Description

Technical Field

[0001] The utility model relates to the technical field of heating and dehumidifying devices for water-based paint drying rooms, and specifically relates to a heating and dehumidifying device for a water-based paint drying room. Background Technique

[0002] Water-based paint only has primer and topcoat. Currently, only solvent-based paint can be used for varnish, and water-based varnish has not been developed yet. Solvent-based paint can be processed by the wet-on-wet process. When processing water-based paint, it needs to be heated and dehumidified through a drying room. When the water-based paint workpiece is dehumidified and heated, volatile organic compounds (VOCs) and other harmful gases may be generated, which will then pollute the inside of the device. At the same time, when the drying room is drying and dehumidifying the water-based paint workpiece, some waste gas particles may be generated, which will then adhere to the inside of the heating and dehumidifying device, thus affecting the operation of the device and reducing the use effect of the device. In addition, when the heating and dehumidifying device is in use, it will directly spray out air flow, and the air flow may directly impact the outside of the workpiece, which may then affect the workpiece through the impact force and reduce the quality of the finished product after processing.

Detailed Description of the Preferred Embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a technical solution. Please refer to Figure 1 and Figure 2, A heating and dehumidifying device for an aqueous paint drying chamber, comprising: a combustion chamber 1, a burner 2, a first fan 3, a second fan 4, a square pipe 5 and a heat preservation pipe 6. The combustion chamber 1 is connected by two flange plates, and the combustion chamber 1 can be disassembled for maintaining and cleaning the internal components. The first fan 3 can suck the exhaust gas of the drying chamber into the interior of the combustion chamber 1. The burner 2 can ignite the purified exhaust gas. The second fan 4 can suck the purified exhaust gas into the interior of the square pipe 5. The square pipe 5 and the heat preservation pipe 6 can re-discharge the purified and heated exhaust gas into the interior of the drying chamber to complete drying and dehumidification.

[0023] Please refer to Figure 3 , The burner 2 is installed at the bottom of the inner cavity of the combustion chamber 1. The first fan 3 is connected to the left side of the combustion chamber 1. The second fan 4 is connected to the top right side of the combustion chamber 1. The square pipe 5 is connected to the air outlet of the second fan 4. A sloping plate 51 is connected to the inner back surface of the square pipe 5. The top and bottom of the sloping plate 51 are hermetically connected to the square pipe 5. The sloping plate 51 can divert the airflow sucked by the second fan 4. The heat preservation pipe 6 is connected to the right side of the square pipe 5. The heat preservation pipe 6 is a long pipe made of glass fiber, and a nozzle is connected to the right side of the heat preservation pipe 6 through a flange plate. The heat preservation pipe 6 can be connected in multiple groups through flange plates, thereby changing the overall length of the heat preservation pipe 6.

[0024] Please refer to Figure 4 , A friction mechanism 7 is installed at the inner top of the combustion chamber 1. The friction mechanism 7 includes a vane runner 71. Vanes are connected to the outside of the vane runner 71 at equal intervals. The vane runner 71 can be driven by the airflow in cooperation with the vanes. At the same time, the bottom of the vane runner 71 can also be connected to a motor for driving, thereby improving the overall diversity of the device. The bottom of the vane runner 71 is connected to the bottom of the square pipe 5 through a pedestal bearing.

[0025] A first short shaft 72 is fixedly connected to the top of the vane runner 71. The first short shaft 72 can drive a second short shaft 75 through the cooperation of a sprocket 74 and a chain belt 73. The chain belt 73 is installed on the outside of the first short shaft 72. The other end of the chain belt 73 is installed with the second short shaft 75. Spherical bearings 751 are sleeved on the outside of the first short shaft 72 and the second short shaft 75. The two spherical bearings 751 are respectively embedded and connected to the top of the square pipe 5 and the combustion chamber 1. The spherical bearings 751 can support the first short shaft 72 and the second short shaft 75.

[0026] The tops of the second minor axis 75 and the first minor axis 72 are both sleeved with sprockets 74. The outsides of the two sprockets 74 are connected to the inside of the chain belt 73. The bottom of the second minor axis 75 is connected with first friction plates 76 at equal intervals. The first friction plates 76 and the second friction plates 77 can clean the inner wall of the combustion chamber 1 through friction. The outside of the first friction plates 76 is fixedly connected with the second friction plates 77. The inner wall of the combustion chamber 1 is provided with annular grooves 11. The inside of the annular grooves 11 is slidably connected with sliders 771 at equal intervals. The sliders 771 are connected to the second friction plates 77. The annular grooves 11 and the sliders 771 can make the second friction plates 77 always close to the inner wall of the combustion chamber 1.

[0027] Please refer to Figure 5 , a collection box 8 is connected to the inside of the combustion chamber 1 by bolts. The top of the collection box 8 is fixedly connected with a diversion slope 81. The collection box 8 can be disassembled and maintained by means of bolt connection. The diversion slope 81 is designed with a higher outside and a lower inside. The outside of the diversion slope 81 is in close contact with the inside of the combustion chamber 1. Then all the dust cleaned by the friction mechanism 7 falls into the inside of the collection box 8 through the diversion slope 81.

[0028] In this solution, first, the combustion chamber 1 is installed inside the drying chamber. The length of the heat preservation pipe 6 is changed so that the heat preservation pipe 6 is far away from the first blower 3 and the heat preservation pipe 6 is communicated with the drying chamber. The first blower 3 and the burner 2 are started to inhale the waste gas inside the drying chamber, and then the waste gas is burned and purified by the burner 2. The waste gas is decomposed into carbon dioxide and steam. The heated and purified waste gas is then discharged into the inside of the drying chamber through the cooperation of the second blower 4, the square pipe 5 and the heat preservation pipe 6, thereby realizing the drying and dehumidification of the gas inside the drying chamber;

[0029] When the gas treated by combustion enters the inside of the square pipe 5, it will drive the blade wheel 71 to rotate. Then, through the cooperation of the first minor axis 72 and the chain belt 73, the second minor axis 75 is driven to rotate. Then, the inner wall of the combustion chamber 1 is scraped and cleaned by the rotation of the first friction plates 76 and the second friction plates 77, avoiding that when the waste gas of the water-based paint is burned, the particles inside may adhere to the inner wall of the combustion chamber 1;

[0030] When the second friction plates 77 clean the inner wall of the combustion chamber 1, they will also intermittently block the air inlet of the second blower 4, avoiding that the second blower 4 continuously inhales and discharges the gas, and then continuously discharging the gas directly to the workpiece;

[0031] When the water-based paint drying chamber dehumidifies and heats the internal gas, through the added burner 2, second fan 4, square pipe 5 and heat preservation pipe 6, the gas is automatically purified, thus avoiding the accumulation of water-based paint inside the drying chamber. At the same time, the heat after the waste gas combustion is automatically recovered to heat and dehumidify the drying chamber, thereby reducing energy consumption. Also, through the added friction mechanism 7, the flow force of the air flow is automatically recovered to clean the inner wall of the combustion chamber 1, avoiding that the particles inside may adhere to the inner wall of the combustion chamber 1 when the waste gas of the water-based paint is burned, and at the same time intermittently blocking the heated and discharged air flow to reduce the impact force generated when the air flow enters the inside of the drying chamber.
