Principle structure:
The flap dryer is a drying machine based on the principle of bidirectional conveying. It is a versatile, highly adaptable, and continuous automatic dryer. It features a compact footprint and high drying efficiency. Moisture-containing materials flow from the rear of the dryer through a feed hopper onto the upper grating, which acts as a buffer and distribution mechanism for the material. The material then flows smoothly through the grating to the head of the dryer, where it flows through the flap mechanism to the lower level and back to the rear of the dryer. This cycle continues, drying the material gradually in hot air before it is discharged from the rear. Hot air can be configured to meet user requirements, including a separate hot air furnace or hot flue gas.
Product performance characteristics:
1. The guide rails utilize a light rail combination structure, optimized for material and fabric characteristics to ensure straightness and strength. The sprockets operate with minimal resistance, and the flap mechanism, coordinated with the guide rails, ensures smooth tilting of the flaps.
2. The sprockets utilize an automatic tensioning device, ensuring smooth chain operation. The well-coordinated guide rails effectively prevent chain dropouts, jams, and deviations.
3. The flaps are punched with a mesh pattern from heat-resistant steel, offering high strength, resistance to deformation, and excellent air permeability. Chain rollers are connected to both sides of the flaps, ensuring coaxiality and facilitating easy removal and installation.
4. The chain plates utilize electromagnetic or variable frequency drive, depending on the operating conditions, allowing for adjustable speed and controlled drying time.
5. Fire prevention devices are installed, with digital temperature sensors installed at the kiln head, center, and tail, for easy monitoring and control of the kiln temperature. A smoke damper is installed at the flue air inlet to immediately isolate the heat source and prevent fire in the event of a mechanical malfunction. 6. Based on the initial moisture content and characteristics of the material, either top-inlet or inter-layer air distribution is used to evenly distribute the hot air and effectively prevent cracking and bursting caused by rapid heating, thereby improving material quality and reducing breakage.
7. Depending on material moisture content and hot air temperature, choose between negative pressure induced draft and positive pressure forced draft.
8. A dedicated cleaning device is installed at the bottom of the equipment to remove dust particles, reducing usage intensity and preventing equipment failure.
Illustrate:
1. This equipment is non-standard and its dimensions are related to the following factors:
(1) Hot air temperature and humidity, as well as the way the hot air is generated
(2) Process interface considerations, whether the material is fed and discharged from one end or fed from one end and discharged from the other end
(3) Whether a powder cleaning device is required
(4) The height, length and width of the equipment can be changed according to the user's site conditions
(5) The structural form of the kiln
2. The power parameters of the equipment are related to the material properties, working conditions and layout form.
3. The equipment needs to be technically discussed before the solution can be determined.
