Condensate-type oil-water separating device

Abstract

The invention discloses a condensate-type oil-water separating device. The condensate-type oil-water separating device is provided with a sealed machine case, a machine case cover plate, a control device and a drainage device. The side wall of the machine case is communicated with a sewage inlet pipe. The machine case is provided with a condensation oil extracting mechanism, an oil scraping mechanism, an oil removing mechanism and a refrigerating and heating system. Because the above structure is used, the condensate-type oil-water separating device has the advantages of novel structure, highautomation degree, great manpower and material resource conservation, high oil extracting efficiency, high oil outlet purity and the like.

Description

technical field [0001] The invention relates to the field of oily sewage separation equipment, in particular to a condensation type oil-water separation device. Background technique [0002] As we all know, in the food industry, with the rapid development of social economy and the continuous improvement of people's living standards, the catering industry has gradually flourished, and the problems of kitchen oily sewage treatment and sewage discharge have become increasingly prominent. Kitchen catering wastewater contains various impurities. Moreover, the waste water contains a large amount of oil. If it is discharged directly, it will have a negative impact on the drainage pipe network and the subsequent sewage treatment station. Therefore, it is necessary to carry out oil extraction treatment on the kitchen waste water to meet the "urban sewage into the sewer water quality" Discharge after the requirements of the Standard. [0003] In the industry, machining centers need t...

Problems solved by technology

[0003] In the industry, machining centers need to use coolant when machining workpieces. After the machining center has been working for a period of time, the temperature of the coolant will also increase. Due to the increase in the temperature of the coolant, the cooling effect is insufficient, thus It affects the processing quality of the workpiece. Therefore, the lubricating oil will be mixed with the cooling liquid during the working process of the machining center. Since the cooling liquid needs to be recycled, it is necessary to separate the cooling liquid and the lubricating oil. For example: CN 207286894 U is disclosed An oil-water separation cooling device, which includes a filter box, a separation box, an oil storage tank, an oil suction roller, an oil scraper and a motor, the filter box is arranged on the upper side of the separation box, and a filter plate is arranged between the filter box and the separation box , the side of the separation box away from the filter box is equipped with an oil suction roller, the oil suction roller is connected to the motor, one end of the oil scraper is against the oil suction roller, the other end of the oil scraper extends to the upper side of the oil storage tank, and a liquid separator is installed inside the separation box , a water pump is set in the middle of the liquid distribution pipe; the coolant will filter out the iron filings in the filter box, and the coolant will flow into the separation box from the upper side, and dissipate the heat in the process of flowing down from the top, and the oil suction roller will float in the coolant The lubricating oil in the oil absorbs and flows into the oil storage tank through the action of the oil scraper to complete the separation of oil and liquid

[0004] Therefore, the separation methods of the existing oil-water separation equipment can be roughly divided into gravity separation, centrifugal separation, electric separation, adsorption separation, air flotation separation, etc. These oil-water separation methods all have their own substantial defects, and the oil-water separation takes a long time. , low oil extraction efficiency, and low oil purity. If the gravity separation method adopts the form of a sedimentation tank, there will be a dead zone in the liquid flow. A large amount of odor is produced; the maintenance of power components of centrifugal separation equipment is difficult, and it is currently only used in laboratory analysis equipment, etc.

[0005] Moreover, due to the long residence time of the sewage and the separated oil in the oil-water separation equipment, the oil and water will rot and stink, resulting in odor and secondary pollution.

[0006] In addition, the separation of oil and water slag is not complete, resulting in poor oil quality and difficulty in storage and reuse
