Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical devices, and relates to a kitchen waste pretreatment device, specifically a community household kitchen waste centralized collection and timely full-volume pretreatment device connected with biomass utilization. Background Art

[0002] Garbage classification, recycling and treatment is a major strategic measure for the national economy and people's livelihood related to sustainable development. Domestic waste can generally be divided into four categories: recyclable waste, kitchen waste, hazardous waste and other waste. At present, there are a wide variety of intelligent recyclable waste classification and recycling bins (facilities) with functions such as weighing, crushing or compression, and point redemption in the market for recyclable waste. At the same time, most of these intelligent recyclable waste classification and recycling bins (facilities) as public welfare projects also have the function of hazardous waste recycling. It can be said that the recycling and treatment technology of recyclable and hazardous waste in domestic waste is relatively mature. However, due to the special characteristics of household kitchen waste, which is small in daily production per household but is produced every day and is extremely easy to rot, its recycling and treatment is difficult. Therefore, most communities do not have special facilities for kitchen waste recycling and treatment. Even if some communities have set up kitchen waste recycling bins, they mostly only provide "containers" for concentrated stacking of kitchen waste, such as the common flip-top plastic kitchen waste bins. As we all know, kitchen waste is perishable. If the piled kitchen waste is not handled in time, even if the trash can is covered, it will inevitably cause problems such as fly breeding, odor, and dirty water overflow. In order to solve this problem, some communities provide kitchen waste recycling bins with good sealing properties. However, due to the small amount of food waste generated per household and their dispersion, the kitchen waste recycling bins are frequently opened, resulting in the inability to ensure the sealing properties of the kitchen waste recycling bins. Moreover, more importantly, the volume of the common flip-top plastic kitchen waste bins and the well-sealed kitchen waste recycling bins set up in the community is not too large, so it is inevitable that the volume of the trash cans or recycling bins is insufficient, especially during holidays and other periods, which often makes it difficult to put the kitchen waste. It is precisely because of the above factors that at present, community residents often classify household kitchen waste as other garbage and dispose of it together. This not only prevents the kitchen waste, which accounts for a very high proportion of domestic waste (according to relevant statistics, kitchen waste accounts for as much as 50-60% of domestic waste), from being effectively utilized as a resource, but also greatly increases the amount and difficulty of disposal of other waste (kitchen waste has a high water content and is easily perishable. Mixing it with other waste will inevitably cause secondary pollution to other waste). It can be seen that the recycling and treatment of household kitchen waste is a difficult and painful point in the current classification and recycling of domestic waste.

[0003] The patent with application number 202210480799.3 discloses an intelligent kitchen waste treatment machine that can automatically weigh, break bags, collect garbage bags, roughly crush kitchen waste, separate solids and liquids, and separate oil and water. In this patent, part of the liquid in the garbage that has been crushed and crushed by the crushing mechanism first flows through the solid-liquid separation mechanism and enters the oil-liquid separation mechanism. After that, the crushed garbage enters the solid-liquid separation mechanism. The solid and liquid in the garbage are separated by the squeezing of the solid-liquid separation mechanism. The solid is collected and the liquid flows into the oil-liquid separation mechanism. The oil in the liquid is separated and collected through the operation of the oil-liquid separation mechanism. It can be seen that the core idea of ​​this patent is to separate and process the solids and oils in the kitchen waste for recycling, and the liquid with low recycling value is discharged as sewage. In fact, the liquid in the kitchen waste is also a recyclable material that can be recycled. Separating the liquid from the kitchen waste and discharging it as sewage not only reduces the resource utilization rate of the kitchen waste but also increases the amount of domestic sewage disposal. More importantly, the patented product cannot be effectively connected with the mainstream mode of biomass utilization and disposal of existing food waste (a general term for catering waste and kitchen waste). Considering the benefits and efficiency, at present, food waste biomass utilization enterprises centrally transfer food waste and then carry out diversified disposal in enterprises, rather than directly transfer the secondary products of solids and grease in food waste. In particular, the daily amount of household food waste generated by each household is small and scattered. Even for large-scale community food waste, the solids and grease obtained after removing the liquid are limited. Therefore, these secondary products are inevitably not processed in time and most companies are unwilling to process them every day, which makes the actual effect of the patented product often far below expectations. Its seemingly timely treatment not only fails to achieve the full resource utilization of food waste, but also increases the amount of sewage disposal and the problem of food waste being perishable and needing to be promptly removed has not been solved. In addition, if a certain number of such devices are put into each community, it is difficult to truly implement due to the disproportionate input and output.

[0004] For another example, the invention patent with application number 202010910910.9 is designed to address the current problems in the disposal of food waste, such as inadequate crushing and grinding of food waste and environmentally unfriendly use. It has a crushing bin, a grinding bin, a filter bin, a fermentation agent storage bin, an organic fertilizer conversion storage bin, and an oil-water bin. It can be seen that this patent is mainly aimed at occasions such as the catering industry and unit canteens where food waste is concentrated and the generation time is relatively fixed. Moreover, in terms of its composition, it has many functions, a long processing flow, and occupies a large area. Its essence is to serve food waste biomass utilization enterprises, and it is obviously not suitable for being put into the community for household food waste recycling and disposal.

[0005] Another example is the invention patent with application number 202111534281.5, which discloses an anti-entanglement stirring mechanism for a kitchen waste disposer. The patent provides an anti-entanglement stirring mechanism for a kitchen waste disposer, in which a knife body that can move axially is arranged on the stirring shaft to cut the vegetable leaves and peels that are entangled on the stirring shaft. It can be seen that the patent only addresses the problem of easy entanglement of vegetable leaves and the like in kitchen waste treatment. In fact, this problem is not a key issue for the mainstream mode of biomass utilization and disposal of kitchen waste at this stage. The key issue of biomass utilization and disposal of kitchen waste at this stage is how to effectively separate and recycle the hard bones in kitchen waste. If the hard bones in kitchen waste cannot be effectively separated, it will directly cause increased wear of subsequent processing equipment and even cause equipment blockage; at the same time, hard bones are also a kind of material that can be recycled and recycled. The difficulty of its resource utilization lies in the fact that perishable substances such as bone meat that has not been eaten clean remain on it. Taking the above reasons into consideration, biomass utilization companies that centrally recycle food waste often require food collectors to manually separate the hard bones when collecting food. Obviously, under this model, the hard bones in food waste cannot be completely separated and cannot be effectively utilized as resources.

[0006] In summary, although my country has a relatively complete set of processes for the recycling and treatment of food waste, there is no supporting facility for the recycling and disposal of food waste at the source of food waste, such as in the community, which makes the recycling and treatment of household food waste a difficulty and pain point in the current classification and recycling of domestic waste. At the same time, most of the current solutions for the recycling and treatment of food waste serve food waste biomass utilization companies, and the limited solutions for the community cannot be effectively connected with the mainstream mode of food waste biomass utilization and disposal. In addition, the key issue of hard bone separation related to the utilization and disposal of food waste biomass has not yet been solved. It can be seen that the development of a centralized collection and timely full-volume pretreatment device for household food waste in the community that connects biomass utilization is of great practical significance for promoting the implementation of the classification and treatment of domestic waste. Summary of the invention

[0007] The purpose of the present invention is to address a series of problems caused by the fact that household kitchen waste is often mixed with other garbage due to the lack of suitable recycling and processing equipment or many practical problems in the use of existing equipment. The present invention designs a community-based household kitchen waste centralized recycling and timely full-quantity pretreatment device connected with biomass utilization. The device can be used around the clock to centrally recycle and pre-pulp the kitchen waste that is generated daily in households but in small quantities. During the pre-pulping process, not only the food residues are crushed but also the organic matter remaining on the hard bones is stripped off. At the same time, by controlling the solid size in the kitchen waste slurry, large hard bones that will cause damage to subsequent processing equipment for biomass utilization are separated and recycled separately. The kitchen waste slurry after removing the large hard bones flows into a slurry temporary storage pool, thereby realizing centralized recycling, timely processing and full-quantity resource utilization of household kitchen waste, and at the same time achieving efficient connection with food waste biomass utilization enterprises, thereby "collecting slop as treasure" not only enables household kitchen waste to be effectively recycled, but also greatly reduces the amount of domestic waste disposal.

[0008] To achieve the above objectives, the present invention adopts the following technical solutions: A community household kitchen waste centralized collection and timely full-volume pretreatment device connected with biomass utilization comprises: a frame 1, a feeding funnel 2, a diversion component 3, two stirring barrels 4, a cleaning component 5, two stirrers 6 installed inside the stirring barrel 4, a support plate 7, two stirring core lifting components 8, a discharging funnel 9, a hard bone collection drawer 10, a hard bone sorting transmission component 11, a hard bone sorting drive component 12 and a shell.The diverter component 3 is composed of a diverter baffle 3-1, a steering gear 3-2 and a steering gear connector 3-3. The diverter baffle 3-1 is a circular plate with a circular opening with the same diameter as the feed port on the mixing barrel 4. The steering gear 3-2 drives the diverter baffle 3-1 to rotate. When the circular opening is aligned with the feed port of one of the mixing barrels 4, the feeding funnel 2 and the mixing barrel can be connected; at the same time, the feed port on the other mixing barrel 4 is sealed by the diverter baffle 3-1; the mixing barrel 4 is equipped with an agitator 6, and the agitator 6 and the mixing barrel 4 are matched with a conical surface. A stirring core lifting component 8 is installed below the agitator 6; two mixing barrels 4, two agitators 6 and two stirring core lifting components 8 constitute two identical groups with separation hard bones Pre-pulping unit; two groups of pre-pulping units are arranged symmetrically side by side in the device. When in use, only one feed port on the mixing barrel is open. When the amount of kitchen waste reaches 2 / 3 of its volume, the circular hole of the diverter baffle 3-1 is rotated 180°, and this feed port is closed for pre-pulping while the other feed port of the mixing barrel is opened, so that kitchen waste can be processed in time without causing queuing during peak hours; the agitator 6 is composed of a metal knife 6-1, a stirring core 6-2, a motor 6-3 installed in the stirring core 6-2, a rubber knife 6-4, a knife sheath 6-5, and a stirring core base 6-6. The metal knife 6-1 and the rubber knife 6-4 are fixed on the output shaft of the motor 6-3 by the knife sheath 6-5. The metal knife 6-1 is in the pulping process. The metal knife 6-1 and the rubber knife 6-4 play a main role in crushing during the pulping process, and the rubber knife 6-4 plays a main role in beating during the pulping process. Under the joint action of the metal knife 6-1 and the rubber knife 6-4, the solid residues such as vegetable leaves and fish bones in the kitchen waste are broken up, and the organic matter remaining on the large hard bones in the kitchen waste, such as the meat close to the bones that has not been eaten clean, is also separated, so that the kitchen waste is made into a kitchen waste slurry containing only large hard bones; the stirring core lifting assembly 8 is composed of a driving motor 8-1, a screw nut and its connecting piece 8-2, a screw 8-3, a lever 8-4, a rocker arm 8-5, a frame connecting piece 8-6, and a vertical lifting rod 8-7. One end of the vertical lifting rod 8-7 is fixed on the stirring core base 6-6 and the other end is connected to the lever 8-4. When the pulping is completed After the motor 6-3 stops working, the driving motor 8-1 in the stirring core lifting component 8 drives the screw 8-3 to rotate, driving the screw nut 8-2 to lift upward, and the stirring core 6-2 is lifted up a certain distance through the lever 8-4 connected to the screw nut 8-2. The kitchen waste slurry flows down from the gap between the stirring core 6-2 and the stirring barrel 4 into the discharge funnel 9, while the large pieces of hard bones remain in the stirring barrel 4. After the flow meter at the outlet of the stirring barrel 4 detects that no slurry is dripping, the stirring core lifting component 8 lifts the stirring core 6-2 to the highest point. At this time, the large pieces of hard bones are able to fall off and are dropped into the hard bone collection drawer 10 through the action of the hard bone sorting transmission component 11 and the hard bone sorting drive component 12, thereby realizing the separation of large pieces of hard bones in the kitchen waste.

[0009] The discharge funnel 9 is a square inverted cone hollow structure, with a hard bone sorting transmission component 11 and a hard bone sorting drive component 12 installed inside, and a hard bone collection drawer 10 installed at the front end.

[0010] Ball bearing slide rails are installed on both sides of the hard bone collection drawer 10 to achieve smooth movement, which is convenient for the staff to pull out the hard bone collection drawer 10 to recover the hard bones.

[0011] The rubber knife 6-4 is divided into two groups, upper and lower, each group is provided with 4 knife strips, and the length of the knife strips of the upper group is twice the length of the knife strips of the lower group.

[0012] The feeding funnel 2 is a hollow square basin structure, the inner wall of which is a combination of an upper straight wall and a lower inverted cone, and the outer wall is a square structure with a bottom. A hollow is formed between the inner and outer walls to store water, and a circle of fine holes is opened on the upper straight wall of the inner wall. When the water level in the hollow structure exceeds the position of the fine holes, water will spray out through the fine holes to flush the kitchen waste remaining in the feeding funnel into the mixing barrel, so as to achieve the purpose of cleaning the feeding funnel 2 and ensuring its cleanliness; at the bottom of the feeding funnel 2, two circular holes with the same position and size as the feeding port of the mixing barrel 4 are opened for the dropping of kitchen waste, and at the same time, there is a hole at the bottom connecting to the water outlet pipe 5-1 of the cleaning component 5 for water injection.

[0013] The cleaning assembly 5 is composed of a water injection pipe 5-1, a water injection flange adapter pipe 5-2, a water inlet flange adapter pipe 5-3, and a water pump 5-4. The water injection pipe 5-1 is connected to the feed funnel 2 to pump the cleaning water into the water storage hollow area formed between its inner wall and outer wall, and the horizontal water inlet flange adapter pipe 5-3 is connected to the water supply device.

[0014] The support plate 7 is fixed on the frame 1 and is used to place the mixing barrel 4 and the cleaning assembly 5. The area where the mixing barrel 4 is placed is raised to enhance its strength.

[0015] The hard bone sorting transmission assembly 11 is composed of a sorting baffle 11-1, a blanking inclined plate 11-2, and a hinge 11-3; the sorting baffle 11-1 and the blanking inclined plate 11-2 are connected by two hinges 11-3, and the baffle 11-1 is connected to the hard bone sorting drive assembly 12 by a screw nut 12-3 in the hard bone sorting drive assembly 12; the hard bone sorting transmission assembly 11 has two working positions, namely, the baffle 11-1 is located in the middle of the discharge funnel 9 and moved to the connection between the discharge funnel 9 and the hard bone collection drawer 10; when the baffle 11-1 moves axially to the connection between the discharge funnel 9 and the hard bone collection drawer 10, the blanking inclined plate 11-2 falls vertically due to the lack of support below, and the hard bones on the blanking inclined plate 11-2 fall into the collection drawer 10.

[0016] The hard bone sorting drive assembly 12 is composed of a drive motor 12-1, a lead screw 12-2, and a lead screw nut 12-3. The drive motor 12-1 is connected to the lead screw 12-2 through a coupling, driving the lead screw 12-2 to rotate, causing the lead screw nut 12-3 to move axially, and then driving the baffle 11-1 connected thereto to move together, so that the baffle 11-1 and the falling inclined plate 11-2 can be changed between two positions.

[0017] The beneficial effects of the present invention are: Compared with the prior art, the beneficial effects of the present invention include the following aspects.

[0018] (1) The device described in the present invention has two sets of pre-pulping units (including a mixing barrel, a stirrer and a stirring core lifting component) arranged side by side. When in use, only one mixing barrel feed port is opened through the "error-proofing" design of the diversion component. When the amount of kitchen waste reaches 2 / 3 of its volume, the diversion baffle in the diversion component rotates 180 degrees, closing the feed port of this mixing barrel for pre-pulping while opening the feed port of the other mixing barrel, so that kitchen waste can be processed in time without causing queuing during peak hours. In addition, a temporary storage pool for kitchen waste slurry is set up to meet the daily processing of kitchen waste in medium-sized communities.

[0019] (2) The device described in the present invention, through the combined action of the rubber knife and the metal knife, can not only crush the soft and easily entangled food waste such as long vegetable leaves into slurry, but also remove the residues attached to the hard bones, thereby pre-processing the entire amount of food waste into food waste slurry and smooth hard bones that are not easy to rot. The food waste slurry flows into the buried slurry pool for centralized temporary storage to facilitate efficient transportation by biomass utilization enterprises. After the hard bones are concentrated to a certain amount, they are specially recycled, thereby realizing the efficient resource utilization of the entire amount of food waste.

[0020] (3) The device described in the present invention controls the lifting height of the stirring core and utilizes the different sizes of the gaps formed between the stirring core and the stirring barrel after the stirring core is lifted, thereby achieving efficient separation of hard bones from the kitchen waste slurry. This not only solves the key problem of hard bone separation in the utilization and disposal of food waste biomass, but also ensures the effectiveness and thoroughness of hard bone separation, thereby effectively avoiding the hidden danger of damage to subsequent processing equipment caused by the presence of hard bones in the kitchen waste.

[0021] (4) The device of the present invention is in a fully enclosed state during the kitchen waste treatment process, and a cleaning component is also provided for the corresponding feeding funnel for the kitchen waste. During the kitchen waste treatment and temporary storage process, no odor, sewage, etc. will be generated to affect the environment, and no problem of poor user experience will be caused.

It should be understood that the specific embodiments described herein are only embodiments of a part of the present invention, rather than all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-10 shown.

[0035] A community household kitchen waste centralized collection and timely full-volume pretreatment device for connecting biomass utilization, comprising: a frame 1, a feeding funnel 2, a diversion component 3, two stirring barrels 4, a cleaning component 5, two stirrers 6 installed inside the stirring barrel 4, a support plate 7, two stirring core lifting components 8, a discharging funnel 9, a hard bone collection drawer 10, a hard bone sorting transmission component 11, a hard bone sorting drive component 12 and a shell, see Figure 1 and Figure 2 .in: The flow dividing component 3 is composed of a flow dividing baffle 3-1, a steering gear 3-2 and a steering gear connecting piece 3-3. The flow dividing baffle 3-1 is a circular plate with a circular opening having the same diameter as the feed opening on the mixing barrel 4. The steering gear 3-2 drives the flow dividing baffle 3-1 to rotate. When the circular opening is aligned with the feed opening of one of the mixing barrels 4, the feeding funnel 2 and the mixing barrel can be connected; at the same time, the feed opening on the other mixing barrel 4 is sealed by the flow dividing baffle 3-1, see Figure 3 and Figure 4 .

[0036] The interior of the mixing barrel 4 is provided with an agitator 6, which is matched with the mixing barrel 4 in a conical surface, and a stirring core lifting component 8 is provided below the agitator 6; two mixing barrels 4, two agitators 6 and two stirring core lifting components 8 constitute two groups of identical pre-pulping units with separation hard bones; the two groups of pre-pulping units are arranged symmetrically side by side in the device, and when in use, only one feeding port on the mixing barrel is in an open state, and when the amount of kitchen waste reaches 2 / 3 of its volume, the circular hole of the diversion baffle 3-1 is rotated 180°, and the feeding port of the other mixing barrel is opened while closing the feeding port for pre-pulping, so that the kitchen waste can be processed in time without causing queuing during the peak period of delivery, see Figure 4 .

[0037] The stirrer 6 is composed of a metal knife 6-1, a stirring core 6-2, a motor 6-3 installed in the stirring core 6-2, a rubber knife 6-4, a knife sheath 6-5, and a stirring core base 6-6. The metal knife 6-1 and the rubber knife 6-4 are fixed on the output shaft of the motor 6-3 by the knife sheath 6-5. The metal knife 6-1 mainly plays a crushing role in the pulping process, and the rubber knife 6-4 mainly plays a beating role in the pulping process. Under the joint action of the metal knife 6-1 and the rubber knife 6-4, solid residues such as vegetable leaves and fish bones in the kitchen waste are crushed, and at the same time, organic matter remaining on large hard bones in the kitchen waste, such as meat attached to bones that has not been eaten clean, is also separated, so that the kitchen waste is made into kitchen waste slurry containing only large hard bones; the rubber knife 6-4 is divided into two groups, upper and lower, each group is provided with 4 knife strips, the length of the upper group of knife strips is twice the length of the lower group of knife strips, see Figure 5 .

[0038] The stirring core lifting assembly 8 is composed of a driving motor 8-1, a screw nut and its connecting piece 8-2, a screw 8-3, a lever 8-4, a rocker 8-5, a frame connecting piece 8-6, and a vertical lifting rod 8-7. One end of the vertical lifting rod 8-7 is fixed on the stirring core base 6-6 and the other end is connected to the lever 8-4. When the pulping is completed, the motor 6-3 stops working, and the driving motor 8-1 in the stirring core lifting component 8 drives the screw 8-3 to rotate, driving the screw nut 8-2 to lift upward, and the screw nut 8-2 is connected to the screw nut 8-2. The lever 8-4 lifts the stirring core 6-2 upward for a certain distance, and the kitchen waste slurry flows down from the gap between the stirring core 6-2 and the stirring barrel 4 into the discharge funnel 9, while the large pieces of hard bones remain in the stirring barrel 4. After the flow meter at the outlet of the stirring barrel 4 detects that there is no more slurry dripping, the stirring core lifting component 8 lifts the stirring core 6-2 to the highest point, and the large pieces of hard bones are allowed to fall, and are caused to fall into the hard bone collection drawer 10 through the action of the hard bone sorting transmission component 11 and the hard bone sorting drive component 12, thereby realizing the separation of large pieces of hard bones in the kitchen waste. Figure 6 .

[0039] The discharge funnel 9 is a square inverted cone hollow structure, with a hard bone sorting transmission component 11 and a hard bone sorting drive component 12 installed inside, and a hard bone collection drawer 10 installed at the front end; ball bearing slide rails are installed on both sides of the hard bone collection drawer 10 to achieve smooth movement, which is convenient for pulling out the hard bone collection drawer 10 to realize hard bone recovery, see Figure 2 .

[0040] like Figure 7As shown, the feeding funnel 2 is a hollow square basin structure, the inner wall of which is a combination of an upper straight wall and a lower inverted cone, and the outer wall is a square structure with a bottom. A hollow is formed between the inner and outer walls to store water, and a circle of fine holes is opened on the upper straight wall of the inner wall. When the water level in the hollow structure exceeds the position of the fine holes, water will spray out through the fine holes to flush the kitchen waste remaining in the feeding funnel into the mixing barrel, so as to achieve the purpose of cleaning the feeding funnel 2 and ensuring its cleanliness; at the bottom of the feeding funnel 2, two circular holes with the same position and size as the feeding port of the mixing barrel 4 are opened for the dropping of kitchen waste, and at the same time, there is a hole at the bottom connecting to the water outlet pipe 5-1 of the cleaning component 5 for water injection.

[0041] like Figure 8 As shown, the cleaning component 5 is composed of a water injection pipe 5-1, a water injection flange adapter pipe 5-2, a water inlet flange adapter pipe 5-3, and a water pump 5-4. The water injection pipe 5-1 is connected to the feed funnel 2 to pump the cleaning water into the hollow water storage area formed between its inner wall and outer wall, and the water inlet flange adapter pipe 5-3 is connected to the water supply device.

[0042] like Fig. 9 As shown, the support plate 7 is fixed on the frame 1 and is used to place the mixing barrel 4 and the cleaning assembly 5. The area where the mixing barrel 4 is placed is raised to enhance its strength.

[0043] like Fig.10 As shown. The hard bone sorting transmission assembly 11 is composed of a sorting baffle 11-1, a blanking inclined plate 11-2, and a hinge 11-3; the sorting baffle 11-1 and the blanking inclined plate 11-2 are connected by two hinges 11-3, and the baffle 11-1 is connected to the hard bone sorting drive assembly 12 by a screw nut 12-3 in the hard bone sorting drive assembly 12; the hard bone sorting drive assembly 11 has two working positions, namely, the baffle 11-1 is located in the middle of the discharge funnel 9 and moved to the connection between the discharge funnel 9 and the hard bone collection drawer 10; when the baffle 11-1 moves axially to the connection between the discharge funnel 9 and the hard bone collection drawer 10, the blanking inclined plate 11-2 falls vertically due to the lack of support below, and the hard bones on the blanking inclined plate 11-2 fall into the collection drawer 10. The hard bone sorting drive assembly 12 is composed of a drive motor 12-1, a screw 12-2, and a screw nut 12-3. The driving motor 12-1 is connected to the lead screw 12-2 through a coupling, driving the lead screw 12-2 to rotate, causing the lead screw nut 12-3 to move axially, and then driving the baffle 11-1 connected thereto to move together, thereby realizing the transformation of the baffle 11-1 and the falling inclined plate 11-2 between two positions.

[0044] The working process of the present invention is: The kitchen waste is put into the mixing barrel 4 through the upper feeding funnel 2. When the kitchen waste reaches 2 / 3 of the total volume of the mixing barrel 4, the steering gear 3-2 arranged between the two mixing barrels 4 rotates, driving the diversion baffle 3-1 to rotate together, blocking the entrance of the full mixing barrel and opening the entrance of the mixing barrel on the other side. The kitchen waste can continue to be put into the empty barrel, and the full mixing barrel starts to process the kitchen waste in the barrel. Under the joint action of the metal knife 6-1 and the rubber knife 6-4, the solid residues such as vegetable leaves and fish bones in the kitchen waste are broken, and the organic matter remaining on the large hard bones in the kitchen waste, such as the flesh and bones that have not been eaten clean, is also separated, so that the kitchen waste is made into a kitchen waste slurry containing only large animal hard bones. After the treatment is completed, the stirring core lifting assembly 8 installed outside the barrel lifts the stirring core 6-2 for a short distance, so that the slurry flows down from the outlet of the mixing barrel into the discharge funnel 9 and enters the slurry temporary storage pool through the pipeline. When the flow sensor at the outlet of the mixing barrel detects that the slurry in the barrel has run out, the driving motor 12-1 below drives the sorting baffle 11-1 to move a certain distance toward the hard bone collection drawer 10, so that the sorting baffle 11-1 is located in the middle of the discharge funnel 9, and the mixing core 6-2 continues to lift up to the top, so that the unbroken animal bones fall on the falling inclined plate 11-2 connected to the sorting baffle 11-1. When the sensor at the outlet of the mixing barrel detects that no hard bones fall for a period of time, the sorting baffle 11-1 continues to move axially to the edge of the discharge funnel 9, and the falling inclined plate 11-2 falls vertically so that the hard bones on it fall into the hard bone collection drawer 10. Subsequently, the mixing core 6-2 and the sorting baffle 11-1 are all driven by their respective motors to return to the initial position, preparing for the next kitchen waste treatment.

[0045] The present invention does not involve parts that are the same as the prior art or can be implemented by using the prior art.
