Description

Technical Field

[0001] The utility model relates to the technical field of discharge devices, in particular to a safety discharge device. Background Art

[0002] A safety relief device is a device that automatically activates in emergency or abnormal situations during chemical production to prevent pressure-bearing equipment failure due to overpressure in the internal fluid medium. For example, in a reactor, if thermal runaway occurs, the safety relief device can effectively control pressure through steam, gas, or a combination of these releases, preventing overpressure accidents.

[0003] The prior art publication number is CN221245171U, which is a closed curved-blade disc turbine reactor, comprising a reactor body, a sealing top cover being provided at the top of the reactor body, two pressure relief valves being fixedly installed at the top of the sealing top cover, and a plurality of heating resistance wires being fixedly installed inside the inner wall of the reactor body.

[0004] The reactor is provided with a pressure relief valve. During use, the pressure relief operation is performed only through this single pressure relief valve. If the pressure relief valve is damaged during the use of the reactor, the reactor will be unable to perform the pressure relief operation or will be in a pressure relief state all the time, resulting in the pressure not being able to be released in time or the pressure being in a continuously decreasing state. This not only poses certain safety hazards, but also affects the reaction of the internal materials. For this reason, improvements are proposed. Utility Model Content

The setting of the two fixed blocks is conducive to the installation of the switching assembly.

[0011] Furthermore, sliding grooves are provided on the inner walls on both sides of the fixing seat, and the sliding grooves are slidably connected to the mounting seat. The sliding grooves have a limiting effect on the mounting seat, which can ensure the stability of the movement of the mounting seat.

[0013] Furthermore, travel switches are fixedly installed on the inner walls on both sides of the fixed seat, and the travel switches are matched with the auxiliary blocks.
