Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to an organic waste feeding mechanism and a microbial fertilizer fermentation tank containing the mechanism. Background Technology

[0002] Organic waste is a type of waste material derived from plants and animals that can be degraded by microorganisms. Because it is rich in organic components, it can be transformed into resources such as fertilizer and biogas through biological treatment technologies such as composting and anaerobic digestion. Currently, microbial inoculant fermentation tanks are commonly used to treat organic waste. These tanks can create a controllable and optimized environment for microorganisms to decompose organic matter, while solving problems such as unstable environmental conditions, incomplete degradation, foul odor, pathogen residues, and long processing time that occur during natural fermentation.

[0003] In existing microbial fertilizer fermentation tanks, materials are typically fed into the tank via a screw conveyor. To prevent blockages, avoid cross-contamination, control hygiene risks, and extend equipment lifespan, the screw conveyor needs regular cleaning. However, due to the presence of hard-to-clean corners on the screw conveyor, simple rinsing is insufficient. If the screw conveyor is not disassembled and cleaned, residual impurities will rapidly decompose at suitable temperatures, producing corrosive substances or harmful bacteria, increasing the risk of contamination within the fermentation tank and affecting the quality of the microbial fertilizer fermentation. Furthermore, to ensure the airtightness between the screw conveyor's discharge port and the fermentation tank's inlet, the connection position needs to be calibrated multiple times during disassembly and assembly, resulting in inefficient maintenance of the screw conveyor. Therefore, this paper proposes an organic waste feeding mechanism and a microbial fertilizer fermentation tank containing such a mechanism, which eliminates the drawbacks of existing devices.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-6 As shown, a microbial fertilizer fermentation tank includes a screw conveyor body 6, a feed hopper 7 fixedly connected to the outer wall of the screw conveyor body 6, a feed inlet on the screw conveyor body 6 located inside the feed hopper 7, a discharge pipe 4 fixedly connected to the outer wall of the screw conveyor body 6, the discharge pipe 4 located above one side of the feed hopper 7, a docking ring 9 fixedly connected to the bottom end of the discharge pipe 4, the bottom outer wall of the docking ring 9 being frustoconical, a support frame 8 fixedly connected to the bottom end of the feed hopper 7, and a lifting mechanism for driving the feed hopper 7 to move up and down on the support frame 8; The lifting mechanism includes two support plates 2011 that are symmetrically fixedly connected to the inner wall of the support frame 8. Both support plates 2011 are located below the feed hopper 7, and two universal wheels 2013 are symmetrically arranged at the bottom of each of the two support plates 2011. It also includes a fermentation tank body 1, which is located on one side of the screw conveyor body 6. A fixing frame 3 is installed on the outer wall of the fermentation tank body 1. The fixing frame 3 is fixedly connected to the limiting baffle 202. A feed pipe 5 is fixedly connected to the top of the fermentation tank body 1. A docking sleeve 10 is fixedly connected to the top of the feed pipe 5. The docking sleeve 10 is slidably sleeved on the outer wall of the docking ring 9. A sealing ring is fixedly connected to the outer wall of the docking ring 9. The sealing ring is tightly fitted to the inner wall of the docking sleeve 10. In this embodiment, when in use, the material is put into the inside of the feed hopper 7. At this time, the material can be guided into the inside of the screw conveyor body 6 through the feed port. At the same time, through the cooperation of the screw conveyor body 6, the discharge pipe 4, the docking ring 9, the docking sleeve 10 and the feed pipe 5, the material can be put into the inner cavity of the fermentation tank body 1, so as to facilitate the transportation of the material. When it is necessary to clean the interior of the screw conveyor body 6 and the feed hopper 7, the support frame 8 can be separated from the ground by the lifting mechanism. At the same time, the feed hopper 7 is pushed by the support frame 8 and the screw conveyor body 6 drives the discharge pipe 4 to rise synchronously. At this time, the docking ring 9 is driven by the discharge pipe 4 and drives the sealing ring to move along the inner wall of the docking sleeve 10 until the docking ring 9 and the docking sleeve 10 are completely separated. This allows the discharge pipe 4 and the feed pipe 5 to be easily separated. Afterwards, the feed hopper 7 can be moved by the casters 2013, so that the screw conveyor body 6 can be moved to the designated position for disassembly and cleaning, effectively avoiding the presence of impurities in the dead corners inside the screw conveyor body 6 and the feed hopper 7. Then, the above operations are reversed to facilitate the installation and fixing of the screw conveyor body 6, thereby further improving the maintenance efficiency of the screw conveyor body 6. In one embodiment, such as Figures 1-5 As shown, the lifting mechanism also includes a docking assembly disposed on the feed hopper 7; The docking assembly includes: a lifting sleeve plate 203 fixedly connected to one side of the feed hopper 7, a connecting base plate 2015 provided on the lower surface of the lifting sleeve plate 203, a limit baffle 202 fixedly connected to the side of the connecting base plate 2015 away from the feed hopper 7, a locking bolt 204 provided at the top of the lifting sleeve plate 203, the locking bolt 204 passing through the lifting sleeve plate 203 to the outside of the bottom end of the connecting base plate 2015, and the locking bolt 204 being threadedly connected to the connecting base plate 2015; A limit component is installed on the connecting base plate 2015; A lifting assembly is installed on the support plate 2011; The limiting assembly includes two limiting blocks 201 symmetrically fixedly connected to the top of the connecting base plate 2015. The outer walls of the top of the two limiting blocks 201 are both frustum-shaped. The lifting sleeve 203 is slidably sleeved on the outer walls of the two limiting blocks 201. The locking bolt 204 is located between the two limiting blocks 201. Multiple balls are rotatably connected to one side of the lifting sleeve 203 at equal intervals. The multiple balls are in contact with the outer wall of the limiting baffle 202. Through the cooperation of the docking assembly and the limiting assembly, the fixed frame 3 and the feed hopper 7 can be conveniently docked and locked. In one embodiment, such as Figures 1-6 As shown, the lifting assembly includes: a lead screw 205 disposed at the top of the support plate 2011, a fixed bracket 206 rotatably connected to the top of the lead screw 205, the fixed bracket 206 being L-shaped, the fixed bracket 206 being fixedly connected to the support frame 8, and a lifting push plate 2012 sleeved on the outer wall of the lead screw 205, the lifting push plate 2012 being threadedly connected to the lead screw 205; The lifting push plate 2012 is equipped with a connecting component; The support frame 8 is equipped with a first transmission assembly; The connecting components include: two connecting push rods 2014 symmetrically fixedly connected to the bottom end of the lifting push plate 2012, a lead screw 205 located between the two connecting push rods 2014, the two connecting push rods 2014 being fixedly connected to two universal wheels 2013 respectively, and a support plate 2011 slidably sleeved on the outer wall of the two connecting push rods 2014. The first transmission component includes: a transmission rod 209 rotatably connected inside the support frame 8, a servo motor 207 installed at one end of the support frame 8, and the transmission rod 209 being driven by the output end of the servo motor 207; A second transmission assembly is provided on the transmission rod 209; The second transmission assembly includes two bevel gear rings 208 symmetrically fixedly connected to the outer wall of the transmission rod 209. The two bevel gear rings 208 are respectively located below the two support plates 2011. The outer walls of the two bevel gear rings 208 are meshed with bevel gears 2010. The bevel gears 2010 are fixedly connected to the end shaft of the lead screw 205. Through the mutual cooperation of the lifting assembly, the connecting assembly, the first transmission assembly and the second transmission assembly, the support frame 8 can be pushed to make the feed hopper 7 and the screw elevator body 6 lift as a whole.

[0023] The above embodiments disclose an organic waste feeding mechanism and a microbial fertilizer fermentation tank containing the mechanism. In use, the material is put into the inside of the feeding hopper 7. At this time, the material can be guided into the inside of the screw conveyor body 6 through the feeding port. At the same time, the screw conveyor body 6 can be started to stably lift the material. When the material moves to the port of the discharge pipe 4 under the drive of the screw conveyor body 6, the material enters the inner cavity of the fermentation tank body 1 along the discharge pipe 4, the docking ring 9, the docking sleeve 10 and the inner wall of the feeding pipe 5 under the action of gravity, thereby facilitating the transportation of the material. When cleaning is required inside the screw conveyor body 6 and the feed hopper 7, the locking bolt 204 can be turned with a tool to release the fixing lock between the lifting sleeve 203 and the connecting base plate 2015. Then, the servo motor 207 is started to drive the transmission rod 209 to rotate. At this time, the bevel gear ring 208, driven by the transmission rod 209, drives the bevel gear 2010 to rotate through its core. Simultaneously, the lead screw 205, driven by the bevel gear 2010, drives the lifting push plate 2012 to descend through its thread. At this time, the two connecting push rods 2014, pushed by the lifting push plate 2012, move along the support... The inner wall of the support plate 2011 slides and pushes the caster 2013 to descend synchronously. When the caster 2013 contacts the ground, the support frame 8 can be separated from the ground by the push of the screw 205 through the fixed bracket 206. At the same time, the feed hopper 7 is pushed by the support frame 8 and drives the discharge pipe 4 to rise synchronously through the screw elevator body 6. At this time, the docking ring 9 is driven by the discharge pipe 4 and drives the sealing ring to move along the inner wall of the docking sleeve 10 until the docking ring 9 and the docking sleeve 10 are completely separated. This allows the discharge pipe 4 and the feed pipe 5 to be easily separated. During this process, the lifting sleeve 203, driven by the feeding hopper 7, slides along the outer wall of the limiting baffle 202 via ball bearings and moves along the outer wall of the limiting insert 201 until the lifting push plate 2012 contacts the upper surface of the support plate 2011. At this point, the lifting sleeve 203 and the limiting insert 201 separate. Then, the feeding hopper 7 can be moved by the caster wheel 2013, thereby moving the screw conveyor body 6 to a designated position for disassembly and cleaning. This effectively avoids impurities remaining in the dead corners inside the screw conveyor body 6 and the feeding hopper 7. Afterward, the above operation is reversed, and the screw conveyor body 6 can be conveniently installed and fixed, thereby further improving the maintenance efficiency of the screw conveyor body 6.

[0024] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
