Technical Field
[0001] The utility model relates to the technical field of insulating oil production, in particular to a uniform ester oil device. Background Art
[0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, and food industries. They are mainly pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, polymerization, and condensation. The principle is to stir the various liquids in the reactor through an agitator to make the materials evenly dispersed, thereby fully.
[0003] In the production process of transformer ester insulating oil, a reactor is required for mixing. For example, the utility model with announcement number CN203816616U discloses a filtering insulating oil reactor, which includes a reactor body, a driving motor, a rotating rod, a stirring disk, an inlet and a discharge port. The upper end of the reactor body is provided with an inlet, and the lower end is provided with a discharge port. The top end of the rotating rod is connected to the driving motor, and the tail end is provided with a stirring disk. The rotating rod and the stirring disk are both placed in the reactor body. A filter disk is sleeved on the rotating rod, and a hydraulic rod is provided on the upper end of the filter disk. The top end of the hydraulic rod is connected to the control motor. The reactor can complete the impurity filtration of the insulating oil during the stirring operation, saving costs and improving efficiency.
[0004] However, when the above application is actually used, for the existing insulating oil being mixed and processed in a reactor, when the insulating oil stirred in the reactor is filtered for impurities simultaneously by a filtering mechanism, the impurities are easily precipitated at the bottom of the reactor, resulting in insufficient filtration. At the same time, the filtered impurities are not easy to be discharged from the filter screen in the inner cavity of the reactor, thereby affecting the further reaction of the reactor to the insulating oil. Therefore, a uniform ester oil device is proposed to solve the above problem. Utility Model Content

[0025] In this embodiment, when the insulating oil raw material is poured into the mixing barrel 1 and stirred and filtered by the stirring rod 47 on the sleeve rod 44, the reacted impurities can be blocked and filtered by the filter screen 48, and the started electric telescopic rod 45 pushes the connecting cover 2 to move upward to drive the connecting ring 46 and the filter screen 48 to rise, so that the mixed insulating oil can be discharged through the discharge pipe 6, and the reacted impurities can be well filtered and separated.
[0026] Among them, the outer side of the feeding port 3 is threadedly connected with a sealing cover, the lower end of the mixing cylinder 1 is connected with a discharge pipe 6, and a valve is fixedly installed on the outer side of the discharge pipe 6.
