Background

In recent years, with the rapid development of economy in China, various fried foods are popular among people due to convenience, good taste and time saving, and the amount of waste edible oil generated is continuously increased. When the fried food is processed and prepared, the vegetable oil is fried at high temperature and repeatedly used, the grease is oxidized at high temperature, and simultaneously, the water in the food can be subjected to hydrolysis reaction with the grease, so that the color of the food is darkened, the viscosity of the food is increased, bubbles are continuously formed, and the grease is deteriorated. The unsaturated fatty acids and vitamins of the deteriorated oil are all destroyed, and a large amount of toxic substances such as acrolein and the like are generated through polymerization.

In China, the catering industry is a main source for producing waste oil. At present, the catering industry in China uses millions of tons of oil every year, and if the problem of waste oil cannot be solved, serious environmental pollution can be caused.

Further, the centrifugal tank comprises a hollow oil guide rotating shaft, and a centrifugal cover coaxial with the oil guide rotating shaft is further arranged in the centrifugal tank.

Furthermore, the oil guide rotating shaft is provided with an oil guide hole.

Furthermore, a baffle is surrounded on the outer side of the filtering cloth bag and extends to the same horizontal plane with the bottom end of the filtering cloth bag.

Furthermore, a filtering screen is arranged at the top end of the recovery barrel.

Furthermore, the adding amount of the activated clay is 5% of the oil amount of the waste oil to be purified.

Therefore, compared with the prior art, the waste oil purifying and recycling device mainly has the following advantages: the utility model discloses can be effectively, purify abandonment edible oil in large batch, because the existence of centrifugation jar for oil water separation is more thorough, and it is higher that the waste oil cleanliness after the purification is, can reuse more effectively.

Fig. 2 is a schematic view of the structure of the oil guiding rotating shaft of the present invention.

Wherein: 1. the device comprises a water purifying pool, 2 a degumming tank, 21 an oil collecting funnel, 22 a heater, 3 a filtering cloth bag, 4 a baffle, 5 a centrifugal tank, 51 an oil guide rotating shaft, 52 a centrifugal cover, 53 an oil guide hole, 6 an alkaline washing and decoloring pool, 7 a recycling bin and 71 a filtering screen.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to assist in understanding the embodiments of the invention defined by the claims. It includes various specific details to assist understanding, but they are to be construed as merely illustrative. Accordingly, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Also, in order to make the description clearer and simpler, a detailed description of functions and configurations well known in the art will be omitted. As used in the description, the terms "front," "back," "left," "right," "up," and "down" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The invention will be further described with reference to the following several drawings: referring to fig. 1, the waste oil purification and reuse device comprises a water purification tank 1, a degumming tank 2, a centrifugal tank 5, an alkaline washing and decoloring tank 6 and a recycling bin 7. The water purifying tank 1 is communicated with the degumming tank 2 through a water pump, and the bottom of the degumming tank 2 is provided with a heater 22. The water in the water purifying pool is pumped into a degumming tank 2, the top of the degumming tank 2 is provided with a hole, an oil collecting funnel 21 is arranged on the hole, the upper end of the oil collecting funnel 21 is correspondingly provided with a filter cloth bag 3, the outer side of the filter cloth bag 3 is surrounded with a baffle 4, and the baffle 4 extends to the same horizontal plane with the bottom end of the filter cloth bag 3. The baffle 4 prevents the waste oil from leaking out of the oil collecting hopper 21. After the waste edible oil is primarily filtered by the filter cloth bag 3, the waste edible oil flows into the degumming tank 2 through the oil collecting funnel 21 at the top of the degumming tank 2, and because the waste edible oil contains a large amount of hydrophilic phospholipid, the hydrophilic phospholipid absorbs water to expand and coagulate into colloid at the water bath temperature of 70-80 ℃, and the colloid forms hydrate with larger relative oil density. The other side of the degumming tank 2 is communicated with a centrifugal tank 5 through a pipeline. The centrifugal tank 5 comprises a hollow oil guide rotating shaft 51, a centrifugal cover 52 coaxial with the oil guide rotating shaft 51 is further arranged in the centrifugal tank 5, and an oil guide hole 53 is formed in the oil guide rotating shaft 51. The waste edible oil after being fully degummed in the degummed tank 2 is subjected to the centrifugal action in the centrifugal tank 5, and then the oil and the water are thoroughly separated. The oil guide hole 53 is connected to an alkaline washing and decoloring tank 6 filled with caustic soda and activated clay through a pipeline. And the waste oil after oil-water separation enters an alkaline washing and decoloring pool 6 for neutralization and decoloring, and the adding amount of the activated clay is 5% of the oil amount of the waste oil to be purified. The usage of the activated clay is more suitable when the usage amount is 5 percent of the required purification waste oil amount, and when the usage amount exceeds 5 percent, the decolorization effect is not greatly changed when the usage amount is more than 5 percent. The alkali washing and decoloring tank 6 pumps the purified waste oil into the recycling bin 7 through an oil pump, the top end of the recycling bin is provided with a filter screen 71, and the filter screen 71 can filter activated clay and flocculates, so that secondary filtering operation is omitted.
