Description

An environmentally friendly food waste treatment device Technical Field

[0001] This invention relates to the field of solid waste treatment, and more specifically to an environmentally friendly treatment device for kitchen waste. Background Technology

[0002] Food waste refers to leftover food after meals, food scraps discarded during food processing, and untreated wastewater generated during food washing and dishwashing. Its main components include fruit peels and bone fragments, food scraps, insoluble protein, fibrous and starchy non-soluble organic matter, with a highly complex composition depending on the type of food. Because food waste is rich in nutrients, if discharged directly into the environment without treatment, it will quickly decompose under suitable temperature and bacterial conditions, polluting the surrounding environment, attracting mosquitoes and flies, and resulting in a significant waste of resources. Therefore, the development of food waste treatment equipment can effectively degrade and comprehensively treat food waste, achieving waste reduction and resource utilization, which is of great significance for environmental protection and resource recycling.

[0003] In related technologies, such as the paper "Design of Integrated Food Waste Crushing and Dehydration Machine" published in the journal *Agricultural Engineering*, Vol. 9, No. 8, 2019, food waste treatment devices generally include a crusher and a dehydrator. The crusher mainly undertakes the crushing of food waste, while the dehydrator dehydrates the crushed food waste to facilitate the next step of aerobic fermentation. The crusher includes two crushing shafts with cutter discs. When food waste enters the crusher, it is crushed and torn by the cutter discs to a degree suitable for fermentation under the rotation of the crushing shafts. However, existing food waste has a complex composition and uneven size. When using the conventional crusher, larger pieces of waste will obstruct the normal fall of finer pieces, affecting crushing efficiency and ultimately the final treatment efficiency.

[0004] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention proposes an environmentally friendly food waste treatment device to solve the problem of low treatment efficiency of existing food waste treatment devices.

[0006] The present invention provides an environmentally friendly food waste treatment device with the following technical solution: it includes a transport and dewatering component, a shredding component, a dewatering component, and a water collection tank arranged sequentially from top to bottom; the transport and dewatering component is configured to transport food waste to the shredding component, the shredding component is configured to receive the food waste transported by the transport and dewatering component and shred it, the dewatering component is configured to dewater the food waste shredded by the shredding component, and the water collection tank is configured to receive the water discharged from the transport and dewatering component and the dewatering component;

[0007] The shredding assembly includes a first shredding roller and a second shredding roller. Both the first shredding roller and the second shredding roller extend along a first direction and are arranged side by side along a second direction. The first direction and the second direction are perpendicular to each other. The first shredding roller and the second shredding roller are centered along the first direction to form a first crushing zone and a second crushing zone.

[0008] The transport dewatering assembly has a first discharge port and a second discharge port along its transport direction. The first discharge port is used to discharge Class I waste, and the second discharge port is used to discharge Class II waste. The volume of Class I waste is larger than that of Class II waste. The first discharge port corresponds to the first crushing zone, and the second discharge port corresponds to the second crushing zone.

[0009] Optionally, the transport direction of the dewatering component is set at an angle to the first direction.

[0010] Optionally, the transport dewatering assembly includes:

[0011] Transport casing;

[0012] A drain conveyor belt is operably installed inside a transport housing, and the drain conveyor belt is provided with drain holes;

[0013] The first guide plate is located at the front end of the drain conveyor belt along the conveying direction, and extends downward at the end away from the drain conveyor belt. The first guide plate is a screen plate structure and is configured to accept Class I waste and filter Class II waste.

[0014] The second guide plate is located below the first guide plate and extends downward at an angle near the end of the drain conveyor belt. The second guide plate can receive Class II waste.

[0015] The first discharge port is located at the end of the first guide plate away from the drain conveyor belt, and the second discharge port is located at the end of the second guide plate close to the drain conveyor belt.

[0016] Optionally, a first drive roller and a second drive roller are provided inside the transport housing. Both the first drive roller and the second drive roller are capable of rotating around their own axes. A transport motor is provided on the transport housing. The output shaft of the transport motor is connected to the first drive roller or the second drive roller. The drain conveyor belt is wrapped around the outside of the first drive roller and the second drive roller.

[0017] Optionally, a first overflow trough is provided inside the transport housing, the first overflow trough is located below the upper section of the dewatering conveyor belt, a first overflow hole is provided on the side wall of the transport housing, the first overflow hole is connected to the first overflow trough, the first overflow hole is connected to a first water supply pipe, and the end of the first water supply pipe away from the first overflow hole extends to the water collection tank.

[0018] Optionally, the second guide plate is a screen plate structure, configured to accept Class II waste and filter moisture.

[0019] Optionally, a second overflow trough is formed on the transport shell, the second overflow trough is located below the second guide plate, and a second overflow hole is also provided on the side wall of the transport shell. The second overflow hole is connected to the second overflow trough and a second water supply pipe is connected to the second overflow hole. The end of the second water supply pipe away from the second overflow hole extends to the water collection tank.

[0020] Optionally, the second guide plate extends below the drain conveyor belt.

[0021] Optionally, the shredding assembly further includes a fixed crushing element, which is strip-shaped and disposed below the first shredding roller and the second shredding roller. The top surface of the fixed crushing element has two inclined surfaces that slope downward from the middle to both sides. The two sides of the fixed crushing element have a first crushing tooth and a second crushing tooth, respectively. The first crushing tooth corresponds to the first shredding roller, and the second crushing tooth corresponds to the second shredding roller.

[0022] Optionally, the end of the fixed crushing component located in the first crushing zone is lower than the end of the fixed crushing component located in the second crushing zone.

[0023] The beneficial effects of the present invention are as follows: The kitchen waste environmental protection treatment device of the present invention improves the structure of the transport and draining component so that the transport and draining component has a first discharge port and a second discharge port in its transport direction. The first discharge port and the second discharge port are respectively used to discharge the larger Class I waste and the smaller Class II waste. After the Class I waste and Class II waste are discharged, they are respectively located in different crushing areas of the shredding component, realizing the regional crushing of waste of different volumes and improving the crushing efficiency.

[0024] Furthermore, by setting the transport direction of the dewatering assembly to be at an angle to the first direction (the extension direction of the first shredding roller and the second shredding roller), the area of ​​the first and second discharge ports that can cover the corresponding crushing area in the first direction is increased. When the kitchen waste falls, it can be spread as much as possible in the corresponding crushing area and closer to the center of the corresponding crushing area in the first direction, thereby improving the uniformity of the falling material and further improving the crushing efficiency.

[0025] Furthermore, by setting the second guide plate to extend below the drain conveyor belt, the drain conveyor belt not only partially extends into the storage space formed by the first and second guide plates, but also forms a compression channel connecting the drain conveyor belt and the second guide plate to the second discharge port. During continuous operation, the drain conveyor belt can compress the Class II waste in the storage space, assisting in the initial removal of moisture from the Class II waste, avoiding excessive water content in the Class II waste, and preventing it from adhering between the first and second shredding rollers, thus affecting the crushing efficiency and crushing effect.

[0026] Furthermore, by setting fixed crushing components below the first and second shredding rollers, the material, after being crushed by the first and second shredding rollers, can enter the space between the first shredding roller and the fixed crushing component, and also enter the space between the second shredding roller and the fixed crushing component for secondary crushing, thereby improving crushing efficiency and effect. Simultaneously, the end of the fixed crushing component located in the first crushing area is lower than the end located in the second crushing area. When type I waste becomes clogged in the first crushing area, the second crushing area can still normally crush type II waste. The waste in the portion of the fixed crushing component corresponding to the second crushing area can slide to its corresponding portion in the first crushing area, allowing the crushing space in the second crushing area to be extended further after falling to the fixed crushing component, accelerating crushing efficiency and better ensuring the material supply to the downstream processes.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] As shown in Figures 1 to 9, an environmentally friendly kitchen waste treatment device provided in this embodiment of the invention includes a transport and dewatering assembly 200, a shredding assembly 400, a dewatering assembly 500, and a water collection tank 600 arranged sequentially from top to bottom.

[0044] The dewatering transport assembly 200 is configured to transport kitchen waste to the shredding assembly 400;

[0045] The shredding component 400 is configured to receive and shred the kitchen waste conveyed by the transport dewatering component 200.

[0046] The dewatering component 500 is configured to dewater the kitchen waste shredded by the shredding component 400, so as to facilitate subsequent aerobic fermentation.

[0047] The water collection tank 600 is configured to receive water discharged from the transport dewatering assembly 200 and the dewatering assembly 500;

[0048] The shredding assembly 400 includes a first shredding roller 401 and a second shredding roller 402. The first shredding roller 401 and the second shredding roller 402 both extend along a first direction and are arranged side by side along a second direction. The first direction and the second direction are perpendicular to each other. The first shredding roller 401 and the second shredding roller 402 are centered along the first direction to form a first crushing zone and a second crushing zone.

[0049] The transport dewatering assembly 200 has a first discharge port and a second discharge port along its transport direction. The first discharge port is used to discharge Class I waste, and the second discharge port is used to discharge Class II waste. The volume of Class I waste is larger than that of Class II waste. The first discharge port corresponds to the first crushing zone, and the second discharge port corresponds to the second crushing zone, thereby enabling the sorting and crushing of kitchen waste.

[0050] It is understandable that food waste is complex in composition and uneven in size. When conventional processing equipment crushes it, larger pieces of waste are more difficult to be rolled into the crushing rollers than smaller pieces, and the crushing process takes a long time. When all the waste is mixed and crushed, the large and small pieces of waste affect each other, which inevitably leads to low crushing efficiency.

[0051] In this embodiment, the structure of the transport and draining component 200 is improved so that the transport and draining component 200 has a first discharge port and a second discharge port in its transport direction. The first discharge port and the second discharge port are used to discharge the larger Class I waste and the smaller Class II waste, respectively. After the Class I waste and Class II waste are discharged, they are located in different crushing areas, so as to realize the crushing of waste of different volumes in different areas and improve the crushing efficiency.

[0052] In a further embodiment, the transport dewatering component 200 is inclinedly disposed above the shredding component 400, that is, the transport direction of the transport dewatering component 200 is set at an angle to the first direction.

[0053] In this embodiment, by setting the transport direction of the transport dewatering component 200 at an angle to the first direction, the area covered by the first and second discharge ports in the first direction is increased. When the kitchen waste falls, it can be spread as much as possible in the corresponding crushing area and closer to the center of the corresponding crushing area in the first direction, thereby improving the uniformity of the falling material and further improving the crushing efficiency.

[0054] In a further embodiment, referring to Figures 3, 4, 5 and 6, the transport dewatering assembly 200 includes a transport housing 201, a dewatering conveyor belt 202, a first guide plate 203 and a second guide plate 204.

[0055] The drain conveyor belt 202 is operably installed inside the transport housing 201. The drain conveyor belt 202 is provided with drain holes to facilitate the filtration of water mixed in the kitchen waste. Specifically, the transport housing 201 is provided with a first drive roller 205 and a second drive roller 206. Both the first drive roller 205 and the second drive roller 206 can rotate around their own axes. The transport housing 201 is provided with a transport motor 207. The output shaft of the transport motor 207 is connected to the first drive roller 205 or the second drive roller 206. The drain conveyor belt 202 is wrapped around the outside of the first drive roller 205 and the second drive roller 206.

[0056] The first guide plate 203 is located at the front end of the drain conveyor belt 202 along the conveying direction, and extends downward at the end away from the drain conveyor belt 202. The first guide plate 203 is a screen plate structure and is configured to accept Class I waste and filter Class II waste.

[0057] The second guide plate 204 is located below the first guide plate 203, and extends downward at one end near the drain conveyor belt 202. The second guide plate 204 can receive Class II waste.

[0058] The first discharge port is located at the end of the first guide plate 203 away from the drain conveyor belt 202, and the second discharge port is located at the end of the second guide plate 204 close to the drain conveyor belt 202.

[0059] In this embodiment, by setting a first guide plate 203 and a second guide plate 204 with opposite inclination directions at the front end of the drain conveyor belt 202, and with the first discharge port located at the front end of the first guide plate 203 and the second discharge port located at the rear end of the second guide plate 204, the structure and positional relationship of the first guide plate 203 and the second guide plate 204 can be used to conveniently distinguish between Class I and Class II waste and guide them to the first and second crushing zones of the shredding component 400, respectively. The design is ingenious, the structure is simple, and the practicality is strong.

[0060] Furthermore, to facilitate the discharge of water filtered by the dewatering conveyor belt 202 to the water collection tank 600, a first overflow trough 2015 is provided inside the transport housing 201. The first overflow trough 2015 is located below the upper section of the dewatering conveyor belt 202. A first overflow hole 2013 is provided on the side wall of the transport housing 201. The first overflow hole 2013 is connected to the first overflow trough 2015. The first overflow hole 2013 is connected to a first water supply pipe 208. The end of the first water supply pipe 208 away from the first overflow hole 2013 extends to the water collection tank 600.

[0061] In a further embodiment, the second guide plate 204 is a sieve plate structure, configured to receive Class II waste and filter moisture. By setting the second guide plate 204 as a sieve plate structure, the moisture mixed in the Class II waste can be further filtered, facilitating subsequent crushing processing.

[0062] Furthermore, to facilitate the discharge of water filtered by the second guide plate 204 to the water collection tank 600, a second overflow trough 2016 is formed on the transport housing 201. The second overflow trough 2016 is located below the second guide plate 204. A second overflow hole 2014 is also provided on the side wall of the transport housing 201. The second overflow hole 2014 is connected to the second overflow trough 2016. The second overflow hole 2014 is connected to a second water supply pipe 209. The end of the second water supply pipe 209 away from the second overflow hole 2014 extends to the water collection tank 600.

[0063] Furthermore, for ease of assembly and disassembly, the transport housing 201 includes a main housing 2011 and an auxiliary housing 2012, which are detachably connected. The drain conveyor belt 202 and the first overflow trough 2015 are installed on the main housing 2011, and the first guide plate 203 and the second guide plate 204 are installed on the auxiliary housing 2012. The second overflow trough 2016 is formed in the auxiliary housing 2012.

[0064] In a further embodiment, the second guide plate 204 extends below the drain conveyor belt 202.

[0065] In this embodiment, the second guide plate 204 extends below the drain conveyor belt 202, so that the drain conveyor belt 202 not only partially extends into the storage space 210 formed by the first guide plate 203 and the second guide plate 204, but also forms a compression channel connecting the drain conveyor belt 202 and the second guide plate 204 to the second discharge port. During continuous operation, the drain conveyor belt 202 can compress the Class II waste in the storage space 210, assisting in the initial removal of moisture from the Class II waste. Because Class II waste is small in volume, it is more likely to absorb moisture, and therefore has a relatively high moisture content. By compressing and removing water from the Class II waste, excessive water content in the waste can be avoided, preventing it from adhering between the first shredding roller 401 and the second shredding roller 402, thus affecting the crushing efficiency and crushing effect.

[0066] In a further embodiment, the shredding assembly 400 further includes a fixed shredding component 403, which is strip-shaped and disposed below the first shredding roller 401 and the second shredding roller 402. The top surface of the fixed shredding component 403 has two inclined surfaces 4033 that slope downward from the middle to both sides. The two sides of the fixed shredding component 403 have a first shredding tooth 4031 and a second shredding tooth 4032, respectively. The first shredding tooth 4031 corresponds to the first shredding roller 401, and the second shredding tooth 4032 corresponds to the second shredding roller 402.

[0067] In this embodiment, by setting a fixed crushing component 403 below the first shredding roller 401 and the second shredding roller 402, the material, after being crushed by the first shredding roller 401 and the second shredding roller 402, can enter between the first shredding roller 401 and the fixed crushing component 403, and between the second shredding roller 402 and the fixed crushing component 403 for secondary crushing, thereby improving crushing efficiency and crushing effect.

[0068] In a further embodiment, the end of the fixed crushing member 403 located in the first crushing region is lower than the end of the fixed crushing member 403 located in the second crushing region. That is, the fixed crushing member 403 is inclined downward from the second crushing region to the first crushing region.

[0069] It is understandable that larger types of waste are relatively difficult to crush and are prone to clogging. When the first crushing area is clogged, the second crushing area crushes the second type of waste normally. At the same time, the portion of the fixed crusher 403 corresponding to the first crushing area is gradually reduced in size due to the blockage in the first crushing area. At this time, the portion of the waste corresponding to the fixed crusher 403 corresponding to the second crushing area can slide to its corresponding portion in the first crushing area. This allows the crushing space in the second crushing area to be extended further after the material falls to the fixed crusher 403, thus accelerating the crushing efficiency and better ensuring the material supply to the downstream process.

[0070] In a further embodiment, the first shredding roller 401 and the second shredding roller 402 rotate at different speeds.

[0071] In this embodiment, by setting the first shredding roller 401 and the second shredding roller 402 to have different rotation speeds, the first shredding roller 401 and the second shredding roller 402 can better entrain the material when rotating, and the difference in rotation speed can better shred the material, thereby improving the crushing effect and crushing efficiency.

[0072] To facilitate control of the rotation of the first shredding roller 401 and the second shredding roller 402, in one embodiment, the shredding assembly 400 further includes two shredding motors, each connected to the first shredding roller 401 and the second shredding roller 402 respectively. The shredding motors allow for convenient control of the rotational speeds of the first shredding roller 401 and the second shredding roller 402. In other embodiments, the shredding assembly 400 also includes a shredding motor connected to either the first shredding roller 401 or the second shredding roller 402. A transmission structure is provided between the first shredding roller 401 and the second shredding roller 402, configured such that the first shredding roller 401 and the second shredding roller 402 rotate synchronously in opposite directions at different speeds.

[0073] In a further embodiment, the dehydration component 500 uses a spiral dehydrator in the related art for dehydration, which will not be described in detail here.

[0074] In a further embodiment, the kitchen waste environmental protection treatment device of the present invention also includes a frame for supporting the dehydration component 500, the shredding component 400 and the transport and dewatering component 200.

[0075] Based on the above embodiments, the usage principle and working process of the present invention are as follows:

[0076] First, the kitchen waste is poured onto the drain conveyor belt 202. The kitchen waste moves along direction a (see Figure 2). During this process, the water mixed in the kitchen waste will enter the first overflow tank 2015 through the drain holes on the drain conveyor belt 202 along path b (see Figure 4). The water in the first overflow tank 2015 enters the first water supply pipe 208 through the first overflow hole 2013. Finally, the water enters the collection tank 600, realizing the initial draining of the kitchen waste.

[0077] After draining, the kitchen waste reaches the top of the first guide plate 203. Larger waste (Category I) remains on the first guide plate 203 and eventually enters the shredding assembly 400 along path c. Smaller waste (including granular, blocky, and paste-like materials) enters the compression chamber through the first guide plate 203. During the operation of the draining conveyor belt 202, this waste is compressed, causing some of its internal moisture to be squeezed out, thus undergoing secondary dehydration. The water removed from the waste travels along path d. The waste enters the second overflow tank 2016 and flows into the collection tank 600 through the second overflow hole 2014 and the second water supply pipe 209. The waste that has been squeezed out of water enters the shredding assembly 400 along path e. Because the waste is small in size and has a strong water absorption capacity, the water content of the waste is relatively high. After secondary dehydration, the water content of the waste can be further reduced, preventing the waste from adhering to the first shredding roller 401 and / or the second shredding roller 402 of the shredding assembly 400 and affecting the crushing efficiency.

[0078] It is understandable that, referring to Figures 2 and 8, larger Class I waste enters the shredding assembly 400 from region x in Figure 8 (region x belongs to the first crushing region), while smaller Class II waste enters the shredding assembly 400 from region y in Figure 8 (region x belongs to the second crushing region). Thus, the first crushing region of the first shredding roller 401 and the second shredding roller 402 mainly processes the larger Class I waste, while the second crushing region mainly processes the smaller Class II waste. When the larger Class I waste is blocked, it does not affect the processing of the smaller Class II waste.

[0079] The first shredding roller 401 and the second shredding roller 402 rotate in the g direction as shown in Figure 9. After being shredded by the first shredding roller 401 and the second shredding roller 402, the kitchen waste falls to the fixed crushing component 403, where it undergoes secondary crushing through the first shredding roller 401 and the first crushing tooth 4031, as well as the second shredding roller 402 and the second crushing tooth 4032. At this time, if the first type of waste on the first and second crushing rollers becomes clogged, the material prepared for secondary crushing tends to move in the f direction (refer to Figure 7) due to the inclined arrangement of the fixed crushing component 403. This increases the processing area for secondary crushing of the second type of waste, improves crushing efficiency, and ensures the material supply for the next process.

[0080] After crushing, the material enters the dewatering component 500 for compression and dewatering. The water enters the water collection tank 600 through the bottom of the dewatering component 500. The dewatered material then enters the fermentation device for aerobic fermentation.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
