[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] refer to Figure 1An automated liquid chlorine filling system includes a weighing instrument 1, a receiving trolley 2, a first filling pipe 3, a filling shut-off valve 4, and a evacuation assembly 5. The receiving trolley 2 is mounted on the weighing instrument 1 and is used to receive liquid chlorine. The weighing instrument 1 can be a weighbridge to accurately measure the weight of the receiving trolley 2. The weighing instrument 1 can measure the overall weight of the receiving trolley 2. By comparing the weight of the receiving trolley 2 before and after filling, the filling weight of liquid chlorine in the receiving trolley 2 can be determined. One end of the first filling pipe 3 is detachably connected to the receiving trolley 2. It can be connected during filling to enable the receiving trolley 2 to receive liquid chlorine, and can be disconnected after filling. The detachable connection structure between the first filling pipe 3 and the receiving trolley 2 is an existing design. The technology will not be elaborated here. The other end of the first filling pipe 3 is connected to a liquid chlorine conveying device. Liquid chlorine in the liquid chlorine conveying device can be introduced into the filling system through the first filling pipe 3. The filling shut-off valve 4 is located between the first filling pipe 3 and the liquid chlorine conveying device. It can control the start and end of the liquid chlorine filling process. The evacuation assembly 5 is located between the first filling pipe 3 and the filling shut-off valve 4. It can evacuate the pipeline in the filling system after filling, so that its interior is in a negative pressure state. This provides power for the flow of liquid chlorine in the filling system during filling. It can also extract the liquid chlorine remaining in the filling system after filling to maintain the cleanliness of the filling system.

[0024] In some embodiments, a filling regulating valve 6 is also included. One end of the filling regulating valve 6 is connected to the filling cut-off valve 4, and the other end is connected to the first filling pipe 3 and the evacuation assembly 5. By adjusting the opening of the filling regulating valve 6, the flow rate of liquid chlorine in the first filling pipe 3 can be adjusted, thereby adjusting the filling speed.

[0025] In some embodiments, a filling flow meter 7 is also included. One end of the filling flow meter 7 is connected to the filling shut-off valve 4, and the other end is connected to the filling regulating valve 6. It can monitor the filling liquid chlorine flow rate of the filling system in real time, which facilitates the control of the liquid chlorine filling flow rate.

[0026] In some embodiments, the evacuation assembly 5 includes an evacuation pipe 51, an evacuation valve 52, and a pressure sensor 53. One end of the evacuation pipe 51 is located between the filling regulating valve 6 and the first filling pipe 3, and the other end is connected to an external evacuation device. The external evacuation device and the evacuation pipe 51 can be used to evacuate the filling system to maintain the pressure inside the filling system. The evacuation assembly 5 also includes an evacuation valve 52, which is located between the evacuation pipe 51 and the external evacuation device. The evacuation valve 52 can control the connection and closure between the external evacuation device and the evacuation pipe 51, thereby realizing the opening and closing of the vacuum in the filling system. One end of the pressure sensor 53 is connected to the evacuation pipe 51, and the other end is connected to the evacuation valve 52. The pressure sensor 53 can monitor the internal pressure of the pipe in real time so that the internal pressure of the pipe reaches the set value after filling stops.

[0027] In some embodiments, a second filling tube 8 is also included. One end of the second filling tube 8 is detachably connected to the receiving tank 2, and the other end is connected to the evacuation assembly 5. The second filling tube 8 can serve as a backup filling tube, and can simultaneously fill the first filling tube 3 and the second filling tube 8, thereby improving filling efficiency.

[0028] In some embodiments, both the first filling pipe 3 and the second filling pipe 8 can be loading arms. A loading arm is a type of pipe that can extend and move, and has advantages such as high safety and flexibility. Through the extension and movement of the pipe, it is easy to connect and disconnect with the receiving truck.

[0029] In some embodiments, a control system 9 is also included. The control system 9 is electrically connected to the weighing instrument 1, the filling shut-off valve 4, the evacuation valve 52, the pressure sensor 53, the filling regulating valve 6, and the filling flow meter 7. The control system 9 can realize the automated control of the filling system. The control system 9 may include a controller, a display, and other structures, which are existing technologies and will not be described in detail here. The control system 9 can be wirelessly connected to the weighing instrument 1, the filling shut-off valve 4, the evacuation valve 52, the pressure sensor 53, the filling regulating valve 6, and the filling flow meter 7, which can reduce the number of connecting wires and reduce the workload of wiring during installation.

[0030] The specific working principle is as follows:

[0031] The control system 9 collects the pressure, filling flow rate, and weight of the receiving tank 2 in real time through the pressure sensor 53, filling flow meter 7, and weighing instrument 1.

[0032] The control system 9 determines whether filling can proceed based on the weight of the receiving car 2 measured by the weighing instrument 1 and the status of the evacuation valve 52 (whether it is closed), and calculates the amount that can be filled. If the evacuation valve 52 is not closed, the control system 9 outputs a signal to close the evacuation valve 52.

[0033] Once it is confirmed that filling is possible, the control system 9 outputs a signal to open the filling cut-off valve 4 and the filling regulating valve 6, and the filling process begins.

[0034] The filling flow rate is monitored in real time by the filling flow meter 7, and the opening of the filling regulating valve 6 is adjusted according to the filling speed.

[0035] When the filling amount reaches the set value, the control system 9 outputs a signal to close the filling cut-off valve 4 and the filling regulating valve 6, thus ending the filling process.

[0036] After confirming that the valve of the receiving tank 2 is closed, the control system 9 outputs a signal to open the evacuation valve 52 to evacuate the filling pipeline.

[0037] Once the pressure sensor 53 returns the set value, the vacuum valve 52 is closed, and the filling is complete.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
