On the basis of absorbing advanced technology at home and abroad, our company has improved and optimized the wedge-shaped hollow blade dryer, which can indirectly heat or cool paste, granular, powdery and slury materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction and low-temperature calcination. The special wedge-shaped stiring heat transfer blade in the equipment has high heat transfer efficiency and self-cleaning function of heat transfer surface. Wedge-shaped hollow blades are densely aranged on the holow shat, and the heat medium passes through the blades through the hollow axial flow. The heat transfer area per unit effective volume is very large, and the temperature of the heat medium ranges from -40 to 320'C, which can be steam or liquid, such as hot water and heat transfer oil. Indirect conduction heating, without carrying air to take away heat, heat is used to heat materials. The heat loss is only the heat dissipation to the environment through the insulation laver of the device body. The heat transter surtace of wedae blade has sel-cleaning funcion. The relative motion beween the material particles ano the wedoe-shaped surace produces a scrubbing effect which can wash of the attached materials on the wedae-shaped surface and keep a clean heat transter surface during operation. The shell of the blade drver is W-shaped. and two to four holow stirino shafts are generally aranged in the shel. The shell has a sealed end cover and an upper cover to prevent material dust from leaking out and colect material solvent vapor. A bale is arranged at the discharge port to ensure the height of the material level, so that the heat transfer surface is covered by the materia and fully plavs its role. The heat medium flows through the shel iacket and the holow stiring shaft through the rotarv ioint and the holow stiring shaft has diterent interna structures accoroina to the te ot heat medum to ensure the best heat transfer effect.

原理：

干化机主要由夹套，单轴转子和传动装置组成。固废通过夹套，空心轴和轴上焊接的空心盘片的热传到被间接加热干化。盘片对固废没有切割，而是通过盘片边缘的推进搅拌器的作用，对固废进行搅拌，不断更新干化面，从而实现干化的目的。
The drving machine is mainly composed of iacket, sinale shaft rotor and transmission device. The solid waste passes through the jacket holow shaft and heat transfer from the hollow disc welded to the shaf to be indirectly heated and dried. The disc does not cut solid waste but mixes solid waste by pushing the agitator on the edge of the disc, and constantly updates the drying surface, so as to achieve the purpose of drying.

应用：

桨叶干化机已成功地用于食品、化工、石化、染料、工业固废等领域。设备传热、冷却、搅拌的特性使之可以完成以下单元操作:燃烧(低温)、冷却、干燥(溶剂回收)、加热(融化)、反应和灭菌。搅拌桨叶同时又是传热面，使单位有效容积内传热面积增大，缩短了处理时间。楔型桨叶传热面又具有自清洁功能。压缩-膨胀搅拌功能使物料混和均匀。物料沿轴向成“活塞流”运动，在轴向区间内，物料的温度、湿度、混合度梯度很小。用导热油做热介质，桨叶干化机可完成低温燃烧工作。如:二水硫酸钙(Ca,SO.·2HO)燃烧转化为半水硫酸钙(Ca,SO，·1/2HO)，(NaHCO,)经燃烧转化为纯碱(Na,CO,)等。通入冷却介质，如水、冷却盐水等即可用来冷却。如:使用于纯碱行业的桨叶式凉碱机，取代老式的空气冷却凉碱机，节省了能源及尾气处理设备，降低了操作费用。干燥，设备最主要的功能，不使用热空气，使溶剂回收、能源消耗、环境控制处于易处理的理想状态。对需回收溶剂、易燃易氧化热敏性物料尤为适应。已广泛用于精细化工、石化、染料行业。轴向区间内，温度、湿度、混合度的均匀性，使得设备可用来加热或融化，或进行一些固体物料反应。在复合肥及变性粉行业均已成功使用。桨叶干化机可用来对食物和面粉进行灭菌处理。单位有效容积内大的加热面积，很快就将物料加热到灭菌温度，避免了长时间加热而改变物料品质。

Blade dryer has been successfully used in food, chemical.petrochemical，dye， industrial solid waste and other fields. Thecharacteristics of heat ransfer, cooling and stirring make it possible tocomplete the following unit operations: combustion (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 in the unit effective volume and shortens the treatment time. The heat transfer surface of wedge blade has self cleaning function. The compression-expansion stirring function makes the materials mix evenly. The material moves in a "plug flow" along the axial direction. In the axial range, the gradient of temperature, humidity and mixing degree of the material is very small! Using heat transfer oil as heat medium, the blade dryer can complete low temperature combustion. For example, calcium sulfate dihydrate (Ca,SO2H,O) is converted into calcium sulfate hemihydrate (Ca,SO·1/2H,O) by combustion, and sodium bicarbonate (NaHCO) is converted into soda ash (Na,CO,) by combustion. Cooling medium. such as water and cooling brine, can be used for cooling. For example, the paddle-type alkali cooler used in soda industry replaces the old air-cooled alkali cooler, saving energy and tail gas treatment equipment and reducing operating costs. Drying, the main function of the equipment, does not use hot air, so that solvent recovery, energy consumption and environmental control are in an ideal state of easy treatment. It is especially suitable for flammable and easily oxidized heat-sensitive materials that need to recover solvents. It has been widely used in fine chemical industry, petrochemical industry and dye industry. In the axial range, the uniformity of temperature, humidity and mixing degree makes the equipment can be used for heating or melting, or for some solid material reactions. lt has been successfully used in compound fertilizer and modified powder industries. The paddle dryer can be used to sterilize food and flour. The large heating area per unit effective volume can quickly heat the material to the sterilization temperature, thus avoiding changing the quality of the material due to long-term heating.
