Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for fire extinguishing agent production and batching, specifically to a high-precision fire extinguishing agent loss-in-weight weighing and batching system. Background Technology

[0002] In existing technologies, the production of water-based fire extinguishing agents generally requires adding each component to a reaction vessel and mixing it with water to prepare an aqueous solution. However, when it comes to the batching of solid components such as urea, ammonium phosphate, ammonium bicarbonate, and trisodium phosphate, a batching system is required to quantitatively batch the solid components. Among them, the loss-in-weight weighing batching system is a commonly used quantitative batching system.

[0003] The loss-in-weight weighing and batching system is an intelligent system integrating sensing, computing, and control. Its core components include load cells, a weighing hopper, a screw feeder, and high / low level switches. During operation, the load cells collect real-time weight data from the hopper, and the PLC control system precisely adjusts the screw feeder's speed, achieving millisecond-level response in material flow. When the hopper weight drops to the preset lower limit, the loading solenoid valve immediately starts replenishing material; when the upper limit is reached, it automatically closes, switching to a precise loss-in-weight control mode. This "loss-in-weight metering" determines the flow rate by calculating the weight loss of material per unit time, with an accuracy of less than 0.1%, far superior to traditional volumetric metering.

[0004] However, in practical use, existing loss-in-weight weighing and batching systems usually require on-site visits to check and schedule weighing data. This necessitates repeated movement and relocation to different batching system locations to complete the scheduling work, resulting in low efficiency. Furthermore, adjusting batching parameters also requires on-site visits, which undoubtedly increases the workload of maintenance and presents significant inconvenience in use. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision loss-of-weight weighing and dispensing system for extinguishing agents in order to solve the above problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a high-precision fire extinguishing agent loss-of-weight weighing and batching system, including a weighing hopper device, a transition hopper device, and a screw feeder device. The transition hopper device and the screw feeder device are respectively connected to the upper and lower positions of the weighing hopper device, so as to replenish the weighing hopper device with the transition hopper device and replenish the raw materials to the feeding position with the screw feeder device.

[0008] The weighing hopper, the transition hopper, and the screw feeder are respectively connected to a weighing detection module, a rapid feeding module, and a frequency conversion adjustment module. The weighing detection module, the rapid feeding module, and the frequency conversion adjustment module are all connected to a display instrument terminal to realize loss-in-weight weighing and batching operations with the help of the display instrument terminal, the weighing detection module, the rapid feeding module, and the frequency conversion adjustment module.

[0009] The display instrument terminal is connected to a dual-mode communication terminal, which is connected to a field control station device and a cloud server device respectively. At the same time, the field control station device and the cloud server device are connected to a wired landline dispatch terminal and a remote handheld dispatch terminal respectively, so as to use the wired landline dispatch terminal and the remote handheld dispatch terminal to schedule and control the data of the display instrument terminal at the monitoring station and at other locations.

[0010] Preferably, the weighing detection module is a weighing sensor, and the weighing hopper equipment is equipped with an arch-breaking motor.

[0015] Preferably, the cloud server device further includes a remote communication module, and the cloud server device is remotely and wirelessly connected to the handheld dispatch terminal through the remote communication module.

[0016] Preferably, the cloud server device includes a weighing data backup module capable of real-time cloud storage and backup of weighing data.

[0017] Preferably, the cloud server device further includes an identity verification module capable of verifying identity and permissions during the scheduling process of the remote handheld dispatch terminal.

[0018] Preferably, the wired landline dispatch terminal is a computer with a display, and the remote handheld dispatch terminal is a smartphone.

[0019] The aforementioned high-precision loss-in-weight weighing and batching system for extinguishing agents, specifically for the weighing and batching of extinguishing agents, achieves automatic replenishment of the weighing hopper by controlling the feeding of the transition hopper via the rapid feeding module. Simultaneously, the weighing detection module measures the weight of the weighing hopper, enabling real-time acquisition of the discharge volume. Furthermore, the frequency converter regulates the discharge of the screw feeder, stopping the discharge promptly once the required volume is reached. This system enables loss-in-weight weighing and batching of extinguishing agent raw materials, ensuring a reliable and easily implemented weighing and batching process that guarantees accurate quantitative batching of extinguishing agent raw materials. Since the display instrument terminal is connected to the field control station and the cloud server via a dual-mode communication terminal, and the field control station and the cloud server are connected to a wired landline dispatch terminal and a remote handheld dispatch terminal respectively, the system leverages the wired communication... The landline dispatch terminal and the remote handheld dispatch terminal can respectively dispatch and control the data of the display instrument terminal from the monitoring station and other locations, thereby realizing remote dispatch and control of symmetrical batching operations and emergency dispatch and control. This replaces the operation method that requires on-site dispatch and control, improves the efficiency of emergency dispatch and control, and allows staff to complete batching and processing work smoothly in various locations. Furthermore, thanks to the weighing data backup module of the cloud server device, weighing data can be stored and backed up, which helps to ensure reliable storage of weighing data and prevent accidental loss. It is convenient to regularly check and calibrate during the production process, ensuring that the production process is traceable. At the same time, the identity and permission verification module of the cloud server device can verify the identity and permission of the dispatching process of the remote handheld dispatch terminal, preventing the weighing data from being accessed, leaked, or tampered with, which helps to ensure the security of weighing data and further improves the reliability and stability of the weighing and batching process of fire extinguishing agent.

[0020] The beneficial effects are as follows: 1. This utility model can automatically replenish the weighing hopper by controlling the feeding of the transition hopper through the rapid feeding module. At the same time, the weighing detection module can weigh and measure the weighing hopper to obtain the discharge amount in real time. Moreover, the discharge control of the screw feeder by the frequency conversion adjustment module can stop the discharge in time after the discharge amount is reached. This enables the loss-in-weight weighing and batching operation of the fire extinguishing agent raw materials. The weighing and batching process is reliable and easy to implement, ensuring accurate quantitative batching of the fire extinguishing agent raw materials.

Terminal 10 can schedule and control the data of display instrument terminal 7 from both the monitoring station and locations outside the monitoring station, thereby realizing remote scheduling and control of symmetrical batching operations and emergency scheduling and control. This replaces the operation method that requires on-site scheduling and control, improving the efficiency of emergency scheduling and control. At the same time, it allows staff to smoothly complete batching and handling work in various locations. Furthermore, thanks to the weighing data backup module 901 of the cloud server device 9, weighing data can be stored and backed up, which helps to ensure reliable storage of weighing data and prevent accidental loss. It also facilitates regular review and calibration during the production process, ensuring that the production process is traceable.
