Description

Technical Field

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

[0002] Organic fertilizers generally include two categories: inherent organic fertilizers and liquid organic fertilizers. They can reduce the use of edible plant fertilizers and pesticides to a certain extent, thereby reducing the impact of fertilizers and pesticides on the environment and human health. Organic liquid fertilizer is a new type of fertilizer with high concentration, high fertilizer efficiency, multi-function and full nutrition enhancement. Compared with traditional chemical fertilizers, it can be absorbed by plants in a very short time to avoid loss, and it is simple and convenient to apply and easy to 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 feces will be collected and finally concentrated in a fermentation tank. The feces will be fermented through various means such as liquid sealing, temperature control and oxygenation. The fermented liquid can be used as organic liquid fertilizer. In the prior art, the feces in the grassland will carry some sundries such as grass or wool 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 feces.

[0015] Compared with the related art, the motor structure provided by the present invention has the following beneficial effects: The driving motor controls the driving gear to rotate clockwise.

Through the rotation of the screw, the feces falling from the upper side can be transferred through the upper barrel to the inside of the fermentation tank for storage and fermentation. 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 to transmit the control through the belt to the driven pulley to rotate. 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 large density, so it is not affected by the wind force and falls directly from the unloading frame to the loading barrel below for transmission. The driving motor drives the screw to rotate, which can stably rotate and transmit the feces dropped from the feeding 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 final fermented product with higher quality. Secondly, compared with the traditional installation method of pipes and screws, the contact area between the screw and the feeding barrel 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 well solve the feces adhering to the inner wall of the feeding barrel, thereby solving the clearance problem of the screw.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] First embodiment: The invention provides a fermentation device for treating organic liquid fertilizer.

[0022] 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; 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; The feeding mechanism 3 includes a driving motor 32 mounted on the inner wall of the mounting frame 2, the output shaft of the driving motor 32 is keyed to a driving gear 33, a loading barrel 31 is fixedly disposed on the outer wall of the fermentation tank 1 and 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 keyed to the outer end axis of the screw 35; Combination Figure 3 : First, start the driving motor 32 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 upper barrel 31. Through the rotation of the screw 35, the feces falling from the top can be transferred through the upper barrel 31 to the inside of the fermentation tank 1 for storage and fermentation.

[0023] 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.

[0024] The impurity removal mechanism 4 includes a collecting box 43, a material discharge frame 41 is fixedly provided on the upper surface of the upper barrel 31, a impurity removal frame 42 is fixedly provided on the side wall of the material discharge 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 material discharge frame 41 and located in the same horizontal direction as the impurity removal frame 42, a fan 47 is rotatably installed inside the frame 46, a driven pulley 49 is connected to the keyway at the back of the frame 46 and located at the axis of the fan 47, a driving pulley 45 is connected to the keyway on the outer wall 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 material discharge frame 41; Combination Figure 7 and Fig. 9Before 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 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 collection box 43. The feces must have a large density, so it is not affected by the wind force and falls directly from the unloading frame 41 to the lower feeding barrel 31 through transmission.

[0025] Combination 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.

[0026] The two clamping plates 44 are slidably connected to the lower surface of the impurity removing frame 42 , and the inner walls of the collecting box 43 and the impurity removing frame 42 are both inclined.

[0027] The inner wall of the loading barrel 31 and the two sides of the screw 35 are both attached with the first scraper 10 and the second scraper 11, and the first scraper 10 and the second scraper 11 are fixedly provided with a connecting plate 12 on the opposite side, and the side wall of the loading barrel 31 is fixedly provided with a limiting sleeve 13, and the inside of the limiting sleeve 13 is slidably connected with a push rod 14.

[0028] Combination 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.

[0029] 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 .

[0030] Understandable: From Figure 6 It can be seen that the lower surface of the screw 35 is in contact 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.

[0031] 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, the fan 47 can also be driven 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 well solve the feces adhering to the inner wall of the upper barrel 31, thereby solving the gap problem of the screw 35.

[0032] Second embodiment: 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, and a rotating rod 53 is connected to the output shaft keyway of the stirring motor 52, and a ratchet 54 is fixed on the outer wall of the rotating rod 53, and a ferrule 55 is rotatably connected to the upper surface of the mounting plate 51 and located outside the ratchet 54, and a ratchet 58 is installed on the inner wall of the ferrule 55, and a collecting box 56 is fixed on the lower surface of the ferrule 55, and a ring-distributed support rod 57 is fixed on the outer wall of the rotating rod 53 and located on the lower surface of the ratchet 54.

[0033] The inner bottom of the collecting box 56 is in a fine mesh grid structure, and the ratchet teeth 58 are meshed with the outer wall of the ratchet wheel 54 .

[0034] The collecting box 56 of fine mesh grille structure is convenient for storing impurities such as foam and grease, and can ensure that normal organic fertilizer liquid can pass smoothly.

[0035] Combination Fig.10 and Fig.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.

[0036] Combination Fig.12 and Fig.13 :from Fig.10It can be seen that when the fermentation tank 1 is in the final fermentation process, the internal liquid will produce a large amount of oil 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 to move toward the liquid surface. At the same time, the collection box 56 rotates to collect the oil, floating objects, foam, etc. on the liquid surface.

[0037] Understandable: From Fig.12 It can be seen 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.

[0038] 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 impurities such as foam and grease generated during the fermentation process can be removed well through the rotation of the collecting box 56. The collecting box 56 also plays a pre-tightening role to prevent the liquid level from continuing to rise due to fermentation.

[0039] Third embodiment: See also Fig.14 and Fig.16 , further comprising a closing component 6 and a clamping component 8, a flip component 7 is installed on the outside of the fermentation tank 1, the flip component 7 comprises a mounting seat 71 fixed to the outer wall of the fermentation tank 1, a flip motor 72 is installed on the outer wall of the mounting seat 71 by bolts, the output shaft keyway of the flip motor 72 is connected with 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 inside 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; The closing assembly 6 comprises a feed port 61 which is opened on the outer wall of the fermentation tank 1 and passes through the fermentation tank 1. A slide bar 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 which matches the feed port 61 is fixedly arranged on the lower surface of the slide bar 62. Return springs 64 are fixedly arranged on the upper surface of the closing plate 63 and located on both sides of the slide bar 62. 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 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 walls of the two limit blocks 82.

[0040] Combination Fig.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, so that the user can add the liquid or additives required for fermentation.

[0041] Combination Fig.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 reset spring 64 is extended. If it is opened, the closing plate 63 will reset to the raised state. Secondly, when the inclined surface of the positioning block 83 contacts the slider 75, it is subjected to the downward force to control the positioning block 83 to move inside the limit frame 81. At this time, the limit block 82 controls the limit spring 84 to be compressed.

[0042] Combination Fig.16 When the cover 73 is completely closed with the mouth of the fermentation tank 1, the closing plate 63 is completely closed and 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.

[0043] Preferably, the closing plate 63 can be made of rubber material.

[0044] The cover body 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 .

[0045] The two limit frames 81 , the two limit blocks 82 , the positioning block 83 and the two limit springs 84 are mirror-distributed on opposite sides of the axis of the fermentation tank 1 and are located at the same horizontal position.

[0046] from Fig.16It 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 the 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 freely.

[0047] 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.

[0048] 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: 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 meshes 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 loading barrel 31. Through the rotation of the screw 35, the feces dropped from the top can be transferred through the loading barrel 31 to the inside of the fermentation tank 1 for storage and fermentation. During the process of driving the screw 35 to rotate and feed, the driving pulley 45 on the output shaft of the driving motor 32 will also rotate clockwise and transmit through the belt 48 to control the rotation of the driven pulley 49. When the 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, 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 force 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.

[0049] Step S2: 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, 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 allow the feces and liquid inside the fermentation tank 1 to be fully mixed, which is convenient for subsequent fermentation. In 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 to move toward the liquid surface. At the same time, the collection box 56 rotates to collect grease, floating objects, foam, etc. on the liquid surface.

[0050] Step S3: 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 reset spring 64 is extended. If it is opened, the closing plate 63 will be reset to the rising state. Secondly, when the inclined surface of the positioning block 83 contacts the slider 75, it is subjected to the 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 compress. When the cover body 73 is completely closed with the tank mouth of the fermentation tank 1, the closing plate 63 is completely closed and 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 body 73.
