In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.
[0028] Example 1
[0029] like Figure 1-Figure 8 A novel fermentation device for producing high-efficiency organic fertilizer from animal manure comprises a fermentation tank 1 and a driving mechanism 3.
[0030] The fermentation tank 1 is used to hold livestock manure, and includes a base 11, an outer tank 12, an inner tank 13, an opening and closing door 14, and a stirring member 15. The base 11 is placed on the ground, the outer tank 12 is rotatably connected to the base 11 in a horizontal posture, the inner tank 13 is coaxially fixedly connected to the inside of the outer tank 12, and a space is reserved between the outer tank 12 and the inner tank 13, and the space is used to collect the filtrate. A plurality of stirring members 15 are fixed inside the inner tank 13, so that when the outer tank 12 and the inner tank 13 rotate synchronously, the livestock manure inside the inner tank 13 will turn over, thereby increasing the frequency of contact with oxygen in the air, thereby improving the fermentation effect.
[0031] The outer tank 12 and the inner tank 13 are connected by a connecting pipe, and external feces can be sent into the inner tank 13 through the connecting pipe. The outer side of the outer tank 12 is hinged to the opening and closing door 14. The opening and closing door 14 can be opened when necessary to facilitate the user to input feces into the inner tank 13 or take feces out of the inner tank 13. The opening and closing door 14 and the outer tank 12 are stably connected by bolt fasteners.
[0032] The driving mechanism 3 is used to drive the outer tank 12 and the inner tank 13 to rotate relative to the base 11, and includes a motor 31, a driving gear 32, and a driven gear 33. The outer shell of the motor 31 is fixed on the base 11, the output shaft of the motor 31 is fixedly connected to the driving gear 32, and the driven gear 33 is fixed on the outer tank 12. The driving gear 32 and the driven gear 33 are meshed for transmission. When the motor 31 rotates, it can drive the outer tank 12 to rotate, thereby achieving the purpose of turning over the feces in the inner tank 13.
[0033] The inner tank 13 includes a bearing section and a filtering section. The bearing section is a cylinder with closed sides, and the filtering section is a cylinder with filter holes on the sides.
[0034] The cleaning mechanism 2 also included in the device is used to intermittently clean the filter section of the inner tank 13, and mainly includes a blocking member 21, a chute 22, and a filter brush 23. The blocking member 21 is placed between the base 11 and the outer tank 12, and a chute 22 is provided on the end surface of the outer tank 12. The filter brush 23 is arranged in the space, and the filter brush 23 slides against the outer side surface of the filter section of the inner tank 13. By allowing the blocking member 21 and the filter brush 23 to interfere with each other, and allowing the filter brush 23 and the inner tank 13 to rotate relative to each other during the interference process, the purpose of allowing the filter brush 23 to rub the outer side surface of the filter section is achieved, and the fertilizer blocked on the filter section of the filter brush 23 is pushed out of the filter hole.
[0035] The filter brush 23 includes a brush part and a support part. The support part is a mesh plate with gaps. A plurality of brushes are fixed on the mesh plate. The brushes are used to rub against the outer side surface of the inner tank 13. The filter brush 23 is rotatably connected to the end surface of the inner tank 13.
[0036] Specifically, in this embodiment, there are two structures of the blocking member 21 .
[0037] One of the structures of the blocking member 21 is as follows: the blocking member 21 includes a protrusion and a retraction block, the protrusion is fixed on the base 11, one end of the filter brush 23 extends outward and passes through the slide groove 22, the retraction block and the filter brush 23 are elastically slidably connected at one end outside the slide groove 22, and the protrusion is located on the moving path of the retraction block, one side of the retraction block is an inclined surface, and contacts the protrusion through the inclined surface. During the process of turning the fertilizer, the chute 22 and the filter brush 23 will rotate with the outer tank 12. When the filter brush 23 drives the shrinkage block and the protrusion to interfere with each other, the shrinkage block is initially blocked by the protrusion and drives the filter brush 23 and the inner and outer tanks to rotate relative to each other, so that the filter brush 23 can rotate relative to the inner tank 13 and can brush off the feces stuffed on the filter section of the inner tank 13. When the end of the chute 22 drives the shrinkage block and the protrusion to further interfere with each other, the shrinkage block is contracted by the pressure of the protrusion and separates from the protrusion. After the shrinkage block passes over the protrusion, the shrinkage block pops up again under the action of elastic force and rotates with the inner tank 13. This is repeated to achieve that the filter brush 23 can clean the filter section of the inner tank 13 once every time the inner and outer tanks rotate one circle.
[0038] Another structure of the blocking member 21 is as follows: the blocking member 21 includes an electromagnet, a magnet and a slide bar, the electromagnet is fixedly connected to the base 11, one end of the filter brush 23 extends outward and passes through the slide slot 22, the slide bar is fixedly connected to the end of the filter brush 23 located outside the slide slot 22, the magnet and the slide bar are elastically slidably connected, and the electromagnet is electrically connected to the external controller. The external controller can control the timing of the electromagnet to be powered on. When the filter brush 23 moves to the side where the electromagnet is located, the external controller controls the current to enter the electromagnet, the electromagnet is powered on to generate magnetic attraction to the magnet, the magnet overcomes the elastic force and drives the slide bar and the electromagnet to fit together, at this time the filter brush 23 is pulled by the magnetic force and rotates relative to the inner tank 13, until the end of the slide slot 22 contacts the filter brush 23, the external controller controls the electromagnet to be powered off, the magnetism disappears, the magnet retracts, and no longer interferes with the electromagnet, at this time the filter brush 23 and the inner tank 13 can rotate together, and so on repeatedly.
[0039] The two types of blocking members 21 each have their own advantages. The combination of the shrinkage block and the protrusion is based on a mechanical structure, which is simple in structure and low in cost. The combination of the electromagnet and the magnet requires access to a control system to achieve that when necessary, such as after the outer tank 12 rotates 10 times, the external controller controls the filter brush 23 to intervene for cleaning, making the timing of intervention of the filter brush 23 more flexible.
[0040] Furthermore, the end surface of the inner tank 13 near the filter brush 23 is closed, so that feces will not accidentally splash out through the chute 22 while turning the manure.
[0041] Example 2
[0042] like Figure 1-Figure 4 On the basis of Example 1, a certain inclination angle is maintained between the axis of the outer tank 12 and the inner tank 13 and the horizontal plane, so that one end of the outer tank 12 and the inner tank 13 is higher than the other end, and the end where the filter brush 23 is located is located at the lower end. In this way, during the stirring process, the liquid will gradually flow to the lower end and all fall into the space through the filtering effect of the filter brush 23.
[0043] Preferably, the inclination angle is 3°, which is conducive to the liquid flowing to the filtering section and can also effectively prevent the feces from sliding toward the filtering section during the stirring process.
[0044] Furthermore, the infusion mechanism 4 includes a limiting ring 41, a pipeline 42, and a pump 43. The limiting ring 41 is rotatably connected to the end of the outer tank 12, the limiting ring 41 is fixedly connected to the base 11, the bottom of the limiting ring 41 is connected to the input end of the pump 43 through the pipeline 42, the corresponding parts of the outer tank 12 and the limiting ring 41 are provided with leakage holes, the pipeline 42 is connected to the space through the leakage hole, the output end of the pump 43 is connected to the rotation center of the outer tank 12, and the pump 43 is used to re-quantitatively input the filtered water into the livestock manure in the inner tank 13 according to the needs of the user, so as to improve the fermentation efficiency of the manure.
[0045] In summary, the advantages of the present application are: by setting the blocking member 21, without interfering with the turning of the fertilizer in the outer tank 12 and the inner tank 13, the filter brush 23 and the filter section of the inner tank 13 are driven to rotate relative to each other, and the feces residue stuck on the filter section of the inner tank 13 is cleared, without the need to additionally set up a motor and a stirring member, so the present design can achieve the purpose of energy saving and high efficiency.
