[0002] In the technological processes of industrial production, a large amount of media such as acids, alkalis, and poisons are used. At present, in most industrial fields, strongly corrosive and highly toxic chemicals are transported to the storage area by tank trucks and then conveyed to storage tanks for use through a conveying and unloading system. AHF tank trucks are now widely used by AHF manufacturers and accepted by AHF users because of their large filling capacity, convenient filling and transportation, and no trouble in steel cylinder management and plugging treatment.
[0003] At present, when the AHF tank truck unloading device is in use, most operations need to be completed manually on-site, including pressure testing for leakage detection, pressurization, discharging, stopping unloading, etc. Therefore, there are the following disadvantages: too many on-site operations may increase the situation of AHF burns to unloading personnel, resulting in a reduction in the safety of unloading personnel. Content of the Utility Model
[0004] The purpose of the utility model is to provide an AHF tank truck unloading device to solve the problem that too many on-site operations may increase the situation of AHF burns to unloading personnel, resulting in a reduction in the safety of unloading personnel.
[0005] To achieve the above-mentioned utility model purpose, the utility model adopts the following technical scheme: an AHF tank truck unloading device, including a loading arm, the loading arm is connected to the right end of the tank truck pipeline through a flange, a fixing hole is opened on the top surface of the tank truck pipeline, a pneumatic control valve is arranged on the tank truck pipeline, a first pressure sensor is fixed inside the fixing hole, and a flow meter is arranged on the tank truck pipeline.
[0006] Preferably, a leakage detector is detachably arranged above the tank truck pipeline.
[0007] Preferably, an installation hole is opened on the top surface of the loading arm, and a second pressure sensor is fixed inside the installation hole.
[0008] Preferably, a connection hole is opened on the top surface of the loading arm, and a temperature sensor is fixed inside the connection hole.

[0010] Preferably, sealing rings are fixedly arranged on the flanges of the loading arm and the tanker pipeline.
[0011] Compared with the prior art, an AHF tanker unloading device adopting the above technical solution has the following
[0012] beneficial effects:
[0013] 1. During use, through the pneumatic control valve, the first pressure sensor and the flowmeter, the unloading personnel only need to disassemble and assemble the flange connecting the loading arm and the tanker pipeline on-site once, and the rest of the actions can be remotely controlled by the DCS, optimizing the unloading operation procedure, ensuring the safety and reliability of the unloading process, not only improving the work efficiency, but also ensuring the personal safety of the unloading personnel and the safe storage of the materials;
[0014] 2. During use, through the leak detector, it is beneficial to detect the leakage at the connection between the loading arm and the tanker pipeline, and transmit the data to the DCS remote start system, which will quickly start the emergency response mechanism, including measures such as closing relevant valves. Through the second pressure sensor, it is beneficial to detect the pressure change inside the loading arm in real time, and upload the data to the DCS system for analysis and processing. When the pressure shows abnormal increase or decrease, the system will immediately issue an alarm to remind the operator to take corresponding measures. Through the temperature sensor, it is beneficial to detect the temperature fluctuation inside the loading arm in real time. Through the linkage with the DCS system, the operator can remotely monitor the temperature inside the loading arm and adjust the unloading speed or take other emergency measures according to the actual situation, improving the accuracy and real-time performance of the temperature monitoring inside the loading arm, and ensuring that the unloading operation is carried out within the safe temperature range;
[0015] 3. During use, when it is necessary to disassemble and assemble the leak detector, the unloading personnel only need to loosen the bolts to remove the mounting plate and the leak detector from the mounting block. Conversely, after aligning the mounting plate and the leak detector with the mounting block, tightening the bolts can complete the installation, simplifying the disassembly and assembly process of the leak detector and improving the work efficiency. The sealing ring effectively prevents the leakage of materials during the unloading process. Even under high pressure or high temperature conditions, the sealing ring can maintain a stable sealing effect, improving the sealing performance of the flange connection and ensuring the safety and reliability of the unloading operation.

Detailed implementation manners
[0021] The following will describe in detail the preferred embodiments of the present utility model with reference to the accompanying drawings.
[0022] As Figures 1 - 4 shown, an AHF tank truck unloading device includes a loading arm 1. The loading arm 1 is connected to the right end of the tank truck pipeline 2 through a flange. A fixed hole 3 is opened on the top surface of the tank truck pipeline 2. A pneumatic control valve 4 is provided on the tank truck pipeline 2. A first pressure sensor 5 is fixed inside the fixed hole 3. A flowmeter 6 is provided on the tank truck pipeline 2.
[0023] During use, the unloading personnel first dock the tank truck pipeline 2 with the loading arm 1 through a flange and fasten it with a flange connecting member to ensure a sealed connection between the two and prevent any form of leakage. Subsequently, the system is remotely started through DCS (Distributed Control System), and the valve is slowly opened with one-key control, marking the official start of the material unloading operation. The system automatically starts the pressurization program to pre-pressurize the pipeline to ensure that the pipeline pressure reaches the preset standard. Through the real-time monitoring of the first pressure sensor 5, the pipeline pressure change is accurately grasped, effectively testing the sealing performance of the pipeline and the connection part. During this process, the pneumatic control valve 4 plays a crucial role. It automatically adjusts the unloading flow rate according to the system instructions to ensure smooth and orderly material flow, avoiding material waste or pipeline damage caused by too fast or too slow flow rate. At the same time, the flowmeter 6 monitors the material flow rate online throughout the process, providing a reliable basis for the accurate calculation of the unloading volume. The entire unloading process does not require manual intervention and is controlled by an automated system, which not only improves work efficiency but also reduces the risk of human operation errors. The system monitors every detail during the unloading process in real time. Once potential safety hazards such as leakage and abnormal pressure are detected, the corresponding valve is automatically closed through the interlock logic. Through the pneumatic control valve 4, the first pressure sensor 5, and the flowmeter 6, the unloading personnel only need to perform the on-site operation of disassembling and assembling the flange connecting the loading arm 1 and the tank truck pipeline 2, and the rest of the actions can be remotely controlled by DCS, optimizing the unloading operation procedure and ensuring the safety and reliability of the unloading process, which not only improves work efficiency but also guarantees the personal safety of the unloading personnel and the safe storage of the material.
[0024] As Figures 1 - 3As shown, a leakage detector 7 is detachably arranged above the tank truck pipeline 2.
[0025] During use, the leakage detector 7 facilitates the detection of leakage at the connection between the loading arm 1 and the tank truck pipeline 2, and transmits the data to the DCS remote start system, which will quickly activate the emergency response mechanism, including measures such as closing relevant valves.
[0026] As Figure 1 、 Figure 2 and Figure 4 shown, an installation hole 8 is opened on the top surface of the loading arm 1, a second pressure sensor 9 is fixed inside the installation hole 8, a connection hole 10 is opened on the top surface of the loading arm 1, and a temperature sensor 11 is fixed inside the connection hole 10.
[0027] During use, the second pressure sensor 9 facilitates the real-time detection of pressure changes inside the loading arm 1 and uploads the data to the DCS system for analysis and processing. When the pressure shows abnormal increase or decrease, the system will immediately issue an alarm to remind the operator to take corresponding measures. The temperature sensor 11 facilitates the real-time detection of temperature fluctuations inside the loading arm 1. Through the linkage with the DCS system, the operator can remotely monitor the temperature inside the loading arm 1 and adjust the unloading speed or take other emergency measures according to the actual situation, improving the accuracy and real-time performance of temperature monitoring inside the loading arm 1 and ensuring that the unloading operation is carried out within the safe temperature range.
[0028] As Figures 1 - 4 shown, an installation block 12 is fixed on the top surface of the tank truck pipeline 2, an installation plate 13 is detachably arranged on the top surface of the installation block 12, the bottom surface of the installation plate 13 is fixedly connected to the bottom surface of the leakage detector 7, two threaded grooves 14 are opened on the top surface of the installation block 12, two threaded holes 15 are opened on the top surface of the installation plate 13, two bolts 16 are respectively threadedly connected inside the two threaded holes 15, and the threaded ends of the two bolts 16 are respectively threadedly connected to the inside of the two threaded grooves 14. Sealing rings 17 are fixed on the flanges of the loading arm 1 and the tank truck pipeline 2.
[0029] During use, when it is necessary to disassemble and assemble the leakage detector 7, the unloading personnel only need to loosen the bolts 16 to remove the installation plate 13 and the leakage detector 7 from the installation block 12. Conversely, after aligning the installation plate 13 and the leakage detector 7 with the installation block 12, tightening the bolts 16 can complete the installation, simplifying the disassembly and assembly process of the leakage detector 7 and improving the work efficiency. The sealing ring 17 effectively prevents the leakage of materials during the unloading process. Even under high pressure or high temperature conditions, the sealing ring 17 can maintain a stable sealing effect, improving the sealing performance of the flange connection and ensuring the safety and reliability of the unloading operation.
[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
