DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1 to Figure 6 The screw conveyor for perchloric acid production shown in the figure comprises a conveying cylinder 1, a rotating rod 4 is rotatably connected to the conveying cylinder 1, the rotating rod 4 is distributed along the axial length direction of the conveying cylinder 1, a motor 16 is fixedly connected to the end of the conveying cylinder 1, and the rotating rod 4 is fixedly connected to the driving shaft of the motor 16. Specifically, the rotation of the motor 16 drives the rotating rod 4 to rotate.

[0026] The two ends of the rotating rod 4 are respectively fixedly connected with the first spiral blade 5 and the second spiral blade 6, and the spiral directions of the first spiral blade 5 and the second spiral blade 6 are consistent to ensure the consistent conveying direction. In specific use, rubber pads can be provided on the outer spiral surfaces of the first spiral blade 5 and the second spiral blade 6 to reduce the wear between the inner wall of the conveying cylinder 1, while improving the sealing and ensuring the conveying efficiency.

[0027] One end of the conveying cylinder 1 close to the first spiral blade 5 is connected to a feed pipe 2, and one end of the conveying cylinder 1 close to the second spiral blade 6 is connected to a discharge pipe 3. When in use, perchloric acid liquid is injected through the feed pipe 2, and the conveyed liquid enters the subsequent process through the discharge pipe 3.

[0028] Considering that the perchloric acid liquid may be stratified after being left to stand for a long time, and then being transported and processed, in order to ensure the uniformity of the perchloric acid liquid, a shaking assembly is provided between the first spiral blade 5 and the second spiral blade 6, and the shaking assembly is provided in multiple groups, and the multiple groups of shaking assemblies are evenly distributed around the rotating rod 4. The shaking assembly includes a support plate 7 and an elastic sheet 8, the support plate 7 is fixedly connected to the rotating rod 4, the elastic sheet 8 is fixedly connected to the end of the support plate 7 away from the rotating rod 4, the elastic sheet 8 is S-shaped, and a through groove 9 is provided on the elastic sheet 8.

[0029] During operation, when the elastic sheet 8 and the support plate 7 rotate with the rotating rod 4, the liquid will be stirred; at the same time, affected by the liquid resistance, the elastic sheet 8 will shake, accelerating the liquid stirring amplitude, making the internal composition of the perchloric acid liquid more uniform, facilitating subsequent production, and realizing the shaking function.

[0030] The elastic sheet 8 is S-shaped, which can expand the contact area and improve the shaking efficiency; at the same time, when the liquid passes through the through groove 9, it will drive the elastic sheet 8 to shake.

[0031] In order to filter out impurities in perchloric acid, a filter plate 10 is provided on the side of the first spiral blade 5 facing away from the second spiral blade 6. The filter plate 10 is fixedly connected to the inside of the conveying cylinder 1, and a round hole is provided on the filter plate 10 for the rotating rod 4 to pass through. When the perchloric acid liquid passes through the filter plate 10, the impurities inside it will adhere to and accumulate on the filter plate 10, thereby achieving a filtering function.

[0032] In order to clean the impurities on the filter plate 10 and ensure the conveying efficiency, a filter box 11 is provided on the side of the filter plate 10 facing away from the first spiral blade 5. The filter box 11 is fixedly connected to the rotating rod 4. A square groove 13 is provided on the filter box 11. A push block 12 is fixedly connected to the outer wall of the filter box 11. The push block 12 is in the shape of a triangular prism and slides on the filter plate 10. The push block 12 cooperates with the square groove 13. When the filter box 11 rotates, the push block 12 and the square groove 13 are at the front end of the rotation direction. During operation, the rotating rod 4 drives the filter box 11 to rotate, and the push block 12 is attached to the filter plate 10 to push and scrape. Impurities enter the interior of the filter box 11 from the square groove 13, and the impurities are cleaned, so as to avoid clogging of the filter plate 10 and ensure the conveying efficiency.

[0033] Considering that when the filter box 11 rotates, the liquid will also enter the interior of the filter box 11 through the square groove 13, and the filter box 11 is also provided with a plurality of filter holes with smaller inner diameters for the liquid to pass through while preventing impurities from passing through.

[0034] Considering that after shutdown, impurities inside the filter box 11 are easily scattered from the square groove 13, a sealing block 14 is provided inside the filter box 11, and the sealing block 14 is sealed with the square groove 13. A spring 15 is provided inside the filter box 11, one end of the spring 15 is fixedly connected to the sealing block 14, and one end of the spring 15 is fixedly connected to the inner wall of the filter box 11.

[0035] During operation, the rotating rod 4 drives the filter box 11 to rotate, and the sealing block 14 slides toward the inside of the filter box 11 due to the resistance of the liquid, so that the square groove 13 is opened, and impurities can enter the inside of the filter box 11 through the gap between the square groove 13 and the sealing block 14. When the filter box 11 stops rotating, the restoring force of the spring 15 resets the sealing block 14 and closes the square groove 13.
