Description

Technical Field

[0001] The utility model belongs to the technical field related to organic chemistry, and particularly relates to a continuous production device for ester compounds. Background Art

[0002] Continuous production equipment for ester compounds refers to chemical equipment used to realize continuous production of esterification reactions. This equipment usually includes a series of interconnected units, such as oxidation units, esterification units and distillation units, which work together to complete the pretreatment of raw materials, chemical reactions and separation and purification of products. Compared with traditional batch processing methods, continuous production technology can improve production efficiency, reduce energy consumption and reduce manual operations, while ensuring the stability of product quality. However, it still has the following disadvantages in actual use:

[0003] During the production process of the continuous production equipment of ester compounds, the produced products are directly outputted, and then the produced ester compounds are outputted through liquid separation. During the working process, the production of ester compounds requires a longer time for liquid separation, and the working efficiency is not high enough;

[0004] When the continuous production equipment of ester compounds is in operation, the raw materials of the compounds need to be heated. During the heating process, the liquid is directly heated by the heating structure. During the heating process, the heating efficiency is not high enough. Utility Model Content

By arranging a reaction kettle shell, a driving motor, an output hose and an internal heating jacket, the utility model solves the problems that the continuous production device for ester compounds needs to take out the reactants for liquid separation before the product esters can be taken out, which is inconvenient to operate and the material heating efficiency is not high enough.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a continuous production device for ester compounds, comprising a reactor shell, a driving motor, an output hose and an inner heating sleeve, wherein the inner wall of the reactor shell is fixed with the inner heating sleeve, a driving motor is arranged below the reactor shell, a rotating shaft is fixed to the output end of the driving motor, the rotating shaft is movably connected to the bottom end of the reactor shell, an output hose is fixed to the bottom end of the reactor shell on one side of the rotating shaft, a floating block is fixed to the outer peripheral surface of the top end of the output hose, when working, the inner heating sleeve is fixed therein through the reactor shell, and the reacted materials are contained therein through the reactor shell, the driving motor drives the rotating shaft to rotate the stirring blade, the materials in the reactor body are stirred evenly through the rotation of the stirring blade, the ester generated in the reactor shell is discharged through the output hose, and the materials in the reactor shell are heated through the inner heating sleeve.

[0008] Furthermore, a through hole is provided at the bottom end of the reactor shell on one side of the rotating shaft, the output hose is passed through and fixed in the through hole, and the reactor shell fixes the output hose through the through hole.

[0009] Furthermore, a three-way pipe is fixedly passed through the top of the reactor shell, and an inlet and outlet pipe is fixedly connected to the bottom of the reactor shell on the side of the rotating shaft away from the through hole. The reactor shell transports carboxylic acid and alcohol raw materials to the reactor body through the three-way pipe.

[0010] Furthermore, stirring blades are fixed in a ring array on the outer peripheral surface of the top end of the rotating shaft, and the stirring blades are arranged in the shell of the reactor. When the rotating shaft rotates, it drives the stirring blades to rotate, so as to slowly stir the materials in the shell of the reactor.

[0011] Furthermore, a fixed plate is fixed on the circumference of the drive motor, and support legs are fixed in a circular array inside the fixed plate outside the drive motor. The drive motor is supported on the ground by the fixed plate and the support legs, and the reactor shell is supported on the ground by the support legs.

[0012] Furthermore, the top end of the output hose is fixedly connected with a hollow ball, and the surface of the hollow ball is provided with connecting holes in a ring array, and the ester is transported to the output hose through the connecting holes on the hollow ball.

[0013] Furthermore, a fixing plate is fixed in a circular array on the inner wall of the inner heating sleeve, and openings are equidistantly penetrated through one side of the fixing plate along the center line in the vertical direction. The inner heating sleeve increases the efficiency of material heating through the openings on the fixing plate.

[0014] The utility model has the following beneficial effects:

[0015] The utility model solves the problem that the ester compound continuous production equipment needs to take out the reactants for liquid separation before the product esters can be taken out, which is inconvenient to operate, by arranging a reactor shell, a driving motor and an output hose. The driving motor drives the rotating shaft to rotate, driving the stirring plate to rotate slowly, and at the same time, the catalyst is transported to the reactor shell through the inlet and outlet pipes to catalyze the materials in the reactor. After the reaction is completed, the driving motor is turned off, so that the generated ester substances float stably in the reactor shell. In the reactor shell, the output hose transports the ester substances into the hollow ball through the connecting holes on the hollow ball, transports them to the output hose through the hollow ball, and outputs them to the ester collection equipment through the output hose. The ester compound continuous production equipment can directly take out the ester substances generated therein, and the operation is more convenient.

[0016] The utility model solves the problem of insufficient heating efficiency of materials in ester compound continuous production equipment by arranging a reactor shell, a driving motor and an internal heating jacket. During the operation of the driving motor, the driving shaft rotates, driving the stirring plate to rotate slowly. Through the slow rotation of the stirring plate, the materials and catalysts in the reactor shell pass through the fixing plate on the inner wall of the internal heating jacket and pass through the openings, thereby destroying the laminar flow of the liquid flow, so that the materials in the reactor shell are fully and evenly heated during operation, and the heating efficiency is higher.
