[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-4A sodium metabisulfite powder drying and conveying device includes a drying tower 1, a powder collection box 2 installed on one side of the drying tower 1, and a conveying mechanism 3 installed inside the powder collection box 2. A discharge port 102 is provided between the drying tower 1 and the powder collection box 2. A drain port 201 is provided through the bottom surface of the powder collection box 2 near the drying tower 1. A sealing door 8 is hinged to the inner wall of the drain port 201. A moving mechanism is connected to the bottom surface of the outer wall of the powder collection box 2. A support component is connected to the output end of the moving mechanism. The other end of the support component penetrates through the outer wall of the drying tower 1 to the interior of the drying tower 1. The end of the support component located outside the drying tower 1 is connected to the sealing door 8. The end of the support component located inside the drying tower 1 is connected to a sealing component. The sealing component is matched and aligned with the discharge port 102.

[0026] like Figures 1 to 4 As shown, during the cleaning process of the sodium metabisulfite powder drying and conveying device of this utility model, it is first ensured that the sodium metabisulfite powder inside the powder collection box 2 has been discharged into the drying tower 1 to avoid material waste during cleaning. Then, the moving mechanism is activated, and the output end of the moving mechanism will retract, pulling the support component and sealing component towards itself. As the support component moves, it will gradually release the limit on the sealing door 8, at which point the sealing door 8 will gradually open. As the sealing component moves, it will gradually block the discharge port 102 between the drying tower 1 and the powder collection box 2. At this time, the powder collection box 2 is then rinsed by an external rinsing device. The wastewater generated during the rinsing process can be collected at the drain port 201 and below the sealing door 8. After rinsing, the powder collection box 2 will be naturally dried by the external device. Then, the moving mechanism is controlled in reverse to open the sealing door 8 and the sealing component.

[0027] It should be noted that the drying tower 1, powder collection box 2, and conveying mechanism 3 mentioned above are all prior art disclosed in the patent "Sodium metabisulfite powder drying and conveying device" with publication number CN212720774U. Therefore, their connection methods and working principles will not be described in detail.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the moving mechanism includes a hydraulic rod 5 and two support plates 4. The upper ends of the two support plates 4 are fixedly connected to the bottom surface of the outer wall of the powder collection box 2, and the lower ends of the two support plates 4 are fixedly connected to the two ends of the outer wall of the hydraulic rod 5 respectively. The output end of the hydraulic rod 5 passes through one of the support plates 4 and is connected to the end of the support assembly located outside the drying tower 1.

[0029] More specifically, when it is necessary to clean the inside of the powder collection box 2, simply activate the hydraulic rod 5. The output end of the hydraulic rod 5 will retract, thereby pulling the support assembly and sealing assembly to move.

[0030] likeFigure 1 , Figure 2 and Figure 4 As shown, the support assembly includes a support block 6 and a connecting rod 7. One end of the support block 6 is fixedly connected to the output end of the hydraulic rod 5, and the other end of the support block 6 is fixedly connected to one end of the connecting rod 7. The other end of the connecting rod 7 passes through the outer wall of the drying tower 1 to the interior of the drying tower 1. The connecting rod 7 located inside the drying tower 1 is also connected to the sealing assembly. The upper end of the support block 6 abuts against the sealing door 8.

[0031] More specifically, when the hydraulic rod 5 is activated, the output end will pull the support block 6 to move. After the support block 6 moves, it will gradually release the squeezing limit on the upper sealing door 8. At the same time, the support block 6 will also pull the connecting rod 7 to move, so that the sealing assembly can be carried by the connecting rod 7 to seal the material discharge port 102.

[0032] like Figure 2 and Figure 4 As shown, the upper surface of the support block 6 is provided with a ramp 601, and the inclined surface of the ramp 601 abuts against the outer wall of the sealing door 8 away from the hinge.

[0033] More specifically, by setting the ramp 601, the sealing door 8 can be gradually opened when the support block 6 moves, and the sealing door 8 can be gradually closed when the support block 6 returns.

[0034] like Figures 2-4 As shown, the sealing assembly includes a sealing plate 9 and a connecting plate 10. The lower end of the connecting plate 10 is sleeved and fixedly connected to the outer wall of the connecting rod 7. The upper end of the connecting plate 10 is fixedly connected to the lower end of the sealing plate 9. The outer wall of the sealing plate 9 is slidably connected to the inner wall of the discharge port 102.

[0035] More specifically, when the connecting rod 7 moves, it pulls the connecting plate 10 to move together. When the connecting plate 10 moves, it can move the sealing plate 9 together until the sealing plate 9 is fully inserted into the discharge port 102 to seal the discharge port 102.

[0036] like Figure 2 and Figure 3 As shown, the bottom surface of the discharge port 102 is provided with an alignment port 101, and the outer wall of the connecting plate 10 is slidably connected to the inner wall of the alignment port 101.

[0037] More specifically, by setting the alignment port 101, the connecting plate 10 can be provided with support and storage, which in turn allows the sealing plate 9 to be inserted deeper into the discharge port 102, resulting in a better sealing effect.

[0038] like Figure 3As shown, a storage opening 103 is provided on the inner wall of the drying tower 1 away from the powder collection box 2, and the outer walls of the sealing plate 9 and the connecting plate 10 are slidably connected to the inner wall of the storage opening 103.

[0039] More specifically, by setting up the receiving port 103, the sealing plate 9 and the connecting plate 10 can be stored in the drying tower 1 and the powder collection box 2 during normal operation, thereby avoiding the sealing plate 9 and the connecting plate 10 from obstructing the normal falling of sodium metabisulfite powder.

[0040] like Figure 3 As shown, a material sliding slope 104 is provided on the side of the receiving port 103 near the powder collection box 2.

[0041] More specifically, because the thickness of the connecting plate 10 is less than the thickness of the sealing plate 9, some sodium metabisulfite powder may remain in the receiving port 103. In this case, by setting the sliding slope 104, this sodium metabisulfite powder can fall naturally to the bottom of the drying tower 1.

[0042] It should be noted that the same settings can be made at the opening of alignment port 101, with the same purpose and effect.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
