Description

Technical Field

[0001] The invention relates to the technical field of organic trace element fertilizer processing, and more specifically, to an organic trace element fertilizer processing device and a use method thereof. Background Art

[0002] With the development of modern agriculture, it has become an urgent need to increase crop yield and quality while reducing the use of chemical fertilizers. Nitrogen-fixing, phosphorus-solubilizing, potassium-solubilizing and root-inducing composite bacterial preparations have attracted widespread attention because they can effectively promote plant growth, improve soil fertility and enhance crop resistance. However, the traditional mixing method usually involves directly mixing the bacterial solutions together after each strain is activated separately. In the existing improved technology, each strain is generally activated separately, and the activated bacterial solutions are then mixed together for high-density culture. The cultured bacterial solution is then centrifuged, and finally, the bacterial precipitate is dehydrated and dried to prepare a dormant microbial dry powder.

[0003] Regardless of the existing improved mixing technology or the traditional mixing method, in the preparation process of nitrogen fixation, phosphorus solubilization, potassium solubilization, and rooting composite bacteria, it is necessary to separate the bacterial precipitate and the supernatant. Therefore, the production of supernatant is an inevitable phenomenon. The supernatant contains not only unused nutrients and metabolites, but also may contain biologically active substances that are beneficial to bacterial growth. Therefore, the reasonable recovery and utilization of the supernatant can not only improve resource utilization, but also optimize the growth environment of the strain.

[0004] However, the existing supernatant recovery work requires multiple centrifugation and washing, and in each washing process, the precipitated bacteria at the bottom may flow out when the supernatant is poured out, affecting the stability of the bottom bacteria, causing damage or inactivation of the bacteria, and further affecting the quality and effect of the composite bacterial preparation. Therefore, the operation is relatively complicated and cumbersome, and it cannot be well combined with the existing organic trace element fertilizer processing equipment for synchronous preparation.

[0026] Through the supernatant separation mechanism configured in each group of centrifugal cylinders, during the separation of precipitated bacteria, the driving action of the servo drive module can be utilized to drive the internal circular ring frame to move up and down along the inner isolation cover cylinder, so that a barrier is formed between the bacterial precipitation and the supernatant. The supernatant can be adsorbed and transferred away under the action of the barrier, so that the supernatant can be recovered without a dumping device, which can effectively avoid the outflow of the precipitated bacteria at the bottom and ensure the stability of the bottom bacteria, thereby significantly improving the quality and effect of the composite bacterial preparation of organic trace element fertilizer.

[0027] Through the internal and external separation design of the centrifugal cylinder and the inner isolation cover cylinder, the driving end is transferred out by utilizing the preset cavity, so that the driving end and the bacterial liquid separation end of the inner isolation cover cylinder do not interfere with each other but interact with each other, and the second multi-pole magnetic ring is used to control the supernatant separation mechanism to adjust the separation position, and the synchronous rotation of the first multi-pole magnetic ring can also realize the stirring of the silk thread stirring module. The silk thread stirring module can provide sufficient stirring force while effectively avoiding damage to the bacteria, and the self-resetting winding of the torsion spring rotating rod can realize the adjustment of the length of the silk thread at the stirring end, thereby further improving the recovery and separation effect of the bottom precipitated bacteria.

[0028] Through the fan plates with leaks on the four sides of the supernatant separation mechanism, under the telescopic control of the electric telescopic rod, the extended support plate can be made to reciprocate up and down to control the opening and closing of the leak end of the fan plate with leaks. Under the action of the circular ring frame to achieve separation, the supernatant at the bottom can be further released by opening the leak, and the infusion catheter configured with the infusion unit can directly inject cleaning liquid into the bottom bacterial end, further improving the washing and centrifugal effects.

For some known technologies, those skilled in the art may also adopt other alternatives to implement them; and the accompanying drawings are only for the purpose of describing the embodiments in more detail, and are not intended to specifically limit the present invention.

[0049] like Figures 1 to 9 As shown, an embodiment of the present invention provides an organic trace element fertilizer processing device, comprising a fermentation tank 1, a main injection conduit 2 and a plurality of electric valve conduits 3 are fixedly installed on the top injection end of the fermentation tank 1; and a centrifugal cylinder 4 is movably installed on the upper surface of each electric valve conduit 3 through a sealing sleeve, an inner isolation cover cylinder 8 is fixedly installed at the inner axial position of the centrifugal cylinder 4, and a supernatant separation mechanism 9 is arranged inside the inner isolation cover cylinder 8;

[0050] The upper side of the centrifugal cylinder 4 is provided with a centrifugal device for driving the centrifugal rotation of the centrifugal cylinder 4 as a whole around the electric valve guide tube 3; and the position between the interior of each centrifugal cylinder 4 and the inner isolation cover cylinder 8 is a cavity, and the cavity is provided with a servo drive module 7 for driving the supernatant separation mechanism 9 inside the inner isolation cover cylinder 8 to move;

[0051] The supernatant separation mechanism 9 includes a circular ring frame 91 and a plurality of fan plates 95 with leaks inside the circular ring frame 91. The fan plates 95 with leaks are provided with cross-corresponding liquid extraction units 910 and liquid infusion units 911.

[0052] The liquid extraction unit 910 includes a liquid extraction conduit 913 placed in the leakage of the leaky fan plate 95, and the liquid extraction end of the liquid extraction conduit 913 is located as a whole on the upper surface of the leaky fan plate 95, and is used to extract the bacterial supernatant separated by the annular frame 91 in real time. The infusion unit 911 includes an infusion conduit 914 placed in the leakage of the leaky fan plate 95, and the infusion end of the infusion conduit 914 is located as a whole on the lower surface of the leaky fan plate 95, and is used to circulate cleaning liquid into the bacteria at the bottom of the annular frame 91.

[0053] In order to solve the problem that each washing of the strain in the existing organic trace element fertilizer processing process may cause the bacteria precipitated at the bottom to flow out, affecting the stability of the bacteria and causing damage or inactivation of the bacteria, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution is mainly composed of a fermentation tank 1, a main injection conduit 2, an electric valve conduit 3, a centrifugal cylinder 4, a servo drive module 7, an inner isolation cover cylinder 8, and a supernatant separation mechanism 9. The fermentation tank 1 is a microbial cultivation equipment in the prior art, which can provide an optimal growth environment for microorganisms by controlling parameters such as temperature, pH value, and dissolved oxygen concentration. The configured main injection conduit 2 is used to inject various materials required for the preparation of organic trace element fertilizers, and the multiple groups of centrifugal cylinders 4 on the outside are used to inject nitrogen fixation, phosphorus solubilization, potassium solubilization, and rooting composite bacteria preparations into the tank body for centralized mixing and preparation. The configured electric valve conduit 3 is a valve tube that can automatically control the switch in the prior art, and its upper side is movable through a sealing sleeve of corresponding size. Assemble the centrifuge cylinder 4, and the centrifuge cylinder 4 is connected to the container for storing bacterial preparations in the prior art and the clamping centrifuge device configured externally. Under the driving action of the centrifuge device, the clamping centrifuge device is an industrial clamping centrifuge device in the prior art, including a fixed base and a rotatable clamping device. The clamping device can firmly fix the sample container to be centrifuged. When the drive system is started, the clamping end rotates at high speed to generate centrifugal force to separate the solid particles and liquid in the sample, and can be centrifugally rotated around the sealing sleeve of the electric valve guide tube 3. The centrifuge cylinder 4 and the inner isolation cover tube 8 are a hollow sleeve structure with inner and outer coaxial centers. The servo drive module 7 is configured in the cavity interlayer to control the supernatant separation mechanism 9 inside the inner isolation cover tube 8 to separate the supernatant, so as to solve the problem that each washing of the strain in the existing organic trace element fertilizer processing process may drive the bacteria precipitated at the bottom to flow out, affecting the stability of the bacteria, causing damage or inactivation of the bacteria;

[0054] Correspondingly, the configured supernatant separation mechanism 9 is mainly composed of a circular ring frame 91, a fan plate with a leak 95, a pumping unit 910 and an infusion unit 911. The pumping unit 910 is used to pump out the separated supernatant in real time, while the infusion unit 911 is used to inject cleaning liquid for multiple cleanings to repeatedly wash out the supernatant in the precipitated bacteria. All components are concentrated on the input end of the fermentation tank 1 to simplify the entire operation process.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the servo drive module 7 includes a first servo motor 71 fixedly mounted at the side position of the bottom of the centrifugal cylinder 4, and the output end of the first servo motor 71 penetrates into the interior of the centrifugal cylinder 4; and a gear sleeve 72 is fixedly mounted on the penetration end, and a gear ring 73 is movably mounted at the inner bottom axial position of the centrifugal cylinder 4, and the outer ring edge of the gear ring 73 is provided with a tooth opening corresponding to the gear sleeve 72 meshing, and the inner ring edge of the gear ring 73 is fixedly mounted with a first multi-pole magnetic ring 74, and the inner ring wall of the first multi-pole magnetic ring 74 is in contact with the outer surface of the inner isolation cover cylinder 8.

[0056] The inner isolation cover tube 8 is an aluminum cylinder in the prior art to avoid interference with the adsorption effect of the inner and outer magnetic rings.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a second servo motor 75 is fixedly connected to the side edge of the upper surface of the first multi-pole magnetic ring 74, a threaded rod 76 is fixedly connected to the output end of the second servo motor 75, a limiting rod 77 is fixedly connected to the other side edge of the upper surface of the first multi-pole magnetic ring 74 flush with the threaded rod 76, a nut ring 78 corresponding to the threaded rod 76 is slidably mounted on the limiting rod 77, a second multi-pole magnetic ring 79 is fixedly mounted on the inner side of the nut ring 78, and the inner wall of the circular ring of the second multi-pole magnetic ring 79 is fitted to the outer surface of the inner isolation cover tube 8.

[0058] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, a third multi-pole magnetic ring 92 is fixedly connected to the outer circular ring edge of the circular ring frame 91, and the magnetic poles of the third multi-pole magnetic ring 92 correspond to the magnetic poles of the second multi-pole magnetic ring 79 by adsorption. The upper and lower edge positions of the third multi-pole magnetic ring 92 are fixedly connected with sealing rings attached to the inner wall of the inner isolation cover tube 8. A wire stirring module 93 is arranged at the bottom of the circular ring frame 91. The wire stirring module 93 includes a separation cavity skeleton 931. The separation cavity skeleton 931 is X-shaped as a whole to separate the inner ring of the circular ring frame 91 into four fan-shaped openings; and a fan plate 95 with a leakage is fixedly connected to each fan-shaped opening, and the bottom surface of the fan plate 95 with a leakage is flush with the bottom surface of the circular ring frame 91.

[0059] Among them, the working process of the configured servo drive module 7 is:

[0060] The first step is to activate nitrogen-fixing bacteria, phosphate-dissolving bacteria, potassium-dissolving bacteria, and root-forming bacteria in their respective growth activation medium, such as peptone medium, glucose medium, etc., and then inoculate the preserved strains into the activation medium, usually using a slant medium or a liquid medium, monitor their growth curves for regular sampling, measure the OD value of the bacterial solution, draw a growth curve, ensure that the strains reach the high-density culture target, and finally inject the finished strains and the culture reagents into the centrifugal tube 4 for centrifugal separation and strain washing;

[0061] In the second step, under the centrifugal effect of the centrifugal cylinder 4, after it is stabilized, the bacteria in each centrifugal cylinder 4 are precipitated at the bottom of the centrifugal end, and the precipitate and the supernatant are separated. The threaded rod 76 at the output end of the second servo motor 75 rotates clockwise to control the nut collar 78 engaged on its surface to move downward along the limit rod 77;

[0062] In the second step, during the downward movement of the nut ring 78, the interior of the isolation cover tube 8 thereof will also move downward through the circular ring frame 91 attracted by the second multi-pole magnetic ring 79, and the circular ring frame 91 will gently squeeze the strain sediment at the bottom, so that the strain sediment at the bottom is spread as flat as possible, and simultaneously create a separation barrier located on the upper surface of the strain sediment.

[0063] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the supernatant separation mechanism 9 also includes an electric telescopic rod 97 fixedly installed at the axial position of the upper surface of the separation cavity skeleton 931, and a lifting cylindrical sleeve 98 is fixedly connected to the telescopic end of the electric telescopic rod 97. The outer side of the lifting cylindrical sleeve 98 is fixedly installed with an extension support plate 99 corresponding to the upper and lower fan plate 95 with a leak. The pumping unit 910 and the infusion unit 911 are fixedly installed on the upper surface of the extension support plate 99 in a cross-arranged order. The pumping unit 910 includes a pumping pump and a pumping catheter 913 on the extraction end of the pump corresponding to the leak of the fan plate 95 with a leak, and the pumping port of the pumping catheter 913 is located on the side of the pumping catheter 913. The infusion unit 911 includes an infusion pump and an infusion catheter 914 on the delivery end of the infusion pump corresponding to the leak of the fan plate 95 with a leak, and the infusion port of the infusion catheter 914 is located at the bottom of the infusion catheter 914.

[0064] Among them, the configured extraction unit 910 and infusion unit 911 are both automatically controlled extraction and infusion equipment in the prior art, including corresponding extraction pumps and infusion pumps. Through the operation of the extraction pumps and infusion pumps, the extraction catheter 913 and infusion catheter 914 on their output ends can be controlled to perform extraction and infusion respectively.

[0065] The workflow of the provided supernatant separation mechanism 9 is:

[0066] First, after the servo drive module 7 completes the separation work of the separation barrier, its liquid extraction conduit 913 and the liquid infusion conduit 914 are sealed and inserted on the corresponding fan plate 95 with a leak. In this state, the liquid extraction unit 910 is opened, and the liquid extraction port of the liquid extraction conduit 913 of the liquid extraction unit 910 is set on the side of the liquid extraction conduit 913. When the liquid extraction port is sealed and inserted on the corresponding fan plate 95 with a leak, the liquid extraction port is located at the bottom of the fan plate 95 with a leak. In this position, the liquid extraction unit 910 is started, and its liquid extraction conduit 913 can extract the liquid on the upper side of the separation end of the annular frame 91, that is, the separated strain precipitation supernatant;

[0067] Then, after the supernatant of the strain precipitation is transferred by the extraction catheter 913, the infusion unit 911 is opened again. Since the infusion port of the infusion catheter 914 at the output end of the infusion unit 911 is located at the bottom of the infusion catheter 914, after the seal is inserted into the fan plate with leakage 95, the infusion end of the infusion catheter 914 can directly act on the strain precipitation at the bottom. At this time, the cleaning liquid is transported to the strain precipitation through the infusion unit 911, which can directly act on the inside of the strain precipitation. When the injected cleaning liquid reaches a certain volume, the second servo motor 75 of the servo drive module 7 can drive the threaded rod 76 counterclockwise to control the circular ring frame 91 at the adsorption end to move upward, and reserve the corresponding space:

[0068] Finally, after the injected cleaning liquid reaches a certain volume, it is centrifuged and cleaned, and the strain precipitate and supernatant are separated again, and the transfer of the supernatant is repeated. This is repeated two to three times to ensure that the impurities and residual culture medium on the surface of the bacteria are completely removed, and the washed bacterial precipitate is discharged through the electric valve conduit 3 for high-speed centrifugation to remove excess water, and then filtered, dehydrated and freeze-dried to prepare the corresponding bacterial microbial dry powder, which is convenient for the subsequent mixing and processing of organic trace element fertilizers.

[0069] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 As shown, the wire stirring module 93 also includes a torsion spring rotating rod 932 fixedly installed in the cavity of each partitioning cavity skeleton 931, and a plurality of winding frames 933 are fixedly installed in sequence on the surface of the torsion spring rotating rod 932, and the winding frames 933 are all wound with wires 934. The bottom of the partitioning cavity skeleton 931 is provided with reserved wire outlets 935 corresponding to the winding frames 933 above and below for the wires 934 to pass through; and a pointed sleeve 936 for scraping the wires 934 is fixedly installed on the outer side of each reserved wire outlet 935.

[0070] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the wire stirring module 93 also includes a base disc 10 movably mounted on the bottom of the inner isolation cover tube 8, and a fourth multi-pole magnetic ring 11 is fixedly connected to the outer edge surface of the base disc 10, and the magnetic poles of the fourth multi-pole magnetic ring 11 are adsorbed and correspond to the magnetic poles of the first multi-pole magnetic ring 74, and the protruding ends of the wire 934 wound on the winding frame 933 are fixedly connected to the upper surface of the base disc 10, and an opening communicating with the electric valve conduit 3 is opened at the axial position of the base disc 10.

[0071] Among them, the configured torsion spring rotating rod 932 is a rod provided with a torsion spring in the prior art. Under the torsion force of the torsion spring, it has a torsion force opposite to the pulling direction of the silk thread 934, driving the winding frame 933 to retract the silk thread 934 in real time. The configured silk thread 934 is a high-strength fine silk thread in the prior art, which has biocompatibility, such as nylon thread. In the working process of the servo drive module 7 cooperating with the supernatant separation mechanism 9 to separate the supernatant, each time the cleaning liquid is injected, it is necessary to cooperate with the stirring member for stirring to assist the reagents to blend. In order to ensure that the stirring end does not damage the bacteria, a relatively flexible stirring method is selected, and the specific process is as follows:

[0072] First, when stirring is required, the gear sleeve 72 at the output end of the first servo motor 71 drives the outer meshing gear ring 73 to rotate. When the gear ring 73 rotates, the first multi-pole magnetic ring 74 and the second multi-pole magnetic ring 79 will also rotate synchronously, and the third multi-pole magnetic ring 92 and the fourth multi-pole magnetic ring 11 corresponding to the adsorption will also rotate. When the third multi-pole magnetic ring 92 and the fourth multi-pole magnetic ring 11 rotate synchronously, the configured wire 934 will rotate inside the inner isolation cover tube 8 to perform stirring.

[0073] Furthermore, as the interior of the inner isolation cover tube 8 is gradually lifted as the cleaning liquid is injected, in order to ensure the adaptability of the stirring end, a winding frame 933 on a torsion spring rotating rod 932 can be wound with a sufficiently long silk thread 934. In the process of the circular frame 91 being lifted upward, the silk thread 934 can also be adaptively stretched, and a pointed sleeve 936 for clamping the silk thread 934 is arranged at the position of the reserved wire outlet 935. During each pulling process, it can be scraped to clean the outer surface of the silk thread 934. The infrared ranging unit 94 arranged at the bottom of the axis of the separating cavity skeleton 931 is an infrared ranging device of the prior art, which can provide real-time feedback of the distance to the bottom bacterial body through infrared ranging, so as to better control the adjustment position of the circular frame 91.

[0074] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, a connecting hose 912 is connected between the two opposite liquid extraction units 910 and the two infusion units 911 on the extended support plate 99, and three groups of auxiliary branch pipes 5 are fixedly installed on the top of the inner isolation cover tube 8, one group of auxiliary branch pipes 5 is connected to the connecting hose 912 between the two liquid extraction units 910; one group of auxiliary branch pipes 5 is connected to the connecting hose 912 between the two infusion units 911; one group of auxiliary branch pipes 5 is used to inject bacterial liquid to be centrifuged and washed into the inner isolation cover tube 8.

[0075] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, a visible cover 6 is disposed on the surface of the centrifugal cylinder 4 and the inner isolation cover cylinder 8, an infrared ranging unit 94 is fixedly installed at the axial bottom position of the separating cavity skeleton 931, and the infrared emitting end of the infrared ranging unit 94 faces the bottom of the inner isolation cover cylinder 8, and a sealing ring 96 is fixedly installed in each leakage of the leakage fan plate 95.

[0076] Among them, the connecting hose 912 arranged between the extraction unit 910 and the infusion unit 911 is to make the units on both sides communicate with each other for centralized control, and is connected to the corresponding auxiliary branch pipe 5, which can be discharged outward and injected inward in a centralized manner. The sealing ring 96 fixedly installed in each leakage port is to ensure that when the extraction catheter 913 and the infusion catheter 914 are inserted into the leakage port with the leakage fan plate 95, the leakage port end is relatively sealed.

[0077] The method of use provided by the present invention is as follows:

[0078] S1: First, the cultured bacterial liquid is injected into the centrifuge cylinder 4 through the auxiliary branch pipe 5, and the centrifuge cylinder 4 is connected to the externally configured clamping centrifuge device, and the centrifuge device is driven to perform centrifugal rotation to precipitate the bacterial cells at the bottom of the centrifuge cylinder 4;

[0079] S2: Then, the servo drive module 7 controls the second servo motor 75 to rotate, driving the threaded rod 76 and the nut ring 78 to move downward, so that the annular frame 91 moves downward to form a separation barrier to separate the bacterial sediment from the supernatant;

[0080] S3: Then, the liquid extraction unit 910 is opened to extract the supernatant through the liquid extraction conduit 913, and then the liquid infusion unit 911 is opened to inject the cleaning liquid into the bacterial sediment through the liquid infusion conduit 914, and the annular frame 91 is driven to move upward to reserve space for centrifugal cleaning;

[0081] S4: Finally, repeat steps S2 and S3 2 to 3 times to ensure that the impurities and residual culture medium on the surface of the bacteria are completely removed, and then discharge the washed bacterial precipitate through the electric valve conduit 3, filter and dehydrate it, and freeze-dry it to prepare microbial dry powder of dormant nitrogen-fixing, phosphorus-solubilizing, potassium-solubilizing, and rooting composite bacteria preparations. The dry powders are mixed in a certain proportion to prepare organic trace element fertilizers.

[0082] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0083] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
