Description

Technical Field

[0001] The utility model relates to the technical field of benzyl glycidyl ether preparation, in particular to a preparation device for benzyl glycidyl ether. Background Art

[0002] Benzyl glycidyl ether is a colorless, transparent liquid with little odor, low toxicity, low volatility and good chemical stability. It is often used as an epoxy reactive diluent to reduce the viscosity of epoxy resins. It has a good dilution effect and is widely used in electronics, electrical appliances, electromechanical, machinery, construction, coatings and adhesives. The production of benzyl glycidyl ether requires the use of a preparation device.

[0003] A general preparation device, such as the preparation method of benzyl glycidyl ether with application number "CN202210584414.8", cannot effectively mix and stir the materials during use, so that the materials cannot be fully mixed, which is not conducive to the preparation of benzyl glycidyl ether. Utility Model Content

[0004] The utility model aims to provide a preparation device for benzyl glycidyl ether to solve the problems raised in the above background technology.

[0005] A preparation device for benzyl glycidyl ether comprises a reaction kettle and a partition: the interior of the reaction kettle is divided into an inner and an outer part by the partition, the outer part is a heating zone, and the inner part is a stirring and mixing zone, a pressure valve is arranged on the side of the heating zone, a stirring mechanism is arranged inside the mixing zone, and a feeding mechanism is arranged at the upper end of the reaction kettle.

[0006] Preferably, heating rods are arranged at equal angles inside the heating zone, and the heating rods are vertical.

[0007] The device is heated by a heating rod, and when the air pressure in the heating zone is high, the gas will be discharged through a pressure valve, thereby avoiding excessive air pressure in the heating zone.

[0008] Preferably, a motor is provided at the lower end of the reactor, a central gear is provided at the output end of the motor, and connecting gears are symmetrically provided on the sides of the central gear.

[0009] The motor drives the central gear to rotate. When the central gear rotates, it drives the connecting gears on both sides to rotate. When the connecting gears rotate, they drive the stirring mechanism to rotate, thereby stirring and mixing the materials.

[0010] Preferably, the stirring mechanism includes a fixed shaft, a first stirring rod and a second stirring rod. A fixed shaft is provided at the upper end of the connecting gear. The fixed shaft is symmetrically rotated in the stirring and mixing zone. A first stirring rod is provided on the side of the fixed shaft. A second stirring rod is rotatably provided inside the first stirring rod.

[0011] The fixed shaft will rotate with the connecting gear. When the fixed shaft rotates, it will drive the first stirring rod and the second stirring rod to rotate. When the first stirring rod and the second stirring rod rotate, the materials will be stirred and mixed. At the same time, the rotation directions of the two fixed shafts are the same, so when the two second stirring rods approach, since the moving directions of the two second stirring rods are opposite, the two will collide, thereby squeezing and mixing the materials, thereby making the mixing process more uniform.

[0012] Preferably, a slideway is provided at the upper end of the interior of the reactor, a connecting ball is slidably provided inside the slideway, a fixing ring is provided at the lower end of the connecting ball, and a scraper is provided at the lower end of the fixing ring.

[0014] Preferably, the feeding mechanism comprises a feeding hopper and a sealing plate, the feeding hopper is arranged at the upper end of the reaction kettle, and the upper end of the feeding hopper is provided with a sealing plate.

[0015] The material is added via a feed hopper which can be closed by a blocking plate.

[0018] The beneficial effects of the utility model are:

[0019] 1. When the device is in use, the material is stirred and mixed by the first stirring rod, and because the directions of the intersections of the fluids on both sides are opposite, the stirring and mixing effect will be enhanced. During the stirring and mixing process, the material will be continuously squeezed and crushed, thereby effectively increasing the stirring and mixing effect. At the same time, the inner wall of the device is cleaned by the rotation of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS
