[0028] 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.
[0029] Please see Figure 1-7 The present invention provides the following technical solution:
[0030] A continuous anaerobic fermentation reactor for microbial fermentation of carbon source of grain by-products includes a reactor body 1. The top of the reactor body 1 is fixedly connected to an exhaust pipe 17. Several support legs 18 are fixedly connected to the surface of the reactor body 1. The bottom of the support legs 18 is fixedly connected to a bottom plate 6. A receiving box 2 is set on the top of the bottom plate 6. A material blocking mechanism 5 is set inside the receiving box 2. Limiting mechanisms 3 are set on both sides of the receiving box 2. A discharge pipe 19 is fixedly connected to the front of the reactor body 1.
[0031] The material blocking mechanism 5 includes two brackets 501, a fixing ring 502 and a rubber tube 503. The side of the bracket 501 near the fixing ring 502 is fixedly connected to the fixing ring 502. The surface of the bracket 501 is fixedly connected to the inner wall of the receiving box 2. The side of the rubber tube 503 near the fixing ring 502 is fixedly connected to the fixing ring 502. The discharge pipe 19 is located inside the fixing ring 502.
[0032] In this embodiment: biogas, biogas slurry, and biogas residue are produced by the anaerobic fermentation of grain by-products by microorganisms inside the reactor body 1. The biogas is discharged through the exhaust pipe 17. When discharging biogas slurry and biogas residue, the receiving box 2 is pushed first, so that the bottom roller 7 enters the limiting groove 14 along the chamfer 16 of the limiting groove 14. The handle 4 makes movement more convenient. The limiting mechanism 3 is operated, and the limiting pin 303 is inserted into the insertion hole 302 of the limiting frame 301 and extends to the limiting hole 15 of the bottom plate 6. The magnetic block 9 is magnetically attracted to the limiting frame 301 to prevent the limiting pin 303 from falling out. The pull ring 10 facilitates operation. At this time, the discharge pipe 19 is located in the fixing ring 502 of the baffle mechanism 5. The fixing ring 502 is fixed by the bracket 501. With the rubber hose 503 in place, the discharge pipe 19 is opened, and the biogas slurry and biogas residue enter the rubber hose 503 through the discharge pipe 19. The rubber hose 503 is flexible and can prevent splashing. When the material enters the receiving box 2, it squeezes the baffle 8 between the limiting frames 12, so that the baffle 8 and the silicone sealing gasket 13 are in close contact to enhance the seal. The handle 11 makes it easy to remove the baffle 8 to discharge the biogas slurry and biogas residue inside the receiving box 2. This solves the problem that some existing reactors for continuous anaerobic fermentation of grain by-products do not have a splash-proof structure at the discharge port. When biogas slurry and biogas residue need to be received and transferred over long distances, splashing is likely to occur during the discharge process, which contaminates the body and working environment of the operators.
[0033] Specifically, such as Figure 2 and Figure 4 As shown, the limiting mechanism 3 includes a limiting frame 301, a socket 302 and a limiting pin 303. The limiting frame 301 is fixedly connected to the receiving box 2 on the side near the receiving box 2. The socket 302 is opened inside the limiting frame 301 and the limiting pin 303 is movably inserted into the socket 302.
[0034] Specifically, such as Figure 4 and Figure 7 As shown, limit holes 15 are provided on both sides of the base plate 6, and limit pins 303 are movably inserted into the inside of the limit holes 15.
[0035] Specifically, such as Figure 4 As shown, a magnetic block 9 is fixedly connected to the surface of the limiting pin 303, and the surface of the magnetic block 9 is magnetically attracted to the surface of the limiting frame 301. A pull ring 10 is fixedly connected to the surface of the magnetic block 9.
[0036] In this embodiment: the limiting frame 301 is fixed to the receiving box 2, and the limiting pin 303 is inserted into the limiting hole 15 of the base plate 6 through the insertion hole 302, which can stably limit the position of the receiving box 2 and prevent it from moving during material discharge. The magnetic block 9 is magnetically attracted to the limiting frame 301, which can prevent the limiting pin 303 from accidentally coming out. The pull ring 10 makes it easy to insert and remove the limiting pin 303, which improves the reliability of the positioning of the receiving box 2 and the ease of operation.
[0037] Specifically, such as Figure 2 As shown, the bottom of the receiving box 2 is rotatably connected to rollers 7, and there are several rollers 7 symmetrically distributed on both sides of the bottom of the receiving box 2.
[0038] Specifically, such as Figure 1 , Figure 2 and Figure 7 As shown, limit grooves 14 are provided on both sides of the top of the base plate 6, and the rollers 7 are movably disposed inside the limit grooves 14.
[0039] Specifically, such as Figure 2 and Figure 7 As shown, chamfers 16 are provided on the front sides of both sides of the inner wall of the limiting groove 14, and a handle 4 is fixedly connected to the front side of the receiving box 2.
[0040] In this embodiment: the symmetrical rollers 7 at the bottom of the receiving box 2 facilitate flexible movement, and the limiting groove 14 of the base plate 6 can guide and limit the rollers 7 to prevent the receiving box 2 from shifting. The chamfer 16 of the limiting groove 14 facilitates the smooth entry of the rollers 7, and the handle 4 improves the convenience of pushing the receiving box 2, making the movement and alignment of the receiving box 2 more efficient.
[0041] Specifically, such as Figure 5 and Figure 6 As shown, the front and rear sides of the inner wall of the receiving box 2 are fixedly connected to the limiting frame 12, and the baffle 8 is movably inserted between the opposite sides of the two limiting frames 12.
[0042] Specifically, such as Figure 5 and Figure 6 As shown, a silicone sealing gasket 13 is fixedly connected to the front side of the rear limiting frame 12, and the rear side of the baffle 8 is in close contact with the front side of the silicone sealing gasket 13.
[0043] Specifically, such as Figure 5 As shown, handles 11 are fixedly connected to both sides of the top of the baffle 8.
[0044] In this embodiment: the limiting frame 12 inside the receiving box 2 can stably support the baffle 8, the silicone sealing gasket 13 enhances the sealing between the baffle 8 and the rear limiting frame 12, preventing the leakage of biogas slurry and biogas residue, and the handle 11 facilitates quick pick-up and drop-off of the baffle 8, making it convenient to discharge the biogas slurry and biogas residue in the receiving box 2. Overall, the sealing and ease of operation of biogas slurry and biogas residue collection and discharge are optimized.
[0045] Working principle: This continuous anaerobic fermentation reactor for grain by-products uses microorganisms to ferment the carbon source. During operation, microorganisms inside the reactor body 1 anaerobicly ferment the grain by-products to produce biogas, biogas slurry, and biogas residue. The biogas is discharged through a fixed exhaust pipe 17 at the top of the reactor body 1. When it is necessary to discharge biogas slurry and biogas residue, the receiving box 2 is processed first. Pushing the receiving box 2 causes several symmetrically distributed rollers 7 at its bottom to move into the limiting grooves 14 on both sides of the top of the bottom plate 6. The chamfers 16 on the front sides of the inner wall of the limiting grooves 14 facilitate the entry of the rollers 7. Simultaneously, the front of the receiving box 2... The handle 4 on the side makes it easier to push the receiving box 2. Then, the limiting mechanism 3 is operated to insert the limiting pin 303 into the insertion hole 302 inside the limiting frame 301, and to extend the limiting pin 303 into the limiting holes 15 on both sides of the base plate 6, thereby limiting the receiving box 2. At this time, the magnetic block 9 fixedly connected to the surface of the limiting pin 303 is magnetically attracted to the surface of the limiting frame 301, limiting the limiting pin 303 and preventing it from coming out of the limiting hole 15. The pull ring 10 facilitates the operation of the limiting pin 303. At this time, the discharge pipe 19 is located inside the fixing ring 502 in the blocking mechanism 5. The support 501 is fixed to the inner wall of the receiving box 2, and the rubber tube 503 fixedly connected to the fixing ring 502 is also in the corresponding position. Then, the discharge pipe 19 on the front side of the reactor body 1 is opened, and the biogas slurry and biogas residue are discharged into the rubber tube 503 through the discharge pipe 19. The flexibility of the rubber tube 503 guides the biogas slurry and biogas residue to avoid splashing. When the biogas slurry and biogas residue enter the receiving box 2, they will apply pressure to the baffle 8 that is movably inserted between the limiting frame 12 fixedly connected to the front and rear sides of the inner wall of the receiving box 2, so that the rear side of the baffle 8 and the front side of the silicone sealing gasket 13 fixedly connected to the front side of the rear limiting frame 12 are more secure. The tighter contact enhances the sealing performance, while the handles 11 on both sides of the top of the baffle 8 facilitate pulling the baffle 8 out between the two limiting frames 12, allowing the slurry and residue inside the receiving box 2 to be discharged. This solves the problem that some existing reactors for continuous anaerobic fermentation of grain by-products do not have a splash-proof structure at the discharge port. When the slurry and residue need to be received and transferred over long distances, splashing can easily occur during the discharge process, contaminating the operator's body and working environment. It should be noted that the reactor body 1 is based on existing and published mature technology, and its basic mechanism will not be elaborated here.
[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
