[0002] Degradable materials are a class of materials that can be naturally decomposed under specific environmental conditions (such as microorganisms, light, humidity, etc.), aiming to reduce the long-term environmental pollution caused by traditional materials such as plastics.

[0003] The prior art (publication number: CN219656542U) discloses a dehumidifying dryer for the preparation of biodegradable materials, which belongs to the field of dryer technology and solves the problem of low dehumidifying and drying efficiency. Its key technical points are: it includes a dryer body, and the dryer body is provided with a feeding hopper for feeding materials. The biodegradable materials to be dried are fed into the interior of the dryer body through the feeding hopper.

[0004] Existing technologies dry and dehumidify materials by vibrating and stirring them within the device. While these technologies can dry the materials, they also have a high probability of causing blockages in the auger during material transport. Furthermore, the air outlets of these technologies are highly susceptible to material entering the degradable material during vibration and transport, resulting in a high failure rate.

[0005] In view of this, this utility model is proposed. Utility Model Content

The top opening of the bulk material tube is aligned with the bottom opening of the feed tube.

[0013] In a preferred embodiment of this utility model, the air-holding structure further includes a guide plate, a fixed pipe, a rotating shaft, a rotating tube, and scrapers. The guide plate is fixedly connected to the bottom of the drying chamber. The fixed pipe is also fixedly connected to the bottom of the drying chamber and is cylindrical. The rotating shaft is rotatably connected to the cavity of the fixed pipe, and the top of the rotating shaft can be fixedly connected to the center of the bottom of the distribution pipe. The rotating tube is fixedly connected to the bottom of the distribution pipe and is cylindrical. The rotating shaft can be located inside the cavity of the rotating tube. The rotating tube can pass through the center of the upper distribution ring and be fixedly connected to the upper distribution ring. The walls of both the fixed pipe and the rotating tube are provided with multiple circular holes. The bottom of the cavity of the fixed pipe can communicate with the cavity of the air outlet pipe.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 and Figure 2 As shown, a degradable material drying and dehumidification processing device includes: a housing 20, which is a hollow rectangular box with legs installed at the bottom; a feed pipe 21 is fixedly connected to the top of the housing 20; a discharge port 22 is opened on one side of the bottom of the housing 20; a discharge pipe 26 is fixedly connected to the discharge port 22; the feed pipe 21 and the discharge pipe 26 are cylindrical; and a motor 23 is also fixedly connected to the bottom of the housing 20.

[0030] The hot air blower 24 is fixedly connected to the bottom of one side of the cavity of the housing 20. An air outlet pipe 25 is fixedly connected to one side of the hot air blower 24. The air outlet pipe 25 can communicate with the cavity of the hot air blower 24. The motor 23 and the air outlet pipe 25 are electrically connected to the corresponding power supply. This is existing technology, so it will not be described in detail here.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a stagnation structure is installed inside the cavity of the casing 20 to stagnate the degradation material inside the cavity of the casing 20. The stagnation structure includes: a drying chamber 30, a top pipe 31, an upper distribution ring 32, a lower distribution ring 33, a lower material distribution ring 36, a material distribution pipe 40, and an upper material distribution ring 43. The drying chamber 30 is fixedly connected inside the cavity of the casing 20 and is in the shape of a hollow cylindrical tube. The top pipe 31 is fixedly connected to the top of the cavity of the drying chamber 30 and is also in the shape of a hollow cylindrical tube. The upper distribution ring 32 is fixedly connected inside the cavity of the top pipe 31. The lower distribution ring 33 is fixedly connected inside the cavity of the drying chamber 30. The lower material distribution ring 36 is located inside the cavity of the drying chamber 30. The material distribution pipe 40 is located inside the cavity of the top pipe 31. The upper material distribution ring 43 is located below the material distribution pipe 40.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the upper dividing ring 32 is a circular ring with a right-angled triangular cross-section. The material distribution pipe 40 is located above the upper dividing ring 32. The lower dividing ring 33 is also a circular ring with a right-angled triangular cross-section. The upper dividing ring 43 is located below the upper dividing ring 32, and the lower dividing ring 36 is located below the upper dividing ring 43. The upper dividing ring 43 and the lower dividing ring 36 are frustum-shaped, with the lower dividing ring 36 located below the lower dividing ring 33. The material distribution pipe 40 is a hollow cross-shaped block, and the top of the material distribution pipe 40 is open. In this state, the four ends of the bulk material pipe 40 are also open. The top opening of the bulk material pipe 40 is aligned with the bottom opening of the feed pipe 21. The suspended structure also includes a guide plate 34, a fixed pipe 35, a rotating shaft 37, a rotating pipe 42, and a scraper 44. The guide plate 34 is fixedly connected to the bottom of the drying chamber 30. The fixed pipe 35 is fixedly connected to the bottom of the drying chamber 30 and is cylindrical. The rotating shaft 37 is rotatably connected to the cavity of the fixed pipe 35. The top of the rotating shaft 37 can... The fixed pipe 35 is fixedly connected to the bottom center of the bulk material pipe 40, and the rotating pipe 42 is fixedly connected to the bottom of the bulk material pipe 40. The rotating pipe 42 is cylindrical, and the rotating shaft 37 can be located inside the cavity of the rotating pipe 42. The rotating pipe 42 can pass through the center of the upper material distribution ring 43 and be fixedly connected to the upper material distribution ring 43. The walls of both the fixed pipe 35 and the rotating pipe 42 are provided with multiple round holes. The bottom of the cavity of the fixed pipe 35 can communicate with the cavity of the air outlet pipe 25, and the air outlet pipe 25 can drive the rotating shaft 37 to rotate. The scraper 44 is symmetrically and fixedly connected to the bottom of the upper distribution ring 43. The scraper 44 is a right-angled trapezoidal plate. The inclined surface of the scraper 44 can fit with the inclined surface of the lower distribution ring 33. A rectangular plate is also fixedly connected to the bottom of each scraper 44. The rectangular plate at the bottom of the scraper 44 is located in the cavity of the lower distribution ring 33. The guide plate 34 is an elliptical plate. The guide plate 34 is inclined at the bottom of the drying chamber 30. The lowest point of the inclined surface of the guide plate 34 can be aligned with the opening of the discharge pipe 26.

[0033] In practical use, the power is turned on and the material to be dried is poured in through the opening at the top of the feed pipe 21. When the power is on, the hot air blower 24 delivers hot air through the air outlet 25 into the solid pipe 35. The hot air moves upwards through the solid pipe 35 into the rotating pipe 42. During this movement, some hot air exits through the round holes along its path and enters the drying chamber 30 to contact the degradable material. When the degradable material enters the feed pipe 21, it falls directly into the distribution pipe 40. The distribution pipe 40 rotates when the motor 23 is turned on, driven by the rotating shaft 37. The rotating distribution pipe 40 throws the degradable material into the top pipe 31. When the degradable material enters the cavity of the jacking pipe 31, it will fall downwards onto the inclined surface of the upper dividing ring 32. When the degradable material falls onto the inclined surface of the upper dividing ring 32, it will move towards the central opening of the upper dividing ring 32. When the degradable material moves downwards from the gap between the central opening of the upper dividing ring 32, it will fall onto the top inclined surface of the lower dividing ring 33. Then, the rotating upper dividing ring 43 will drive the scraper 44 to scrape along the inclined surface of the lower dividing ring 33. The rotating scraper 44 can scrape the degradable material to move on the inclined surface of the lower dividing ring 33. When the degradable material falls from the gap between the center of the lower dividing ring 33 and the solid pipe 35, it will fall onto the inclined surface of the guide plate 34. Finally, it will enter the cavity of the discharge pipe 26 along the inclined surface of the guide plate 34 and be discharged from the discharge port 22.

[0034] In summary, by setting up a suspended structure, the degradable material to be dried can undergo multiple suspended phases when in contact with hot air. Furthermore, the swaying of the material distribution pipe 40 and the scraping of the scraper 44 can effectively prevent the degradable material from clumping. The movement of the degradable material within the device relies entirely on gravity and inertia. This solution has a compact structure, and the spacing between the top pipe 31 and the cavity of the casing 20 provides good insulation. The probability of blockage is extremely low, and maintenance is also relatively simple.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, a blower plate 38 is fixedly connected to the bottom arc surface of the rotating shaft 37. The blower plate 38 is rectangular. Multiple blower plates 38 are evenly arranged on the arc surface of the rotating shaft 37. A cone 41 is fixedly connected to the center of the cavity of the material distribution pipe 40. The cone 41 is conical. The top of the cone 41 is flush with the top of the material distribution pipe 40.

[0036] In practical use, when the rotating shaft 37 rotates, it will drive the blowing plate 38 to rotate synchronously. When the blowing plate 38 rotates, it can blow the hot air in the solid tube 35 upward. When the degradation material enters the dispersing tube 40, it will come into contact with the cone 41. The cone 41 can break up the clump of degradation material.

[0037] In summary, by setting the blowing plate 38, the flow rate of hot air inside the device can be increased, which can effectively increase the time for hot air to enter the drying chamber 30, thereby reducing the preheating time required for the device. By setting the piercing cone 41, the degradation material initially entering the device can be directly pierced and dispersed.

[0038] Working principle: When the power is turned on, the material to be dried is poured into the feed pipe 21 through the opening at the top. When the power is turned on, the hot air blower 24 delivers hot air to the solid pipe 35 through the air outlet 25. The hot air moves upward through the solid pipe 35 to the rotating pipe 42. During the movement of the hot air, some of it is discharged through the round holes along the way and enters the drying chamber 30 to contact the material being dried. When the material is introduced into the feed pipe 21, it falls directly into the distribution pipe 40. The distribution pipe 40 is rotated by the rotating shaft 37 when the motor 23 is turned on. The rotating distribution pipe 40 throws the material in its chamber into the top pipe 31. When the degradable material enters the cavity of the jacking pipe 31, it falls downwards onto the inclined surface of the upper dividing ring 32. As the degradable material falls onto the inclined surface of the upper dividing ring 32, it moves towards the central opening of the upper dividing ring 32. When the degradable material moves downwards from the gap between the central opening of the upper dividing ring 32, it falls onto the top inclined surface of the lower dividing ring 33. Then, the rotating upper dividing ring 43 drives the scraper 44 to scrape along the inclined surface of the lower dividing ring 33. The rotating scraper 44 can scrape the degradable material to move on the inclined surface of the lower dividing ring 33. When the degradable material falls from the gap between the center of the lower dividing ring 33 and the solid pipe 35, it falls onto the inclined surface of the guide plate 34. Finally, it enters the cavity of the discharge pipe 26 along the inclined surface of the guide plate 34 and is discharged from the device at the discharge port 22.
