[0002] Neutralizers are a kind of substances widely used in chemistry, biology and other fields, which can react with specific substances to offset, inhibit or regulate their properties to achieve a specific purpose. At present, a constant-pressure dropping device is usually used in the production of neutralizers. The constant-pressure dropping device is a device that maintains the pressure stability of the dropping process in chemical experiments and industrial production, and ensures that the liquid can be dropped at a constant speed and quantity. It works by using the principle of communicating vessels and atmospheric pressure. When the liquid in the storage container is dropped through the dropping tube under the action of gravity, the volume of the container increases and the pressure decreases. The side glass tube is in communication with the atmosphere, which can supplement the gas in time to maintain the balance between the pressure in the container and the atmospheric pressure outside, and ensure that the liquid drops at a constant speed. However, when the constant-pressure dropping device is in use, foreign matters or other impurities in the external air can affect the original liquid in the storage container, which can interfere with the subsequent production of neutralizers and affect the quality of the neutralizers. Therefore, in order to solve the above problems, the application provides a constant-pressure dropping device for neutralizer production. CONTENT OF THE UTILITY MODEL
