1. Overview:
The working principle of the HG series drum dryer is to allow liquid or slurry materials to form a thin film on the drum surface heated by water vapor or other heat carriers. The drying is completed during one rotation of the drum. The product is scraped off with a scraper, and the exposed drum surface contacts the raw material again and forms a thin film for drying.
(1) Steam is used as the heat source, with a large heating area, high thermal efficiency, and uniform heating. (2) The drying rate is high, and the heat and mass transfer process of the wet material film on the drum wall is consistent from the inside to the outside, with a large temperature gradient, so that the surface of the material film maintains a high evaporation temperature. (3) The drying time is short, about 10-15S, suitable for heat-sensitive materials. (4) Easy to operate and maintain.
HG series drum dryer is composed of main drum, frame, feeding device (upper feeding or lower soaking), driving mechanism, spiral feeding device, dust collecting device, scraper device and other components.
Drum scraper dryer is a liquid or slurry forming and drying equipment. It can cool and crystallize high-temperature saturated salt solution into solid flakes, or heat and dry slurry into solid flakes. It cools or heats through the cylinder wall, has high heat transfer efficiency, and is an ideal equipment for crystallization in continuous production lines. The machine has a compact structure and is easy to operate.
2. Components:
This equipment mainly consists of a rotatable hollow cylinder, a scraper and a clamping device, cooling water (heating medium) inlet and outlet pipes, a transmission system, a frame, and control electrical appliances.
3. Electrical control:
Drum scraper dryer uses an electromagnetic speed regulating motor (or variable frequency motor) to adjust the drum speed according to the production and product quality requirements.
4. Safety technical operating procedures:
Before using this machine, you should read the entire instruction manual and then turn it on.
Start the machine:
⑴ First check whether there is oil in the motor reduction gearbox and whether the wires are connected reliably.
⑵ Whether the pipeline is connected reliably.
⑶ Whether the material tank is clean and free of debris.
⑷ Whether the steam (heat transfer oil) pipeline is connected reliably.
After the above inspections are completed, turn on the main power supply and turn on the buttons on the control panel. Check whether the motor direction at each point is correct.
⑴ Turn on the main power switch in the control cabinet and press the main power button on the panel.
⑵ Press the main motor button of the drum dryer to listen to the sound of the motor running and whether the drum runs smoothly and normally. Note that the scraper should be separated from the drum before turning on the rotating motor.
⑶ Open the steam valve to the set pressure (≤0.6Mpa). Preheat the drum for 2 to 3 hours, so that the drum expands evenly as a whole, and then open the steam heating valve (≤0.2Mpa) of the exhaust hood and the feeding tank.
⑷ Slowly move the scraper against the drum, and adjust the fine-tuning bolt according to the interval to make the scraper close to the drum without damaging the surface of the drum.
⑸ Open the dehumidification fan and the slurry feed valve at the same time to control the feeding speed.
Open the splash shaft and adjust the speed to evenly distribute the material.
⑹ Adjust the pressure of the scraper again according to the material sticking situation so that the material on the drum surface can be scraped off smoothly, but do not be too tight to damage the drum surface.
(7) Open the discharging cage and the discharging fan.
(8) Check whether the drum end surface is clean. Check whether the material level is normal and adjust the feed amount according to the liquid level.
Shutdown:
⑴ First turn off the slurry feed valve.
⑵ Turn off all steam inlet valves.
⑶ Turn off the splasher.
(4) When the material on the drum surface is scraped clean, turn off the main motor power, the exhaust fan, the discharging cage and the discharging fan.
(5) Clean the site.
Before installing the equipment, all installation components should be fully inspected, and the flatness of the foot should be less than 2/1000.
Installation should be arranged according to the general layout. The ground should be flat and the steam pipe (heat transfer oil) should be installed. A pressure reducing valve and a pressure gauge should be installed at the inlet. The steam inlet flanges should be firmly connected.
Turn the main motor to observe whether the main drum is turning correctly.
Observe whether the main drum and each transmission component rotate flexibly, whether the steam inlet and outlet are connected, and whether the pressure gauge is within the working pressure range.
Start the motor, the main drum runs smoothly, and after the temperature rises, adjust the motor speed and the uniformity of the material film on the drum after adding the material to control the final moisture content of the material.
Start the auger motor to output the dried finished material, and adjust the auger motor speed according to the amount of dried finished products.
Precautions
1. Operators must stick to their posts and concentrate their minds.
2. Before starting, check whether the power supply is normal and observe the three-phase voltage through voltage switching.
3. The buttons on the operation panel must be operated in the order of the operating procedures.
Maintenance and overhaul
1. After the equipment has been running for a period of time, the scraper clamping force should be adjusted.
2. The lubricating oil of each reducer should be replaced every six months, and the lubricating oil of the main shaft bearing should be replaced regularly.
3. When the equipment is not used for a long time, all the remaining materials in the trough should be cleaned to prevent the materials from being hard and difficult to remove, which will affect future use.
4. Regularly check the flexibility of the rotating parts and whether there is any jamming. Gears and other parts should be regularly greased, and the errors of measuring devices such as pressure gauges should be regularly corrected. (V-belt transmission parts with severe wear should be replaced in time.)
5. For details on the maintenance of motors and reducers, please refer to the maintenance instructions for motors and reducers.
