Description

Technical Field

[0001] The utility model relates to the technical field of fermentation equipment, in particular to a straw waste continuous fermentation reactor. Background Art

[0002] Straw fermentation is a straw processing method to improve the nutritional value of crop straw. After adding fermentation bacteria to the straw, the number of bacteria that decompose cellulose in the straw is greatly increased. Under suitable temperature, humidity and closed anaerobic conditions, the cellulose, hemicellulose and lignin in the straw are degraded in large quantities to produce sugars, which are then converted into lactic acid and volatile fatty acids, inhibiting the reproduction of harmful bacteria and putrefactive bacteria. After micro-storage, the straw is converted into high-quality fertilizer.

[0003] We know that during the straw sealing process, the straw raw material contains some oxygen, which allows aerobic microorganisms to grow and reproduce in the first few days of fermentation. Through the activity of these aerobic microorganisms, a small amount of sugar and oxygen in the straw can be converted into carbon dioxide and water. Finally, the oxygen becomes less and less until the oxygen content drops to zero. At this time, aerobic microorganisms cannot survive and finally all die. After the activity of aerobic microorganisms, the oxygen is consumed and aerobic microorganisms cannot survive. At this time, anaerobic microorganisms begin to move. Each time the fermentation tank is filled with straw and fermentation bacteria and then sealed, some oxygen will be carried in it. Each time new straw waste is loaded, the activity of anaerobic microorganisms will be inhibited, causing the straw fermentation process to be delayed. Utility Model Content

[0030] Fermentation vessel 1;

[0031] A feed hopper 2 is arranged above the fermentation container 1 and is used to input straw waste and fermentation bacteria into the fermentation container 1;

[0032] A partition plate is horizontally fixed inside the fermentation container 1;

[0033] The cylinder 3 is horizontally fixed inside the fermentation container 1 and cooperates with the partition plate to divide the internal space of the fermentation container 1 into an upper space and a lower space;

[0034] The inlet 4 and the outlet 5 are provided on the circumferential side wall of the cylinder 3, the inlet 4 corresponds to the upper space, and the outlet 5 corresponds to the lower space;

[0035] A plurality of rotating plates 6 are rotatably arranged inside the cylinder 3 so that the internal space of the cylinder 3 is divided into a plurality of identical fan-shaped spaces;

[0036] A lower hopper 7 is provided below the fermentation container 1 and is used to discharge high-quality fertilizer converted from straw;

[0037] Among them, the rotating plate 6 is driven by an electric drive device to rotate at a uniform speed inside the cylinder 3, so that the straw waste and fermentation bacteria in the upper space fall into each fan-shaped space in turn through the inlet 4. When the fan-shaped space is not connected with the inlet 4 and the outlet 5, the oxygen in the fan-shaped space is consumed by aerobic microorganisms and then discharged from the outlet 5 to the lower space.

[0038] Through the above technical scheme, the fermentation container 1 is divided into an upper and lower space, the upper space is used to hold straw waste and fermentation bacteria, and the fan-shaped space is rotated about the virtual central axis of the cylinder 3 through the rotatable rotating plate 6. The fan-shaped space has three states: connected with the inlet 4, connected with the outlet 5, and not connected with the inlet 4 and the outlet 5. The straw waste and fermentation bacteria in the upper space enter the fan-shaped space, consume oxygen in the fan-shaped space, and are finally discharged to the lower space, so that there is no oxygen in the lower space, and oxygen will not be carried over due to the addition of new straw waste and fermentation bacteria, thereby not repeatedly inhibiting the activity of anaerobic microorganisms, and accelerating the straw fermentation process.

[0039] The partition plate has two first inclined plates 8 and two second inclined plates 9, and the two first inclined plates 8 are symmetrically arranged with the center line of the fermentation container 1 as the symmetry line, and the two first inclined plates 8 are fixedly connected to the fermentation container 1, and the two second inclined plates 9 are fixedly connected to the two first inclined plates 8 respectively, and the two second inclined plates 9 are fixedly connected to the outer wall of the cylinder 3. Then, the straw waste and fermentation bacteria in the upper space move along the slopes of the first inclined plates 8 and the second inclined plates 9 toward the inlet 4 on the cylinder 3, so that they automatically enter the interior of the cylinder 3 through the inlet 4.

[0040] The electric drive device includes a rotating motor 10 and a reduction box 11, both of which are installed outside the fermentation container 1, the output end of the rotating motor 10 is fixedly connected to the input end of the reduction box 11, the output end of the reduction box 11 is fixedly connected to a rotating shaft 12, the rotating shaft 12 extends inward through the fermentation container 1, the outer wall of the rotating shaft 12 is fixedly connected to a plurality of rotating plates 6, the rotating shaft 12 is coaxially arranged with the cylinder 3, and the contact portion between the rotating plate 6 and the inner wall of the cylinder 3 is sealed and slidably arranged.

[0041] The rotating plate 6 is provided with a slide groove 13, and the slide groove 13 is slidably connected to the slide plate 14. A rubber block 15 is fixed on the side of the slide plate 14 corresponding to the inner wall of the cylinder 3. The rubber block 15 has an arc surface. A compression spring 17 is also arranged in the slide groove 13. The two ends of the compression spring 17 are respectively connected to the slide groove 13 and the slide plate 14. The elastic force of the compression spring 17 makes the rubber block 15 close to the inner wall of the cylinder 3.

[0042] The slide plate 14 is fixedly connected to the limit block 18 , and the rotating plate 6 is provided with a limit slot 19 . The limit block 18 and the limit slot 19 are slidably connected to each other, so as to limit the slide plate 14 from popping out of the slide slot 13 .

[0043] The fermentation container 1 is also fixedly connected to a fixed block 20 , on which a hydraulic cylinder 21 is mounted. An output shaft of the hydraulic cylinder 21 is fixedly connected to a slider 22 , which has a circular groove 23 that matches the lower hopper 7 . The fixed block 20 also has a slot 24 .

[0044] Working principle:

[0045] The straw waste and yeast can enter the fermentation container 1 through the feed hopper 2, and specifically fall into the upper space, and under the guidance of the slope of the partition plate, gradually fall into the cylinder 3 through the inlet 4;

[0046] The rotating plate 6 is driven by electricity to rotate slowly, and the straw waste and yeast fall into different fan-shaped spaces in turn. The fan-shaped spaces rotate slowly inside the cylinder 3. When the fan-shaped spaces are not connected to the inlet 4, the oxygen in the fan-shaped spaces will be continuously consumed until it disappears. As the fan-shaped spaces continue to rotate slowly to the outlet 5, the straw waste and yeast fall into the lower space for anaerobic fermentation.

[0047] The hydraulic cylinder 21 drives the slider 22 to slide and controls the position of the chute 13. When the chute 13 does not correspond to the lower hopper 7, the entire lower space is in a closed state. When the chute 13 corresponds to the lower hopper 7, the high-quality fertilizer converted in the lower space falls into the chute 13 through the lower hopper 7, and then moves with the chute 13, and is finally discharged through the slot 24.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
