Description

Technical Field

[0001] This utility model belongs to the field of glass-lined reactor application technology, and specifically relates to a miniaturized experimental high-pressure glass-lined reactor. Background Technology

[0002] Glass-lined reactors are important industrial equipment used in the chemical industry. They are made by repeatedly firing high-temperature glass enamel with a high silicon content at around 900℃ to allow the enamel layer to adhere to the surface of a metal substrate. They are widely used in the chemical, pharmaceutical, dye, and food industries. Glass-lined reactors require glazing, including base glaze and top glaze, and the glazing process is quite complicated.

[0003] A search revealed that existing glass-lined reactors are mostly large-scale production reactors, including our company's patent technology (CN113694853A) for a glass-lined container with magnetic stirring and (CN109569472B) for a high-pressure corrosion-resistant glass-lined reactor. A common drawback in their use is that in factory production, if chemical reagents need to be synthesized using a glass-lined reactor, a reagent formula is required first, followed by synthesis. Preliminary testing and verification of the formula are also necessary. Directly conducting these processes in large reactors, as described above, leads to significant resource waste if the preliminary testing fails. Therefore, to avoid excessive waste, a specially designed small-scale experimental glass-lined reactor can solve this problem. Using an experimental glass-lined reactor for verification and preparation reduces resource waste even if the reagents are substandard.

[0004] This solution provides a small high-pressure glass-lined reactor. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a miniaturized high-pressure glass-lined experimental reactor. It can utilize its small volume to adjust and verify reagents, avoiding serious waste of resources. At the same time, the groove on the fixed flange makes the fixation between the tank body and the tank cover more secure and the seal tighter, and also avoids the glaze layer from being damaged due to high pressure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A miniaturized experimental high-pressure glass-lined reactor includes a tank body and a tank cover. Fixed flanges are provided at the ports of the tank body and the tank cover, and bolt through holes are provided on the fixed flanges. Bolts are used to securely connect the tank body and the tank cover through the bolt through holes. A first high-diameter flange is provided on the tank cover, and a mounting bracket is fixed to the first high-diameter flange by bolts. A double-end mechanical seal is provided inside the mounting bracket, and a gasket is provided between the double-end mechanical seal and the first high-diameter flange. The double-end mechanical seal is fixed to the first high-diameter flange by bolts. A feed inlet is provided on the tank cover, and the feed inlet is angled to ensure that it does not interfere with the first high-diameter flange. A high-diameter flange is provided at the feed inlet. A motor is provided on the mounting bracket, and a stirring assembly is provided at the end of the motor shaft. The stirring assembly is located inside the tank body. A discharge port is provided at the bottom of the tank body, and a second high-diameter flange is provided at the discharge port.

[0008] The fixed flange end face is provided with a groove; the bolt through hole is provided in the grooved part of the fixed flange.

[0009] The mounting bracket is equipped with a balance tank, which is connected to a double-end mechanical seal to control the pressure inside the balance tank.

[0010] A sealing gasket is provided between the end faces of the fixed flange on the tank body and the fixed flange on the tank cover, which can prevent liquid from flowing out of the tank body when the tank body and tank cover are fixed.

[0011] Preferably, the stirring assembly includes a stirring shaft and a stirring arm mounted on the stirring shaft. The stirring shaft is connected to a motor shaft and passes through a double-end mechanical seal and a first high-diameter flange into the tank. The double-end mechanical seal provides a sealing function and also stabilizes the rotation trajectory of the stirring shaft. The stirring effect is achieved by the motor driving the stirring shaft to rotate.

[0012] Preferably, the outer wall of the tank is provided with a jacket, and the jacket is provided with a liquid inlet and a liquid outlet; the heating medium enters and exits through the liquid inlet and the liquid outlet for heating.

[0013] Preferably, the heating medium is one of heating steam or heating oil.

[0014] Preferably, the tank body is provided with a mounting plate at the fixed flange for fixing the tank body.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] The high-pressure glass-lined reactor in this design serves as a small-scale experimental reactor, enabling the verification and experimentation of reagent formulations with minimal material usage. Using conventional production reactors for experimental preparation would result in significant material waste during the experiment. This small-scale experimental reactor avoids this drawback and improves experimental efficiency. Furthermore, when manufacturing the experimental reactor, a slanted inlet design, rather than a horizontal one, ensures smooth material entry. The first high-diameter flange is also designed to avoid interference with the high-diameter flange at the inlet. Additionally, the groove on the flange end face is used for bolt installation. This groove not only eliminates the need for a glaze layer, reducing the amount of base and top glaze used, but also prevents excessive bolt tightening that could cause the glaze layer at the flange end to crack.
