Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnaces, in particular to a smelting furnace which is easy to discharge slag. Background Art

[0002] A smelting furnace is a device used to smelt metals. Currently, common smelting furnaces are divided into two categories. One is a smelting furnace heated by electricity, which has a high cost but a fast smelting speed and can smelt metals with high melting points. The other is a traditional smelting furnace that uses wood or coal for smelting. It has a low cost and can be used outdoors, but can only smelt metals with lower melting points. It is generally used for aluminum smelting and is also the most common smelting furnace.

[0003] For smelting furnaces that burn wood or coal, the residues after burning need to be cleaned after smelting. This process is mostly done manually. The residues in the furnace are shoveled out manually with a shovel. It is troublesome and time-consuming to clean up, and it is easy to cause carbon slag dust to float in the air, affecting the health of workers.

[0004] Therefore, a smelting furnace with easy slag removal is proposed. Summary of the invention

[0005] The utility model aims to provide a smelting furnace with easy slag discharge to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a smelting furnace with easy slag discharge, comprising a shell, a retaining frame is installed in the middle of the inner side of the shell, and a filter screen is installed at the bottom of the retaining frame; a limiting slide rail is installed on the lower surface of the retaining frame;

[0007] The interior of the limiting slide rail is slidably connected with a frame body, and the upper surface of the frame body is evenly provided with protrusions.

[0008] Preferably, a collection box for collecting waste residues is slidably connected to the bottom of the shell.

[0009] Preferably, one side of the frame body passes through one side of the shell and is provided with a handle, and a limiting plate is provided on the handle.

[0010] Preferably, a crucible is installed on the top of the shell.

[0011] Preferably, a feed inlet is provided on an upper side of the shell.

[0012] Preferably: a door body is installed on one side of the feed inlet.

[0013] Preferably, the inner side of the enclosure frame is provided with an inclined portion for facilitating the fuel to fall onto the filter screen.

[0014] Preferably, the top of the protrusion is provided with a rounded corner portion to prevent the scraping ring filter screen.

[0015] Compared with the prior art, the beneficial effect of the utility model is that the frame and the protrusion are moved by pulling the handle back and forth, and the lower surface of the filter is scraped by the protrusion, so that the ash and waste residue quickly fall into the collection box, avoiding the accumulation of ash and waste residue on the filter net, facilitating subsequent collection and processing, and eliminating the manual cleaning process.

[0020] 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. Example

[0021] See also Figure 1-3 The utility model provides a technical solution: a smelting furnace with easy slag discharge, comprising a shell 1, a retaining frame 7 is installed in the middle of the inner side of the shell 1, and a filter screen 8 is installed at the bottom of the retaining frame 7; a limiting slide rail 9 is installed on the lower surface of the retaining frame 7;

[0022] A frame body 10 is slidably connected inside the limiting slide rail 9 , and protrusions 11 are evenly arranged on the upper surface of the frame body 10 .

[0023] like Figure 1 and Figure 2 As shown: the bottom of the shell 1 is slidably connected with a collection box 5 for collecting waste residues; through the above arrangement, the generated waste residues will fall into the interior of the collection box 5, thereby facilitating centralized treatment of the waste residues.

[0024] like Figure 1 and Figure 3As shown: one side of the frame 10 passes through one side of the shell 1 and is installed with a handle 6, and a limit plate 61 is provided on the handle 6; through the above arrangement, the handle 6 can more conveniently pull the frame 10 to move, and the limit plate 61 can limit the position of the frame 10 on the one hand, and can also block the hole on the other hand.

[0025] like Figure 1 and Figure 2 As shown: a crucible 2 is installed on the top of the shell 1.

[0026] like Figure 1 As shown: a feed port 3 is opened on the upper side of the shell 1, and a door body 4 is installed on one side of the feed port 3; through the above arrangement, the feed port 3 is used to add fuel to the inside and is sealed by the door body 4 to avoid heat loss.

[0027] like Figure 2 As shown: the inner side of the enclosure frame 7 is provided with an inclined portion 71 for facilitating the fuel to fall onto the filter screen 8; through the above arrangement, the fuel and waste residue can be concentrated on the filter screen 8.

[0028] like Figure 2 and Figure 3 As shown: the top of the protrusion 11 is provided with a rounded corner portion to prevent the filter screen 8 from being scraped; through the above arrangement, the filter screen 8 can be prevented from being damaged when the protrusion 11 scrapes the filter screen 8.

[0029] Working principle: fuel is added into the interior through the feed port 3, and then the objects inside the crucible 2 are melted. After the fuel burns for a long time, a large amount of ash and waste residue will be accumulated on the filter screen 8 and cannot fall into the collection box 5, thereby affecting the subsequent combustion and heating work.

[0030] At this time, the frame 10 is moved by pulling the handle 6, so that the protrusion 11 moves back and forth on the lower surface of the filter screen 8, and the protrusion 11 scrapes the lower surface of the filter screen 8, so that the ash and waste residue can quickly fall into the inside of the collection box 5, eliminating the manual cleaning process and improving work efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
