[0037] Combination Figure 1-6 As shown, this embodiment of the present disclosure provides a mesh belt drying device, including: a drying chamber 100, which is a rectangular box structure with an opening at the top; an upper drying mesh belt 200, which is an annular mesh belt structure, the upper drying mesh belt 200 being arranged laterally within the drying chamber 100, and upper support rollers 201 supporting the upper drying mesh belt 200 being provided at both ends of the inner side of the upper drying mesh belt 200; multiple lower steering rollers 300, which are arranged side by side on the inner side of the annular upper drying mesh belt 200; and an upper steering roller 301, which is disposed below the lower steering rollers 300 and is pressed against the outer side of the annular upper drying mesh belt 200, the upper drying mesh belt 200 in contact with the lower steering rollers 300 and the upper steering rollers 301 having an S-shaped structure;

[0038] A heat exchange device is installed at the lower part of the upper drying mesh belt 200.

[0039] The mesh belt drying equipment provided in this embodiment has a drying chamber 100 that is a rectangular box structure with an open top. A heat exchange device is installed in the middle, and an upper drying mesh belt 200 is installed above the heat exchange device. The upper drying mesh belt 200 is a breathable annular mesh belt structure, allowing hot air generated by the heat exchange device to pass through the mesh belt from bottom to top, thus heating and drying the material on the upper drying mesh belt 200. Upper support rollers 201 are respectively installed on the inner sides of both ends of the upper drying mesh belt 200, and the upper support rollers 201 are rotatably mounted on the drying... On the side wall of the silo 100, the rotation of the upper support roller 201 drives the upper drying mesh belt 200 to rotate cyclically. Multiple lower guide rollers 300 are arranged side-by-side on the inner upper part of the annular upper drying mesh belt 200. An upper guide roller 301 is positioned on one side of the lower guide roller 300, pressing against the outer side of the upper drying mesh belt 200. This pulls the upper drying mesh belt 200 downwards on the lower guide rollers 300, causing the upper drying mesh belt 200 to form an S-shape between the lower guide rollers 300 and the upper guide roller 301. The upper drying mesh belt 200 is designed so that when the material moves along the upper part of the upper drying mesh belt 200, it turns at the lower turning roller 300 due to the S-shaped structure. This causes the material to fall directly onto the upper drying mesh belt 200 after being pressed down by the upper turning roller 301. During the fall, the material tumbles and disperses, breaking up the material accumulation. This allows even thick layers of material to tumble and disperse during the fall, effectively preventing the bottom from drying while the top remains damp, thus improving overall drying uniformity and efficiency. It also effectively stirs and loosens the material, further enhancing hot air penetration and ensuring uniform heating during the drying process. Furthermore, the lower turning roller 300 and upper turning roller 301 are configured in multiple sets, allowing for adjustment of the spacing and number according to actual working conditions. This enables the material to tumble and disperse multiple times on a single upper drying mesh belt 200, effectively achieving a multiple-fold tumbling and falling drying process, significantly improving the uniformity of material drying and heat utilization efficiency.

[0040] Optionally, there are multiple upper drying mesh belts 200, which are arranged vertically in parallel, and adjacent upper drying mesh belts 200 rotate in opposite directions.

[0041] In this way, by setting up multiple parallel upper drying mesh belts 200, each upper drying mesh belt 200 forms an S-shaped winding structure with the upper turning roller 301 via the lower turning roller 300. The upper drying mesh belt 200 can be set as a three-layer structure or more layers. In the three-layer structure, one end of the upper layer of the upper drying mesh belt 200 is used for feeding, and one end of the middle upper drying mesh belt 200 extends out from the material discharge end of the upper drying mesh belt. In this way, the material on the upper drying mesh belt can fall directly into the middle upper drying mesh belt 200. The feeding direction of the middle upper drying mesh belt 200 is opposite to that of the upper upper drying mesh belt 200. This allows the material to be conveyed in reverse from the middle upper drying mesh belt 200 to the lower upper drying mesh belt 200. The feeding direction of the lower upper drying mesh belt 200 is the same as that of the upper upper drying mesh belt 200. This allows the material to be conveyed back and forth through the three upper drying mesh belts 200, which increases the number of times the material is turned and the residence time during the drying process, further improving the drying uniformity and thermal efficiency.

[0042] Optionally, a lower drying mesh belt 400 is provided at the lower part of the heat exchange device. The lower drying mesh belt 400 has a ring structure and is located directly below the upper drying mesh belt 200. Lower support rollers 401 are provided on the inner sides of both ends of the lower drying mesh belt 400.

[0043] Thus, the lower drying mesh belt 400 at the bottom of the heat exchange device is a ring-shaped mesh belt structure, located directly below the upper drying mesh belt 200. It can be used to receive the material falling after drying on the upper drying mesh belt 200, and at the same time perform secondary drying treatment on the material. The heat exchange device can heat the bottom of the lower drying mesh belt 400 with hot air, so that the hot air passes through the lower drying mesh belt 400 from bottom to top, further removing residual moisture from the surface of the material. Lower guide rollers 300 are provided on the inner sides of both ends of the lower drying mesh belt 400, and the lower guide rollers 300 are rotatably mounted on the side wall of the drying chamber 100. The mesh belt can be supported to achieve its cyclic operation. The lower drying mesh belt 400 can have two or more layers. When it is double-layered, the upper lower drying mesh belt 400 receives the material falling from the upper upper drying mesh belt 200. After being dried by the upper lower drying mesh belt 400, the material falls into the lower lower drying mesh belt 400, and the second lower drying mesh belt 400 continues to complete the drying process. The two layers are also conveyed in opposite directions. The second lower drying mesh belt 400 can output the dried material from the drying chamber 100, thereby realizing continuous and efficient drying of the material.

[0044] Optionally, a guide plate 202 is provided at the end of the adjacent upper drying mesh belt 200, and the guide plate 202 is inclined toward the upper part of the lower upper drying mesh belt 200. A guide plate 202 is provided at the end of the adjacent lower drying mesh belt 400, and the guide plate 202 is inclined toward the upper part of the lower lower drying mesh belt 400. A guide plate 202 is provided on one side between the upper drying mesh belt 200 and the lower drying mesh belt 400, and the guide plate 202 is inclined toward the upper part of the lower drying mesh belt 400.

[0045] In this way, both the upper drying mesh belt 200 and the lower drying mesh belt 400 are multi-layered, and the material is transferred in an orderly manner through the guide plate 202. The guide plate 202 is inclined to effectively guide the material to fall smoothly into the lower mesh belt. When the upper drying mesh belt has three layers and the lower drying mesh belt 400 has two layers, the upper drying mesh belt is equipped with a guide plate 202 at the end of the conveying end. The guide plate 202 can smoothly guide the material into the middle upper drying mesh belt 200. The middle upper drying mesh belt 200 is also equipped with a guide plate 202 at the end of the conveying end to guide the material to the lower upper drying mesh belt 200. The guide plate 202 at the end of the lower upper drying mesh belt 200 guides the material into the upper lower drying mesh belt 400. After being dried by the upper lower drying mesh belt 400, the material is guided into the lower lower drying mesh belt 400 through the guide plate 202 for final drying, ensuring that the material is transferred smoothly between each level of mesh belt and avoiding spillage or accumulation caused by the material not falling accurately into the lower mesh belt.

[0046] Optionally, a feed inlet 101 is provided on the upper part of one side of the drying chamber 100, one end of the uppermost drying mesh belt 200 extends out of the drying chamber 100 through the feed inlet 101, and a discharge outlet 102 is provided on the lower part of one side of the drying chamber 100, one end of the lowermost drying mesh belt 400 extends out of the drying chamber 100 through the discharge outlet 102.

[0047] In this way, a feed inlet 101 is provided at one end of the drying chamber 100. The feed inlet 101 allows one end of the uppermost drying mesh belt 200 to extend outside the chamber, facilitating material input. The discharge outlet 102 is located at the lower part of one side of the drying chamber 100, allowing one end of the lowermost drying mesh belt 400 to extend outside the chamber, facilitating the smooth discharge of dried material, realizing continuous feeding and discharging, and improving drying efficiency.

[0048] Optionally, the heat exchange device includes: a heat exchange fan 500, disposed inside one side of the drying chamber 100; a heat exchanger 501, connected to the heat exchange fan 500, the heat exchange fan 500 driving air flow, and the heat exchanger 501 disposed at the lower part of the upper drying mesh belt 200; a heat exchange air chamber 502, connected to the heat exchange fan 500, the heat exchange air chamber 502 extending to the side of the upper drying mesh belt 200; and several hot air pipes 503, arranged side by side between the upper drying mesh belts 200, the hot air pipes 503 connected to the side wall of the heat exchange air chamber 502, and several air outlets 504 arranged side by side on the upper side wall of the hot air pipes 503.

[0049] Thus, the heat exchange device includes: a heat exchange fan 500, a heat exchanger 501, a heat exchange air chamber 502, and hot air pipes 503. The heat exchanger 501 can exchange heat and raise the temperature of the air inside the drying chamber 100. The heat exchange fan 500 can draw in the hot air heated by the heat exchanger 501 and send it into the heat exchange air chamber 502. The heat exchange air chamber 502 discharges the hot air through the parallel hot air pipes 503. The heat exchanger 501 is located at the lower part of the upper drying mesh belt 200. The heat exchange fan 500... A heat exchanger 501 is installed on one side of the drying chamber 100. The heat exchange fan 500 is connected to the heat exchange chamber 502. The heat exchange chamber 502 is located on the side of the upper drying mesh belt 200 and is connected to the hot air pipe 503. The hot air pipe 503 runs through the upper drying mesh belt 200 and extends into the annular structure of the upper drying mesh belt 200. The air outlets 504 at the top of the hot air pipe 503 are evenly distributed to ensure that hot air penetrates the material layer from bottom to top and improves the drying uniformity.

[0050] Optionally, the heat exchanger 501 is disposed between the upper drying mesh belt 200 and the lower drying mesh belt 400. The heat exchanger 501 is connected to the heat exchange air chamber 502 through a heat exchange fan 500. The heat exchange air chamber 502 is disposed on one side of the upper drying mesh belt 200 and the lower drying mesh belt 400 respectively. The hot air pipes 503 on the side of the heat exchange air chamber 502 extend into the interior of the upper drying mesh belt 200 and the lower drying mesh belt 400 respectively.

[0051] Thus, the heat exchanger 501 is positioned between the upper drying mesh belt 200 and the lower drying mesh belt 400. The heat exchange fan 500 draws the heated air from the heat exchanger 501 and delivers it to the heat exchange air chamber 502. The heat exchange air chambers 502 are positioned on one side of both the upper and lower drying mesh belts 400. The hot air pipe 503 extends from the heat exchange air chamber 502 and passes between the upper and lower drying mesh belts 400. The air outlets 504 are evenly distributed upwards, allowing the hot air to penetrate the material layers on the upper and lower drying mesh belts 400 from bottom to top. The material on the upper drying mesh belt 200 has a shorter drying time and higher humidity, resulting in more water vapor being generated during drying. The material on the lower drying mesh belt 400 has low moisture content but needs continuous dehydration. The heat exchanger 501 can reheat part of the dry air with heat on the lower drying mesh belt 400 to improve the heat energy utilization rate. Fresh air can also flow into the bottom of the drying chamber 100. In this way, the heat exchanger 501 can mix and heat the fresh air with the recovered hot air to further improve the heat exchange efficiency. The hot air dried by the upper drying mesh belt 200 is discharged through the exhaust port at the top of the drying chamber 100. The bottom part is mixed with fresh air after the waste heat is recovered by the heat exchanger 501 and enters the heat exchanger 501 for secondary heating to achieve energy saving and consumption reduction.

[0052] Optionally, the drying chamber 100 has a rectangular box structure, and an exhaust port 103 is provided at the top of the drying chamber 100. A support plate 104 is provided at the bottom of the drying chamber 100, and the support plate 104 covers the bottom of the drying chamber 100. Several air inlets 105 are provided on the support plate 104.

[0053] In this way, the exhaust vent 103 at the top of the drying chamber 100 facilitates the discharge of hot and humid air, and the support plate 104 at the bottom of the drying chamber 100 can effectively support the overall weight of the drying chamber 100 and enhance structural stability. Several air inlets 105 on the support plate 104 are evenly distributed to ensure that fresh air from the outside smoothly enters the drying chamber 100 from the bottom, and then mixes with the hot air transported by the hot air pipe 503 and flows upward to form a uniform hot air circulation. This can carry the moisture of the material on the lower drying mesh belt 400 to the heat exchanger 501. After being heated by the heat exchanger 501, it is sent into the heat exchange air chamber 502, and then transported to the space between the upper and lower drying mesh belts 400 through the hot air pipe 503 on the side of the heat exchange air chamber 502, thereby continuously and uniformly drying the material in the upper and lower drying mesh belts 400.

[0054] Optionally, a support base 106 is provided around the lower side of the support plate 104, and an air inlet 107 is provided on the side of the support base 106.

[0055] In this way, the support base 106 surrounding the lower part of the support plate 104 can support the entire support plate 104, separating the support plate 104 from the ground. The air inlet 107 on the side of the support base 106 facilitates the inflow of external air, which then enters the bottom of the drying chamber 100 through the air inlet 105 on the support plate 104. This allows air to easily enter the interior of the drying chamber 100 while preventing debris on the ground from clogging the air inlet 105.

[0056] Optionally, a drive motor 600 is provided on the upper support roller 201 and the lower support roller 401 respectively.

[0057] Thus, the upper drying mesh belt 200 and the lower drying mesh belt 400 are multi-layered. The material in the upper layer has a shorter drying time and a higher moisture content, resulting in a larger overall volume. The material in the lower layer, due to its lower moisture content, shrinks in volume. When the upper drying mesh belt 200 has three layers and the lower drying mesh belt 400 has two layers, the material in the upper drying mesh belt 200 has a high moisture content and a larger volume, and its conveying speed is stable. The material in the middle upper drying mesh belt 200 has a moderate moisture content and a slightly slower operating speed. The material in the lower upper drying mesh belt 200 is nearly dried, and its conveying speed is slower. The material falling into the lower drying mesh belt 400 undergoes tumbling and drying, resulting in a significant reduction in volume. The lower drying mesh belt 400 then continues to slow down its conveying speed according to the degree of dryness of the material. This ensures that the material is evenly spread on the mesh belt, preventing material from failing to spread or becoming fragmented due to excessive speed of the lower drying mesh belt 400. It also increases the drying time of the lower layer of material, ensuring a uniform and thorough drying effect. By setting independent drive motors 600 on the upper support rollers 201 and lower support rollers 401 of each layer of the upper drying mesh belt 200 and lower drying mesh belt 400, precise control of the conveying speed of each layer of mesh belts can be achieved. This adapts to the changes in material characteristics at different drying stages, effectively avoiding accumulation or tearing problems caused by speed mismatch. At the same time, it improves drying efficiency and energy consumption utilization, ensuring that the material is heated evenly and dehydrated in a coordinated manner during continuous dynamic drying, ultimately achieving the best drying quality and production stability.
