Description

Technical Field

[0001] The invention relates to the technical field of fermentation, and in particular to a low-cost microbial organic fertilizer fermentation device. Background Art

[0002] Microbial organic fertilizer is popular among growers because of its low cost. If the organic fertilizer composting and fermentation technology is processed according to the ordinary composting and fermentation method, it will not only take a long time, but also fail to achieve 100% full maturity. The organic fertilizer composting and fermentation technology is to use compost rapid decomposition agents to compost and ferment organic fertilizer raw materials. It can also be used with the help of composting and fermentation equipment, that is, fermentation tanks, which can ferment faster and take less time.

[0003] Aeration is required during the fermentation process of microbial organic fertilizer to increase the oxygen content in the tank and ensure the rate of microbial fermentation. However, traditional fermentation tanks generally have a horizontal stirring structure. The fertilizer accumulation cannot ensure that the oxidation reaction efficiency of the upper and lower layers of fertilizer is the same, which can easily cause uneven fermentation of the upper and lower layers of fertilizer. Summary of the invention

[0008] In at least some embodiments, two limiting strips are integrally formed at one end of the fermentation tank, and two limiting grooves are provided on the externally threaded tube, which are slidably engaged with the limiting strips and are used for rotational limiting of the externally threaded tube.

[0009] In at least some embodiments, the fermentation auxiliary component includes an aeration head and a stainless steel belt. The aeration head is fixedly connected to one end of an external threaded pipe. Both ends of the aeration head are conical and are provided with multiple aeration ports with filters. An outer ring is fixedly welded to the outer end of the stainless steel belt, and a movable ring is fixedly welded inside the outer ring. A spring is fixedly installed at one end of the movable ring, and a fixed ring is fixedly installed at one end of the spring. The fixed ring is rotatably mounted on the outside of the aeration head.

[0010] In at least some embodiments, two driving grooves are provided in the fermentation tank, both of which are spiral and interconnected, and the two driving grooves are symmetrically arranged about the center line of the fermentation tank and have opposite spiral directions.

[0015] 2. The specially designed stainless steel belt in the fermentation auxiliary component is linked to the rotation and extension of the second drive component. The rotation of the spiral frustum-shaped stainless steel belt has the effect of stirring and breaking up the fertilizer. The aeration component is used for aeration to make the oxidation reaction between the fertilizer and the air more efficient. At the same time, the extension direction of the stainless steel belt is opposite to the falling direction of the fertilizer, forming convection, further improving the breaking effect of the fertilizer, thereby improving the overall aeration and fermentation effect of the microbial organic fertilizer.

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] according to Figure 1 — Fig.12 ,like Figure 1 In the embodiment of the present invention, a low-cost microbial organic fertilizer fermentation device includes a fermentation table 1 and a fermentation tank 2. A control host 101 is fixedly installed on the back of the fermentation table 1, an arc-shaped rack 103 is fixedly installed on the front end of the fermentation table 1, and a tank mouth 203 is integrally formed at one end of the fermentation tank 2. The device also includes: A first driving assembly 3 installed on the fermentation table 1 for driving the fermentation tank 2 to shake; A second driving assembly 4 for cooperating with the first driving assembly 3 to drive the fermentation tank 2 to rotate; A fermentation auxiliary component 5 disposed inside the fermentation tank 2 for enhancing the reaction effect between fertilizer and oxygen; An aeration assembly 6 is installed on the fermentation table 1 and is used to aerate the fermentation tank 2 .

[0021] like Figure 1 , Figure 2 and Figure 5In the embodiment, the first driving assembly 3 includes a rotating frame 301 and a first driven pulley 302, the rotating frame 301 is rotatably installed at the front end of the fermentation platform 1, a retaining ring 303 for installing the fermentation tank 2 is fixedly installed inside the rotating frame 301, a sliding ring 201 is fixedly installed outside the fermentation tank 2, a sliding groove 304 that is slidably adapted to the sliding ring 201 is opened in the retaining ring 303, a first transmission shaft 305 is fixedly installed on the back of the rotating frame 301, a driving frame 306 is fixedly installed on the first transmission shaft 305, the first driven pulley 302 is rotatably installed at the rear end of the fermentation platform 1, a first driving pulley 102 is rotatably installed on the back of the fermentation platform 1, a motor for driving the first driving pulley 102 is fixedly installed on the back of the fermentation platform 1, a transmission belt is sleeved between the first driven pulley 302 and the first driving pulley 102, and the first driven pulley 3 02's shaft is fixedly mounted with a connecting rod 307, and a sliding rod 308 is slidably inserted at one end of the connecting rod 307 away from the first driven pulley 302, and the sliding rod 308 is slidably mounted on the driving frame 306, wherein the motor drives the first active pulley 102 to rotate, and the first active pulley 102 drives the first driven pulley 302 to rotate through the transmission belt, and the first driven pulley 302 drives the connecting rod 307 to rotate about the axis of the first driven pulley 302, and during the rotation of the connecting rod 307, the sliding rod 308 is driven to slide back and forth on the driving frame 306, and during the sliding process, the driving frame 306 is driven to reciprocate up and down (the sliding rod 308 reciprocates and extends at one end of the connecting rod 307), thereby driving the fermentation tank 2 to shake through the rotating frame 301, so that the fertilizer is turned back and forth in the fermentation tank 2 during the fermentation process, so that the fermentation degree of the upper and lower layers of fertilizer is more uniform.

[0022] like Figure 6 , Figure 7 and Fig. 9In the embodiment, the second driving assembly 4 includes a second transmission shaft 401, a third transmission shaft 402, an externally threaded tube 403 and a second driven pulley 404. The second transmission shaft 401 is rotatably mounted on the rotating frame 301. An internally threaded tube 405 is rotatably inserted in the tank mouth 203 of the fermentation tank 2. One end of the second transmission shaft 401 is rotatably sleeved on the internally threaded tube 405. A right-angle sleeve 406 is rotatably sleeved between the second transmission shaft 401 and the third transmission shaft 402. A second driving pulley 407 is fixedly sleeved on the second transmission shaft 401. A second driven pulley 404 is fixedly sleeved on the tank mouth 203 of the fermentation tank 2. A transmission belt is sleeved between the second driven pulley 404 and the second driving pulley 407. A first bevel gear 408 meshingly connected to the arc rack 103 is fixedly sleeved on the second transmission shaft 401. A second bevel gear 409 is fixedly mounted on the transmission shaft 402, and two third bevel gears 410 meshingly connected to the second bevel gear 409 are fixedly mounted on the internal threaded tube 405. The two third bevel gears 410 are arranged in a mirror image. In the process of the first driving component 3 driving the rotating frame 301 to rotate back and forth, the second transmission shaft 401 will be driven to swing back and forth with the axis of the rotating frame 301, and the center of the arc rack 103 is coaxial with the axis of the rotating frame 301. Therefore, the meshing action of the first bevel gear 408 and the arc rack 103 will drive the second transmission shaft 401 to rotate. The rotation of the second transmission shaft 401 drives the tank mouth 203 to rotate through the transmission action of the second active pulley 407 and the second driven pulley 404, that is, drives the fermentation tank 2 to rotate, and cooperates with the shaking action of the fermentation tank 2 to make the material layer turning effect better.

[0023] like Figure 8 and Fig. 9 In the fermentation tank 2, two limiting strips 204 are integrally formed at one end thereof, and two limiting grooves slidably engaged with the limiting strips 204 are provided on the externally threaded tube 403 for rotation and limiting of the externally threaded tube 403. The fermentation tank 2 rotates to drive the third bevel gear 410 on the tank opening 203 to rotate, and the third bevel gear 410 on the tank opening 203 rotates to drive another third bevel gear 410 to rotate through the rotation action with the second bevel gear 409, that is, to drive the internally threaded tube 405 to rotate, and the rotation of the internally threaded tube 405 drives the externally threaded tube 403 to reciprocate and extend (such as Figure 8 In the embodiment, the sliding engagement of the limiting strip 204 and the limiting groove prevents the external threaded tube 403 from rotating).

[0024] like Fig.10In the figure, the fermentation auxiliary component 5 includes an aeration head 501 and a stainless steel belt 502. The aeration head 501 is fixedly connected to one end of the external threaded tube 403. Both ends of the aeration head 501 are conical and are provided with a plurality of aeration ports 503 with filters. An outer ring 504 is fixedly welded to the outer end of the stainless steel belt 502. A movable ring 506 is fixedly welded inside the outer ring 504. A spring 507 is fixedly installed at one end of the movable ring 506. A fixed ring 508 is fixedly installed at one end of the spring 507. The fixed ring 508 is rotatably sleeved on the outer side of the aeration head 501. Two sections of driving grooves 202 are provided in the fermentation tank 2. The two sections of driving grooves 202 are both spiral and connected to each other. The two sections of driving grooves 202 are symmetrically arranged about the center line of the fermentation tank 2 and have opposite spiral directions. A convex column 505 that slides with the driving groove 202 is provided on the outer ring 504. The external threaded tube 403 is telescopic to drive the aeration head 501 and the steel belt to telescopically move. The telescopic direction is as follows: Figure 6 From the perspective of perspective, when the fermentation tank 2 tilts to the left, the external threaded tube 403 drives the stainless steel belt 502 to move to the right. In the process of the fermentation tank 2 recovering from the state of tilting to the left to the horizontal state, the external threaded tube 403 drives the stainless steel belt 502 to move to the left. In the process of the fermentation tank 2 tilting to the right from the horizontal state, the stainless steel belt 502 continues to move to the left. It can be seen from the above that the aeration head 501 and the stainless steel belt 502 are always opposite to the falling direction of the fertilizer in the fermentation tank 2. Therefore, the stainless steel will form convection lifting with the fertilizer, and the fertilizer will be dispersed. At the same time, in the process of the movement of the stainless steel belt 502, the driving action of the convex column 505 on the outer ring 504 and the driving groove 202 will drive the stainless steel belt 502 to rotate and stir the fertilizer.

[0025] like Fig.11 In the embodiment, the stainless steel belt 502 is in a vortex shape, and a plurality of sawtooth plates 509 for breaking up the fertilizer are fixedly welded on the stainless steel belt 502. The radius of the movable circle 506 is greater than the radius of the fixed circle 508. The spring 507 is a vortex spring, and the width of the spring 507 is the radius difference between the movable circle 506 and the fixed circle 508. The vortex-shaped stainless steel belt 502 is used for its toughness, and the stainless steel belt 502 is in a frustum shape (toward the direction of the fertilizer falling) under the action of the gravity of the fertilizer, and the material at the non-conical end enters the stainless steel belt. In the belt 502, because the stainless steel belt 502 body is also curved, the fertilizer is thrown outwards under the centrifugal action, and is dispersed by the tooth plate during the throwing process to enhance the three-dimensional breaking effect of the fertilizer. In addition, because the two ends of the aeration head 501 are also tapered, the fertilizer reacts with the oxygen in the air ejected from the aeration port 503 during the dispersion and throwing process to enhance the oxidation reaction effect. When the stainless steel belt 502 moves in another direction, it returns to its original position due to the elastic action of the vortex spring, thereby performing a reciprocating dispersion and aeration treatment on the fertilizer.

[0026] like Fig.12In the embodiment, the aeration assembly 6 includes two air cylinders 601 and a three-way pipe 602. The two air cylinders 601 are rotatably installed on both sides of the rotating frame 301 respectively. The air cylinders 601 are rotatably connected to the fermentation table 1 at one end away from the rotating frame 301. The three-way pipe 602 is fixedly installed on the fermentation table 1. The valve cores of the two air cylinders 601 are connected to two air inlets of the three-way pipe 602. The air outlet of the three-way pipe 602 is fixedly connected to the end of the external threaded pipe 403 away from the aeration head 501. In the process of the first driving assembly 3 driving the rotating frame 301 to drive the fermentation tank 2 to shake, the two air cylinders 601 are also driven to continuously pump air, and the air is transported to the external threaded pipe 403 through the three-way pipe 602, and finally sprayed out through the aeration head 501, so as to achieve the purpose of automatic aeration, and as Figure 1 In the fermentation tank 2, the fermentation tank 2 is equipped with a pressure relief device and a pressure sensing device, which can relieve the pressure when the air pressure in the fermentation tank 2 is too high, and the oxygen in the air reacts with the fertilizer. The pressure relief is only to discharge the other gases in the air. This is a well-known technology and will not be elaborated here.

[0027] The specific working principle is to load and unload materials through the feed inlet and discharge port of the fermentation tank 2 (such as Figure 1 ), after the loading is completed, the motor drives the first active pulley 102 to rotate, and the first active pulley 102 drives the first driven pulley 302 to rotate through the transmission belt, and the first driven pulley 302 drives the connecting rod 307 to rotate about the axis of the first driven pulley 302, and the connecting rod 307 drives the sliding rod 308 to slide back and forth on the driving frame 306 during the rotation process, and the driving frame 306 is driven to reciprocate up and down during the sliding process (the sliding rod 308 reciprocates and retracts at one end of the connecting rod 307), thereby driving the fermentation tank 2 to shake through the rotating frame 301, so that the fertilizer is turned back and forth in the fermentation tank 2 during the fermentation process, so that the fermentation degree of the upper and lower layers of fertilizer is more uniform; When the first driving assembly 3 drives the rotating frame 301 to rotate back and forth, the second transmission shaft 401 will be driven to swing back and forth with the axis of the rotating frame 301, and the center of the arc-shaped rack 103 is coaxial with the axis of the rotating frame 301. Therefore, the second transmission shaft 401 will be driven to rotate through the meshing action of the first bevel gear 408 and the arc-shaped rack 103. The rotation of the second transmission shaft 401 drives the tank mouth 203 to rotate through the transmission action of the second driving pulley 407 and the second driven pulley 404, that is, drives the fermentation tank 2 to rotate, and cooperates with the shaking action of the fermentation tank 2 to achieve a better material layer turning effect; The rotation of the fermentation tank 2 drives the third bevel gear 410 on the tank mouth 203 to rotate. The rotation of the third bevel gear 410 on the tank mouth 203 drives another third bevel gear 410 to rotate through the rotation action with the second bevel gear 409, that is, drives the internal threaded tube 405 to rotate. The rotation of the internal threaded tube 405 drives the external threaded tube 403 to reciprocate and extend by utilizing the threaded connection with the external threaded tube 403, so as to drive the fermentation auxiliary component 5 to assist the fertilizer fermentation. The specific process is as follows: the extension and contraction of the external threaded tube 403 drives the aeration head 501 and the steel belt to extend and contract. The extension and contraction direction is as follows: Figure 6 From the perspective of the perspective, when the fermentation tank 2 tilts to the left, the external threaded tube 403 drives the stainless steel belt 502 to move to the right. In the process of the fermentation tank 2 returning to the horizontal state from the state of tilting to the left, the external threaded tube 403 drives the stainless steel belt 502 to move to the left. In the process of the fermentation tank 2 tilting to the right from the horizontal state, the stainless steel belt 502 continues to move to the left. It can be seen from the above that the aeration head 501 and the stainless steel belt 502 are always opposite to the falling direction of the fertilizer in the fermentation tank 2. Therefore, the stainless steel will form convection lifting with the fertilizer, and the fertilizer will be dispersed. At the same time, in the process of the movement of the stainless steel belt 502, the convex column 505 on the outer ring 504 and the driving action of the driving groove 202 will drive the stainless steel belt 502 to rotate and stir the fertilizer. By utilizing the toughness of the vortex-shaped stainless steel belt 502 and the gravity of the fertilizer, the stainless steel belt 502 will be in a cone shape (toward the direction of fertilizer falling), and the materials at the non-conical end will enter the stainless steel belt 502. Since the stainless steel belt 502 body also presents a curvature, the fertilizer is thrown outwards under the centrifugal action, and is dispersed by the tooth plate during the throwing process to enhance the three-dimensional breaking effect of the fertilizer. In addition, since the two ends of the aeration head 501 are also tapered, the fertilizer reacts with the oxygen in the air ejected from the aeration port 503 during the dispersion and throwing process, thereby enhancing the oxidation reaction effect. When the stainless steel belt 502 moves in another direction, it will return to its original position by utilizing the elasticity of the vortex spring, thereby performing a reciprocating dispersion and aeration treatment on the fertilizer. During the fermentation process, while the first driving component 3 drives the rotating frame 301 to drive the fermentation tank 2 to shake, it will also drive the two air cylinders 601 to continuously inflate, and transport the air to the external threaded pipe 403 through the three-way pipe 602, and finally spray it out through the aeration head 501 to achieve the purpose of automatic aeration. After the fermentation is completed, the material can be discharged through the discharge port.
