The explosion-proof scale is equipped with a carbon steel powder-coated or stainless steel frame, which can be widely applied in all aspects of industrial and agricultural production. The surface of the Electronic scale uses patterned steel plate / stainless steel plate, and the U-shaped frame at the bottom of the scale body is made by stamping steel plate / stainless steel plate. The design of the scale body has passed the 500,000 times fatigue loading test by a professional institution. The double-layer scale uses an inclined seat, and the lower end of the inclined seat is equipped with a groove, the top middle position of the groove is rotatably connected with a screw, the upper ring side of the screw is fixedly connected with a worm gear, the inner end of the worm gear meshes with the worm, the screw ring side is threadedly connected with an activity plate and the activity plate is located below the worm gear, the four corner positions of the activity plate at the lower end are all fixedly connected with universal wheels, the activity plate is slidably connected in the groove, the front and rear ends of the worm are rotatably connected with the inclined seat, using the worm gear and worm to make the screw rotate, thereby making the activity plate and the universal wheels move downward, causing the universal wheels to contact the ground and lifting the inclined seat, so that the inclined seat can be moved to the side of the protective frame for installation, which is convenient for the disassembly and assembly of the inclined seat, and reduces the installation time. It ensures that it is sturdy and durable during use. The double-layer frame design, the height from the scale platform to the ground is only 90mm (10t model is 130mm), it conforms to OIMLR60 and the protection level IP68 alloy steel / stainless steel welded sealed sensor, the high-precision junction box is mainly used to aggregate and transmit the signals of the four weighing sensors to the weighing instrument, the weighing sensors have slight differences in output impedance and sensitivity of the electronic scale, and when the load is located at different positions on the scale platform, an angle difference will be generated, the inside of the junction box is equipped with a precision potentiometer, precision discrete resistors, double hex rotary switches to adjust the angle difference, the coarse adjustment is x16, the fine adjustment is x1 (00 = minimum, FF = maximum, default 80), used to adjust the signal output of the four weighing sensors, thereby eliminating the angle difference and ensuring the weighing accuracy. 

The structure of the scale platform includes the upper scale plate and the lower scale plate. The upper edge of the lower scale plate is fixedly connected to the protective frame. Above the lower scale plate, the upper scale plate is set. Four devices are fixedly connected between the upper and lower scale plates. The upper scale plate is placed inside the protective frame and extends to the upper end of the protective frame. Auxiliary components are set at both ends of the protective frame, including inclined seats. The lower end of the inclined seat is provided with a groove, and the top middle position of the groove is rotatably connected with a screw. The upper part of the screw is fixedly connected with a worm gear, and the inner end of the worm gear meshes with the worm. The worm gear is fixedly connected with the outer side of the screw ring and is threaded to connect an activity plate, which is located below the worm gear and has four corner positions on the lower end fixedly connected with universal wheels. The activity plate is slidably connected in the groove. The front and rear ends of the U-shaped card blocks on both ends of the buffer scale platform are symmetrically fixedly connected and are located on the upper front and rear ends of the inclined seat. The upper front and rear ends of the inclined seat are fixedly connected with connecting shafts, which are inserted into the U-shaped card blocks. The screw ring of the buffer scale platform is threaded to connect a sleeve, which passes through the middle position of the activity plate and is fixedly connected with the activity plate. The front and rear ends of the groove are provided with sliding slots, and the middle positions of the front, rear, and left-right ends of the activity plate are fixedly connected with sliders, which are slidably connected in the sliding slots. The lower end of the screw is fixedly connected with a limit plate, which is located below the groove inside. The worm gear is passed through the inclined seat and fixedly connected with the turntable, which is rotatedly connected with a handle. The turntable is threaded with a tightening bolt, which passes through the turntable and is in contact with the front end of the inclined seat. The inclined end face of the inclined seat is provided with anti-slip patterns. 

The explosion-proof Weighing system for hazardous waste, based on advanced technologies such as IoT, big data, and AI intelligence, focuses on the full life cycle weighing control of hazardous waste from generation, storage, warehousing, outloading, and transfer. It builds an integrated solution of "automated collection, intelligent management, full-process traceability, and one-click compliance", completely solving the traditional management problems, providing efficient, precise, and safe weighing management new paradigms for waste-producing enterprises, disposal units, and regulatory authorities, and helping enterprises achieve the transformation from "passive compliance" to "active management". Through a unified monitoring interface, it automatically collects dynamic data from various monitoring environments and, based on these monitoring data, forms various reports (such as payment report, unpaid oil report, monthly and daily reports, etc.) and detailed tables, facilitating business statistics and queries. The powerful query function can be used to query user records, reports, etc. by various methods (such as ticket number, well position number, user code, product number, etc.), and on this basis, the system will also form a complete business information feedback and supervision control mechanism, providing strong support for enterprises to conduct scientific business management and decision-making. Automatic material issuance and centralized management functions. It can realize the automation of the issuance process, ensure control accuracy, and improve production efficiency; it can achieve various fault alarms, as well as static overflow protection, emergency stop protection; it can monitor the issuance status of each position in real time, with password recognition function; it accepts production data and production plan arrangements from superior management networks for production, generates reports and inventory management systems; it provides standard DDE and OPC interfaces, which can be conveniently communicated with DCS, ERP, etc. control and management systems. 

The explosion-proof electronic scale is suitable for the petroleum, chemical and blending industries. Based on computer technology, control technology, communication technology and graphic display technology (i.e. 4C technology), it connects the field control stations, control management stations, detection stations and operation management stations and engineer stations distributed in the industrial site (nearby) through the communication network to jointly complete the integrated control system for decentralized control and centralized operation and management. The electronic scale is an integrated intelligent weighing and control device specially developed for the hazardous waste and hazardous chemicals industries. It integrates intelligent weighing, automatic label printing, barcode scanning and recognition, inbound and outbound warehouse management, electronic forms, self-generation of ledgers, regulatory data connection, etc. It conforms to the standardized construction of "one code throughout" for hazardous waste, achieving "one code integration" in information management. It adopts the "five-in-one code" operation mode to realize digital and closed-loop management of the entire life cycle of hazardous waste from generation, collection, storage, transportation, disposal and other aspects. It fully realizes the automation of management in various business links of oil depots and chemical industries, and conducts automated monitoring of each user's work links, thereby assisting user managers in more efficient and accurate business processing.
