Problems solved by technology

[0003] At present, most of the food waste pretreatment equipment will use electric energy, the equipment is relatively complicated, and the installation and manufacturing costs are high. The patent application number 201020109356.6 discloses a food waste pretreatment device. This device needs to be injected with clean water to process food waste. , increasing the amount of sewage generated, drying requires blasting and heating to waste a lot of electric energy
The patent with application number 201020272794.4 discloses a kitchen swill treatment machine. This patent only briefly introduces a recovery method without further process equipment, and the process consumes a lot of energy

Embodiment 1

[0019] Open the lid 2 of the 25L food waste pretreatment equipment, pour the food waste continuously to about 5cm from the bottom of the sieve-shaped steel drum, cover the lid 2 and turn the screw rod handle 1 to compress the food waste, and the oil and water will be in the gravity Under the action, it flows into the bottom of the barrel, and layers are formed at the bottom of the barrel due to different physical properties. When the oil layer is higher than the oil guide pipe 10, the waste oil flows into the waste oil collection tank through the oil guide pipe. When the height of the sewage layer reaches the oil guide pipe 10, the sewage starts Flow out from the oil guide pipe 10, and now the foot-operated drain 9 is opened, and the sewage is directly discharged into the sewer for unified treatment by the sewage treatment plant. Solid waste is collected and used as raw material for ethanol production, and waste oil is collected and used for biodiesel production.

Embodiment 2

[0021] Open the lid 2 of the 80L food waste pretreatment equipment, and when the food waste is continuously poured into about half the height of the sieve-shaped steel drum, cover the lid 2 and rotate the screw rod handle 1 to compress the food waste. After compression Open the bung 2 and continue to dump the kitchen waste to 5cm from the top of the sieve-shaped steel bucket, then compress it again, and the operation of its oil-water separation is the same as in Example 1.

Abstract

The invention relates to a simple pretreatment device for kitchen waste, which can easily and conveniently separate food waste into solid waste, waste oil and sewage without consuming energy. The pretreatment equipment can replace the currently used collection kitchen waste Ordinary garbage bins for garbage can reduce the use of plastic garbage bags. The invention uses geotextile bags for the first time to remove oil and water in kitchen waste, and the geotextile bags can be reused. This equipment has simple structure, convenient operation, no energy consumption, and can dehydrate food waste to meet the requirements of resource utilization, such as ethanol production, aerobic or anaerobic fermentation, etc.

Description

technical field [0001] The invention relates to a pretreatment device for kitchen waste, which can conveniently and quickly separate solid waste, oil and water contained in the kitchen waste without energy loss. Background technique [0002] Food waste is a relatively large part of urban waste, especially now that the catering service industry is developing rapidly, resulting in a large amount of food waste. Improper disposal can easily cause harsh environmental pollution. Some criminals directly feed pigs with food waste. Garbage pigs have caused serious food safety hazards. On the other hand, the organic matter content in kitchen waste is as high as 90%, which has great potential for resource utilization. It is an effective method of food waste treatment to realize the effective classification and collection of food waste at the source of food waste generation, and then collect the separated solid waste and waste oil for comprehensive treatment. [0003] At present, most ...
