KD-RFL700A/B Four-wheel model hydraulic double-cylinder pre-heater is a trailer type melting facility, which equips with pneumatic (or hydraulic)brake, warning light whose flicker frequency can be flexibly adjusted and low temperature combustion device which ensures fully burning liquefied gas. The aims of developing this machine are to reduce the quantities of construction vehicles and operators, reduce construction cost, improve work efficiency and construction safety and avoid the trouble with loading and unloading the pre-heater for users. 1. Engine: 18HP water-cooled or air-cooled electric starting diesel engine. 2. Stirring: Diesel engine drives stirrer to run through gear pump, dual control valve, overflow valve and hydraulic motor. 3. Hydraulic oil tank: Tank is designed with windows, hot-spreading slice and indication of oil temperature, capacity is 50L, use 68# hydraulic oil. 4. Heating system: A type: Propane gas tank supplies gas to the imported stove in and outside igniter. The imported stove can save fuel by over 10% compared with traditional domestic stove; B Type: Infrared heating system or diesel heating system and can realize automatic setting and automatic controlling heating temperature. Compared with traditional heating stove, infrared heating stove can save fuel by over 60%, diesel injecting heating system can save fuel by over 20%, both have advantages of fast heating speed, high heating efficiency and more environmental protection etc. 5. Melting cylinder: It is made of special steel with scorch resistance, heating resistance and oxidation resistance, the bottom of melting cylinder is arc shape that is formed by stamping, inside is equipped with the erect type multi-vane hydraulic stirrer, Melting capacity is much more, and melting quality is much better. Capacity: 2*350Kg. 6. Thermometer: Each container is equipped with double imported conduction oil sensing thermometer with heating resistance and shock resistance, which makes displayed temperature more accurate and easily observe. 7. Operation control: The manual dual control valves respectively control two stirrers in the two cylinders to do positive and negative agitation. The patent anti-malicious and anti-irregular operation system can protect the machine from damage better. 8. Heating system: The conduction oil or high-tech filling heat preservation materials and multiple heat preservation system ensure much longer heating preservation time and consuming much less fuel, and efficiently melting. 9. Ventilating exhaust system: There are four suction-type chimneys at the top of cylinder, which can fully discharge smoke and dust produced by burning. 10. Discharge outlet: Lockable discharge trough and the close intermeshing type discharge system ensure open and shut more safety, accurate and convenient. 11. Structure: Integrative welding structure with high strength and heating resistance. Outer covering is made of cold-rolled high strength steel with oxidation resistance and heating resistance, whose surface has been coated by abrasion resistance and heating resistance spraying treatment. The pedal plate is made of anti -skid steel sheet. 12. Safety device: Equip with overload automatic protective device that make stirring automatically breaks away in emergency, and fire extinguisher and lighting devices ensure the safety of the operator and equipment. 13. Size & Weight: 4500mm (L) x1880mm (W) x2280mm (H), 2200kg.
