Description

Technical Field

[0001] The invention relates to the technical field of kitchen waste treatment, in particular to kitchen organic solid waste treatment equipment. Background Art

[0002] The kitchen organic solid waste treatment equipment is connected to special conditioning bacteria and auxiliary materials, and uses microbial fermentation to completely degrade the materials in a short time (such as 4 hours), achieving the effects of thorough fermentation, composting, sterilization and deodorization. At the same time, the equipment also pre-treats the garbage through physical means such as crushing, dehydration, separation, etc., to improve the efficiency and effect of biological treatment.

[0003] For example, the workbench and working machine for integrated processing of food waste fermentation and drying disclosed in publication number CN115532772B can realize the integrated utilization of resources by connecting with existing kitchen utensils during the entire food waste processing, so that the kitchen equipment and the integrated cabinet can be matched and installed, thereby improving the utilization rate of resources and the adaptability of the entire equipment for use in the kitchen. However, there are still some deficiencies in the fermentation processing of food waste with a high oil content: 1. Kitchen waste is often mixed with different amounts of oil. These oils come from the cooking oil used in the cooking process and the natural oils contained in the ingredients themselves, such as less oil in vegetables and relatively rich oil in meat. Oil has the characteristics of strong heat absorption and heat exchange capacity, resulting in different heat absorption capacity of kitchen waste with different oil contents during the fermentation process. Even the same type of kitchen waste will have different fermentation speeds due to different internal oil contents, thus forming the overall difference in the fermentation rate of kitchen waste in the fermentation barrel. When there are fast-fermenting and slow-fermenting kitchen waste in the fermentation barrel at the same time, if the fermentation conditions cannot be effectively adjusted and controlled to adapt to this difference, some of the garbage may have been processed while the other part is still in the early stage of fermentation, which not only wastes time and energy, but also may cause odor, bacteria breeding and other health problems due to long-term retention; 2. Proper stirring in the fermentation barrel (not continuous stirring) is one of the key links to ensure the smooth fermentation of food waste. However, the traditional stirring method often faces a significant problem when dealing with food waste containing a large amount of water and complex components: during stirring, the fermentation liquid will carry the food waste under the drive of the stirring rod to follow the stirring direction to form a vortex, causing the fermentation liquid and the food waste to rotate synchronously, while in fact the food waste and the fermentation liquid will remain in a relatively static state. Therefore, even if the agitator continues to work, the decomposition effect of the material is not ideal.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original kitchen organic solid waste treatment equipment. Summary of the invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. Specifically, the purpose of the present invention is to provide a kitchen organic solid waste treatment device to solve the problem that the fermentation speed will be significantly slowed down due to the difficulty of oil degradation, and even incomplete fermentation may occur. This uneven fermentation efficiency not only affects the overall efficiency of kitchen waste treatment, but also may affect the final drying effect and product quality because some waste cannot be fully fermented. In severe cases, it may even cause the performance of the entire treatment system to decline or malfunction.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a kitchen organic solid waste treatment device, comprising a fermentation barrel, a servo motor arranged on the top of the fermentation barrel, a fermentation liner placed in the fermentation barrel for storing fermented materials, and heating rings located between the fermentation barrel and the fermentation liner and arranged in a circular array in contact with the outer wall of the fermentation liner, and also comprising a driving rod that can negatively pressure suck the oil on the surface of the fermentation liquid, and a stacked stirring rod that is slidably sleeved on the driving rod and can be folded, the bottom of the driving rod is fixedly connected to a screw rod, and the screw rod is sleeved with an oil squeezing structure for lifting the stacked stirring rod to fold and squeeze the kitchen waste oil.

[0007] Preferably, the oil extrusion structure includes an extrusion net for pushing kitchen waste to squeeze the oil toward the inner wall of the fermentation tank, a lifting slider fixedly connected to the center of the extrusion net and sleeved on the screw rod to drive the extrusion net to rise and deform, the top of the lifting slider is fixedly connected to push rods distributed in a circular array, and the tops of the push rods are fixedly connected to rollers.

[0008] Preferably, first guide rods for limiting the lifting position of the lifting slider are arranged on both sides of the screw rod, and the bottom of the first guide rod is fixed to the bottom of the fermentation liner, a folding cavity is opened in the stacking stirring rod, and the top of the roller is in contact with the folding cavity at the bottom of the stacking stirring rod.

[0009] Preferably, the stacked stirring rod consists of two parts: a top fixed stirring rod and a plurality of foldable sliding stirring rods, and the inner wall of the sliding stirring rod is fixedly connected with a stacking slider, the outer wall of the stacking stirring rod is provided with a stacking groove for the stacking slider to slide, the inner wall of the stacking cavity of the fixed stirring rod is fixedly connected with a limiting slider, and the outer wall of the driving rod is provided with a lifting groove for the limiting slider to slide.

[0010] Preferably, a suction piston is slidably disposed inside the driving rod, and a pressure plate is fixedly connected to the top of the suction piston, and both ends of the pressure plate are exposed outside the driving rod and in contact with the top of the fixed stirring rod.

[0011] Preferably, the outer wall of the driving rod is provided with a movable groove for the pressure plate to slide, and a second guide rod for the pressure plate to slide is fixedly connected in the movable groove, and a spring is sleeved on the second guide rod.

[0012] Preferably, a drainage groove is fixedly connected inside the screw rod, and a liquid suction cavity for sucking oil is formed between the top of the drainage groove and the suction piston. A liquid inlet is opened at the bottom of the outer wall of the driving rod, and a one-way valve is provided in the liquid inlet and the drainage groove.

[0013] Preferably, a mesh frame is fixedly connected to the bottom edge of the extrusion net, and the mesh frame is connected to the inner wall of the fermentation liner, and a movable frame is provided on the inner side of the mesh frame, and the movable frame is connected to the top of the extrusion net so that the extrusion net can be deformed into a trapezoidal cylinder, and the top of the trapezoidal cylinder is arc-shaped so that kitchen waste can be moved to the outside of the extrusion net.

[0014] Preferably, a drain port for discharging oil is provided at the bottom of the screw rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Preheat the fermentation liner by heating the ring sheet, and then when the servo motor rotates forward, the stacked stirring rod rotates to make the lifting slider sleeved on the screw rod move from bottom to top through the guide setting of the first guide rod, and then the extrusion net connected to the lifting slider extends upward through the movable frame. Because the bottom edge of the extrusion net is provided with a net frame fixed to the inner wall of the fermentation liner, the extrusion net is deformed into a trapezoidal cylinder, and the top of the trapezoidal cylinder is arc-shaped, so that the process of deformation of the extrusion net pushes the kitchen waste to the outside of the extrusion net, and then after the extrusion net is deformed, its outer wall and the inner wall of the fermentation liner form an extrusion on the kitchen waste, thereby squeezing the kitchen waste, and then squeezing the oil inside it, and then squeezing it out, and the extruded oil floats on the fermentation liquid. At the top, at the same time, the stacked stirring rods in the jacking state, when in contact with the pressure plate, drive the suction piston to move upward from the driving rod, and make the pressure plate squeeze the spring sleeved on the second guide rod through the guide restriction of the second guide rod, because a suction cavity for sucking oil is formed between the top of the drainage groove and the suction piston, so that the suction piston sucks while the oil floating on the surface of the fermentation liquid is sucked into the suction cavity through the liquid inlet, and then the oil is guided by the drainage groove into the cavity inside the screw rod, and discharged from the discharge port at the bottom of the screw rod. In this process, the oil is evenly distributed in the fermentation liquid from the bottom to the top in the fermentation liner, so that the heat exchange efficiency of the oil is more evenly distributed in the fermentation liner, thereby improving the fermentation efficiency in the fermentation liner; 2. During the stirring process, when the roller contacts the folding cavity, due to its own rotatable characteristic, the stacked stirring rod will not be restricted in rotation while being pushed and folded. Subsequently, the squeezed kitchen waste is in a static state, while the stacked stirring rod that is in stirring work is in a dynamic stirring state, which solves the problem of unsatisfactory stirring effect caused by the relative static state of the two caused by the rotation of the kitchen waste and the fermentation liquid during stirring. This improves the extrusion efficiency of the oil in the kitchen waste and the mixing efficiency of the fermentation liquid and kitchen waste, and increases the efficiency of kitchen waste decomposition. The deformation and extrusion effect of the extrusion net not only pushes the kitchen waste to both sides, but also makes the extrusion deformation of the kitchen waste smaller and more delicate, which helps to fully contact the fermentation liquid with the kitchen waste, and further improves the fermentation efficiency.

The top of the lifting slider 6 is fixedly connected to a push rod 8 distributed in a circular array, and the top of the push rod 8 is fixedly connected to a roller 801.

[0031] First guide rods 11 for limiting the lifting position of the lifting slider 6 are arranged on both sides of the screw rod 5, and the bottom of the first guide rod 11 is fixed to the bottom of the fermentation liner 2, a folding cavity is opened in the stacking stirring rod 9, and the top of the roller 801 is in contact with the folding cavity at the bottom of the stacking stirring rod 9.

[0032] The stacking stirring rod 9 consists of two parts: a fixed stirring rod at the top and a plurality of foldable sliding stirring rods. The inner wall of the sliding stirring rod is fixedly connected with a stacking slider 17. The outer wall of the stacking stirring rod 9 is provided with a stacking slide groove 901 for the stacking slider 17 to slide. The inner wall of the stacking cavity of the fixed stirring rod is fixedly connected with a limiting slider 16, and the outer wall of the driving rod 4 is provided with a lifting slide groove 401 for the limiting slider 16 to slide.

[0033] A suction piston 1001 is slidably disposed in the driving rod 4 , and a pressure plate 10 is fixedly connected to the top of the suction piston 1001 . Both ends of the pressure plate 10 are exposed outside the driving rod 4 and contact the top of the fixed stirring rod.

[0034] The outer wall of the driving rod 4 is provided with a movable groove for the pressure plate 10 to slide, and a second guide rod 12 for guiding the pressure plate 10 to slide is fixedly connected in the movable groove, and a spring 13 is sleeved on the second guide rod 12.

[0035] A drainage groove 14 is fixedly connected inside the screw rod 5, and a suction cavity for sucking oil is formed between the top of the drainage groove 14 and the suction piston 1001. A liquid inlet 402 is opened at the bottom of the outer wall of the driving rod 4, and a one-way valve 15 is provided in the liquid inlet 402 and the drainage groove 14.

[0036] A mesh frame is fixedly connected to the bottom edge of the extrusion net 7, and the mesh frame is connected to the inner wall of the fermentation liner 2. A movable frame is arranged on the inner side of the mesh frame, and the movable frame is connected to the top of the extrusion net 7 so that the extrusion net 7 can be deformed into a trapezoidal cylinder, and the top of the trapezoidal cylinder is arc-shaped so that the kitchen waste can be moved to the outside of the extrusion net 7.

[0037] A drain port 501 for draining oil is provided at the bottom of the screw rod 5 .

[0038] Working principle: when using the kitchen organic solid waste treatment equipment, firstly, inject kitchen waste and fermentation liquid into the fermentation inner tank 2 respectively, and heat the heating ring sheet 3 to generate heat to generate heat in the fermentation inner tank 2 and pre-heat and ferment the kitchen waste, and then start the servo motor at a fixed time, and the pause interval of the servo motor is 30 minutes. When the servo motor rotates in the forward direction, the stacked stirring rod 9 rotates, and the lifting slider 6 sleeved on the screw rod 5 is moved from bottom to top by the lifting slider 6 through the guide setting of the first guide rod 11, and then the extrusion net 7 connected to the lifting slider 6 is extended upward through the movable frame, because the bottom edge of the extrusion net 7 is provided with a net frame fixed to the inner wall of the fermentation inner tank 2, the extrusion net 7 is deformed into a trapezoidal cylinder, and the top of the trapezoidal cylinder is arc-shaped, so that the deformation process of the extrusion net 7 pushes the kitchen waste to the outside of the extrusion net 7, and then the extrusion net 7 is deformed to make its outer wall The inner wall of the fermentation liner 2 forms an extrusion on the kitchen waste, thereby squeezing the oil in the kitchen waste, so that the oil inside is squeezed out, and the squeezed oil floats on the top of the fermentation liquid. At the same time, when the lifting slider 6 is lifting, the roller 801 fixed on the top rod 8 contacts the bottom folding cavity of the stacked stirring rod 9, and causes the stacked stirring rod 9 to be pushed upward, so that it is folded and lifted. When the roller 801 contacts the folding cavity, due to its own rotatable characteristics, the stacked stirring rod 9 is not restricted from rotating while being pushed and folded. Subsequently, the squeezed kitchen waste is in a static state, and the stacked stirring rod 9 in the stirring work forms a dynamic stirring state, so that the kitchen waste and the fermentation liquid no longer maintain a relatively static state, thereby improving the stirring efficiency of the squeezed oil and the fermentation liquid, and increasing the efficiency of kitchen waste decomposition; When the stacked stirring rod 9 in the jacking state contacts the pressure plate 10, the pressure plate 10 drives the suction piston 1001 to move upward from the driving rod 4, and the pressure plate 10 is guided by the second guide rod 12 to squeeze the spring 13 sleeved on the second guide rod 12. Because a suction cavity for sucking oil is formed between the top of the drainage groove 14 and the suction piston 1001, the suction piston 1001 sucks the oil floating on the surface of the fermentation liquid into the suction cavity through the liquid inlet 402, and then the drainage groove 14 guides the oil into the cavity inside the screw rod 5, and the oil is discharged from the discharge port 501 at the bottom of the screw rod 5, so that the oil is at the bottom of the fermentation liquid. Redistribute in the fermentation liquid, so that the heat exchange efficiency of the oil is more evenly distributed in the fermentation liquid, and the fermentation efficiency in the fermentation liquid is improved. Because the one-way valve 15 is provided in the liquid inlet 402, the liquid in the liquid suction cavity will not be discharged from the liquid inlet 402 again, and the one-way valve 15 is also provided in the drainage groove 14, so that the oil will not overflow the notch of the drainage groove 14 again. Then the servo motor rotates in the opposite direction, so that the driving rod 4 drives the screw rod 5 to rotate in the opposite direction, and the lifting slider 6 drives the extrusion net 7 to move downward. While moving, the stacked stirring rod 9 falls again, and the pressure plate 10 is reset to the original position through the resilience of the spring 13 as the stacked stirring rod 9 falls. Finally, the kitchen organic solid waste treatment device repeats the above-mentioned work on the kitchen waste in the fermentation tank 2 according to the timing setting of the servo motor, until the kitchen waste in the fermentation tank 2 is completely fermented and decomposed.
