As the two arc-shaped reflectors 17 continue to fall, the two arc-shaped reflectors 17 come into contact with each other, thereby forming a large reflector. At this time, the upper surfaces of the softened water vacuum heat collection tube 2 and the heat transfer oil vacuum heat collection tube 3 are exposed and in contact with sunlight. At the same time, the sunlight is reflected by the upper surfaces of the two arc-shaped reflectors 17, so that the lower surfaces of the softened water vacuum heat collection tube 2 and the heat transfer oil vacuum heat collection tube 3 can also receive the sunlight, so that the softened water vacuum heat collection tube 2 and the heat transfer oil vacuum heat collection tube 3 heat the softened water and the heat transfer oil respectively.

[0048] At the same time, the double-head circulation motor 12 starts to work, and controls the two electromagnetic clutches 13 to be turned on, so that the double-head circulation motor 12 drives the softened water impeller 7 and the heat transfer oil impeller 11 to rotate, so that the softened water impeller 7 drives the softened water in the softened water tank 4 to circulate, and the heat transfer oil impeller 11 drives the heat transfer oil in the heat transfer oil tank 8 to circulate, so that the softened water and the heat transfer oil are heated respectively, and the temperatures of the softened water and the heat transfer oil can be detected by a thermal resistance thermometer;

[0049] When the temperature of the softened water reaches the set value, the driving motor 24 at the softened water vacuum heat collection pipe 2 is controlled to work in the reverse direction, so that the two arc-shaped reflectors 17 start to rise and the upper ends of the two arc-shaped reflectors 17 are in contact, so as to shield the upper part of the softened water vacuum heat collection pipe 2, and at the same time, the shading soft cloth 72 shields the lower part of the softened water vacuum heat collection pipe 2, so as to prevent the softened water vacuum heat collection pipe 2 from being heated, and the electromagnetic clutch 13 at the softened water impeller 7 is controlled to stop working, so that the softened water impeller 7 stops rotating, so that the softened water is heat-insulated;

[0050] When the temperature of the heat transfer oil reaches the set value, the drive motor 24 at the heat transfer oil vacuum heat collection pipe 3 is controlled to work in the reverse direction, so that the two arc-shaped reflectors 17 start to rise and the upper ends of the two arc-shaped reflectors 17 are in contact, so as to shield the upper part of the heat transfer oil vacuum heat collection pipe 3, and at the same time, the shading soft cloth 72 shields the lower part of the heat transfer oil vacuum heat collection pipe 3, so as to prevent the heat transfer oil vacuum heat collection pipe 3 from being heated, and the electromagnetic clutch 13 at the heat transfer oil impeller 11 is controlled to stop working, and at the same time, the double-head circulation motor 12 is controlled to stop working, so that the heat transfer oil impeller 11 stops rotating, so that the softened water is insulated, and the temperature of the heat transfer oil at this time is within the safe use range of the heat transfer oil;

[0051] When it is necessary to dry the building materials, the staff first opens the sealing door 73 and places the building materials into the drying chamber 41 inside the drying box 1. The building materials can be placed separately by the grid-type placing rack so that the building materials can be fully heated and dried. When the building materials are placed, the staff manually closes the sealing door 73 so that the sealing door 73 seals the drying box 1.

[0052] At this time, the desiccant box 57 in one of the fixed boxes 52 is connected to the two evaporation tubes 56, and the desiccant box 57 in the other fixed box 52 is connected to the fixed box 52, and the air pressure inside the drying box 1 is at normal pressure;

[0053] At this time, the vacuum pump 48 is controlled to start working. The vacuum pump 48 extracts air through the vacuum pipeline composed of the air inlet pipe 47, one of the fixed boxes 52, the connecting pipe 53, the other fixed box 52 and the drying inlet pipe 54, so that the air inside the drying chamber 41 is pumped into the air compression tank 46, so that the air in the air compression tank 46 is compressed, and at the same time, a low-pressure environment is formed inside the buffer chamber 40, the drying chamber 41 and the heat exchange chamber 42, and the air pressure in the drying chamber 41 is detected by the air pressure sensor 43. When the air pressure inside the drying chamber 41 is lower than the set value, the control valve 51 is opened at this time, and the air flow regulating valve 50 starts to adjust the air discharge flow inside the air outlet pipe 49. The air flow regulating valve 50 makes the air flow in the air outlet pipe 49 the same as the air flow in the air inlet pipe 47, so that a stable low-pressure environment is formed inside the buffer chamber 40, the drying chamber 41 and the heat exchange chamber 42;

[0054] At the same time, the double-head circulation motor 12 starts to work and controls the electromagnetic clutch 13 at the softened water impeller 11 to work, so that the double-head circulation motor 12 drives the softened water impeller 11 to work, so that the softened water enters the softened water outlet pipe 5 from one of the softened water tanks 4, enters the serpentine fin tube 45 through the softened water outlet pipe 5, and then enters the softened water inlet pipe 6 through the serpentine fin tube 45, so that the softened water enters the other softened water tank 4, and then flows back to the original softened water tank 4 through the softened water vacuum collector pipe 2, thereby forming a softened water tank 4. The circulation route of softened water is shown in FIG. 4 . During the circulation process, the softened water dissipates heat through the serpentine fin tube 45. The air in the air outlet pipe 49 enters the buffer chamber 40 through the high pressure in the air compression tank 46 and is buffered by the space in the buffer chamber 40. After the air velocity is reduced, the air enters between the two fin tube fixing plates 44 in the heat exchange chamber 42. The air flushes the serpentine fin tube 45 and dissipates heat through the serpentine fin tube 45, thereby heating the air and allowing the heated air to enter the drying chamber 41.

[0055] After the hot air enters the drying chamber 41, the building materials are heated. Since the air pressure inside the drying chamber 41 is relatively low, the evaporation temperature of water is reduced, so that the moisture in the building materials can evaporate quickly. The evaporated moisture enters the drying inlet pipe 54 along with the flow of air, and then enters the fixed box 52, and then enters the desiccant box 57 through the mesh holes on the mesh panels on both sides of the desiccant box 57, so that the hot air containing water vapor contacts the regenerable desiccant 58, and the regenerable desiccant 58 absorbs the moisture in the hot air, so that the hot air after the moisture is removed enters the fixed box 52 again, and enters another fixed box 52 through the connecting pipe 53, and then enters the air inlet pipe 47, and the hot air circulates through the operation of the vacuum pump 48, so that the building materials are fully dried.

[0056] During the drying process of building materials, when the temperature of the softened water is lower than the set value, the driving motor 24 at the softened water vacuum heat collecting tube 2 is controlled to work, so that the arc reflector 17 is lowered, so that the softened water vacuum heat collecting tube 2 is irradiated by sunlight again, so as to heat the softened water again, thereby ensuring that the serpentine fin tube 5 can always dissipate heat when the building materials are dried, and ensuring the stability of the air temperature when the building materials are dried;

[0057] When the building materials are dried, the vacuum pump 48 is controlled to stop working, and the high-pressure air in the air compression tank 46 is discharged from the air outlet pipe 49 by its own pressure, so that the air pressure in the buffer chamber 40, the drying chamber 41 and the heat exchange chamber 42 is restored to normal pressure. At the same time, the double-head circulation motor 12 and the electromagnetic clutch 13 are controlled to stop working, so that the softening water impeller 7 stops rotating and the entire device stops working. At this time, the staff can manually open the sealing door 73 to take out the dried building materials;

[0058] After the dried building materials are taken out, the staff closes the sealing door 73, and at this time, all the sealing electric telescopic rods 74 are controlled to start to shrink, so that the sealing electric telescopic rods 74 drive the ring square ladder sealing frame 65 to start to shrink through the cross frame 64, so that the ring square ladder sealing frame 65 is separated from the ring square groove 61 on the desiccant box 57. At this time, the electric telescopic rod 63 at the desiccant box 57 connected to the fixed box 52 is controlled to start to extend, and at the same time, the electric telescopic rod 63 at the desiccant box 57 connected to the evaporation tube 56 is controlled to start to shrink, so that the two fixed boxes 52 The desiccant boxes 57 in the first and second boxes 52 start to move. When the two desiccant boxes 57 move to the corresponding positions, the electric sealing telescopic rod 74 is controlled to start to extend, so that the ring square ladder-shaped sealing frame 65 is inserted into the ring square groove 61, so that the desiccant box 57 originally connected to the fixed box 52 is connected to the evaporation tube 56, and the desiccant box 57 originally connected to the evaporation tube 56 is connected to the fixed box 52, thereby completing the replacement of the desiccant box 57, so that the regenerable desiccant 58 in the desiccant box 57 can stably absorb moisture when the device is used to dry the building materials next time;

[0059] When the desiccant box 57 has finished moving, the regeneration sleeve 59 in the descending desiccant box 57 is separated from the heat transfer oil sleeve 68, and the regeneration sleeve 59 in the ascending desiccant box 57 is inserted into the heat transfer oil sleeve 68. At this time, the double-head circulation motor 12 is controlled to work, and the electromagnetic clutch 13 at the heat transfer oil impeller 11 is controlled to work, so that the double-head circulation motor 12 drives the heat transfer oil impeller 11 to rotate, so that the heat transfer oil enters the heat transfer oil outlet pipe 9 from one of the heat transfer oil boxes 8, and enters the lower pipe network 67, and then enters the heat transfer oil sleeve 68 through the lower pipe network 67. The heat transfer oil sleeve 68 and the thin heat transfer oil pipe 70 are limited and fixed by the positioning rod 71, so as to ensure the uniformity of the heat transfer oil flow in the heat transfer oil sleeve 68, so that the heat transfer oil can fully flow with the heat transfer oil sleeve 6 8, so that the heat-conducting oil sleeve 68 can dissipate heat evenly, the heat-conducting oil sleeve 68 heats the regeneration sleeve 59, thereby heating the regenerable desiccant 58 through the regeneration sleeve 59, so that the regenerable desiccant 58 is regenerated under the heating of the regeneration sleeve 59, and the heat-conducting oil enters the thin heat-conducting oil pipe 70 through the lower end of the heat-conducting oil sleeve 68, and then enters the upper pipe network 66 through the thin heat-conducting oil pipe 70, and then enters the heat-conducting oil inlet pipe 10 through the upper pipe network, and then enters another heat-conducting oil box 8, and then flows back to the original heat-conducting mailbox 8 through the heat-conducting oil vacuum heat collecting pipe 3, thereby completing the circulation route of the heat-conducting oil, and the regenerable desiccant 58 in the desiccant box 57 is regenerated through the circulation of the heat-conducting oil, so that the regenerable desiccant 58 can be circulated for use;

[0060] The desiccant box 57 is inserted into the annular square groove 61 through the annular square ladder sealing frame 65 and sealed by the sealing gasket 62, so as to ensure the sealing of the desiccant box 57 after it is moved. At the same time, the sealing between the annular square ladder sealing frame 65 and the fixed box 52 and the evaporation tube 56 is ensured by the highly sealed annular sealing gasket, so as to avoid the external air from entering the drying box 1 due to insufficient sealing, thereby affecting the gas circulation inside the drying box 1.

[0061] In the present device, the heat insulation plate 60 is arranged above the desiccant box 57 to prevent the temperature of the heat transfer oil in the heat transfer oil sleeve 68 from being too high and affecting the use of the regenerable desiccant 58 in the desiccant box 57. At the same time, the heat insulation plate 60 cooperates with the sealing gasket 62 to prevent high-temperature gas from entering the regeneration sleeve 59, thereby ensuring the temperature stability inside the desiccant box 57 and preventing the temperature inside the desiccant box 57 from changing due to the heat dissipation of the heat transfer oil, thereby affecting the use of the regenerable desiccant.

[0062] In this device, insulation materials can be arranged outside the softened water tank 4 and the thermal oil tank 8 to insulate the softened water tank 4 and the thermal oil tank 8, so as to prevent the softened water tank 4 and the thermal oil tank 8 from dissipating heat inside the drying box 1 and affecting the normal use of the drying box 1.

[0063] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
