Description

Technical Field

[0001] This utility model relates to the field of water-based coating drying technology, and in particular to a water-based coating hot air circulation box. Background Technology

[0002] Water-based coating drying refers to the process by which water in water-based coatings is evaporated or absorbed through physical or chemical action, thereby transforming the coating from a liquid state into a solid paint film. A water-based coating hot air circulation box is a special equipment designed specifically for drying water-based coatings. Its core function is to provide a controllable drying environment for water-based coatings through the synergistic effect of heating and air circulation systems, so as to promote the efficient evaporation of water in the coating and the formation of a uniform paint film.

[0003] Existing water-based coating drying equipment suffers from low hot air circulation efficiency, resulting in significant heat waste, high energy consumption, and high drying costs. Furthermore, uneven hot air distribution within the drying chamber leads to inconsistent drying levels in different areas of the water-based coating, negatively impacting coating quality. Utility Model Content

[0004] The purpose of this invention is to provide a hot air circulation box for water-based coatings, which solves the problem that existing water-based coating drying equipment is not convenient for circulating hot air.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water-based coating hot air circulation box, including a box body;

[0006] A door is installed on one side of the box body, and a circulation structure is fixed to the top of the box body. The circulation structure includes a hot air box fixed to one side of the top of the box body, a heating wire installed inside the hot air box, an end cap installed at the top of the hot air box, an air outlet box fixed to the top of the inside of the box body, a through groove provided in the middle of the air outlet box, an air outlet pipe fixed to the bottom of the air outlet box, a filter box fixed to one side of the bottom of the box body, a box cover installed at the top of the filter box, a filter plate provided inside the filter box, a circulation pump fixed to one side of the box body, a connecting pipe installed at one end of the circulation pump, an air inlet pipe installed at the other end of the circulation pump, and an exhaust pipe fixed to one side of the bottom of the filter box.

[0007] The interior of the chamber is equipped with a stirring structure.

[0008] Preferably, a fan is installed at the top of the hot air box, an end cover is installed at the air inlet of the fan, an air supply pipe is fixed at the bottom of the hot air box, one end of the air supply pipe extends through the top of the air outlet box to the interior of the air outlet box, and the air outlet pipes are evenly distributed at the bottom of the air outlet box.

[0009] With the above structure, during use, the fan draws outside air into the hot air box, providing a sufficient air source for the subsequent heating and air supply process. This ensures that hot air can be continuously generated and delivered into the box. The end cap installed at the fan inlet can guide and regulate the air intake, allowing the circulating air to enter the hot air box more evenly, which helps to improve heating efficiency and the stability of the hot air.

[0010] Preferably, the filter plate is an activated carbon filter plate, and the filter plates are evenly distributed inside the filter box. Valves are installed on the outside of the connecting pipe and the air inlet pipe.

[0011] With the above structure, the filter plate adopts activated carbon filter plate during use. Utilizing the strong adsorption capacity of activated carbon, it can effectively remove impurities such as paint volatiles, dust, and water vapor carried by the hot air during circulation, as well as odors generated during the drying process. In addition, the circulation flow rate of the hot air can be flexibly adjusted according to the actual drying needs through the valves installed on the outside of the connecting pipe and the air inlet pipe.

[0012] Preferably, one end of the connecting pipe extends through one side of the filter box into the interior of the filter box, and one end of the air inlet pipe extends through one side of the hot air box into the interior of the hot air box.

[0013] With the above structure, during use, one end of the connecting pipe penetrates through the side wall of the filter box and extends into its interior, allowing direct contact with the filtered hot air. This quickly extracts the purified hot air from the filter box, enabling the recovered hot air to directly enter the hot air box through the air inlet pipe and be reheated to the required temperature by the heating wire.

[0014] Preferably, the stirring structure includes a placement groove located at the bottom of the interior of the housing, a placement box placed inside the placement groove, a motor fixed to the other side of the top of the housing, a rotating shaft fixed to the output end of the motor, a driving gear fixed to the bottom of the rotating shaft, a driven gear mounted on one side of the driving gear, a threaded rod fixed to the bottom of the driven gear, a threaded cylinder mounted on the outside of the threaded rod inside the housing, a fixing block fixed to the bottom of the threaded cylinder, a rotating frame fixed to the outside of the fixing block, and a stirring rod fixed to one side of the rotating frame.

[0015] Preferably, the placement box is fitted into the placement slot, the driving gear and the driven gear are meshed, and the bottom end of the threaded rod extends through the top of the box and into the interior of the box.

[0016] With the above structure, the placement box fits into the placement slot during use. This design allows the placement box to be accurately positioned inside the box. The driving gear and the driven gear are meshed. When the motor drives the shaft to rotate, the driving gear rotates accordingly and drives the driven gear to rotate through the meshing relationship.

[0017] Preferably, the threaded cylinder and the threaded rod are threadedly connected, the rotating frame is arranged in an "L" shape, one side of the rotating frame abuts against the inner wall of the placement box, and a silicone pad is fixed on one side of the rotating frame.

[0018] With the above structure, the rotating frame can be raised and lowered by rotating the threaded cylinder during use. Before drying, the rotating frame can be lowered by rotating the threaded cylinder to extend into the placement box; after drying, the rotating frame can be raised to facilitate the removal of the placement box.

[0019] Preferably, the rotating frame is evenly distributed on the outside of the fixed block, and the stirring rod is evenly distributed on one side of the rotating frame.

[0020] With the above structure, the rotating frame is evenly distributed around the fixed block during use. When the rotating frame rotates, it ensures that the paint in each area of ​​the box is evenly stirred by the stirring rod, avoiding blind spots in the stirring process.

[0021] The advantages of the hot air circulation box for water-based coatings provided by this utility model are as follows:

[0022] By incorporating a circulation structure, a circulating pump can recycle and reuse the hot air inside the chamber, preventing heat waste. The hot air is filtered through an activated carbon filter and then reheated for reuse, reducing energy consumption and lowering drying costs.

[0023] The system features a stirring structure that uses a rotating screw cylinder to raise and lower a rotating frame, allowing the frame to be easily moved out of the placement box. This facilitates the removal and placement of the placement box. The stirring rod agitates the water-based coating, resulting in more uniform heating and accelerating the drying process, thus shortening the drying time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 The present invention provides a hot air circulation box for water-based coatings, comprising a box body 1.

[0032] Reference Figures 1-4As shown, a door 2 is installed on one side of the housing 1, and a circulation structure 3 is fixed to the top of the housing 1. The circulation structure 3 includes a hot air box 301 fixed to one side of the top of the housing 1, a heating wire 302 installed inside the hot air box 301, an end cap 303 installed at the top of the hot air box 301, an air outlet box 304 fixed to the top inside the housing 1, a through groove 305 provided in the middle of the air outlet box 304, an air outlet pipe 306 fixed to the bottom of the air outlet box 304, a filter box 307 fixed to one side of the bottom of the housing 1, a cover 308 installed at the top of the filter box 307, a filter plate 309 provided inside the filter box 307, a circulation pump 310 fixed to one side of the housing 1, a connecting pipe 311 installed at one end of the circulation pump 310, and a connecting pipe 311 installed at the other end of the circulation pump 310. The filter box 307 is equipped with an air inlet pipe 312. An exhaust pipe 313 is fixed to one side of the bottom of the filter box 307. A fan is installed at the top of the hot air box 301. An end cover 303 is installed at the air inlet of the fan. An air supply pipe is fixed at the bottom of the hot air box 301. One end of the air supply pipe passes through the top of the air outlet box 304 and extends into the interior of the air outlet box 304. Air outlet pipes 306 are evenly distributed at the bottom of the air outlet box 304. The filter plate 309 is an activated carbon filter plate. The filter plates 309 are evenly distributed inside the filter box 307. Valves are installed on the outside of the connecting pipe 311 and the air inlet pipe 312. One end of the connecting pipe 311 passes through one side of the filter box 307 and extends into the interior of the filter box 307. One end of the air inlet pipe 312 passes through one side of the hot air box 301 and extends into the interior of the hot air box 301.

[0033] Air is drawn in by starting the fan, heated by the heating wire 302, and then delivered to the outlet box 304 through the air duct. The hot air is evenly distributed after entering the outlet box 304, and then blown into the interior of the chamber 1 through the evenly spaced outlet pipes 306 at the bottom of the outlet box 304 to heat and dry the water-based coating. The hot air inside the chamber 1 is drawn into the filter box 307 through the exhaust pipe 313. The activated carbon filter plates 309, evenly spaced inside the filter box 307, filter the recovered hot air. The system adsorbs impurities and odors, purifies the air, and starts the circulation pump 310 to draw the filtered hot air from the filter box 307 through the connecting pipe 311. The air is then sent back to the hot air box 301 through the air inlet pipe 312 for reheating and reuse. At the same time, the top of the hot air box 301 is sealed by the end cover 303, so that the hot air inside the box 1 can be circulated by the circulation pump 310. The circulation flow rate of the hot air can be controlled by the valves on the outside of the connecting pipe 311 and the air inlet pipe 312.

[0034] Reference Figures 2-5As shown, a stirring structure 4 is installed inside the housing 1. The stirring structure 4 includes a placement groove 401 located at the bottom of the housing 1, inside which a placement box 402 is placed. A motor 403 is fixed to the other side of the top of the housing 1. A rotating shaft 404 is fixed to the output end of the motor 403. A drive gear 405 is fixed to the bottom end of the rotating shaft 404. A driven gear 406 is installed on one side of the drive gear 405.
