Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to an air duct structure for an energy-saving oven. Background Technology

[0002] An oven is a general-purpose equipment used for drying materials. It achieves the purpose of drying by evaporating the moisture in the material through heating. It is suitable for industries such as chemical, food, and pharmaceutical. It removes moisture from materials by heating to maintain product quality. In order to ensure the flow of hot air during the drying process, an air duct structure is usually used to regulate the flow of hot air, so that it flows according to a preset trajectory and achieves the heating and drying operation of the material.

[0003] However, the existing oven duct structure cannot preheat the gas when adding new gas for ventilation. Directly heating the inside of the oven will cause the internal temperature to drop, which is not conducive to maintaining the original high temperature for drying operations. At the same time, the exhaust gas cannot be reused, resulting in a waste of heat energy. Utility Model Content

[0004] The purpose of this invention is to provide an air duct structure for an energy-saving drying oven, which has the advantage of preheating the incoming gas during the intake process. It utilizes the heat present in the internal gas during the exhaust process to preheat the newly added gas, thereby ensuring that the gas is already heated upon addition and does not differ too much from the original internal temperature of the drying oven, thus guaranteeing a continuous drying effect and solving the problems mentioned in the background art.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] This utility model provides an air duct structure for an energy-saving drying oven, including a cabinet 1;

[0033] The interior of the housing 1 is equipped with a hot air circulation mechanism 2 for internal hot air flow, and the back of the housing 1 is equipped with an air intake and exhaust mechanism 3 for air intake and exhaust.

[0034] Hot air circulation mechanism 2 includes;

[0035] An output component is located at the top of the housing 1. Inside the housing 1, there is an air outlet component and an air intake component connected to the air outlet component.

[0036] The intake and exhaust mechanism 3 includes;

[0037] An external exhaust component is located on the back of housing 1, and a gas delivery component is connected to the external exhaust component. An air intake component is also located on the back of housing 1.

[0038] Preferred;

[0039] like Figure 3 As shown, the output components include;

[0040] The motor 25 is fixedly installed on the top of the housing 1. The output shaft of the motor 25 is keyed to the shaft 26 and the fan 27 fixed to the bottom of the shaft 26. It serves as the power output for internal air circulation. The shaft 26 is used for rotational transmission. The fan 27 is adapted to the air duct 21 to draw in air and exhaust it, achieving the effect of internal air circulation.

[0041] further;

[0042] like Figure 3 As shown, the air outlet assembly includes;

[0043] The air duct 21 is fixedly installed inside the housing 1. The inner wall of the air duct 21 has holes 22. The air duct 21 can direct the flow of the specified gas and blow it evenly onto the material through the holes 22 to complete the drying operation.

[0044] in;

[0045] like Figure 3 As shown, the intake assembly includes;

[0046] The air inlet 23 is located on the top of the inner side of the air duct 21. A mesh plate 24 is fixedly installed inside the air inlet 23. The air inlet 23 is designed to fit the air intake position at the bottom of the fan 27, while the mesh plate 24 serves to block and protect the air.

[0047] During internal circulation, the motor 25 is first started and the fan 27 is rotated via the shaft 26. The shaft 26 is connected to the air duct 21 and the top of the box 1 in a through-type rotating connection to ensure its stability during rotation. Then, the fan 27 draws in air from the bottom and discharges air from both sides. The discharged hot air flows inside the air duct 21 and is then blown toward the material through the holes 22, thus achieving the effect of internal circulation. The equidistant spacing of the holes 22 ensures the uniformity of drying during internal circulation.

[0048] It is worth explaining;

[0049] like Figure 4 As shown, the external discharge components include;

[0050] The outer cover 31 is fixedly installed on the back of the housing 1. An exhaust fan 32 is installed inside the outer cover 31. The outer cover 31 can be used to block the heat when the gas is discharged, thereby reducing leakage. It can also support the components connected to its inner and outer walls. The exhaust fan 32 is mainly used to draw in the gas inside and then discharge it to the designated container and pipe outside.

[0051] Going a step further;

[0052] like Figure 4 As shown, the gas delivery assembly includes;

[0053] The first conveying pipe 33 is connected to the exhaust end of the exhaust fan 32. The exhaust end of the first conveying pipe 33 is connected to the coil 34 and the second conveying pipe 35 connected to the exhaust end of the coil 34. This enables the conveying and transmission of the discharged hot air. Furthermore, based on the shape design of the coil 34, it enables the pre-treatment and heating of the gas inside the intake channel during air intake.

[0054] at last;

[0055] like Figure 4 As shown, the intake assembly includes;

[0056] The exhaust pipe 36 is connected to the back of the housing 1. An intake fan 37 and a filter 38 connected to the intake end of the intake fan 37 are fixedly installed on the back of the outer cover 31. The exhaust end of the intake fan 37 is connected to the exhaust pipe 36, which can realize the intake operation during the air exchange process, thereby drawing the external gas into the interior of the housing 1. The filter 38 can realize the filtration operation during the intake to ensure the cleanliness of the incoming gas.

[0057] During intake and exhaust operations, the exhaust fan 32 is first started to extract the internal hot air, which is then transported to the inside of the coil 34 through the first delivery pipe 33. Based on the shape design of the coil 34 and its contact-type winding around the outside of the exhaust pipe 36, the exhaust pipe 36 can be preheated. After being heated to the preset required temperature, the intake fan 37 is started to extract external gas into the housing 1. When extracting gas, the gas is pre-filtered through the filter 38 and then enters the inside of the housing 1 through the exhaust pipe 36. When the gas is output from the inside of the exhaust pipe 36, its inflow needs to be controlled and kept small to ensure that the incoming gas is preheated. The gas entering the housing then has a certain temperature and will not cause a sudden drop in the temperature inside the housing 1. This not only realizes the ventilation operation during intake and exhaust, but also allows the incoming gas to be preheated by the hot gas during exhaust, thereby achieving the purpose and effect of energy saving.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
