Description

Technical Field

[0001] This invention relates to the field of kitchen waste treatment equipment technology, specifically to a kitchen waste sorting and crushing machine. Background Technology

[0002] Food waste, commonly known as swill, is a general term for restaurant waste and kitchen scraps. It primarily consists of household waste generated during daily consumption and is the most significant type of food waste. It includes food processing scraps (kitchen scraps) and uneaten food from households, schools, canteens, and the catering industry. Its composition is complex, mainly a mixture of oil, water, fruit peels, vegetables, rice, flour, fish, meat, bones, as well as discarded tableware, plastics, paper towels, and other materials. Food waste is characterized by its high rate of decomposition and spoilage, emitting a foul odor and spreading bacteria and viruses.

[0003] As people become more environmentally conscious, environmental pollution and resource waste have received significant attention. Typically, people simply throw kitchen waste directly into trash cans, and garbage trucks regularly collect the waste and transport it to waste treatment plants. However, kitchen waste generally contains various components, with high water content and abundant organic matter, making it particularly prone to bacterial growth, leading to rotting and unpleasant odors. Therefore, crushing equipment is usually needed to break down the waste, followed by oil-water separation, organic matter fermentation, and inorganic matter collection to ensure the full recycling of kitchen waste.

[0004] Existing crushing equipment cannot separate inorganic materials such as garbage bags and plastic bottles from organic materials such as fruit peels, vegetables, and bones in kitchen waste. Therefore, before crushing, kitchen waste needs to be sorted manually to remove inorganic materials such as garbage bags and plastic bottles. Kitchen waste has an odor, and manual sorting is not only inefficient but also easy to cause harm to people. Summary of the Invention

[0005] To address at least one technical problem in the prior art, the present invention provides a kitchen waste sorting and crushing machine that can automatically crush kitchen waste and automatically separate inorganic materials such as garbage bags and plastic bottles from organic materials such as fruits.

[0022] Reference Figure 1 This invention provides a kitchen waste sorting and crushing machine, including a protective shell, a sorting and crushing component 2, and a feeding and conveying component 3. The protective shell includes an outer shell 11 and a feeding hopper 12, a discharging hopper 13, and a collection container 14 disposed inside the outer shell 11. The sorting and crushing component 2 is used to crush kitchen waste and separate inorganic materials such as plastic bags and plastic bottles from organic materials such as fruit peels, vegetables, and bones. The sorting and crushing component 2 has a feeding inlet 210. The feeding and conveying component 3 is horizontally disposed above the sorting and crushing component 2 and is used to automatically convey kitchen waste from the feeding hopper 12 to the feeding inlet 210. The feeding and conveying component 3 includes a conveying cylinder 31, a material drop limiter 32 disposed at the end of the conveying cylinder 31 and located above the feeding inlet 210, and a spiral conveying unit 33 disposed in the conveying cylinder 31.

[0023] Furthermore, the sorting and crushing assembly 2 includes a filter cylinder 21 disposed above the discharge hopper 13, a first rotating shaft 22 disposed within the filter cylinder 21, multiple sets of blade units 23 distributed along the axial direction on the first rotating shaft 22, multiple sets of crushing units 24 distributed along the axial direction on the first rotating shaft 22, a rotary motor 25 driving the first rotating shaft 22 to rotate along the axial direction, and at least two anti-winding plates 27. Multiple first flanges 26 are fixed at intervals along the axial direction of the first rotating shaft 22. At least two limiting slots are opened at intervals along the circumferential direction of the first flanges 26. The anti-winding plates 27 extend along the axial direction of the first rotating shaft 22 and are disposed in the multiple limiting slots. One end of the filter cylinder 21 is closed, and the other end is connected to the collection container 14. The filter cylinder 21 is provided with a feed inlet 210.

[0024] When kitchen waste is poured into the feed hopper 12, it automatically falls from the lower end of the feed hopper 12 into the conveying cylinder 31. Then, the screw conveyor unit 33 horizontally conveys the kitchen waste to the discharge limiting member 32. The kitchen waste entering the discharge limiting member 32 automatically falls from the feed inlet 210 into the filter cylinder 21. The rotary motor 25 drives the crushing unit 24 to rotate around the axis of the first rotating shaft 22, thereby crushing the kitchen waste. The crushed kitchen waste automatically falls into the discharge hopper 13. While crushing the kitchen waste, the blade unit 23 rotates at high speed with the first rotating shaft 22, thereby generating a strong wind that blows towards the collection container 14. The strong wind blows inorganic materials such as plastic bags and ropes into the collection container 14, thus completing the crushing and sorting of kitchen waste. At the same time, since at least two anti-winding plates 27 are provided on the outside of the first rotating shaft 22, long strip-shaped objects will not get tangled on the first rotating shaft 22.

[0025] Furthermore, the feed inlet 210 is located at the closed end of the filter cylinder 21, and at least one set of blade units 23 is located at the closed end of the filter cylinder 21 to facilitate the blowing of inorganic materials such as plastic bags and plastic bottles from the feed inlet 210 into the collection container 14. The blade unit 23 includes a second flange 230 and a plurality of blades 231 fixed circumferentially on the second flange 230, and the second flange 230 is bolted to the first flange 26.

[0026] In some embodiments, the crushing unit 24 includes a third flange 241, at least two breaker hammers 243 and at least two cutting blades 244. The cutting blades 244 and the breaker hammers 243 are alternately distributed circumferentially on the same third flange 241. The third flange 241 is bolted to the first flange 26. The kitchen waste is crushed by the cutting blades 244 and the breaker hammers 243.

[0027] In some embodiments, the crushing unit 24 includes a third flange 241, a fourth flange 242, at least two breaker hammers 243 fixed on the third flange 241, and at least two cutting blades 244 fixed on the fourth flange 242. The third flange 241 and the fourth flange 242 are alternately distributed along the axis of rotation, and both the third flange 241 and the fourth flange 242 are bolted to the first flange 26.

[0028] The cutting blade 244 can cut long strips of food waste, further preventing them from getting tangled in the first rotating shaft 22.

[0029] In a preferred embodiment, the crushing unit 24 further includes at least two crushing plates 245. The crushing plates 245 and the cutting blade 244 are alternately distributed circumferentially on the same fourth flange 242. While crushing the kitchen waste, the crushing plates 245 can also act as blades to generate airflow towards the collection container 14. The outer circumferential surface of the crushing plates 245 facing the filter cylinder 21 is arc-shaped, and the crushing plates 245 can also scrape off the kitchen waste adhering to the inner wall of the filter cylinder 21.

[0030] Furthermore, the second flange 230, the third flange 241, and the fourth flange 242 are each provided with at least two second limiting slots spaced apart circumferentially. The second limiting slots correspond to the first slots, and the anti-winding plate 27 is disposed in the multiple second limiting slots and the first slots. Preferably, the upper end surface of the anti-winding plate 27 extends beyond the outer circumferential surface of the first flange 26, the second flange 230, the third flange 241, and the fourth flange 242, which facilitates the cutting blade 244 in cutting long strip-shaped objects in the kitchen waste and also facilitates the removal of long strip-shaped objects.

[0031] Furthermore, the filter cylinder 21 facing the discharge hopper 13 is provided with multiple filter holes 211. The kitchen waste crushed by the crushing unit 24 falls into the discharge hopper 13 through the filter holes 211, preventing uncrushed or incompletely crushed kitchen waste from falling into the discharge hopper 13. The aperture of the multiple filter holes 211 can be set to the same fixed value, or different values ​​can be set, that is, the aperture of the multiple filter holes 211 can be large or small.

[0032] The lower end of the discharge hopper 13 is provided with a discharge short pipe 5 that communicates with the discharge hopper 13. The end of the discharge short pipe 5 is provided with a fifth flange. The discharge short pipe 5 is connected to other conveying components through the fifth flange, so that the crushed organic kitchen waste is conveyed to gas equipment such as fermentation equipment for further processing through the conveying components.

[0033] In some embodiments, the food waste sorting and crushing machine further includes a discharge conveying assembly 6, which is used to automatically convey the crushed organic food waste out of the discharge short pipe 5, preventing food waste from accumulating in the discharge hopper 13 and the discharge short pipe 5. The discharge conveying assembly 6 includes a third rotating shaft 62 disposed in the discharge hopper 13 and the discharge short pipe 5, a second spiral plate 63 fixed on the third rotating shaft 62 and extending along the axial direction of the third rotating shaft 62, and a discharge motor 61 that drives the third rotating shaft 62 to rotate.

[0034] In some embodiments, the collection container 14 is used to collect inorganic kitchen waste. The collection container 14 has a receiving chamber that communicates with the filter cartridge 21, and a cleaning door is provided at the lower end of the collection container 14. When the collection container 14 is almost full of inorganic kitchen waste, the cleaning door can be opened to remove the inorganic kitchen waste from the receiving chamber.

[0035] Furthermore, the rotary motor 25 is located at the end of the collection container 14 away from the filter cylinder 21. Since the rotary motor 25 is located at the end far from the crushing unit 24, it ensures that the kitchen waste will not damage the rotary motor 25 when the crushing unit 24 is crushing the kitchen waste. Preferably, a protective isolation plate is also provided between the rotary motor 25 and the collection container 14 to prevent inorganic kitchen waste blown into the collection container 14 from damaging the rotary motor 25.

[0036] Furthermore, the conveying cylinder 31 has an inlet 310 facing the feed hopper 12. The screw conveying unit 33 includes a second rotating shaft 331 disposed inside the conveying cylinder 31, a first spiral plate 332 fixedly connected to the second rotating shaft 331 and extending along the axis of the conveying cylinder 31, and a conveying motor 333 that drives the second rotating shaft 331 to rotate. Kitchen waste enters the conveying cylinder 31 through the inlet 310 and is conveyed to the discharge limiting member 32 by the first spiral plate 332. The end of the conveying cylinder 31 away from the discharge limiting member 32 is sealed by a flange plate, and the conveying motor 333 is disposed at the end of the conveying cylinder 31 away from the discharge limiting member 32 and fixed to the flange plate by a motor mounting plate.

[0037] The material discharge limiting component 32 is used to ensure that all kitchen waste can fall into the filter cylinder 21 from the feed inlet 210. The material discharge limiting component 32 is connected to the filter cylinder 21 and the conveying cylinder 31 respectively. The material discharge limiting component 32 is provided with a material discharge channel and an inlet and an outlet connected to the material discharge channel. The inlet is directly opposite the cylinder channel of the conveying cylinder 31, and the outlet is directly opposite the feed inlet 210.

[0038] In some embodiments, the top of the feed hopper 12 is provided with an opening and closing cover 120, which is hinged to the feed hopper 12. Preferably, the kitchen waste sorting and crushing machine also includes a servo motor 8 for opening or closing the opening and closing cover 120.

[0039] In some embodiments, the food waste sorting and crushing machine also includes a material handling auxiliary component 7, which includes a transport track 71 fixed to the outer surface of the housing 11 and a support member 72 slidably connected to the transport track 71. The material handling auxiliary component 7 can help transport personnel transport the garbage bins containing food waste to the feed hopper 12.
