[0026] 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.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A material turning auxiliary device for solar drying of recycled materials includes a solar collector plate body 1, a heat collection mechanism 2 welded to the bottom of the solar collector plate body 1, and a turning mechanism 3 rotatably connected to the inner side of the heat collection mechanism 2. The turning mechanism 3 includes a placement shell 31, a rotating rod 32, a fixing ring, a connecting rod 34, a servo motor 35, a limiting rod 36, a snap-fit ​​filter plate 37, an electro-adsorption magnet 38, and a sliding hole 39. The placement shell 31 is rotatably connected to the inner side of the heat collection mechanism 2. The rotating rod 32 is welded to the left side of the placement shell 31. The left side of the rotating rod 32 is rotatably connected to the inner wall of the left side of the heat collection mechanism 2. The fixing ring is installed on the right side of the placement shell 31. The connecting rod 34 is fixedly connected to the inner side of the fixing ring. The servo motor 35 is installed on the right side of the heat collection mechanism 2. The right side of the connecting rod 34 is connected to a connecting shaft via a flat key.

[0029] In this embodiment: the solar collector panel 1 directly absorbs solar radiation and converts it into heat energy. The placement shell 31 can hold materials, and the mesh-like bottom design facilitates hot air penetration through the material layer. The rotating rod 32 provides a stable left fulcrum for the placement shell 31, which, together with the right fixing ring, enables the smooth rotation of the placement shell 31. The fixing ring connects the placement shell 31 to the connecting rod 34, transmitting the power of the servo motor 35 to the placement shell 31, thus achieving controllable rotation of the placement shell 31. The connecting rod 34 transmits the rotational power to the placement shell 31 through a connecting shaft. The speed and rotation angle are controlled by the PLC controller 4. The turning frequency can be flexibly adjusted according to the hot air temperature and material humidity. The sliding fit between the limit rod 36 and the sliding hole 39 restricts the movement direction of the snap-fit ​​filter plate 37, ensuring that the snap-fit ​​filter plate 37 will not shift during installation, disassembly and turning. After the snap-fit ​​filter plate 37 is connected to the placement shell 31, it can prevent the material from falling when the placement shell 31 rotates. The electro-adsorption magnet 38 realizes the quick fixation and separation of the snap-fit ​​filter plate 37 and the placement shell 31 through magnetic adsorption. The sliding hole 39 ensures smooth sliding fit with the limit rod 36.

[0030] Specifically, such as Figure 3 , Figure 4 As shown, the output end of the servo motor 35 on the left side passes through the heat collection mechanism 2 and is fixedly connected to the right side of the connecting shaft. The limiting rod 36 is welded to both sides of the bottom of the inner side of the placement shell 31. The snap-fit ​​filter plate 37 is movably connected to the inner side of the placement shell 31. The electro-adsorption magnet 38 is welded to both sides of the top of the snap-fit ​​filter plate 37. The sliding holes 39 are respectively opened on both sides of the inner side of the snap-fit ​​filter plate 37 and the inner side of the electro-adsorption magnet 38. The sliding holes 39 are slidably connected to the surface of the limiting rod 36.

[0031] Specifically, such as Figure 5 , Figure 6 As shown, the solar collector 2 includes a heat-conducting plate 21, an insulation box 22, an air duct 23, an exhaust fan 24, two guide plates 25, a ventilation pipe 26, a drying box 27, a cover plate 28, and three exhaust ports 29. The heat-conducting plate 21 is welded to the bottom of the solar collector body 1.

[0032] Specifically, such as Figure 5 , Figure 6 As shown, the heat preservation box 22 is welded to the bottom of the solar collector plate body 1, the placement shell 31 is rotatably connected to the inside of the heat preservation box 22, the left side of the rotating rod 32 is rotatably connected to the inner wall of the left side of the heat preservation box 22, the servo motor 35 is installed on the right side of the heat preservation box 22, and the output end of the left side of the servo motor 35 passes through the heat preservation box 22 and is fixedly connected to the right side of the connecting shaft.

[0033] In this embodiment: by setting the heat-conducting plate 21 to be made of a high thermal conductivity material such as aluminum alloy or copper alloy, it can quickly receive the heat energy absorbed by the solar collector plate body 1. The heat preservation box 22 can effectively block the internal heat energy from dissipating to the outside, so that the temperature inside the box can be maintained stably. The air duct 23 can support and limit the suction fan 24. The suction fan 24 can quickly convert the heat energy inside the heat preservation box 22 into directional hot air. The wind speed can be adjusted by the PLC controller 4. The guide plate 25 guides the hot air delivered by the suction fan 24 to the ventilation pipe 26 below the heat preservation box 22. The ventilation pipe 26 can guide the hot air inside the heat preservation box 22 to the inside of the drying box 27. The drying box 27 provides an independent closed environment for the material, and can also support and limit the turning mechanism 3. The cover plate 28 makes it convenient for users to load and unload materials. The exhaust port 29 can timely discharge the moisture evaporated during the material drying process.

[0034] Specifically, such as Figure 5 , Figure 6 As shown, the exhaust duct 23 is fixedly connected to the top of the inner side of the insulation box 22, the suction fan 24 is installed inside the exhaust duct 23, the guide plate 25 is welded to the inner side of the insulation box 22, the ventilation duct 26 is fixedly connected to the bottom of the right side of the insulation box 22, the drying box 27 is fixedly connected to the right side of the ventilation duct 26, the cover plate 28 is rotatably connected to the top of the drying box 27, and the exhaust port 29 is opened inside the cover plate 28.

[0035] Specifically, such as Figure 2 , Figure 5 As shown, a PLC controller 4 is installed on the front side of the insulation box 22, and a temperature sensor 5 is installed on the top of the ventilation pipe 26. The PLC controller 4 is electrically connected to the temperature sensor 5, the suction fan 24, the servo motor 35, and the electro-adsorption magnet 38.

[0036] In this embodiment: by setting up a PLC controller 4, and electrically connecting and integrating a temperature sensor 5, a suction fan 24, a servo motor 35, and an electro-adsorption magnet 38, the entire process of temperature monitoring, hot air adjustment, material turning, and filter plate fixing is fully automated. By setting up a temperature sensor 5, it can directly contact the hot air and capture hot air temperature fluctuations in real time, ensuring that the drying temperature is always within the material's suitable range.

[0037] Specifically, such as Figure 1 As shown, a dust filter 6 is movably connected to the inner side of the exhaust vent 29, and the surface of the dust filter 6 is coated with an anti-corrosion coating.

[0038] Specifically, such as Figure 3 As shown, a ventilation filter plate 7 is snapped into the bottom of the inner side of the drying oven 27, and the surface of the ventilation filter plate 7 is coated with an anti-corrosion coating.

[0039] In this embodiment: by setting a dust filter 6, external dust and insects can be blocked from entering the drying chamber 27 through the exhaust port 29, avoiding material contamination and ensuring that the finished product meets hygiene standards. By setting an anti-corrosion coating, it can resist the erosion of moisture and impurities in a humid and hot environment, preventing the filter from rusting or becoming moldy and extending its service life. By setting a ventilation filter plate 7, it can filter dust, sand and other impurities in the air. By setting an anti-corrosion coating, it is adapted to the humid and hot environment inside the drying chamber 27 and is not easy to rust or deform.

[0040] Specifically, such as Figure 3 As shown, the bottom of the housing 31 and the inner side of the snap-fit ​​filter plate 37 are both made of filter mesh, and the surfaces of the housing 31 and the snap-fit ​​filter plate 37 are coated with anti-corrosion paint.

[0041] Specifically, such as Figure 4 As shown, a heat insulation sleeve 8 is fitted on the surface of the electro-adsorption magnet 38. The heat insulation sleeve 8 is made of silicone material and has several heat dissipation holes on its surface.

[0042] In this embodiment: by setting the bottom of the housing 31 and the inner side of the snap-fit ​​filter plate 37 to be filter mesh, hot air can penetrate the material layer from the bottom, increasing the contact area between the material and the hot air. By setting an anti-corrosion coating, it can resist the corrosion of acidic and alkaline components in the material and the humid and hot environment, and prevent the parts from rusting and deforming. By setting a heat insulation sleeve 8, the silicone material has excellent heat insulation performance. When it is set on the surface of the electro-adsorption magnet 38, it can block the high temperature in the drying environment from being transmitted to the inside of the magnet, and prevent the magnet from weakening or permanently failing due to high temperature. By setting the heat insulation sleeve 8 to be made of silicone material, the silicone material is soft and elastic and can fit tightly to the surface shape of the electro-adsorption magnet 38, and prevent heat insulation failure caused by gaps. By setting heat dissipation holes, the heat generated by the electro-adsorption magnet 38 during operation can be discharged in time, and the magnet can be prevented from heating up due to its own heat generation, further ensuring magnetic stability.

[0043] Working principle: First, the solar collector panel 1 directly absorbs external solar radiation energy and converts it into heat energy. Simultaneously, the operator opens the top cover 28 of the drying chamber 27 and loads the material to be dried into the bottom of the placement shell 31. Then, the operator slides the snap-fit ​​filter plate 37 through the sliding hole 39 and the limiting rod 36 to adjust it to a height suitable for the material thickness. Next, the electromagnet 38 magnetically attaches the snap-fit ​​filter plate 37 to the placement shell 31 to prevent the material from falling off during subsequent turning. Finally, the operator closes the cover 28 and controls the process via the PLC on the front of the insulation box 22. The controller 4 presets drying parameters, such as the hot air temperature threshold and the tumbling frequency of the servo motor 35. Then, the heat-conducting plate 21 quickly receives the heat energy converted by the heat-collecting plate, and the suction fan 24 operates to generate negative pressure, drawing heat energy into the inside of the insulation box 22, causing the temperature inside the box to gradually rise. Simultaneously, the high-temperature air inside the insulation box 22 is continuously blown downwards, while two guide vanes 25 guide the hot air to flow towards the bottom right side of the insulation box 22. At this time, the hot air is delivered to the drying box 27 through the ventilation pipe 26. During this process, the temperature sensor 5 monitors the hot air temperature in real time and transmits the data to the PLC controller 4. When the temperature sensor... When the device 5 detects that the hot air temperature has reached the preset threshold of the PLC controller 4, the PLC controller 4 controls the suction fan 24 to maintain a stable speed. The PLC controller 4 makes real-time fine adjustments based on the temperature; if the temperature is too high, the speed is reduced, and if the temperature is too low, the speed is increased, ensuring that the hot air in the drying oven 27 is continuous and the temperature is stable. At the same time, the PLC controller 4 starts the servo motor 35. The output end of the servo motor 35 drives the fixed ring to rotate through the connecting shaft. The fixed ring further drives the placement shell 31 to rotate smoothly around the left rotating rod 32, realizing the turning of the material and allowing the material to come into uniform contact with the hot air. During this process, the placement shell 31 rotates smoothly around the left rotating rod 32. The mesh design at the bottom of the shell 31 and the inner side of the snap-fit ​​filter plate 37 ensures that hot air can penetrate the material layer. Finally, with the periodic turning of the servo motor 35 and the continuous action of the hot air, the moisture in the material gradually evaporates. The moisture generated by evaporation forms a slight positive pressure in the drying chamber 27 and is naturally discharged through the three exhaust vents 29. When the drying time is up, the PLC controller 4 turns off the suction fan 24 and the servo motor 35 in sequence. At this time, the operator opens the cover 28. After the power is cut off, the electro-adsorption magnet 38 loses its magnetism. The operator removes the snap-fit ​​filter plate 37 and takes out the dried material, completing the entire drying process.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
