior of the fermentation bin body 310.

A linkage structure 910 is provided between the rotating shaft 321 and the two bidirectional screws 906. When the rotating shaft 321 drives the two bidirectional screws 906 to rotate through the linkage structure 910, the circular filter press plate 902 can be driven by the two threaded sleeves 907 to press down the biomass solid phase, separate the liquid phase, and reset the circular filter press plate 902. The linkage structure 910 includes a connecting bearing 911 embedded in the top of the fermentation bin 310, the rotating shaft 321 and the stirring shaft 322 are rotatably connected to the inner upper and inner lower parts of the connecting bearing 911 respectively, the top of the stirring shaft 322 is provided with a top rotating groove 912 rotatably connected to the end of the rotating shaft 321, the outer upper part of the connecting bearing 911 is rotatably connected to the linkage drum 913 sleeved on the outside of the rotating shaft 321, and a synchronous belt 914 is provided between the linkage drum 913 and the two bidirectional screws 906. The outer lower and outer upper parts of the rotating shaft 321 are both axially symmetrically provided with inner grooves 915, and the inner sides of the top rotating groove 912 and the linked rotating cylinder 913 are both axially symmetrically provided with one-way driving grooves 916. A connecting spring 917 is fixedly connected to the inner part of the inner groove 915. A lower one-way driving block 918 fixedly connected to the connecting spring 917 is slidably connected to the inner part of the lower inner groove 915. An upper one-way driving block 919 fixedly connected to the connecting spring 917 is slidably connected to the inner part of the upper inner groove 915. The rotating shaft 321 can drive the stirring shaft 322 to rotate clockwise through the lower one-way driving block 918 and the one-way driving groove 916, and can drive the linked rotating drum 913 to rotate counterclockwise through the upper one-way driving block 919 and the one-way driving groove 916. That is, when the rotating shaft 321 rotates clockwise, it can drive the stirring shaft 322 and the stirring blades 323 to stir the biomass mixture and aerobic microbial inoculant inside the fermentation bin 310. When the rotating shaft 321 rotates counterclockwise, it can drive the two bidirectional screws 906 to rotate so that the circular filter press plate 902 presses down the biomass solid phase and separates the liquid phase. The separator 900 also includes a centering transmitter 908 installed inside the fermentation tank body 310 and located above the through slot 903, and a centering receiver 909 installed on the top of the stirring blade 323. When the centering transmitter 908 and the centering receiver 909 are aligned, the stirring blade 323 can be driven to align with the through slot 903 through the rotating shaft 321. When the driving end of the rotating shaft 321 stops driving, the centering transmitter 908 and the centering receiver 909 are energized. Once the centering transmitter 908 and the centering receiver 909 are aligned, the rotating shaft 321 immediately stops rotating so that the stirring blade 323 is aligned with the through slot 903.

[0025] The working principle of this embodiment is as follows: based on the first embodiment, when the biomass mixture inside the fermentation bin 310 is stirred, the driving end of the rotating shaft 321 drives it to rotate clockwise, and the clockwise rotating rotating shaft 321 drives the stirring shaft 322 to rotate clockwise through the lower one-way driving block 918 and the one-way driving groove 916, so as to realize the clockwise stirring of the biomass mixture and aerobic microbial inoculant inside the fermentation bin 310 by the stirring blade 323. When the stirring operation is completed, the driving end of the rotating shaft 321 stops driving, and the centering transmitter 908 and the centering receiver 909 are energized. Once the centering transmitter 908 and the centering receiver 909 are aligned, the rotating shaft 321 immediately stops rotating so that the stirring blade 323 is aligned with the through groove 903. After the biomass mixture inside the fermentation bin 310 is fermented, the biomass solid phase and liquid phase can be separated by the separation element 900 and discharged separately. Specifically, the driving end of the rotating shaft 321 drives it to rotate counterclockwise, and the counterclockwise rotating rotating shaft 321 drives the linked rotating drum 913 to rotate counterclockwise through the upper unidirectional driving block 919 and the unidirectional driving groove 916. The counterclockwise rotating linked rotating drum 913 drives the two bidirectional screws 906 to rotate counterclockwise through the symmetrical synchronous belt 914, so that the two threaded sleeves 907 drive the circular filter press plate 902 to press down the biomass solid phase and separate the liquid phase. Then, the liquid pump 901 is started to make the liquid pump hose 905 discharge the separated liquid phase, and the solid phase that is pressed and compressed can be discharged through the discharge pipe 313 and the guide pump 314 at the bottom of the fermentation bin 310, so that the preliminary solid-liquid separation operation can be achieved. After the solid phase substances in the fermentation bin 310 are discharged, the rotating shaft 321 is continuously driven to rotate counterclockwise until the circular filter press plate 902 is restored upward to the initial position.

[0026] The main difference between this embodiment and the prior art is that: in this embodiment, the clockwise stirring operation of the stirring blade 323 can be achieved by driving the rotating shaft 321 clockwise, and the downward pressure of the circular filter press plate 902 can be achieved by driving the rotating shaft 321 counterclockwise, and the downward pressure of the circular filter press plate 902 can achieve the compaction of the biomass solid phase material and the separation of the liquid phase material. Subsequently, the compacted solid phase material and the separated liquid phase material can be discharged through the discharge pipe 313, the guide pump 314 and the liquid suction pump 901, so that the preliminary solid-liquid separation operation can be achieved, so as to carry out the subsequent precise solid-liquid separation operation.
