[0020] This utility model embodiment provides an energy-saving and carbon-reducing waste steam drying device, such as... Figures 1-3 As shown, the energy-saving and carbon-reducing waste steam drying device includes: a drying chamber 1; a heat exchanger 2, which is connected to the drying chamber 1 via a hot air pipe 3; a recovery pipe 4, which is fixedly installed on the heat exchanger 2 for recovering hot air containing water vapor, and the other end of the recovery pipe 4 extends into the drying chamber 1; a holding trough 5, which is fixedly installed in the drying chamber 1 for placing materials to be dried, and is positioned above the hot air pipe 3; a sliding chute 6, which is formed on the inner walls of both sides of the holding trough 5; a sliding plate 7, which is slidably installed between the sliding chute 6 within the holding trough 5; a toothed rake 8, which is fixedly installed at the bottom of the sliding plate 7, and the bottom of the toothed rake 8 slides in contact with the bottom inner wall of the holding trough 5; and a reciprocating mechanism, which is provided on the drying chamber 1 for driving the sliding plate 7 and the toothed rake 8 to reciprocate and disperse the materials.

[0021] In this embodiment, the drying box 1 serves as the main container for the entire drying process, providing a closed environment for the circulation of hot air to dry the materials, ensuring the stability and controllability of the drying process. The heat exchanger 2 is used to recover the waste heat in the hot air discharged during the drying process and convert it back into hot air to be fed into the drying box 1 again, significantly improving the efficiency of heat energy utilization and reducing energy consumption, in line with the goal of energy saving and carbon reduction. The recovery pipe 4 is used to recover the hot air containing water vapor, achieving the recycling of hot air and reducing heat waste. The holding tank 5 is used to place the materials to be dried and is located above the hot air pipe 3, ensuring that the hot air can fully contact and dry the materials, providing a stable platform for material placement and facilitating the drying of the materials. By sliding the sliding plate 7, the position and distribution of the materials can be continuously changed, avoiding the problem of incomplete drying of the contact surface between the materials and the bottom or other materials, and improving the drying efficiency. The tooth rake 8 is used to further disperse and turn the materials. The design of the tooth rake 8 increases the contact area between the materials and the hot air, promoting heat transfer and accelerating the drying process. The reciprocating mechanism is used to drive the sliding plate 7 and the tooth rake 8 to move back and forth, thereby continuously dispersing and turning the materials. The presence of the reciprocating mechanism realizes dynamic drying of the materials, avoiding the problem of material accumulation and uneven drying during the drying process, further improving the drying efficiency and quality.

[0022] In further preferred embodiments of the present application, the reciprocating mechanism comprises a drive motor 9, a turntable 10, an eccentric shaft 11 and a connecting rod 12. The drive motor 9 is fixedly installed on the drying box 1, and the output shaft of the drive motor 9 extends into the drying box 1 and is fixedly connected with the turntable 10. The eccentric shaft 11 is fixedly installed on the turntable 10, and the connecting rod 12 is hingedly connected between the eccentric shaft 11 and the sliding plate 7.

[0023] In this embodiment, the drive motor 9 serves as the power source of the reciprocating mechanism, providing stable and controllable power output to ensure the normal operation of the reciprocating mechanism. After the drive motor 9 is started, its output shaft begins to rotate, driving the turntable 10 fixedly connected therewith to rotate. The rotational motion of the turntable 10 drives the eccentric shaft 11 to move in a circular motion, providing a basis for the reciprocating motion of the connecting rod 12. The rotation of the eccentric shaft 11 causes the hinged point between the connecting rod 12 to change position continuously, thereby driving the connecting rod 12 to move back and forth. Through the eccentric design, the function of converting rotational motion into reciprocating motion is realized, providing power for the reciprocating dispersion of the sliding plate 7 and the tooth rake 8. The hinged design of the connecting rod 12 enables it to adapt to the circular motion of the eccentric shaft 11 and convert it into the reciprocating motion of the sliding plate 7 and the tooth rake 8, realizing dynamic drying of the materials.

[0024] The further preferred embodiment of the utility model discloses, the top fixed mounting of drying box 1 has dustproof screen 13, dustproof screen 13 cover is established in the part pipeline outside of recycling pipe 4 extension to drying box 1.

At the same time, it also prevents the fine particulate matter generated during the drying process from flowing back to the outside through the recycling pipe 4. The dustproof screen 13 effectively blocks the entry of external dust and impurities, maintaining the cleanliness of the interior of the drying box 1, thereby avoiding the influence of these pollutants on the drying effect and material quality. The presence of the dustproof screen 13 reduces the heat loss and uneven drying caused by dust and other impurities during the drying process, ensuring that the hot air can more effectively transfer heat to the material, improving the drying efficiency. The dustproof screen 13 also prevents fine particulate matter from entering critical components such as the heat exchanger 2 through the recycling pipe 4, reducing equipment failures caused by blockage or wear, and prolonging the service life of the drying device.

[0026] In the further preferred embodiment of the utility model, a sealing door 14 is hingedly connected to the side wall of the drying box 1, and the sealing door 14 is correspondingly arranged with the holding tank 5. A handle is fixedly installed on the sealing door 14.

[0027] In the embodiment, the sealing door 14 can rotate around its hinge point, thereby opening or closing the side wall of the drying box 1, allowing users to conveniently access and operate the holding tank 5. When it is necessary to put in or take out the material, the user can open the sealing door 14; when the drying process is in progress, the sealing door 14 remains closed to ensure the sealing and heat retention of the interior of the drying box 1. The design of the sealing door 14 ensures the sealing of the drying box 1 during the drying process, preventing heat loss and the entry of external air, thereby improving the drying efficiency and quality. The sealing door 14 is correspondingly arranged with the holding tank 5, allowing users to easily put in or take out the material without the need to disassemble or move other components of the drying box 1, improving the convenience and efficiency of the operation. The closed state of the sealing door 14 can prevent high temperature and steam generated during the drying process from causing harm to the operator, enhancing the safety of the equipment. The handle design allows users to easily open or close the sealing door 14 without the need for additional tools or effort, improving the convenience and efficiency of the operation.

[0028] In the further preferred embodiment of the utility model, a hydraulic rod 15 is fixedly installed on the top of the drying box 1. An output rod of the hydraulic rod 15 is fixedly installed with a sealing plate 16. The other end of the sealing plate 16 extends into the drying box 1 and is sealingly and slidingly connected with the sealing door 14. The sealing plate 16 is sealingly and slidingly connected with the inner wall of the holding tank 5.

[0029] In this embodiment, the hydraulic rod 15 drives the sealing plate 16 fixed thereon to move up and down through the telescopic movement of its output rod. When it is necessary to open or close the holding tank 5, the hydraulic rod 15 will be elongated or shortened accordingly, thereby pushing the sealing plate 16 to slide. The introduction of the hydraulic rod 15 realizes the automatic control of the sealing plate 16, reduces the tediousness and errors of manual operation, and improves the automation degree and operation efficiency of the equipment. The precise control of the hydraulic rod 15 enables the sealing plate 16 to be tightly and sealingly connected with the inner wall of the sealing door 14 and the holding tank 5, thereby ensuring the sealing property of the drying box 1 during the drying process and preventing the loss of heat and the entry of external air. The introduction of the sealing plate 16 not only improves the sealing property of the equipment, but also enhances the overall stability of the equipment, making the drying process more stable and safe.

[0030] In further preferable embodiments of the present application, a limiting groove 17 is formed in the side wall of the drying box 1, and a limiting block 18 is fixedly installed on the sealing plate 16 and slidably connected with the limiting groove 17.

[0031] In this embodiment, the limiting groove 17 provides a fixed sliding track, so that the limiting block 18 can stably slide therein. When the sealing plate 16 moves up and down along with the output rod of the hydraulic rod 15, the limiting block 18 fixed thereon will slide along the limiting groove 17, thereby ensuring the movement path and stability of the sealing plate 16. The sliding connection design of the limiting groove 17 and the limiting block 18 enhances the stability of the sealing plate 16 during movement, prevents it from deviating or shaking due to external force or internal stress, and thereby ensures the sealing property and drying efficiency of the drying box 1. The limiting groove 17 provides an accurate sliding path for the limiting block 18, so that the sealing plate 16 can accurately reach the specified position and form a tight seal with the inner wall of the sealing door 14 and the holding tank 5, thereby improving the sealing performance and drying quality of the equipment. The limiting block 18 also prevents the sealing plate 16 from moving excessively or deviating from the track, thereby improving the sealing performance and drying efficiency of the equipment.

[0032] In further preferable embodiments of the present application, an air inlet 19 is formed in the drying box 1 opposite to the sealing door 14, a fan 20 is fixedly installed on the drying box 1, a guide pipe 21 is fixedly installed at the output end of the fan 20, and the other end of the guide pipe 21 is fixedly connected with the air inlet 19.

[0033] In this embodiment, after the drying process is completed, some fine impurities such as material debris, dust, etc. may remain inside the drying cabinet 1. At this time, the fan 20 can be controlled to operate, and external air is blown into the inside of the drying cabinet 1 through the guide pipe 21 and the air inlet 19. The force of this airflow can blow off the impurities attached to the inner wall of the holding tank 5 and other parts of the drying cabinet 1, thereby playing a cleaning role. In addition, the fresh air introduced through the air inlet 19 can also replace the harmful gases or vapors that may be generated inside the drying cabinet 1 during the drying process, keeping the air inside the drying cabinet 1 fresh and hygienic. By using the design of the fan 20 and the air inlet 19, the impurities can be blown off by the force of the airflow without disassembling the drying cabinet 1 or the holding tank 5, thereby simplifying the cleaning process of the equipment. Regularly introducing fresh air through the air inlet 19 and blowing off impurities helps to keep the inside of the drying cabinet 1 clean and hygienic, reducing equipment failure or pollution problems caused by the accumulation of impurities. By reducing the accumulation of impurities inside the drying cabinet 1, the wear and corrosion of the equipment parts can also be reduced, thereby prolonging the service life of the equipment.

[0034] In summary, compared with related technologies, the disclosed device recovers and utilizes the waste heat in the waste steam through a heat exchanger, and converts it into hot air for reuse in the drying process, significantly improving the heat energy utilization efficiency and reducing energy consumption. By driving the sliding plate and the rake to move back and forth through the reciprocating mechanism, the material is constantly dispersed and turned over, avoiding the problem of incomplete drying of the contact surface between the material and the bottom or between the material and other materials, and improving the drying efficiency and drying quality. The design of the hydraulic rod and the sealing plate realizes the automatic control of the holding tank, reduces the tediousness and errors of manual operation, and improves the automation degree and operation efficiency of the equipment. At the same time, the design of the sealing door and the handle also facilitates the putting in and taking out of the material. The design of the dust screen and the air inlet simplifies the cleaning process of the equipment, and regularly blowing off impurities by introducing fresh air through the fan helps to keep the inside of the drying cabinet clean and hygienic, reducing equipment failure or pollution problems caused by the accumulation of impurities.
