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：

干化機(jī)主要由夾套，單軸轉(zhuǎn)子和傳動(dòng)裝置組成。固廢通過(guò)夾套，空心軸和軸上焊接的空心盤(pán)片的熱傳到被間接加熱干化。盤(pán)片對(duì)固廢沒(méi)有切割，而是通過(guò)盤(pán)片邊緣的推進(jìn)攪拌器的作用，對(duì)固廢進(jìn)行攪拌，不斷更新干化面，從而實(shí)現(xiàn)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.

應(yīng)用：

槳葉干化機(jī)已成功地用于食品、化工、石化、染料、工業(yè)固廢等領(lǐng)域。設(shè)備傳熱、冷卻、攪拌的特性使之可以完成以下單元操作:燃燒(低溫)、冷卻、干燥(溶劑回收)、加熱(融化)、反應(yīng)和滅菌。攪拌槳葉同時(shí)又是傳熱面，使單位有效容積內(nèi)傳熱面積增大，縮短了處理時(shí)間。楔型槳葉傳熱面又具有自清潔功能。壓縮-膨脹攪拌功能使物料混和均勻。物料沿軸向成“活塞流”運(yùn)動(dòng)，在軸向區(qū)間內(nèi)，物料的溫度、濕度、混合度梯度很小。用導(dǎo)熱油做熱介質(zhì)，槳葉干化機(jī)可完成低溫燃燒工作。如:二水硫酸鈣(Ca,SO.·2HO)燃燒轉(zhuǎn)化為半水硫酸鈣(Ca,SO，·1/2HO)，(NaHCO,)經(jīng)燃燒轉(zhuǎn)化為純堿(Na,CO,)等。通入冷卻介質(zhì)，如水、冷卻鹽水等即可用來(lái)冷卻。如:使用于純堿行業(yè)的槳葉式?jīng)鰤A機(jī)，取代老式的空氣冷卻涼堿機(jī)，節(jié)省了能源及尾氣處理設(shè)備，降低了操作費(fèi)用。干燥，設(shè)備最主要的功能，不使用熱空氣，使溶劑回收、能源消耗、環(huán)境控制處于易處理的理想狀態(tài)。對(duì)需回收溶劑、易燃易氧化熱敏性物料尤為適應(yīng)。已廣泛用于精細(xì)化工、石化、染料行業(yè)。軸向區(qū)間內(nèi)，溫度、濕度、混合度的均勻性，使得設(shè)備可用來(lái)加熱或融化，或進(jìn)行一些固體物料反應(yīng)。在復(fù)合肥及變性粉行業(yè)均已成功使用。槳葉干化機(jī)可用來(lái)對(duì)食物和面粉進(jìn)行滅菌處理。單位有效容積內(nèi)大的加熱面積，很快就將物料加熱到滅菌溫度，避免了長(zhǎng)時(shí)間加熱而改變物料品質(zhì)。

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.
