Analysis of Deviation Correction Technology of Vacuum Belt Dryer

The strip rectification system of the vacuum belt dryer has been the problem that most domestic manufacturers have not solved it yet, and users complain more. Some domestic manufacturers are often just imitating rather than trying to develop because of the lack of technical strength, thinking that the configuration of imported equipment can achieve the purpose, but in fact it is not so easy. In essence, due to its limited manufacturing capacity, foreign products have absolute guarantees in materials, machining, heat treatment technology, manufacturing precision, etc., and the rigor of installation procedures is also temporarily unavailable for us. So the same configuration can make the most of it. As a domestically produced device, we should first clearly recognize the existence of this gap, and then use the existing conditions to achieve technological breakthroughs through independent development to achieve the same purpose.

1) The strip rectification form is mainly divided into two types: guide strip mechanical forcing correction and fully automatic online rectification. Both forms need to be selected according to the drying characteristics of the material and the material of the conveyor belt. The mechanical forcing correction method of the guide bar seems to be relatively simple, but it is not easy to ensure that the design is reasonable. As for the automatic online correction, the technical difficulty is even higher. There are many factors to be considered in the design of the correction system. The first is the adjustment of the tension of the belt (main correction system), which is the main component of the correction system. Because it is closely related to the transmission system, it is designed. The selection of the cylinder, the use of the coupling, the distribution of the compressed air, the manufacturing accuracy of the coupling, and the configuration of various bearings must be strictly controlled. In the design of the correction system, the selection of the sensor is very critical. The configuration of this accessory in the domestic vacuum belt dryer basically adopts the imported fiber sensor or the magnetic displacement digital sensor. Both sensors have their own characteristics. The former is relatively It is relatively simple, but the correction parameters are less accurate and are susceptible to evaporation conditions during on-site drying. The latter has extremely high precision. The permanent magnet ring continuously detects the cumulative displacement information at 1/2000 points in the range of ±1cm, and is not affected by the vacuum, temperature difference and the erratic environment of dry and wet conditions. Accurate and stable belt offset values ​​provide a reliable guarantee for the implementation of the corrective system, but are expensive and extremely careful during installation, otherwise they are easily damaged.

2) There is another auxiliary correcting device in the correcting system. It must also be considered. Most manufacturers in China have not paid enough attention to this device. They always think that the main correcting system mentioned above can achieve the goal. And the final result of zui can be imagined. Auxiliary rectification includes two parts: tracking detection and buffer rectification. The function of tracking detection is mainly to effectively control the belt during operation, and provide controllable range for information acquisition of sensors in the main rectification system, especially using guide strips. Mechanical forced rectification dryers, intermediate transitions and tracking adjustments are very important. The buffer correction is a balance adjustment of the friction between the drive shaft and the belt after the main correction is completed, which can help the quick reset after each correction and the large effective contact surface between the belt and the transmission shaft. .

3) The processing and assembly precision of the components in the correcting system are very high. Especially the moving parts need to be precisely processed according to the standard of mechanical processing. In the assembly process, the corresponding fixtures need to be configured, and try to avoid Excellent precision-free manufacturing methods such as welding, so excellent manufacturers are equipped with professional engineering and technical personnel in this field. However, some manufacturers have placed their hopes for correcting deviations on self-control because of the limited design capability of machining and fixtures. They think that the mechanical precision can not be compensated by self-control. In fact, this is the idea of ​​completely inverting the concept of mechanical products. Because self-control is only a system for mechanical action, if a set of sports machinery does not have high-precision parts as the basic guarantee, even the advanced automatic control system will not help.
