[0021] As Figures 1 to 4 shown, this application provides a drying device for the waterproof construction base layer, including a moving mechanism (not shown in the figure), a first air outlet mechanism 1 and a second air outlet mechanism 2.

[0023] A waterproof construction base drying device provided by the present application can accelerate the air flow over a large range during the drying process by utilizing the high air volume characteristic of the axial flow fan 11 to accelerate the evaporation of accumulated water. At the same time, by utilizing the high wind pressure characteristic of the centrifugal fan 21, it can break the surface tension of the accumulated water, further accelerate the evaporation of the accumulated water, and enhance the penetration of the air flow, enabling the air flow to penetrate deep into the base, thereby squeezing the accumulated water in the pores of the base to the surface of the base. In addition, since the first included angle is greater than the second included angle, the air flows of the axial flow fan 11 and the centrifugal fan 21 can cross, thus forming a vortex on the surface of the base, which can also accelerate the evaporation of the accumulated water. In summary, with the cooperation of the axial flow fan 11 and the centrifugal fan 21, compared with the related art that only uses the axial flow fan 11, the drying efficiency is higher and the drying effect is better.

[0024] In a preferred embodiment of the present application, please refer to Figures 1 to 4 , the first air outlet mechanism 1 further includes a first frame 12 and a first driver 13.

[0025] With such a setting, according to the actual situation of the construction base, under the action of the first driver 13, the air outlet angle of the axial flow fan 11 can be adjusted, so as to control the air flow speed and impact force acting on the surface of the base by the axial flow fan 11, which helps to improve the drying efficiency and also helps to improve the drying effect.

[0026] Optionally, the first driver 13 is set as a reduction motor.

[0031] With such a setting, under the action of the horizontal rack 221, the distance between the vertical rack 222 and the centrifugal fan 21 can be increased, so as to facilitate the second driver 23 to drive the centrifugal fan 21 to rotate relative to the horizontal rack 221, and avoid the situation that the centrifugal fan 21 cannot rotate.

[0032] In a preferred embodiment of the present application, please refer to Figures 1 to 4 , the waterproof construction base drying device further includes an air inlet fan 3, a dehumidifying mechanism 4 and a dust removal mechanism 5.

[0033] With such a setting, in a dark and humid environment, through the dehumidifying mechanism 4, the air flow entering the axial flow fan 11 and the centrifugal fan 21 can be dehumidified, the environmental humidity can be reduced, so as to avoid the re-accumulation of water vapor on the surface of the base under the action of condensation, which helps to further enhance the drying effect. And, under the action of the dehumidifying mechanism 4, the axial flow fan 11 and the centrifugal fan 21 can be prevented from operating in a high-humidity environment, which helps to improve the service life of the axial flow fan 11 and the centrifugal fan 21. Under the action of the dust removal mechanism 5, the air flow entering the axial flow fan 11 and the centrifugal fan 21 can be dust-removed to avoid damage to the axial flow fan 11 and the centrifugal fan 21. And, during the drying process, a large amount of dust will be blown up by the drying device. Under the action of the dust removal mechanism 5, the dust entering the drying device can be collected to avoid the dust entering the construction site again and affecting the construction.

[0034] In a preferred embodiment of the present application, please refer to Figures 1 to 4 , the dehumidifying mechanism 4 includes a first channel 41, a second channel 42, a first switching valve 43, a second switching valve 44 and a dehumidifier 45.

The dehumidifier 45 is installed on the first channel 41 and located between the first switching valve 43 and the second channel 42.

[0035] With such a setting, during use, by controlling the on / off of the first switching valve 43 and the second switching valve 44, the air inlet fan 3 and the cyclone dust collector 51 can be connected through the first channel 41, the dehumidifier 45 can be connected to the air inlet channel, and the air flow entering the axial flow fan 11 and the centrifugal fan 21 can be dehumidified.

The air inlet fan 3 and the cyclone dust collector 51 can also be connected through the second channel 42, the dehumidifier 45 can be removed from the air inlet channel, and the air flow can enter the axial flow fan 11 and the centrifugal fan 21 without passing through the dehumidifier. In summary, with the cooperation of the first switching valve 43 and the second switching valve 44, it is possible to select whether to turn on the dehumidifier 45 according to the actual situation. Under the condition of not requiring dehumidification, the damage of the dehumidifier 45 caused by the air flow passing through the dehumidifier 45 can be avoided, effectively protecting the dehumidifier 45.

[0036] Optionally, both the first switching valve 43 and the second switching valve 44 are set as butterfly valves.

[0037] In a preferred embodiment of the present application, refer to Figures 1 to 4 , the dehumidifier 45 includes a housing 451, a compressor 452, a condenser 453 and an evaporator 454. The housing 451 is installed between the first switching valve 43 and the second channel 42. The compressor 452 is installed in the housing 451. Both the condenser 453 and the evaporator 454 are installed in the housing 451 and are both connected to the compressor 452.

[0038] With such a setting, under the action of the evaporator 454, the water vapor in the air flow can be condensed, thereby achieving the purpose of dehumidification. Under the action of the condenser 453, the temperature of the air flow can be increased, and the appearance of condensed water on the surface of the base layer caused by the cold air blown out by the axial flow fan 11 and the centrifugal fan 21 can be avoided.

[0039] In a preferred embodiment of the present application, please refer to Figures 1 to 4 , the dust removal mechanism 5 includes a cyclone dust collector 51, an elbow pipe 52 and a tee pipe 53. The cyclone dust collector 51 is installed on the dehumidification mechanism 4. The elbow pipe 52 is installed on the dehumidification mechanism 4. The first end of the tee pipe 53 is installed at the end of the elbow pipe 52 away from the cyclone dust collector 51. The second end of the tee pipe 53 is connected to the axial flow fan 11, and the third end of the tee pipe 53 is connected to the centrifugal fan 21.

[0040] With such a setting, under the action of the cyclone dust collector 51, the air flow entering the drying device can be dust-removed. Through the elbow pipe 52, the layout mode of the axial flow fan 11 and the centrifugal fan 21 can be changed, making the overall structure more compact and greatly improving the use convenience of the device. Under the action of the tee pipe 53, the cyclone dust collector 51 can be simultaneously connected to the axial flow fan 11 and the centrifugal fan 21.

When adjusting the angle of the centrifugal fan 21, through the second hose 55, it is possible to prevent the tee pipe 53 from interfering with the rotation of the centrifugal fan 21, ensure that the centrifugal fan 21 can rotate normally, and also enable the air flow to enter the centrifugal fan 21 normally.

[0043] In a preferred embodiment of the present application, refer to Figures 1 to 4 together. The distance between the axial flow fan 11 and the base layer is greater than the distance between the centrifugal fan 21 and the base layer.

[0044] With such a setting, it is possible to mix the air flow of the axial flow fan 11 and the air flow of the centrifugal fan 21, so as to generate a vortex on the surface of the base layer and improve the drying efficiency.

[0045] The working principle of a waterproof construction base layer drying device provided by the present application is as follows: The construction worker moves the device to the position to be dried through the moving mechanism. Before drying, the construction worker determines whether to turn on the dehumidification mechanism 4 according to the on-site situation. When it is necessary to turn on the dehumidification mechanism 4, the construction worker opens the first switching valve 43 and closes the second switching valve 44. At this time, the first channel 41 communicates the intake fan 3 and the cyclone dust collector 51, and finally turns on the dehumidifier 45. When it is not necessary to turn on the dehumidification mechanism 4, the construction worker closes the first switching valve 43 and opens the second switching valve 44. At this time, the second channel 42 communicates the intake fan 3 and the cyclone dust collector 51. During the drying process, the intake fan 3 sends the air flow into the cyclone dust collector 51 through the first channel 41 or the second channel 42. The cyclone dust collector 51 removes the impurities and dust in the air flow and outputs the air flow to the elbow pipe 52. The air flow reaches the tee pipe 53 through the elbow pipe 52. Under the action of the tee pipe 53, the air flow is respectively conveyed to the axial flow fan 11 and the centrifugal fan 21 and is output through the axial flow fan 11 and the centrifugal fan 21.

[0046] When the dehumidification mechanism 4 is turned on, the compressor 452 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gas, and sends the high-temperature and high-pressure gas into the condenser 453. The condenser 453 dissipates heat and heats the dry and cold air flow into a dry and hot air flow. The high-temperature and high-pressure gas is liquefied into a high-pressure liquid through heat dissipation, and is throttled by the expansion valve to become a low-temperature and low-pressure liquid, and enters the evaporator 454. The evaporator 454 absorbs heat and condenses the water vapor in the air flow to achieve the purpose of dehumidification. In the evaporator 454, the refrigerant absorbs heat and evaporates into a low-temperature and low-pressure gas, and returns to the compressor 452, repeating the cycle.
