XD/XDZ Chain Bucket Unloader

key word:Heat exchange element


Product description

XD series Chain Bucket Unloader

 

1. Introduction

1.1. Purpose

XD series chain bucket unloader is one of the main unloading equipment specially designed for small and medium-sized thermal power plants

As the auxiliary unloading equipment of large thermal power plant and the loading and unloading of bulk materials in other industries.

1.2. Model meaning

XD-**/##

X -- unloading machine

D ------ bucket type

** ------- span (m)

##--------Rated output (T / h)

XDZ**

X -- unloading machine

D ------ bucket type

Z ----------- rotation (referring to inclined belt conveyor)

**------------ span (m)

1.3. Structural characteristics

The equipment consists of lifting mechanism, tipper mechanism, horizontal belt conveyor, inclined belt conveyor, belt luffing mechanism, crane traveling mechanism, electrical control and metal structure. It adopts 8-wheel walking, with great adhesion and stable operation. The inclined belt conveyor has the functions of horizontal rotation (90 °) and vertical luffing (40 °), which expands the adaptability and operation range of the chain bucket unloader. The operating system is set in a closed and forced ventilation operating room, with good working conditions. The equipment is divided into single span, double span and Sanyun according to the Cross railway line. It has a wide range of operation and large production capacity, especially for the raw coal with small particle size and good looseness, with high efficiency. The improved equipment can also discharge wet coal with moisture content of 30%.

1.4. Working principle

The equipment is to use the rotating chain bucket to lift the coal from the car body to a certain height and unload it on the horizontal belt conveyor, and then transfer it to the inclined belt conveyor. The inclined belt conveyor will throw the material on one side of the track. The unloading machine can be operated on a large site through crane traveling and inclining belt conveyor luffing.
