Description

Technical Field

[0001] The utility model belongs to the field of environmental protection devices, and in particular relates to a kitchen waste sorting, crushing and squeezing machine. Background Art

[0002] Kitchen waste refers to organic waste generated in daily life and in food processing, catering services, corporate catering and other activities. These wastes usually include leftovers, fruit peels, vegetable leaves, bones, grease, etc. Due to its high water content and perishable characteristics, kitchen waste needs to be effectively treated and managed.

[0003] The main characteristics of food waste: 1. High moisture content: the moisture content of food waste is usually between 60% and 90%; 2. High organic matter content: including carbohydrates, proteins, fats, etc., which are easy to rot and ferment; 3. Easy to rot: at room temperature, food waste is easy to ferment, produce odor and harmful microorganisms; 4. Strong miscellaneousness: food waste may contain non-degradable impurities such as plastic, metal, glass, etc.

[0004] Difficulties in the treatment of food waste: 1. Environmental pollution: Untreated food waste will release greenhouse gases such as methane, pollute the environment, and may also pollute water sources and soil; 2. Sanitation issues: Rotting food waste will attract mosquitoes and rodents and spread diseases; 3. Waste of resources: If a large amount of organic matter is not processed as a resource, it will waste potential energy and fertilizer resources.

[0005] Common methods for treating food waste at present: 1. Composting: aerobic composting of food waste to generate organic fertilizer for agriculture or gardening. Composting can effectively reduce the volume of waste and generate high-value fertilizer; 2. Anaerobic fermentation: fermentation under anaerobic conditions to generate biogas (mainly methane) and biogas residue. Biogas can be used for power generation or as fuel, and biogas residue can be used as fertilizer; 3. Animal feed processing: food waste is processed into animal feed through high-temperature treatment, and the processing process must be strictly controlled to prevent the spread of pathogens; 4. Incineration: food waste is incinerated at high temperature to generate heat energy. Although the amount of waste can be reduced, the incineration process may produce harmful gases, and an efficient flue gas purification device is required; 5. Automatic sorting, crushing and squeezing: This method integrates sorting, crushing and squeezing, and uses physical means to classify, crush and dehydrate the waste, which is convenient for subsequent treatment or direct resource utilization.

[0006] Although there are some kitchen waste crushing and squeezing processing devices at present, these processing devices cannot effectively separate solids and liquids during sorting and crushing, so that the separated solids are still mixed with a large amount of liquid components, and the waste treatment cannot be effectively completed.

The side wall of the first main shaft 8 is provided with feeding blades 11, a cutter disc 13 and a discharging fan 18 from left to right in sequence. The straight hammer 14 and the oblique hammer 16 are arranged between adjacent cutter discs 13. The first main shaft 8 will drive the rotation of the feeding blades 11, the cutter disc 13 and the discharging fan 18, thereby The first main shaft 8 can transport the garbage to the inside of the first shell 6 through the feeding blades 11, and then effectively separate the kitchen waste once through the straight hammers 14 and the oblique hammers 16 between the adjacent cutter discs 13; the sorting screen 12 is arranged along the side wall of the first main shaft 8, and the two side ends of the sorting screen 12 are connected to the inner wall of the first shell 6.

[0038] The second shell 7 is provided with an inspection port 25, a solid residue outlet 24 and a water receiving trough 20. The inspection port 25 is provided on the side wall of the second shell 7 where the first shell 6 and the second shell 7 are connected. When the second main shaft 15 is heard to be idling or when it is found that there is an obvious excessive accumulation of food waste in the crushing device, the squeezing reduction motor 10 can be turned off and then repaired through the inspection port 25; the solid residue outlet 24 is provided at the second end of the second shell 7, and the solid residue outlet 24 is below the spring 22. The water receiving trough 20 is located at the lowest point of the second shell 7 installed behind the bracket 5, so that the separated liquid can be collected in the water receiving trough 20. A liquid discharge port is provided on the water receiving trough 20, and the liquid discharge port is used to discharge the collected liquid.

[0039] The sieve opening diameter of the sorting screen 12 is larger than that of the pressing screen 17 , so that the sorting screen 12 can pass the solid-liquid mixture, while the pressing screen 17 prevents solid matter from entering the water receiving tank 20 as much as possible.

[0040] When working:

[0041] The driving motor 3 and the second pulley 1 rotate, and the belt will drive the first pulley 4 to rotate the first main shaft 8. When the food waste enters from the feed port 9, the feeding blade 11 rotates at a high speed to propel the food waste forward in a spiral and generate axial wind. When the waste reaches the crushing area, the multiple groups of straight hammers 14 on the cutter disc 13 rotate at a high speed in the circumferential direction to hammer the material to break up the large pieces of organic waste in the food waste, and grind them into a slurry of a specific size with the cooperation of the sorting screen 12. The broken organic waste passes through the sorting screen 12 and enters the pressing link. Bottle caps, chopsticks, plastic bags and plastic bottles will not be beaten into particles, and continue to be pushed forward under the action of the axial wind and the oblique hammer 16, and are finally blown out through the screen outlet 19 by the circumferential wind generated by the fan.

[0042] The second main shaft 15 rotates with the rotation of the squeezing motor reducer. After the crushed organic waste enters, it is spirally squeezed and pushed forward under the structure of the spiral blade 26. As the distance between the blades gradually decreases and the diameter of the second main shaft 15 gradually increases, the space where the material is located gradually decreases. At the same time, under the action of the squeezing head 21 and the spring 22, the pressure on the wet waste gradually increases, so that the water is squeezed out through the squeezing screen 17. When the spiral pressure on the waste is greater than the elastic force of the spring 22, the spring 22 is automatically squeezed, and the solid residue is squeezed out and finally discharged through the solid residue outlet 24. The squeezed wastewater enters the water receiving tank 20 and is discharged through the drain port.

[0043] The embodiments described above are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
