Description

Technical Field

[0001] This utility model mainly relates to the field of explosion-proof drying ovens, specifically to an air distribution guide plate structure for an explosion-proof drying oven. Background Technology

[0002] Explosion-proof drying ovens are core equipment widely used in chemical, pharmaceutical, electronics, and military industries. They are used to safely and efficiently dry materials in high-temperature environments where flammable and explosive gases may be present. Under these harsh operating conditions, the uniformity of the temperature field and the stability of the airflow organization within the working area of ​​the drying oven are crucial to ensuring product quality, improving drying efficiency, and ensuring the explosion-proof safety of the equipment.

[0003] To achieve uniform airflow distribution within the enclosure, existing technologies typically incorporate baffles or air distribution plates on the inner wall of the enclosure. A common approach involves installing a set of valve-controlled ducts at the supply or return air channels of the enclosure, with baffles installed inside or at the outlet of these ducts to guide and distribute the airflow.

[0004] However, the inventors of this application have discovered through long-term research and practice that this structure of "using a single valve pipe in conjunction with a set of guide plates" has a significant technical defect: when the airflow passes through the structure, it is very easy to form harmful vortices inside it.

[0005] The generation of this vortex mainly stems from the following aspects: Structural abrupt changes and spatial constraints: The opening and closing of the valve itself alters the diameter and shape of the flow channel. When airflow enters or exits the confined valve pipe from the relatively open box space, the abrupt change in the flow channel cross-section leads to boundary layer separation. This separation phenomenon is particularly pronounced within the limited space of the baffle plate, where it cannot be fully developed or effectively suppressed, thus evolving into a stable vortex region.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

A first sealing plate is slidably connected to the inner wall of the diversion port. A second sealing plate is provided on one side of the first sealing plate. A positioning shaft is provided between the second sealing plate and the first sealing plate. The second sealing plate and the first sealing plate are rotatably connected through the positioning shaft. The second sealing plate is rotatably connected to the inner wall of the diversion port.

[0014] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This invention utilizes multiple guide tubes that work together to allow external gas to be discharged through the guide tubes. When the guide tubes need to be closed, the first sealing plate and the second sealing plate rotate relative to each other and overlap to seal the guide tube to be closed. At the same time, the gas inside the guide tube enters the interior of another guide tube through the opened diversion port and is discharged, thus preventing gas from entering the guide tube and causing eddies that would affect the stability of gas discharge.

[0021] See attached document Figure 1-4 An air distribution guide plate structure for an explosion-proof drying box includes an air distribution chamber structure 1, a flow diversion structure 2 is provided on the top of the air distribution chamber structure 1, and a pipe structure 3 is provided inside the air distribution chamber structure 1. Pipeline structure 3 includes an air guide pipe 301. A diversion port 303 is formed on the outer wall of the air guide pipe 301. A first sealing plate 304 is slidably connected to the inner wall of the diversion port 303. A second sealing plate 305 is provided on one side of the first sealing plate 304. A positioning shaft 306 is provided between the second sealing plate 305 and the first sealing plate 304. The second sealing plate 305 and the first sealing plate 304 are rotatably connected via the positioning shaft 306. The second sealing plate 305 is rotatably connected to the inner wall of the diversion port 303. An electric push rod 307 is rotatably connected to one side of the first sealing plate 304. One end of the electric push rod 307 is connected to the air guide pipe 301. The number of air guide pipes 301 is set as follows: There are multiple gas guide pipes 301 stacked on top of each other. A connecting pipe 302 is provided at the top of each gas guide pipe 301. Gas enters the interior of the gas guide pipe 301 and is discharged through the connecting pipe 302. When it is necessary to independently close a single connecting pipe 302, the electric push rod 307 is activated. The electric push rod 307 drives the first sealing plate 304 to slide on the inner wall of the diversion port 303. The first sealing plate 304 drives the second sealing plate 305 to rotate through the positioning shaft 306. The first sealing plate 304 and the second sealing plate 305 seal the gas guide pipe 301 and open the diversion port 303. The gas entering through the gas guide pipe 301 enters the interior of another gas guide pipe 301 through the diversion port 303.

[0022] Furthermore, the flow guiding chamber structure 1 includes an installation chamber 101 with a placement chamber 102 inside. An air inlet 103 is provided on the outer wall of one side of the installation chamber 101. A guide plate 104 is provided on the top of the installation chamber 101. An installation hole 105 is provided inside the guide plate 104. The air inlet 103 is connected to a pipe. One end of the pipe is connected to an air pump for transporting gas. The gas enters the interior of the pipe structure 3 through the air inlet 103 and is discharged through the guide plate 104. The diversion structure 2 is used to guide the discharged gas.

[0023] Furthermore, the diversion structure 2 includes a rotating shaft 201 rotatably connected to the inner wall of the mounting hole 105. A servo motor 202 is provided on one side of the rotating shaft 201, and a guide strip 203 is provided on the outer wall of the rotating shaft 201. The guide strip 203 is located inside the guide plate 104. The number of rotating shafts 201 is set to multiple. A synchronous pulley 204 is provided at one end of the rotating shaft 201, and a synchronous belt 205 is provided on the outer wall of the synchronous pulley 204. The gas discharged from the guide plate 104 passes through the guide strip 203. When it is necessary to change the direction of the gas, the servo motor 202 is started, and the servo motor 202 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the rotating shafts 201 in other positions to rotate through the synchronous pulley 204 and the synchronous belt 205. Then, the rotating shaft 201 drives the guide strip 203 on the outer wall to swing, thereby changing the direction of the airflow.

[0024] Normal airflow mode: External gas enters the placement chamber (102) through the air inlet (103).

[0025] The gas then enters multiple stacked gas guide pipes (301) and is discharged to the guide plate (104) area through the connecting pipe (302).

[0026] The guide bar (203) of the diversion structure (2) is in the default or preset position to guide the discharged gas, so that the airflow is evenly distributed to the working area inside the drying chamber and ensures that the temperature field is uniform.

[0027] Split mode when single air tube 301 is closed: When it is necessary to close a certain air duct (301), activate the electric push rod (307) corresponding to that air duct 301.

[0028] The electric push rod (307) pushes the first sealing plate (304) to slide on the inner wall of the diversion port (303), and at the same time drives the second sealing plate (305) to rotate through the positioning shaft (306).

[0029] The first sealing plate (304) and the second sealing plate (305) rotate relative to each other and overlap, sealing the outlet of the connecting pipe (302) of the air guide pipe 301, while the diversion port (303) is opened.

[0030] The gas that originally passed through the gas duct 301 flows into the adjacent gas duct (301) through the diversion port (303) and is discharged through other connecting pipes (302), ensuring continuous airflow and avoiding the formation of eddies or pressure accumulation of gas in the closed pipe.

[0031] Airflow direction adjustment mode: When it is necessary to change the airflow direction, start the servo motor (202).

[0032] The servo motor (202) drives the rotating shaft (201) to rotate, and drives all rotating shafts 201 to move synchronously through the synchronous pulley (204) and the synchronous belt (205).

[0033] The guide bar (203) on the rotating shaft (201) swings accordingly, changing the angle of the airflow outlet, thereby adjusting the distribution of airflow in the drying chamber and achieving precise temperature control and uniform airflow.

[0034] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
