Description

Technical Field

[0001] This utility model belongs to the field of leakage collection technology for stirred tanks, specifically relating to a top-mounted leakage collection device for stirred tanks. Background Technology

[0002] A stirred tank is a container used for physical or chemical reactions. It mainly uses an internal stirrer to mix the materials inside the container, ensuring sufficient contact and reaction. It typically consists of two parts: the tank body and the stirring assembly. The stirring assembly includes a stirring motor, a stirring shaft, and stirring blades. The top of the stirring shaft penetrates the tank body. One end of the stirring shaft inside the tank body is fixedly connected to the stirring blades, while the other end outside the tank body is connected to the output shaft of the stirring motor. The stirring motor drives the stirring shaft to rotate, thus achieving the purpose of mixing the materials inside the container. When the stirred tank needs to maintain a set pressure during use, the connection between the stirring shaft and the tank body usually needs to be sealed.

[0003] In the existing technology, the stirring shaft of the mixing vessel is mostly sealed by mechanical seal. Although mechanical seal can seal and limit the movement of the stirring shaft, after long-term use, it is easily affected by environmental factors such as external impact, dust, high temperature, high pressure and equipment factors such as mechanical vibration, resulting in leakage of sealing fluid or aging of the sealing ring. Since there is no corresponding collection device between the mechanical seal and the vessel body, the leaked sealing fluid or the detached sealing ring debris can enter the vessel body through the gap between the stirring shaft and the vessel body, thereby contaminating the material inside the vessel.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a top-mounted stirring tank internal leakage collection device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The observation window 310 is a transparent observation plate, which facilitates the observation and judgment of the internal condition of the collecting connecting section 302 through the observation window 310.

[0051] In practical use, the stirring shaft 202 is sealed and assembled by the mechanical seal 204 and the mounting bottom cover 203. The stirring shaft 202 is driven to rotate by controlling the operation of the stirring motor 205. During the rotation of the stirring shaft 202, the stirring blades can be rotated, and the materials in the vessel 1 are mixed and stirred by the rotation of the stirring blades.

[0052] When the mechanical seal 204 leaks sealing fluid or sealing ring debris, the leaked sealing fluid or sealing ring debris can be collected by the cooperation of the collecting connecting joint 302 and the mounting chassis 301. At the same time, the stirring shaft 202 can be sealed and protected by the cooperation of the packing cylinder 303, the packing gland 305 and the sealing packing 306, so that the sealing fluid or sealing ring debris is collected into the collecting connecting joint 302 under the guiding action of the packing cylinder 303 and the packing gland 305.

[0053] Meanwhile, the collection of sealing fluid or sealing ring debris in the collecting joint 302 can be observed and judged through the observation window 310.
