Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural waste fermentation technology, and in particular to an agricultural straw waste fermentation device. Background Technology
[0002] The annual output of straw is enormous. Traditional methods of disposal, such as burning and piling, release harmful gases, breed pests, and seriously pollute the environment. However, straw is rich in cellulose and other components, which can be fermented into organic fertilizer and other resources. Driven by environmental protection policies, fermentation devices have become key equipment for the resource utilization of straw. However, existing devices have obvious shortcomings. First, the pretreatment is inadequate, and the straw is not crushed enough, which affects the efficiency of microbial decomposition. Second, the mixing is insufficient, which easily leads to straw clumping, resulting in uneven local fermentation and reducing the quality and efficiency of fermentation. Utility Model Content
[0003] The main purpose of this invention is to provide a fermentation device for agricultural straw waste, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An agricultural straw waste fermentation device includes two reinforcing ring blocks. Four reinforcing leg frames are fixedly connected to the outer surfaces of the two reinforcing ring blocks. The four reinforcing leg frames are arranged in a circular array. A fermentation tank is fixedly connected to the two reinforcing leg frames. A control key is provided on the front of the outer surface of the fermentation tank. A sealing cover is provided at the upper end of the fermentation tank. A feed hopper is fixedly connected to the upper right part of the sealing cover. A fine crushing and stirring device is fixedly connected to the upper middle part of the sealing cover. Preferably, the fine grinding and stirring device includes a driver, the output end of which passes through the upper middle part of the sealing cover and is fixedly connected to a connecting column, two upper grinding components are fixedly connected to the upper part of the outer surface of the connecting column, a middle filter plate is fixedly connected to the middle part of the outer surface of the connecting column, a plurality of through filter holes are opened at the upper end of the middle filter plate, and a bottom anti-stick stirring component is fixedly connected to the lower part of the outer surface of the connecting column.
[0005] By adopting the above technical solution: the driver drives the connecting column, which causes the upper crushing component to crush the straw, the middle filter plate to screen it, and the bottom component to stir and prevent sticking, thereby improving the crushing and stirring effect and promoting fermentation.
[0006] Preferably, the diameter of the intermediate filter plate is equal to the inner diameter area of the fermentation tank, and the intermediate filter plate is in close contact with but not fixed to the inner wall of the fermentation tank.
[0007] By adopting the above technical solution: the diameter of the middle filter plate is equal to the inner diameter of the fermentation tank, it is close to the inner wall but not fixed, and it can rotate with the connecting column to intercept insufficiently crushed straw, ensuring that the straw entering the lower part is crushed in place, thereby improving fermentation efficiency.
[0008] Preferably, the upper crushing component includes an upper ring block, which is fixedly connected to the connecting column through an insertion. Four blades are fixedly connected in a ring array on the outer surface of the upper ring block, and three sharp crushing blades are fixedly connected to one end of each of the four blades that are close to each other.
[0009] By adopting the above technical solution: the blade rod rotates with the connecting column, and the blade head quickly cuts the straw, achieving fine crushing, which is conducive to microbial decomposition and shortens the fermentation cycle.
[0010] Preferably, the two upper crushing components are located in the upper part of the fermentation tank, and the two upper crushing components are symmetrically distributed vertically.
[0011] By adopting the above technical solution, two upper crushing components are located at the top of the fermentation tank and are symmetrical, which double crushes the straw, improves the uniformity and efficiency of crushing, avoids incomplete crushing by a single component, and lays the foundation for subsequent fermentation.
[0012] Preferably, the bottom anti-stick stirring assembly includes a lower ring block, and two lower ring blocks are provided. The front and rear parts of the outer surfaces of the two lower ring blocks are fixedly connected to a beater frame. Five blades are fixedly connected to opposite ends of the two beater frames, and three beater rods are fixedly connected to the middle of the ends of the two beater frames that are close to each other.
[0013] By adopting the above technical solution—cutting straw with blades and beating with a patting rod to prevent sticking—the straw is allowed to come into full contact with microorganisms, thus improving the fermentation effect.
[0014] Preferably, the two lower ring blocks are fixedly connected to the lower part of the outer surface of the connecting column, and the two tapping frames are distributed in a mirror image arrangement and do not contact the inner wall of the fermenter.
[0015] By adopting the above technical solution: the lower ring block is fixed to the connecting column, the beater frame is distributed in a mirror image and does not contact the tank wall, ensuring stable rotation of the components, avoiding friction with the tank wall and damaging the equipment, while efficiently stirring the straw at the bottom.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the driver drives the connecting column to rotate, so that the blade and blade head of the upper crushing component can perform double fine crushing of the straw. The symmetrical distribution of the upper and lower parts makes the crushing more uniform. The middle filter plate rotates with the connecting column to intercept the straw that has not been fully crushed and make it continue to be crushed, ensuring that the straw is thoroughly crushed. The bottom anti-stick stirring component can stir the straw to prevent clumping. Overall, it increases the contact area between the straw and microorganisms, accelerates the decomposition efficiency, shortens the fermentation cycle, and improves the fermentation quality.
[0017] 2. In this utility model, the two lower ring blocks of the bottom anti-stick stirring component are fixed to the connecting column, which drives the front and rear mirror-distributed beating frames to rotate. The blades at opposite ends of the beating frames can further cut the straw, and the beating rods at the close ends can beat the straw. The beating frames do not contact the inner wall of the fermentation tank. This combination can effectively prevent the straw from clumping, allow the straw to fully contact the microorganisms, avoid uneven local fermentation, improve the fermentation quality and efficiency, and protect the device to ensure stable operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Please see Figure 1-4 This utility model provides a technical solution: A fermentation device for agricultural straw waste includes two reinforcing ring blocks 1. The outer surfaces of the two reinforcing ring blocks 1 are fixedly connected to four reinforcing leg frames 2, which are arranged in a circular array. A fermentation tank 3 is fixedly connected to the two reinforcing leg frames 2. A control key 4 is provided on the front of the outer surface of the fermentation tank 3. A sealing cover 5 is provided on the upper end of the fermentation tank 3. A feed hopper 6 is fixedly connected to the upper right side of the sealing cover 5. A fine crushing and stirring device 7 is fixedly connected to the upper middle part of the sealing cover 5.
[0024] In this embodiment, the fine grinding and stirring device 7 includes a driver 71. The output end of the driver 71 passes through the upper middle part of the sealing cover 5 and is fixedly connected to a connecting column 72. Two upper grinding components 73 are fixedly connected to the upper part of the outer surface of the connecting column 72. A middle filter plate 74 is fixedly connected to the middle part of the outer surface of the connecting column 72. Several through filter holes 75 are opened at the upper end of the middle filter plate 74. A bottom anti-stick stirring component 76 is fixedly connected to the lower part of the outer surface of the connecting column 72. The diameter of the middle filter plate 74 is equal to the inner diameter area of the fermentation tank 3. The middle filter plate 74 is in close contact with the inner wall of the fermentation tank 3 but not fixed. The upper grinding component 73 includes an upper ring block 731. The upper ring block 731 is inserted and fixedly connected to the connecting column 72. Four blades 732 are fixedly connected in a ring array on the outer surface of the upper ring block 731. Three sharp grinding blades 733 are fixedly connected to the ends of the four blades 732 that are close to each other. The two upper grinding components 73 are located in the upper part of the fermentation tank 3 and are symmetrically distributed vertically.
[0025] Through the above scheme: the driver 71 drives the connecting column 72 to rotate, which in turn drives the two symmetrical upper crushing components 73 to operate. The blade 732 fixed by the upper ring block 731 rotates with it, and the sharp crushing head 733 finely crushes the straw. The middle filter disc 74 rotates with the connecting column 72. Its diameter is equal to the inner diameter of the fermentation tank 3 and it is close to the inner wall. The filter disc intercepts the straw that is not fully crushed through the large filter holes 75, so that it can continue to be crushed in the upper part. Therefore, by combining double crushing with filtration and interception, the straw is fully crushed, the contact area with microorganisms is increased, the decomposition efficiency is improved, the fermentation cycle is shortened, and a good foundation is laid for subsequent fermentation.
[0026] In this embodiment, the bottom anti-stick stirring assembly 76 includes a lower ring block 761. Two lower ring blocks 761 are provided. The front and rear parts of the outer surfaces of the two lower ring blocks 761 are fixedly connected to a beater frame 762. Five blades 764 are fixedly connected to opposite ends of the two beater frames 762. Three beater rods 763 are fixedly connected to the middle of the ends of the two beater frames 762 that are close to each other. The two lower ring blocks 761 are fixedly connected to the lower part of the outer surface of the connecting column 72. The two beater frames 762 are distributed in a mirror image and do not contact the inner wall of the fermenter 3.
[0027] Through the above scheme: the connecting column 72 drives the lower ring block 761 to rotate, causing the front and rear mirror-distributed beating frames 762 to rotate accordingly. The blades 764 at the opposite ends further cut the straw at the bottom, and the beating rods 763 at the close ends beat the straw. Since the beating frames 762 do not contact the inner wall of the fermentation tank 3, friction damage can be avoided. Therefore, through multiple functions, the straw is prevented from clumping, allowing the straw to fully contact the microorganisms, solving the problem of uneven local fermentation, improving the fermentation quality and efficiency, and ensuring the stable operation of the device.
[0028] It should be noted that this utility model is an agricultural straw waste fermentation device. In use, firstly, the straw enters the fermentation tank 3 from the feed hopper 6. The reinforcing ring block 1 and the reinforcing leg frame 2 stabilize the support device. The driver 71 is started by the control key 4, which drives the connecting column 72 to rotate. The upper ring block 731 of the upper crushing component 73 rotates accordingly, so that the sharp crushing head 733 on the blade 732 crushes the straw. The two symmetrical upper crushing components 73 improve the crushing effect. The middle filter plate 74 rotates with the connecting column 72. Because its diameter is equal to the inner diameter of the fermentation tank 3 and it is close to the inner wall, it intercepts the straw that is not fully crushed through the large filter hole 75. The connecting column 72 drives the lower ring block 761 to rotate, so that the beater frame 762 operates. The blade 764 cuts the straw, and the beater rod 763 beats to prevent sticking. The sealing cover 5 ensures the airtightness. Thus, this device can efficiently process straw, improve fermentation efficiency and quality, and realize resource utilization.
