Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief components, in particular to a pressure relief component used for distillation treatment of high-purity benzethonium chloride. Background Art

[0002] High-purity benzethonium chloride is a compound with high efficiency, broad spectrum and rapid bactericidal characteristics. This substance is easily soluble in water to form a foamy soapy solution, and can be dissolved in ethanol, acetone and chloroform. Due to these characteristics, it is widely used as a bactericidal disinfectant and preservative.

[0003] In the medical field, high-purity benzethonium chloride is often used as a disinfectant for skin and mucous membranes. It can effectively inhibit the growth of bacteria and improve inflammation of skin and mucous membranes, such as folliculitis, eczema and other diseases. At the same time, it can also be used to clean burn wounds, help disinfection and prevent infection. In addition, the drug can also be used to treat diseases such as vaginitis.

[0004] Distillation is a common step in the preparation of high-purity benzethonium chloride. Distillation is an important means of purifying and separating compounds, and is particularly critical for the preparation of high-purity benzethonium chloride. In the preparation process, the main purpose of distillation is to remove impurities and unreacted raw materials in the reaction mixture, thereby obtaining benzethonium chloride with higher purity. By controlling the distillation temperature, pressure and other conditions, the separation and purification of the compound can be effectively achieved.

[0005] In the prior art, when preparing high-purity benzethonium chloride, a common distillation device is generally used, but this distillation device does not have a pressure relief function. During the distillation process, as the temperature rises, the pressure in the system will gradually increase. In order to maintain the stability and safety of the distillation process and avoid equipment damage or danger, it is necessary to use a pressure relief valve and other devices to release the excessive pressure in time. In the general pressure relief device, the valve is in an open state during the pressure relief process. When the air pressure is balanced, the valve is closed by pressure balance. In this process, the valve closes slowly, which will cause some gas to reflux through the pressure relief valve, which will cause the purity of the prepared high-purity benzethonium chloride to decrease.

[0011] As a further description of the above technical solution: a breathable valve is arranged at the top of the collecting tank.

[0012] As a further description of the above technical solution: a one-way valve is arranged inside the output pipe.

[0013] The utility model provides a pressure relief component for high-purity benzethonium chloride distillation treatment. It has the following beneficial effects: during the distillation process, when the internal air pressure of the device is too large and exceeds a certain threshold, the gas enters the pressure relief pipe through the input pipe, pushing the baffle inside the pressure relief pipe to rotate, and when the baffle rotates to contact the block on the side wall, the gas is discharged through the output hole and the output pipe to achieve pressure relief, and when the pressure relief is completed, the internal and external air pressures are balanced, and at this time, under the action of the torsion spring, the shaft is quickly reset, and the baffle is reset to a vertical state, and when the internal air pressure decreases, the external gas pushes the baffle through the output pipe, under the action of the bottom end block, the baffle does not rotate, and the backflow phenomenon does not occur, and under the elastic action of the torsion spring, the baffle is reset relatively quickly to avoid the occurrence of the backflow phenomenon.

Two blocks are fixedly installed on the inner wall of the tube 7, one of which is arranged on the bottom wall inside the pressure relief tube 7, and the other block is arranged on the side wall inside the pressure relief tube 7 near the output hole 5. During the distillation process, when the internal air pressure of the device is too large and exceeds a certain threshold, the gas enters the pressure relief tube 7 through the input tube 3, pushing the baffle 9 inside the pressure relief tube 7 to rotate. When the baffle 9 rotates to contact the block on the side wall, the gas is discharged through the output hole 5 and the output tube 6 to achieve pressure relief.
