Method and device for treating kitchen waste

Abstract

The invention discloses a processing method and device for kitchen waste. In this method, the food waste is poured into the slag collection grid of the sorting collection device, and a slag discharge port is provided on one side of the slag collection grid; The oil and water flow into the oil collection grid under the classification collection device through the filter screen, and the oil collection grid is connected with the oil storage tank through the oil suction pipe; The height controls the height of the liquid level in the oil collecting grid, and at the same time, the excess water in the overflow grid is discharged through the overflow port. The invention can ensure the relative purity of oil-water separation, moderate oil pumping speed by adopting negative pressure, stable change of oil layers, and no clogging of the pump. Automatic control by single-chip microcomputer can trace the whereabouts of oil, so as to realize effective control of waste oil production. The invention has fine and reasonable design, small volume, high efficiency and good trial effect for users.

Description

technical field [0001] The invention relates to a treatment method and device for kitchen waste, belonging to the technical field of kitchen waste treatment. Background technique [0002] For a long time, in the development of food waste treatment equipment, the oil-water separation mainly uses the collected oil-water mixture to stand and then stratify, judge the oil-water stratification by human observation, and separate the stratified water in the oil-water separator. The effect of oil-water separation is achieved by releasing or oil releasing. This method has some major defects: firstly, the layout of the oil-water separation box makes the oil-water sedimentation and stratification unsatisfactory; secondly, after the oil-water natural sedimentation and stratification, the water and oil discharge need to be manually observed and controlled, which makes the operation and management difficult. Trouble, the automation of the separation system is very low. This greatly affec...

Problems solved by technology

This method has some major defects: firstly, the layout of the oil-water separation box makes the oil-water sedimentation and stratification unsatisfactory; secondly, after the oil-water natural sedimentation and stratification, the water and oil discharge need to be manually observed and controlled, which makes the operation and management difficult. Trouble, very little automation of the separation system

Thirdly, when the oil is extracted after the oil-water separation is completed, the quantity and whereabouts of the extracted oil cannot be effectively controlled, so that some of the collected oil is illegally processed and used
