[0002] With the progress of society, the domestic catering industry has developed rapidly. Hot pot is a traditional and popular food in China. However, after people enjoy the hot pot residue, a large amount of residual material will be left at the bottom of the pot; this part of the hot pot residue is mainly a mixture of animal fat and water, and also includes a part of food residue. In the prior art: the hot pot shop needs to clean different hot pot basins at irregular times during business hours, but the material quality and temperature in each hot pot basin are different. In the process of treating hot pot residues, the existing equipment usually uses the method of continuously heating and dissolving oil to make oil and water separate naturally, which leads to a long time to realize oil-water separation, high energy consumption and inability to accurately separate oil and water. In order to meet the daily management of hot pot shops and the relevant regulations of the state on waste oil recycling and resource utilization, hot pot shops need to configure multiple devices to work synchronously, which causes high equipment cost and large equipment area. Therefore, how to develop a new type of high-efficiency hot pot residual oil-water separation device to overcome the above problems in the prior art is the direction that the technical personnel in the field need to research. SUMMARY

[0003] The present application aims to provide a hot pot residual oil-water separation device that can accurately separate oil and water, shorten the process time, and thus reduce equipment cost and equipment area.

[0006] By adopting the technical scheme: in the process of processing hot pot residues, the staff first pours the hot pot residues on the top of the box body of the static box, filters out the solid residues in the hot pot residues through the sieve hole, and at the same time, the oil-water mixture enters the static box through the sieve hole and merges with other oil-water mixtures previously poured to form a mixed liquid, at this time, the equipment obtains the temperature of the mixed liquid through the temperature measuring device, if the temperature is higher than 40 degrees, the first cooling device is started, if the temperature is lower than 40 degrees, the first heating device is started, so that the mixed liquid in the static box is always kept at about 40 degrees, when the oil-water mixture in the static box reaches the preset height, the first liquid level sensor opens the liquid outlet to guide the mixed liquid in the static box into the condensing box, at this time, the second liquid level sensor controls the liquid level height of the condensing box, and the second cooling device is started to cool and stratify the mixed liquid: the oil layer in the mixed liquid is solidified and floats on the upper side of the water layer, then the drain pipe is opened, and the water is first drained from the condensing box. Then the second cooling device and the drain pipe are closed; the oil outlet pipe is opened, and the second heating device is started, the solidified oil layer is dissolved into liquid state, and the liquid oil is guided from the oil outlet pipe into the oil collecting box. In the above process, since the temperature of the mixed liquid in the static box is kept basically constant, the working time of the second cooling device and the second heating device can be better grasped, so that the oil-water two-phase separation is realized with low energy consumption.
