First analysis of the reasons: leakage of the more reason is the sealing problem

A mixer on the feed side of the three-way funnel welded with a circle of sealing plate, it is a mixer with the feed between the sealing belt gap, the maximum gap of more than 50mm, this gap trimmed to 5mm or so. After a period of operation, due to the wear of the mixture, this gap will increase, each time downtime maintenance, the timely replacement or welding seal plate to ensure that the gap in the 5mm or so. This improvement is very effective in reducing leakage.

The first solution

After months of observation, it was found that the thickness of the adhesive in the dry powder mixer was related to the location of the water and the amount of water added. The thickness of the sticky material around the water point is small, and the thickness of the sticky material without the water point is large, the filling rate is seriously exceeded, the north side can add enough water and the thickness of the sticky material is relatively small.

In addition, in the process operation, the requirements of sintering ingredients do a good job of digestion work, to add enough water, so that the white ash in the digestion fully digested into a paste. It was observed that the thickness of the outer cylinder was evenly distributed along the length of the mixer and the thickness was less than or equal to 100 mm, indicating that the mixing point and the amount of water added to the southern end of the mixer had a greater effect on the thickness of the binder.

After studying the above situation, the original water pipe lengthened so that the entire cylinder along the length of the direction can be arranged to add water. At the same time, add a new water pipe to solve the problem of insufficient water at the southern end of the mixer. Mix the material into a mixer tube can be added when the water, so that the direction of the entire mixer to add water evenly, sticky material greatly reduced.

The second solution

Due to a mixer under the new 1,2 and the length of the belt machine is different, the location of the two three-way funnel wrong about 2m, so the new belt machine center line, had only with the two three-way funnel center Line parallel arrangement. Belt machine main, driven drum center distance of 8.3m, electric drum power 3kW, with speed 1.25m / s, belt width 650mm.

3, improve the water pipe

The third solution

The chute is fixed on the steel frame of the three-way funnel. The purpose of increasing the nozzle is to introduce the leaking mixture into the new chute, so as to avoid the leakage of the tires into the tire base, at the end of the new feed at the feed end of the mixer. The other end and the three links through the funnel, but taking into account the location of the three-way funnel and the new belt machine away from the mixture can not flow into the new belt machine, so according to the location of the space in the new chute And designed a small chute, while a mixed platform chisel a 400mm × 400mm square hole, install a funnel, will leak out of the mixture lead to the new belt machine.
