Description

Technical Field

[0001] The present invention relates to the technical field of aluminum processing, and particularly to an aluminum profile smelting furnace. Background Art

[0002] A smelting furnace refers to a furnace for melting iron ore, such as melting hematite (Fe2O3) or magnetite (Fe3O4) to turn it into pig iron. This furnace body is a tall cylindrical structure lined with refractory materials. Washed ore, coke, and a solvent (usually limestone) are filled in from the top. The conversion of iron oxide to metallic iron is a reduction process, in which carbon monoxide and hydrogen are used as reducing agents. Nowadays, more and more aluminum profile processing plants also use smelting furnaces to smelt aluminum profiles according to usage requirements. However, there are certain drawbacks in some small smelting furnaces on the market. That is, after smelting is completed, the operator needs to use tongs to take out the inner furnace containing the aluminum profile and then pour the aluminum profile into the mold.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 6 , the present invention provides a technical solution:

[0027] An aluminum profile smelting furnace, such as Figures 1-6 As shown, it includes a base 1, a pair of support plates 6 are symmetrically fixedly installed on the top surface of the base 1, the inner sides of the pair of support plates 6 are fixedly connected to the smelting furnace body 3 through a rotating shaft, and the side surfaces of the pair of support plates 6 are opened with arc grooves 10, and a connecting rod 22 is slidably connected inside the arc groove 10, one end of the connecting rod 22 is fixedly connected to the bottom end of the smelting furnace body 3, and the other end of the connecting rod 22 is fixedly connected to the handle 12, and a limiting rod 19 is fixedly installed on one side of the inner bottom surface of the smelting furnace body 3, and the top of the limiting rod 19 is connected to the top surface of the smelting furnace body 3, and the other side of the inner bottom surface of the smelting furnace body 3 is fixedly connected with a threaded rod 4 through a rotating shaft, the end of the threaded rod 4 passes through the top surface of the smelting furnace body 3 and is fixedly connected with a crank 5, the surface of the threaded rod 4 and located inside the smelting furnace body 3 is threadedly connected with an inner furnace 18, and the threaded rod 4 and the limiting rod 19 both pass through the inner furnace 18, and a discharge port 2 is provided on the outside of the smelting furnace body 3.

[0028] By adopting the above technical solution, the aluminum profile can be placed in the inner furnace 18, the smelting furnace body 3 is started, and it is smelted. After the smelting is completed, the crank 5 is manually turned, and the inner furnace 18 is lifted upward by rotating the threaded rod 4 until the leak on the side of the inner furnace 18 coincides with the discharge port 2 on the smelting furnace body 3, and then the handle 12 is manually pulled and pulled upward along the running trajectory of the arc groove 10, so that the smelting furnace body 3 is tilted, thereby pouring the smelted aluminum profile in the inner furnace 18 out of the smelting furnace body 3.

[0029] Specifically, Figure 1 As shown, a plurality of pairs of threaded holes 7 are provided on the side of the base 1 , and a pair of handles 8 are threadedly connected inside one pair of threaded holes 7 .

[0030] By adopting the above technical solution, the height of a pair of handles 8 can be adjusted accordingly through the threaded holes 7 according to the height of the operator, thereby providing a more comfortable point of force for the operator, making it easier to move the device.

[0031] Specifically, Figure 1 As shown, two pairs of universal wheels 13 are symmetrically fixedly installed at the bottom of the base 1, and a foot cup 11 is fixedly installed at the bottom of the base 1 and between each pair of universal wheels 13, and an anti-slip pad is arranged at the bottom of the foot cup 11.

[0032] By adopting the above technical solution, the device is moved by rotating the universal wheel 13, so that the flexibility of the device is increased, and the foot cup 11 is manually rotated until the bottom of the foot cup 11 contacts the ground, thereby fixing the position of the device by increasing the friction between the two.

[0033] Specifically, Figure 1As shown, a heat insulation pad is provided at the end of the crank handle 5, and the surface of the end of the crank handle 5 is uneven.

[0034] By adopting the above technical solution, the operator can rotate the crank handle 5 more easily, and the high temperature generated by the device will not be conducted to the crank handle 5 and then cause damage to the operator.

[0035] Specifically, as Figure 4 shown, both the limit rod 19 and the threaded rod 4 are made of steel.

[0036] By adopting the above technical solution, due to the characteristic that the melting point of the steel material is higher than that of the aluminum material, it can be ensured that the limit rod 19 and the threaded rod 4 can work stably without being affected by the high temperature inside the smelting furnace body 3.

[0037] Specifically, as Figure 1 shown, on the top surface of the base 1 near the grip 8, a plurality of pairs of equally spaced heat insulation plates 20 are symmetrically and fixedly installed. The distance between the heat insulation plates 20 is 0.5 - 1.5 mm, the thickness of the heat insulation plates 20 is 0.5 - 1 mm, liquid water is filled between adjacent heat insulation plates 20, arc-shaped grooves 10 are opened on the side surfaces of the heat insulation plates 20, a connecting rod 22 is slidably connected inside the arc-shaped grooves 10, one end of the connecting rod 22 is fixedly connected to the bottom end of the smelting furnace body 3, and the other end of the connecting rod 22 is fixedly connected to a pull handle 12. By setting the connecting rod 22 to connect the pull handle 12 and the bottom end of the smelting furnace body 3, the fixing effect can be improved to ensure the safety performance of the present invention.

[0038] By adopting the above technical solution, by pulling the pull handle 12 to slide along the arc-shaped groove 10, first the connecting rod 22 will be driven to slide correspondingly, and the connecting rod 22 will drive the smelting furnace body 3 to tilt, so that the smelted aluminum material can be unloaded from the smelting furnace body 3. By setting a plurality of pairs of equally spaced heat insulation plates 20, the heat insulation effect can be improved to avoid scalding the user due to the high temperature heat generated by the smelting material.

[0039] Specifically, as Figure 2 and Figure 3 shown, a square groove 16 is opened on the side surface of the pull handle 12, sliding grooves 14 are opened on both inner walls of the square groove 16, springs 17 are fixedly installed on the inner walls of a pair of sliding grooves 14, a fixing pin 15 is slidably connected between the pair of sliding grooves 14, the end of the spring 17 is connected to the fixing pin 15, and a plurality of limit holes 9 adapted to the fixing pin 15 are opened on both sides of the pair of support plates 6 and on both sides of the arc-shaped groove 10.

[0040] By adopting the above technical solution, the fixing pin 15 on the pull handle 12 can be manually pulled and the pull handle 12 can be moved along the running track of the arc-shaped groove 10, so that the smelting furnace body 3 can be tilted. Then, the fixing pin 15 is released, and the end of the fixing pin 15 is pushed into the limiting hole 9 by the pushing force of a pair of springs 17, thereby fixing the position of the smelting furnace body 3.

[0041] Specifically, annular plates 27 are arranged at intervals between the heat insulation plates 20. The annular plates 27 are fixedly coaxially installed on the connecting rod 22, and the thickness of the annular plates 27 is 0.5-1 mm. The annular plates 27 are provided to improve the safety performance of the device; the surfaces of the heat insulation plates 20 are uneven. By providing the heat insulation plates 20 with uneven surfaces, the contact area between the heat insulation plates 20 is increased, and the water storage capacity between the heat insulation plates 20 is improved. A placement box 21 is fixedly installed at the upper end of the heat insulation plate 20. A sponge block 23 is placed in the placement box 21. The sponge block 23 is used to store water. A water injection pipe 24 is fixedly connected to the upper surface of the placement box 21. A water injection joint 25 is fixedly connected to the inner wall of the water injection pipe 24; the placement box 21, the sponge block 23, the water injection pipe 24 and the water injection joint 25 together form a water injection device, and the water injection device is provided to inject water between the heat insulation plates 20.

[0042] By adopting the above technical solution, the annular plates 27 are installed to increase the adsorption force between the plate members when water passes through. Correspondingly, the resistance to relative sliding between the plate members increases, which can buffer the falling speed of the smelting furnace body 3 when it slips due to the user's operation error, and prevent the user from being scalded by the splashing of high-temperature aluminum profiles; during use, water is injected into the placement box 21 through the water injection pipe 24. The water entering the placement box 21 is first absorbed by the sponge block 23, and the sponge block 23 will further seep water onto the heat insulation plate 20. The sponge block 23 is provided to store water, playing a certain role in saving water. Under the action of water, the adsorption force between the heat insulation plate 20 and the connecting rod 22 and the arc-shaped groove 10 will increase accordingly, so that the resistance increases accordingly, improving the safety of the device. Correspondingly, the water between some of the heat insulation plates 20 will evaporate and absorb heat after absorbing heat, improving the heat insulation effect of the heat insulation plate 20.

[0043] Working principle: By manually turning the crank handle 5, the threaded rod 4 is driven to rotate. Since the inner furnace 18 is threadedly connected to the surface of the threaded rod 4, the inner furnace 18 will be lifted upward under the restriction of the limiting rod 19 until the leakage opening on the inner furnace 18 coincides with the discharge port 2 on the smelting furnace body 3. Subsequently, manually pull the pull handle 12 and move it upward along the running track of the arc-shaped groove 10. Since the smelting furnace body 3 is connected to a pair of support plates 6 through a rotating shaft, the smelting furnace body 3 will tilt as the pull handle 12 moves until the smelted aluminum profiles in the inner furnace 18 are poured out of the smelting furnace body 3. During the unloading process, water is injected into the placement box 21 through the water injection pipe 24. The water entering the placement box 21 is first absorbed by the sponge block 23, and the sponge block 23 will further seep water onto the heat insulation plate 20. Under the action of water, the adsorption force between the heat insulation plate 20, the connecting rod 22 and the arc-shaped groove 10 will be correspondingly increased, thereby preventing accidents caused by the fixing pin 15 slipping off due to improper operation by the user, resulting in the fall of the smelting furnace body 3, and greatly improving the safety performance of the device.

[0044] Usage method: Before use, place the aluminum profiles in the inner furnace 18, and the smelting furnace body 3 smelts them. After smelting, manually turn the crank handle 5, which drives the threaded rod 4 to rotate, thereby lifting the inner furnace 18 upward until the leakage opening on the inner furnace 18 coincides with the discharge port 2 on the smelting furnace body 3. Subsequently, manually pull the fixing pin 15 on the pull handle 12 and move the pull handle 12 upward along the running track of the arc-shaped groove 10. The pull handle 12 drives the smelting furnace body 3 to tilt, thereby pouring the smelted aluminum profiles in the inner furnace 18 out of the smelting furnace body 3. When the fixing pin 15 is released, under the driving force of a pair of springs 17, the end of the fixing pin 15 is inserted into one of the pairs of limiting holes 9, and the position of the smelting furnace body 3 can be fixed, thus liberating the operator's hands. During use, water is injected between the heat insulation plates 20 through the water injection device. Under the action of the sponge block 23, the water will penetrate and adsorb on the heat insulation plate 20 with uneven surfaces, as well as between the connecting rod 22 and the arc-shaped groove 10, thereby increasing the adsorption force and improving the overall safety of the device.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
