Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of organic fermentation fertilizer preparation, in particular to a preparation method of organic fermentation fertilizer. BACKGROUND

[0002] The organic fermentation fertilizer is a kind of green fertilizer rich in organic matter and various trace elements, which is made of organic waste such as livestock and poultry manure, crop straw and kitchen waste as main raw materials through microbial aerobic fermentation, deodorization and composting treatment. It is widely used in agricultural planting, soil improvement and landscaping fields. The preparation process mainly includes the following steps: raw material pretreatment, ingredient mixing, composting fermentation, post-mature aging and screening packaging. Among them, the aerobic fermentation in the composting reactor is the core link, which needs effective oxygen supply, uniform inoculation and sufficient material mixing to ensure efficient microbial degradation of organic matter and stable composting.

[0003] However, the aerobic fermentation process in the existing composting reactor still has the following problems: 1. The existing bottom fixed aeration system can only penetrate the stack from bottom to top in one direction, resulting in excessive oxygen supply and even over-drying of the lower layer of material, while the upper layer and the middle part of the area have serious airflow attenuation and oxygen distribution is thin, which is easy to form anaerobic micro area. At the same time, the single airflow path and lack of horizontal disturbance make it difficult to achieve uniform oxygen supply and effective mixing of the whole cross section of the stack, which seriously affects the uniformity of fermentation and microbial activity.

[0004] 2. In order to alleviate the uneven gas supply and material hardening, the traditional process needs to rely on periodic mechanical turning to realize mixing and re-oxygenation, but the turning operation interval is long and the disturbance range is limited, which is difficult to break the material stratification and adhesion structure in real time, and also easy to cause uneven mixing of materials, which directly affects the stability and reaction rate of subsequent fermentation.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0023] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0024] The following is based on Figure 1 - Figure 12 The preparation method of the organic fermented fertilizer provided by the embodiments of the present application is described.

[0025] Embodiment one, the present embodiment refers to Figure 1 - Figure 9 The preparation method of the organic fermented fertilizer comprises the following steps: Step one: collect the main organic raw materials and auxiliary materials, mix after impurity removal and crushing, adjust the carbon-nitrogen ratio and water content, and obtain pretreated materials; Step two: uniformly deliver the pretreated materials into the slot-type compost reactor 1 to form a straw-shaped pile; Step three: set dynamic injection device 2 inside the groove composting reactor 1, which can inject compressed air and complex microbial inoculant into the interior and lateral of the pile at multiple angles, so that the gas and inoculant can penetrate the material layer and achieve uniform dispersion, thereby activating microbial activity and maintaining efficient aerobic fermentation; Step four: after controlling the temperature of the pile for a period of time, enter the maturation stage to obtain finished organic fertilizer.

[0026] As shown in Figure 2 and Figure 3 , the dynamic injection device 2 in step three includes two rectangular distribution cavities 21 arranged symmetrically along the length of the composting reactor 1, which are connected to the external injection system 3 through flexible conveying pipes. The pipes have good axial extensibility and bending adaptability, can freely stretch and shrink without affecting fluid tightness, and the injection system 3 can send compressed air and complex microbial inoculant into the rectangular distribution cavities 21 in a timely and quantitative manner according to process requirements. In addition, the composting reactor 1 is also provided with a separate existing gas injection device at the bottom for auxiliary bottom oxygen supply, which cooperates with the dynamic injection device 2 to achieve uniform aeration and biological inoculation of the whole cross section of the pile.

[0027] As shown in Figure 2 and Figure 3 , the rectangular distribution cavities 21 can move back and forth along the length of the composting reactor 1 to achieve full coverage injection of the pile. During the movement, the flexible pipes stretch or shrink synchronously to ensure continuous and stable feeding. Specifically, the upper ends of the left and right rectangular distribution cavities 21 are each provided with forward and backward distributed connecting blocks 211. The left and right connecting blocks 211 on the front side are slidingly installed on the same guide column 212, which is installed on the upper end of the groove body of the composting reactor 1. The guide column 212 provides support and linear guidance for the movement of the two rectangular distribution cavities 21. The left and right connecting blocks 211 on the rear side are threadedly installed on the same bidirectional screw rod 213, which is rotatably installed on the upper end of the groove body of the composting reactor 1. The right end of the bidirectional screw rod 213 is connected to the output shaft of the driving motor 214, which is fixedly installed on the groove body of the composting reactor 1.

[0028] When working, the driving motor 214 is started and drives the bidirectional screw rod 213 to rotate. Since the left and right connecting blocks 211 on the rear side are respectively engaged with the left and right threaded segments of the bidirectional screw rod 213, the two rectangular distribution cavities 21 can move synchronously towards or away from each other along the length of the composting reactor 1. By controlling the forward and reverse rotation of the driving motor 214, the reciprocating motion of the left and right rectangular distribution cavities 21 within the set stroke range can be realized, thereby continuously and uniformly disturbing the material and injecting the inoculant in the full length area of the pile.

[0029] As shown in Figure 3 and Figure 4As shown, two groups of spraying assemblies are symmetrically arranged in the rectangular material cavity 21, and the spraying assemblies can move synchronously with the rectangular material cavity 21. The spraying assembly includes a rotating spray pipe 22 capable of reciprocating rotation, which is connected with the rectangular material cavity 21. The rectangular material cavity 21 and the rotating spray pipe 22 form a regular staggered grid-shaped material feeding area in space, which can effectively break the overall continuity of the pile and prevent the formation of sticky strips, and significantly improve the material dispersibility.

[0030] During the reciprocating movement of the rectangular material cavity 21, the rotating direction of the rotating spray pipe 22 is opposite in the forward stroke and the return stroke, so that the spraying trajectory is staggered in the pile, realizing the complementarity of the coverage area, effectively avoiding the coverage blind area. The rectangular material cavity 21 and the rotating spray pipe 22 are both provided with uniformly distributed feeding holes 222 for synchronously introducing compressed air and composite microbial agents into the pile. Combined with the movement of the rectangular material cavity 21 and the rotation of the rotating spray pipe 22, a multi-angle and dynamic penetrating uniform spraying is formed, which significantly improves the material mixing efficiency and uniformity.

[0031] It should be noted that the feeding hole 222 can adopt a one-way conduction structure such as an embedded check bevel or a tapered outlet. The medium can only be sprayed out from the inside to the outside, and it is difficult to enter the sundries in the opposite direction, so that blockage rarely occurs.

[0032] Among them, as shown in Figure 3 - Figure 6 The rotating spray pipe 22 is composed of four swing pipes 221 arranged in a cross shape and connected with each other. The connection between each swing pipe 221 and the interface between the swing pipe 221 and the rectangular material cavity 21 are connected by a deformable sealing joint. The joint allows the swing pipe 221 to deflect during rotation while maintaining fluid sealing at all times, ensuring that the swing pipe 221 is always connected with the inside of the rectangular material cavity 21 during rotation. Thus, the compressed air and composite microbial agents injected into the rectangular material cavity 21 can naturally flow into the rotating spray pipe 22 and be synchronously sprayed out through the feeding hole 222, implementing a stirring and mixing type of rotating and inclined spraying on the material located in the rectangular material cavity 21 area, which has the functions of disturbance, loosening and uniform mixing.

[0033] As shown in Figure 5 - Figure 9As shown, in order to realize the reciprocating rotation of the rotating nozzle 22, a fixed rod 223 is connected between the left and right inner walls of the compost reactor 1, the fixed rod 223 passes through the central area of the rotating nozzle 22 and is in sliding fit with the rotating nozzle 22, two groups of control grooves are symmetrically arranged on the outer circumferential surface of the fixed rod 223, each group of control grooves includes two wave-shaped grooves 224 which are symmetrically arranged along the circumferential direction of the fixed rod 223, the wave-shaped grooves 224 are continuously undulating along the axial direction of the fixed rod 223, the rotating nozzles 22 on the left and right sides which are close to each other are both provided with an annular connecting plate 225, the inner annular surface of the annular connecting plate 225 is fixedly connected with a moving ring plate 226 which is sleeved on the outer side of the fixed rod 223, and the inner side of the moving ring plate 226 is provided with a matching rod 227 which is in sliding fit with the control groove.

[0034] In the process that the rotating nozzle 22 moves along the length direction of the compost reactor 1 with the rectangular material cavity 21, the annular connecting plate 225 and the moving ring plate 226 are in synchronous translation, at this time, the matching rod 227 fixed to the inner side of the moving ring plate 226 is always embedded in and slides along the wave-shaped groove 224 on the fixed rod 223, since the wave-shaped groove 224 is continuously undulating along the axial direction of the fixed rod 223, the matching rod 227 is guided by the profile of the wave-shaped groove 224 in the sliding process, and periodic circumferential displacement changes are generated, so as to drive the moving ring plate 226 and the annular connecting plate 225 fixedly connected therewith to make circumferential reciprocating swing around the fixed rod 223, and finally drive the rotating nozzle 22 to realize reciprocating rotation movement.

[0035] As shown in the figure, Figure 7 - Figure 9 In order to realize the differential control of the swing direction of the rotating nozzle 22 in the outward and return strokes, two semicircular shielding plates 228 are sleeved on the outer periphery of the fixed rod 223, the semicircular shielding plates 228 are rotationally connected with the inner walls of the compost reactor 1, each semicircular shielding plate 228 covers the outer side of a group of wave-shaped grooves 224 on the corresponding side, shields one of the wave-shaped grooves 224, and makes the matching rod 227 only be able to slide with the other wave-shaped groove 224 which is not shielded, so as to ensure the accuracy and reliability of the motion trajectory switching, the shielding positions of the left and right semicircular shielding plates 228 are complementary to each other, when the left semicircular shielding plate 228 shields the front side wave-shaped groove 224, the right semicircular shielding plate 228 shields the rear side wave-shaped groove 224, and vice versa, thus, in the same bidirectional movement process, the rotating nozzles 22 in the rectangular material cavities 21 on the left and right sides produce opposite rotating directions due to the different positions of the matched wave-shaped grooves 224, and the interlaced complement of the spraying trajectories is realized.

[0036] In addition, a closed annular guide groove 229 is formed on the outer circumferential surface of the semicircular baffle plate 228, the annular guide groove 229 is in the shape of a racetrack as a whole, and the two ends thereof are respectively provided with inclined transition sections. An outer side of the annular connecting plate 225 is sleeved with a fixing ring 230 which is fixedly connected with the rectangular material cavity 21, and a guide rod 231 which is in sliding cooperation with the annular guide groove 229 is mounted on the inner annular surface of the fixing ring 230.

[0037] When the rectangular material cavity 21 moves along the length direction of the composting reactor 1, the fixing ring 230 and the guide rod 231 move synchronously in a straight line. The guide rod 231 slides in the straight line section of the annular guide groove 229, and maintains the current shielding state. When moving to the end of the stroke, the guide rod 231 is in contact with the inclined transition section at the end of the annular guide groove 229, and drives the semicircular baffle plate 228 to rotate under the action of the thrust, so that the guide rod 231 is turned into the other straight line track of the annular guide groove 229. In the return stroke, the guide rod 231 triggers the baffle plate to switch in the reverse direction again, thereby completing the switching of the use path of the wave-shaped groove 224, and realizing the reverse control of the swing direction of the rotating nozzle 22 in the forward stroke and the return stroke.

[0038] As shown in Figure 4 and Figure 5 To eliminate the blind area of spraying formed between the rectangular material cavity 21 and the rotating nozzle 22, an inclined plate 232 is arranged in the rectangular region enclosed between the rotating nozzle 22 and the rectangular material cavity 21. A plurality of push plates 233 are uniformly arranged on the inclined plate 232. The push plates 233 are in elastic sliding connection with the inclined plate 232, and can be self-adaptively expanded and contracted according to the boundary profile of the rectangular region. Uniformly distributed air permeation holes are formed on the inclined plate 232 and the push plates 233, which effectively prevent material blockage and promote airflow penetration. The inclined plate 232 can synchronously reciprocate with the rotation of the rotating nozzle 22. In the process of reciprocation, the push plates 233 dynamically push and loosen the compost material in the rectangular region, further improving the local mixing uniformity and aeration effect.

[0039] To make the inclined plate 232 reciprocate with the rotating nozzle 22, a pin shaft 234 is hinged at one end of the inclined plate 232 away from the push plates 233, and the pin shaft 234 is in sliding connection with a sliding groove formed on the annular connecting plate 225. The middle part of the inclined plate 232 is hinged to the fixing ring 230. Since the annular connecting plate 225 reciprocates with the rotating nozzle 22, and the fixing ring 230 is relatively stationary, under the action of relative motion, the pin shaft 234 reciprocates along the sliding groove, drives the inclined plate 232 to reciprocate within a limited angle range around the hinge point of the middle part of the inclined plate 232 and the fixing ring 230, thereby continuously driving the push plates 233 to dynamically push and loosen the material blind area in the rectangular region, effectively improving the local mixing uniformity and aeration effect.

[0040] As shown in Figure 4As shown, in order to pre-mix the material in the compost reactor 1 before the operation of the rectangular distribution cavity 21, improve the uniformity and fermentation efficiency of the subsequent reaction, the circumferentially uniformly distributed radial disturbance plates 235 are hinged on the side of the annular connecting plate 225 away from the rotating nozzle 22, the radial disturbance plates 235 can reciprocate radially along the annular connecting plate 225 with the reciprocating rotation of the annular connecting plate 225, so as to dynamically disturb the material at different levels of the pile, promote the mutual mixing of the material at different depths, improve the initial distribution uniformity, and thus create more homogeneous conditions for the penetration and reaction of the subsequent compressed air and composite microbial agent.

[0041] Specifically, the connecting ring 236 is sleeved on the outside of the fixed rod 223, the connecting ring 236 is fixedly connected with the fixed ring 230 through the support rod, and remains stationary relative to the annular connecting plate 225, the connecting shaft 237 is arranged on the radial disturbance plate 235, the connecting shaft 237 is connected with the radial disturbance plate 235 through a ball hinge, the other end of the connecting shaft 237 is hinged with the connecting rod 238 hinged with the fixed ring 230, when the annular connecting plate 225 reciprocates with the rotating nozzle 22, the motion is transmitted to the connecting shaft 237 through the connecting rod 238, driving it to reciprocate radially, the connecting shaft 237 in turn drives the radial disturbance plate 235 to synchronously swing around the hinge point of the radial disturbance plate 235 and the annular connecting plate 225, realizing stable disturbance of the pile material, effectively improving the pre-mixing effect and action reliability.

[0042] Specifically, in operation, the external injection system 3 sends compressed air and liquid composite microbial agent into the left and right rectangular distribution cavities 21, the driving motor 214 is started to drive the bidirectional screw 213 to rotate, driving the left and right rectangular distribution cavities 21 to move synchronously and reciprocally along the length direction of the compost reactor 1, in the moving process, each injection assembly moves synchronously with the cavity, the rotating nozzle 22 realizes circumferential reciprocating rotation under the cooperation of the annular connecting plate 225, the moving ring plate 226, the cooperation rod 227 and the fixed rod 223, at the same time, the semi-circular shielding plate 228 automatically switches the shielding state under the triggering of the guide rod 231 and the annular guide groove 229, ensuring that the rotating nozzle 22 rotates in opposite phases in the forward and return strokes, so that the injection trajectories are staggered and complementary, eliminating the coverage blind area, the compressed air and the microbial agent penetrate into the pile through the uniformly distributed feeding holes 222 of the rectangular distribution cavities 21 and the rotating nozzle 22 in a multi-angle and dynamic manner, in addition, the radial disturbance plate 235 and the inclined paddle 233 mechanism move synchronously to pre-mix and loosen the surface and cavity peripheral material, realizing efficient turning, uniform inoculation and sufficient oxygen supply of the material, and significantly improving the uniformity and efficiency of the organic fermentation reaction.

[0043] Embodiment two, the present embodiment refers to Figure 10 Figure 12 . ​

[0044] The difference between the present embodiment and embodiment one is that the rotating nozzle 22 here comprises a hairpin tube 239 which can also reciprocate synchronously with the annular connecting plate 225 under the cooperation of the matching rod 227 and the wave-shaped groove 224 of the fixed rod 223, and the four corners of the hairpin tube 239 are provided with side connecting pipes 240 which are connected with the rectangular material cavity 21, and the connections between the side connecting pipes 240 and the rectangular material cavity 21 and the hairpin tube 239 all adopt elastic and stretchable connecting heads to adapt to the relative displacement in the rotating process and ensure reliable sealing, for spraying compressed air and composite microbial agent into the pile body along the inclined direction to expand the coverage, and the hairpin tube 239 is provided with a cross-flow pipe 241 which is connected with the hairpin tube 239 and can uniformly distribute the fluid to the four side connecting pipes 240 to form a multi-directional and balanced spraying path, further improving the uniformity of material disturbance and inoculation.
