Installation of enamel reaction kettle and adjustment of mechanical seal

Thread Content

1. Place the reactor on the pre-prepared platform, adjust its overall levelness, and secure it firmly to the platform. 2. Stirrer installation: Open the reactor’s lid and lift it 600–700 mm above the lower part of the reactor, then carefully place the stirrer inside the reactor. Then slowly lower the tank lid; the stirrer shaft extends out from the opening in the center of the lid, after which the lid is secured to the lower part of the reactor. Note: The stirrer must not touch the mouth of the enamel tube. 3. Installation of the mechanical seal: The mechanical seal consists of two parts – 1: the rotating ring (black, graphite-like in appearance), 2: the stationary ring (white ceramic ring). Both of these parts are required to work together with the enamel water jacket to provide a seal. Remove the static ring and the enamel water jacket, then take out the black pressing plate inside the enamel water jacket. Place the white ceramic static ring under the pressing plate, with the protrusion of the ceramic ring facing upward, and then fix the pressing plate in place. 4. After fixing the ceramic static ring to the pressure plate, the enamel water jacket is then fixed at the central pipe opening on the reactor lid; the stirrer passes through the middle of the enamel water jacket and is secured at the central pipe opening using a swivel flange, with the screws being pre-tightened. 5. Remove the moving ring with the boss facing downward and thread it onto the stirrer (this should be done after removing the lock nut on the stirrer shaft), then adjust the tightness using the tightening bolt on the moving ring. 6. Cut the retaining ring inside the locknut in half, and fix it in the keyway of the output shaft on the reducer bracket; the locknut is placed on top of it, with the retaining ring serving to support the locknut. 7. Installing the reducer: First, prepare four 150mm screws; those for capacities of 500L or less use M20 threads, while those for higher capacities use M24 threads. Also, provide 16 appropriate nuts. To be used as an adjustment bolt. There are four support points on the reactor tank lid, which are the locations where the adjustment bolts are placed. How to place it: Take a screw rod and insert it into the central hole of the support point. Four nuts are required to form the adjustment bolt – one nut is installed below the hole, and two nuts are installed above it. Once all four adjustment bolts have been installed, the reducer can be installed. 8. Pass the four mounting and positioning holes under the reducer bracket through the adjustment bolts. Once completed, tighten the final nut on the adjustment bolt, connect the mixer to the output shaft of the reducer; after a secure connection is established, secure the locknut to the mixer. Then, the levelness of the reducer is adjusted by changing the distance between the two middle nuts. Once the levelness has been adjusted, tighten all the screws. Then use the hand to turn the stirrer and check whether it rubs against the pipe opening, the enamel water jacket, and the static ring (the gap between the stirrer and these components can be adjusted by modifying the slip flange that holds the enamel water jacket in place). Adjust the gap between them during mixing by adjusting the static ring pressure plate; once the gap is set, secure it with bolts. 9. Mechanical seal adjustment: Bring the rotating ring into tight fit with the stationary ring (the spring on the rotating ring should be pre-tensed to a distance of 3–5 mm); then secure the adjustment bolts on the rotating ring to ensure a tight seal between it and the stationary ring, fixing it in place on the stirrer. 10. Once the reaction vessel installation is complete, start the trial operation. Turn on the power supply, start the motor intermittently, and check the rotation direction of the mixer (clockwise when viewed from above is the correct direction). With these steps, the installation of the drive mechanism for the reaction kettle is complete. During installation, be sure to avoid any contact with the enamel surface.
