Description

Technical Field

[0001] This utility model relates to the technical field of organic fertilizer fermentation devices, specifically an organic fertilizer fermentation device. Background Technology

[0002] Bio-organic fertilizer is an organic fertilizer made from organic solid waste through microbial fermentation, deodorization, and complete decomposition.

[0003] In traditional fermentation equipment, it is necessary to ensure that the fermentation device is sealed during the fermentation of organic fertilizer. However, a lot of gas is produced during fermentation, which needs to be released. Traditional equipment often uses valves to manually release the gas. During fermentation, the gas can only be released periodically. If the gas is not released in time, the pressure inside the fermentation device will increase. If the gas is not released in time, there will be certain safety risks. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This organic fertilizer fermentation device, through a release pipe installed on the top of the fermentation chamber and a fixing rod installed in the inner cavity of the release pipe, will push the sealing plug to move when the gas pressure in the inner cavity of the fermentation chamber increases. This causes the sealing plug to move upward, allowing the gas generated in the fermentation chamber to be released outward from the gap between the sealing plug and the release groove. This timely reduces the pressure in the fermentation chamber and avoids the problem of traditional equipment being unable to release the gas generated in the fermentation chamber in time, which leads to increased pressure and certain safety risks.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 An organic fertilizer fermentation device includes a support frame 1, a fermentation chamber 2 mounted on the outer wall of the support frame 1, a protective shell 3 mounted on the outer wall of the support frame 1, a stirring shaft 4 rotatably connected to the inner cavity of the fermentation chamber 2, a driven gear 5 fixedly mounted on the outer wall of the stirring shaft 4, a drive motor 6 fixedly mounted on the outer wall of the support frame 1, a drive gear 7 fixedly mounted on the power output shaft of the drive motor 6, a release pipe 8 mounted on the top of the fermentation chamber 2, a release groove 9 opened in the inner cavity of the release pipe 8, a fixing rod 10 fixedly mounted on the inner wall of the release groove 9, and a support spring 11 movably sleeved on the outer wall of the fixing rod 10. A floating plate 12 is movably sleeved on the outer wall of the 10. A sealing plug 13 is fixedly installed on the outer wall of the floating plate 12. A conduit 14 is installed on the top of the release pipe 8. A feeding box 16 is installed on the top of the fermentation chamber 2. A feeding bin 15 is fixedly installed on the top of the feeding box 16. A fixing plate 17 is fixedly installed on the outer wall of the feeding box 16. A movable plate 18 is installed on the outer wall of the fixing plate 17. A movable block 19 is fixedly installed on the outer wall of the movable plate 18. A return spring 20 is installed on the outer wall of the fixing plate 17. A sealing plate 21 is movably sleeved on the inner cavity of the feeding box 16. A limit plate 22 is fixedly installed on the outer wall of the movable plate 18.

[0022] In the above structure, by setting a drive motor 6 on the outer wall of the support frame 1 and a driven gear 5 on the outer wall of the stirring shaft 4, the drive motor 6 can drive the drive gear 7 when it rotates. Since the outer wall of the drive gear 7 meshes with the outer wall of the driven gear 5, the driven gear 5 and the stirring shaft 4 are driven, so that the stirring shaft 4 can stir in the inner cavity of the fermentation chamber 2, thereby realizing the stirring of the organic fertilizer in the inner cavity of the fermentation chamber 2.

[0023] In a preferred embodiment, the outer wall of the drive gear 7 meshes with the outer wall of the driven gear 5, and the diameter of the outer wall of the drive gear 7 is smaller than the diameter of the outer wall of the driven gear 5.

[0024] In the above structure, the drive motor 6 installed on the outer wall of the support frame 1 drives the drive gear 7 to rotate the driven gear 5, thereby driving the stirring shaft 4 so that the stirring shaft 4 can mix and stir the organic fertilizer in the inner cavity of the fermentation chamber 2.

[0025] In a preferred embodiment, the two ends of the outer wall of the support spring 11 are in contact with the outer wall of the floating plate 12 and the inner wall of the release groove 9, respectively, and the support spring 11 is made of high carbon steel.

[0026] In the above structure, the support spring 11 provided on the outer wall of the fixed rod 10 can support the floating plate 12 and the sealing plug 13 under the action of the support spring 11, so that the sealing plug 13 can stay in the inner cavity of the release pipe 8 and block the inner cavity of the release pipe 8, so that the inner cavity of the fermentation chamber 2 is in a closed state under the action of the sealing plug 13 and the sealing plate 21.

[0027] In a preferred embodiment, the outer diameter of the sealing plug 13 is equal to the inner diameter of the release tube 8, and the outer diameter of the sealing plug 13 is smaller than the inner diameter of the release groove 9.

[0028] In the above structure, the organic fertilizer in the fermentation chamber 2 will generate harmful waste gas after continuous fermentation by the sealing plug 13 in the inner cavity of the release pipe 8. The harmful waste gas will accumulate in the inner cavity of the fermentation chamber 2, which will cause the pressure in the inner cavity of the fermentation chamber 2 to increase continuously. When the pressure in the inner cavity of the fermentation chamber 2 increases to a certain level, it will push the sealing plug 13 to move upward to the position of the release groove 9. At this time, the gas will be released outward from the gap between the sealing plug 13 and the release groove 9.

[0029] In a preferred embodiment: the outer wall of the movable block 19 passes through the inner cavity of the fixed plate 17 and is connected to the outer wall of the movable plate 18, and the two ends of the return spring 20 are respectively connected to the outer walls of the movable block 19 and the fixed plate 17.

[0030] In the above structure, by providing a moving block 19 on the outer wall of the moving plate 18, the moving block 19 passes through the inner cavity of the fixed plate 17, thereby enabling the moving plate 18 to move back and forth along the outer wall of the fixed plate 17. When the moving plate 18 moves to the end away from the outer wall of the fixed plate 17, the return spring 20 can be stretched, so that the outer wall of the limiting plate 22 is disengaged from the outer wall of the closing plate 21.

[0031] In a preferred embodiment, the shape and size of the outer wall of the sealing plate 21 match the shape and size of the inner cavity of the feeding box 16, and the outer wall of the limiting plate 22 is in contact with the outer wall of the sealing plate 21.

[0032] In the above structure, the limiting plate 22 provided on the outer wall of the moving plate 18 moves towards the end close to the fixed plate 17 under the traction of the return spring 20, thereby causing the outer wall of the limiting plate 22 to adhere to the outer wall of the sealing plate 21, achieving the effect of fixing the sealing plate 21, thereby sealing the inner cavity of the feeding box 16, and ensuring that the inner cavity of the fermentation chamber 2 is in a closed state under the action of the sealing plug 13 and the sealing plate 21.

[0033] Working principle: During use, the above equipment, by pulling the limiting plate 22, causes the moving plate 18 to move along the outer wall of the fixed plate 17, thereby stretching the return spring 20. This allows the limiting plate 22 to separate from the outer wall of the sealing plate 21. Then, the limiting plate 22 is rotated upwards, further separating it from the outer wall of the sealing plate 21. The sealing plate 21 is then pulled out from the inner cavity of the feeding box 16, allowing organic matter to be filled into the inner cavity of the fermentation chamber 2 through the feeding box 16. After filling, the sealing plate 21 is pushed into the inner cavity of the feeding box 16, causing the outer wall of the limiting plate 22 to adhere to the outer wall of the sealing plate 21. Under the action of the return spring 20, the limiting plate 22 adheres to the outer wall of the sealing plate 21, thus fixing the sealing plate 21. As the organic matter in the inner cavity of the fermentation chamber 2 continues to ferment, waste gas is generated. This process causes the pressure inside the fermentation chamber 2 to continuously increase, thereby pushing the sealing plug 13 upward along the inner wall of the release tube 8. When the pressure inside the fermentation chamber 2 exceeds the supporting force of the support spring 11, the sealing plug 13 moves upward to the position of the release groove 9. At this time, the gas inside the fermentation chamber 2 will be released outward through the gap between the sealing plug 13 and the release groove 9 and enter the conduit 14. After the gas is released, and when the gas inside the fermentation chamber 2 is released outward, external air cannot enter the inner cavity of the fermentation chamber 2. Subsequently, the pressure inside the fermentation chamber 2 decreases. At this time, the sealing plug 13 will re-enter the inner cavity of the fermentation chamber 2 under the action of the support spring 11 to seal the inner cavity of the fermentation chamber 2. This ensures that the inner cavity of the fermentation chamber 2 is in a closed state, preventing external bacteria from entering the inner cavity of the fermentation chamber 2 and affecting the fermentation of organic matter.
