Description

Technical Field

[0001] The invention relates to the technical field of organic liquid fertilizer treatment, in particular to a fermentation device for treating organic liquid fertilizer. Background Art

[0002] Organic fertilizers generally fall into two categories: fixed organic fertilizers and liquid organic fertilizers. They can reduce the use of chemical fertilizers and pesticides on edible plants, thereby reducing their impact on the environment and human health. Liquid organic fertilizers are highly concentrated, highly efficient, multifunctional, and offer comprehensive nutritional benefits. Compared to traditional chemical fertilizers, they are quickly absorbed by plants, preventing loss. They are also simple to apply, transport, and store.

[0003] In the related art, the existing grassland areas will adapt to local conditions when producing organic fertilizers. Therefore, sheep manure or animal manure will be collected and finally concentrated in the interior of a fermentation tank. The manure will be fermented by various means such as adding liquid and sealing, and temperature control and oxygenation. The fermented liquid can be used as organic liquid fertilizer. In the existing art, the manure in the grassland will carry some grass or wool and other debris during the collection and fermentation process, which will easily affect the quality of the final organic liquid fertilizer in the subsequent fermentation process. Secondly, the traditional spiral auger feeding is prone to jamming if the gap between the spiral edge and the inner wall of the feeding barrel is large. If the gap is small, production will be difficult and the friction resistance will be large, which will easily affect the transportation and feeding of manure.

[0004] Therefore, it is necessary to provide a fermentation equipment for organic liquid fertilizer processing to solve the above technical problems. Summary of the Invention

[0021] Compared with related technologies, the motor structure provided by the present invention has the following beneficial effects:

[0022] The driving motor controls the driving gear to rotate clockwise. When the driving gear rotates clockwise, it engages and drives the driven gear to rotate counterclockwise. At this time, the counterclockwise rotating driven gear controls the screw to rotate inside the feeding barrel. The rotation of the screw can transfer the feces falling from above through the feeding barrel to the inside of the fermentation tank for storage and fermentation.

[0023] When the driving motor drives the screw to rotate and feed the material, the driving pulley on the output shaft of the driving motor will also rotate clockwise, transmitting the power through the belt to control the rotation of the driven pulley. When the driven pulley rotates, it can drive the fan to rotate inside the frame to generate wind force. In this way, when the falling feces passes through the wind force generated by the fan, the wool, grass and other small-density debris will be blown away from the feces by the fan. Therefore, the debris will fall into the debris removal frame and fall into the collection box. The feces must have a high density, so it is not affected by the wind force and falls directly from the unloading frame to the loading barrel below for transmission.

[0024] The driving motor drives the rotation of the screw to stably complete the rotational transmission of the feces dropped from the discharge frame inside the feeding barrel, and during the feeding process, it can also drive the fan to rotate to generate wind force, so as to remove grass, wool and other hair in the feces, thereby ensuring the higher quality of the final fermented product. Secondly, compared with the traditional installation method of pipes and screws, the contact area between the screw and the feeding barrel in this case is small, which not only facilitates the preparation of the screw and the feeding barrel, but also the first scraper and the second scraper on the inclined surfaces on both sides can also solve the feces adhering to the inner wall of the feeding barrel, thereby solving the gap problem of the screw.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] First embodiment:

[0055] The invention provides a fermentation device for treating organic liquid fertilizer.

[0056] Please combine Figures 1 to 9 , a fermentation device for treating organic liquid fertilizer, comprising a fermentation tank 1, a feeding mechanism 3 and an impurity removal mechanism 4;

[0057] The outer wall of the fermentation tank 1 is fixedly provided with a mounting frame 2, and the feeding mechanism 3 is located inside the mounting frame 2;

[0058] The feeding mechanism 3 includes a driving motor 32 mounted on the inner wall of the mounting frame 2, and a driving gear 33 is connected to the output shaft keyway of the driving motor 32. A loading barrel 31 is fixed to the outer wall of the fermentation tank 1 and located inside the mounting frame 2. A screw 35 is rotatably connected to the inner axis of the loading barrel 31, and a driven gear 34 is connected to the outer axis of the screw 35 through a keyway.

[0059] Combine Figure 3 : First, start the drive motor 32 to control the drive gear 33 to rotate clockwise. When the drive gear 33 rotates clockwise, it engages and drives the driven gear 34 to rotate counterclockwise. At this time, the counterclockwise rotating driven gear 34 controls the screw 35 to rotate inside the upper barrel 31. Through the rotation of the screw 35, the feces falling from above can be transferred through the upper barrel 31 to the inside of the fermentation tank 1 for storage and fermentation.

[0060] The driving gear 33 and the driven gear 34 are meshed with each other, and the angle between the extended axis of the driving gear 33 and the extended axis of the driven gear 34 is 90 degrees.

[0061] The impurity removal mechanism 4 includes a collecting box 43, a blanking frame 41 is fixedly provided on the upper surface of the upper barrel 31, a dust removal frame 42 is fixedly provided on the side wall of the blanking frame 41, two clamping plates 44 are fixedly provided on the upper surface of the collecting box 43, a frame 46 is embedded in the inner wall of the blanking frame 41 and located in the same horizontal direction as the dust removal frame 42, a fan 47 is rotatably installed inside the frame 46, a driven pulley 49 is connected to the back of the frame 46 and a keyway is located at the axis of the fan 47, a driving pulley 45 is connected to the outer wall keyway of the output shaft of the driving motor 32, a belt 48 is provided on the outer wall of the driving pulley 45 and the driven pulley 49, and a hopper 9 is fixedly provided on the top of the blanking frame 41;

[0062] Combine Figure 7 and Figure 9 : Before fermentation, the collected feces need to be put down from the hopper 9. When the driving motor 32 drives the screw 35 to rotate and feed the material, the driving pulley 45 on the output shaft of the driving motor 32 will also rotate clockwise and transmit the transmission through the belt 48 to control the rotation of the driven pulley 49. When the driven pulley 49 rotates, it can drive the fan 47 to rotate inside the frame 46 to generate wind force. In this way, when the falling feces passes through the wind force generated by the fan 47, the wool or grass with low density will be blown away from the feces by the fan 47. Therefore, the debris will fall into the impurity removal frame 42 and fall into the inside of the collection box 43. The feces must have a large density, so it is not affected by the wind force and falls directly from the discharge frame 41 to the inner part of the upper barrel 31 below for transmission.

[0063] Combine Figure 8 : After collecting for a period of time, the user can pull out the collection box 43, and then the card plate 44 slides and separates from the debris removal frame 42, so that the collection box 43 can be taken out, so that the debris inside the collection box 43 can be processed.

[0064] The two clamping plates 44 are slidably connected to the lower surface of the impurity removal frame 42 , and the inner walls of the collecting box 43 and the impurity removal frame 42 are both inclined.

[0065] The inner wall of the loading barrel 31 and the two sides of the screw 35 are both attached with a first scraper 10 and a second scraper 11. A connecting plate 12 is fixed on the opposite side of the first scraper 10 and the second scraper 11. A limiting sleeve 13 is fixed on the side wall of the loading barrel 31. A push rod 14 is slidably connected to the inside of the limiting sleeve 13.

[0066] Combine Figure 4 and Figure 5: After the screw 35 rotates for a period of time, the user can push the push rod 14 to control the connecting plate 12 to drive the first scraper 10 and the second scraper 11 to slide on the inner wall of the upper barrel 31. When the first scraper 10 and the second scraper 11 are sliding, the inclined surfaces on both sides will scrape off the sticky feces remaining on the inner wall of the upper barrel 31 and drop it back onto the screw 35.

[0067] One end of the push rod 14 is fixedly connected to the top of the first scraper 10 . Both sides of the first scraper 10 and the second scraper 11 are inclined. The lower surface of the screw 35 fits tightly with the middle position of the inner wall of the upper barrel 31 .

[0068] Understandable: From Figure 6 It can be seen that the lower surface of the screw 35 fits with the inner wall of the upper barrel 31, so compared with the traditional design, the wear between the outer edge transition of the screw 35 and the inner wall of the upper barrel 31 can be reduced.

[0069] In this embodiment: the driving motor 32 drives the screw 35 to rotate, which can stably complete the rotational transmission of feces dropped from the discharge frame 41 inside the upper barrel 31, and during the feeding process, it can also drive the fan 47 to rotate to generate wind force, so that grass or wool and other hair in the feces can be removed, thereby ensuring that the quality of the final fermented product is higher. Secondly, compared with the traditional installation method of pipes and screws 35, the screw 35 of this case has less contact area with the upper barrel 31, which not only facilitates the preparation of the screw 35 and the upper barrel 31, but also the first scraper 10 and the second scraper 11 on the inclined surfaces on both sides can also effectively solve the feces adhering to the inner wall of the upper barrel 31, thereby solving the gap problem of the screw 35.

[0070] Second embodiment:

[0071] See also Figures 10 to 13 A stirring mechanism 5 is installed inside the fermentation tank 1, and the stirring mechanism 5 includes a mounting plate 51 fixed to the inner wall of the fermentation tank 1. A stirring motor 52 is installed on the upper surface of the mounting plate 51 by bolts. The output shaft keyway of the stirring motor 52 is connected to a rotating rod 53. A ratchet 54 is fixed on the outer wall of the rotating rod 53. A ferrule 55 is rotatably connected to the upper surface of the mounting plate 51 and located outside the ratchet 54. A ratchet 58 is installed on the inner wall of the ferrule 55. A collecting box 56 is fixed on the lower surface of the ferrule 55. A ring-shaped support rod 57 is fixed on the outer wall of the rotating rod 53 and located on the lower surface of the ratchet 54.

[0072] The inner bottom of the collecting box 56 is in a fine mesh grid structure, and the ratchet teeth 58 are engaged with the outer wall of the ratchet wheel 54 .

[0073] The collecting box 56 with a fine mesh grille structure is convenient for storing impurities such as foam and grease, and can ensure that normal organic fertilizer liquid can pass through smoothly.

[0074] Combine Figure 10 and Figure 11 : After the screw 35 is loaded, the user needs to add liquid and other additives required for fermentation into the fermentation tank 1. Before fermentation, it is necessary to start the stirring motor 52 to rotate counterclockwise. The counterclockwise rotating stirring motor 52 will drive the ratchet 54 and the rotating rod 53 to rotate at the same time. In this way, the rotating rotating rod 53 will control the support rod 57 to allow the feces and liquid inside the fermentation tank 1 to be fully mixed, which is convenient for subsequent fermentation.

[0075] Combine Figure 12 and Figure 13 :from Figure 10 It can be seen that when the fermentation tank 1 is in the final fermentation process, the internal liquid will produce a large amount of grease and expanded fermentation products. At this time, the liquid level in the fermentation tank 1 will rise to the position of the collection box 56. The collection box 56 is the limit position of the fermentation tank 1. Therefore, once the liquid level exceeds the collection box 56, the user needs to intervene to discharge the liquid in time. When the liquid level reaches the position of the collection box 56, the user needs to start the stirring motor 52 to rotate clockwise. At this time, the clockwise rotating ratchet 54 will control the ratchet 58 to drive the collection box 56 to rotate clockwise. Therefore, the clockwise rotating support rod 57 stirs the liquid surface to stir the floating objects in the middle and move them toward the liquid surface. At the same time, the collection box 56 rotates to collect the grease, floating objects, foam, etc. on the liquid surface.

[0076] Understandable: From Figure 12 It can be seen from the figure that the collecting box 56 can only work when the ratchet 54 rotates clockwise, and only the rotating rod 53 works when the ratchet 54 rotates counterclockwise, because the rotating rod 53 only performs stirring work when it rotates counterclockwise, and the collecting box 56 does not need to work at this time.

[0077] In this embodiment, the feces can be stirred well by the rotating rod 53 before fermentation, which is convenient for subsequent uniform fermentation. Secondly, after the fermentation is completed, the collecting box 56 can be controlled to rotate. The rotation of the collecting box 56 can well remove impurities such as foam and grease generated during the fermentation process, and the collecting box 56 also plays a pre-tightening role to prevent the liquid level from continuing to rise due to fermentation.

[0078] Third embodiment:

[0079] See also Figure 14 and Figure 16, further comprising a closing assembly 6 and a locking assembly 8, a flip assembly 7 is installed on the outside of the fermentation tank 1, the flip assembly 7 comprises a mounting seat 71 fixed to the outer wall of the fermentation tank 1, a flip motor 72 is mounted on the outer wall of the mounting seat 71 by bolts, the output shaft keyway of the flip motor 72 is connected to a cover body 73, a limiting groove 74 is provided on the upper surface of the cover body 73, a slider 75 is slidably connected to the inside of the limiting groove 74, and a through notch 76 is provided at the inner bottom of the limiting groove 74 and directly below the slider 75;

[0080] The closing assembly 6 includes a feed port 61 formed on and extending through the outer wall of the fermentation tank 1. A slide rod 62 is slidably connected to the upper surface of the feed port 61 and located on the inner wall of the fermentation tank 1. A closing plate 63 adapted to the feed port 61 is fixedly provided on the lower surface of the slide rod 62. Return springs 64 are fixedly provided on the upper surface of the closing plate 63 and located on both sides of the slide rod 62.

[0081] The locking assembly 8 includes two limit frames 81 fixed to the outer wall of the fermentation tank 1 and located on the opposite side of the mounting seat 71 and the closing plate 63. The interiors of the two limit frames 81 are slidably connected to the limit blocks 82. A positioning block 83 is fixed on the opposite side of the two limit blocks 82. A limit spring 84 is fixed inside the two limit frames 81 and on the outer wall of the two limit blocks 82.

[0082] Combine Figure 14 : During the feeding process, the feed port 61 is in an open state, and the fermentation tank 1 is also in an open state, which makes it convenient for the user to add liquid or additives required for fermentation.

[0083] Combine Figure 15 : When switching from the feeding state to the fermentation state, the user needs to start the flip motor 72 to control the cover body 73 to flip counterclockwise and close the fermentation tank 1. When the cover body 73 contacts the slide bar 62 and the positioning block 83, the slide bar 62 will be controlled to drive the closing plate 63 to descend, so that the descending closing plate 63 can seal the feed port 61. At this time, the return spring 64 is extended. If it is opened, the closing plate 63 will be reset to the raised state. Secondly, when the inclined surface of the positioning block 83 contacts the slider 75, it is subjected to a downward force to control the internal displacement of the positioning block 83 in the limit frame 81. At this time, the limit block 82 controls the limit spring 84 to be compressed.

[0084] Combine Figure 16 When the cover 73 is completely closed with the opening of the fermentation tank 1, the closing plate 63 is completely sealed with the feed port 61. When the slider 75 passes under the inclined surface of the positioning block 83, the limit spring 84 resets the control limit block 82 so that the positioning block 83 closes the cover 73.

[0085] Preferably, the closing plate 63 can be made of rubber.

[0086] The cover 73 is rotatably connected to the mounting seat 71 , the top ends of the two return springs 64 are fixedly connected to the inner wall of the fermentation tank 1 , and one ends of the two limit springs 84 are fixedly connected to the inner walls of the two limit frames 81 .

[0087] The two limit frames 81 , the two limit blocks 82 , the positioning block 83 and the two limit springs 84 are mirror-imaged on opposite sides of the axis of the fermentation tank 1 and are located at the same horizontal position.

[0088] from Figure 16 It can be seen that the positioning block 83 limits the cover body 73 through the upper surface of the force-bearing slider 75. Therefore, when fermentation is completed, the user can slide the slider 75 along the trajectory of the limiting groove 74 to make it misaligned with the positioning block 83, so that the notch 76 can be opened. Then, when the cover body 73 is flipped open, the notch 76 will pass through the positioning block 83 to ensure that the cover body 73 can be opened and closed smoothly.

[0089] In this embodiment: after the loading is completed, the fermentation tank 1 needs to be switched from the loading state to the fermentation state. During the switching process, the cover body 73 will be closed with the fermentation tank 1. During the switching process, the closing plate 63 can be directly controlled to descend to block the feed port 61. Secondly, the one-way control positioning block 83 directly locks the cover body 73. This not only can well isolate the fermentation tank 1, but also prevent miscellaneous bacteria from entering. At the same time, a large amount of expansion gas will be generated during the fermentation process, which is easy to cause danger. The cover body 73 can be positioned and locked by the positioning block 83, thereby achieving absolute safety during the fermentation process.

[0090] Please refer to Figures 1 to 16 The working principle of the fermentation equipment for treating organic liquid fertilizer provided by the present invention is as follows:

[0091] Step S1: Before fermentation, the collected feces need to be put down from the hopper 9, and the driving motor 32 is started to control the driving gear 33 to rotate clockwise. When the driving gear 33 rotates clockwise, it engages and drives the driven gear 34 to rotate counterclockwise. At this time, the counterclockwise rotating driven gear 34 controls the screw 35 to rotate inside the feeding barrel 31. The rotation of the screw 35 can transfer the feces dropped from the top through the feeding barrel 31 to the inside of the fermentation tank 1 for storage and fermentation. In the process of driving the screw 35 to rotate and feed the material, the driving pulley 45 on the output shaft of the driving motor 32 will also rotate clockwise and transmit the transmission through the belt 48 to control the rotation of the driven pulley 49. When the driven pulley 49 rotates clockwise, the driven pulley 49 rotates counterclockwise. When the pulley 49 rotates, it can drive the fan 47 to rotate inside the frame 46 to generate wind. In this way, when the falling feces passes through the wind generated by the fan 47, the wool, grass and other small-density debris will be blown away from the feces by the fan 47. Therefore, the debris will fall into the debris removal frame 42 and fall into the collection box 43. The feces must have a large density, so it is not affected by the wind and falls directly from the unloading frame 41 to the upper barrel 31 below for transmission. After collecting for a period of time, the user can pull the collection box 43, and then the card plate 44 slides and separates from the debris removal frame 42, so that the collection box 43 can be taken out, so that the debris inside the collection box 43 can be processed.

[0092] Step S2: After the screw 35 has finished loading, the user needs to add liquid and other additives required for fermentation into the fermentation tank 1. Before fermentation, the stirring motor 52 needs to be started to rotate counterclockwise. The counterclockwise rotating stirring motor 52 will drive the ratchet 54 and the rotating rod 53 to rotate at the same time. In this way, the rotating rotating rod 53 will control the support rod 57 to fully mix the feces and liquid inside the fermentation tank 1, which is convenient for subsequent fermentation. During the final fermentation process of the fermentation tank 1, the internal liquid will produce a large amount of grease and expanded fermentation products. At this time, the liquid level in the fermentation tank 1 is It will rise to the position of the collection box 56, which is the limit position of the fermentation tank 1. Therefore, once the liquid level exceeds the collection box 56, the user needs to intervene to discharge the liquid in time. When the liquid level reaches the position of the collection box 56, the user needs to start the stirring motor 52 to rotate clockwise. At this time, the clockwise rotating ratchet 54 will control the ratchet 58 to drive the collection box 56 to rotate clockwise. Therefore, the clockwise rotating support rod 57 stirs the liquid surface to stir the floating objects in the middle and move them toward the liquid surface. At the same time, the collection box 56 rotates to collect grease, floating objects, foam, etc. on the liquid surface.

[0093] When the lid 73 is completely closed with the opening of the fermentation tank 1, the closing plate 63 is completely closed and sealed with the feeding port 61. When the slider 75 passes under the inclined surface of the positioning block 83, the limiting spring 84 resets the limiting block 82 so that the positioning block 83 closes the lid 73.
