Description

Technical Field

[0001] This invention relates to the field of industrial oven technology, and more particularly to an industrial oven. Background Technology

[0002] Existing industrial ovens can be used by industrial and mining enterprises, scientific research units, military units, university laboratories, medical colleges or biological laboratories. They can be widely used for various workpieces to perform heating and anti-aging treatment, heat treatment, drying treatment, high temperature testing, aging treatment and other purposes. Industrial ovens come in various types, including box-type industrial ovens, trolley-type industrial ovens and tunnel-type industrial ovens, etc.

[0003] Currently, industrial ovens are left to cool down naturally after use before the oven door can be opened. However, this natural cooling process takes a lot of time, which reduces work efficiency.

[0004] Therefore, an industrial oven is designed to effectively improve the cooling efficiency of workpieces inside the oven. Summary of the Invention

[0005] The purpose of this invention is to provide an industrial oven that effectively improves the cooling efficiency of workpieces inside the oven.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] An industrial oven, comprising:

[0008] The oven body is equipped with a baking cavity;

[0009] The exhaust pipe is connected to the baking cavity;

[0010] The air supply device includes an air inlet pipe that connects to the baking cavity, an air intake fan installed in the air inlet pipe, and a one-way valve installed at the end of the air inlet pipe;

[0011] The one-way valve includes a rotating shaft, a guide rod, an elastic element, and two sealing valve covers rotatably connected to the rotating shaft. The rotating shaft is mounted on the end of the air intake pipe. The two opposite ends of the guide rod are fixed to the air intake pipe, and the sealing valve covers are provided with through holes for the guide rod to pass through. The elastic element is compressed and sleeved on the guide rod, and the two opposite ends of the elastic element abut against a sealing valve cover to close the air intake pipe. The diameter of the through hole is the same as the diameter of the guide rod.

[0012] The airflow from the intake fan causes the sealing valve cover to rotate around the rotating axis, so that the intake pipe connects to the baking cavity.

[0013] Optionally, the exhaust pipe and the air supply device are located on opposite sides of the oven body.

[0014] Optionally, the guide rod includes a first connecting part, a semi-circular connecting part, and a second connecting part that are connected end to end in sequence;

[0015] Both the first connecting part and the second connecting part are connected to the inner wall of the air intake pipe, and the semi-circular connecting part surrounds the rotating shaft, and the center line of the semi-circular connecting part coincides with the center line of the rotating shaft.

[0016] Optionally, both the first connecting portion and the second connecting portion are perpendicular to the centerline of the air intake pipe.

[0017] Optionally, both the first connecting portion and the second connecting portion are arc-shaped.

[0018] Optionally, the end of the air intake pipe away from the oven body is funnel-shaped, and the air intake fan is installed inside the end of the air intake pipe away from the oven body;

[0019] A protective net is also provided at one end of the air intake pipe away from the oven body.

[0020] Optionally, one of the sealing valve covers includes a first rotary connection portion rotatably connected to the rotary shaft, and the other sealing valve cover includes a second rotary connection portion rotatably connected to the rotary shaft, with the first rotary connection portion and the second rotary connection portion being alternately arranged.

[0022] Optionally, the through hole is a round hole or a square hole.

[0023] Optionally, the oven body also includes a door.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] In this embodiment, when the interior of the baking chamber does not need to be cooled, the elastic force of the elastic element sleeved on the guide rod pushes the two sealing valve covers to the set position, thereby sealing the end of the air inlet pipe. At this time, the workpiece inside the baking chamber can be baked. When it is necessary to cool the interior of the baking chamber, the air inlet fan is started, and the air from the air inlet fan blows open the two sealing valve covers, so that outside air can enter the baking chamber to expel the heat in the baking chamber more quickly.

[0035] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] This invention provides an industrial oven that can help reduce the cooling time inside the baking cavity without affecting the normal operation of the industrial oven.

[0038] Please see Figures 1 to 5 An industrial oven includes an oven body 1, an exhaust pipe 3, and an air supply device.

[0039] The oven body 1 has a baking cavity, and the exhaust pipe 3 is connected to the baking cavity. The air supply device includes an air inlet pipe 4 connected to the baking cavity, an air intake fan 5 installed in the air inlet pipe 4, and a one-way valve installed at the end of the air inlet pipe 4.

[0040] The one-way valve includes a rotating shaft 9, a guide rod 12, an elastic element 13, and two sealing valve covers 7 rotatably connected to the rotating shaft 9. The rotating shaft 9 is installed at the end of the intake pipe 4. The two opposite ends of the guide rod 12 are fixed to the intake pipe 4, and the sealing valve cover 7 is provided with a through hole 11 for the guide rod 12 to pass through. The elastic element 13 is compressed and sleeved on the guide rod 12, and the two opposite ends of the elastic element 13 abut against a sealing valve cover 7 to close the intake pipe 4. The diameter of the through hole 11 is the same as the diameter of the guide rod 12.

[0041] The airflow blown out by the intake fan 5 can cause the sealing valve cover 7 to rotate around the rotating shaft 9, so that the intake pipe 4 can connect to the baking chamber.

[0042] In actual use, when the heating element inside the oven body 1 heats the workpiece in the baking cavity, the two sealing valve covers 7 cover the air inlet pipe 4 under the elastic force of the elastic element 13, preventing excessive heat from the baking cavity from dissipating to the outside through the air inlet pipe 4. After the oven body 1 finishes baking the workpiece in the baking cavity, the air intake fan 5 starts and continues to work. The air blown out by the air intake fan 5 pushes the sealing valve cover 7 to rotate relative to the rotating shaft 9, so that the air can enter the baking cavity through the gap between the sealing valve cover 7 and the air inlet pipe 4. Then the hot air is accelerated to be discharged from the exhaust pipe 3, which effectively reduces the cooling time of the workpiece and will not cause the workpiece to cool down too quickly, thus preventing quality problems.

[0043] In addition, it should be noted that the air enters the baking chamber through the gap between the sealing valve cover 7 and the air inlet pipe 4. At this time, the opening of the sealing valve cover 7 is relatively small, and the air flows along the cavity wall of the baking chamber instead of being blown directly onto the workpiece. This effectively avoids the problem of excessive local cooling of the workpiece, improves the production efficiency of the workpiece, and effectively ensures the production quality of the workpiece.

[0044] Optionally, the exhaust pipe 3 and the air supply device are located on opposite sides of the oven body 1, which makes the flow length of the outside air longer and improves the cooling efficiency.

[0045] Optionally, such as Figure 4 and Figure 5 As shown, the guide rod 12 includes a first connecting part 121, a semi-circular connecting part 122, and a second connecting part 123 connected in sequence. The first connecting part 121 and the second connecting part are both connected to the inner wall of the air intake pipe 4, and the semi-circular connecting part 122 surrounds the rotating shaft 9, and the center line of the semi-circular connecting part 122 coincides with the center line of the rotating shaft 9.

[0046] It should be noted that the semi-circular connecting part 122 surrounds the rotating shaft 9, and the center line of the semi-circular connecting part 122 coincides with the center line of the rotating shaft 9. This makes the rotation of the sealing valve cover 7 on the semi-circular connecting part 122 smoother and not restricted by the guide rod 12. In addition, the diameter of the through hole 11 is the same as the diameter of the guide rod 12, which improves the sealing effect.

[0047] Optionally, both the first connecting portion 121 and the second connecting portion 123 are perpendicular to the centerline of the intake pipe 4. In this case, when the two sealing valve covers 7 close the intake pipe 4, the sealing valve cover 7 abuts against the first connecting portion 121 or the second connecting portion 123 to achieve a limiting position. That is, the sealing valve cover 7 can be installed not only on... Figure 3 On the end face of the intake pipe 4 shown, it can also be installed inside the rear end of the intake pipe 4. When the sealing valve cover 7 is installed inside the intake pipe 4, the sealing valve cover 7 is semi-circular and its radius is equal to the inner diameter of the intake pipe 4.

[0048] Optionally, such as Figure 4 As shown in the diagram, both the first connecting part 121 and the second connecting part 123 are arc-shaped. At this time, the sealing valve cover 7 abuts against the end face of the intake pipe 4 to complete the sealing requirement.

[0049] Optionally, the end of the air intake pipe 4 furthest from the oven body 1 is funnel-shaped, and the air intake fan 5 is installed inside this end of the air intake pipe 4. A protective mesh 6 is also provided at the end of the air intake pipe 4 furthest from the oven body 1. The funnel shape of the end of the air intake pipe 4 furthest from the oven body 1 increases the installation space for the air intake fan 5 and effectively increases the air intake volume, thereby improving the cooling efficiency inside the baking cavity. The protective mesh 6 effectively prevents external objects from entering the air intake pipe 4, improving the safety of the industrial oven.

[0050] Optionally, one sealing valve cover 7 includes a first rotary connecting portion 71 rotatably connected to the rotating shaft 9, and the other sealing valve cover 7 includes a second rotary connecting portion 72 rotatably connected to the rotating shaft 9, with the first rotary connecting portion 71 and the second rotary connecting portion 72 being alternately arranged.

[0051] like Figure 4 and Figure 5 As shown, the first rotary connecting part 71 and the second rotary connecting part 72 can help to better seal the air intake pipe 4.

[0052] Optionally, the elastic element 13 is a spring, and the spring compression sleeve is disposed on the guide rod 12.

[0053] Optionally, the through hole 11 can be a round hole or a square hole, as long as the cross-sectional shape of the through hole 11 matches the cross-sectional shape of the guide rod 12.

[0054] Optionally, the oven body 1 also includes a door 2. After the workpiece has cooled to the set temperature, the door 2 is opened to remove the workpiece from the baking cavity.
