Description

Technical Field

[0001] This utility model belongs to the field of plasticizer esterification reaction technology, and in particular relates to a plasticizer esterification reaction apparatus. Background Technology

[0002] As is well known, plasticizers are substances added during the molding of polymers such as rubber, plastics, and coatings to increase their plasticity, flowability, and make the finished product flexible. They are essential additives in the plastics industry. However, studies have shown that phthalic plasticizers have potential carcinogenicity, and the production volume of green plasticizers such as epoxy resins and citrate esters is difficult to meet the huge market demand in the short term. Therefore, phthalic plasticizers will remain the main products on the market in the future.

[0003] Existing plasticizers react inside a reactor, but harmful gases are generated during the reaction. These gases are released directly into the atmosphere without treatment, which will have a certain impact on the environment. At the same time, long-term inhalation of harmful gases by workers will cause certain damage to their health. Therefore, a plasticizer esterification reaction device is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a plasticizer esterification reaction apparatus to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a plasticizer esterification reaction device, comprising a tank and a filter box. The tank has a mounting cover on its upper surface, an inlet on its upper surface, a servo motor on its upper surface, and a connecting air pipe. The filter box contains a filter plate and an activated carbon filter plate arranged from top to bottom. An air pump is connected to one side of the filter box, and an air suction pipe is connected to its upper surface. A rotating rod is located at the output end of the servo motor. A heating chamber is formed inside the tank, containing a heating tube. An inlet pipe and a outlet pipe are respectively formed on the circumferential side of the tank, and a heating base is provided on the circumferential side of the tank.

[0007] Furthermore, the tank body is fitted with a heat insulation plate on its periphery, and the bottom surface of the tank body is symmetrically provided with liquid outlet pipes. The liquid outlet pipes and the feed inlet are both connected to a solenoid valve on their periphery. The liquid inlet pipe and the liquid outlet pipe are respectively connected to the heating chamber. The heating base is electrically connected to the heating tube. The heating chamber is provided with heat-conducting oil, and the heating tube has a spiral plate structure.

[0008] Furthermore, the rotating rod is provided with several stirring blades on its circumferential side, and the stirring blades are disposed inside the tank. The free end of the connecting air pipe is fixedly connected to the top of the suction pipe through a connecting flange. The upper surface of the filter box is connected to the suction pipe. Several support legs are provided at equal intervals on the bottom surface of the tank.

[0009] This utility model has the following beneficial effects:

[0010] This invention utilizes a servo motor to drive a rotating rod at the output end. The rotating rod, in turn, drives several equally spaced stirring blades on the circumferential side to stir the liquid inside the tank. Simultaneously, a heating element is activated to heat the heat transfer oil within the heating chamber. This simultaneous heating and stirring of the liquid inside the tank further enhances the reaction efficiency. Furthermore, a heat insulation plate, a polyurethane-aerogel composite board, is used to insulate the tank's circumference. This board combines the low cost of polyurethane with the high performance of aerogel, exhibiting a thermal conductivity of approximately 0.018–0.022 W / (m·K). During the reaction of the liquid inside the tank, some harmful gases may be generated. In this case, an air pump is activated. The air pump extracts the generated gases through an air intake pipe and connecting pipe. The gases are then filtered through a filter plate and an activated carbon filter plate (a high-efficiency filter plate made of glass fiber or synthetic fiber) before being discharged by the air pump, minimizing harm to workers.
