Description

Technical Field

[0001] This utility model relates to the field of fermentation devices, and in particular to a layered stacked pig manure fermentation reaction device. Background Technology

[0002] In large-scale farms, pig manure treatment has always faced the dual challenges of fermentation efficiency and space utilization. In existing technologies, traditional fermentation devices generally adopt a single-layer flat-lay fermentation process. When the height of the pig manure pile exceeds 3 meters, the porosity of the lower layer material decreases due to the static pressure (about 50-80 kPa) from the upper layer, resulting in an anaerobic environment and causing abnormal local temperature increases (up to 65°C or higher). This not only inhibits microbial activity but also produces ammonia gas that pollutes the environment.

[0003] Currently, traditional fermentation chambers use fixed base plates. The weight of the pile causes excessively high pressure density in the lower layers, exceeding the suitable bearing capacity of microorganisms, resulting in unsatisfactory fermentation effects and significant differences in the degree of fermentation between the upper and lower layers of pig manure. Therefore, this solution proposes a layered stacked pig manure fermentation reactor. Utility Model Content

[0004] This invention proposes a layered stacked pig manure fermentation reactor, which solves the problem in the prior art where excessively high stacking of pig manure during fermentation leads to excessive pressure and excessively high temperature on the lower layer of manure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A layered stacked pig manure fermentation reactor includes multiple stacking mechanisms stacked sequentially from top to bottom and a receiving hopper installed at the bottom of the lowest stacking mechanism.

[0007] The stacking mechanism includes a mounting plate and a fixing frame fixed to the top surface of the mounting plate. The bottom surface of the mounting plate is provided with a dropping trough for the feces to fall. Multiple trays for receiving feces are rotatably connected to the inside of the dropping trough. A drive assembly for driving the trays to flip and discharge the feces on the top surface of the mounting plate downwards is installed on the outside of the mounting plate.

[0008] The receiving hopper includes a bottom plate and a second fixing frame fixed to the top surface of the bottom plate, and the top of the second fixing frame is fixedly connected to the bottom surface of the mounting plate in the bottom stacking mechanism.

[0009] It also includes a material turning mechanism, which includes a stirring shaft rotatably connected to the inner side of a fixed frame and a transmission assembly installed on the outer side of the fixed frame for driving the stirring shaft to rotate and reciprocating along its axial direction when rotating.

[0010] As a further improvement to the above solution, the fixed frame has an open structure on one side, and a baffle for sealing the open side is hinged to the fixed frame via a hinge. The end of the baffle away from the hinge is locked to the fixed frame via a latch.

[0011] As a further improvement to the above solution, both long sides of the pallet extend along the width of the plate and form a convex ridge with an isosceles triangle in longitudinal section.

[0012] As a further improvement to the above solution, both ends of the pallet are rotatably connected to the side wall of the material discharge chute via rotating shafts. One end of each of the two rotating shafts extends to the outside of the mounting plate and is fixed with a transmission gear. The drive assembly is provided in two sets, and the two sets of drive assemblies are respectively installed on the two long sides of the mounting plate. The drive assembly includes a telescopic component fixed to the long side of the mounting plate and a rack fixed to the output end of the telescopic component and meshing with multiple transmission gears.

[0013] As a further improvement to the above solution, one side of the fixed frame is provided with an outlet for discharging feces, and the top surface of the bottom plate is an inclined surface that slopes downward toward the outlet side.

[0014] As a further improvement to the above solution, the transmission assembly includes a mounting bracket fixed to an outer wall of a fixed frame and a connecting shaft rotatably connected to the mounting bracket. One end of the stirring shaft extends to the outer side of the fixed frame, and a connecting hole coaxially arranged with the outer end of the stirring shaft located on the outer side of the fixed frame is provided. Multiple limiting grooves arranged along the length direction are provided on the inner wall of the connecting hole. One end of the connecting shaft extends into the connecting hole and is slidably connected with it. Multiple limiting posts corresponding to the limiting grooves are fixed on the outer periphery of the connecting shaft. One end of the limiting post extends into the limiting groove and is slidably connected with it. The transmission assembly also includes a guide member installed on the outer periphery of the fixed frame for driving the stirring shaft to reciprocate along its own axial direction when it rotates.

[0015] As a further improvement to the above solution, the guide component includes a guide cylinder fixed to the outer wall of the fixed frame, and the guide cylinder is movably sleeved on the outside of the stirring shaft. The inner circle of the guide cylinder is provided with an annular guide groove that is coaxial with and inclined to it. The guide component also includes a guide post fixed to the outer periphery of the stirring shaft, one end of which extends into the guide groove and slides with it.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By stacking multiple stacking structures, not only can the space occupancy be reduced, but the problem of excessive pressure and excessively high fermentation temperature on the lower layer of pig manure due to excessively high stacking of pig manure can also be avoided, thus ensuring the balanced fermentation of pig manure.

[0018] 2. Through the cooperation between the pallet and the drive assembly, the pallet can be driven to flip when the manure in the stacking mechanism is discharged, so that the manure on the top surface of the mounting plate can fall through the gap between the pallets. At the same time, when stacking pig manure into the stacking mechanism, the pallets in the stacking mechanism of the stacking layer can be closed, and all the push plates in the multiple stacking mechanisms above the stacking mechanism can be flipped open, so that the pig manure can enter from the top stacking mechanism and finally fall into the stacking layer.

[0019] 3. Through the cooperation between the stirring shaft and the transmission assembly, the stirring shaft can be driven to rotate while moving back and forth along its axial direction, which can facilitate a more thorough turning of the manure in the stacking mechanism.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] Example 1:

[0034] Please combine Figures 1-7 This embodiment of a layered stacked pig manure fermentation reactor includes multiple stacking mechanisms 1 stacked sequentially from top to bottom and a receiving hopper 4 installed at the bottom of the stacking mechanism 1. The stacking of multiple stacking mechanisms can effectively prevent the upper layer of manure from squeezing the lower layer of manure when the amount of manure is too large, and also prevent the temperature of the lower layer of manure from being too high, which would affect the fermentation effect.

[0035] The stacking mechanism 1 includes a mounting plate 101 and a fixing frame 102 fixed to the top surface of the mounting plate 101. A discharge trough 103 for dropping manure is provided on the bottom surface of the mounting plate 101. Multiple trays 6 for receiving manure are rotatably connected to the inner side of the discharge trough 103. A drive assembly for driving the trays 6 to flip and discharge manure from the top surface of the mounting plate 101 downwards is installed on the outer side of the mounting plate 101. Both ends of the trays 6 are rotatably connected to the side wall of the discharge trough 103 via rotating shafts. One end of each rotating shaft extends to the outer side of the mounting plate 101 and is fixed with a transmission gear 8. Two sets of drive assemblies are provided, and the two sets of drive assemblies are respectively installed on the two long sides of the mounting plate 101. Each drive assembly includes a telescopic member 7 fixed to the long side of the mounting plate 101 and a fixed... A rack 9 is fixed at the output end of the telescopic component 7 and meshes with multiple transmission gears 8. The telescopic component 7 is either an electric telescopic rod or an electric push rod. When multiple pallets 6 are closed, the discharge chute 103 is blocked by the pallets 6, so that the feces can be retained inside the stacking mechanism 1. When the feces in the stacking mechanism need to be discharged, the telescopic component 7 is activated to extend, thereby driving the rack 9 to move to the left. After the rack 9 moves, it drives the transmission gears 8 to rotate, which in turn drives the pallets 6 to flip. After the pallets 6 are flipped 90 degrees, the extension of the telescopic component 7 is stopped. The feces in the stacking mechanism 1 can then fall into the discharge chute 103 and enter the next layer of the stacking mechanism 1. When all the pallets 6 in the stacking mechanism 1 are flipped and opened, the feces will fall into the receiving hopper 4 and finally be discharged.

[0036] The receiving hopper 4 includes a bottom plate 401 and a fixing frame 402 fixed to the top surface of the bottom plate 401. The top of the fixing frame 402 is fixed to the bottom surface of the mounting plate 101 in the bottom stacking mechanism 1. The fixing frame 402 has an outlet for discharging feces on one side. The top surface of the bottom plate 401 is a sloped surface that slopes downward toward the outlet side. The sloped surface of the top surface of the bottom plate 401 is convenient. The feces falling into the receiving hopper 4 are discharged from the outlet of the fixing frame 402.

[0037] In this embodiment, the fixed frame 102 has an open structure on one side, and a baffle 2 for sealing the open is hinged to the fixed frame 1 on this side by a hinge. The end of the baffle 2 away from the hinge is locked to the fixed frame 1 by a latch. The open structure on one side of the fixed frame 102 can open the baffle 2 when the manure in the stacking mechanism 1 is discharged, so that the manure in the stacking mechanism 1 can be discharged from the open structure.

[0038] In this embodiment, both long sides of the tray 6 extend along the width of the plate and form a convex ridge with an isosceles triangle in longitudinal section. The structure of the convex ridge can effectively prevent the feces from falling after the tray 6 is flipped. At the same time, it can also prevent the two adjacent trays 6 from touching each other when flipped due to excessive thickness of the tray 6.

[0039] Example 2:

[0040] Combination Figures 1-2 and Figures 4-7 This embodiment, based on embodiment 1, further improves upon the following: it also includes a material-turning mechanism. The material-turning mechanism includes a stirring shaft 5 rotatably connected to the inner side of the fixed frame 102 and a transmission assembly 3 installed on the outer side of the fixed frame 102 for driving the stirring shaft 5 to rotate and reciprocating along its axial direction during rotation. Multiple stirring rods are fixed to the outer periphery of the stirring shaft 5. The transmission assembly 3 includes a mounting bracket 301 fixed to the outer wall of the fixed frame 102 and a connecting shaft 305 rotatably connected to the mounting bracket 301. One end of the stirring shaft 5 extends to the outer side of the fixed frame 102, and a connecting hole 11 coaxially arranged at the outer end of the stirring shaft 5 located on the outer side of the fixed frame 102 is provided. Multiple limiting grooves 12 arranged along the length direction are provided on the inner wall of the connecting hole 11. One end of the connecting shaft 305 extends into the connecting hole 11 and is slidably connected thereto. Multiple pairs of... The limiting post 307 is provided in the limiting groove 12. One end of the limiting post 307 extends into the limiting groove 12 and slides therein. According to the width of the fixing frame 102, multiple stirring shafts 5 can be set for turning over the material. Each stirring shaft 5 is provided with a corresponding transmission component 3. When multiple stirring shafts 5 are provided, the connecting shafts 305 in two adjacent transmission components 3 are connected by a belt 303. The connecting shaft 305 is provided with a pulley for connecting the belt 303. The mounting frame 301 is equipped with a motor 302, and one end of the output end of the motor 302 is connected to one of the connecting shafts 305. After the motor 302 rotates, it drives the connecting shaft 305 connected to it to rotate. When multiple stirring shafts 5 are provided, the connecting shaft 305 drives the other connecting shafts 305 to rotate, thereby driving multiple stirring shafts 5 to rotate, so as to turn over the manure in the stacking mechanism 1.

[0041] The transmission assembly 3 also includes a guide component installed on the outer periphery of the fixed frame 102 for driving the stirring shaft 5 to reciprocate along its own axial direction when it rotates. The guide component includes a guide cylinder 304 fixed to the outer wall of the fixed frame 102, and the guide cylinder 304 is movably sleeved on the outside of the stirring shaft 5. The inner ring of the guide cylinder 304 has an annular guide groove 306 that is coaxial with it and inclined. The guide component also includes a guide post 10 fixed on the outer periphery of the stirring shaft 5. One end of the guide post 10 extends into the guide groove 306 and slides with it. While the connecting shaft 305 drives the stirring shaft 5 to rotate, the guide cylinder 304 remains stationary. The guide post 10 on the outer periphery of the stirring shaft 5 slides along the inner side of the guide groove 306. Because the guide groove 306 is inclined, the guide post 10 will reciprocate along the axial direction of the guide cylinder 304 when it slides along the inner side of the guide groove 306, thereby driving the stirring shaft 5 to move synchronously. This allows the stirring shaft 5 to more thoroughly turn over and mix the manure inside the stacking mechanism 1.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
