[0001] The present invention relates to the technical field of the preparation of zinc fatty acid soaps, and particularly to a preparation method and device for a mixture of zinc fatty acid soaps. Background Art

[0002] Zinc fatty acid soap is an important organic compound, which is formed by the reaction of fatty acid and zinc salt. This compound is widely used in the fields of detergents, lubricants, emulsifiers, etc. due to its good surface activity and emulsifying properties.

[0003] Currently, in the preparation and processing of a mixture of zinc fatty acid soaps, such as the patent with the prior art publication number CN104693813A, this invention discloses a zinc fatty acid soap-based rubber internal mold release agent. The raw materials according to mass include: 450 - 650 kg of stearic acid, 25 - 40 kg of zinc compound, 350 - 450 kg of stearic acid amide, 90 - 100 kg of paraffin wax, and 5 - 15 kg of diethylene glycol ether; the preparation method of the zinc fatty acid soap-based rubber internal mold release agent includes the following steps: (1) Put in stearic acid, place a quantitative amount of stearic acid in a reaction kettle, heat and stir; (2) Put in the zinc compound; (3) Add stearic acid amide, paraffin wax, and diethylene glycol ether in sequence; (4) Granulate the product.

[0004] However, the reaction kettle in this preparation device has relatively single functionality, which is not convenient for processing such as washing and evaporation of the saponified zinc fatty acid soap, and is not convenient for improving the stirring efficiency and stirring uniformity of the mixture, thus reducing the convenience of use. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a preparation method and device for a mixture of zinc fatty acid soaps, which can improve the mixing and processing efficiency of raw materials, improve the uniformity of the mixture of zinc fatty acid soaps, facilitate the preparation and processing of zinc fatty acid soaps by different processes in a heat-conducting inner liner, and improve the production efficiency.

[0006] A preparation method and device for a mixture of zinc fatty acid soaps of the present invention include a housing and a heat-conducting inner tank. The heat-conducting inner tank is installed on the inner side wall of the housing, and a chamber is provided between the heat-conducting inner tank and the housing; it also includes a stirring device, a discharging device, a conveying device, a feed pipe, a rotating shaft and a spiral blade. The feed pipe is installed on the outer side wall of the housing, and the output end of the feed pipe is communicated with the heat-conducting inner tank. The rotating shaft is rotatably installed on the stirring device, and the spiral blade is installed on the outer side wall of the rotating shaft. The stirring device is used to stir the mixture in the heat-conducting inner tank in opposite directions, and the stirring device is used to drive the rotating shaft to rotate. The discharging device is communicated and arranged at the bottom end of the housing, and the discharging device is used to control the discharge of the materials in the housing. The conveying device is communicated with the heat-conducting inner tank, and the conveying device is used to circulate and convey the mixture in the heat-conducting inner tank, and the conveying device is used to add different mixtures into the heat-conducting inner tank; the raw materials of zinc fatty acid soaps such as stearic acid, palmitic acid and oleic acid ester are added into the interior of the heat-conducting inner tank through the feed pipe according to a certain proportion, and then the mixture is stirred and mixed by the stirring device therein. The raw materials are mixed and stirred in opposite directions by the mixing device, so as to improve the mixing and processing efficiency of the raw materials. At the same time, the stirring device drives the rotating shaft to rotate, and after the rotating shaft rotates, it drives the spiral blade to rotate, so that the spiral blade lifts and conveys the raw materials at the bottom of the heat-conducting inner tank upward, thus avoiding the deposition of raw materials at the bottom and improving the uniformity of the mixing of zinc fatty acid soaps. By circulating and conveying the heating medium in the chamber, the heating medium heats the heat-conducting inner tank, and the heat-conducting inner tank heats and melts the internal raw materials of zinc fatty acid soaps through heat conduction. Under the stirring state, a zinc source and a catalyst are added into the heat-conducting inner tank through the conveying device to be mixed with the raw materials of zinc fatty acid soaps. During this process, saponification reaction occurs between the fatty acid and the zinc source under the action of the catalyst to generate zinc fatty acid soap. After the saponification reaction is completed, the reaction product is cooled and cooled down. Then, deionized water is added into the heat-conducting inner tank for washing, and then the water phase is separated. Then, the washed mixture of zinc fatty acid soaps is heated for vacuum distillation to remove water and low-boiling impurities, and a refined mixture of zinc fatty acid soaps is obtained.

The piston is slidably installed inside the cylinder body. The output end of the first conveying pipe is communicated with the cylinder body, and the input end of the first conveying pipe is communicated with the inside of the heat-conducting inner liner.

The third conveying pipe is communicatively arranged on the first conveying pipe, and two groups of third one-way valves are respectively communicatively arranged on the input end of the third conveying pipe. The input ends of the two groups of turntables are respectively communicated with the two storage tanks. By driving the turntable to rotate through the stirring device, the turntable drives the piston to move up and down through the connecting rod. When the piston moves upward, the material at the lower part inside the heat-conducting inner liner is extracted through the first conveying pipe and the first one-way valve. After the piston moves downward, the material extracted inside the cylinder body by the piston is conveyed to the upper part inside the heat-conducting inner liner through the second conveying pipe, thereby improving the up-and-down circulation flow effect of the material inside the heat-conducting inner liner, and improving the mixing uniformity and mixing efficiency of the material.

Multiple inlets are arranged at the lower part of the outer side wall of the lifting cylinder, and multiple outlets are arranged at the upper part of the outer side wall of the lifting cylinder.

At the same time, by driving the rotating shaft to rotate through the driving device, the spiral blades lift and convey the mixture entering the lifting cylinder upward, and the lifted and conveyed mixture is discharged outward through the outlet at the upper part of the lifting cylinder, thereby improving the up-and-down circulation mixing effect of the mixture inside the heat-conducting inner liner and improving the processing uniformity of the mixture.

When the motor runs, it drives the first bevel gear to rotate. After the first bevel gear rotates, it drives the kit and the lifting cylinder to rotate in opposite directions through meshing with the second bevel gear and the third bevel gear respectively, thereby improving the effect of stirring the mixture in opposite directions and at the same time improving the effect of the spiral blade rotating to lift and convey the mixture.

[0010] Preferably, the discharging device includes a discharge pipe, a first stop valve and a second stop valve. The discharge pipe is communicated and arranged at the bottom end of the housing, the first stop valve is communicated and arranged on the discharge pipe, and the input end of the second stop valve is communicated with the discharge pipe; When deionized water is added to the mixture in the heat-conducting inner tank for washing, the zinc fatty acid soap and the aqueous phase are stratified by natural standing. The stratified aqueous phase is located below the zinc fatty acid soap. At this time, by opening the second stop valve, the aqueous phase is discharged and separated, and by opening the first stop valve, it is convenient to discharge the separated zinc fatty acid soap.

Let the washed reaction product stand for 10-20 minutes to naturally separate layers. Since the density of the aqueous phase is large and the density of the organic phase of the zinc fatty acid soap is small, the aqueous phase will settle to the lower layer and the organic phase will float on the upper layer; S6. Drain the lower aqueous phase to separate it from the zinc fatty acid soap; S7. Heat the washed zinc fatty acid soap mixture to 100-110 °C for vacuum distillation to remove water and low-boiling impurities, and obtain a refined zinc fatty acid soap mixture.

By circulating and conveying the heating medium in the chamber, the heating medium heats the heat-conducting inner tank, and the heat-conducting inner tank heats and melts the fatty acid zinc soap raw materials inside through heat conduction. Under the stirring state, a zinc source and a catalyst are added into the heat-conducting inner tank through a conveying device to mix them with the fatty acid zinc soap raw materials. During this process, a saponification reaction occurs between the fatty acid and the zinc source under the action of the catalyst to generate fatty acid zinc soap. After the saponification reaction ends, the reaction product is cooled and the temperature is reduced. Then, deionized water is added into the heat-conducting inner tank for washing, and then the water phase is separated. Then, the washed fatty acid zinc soap mixture is heated for vacuum distillation to remove water and low-boiling impurities, and a refined fatty acid zinc soap mixture is obtained.

At the same time, the stirring device drives the rotating shaft 104 to rotate. After the rotating shaft 104 rotates, it drives the spiral blade 105 to rotate, so that the spiral blade 105 lifts and conveys the raw materials at the bottom of the heat-conducting inner container 102 upward. By circulating and conveying the heating medium in the chamber, the heating medium heats the heat-conducting inner container 102, and the heat-conducting inner container 102 heats and melts the raw materials of zinc fatty acid soap inside through heat conduction. Under the stirring state, the zinc source and the catalyst are added into the heat-conducting inner container 102 through the conveying device to mix them with the raw materials of zinc fatty acid soap. During this process, the fatty acid and the zinc source undergo a saponification reaction under the action of the catalyst to generate zinc fatty acid soap. After the saponification reaction ends, the reaction product is cooled and the temperature is reduced. Then, deionized water is added into the heat-conducting inner container 102 for washing. After that, the aqueous phase is separated. Then, the washed zinc fatty acid soap mixture is heated for vacuum distillation to remove water and low-boiling impurities, and a refined zinc fatty acid soap mixture is obtained.

[0022] The main functions achieved by the present invention are as follows: improving the mixing and processing efficiency of raw materials, enhancing the uniformity of the mixture of zinc fatty acid soap, facilitating the preparation and processing of zinc fatty acid soap in the heat-conducting inner container 102 by different processes, and improving the production efficiency.
