DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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] like Figure 1-Figure 4 As shown, a powder collection and transfer device includes a fixed frame 2, a plurality of universal wheels 3 are distributed at the bottom of the fixed frame 2, and also includes a hollow warehouse body 1 and a transfer bucket 7. The universal wheels 3 are used to transfer the hollow warehouse body 1 and the transfer bucket 7;

[0026] The hollow warehouse body 1 is fixedly connected to the upper end of the fixed frame 2, and an extraction pipe 4 is rotatably connected through the top of the hollow warehouse body 1, and the end of the extraction pipe 4 extends to the bottom of the hollow warehouse body 1. A driving structure is provided between the hollow warehouse body 1 and the extraction pipe 4, and the driving structure is used to drive the extraction pipe 4 to rotate. A scraper 21 is connected to the side of the extraction pipe 4, and the scraper 21 is in contact with the inner wall of the hollow warehouse body 1. The scraper 21 is used to scrape off the activated carbon powder adhered to the inner wall of the hollow warehouse body 1, and a lifting structure is provided on the outer wall of the hollow warehouse body 1;

[0027] The transfer bucket 7 is movably connected to the hollow warehouse body 1 through a lifting structure. The lifting structure is used to adjust the height of the transfer bucket 7. A suction component is arranged on the top of the transfer bucket 7. A hose 6 is fixedly connected to the side wall of the transfer bucket 7. A valve is fixedly arranged at the bottom of the transfer bucket 7 to facilitate the control of opening or closing of the transfer bucket 7. A connecting pipe 5 is connected to the end of the hose 6 away from the transfer bucket 7. The connecting pipe 5 is rotatably connected to the top of the extraction pipe 4. The connecting pipe 5 is connected to the top of the hollow warehouse body 1 through fixed rods on both sides to prevent the extraction pipe 4 from driving the connecting pipe 5 and the hose 6 to rotate when rotating, thereby causing the hose 6 to be entangled.

[0028] In some specific embodiments, such as Figure 2 or Figure 3 As shown, in order to facilitate the transfer of activated carbon powder in the hollow warehouse body 1 into the transfer bucket 7, the suction component includes a filter plate 18 and a vacuum pump 15, a cover cap 14 is provided on the top of the transfer bucket 7, a pressure ring 16 is provided at the bottom of the transfer bucket 7, a placement groove 17 is provided on the top of the transfer bucket 7, a filter plate 18 is provided between the placement groove 17 and the pressure ring 16, the filter plate 18 is composed of a filter mesh and breathable cotton, the breathable cotton is fixed at one end of the filter plate 18 away from the hollow warehouse body 1, the breathable cotton only allows airflow to pass, and the powder is blocked and stored in the transfer bucket 7, the top of the cover cap 14 is connected with a vacuum pump 15, and a connecting bolt 19 is provided between the transfer bucket 7 and the cover cap 14. The filter plate 18 can be taken out by removing the connecting bolt 19 for easy cleaning.

[0029] When the activated carbon powder needs to be transferred, the interior of the transfer bucket 7 is evacuated through the vacuum pump 15, the hose 6 and the extraction pipe 4, so that the interior of the transfer bucket 7 is in a negative pressure state. Under the negative pressure state, the activated carbon powder follows the air flow into the interior of the transfer bucket 7, and the filter plate 18 on the top of the transfer bucket 7 can fully filter the activated carbon powder. The gas is discharged from the vacuum pump 15, and the activated carbon powder remains in the interior of the transfer bucket 7, so that the activated carbon powder in the transfer bucket 7 can be subsequently transferred to other storage containers.

[0030] In some specific embodiments, such as Figure 2As shown, in order to facilitate the alignment of the discharge port of the transfer bucket 7 with the feed port of the container of the next process, the lifting structure includes a fixed box 8, a motor 12 and a moving block 9. The fixed box 8 is connected to the side of the hollow warehouse body 1, and the fixed box 8 is provided with an opening on the side away from the hollow warehouse body 1. The fixed box 8 is vertically rotatably connected with a screw 10 inside. The motor 12 is fixed at the bottom of the fixed box 8, and the output end of the motor 12 is connected to the screw 10. The moving block 9 is fixedly connected to the side wall of the transfer bucket 7. The screw 10 passes through the moving block 9 and is threadedly connected to the moving block 9. The moving block 9 is slidably connected inside the fixed box 8. Starting the motor 12 drives the screw 10 to rotate, so that the moving block 9 can slide up and down along the fixed box 8. The moving block 9 drives the transfer bucket 7 to move up and down, so that the discharge port of the transfer bucket 7 can be aligned with the feed port of the container of the next process.

[0031] In some specific embodiments, such as Figure 4 As shown, in order to prevent the weight of the transfer bucket 7 from damaging the screw 10, two vertical limit rods 11 are fixed on the inner side of the fixed box 8. The limit rods 11 are located on both sides of the screw 10. The limit rods 11 include convex strips 13 arranged on both sides thereof. The limit rods 11 penetrate the moving block 9 and are slidably connected to the moving block 9. The limit rods 11 can be used not only to guide the moving block 9, but also to support the moving block 9, so as to prevent one side of the moving block 9 from being too heavy and tilting, thereby damaging the thread on the outer side of the screw 10.

[0032] In some specific embodiments, such as Figure 1 As shown, in order to facilitate driving the scraper 21 to scrape off the activated carbon powder adhered to the side wall, the driving structure includes a driven gear 22, a driving gear 23 and a motor 24. The motor 24 is fixedly connected to the top of the hollow warehouse body 1, and the output end of the motor 24 is connected to the top of the driving gear 23. The driven gear 22 is fixed to the outside of the extraction tube 4. The side of the extraction tube 4 is connected to the support rod 20. The scraper 21 is connected to the end of the support rod 20 away from the extraction tube 4. The scraper 21 is in contact with the inner wall of the hollow warehouse body 1, and the driven gear 22 is meshed with the driving gear 23.

[0033] In some specific embodiments, such as Figure 2 As shown, in order to facilitate the absorption of the activated carbon powder inside the hollow warehouse body 1, the bottom of the hollow warehouse body 1 is funnel-shaped, and the bottom of the extraction tube 4 extends to the lowest end of the hollow warehouse body 1. When there is still a small amount of activated carbon powder inside the hollow warehouse body 1, since the bottom of the hollow warehouse body 1 is funnel-shaped, the activated carbon powder will gather at the bottom of the hollow warehouse body 1 for absorption by the extraction tube 4.

[0034] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0035] When the activated carbon powder needs to be transported, the hollow warehouse body 1 is first moved to the vicinity of the storage container by the universal wheel 3, and then the motor 12 is started to drive the screw 10 to rotate, so that the moving block 9 slides up and down along the limit rod 11, and the moving block 9 drives the transfer bucket 7 to adjust to an appropriate height, so that its bottom is stuck in the feeding pipe of the storage container, and then the vacuum pump 15 is started, and the activated carbon powder in the transfer barrel is sucked into the transfer bucket 7 through the hose 6 and the extraction pipe 4, and then the valve of the transfer bucket 7 is opened to make it fall into the storage container. When the powder inside the hollow warehouse body 1 is sucked, the transfer bucket 7 is started. Motor 24, Motor 24 drives the driving gear 23 to rotate, and the driven gear 22 meshing therewith also rotates accordingly. During the rotation of the extraction tube 4 driven by the driven gear 22, the scraper 21 scrapes the inner wall of the hollow warehouse body 1 to prevent the activated carbon from adhering to the inner wall of the hollow warehouse body 1, resulting in incomplete discharge. When the activated carbon powder is discharged, the filter plate 18 is set to prevent the activated carbon powder from entering the vacuum pump 15. When the filter plate 18 needs to be disassembled, the connecting bolts 19 are removed, and the cap 14 is opened to disassemble the filter plate 18 for easy cleaning.

[0036] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
