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

Embodiment

[0025] The present invention mainly includes three parts: classification collection device 1, oil storage tank 9 and control circuit. The optimal design for the classification collection device 1 is to set the slag collection grid 2, the oil collection grid 7 and the overflow grid 10 in the classification collection device box to effectively separate the impurities, oil and water in the kitchen waste. The specific structure is as figure 1 shown. Food waste is a mixture of oil, water and slag. The mixture of oil, water and slag is poured into the classification collection device 1 from the slag collection grid 2, and is relatively static and separated in the slag collection grid 2. The oil and part of the water enter the oil collection grid 7 . The slag in the slag collecting grid 2 can be directly discharged from the slag discharge port. The oil collecting grid 7 and the overflowing grid 10 adopt the principle of a connecting device, and the bottom is connected. The oil ...

Abstract

The invention discloses a kitchen waste treatment method and device. According to the method, kitchen waste is poured into residue collection grid of a classified collecting device, and one side of the residue collection grid is provided with a residue discharge port; impurities in the kitchen waste are filtered out by a filter screen disposed at the bottom of the residue collection grid; oil and water in the kitchen waste flow into an oil collection grid below the classified collecting device through the filter screen, and the oil collection grid is connected to an oil storage tank through an oil pumping pipe; the bottom of the oil collection grid is communicated with an overflow grid equipped with an overflow port, the height of liquid in the oil collection grid is controlled by setting the height of the overflow port, and at the same time redundant water in the overflow grid is discharged through the overflow port. The method and the device provided by the invention ensure relative purity of oil-water separation, and by employing negative pressure oil pumping, the speed is moderate, the oil layer change is smooth, and the pump cannot be blocked. Automatic control is carried out by a single chip microcomputer, and whereabouts of oil can be traced, thus realizing effective control of illegal cooking oil production. The device provided by the invention has the characteristics of exquisite and reasonable design, small volume, high efficiency, and good user trial effect.

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...
