摘要:

译文:带式干燥机是这样一种装置,其用于连续式干燥和冷却的粒料,糊剂,成型体化合物和面板使用空气,惰性气体,或烟气。

工作原理

带式干燥机/皮带冷却器是一个特别温和的热处理产品设计的设备。湿产物是连续和均匀地施加到穿孔带通过一个进料室。皮带上,主要在水平位置,进行干燥区域被划分成几个部分的产品通过。在这些细胞中的干燥气体流过或以上的湿产物并干燥。每个单元格都可以配备的通风风扇和热交换器。这种模块化设计允许在不同的部分中的干燥和冷却的温度可以单独控制。因此,可以单独地控制每个干燥器单元,并在每个单元格中的干燥/冷却的空气流,可以改变。此外,传送带的速度可以改变,给出了一个附加的参数设置干燥时间。该细胞可被加热或冷却,直接或间接地,可以使用所有的加热介质,如油,蒸汽,热水或热气体。 设计特点

带式干燥机/皮带冷却器设计的模块化系统。每个带式干燥机由进料头,皮带输送机,放电结束。不同类型的干衣机是可能的构造,例如

单带式干燥机 多级干燥器 多级干燥器 多带式干燥机

通风选项

气体流量模式一般有两种方式。干燥空气可以流动,根据治疗过程中,无论是通过或以上的产品。 作为输送带选项,

进料变化

造粒厂 - 滤饼或无定形和浆糊状产品 回转皮带输送机 - 敏感和自由流动的产品 分布螺旋 “旋转臂输送设备 - 稳定的产品 板喂养

典型应用

带式干燥机主要用于以下行业: 化学工业 医药行业 食品和饲料的东西行业 非金属矿物制造业 塑料行业 木材工业 陶瓷工业

产品举例

胶合板,木纤维绝热板,涂料,成型材料,合成橡胶,超吸收性聚合物,硬脂酸盐,催化剂,焦炭,水果,蔬菜,谷类食品。

原文:Belt dryer A belt dryer is an apparatus which is used for continuous drying and cooling of pellets, pastes, moulded compounds and panels using air, inert gas, or flue gas. Contents

Working principle

A Belt dryer / Belt cooler is a device designed for the particularly gentle thermal treatment of product. The wet product is continuously and evenly applied through an infeed chamber onto a perforated belt. The belt, predominantly in horizontal position, carries the product through the drying area which is divided into several sections. In these cells drying gas flows through or over the wet product and dries it. Each cell can be equipped with a ventilating fan and a heat exchanger. This modular design allows the drying and cooling temperatures to be controlled separately in the different sections. Thus, each dryer cell can be individually controlled and the drying / cooling air flow can be varied in each cell. In addition, the speed of the conveyor belt can be varied what gives an additional parameter for setting of drying time. The cells can be heated or cooled directly or indirectly, and all heating media, such as oil, steam, hot water or hot gas can be used. Design features

Belt dryers / Belt coolers are designed in modular system. Each belt dryer consists of infeed head, conveyor belt and discharge end. Different kinds of dryers are possible to construct, e.g.

Single-belt dryer Multi-stage dryer Multi-level dryer Multi-belt dryer

Ventilation options

In general there are two ways of gas flow pattern. The drying air can flow, according to the treatment process, either through or over the product. [1] Exemplary conveyor options

Chain-guided wire mesh conveyor Chain-guided hinge slat conveyor Chain-guided steel plate conveyor Chainless wire mesh conveyor

Feeding variations

Granulating mill – filter cake or amorphous and paste-like products respectively Slewing belt conveyor – sensitive and free flowing products Distribution spiral Rotatable arm feeding device – stable products Plates feeding

Typical applications

Belt dryers are predominantly used in the following industries:

Chemical Industry Pharmaceutical industry Food and feeding-stuff industry Non-metallic minerals industry Plastics industry Wood industry Ceramics Industry

Product examples

Veneers, wood fiber insulating boards, paints, molding materials, synthetic rubber, superabsorbent polymer, stearate, catalysts, coke, fruits, vegetables, cereals.
