The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-6 The present invention provides a multifunctional melting furnace device, comprising: a furnace body 1, a take-out rack 4 and a crucible rack 6. A furnace door 2 is mounted on the opening of the furnace body 1, and a melting crucible 3 is sleeved on the top of the furnace body 1.

[0035] The furnace body 1 includes a large internal cavity and a small crucible heating cavity at the top, and an electric heating device is installed on the bottom inner wall of the furnace body.

[0036] The furnace body 1 includes an outer shell 11, a furnace wall 14 is installed inside the outer shell 11, a bottom furnace opening 15 is opened at the front end of the furnace wall 14, and the inside of the bottom furnace opening 15 is sleeved on the outside of the furnace door 2. The furnace door (2) and the outer shell (11) are connected by a sliding device;

[0037] The sliding device includes a sliding frame 21, which can slide forward and backward along the housing 11. The front end of the sliding frame 21 is equipped with a fixed shaft 24, the outer side of the fixed shaft 24 is hinged with a hinge 25, and the rear of the hinge 25 is equipped with a furnace door (2).

[0038] The removal frame 4 includes a first clamping ring 41 and a second clamping ring 44 . The front ends of the first clamping ring 41 and the second clamping ring 44 are welded with a connecting rod structure and a handle structure. The first clamping ring 41 and the second clamping ring 44 can be clamped on the outer top of the melting crucible 3 .

[0039] The present invention provides a furnace with a top heating crucible capable of melting a small amount of metal and a large furnace body at the bottom for melting large pieces of metal. When in use, a heating coil 17 with a heating function at the top of the furnace body 1 can heat the melting crucible 3 and melt the metal inside the melting crucible 3. The metal rod can also be directly inserted into the center of the heating coil 17 to heat the metal rod for easy processing. Large pieces or large amounts of metal can also be placed inside the large cavity inside the furnace body for melting. It has multiple functions and is easy to use. It also has a removal rack 4 that is easy to use and will not fall off, and the melting crucible 3 can be picked up and taken out for easy casting. It effectively solves the problems of troublesome and inconvenient use caused by the use of equipment of different powers in existing non-standard processing factories.

[0040] Furthermore, support bars 13 are welded to the interior of the outer shell 11. The inner side of support bars 13 has anchor structures embedded in the interior of the furnace wall 14. The support bars 13 and anchor structures facilitate the assembly of the outer shell 11 onto the exterior of the furnace wall 14, beautifying the furnace wall 14 while also supporting and enveloping the furnace wall 14 for easy handling.

[0041] Furthermore, fireproof cotton is filled between the outer shell 11 and the furnace wall 14 to prevent the outer shell 11 from being burned, thereby improving safety performance and also having the effects of anti-collision and heat preservation during transportation.

[0042] Furthermore, a sleeve 12 is formed at the top of the outer shell 11 and the furnace wall 14 , and the sleeve 12 is sleeved on the outside of the melting crucible 3 .

[0043] Furthermore, a heating coil 17 is installed inside the furnace wall 14, and a coil for electric heating is also installed at the bottom of the furnace body 1. Heating by spraying materials such as fuel can also be used.

[0044] Furthermore, a gasket 16 is integrally formed on the top of the top sleeve 12 of the furnace wall 14, and the height of the gasket 16 is greater than the thickness of the shell 11. The gasket 16 is used to hold up the melting crucible 3 to facilitate the socketing and use of the take-out rack 4.

[0045] Furthermore, the outer surface of the sliding frame 21 is sleeved with a fixed block 22, and the inner side of the fixed block 22 is assembled on the outside of the shell 11. The interior of the hinge 25 is assembled with a furnace cover 26, and the outer surface of the furnace cover 26 is assembled with a handle 27. The number of furnace covers 26 used is two sets, and the outer surface of one set of furnace covers 26 is welded with a sealing edge 28, and the inner surface of the furnace cover is provided with a blocking block made of the same material as the furnace wall. When using the furnace cover 26, first unlock the locking mechanism, pull the two outermost handles 27, and drive the sliding frame 21 to slide outward inside the fixed block 23, thereby pulling out the blocking block that seals the bottom furnace opening 15, and finally pull the inner handle 27 to open the furnace cover 26. The blocking effect is good and the opening and closing are convenient. A simple latch structure is assembled at the front end of the furnace cover 26 and the furnace wall 14.

[0046] Furthermore, the melting crucible 3 includes a solution chamber 31 , a base 32 is integrally formed on the outside of the solution chamber 31 , and a clamping ring 33 is integrally formed on the outer side of the top end of the base 32 .

[0047] Furthermore, the outer ends of the first clamping ring 41 and the second clamping ring 44 are welded to a first connecting rod 43 and a second connecting rod 45, respectively. A baffle 49 is welded to the interior of each of the first and second connecting rods 43 and 45. An insertion slot 46 is defined on the exterior of the second connecting rod 45. A sleeve 47 is sleeved onto the exterior of the first connecting rod 43, with a socket 48 defined on one side of the sleeve 47. A first handle 410 and a second handle 411 are welded to the outer ends of the first and second connecting rods 43 and 45, respectively. The ends of the first and second clamping rings 41 and 44 are hingedly connected by a hinge shaft 42. The design of the removal rack prevents the molten crucible from falling off the rack while also saving effort, making it easier for workers to pick up and remove the molten crucible for casting.

[0048] It should be noted that during use, after rotating the sleeve 27 to align the socket 48 with the insertion groove 46, the second connecting rod 45 can be removed from the interior of the sleeve 27, thereby opening and closing the clamping ring structure. After closing, the sleeve 27 is moved to the position of the stopper 49, thereby realizing a grippable handle structure. By rotating the assembled handle, it is convenient to pour the molten metal.

[0049] Furthermore, the bottom end of the removal rack 4 is equipped with an auxiliary bracket 5. The auxiliary bracket 5 is a bracket used to assist the removal rack 4 and is mainly used for removing equipment after the bottom end of the furnace body 1 is heated. A crucible structure is also required when heating the bottom end of the furnace body 1, and the size of the crucible sleeved inside the crucible rack 6 is used according to the actual required size. The top of the auxiliary bracket 5 has a four-column-shaped claw structure. After the combined connecting rod structure of the removal rack 4 is placed inside, it is convenient to rotate and pour the molten metal. The removal rack 4 can be made in various sizes according to the size of the crucible.

[0050] According to the above technical features, the working principle of the multifunctional melting furnace equipment provided by this application in actual application scenarios is as follows:

[0051] During use, a heating coil 17 at the top of the furnace body 1 heats the crucible 3, melting the metal inside. Alternatively, a metal rod can be directly inserted into the center of the heating coil 17 to heat it for easier processing. Large blocks or quantities of metal can also be melted within the large cavity within the furnace body. This versatile and convenient operation features a convenient, non-detachable removal rack 4 for lifting and removing the crucible 3 for easy casting.
