SF-280A “oil and electric” heating exchange single facer machine
Introduction
There are four heating method in the single face, steam heating, oil heating, electric heating, electric-oil exchange heating., SF-280A type electric heating oil exchange adopt electric heating pipe with heat conducting oil as medium, without boiler, the oil circulation inside the closed roller. Heat conductive oil carries high heat, less heat loss, no leakage, no pollution. The space is small, the maintenance cost is low, the heat transfer is uniform, the energy consumption is ordinary, and the board is of good quality. the average speed is 60-80 m/min, very suitable for small and medium enterprises.
| heating method | Average speed | character |
| Steam heating | 70-80 m/min | Need steam boiler. covers an area of large, Uniform heat transfer, good quality of cardboard. |
| Electric and oil exchange | 60-70 m/min | No need boiler. No pollution, small occupied space, low maintenance cost, uniform heat transfer, energy consumption in general, good quality of cardboard. |
| Oil heating | 40-60 m/min | pollution, covers an area of large, security risks, the efficiency is common, normal quality of the board. |
| Electric heating | 40-60 m/min | No pollution, small space, low maintenance cost, high energy consumption, uneven heating temperature, normal quality of cardboard, low efficiency. |
Advantage of oil and electric heating exchange single facer
1. Do not need the boiler, just use the preheat roller as a heating container, saving cost and save space.
2. No coal pollution.
3. Less heat loss, the whole closed loop, high heating efficiency.
4. The surface of the roller is heated evenly, the paper is more uniform heating. corrugated forming good.
Main specification
1. Mechanical speed: 100m/min.
2. Effective width: 1400mm-1800mm.
3. Adopt the hood type structure, with high pressure and powerful fan, and the air absorption and silencing equipment.
4. Wall cast iron structure. Independent gearbox, universal shaft drive.
5. The material of corrugated roller is 48CrMo alloy steel, which is tempered by adjustment, medium frequency quenching, surface polishing and chrome, the diameter of corrugated main roller is phi 280mm, the surface hardness HRC58 degree above.
6. Corrugated roller and pressure roller adopt airbag type pressure, cushion shock absorption, long service life.
7. Pneumatic control for glue, degumming. After the surface has been polished, it can be treated with the hard chromium plating after the surface of the grooves. The surface of the rubber roller has been polished and treated with hard chromium plating.
8.two or three of electric heat pipes are used to heat and heat the oil, heating fast, without heating furnace, automatic temperature control and control of two groups.
9. Strong closed-loop cycle of thermal conduction oil, low system pressure, no leakage, heat cycle utilization, less heat loss.
10.The rodent structure stirring ring is installed in the hot roller, the heat efficiency is high, the drum is hot and even, corrugated forming well.
11. The economical and environmental protection of the hot exchange single-side machine is small, which is especially suitable for small and medium-sized enterprises.
