Description

Technical Field

[0001] This utility model relates to the field of aging furnace technology, specifically an energy-saving high-temperature aging furnace. Background Technology

[0002] An aging furnace, also known as an aging chamber, is a device specifically designed to accelerate the aging process of materials. By simulating temperature changes in natural or extreme environments, it assesses the durability and lifespan of materials. Particularly in the electronics and electrical appliance industry, aging furnaces accelerate the aging of electronic and electrical appliances through high-temperature environments, helping manufacturers test the performance stability of electronic and electrical materials under high-temperature conditions, thereby optimizing designs and improving product quality.

[0003] The published patent document CN212514802U discloses an energy-saving high-temperature aging chamber. This patent document describes a method where a drive motor rotates a rotating rod in both directions, which in turn drives a gear to rotate in both directions. The gear drives a toothed plate to move back and forth, which in turn drives a support box to move back and forth. The support box, in turn, drives the batteries placed in the placement box to move back and forth. The moving batteries are in full contact with the hot air from the nozzle, resulting in uniform heating of the battery surface. This method has high efficiency and shortens the aging time. However, the aforementioned patent does not reduce the heat transfer from the chamber to the outside, causing heat loss and wasting energy. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving high-temperature aging furnace, which solves the problems mentioned in the background art.

[0005] This application provides an energy-saving high-temperature aging furnace, including an outer casing and an inner casing. The inner casing is fixedly connected to the inside of the outer casing, and polyurethane foam filler is used to fill the space between the outer wall of the inner casing and the inner wall of the outer casing. A matching door is hinged to one side of the front of the outer casing. A fiberglass wool board matching the inner casing is provided on one side of the door, and an I-shaped component is provided on the other side of the door. Sliding shafts are fixedly connected to the four corners of the fiberglass wool board near the door. One end of the sliding shaft passes through the door and is fixedly installed with the I-shaped component, and the sliding shaft is slidably connected to the door. A positioning shaft passes through and is slidably connected to the I-shaped component. One end of the positioning shaft is fixedly installed with the door, and a disc is fixedly installed on the other end of the positioning shaft. A spring is sleeved on the positioning shaft, and the two ends of the spring are respectively connected to the I-shaped component and the disc.

[0006] Optionally, a partition is fixedly connected inside the inner chamber, which divides the interior of the inner chamber into a circulation chamber and an aging test chamber, and an air intake pipe and an exhaust pipe are connected through the partition with an interference fit.

[0007] Optionally, the aging test chamber is provided with several placement trays at equal intervals. Each placement tray is provided with a matching mesh tube above it. One end of the mesh tube is connected to the air inlet pipe, and the bottom of the mesh tube is connected to several nozzles.

[0008] Optionally, an electric heating box and an air pump are fixedly installed inside the circulation chamber. The air inlet of the electric heating box is connected to the upper end of the exhaust pipe, and the exhaust end of the electric heating box is connected to the input end of the air pump.

[0010] Optionally, the four corners of the bottom of the outer casing are fixedly connected with support feet, and the bottom of the support feet is provided with anti-slip pads.

[0011] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0012] 1. The technical solution of this application reduces the heat transfer from the inner box to the outside by filling the space between the outer box and the inner box with polyurethane foam filler. Furthermore, during the closing process, the glass fiber cotton board is pressed tightly against the front side of the inner box by the I-shaped parts, sliding shaft, positioning shaft, disc and spring, which further reduces the heat transfer from the inner box to the outside, thereby reducing the loss of heat inside the inner box and achieving a good energy-saving effect.

[0013] 2. The technical solution of this application, through the coordinated use of partitions, circulation chambers, aging test chambers, placement trays, air inlet pipes, exhaust pipes, mesh pipes, nozzles, electric heating boxes and air pumps, avoids the situation where some test devices block the hot air of other test devices, resulting in good aging test effect, and also realizes the hot air circulation function, thereby increasing the efficiency of aging test.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-2 This utility model provides an energy-saving high-temperature aging furnace, including an outer box 1 and an inner box 2. The inner box 2 is fixedly connected to the inside of the outer box 1, and polyurethane foam filler 3 is filled between the outer wall of the inner box 2 and the inner wall of the outer box 1. A matching door 4 is hinged to one side of the front of the outer box 1. A glass fiber cotton board 5 matching the inner box 2 is provided on one side of the door 4, and an I-shaped component 16 is provided on the other side of the door 4. Sliding shafts 17 are fixedly connected to the four corners of the glass fiber cotton board 5 near the door 4. One end of the sliding shaft 17 passes through the door 4 and is fixedly installed with the I-shaped component 16, and the sliding shaft 17 is slidably connected to the door 4. A positioning shaft 18 passes through and is slidably connected to the I-shaped component 16. One end of the positioning shaft 18 is fixedly installed with the door 4, and a disc 19 is fixedly installed on the other end of the positioning shaft 18. A spring 20 is sleeved on the positioning shaft 18, and the two ends of the spring 20 are respectively connected to the I-shaped component 16 and the disc 19.

[0022] In this technical solution, by filling the space between the outer casing 1 and the inner casing 2 with polyurethane foam filler 3, the heat transfer from the inner casing 2 to the outside is reduced, and the heat loss inside the inner casing 2 is also reduced. During the closing of the door 4, the glass fiber cotton board 5 will contact the opening on the front side of the inner casing 2. The elastic force of the spring 20 causes the I-shaped part 16 and the sliding shaft 17 to move the glass fiber cotton board 5, so that the glass fiber cotton board 5 is tightly attached to the front side of the inner casing 2, reducing the heat transfer from the inner casing 2 to the outside and further reducing the heat loss inside the inner casing 2, resulting in a better energy-saving effect.

[0023] In some technical solutions, such as Figure 1 As shown, a partition 6 is fixedly connected inside the inner chamber 2. The partition 6 divides the interior of the inner chamber 2 into a circulation chamber 7 and an aging test chamber 8. An air intake pipe 9 and an exhaust pipe 10 are connected through the partition 6 with an interference fit.

[0024] When in use, separating the circulation chamber 7 and the aging test chamber 8 facilitates management.

[0025] In some technical solutions, such as Figure 1 and Figure 3 As shown, several placement trays 11 are equidistantly arranged inside the aging test chamber 8. Each placement tray 11 is equipped with a matching mesh tube 12 above it. One end of the mesh tube 12 is connected to the air inlet pipe 9, and several nozzles 21 are connected to the bottom of the mesh tube 12.

[0026] During use, the mesh tube 12 and several nozzles 21 allow hot air to be blown out from above the detection devices in the placement tray 11, preventing some detection devices from blocking the hot air from other detection devices, resulting in good aging detection effect.

[0027] In some technical solutions, such as Figure 1 As shown, an electric heating box 13 and an air pump 14 are fixedly installed inside the circulation chamber 7. The air inlet of the electric heating box 13 is connected to the upper end of the exhaust pipe 10, and the exhaust end of the electric heating box 13 is connected to the input end of the air pump 14. The output end of the air pump 14 is connected to the upper end of the air inlet pipe 9.

[0028] In use, the air pump 14 can deliver the air in the aging test chamber 8 to the electric heating box 13 through the exhaust pipe 10. The electric heating box 13 heats the air and then returns it to the aging test chamber 8 through the air inlet pipe 9, realizing the hot air circulation function, thereby increasing the aging test efficiency.

[0029] In some technical solutions, such as Figure 1 and Figure 4 As shown, several sliding rods 22 are fixedly connected to the front and rear parts of the inner walls on both sides of the aging test chamber 8. Mounting parts 23 are symmetrically fixedly connected to both sides of the placement tray 11. The mounting part 23 has a groove 24 that matches the sliding rod 22 on the side away from the placement tray 11. One end of the sliding rod 22 is inside the groove 24.

[0030] In use, the placement plate 11 can be installed by inserting one end of the slide rod 22 into the slide groove 24 of the mounting part 23, which is quite convenient.

[0031] In some technical solutions, such as Figure 1 As shown, support legs 15 are fixedly connected to the four corners of the bottom of the outer casing 1, and anti-slip pads are provided on the bottom of the support legs 15.

[0032] When in use, the anti-slip pads on the bottom of the support legs 15 increase the stability of the aging furnace.

[0033] Working principle: During use, the testing devices to be aged are placed in the placement tray 11. The air pump 14 delivers air from the aging testing chamber 8 to the electric heating box 13 through the exhaust pipe 10. The electric heating box 13 heats the air and then returns it to the aging testing chamber 8 through the air inlet pipe 9, realizing the hot air circulation function. The mesh tube 12 and several nozzles 21 blow hot air out from above the testing devices in the placement tray 11, preventing some testing devices from blocking the hot air for other testing devices. The outer casing 1 and the inner casing... The polyurethane foam filler 3 between the inner box 2 and the outer box 2 can reduce the heat transfer from the inner box 2 to the outside and reduce the heat loss inside the inner box 2. During the closing process of the door 4, the glass fiber cotton board 5 will contact the front opening of the inner box 2. The elastic force of the spring 20 causes the I-shaped part 16 and the sliding shaft 17 to move the glass fiber cotton board 5, so that the glass fiber cotton board 5 is tightly attached to the front of the inner box 2, reducing the heat transfer from the inner box 2 to the outside and further reducing the heat loss inside the inner box 2, which has a good energy-saving effect.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
