[0024] The following will clearly and completely describe the technical solutions of the present invention through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 4The present embodiment provides a drying device for adsorbent, comprising a hollow outer cylinder 1, wherein the inner cavity of the outer cylinder 1 is provided with a vertical pipe 2 and an inner cylinder 3 coaxially distributed in the vertical direction, and air holes 31 are evenly distributed on the surface of the inner cylinder 3, wherein the inner cylinder 3 is located between the vertical pipe 2 and the outer cylinder 1, and a drying chamber 4 for accommodating the adsorbent is formed between the inner cylinder 3 and the outer cylinder 1, and the inner cylinder 3 and the vertical pipe 2 form a hot air input chamber 5, the inner cylinder 3 is connected to a hot air input pipe 6 communicating with the hot air input chamber 5, and the hot air input pipe 6 is connected to a hot air input device 7; a lifting screw 8 is provided for rotation inside the vertical pipe 2, an inlet 21 communicating with the lower part of the drying chamber 4 is provided at the lower part of the vertical pipe 2, and a lead-out port 22 communicating with the upper part of the drying chamber 4 is provided at the upper part of the vertical pipe 2; a feeding assembly for adding adsorbent is provided at the top of the outer cylinder 1, and a discharge mechanism for discharging adsorbent is provided at the bottom of the vertical pipe 2. In this way, the hot air can be directly input into the hot air input chamber through the hot air input pipe, and then can be evenly emitted from the inside to the outside through the air vents distributed on the surface of the inner cylinder, so that the adsorbent put into the drying chamber can be evenly dried; by setting the lifting screw, the adsorbent can be lifted from bottom to top during the drying process, so that the adsorbent has a dynamic cycle and flipping process, which is not easy to stick together, greatly promoting uniform drying and improving the drying effect; when the drying process is completed, it is only necessary to drive the lifting screw in reverse and open the discharge mechanism to discharge the dried adsorbent outward.

[0026] In some specific embodiments, reference Figure 1 and Figure 3 The upper portion of the vertical tube 2 is fixedly connected to the top of the outer tube 1, and the lower portion of the vertical tube 2 is fixedly connected to the bottom of the outer tube 1. The ends of the lifting screw 8 are rotatably connected to the upper and lower portions of the vertical tube 2 via bearing seats 82, respectively. The top of the outer tube 1 is provided with a motor 9 connected to the upper end of the lifting screw 8. More specifically, the lifting screw 8 includes a rotating shaft 83 and auger blades 84 spirally distributed along the surface of the rotating shaft 83.

[0027] In some specific embodiments, reference Figure 1 and Figure 3The inner cylinder 3 includes an upper inner cylinder section 32 located at the top, a lower inner cylinder section 33 located at the bottom, and a middle inner cylinder section 34 located in the middle. The upper end of the middle inner cylinder section 34 is fixedly connected to the lower end of the upper inner cylinder section 32, and the lower end of the middle inner cylinder section 34 is fixedly connected to the upper end of the lower inner cylinder section 33. The end of the hot air input pipe 6 near the hot air input chamber 5 is connected to the middle of the middle inner cylinder section 34. In this way, the input hot air can penetrate and diffuse relatively evenly from the inside to the outside. Specifically, the middle inner cylinder section 34 is cylindrical, the upper inner cylinder section 32 is conical, and the lower inner cylinder section 33 is in the shape of an inverted cone. In this way, the conical shape of the upper inner cylinder section can facilitate the rapid drop of the adsorbent after it re-enters the drying chamber through the outlet, and will not accumulate on top of the inner cylinder. The lower portion of the outer cylinder 1 is in the shape of an inverted cone, so that the adsorbent in the drying chamber can be quickly guided and slid toward the inlet by utilizing the conical surface.

[0028] In some specific embodiments, reference Figure 1 The feed assembly includes a feed port 11 provided at the top of the outer cylinder 1, a feed hopper 12 connected to the feed port 11, and a sealing cover 13 covering the feed hopper 12. In this way, the adsorbent to be dried can be added to the drying chamber inside the outer cylinder through the feed hopper.

[0029] In some specific embodiments, reference Figure 1 and Figure 3 The discharge mechanism includes a discharge port 23 provided on the bottom side wall of the vertical pipe 2, slots 24 located on both sides of the discharge port 23, and baffles 25 plugged into the slots 24. By plugging and unplugging the baffles, the discharge port can be quickly opened or closed to discharge the adsorbent that has completed the drying process.

[0030] In some specific embodiments, reference Figure 1 and Figure 2 The hot air input device 7 includes a heating box 71 and a blower 72. The inner cavity of the heating box 71 is provided with a heating wire 73. The air inlet of the heating box 71 is connected to the blower 72, and the air outlet of the heating box 71 is connected to the hot air input pipe 6. In this way, the air blown in by the blower can be heated, thereby continuously providing hot air, which is then transported to the inner cylinder through the hot air input pipe.

[0031] In some specific embodiments, reference Figure 1 The top of the outer cylinder 1 is provided with an exhaust port 14, to which an exhaust fan 15 is mounted. A mesh cover is provided at the end of the exhaust fan 15 near the drying chamber 4. The exhaust fan provides suction to expel the air containing water vapor from the outer cylinder; the mesh cover prevents the adsorbent from being sucked out by the exhaust fan.

[0032] As an improved implementation method, refer to Figure 1 and Figure 3 The lifting screw 8 is provided with a material-prying piece 81 near the outlet 22, so that the adsorbent lifted to the upper part of the vertical pipe by the lifting screw can be pried out to avoid clogging of the adsorbent at the outlet.

[0033] As an improved implementation method, Figure 1 As shown, the outer cylinder 1 is a double-layer shell structure with a vacuum interlayer, which can greatly provide thermal insulation performance, avoid heat waste, save energy, and be energy-saving and environmentally friendly.

[0034] In some specific embodiments, such as Figure 1 As shown, a plurality of supporting legs 16 are provided at the bottom of the outer drum 1, which can support the entire drying device more stably.

[0035] In some specific implementations, for better control and operation, a conventional control switch or controller may be combined to control the operation of the motor and the on / off of the heating wire.

[0036] Working principle: Figure 1 As shown, when in use, the adsorbent to be dried is first added to the drying chamber 4 through the feed hopper 12. The hot air input device 7 continuously provides hot air, which is directly input into the hot air input chamber 5 through the hot air input pipe 6. Then, the hot air can be evenly distributed from the inside to the outside through the air holes 31 distributed on the surface of the inner cylinder 3, so that the adsorbent put into the drying chamber 4 can be evenly dried. During the drying process, the adsorbent located at the lower part of the drying chamber 4 can enter the vertical pipe 2 through the inlet 21, and can be transported upward to the upper part of the drying chamber 4 by the lifting screw 8, so that the adsorbent has a dynamic cycle and flipping process, realizing the adsorbent circulation drying process, which is not easy to stick to the adsorbent and greatly improves the drying process efficiency. After the drying process is completed, the lifting screw 8 can be driven in reverse by the motor 9 to rotate, so that the adsorbent in the drying chamber that has been dried can be re-entered into the vertical pipe 2 through the inlet 21 and then transported downward. The adsorbent can be discharged outward by opening the baffle 25.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed in this utility model shall be covered by the claims of this utility model.
