[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 4This utility model provides an embodiment of a dual-exhaust-draft energy-saving dryer, comprising a dryer body 1, an exhaust gas discharge component 2, and an exhaust gas filter component 3. The exhaust gas discharge component 2 and the exhaust gas filter component 3 are located at the top of the dryer body 1 and are connected by a quick-release component 4, allowing the exhaust gas filter component 3 to be quickly installed and removed, facilitating later maintenance and replacement of filter elements. The dryer body 1 has a drying drum 11 inside for drying materials. The drying drum 11 works in conjunction with the bidirectional exhaust system to achieve efficient circulation of hot air and timely discharge of moisture, improving drying efficiency. A sealing door 12 is rotatably connected to the front of the dryer body 1, ensuring that heat and moisture do not leak out during the drying process and facilitating loading and unloading of materials. A control panel 13 is located on the upper front of the dryer body 1, which can precisely adjust and monitor the drying temperature, time, and operating status of the dual exhaust system in real time. The exhaust gas filtration assembly 3 includes a housing 31 and an activated carbon filter cartridge 32 located inside the housing 31. The activated carbon filter cartridge 32 is used to adsorb dust, odors, and volatile organic compounds (VOCs) in the exhaust gas, thereby achieving efficient purification of the exhaust gas. Simultaneously, the housing 31 protects the stable operation of the filter cartridge and facilitates replacement and cleaning by operators. Through this structural design, this invention not only improves drying efficiency and exhaust gas treatment effect but also significantly enhances the ease of use and environmental friendliness of the equipment.

[0034] Reference Figure 1 - Figure 3 The exhaust gas discharge assembly 2 includes an exhaust gas discharge pipe 21 and an exhaust gas collection hood 22. The bottom of the exhaust gas discharge pipe 21 is fixedly connected to the exhaust gas outlet on the top wall of the dryer body 1, serving to guide the flow and discharge of exhaust gas. A fixing hole 211 for fixing the structure is provided on the side wall of the exhaust gas discharge pipe 21, and two limiting grooves 212 are symmetrically arranged on its inner wall. The limiting grooves 212 are designed to limit the sliding direction of the sliders 221, ensuring structural stability. Two sliders 221 are symmetrically installed on the outer side of the exhaust gas collection hood 22. The sliders 221 are slidably connected in the limiting grooves 212 on the inner wall of the exhaust gas discharge pipe 21, thereby achieving stable sliding installation of the exhaust gas collection hood 22. A fixing hole 222 is provided on the side wall of the exhaust gas collection hood 22. The fixing hole 222 cooperates with the fixing hole 211 of the exhaust gas discharge pipe 21, allowing the two to be connected by a pin 42. The pin 42 can be slidably installed inside the fixing hole 211 and the fixing hole 222 to quickly fix and remove the exhaust gas collection cover 22. In addition, a retaining box 41 is fixedly installed on the outside of the exhaust gas discharge pipe 21. Through this structural design, the exhaust gas discharge assembly 2 not only ensures smooth exhaust gas discharge but also, through the combination of sliding and quick-release design, enables rapid installation and removal of the exhaust gas collection cover 22, greatly improving the convenience of equipment maintenance and operational efficiency.

[0035] ReferenceFigure 4 The quick-release assembly 4 includes a cartridge 41, with a pin 42 slidably connected inside the cartridge 41. The pin 42 connects the exhaust gas discharge assembly 2 and the exhaust gas filter assembly 3, achieving a stable connection between the components. A spring 43 is sleeved on the outside of the pin 42, providing an elastic reset function when the pin 42 slides, thus ensuring that the pin 42 can quickly reset and remain secure. A limiting plate 44 is fixedly connected to the middle of the pin 42, controlling the sliding range of the pin 42 and providing stability and fixation. One end of the spring 43 is fixedly connected to the outside of the limiting plate 44, and the other end abuts against the inner wall of the cartridge 41. The tension of the spring 43 keeps the limiting plate 44 and the pin 42 in a preset position to ensure the reliability of the quick-release assembly 4 during use.

[0036] Furthermore, an L-shaped control rod 45 is slidably connected to the top wall of the card box 41, with the bottom of the L-shaped control rod 45 abutting against the top wall of the limiting plate 44. When it is necessary to disassemble the exhaust gas discharge assembly 2 and the exhaust gas filter assembly 3, the pin 42 is pulled outward. The L-shaped control rod 45 loses its bottom support and slides down, locking into the end of the pin 42. At this time, the operator does not need to hold the pin 42 continuously, freeing their hands to replace the exhaust gas filter assembly 3, simplifying the installation and maintenance process. In addition, the closed structure of the card box 41 can effectively protect internal parts such as the pin 42, spring 43, and limiting plate 44, preventing the entry of dust or impurities, further improving the service life and operational reliability of the quick-release assembly 4.

[0037] Working Principle: Hot air is evenly introduced into the drying drum 11 inside the dryer body 1 via a primary induced draft system, ensuring full contact between the hot air and the material for rapid evaporation of moisture. Simultaneously, a secondary induced draft system guides moisture and exhaust gas from the exhaust outlet on the top wall of the dryer body 1 to the exhaust gas discharge assembly 2. The exhaust gas discharge assembly 2 collects the exhaust gas through the exhaust pipe 21 and uses the exhaust gas collection hood 22 to centrally guide the exhaust gas to the exhaust gas filter assembly 3. The exhaust gas filter assembly 3 consists of an outer shell 31 and an internal activated carbon filter cartridge 32. The activated carbon filter cartridge 32 efficiently adsorbs and purifies dust, volatile organic compounds (VOCs), and odors in the exhaust gas, ensuring that the emitted exhaust gas meets environmental protection requirements. Furthermore, the exhaust gas discharge assembly 2 and the exhaust gas filter assembly 3 are connected by a quick-release assembly 4. This quick-release assembly 4, through the coordinated operation of a retaining box 41, a pin 42, a spring 43, a limiting plate 44, and an L-shaped control rod 45, enables the rapid installation and removal of the exhaust gas filter assembly 3, facilitating the maintenance and replacement of the activated carbon filter cartridge 32. Through this multi-module collaborative operation, the equipment achieves efficient and uniform drying of materials, environmentally friendly exhaust gas emissions, and convenient maintenance, thus improving overall drying efficiency and practicality.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
