1DY-1600Overview of type sludge belt dryer

The sludge belt dryer is a product independently designed and developed by our factory, specialized in drying various materials in the sludge industry, successfully replacing the previous oven drying process. The machine has a wide range of applications, and the quality indicators of the dried products are high, which greatly saves manpower.The automation and continuous use of materials and energy for drying have taken a new step forward, which is a novel approach.Efficient.Energy saving drying machine.

IIDY-1600Working principle of type sludge belt dryer

The material is extruded into strips by a spiral extrusion mechanism and evenly fed onto the mesh belt of the belt dryer. Mesh belt adopts16~20The purpose of the stainless steel mesh is to be driven by a variable frequency rotating device to move the mesh belt at a constant speed inside the dryer box, and the material is circulated through the upper and lower air streams. The airflow circulates through the fan and heater, and the material is heat exchanged and dried by the hot air distribution plate. During the circulation process, gases with high humidity content in the air are discharged through the dehumidification port, regulating valve, and dehumidification fan. The other part of the gas is circulated and heated by a circulating fan to achieve full utilization of heat energy. A small amount leaks to the bottom for material separation, and is discharged from the cleaning system to the spiral discharge to ensure continuous operation of the dryer.

When drying pigments, a two-stage belt dryer is generally used in series, which is divided into a feeding section and a discharging section. Due to the high moisture content and poor breathability of the material in the feeding section, a thin layer of material is used, resulting in fast operating speed and high drying temperature. According to the properties of the material, the temperature is generally around120 Due to the fact that most of the moisture in the material is removed in the feeding section, the moisture content of the material entering the discharging section is relatively low, and the material is breathable. Moreover, the moisture content of the material is mainly due to the need for a certain drying time for internal moisture. Therefore, the mesh belt should be placed in a slower position and the material layer should be thickened. According to the properties of the material, the drying temperature cannot exceed the temperature that the material can withstand. The temperature inside the drying cabinet is measured by temperature measuring points and controlled by solenoid valves to regulate the flow of steam, thereby achieving the goal of temperature control. Through two-stage drying, the performance of the belt dryer was better utilized. After drying, the material has uniform moisture content, color, strength, luster, etc., which greatly improves the quality of products dried by other drying equipment
