Description

Technical Field

[0001] The utility model relates to the technical field of combustion devices, in particular to a waste oil combustion device with an automatic oil control function. Background Art

[0002] With the progress of modern agriculture, the number of agricultural machinery in my country has increased significantly, and the use of engine oil is also increasing. As a result, the amount of waste engine oil in rural areas is increasing. In the vast rural areas, due to the long distance and high cost, most farmers will replace the waste engine oil in the agricultural machinery by themselves, which leads to farmers choosing to abandon the waste engine oil because it cannot be effectively treated, which will cause environmental pollution. Due to the chemical properties of the waste engine oil itself, if there is no large amount of air to assist combustion during combustion, a large amount of black smoke and harmful substances will be produced due to incomplete combustion. Therefore, few people use it for heating or as a combustion aid. There is also a large tradition of making fried foods in rural areas, which will produce a large amount of "cooked oil". As the concept of health is deeply rooted in people's hearts, these "cooked oils" will also be abandoned. Therefore, waste oil furnaces came into being.

[0003] The existing waste oil furnace generally adopts manual control of the refueling speed, which will have the following problems: if the oil consumption rate of the waste oil furnace is greater than the oil feeding rate during combustion, it will be extinguished due to lack of oil; if the oil consumption rate of the waste oil furnace is less than the oil feeding rate during combustion, the oil level in the waste oil furnace will rise, which may exceed the fire core and cause the flame to go out or even overflow from the furnace body; therefore, a waste oil combustion device with automatic oil control function is provided to solve the above problems.
