Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment. More specifically, the present invention relates to a processing device for preparing organic fertilizer from kitchen waste. Background Art

[0002] Kitchen waste is an important raw material for organic fertilizers. It is usually packaged in plastic bags. Therefore, when utilizing kitchen waste, it is necessary to separate the plastic bags from the kitchen waste.

[0003] Existing Chinese patent: A device for splitting and cutting the plastic bags containing kitchen waste (CN103072726B). This device can realize the combined actions of splitting and cutting plastic bags, slapping and dispersing, and blowing to remove the bags, ensuring that in the bag-breaking process of kitchen waste, no fragments of the plastic bags are generated, especially achieving bag-breaking without fragmentation, enabling the kitchen waste to be de-bagged, and the plastic bags not being covered by the waste, with remarkable effects.

[0004] After the kitchen waste is packed into plastic bags, due to the different specifications of each plastic bag and the different amounts of kitchen waste filled in each plastic bag, garbage bags of different sizes are formed. However, the above-mentioned equipment can only cut regular-sized garbage bags. When cutting small garbage bags, the small garbage bags will pass through the middle of the circular array of knives, resulting in incomplete cutting or even missed cutting, thus causing the kitchen waste and the plastic bags to not be completely separated.

Detailed implementation mode

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Embodiment 1

[0035] A processing device for preparing organic fertilizer from kitchen waste, as Figures 1 - 6 shown, includes a base 1, a box body 2 and a first connecting plate 3; there are four bases 1; the box body 2 is bolted to all the bases 1 together; the first connecting plate 3 is bolted to the box body 2; it also includes a cylinder 4, a hopper 5, a first cutter 6, a second cutter 201 and a separation component; the cylinder 4 is penetrated through the first connecting plate 3; the bottom of the box body 2 is inclined away from the cylinder 4; the upper end of the cylinder 4 is communicated and welded with the hopper 5; six first cutters 6 distributed in a ring are welded inside the cylinder 4; the first cutter 6 is in the shape of a right trapezoid; the first cutter 6 is used to cut open garbage bags of different sizes; a second cutter 201 is welded on both sides of each first cutter 6; six second cutters 201 distributed in a ring are welded at the lower part inside the cylinder 4, and each second cutter 201 is located between two adjacent first cutters 6, and the second cutter 201 is used to cut open the small garbage bags falling at the angle between the first cutter 6 and the cylinder 4; the separation component is connected to the box body 2; the separation component is used to separate plastic bags and kitchen waste.

[0036] It further includes a blockage prevention component; a blockage prevention component is connected to the first connecting plate 3; the blockage prevention component includes a housing 202, an electric push rod 203, a linkage frame 204, a first ring 205, a first round rod 206, a lever 207 and a driving unit; two housings 202 are bolted to the lower side of the first connecting plate 3; an electric push rod 203 is fixedly connected to the inner side of each housing 202; the telescopic end of each electric push rod 203 is fixedly connected to a linkage frame 204, and the linkage frame 204 is slidably connected to the cylinder 4; all the upper ends of the linkage frames 204 are bolted together to form a first ring 205, and the first ring 205 is slidably connected to the cylinder 4; twelve first round rods 206 are rotatably connected to the first ring 205, and each first round rod 206 is located at the included angle between the corresponding first cutter 6 and the cylinder 4; a lever 207 is welded to each first round rod 206, and the lever 207 is used to push the small garbage bag downward to prevent the small garbage bag from getting stuck on the second cutter 201 due to its too low weight; a driving unit is connected to the first ring 205; the driving unit is used to drive the first round rod 206 to rotate.

[0037] The driving unit includes a first motor 208 and a spur gear 209; six first motors 208 are fixedly connected to the first ring 205; the output end of each first motor 208 is fixedly connected to the corresponding first round rod 206; a spur gear 209 is fixedly connected to each first round rod 206; every two adjacent spur gears 209 mesh with each other.

[0038] It further includes a first auxiliary component; a first auxiliary component is connected to the first ring 205; the first auxiliary component includes a second ring 2010, a second round rod 2011 and a limiting rod 2012; the lever 207 is inclined downward; a second ring 2010 is bolted to the first ring 205, and the second ring 2010 is slidably connected to the cylinder 4, and all the first round rods 206 are rotatably connected to the second ring 2010, and the second ring 2010 is made of alloy material; the upper side of the second ring 2010 is an annular inclined plane, which is used to guide the garbage to prevent the garbage from remaining on the upper side of the first ring 205; a second round rod 2011 is rotatably connected to the upper end of each first round rod 206; a limiting rod 2012 is welded to each second round rod 2011, and the limiting rod 2012 slides at the included angle between the corresponding first cutter 6 and the cylinder 4, and the limiting rod 2012 is used to prevent the garbage bag from getting stuck in the gap between the first round rod 206 and the cylinder 4.

[0039] During use, the garbage bag is placed into the funnel 5. After being guided by the funnel 5, it drops downward into the cylinder 4, and then falls into the box body 2 from the middle of the gaps between the six first cutting blades 6. Since the first cutting blades 6 are in the shape of right-angled trapezoids, that is, the size of the gaps in the middle of the six first cutting blades 6 decreases from top to bottom. When the large garbage bag drops, it contacts the upper part of the first cutting blade 6, so that the large garbage bag is cut by the upper part of the first cutting blade 6. When the small garbage bag drops, it contacts the lower part of the first cutting blade 6, so that the small garbage bag is cut by the lower part of the first cutting blade 6. That is, both the large garbage bag and the small garbage bag can be cut by the first cutting blade 6. During this process, only the side position of the garbage bag is cut by the first cutting blade 6, and the head and tail of the garbage bag are still connected together. After that, the garbage bag and the kitchen waste are sorted and collected through the separation component. During use, through the cooperation of the six first cutting blades 6 in the shape of right-angled trapezoids, the large garbage bag and the small garbage bag during falling are cut in sequence, avoiding the problem of incomplete separation caused by the inability of the existing equipment to cut the small garbage bag. Moreover, only the side position of the garbage bag is cut by the first cutting blade 6, so that the head and tail of the garbage bag are still connected together, and no garbage bag fragments will be generated, which is convenient for separating the garbage bag from the kitchen waste.

[0040] After the garbage bag rolls from the funnel 5 into the cylinder 4, some small garbage bags will drop into the gaps between two adjacent first cutting blades 6 and the cylinder 4, resulting in cutting failure. At this time, by arranging the second cutting blade 201 between two first cutting blades 6 and the cylinder 4 to cut the small garbage bag, the problem of cutting failure caused by the small garbage bag dropping into the gaps between two adjacent first cutting blades 6 and the cylinder 4 is effectively avoided.

[0041] When the small garbage bag drops to the middle of the gaps corresponding to the three second cutting blades 201, due to the relatively low self-weight of some small garbage bags, the small garbage bag gets stuck on the three second cutting blades 201 and cannot drop. At this time, the first motor 208 is started. The first motor 208 drives the first round rod 206 to rotate. The first round rod 206 drives the spur gear 209 to rotate. The spur gear 209 drives another adjacent spur gear 209 to rotate, thereby driving another first round rod 206 to rotate. The first round rod 206 drives the lever 207 to perform a circular motion, so that the lever 207 moves above the small garbage bag. Then the electric push rod 203 is started. The electric push rod 203 drives the linkage frame 204 to move downward. The linkage frame 204 drives the first ring 205 to move downward. The first ring 205 drives the parts thereon to move downward, so that the lever 207 toggles the small garbage bag to move downward, pushing the small garbage bag away from the three second cutting blades 201 from top to bottom. During this process, the small garbage bag is cut by the second cutting blade 201. During use, the small garbage bag stuck on the second cutting blade 201 is pushed down by the lever 207 to avoid blockage.

[0042] After the garbage bag is cut, some of the kitchen waste inside it will fall out, and a small amount of kitchen waste will fall onto the upper side of the first ring 205, resulting in the phenomenon of residual kitchen waste. Therefore, a second ring 2010 is arranged on the upper side of the first ring 205. Since the upper side of the second ring 2010 is an inclined plane, the kitchen waste is guided downward into the box body 2, effectively avoiding the phenomenon of residual kitchen waste.

[0043] When the small garbage bag falls past the second cutter 201, the handle part on it may hang on the first round rod 206, resulting in a failure to fall and a blockage phenomenon. At this time, by arranging the second round rod 2011 and the limit rod 2012 to limit the garbage bag, the problem of blockage caused by the handle of the garbage bag hanging on the first round rod 206 is effectively avoided. When the first round rod 206 rotates, the limit rod 2012 is blocked and limited by the cylinder 4 and the first cutter 6 and remains stationary, so that the first round rod 206 rotates relative to the limit rod 2012. When the first round rod 206 moves up and down, the limit rod 2012 is blocked and limited by the cylinder 4 and the first cutter 6, so that the first round rod 206 drives the second round rod 2011 to move up or down, and the second round rod 2011 drives the limit rod 2012 to move up or down.

[0044] Embodiment 2

[0045] On the basis of Embodiment 1, as Figures 1 - 2 and Figures 7 - 8 shown, the separation component includes a first housing 2013, a filter screen 2014, a pipeline 2015, a pump body 2016, a stirring unit, a taking-out unit and an opening and closing unit; two first housings 2013 are connected and bolted to the box body 2; clear water is arranged inside the box body 2, and the clear water submerges the first housing 2013; a filter screen 2014 is arranged on each first housing 2013, and the filter screen 2014 is set as a detachable structure; a pipeline 2015 is connected between the two first housings 2013, and the pipeline 2015 can be set as a plastic hose, and the pipeline 2015 can also be set as a steel pipe; a pump body 2016 is installed on each pipeline 2015, and the pump body 2016 is fixedly connected to the box body 2; a stirring unit is connected to the box body 2; the stirring unit is used for stirring the clear water; a taking-out unit is connected to the box body 2; the taking-out unit is used for taking out the plastic bag in the box body 2; an opening and closing unit is connected to the box body 2; the opening and closing unit is used for taking out the kitchen waste in the box body 2.

[0046] The stirring unit includes a second motor 2017, a third round rod 2018 and blades 2019; three second motors 2017 are bolted to the box body 2; the output end of each second motor 2017 is fixedly connected with a third round rod 2018, and the third round rod 2018 is rotatably connected to the box body 2; a plurality of blades 2019 are welded on each third round rod 2018.

[0047] The extraction unit includes a bolt 2020, a connecting frame 2021 and a first frame 2022; two bolts 2020 are welded on the box body 2, and the bolts 2020 are made of alloy material; a connecting frame 2021 is inserted on each bolt 2020, and the connecting frame 2021 is in contact with the box body 2; a first frame 2022 is fixedly connected among all the connecting frames 2021, and the first frame 2022 slides inside the box body 2; several round holes are formed at the bottom of the first frame 2022.

[0048] The opening and closing unit includes a second housing 2023 and an electric door 2024; the second housing 2023 is connected and welded to the lower side of the box body 2; two electric doors 2024 are connected to the second housing 2023.

[0049] The specific steps for the separation component to classify and collect kitchen waste and garbage bags in Embodiment 1 are as follows: the cut garbage bag falls into the box body 2 and is mixed with the clear water therein. The pump body 2016 is started to make the clear water circulate in the box body 2, the first housing 2013 and the pipeline 2015. The circulating clear water is beneficial to separating the kitchen waste and the garbage bag. During this process, the kitchen waste is intercepted and filtered by the filter screen 2014. At the same time, the second motor 2017 is started to drive the third round rod 2018 to rotate, and the third round rod 2018 drives the blade 2019 to move, so that the blade 2019 pats the garbage bag, and the kitchen waste flows out from the cut of the garbage bag, thus separating the garbage bag and the kitchen waste. The garbage bag will float on the liquid surface, and the circulating liquid drives the garbage bag to move to the right, making it gather above the first frame 2022. When there are relatively many gathered garbage bags, manually pull the connecting frame 2021 upward to disengage from the bolt 2020. The connecting frame 2021 drives the first frame 2022 to move upward, and the first frame 2022 drives the plastic bag above it to move. The waste water flows out from the round holes on the first frame 2022, thus fishing out the plastic bag from the waste water. Then manually take out the garbage bag. During the sedimentation process of the kitchen waste, it slides along the inclined plane at the bottom of the box body 2 into the second housing 2023 and is received on the upper side of the lower electric door 2024. When it is necessary to take out the kitchen waste, the upper electric door 2024 is closed to separate the second housing 2023 from the box body 2. Then the lower electric door 2024 is opened to make the kitchen waste flow out from the second housing 2023, completing the classification and collection operation of the kitchen waste and the garbage bag.

[0050] Embodiment 3

[0051] On the basis of Embodiment 2, such as Figures 1 - 2 and Figures 8 - 9As shown, it further includes an interception component; an interception component is connected to the second housing 2023; the interception component includes a second connecting plate 2025, a second frame 2026 and a fourth round rod 2027; the second connecting plate 2025 is inserted into the second housing 2023, and the second connecting plate 2025 is made of alloy material; the second connecting plate 2025 is welded with the second frame 2026, and the second frame 2026 is slidably connected to the second housing 2023; ten fourth round rods 2027 are welded on the second frame 2026, and the non-floating plastic bags are intercepted by the fourth round rods 2027.

[0052] It further includes a water removal component; a water removal component is connected to the second housing 2023; the water removal component includes a torsion spring rotating shaft 2028, a third connecting plate 2029 and a fifth round rod 2030; two torsion spring rotating shafts 2028 are rotatably connected to the second housing 2023; a third connecting plate 2029 is connected to each torsion spring rotating shaft 2028; the third connecting plate 2029 is in contact with the second housing 2023; a fifth round rod 2030 is welded on each third connecting plate 2029, the fifth round rod 2030 is in contact with the second housing 2023, and the fifth round rod 2030 is in contact with the second frame 2026. The water in the plastic bags hanging on the fourth round rods 2027 is squeezed out by the fifth round rods 2030; all the fourth round rods 2027 are in contact with the corresponding fifth round rods 2030; a number of grooves 91 are formed on each fourth round rod 2027, and the opening of the groove 91 is smaller than its inner diameter.

[0053] During the process of separating the garbage bags from the kitchen waste, some garbage bags will move towards the second housing 2023. At this time, the garbage bags are intercepted by the fourth round rods 2027, so that the garbage bags are hung on the fourth round rods 2027 to avoid incomplete separation. After taking out the kitchen waste in the second housing 2023, manually pull the second connecting plate 2025 to move, and the second connecting plate 2025 drives the second frame 2026 and the parts thereon to move, so that the garbage bags hanging on the fourth round rods 2027 are pulled out of the second housing 2023, thereby taking out the garbage bags.

[0054] During the process of removing the garbage bag on the fourth round rod 2027, since the head and tail of the garbage bag are not cut off, some waste water remains in the garbage bag. When manually removing it, the waste water in the garbage bag will flow out to the ground, polluting the working environment. At this time, the fourth round rod 2027 drives the garbage bag to move to the right, so that the garbage bag moves to the lower side of the fifth round rod 2030. The fourth round rod 2027 continues to move to the right, so that the garbage bag passes through the fifth round rod 2030 to the right, thereby squeezing the garbage bag through the fifth round rod 2030 to squeeze out the waste water remaining in it. At the same time, the garbage bag will also exert a reaction force on the fifth round rod 2030, causing the fifth round rod 2030 to drive the third connecting plate 2029 to flip around the torsion spring rotating shaft 2028, so that the garbage bag can smoothly pass through the fifth round rod 2030. During this process, the lower fifth round rod 2030 squeezes the garbage bag into the groove 91 of the fourth round rod 2027. Since the opening of the groove 91 is small and the inner diameter is large, the garbage bag is fixed through the groove 91, so that it is close to the lower side of the fourth round rod 2027, and then the garbage bag is taken out through the fourth round rod 2027, avoiding that when the fourth round rod 2027 takes out the hanging garbage bag, the hanging garbage bag is blocked by the second housing 2023 and separated from the fourth round rod 2027, thereby avoiding increasing the cleaning difficulty.

[0056] On the basis of Embodiment 3, as Figure 1 , Figure 2 , Figure 6 and Figure 10 shown, it further includes a second auxiliary component; a second auxiliary component is connected to the second cutter 201 and the second housing 2023; the second auxiliary component includes a third cutter 301, a fourth connecting plate 302, a telescopic cylinder 303, a fifth connecting plate 304 and a protrusion 305; a third cutter 301 is rotatably connected to the lower part of each second cutter 201 through a torsion spring; a fourth connecting plate 302 is slidably connected in the second housing 2023; a telescopic cylinder 303 is bolted to the second housing 2023, and the telescopic end of the telescopic cylinder 303 is fixedly connected to the fourth connecting plate 302; a fifth connecting plate 304 corresponding to the number of the fourth round rods 2027 is welded on the fourth connecting plate 302; a plurality of protrusions 305 are welded on the upper side of each fourth round rod 2027.

[0057] When the small garbage bag falls past the second cutting knife 201, the relatively small garbage bag continues to fall through the gaps between the three second cutting knives 201 until it touches the third cutting knife 301. Then, the relatively small garbage bag is cut open by the third cutting knife 301. After the relatively large garbage bag falls to the gaps between the three second cutting knives 201, the relatively large garbage bag is cut open by the second cutting knife 201, and it continues to move downward to touch the third cutting knife 301. The weight of the garbage in the relatively large garbage bag is heavier than that in the relatively small garbage bag. Therefore, during the falling process of the relatively large garbage bag, it will push the third cutting knife 301 to flip towards the second cutting knife 201, thereby enabling the relatively large garbage bag to fall smoothly and avoiding blockage. That is, by setting the third cutting knife 301, the cutting range can be further increased without blockage.

[0058] When the fourth round rod 2027 intercepts the plastic bag, some kitchen waste will hang on the hanging part of the garbage bag, resulting in incomplete separation. At the same time, when the garbage bag is taken out, the kitchen waste will be taken out together with the garbage bag, resulting in the need for subsequent manual cleaning of the kitchen waste on the garbage bag. At this time, the telescopic cylinder 303 is started, and the telescopic cylinder 303 drives the fifth connecting plate 304 to move linearly back and forth, so that the fifth connecting plate 304 pats the hanging part of the garbage bag, thereby knocking off the garbage on it to avoid residue. And during this process, the garbage bag is fixed by the protrusion 305 to prevent the fifth connecting plate 304 from knocking off the garbage bag from the fourth round rod 2027.

[0059] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
