Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Depend on Figure 1-5 The present invention relates to a drying device for painting I-beams, including a spray booth 3, with inlet and outlet ports at both ends of the spray booth 3, and roller doors 4 installed on the top of the inlet and outlet ports of the spray booth 3, and a drying and heating component 6 installed on the inner wall of the spray booth 3.

[0026] The drying and heating assembly 6 includes an air heating unit 601 installed on the inner walls of both sides of the spray booth 3, and an internal heating unit 602 is provided on both sides of the air heating unit 601.

[0027] The internal heating unit 602 includes n-shaped tubes 6022 that are equidistantly arranged on both sides of the air heating unit 601. Each n-shaped tube 6022 consists of two longitudinal tubes and one transverse tube. The two longitudinal tubes are installed on the inner walls of both sides of the spray booth 3, and the transverse tube is installed on the inner top wall of the spray booth 3. A connecting tube 6023 is installed equidistantly between the longitudinal tubes of two adjacent n-shaped tubes 6022. The two closest n-shaped tubes 6022 on both sides of the air heating unit 601 have end tubes 6021 installed on one side of each other. A switch valve unit 603 is installed on the transverse tube.

[0028] The air heating unit 601 includes two air inlet cylinders 6011 fixedly installed on the inner walls of both sides of the spray booth 3. A heating cylinder 6014 is located on the side of the air inlet cylinder 6011 closest to the inner cavity of the spray booth 3. A partition cylinder 6015 is coaxially installed inside the heating cylinder 6014. A second through hole 6017 is circumferentially located at the end of the partition cylinder 6015 furthest from the air inlet cylinder 6011. Heating coils 6018 are installed on both the inner and outer walls of the partition cylinder 6015. Two end tubes 6021 are... The heating cylinder 6014 is connected to both sides of the end near the air inlet cylinder 6011. The end of the air inlet cylinder 6011 away from the heating cylinder 6014 has evenly spaced air inlets 6012. The air inlets 6012 are connected to the external environment of the paint booth 3. A fan 6013 is installed inside the air inlet cylinder 6011. A first through hole 6016 is opened on the side of the air inlet cylinder 6011 near the heating cylinder 6014. The first through hole 6016 extends into the interior of the partition cylinder 6015.

[0029] The switching valve unit 603 includes a bottom pipe 6031 fixedly installed at the bottom end of the transverse pipe of the n-shaped pipe 6022. A baffle 6032 is provided below the bottom pipe 6031. The heating coil 6018 is energized to heat the air. Driven by the fan 6013, the hot air is pushed into the n-shaped pipe 6022 and the connecting pipe 6023 to facilitate heating of the inner cavity of the paint booth 3, thereby facilitating the drying of the painted H-beams. At the same time, the baffle 6032 moves downward to facilitate the introduction and discharge of cold air into the paint booth 3. The top wall of the baffle 6032 is in close contact with the bottom wall of the bottom pipe 6031. A fixed cylinder 6033 is fixedly installed at the top of the n-shaped pipe 6022. A movable block 6034 is movably installed inside the fixed cylinder 6033. A connecting rod 6035 is fixedly installed at the bottom of the movable block 6034. The bottom end of the connecting rod 6035 is fixedly connected to the baffle 6032. A spring 6036 is fixedly installed at the bottom of the movable block 6034. The bottom end of the spring 6036 is fixedly connected to the inner bottom wall of the fixed cylinder 6033. A magnetic block 6037 is installed on the movable block 6034. An electromagnet 6038 is installed at the top of the fixed cylinder 6033. When the electromagnet 6038 is energized, it attracts the magnetic block 6037, causing the baffle 6032 to press tightly against the bottom end of the bottom tube 6031. This prevents hot air from escaping from the inside of the n-shaped tube 6022 and the connecting tube 6023, thus insulating the inner cavity of the paint booth 3. At the same time, it can shut off the heating coil 6018, achieving energy saving.

[0030] The spray booth 3 is located above the base plate 1. The top of the base plate 1 is symmetrically equipped with a sliding groove 2. The bottom of the spray booth 3 is slidably connected to the sliding groove 2. A support frame 5 is provided on the base plate 1.

[0031] Working principle: During operation, the I-beam to be painted is placed on the support frame 5, and then the paint booth 3 is moved along the slide 2 to the outside of the support frame 5. Then, the two roller doors 4 at both ends of the paint booth 3 are pulled down to close the paint booth 3. Then, the paint equipment inside the paint booth 3 is used to paint the I-beam.

[0032] After the painting is completed, the H-beam needs to be dried. First, the heating coil 6018 is energized, so that the heating coil 6018 heats up and can heat the inside of the heating cylinder 6014. Then, the fan 6013 is turned on, pushing the air inside the heating cylinder 6014 to continuously enter the n-shaped tube 6022 and the connecting tube 6023. Under the action of air pressure, the baffle 6032 is exerted downward pressure, pushing the baffle 6032 to move downward and open the bottom tube 6031, thereby expelling the cold air inside the n-shaped tube 6022 and the connecting tube 6023, so that the n-shaped tube 6022 and the connecting tube 6023 are filled with hot air, thereby raising the temperature inside the paint booth 3, which can dry the paint on the surface of the H-beam.

[0033] When the internal temperature of the spray booth 3 rises, it is necessary to keep the interior of the spray booth 3 warm. At this time, the electromagnet 6038 is energized to attract the magnetic block 6037 and generate an upward pulling force on the magnetic block 6037, so that the baffle 6032 and the bottom tube 6031 are sealed, so that the hot air that has entered the n-shaped tube 6022 and the connecting tube 6023 will not enter the inner cavity of the spray booth 3. At this time, the heating coil 6018 can be turned off, which has an energy-saving effect.
