Description

Technical Field

[0001] The utility model relates to the field of chemical production equipment and technology, in particular to a device for automatic filling of yellow phosphorus. Background Art

[0002] Yellow phosphorus is an important chemical raw material, widely used in a variety of industries, including pesticides, pharmaceuticals, and dyes. However, due to its strong chemical activity and flammability, safety issues are particularly prominent during its production and transportation. Traditional manual operations, particularly during the filling process, present numerous safety risks.

[0003] Currently, the filling of yellow phosphorus typically requires one worker to start the phosphorus pump in the yellow phosphorus storage area, while another worker monitors the filling process at the yellow phosphorus tanker truck, ensuring that any abnormalities can be immediately stopped. This operating mode is not only inefficient but also increases the risk of workers being exposed to hazardous environments. It is also not conducive to accurately controlling the filling volume, which can easily cause yellow phosphorus leakage, which in turn can cause serious safety accidents such as fires or even explosions. In addition, traditional filling methods face the following challenges:

[0004] 1. Manual monitoring cannot guarantee a quick response in an emergency, and poses a significant safety hazard.

[0005] 2. Relying on manual judgment and operation can easily lead to deviations in filling volume, affecting product quality;

[0006] 3. Long hours of manual supervision increase the burden on workers and are not conducive to improving production efficiency;

[0007] 4. For different types of tank trucks, manual adjustment of the filling position is time-consuming and labor-intensive, and has limited adaptability. Utility Model Content

DETAILED DESCRIPTION

[0027] like Figure 1 As shown, a device for automatic yellow phosphorus filling includes a yellow phosphorus storage tank 1, a feed pipe 2, a hot water pipe 3, a steam pipe 4, a metal hose 22 and a crane pipe 11. One end of the feed pipe 2 is connected to the yellow phosphorus storage tank 1, and the other end of the feed pipe 2 is connected to the liquid inlet of the main pneumatic valve 10. One end of the hot water pipe 3 is connected to an external hot water system, and the other end of the hot water pipe 3 is connected to the liquid inlet of the main pneumatic valve 10. One end of the steam pipe 4 is connected to the external steam system, and the other end of the steam pipe 4 is connected to the liquid inlet of the main pneumatic valve 10. The liquid outlet of the main pneumatic valve 10 is connected to the crane pipe 11 through the metal hose 22. When the device is working, the crane pipe 11 extends into the tank truck 12 for filling.

[0028] The feed pipe 2 is provided with a third pneumatic valve 9 , the hot water pipe 3 is provided with a second pneumatic valve 8 , and the steam pipe 4 is provided with a first pneumatic valve 7 ; the feed pipe 2 is provided with a flow meter 6 and a feed pump 5 .

[0029] The operating principle of the device is as follows:

[0030] 1. After the tank truck 12 arrives at the filling port, the horizontal drive system on the crane pipe 11 will drive the crane pipe 11 to move above the tank truck 12, and the vertical drive system will insert the crane pipe 11 into the tank truck 12;

[0031] 2. The remote control center opens the second pneumatic valve 8 and the main pneumatic valve 10, and hot water is transported to the tank truck 12 through the hot water pipe 3 and the metal hose 22;

[0032] 3. After 3 minutes, close the second pneumatic valve 8 and open the first pneumatic valve 7 at the same time to preheat the pipeline and tank truck. After the temperature inside the tank truck reaches 50°C, close the second pneumatic valve 8;

[0033] 4. The operator remotely inputs the volume V of yellow phosphorus to be loaded in the central control room. The system automatically opens the third pneumatic valve 9 and the main pneumatic valve 10, starts the feed pump 5 and begins automatic canning. When the input volume is reached, the feed pump 5 is automatically stopped, and the third pneumatic valve 9 and the main pneumatic valve 10 are closed at the same time, and the canning is completed.

[0034] The preferred solution is Figure 2 and Figure 3 As shown, a chassis 13 is provided at the end of the crane tube 11, and an anti-collision rod 15 is vertically provided on the lower end surface of the chassis 13. The anti-collision rod 15 is annularly symmetrically arranged around the axis of the crane tube 11, and a vibration sensor 14 is provided at the end of the anti-collision rod 15;

[0035] When the crane pipe 11 collides with the tank wall or other hard objects during the descent process, the anti-collision rod 15 will feed back the vibration to the vibration sensor 14. The vibration sensor 14 sends a signal to the remote monitoring center and triggers the limit switch to stop the crane pipe 11 from descending to protect the equipment.

[0036] The preferred solution is Figure 2 and Figure 3 As shown, a first connecting rod 16 is vertically provided on the lower end surface of the chassis 13, and a thermometer 23 is provided on the end of the first connecting rod 16; when the crane pipe 11 is extended into the interior of the tank truck 12, the thermometer 23 can monitor the internal temperature of the tank truck, and when the temperature inside the tank truck 12 reaches 50°C, the steam preheating is immediately stopped.

[0037] The preferred solution is Figure 2 and Figure 3 As shown, a second connecting rod 17 is vertically provided on the lower end surface of the chassis 13, and a float 18 is sleeved on the second connecting rod 17. Contact switches 19 are correspondingly provided at the end of the second connecting rod 17 and the upper end surface of the float 18. During the filling process, the float 18 will slide upward along the second connecting rod 17 as the liquid level rises. When the filling is full, the float 18 moves to the upper end of the second connecting rod 17 and makes the contact switch 19 contact with each other. The contact switch 19 immediately sends a command signal to the remote monitoring center and stops filling.

[0038] The preferred solution is Figure 2 and Figure 3As shown, a positioning sensor 20 is provided at the lower end surface of the chassis 13. The positioning sensor 20 is arranged symmetrically around the axis of the crane pipe 11 to accurately locate the filling port.

When the crane pipe 11 moves downward to the specified position, the pressure sensing ring 21 will be against the filling port of the tank truck 12. At this time, the pressure sensing ring 21 immediately sends a feedback signal to the monitoring center and stops the crane pipe 11 from moving downward.
