[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figures 1-5 This utility model provides a drying device for leather waste after steaming, including a box body 1. Multiple support columns 2 are fixedly connected to the bottom of the box body 1. A first concave frame 3 and a second concave frame 4 are fixedly connected to the bottom of the box body 1. A fan 5 is fixedly connected to the upper bottom surface of the first concave frame 3. A heating box 6 is fixedly connected to the upper bottom surface of the second concave frame 4. A first air duct 7 is fixedly connected between the fan 5 and the heating box 6. A second air duct 8 is fixedly connected to one side of the heating box 6. A ventilation box 9 is fixedly connected to the bottom of the box body 1 through the top of the second air duct 8. Multiple evenly distributed drying column heads 10 are fixedly connected to the top of the ventilation box 9. Connecting plates 11 are fixedly connected to the front and rear ends of the ventilation box 9. Two support rollers 12 are rotatably connected between the inner walls on both sides of the box body 1. A filter frame 13 is overlapped on the top of the two support rollers 12. A baffle 14 is fixedly connected to the front end of the filter frame 13. A handle 15 is fixedly connected to the front end of the baffle 14. A purification mechanism 16 is provided on the top of the box body 1.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that multiple support columns 2 are all fixedly connected to their bottoms with shock-absorbing sleeves. These sleeves effectively absorb and reduce vibrations generated during equipment operation. This prevents vibrations from being transmitted to the ground or other structures, thereby reducing noise and vibration pollution caused by vibration. During operation, the equipment may generate significant noise due to mechanical friction, running, etc. The shock-absorbing sleeves effectively slow down the propagation of vibration waves, reducing the impact of noise on operators and the surrounding environment. The reduced vibration from the shock-absorbing sleeves ensures a more stable heating process in the drying device, contributing to the uniformity and efficiency of the drying effect, and avoiding temperature fluctuations or uneven drying caused by vibration.

[0025] Further as Figure 3 As shown, it is worth noting that the second air duct 8, the ventilation box 9, and the drying column head 10 are internally connected. Under the action of the second air duct 8, hot air enters the ventilation box 9 and is then discharged by multiple drying columns 10, acting evenly on the surface of the leather waste, making the surface of the leather waste more evenly heated and improving the drying effect.

[0026] Further as Figure 3 As shown, it is worth noting that the two connecting plates 11 are fixedly connected to the inner walls of the front and rear ends of the box 1, respectively. The two connecting plates 11 play a role in fixing the ventilation box 9, so that the ventilation box 9 is stably installed inside the box 1.

[0027] Further as Figure 4 As shown, it is worth noting that a sealing gasket is fixedly connected to the rear end of the baffle 14. The sealing gasket seals the chamber 1, preventing the heating gas during the drying process from escaping from the opening in the chamber 1 at the rear end of the baffle 14.

[0028] As can be seen from the above working process: by setting up the fan 5 and the heating box 6 in combination, the air blown out by the fan 5 is turned into hot air by the heating box 6, and enters the ventilation box 9 under the action of the second air duct 8. Then, it is discharged by multiple drying columns 10 and evenly applied to the surface of the leather waste, so that the surface of the leather waste is heated more evenly and the drying effect is improved.

[0029] Further as Figure 5As shown, it is worth noting that the purification mechanism 16 includes an air outlet 1601 fixedly connected to the top of the housing 1. An air supply pipe 1602 is fixedly connected to the top of the air outlet 1601. A purification chamber 1603 is fixedly connected to the rear end of the air supply pipe 1602. An activated carbon adsorption plate 1604 is slidably connected to the top of the purification chamber 1603. An exhaust pipe 1605 is fixedly connected to the rear end of the purification chamber 1603. By setting up the purification mechanism 16, the gas generated during the drying process is discharged from the air outlet 1601, enters the purification chamber 1603 through the air supply pipe 1602, is filtered by the activated carbon adsorption plate 1604, and is then discharged to the external environment through the exhaust pipe 1605. This effectively adsorbs and removes harmful substances from the gas, purifies the working environment, and protects the health of the staff.

[0030] Further as Figure 5 As shown, it is worth noting that the purification chamber 1603 has a limiting groove inside that corresponds to the activated carbon adsorption plate 1604. The limiting groove can fix the activated carbon adsorption plate 1604 in a predetermined position, preventing the adsorption plate from shifting or loosening due to vibration or airflow during the drying process, thereby ensuring the stable and continuous adsorption effect of the activated carbon. Through the limiting groove, the activated carbon adsorption plate 1604 can easily slide into or out of the purification chamber 1603, facilitating regular replacement, cleaning, or maintenance, reducing operational complexity, and improving work efficiency. The precise positioning of the activated carbon adsorption plate 1604 through the limiting groove ensures sufficient contact between the adsorption plate and the airflow, thereby improving adsorption efficiency.

[0031] The working process of this solution is as follows: In actual use, the leather waste to be dried is placed on top of the filter frame 13, and then the filter frame 13 is pushed into the box 1. The fan 5 and the heating box 6 are turned on. The air blown out by the fan 5 is turned into hot air by the heating box 6. Under the action of the second air duct 8, it enters the ventilation box 9 and is then discharged by multiple drying columns 10 to evenly act on the surface of the leather waste. The gas generated during the drying process is discharged from the air outlet 1601, enters the purification box 1603 through the air supply pipe 1602, is filtered by the activated carbon adsorption plate 1604, and is then discharged into the external environment through the exhaust pipe 1605.

[0032] In summary: By coordinating the fan 5 and the heating box 6, the air blown by the fan 5 is transformed into hot air by the heating box 6. Under the action of the second air duct 8, it enters the ventilation box 9 and is then discharged by multiple drying columns 10, evenly acting on the surface of the leather waste. This makes the surface of the leather waste more evenly heated and improves the drying effect. By setting up the purification mechanism 16, the gas generated during the drying process is discharged from the air outlet 1601, enters the purification box 1603 through the air supply pipe 1602, is filtered by the activated carbon adsorption plate 1604, and is then discharged into the external environment through the exhaust pipe 1605. This effectively adsorbs and removes harmful substances in the gas, purifies the working environment, and protects the health of the workers.
