Material Description:

The main component of diatomaceous earth is diatomaceous earth, which is a biogenic siliceous sedimentary rock mainly composed of the remains of ancient diatoms. Diatoms are a type of single celled algae that first appeared on Earth, living in seawater or lake water. They are extremely small in size and often grow and reproduce at astonishing rates. After billions of years, diatoms and other planktonic organisms have settled into diatom mud at the bottom of the water. Observing diatomaceous earth using an electron microscope, diatomaceous minerals are porous materials with pore sizes in the micrometer range. Their particle surfaces have countless tiny pores arranged in a regular and orderly manner in circular and needle shapes, with thousands of times more micropores per unit area than charcoal. This molecular sieve structure endows it with extremely strong physical adsorption and ion exchange properties. After precision processing, it is widely used in various fields such as alcohol and medical injection filtration, water purifiers, food additives, nuclear radiation adsorbents, etc; It can also slowly and continuously release negative oxygen ions, which can decompose harmful carcinogens such as formaldehyde, benzene, and radon gas.

Product Name: KJG Series Hollow Paddle Drying Machine

summary:

Wedge shaped hollow blades are densely arranged on the hollow shaft, and the heat medium flows through the blades through the hollow shaft. The heat transfer area within a unit effective volume is large, and the temperature of the heat medium ranges from -40 ℃ to 320 ℃. It can be steam or liquid, such as hot water, thermal oil, etc. Indirect conduction heating does not carry away heat with air, and the heat is used to heat the material. The heat loss is only the heat dissipation to the environment through the insulation layer of the device body. The wedge-shaped blade heat transfer surface has self-cleaning function. The relative motion between the material particles and the wedge-shaped surface produces a scrubbing effect, which can wash away the attached material on the wedge-shaped surface and maintain a clean heat transfer surface during operation. The shell of the blade dryer is W-shaped, and generally two to four hollow mixing shafts are arranged inside the shell. The shell has sealed end caps and upper caps to prevent material dust leakage and collect material solvent vapor. Set up a stopper at the discharge port to ensure the height of the material level, so that the heat transfer surface is covered by the material and fully functional. The heat medium flows through the shell jacket and hollow stirring shaft through the rotary joint. The hollow stirring shaft has different internal structures depending on the type of heat medium to ensure heat transfer efficiency.

Application:

The paddle dryer has been successfully used in fields such as food, chemical, petrochemical, dye, and industrial sludge. The characteristics of heat transfer, cooling, and stirring of the equipment enable it to perform the following unit operations: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), reaction, and sterilization. The stirring blade is also a heat transfer surface, which increases the heat transfer area per unit effective volume and shortens the processing time. The wedge-shaped blade heat transfer surface also has self-cleaning function. The compression expansion mixing function ensures uniform mixing of materials. The material moves in a 'piston flow' along the axial direction, and within the axial range, the temperature, humidity, and mixing gradient of the material are very small.
