Description

Technical Field

[0001] The utility model relates to the technical field of biodiesel production equipment, and more specifically, to a glycerol separation device for biodiesel production. Background Art

[0002] Biodiesel refers to fatty acid methyl esters or ethyl esters formed by esterification of vegetable oil, animal oil, waste oil or microbial oil with methanol or ethanol. Biodiesel is a typical "green energy" with good environmental performance, good engine starting performance, good fuel performance, wide source of raw materials, and renewable characteristics. Glycerin needs to be separated during the production of biodiesel, but the traditional separation method uses a single method to completely separate glycerin. The equipment used in the above separation method is complex, costly, and has low separation efficiency.

[0003] After searching, a Chinese patent with publication number CN215026227U discloses a glycerin separation device in a biodiesel production process. The glycerin separation device in a biodiesel production process separates water and glycerin through centrifugal action. When the centrifugal blades stop rotating, the glycerin floats up and can be discharged after the solenoid valve is opened. The upper glycerin can be more fully discharged with the assistance of an oil scraper pull ring. After the glycerin is discharged, a certain amount of water at the bottom is discharged and then the glycerin mixture is injected again. The above operation is repeated to achieve the preliminary separation of glycerin and improve the utilization efficiency of the device.

[0004] However, in actual use, since the device needs to put glycerol into a barrel when separating glycerol, the glycerol barrel needs to be placed on the top of the separation barrel to separate the glycerol. However, in the biodiesel production process, glycerol is produced continuously, and separating the glycerol by barreling consumes a lot of time and manpower, resulting in low work efficiency. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a glycerol separation device for biodiesel production to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a glycerol separation device for biodiesel production, comprising an outer shell, a support column is provided at the bottom of the outer shell, a water inlet is provided on one side of the outer shell, a drain port is provided at the bottom of the outer shell, an oil drain port is provided on one side of the outer shell, a water storage tank is provided inside the outer shell, an oil drain tank is provided on the top of the water storage tank, and an auxiliary oil scraping assembly is provided inside the oil drain tank.

[0007] Preferably, the auxiliary oil scraper assembly includes a rotating shaft, which is arranged inside the oil drain bin, the number of the rotating shafts is set to two, a rubber belt is provided on the outside of the rotating shaft, a scraper is connected to the outside of the rubber belt, the number of the scrapers is set to several, one end of one of the rotating shafts is provided with a drive motor, and the output end of the drive motor is coaxially connected to one of the rotating shafts.

[0008] Through the above scheme, it can be seen that by setting a water inlet on the outside of the shell, the water-oil mixture is continuously discharged into the water storage tank inside the shell through the water inlet. At this time, the servo motor is started, and the servo motor drives the stirring plate to stir, and then the water-oil stratification is realized by utilizing the different densities of water and oil. As the water-oil mixture continuously enters the water storage tank, the oil layer continuously floats to the top of the water layer. At this time, the drive motor is started, and the motor drives the rotating shaft to rotate, and then the rotating shaft drives the rubber belt to rotate, and the rubber belt drives the scraper to push the oil layer. At this time, the oil layer is discharged through the oil discharge port under the action of the scraper, and then the drain port at the bottom of the shell is opened to discharge the sewage inside the water storage tank, so that oil and water can be discharged simultaneously, thereby improving the practicability of the device.

[0009] Preferably, a servo motor is provided at the bottom of the shell, and the output end of the servo motor is connected to a stirring plate, and the bottom surface of the stirring plate is coaxially connected to the output end of the servo motor; an inclined slope is provided inside the oil drain bin, and the cross-sectional shape of the oil drain bin is set to a rectangle; a sliding protective cover is provided on the top of the oil drain bin, and a limiting protrusion is provided on the bottom of the sliding protective cover, and the number of the limiting protrusions is set to three; a limiting card slot is provided on the surface of the oil drain bin, and the number of the limiting card slots is set to three, and the limiting card slot is adapted to be engaged with the limiting protrusion; a placement slot is provided on the top of the oil drain bin, and a limiting block is provided on one side of the shell, and one end of the limiting block is rotatably connected to the shell.

[0010] Through the above scheme, it can be seen that a stirring plate is installed inside the water storage tank, and then the stirring plate is driven by a servo motor to stir the water-oil mixture inside the water storage tank, and then the speed of water-oil stratification is accelerated by centrifugal force, thereby improving the speed of the water-oil separation process and improving the overall work efficiency.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting up an auxiliary oil scraping component, compared with the prior art, a water inlet is set on the outside of the shell, and the water-oil mixture is continuously discharged into the water storage tank inside the shell through the water inlet. At this time, the servo motor is started, and the stirring plate is driven by the servo motor to stir, and then the water-oil stratification is realized by utilizing the different densities of water and oil. As the water-oil mixture continuously enters the water storage tank, the oil layer continuously floats to the top of the water layer. At this time, the driving motor is started, and the motor drives the rotating shaft to rotate, and then the rotating shaft drives the rubber belt to rotate, and the rubber belt drives the scraper to push the oil layer. At this time, the oil layer is discharged through the oil discharge port under the action of the scraper, and then the drain port at the bottom of the shell is opened to discharge the sewage inside the water storage tank, so that the oil and water can be discharged at the same time, thereby improving the practicality of the device;

[0013] 2. By setting up a stirring plate, a stirring plate is installed inside the water storage tank, and then the stirring plate is driven by a servo motor to stir the water-oil mixture inside the water storage tank, and then the speed of water-oil stratification is accelerated by centrifugal force, thereby improving the speed of the water-oil separation process and improving the overall work efficiency.
