AI Technical Summary
When existing refractory drying equipment accumulates, hot air is difficult to transfer to the inner layer, resulting in the inability to effectively diffuse the water vapor in the inner layer and the drying effect is poor.
The stepper motor drive gear system is used to drive the hollow rotary pipe to rotate, and the internal heating and air flow are combined with No. 1 air pump and heating pipe to increase pores to promote water vapor evaporation. At the same time, the No. 2 air pump and heating net are used to promote the movement of material particles and further bake.
It effectively improves the drying effect of refractory materials, ensures that the internal water vapor of the material evaporates and completes all-round drying within the heat resistance range.

However, when the materials are piled up in large quantities and almost fill the equipment, turning over will not have much effect. The hot air blown by the drying machine is still difficult to transmit to the inner layer of the materials. Moreover, when the materials are piled up, the water vapor inside cannot diffuse outwards. Therefore, the external drying method is difficult to achieve a good drying effect. Utility Model Content

[0021] See also Figure 1-4 A drying device for refractory materials includes a device body 1, a stepping motor 2 and a driven gear 4. The stepping motor 2 is fixedly mounted on the top of the device body 1, a driving gear 3 is fixedly mounted on the periphery of the bottom end of the stepping motor 2, and the driven gear 4 is meshed with the periphery of the driving gear 3.
[0022] Specifically, a hollow rotating tube 5 is fixedly installed on the inner wall of the driven gear 4, a fixing ring 6 is fixedly installed on the periphery of the hollow rotating tube 5, a connecting bearing 7 is overlapped and installed on the middle part of the fixing ring 6, a heating tube 8 is fixedly installed on the outer wall of the hollow rotating tube 5, a No. 1 air pump 9 is fixedly installed on the top rear of the equipment main body 1, a collecting box 17 is fit-fitted on the inner bottom of the equipment main body 1, a movable plate 18 is overlapped and installed on the front of the equipment main body 1, an exhaust pipe 19 is fixedly installed on the top right side of the equipment main body 1, and a feed pipe 20 is fixedly installed on the top left side of the equipment main body 1.
[0023] Through the above technical solution, when drying and blowing the material, the heating tube 8 can be powered on to heat the material from the inside, and then the stepper motor 2 can be started to drive the driving gear 3 to rotate, and then the driving gear 3 can drive the driven gear 4 to rotate through the gear meshing. Since the driven gear 4 and the hollow rotating tube 5 are fixed to each other, the driven gear 4 can drive the hollow rotating tube 5 to rotate synchronously, so that the heating tube 8 stirs the inside of the material, thereby increasing the pores between the materials. Since the hollow rotating tube 5 is a metal hollow tube and has through-type through-holes on its periphery and bottom, the No. 1 air pump 9 can be turned on and the air can be discharged to the middle part of the material through the through-holes inside the hollow rotating tube 5. The heat is conducted from the inside of the material to the outside through the flow of air, thereby achieving drying, and the enlarged pores between the materials are more conducive to the evaporation and discharge of water vapor from the inside to the outside.
[0024] Specifically, a guide pipe 10 is installed running through the interior of the equipment body 1, a solenoid valve 11 is installed on the outer wall of the guide pipe 10, a one-way valve 12 is installed on the bottom of the solenoid valve 11, a No. 2 air pump 13 is installed in front of the No. 1 air pump 9, a dispersed circulation pipe 14 is fixedly installed on the bottom of the No. 2 air pump 13, a heating net 15 is nested on the outer wall of the dispersed circulation pipe 14, and a heating guide plate 16 is installed on the bottom end of the dispersed circulation pipe 14.
[0025] Through the above technical solution, after the preliminary drying is completed, the solenoid valve 11 can be opened to allow the dried material to flow into the dispersion circulation pipe 14 through the solenoid valve 11 and the one-way valve 12. After part of the material enters the dispersion circulation pipe 14, the No. 2 air pump 13 can be started to introduce air flow into the dispersion circulation pipe 14, and the heating net 15 can be used to heat the air flow, so that the dispersed material particles can be pushed to move downward in the dispersion circulation pipe 14 by the hot air flow. At the same time, the heating net 15 on the inner wall of the equipment body 1 can heat and bake the moving material particles. When the material particles leave the dispersion circulation pipe 14 and fall on the heating guide plate 16, since the heating guide plate 16 is a metal plate with heating wires inside, the heating guide plate 16 is tilted at twenty-five degrees as a whole. The heating guide plate 16 can guide the material particles to the collection box 17 while performing the final baking and dehumidification step. During the process, the material particles are repeatedly heated, that is, the drying effect of the material particles is greatly guaranteed within the heat resistance range of the refractory material.
[0026] The working principle of the present utility model is: first, the heating tube 8 is energized to heat the material from the inside, and then the stepper motor 2 is started and the driving gear 3 is driven to rotate, so that the heating tube 8 stirs the inside of the material, thereby increasing the pores between the materials, and the No. 1 air pump 9 is turned on and the air is discharged to the middle part of the material through the through hole inside the hollow rotating tube 5. The heat is conducted from the inside of the material to the outside through the flow of air, thereby achieving drying, and the increased pores between the materials are more conducive to the evaporation and discharge of water vapor from the inside to the outside. After the material enters the dispersed circulation tube 14, the No. 2 air pump 13 can be started and air flow can be passed into the dispersed circulation tube 14, and the heating network 15 can heat the air flow at the same time, and then the dispersed material particles can be pushed to move downward in the dispersed circulation tube 14 by the hot air flow. In the process, the material particles are repeatedly heated, that is, the drying effect of the material particles is greatly guaranteed within the heat resistance range of the refractory material.
[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
