[0012] Beneficial effects of the utility model:

[0013] The constant-pressure automatic unloading device for corrosive liquid materials, during the unloading process of the corrosive liquid material, first uses a controller to control the opening and closing of the valve on the pipeline, then flushes high-pressure nitrogen into the tank body of the tank truck. The corrosive chemical liquid inside the tank body of the tank truck is propelled by the high-pressure nitrogen to flow through the circulation pipeline into the liquid storage tank, completing the unloading work. This method adopts automatic control during the unloading process, reducing direct human participation in the unloading process of the corrosive liquid material, thereby greatly reducing the safety risks of the operators. In addition, the inert property of nitrogen is used, and it is not easy to react with other gases and liquids, further increasing the safety of unloading.

The automated operation of the cleaning component reduces manual intervention, improves work efficiency and safety, and at the same time reduces the corrosive effect of corrosive liquid remaining on the inner wall of the liquid storage tank, thereby increasing the service life of the tank.

[0024] like Figures 1 to 4 As shown, a constant-pressure automatic unloading device for corrosive liquid materials comprises a tank truck 1 for conveying corrosive liquid materials and a liquid storage tank 12 for storing corrosive liquid materials, a nitrogen pressure valve 6 is provided on one side of the upper end of the tank body of the tank truck 1, a vent valve 5 is provided in the middle of the upper end of the tank body of the tank truck 1, a discharge valve 2 is provided at the lower end of the end surface of the tank body of the tank truck 1 close to the liquid storage tank 12, a feed pipe 8 is fixedly connected to one side of the upper end of the liquid storage tank 12, a first feed valve 7 is provided at the lower end of the first feed valve 7, a discharge hose 3 is fixedly connected to the lower end of the first feed valve 7, and the end of the discharge hose 3 away from the first feed valve 7 is flange-connected to the discharge valve 2, a remote liquid level transmitter 9 is provided on one side of the liquid storage tank 12, a breathing valve 25 is provided on the side of the upper end of the liquid storage tank 12 away from the feed pipe 8, a controller 13 is provided in the middle of the outer wall of the liquid storage tank 12, and a discharge pipe 16 is fixedly connected to the lower end of the liquid storage tank 12;

[0025] During the unloading process of corrosive liquid materials, the device first uses the controller 13 to control the opening and closing of the valve on the pipeline, and then flushes high-pressure nitrogen into the tank body of the tank truck 1. The corrosive chemical liquid inside the tank body of the tank truck 1 is pushed by the high-pressure nitrogen to flow through the circulation pipeline to the liquid storage tank 12, completing the unloading work. This method adopts automatic control during the unloading process, reducing direct human participation in the unloading process of corrosive liquid materials, thereby greatly reducing the safety risks of operators. In addition, the inert property of nitrogen is used, and it is not easy to react with other gases and liquids, further increasing the safety of unloading.

[0026] Further, such as Figure 1 As shown, a first remote pressure transmitter 4 is provided on one side of the upper end of the tank body of the tank truck 1, and a second remote pressure transmitter 11 is provided on the middle part of the upper end of the liquid storage tank 12;

[0027] The pressure inside the tank body on the tank truck 1 is detected by the first remote pressure transmitter 4, and the pressure inside the liquid storage tank 12 is detected by the second remote pressure transmitter 11. The detection results can be transmitted back to the terminal using the controller 13, so that during the unloading process, the staff can view the pressure conditions inside the two tank bodies in real time in a safe area, ensuring the normal progress of the unloading work while ensuring safety.

[0028] Further, such as Figure 1 As shown, a discharge valve 14 is provided in the middle of the discharge pipe 16, and a material pump 15 is provided at the tail end of the discharge pipe 16;

[0029] When it is necessary to extract the liquid material inside the liquid storage tank 12, the controller 13 is used to open the discharge valve 14 and the material pump 15. The material pump 15 generates suction, which can extract the corrosive liquid inside the liquid storage tank 12 through the discharge pipe 16. No manual operation is required, which improves the convenience of use.

[0030] Further, such as Figures 1 to 4 As shown, the controller 13 is electrically connected to the first remote pressure transmitter 4, the vent valve 5, the nitrogen pressure valve 6, the discharge valve 2, the first feed valve 7, the remote liquid level transmitter 9, the second feed valve 10, the second remote pressure transmitter 11, the breathing valve 25, the discharge valve 14 and the material pump 15;

[0031] The controller 13 on the device is equipped with a processing module and a transmitting module, which are electrically connected to the valves and detection elements on the corrosive liquid material conveying pipeline, so that the staff can view the various parameters of the device in real time during unloading at the terminal, ensuring the normal progress of the unloading work, which greatly improves the convenience of using the device.

[0032] Further, such as Figures 2 to 4 As shown, a cleaning assembly is provided on one side of the upper end of the liquid storage tank 12, and the cleaning assembly is used to clean the inner wall of the liquid storage tank 12. The cleaning assembly includes a bracket 20 fixedly connected to one side of the upper end surface of the liquid storage tank 12, and a servo motor 21 is provided on the upper end of the bracket 20. A connecting block 22 is fixedly connected to the middle part of the lower end surface of the bracket 20. The output end of the servo motor 21 extends into the interior of the connecting block 22 and is fixedly connected to a cleaning rod 17. The cleaning rod 17 is Z-shaped and is rotatably connected to the liquid storage tank 12 and is lowered. The end is located inside the liquid storage tank 12, and a plurality of one-way nozzles 23 are provided on the side of the outer wall of the cleaning rod 17 close to the inner wall of the liquid storage tank 12. The connecting block 22 is hollow in design, and a liquid inlet pipe 18 is fixedly connected to one side of the outer wall of the connecting block 22. The middle part of the liquid inlet pipe 18 is fixedly connected to the electromagnetic control valve 19. The electromagnetic control valve 19 and the servo motor 21 are both electrically connected to the controller 13. A plurality of connecting grooves 24 are evenly spaced at the upper end of the outer wall of the cleaning rod 17, and the connecting grooves 24 are located inside the connecting block 22;

[0033] When the corrosive liquid material inside the liquid storage tank 12 is emptied and needs to be cleaned, the controller 13 sends a signal to the electromagnetic control valve 19 and the servo motor 21. Upon receiving the signal, the electromagnetic control valve 19 opens, allowing the cleaning liquid to enter the connecting block 22 through the liquid inlet pipe 18. Subsequently, the servo motor 21 is activated, and its output end drives the cleaning rod 17 to rotate inside the liquid storage tank 12. Because the cleaning rod 17 is designed in a Z shape and has multiple one-way nozzles 23 on the side of the outer wall close to the inner wall of the liquid storage tank 12, the cleaning liquid, under the action of centrifugal force, enters the one-way nozzles 23 through the connecting groove 24 and is evenly sprayed on the inner wall of the liquid storage tank 12, achieving cleaning of the inner wall. During the cleaning process, the continuous rotation of the cleaning rod 17 ensures that the cleaning liquid can cover every corner of the inner wall of the liquid storage tank 12, thereby improving the cleaning effect.
