Detailed Implementation

[0016] like Figures 1 to 3As shown, a crude heparin sodium drying device includes a horizontally arranged tank 1. An inlet pipe, an outlet pipe 3, a vacuum line 4, and a heating plate 5 are provided on the tank 1. A ball valve 18 is installed on the outlet pipe 3. A T-shaped groove 6 is horizontally formed on the outlet pipe 3. A sealing plug 2 is bolted to one end of the T-shaped groove 6. A moisture-absorbing plate assembly is slidably inserted into the T-shaped groove 6, positioned above the ball valve 18. The moisture-absorbing plate assembly is used to absorb moisture from the outlet pipe 3. The moisture-absorbing plate assembly is connected to a positioning component, which defines the position of the moisture-absorbing plate assembly.

[0017] like Figure 3 and 4 As shown, the moisture-absorbing insert assembly includes a moisture-absorbing box 7 with openings at both the top and bottom. The moisture-absorbing box 7 is slidably connected to the T-shaped through groove 6. Both the top and bottom ends of the moisture-absorbing box 7 are covered with perforated cover plates 17. Calcium oxide particles 8 are placed inside the moisture-absorbing box 7. To facilitate the replacement of the calcium oxide particles 8, the moisture-absorbing box 7 and the perforated cover plates 17 are connected by bolts.

[0018] like Figures 2 to 4 As shown, the positioning component includes a slider 10, which is fixedly installed on the moisture-absorbing box 7. The slider 10 is slidably connected to the T-shaped through groove 6. A spring groove 11 is horizontally provided at the outer end of the slider 10. A connecting groove 12 is provided on both sides of the slider 10, and the connecting groove 12 is connected to the spring groove 11. Two operating plates 9 are slidably connected in the spring groove 11, and a compression spring 16 is horizontally provided between the two operating plates 9.
