Description

Technical Field

[0001] The invention belongs to the technical field of metering tanks, and in particular relates to a raw material additive metering tank for preparing a rubber liquid antioxidant. Background Art

[0002] Measuring tanks are commonly used in industry and laboratories to accurately measure and store liquids or gases. These tanks usually have precise scales to help users accurately measure the required liquid or gas. In laboratories, measuring tanks are often used to prepare solutions or dilute samples to ensure the accuracy and repeatability of experimental results. Rubber liquid antioxidant refers to a chemical substance added to rubber to reduce or inhibit the aging and deterioration of rubber caused by oxygen during long-term use. These antioxidants can usually extend the service life of rubber products and maintain the stability of their elasticity and physical properties. Existing metering tanks are generally divided into round and oval shapes. Compared with traditional round metering tanks, oval metering tanks have some obvious advantages in certain applications. They have high space utilization efficiency. The oval design can better adapt to the needs of limited space, especially in situations where they need to be installed in limited space, such as pipeline-intensive areas or factories with limited equipment layout. Reduce the risk of air and liquid mixing: Because the shape of the oval metering tank can help reduce the mixing of air in the fluid, this is particularly important for applications that require high-precision flow measurement. Less pressure loss: Compared with some other shapes of metering tanks, oval metering tanks can provide lower pressure loss, which helps improve the efficiency and energy utilization of fluid systems. More uniform fluid distribution, the oval design helps to distribute the fluid more evenly, reduce turbulence and eddy currents in the tank, and thus improve measurement accuracy. When the existing oval meter is used to store and measure raw materials, internal raw materials will precipitate and fall, and raw material crystals will precipitate on the inner wall, affecting the overall effect. At the same time, the existing rotating shaft often deviates during use. When used for a long time, the overall offset will occur, affecting the overall effect and service life.
