Description

Technical Field

[0001] This invention relates to the field of drying oven technology, and more specifically to a tunnel-type drying oven module system with a rapid heating nozzle mechanism. Background Technology

[0002] As a commonly used drying equipment in industrial production, the core working principle of an oven is to circulate hot air within the chamber using a fan, thereby efficiently utilizing thermal energy and reducing energy consumption. Specifically, the air source is a circulating fan motor driving an impeller, which heats the air to form hot air. This hot air is then transported through air ducts to the inner chamber of the oven to exchange heat with the materials. The used air is then drawn back into the air ducts to participate in the recirculation and heating process. This hot air circulation method gives the oven high thermal efficiency and high energy utilization, making it widely used for drying various industrial materials and one of the most versatile and ideal drying equipment currently available.

[0003] However, existing traditional drying ovens still have significant drawbacks in practical applications:

[0004] 1. Traditional ovens mainly rely on overall circulating hot air for heating, which cannot provide the large flow rate and high velocity of local hot air that may be needed in the production process. This makes it difficult to achieve rapid heating of specific areas of materials, limiting their application in scenarios where heating efficiency and local temperature rise rate are highly required.

[0005] 2. Existing equipment is mostly integrated in design, which has weak compatibility with existing production lines. It is difficult to expand capacity flexibly according to production needs, and it is also impossible to upgrade or replace the ovens separately, which increases the cost and difficulty for enterprises to modify or upgrade their production lines. Summary of the Invention

[0006] The purpose of this invention is to provide a tunnel-type oven module system with a rapid heating nozzle mechanism, which can improve heating efficiency, reduce energy consumption, lower equipment costs, and facilitate oven expansion and individual upgrades for existing production lines.

[0007] To achieve the above objectives, this application proposes a tunnel-type oven module system with a rapid heating nozzle mechanism, comprising:

[0008] Equipment brackets serve as support for the entire equipment;

[0009] The outer cover is fixed to the equipment bracket;

[0010] Insulation boards are fixed to the equipment bracket and the outer cover;

[0011] The oven is divided into an upper oven and a lower oven. The lower oven is fixed on the equipment support, and the upper oven is fixed on the insulation board.

[0012] In one embodiment, the outer cover includes:

[0013] The exterior panel is fixed to the equipment bracket;

[0014] Pneumatic gates for material entry and exit are placed on the outer cover to control the entry and exit of materials;

[0015] The observation door, placed on the exterior cover, enables non-contact monitoring.

[0016] In one embodiment, the insulation board includes several insulation modules.

[0017] In one embodiment, the oven includes: an outer shell, an inner shell, a circulating air heating device, a rapid heating nozzle mechanism, an internal air duct, and an oven cover; the outer shell is connected to the inner shell, with insulation cotton filling the space between them for heat insulation; the circulating air heating device is fixed to the inner shell and serves as the oven's heat source; the rapid heating nozzle mechanism and the internal air duct are fixed to the inner shell, and air is drawn out from the nozzle of the rapid heating nozzle mechanism; the oven cover is fixed to the outer shell and serves as a channel for separating exhaust and intake air, and a perforated plate is provided on the oven cover to achieve uniform airflow.

[0018] In one embodiment, the circulating air heating device includes: a motor, a motor mounting bracket, a high-temperature resistant impeller, a drive shaft with an air-cooled impeller, and an electric heater. The motor is fixed on the motor mounting bracket, which is fixed on the outer shell of the oven. The motor drives the high-temperature resistant impeller. The high-temperature resistant impeller is fixed to the end of the drive shaft with the air-cooled impeller, converting mechanical energy into fluid kinetic energy to drive the directional flow of high-temperature gas. The electric heater is fixed to the inner shell of the oven and, through the resistance effect, efficiently converts the input electrical energy into heat energy to directionally heat the flowing gas, bringing the gas to a preset temperature. Hot air enters the heating area through the oven's air distribution perforation plate and then returns to the electric heater through the return air channels on both sides of the oven, thus forming a circulating hot air with a constant temperature.

[0019] In one embodiment, the rapid heating nozzle mechanism includes: a nozzle telescopic cylinder, a drive shaft, an inner nozzle sleeve, a fixed housing, a nozzle, an outer nozzle sleeve, and a connecting plate. The nozzle telescopic cylinder is fixed to the oven housing. The drive shaft and the inner nozzle sleeve are connected via the connecting plate. The nozzle is fixed to the inner nozzle sleeve via an internal thread. The outer nozzle sleeve is fixed to the fixed housing. The inner nozzle sleeve is inserted into the outer nozzle sleeve. Telescopic movement of the inner nozzle sleeve controls whether it blocks the ventilation holes on the side wall of the outer nozzle sleeve, thus controlling the ventilation of the nozzle. When the nozzle telescopic cylinder extends, the inner nozzle sleeve extends, the ventilation holes on the outer nozzle sleeve are connected, and hot air is ejected from the nozzle, achieving localized rapid heating. When the nozzle telescopic cylinder retracts, the inner nozzle sleeve retracts, the ventilation holes on the outer nozzle sleeve are misaligned, and the nozzle stops ventilating. An external infrared thermometer is connected to monitor the oven temperature.

[0020] The advantages of the above technical solutions adopted in this invention compared with the prior art are as follows:

[0021] This invention addresses the shortcomings of traditional ovens in meeting the demands of rapid heating with high-flow-rate hot air by utilizing a circulating air heating device. It provides a constant-temperature circulating hot air supply to the oven, fulfilling the basic functional requirements of the production line. Furthermore, a rapid-heating nozzle mechanism delivers the necessary localized high-speed hot air for specific production processes. The rapid-heating nozzles output fast-flow-rate hot air and rapid temperature rise, improving heating efficiency and reducing energy consumption. The multi-functional design reduces equipment costs for businesses, while the modular design facilitates expansion or individual upgrades of existing production lines. Attached Figure Description

[0033] Example 1

[0034] Please see Figure 1-5 This embodiment provides a tunnel-type oven module system with a rapid heating nozzle mechanism, including:

[0035] Equipment bracket 1, outer cover 2, insulation board 3, oven 4. The outer cover 2 and insulation board 3 are fixed on the equipment bracket 1. The outer cover 2 is detachable for easy equipment maintenance.

[0036] In this embodiment, the outer cover 2 includes an outer panel 21, an observation door 22, and a pneumatic gate 23 for material inlet and outlet. The observation door 22 is placed on the outer cover, allowing for convenient observation of the working conditions inside the oven; the pneumatic gate 23 controls the inlet and outlet of materials.

[0037] The oven 4 includes a circulating air heating device 41, a rapid heating nozzle mechanism 42, an internal air duct 43, an oven cover 44, an oven outer shell 45, and an oven inner shell 46. The tunnel-type oven module system with a rapid heating nozzle mechanism has two ovens with identical structures. The upper oven has an observation port, the lower oven is fixed on the equipment support 1, and the upper oven is fixed on the insulation board 3. The oven 4 and the insulation board 3 form the working area of ​​the tunnel-type oven module system.

[0038] The circulating air heating device 41 includes an electric heater 411, a high-temperature resistant impeller 412, an air-cooled impeller 413, a drive shaft 414, a coupling 415, a motor 416, and a motor mounting bracket 417. The motor 416 is externally mounted outside the oven 4. The air-cooled impeller 413 is fixed on the drive shaft 414 and rotates synchronously, providing air cooling to the drive shaft 414 and related support bearings. The drive shaft 414 and the motor 416 bracket are separated by a coupling 415 to prevent thermal bridging. When the motor 416 starts, it drives the high-temperature resistant impeller 412 through the drive shaft 414. The high-temperature resistant impeller 412 drives the air in front of the electric heater 411. After being heated by the electric heater 411, the air is heated to the set temperature. The hot air enters the heating area through the air distribution plate of the oven 4 and then returns to the electric heater 411 through the return air channels on both sides of the oven 4, thus forming a circulating hot air with a constant temperature.

[0039] The rapid heating nozzle mechanism 42 includes a nozzle telescopic cylinder 421, a drive shaft 422, an inner nozzle sleeve 423, a nozzle 424, a fixed housing 425, an outer nozzle sleeve 426, and a connecting plate 427. The nozzle telescopic cylinder 421 is fixed to the outer shell of the oven. The drive shaft 422 and the inner nozzle sleeve 423 are connected by the connecting plate 427. The nozzle 424 is fixed to the inner nozzle sleeve 423 by an internal thread. The outer nozzle sleeve 426 is fixed to the fixed housing. The inner nozzle sleeve 423 is inserted into the outer nozzle sleeve 426. The telescopic movement of the inner nozzle sleeve controls whether the inner nozzle sleeve 423 blocks the ventilation hole on the side wall of the outer nozzle sleeve 426, thus controlling the ventilation of the nozzle. When the nozzle telescopic cylinder 421 extends, the inner sleeve 423 of the nozzle extends, and the ventilation holes on the outer sleeve 426 of the nozzle connect, allowing hot air to be ejected from the nozzle 424, achieving localized rapid heating. When the nozzle telescopic cylinder 421 retracts, the inner sleeve 423 retracts, and the ventilation holes on the outer sleeve 426 of the nozzle are misaligned, preventing ventilation. This rapid heating nozzle mechanism can provide the localized high-speed hot air required for production processes. Because the rapid heating nozzle outputs hot air with a high flow rate and rapid temperature rise, it improves heating efficiency, thereby reducing energy consumption. Its multi-functional design also reduces equipment costs for enterprises.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
