The profile drying apparatus in the preferred embodiment described above has various usage modes, specifically:
use mode 1: opening the third valve, closing the first valve and the second valve, and vacuumizing the interior of the first box by using a vacuum pump while heating the profile in the first box, so that negative pressure is formed in the first box, and positive pressure is formed in the second box; after the vacuum pump is started for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a first threshold), the first valve is opened, the air in the first accommodating space enters the first box body to generate air flow, the evaporation of water is accelerated, and the energy consumption of the heating device is further reduced; after the first valve is opened for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a second threshold), the first valve is closed; therefore, the first valve is repeatedly opened and closed, and in the whole process, the heat generated by the heating device can be recycled, so that the energy is greatly saved.
Use mode 2: opening the third valve, closing the first valve and the second valve, and vacuumizing the interior of the first box by using a vacuum pump while heating the profile in the first box, so that negative pressure is formed in the first box, and positive pressure is formed in the second box; after the vacuum pump is started for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a first threshold), the first valve is opened, the air in the first accommodating space enters the first box body to generate air flow, the evaporation of water is accelerated, and the energy consumption of the heating device is further reduced; after the first valve is opened for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a second threshold), the first valve is closed; thus forming a drying cycle; after one or more drying cycle processes, after the first valve is closed for a certain time or when the air pressure in the second box body reaches a certain value (also can be called a third threshold), the third valve and the vacuum pump are closed, the second valve is opened, and the air flows outwards from the second box body along the second vent pipe because the air pressure in the second box body is greater than the external air pressure; after the second valve is opened for a certain time or when the air pressure in the second box reaches a certain value (also referred to as a fourth threshold), the drying cycle is repeated, and the process is repeated. In the case of using this usage, the first accommodating space is preferably set to be much larger than the second accommodating space, for example, the first accommodating space is more than 4 times larger than the second accommodating space.
Use mode 3: opening the third valve and the second valve, closing the first valve, and vacuumizing the interior of the first box by using a vacuum pump while heating the profile in the first box to form negative pressure in the first box, wherein the negative pressure is generated in the first box in the process so as to reduce the boiling point of water and make the moisture on the surface of the profile easier to vaporize, so that the energy consumption of a heating device can be reduced, and the water vapor evaporated in the first box enters the second box through a connecting pipe and then is discharged through a second vent pipe in the process; after the vacuum pump is started for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a first threshold), the first valve is opened, the air in the first accommodating space enters the first box body to generate air flow, the evaporation of water is accelerated, and the energy consumption of the heating device is further reduced; after the first valve is opened for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a second threshold), the first valve is closed; therefore, the first valve is repeatedly opened and closed, and in the whole process, the heat generated by the heating device can be recycled, so that the energy is greatly saved.
Use mode 4: opening the third valve and the second valve, closing the first valve, and vacuumizing the interior of the first box by using a vacuum pump while heating the profile in the first box to form negative pressure in the first box, wherein the negative pressure is generated in the first box in the process so as to reduce the boiling point of water, so that the moisture on the surface of the profile is easier to vaporize, and the energy consumption of a heating device can be reduced; after the vacuum pump is started for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a first threshold), the first valve is opened, the air in the first accommodating space enters the first box body to generate air flow, the evaporation of water is accelerated, and the energy consumption of the heating device is further reduced; after the first valve is opened for a certain time or when the air pressure in the first box body reaches a certain value (also can be called a second threshold), the first valve is closed; this results in a drying cycle, after one or more drying cycles, the second valve is closed, after the second valve is closed for a certain time or when the air pressure in the second box body reaches a certain value (also can be called a third threshold value), the third valve and the vacuum pump are closed, the second valve is opened, because the internal gas pressure of the second box body is higher than the external gas pressure, the gas flows outwards from the second box body along the second vent pipe, in the process, along with the discharge of the gas, the gas in the first accommodating space enters the second accommodating space through the filtering structure and then is discharged through the second vent pipe, in the process, the drying gas in the first accommodating space reversely moves and takes away part of moisture absorbed by the filtering structure when passing through the filtering structure, so that the service life of the filtering structure is prolonged, and the vacuum pump does not continuously work for a long time and is not easy to damage; after the second valve is opened for a certain time or when the air pressure in the second box reaches a certain value (also referred to as a fourth threshold), the drying cycle is repeated, and the process is repeated.
In practical production, the volume of the second box body can be set to be smaller than that of the first box body, generally, the volume of the second box body can be one fifth or smaller than that of the first box body, and a plurality of isolation nets 19 are arranged inside the first box body, so that the profiles can be arranged in the first box body in order.
The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
