[0025] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be understood broadly, and the skilled person in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0026] The embodiments of the present application are described below in combination with Figures 1 to 6 The embodiments of the present application are described below in combination with

[0027] As Figure 1 shown, the present embodiment relates to a waste heat drying and screening device, which comprises a dryer 100, the dryer 100 comprising a box body 200, an air outlet channel 300 and an air inlet pipeline 400, the right side of the box body 200 being provided with a drying inlet 5, the left side of the box body 200 being provided with a drying outlet 6, the bottom of the box body 200 being provided with an air inlet 7, and the top of the box body 200 being provided with an air outlet 8.

[0028] The air outlet 8 is communicated with the air outlet channel 300, and the first valve 9 is arranged on the air outlet channel 300. The air inlet pipeline 400 is communicated with the air inlet 7, and the circulating fan 10, the temperature and air volume sensing assembly, the shunt pipeline 11 and the second valve 12 are arranged on the air inlet pipeline 400. The circulating fan 10, the temperature and air volume sensing assembly, the shunt pipeline 11 and the second valve 12 are sequentially arranged in the order from near to far with respect to the distance from the air inlet 7. The shunt pipeline 11 is communicated with the air outlet channel 300, the shunt pipeline 11 is connected between the air outlet 8 and the first valve 9, and the third valve 13 is arranged on the shunt pipeline 11.

[0029] The material is conveyed between the drying material inlet 5 and the drying material outlet 6 through the mesh conveyor belt assembly, that is, the material on the material inlet is conveyed to the drying material outlet 6 through the mesh conveyor belt assembly. The mesh conveyor belt assembly at least includes two one-way conveyor belts 14 and one two-way conveyor belt 15. The one-way conveyor belts 14 and the two-way conveyor belt 15 are arranged in an upper and lower adjacent mode, and the two-way conveyor belt 15 is arranged in a left and right staggered mode with respect to the one-way conveyor belts 14. In the embodiment, four one-way conveyor belts 14 are arranged, and three two-way conveyor belts 15 are arranged.

[0030] Thus, on the basis of the above structure, the use principle is as follows: the air inlet 7 is connected with the tail gas pipe of the kiln through the air inlet pipeline 400. The waste heat gas in the kiln enters the inside of the box body 200 from the air inlet 7 through the air inlet pipeline 400. Thus, at the same time, the material to be dried enters the inside of the box body 200 from the material inlet and is conveyed to the drying material outlet 6 under the conveying action of the mesh conveyor belt assembly. The waste heat gas and the material meet in the inside of the box body 200 to exchange heat. Under the action of the waste heat gas, the material is gradually dried. Then, the waste heat gas is discharged from the air outlet 8 to the outside of the box body 200 through the air outlet channel 300. At this time, the mesh structure of the mesh conveyor belt assembly facilitates the gas to pass through, so as to improve the drying effect. At the same time, in the whole process, the temperature and air volume sensing assembly is used to monitor the temperature and air volume state of the hot air in real time.

[0031] As shown in the first use case in FIG. 6, when the flow of the waste heat gas in the kiln is appropriate, the third valve 13 is closed. The waste heat gas in the air inlet pipeline 400 enters the inside of the box body 200 from the air inlet 7 and is discharged from the air outlet 8. Figure 1 As shown in the second use case in FIG. 6, when the flow of the waste heat gas in the kiln is too large (greater than the design flow required for drying), the third valve 13 is controlled to be opened. Thus, the waste heat gas in the air inlet pipeline 400 can be shunted through the shunt pipeline 11, so as to facilitate the control of the flow of the waste heat gas in the box body 200. Figure 2 Figure 3 ​As shown, the third use case: when the temperature of the residual heat gas in the kiln is high, the conveying direction of the bidirectional conveying belt 15 is consistent with the conveying direction of the unidirectional conveying belt 14, thereby facilitating to reduce the conveying time of the material in the box body 200 and improve the drying efficiency of the residual heat drying and screening device. Figure 1 As shown, the fourth use case: when the temperature of the residual heat gas in the kiln is moderate or low, the conveying direction of the bidirectional conveying belt 15 is opposite to the conveying direction of the unidirectional conveying belt 14, thereby facilitating to change the conveying path of the material, improve the conveying time of the material in the box body 200, and guarantee the drying quality of the residual heat drying and screening device. As shown, Figure 4 As shown, the fifth use case: when the temperature of the residual heat gas in the air inlet pipeline 400 is high and there is no residual heat gas supply in the kiln, the first valve 9 and the second valve 12 are closed at the same time, and the circulating fan 10 is opened, so that the residual heat gas continuously circulates in the air inlet pipeline 400, the box body 200, the air outlet channel 300 and the shunt pipeline 11, thereby improving the use rate of the residual heat gas, guaranteeing that the equipment can still be continuously supplied for a period of time without the supply of the kiln residual heat gas, and effectively avoiding the shutdown of the equipment.

[0032] Therefore, the present application sets the air inlet pipeline 400, the box body 200, the air outlet channel 300 and the mesh conveying belt assembly to realize the effect of drying the material by using the residual heat gas. At the same time, the first valve 9, the circulating fan 10, the temperature and air volume sensing assembly, the shunt pipeline 11, the second valve 12, the third valve 13 and the bidirectional conveying belt 15 are set, so that the equipment can normally perform drying work and guarantee the drying quality when the residual heat gas flow is appropriate, the flow is too large, the temperature is high, the temperature is moderate and low, and the temperature is high and there is no continuous supply of residual heat gas. Therefore, the present application can achieve the recycling of residual heat gas and effectively deal with the unstable situation of residual heat gas.

Thus, on the basis of the above structure, when the material output from the drying discharging port 6 meets the drying requirements, the first conveying belt 17 is used to convey the material on the drying discharging port 6 to the screening feeding port 20 for screening operation, when the material output from the drying discharging port 6 does not meet the drying requirements, the reversing conveying plate 19 is rotated, so that the first conveying belt 17 conveys the material on the drying discharging port 6 to the second conveying belt 18, and then the second conveying belt 18 conveys the material to the drying feeding port 5 again, so that the material can be dried again, thereby avoiding the problem of substandard drying quality.

In this embodiment, the air inlets 7 are provided with four, and the air outlets 8 are provided with four, the air inlets 7 and the air outlets 8 are arranged in corresponding positions.
