Double-hearth kiln top feeding device

Abstract

The invention relates to the technical field of lime production, in particular to a double-hearth kiln top feeding device. The double-hearth kiln top feeding device comprises a reversible belt conveyor, a rotary feeding hopper, a liftable sleeve and a liftable charging bell; the reversible belt conveyor is placed in a sealed shell, the rotary feeding hopper comprises a fixed cover and a feeding hopper body, the fixed cover is fixedly connected to the two ends of the sealed shell, the feeding hopper body is located in the fixed cover, below the fixed cover and can rotate around the axis of thefeeding hopper body; the liftable sleeve is placed in the rotary feeding hopper, so that an outlet in the lower part of the rotary feeding hopper is closed; and the liftable charging bell is placed inthe liftable sleeve, so that the distribution of limestone in the kiln is adjusted. According to the double-hearth kiln top feeding device, functions of the reversible belt conveyor, the rotary lifting feeding hopper and a kiln hearth closing flashboard are integrated, investment is reduced, flying dust is reduced, and product quality is improved.

Description

technical field [0001] The invention relates to the technical field of lime production, in particular to a top charging device for a double-chamber kiln. Background technique [0002] At present, the feeding device on the top of the double-chamber kiln is usually: reversible belt conveyor + rotating lifting hopper + kiln chamber closing gate. Limestone is fed from the feeder to the reversible belt conveyor, and then through the forward rotation and Reverse, load and unload the limestone into the two rotating lifting hoppers, and then unload the limestone into two different kiln chambers of the double-chamber kiln through the lifting and rotating process of the rotating lifting hopper for calcination, and the kiln chamber closes the ram Cooperate with the lifting of the rotary lifting hopper to seal the kiln chamber. [0003] Using the above method, there are mainly problems in the following aspects: [0004] 1. The three kinds of equipment are set independently, and the ro...

AI Technical Summary

Problems solved by technology

[0004] 1. The three kinds of equipment are set independently, and the rotating and lifting feeding hopper needs lifting space, so the overall height of the kiln top feeding system is relatively high;

[0005] 2. The three kinds of equipment are set up independently, there is a lot of dust in the process of discharging between various equipment, and the production environment of the double-chamber kiln top is harsh

[0006] 3. The distribution of limestone on the kiln chamber section is not well controlled, and there is a lack of effective adjustment means
