The utility model relates to the technical field of granulator, concretely is a kind of granulator's press scraper holder structure, the granulator's press scraper holder structure includes scraper holder and the press scraper holder assembly of being set to the one side of scraper holder, be provided with hobbing assembly between scraper holder and press scraper holder assembly, scraper holder includes base and two fixed in the upper end surface of base support, press scraper holder assembly includes backplate and the hydraulic ram of being set to the one end of backplate away from base, both ends of hydraulic ram are connected with lug plate, and hydraulic ram is connected with backplate and upper support table respectively by two lug plates, and upper support table is connected by two turnover hinges between backplate. The granulator's press scraper holder structure is contacted and connected with two supports respectively by two ejector pins, carries out pressure tight handling to support, guarantees that spline roller keeps stable state in working process, so that material can keep stable state and is delivered to scraper main body, guarantees the stability of long-term use.

The application discloses an intelligent fresh air control system for a blasting bead drying room, comprising an independent fresh air pipeline unit, a data acquisition unit, a control unit and an execution unit; the data acquisition unit is signal connected with the control unit, and is used for transmitting the collected temperature and humidity data to the control unit in real time. The application can realize stepless fine adjustment of fresh air volume, adapt to dynamic wet load of the blasting bead drying room, effectively inhibit environmental humidity fluctuation, significantly improve the stability of the blasting bead drying process and the consistency of the finished product quality; the system intelligently adjusts the fresh air introduction according to needs, greatly reduces the operation energy consumption of the dehumidification equipment, and saves production cost; through the control logic of multiple anti-frequent action, the mechanical wear of the valve is greatly reduced, and the service life of the equipment is prolonged; meanwhile, the rotating drum operation signal can be connected to make feedforward compensation, further improve the control precision, and has high popularization and application value.

This invention belongs to the field of gas detection technology, specifically relating to a device and method for detecting the decomposition products of perfluoroalkyl nitrile (PFAN) in insulating gases. The device includes a gas acquisition module, a pretreatment module, a multi-technology co-processing module, a detection chamber, and an intelligent data processing and control system. The gas acquisition module collects and concentrates gas samples through a sampling unit in the gas chamber and a low-temperature enrichment unit. The pretreatment module purifies the gas and converts complex components through a high-efficiency filter, a dryer, and a catalytic conversion unit. The multi-technology co-processing module uses a micro gas chromatography unit to separate the gas and an infrared spectroscopy unit for qualitative analysis. The gas-sensitive sensor array in the detection chamber enables multi-dimensional detection. The intelligent data processing and control system's storage module stores multiple databases, and the analysis module calls these databases to analyze data from multiple modules, achieving sampling, detection, and intelligent analysis of the decomposition products. This solves the problems of missed detections, lack of specificity, and low efficiency in existing detection methods.
