Preferably, the front end of the condensation drying unit is further provided with a pressure relief valve, and the rear end of the pressure relief valve is provided with a pressure sensor. The limitation is such that when the pressure sensor detects that the pressure after the relief valve relieves the pressure exceeds a set value, a part of the pressure is released by the front end relief valve.
Preferably, an air filter is arranged at the front end of the fan. The limitation ensures that the air sent into the enclosed bus is clean and plays a role of dust prevention.
Preferably, the rain-proof door, the rain-proof top and the pipeline joint of the hot air device are all made of stainless steel. The above definition ensures that the equipment can play a role of rain prevention when being installed outdoors, thereby preventing the shell of the equipment from being rusted.
The utility model discloses a set for moisture and discharge in the condensation drying unit can the deaerate, rethread heating unit heaies up the air for the air of sending into enclosed bus can satisfy the requirement of drying under the uniform temperature, thereby improve equipment's life.
Drawings
Fig. 1 is a schematic structural view of an embodiment of a hot air device of the present invention.
The notation in the figure is: the method comprises the following steps of 1-air filter, 2-fan, 3-pressure release valve, 4-pressure sensor, 5-condensation drying unit, 6-temperature and humidity sensor, 7-heating unit and 8-closed bus.
Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1, the present embodiment provides a hot air device, which includes a fan 2 and a closed bus 8 (sealed bus), wherein the fan 2 is configured to send hot air to the closed bus 8, in order to remove moisture in air, a condensation drying unit 5 is disposed between the fan 2 and the closed bus 8, the condensation drying unit 5 has a water outlet, and condenses air through the condensation drying unit 5, so as to discharge moisture, a temperature and humidity sensor 6 is disposed at a rear end of the condensation drying unit 5 and is configured to detect a temperature and humidity of the air processed by the condensation drying unit 5, and a heating unit 7 is disposed between the temperature and humidity sensor 6 and the closed bus 8 to heat the air, so that the air meets an air supply temperature requirement of the closed bus 8.
In another embodiment, in consideration of the condition that the pressure of the wind sent by the fan 2 is too high, a pressure release valve 3 is arranged at the front end of the condensation drying unit 5, a pressure sensor 4 is arranged at the rear end of the pressure release valve 3, the pressure release valve 3 and the pressure sensor 4 work cooperatively, when the pressure sensor 4 detects that the pressure relieved by the pressure release valve 3 exceeds a set value, part of the pressure is released through the pressure release valve 3, the pressure release valve 3 can be a pressure release protection valve, and in a specific implementation, the pressure release valve 3 is installed on an air outlet of the fan 2.
In another embodiment, in order to ensure the cleanness of the interior of the seal bus, the dust prevention of an air source is well performed, and the air filter 1 is arranged at the front end of the fan 2 to ensure the cleanness of the air sent into the seal bus 8. The air filter 1 is arranged at the inlet of the fan 2 and can be cleaned and replaced periodically.
Because hot air device all installs the open air generally, for reaching rainproof purpose, avoid equipment housing to corrode ageing, this embodiment all adopts stainless steel with the position of the easy corrosion of capacities such as hot air device's rain-proof door, rain-proof top and pipeline joint.
The following brief description of the working principle of the present application: firstly, a fan 2 is turned on, outside air passes through an air filter 1 and then is fed into the fan 2, and then enters a condensation drying unit 5 through a pressure release valve 3, at the moment, if a pressure sensor 4 detects that the pressure exceeds a set value, the pressure release valve 3 can automatically release a part of air to reduce the air pressure and control the air inlet pressure, then the air passes through the condensation drying unit 5 to be dried and dewatered, so that the temperature is kept at about-4 ℃, and moisture in the air is automatically discharged out of the device through a water outlet; the dried air passes through the temperature and humidity sensor 6 and then is sent to the heating unit 7, and after heating and warming, dried and purified hot air with pressure of 3000 Pa-3500 Pa is filled into the enclosed bus 8, so that the insulation level of the enclosed bus 8 is improved.
