product details

Detailed introduction:

The main features of the ZXSH high-efficiency combined three cylinder dryer, also known as the three return dryer, are that it has a compact structure, occupies a small area, and occupies half of the area of a single cylinder dryer with the same output. It is reliable in operation, low in energy consumption, high in thermal efficiency, good in material drying effect, easy to achieve automation control, and requires fewer operators. Main purpose: The high-efficiency combination three cylinder dryer is mainly used to dry granular materials within a certain humidity range, such as yellow sand used in the dry powder mortar industry and various specifications of molding sand used in the casting industry. Blast furnace slag used in the building materials and cement industry. Small particle clay is used in the chemical industry for small particle materials that do not undergo chemical changes, are not afraid of high temperatures, and are not contaminated by smoke and dust. According to the requirements of different industries for the final moisture content of dried materials, the moisture content of dried materials can reach below 1-0.5%. The materials entering the dryer should not stick to the cylinder wall and lifting plate. The temperature of the gas entering the dryer for heat exchange should not exceed 750 degrees Celsius. If there are special requirements for high-temperature drying, the inner cylinder and poplar board at the inlet of the dryer can be made of heat-resistant steel plates.

Performance characteristics:

① The equipment investment is 20% of the imported products from abroad, made of wear-resistant manganese plates, which are 3-4 times more wear-resistant than ordinary steel plates The initial moisture content of the material is 15%, and the final moisture content is ensured to be below 0.5-1%. It is a product of various drying projects such as cement plant slag powder and dry powder mortar production lines Improved thermal efficiency by over 40% compared to traditional single drum dryers; ④ The fuel can be used for white coal, bituminous coal, coal gangue, oil, and steam. Capable of drying block, granular, and powdered materials below 20-40mm; ⑤ Reduce the footprint by about 60% compared to a single drum dryer. Reduce civil engineering investment by about 60% and facilitate installation; ⑥ No air leakage phenomenon, completely solving the sealing difficulty; ⑦ If the discharge temperature is ≤ 60 degrees, it can be directly fed into the material warehouse without the need for cooling in the cooling shed; ⑧ The temperature of the outer cylinder is ≤ 60 degrees, the temperature of the exhaust gas is ＜ 120 degrees, and the use time of the dust removal equipment bag is more than twice as long; ⑨ Coal consumption is 1/3 of that of a single drum dryer, saving 40% of electricity, and consuming less than 9 kilograms of standard coal per ton.

Process flowchart:

working principle:
1. If the moisture content of the dried material exceeds the specified value, the elimination method is to control the production capacity of the dryer and increase or decrease the supply of heat;
2. The reason why the rolling ring swings during the operation of the cylinder is that the concave joint of the rolling ring is not clamped on the side. The elimination method is to use a shim to keep the rolling ring and concave joint evenly clamped and properly clamped, to prevent accidents caused by over tightening;
3. The meshing clearance between the large gear and the small gear is damaged due to a Tugboat wear b Wheel wear c The elimination method for small gear wear is to turn or replace it according to the wear condition, or it can be installed on the opposite side or updated in pairs;
4. Whole body vibration is caused by a The connection between the towing device and the base is damaged. The solution is to correct and tighten the connection parts to ensure they are in the correct position;
