Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide kilns, in particular to a leakage prevention mechanism for a zinc oxide kiln. Background Technique

[0002] Zinc oxide is an important chemical material, which is widely used in the fields of chemical industry, medicine, cosmetics, etc. During its production process, a kiln is required for high-temperature calcination to obtain high-purity zinc oxide products. Generally, a lead-out pipe is installed above the zinc oxide kiln to lead out zinc vapor and zinc oxide powder from the volatilization channel of the kiln through the lead-out pipe, and then zinc oxide is collected.

[0003] According to the leakage prevention mechanism for a zinc oxide kiln with the publication number CN218178632U, it includes a zinc oxide kiln body. The top of the zinc oxide kiln body is fixedly communicated with a lead-out pipe, and the top of the lead-out pipe is fixedly connected with a transfer pipe. The leakage prevention mechanism is installed at the connection between the lead-out pipe and the transfer pipe. In the utility model, through the arranged leakage prevention mechanism and detection and alarm device, when leakage occurs at the connection of the zinc oxide kiln pipeline, an alarm can be given in time, and the leakage point can be blocked to prevent leakage. The detection reaction speed is fast, and there will be no continuous leakage situation, thereby improving the use safety of the zinc oxide kiln.

[0004] Through the above leakage prevention mechanism and detection and alarm device, when leakage occurs at the connection of the zinc oxide kiln pipeline, an alarm can be given in time, and the leakage point can be blocked. However, after the piston is used for a period of time, the sealing performance between the piston and the detection pipe is likely to decrease, thus causing a gap. If the replacement is not timely, it is easy for zinc vapor and zinc oxide powder to escape from the through hole, resulting in a leakage situation. Content of the Utility Model
