However, this method is a method of statically judging the moisture content, and the error is relatively large. The moisture content of the treated sludge obtained is often far from the target moisture content. Not only is the calculation process complicated, there are many control factors, and the drying effect is not satisfactory.
[0004] 2. The moisture content of the sludge in the tank can be judged in real time by installing an instrument to detect the moisture content in the drying tank. The working principle of the drying tank is to realize the drying of the sludge by heating and stirring, which makes the equipment set in the tank The moisture content detection instrument is easily damaged, and the instrument that can detect the moisture content of the sludge online in real time is expensive, which makes the method expensive and the loss is serious

Abstract
The invention relates to a drying and granulation control method and a vertical drying and granulation integrated equipment using the method. The method uses a motor to control the rotation of the cutter shaft assembly to stir or cut the material to be dried, and the output current of the motor is used to control the drying and granulation. Determine whether the moisture content of the material to be dried meets the requirements. Its equipment includes a vertical tank body and a cutter shaft assembly arranged in the vertical tank body. The cutter shaft assembly is equipped with intermittent spiral ribbon-shaped blades, and a cutting edge is provided at the front end of each blade. Each blade is connected to the cutter shaft assembly through a connecting rod; it also includes a central control module and a motor connected to it to drive the rotation of the cutter shaft assembly to stir, transport or cut the material to be dried in the tank, and to collect Current sensor for motor current. The invention only needs to detect the motor current to judge whether the moisture content of the material to be dried in the tank meets the requirement, the control method is simple, the cost is low, and it has strong practicability and economy.
Description
technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a drying and granulation control method and a vertical drying and granulation integrated device using the method. Background technique [0002] With the increase of urban population, the need for urgent treatment of urban sewage and sludge is increasing, and a variety of sludge drying and sludge drying equipment have also appeared. In the prior art, when the sludge is dried, its moisture content is an important indicator for determining whether the drying is completed. The material in the tank is dried), and the moisture content detection instrument cannot be directly installed in the tank, resulting in the inability to estimate the moisture content of the sludge in the tank. Existing practices include the following two: [0003] 1. According to the set target moisture content, the drying time corresponding to the moisture content can be calculated by comprehensive fac...
