The conveyor belt A1 reciprocally winds around some of the rollers, and the conveyor belt B2 reciprocally winds around some of the rollers. A material placement gap 3 is formed between the conveyor belt A1 and the conveyor belt B2. A flue gas pipe 4 is arranged above the conveyor belt A1 and the conveyor belt B2. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When setting the structure, the conveyor belt A1 and the conveyor belt B2 are set, and the conveyor belt A1 and the conveyor belt B2 respectively wind around different rollers, and the conveyor belt A1 and the conveyor belt B2 respectively reciprocally wind around, and reciprocally wind around different rollers under the flue gas pipe, thereby forming a multi-layer layout structure. There is a gap between the conveyor belt A1 and the conveyor belt B2, forming a material placement gap 3. The material to be dried 14 is fed from one side of the upper part of the device. When the material to be dried is dried, it is located in the material placement gap 3 and is restricted by the conveyor belt A1 and the conveyor belt B2 to achieve continuous transportation without displacement. When the material to be dried passes through the drying device, the conveyor belt A1 and the conveyor belt B2 clamp the material to be dried. The material to be dried repeatedly turns back and moves forward in the drying device. The flue gas with temperature supplied by the flue gas pipe 4 goes downward, passes through the conveyor belt A1 and the conveyor belt B2, and dries the material to be dried. In this way, it is possible to avoid the problem of uneven drying caused by the unconstrained material to be dried forming a stockpile when passing through the drying device, and improve the drying effect. The material drying device described in the utility model has a simple structure. During the material drying process, it effectively restricts the material to be dried, avoids the displacement of the material, avoids the problem of uneven drying caused by stockpiling, and improves the drying effect.

[0023] The described belt rollers include a left belt roller group 5 and a right belt roller group 6. The left belt roller group 5 includes a plurality of left belt rollers 7 arranged at intervals from top to bottom, and the right belt roller group 6 includes a plurality of right belt rollers 8 arranged at intervals from top to bottom. An upper left outer belt roller 9 is provided outside the uppermost left belt roller 7 of the left belt roller group 5, and a lower left outer belt roller 10 is provided outside the lowermost left belt roller 7 of the left belt roller group 5. A second upper right outer belt roller 11 is provided outside the second right belt roller 8 from the top of the right belt roller group 6, and a lower right outer belt roller 12 is provided outside the lowermost right belt roller 8 of the right belt roller group 6. A material output roller 13 is provided at the lower left position of the left belt roller group 5. The number of belt rollers in the right belt roller group 5 is more than that in the left belt roller group 5, and the uppermost left belt roller 7 of the left belt roller group 5 and the uppermost right belt roller 8 of the right belt roller group 6 are at the same height. With the above structure, by defining the arrangement positions of the left belt roller group 5, the right belt roller group 6, the upper left outer belt roller 9, the lower left outer belt roller 10, the upper right outer belt roller 11, the lower right outer belt roller 12, and the material output roller 13, the separate arrangements of conveyor belt A1 and conveyor belt B2 are realized, and a material placement gap 3 is formed between conveyor belt A1 and conveyor belt B2 for limiting the material. Either the upper left outer belt roller 9 or the lower left outer belt roller 10 is connected to a driving motor, and either the upper right outer belt roller 11 or the lower right outer belt roller 12 is connected to a driving motor to drive the conveyor belt.

[0024] Both the described conveyor belt A1 and conveyor belt B2 are annular closed conveyor belts. With the above structure, both conveyor belt A1 and conveyor belt B2 move reciprocally to realize the continuous conveying and drying of the material.

[0025] The conveyor belt A1 successively bypasses the uppermost right belt roller 8 of the right belt roller group 6, the upper left outer belt roller 9, the lower left outer belt roller 10, the second right belt roller 8 from the bottom of the right belt roller group 6, the second left belt roller 7 from the bottom of the left belt roller group 5, the fourth right belt roller 8 from the bottom of the right belt roller group 6, and the second left belt roller 7 from the top of the left belt roller group 5, and then winds back to the position of the uppermost right belt roller 8 of the right belt roller group 6. The conveyor belt B2 successively bypasses the lower right outer belt roller 12, the upper right outer belt roller 11, the second left belt roller 7 from the top of the left belt roller group 5, the third right belt roller 8 from the top of the right belt roller group 6, the second left belt roller 7 from the bottom of the left belt roller group 5, the second right belt roller 8 from the bottom of the right belt roller group 6, and the material output roller 13, and then winds back to the position of the lower right outer belt roller 12. With the above structure, the running directions of conveyor belt A1 and conveyor belt B2 are respectively defined, so that a material placement gap 3 for limiting the material to be dried is formed between conveyor belt A1 and conveyor belt B2 at the positions passing through the belt rollers.

[0026] From the position below the right belt roller 8 at the uppermost part of the right belt roller group 6 to the position above the material output roller 13, a continuous material placement gap 3 is formed between the conveyor belt A1 and the conveyor belt B2. The material to be dried 14 is clamped within the material placement gap 3.

When the material to be dried passes through the belt rollers, it is always located within the continuous material placement gap 3 formed between the conveyor belt A1 and the conveyor belt B2, and is constrained by the conveyor belt A1 and the conveyor belt B2, achieving continuous transportation without displacement. The material to be dried repeatedly folds back and moves forward in the drying equipment, and finally is sent away through the position of the material output roller 13. The temperature-bearing flue gas supplied by the flue gas pipe 4 moves downward, passes through the material to be dried, and dries the material to be dried. In this way, it avoids the problem of uneven drying caused by the unconstrained material to be dried forming a stockpile when passing through the drying equipment, and improves the drying effect.

[0027] In the material drying equipment described in the present utility model, when the structure is set, the conveyor belt A1 and the conveyor belt B2 are provided. The conveyor belt A1 and the conveyor belt B2 respectively bypass different belt rollers, and the conveyor belt A1 and the conveyor belt B2 respectively reciprocate around, and reciprocate around different belt rollers below the flue gas pipe, thus forming a multi-layer layout structure. There is a gap between the conveyor belt A1 and the conveyor belt B2, forming a material placement gap 3. The material to be dried 14 is fed from one side of the upper part of the equipment. When the material to be dried is dried, it is located within the material placement gap 3 and is constrained by the conveyor belt A1 and the conveyor belt B2, achieving continuous transportation without displacement. When the material to be dried passes through the drying equipment, the conveyor belt A1 and the conveyor belt B2 clamp the material to be dried. The material to be dried repeatedly folds back and moves forward in the drying equipment, and the temperature-bearing flue gas supplied by the flue gas pipe 4 moves downward, passes through the conveyor belt A1 and the conveyor belt B2, and dries the material to be dried. In this way, it avoids the problem of uneven drying caused by the unconstrained material to be dried 14 forming a stockpile when passing through the drying equipment, and improves the drying effect.
