Description

Technical Field

[0001] This utility model relates to the technical field of mixing equipment for No. 4 biodiesel and reagents, and particularly to a rapid mixing device for No. 4 biodiesel. Background Technology

[0002] Biodiesel is primarily composed of fatty acid methyl esters produced by the reaction of waste animal and vegetable oils with methanol. As a secondary product of biodiesel production, No. 4 biodiesel, compared to primary products like No. 2 and No. 3 biodiesel, is characterized by higher kinematic viscosity, poorer fluidity, and higher sulfur content. Therefore, when selling No. 4 biodiesel, it is typically processed to reduce its kinematic viscosity and sulfur content according to different customer requirements. Currently, the common method for mixing No. 4 biodiesel with reagents involves directly adding the reagent to the tank via a pipeline and then agitating it under pneumatic pressure. This method has two drawbacks: firstly, directly adding the reagent through a pipeline can cause excessively high local reagent concentrations within the mixing tank, which can easily lead to other reactions; secondly, pneumatic agitation is difficult to achieve uniform mixing or requires a long agitation time. Therefore, it is necessary to develop a rapid oil-solvent mixing device for No. 4 biodiesel that can uniformly and quickly add reagents and mix them evenly with the oil. Summary of the Invention

[0003] The purpose of this invention is to provide a rapid mixing device for No. 4 biodiesel oil that allows for quick and uniform mixing of oil and reagents, minimizes the occurrence of other reactions, and is highly efficient and reliable in operation. This solves the problems in the prior art where adding reagents directly into the tank through a pipeline and stirring with compressed air results in excessively high local reagent concentrations leading to other reactions, insufficient mixing, and long mixing times.

[0004] To achieve the above objectives, the present invention provides a rapid mixing device for No. 4 biodiesel, comprising a mixing tank 1, a reagent pressurizing tank 2, a reagent spray pipe 3, a reagent nozzle 5, a stirring paddle 6, a stirring motor 7, a feeding pump 8, a No. 4 biodiesel feed valve 9, a reagent feed valve 10, a reagent pressurizing tank discharge valve 11, a mixing tank discharge valve 12, and a post-pump valve 13. The upper side of the reagent pressurizing tank 2 is equipped with a reagent feed pipe with a reagent feed valve 10. The conical bottom discharge pipe of the reagent pressurizing tank, after connecting to the reagent pressurizing tank discharge valve 11, leads to the mixing tank 1 and discharges within the mixing tank. The top of the tank is divided into four paths: front, back, left, and right. Each path is connected to a reagent spray pipe 3 and extends into the oil mixing tank 1. Each reagent spray pipe 3 is equipped with multiple reagent nozzles 5 facing different directions. The oil mixing tank 1 has a cylindrical body and a conical bottom. A stirring motor 7 connected to a stirring paddle 6 is installed in the middle of the top of the tank. The upper right side of the oil mixing tank 1 is equipped with a feed pipe with a No. 4 biodiesel feed valve 9. The conical bottom discharge pipe of the oil mixing tank 1 is connected to the oil mixing tank discharge valve 12, the feeding pump 8, and the post-pump valve 13 in sequence, and then connected to the No. 4 biodiesel transition tank.

[0005] The above-mentioned oil mixing device can increase or decrease the number and length of the stirring paddles as needed, and can also increase or decrease the number of reagent nozzles 3 and reagent nozzles 5 as needed.

[0006] During operation, open the reagent feed valve 10 to pump the reagent into the reagent pressurization tank 2 for pressurization, turn on the stirring motor 7 to stir, open the reagent pressurization tank discharge valve 11 to spray the reagent through the reagent spray pipe 3 and reagent nozzle 5, after spraying the reagent and stirring for a certain period of time, turn off the stirring motor 7, and pump the well mixed oil sample to the No. 4 biodiesel transition tank through the feeding pump 8.

[0007] This utility model's No. 4 biodiesel rapid mixing device has the following technical features and beneficial effects:

[0008] 1. Using this device to mix reagents in No. 4 biodiesel can effectively reduce the kinematic viscosity and sulfur content of No. 4 biodiesel.

[0009] 2. Uniform, small-volume reagents mixed quickly with No. 4 biodiesel will not cause excessively high local reagent concentrations in the oil mixing tank 1, and will not easily cause other reactions.

[0010] 3. The entire mixing device has a simple structure, is easy to operate, and has a fast mixing speed. Attached Figure Description
