[0026] See also Figure 1-3 A high-temperature explosion-proof vacuum drying oven includes a drying oven shell 1, a heating element 2, a vacuum element 3, and a control console 10. The heating element 2 is fixedly mounted on the rear side of the inner wall of the drying oven shell 1, the vacuum element 3 is mounted on the top of the drying oven shell 1, and the control console 10 is mounted on the outer side of the drying oven shell 1.
[0027] The drying box shell 1 is composed of three layers of materials, wherein the inner layer is stainless steel 101 and the outer layer is high temperature resistant alloy 102 . High efficiency heat insulation material 103 is filled between the stainless steel 101 and the high temperature resistant alloy 102 .
[0028] It should be noted that the high-efficiency thermal insulation material 103 may be an aerogel or a vacuum layer.
[0029] In this embodiment, a ventilation duct 4 is installed near the bottom of the drying box housing 1 on a side away from the console 10 , and an electric valve is installed in the ventilation duct 4 .
[0030] It should be noted that the design of the ventilation duct 4 allows gas, such as inert gas such as nitrogen, to be introduced into the drying box under certain circumstances to protect the internal items from oxidation or perform other gas treatments. The installation of the electric valve enables the ventilation process to be precisely controlled, thereby improving the flexibility and safety of the operation.
[0031] In this embodiment, the vacuum element 3 is fixed to the middle of the top surface of the drying box shell 1 with inverted bolts, and one end of the exhaust pipe is fixedly installed at the output end of the vacuum element 3. The other end of the exhaust pipe passes through the top plate of the drying box shell 1 and is welded to the gas collecting hood 5.
[0032] It should be noted that the inverted installation of the vacuum element 3 helps to more effectively extract the gas in the drying box to form a low-oxygen or vacuum environment. The design of the gas collecting hood 5 increases the suction area, improves the vacuuming efficiency, and ensures the rapid stabilization of the environment in the drying box.
[0033] In this embodiment, a plurality of heating pipes 6 are installed on the front side of the heating element 2 . The plurality of heating pipes 6 are evenly distributed in the vertical direction, and a mounting plate 7 is fixed to the outside of the heating pipes 6 by bolts.
[0034] It should be noted that the equidistant distribution of multiple groups of heating pipes 6 ensures uniform distribution of heat in the drying box, avoiding local overheating or uneven temperature problems. The mounting plate 7 not only provides a stable support for the heating pipes 6, but also facilitates the installation and maintenance of the heating system.
[0035] In this embodiment, both sides of the mounting plate 7 are fixed to the inner wall of the drying box housing 1 by bolts, and an explosion-proof plate 8 is also adhered to the inner wall of the drying box housing 1 .
[0036] It should be noted that the addition of the explosion-proof plate 8 further improves the safety of the drying box and can prevent explosion accidents caused by excessive internal pressure in extreme cases.
[0037] In this embodiment, two sets of temperature sensors 9 are installed on the rear of the inner wall of the drying box shell 1 and on both sides of the heating element 2. The control console 10 is welded to the side of the drying box shell 1 and has two sets of control modules arranged inside it.
[0038] It should be noted that the two groups of control modules in the console 10 are used to control gas and temperature respectively.
[0039] In this embodiment, a sealing plate 11 is hingedly connected to the drying box shell 1 on the side close to the console 10, and a sealing ring is installed on the side of the sealing plate 11 facing the drying box shell 1. A lock body and a handle 12 are installed at the connection between the sealing plate 11 and the drying box shell 1 away from the hinge.
[0040] It should be noted that the design of the sealing plate 11 allows the user to easily open and close the drying box, making it easier to put items in and out. The use of the sealing ring ensures good sealing between the sealing plate 11 and the drying box housing 1, preventing gas leakage.
[0041] Beneficial effects:
[0042] The drying box shell 1 adopts a three-layer structure. The inner layer of stainless steel 101 ensures corrosion resistance, the outer layer of high-temperature resistant alloy 102 enhances the overall high-temperature resistance, and the high-efficiency thermal insulation material 103 filled in the middle effectively reduces heat transfer and improves energy utilization efficiency. In addition, the heating element 2 is combined with multiple groups of equidistantly distributed heating pipes 6 to achieve heating uniformity and ensure the consistency of the drying effect.
