[0034] Refrigerant preparation: filling the refrigerant containing high moisture into a preliminary storage device, and connecting the storage device with the input end of the dryer;

[0036] Refrigerant storage: connecting the output end of the dryer with the storage tank, passing the dehydrated refrigerant into the refrigerant storage tank, and transporting the refrigerant to the finished product tank after passing the analysis (refrigerant moisture ≤5PPm), to complete the dehydration and storage of the refrigerant.

[0037] Specifically, the refrigerant containing high moisture is preliminarily dehydrated by the dryer (filled with high-moisture removal adsorbent) and then passed into the next group of dryers (filled with low-moisture removal adsorbent) to remove the moisture in the refrigerant to below 5PPm, and then passed into the refrigerant storage tank, and transported to the finished product tank after passing the analysis (refrigerant moisture ≤5PPm), to save the operation process of transporting the refrigerant from the detection tank to the storage tank; save the operation process of opening the circulating pump of the storage tank to circulate the refrigerant for dehydration, reduce the labor cost, save the operation process of transporting the refrigerant from the detection tank to the storage tank; save the operation process of opening the circulating pump of the storage tank to circulate the refrigerant for dehydration, reduce the maintenance cost of the moving equipment and the power consumption, save the sampling and analysis process of the refrigeration detection tank; save the analysis cost.

[0044] The upper sealing plate 5 comprises a square plate 51 and a plurality of fixed protrusions 52 fixedly installed on the outer walls of the square plate 51, and the square plate 51 is fixedly installed at the upper end of the inner cavity of the drying cavity 11 through the fixed protrusions 52.

[0045] The lower sealing plate 6 comprises a lower sealing plate main body 61 and a plurality of T-shaped sliding blocks 62 fixedly installed on the outer walls of the two sides of one end of the lower sealing plate main body 61, the top surfaces of the two sides of one end of the lower sealing plate main body 61 are respectively embedded with slidingly installed push blocks 63, the push blocks 63 are elastically slidingly installed in the inner cavity of the lower sealing plate main body 61 through connecting springs 65, the top surfaces of the two sides of one end of the lower sealing plate main body 61 are also respectively slidingly inserted with trapezoidal clamping blocks 64, the lower end of the trapezoidal clamping block 64 is installed on the push block 63, the T-shaped sliding blocks 62 are respectively slidingly arranged in the T-shaped sliding grooves 14, the middle part of the lower sealing plate main body 61 is provided with a through hole 611, the top surfaces of the two sides of the lower sealing plate main body 61 are respectively provided with double-pass T-shaped sliding grooves 612, the inner walls of one end of the inner cavities of the double-pass T-shaped sliding grooves 612 are provided with inner sliding grooves 613, the push blocks 63 are slidingly inserted in the inner sliding grooves 613, the top surfaces of the two sides of one end of the lower sealing plate main body 61 are respectively provided with top sliding grooves 614, the top sliding grooves 614 are respectively connected with the inner sliding grooves 613, the trapezoidal clamping blocks 64 are slidingly arranged in the top sliding grooves 614, the top surfaces of the two sides of one end of the push blocks 63 are provided with double-pass push grooves 631, the inner walls of the inner cavities of the double-pass push grooves 631 are respectively provided with inclined sliding grooves 632, the outer walls of the two sides of the lower end of the trapezoidal clamping block 64 are respectively fixedly installed with driving shafts 641, and the driving shafts 641 are respectively slidingly arranged in the inclined sliding grooves 632.

Then the output end of the electric cylinder 3 drives the drying frame 4 to continue to move forward until the drying frame 4 moves out of the lower sealing plate 6. At this time, the moisture adsorbent filled in the drying frame 4 can be discharged from the bottom of the drying frame 4, which is automatic. The degree of automation is high. The drying frame 4 can be automatically discharged without manual touch.

The limiting sliding blocks 711 are respectively slidingly arranged in the limiting inner sliding grooves 723.

[0048] Specifically, when the water adsorbent discharging is completed, the output end of the electric cylinder 3 drives the drying frame 4 to move into the inner cavity of the drying chamber 11, at this time, the lower sealing plate 6 will not move under the action of friction resistance, when the drying frame 4 moves to the lower sealing plate 6, the lower sealing plate 6 seals the bottom of the drying frame 4, at this time, the staff can add water adsorbent to the cavity formed between the outer frame 41 and the inner frame 42 after the electric cylinder 3 is turned off, after the cavity formed between the outer frame 41 and the inner frame 42 is filled, the staff can continue to start the electric cylinder 3, the output end of the electric cylinder 3 continues to drive the drying frame 4 to move into the inner cavity of the drying chamber 11, under the limiting action of the protruding end of the trapezoidal clamping block 64, the drying frame 4 drives the lower sealing plate 6 to move into the inner cavity of the drying chamber 11 together, until the T-shaped sliding block 62 slides to the end of the T-shaped sliding groove 14, the trapezoidal clamping block 64 is reconnected into the triangular clamping groove 413, and the sealing plate 7 also seals the discharge port 12, the replacement of the water adsorbent is completed, the degree of automation is high, one pushing action of the electric cylinder 3 can complete multiple effects at the same time, the replacement efficiency of the water adsorbent is improved, and use is facilitated.
