Dual-chamber lime vertical kiln sealing feeding device and feeding method

Abstract

The invention relates to a dual-chamber lime vertical kiln sealing feeding device and a feeding method. The dual-chamber lime vertical kiln sealing feeding device comprises a frame, guide rails at two sides, a motor drive system, a hopper, a top cover hydraulic system and a feeding device hydraulic system, wherein the top cover hydraulic system is arranged in the frame and connected with a top cover of the hopper; the motor drive system is arranged in the middle of the frame, and a main shaft connected with the motor drive system is connected to the middle of the hopper and a bottom discharging conical body; the feeding device hydraulic system is arranged at two sides of the guide rails and is connected with the frame, so the whole frame downwards moves to a discharging position along the guide rails to prepare feeding, and a guide support arranged around the lower part of the hopper is used for guiding the downward moving process; and the bottom discharging conical body is positioned at the bottom of the hopper to seal the outlet of the hopper. A seal feeding device is arranged on the top of the dual chamber lime vertical kiln, no air and dust leakage exists in the feeding process, good sealing effect is ensured, the energy consumption is lowered, on line feeding can be performed anytime, the dual chamber lime vertical kiln is upsized, and the environment protecting demand of the dual chamber lime vertical kiln in the project construction process is met.

Description

technical field [0001] The invention relates to a lime kiln, and relates to a high-temperature-resistant sealed feeding device for the lime kiln, in particular to a sealed feeding device and a feeding method for a double-chambered lime shaft kiln, which can be used for top sealed feeding and other sealed feeding of active lime double-chambered shaft kilns. Background technique [0002] Compared with other active lime kilns, the double-chamber vertical kiln currently in use has the lowest energy consumption and a high degree of automation, and is gradually becoming the mainstream lime kiln. At present, for double-chambered vertical kilns with a daily output of 600 tons and above, the kiln roof feeding devices of the two kiln chambers are basically open. This form has some defects, and its shortcomings mainly include the following aspects: [0003] 1. When feeding the kiln top, it will cause part of the hot flue gas inside the kiln to overflow, thus increasing the energy consu...

AI Technical Summary

Problems solved by technology

[0003] 1. When feeding the kiln top, it will cause part of the hot flue gas inside the kiln to overflow, thus increasing the energy consumption

[0004] 2. Exhaust gas and dust will overflow with hot flue gas, causing environmental pollution

[0005] 3. The kiln chamber being calcined in the two kiln chambers cannot be fed, which limits the feeding time, thereby reducing the utilization factor of the unit volume in the kiln chamber
