Description

Technical Field

[0001] This utility model relates to the field of box furnace cooling technology, and in particular to a rapid cooling device for box furnaces. Background Technology

[0002] Box furnaces are common industrial heating equipment. Their main body is a closed box-shaped structure, using internal heating elements (such as resistance wires and gas burners) to achieve high-temperature heat treatment of materials. They are widely used in metal quenching, annealing, sintering, and high-temperature processing of materials such as ceramics and glass. Box furnaces are characterized by uniform heating, high temperature control precision, and ease of operation. However, after operation, the furnace temperature often reaches hundreds or even thousands of degrees Celsius. Relying solely on natural cooling is not only time-consuming but also affects the efficiency of subsequent workpiece handling and processing. Prolonged high temperatures may even cause aging of furnace components, shortening the equipment's lifespan. In industrial production, the cooling efficiency of box furnaces directly affects production rhythm and processing quality. For workpieces requiring strict control of cooling rate (such as the quenching of certain metal materials), natural cooling may lead to uneven internal structure, affecting mechanical properties. In continuous production scenarios, slow furnace cooling extends production intervals and reduces equipment utilization. Therefore, this application proposes a rapid cooling device for box furnaces to improve their cooling efficiency. Utility Model Content

[0003] The main objective of this invention is to provide a rapid cooling device for box furnaces, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rapid cooling device for a box-type furnace includes a box-type furnace body. A mounting frame is fixedly installed at one end of the furnace body. An adjustable cooling assembly is rotatably mounted on the mounting frame. The adjustable cooling assembly consists of an L-shaped plate, a mounting pipe, a connecting plate, a ventilation mesh plate, and cooling fans. The mounting pipe is fixedly installed at one end of the L-shaped plate, the connecting plate is fixedly installed at the other end of the L-shaped plate, and the ventilation mesh plate is fixedly installed at one end of the connecting plate. There are two cooling fans, each fixedly installed at one end of the ventilation mesh plate. A fixing assembly is fixedly installed on the mounting frame. The fixing assembly consists of a mounting rod, a spring, an anti-detachment plate, a movable plate, and U-shaped clamps. The spring is sleeved on the mounting rod, the anti-detachment plate is fixedly installed at the upper end of the mounting rod, the movable plate is movably sleeved on the mounting rod, and three U-shaped clamps are fixedly installed on the three end faces of the movable plate.

[0005] Preferably, the box furnace body is equipped with a sealed door.

[0006] Preferably, the mounting frame consists of a U-shaped frame and a fixed shaft, the fixed shaft being fixedly installed on the inner wall of the U-shaped frame, and the U-shaped frame being fixedly installed at one end of the box furnace body.

[0007] Preferably, the mounting tube on the adjustable cooling assembly is rotatably sleeved on the fixed shaft on the mounting bracket.

[0008] Preferably, the mounting rod on the fixing component is fixedly mounted on the upper end of the U-shaped frame on the mounting bracket, the movable plate has a square hole, the movable plate is movably sleeved on the mounting rod through the square hole, the spring is located at the upper end of the movable plate, and one of the U-shaped clips is sleeved on the L-shaped plate on the adjustable cooling component.

[0009] Compared with the prior art, the present invention has the following beneficial effects: By installing a mounting frame at one end of the box furnace body, and mounting an adjustable cooling assembly consisting of an L-shaped plate, mounting pipe, connecting plate, ventilation mesh plate, and cooling fan on the mounting frame, the adjustable cooling assembly is rotated around a fixed axis, aligning the cooling fan with the opening of the box furnace body. This accelerates the airflow speed inside the box furnace body, rapidly removing heat and significantly improving the cooling efficiency. This solves the problem of excessively long natural cooling time inside the box furnace body, which is beneficial for improving production pace and equipment utilization. A fixing assembly consisting of a mounting rod, spring, anti-detachment plate, moving plate, and U-shaped clamp is installed on the mounting frame. Under the spring force, the U-shaped clamp on the moving plate can clamp the L-shaped plate of the adjustable cooling assembly, thus fixing the adjusted cooling assembly in place and preventing angle deviation due to vibration during operation, which would affect the cooling effect. When the angle needs to be adjusted again, simply pull the moving plate upwards to compress the spring, separating the U-shaped clamp from the L-shaped plate, allowing easy rotation of the adjustable cooling assembly. This makes operation convenient and flexible. Attached Figure Description

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Please see Figure 1 , Figure 2 , Figure 3 As shown, a rapid cooling device for a box furnace includes a box furnace body 1. A mounting frame 2 is fixedly installed at one end of the box furnace body 1. An adjustable cooling assembly 3 is rotatably mounted on the mounting frame 2. The adjustable cooling assembly 3 consists of an L-shaped plate 8, a mounting pipe 9, a connecting plate 10, a ventilation mesh plate 11, and cooling fans 12. The mounting pipe 9 is fixedly installed at one end of the L-shaped plate 8, the connecting plate 10 is fixedly installed at the other end of the L-shaped plate 8, the ventilation mesh plate 11 is fixedly installed at one end of the connecting plate 10, and there are two cooling fans 12, both fixedly installed on the ventilation mesh plate. At one end of the 11, a fixing component 4 is fixedly installed on the mounting frame 2. The fixing component 4 consists of a mounting square rod 13, a spring 14, an anti-detachment plate 15, a movable plate 16, and U-shaped clamps 18. The spring 14 is sleeved on the mounting square rod 13, the anti-detachment plate 15 is fixedly installed on the upper end of the mounting square rod 13, the movable plate 16 is movably sleeved on the mounting square rod 13, and there are three U-shaped clamps 18, which are respectively fixedly installed on the three end faces of the movable plate 16. By setting the mounting frame 2 at one end of the box furnace body 1, and setting the mounting frame 2 with an L-shaped plate 8, a mounting tube 9, and a connecting... The adjustable cooling assembly 3, consisting of plate 10, ventilation mesh plate 11, and cooling fan 12, rotates around fixed axis 7, aligning cooling fan 12 with the opening of the box furnace body 1. This accelerates airflow within the box furnace body 1, rapidly removing heat and significantly improving cooling efficiency. This solves the problem of excessively long natural cooling time, improving production pace and equipment utilization. Furthermore, by installing mounting rods 13, springs 14, and anti-detachment mechanisms on the mounting frame 2... The fixing assembly 4, consisting of plate 15, movable plate 16, and U-shaped clamp 18, can clamp the L-shaped plate 8 of the adjustable cooling assembly 3 under the elastic force of spring 14. This fixes the adjustable cooling assembly 3 after the angle has been adjusted, preventing it from shifting due to vibration or other reasons during operation and affecting the cooling effect. At the same time, when the angle needs to be adjusted again, simply pull the movable plate 16 upward to compress the spring 14, causing the U-shaped clamp 18 to separate from the L-shaped plate 8, and the adjustable cooling assembly 3 can be easily rotated. The operation is convenient and flexible.

[0014] Specifically, a sealing door 5 is installed on the main body 1 of the box furnace. The mounting frame 2 consists of a U-shaped frame 6 and a fixed shaft 7. The fixed shaft 7 is fixedly installed on the inner wall of the U-shaped frame 6, and the U-shaped frame 6 is fixedly installed at one end of the main body 1 of the box furnace. The mounting tube 9 on the adjustable cooling assembly 3 is rotatably sleeved on the fixed shaft 7 on the mounting frame 2. The mounting square rod 13 on the fixed assembly 4 is fixedly installed on the upper end of the U-shaped frame 6 on the mounting frame 2. A square hole 17 is opened on the moving plate 16. The moving plate 16 is movably sleeved on the mounting square rod 13 through the square hole 17. The spring 14 is located at the upper end of the moving plate 16. One of the U-shaped clamps 18 The L-shaped plate 8, fitted onto the adjustable cooling assembly 3, is used by first opening the sealing door 5 and placing the workpiece to be processed into the box furnace body 1. Then, the sealing door 5 is closed, and the box furnace body 1 is started to heat the workpiece. After processing, the box furnace body 1 is closed to stop heating the workpiece. Next, the sealing door 5 is opened, and then the moving plate 16 is pulled upwards to separate one of the U-shaped clamps 18 from the L-shaped plate 8. At this time, the spring 14 is compressed by the moving plate 16, thus releasing the fixation of the adjustable cooling assembly 3. Then, the adjustable cooling assembly 3 is rotated so that the mounting tube 9 wraps around the mounting bracket 2. The fixed shaft 7 rotates horizontally, aligning the cooling fan 12 with the opening of the box furnace body 1. Then, the moving plate 16 is released, allowing the U-shaped clamp 18 to move downwards under the elastic force of the spring 14. This causes one of the U-shaped clamps 18 to re-clamp the L-shaped plate 8, thus fixing the adjustable cooling assembly 3. The cooling fan 12 is then activated, blowing air into the box furnace body 1 to accelerate airflow. The cooling fan 12 continuously removes heat from the box furnace body 1 until the temperature inside the box furnace body 1 drops to a suitable range. Turn off the cooling fan 12, then pull the moving plate 16 and U-shaped clamp 18 upwards, so that one of the U-shaped clamps 18 separates from the L-shaped plate 8, thereby releasing the fixation of the adjustable cooling component 3. Then rotate the adjustable cooling component 3 in the opposite direction on the fixed shaft 7, so that the adjustable cooling component 3 moves to a position that does not affect the loading and unloading of workpieces in the box furnace body 1. Finally, release the moving plate 16, so that one of the U-shaped clamps 18 is sleeved on the L-shaped plate 8 under the elastic force of the spring 14. Then fix the adjustable cooling component 3 with the fixing component 4, and then the workpiece can be taken out from the box furnace body 1.

[0015] When the adjustable cooling component 3 is rotated to the front of the box furnace body 1, its overall position is adjusted to the lower part of the opening of the box furnace body 1. At this time, the cooling fan 12 is directly facing the area below the opening of the box furnace body 1. When the cooling fan 12 starts blowing air into the box furnace body 1, the blown cold air will form an upward airflow inside the box furnace body 1, pushing the hot air inside the box furnace body 1 to naturally drift out from the upper part of the opening. Through this circulation of airflow, the heat inside the box furnace body 1 can be removed more efficiently, increasing the cooling rate. The opening size of the U-shaped clamp 18 must match the thickness of the L-shaped plate 8 to ensure that the U-shaped clamp 18 fits tightly on the L-shaped plate 8. Under the elastic force of the spring 14 of the fixing component 4, the U-shaped clamp 18 can form a stable clamping force on the L-shaped plate 8. Thus, during the operation of the adjustable cooling component 3, even if it is affected by the vibration generated by the operation of the cooling fan 12 or the slight external impact, it will not shake. This ensures that the cooling fan 12 is always accurately aligned with the opening of the box furnace body 1, maintaining a stable cooling effect.

[0016] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
