Portal And Semi Portal Type Scraper Reclaimer

Brief introduction of portal scraper reclaimer:

The portal scraper reclaimer is widely used in the storage yard of large enterprises such as mines, power plants, water conservancy, iron and steel, coking, cement, chemical industry, etc. it is used to scrape loose materials such as coal, ore powder, etc. it can be used for layered reclaiming according to the predetermined procedure after the stacker has piled up the standard material pile in the specified way. It has the characteristics of good homogenization effect, large stock yard reserves, small floor area and high degree of automation. It is the most advanced large-scale mixing process equipment in China at present. Its technical characteristics and automation level are first-class in China.

Working principle of portal scraper reclaimer:

The reclaimer adopts partition and layering reclaiming. Because there are coal retaining walls on both sides of each bin and the distance is short, the common process is the intermediate reclaiming process.

The reclaimer reclaims materials on the tracks on both sides of the yard, and moves back and forth. The materials are discharged into the guide trough through the scraper reclaiming system, and then transported out of the belt conveyor through the guide trough. After each layer of material is picked up by the reclaiming arm, the corresponding angle (i.e. the corresponding reclaiming depth) is lowered according to the preset command, and the material pile is taken out layer by layer under the set reclaiming speed. Unless there is shunting command in the reclaiming process, the material pile will be changed after all the materials in the reclaiming area of the silo are taken out.

Characteristics of portal scraper reclaimer:

1. The reclaimer is equipped with a boom made of thick and strong I-beam to ensure the strength of the boom and increase the transportation distance of materials;

2. The bulk material handling equipment is equipped with a variety of control methods to ensure flexible handling of bulk materials in different situations; 

3. Through simple installation and simple training process, a single employee can easily operate the equipment; 

4. Can adapt to the requirements of different yards, customized products for customers

5. SinomaLY has steel pretreatment production line, which can improve the corrosion resistance of structural parts and ensure the quality of all finished products. The use of large milling machine improves the machining accuracy of large parts. In the factory, the structure is assembled as a whole and the drive system is debugged.

6. SinomaLY uses high-performance new materials, such as wear-resistant materials and composites, to improve the durability of bulk material handling equipment.

7. Soft start and frequency conversion control are adopted to reduce the damage of reclaimer caused by serious impact. Protective measures are set on the equipment, which can be adjusted or stopped automatically in case of abnormal conditions.

Control Mode of Portal Scraper Reclaimer:                      

The reclaimer is equipped with three operation modes: automatic control, manual control and machine side (maintenance) control. The three operation modes are interlocked, that is, one of the operation modes is selected, and the other two operation modes are invalid.

1. Manual control

It can only be carried out on the console, and each part can be operated separately through the control button on the console. When the working condition switch is placed in the manual position, the automatic and machine side (maintenance) working conditions can not be cut in. The manual control can start and stop the scraper reclaiming system, winch lifting system (electric hoist), end beam walking and shunting system separately, and the interlocking between the systems is lost (the interlocking between cable reel and walking mechanism is reserved), but the protection of each system still works .            

2. Automatic control

The reclaiming operation under the automatic control mode can be implemented by the central control room and the on-board control room. When the central control room is required to control the reclaimer automatically, the operator only needs to press the automatic operation button on the console, and then press the start button, all the electrical equipment on the reclaimer will start according to the predetermined procedure, and the whole machine will be put into normal automatic operation. On the console of the central control room, the reclaimer system can be started or stopped by pressing the button.

3. Machine side (maintenance) operation

The local control is suitable for local action during installation, overhaul and maintenance, which depends on the operation button set beside the machine. In this control mode, the drive mechanism of the reclaimer can only be started or stopped independently after the interlock is released. When the working condition switch is placed at the machine side (maintenance) position, the automatic working condition and on-board manual working condition cannot be cut in. The on-board manual working condition also has the function of on-board manual working condition. However, the operation button is only installed in the position conducive to maintenance operation. Walking operation button is not installed under machine side condition.
