Description

A synthesis reactor for quantitative synthesis reaction

Technical Field

The utility model relates to the technical field of synthesis kettle equipment, and specifically relates to a synthesis kettle used for quantitative synthesis reaction.

Background Art

A synthesis reactor is a device used for chemical reactions. It is usually made of high-temperature and corrosion-resistant materials, such as stainless steel or glass. The synthesis reactor is equipped with a feeding and discharging system for adding reactants and collecting products, and a stirring device for stirring and synthesizing the reactants in the synthesis reactor. The synthesis reactor is widely used in chemical research and industrial production, and can improve the efficiency and reliability of synthesis reactions.

In the prior art, for example, patent No. CN217594565U, a quantitative feeding synthesis reactor comprises a reactor body, a feeding pipe is arranged on the side surface of the reactor, the upper end of the feeding pipe is connected with a measuring cylinder, the upper end of the measuring cylinder is provided with a receiving cylinder and the inner surface of the receiving cylinder is provided with a quantitative device, the quantitative device comprises a fixed frame, a sliding hole is opened on the surface of the fixed frame and a toothed plate is slidably connected in the sliding hole, a fixed disk is connected to the bottom of the valley at the lower end of the toothed plate, the fixed disk is against the inner wall of the receiving cylinder, a rotating rod is rotatably connected in the receiving cylinder and a gear is fixed at one end of the rotating rod close to the toothed plate, the gear and the toothed plate provided on the rotating shaft are meshed with each other, the device can drive the toothed plate to slide through the gear by rotating the rotating rod, and the sliding of the toothed plate can drive the fixed disk fitted on the inner wall of the receiving cylinder to separate from the receiving cylinder to generate a gap for feeding, and the size of the gap can be controlled by the rotating shaft, and the quantitative device is provided to avoid the traditional need to manually pour the solution into the measuring cylinder, and avoid the manual pouring caused by slight shaking of the arm, which makes it impossible to accurately pour into the measuring cylinder, thereby improving the work efficiency of the staff.

However, the above-mentioned quantitative feeding synthesis reactor still has many shortcomings. For example, when conveying reactants, the device controls the switch of conveying reactants by gradually separating the fixed disk from the inner wall of the accommodating tube or sticking to the inner wall of the accommodating tube through the rotating rod. However, the process of gradually opening or closing the fixed disk by rotating to control the fixed disk is relatively slow, resulting in excessive conveyance of reactants, so that the excess reactants need to be processed frequently, which affects the work efficiency. In addition, the device needs to convey the reactants into the measuring cylinder first, and then measure and quantitatively discharge the excess reactants before entering the reactor. The process is relatively cumbersome, and the amount of reactants conveyed at one time cannot exceed the measuring cylinder. When conveying the reactants continuously, the process of conveying them in multiple times is also relatively cumbersome.
