Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste grease processing equipment, in particular to a waste grease preprocessing device. Background Art
[0002] Waste cooking oil is the main source of raw materials for the production of biomass fuel. At the beginning of the production of biomass fuel, waste cooking oil needs to be pre-treated, that is, sedimentation and filtration to remove water, impurities, and colloids before it can become the raw material oil for biomass fuel.
[0003] When the existing waste oil pretreatment method treats the acidified waste oil in the waste animal and plant oils, the inner wall of the treatment tank will be covered with grease. Although some pretreatment tanks may be equipped with scrapers to scrape off the grease attached to the inner wall of the pretreatment tank, although this method scrapes off the grease attached to the inner wall of the pretreatment tank to a certain extent, the cleaning effect is not good. If the pretreatment tank is left unused for a long time, the grease remaining on the inner wall of the tank that is not scraped clean by the scraper will still produce odor, pollute the environment, and affect the next use. Therefore, a new type of waste grease pretreatment device is specially designed. Utility Model Content

DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.
[0014] like Figure 1 As shown, a waste grease pretreatment device comprises a pretreatment tank 8, a liquid inlet is provided on one side of the pretreatment tank 8, and a liquid outlet is provided on the other side, wherein the liquid inlet is connected to a booster pump 7 through a pipeline, and the inlet of the booster pump 7 is connected to a cleaning water storage tank 1 through a liquid inlet pipe 3, and an electric valve 2 is provided on the end of the liquid inlet pipe 3 close to the cleaning water storage tank 1, in order to prevent the cleaning agent from flowing back to the cleaning water storage tank 1, the electric valve 2 adopts a check valve; the end close to the booster pump 7 is connected to a cleaning agent inlet pipe 4, the cleaning agent inlet pipe 4 is connected to the cleaning agent storage tank 6, and the cleaning agent inlet pipe 4 is provided with a solenoid valve 5; the liquid outlet is connected to a wastewater recovery and treatment system through a pipeline; an electric heater 10 is also provided in the pretreatment tank 8, and in order to accelerate the dissolution of grease, a stirring structure is provided on the top of the pretreatment tank 8, and the stirring structure comprises a stirring motor 9 installed on the top of the pretreatment tank 8, a stirring shaft 91 and a stirring blade 92 installed inside the pretreatment tank 8, wherein the output shaft of the stirring motor 9 is connected to the stirring shaft 91, and the stirring blade 92 is fixed on the stirring shaft 91. A temperature sensor 11 is also provided in the pretreatment tank 8 .
[0015] The device also includes a controller, which is respectively connected to the temperature sensor 11, the electric heater 10, the booster pump 7, the electric valve 2, the solenoid valve 5 and the stirring motor 9.
[0016] When the pretreatment tank 8 is initially cleaned, the electric valve 2 and the solenoid valve 5 are opened, and the booster pump 7 is started. The booster pump 7 sucks the cleaning water and the cleaning agent. Since the liquid inflow of the cleaning water and the liquid inflow of the cleaning agent are different, the opening time of the electric valve 2 and the solenoid valve 5 is controlled by the controller, and the cleaning water and the cleaning agent are mixed and enter the pretreatment tank 8. At this time, the electric heater 10 in the pretreatment tank 8 heats the mixed liquid, and the stirring motor 9 stirs so that the mixed liquid cleans the pretreatment tank 8. After the cleaning is completed, the cleaning mixed liquid is discharged to the wastewater recovery and treatment system through the liquid outlet; after the initial cleaning is completed, a secondary cleaning is performed. During the secondary cleaning, only the electric valve 2 is opened. At this time, the booster pump 7 sucks the cleaning water into the pretreatment tank 8, and the electric heater 10 heats the cleaning water, and stirs it through the stirring structure for secondary cleaning. After cleaning, the cleaning water is discharged to the wastewater recovery and treatment system.
[0017] The temperature sensor 11 monitors the temperature in the pretreatment tank 8, and the temperature transmits a signal to the controller, which controls the electric heater 10 according to the temperature. If the temperature is too high, the electric heating is stopped. The purpose of heating is to make the grease attached to the inner wall of the pretreatment tank 8 easier to dissolve when cleaning the mixed liquid.
[0018] The purpose of the first cleaning is to dissolve the grease in the cleaning mixture and discharge it, and the purpose of the second cleaning is to clean the cleaning mixture remaining on the pre-treated inner wall to make the cleaning more thorough.
[0019] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art.
