[0001] The utility model relates to the technical field of biomass diesel, specifically to an oil -water separation device for biomass diesel based on waste oil. BACKGROUND

[0002] In the production process of biomass diesel, oil -water separation is a crucial link. Traditional oil -water separation methods often have problems such as low separation efficiency, complex operation, difficult maintenance, etc. These problems not only affect the production efficiency of biomass diesel, but also increase the production cost and environmental pollution risk.

[0003] Firstly, traditional oil -water separation methods usually rely on gravity sedimentation or chemical agents to achieve separation. However, these methods often cannot efficiently separate oil and water completely, resulting in a certain amount of water remaining in the separated oil, affecting the quality and stability of biomass diesel. At the same time, the use of chemical agents may also introduce new pollutants, causing secondary pollution to the environment.

[0004] Secondly, the structure of traditional oil -water separation equipment is complex and the operation is cumbersome. The maintenance and management of the equipment require professional knowledge and skills, increasing the labor cost and maintenance difficulty. In addition, the equipment occupies a large area, which is not suitable for biomass diesel production environments with limited space. INVENTION CONTENTS

[0008] Preferably, the buffer cover is in the shape of a circular truncated cone and is located between the cooling box and the flow guide block.

[0010] The utility model has the following beneficial effects:

[0016] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. EMBODIMENT

[0017] As Figure 1The utility model discloses an oil -water separation device for biomass diesel based on waste oil, including box 1, cooling tank 3, first motor 5 and second motor 9, the top of box 1 is provided with feed inlet 2, cooling tank 3 is fixedly connected in the inner top wall of box 1, the bottom of cooling tank 3 is provided with two discharge gates 4, and the inside of buffer cover 8 is fixedly connected with fixed bolster 7, and buffer cover 8 is located the just below of two discharge gates 4, and first motor 5 is fixedly connected in the bottom of cooling tank 3, and the drive end of first motor 5 is fixedly connected with drive rod 6, and the bottom of drive rod 6 is fixedly connected with fixed bolster 7, and second motor 9 is fixedly connected in the side wall of box 1, and the drive end of second motor 9 is fixedly connected with screw rod 10, and screw rod 10 is located in the inside of box 1, and one end of screw rod 10 is rotatably connected with the inner wall of box 1 away from second motor 9, and screw rod 10 is connected with flow guide block 11, and the front view shape of flow guide block 11 is isosceles trapezoid, and flow guide block 11 is located below the bottom opening of buffer cover 8, and the bottom of box 1 is provided with drain 12 and oil outlet 13.

[0018] The design that flow guide block 11 bottom is contacted with the inner bottom wall of box 1 can ensure that flow guide block 11 keeps stable during moving, and is not easy to sway or deviate. This design also helps to prevent water or oil from accumulating between flow guide block 11 and the bottom of the box, ensuring that water can be smoothly discharged from drain 12 and oil can be smoothly discharged from oil outlet 13.

[0019] The two side slopes of flow guide block 11 are located directly above drain 12 and oil outlet 13 respectively. The design that the two side slopes of flow guide block 11 are aligned with drain 12 and oil outlet 13 respectively can ensure that water and oil can flow directly into the corresponding outlets after separation, without forming a stagnant state in the box 1. This design helps to reduce energy loss during separation and improve separation efficiency.

[0020] The shape of buffer cover 8 is a circular truncated cone. The circular truncated cone-shaped buffer cover 8 can ensure that the waste oil can be evenly distributed on the cover wall when flowing in, thereby increasing the contact area between the oil and the cover wall and improving the oil-water separation effect. The circular truncated cone shape also helps to guide water and oil to flow in different directions, further promoting separation.

[0021] Buffer cover 8 is located between cooling tank 3 and flow guide block 11. The design of placing buffer cover 8 between cooling tank 3 and flow guide block 11 can ensure that the waste oil can immediately enter buffer cover 8 for preliminary separation after cooling, thereby reducing the residence time of waste oil in the box 1 and reducing the risk of re-mixing. This design also helps to keep the space between cooling tank 3 and flow guide block 11 clean, facilitating subsequent maintenance and cleaning.

[0022] The feed inlet 2 is installed on the top of the cooling box 3. The design of arranging the feed inlet 2 on the top of the cooling box 3 can ensure that the waste oil can directly flow into the cooling box 3 for cooling treatment, thereby reducing the residence time of the waste oil in the tank 1 and the risk of re-mixing. This design also helps to keep the feed inlet 2 clean and unobstructed, facilitating subsequent maintenance and cleaning.

[0023] Working principle: when using the waste oil-based biomass diesel oil-water separation device, the waste oil enters the cooling box 3 through the feed inlet 2. The cooling box 3 cools the waste oil to increase the oil viscosity. The cooled waste oil enters the inside of the tank 1 through the discharge outlet 4. After the waste oil enters the tank 1, it first flows onto the inner wall of the buffer cover 8. Due to the increased oil viscosity, the oil will stick to the inner wall of the buffer cover 8. The water in the waste oil flows to the bottom opening of the buffer cover 8 due to gravity. The first motor 5 drives the driving rod 6 to rotate, driving the fixed support 7 and the buffer cover 8 to rotate. The rotating buffer cover 8 makes the waste oil more fully contact with the inner wall, increasing the amount of residual waste oil on the inner wall. The water flowing out of the bottom opening of the buffer cover 8 flows onto the side wall slope of the flow guide block 11. The side wall slope of the flow guide block 11 guides the water to the drain 12. The water is discharged from the tank 1 through the drain 12. The second motor 9 drives the lead screw 10 to move linearly, moving the flow guide block 11 to a position corresponding to the oil discharge port 13. The oil on the inner wall of the buffer cover 8 slowly flows to the bottom opening thereof. The other side wall slope of the flow guide block 11 guides the oil to the oil discharge port 13. The oil is discharged from the tank 1 through the oil discharge port 13.

[0024] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
