The utility model provides a
chemical reaction tank quick replacement device, which comprises an operation panel, a six-way valve, an
optical fiber assembly, a reaction tank and a spring pressing mechanism, the front end of the six-way valve is butted with one end of the reaction tank through a first butting port, and the rear end of the six-way valve is tightly jacked by a first elastic
assembly, so that stable connection of an
optical path and a fluid channel is ensured; the liquid outlet end of the side wall of the reaction tank is communicated with the waste liquid head through a second
butt joint opening in the top of the spring pressing block and is vertically pressed and sealed by a second elastic
assembly, the device is suitable for
water quality and biological
medicine detection under high-temperature, high-pressure and strong-corrosive media, and the liquid leakage risk and the maintenance cost are reduced. Through spring elastic sealing,
corrosion-resistant materials, a full-light-shielding structure and unpowered
mechanical design, the problems that a traditional reaction tank is tedious in replacement, poor in sealing performance, prone to
corrosion, high in maintenance cost and the like are comprehensively solved, the reliability, safety and operation efficiency of a detection
system are remarkably improved, and online detection requirements under complex working conditions are met.
