Description

Technical Field

[0001] This utility model relates to the field of infrared drying technology, and more specifically, to a vibration-filtering infrared dryer. Background Technology

[0002] Infrared drying technology, as a highly efficient and energy-saving drying method, has been widely used in food processing, chemical, textile, and pharmaceutical industries in recent years. Its core principle is to directly penetrate the surface of materials through infrared radiation, exciting molecular vibrations to generate heat energy, thereby achieving a rapid and uniform drying effect. Compared to traditional hot air drying, infrared technology has advantages such as high thermal efficiency, low energy consumption, and fast heating speed. However, the application of this technology in equipment involving integrated vibration screening and drying still faces significant challenges.

[0003] Existing vibration-filtering infrared drying equipment generally adopts a simple combination of mechanical vibration and infrared radiation. However, in actual operation, the high-frequency vibration of the vibrating screen can easily cause material displacement or accumulation during the conveying process, which in turn causes the infrared radiation focus to shift. In addition, when the vibration is transmitted to the drying module, it may damage the structural stability of the drying chamber, exacerbate the problem of uneven heat field distribution, and ultimately reduce the drying uniformity. On the other hand, the drying method that relies solely on infrared radiation has insufficient penetration for some high-humidity or large-particle materials, resulting in local overheating or incomplete drying. It is necessary to rely on extending the drying time or increasing the radiation intensity to compensate, which leads to increased energy consumption. Therefore, in order to address the above technical problems, a vibration-filtering infrared dryer is proposed here. Utility Model Content

It employs a composite shock absorption structure to isolate vibration interference, combines electronically controlled valve sealing and hot air circulation technology, and utilizes symmetrical funnels to optimize the sorting path. This enables direct sealed drying of materials after grading. The superposition of infrared radiation and hot air penetration enhances heating uniformity, thereby reducing energy consumption while ensuring simultaneous optimization of screening accuracy and drying efficiency.

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.

[0023] Please see Figures 1-5This utility model proposes a vibrating filter infrared dryer, including a vibrating screener 1 and an infrared drying chamber 7. A feeding cylinder 2 is fixedly connected to the upper side of the vibrating screener 1, a screen plate 3 is fixedly connected inside the vibrating screener 1, a bottom plate 4 is fixedly connected to the bottom of the vibrating screener 1, a first hopper 5 and a second hopper 6 are fixedly connected to the bottom of the bottom plate 4, and a vibrating mechanism is installed at the bottom of the bottom plate 4. The infrared drying chamber 7 has a drying chamber 12 and an installation chamber 13 inside. Two sets of symmetrically arranged inner boxes 16 are fixedly connected inside the drying chamber 12. An infrared drying mechanism is installed between the inner boxes 16 and the installation chamber 13. A connecting cylinder 17 is fixedly connected between the inner boxes 16 and one side of the interior of the drying chamber 12. A feeding mechanism is installed on the upper side of the infrared drying chamber 7.

[0024] An inclined surface is provided on the upper side of the base plate 4, and the first hopper 5 and the second hopper 6 are located on the lower side of the inclined surface, so that the screened material can freely roll into the first hopper 5 and the second hopper 6 and enter the infrared drying box 7.

[0025] The first hopper 5 and the second hopper 6 are installed symmetrically around each other.

[0026] A damper 8 and a spring 9 are fixedly connected between the upper side of the infrared drying oven 7 and the bottom of the base plate 4. There are four sets of dampers 8 and springs 9 arranged symmetrically, and the springs 9 are sleeved on the outside of the dampers 8.

[0027] The vibration mechanism includes a fixed frame 10 and a vibration motor 11. The fixed frame 10 is fixedly connected to the bottom of the base plate 4, and the vibration motor 11 is fixedly connected to the outside of the fixed frame 10. The fixed frame 10 facilitates the assembly and disassembly of the vibration motor 11.

[0028] The drying chamber 12 is rotatably connected to the outside of a first cover plate 14, and the installation chamber 13 is rotatably connected to the outside of a second cover plate 15. The infrared drying chamber 7 can be opened or closed by rotating the first cover plate 14 to facilitate the removal of materials from the inner chamber 16. The installation chamber 13 can also be opened by rotating the second cover plate 15 to inspect and maintain the devices in the installation chamber 13.

[0029] The feeding mechanism includes an opening 18, a feeding funnel 19, and an electrically controlled valve 20. The opening 18 is located on the upper side of the connecting cylinder 17. The feeding funnel 19 is fixedly connected to the upper side of the infrared drying chamber 7. There are two sets of feeding funnels 19 arranged symmetrically in a central manner. The two sets of feeding funnels 19 are installed below the first hopper 5 and the second hopper 6. The opening 18 is located below the bottom of the feeding funnel 19. The electrically controlled valve 20 is fixedly connected to the outside of the feeding funnel 19. When the electrically controlled valve 20 is closed, it can improve the sealing of the drying chamber 12 and speed up the drying efficiency. When it is open, it can be used to convey the screened material into the infrared drying chamber 7.

[0030] The infrared drying mechanism includes an infrared radiation plate 21, a hot air blower 22, and a vent 23. The infrared radiation plate 21 is fixedly connected to the top of the inner side of the inner box 16. The hot air blower 22 is fixedly connected to the inside of the installation chamber 13, and the hot air blower 22 is equipped with a fan and heating wire. The vent 23 is opened between the inner box 16 and the installation chamber 13. The vent 23 allows the hot air from the hot air blower 22 to be blown into the inner box 16 to assist in drying.

[0031] The working principle of a vibration-filtering infrared dryer based on an embodiment is as follows: Material first enters the vibrating screen 1 through the feed cylinder 2 and falls onto the surface of the screen plate 3. At this time, the vibration motor 11 drives the base plate 4 and the screen plate 3 to vibrate regularly through the fixed frame 10, causing the material to complete particle size separation on the screen plate 3. The screened material gradually falls through the inclined surface of the base plate 4 into the centrally symmetrically distributed first and second funnels 5 and 6. Subsequently, the material enters the drying chamber 12 inside the infrared drying box 7 through two sets of discharge funnels 19. At this time, the electrically controlled valve 20 is in the open state, and the material passes through the connecting... The material enters the two inner chambers 16 through the channel of cylinder 17 for temporary storage. After the screening operation is completed, the electrically controlled valve 20 automatically closes to ensure that the drying chamber 12 forms a sealed space. At the same time, the infrared radiation plate 21 and the hot air blower 22 start synchronously. The infrared rays released by the infrared radiation plate 21 penetrate the surface of the material to achieve deep heating, while the hot air blower 22 generates hot air through the built-in electric heating wire and introduces it into the inner chamber 16 through the vent 23 to form a hot air circulation system. The synergistic effect of the two significantly improves the drying efficiency and uniformity. After drying, the operator can rotate the first cover plate 14 to open the inner chamber 16 and easily take out the dried material.

[0032] In terms of structural design, the vibrating screen 1 and the infrared drying chamber 7 are connected by four sets of symmetrically distributed dampers 8 and spring components 9. The spring components 9 are sleeved on the outside of the dampers 8 to form a composite shock absorption structure, which effectively isolates the mechanical impact generated by the vibration screening and avoids interference with the stability of the drying process. In addition, the precise alignment design of the opening 18 of the feeding funnel 19 and the connecting cylinder 17, together with the intelligent opening and closing of the electrically controlled valve 20, not only ensures the continuity of material conveying, but also maintains the sealed environment of the drying chamber 12, further enhancing the efficiency of thermal energy utilization. Through multi-structure collaborative control, energy consumption is reduced while the screening accuracy and drying quality are simultaneously optimized.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
