Product description

QYG impeller coal feeder

 

1. Introduction

1.1. Purpose

Impeller coal feeder is suitable for slot coal groove of thermal power plant. Through the rotation of impeller and longitudinal movement of car body, raw coal is transferred to coal conveying belt quantitatively, evenly and continuously. This machine is also suitable for conveying bulk materials in coal, metallurgy, mining, building materials, chemical industry and other industries.

According to the needs of users, a new type of impeller coal feeder with suspended impeller structure (i.e. upper drive type) and swing type impeller structure was developed by breaking the original traditional structure (i.e. lower drive).

Each series of products have novel structure, complete performance, and locked rotor protection device to ensure the safe operation of the equipment. The walking mechanism adopts the third generation wheel group with simple structure and convenient installation and maintenance. According to the needs of users, it can be equipped with water tank and water tank spray mist dust removal device, which can effectively protect the field operation environment.

1.2. Model meaning

         *-YG-##

         * ------- q is bridge type, M is portal type

         YG --- impeller coal feeder (SG is up drive impeller coal feeder)

         ##-------Output (T / h)

1.3. Main features

1.3.1. Characteristics of each series of products.

① Stepless speed regulation, continuous adjustment of coal supply at any time.

② Can be in place or before and after walking coal, no empty travel.

③ It can be operated or controlled remotely.

④ No dust flying, good for environmental protection.

1.3.2. Lower drive impeller coal feeder. The main drive mechanism of impeller is under the impeller, so it is called lower drive. On the basis of the traditional structure, the transmission system, frame structure, main and auxiliary coal scuttles and walking mechanism have been greatly improved to make the whole machine structure reasonable in shopping, increase the strength and rigidity of the frame, and avoid coal blocking and spreading, and the installation and maintenance are simple and convenient.

1.3.3. Upper drive impeller coal feeder. The main drive mechanism of the impeller is above the impeller, that is, the impeller is suspended under the main transmission mechanism, so it is called upper transmission. The impeller of the machine adopts the hanging type, which makes the layout of the coal feeding system and the main and auxiliary coal scuttles more reasonable, no coal blocking, no coal scattering, no foreign matter winding in the main shaft, and the installation and maintenance are more convenient.
