Technical Field
[0001] This utility model relates to the field of feed fermentation technology, specifically to a compound feed fermentation device. Background Technology
[0002] With the development of animal husbandry, fermented feed, due to its rich nutrition and easy digestibility, has become an important direction for improving the growth efficiency of poultry and livestock. However, existing feed fermentation equipment still has shortcomings in structural design and functional implementation. Traditional equipment mostly uses single-shaft stirring or fixed stirring blades, which easily produces a laminar flow effect, resulting in uneven feed mixing and affecting fermentation quality. In order to solve the above problems, this utility model provides a compound feed fermentation equipment. Utility Model Content
[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a compound feed fermentation device that uses spiral blades for stirring. During stirring, the blades both revolve around the axis of the fermentation tank and rotate on their own axis, which can avoid the laminar flow effect of traditional single-axis stirring and improve the stirring and mixing effect.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a compound feed fermentation device, comprising:
[0005] A fermentation tank, wherein the upper end of the fermentation tank is provided with a feed inlet and the lower end is provided with a discharge outlet, and the discharge outlet is provided with an electric valve inside;
[0006] Multiple stirring paddles, which, while stirring, revolve around the axis of the fermenter and rotate on their own axis.
[0007] A pressure relief pipe is fixedly connected to the outer side of the upper end of the fermenter.
[0008] Preferably, the plurality of stirring paddles are mounted on a support, which is located inside the fermenter and is driven by a motor mounted on the upper end face of the fermenter.
[0009] Preferably, the support includes:
[0010] The base plate and the top plate are connected to each other by a connecting shaft, which is fixedly connected to the motor shaft of the motor.
[0011] Preferably, the stirring paddle includes a paddle shaft, on which multiple paddle blades are fixedly connected, and the multiple paddle blades are distributed along the circumference of the paddle shaft.
[0012] Preferably, the propeller shaft is rotatably connected between the bottom plate and the top plate, and the upper end of the propeller shaft is fixedly connected to a gear through the top plate. The gear meshes with a gear ring fixedly connected to the inner side of the upper end of the fermenter.
[0013] Preferably, the blades are in the shape of a twisted spiral.
[0014] Preferably, the outlet end of the pressure relief pipe extends into the interior of the frame, the frame contains purification liquid, and the frame is mounted on the fermentation tank.
[0015] Preferably, a sealing plug is connected to the inner side wall of the lower end of the frame by a spring, and the sealing plug is inserted into and cooperates with the pressure relief pipe.
[0016] Preferably, the frame body is folded into two protrusions on the side near the fermentation tank, a fixed frame is fixedly connected to the side wall of the fermentation tank, and a bolt is provided at the bottom of the frame body. The bolt is threadedly connected to the fixed plate fixedly connected to the fermentation tank, and the upper end of the bolt abuts against the lower side of the frame body.
[0017] Preferably, a telescopic rod is provided between the sealing plug and the inner sidewall of the frame.
[0018] The beneficial effects of this utility model are as follows:
[0019] This invention achieves three-dimensional tumbling of feed through the combined motion of the stirring paddle's revolution and rotation, along with spiral twisting blades. The revolution of the stirring paddle drives the overall circulation of the material, while the rotation of the stirring paddle enhances the local shear force. Combined with the continuous pushing of the spiral blades, this avoids the laminar flow effect of traditional single-axis stirring and improves the mixing effect.
[0020] This invention achieves dual protection of safety and environmental protection through the setting of a pressure relief pipe and a purification liquid frame. The dynamic sealing structure composed of a spring and a sealing plug allows for adjustment of the height of the frame and the distance between the inner wall of the frame and the pressure relief pipe. This enables the adjustment of the pressure relief pipe's pressure relief threshold according to the type of feed being fermented, reducing the risk of tank explosion. Furthermore, the frame contains a purification liquid that can absorb harmful components in the discharged gas, preventing pollution from the discharged gas. Attached Figure Description

[0030] 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.
[0031] This utility model provides a compound feed fermentation device, such as Figures 1 to 6 As shown.
[0032] Example 1:
[0033] A compound feed fermentation device includes a fermentation tank 1, a pressure relief pipe 3, and multiple stirring paddles 2. The fermentation tank 1 adopts a cylindrical design, with a feed inlet at the top for feeding raw materials and a discharge outlet at the bottom. An electric valve is installed inside the discharge outlet. During feeding and fermentation, the electric valve is in a closed state. A removable sealing plate is installed at the feed inlet to ensure the airtightness of the fermentation process. When the feed needs to be discharged after fermentation, the electric valve can be opened.
[0034] The fermenter 1 is equipped with multiple sets of stirring paddles 2, which are distributed circumferentially along the axis of the fermenter 1. During the stirring process, the multiple sets of stirring paddles 2 revolve around the axis of the fermenter 1, and at the same time, the stirring paddles 2 rotate on their own axis. The revolve of the stirring paddles 2 will drive the overall circulation of the material inside the fermenter 1. The rotation of the stirring paddles 2 can enhance the local shear force, so that the material inside the fermenter 1 can be better mixed together, which can avoid the laminar flow effect of traditional single-axis stirring.
[0035] Example 2:
[0036] The stirring paddle 2 includes a paddle shaft 201, on which multiple spiral twisted blades 202 are fixedly connected, and the multiple blades 202 are distributed along the circumference of the paddle shaft 201.
[0037] The support 4 includes a bottom plate 401 and a top plate 402. The bottom plate 401 and the top plate 402 are connected to each other by a connecting shaft 403. The connecting shaft 403 is fixedly connected to the motor shaft of the motor 5. The motor 5 is installed on the upper end surface of the fermentation tank 1, and the motor shaft of the motor 5 extends through the fermentation tank 1 into the interior of the fermentation tank 1.
[0038] The propeller shaft 201 is rotatably installed between the bottom plate 401 and the top plate 402, and the upper end of the propeller shaft 201 extends through the top plate 402 to the top of the top plate 402 and is fixedly connected to the gear 404. The gear 404 meshes with the gear ring 6 fixedly connected to the inner side of the upper end of the fermenter 1.
[0039] When stirring, motor 5 starts, and the rotation of motor shaft of motor 5 will drive support 4 to rotate. The rotation of support 4 will drive stirring paddle 2 to revolve around the axis of fermentation tank 1. Under the action of gear 404 and gear ring 6, stirring paddle 2 will rotate on support 4. At the same time, since the shape of blade 202 is spiral, it can continuously push the material inside fermentation tank 1, further avoiding laminar flow effect.
[0040] Example 3:
[0041] The outlet of the pressure relief pipe 3 extends into the interior of the frame 7, which contains a purification liquid (different purification liquids are used depending on the type of material being fermented; when the fermented material produces acidic gas, an alkaline solution is used to neutralize the acidic gas). The frame 7 is installed on the fermentation tank 1. When the pressure relief pipe 3 releases pressure, the discharged gas is purified by the purification liquid, thus preventing the discharged gas from polluting the environment.
[0042] A sealing plug 9 is connected to the inner wall of the frame 7 by a spring 8. The sealing plug 9 is inserted into the pressure relief pipe 3. A telescopic rod 12 is connected between the sealing plug 9 and the inner side of the frame 7 to ensure the stable sliding of the sealing plug 9 and prevent it from tilting.
[0043] The frame 7 is folded at both ends on the side near the fermentation tank 1 to form a convex strip. The convex strip is slidably connected to the fixed frame 10 fixedly connected to the fermentation tank 1. A bolt 11 is provided at the bottom of the frame 7. The bolt 11 is threadedly connected to the fixed plate fixedly connected to the fermentation tank 1. The upper end face of the bolt 11 abuts against the lower end face of the frame 7. By rotating the bolt 11, the height of the upper end face of the bolt 11 can be controlled, thereby controlling the height of the frame 7. In turn, the distance between the inner side wall of the lower end of the frame 7 and the air outlet of the pressure relief pipe 3 can be controlled. The compression of the spring 8 can be adjusted, thereby adjusting the clamping force of the sealing plug 9 on the pressure relief pipe 3 and adjusting the pressure relief threshold of the pressure relief pipe 3.
[0044] The pressure relief threshold of the pressure relief pipe 3 can be adjusted according to the type of material being fermented. For example, when fermenting high-protein feed, the pressure relief threshold of the pressure relief pipe 3 can be increased (reducing the distance between the inner wall of the lower end of the frame 7 and the air outlet of the pressure relief pipe 3). When fermenting materials that are prone to gas production, the pressure relief threshold of the pressure relief pipe 3 can be decreased (increasing the distance between the inner wall of the lower end of the frame 7 and the air outlet of the pressure relief pipe 3).
[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
