Product Details

  Project description:

  Painting industry for phosphating accelerator, the phosphating solution stability, phosphating refinement, improved phosphate film performance. Aluminum and its alloys in the phosphating, the closure of a great harm to the negative catalytic role of Al3 +, so that the smooth phosphine. Wood preservatives, agricultural pesticides, brewing fungicides, pharmaceutical preservatives, welding flux, alkaline zincate galvanized additives and enamel, paper industry.

  First, the principle of oxidized sodium fluoride dryer:

  Hollow shaft is packed with wedge-shaped hollow leaves, and the heat medium flows through the hollow shaft through the pulp. Unit effective volume within the heat transfer area is very large, heat medium temperature from 40 ℃ to 320 ℃, can be water vapor, it can be hot water or heat transfer oil. Heat transfer medium through the rotary joint, through the shell jacket and hollow mixing shaft, hollow mixing shaft according to the type of heat medium and have a different internal structure to ensure good heat transfer effect.

  The equipment heats up, cools, and agitates to complete 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 unit effective volume within the heat transfer area increases, shortening the processing time. Wedge-type blade heat transfer surface and has a self-cleaning function. The compression-expansion stir function makes the material mix evenly. Material along the axial into the "piston flow" movement, in the axial section, the material temperature, humidity, mixing gradient is very small.

Second, the characteristics of oxidized sodium fluoride 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 footprint.

2, high heat transfer efficiency: the raw material is very good continuous mixing, due to the relative rotation of the shovel-shaped blade and tilt the blade surface and the body heating, cooling, to ensure that all the surface contact with the product can be transmitted evenly Heat.

3, self-cleaning performance: 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-entered into the production process.

4, simple control: drying process and dwell time can be simply checked, control and adjustment. 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 set and adjusted.

5, the resulting dust and odor smaller: the drying process used in the gas flow is very small, so can produce dust and odor is also very small. Therefore, with its supporting the use of vacuum cleaner or deodorant is also small or no need to use.

6, suitable for large humidity products Drying: the use of the paddle-type drying elements and continuous mixing, can be a large viscosity, high humidity materials for drying. Its structural design avoids the accumulation of products at dead ends and overheating or spoilage due to product retention.

7, almost no wear and material loss: the blade speed is very low, only 10 to 40 per minute turn, which effectively avoids the abrasion and abrasion caused by the rapid wear and tear of the machine tool. In addition, the risk of fracture of metal materials is reduced.
