Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): an iron melting furnace, referring to fig. 1, comprises a concrete foundation 1, a furnace body groove 2 (referring to fig. 3) is arranged in the concrete foundation 1, and a furnace body 3 for melting iron is arranged in the furnace body groove 2. After the iron filings in the furnace body 3 are melted into molten iron, the furnace body 3 is taken out, and the molten iron in the furnace body is poured out for forging.

Referring to fig. 1, the concrete foundation 1 includes four side walls, the four side walls are respectively and fixedly connected with a fixing assembly 4 (refer to fig. 4), and the fixing assembly 4 includes two vertically arranged "L" -shaped plates 41 and a horizontally arranged supporting plate 42 (refer to fig. 4). The "L" shaped plate 41 comprises two mutually perpendicular side plates, one of which is perpendicularly connected to the outer side wall of the concrete foundation 1, the other of which is parallel to the outer side wall of the concrete foundation 1, and the supporting plate 42 is fixedly connected to the outer side wall of the concrete foundation 1. The support plate 42 is located below and between the two "L" shaped plates 41. The two L-shaped plates 41 and the supporting plate 42 are arranged in a U shape. An iron scrap heating box 5 is inserted in the fixing component 4, and a feeding hole for feeding in and out iron scraps is formed in the top of the iron scrap heating box 5.

Referring to fig. 1, when melting the iron fillings in the furnace body 3, heat in it can conduct on concrete foundation 1, and the heat on concrete foundation 1 conducts the iron fillings in iron fillings heating box 5 to the completion is treated the mesh that melts iron fillings preheated, realizes simultaneously the make full use of to the heat on concrete foundation 1, reduces the waste to the heat.

Referring to fig. 1, a handle 6 is fixedly connected to the top of the iron scrap heating box 5, and the handle 6 is in a U-shaped structure. When needing to add iron fillings to the furnace body 3 once more, at this moment, the iron fillings in iron fillings heating box 5 have been preheated. The lifting handle 6 is lifted upwards to enable the scrap iron heating box 5 to leave from the fixing assembly 4 (refer to fig. 4), and the scrap iron heating box is moved to the upper part of the furnace body 3 to pour the scrap iron into the furnace body 3.

Referring to fig. 4, the bottom of iron fillings heating box 5 is opened there is the discharge gate, and discharge gate department articulates there is bottom plate 8, and iron fillings heating box 5 keeps away from concrete foundation 1's lateral wall fixedly connected with backup pad 9, and backup pad 9 perpendicular to iron fillings heating box 5's lateral wall. Wear to be equipped with the dwang 10 that is vertical setting in the backup pad 9, dwang 10 rotates to be connected in backup pad 9, and the cover is equipped with rolling bearing 11 between dwang 10 and the backup pad 9 (refer to fig. 1). The bottom fixedly connected with limiting plate 12 of dwang 10, limiting plate 12 are fan-shaped structure, are the right angle structure between limiting plate 12 and dwang 10.

Referring to fig. 4, by rotating the rotating lever 10, when the restriction plate 12 is separated from the bottom plate 8, the bottom plate 8 is opened and iron pieces come out from the iron piece heating box 5. When the restriction plate 12 is located below the bottom plate 8, the bottom of the iron piece heating box 5 is closed. Therefore, the rotating rod 10 and the limiting plate 12 are matched with each other, and the opening or the closing of the bottom of the iron chip heating box 5 can be completed. The rotation bearing 11 (refer to fig. 1) reduces the friction between the rotation lever 10 and the support plate 9, and facilitates the rotation of the rotation lever 10 to complete the fixing and opening of the bottom plate 8.

Referring to fig. 4, the iron scrap heating box 5 is made of copper, and the copper has good thermal conductivity, so that heat from the concrete foundation 1 can be absorbed more quickly, and the process of quickly heating the iron scrap in the iron scrap heating box 5 is completed.

Referring to fig. 5, a heat insulation plate 14 is hinged at the feed inlet above the iron scrap heating box 5, and the hinged position is far away from the rotating rod 10. The heat insulation plate 14 can enable the scrap iron heating box 5 to form a sealed space, and the upper surface of the heat insulation plate 14 is fixedly connected with a U-shaped lifting handle 7. At the in-process that iron fillings preheated, the iron fillings heat the difficult foreign matter that exists of 5 inside and splash out under the effect of thermal energy, improved the security. Meanwhile, the heat is not easy to dissipate in the sealed space, and the preheating effect on the scrap iron is better achieved.

Referring to fig. 4, the triangular handle 13 is fixedly connected to the top of the rotating rod 10, the supporting plate 42 has a width only half of that of the bottom plate 8, and when the iron scrap heating box 5 is placed in the fixing assembly 4, the triangular handle 13 is screwed to enable the limiting plate 12 to abut against the bottom plate 8, and at this time, the limiting plate 12 does not touch the supporting plate 42. When the limit plate 12 abuts against the bottom plate 8, the triangular handle 13 abuts against the heat insulation plate 14 (see fig. 5), which has a fixing effect on the heat insulation plate 14, thereby reducing the occurrence of the accident that the heat insulation plate 14 is opened during the heating process of the suka heating box 5. Meanwhile, the triangular handle 13 can increase the acting point of the rotating rod 10, reduce the torsion and facilitate the rotation of the rotating rod 10.

The specific implementation process comprises the following steps: after iron fillings in iron fillings heating box 5 are preheated, upwards mention handle 6 and take out iron fillings heating box 5 from fixed subassembly 4, then move iron fillings heating box 5 to the top of furnace body 3 to rotatory triangle handle 13 makes bottom plate 8 separation on limiting plate 12 and the iron fillings heating box 5, thereby iron fillings after being preheated in iron fillings heating box 5 enter into in the furnace body 3.

After the iron fillings in iron fillings heating box 5 poured into furnace body 3, move iron fillings heating box 5 to fixed subassembly 4 in, then rotatory dwang 10, limiting plate 12 supports bottom plate 8 to the completion is to iron fillings heating box 5's sealed. The insulation board 14 is then opened and scrap iron to be heated is added to the scrap iron heating box 5, thereby preparing for the next preheating process.
