Description
Technical Field
[0001] The utility model relates to the technical field of microwave dryers, in particular to a heating box used for microwave dryers. Background Art
[0002] Microwave dryer is a device that uses microwave technology to dry materials. It uses microwave energy to directly act on medium molecules and convert it into heat energy, thereby achieving rapid drying of materials. The heating box is a key component in the equipment, which is directly related to the drying effect and the operating stability of the equipment.
[0003] However, when the traditional heating box of the microwave dryer is used, the mushrooms themselves contain moisture. During the microwave drying process, the rising water vapor is easy to gather at the dehumidification port, which is prone to dripping for a long time, affecting the drying effect of the mushrooms. For example, in the heating box of the microwave dryer, the conveyed mushrooms will be heated by microwaves. The mushrooms themselves contain moisture, and water vapor will be generated during the drying process. The rising water vapor will gather at the dehumidification port, and multiple accumulations will form water droplets that drip into the interior of the box, affecting the microwave drying process of the mushrooms and resulting in poor drying effect. Utility Model Content

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.
[0016] The heating box for a microwave dryer disclosed by the utility model is mainly used in scenarios where, when a conventional heating box for a microwave dryer is used, the mushrooms themselves contain moisture, and during the microwave drying process, the rising water vapor tends to gather at the moisture drain port, which is prone to dripping water for a long time, affecting the drying effect of the mushrooms.
[0017] Reference Figure 1 、 Figure 2 and Figure 3 The heating box body for the microwave dryer includes a reversing end frame 1 and a power end frame 2. A bridge body 3 and a conveyor belt 4 are provided between the reversing end frame 1 and the power end frame 2. Several heating box bodies 5 are provided on the bridge body 3. The conveyor belt 4 is located inside the several heating box bodies 5. A top cover 7 is provided on the top outer wall of the heating box body 5. The top outer wall of the top cover 7 and the bottom outer wall of the heating box body 5 are both provided with a moisture drainage port 9. A funnel 14 is provided on the top inner wall of the top cover 7. The outer wall of the funnel 14 is provided with leakage holes 15 distributed at equal distances. Support rods 12 are provided on the inner walls around the top cover 7. The opposite ends of the four support rods 12 are fixedly connected to the same collecting bucket 13.
[0018] During the specific working process, the reversing end frame 1 and the power end frame 2 are used to support the installation of the bridge body 3 and multiple heating box bodies 5 on the bridge body 3. The conveyor belt 4 is located inside the heating box body 5 to transport the mushrooms, and then the mushrooms are microwave-dried inside the heating box body 5. When the water vapor rises during the heating process and gathers at the dehumidification port 9 on the top cover 7, the water droplets formed for a long time fall into the funnel 14 and drip into the collecting bucket 13 through the leak hole 15 for collection. The gas inside the heating box body 5 can be transmitted between the support rod 12 and the funnel 14 and dehumidified and exhausted through the dehumidification port 9. While dissipating heat, the formed water droplets can also be collected.
[0019] It should be noted that the device is installed with eight heating box bodies 5, and different usage scenarios require different numbers of heating box bodies 5 to be installed, depending on the actual usage.
[0020] Among them, the funnel 14, the dehumidification port 9 on the top cover 7 and the collecting bucket 13 are located in the same direction. In this way, the water droplets collected at the dehumidification port 9 on the top cover 7 drip in a straight line and can all fall into the collecting bucket 13 for collection. The collecting bucket 13 fully covers the funnel 14, so that the water droplets in the funnel 14 leak into the collecting bucket 13 through the leakage hole 15, and the water droplets will not fall into the heating box body 5 and affect the drying effect of the mushrooms.
[0021] Reference Figure 3 In a preferred embodiment, a conduit 16 is connected to the outer wall of one side of the collecting bucket 13, and the conduit 16 is connected to the collecting bucket 13. A control valve 17 is provided on one side of the circumferential outer wall of the conduit 16, and the control valve 17 is used in conjunction with the conduit 16.
[0022] Specifically, the conduit 16 is connected to the collecting hopper 13, and the water droplets are discharged from the inside of the heating box body 5 to the outside of the heating box body 5. The water droplets collected in the collecting hopper 13 are discharged to the outside of the heating box body 5 by the conduit 16. The control valve 17 is used to open and close the conduit 16 so that the water droplets are discharged in an orderly manner. The switch can be controlled and the discharge is convenient.
[0023] Reference Figure 2 and Figure 3 In a preferred embodiment, a dehumidification duct 8 is provided on one side outer wall of the heating box body 5, and connecting channels 11 are provided on both sides of the outer walls of the heating box body 5. A sensor is provided on the inner wall of the connecting channel 11, and the sensor is used in conjunction with the connecting channel 11.
[0024] Specifically, the dehumidification duct 8 and the dehumidification port 9 form an exhaust system, which can discharge the heat generated during the microwave drying process to achieve a heat dissipation effect. The connecting channels 11 on both sides of the heating box body 5 can feed and discharge shiitake mushrooms. The sensor is used to control the opening and closing of the connecting channel 11. When opened, shiitake mushrooms can be fed and discharged. When closed, the wave source will not leak during the microwave drying process.
[0025] Reference Figure 1 、 Figure 2 and Figure 3 In a preferred embodiment, a furnace door 6 is connected to the inner wall of the heating box body 5 close to the dehumidification air duct 8 through a hinge, a sealing ring 18 is provided on the inner wall of the furnace door 6, and a handle 10 is fixedly connected to the outer wall of one side of the furnace door 6. The furnace door 6 is provided with a microwave leakage prevention choke device and a travel switch.
[0026] Specifically, the oven door 6 is opened by the handle 10 to observe the changes in the mushrooms in the heating box body 5. The sealing ring 18 is used to seal and clamp the oven door 6 when it is closed, which is safer. The oven door 6 adopts a precise anti-microwave leakage choke device and is equipped with a travel switch. It has an automatic power-off protection function when the door is opened, and can also prevent microwave leakage. A lighting lamp is also installed on the top of the heating box body 5 (not shown in the figure), which makes it more convenient to observe the mushrooms in the heating box body 5.
[0027] Working principle: When in use, the mushrooms are transported on the conveyor belt 4 and fed into the heating box body 5 through the connecting channel 11 on one side for microwave drying. When the water vapor rises during the heating process and gathers at the dehumidification port 9 on the top cover 7, the water droplets formed over a long period of time fall into the funnel 14 and drip into the collecting bucket 13 through the leak hole 15 for collection. The water droplets collected in the collecting bucket 13 are guided out of the heating box body 5 by the conduit 16. The control valve 17 is used to open and close the conduit 16. The dehumidification duct 8 and the dehumidification port 9 form an exhaust system, which can discharge the heat generated during the microwave drying process to achieve a heat dissipation effect. The oven door 6 is opened by the handle 10 to observe the changes of the mushrooms in the heating box body 5. The sealing ring 18 seals and clamps the oven door 6. The anti-microwave leakage choke device and the travel switch on the oven door 6 have an automatic power-off protection function when the door is opened, which can also prevent microwave leakage. After drying, the mushrooms are discharged and transported through the connecting channel 11 on the other side of the heating box body 5.
