Problems solved by technology

The crushing and direct discharge method is only suitable for units with a small output of kitchen waste. It is easy to generate sewage and odor during treatment, which breeds germs, mosquitoes and flies, and causes the spread of diseases. The condensation of oil into blocks will cause blockage of drain pipes and reduce the drainage of urban sewers. ability
The cost of biological treatment is high, and it is not suitable for the treatment of moldy, severely deteriorated and chemically polluted kitchen waste, so as not to contaminate downstream products
The kitchen waste made into feed cannot deteriorate, and it is necessary to classify the kitchen waste. Since the kitchen waste is mixed with various impurities (table paper, chopsticks, disposable tablecloths, etc.), sorting is difficult
In short, the existing kitchen waste treatment technology has its limitations, and the degree of resource utilization is not high

Embodiment 1

[0018] 1) Take 500g of kitchen waste and put it in a constant temperature drying oven after cutting, mixing and simple treatment, and keep it at 105±1°C for 10 hours. After the kitchen waste is dried, it is crushed into a size of 3-5mm.

[0019] 2) Put the dried garbage in a ceramic cup and carbonize it in a high-temperature nitrogen protection furnace. Keep the furnace pressure at 0.10-0.15MPa, start heating from room temperature, control the temperature rise rate at 2°C / min, keep it for 20 minutes when the temperature rises to 120°C, then raise the temperature to 600°C at 1°C / min, and keep at 600°C for 80 minutes minute. Finally, let it cool down to room temperature naturally to make porous carbonized material.

[0020] 3) Grinding the charcoal into a size of 1-2 mm, then mixing 40% of the porous charcoal, 10% of stearic acid, 25% of PVC (polyvinyl chloride) resin powder, and 25% of epoxy vinyl resin, and then uniformly stirred and ultrasonically Vortex to mix the mixture...

Embodiment 2

[0022] 1) Take 500g of kitchen waste, shred it, mix it briefly, put it in a constant temperature drying oven, and keep it at 105±1°C for 11 hours. After the kitchen waste is dried, it is crushed into a size of 3-5mm.

[0023] 2) Put the dried garbage in a ceramic cup and carbonize it in a high-temperature nitrogen protection furnace. Keep the furnace pressure at 0.10-0.15MPa, start heating from room temperature, control the heating rate at 3°C / min, keep it for 15 minutes when the temperature rises to 140°C, then raise the temperature to 700°C at 1.6°C / min, and keep at 700°C for 70 minutes minute. Finally, let it cool down to room temperature naturally to make porous carbonized material.

[0024] 3) Grinding the charcoal into a size of 1-2 mm, then mixing 30% of the porous charcoal, 30% of stearic acid, 20% of PVC resin powder, and 20% of epoxy vinyl resin, and thoroughly mixing the mixture through uniform stirring and ultrasonic vibration . After the vibration is over, pla...

Embodiment 3

[0026] 1) Take 500g of kitchen waste, shred it, mix it briefly, put it in a constant temperature drying oven, and keep it at (105±1)°C for 12 hours. After the kitchen waste is dried, it is crushed into a size of 3-5mm.

[0027] 2) Put the dried garbage in a ceramic cup and carbonize it in a high-temperature nitrogen protection furnace. Keep the furnace pressure at 0.10-0.15MPa, start heating from room temperature, control the heating rate at 2.5°C / min, keep it for 17min when the temperature rises to 150°C, then raise the temperature to 800°C at 2°C / min, and keep at 800°C for 60 minutes minute. Finally, let it cool down to room temperature naturally to make porous carbonized material.

[0028] 3) Grinding the charcoal into a size of 1-2 mm, then mixing 35% of the porous charcoal, 20% of stearic acid, 22% of PVC resin powder, and 23% of epoxy vinyl resin, and the mixture is fully mixed through uniform stirring and ultrasonic vibration . After the vibration is over, place the...

Abstract

The invention discloses a sound-absorbing ceramic plate using kitchen waste as raw material and preparation method thereof. Through a drying process, organic matter of kitchen solid waste ecological material are used as raw material, charring in a high temperature nitrogen protective stove to form porosint. Smashing charring matter then adding with pore forming agent such as eleaostearic acid, oxene resin and PVC resin powder, the mixture is mixed fully through uniform stirring and supersonic wave oscillation. After oscillation, the mixture material is filled in a molding cavity under pressure, then putting into an oven to cure; a sound-absorbing ceramic plate is got after natural cooling. The preparation technology of the invention is simple, has low cost, raw material is kitchen waste, can get harmless rubbish with decrement, resource treatment when getting sound-absorbing ceramic plates. The sound-absorbing ceramic plate can be applied to construction business and decoration field.

Description

technical field [0001] The invention relates to solid waste treatment, in particular to a sound-absorbing ceramic plate made of kitchen waste and a preparation method thereof. Background technique [0002] In today's society, environmental problems are becoming more and more prominent, and the problem of resource shortage is also becoming more and more serious. How to turn waste into wealth and recycle resources has attracted the attention of all walks of life. [0003] Kitchen waste includes various organic wastes such as leftovers, leftovers, vegetable leaves, fruit peels and packaging bags, which account for about 30% to 40% of domestic waste. Kitchen waste is rich in nutrients and used to be a good feed for pigs, but it is likely to contain pathogenic microorganisms if it is not treated. After the publication of the document "Forbidden to use swill to feed pigs", the utilization of resources has become the key. [0004] At present, the main treatment methods of kitche...
