Description

Technical Field

[0001] The invention relates to the technical field of melting and casting furnace equipment, and in particular to a well logging and feeding double-chamber melting and casting furnace. Background Art

[0002] A melting furnace is an industrial equipment used to heat and melt recycled metal or other fusible materials and then cast them. Its basic principle is to use electricity, heat energy generated by fuel combustion, etc. to heat the material in the furnace to above the melting point, turning it into a liquid state, and then injecting the liquid material into the mold through a specific casting system, and then cooling and solidifying to form the required casting.

[0003] In the prior art, traditional melting furnaces do not have well logging, and manual feeding is required. In addition, the traditional well logging and combustion chamber are not connected, so internal metal liquid circulation cannot be achieved. The internal metal liquid temperature varies greatly and is relatively energy-consuming. It is often necessary to open the slag well to discharge materials (metal fixed waste) into it, resulting in a large amount of heat loss. The dust in the furnace will be released into the atmosphere to cause pollution, and will cause heat to be dissipated, resulting in a drop in indoor temperature. The melting of metal requires a certain temperature, which requires more dyes in the fuel furnace and a longer combustion time to raise the temperature again. Traditional melting furnaces do not have dust recovery devices, because particles larger than PM2.5 will liquefy and rise into the air, causing atmospheric pollution. Summary of the invention

[0004] The purpose of the present invention is to provide a double-chamber melting and casting furnace with logging and feeding in view of the defects and shortcomings of the prior art. The furnace is equipped with a logging device, which can realize automatic feeding without manual feeding and save costs. The metal liquid can circulate inside the melting and casting furnace to avoid frequent switching when cleaning waste slag and causing heat dissipation, thereby maintaining an efficient working temperature and reducing energy consumption. The liquefied metal particle recovery device can recycle the dust generated by the smelting waste, and the recovered dust can be sold and utilized for a second time, thereby reducing the cost of using working raw materials and increasing the company's benefits. The furnace has high inventiveness and practicality for actual use.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it comprises an automatic feeding well 1 for recycled metal, a stirring well 2, a first melting furnace 3, a second melting furnace 4, a first interconnected pipeline 5, a second interconnected pipeline 6, a third interconnected pipeline 7, a slag discharge port 8, and a fuel furnace 9; a stirring well 2 is provided below the automatic feeding well 1 for recycled metal, the stirring well 2 is connected to the first melting furnace 3 and the second melting furnace 4 through the first interconnected pipeline 5 and the second interconnected pipeline 6 respectively, the first melting furnace 3 and the second melting furnace 4 are connected to each other through the third interconnected pipeline 7, and a slag discharge port 8 is provided below the first melting furnace 3 and the second melting furnace 4, and the fuel furnace 9 is located on the right side outside the automatic feeding well 1 for recycled metal.

[0006] Furthermore, the automatic recycled metal feeding well 1 is provided with an automated fume hood device 101 which can recover particles larger than PM2.5.

[0007] Furthermore, the stirring well 2 includes a mixing chamber 201, a recovery chamber 202, a suction pump 203, and a recovery channel 204; a mixing chamber 201 is opened on the left side of the stirring well 2, a recovery chamber 202 is opened on the right side of the mixing chamber 201, a connecting recovery channel 204 is arranged between the mixing chamber 201 and the recovery chamber 202, a suction pump 203 is arranged on the upper part of the recovery chamber 202, and the suction pump 203 is located at a position inside the stirring well 2 corresponding to the external lifting well.

[0008] Furthermore, the suction pump 203 is located above the recovery chamber 202 .

[0009] Furthermore, a metal door 801 is provided outside the slag discharge port 8, and metal chains 804 are installed on the left and right edges of the metal door 801. The upper end of the metal chain 804 is connected to the motor 802 at the top, and a load-bearing box 803 is installed in the middle of the metal chain 804.

[0010] Furthermore, the fuel furnace 9 includes two identical combustion furnaces.

[0011] Working principle of the present invention: The casting furnace adopts a logging device, and the metal waste enters through the automatic feeding well 1 of the recycled metal, flows out from the lifting well and forms a metal liquid. During the logging, since the molten metal liquid in the lifting well slowly flows out to the outside, the fuel furnace 9 can heat the metal liquid in the second melting furnace 4, enter the stirring well 2 through the second interconnecting channel 6, and enter the automatic feeding well 1 of the recycled metal through the recovery channel 204 to melt the crushed metal waste. Since the smelted metal liquid will flow to the outside through the pipeline to the external mold production line; under normal temperature, after a long production line, the metal liquid will quickly reach the solidification point and form solid metal. Since metal waste slag will float up during the metal casting process, the metal door 801 is opened to remove the slag inside the smelting furnace. In order to avoid the heat loss caused by the slag removal switch of the casting furnace, an automatic smoke hood device 101 is installed outside the casting furnace. A recovery pipeline is provided on the top of the automatic smoke hood device 101, and the discarded particles larger than PM2.5 can be recycled.

[0012] After adopting the above technical scheme, the beneficial effects of the present invention are as follows: automatic material feeding can be realized without manual feeding, thus saving costs; and metal liquid can circulate inside the melting furnace, thus avoiding frequent switching when cleaning waste slag and causing heat dissipation, maintaining an efficient working temperature, and reducing energy consumption. The liquefied metal particle recovery device can recycle the dust generated by the casting waste, and the recovered dust can be sold and utilized again, thus reducing the cost of using working raw materials and increasing the company's benefits.

DETAILED DESCRIPTION

[0024] See also Figure 1-9As shown, the technical solution adopted in this specific embodiment is: automatic feeding well 1 for recycled metal, stirring well 2, first melting furnace 3, second melting furnace 4, first interconnected pipeline 5, second interconnected pipeline 6, third interconnected pipeline 7, slag outlet 8, fuel furnace 9; stirring well 2 is provided below the automatic feeding well 1 for recycled metal, stirring well 2 is connected with first melting furnace 3 and second melting furnace 4 through first interconnected pipeline 5 and second interconnected pipeline 6 respectively, first melting furnace 3 and second melting furnace 4 are connected and communicated with each other through third interconnected pipeline 7, and slag outlet 8 is provided below first melting furnace 3 and second melting furnace 4, and fuel furnace 9 is located on the right side outside automatic feeding well 1 for recycled metal. Mixing chamber 201 and recovery chamber 202 inside stirring well 2 form four internal cavities interconnected with first melting furnace 3 and second melting furnace 4 through first interconnected pipeline 5, second interconnected pipeline 6 and third interconnected pipeline 7, and metal liquid can circulate in them.

[0025] Furthermore, the automatic recycled metal feeding well 1 is provided with an automated fume hood device 101 capable of recovering particles larger than PM2.5; it can recover and reuse the particle dust to increase revenue.

[0026] Furthermore, the stirring well 2 includes a mixing chamber 201, a recovery chamber 202, a suction pump 203, and a recovery channel 204; a mixing chamber 201 is opened on the left side of the stirring well 2, a recovery chamber 202 is opened on the right side of the mixing chamber 201, a connecting recovery channel 204 is arranged between the mixing chamber 201 and the recovery chamber 202, a suction pump 203 is arranged on the upper part of the recovery chamber 202, and the suction pump 203 is located at a position inside the stirring well 2 corresponding to the external lifting well. The stirring well 2 is combined into a whole by an integrated molding process, and the mixing chamber 201 is connected to the external metal waste feeding device through the feed connection port. When the smelting furnace starts working, the metal solid waste enters the mixing chamber 201 through the feed connection port, and the metal solid waste falls into the first melting furnace 3 at the corresponding position to be burned and liquefied, and the liquid metal flows into the second melting furnace 4, and flows out to the mold from the lifting well set on the right. When the liquid metal reaches the lifting well, since the diameter of the output pipe on the right side of the lifting well is smaller than the diameter of the discharge port of the lifting well, the liquid metal flows out slowly; at this time, the suction pump 203 draws the high-temperature metal liquid back to the recovery chamber 202, and flows into the mixing chamber 201 through the recovery channel 204, and is fused and smelted with the metal solid waste inside the mixing chamber 201. Therefore, the metal solid waste can be in a high temperature state when it just enters the smelting furnace, thereby reducing the working time of the smelting furnace and reducing energy consumption.

[0027] Furthermore, the suction pump 203 is located above the recovery chamber 202. When the suction pump 203 sucks the high-temperature liquid metal in the right lifting well, the high-temperature liquid metal passes through the suction pipe and is transported to the recovery chamber 202 by the output pipe, and then flows into the mixing chamber 201 through the recovery channel 204 to merge with the metal solid waste.

[0028] A metal door 801 is provided on the outside of the slag discharge port 8, and metal chains 804 are installed on the left and right edges of the metal door 801. The upper end of the metal chain 804 is connected to the motor 802 on the top, and a weighing box 803 is installed in the middle of the metal chain 804; when it is necessary to remove slag from the internal smelting, the motor 802 works to pull up the metal door 801 through the metal chain 804, and the slag can be removed from the inside. After the slag removal is completed, the metal door 801 can be closed.

[0029] Furthermore, the fuel furnace 9 comprises two identical combustion furnaces, which can be used alternately during the flame spraying, thereby increasing the service life, making the furnace more stable and capable of operating for a long time, and improving production efficiency.

[0030] The present smelting furnace adopts a logging device. The metal waste enters through the automatic feeding well 1 of the recycled metal, flows out from the lifting well and forms a metal liquid. During the logging, since the smelted metal liquid in the lifting well slowly flows out to the outside, the fuel furnace 9 can heat the metal liquid in the second melting furnace 4, enter the stirring well 2 through the second interconnecting channel 6 and enter the automatic feeding well 1 of the recycled metal through the recovery channel 204 to melt the crushed metal waste. Since the smelted metal liquid will flow to the outside through the pipeline to the external mold production line; under normal temperature, after a long production line, the metal liquid will quickly reach the solidification point and form solid metal. Since metal waste slag will float up during the metal smelting process, the metal door 801 is opened to remove the slag inside the smelting furnace. In order to avoid the heat loss caused by the slag removal switch of the smelting furnace, an automatic fume hood device 101 is installed outside the smelting furnace. A recovery pipeline is provided on the top of the automatic fume hood device 101, and the discarded particles larger than PM2.5 can be recycled.

[0031] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
