An automatic unloading device for a vertical lime kiln

Abstract

This utility model discloses an automatic unloading device for a vertical lime kiln, including an anti-blocking receiving mechanism, a self-starting door opening and closing mechanism, a moving mechanism, and a feeding mechanism installed on the anti-blocking receiving mechanism. A baffle is fixedly installed on the top surface of the receiving box. This automatic unloading device for a vertical lime kiln drives the receiving box to move to the left by starting the drive wheel. It pushes the sliding door through the lime kiln outlet, causing the sliding door to move and compress the spring. When the receiving box is below the lime kiln outlet, the lime kiln feeding device is activated, and the material enters the receiving box. At the same time, the drive motor is started to drive the stirring blade to rotate, performing an anti-blocking operation on the material entering the receiving box. After the material in the left receiving box is completed, the same operation is performed to fill the right receiving box with material. At the same time, the electric push rod on the left is activated to drive the first and second active connecting rods to adjust the angle, thereby opening the cover. The operator pushes the receiving trolley to the bottom of the receiving box to receive the material.

Description

Technical Field

[0001] This utility model relates to the field of vertical lime kiln technology, specifically to an automatic unloading device for a vertical lime kiln. Background Technology

[0002] A vertical lime kiln is a type of equipment used to produce quicklime. It has a relatively compact structure and small footprint, and is typically used for small to medium-sized production. During operation, limestone (mainly calcium carbonate) is fed into the kiln and heated by burning fuel (such as coal, oil, or gas), causing the calcium carbonate to decompose into calcium oxide and carbon dioxide. Vertical lime kilns have high thermal efficiency because the vertical layout allows hot air to rise, concentrating the heat generated by combustion onto the material, thus improving heat utilization. This type of vertical lime kiln is suitable for small businesses or regional production, especially in areas with convenient heat and fuel supply. However, existing automatic unloading devices for vertical lime kilns still have certain shortcomings. While traditional automatic unloading devices for vertical lime kilns can be used effectively, they cannot continuously discharge material, and they lack anti-blocking mechanisms when material falls into the receiving trolley, easily causing blockages. This increases the user's workload, reduces equipment efficiency, and frequently troubles users. Utility Model Content
