Description

Multi-channel rotary ash discharger

Technical Field

The utility model relates to a lime production technical field, concretely relates to rotatory ash hoist of multichannel.

Background

The ash discharging equipment of the lime kiln is key equipment for ensuring uniform discharging of the cross section of the shaft furnace, adjusting the shape of a roasting zone, stabilizing the trend of airflow in the kiln, crushing bonded materials, determining production capacity and influencing product quality. For a long time, the traditional lime discharging system of the domestic lime shaft furnace has certain limitation in production, and the traditional and commonly used discharging equipment comprises: a planet ash discharger, a support plate discharge machine, an inserting plate ash discharger, a tooth roller ash discharger, a fluted disc ash discharger, a vibration ash discharger and the like. The ash discharging device is applied to various simple kiln types in 60-70 years, particularly peripheral inserting plate type (or trailing plate type) ash discharging machines are applied to many, although peripheral multipoint discharging is realized by the ash discharging device, the stroke of the inserting plate is fixed and the discharging amount cannot be controlled because each discharging point adopts a single inserting plate or trailing plate for discharging, so that the discharging amounts of a plurality of ash outlets cannot be synchronously discharged, the problem that the material level in a furnace cannot be controlled and the material deviation is easily generated is caused, and meanwhile, the ash discharging device has the defects that the control points of the device are complicated and are easily damaged.

With the continuous improvement of the requirements of the production process, the various ash extractors are gradually eliminated in the beginning of the 90 s, and the application is few at present. The new type ash-discharging equipment has gradually replaced the old type ash-discharging machine, such as: disc type ash extractors, screw cone ash extractors and the like become mainstream devices. However, the following problems are continuously discovered during the use of these two devices:

the phenomenon of deviation of a tower-shaped spiral cone occurs for a long time in the using process of the spiral cone ash discharging machine, so that an ash tray arranged on the tower-shaped spiral cone collides with a furnace wall, the normal operation of equipment cannot be realized, and ash cannot be discharged normally. Meanwhile, the spiral ash discharging machine forcibly discharges ash by using a large-pitch single-phase rotating extrusion principle, only one ash discharging port is arranged because the spiral ash discharging machine can only rotate towards one direction, and the material surface is very easy to incline due to the smaller ash discharging port, so that slow or no blanking can be realized if the ash discharging port is blocked by nubs in operation, and the long-time shutdown inspection can not be finally realized due to the fact that the material discharging port is blocked by nubs. In addition, the structural defects formed by the installation of the equipment and the kiln body are not negligible, the whole equipment of the spiral ash discharging machine is required to be installed in a sealed structure of a civil engineering foundation at the bottom of the kiln, the installation of the equipment is required to wait for the whole spiral ash discharging machine to be placed in the civil engineering seal body and then the installation and the manufacture of a kiln body steel structure can be carried out, if the spiral ash discharging machine has an equipment accident, the construction can be carried out only in a narrow environment in the kiln foundation, the maintenance environment is extremely severe, the whole equipment cannot be transported out of the kiln for maintenance due to the structural characteristics of the equipment, even the equipment cannot be transported out of the kiln after being disassembled, and the 'one-time installation and the lifelong service' are the fatal defects of the spiral ash discharging machine.

The disc ash hoist is a new generation of equipment which is newly designed and researched according to different kiln type structures and different raw material fuel structures in China and is formed by optimizing design after partial defects of the spiral cone ash hoist are improved. However, the disc ash hoist only has a feed opening arranged at the center of the kiln bottom, and the disc ash hoist has the defects that the central feeding is fast, the peripheral feeding is slow, the discharging amount cannot be accurately controlled, the phenomenon of a material surface central funnel in the kiln is easily formed, and the raw and over-burning of lime products cannot be accurately controlled.
