Embodiment Construction

[0010] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] Such as figure 1 As shown, a method for harmless treatment of waste oil includes the following steps: the first step is to put the waste oil into a solid-liquid separator, and the impurities in the waste oil are extruded through solid-liquid separation; the second step is to The lifting pump lifts the waste grease treated by the solid-liquid separator to the heating oil storage tank for heating. When the liquid level of the heating oil storage tank reaches the preset position, the alarm system automatically sends out a beep signal to remind the valve to close; the third Step 1: When the waste oil is heated to 60 degrees Celsius in the heated oil storage tank, the alarm system will send out a buzzing signal to remin...

Abstract

The invention provides a waste grease innocent treatment method, comprising the steps of: firstly, putting waste grease into a solid-liquid separator to extrude out impurities in the waste grease by virtue of solid-liquid separation; then, lifting the treated waste grease into a heating oil storage tank to perform heating; next, heating the waste grease, and then naturally cooling the waste grease; then, discharging still waste oil into an outward transport package, discharging waste water by virtue of a pipe valve arranged at the lower end of the heating oil storage tank, and discharging waste residues into a stirring machine by virtue of the pipe valve; next, adding saw powder into the waste residues, performing stirring, and then discharging the waste residues into a second solid-liquid separator to perform solid-liquid separation; and finally, discharging solids, obtained after separation, by virtue of an outlet, and lifting liquid to the heating oil storage tank to perform cycle treatment. The invention also provides equipment used for the waste grease innocent treatment method to implement this type of treatment method.

Description

technical field [0001] The invention belongs to the technical field of utilization of waste oil, and in particular relates to a method for harmless treatment of waste oil; the invention also relates to equipment for treating waste oil. Background technique [0002] Waste oils and fats refer to animal and vegetable oils that are no longer edible and are produced during production and operation. According to their sources, they can usually be divided into gutter oil, swill oil and frying oil. [0003] Waste oil is often mixed with a large amount of harmful substances such as sewage, garbage, bacteria, etc. Some of them have been repeatedly fried and cooked, and contain a large amount of carcinogens such as aflatoxin, which seriously endanger people's health. In recent years, with the continuous improvement of people's living standards, the catering service industry has developed rapidly, and the output of waste edible oils is increasing day by day. How to dispose and supervise...
