Product Details

Sodium fluoride chemical hollow paddle dryer


Project description:
  Coating industry for phosphating accelerator, so that the phosphating solution stability, phosphating refinement, improved phosphate film performance. Aluminum and its alloys in the phosphating, the closure of a highly harmful negative catalytic role of Al3 +, so that the smooth phosphating. Wood preservatives, agricultural pesticides, brewing fungicides, pharmaceutical preservatives, welding flux, alkaline zincate galvanized additives and enamel, paper and so on.


  First, the principle of Sodium fluoride chemical hollow paddle dryer:
 There are wedge-shaped hollow paddles in hollow axis,and heat medium is from-40℃ to 320℃, the heat medium is steam or hot air or heat conduction oil and so on.The heat medium (such as steam or thermal oil) will flow into chamber jacket and hollow mixing axis through rotary join. Hollow mixing axis has different inner structures according to different types of heat medium, which will ensure of best heat transfer efficient.

The equipment heats up, cools, and agitates make it can fulfill the following unit operations: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), reaction and sterilization. Stirring blade is also a heat transfer surface, so that the heat transfer area within the unit effective volume increases, shortening the processing time. Wedge-type blade heat transfer surface has a self-cleaning function. The compression-swell function makes the material mix evenly. Material moves along the axial into the "piston flow", in the axial section, the material temperature, humidity, mixing gradient is very small.

  Second, the characteristics of Sodium fluoride chemical hollow paddle dryer:

1. Compact structure: the main heat transfer components of the dryer is a shovel-shaped blade, these blades are dense, in accordance with the provisions of the interval cross-arranged in a fixed rotation axis, so the unit volume of heat transfer is relatively high. For this reason, the structure of this device is very compact, small space.

2. High heat transfer efficiency: As the raw materials are well mixed, due to the relative rotation of the spade of the blade and the tilt of the blade surface and the body heating and cooling, to ensure that all the contact with the product surface can be evenly transmitted heat.

3. Self-cleaning performance: As the movement of the blade is relatively rotating, they are on the inner surface of the continuous self-cleaning effect. The products that are intertwined and stacked on the blades can be removed and re-enter the production process.

4. Simple control: drying process and residence time can be simply checked, controlled and adjusted. They can be set and adjusted individually based on the physical properties of the dried product. The number of shafts or blades, the speed, the temperature and the drying time of the heat transfer body are also can be set and adjusted.

5. Less dust and odor: due to the drying process use very samll air flow, so it produces very few dust and odor. Therefore, with its supporting the use of vacuum cleaner or deodorant is also small or not need to use them.

6. Suitable for drying large humidity products: the use of the paddle-type drying elements and continuous mixing, can dry large viscosity, high humidity materials. Its structural design avoids the accumulation of products at dead ends and the overheating or corruption caused by product retention.

7. Almost no wear and material loss: the blade speed is very low, only 10 to 40 rotations per minute, which effectively avoids the abrasion and abrasion caused by the rapid wear and tear of the machine tool. In addition, the risk of rupture of metallic materials is minimized.
