Description

Technical Field

[0001] The present invention relates to the technical field of microbial decomposition processing machines, and in particular to a waste food microbial decomposition processing machine. Background Art

[0002] The food waste microbial decomposition processor is an environmentally friendly device that integrates crushing, mixing, and microbial decomposition technologies. Its built-in high-intensity crushing system performs multi-stage shearing and crushing on various types of food waste, converting large organic matter into small particles, significantly improving the efficiency of subsequent microbial decomposition. After entering the fermentation chamber, the crushed material is stirred in a three-dimensional motion by a variable frequency agitator, ensuring full contact with the thermophilic aerobic bacteria. This ensures rapid waste degradation, ultimately transforming it into an odorless, sterile powdered organic fertilizer, achieving waste resource utilization.

[0003] The patent document with Chinese patent publication number CN117798164A discloses a kitchen waste treatment device based on biodegradation. The device includes a filtering mechanism, a stirring mechanism, a crushing mechanism and a fermentation mechanism. The filtering mechanism is connected to the crushing mechanism and the stirring mechanism. The fermentation mechanism is arranged in the crushing mechanism and the stirring mechanism. Large-volume garbage and small-volume garbage can be separated by the filtering mechanism. Subsequently, the large-volume garbage is crushed by the crushing mechanism, and the small-volume garbage is stirred or partially crushed by the stirring mechanism. At the same time, the fermentation mechanism performs a fermentation step on the kitchen waste, which effectively improves the garbage degradation treatment and improves the kitchen waste treatment efficiency by reducing the odor of the garbage.

[0004] The food waste treatment equipment described in the aforementioned patent document processes material by adding it to a crushing mechanism through a feed inlet. The crushing mechanism then breaks the material into small particles, and then conveys the crushed material to a stirring mechanism for mixing. However, when the material is added to the crushing mechanism, it accumulates inside the crushing mechanism. When the material accumulates too much, the crushing roller within the crushing mechanism overloads, causing mechanical failure of the crushing roller. Therefore, a food waste microbial decomposition processor is proposed. Summary of the Invention

[0005] The purpose of the present invention is to remedy the shortcomings of the existing technology and propose a food waste microbial decomposition processing machine. The displacement of the movable plate pushes the positioning frame, so that the movable frame drives the push rod to move axially, and one end of the push rod slides along the second clearance groove and drives the transmission rod to rotate around the hinge point of the support rod. The end of the transmission rod away from the support rod drives the baffle plate downward through the third clearance groove. Thereby, the baffle plate can effectively reduce the flow cross-sectional area of ​​the feed pipe. Adaptive adjustment of the feed flow rate is achieved. By dynamically matching the material accumulation amount and the opening of the baffle plate, the problem of mechanical failure of the crushing roller due to overload operation is effectively avoided, thereby ensuring the stable operation of the crushing roller in the optimal load range.

As a result, the baffle plate can effectively reduce the flow cross-sectional area of ​​the feed pipe, achieving adaptive adjustment of the feed flow rate. By dynamically matching the material accumulation amount with the opening of the baffle plate, the problem of mechanical failure of the crushing roller due to overload operation is effectively avoided, thereby ensuring the stable operation of the crushing roller in the optimal load range.

[0032] Second, the present invention shortens the overall length of the oil pipe, reducing the distance the oil travels inside the pipe. This effectively solves the problem of excessively long oil pipes causing a large temperature difference between the portion near the input end and the portion near the output end, making it impossible to ensure uniform heating of the inner mixing tank.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] See also Figures 1 to 10 The present invention provides the following embodiments: a food waste microbial decomposition processing machine, comprising a stirring mechanism 1, a base 2 disposed at the bottom of the stirring mechanism 1, a heating mechanism 4 disposed on the base 2 for heating the stirring mechanism 1, and a crushing and feeding mechanism 3 disposed at the input end of the stirring mechanism 1, the crushing and feeding mechanism 3 comprising a crushing box 31 that can be fixedly connected to the input end of the stirring mechanism 1, and two sets of crushing rollers 312 that can rotate clockwise and counterclockwise are installed inside the crushing box 31;

[0053] A mounting groove 313 is provided on the inner side of the crushing feeding mechanism 3 near the crushing roller 312, and a limiting slide rail 314 is fixed on the inner wall of the crushing box 31 at both ends of the mounting groove 313;

[0054] A movable plate 33 is installed inside the mounting groove 313. Both sides of the movable plate 33 are provided with limiting slide grooves 337 that can slide with the limiting slide rails 314. The side surfaces of the movable plate 33 are in sliding contact with the mounting groove 313 and the inner wall of the crushing box 31.

[0055] A movable frame 331 that can extend out of the crushing box 31 is fixed to one side of the movable plate 33, and a push rod 332 is fixed to the side of the movable frame 331 away from the movable plate 33.

[0056] A feeding pipe 32 is fixed to the top of the crushing box 31 and is in communication with the crushing box 31. A first clearance groove 321 is longitudinally defined on the top of the feeding pipe 32. A retaining plate 335 is mounted within the first clearance groove 321 and is movable longitudinally along the first clearance groove 321. The retaining plate 335 is sealed against the first clearance groove 321. A third clearance groove 336 for limiting position is defined on the top of the retaining plate 335.

[0057] Support rods 322 are symmetrically fixed on both sides of the feeding tube 32. A transmission rod 333 is hingedly provided at one end of the support rod 322 away from the feeding tube 32. A second clearance groove 334 is formed at the bottom end of the transmission rod 333. The top end of the push rod 332 is installed in the second clearance groove 334 and can slide along the second clearance groove 334.

[0058] The top end of the transmission rod 333 is installed in the third clearance groove 336 and can slide along the third clearance groove 336 .

[0059] The outer wall of the crushing box 31 is equipped with two sets of first motors 311, and the output end of each first motor 311 is coaxially fixedly connected to the extended end of the crushing roller 312. When the first motor 311 is started, the two sets of crushing rollers 312 respectively perform clockwise and counterclockwise differential rotational motions, and the materials are sheared and crushed through the meshing action of the crushing rollers 312. During the crushing operation, when the material accumulation height in the crushing box 31 reaches a preset threshold, the axial thrust exerted by the accumulated material on the movable plate 33 drives the movable plate 33 to form a guided sliding fit with the limiting slide 337 and the limiting slide rail 314, so that the distance between the working surface of the movable plate 33 and the inner wall of the crushing box 31 is gradually reduced. During the displacement of the movable plate 33, the push rod 332 is driven axially by the movable frame 331. The end of the push rod 332 away from the movable frame 331 slides along the second clearance groove 334 and drives the transmission rod 333 to rotate around the hinge point of the support rod 322. At this point, the end of the transmission rod 333 away from the support rod 322 slides along the third clearance groove 336, driving the material baffle 335 downward along the first clearance groove 321. This effectively reduces the flow cross-sectional area of ​​the feed pipe 32, enabling adaptive regulation of the feed flow rate. By dynamically matching the material accumulation level with the opening of the material baffle 335, mechanical failure of the crushing roller 312 caused by overload is effectively avoided, thereby ensuring stable operation of the crushing roller 312 within the optimal load range.

[0060] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The second limiting frames 34 are symmetrically fixed on both sides of the crushing box 31 near the top. The top of the second limiting frame 34 is provided with a limiting hole 341 for the push rod 332 to be inserted. The push rod 332 slides in cooperation with the limiting hole 341.

[0061] To ensure the stability of the push rod 332, second limiting brackets 34 are fixed to both sides near the top of the crushing box 31. A limiting hole 341 is formed at the top of the second limiting bracket 34 to accommodate the push rod 332. When the push rod 332 moves, it can move along the central axis of the limiting hole 341. This not only ensures the stability of the push rod 332 during movement, but also effectively prevents the push rod 332 from bending due to overload.

[0062] Please refer to Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10 A first spring 35 for pushing the movable frame 331 to return to its original position is provided on the inner side of the second limiting frame 34 , and the first spring 35 is sleeved on the push rod 332 ;

[0063] A baffle 342 is fixed on the inner side of the second limiting frame 34 to prevent the moving frame 331 from continuing to move downward.

[0064] When the movable plate 33 pushes the movable frame 331, the movable frame 331 squeezes the first spring 35 outside the push rod 332, causing the first spring 35 to gradually accumulate potential energy. When the squeezing force on the movable plate 33 disappears or gradually weakens, the squeezing force of the movable frame 331 on the first spring 35 simultaneously weakens or disappears. At this time, the potential energy accumulated by the first spring 35 is released, causing the first spring 35 to push the movable frame 331 to return to its initial position. In order to prevent the movable plate 33 from falling off from the mounting groove 313, a baffle 342 is fixed on the inner side of the second limiting frame 34. When the lower end surface of the top of the movable frame 331 contacts the baffle 342, the movement of the movable frame 331 stops, effectively preventing the movable plate 33 from falling off from the mounting groove 313.

[0065] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The stirring mechanism 1 includes a rotatable inner stirring barrel 11, and a toothed belt 113 is provided on the outer wall of the inner stirring barrel 11;

[0066] A second motor 5 is fixed to the top of the base 2 , and a driving gear 51 that can mesh with the toothed belt 113 is fixed to the output end of the second motor 5 .

[0067] To ensure efficient rotation of the inner mixing drum 11, a toothed belt 113 is installed on the outer wall of the inner mixing drum 11 around its central axis. When the second motor 5 is activated, it drives the driving gear 51 at the output end to rotate. This rotation of the driving gear 51 simultaneously drives the inner mixing drum 11 around its central axis via the meshing toothed belt 113, thus ensuring efficient rotation of the inner mixing drum 11.

[0068] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 The stirring mechanism 1 further includes a heat-insulating outer shell 14 sleeved on the inner stirring barrel 11, and the bottom of the heat-insulating outer shell 14 is fixed to the top of the base 2;

[0069] A plurality of annular grooves 141 are provided on the inner wall of the heat-insulating shell 14;

[0070] A plurality of annular slide rails 111 that correspond one-to-one with the annular slide grooves 141 are fixed to the outer wall of the inner mixing barrel 11, and the annular slide rails 111 and the annular slide grooves 141 are slidably matched.

[0071] To ensure stable operation of the inner mixing drum 11, multiple annular rails 111 are evenly distributed on the outer wall of the inner mixing drum 11, which are capable of slidingly engaging with the annular grooves 141. As the inner mixing drum 11 rotates, the inner mixing drum 111 drives the annular rails 111 to slide along the annular grooves 141. This prevents deviation of the inner mixing drum 11 during rotation and effectively ensures its stability.

[0072] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A first cover head 12 is provided at one end of the inner mixing barrel 11, and a discharge port 121 for discharging the material is provided at the bottom of the first cover head 12;

[0073] The other end of the inner mixing barrel 11 is provided with a second cover head 13. The first cover head 12 and the second cover head 13 are respectively fixed to the ends of the heat-insulating outer shell 14. The first cover head 12 and the second cover head 13 are respectively movably connected to the inner mixing barrel 11.

[0074] A spiral stirring blade 112 is fixed on the inner wall of the inner stirring barrel 11;

[0075] A rotatable spiral stirring shaft 6 is horizontally arranged inside the inner stirring barrel 11;

[0076] A third motor 61 capable of driving the spiral stirring shaft 6 to rotate is fixed to one side of the first cover head 12, and the output end of the third motor 61 is fixedly connected to one end of the spiral stirring shaft 6.

[0077] As the inner mixing barrel 11 rotates, the spiral stirring blades 112 fixed to the inner wall of the inner mixing barrel 11 rotate synchronously. The contact between the blades of the spiral stirring blades 112 and the material generates axial thrust, causing the spiral stirring blades 112 to drive the material along the axis of the inner mixing barrel 11 toward the second shroud 13, forming a directional flow. Simultaneously, the third motor 61, through a transmission mechanism, drives the spiral stirring shaft 6 in counter-rotational motion. The blades of the spiral stirring shaft 6 produce an axial conveying effect opposite to the flow direction of the spiral stirring blades 112. This creates a bidirectional flow coupling effect within the inner mixing barrel 11: the spiral stirring blades 112 on the inner wall of the inner mixing barrel 11 dominate the radial-to-axial composite flow, while the spiral stirring shaft 6 creates an axial reverse compensation flow field. These two flow modes form a three-dimensional turbulent flow field within the mixing chamber. Through the synergistic effect of the flow fields, the material undergoes intense shear mixing at the intersection of the forward and reverse flows, achieving a uniform distribution of the material's microscopic components and improving mixing efficiency.

[0078] Please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 9The heating mechanism 4 includes a plurality of oil pipes 42 equidistantly arranged outside the inner mixing barrel 11 , and the oil pipes 42 are spirally wound on the outer wall of the inner mixing barrel 11 ;

[0079] The heating mechanism 4 further includes an intelligent heating oil storage tank 43 fixed inside the base 2 for heating the oil, and the output end of the oil pipe 42 can be connected to the interior of the intelligent heating oil storage tank 43;

[0080] An oil pump 41 capable of extracting the oil from the intelligent heating oil storage tank 43 is also fixed on the base 2. The input end of the oil pump 41 can be connected to the interior of the intelligent heating oil storage tank 43, and the output end of the oil pump 41 is respectively connected to the input end of the oil pipe 42.

[0081] By winding multiple groups of oil pipes 42 at equal intervals on the outside of the inner stirring barrel 11, the overall length of the oil pipe 42 is shortened. When the oil pump 41 is started, the oil pump 41 can extract the heated oil in the intelligent heating oil storage tank 43, and then the oil pump 41 transports the extracted oil to the inside of the oil pipe 42 through the output end. This shortens the distance the oil travels inside the oil pipe 42, effectively solving the problem of the oil pipe 42 being too long, resulting in a large temperature difference between the part of the oil pipe 42 close to the input end and the part close to the output end. As a result, it is impossible to ensure that the inner stirring barrel 11 is heated evenly. Moreover, the shortening of the overall distance of the oil pipe 42 can ensure that when the oil flows back from the oil pipe 42 to the intelligent heating oil storage tank 43, it can maintain a certain temperature, reduce the rapid loss of heat, and thus reduce the energy consumption of the intelligent heating oil storage tank 43 when heating the oil.

[0082] Please refer to Figure 3 A first limiting frame 131 is fixed inside the second cover head 13 to limit the end of the spiral stirring shaft 6 away from the first cover head 12. The end of the spiral stirring shaft 6 away from the first cover head 12 is rotatably connected to the first limiting frame 131.

[0083] To ensure the stability of the agitator shaft 6, a first retaining bracket 131 is secured within the second housing 13. The end of the agitator shaft 6 facing away from the first housing 12 is then mounted on the retaining bracket 131. When the third motor 61 rotates the agitator shaft 6, the end away from the first housing 12 rotates around the central axis of the first retaining bracket 131. This effectively prevents vibration of the agitator shaft 6 during rotation, thereby ensuring its stability.

[0084] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
