Planetary tooth roller ash hoist

Abstract

A planetary tooth roller ash hoist comprises a motor, a coupler and a variable speed motor, wherein a main body is formed as follows: a tooth roller ash hoist is installed on a planetary ash hoist outside a lime kiln by a chute. The right end of a rotor shaft of the planetary ash hoist is connected with an output shaft of the variable speed motor by a chain, and the left end of the rotor shaft of the planetary ash hoist is connected with a rotor shaft of the tooth roller ash hoist by a chain. A motor sequentially drives the rotors of the planetary ash hoist and the tooth roller ash hoist to form a structure that the upper and low rotors rotate synchronously by the variable speed motor. According to the tooth roller ash hoist provided by the invention, a conventional tapered unloading machine is changed to be a tooth roller unloading machine, so that a novel structure is designed. The construction cost of the tooth roller ash hoist is **yuan only one fifteenth of a conventional machine; and the volume of the planetary ash hoist is reduced by 30%. The planetary tooth roller ash hoist is far away from dust and high-temperature working environment, the work performance of equipment is improved, the service life of the equipment is prolonged, and the working condition of maintenance workers is improved. The planetary tooth roller ash hoist serves as the special equipment for a lime shaft kiln, is reasonable in design, long in service life, low in construction cost, convenient to maintain and is well received by users.

Description

technical field [0001] The invention relates to an ash unloading device for a gas-fired lime shaft kiln, in particular to a star-shaped toothed roller ash unloader for a lime shaft kiln flue gas recovery carbon dioxide co-fired kiln. Background technique [0002] In the traditional production equipment of the lime shaft kiln, the screw cone ash unloader is set inside the lime shaft kiln body, the star type ash discharger is set outside the lime shaft kiln, the screw cone ash unloader and the star type ash discharger inside and outside the lime shaft kiln Connected by chute. Both the screw cone ash unloader and the star ash unloader are driven by a set of electric devices respectively arranged outside the lime shaft kiln. The disadvantages of the above-mentioned traditional lime shaft kiln production equipment are: a screw-cone ash unloader and a star-shaped ash unloader are divided into two independent parts and installed inside and outside the kiln respectively. This struc...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned traditional lime shaft kiln production equipment are: a screw-cone ash unloader and a star-shaped ash unloader are divided into two independent parts and installed inside and outside the kiln respectively. This structure not only increases the production area, but also is not conducive to Unified supervision and maintenance; 2. The screw cone ash unloader is installed in the lime shaft kiln, and has been working in the harsh environment of dust and high temperature in the kiln, which has a great impact on the safety and service life of the screw cone ash unloader. Big disadvantages, especially bring great inconvenience to daily maintenance and maintenance; 3. The traditional screw cone ash unloader has a large volume and the screw cone ash unloader is installed in the lime shaft kiln, which requires some Electric auxiliary installation facilities. The volume of these structures occupies a large production space in the lime shaft kiln. In order to ensure the normal production space of the lime shaft kiln, it is necessary to increase the construction space of the lime shaft kiln, resulting in the difficulty and cost of lime kiln construction. Increase; 4. The power unit of the screw cone ash unloader and the screw cone ash unloader are independently installed inside and outside the kiln, resulting in complicated structures, more related installation and connection accessories, and relatively large and cumbersome installation and connection. It also increases the cost

In addition to the increase in cost caused by the above reasons in the production of traditional lime shaft kilns, the cost of the screw cone ash unloader alone is nearly 300,000 yuan

In addition, the traditional star-shaped ash machine has an external dimension of Φ1100×620, which is large in size and occupies a large area.
