[0013] Further, the reaction kettle body is provided with an asymmetric micro-splashing self-adaptive oxygen removal device, which comprises a liquid ammonia tank, a micro-flow pump, a liquid ammonia pump-in pipe, an inclined buffer cavity, a one-way valve shell, a micro-bead one-way valve and a micro-bead forming layer. The liquid ammonia tank and the micro-flow pump are arranged on one side of the reaction kettle body. The input end of the micro-flow pump is communicated with the liquid ammonia tank. The liquid ammonia pump-in pipe is communicated with the output end of the micro-flow pump. The one-way valve shell is arranged on the inner side wall of the reaction kettle body. The one-way valve shell is in a hemispherical shape. The micro-bead one-way valve is communicated with the side wall of the one-way valve shell. A plurality of micro-bead one-way valves with different sizes are arranged on the one-way valve shell. The micro-bead forming layer is wrapped outside the one-way valve shell. The micro-bead forming layer is in a hemispherical shape with the same center as the one-way valve shell. A one-way valve micro-bead generating cavity is arranged between the micro-bead forming layer and the one-way valve shell. The one-way valve micro-bead generating cavity facilitates the formation of micro-beads from the micro-bead one-way valve. A plurality of micro-bead holes with different sizes are arranged on the micro-bead forming layer. The inclined buffer cavity is communicated with one end of the liquid ammonia pump-in pipe away from the micro-flow pump. The other end of the inclined buffer cavity is communicated with the upper end of the one-way valve shell in an inclined manner. The asymmetrically arranged micro-bead holes and the micro-bead one-way valves correspond to each other, which facilitates the formation of micro-beads. The one-way valve shell is wrapped with a liquid ammonia cooling channel. The liquid ammonia cooling channel is communicated with the one-way valve shell through a through hole. The liquid ammonia cooling channel facilitates the low temperature of the one-way valve shell and the stable formation of micro-beads. The inclined buffer cavity facilitates the pumping of liquid ammonia from the upper end of the one-way valve shell. The micro-flow pump pumps the liquid ammonia in the liquid ammonia tank to the one-way valve shell through the micro-bead one-way valve. The liquid ammonia flowing out of the micro-bead one-way valve forms splashing micro-beads after passing through the asymmetrically arranged micro-bead one-way valves with different sizes. The splashing micro-beads flow out of the upper end of the micro-bead forming layer first. With the increase of the number of micro-beads, the micro-beads diffuse from the lower end of the micro-bead forming layer to the reaction kettle body under the action of gravity, forming unstable splashing and shaking, which makes the mixing more uniform. The melting point of ethyl oleate is -32℃, and the melting point of liquid ammonia is -33.5℃. Part of the liquid ammonia flowing into the reaction kettle body vaporizes, and the temperature decreases after absorbing heat, forming liquid ammonia micro-beads in a gas-liquid mixed state. The low temperature of liquid nitrogen can make ethyl oleate solidify instantly. Ethyl oleate is wrapped outside the liquid ammonia micro-beads, making the reaction more comprehensive and uniform. Through the principle of homogeneity and the mixing of liquid ammonia itself, the ethyl oleate and liquid ammonia are mixed uniformly in 360°, replacing the oxidant in the reaction kettle. This effectively solves the contradiction that ammonia gas needs to be gathered together to facilitate ammonia replacement of oxidants and needs to be separated to ensure that the contact area between ammonia gas and the liquid is uniform and maximized. It overcomes the technical difficulties of gathering and dispersing the liquid and mixing and dispersing the elastic ball. By cutting off the mixing mechanism and the separation mechanism from the device, the liquid and ammonia gas are better mixed and separated in the absence of a separation mechanism and a cutting mechanism. The micro-splashing self-adaptive oxygen removal device better controls the technical effect of the peroxide value of the product, making the purity of the liquid very high.

[0014] Further, the side walls of the first and second ingredient tanks are respectively provided with scales, which facilitate accurate reading of the liquid levels of the first and second ingredient tanks and accurate control of the material proportion; the dynamic adjustment type memory reaction kettle is provided with a support frame, and the first and second ingredient tanks are arranged on the support frame, which supports and fixes the first and second ingredient tanks.

The ingredient vacuum valve 22 is closed and the finished product vacuum valve 56 is opened, and the inside of the preset negative pressure vacuum finished product storage tank 7 is drawn into a vacuum negative pressure state by the vacuum pump 2 through the finished product vacuum pipe 55, and the oxide in the preset negative pressure vacuum finished product storage tank 7 is drawn out. After the vacuum is drawn, the ingredient vacuum valve 22 is closed and the finished product vacuum valve 56 is closed, the heat inlet pipe 36 and the heat outlet pipe 38 are connected to the heating device, the heating device generates hot gas which is sent into the reaction kettle body 30 through the heat inlet pipe 36 to heat the material in the reaction kettle body 30. The hot gas in the reaction kettle body 30 is discharged into the heat preservation reflux pipe 52 through the transition pipe 41 to continuously heat the reaction kettle body 30 and then discharged through the heat outlet pipe 38, ensuring that the pressure in the reaction kettle body 30 is normal. The elastic rubber sleeve 15 is elastically sleeved on the bottle opening of the material tank, and the sealing air bag 16 is placed at the tank opening or bottle opening. The pressing air bag 20 is pressed to press the gas in the pressing air bag 20 into the sealing air bag 16, and the sealing air bag 16 is inflated to seal the bottle opening of the material tank.

The feeding valve 19 is opened, the feeding hose 13 is inserted into the material tank, and the crude ethyl oleate in the material tank is pressed into the ingredient tank 10 under the action of the pressure difference. When the sealing air bag 16 needs to be removed from the tank opening or bottle opening of the material tank, the exhaust valve 29 is opened to discharge the gas in the sealing air bag 16 through the exhaust pipe 28, and then the sealing air bag 16 and the elastic rubber sleeve 15 can be removed. This ensures the sealing of the material tank when the material is extracted, reduces the possibility of oxide entering the material tank to oxidize the ethyl oleate, opens the feeding valve 61, and sends the modified activated carbon into the ingredient tank 11 through the feeding pipe 60.

The liquid discharge valve 53 and the circulating valve 54 are closed, the crude ethyl oleate in the ingredient tank 10 is poured into the reaction kettle body 30 through the discharge valve 24, and when the temperature in the reaction kettle body 30 drops to 70-80℃, the modified activated carbon in the ingredient tank 11 is poured into the reaction kettle body 30 through the discharge valve 26. After the material is poured, the discharge valve 24 and the discharge valve 26 are closed. The stirring motor 31 drives the stirring shaft 32 and the stirring blade 39 to rotate and drive the insulated dynamic adjustment type elastic memory ball 33 to stir and absorb decolorization for 30 minutes. The shape memory alloy spring 47 becomes longer after being heated, which facilitates dynamic movement in the reaction kettle body 30 with the rotation of the stirring shaft 32 and the stirring blade 39. When the shape memory alloy spring 47 collides with the reaction kettle body 30 or the stirring shaft 32 and the stirring blade 39, the spring force is intensified to mix the materials, so that the materials are mixed more quickly and uniformly.The shaking degree of the insulating dynamic adjustment type elastic memory ball 33 is dynamically adjusted according to the volume of the material and the stirring speed of the stirring shaft 32. When the material is discharged, the reaction kettle body 30 is no longer heated to restore normal temperature, the shape memory alloy spring 47 restores the deformation shrinkage, so that the volume of the insulating dynamic adjustment type elastic memory ball 33 becomes smaller, the insulating dynamic adjustment type elastic memory ball 33 is conveniently discharged from the ball discharge pipe 35 for cleaning, the liquid discharge valve 53 is closed and the circulating valve 54 is opened, the first centrifugal pump 49 is used to control the hot control to discharge the liquid medicine in the reaction kettle body 30 through the discharge tee pipe 4 and then send it into the plate and frame filter 51 through the circulating liquid pipe 50, and then return it to the reaction kettle body 30 through the backflow pipe 52, the first centrifugal pump 49 repeatedly circulates and filters the liquid medicine in the reaction kettle body 30 through the plate and frame filter 51, when the liquid medicine is clarified, the circulating valve 54 is closed, the temperature is increased to 140-150℃, the micro-flow pump 62 is opened to micro-flow into liquid ammonia into the reaction kettle body 30, and oxide replacement is carried out, the inclined buffer cavity 68 pumps the liquid ammonia out from the upper end of the one-way valve shell 69, the micro-flow pump 62 pumps the liquid ammonia in the liquid ammonia tank 65 out to the one-way valve shell 69, and then flows out through the micro-bead one-way valve 70, the liquid ammonia flowing out from the micro-bead one-way valve 70 forms a splashing type micro-bead after passing through the asymmetrically positioned micro-bead one-way valves 70 with different sizes, the splashing type micro-bead first flows out from the upper end of the micro-bead forming layer 72, and as the number of micro-beads increases, the micro-beads diffuse from the lower end of the micro-bead forming layer 72 to the reaction kettle body 30 under the action of gravity to form unstable splashing and shaking, so that the mixing is more complete and uniform, a part of the liquid ammonia flowing into the reaction kettle body 30 is gasified, the temperature is lowered after heat absorption, and a gas-liquid mixed state of liquid ammonia micro-bead is formed, the low temperature of the liquid nitrogen can make the ethyl oleate solidify instantaneously, the ethyl oleate is wrapped outside the liquid ammonia micro-bead, the reaction is more complete and uniform, and through the homogeneous principle and the mixing of the liquid ammonia itself, the ethyl oleate and the liquid ammonia are mixed and replaced in 360° full range to replace the oxides in the reaction kettle body 30, effectively solving the contradiction that the ammonia gas needs to be gathered together to facilitate ammonia replacement of oxides and needs to be separated to ensure that the contact area between the ammonia gas and the liquid medicine is uniform and maximized, overcoming the technical difficulties that the liquid medicine needs to be gathered and dispersed and the insulating dynamic adjustment type elastic memory ball 33 needs to be mixed and dispersed, cutting off the mixing mechanism and the separation mechanism from the device, and in the case of no separation mechanism and cutting mechanism, the liquid medicine and the ammonia gas are better mixed and separated, and the technical effect of self-mixing and separation is achieved, the micro-splashing type self-adaptive deoxidization better realizes the technical effect of controlling the peroxide value of the product, the purity of the liquid medicine is very high, after the oxide replacement is completed, the discharge valve two 26 and the ammonia pump 62 are closed, the temperature of the liquid medicine in the reaction kettle body 30 is cooled to below 45℃, the liquid discharge valve 53 is opened, the liquid medicine is filtered through the bag filter 6 to obtain the primary filtered filtrate, the primary filtered filtrate is pumped into the pre-set negative pressure vacuum finished product storage tank 7 by the second centrifugal pump 8 for mixing for 30 min, and the liquid medicine primary product is obtained after inspection, when filling is needed, the discharge valve 58 is opened,The initial product of the liquid medicine in the preset negative pressure vacuum finished product storage tank 7 flows to the barrel filter 9 through the discharge pipe 57, is filtered, and is discharged through the filling pipe 59 to be filled.
