The automatic filling system for gas cylinders adopts automatic intelligent filling and intelligent management technology, which can effectively reduce the occurrence of personal injury accidents. During normal filling, the liquid chlorine filling system is equipped with an early warning system. When the value reaches the specified limit, it will issue an early warning. When the specified filling volume is reached, it will automatically cut off the filling valve through interlock. After the chlorine gas pipeline leaks, when the quality concentration of chlorine gas in the space exceeds 1mg/m³, the on-site toxic gas detector will detect the chlorine gas leakage and give an alarm. When the alarm value is reached, the system will interlock the opening of the chlorine gas evacuation valve and the closing of the liquid chlorine filling valve, and remotely start the accident caustic liquid spray system to spray caustic liquid. During this process, personnel do not need to operate at close range on site.

The cylinder scale system consists of a weighing instrument, a weighing sensor electrically connected to the scale platform, a filling drive mechanism, a filling platform, and a filling mechanism. The cylinder is placed on the filling platform, which is suitable for positioning and placing the cylinder, and the weighing sensor is adapted to collect the weight data of the cylinder in real time and send it to the weighing instrument. The weighing instrument controls the filling drive mechanism to drive the filling mechanism to fill the cylinder placed on the filling platform. When the weight data collected by the weighing sensor reaches the preset value, the function of uniform filling can be achieved by collecting the weight data of the cylinder.

Explosion-proof weighbridge introduces RFID technology into warehouse management, and automatically collects the data of each operation link, such as warehouse arrival inspection, warehousing, warehousing, allocation, warehouse transfer, inventory counting, etc., to ensure the speed and accuracy of data input in each link of warehouse management, and to ensure that enterprises can accurately grasp the real data of inventory in time for warehouse weighing and track incoming and outgoing goods.

The explosion-proof dynamic load scale uses four weighing sensors to support the platform. When a vehicle moves dynamically over the platform, the scale platform transmits the vehicle weight to the weighing sensors. As the vehicle passes over the scale platform, the weighing sensors convert the pressure signal into an analog electrical signal, which is then sent to the analog input port of the A/D converter through an amplifier. The converted digital quantity is processed as a sampling value and sent as the dynamic scale weight to the computer through the communication interface. It is printed out or stored for further processing via the printer or storage device.

The structure of the hazardous waste electronic weighing platform consists of an upper platform, a supporting platform (i.e. the lower platform), four sets of levers, counterweight blocks, four weighing sensors, a wiring box and a digital instrument. The upper platform is supported by four floating columns below, and each of the four floating columns presses against one end of the four sets of levers. The floating columns are composed of rubber body ball-head columns and ball-head tops.

The cylinder scale adopts automatic height compensation, automatic zeroing, automatic zero-point tracking; manual/automatic switching; real-time monitoring of filling conditions; the software has safe operation features; it also has a database for filled bottles, which manages whether the filled bottles are qualified or registered based on the database, and stores the measurement results after the filling process. The human-machine interface is a three-dimensional dynamic simulation graphic, showing the real-time weight during filling; an alarm prompt is given upon the completion of filling, and an effective information is automatically formed and saved; the filling database information can be saved, backed up, restored, queried, printed, and statistically processed. The software implements hierarchical management; a data link function is reserved, which can link the data of the automatic control system according to the corresponding format of the safety supervision bureau database.

The explosion-proof electronic scale directly transmits the weight signal from the scale platform to the weighing sensor. In the electronic scale, in order to enhance the shock resistance of the scale and protect the weighing sensor, an additional lower scale platform, namely the secondary scale platform, is added to the structure. The secondary scale platform is a frame structure made of steel sections. Four sets of buffer devices composed of springs are installed between the main and secondary scale platforms. The weight signal of the main scale platform needs to be buffered by the buffer device before being transmitted to the secondary scale platform and the weighing sensor. This significantly reduces the destructive effect of shock forces on the weighing sensor and the scale platform.

The material tank floor scale acts on each weighing module through the tank car track, forming A multi-point force-bearing weighing track. After the tank car passes through the measurement area of the floor scale, the weighing module converts the vehicle weight into a voltage signal according to a strict linear relationship. After being amplified and filtered by a high-performance amplifier in the signal conditioning circuit, and then converted by A/D, The embedded data acquisition and processing system accomplishes digital filtering, data acquisition, tanker discrimination, calculation of weight saving and speed, and performs high-precision correction and compensation based on the vehicle speed.

TheExplosion-proof feeding scale uses a frequency converter to achieve two-speed speed control for feeding, thereby realizing the functions of fast, slow and point feeding control for four types of materials, ensuring the accuracy and speed of variable-frequency feeding. After starting the pre-set metering feeding program, the weight of the hopper conveyor belt is measured and stored, and then various ingredients are successively controlled to enter the hopper conveyor. Among them, dry materials are metered into the hopper conveyor by a vibrating disc, powder materials are metered into the hopper conveyor by a screw feeder, liquid materials are metered into the hopper conveyor by a hydraulic valve, and pasty materials are metered into the hopper conveyor by a pump.
