Description

Technical Field

[0001] This invention belongs to the field of heating and drying technology, and particularly relates to a stainless steel air-suspended drying oven. Background Technology

[0002] Traditional drying ovens are mostly of a single-piece structure, which has the following drawbacks: difficult maintenance, requiring complete disassembly; uneven hot air distribution leading to large differences in heating of the substrate; cumbersome operation and poor synchronization of the lifting mechanism; high energy consumption and insufficient environmental performance. In existing technologies, some drying ovens use cylinder lifting, but the synchronization accuracy is low, or the single-section structure leads to high maintenance costs, and the cylinder lifting has low stability, easily causing shaking of the internal structure during lifting. Summary of the Invention

[0003] The purpose of this invention is to provide a stainless steel air-suspended drying oven, comprising: a main body, wherein the main body is composed of four drying oven sections connected end to end, each drying oven section having the same structure, and is divided into an upper drying oven and a lower drying oven, wherein the upper drying oven and the lower drying oven are connected by a lifting structure; the top of the upper drying oven is provided with a combustion furnace, an air inlet fan, an exhaust fan and an exhaust valve in sequence from left to right, wherein the air inlet fan is divided into an upper air inlet fan and a lower air inlet fan, and the lifting structure, the combustion furnace, the air inlet fan, the exhaust fan and the exhaust valve are electrically connected to a main control terminal.

[0004] Preferably, the upper oven includes an upper ventilation duct and an upper air chamber, the combustion furnace and the upper air inlet fan are respectively connected to the upper ventilation duct, and the lower end of the upper ventilation duct is connected to the upper air chamber.

[0005] Preferably, the lower oven includes a lower ventilation duct and a lower air chamber, the combustion furnace and the lower air inlet fan are respectively connected to the lower ventilation duct, and the lower end of the lower ventilation duct is connected to the lower air chamber; the upper air chamber is opposite to the lower air chamber.

[0006] Preferably, a row of upper air nozzles is evenly arranged at the bottom of the upper air duct, and a row of lower air nozzles is evenly arranged at the top of the lower air duct, with the upper air nozzles and the lower air nozzles arranged alternately.

[0007] Preferably, the lifting structure includes a motor assembly, which is installed on the top of the third section of the oven. The output end of the motor assembly is connected to the transverse connecting rods on both sides of the upper oven via a vertical connecting shaft and a commutator. The transverse connecting rods are respectively connected to the spiral lifters installed on the outer walls of both sides of each section of the upper oven via the commutator.

[0008] Preferably, the side of the screw jack is also provided with a guide rod parallel to it, the upper oven is mounted on the guide sleeve assembly sleeved on the surface of the screw jack via an upper mounting seat, and the guide rod passes through the upper mounting seat; the outer walls on both sides of the lower oven are provided with lower mounting seats opposite to the upper mounting seats, and the bottom of the screw jack is fixed to the lower mounting seats.

[0009] The beneficial effects of this invention are: The horizontal connecting rod is driven by a motor, vertical connecting shaft, and commutator, which drives the spiral lifters on both sides of each upper oven section to move synchronously. The guide rods ensure that the lifting and lowering are without deviation, thus guaranteeing the stability of the equipment opening and closing.

[0010] By staggering the upper air nozzles at the bottom of the upper air chamber and the lower air nozzles at the top of the lower air chamber, a uniform air film is formed, which suspends the substrate without contact, avoids mechanical damage, and improves the utilization rate of hot air.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figures 1 to 3 As shown, this embodiment provides a stainless steel air-suspended drying oven, including: a box body 1, which is composed of four drying oven sections 2 connected end to end. Each drying oven section 2 has the same structure and is provided with an observation window and a safety inspection door at the bottom. The drying oven 2 is divided into an upper drying oven 201 and a lower drying oven 202, which are connected by a lifting structure 3. The top of the upper drying oven 201 is provided with a combustion furnace 4, an air inlet fan 6, an exhaust fan 7 and an exhaust valve 5 from left to right. The air inlet fan 6 is divided into an upper air inlet fan 601 and a lower air inlet fan 602. The lifting structure 3, the combustion furnace 4, the air inlet fan 6, the exhaust fan 7 and the exhaust valve 8 are electrically connected to the main control terminal.

[0017] The upper oven 201 includes an upper ventilation duct 2011 and an upper air chamber 2012. The combustion furnace 4 and the upper air inlet fan 601 are respectively connected to the upper ventilation duct 2011, and the lower end of the upper ventilation duct 2011 is connected to the upper air chamber 2012.

[0018] The lower oven 202 includes a lower ventilation duct 2021 and a lower air duct 2022. The combustion furnace 4 and the lower air inlet fan 602 are respectively connected to the lower ventilation duct 2021, and the lower end of the lower ventilation duct 2021 is connected to the lower air duct 2022. The upper air duct 2012 is opposite to the lower air duct 2022. A row of upper air nozzles 2013 is evenly arranged at the bottom of the upper air duct 2012, and a row of lower air nozzles 2023 is evenly arranged at the top of the lower air duct 2022. The upper air nozzles 2013 and the lower air nozzles 2023 are arranged alternately.

[0019] The lifting structure 3 includes a motor assembly 301, which is installed on the top of the third section of the oven 2. The output end of the motor assembly 301 is connected to the transverse connecting rods 304 on both sides of the upper oven 201 via a vertical connecting shaft 302 and a commutator 303. The transverse connecting rods 304 are connected to the screw lifters 305 installed on the outer walls of both sides of each section of the upper oven 201 via the commutator 303. The screw lifters 305 are also provided with parallel guide rods 306 on their sides. The upper oven 201 is installed on the guide sleeve assembly 307 sleeved on the surface of the screw lifters 305 via an upper mounting base 308, and the guide rods 306 pass through the upper mounting base 308. The lower oven 202 is provided with lower mounting bases 309 on both sides of its outer walls, opposite to the upper mounting bases 308. The bottom of the screw lifters 305 is fixed to the lower mounting bases 309. When adjustments are needed inside the equipment, ensure that all structures in the equipment are in a static state. At this time, start the motor through the main control terminal. Through the vertical connecting shaft 302, commutator 303 and horizontal connecting rod 304, the screw in the screw lifter 305 rotates, causing the guide sleeve assembly 307 on the surface to drive the upper oven 201 to rise steadily along the direction of the guide rod 306, so that the upper oven 201 and the lower oven 202 slowly separate without causing violent vibration and affecting the stability of the internal structure of the oven 2.

[0020] In summary, this embodiment takes the heating and drying of diaphragm substrate as an example. By setting unwinding and rewinding devices at both ends of the equipment, the substrate to be dried passes between the upper air nozzle 2013 and the lower air nozzle 2023. At this time, the combustion furnace 4 uses electric heating and is connected to the upper ventilation duct 2011 and the lower ventilation duct 2021 respectively. It has been preheated in advance to ensure the uniformity of heat during the drying process. The upper air inlet fan 601 and the lower air inlet fan 602 drive hot air into the upper air chamber 2012 and the lower air chamber 2022 respectively. High-pressure air is evenly sprayed out from the upper air nozzle 2013 and the lower air nozzle 2023, forming an air film suspension layer on the surface of the substrate, generating a lifting force to ensure that the surface of the substrate is evenly heated and that the substrate is suspended in the airflow to avoid mechanical contact. The exhaust fan 7 is a centrifugal fan, which works in conjunction with the exhaust valve 5 to control the discharge of waste gas and moisture, thereby improving drying efficiency, reducing energy consumption, and ensuring temperature uniformity.
