[0002] Aluminum alloy quenching furnace is suitable for solution heat treatment and aging treatment of large and medium-sized aluminum alloy product parts. In the production of gray cast iron, the quenching material rack in the aluminum alloy quenching furnace is generally used to collect and store the quenching material for subsequent processing of the gray cast iron. The existing quenching furnace is usually equipped with a heating device, which heats the quenching furnace to melt the gray cast iron.

[0003] The existing heating device adopts hot air circulation, that is, the heat emitted by the resistance belt is circulated through hot air circulation to make the temperature in the furnace uniform. However, the hot air circulation in the existing heating device cannot keep the quenching furnace warm. When heating is performed again, there is a difference in temperature between the furnace wall and the furnace, which increases the heating time of the quenching furnace, reduces the efficiency of the quenching process, and affects the practicality of the heating device.

[0004] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content

[0011] Furthermore, a handle is fixed to the top of the first mounting net ring, and an insulating ring is sleeved on the outside of the handle. The setting of the handle is conducive to a larger force-bearing area between the user and the handle, which makes it easier to apply force, thereby increasing the torque when the handle rotates, thereby achieving the purpose of accelerating adjustment.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] The utility model provides Figure 1A heating device for an aluminum alloy quenching furnace is shown, comprising: a base 1, a quenching furnace body 11 is installed on the top of the base 1; as can be seen from the above, when in use, when the quenching furnace is heated, the quenching furnace body 11 is fixedly installed with the base 1 to provide a stable support for the quenching furnace body 11, and the heat emitted by the resistance belt is thermally circulated through the hot air circulation in the quenching furnace body 11 to make the temperature in the furnace uniform, which is used for melting and casting gray cast iron raw materials for subsequent processing of the gray cast iron raw materials.

[0028] refer to Figure 1-Figure 4 As shown, the heating assembly 2 is used to heat and keep the quenching furnace body 11 warm. The heating assembly 2 includes a heating base 21 sleeved on the outside of the quenching furnace body 11 and a mounting ring 22 fixed on the heating base 21, and a heating cavity is formed between the mounting ring 22 and the quenching furnace body 11. A heating resistor ring 23 is installed on the heating base 21, and the heating resistor ring 23 is located in the heating cavity. A temperature control assembly for discharging the temperature in the heating cavity is provided on the mounting ring 22; the temperature control assembly includes a mounting seat 24 fixed on the mounting ring 22 and a detachable mounting member 24 mounted on the mounting seat 24, and the mounting frame 25 is located in the heating chamber, the mounting frame 25 is installed with a second mounting net ring 28, and the top of the second mounting net ring 28 is rotatably installed with a first mounting net ring 26; the top of the first mounting net ring 26 is also fixed with a handle 27, and the outside of the handle 27 is sleeved with a heat insulating ring; a clamping assembly is arranged between the mounting seat 24 and the mounting frame 25, and the clamping assembly includes a fixing block 29 fixed to the outside of the mounting frame 25 and a clamping groove opened on the inner wall of the mounting seat 24, and the fixing block 29 is clamped and fixed with the clamping groove.

[0029] Through the above technical solution:

[0030] When in use, the fixing block 29 is inserted into the clamping groove to push the mounting bracket 25 downward. During the downward movement of the mounting bracket 25, the outer wall of the mounting bracket 25 is squeezed between the quenching furnace body 11 and the mounting seat 24, so that the mounting bracket 25 is squeezed and fixed between the quenching furnace body 11 and the mounting seat 24, which is used to seal the heating chamber, and the normal power supply of the heating resistor coil 23 and the heating base 21 causes the surface temperature of the heating resistor coil 23 to continue to rise. However, the temperature generated on the surface of the heating resistor coil 23 is all located in the heating chamber, which is used to heat the outer wall of the quenching furnace body 11, and can heat and keep the outer wall of the quenching furnace body 11 warm, so that the outer wall of the quenching furnace body 11 maintains a normal temperature, thereby solving the problem that when the existing quenching furnace is heated again, there is a temperature difference between the furnace wall and the furnace, which leads to an increase in the heating time of the quenching furnace. When the quenching furnace body 11 is heated again, the interior can be quickly heated up.

[0031] At the same time, when the temperature in the heating chamber is too high, the handle 27 is held and rotated. At this time, the rotation of the handle 27 drives the first mounting net ring 26 to rotate and adjust along the second mounting net ring 28. When the first mounting net ring 26 rotates along the second mounting net ring 28, the meshes on the first mounting net ring 26 and the meshes on the second mounting net ring 28 are intertwined, and the gap between the two is freely adjusted under the continuous movement of the first mounting net ring 26. When the meshes of the first mounting net ring 26 and the second mounting net ring 28 overlap, the gap between them is maximized, which is used to allow the external air to interact with the heating chamber, so as to accelerate the heat dissipation of the temperature in the heating chamber and improve the practicality of the heating device.

[0032] In addition, refer to Figure 1-Figure 3 as well as Figure 5 As shown, a blocking component 3 is provided on the mounting seat 24, and the blocking component 3 includes a plug-in block 31 slidably connected in the card slot and a connecting block 33 fixed on one side of the plug-in block 31, a supporting frame 34 is fixed at the bottom end of the connecting block 33, a grid blocking ring 35 is installed on the supporting frame 34, and the grid blocking ring 35 is located in the heating chamber, and a fixing component for positioning it with the plug-in block 31 is provided in the card slot; the fixing component includes a positioning slot opened in the card slot and a positioning block 32 fixed at the bottom end of the plug-in block 31, and the positioning block 32 is plugged and installed between the positioning slot.

[0033] Through the above technical solution:

[0034] When in use, when the quenching furnace is heated, the support frame 34 is pushed downward by inserting the plug-in block 31 into the card slot. When the support frame 34 moves downward, the plug-in block 31 is driven to move synchronously along the card slot. The card slot is used to limit the plug-in block 31 to prevent the plug-in block 31 from shifting during movement, and the positioning block 32 is inserted into the positioning slot. When the positioning block 32 conflicts with the positioning slot, the user cannot push the support frame 34, which is used to prompt the user, maximize the movement of the support frame 34, and the fixing block 29 is inserted into the card slot and conflicts with the plug-in block 31, thereby enhancing the stable installation of the support frame 34. At this time, the grid retaining ring 35 is located in the heating chamber, but the grid retaining ring 35 and the first mounting mesh ring 26 and the second mounting mesh ring 28 form a double-layer structure with each other, which can filter and protect the heating chamber, prevent foreign particles and impurities from falling into the heating chamber, thereby affecting normal heating, and improving the practicality of the heating device.

[0035] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, as well as any modification, equivalent replacement and improvement made, are within the protection scope of the present invention.
