Transfer of second-hand stainless steel hollow paddle dryer

The company handles used 60 square stainless steel hollow paddle dryer, Lanzhou Chemical Machinery Plant equipment manufacturing, 90% of new equipment in urgent need of treatment. 13,792,347,422 works edit efforts drying paddle dryer is a kind of conduction-based horizontal mixing dryer. W-shaped casing main structure is built with a jacket has a pair of hollow low speed rotation of the hollow shaft, the shaft welding a number of stirring blades, jacket and hollow mixing blades, are through to the heat carrier within two heating surface while heating the material. Heat carrier is usually from the dryer into the middle, was stirred by the state of the surface of the material layer, the other side is discharged. Hollow shaft lined with dense wedge hollow blades, the heat medium through the hollow axial warp blades. The effective heat transfer area per unit volume is large, the heat medium temperature from -40 ~ 320 ° C, can be steam, it may also be liquid type: such as water, oil and the like. Indirect conduction heating, no air carrying away heat, the heat was used to heat the material, thermal insulation layer of the heat loss is only through the body to the environment. Wedge-shaped blade heat transfer surface with self-cleaning function, material particles relative movement of the wedge surfaces produce wash effect, it can wash away the surface of the wedge-shaped attachment material, so that movement has maintained a clean heat transfer surfaces. 2 Main features editor 1, the material residence time is adjustable, can handle high water content materials, low moisture content materials can be obtained; 2, a typical conduction drying methods, energy, conductivity, high thermal efficiency; 3, because all the heat required by the hollow blades and a jacket supply, in order to reduce exhaust humidity, add a few small amount of hot air, dust entrainment low exhaust easy to handle without dust and other auxiliary equipment. 4, the blade has a self-cleaning ability. Counter-rotating blades, vanes stir again two slopes, compression, relaxation and promote the material, so that the page has a unique byte capacity, the heating surface continue to receive updates, but also the paddle dryer heat transfer coefficient higher than any other conductive drying methods. 3 advantage Editor Compact: Dryer primary heat transfer member is shovel-shaped blades, these blades are intensive, at predetermined intervals staggered in fixed rotational axis, and therefore relatively high heat per unit volume. For this reason, the structure of this device is very compact, small footprint. High heat transfer efficiency: good due to the continuous mixing of raw materials, due to the relative rotation of the spade blade and the inclined surface of the blade and the body is heated, cooled, and the product to ensure that all surfaces in contact can uniformly heat transfer. Self-cleaning properties: the movement is due to the relative rotation of the blades, they play near the inner surface of the continuous self-cleaning effect. Bonded to each other, and the product deposited on the blades can be cleared down and re-enter the production process. Control is simple: the drying process and residence time can simply check, control and adjustment. They can be individually set and adjusted according to the physical properties of the dried product is, the number of axes or paddle, speed, temperature and heat transfer bodies to set and adjust the drying time. Less dust and odor: Due to the drying process used in the gas flow is small, so dust and odors can be generated is small. Therefore, instead of supporting the use of cleaner or deodorizers also have little or no need to use. Suitable for humid dry product: the use of a paddle drying elements and continuous mixing, capable of great viscosity and high humidity drying materials. Its structure is designed to avoid overheating of the product due to product accumulates and accumulates brought dead at or spoilage. Almost no wear and material loss: blade speed is very low, only 10 to 40 revolutions per minute, which effectively avoid abrasion and erosion caused by the rapid wear of machine equipment. Further, it will reduce the risk of rupture of the metallic material to a minimum extent. 4 Applicable materials editor 1, Inorganic Chemicals: calcium nitrate, calcium sulfate, paper, calcium carbonate, magnesium hydroxide, carbon black, iron black, iron red, soda, soda ash; 2, organic chemical industry: dyes, industrial plastics , polystyrene, polypropylene, high density polyethylene, polypropylene, etc.; 3, smelting industry: nickel concentrate powder, sulfur concentrate powder, tar, phenol removal; 4, food and medical industry: starch, pharmaceuticals, salt protein; 5, other: sludge, waste, chicken feed, distillers grains and the like;
