[0002] Triazavirine (TZV) is a new broad-spectrum antiviral drug that helps delay the treatment of acute respiratory viral infections and influenza, improves health status on the first day, reduces the possibility of complications, quickly stops the clinical symptoms of coronavirus infection, prevents disease worsening, and effectively fights RNA virus infections.

[0003] In the preparation of TZV crude products, in the plate and frame pressing process, since the material particles are relatively fine, the matching plate and frame filter cloth is a 1000-mesh brush filter cloth, and the filtration is relatively slow. During the pressing process, if the pressing water pump is directly turned on and the plate and frame pressing pressure is directly increased to 19kg, it will not only damage the plate and frame diaphragm and sealing strips, reducing their service life, but also often cause material spraying, resulting in material loss and environmental pollution.

[0004] Therefore, a TZV coarse product plate and frame press device is proposed. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up the squeezing component, after the loading is completed, open the bottom valve and pressure regulating valve of the water storage tank, and start the squeezing water pump. Then, the squeezing pressure is maintained at 5kg through the pressure regulating valve to start squeezing.

[0028] See also Figure 1 、 Figure 3 The end of the mounting frame 5 away from the hydraulic telescopic rod 1 is connected to a feed pipe 4, and a circular hole 19 connected to the feed pipe 4 is opened at the center of the high-pressure diaphragm frame 3.

[0029] See also Figure 3 The water suction pipe 8 is provided with a water tank bottom valve 18, and the outlet pipe 11 is connected to the side of the squeezing water pump 9 with a check valve 10.

[0030] In this embodiment, during use, after loading is completed, the bottom valve 18 of the water storage tank and the pressure regulating valve 15 are opened, and the squeezing water pump 9 is turned on. Thereafter, the squeezing pressure is maintained at 5 kg through the pressure regulating valve 15 to start squeezing. When the filtrate of the high-pressure diaphragm frame 3 is reduced, the pressure is controlled at 10 kg through the pressure regulating valve 15 to continue squeezing. When the filtrate of the high-pressure diaphragm frame 3 is reduced, the pressure is controlled at 14 kg through the pressure regulating valve 15 to continue squeezing. When the filtrate 3 of the high-pressure diaphragm frame is reduced, the pressure is controlled at 19 kg through the pressure regulating valve 15 to continue squeezing. When the filtrate of the high-pressure diaphragm frame 3 almost stops flowing, the pressure regulating valve 15 is fully opened, and the squeezing water pump 9 and the bottom valve 18 of the water storage tank are closed.

After the loading is completed, the water tank bottom valve 18 on the suction pipe 8 and the pressure regulating valve 15 on the outlet pipe 11 are opened, and the squeezing water pump 9 is turned on. Then, the squeezing pressure is maintained at 5kg through the pressure regulating valve 15 to start squeezing. When the filtrate of the high-pressure diaphragm plate frame 3 is reduced, the pressure is controlled at 10kg through the pressure regulating valve 15 to continue squeezing. When the filtrate of the high-pressure diaphragm plate frame 3 is reduced, the pressure is controlled at 14kg through the pressure regulating valve 15 to continue squeezing. When the filtrate 3 of the high-pressure diaphragm plate frame is reduced, the pressure is controlled at 19k g Continue squeezing. When the filtrate in the high-pressure diaphragm frame 3 almost stops flowing, fully open the pressure regulating valve 15, and close the squeezing water pump 9 and the water tank bottom valve 18. By squeezing in steps, the high-pressure diaphragm frame 3 can be avoided from being damaged, the material spraying phenomenon can be avoided, the waste of materials can be reduced, and the environment can be avoided from being polluted. The check valve 10 can prevent the squeezing water from flowing back. After squeezing is completed, the water tank bottom valve 18 is closed and the pipeline pressure valve 12 is opened. The squeezing water in the high-pressure diaphragm frame 3 can flow back to the water outlet pipe 11 along the conduit 17.
