Description

Technical Field

[0001] This utility model relates to the field of gas valve housing processing, specifically to an aluminum melting furnace for processing gas valve housings. Background Technology

[0002] An aluminum melting furnace for gas valve housing processing is a device used to melt aluminum raw materials during the production of gas valve housings. A search revealed a fixed gas-fired aluminum melting furnace disclosed in utility model patent application number CN202121533753.0. This furnace includes an annular insulated shell with a sealing cover fixedly connected to its top. A sealing door is movably connected to the sealing cover. An aluminum melting furnace is housed within the annular insulated shell, and a stirring device is installed inside the furnace. Several vertically arranged heat-conducting pipes are positioned between the annular insulated shell and the furnace, with their bottoms interconnected. An insulation layer is filled between adjacent heat-conducting pipes. A liquid outlet is located at the bottom of the furnace, containing an automatic valve. An annular combustion chamber surrounds the liquid outlet and is fixedly connected to the bottom of the furnace. In practical applications, this utility model effectively utilizes waste heat, ensuring uniform heating of the entire furnace and eliminating the need for manual stirring, thus significantly saving manpower and resources.

[0003] However, in the aforementioned aluminum melting furnace used for processing gas valve housings, the molten aluminum is discharged from the bottom of the furnace, causing unfinished residue and waste to be discharged before the molten aluminum. This results in the finished aluminum liquid containing a significant amount of impurities, making it unsuitable for processing gas valve housings. Furthermore, while the stirring blades can accelerate the melting process, prolonged exposure to high temperatures can damage them. Therefore, improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum melting furnace for processing gas valve housings, which solves the problem that existing pulsation attenuators are prone to mixing with more impurities when discharging from the bottom, and also solves the problem that the stirring blades are easily damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum melting furnace for processing gas valve housings, comprising a housing, with connecting shafts installed on both sides of the top of the housing, the other end of the connecting shaft rotatably mounted on a support base, the support base being fixed to a base, inclined pushing mechanisms provided on both sides of the housing, a push plate vertically mounted on the bottom of the housing, an eccentric wheel provided on the side of the push plate away from the pushing mechanism, a rotating shaft mounted on the eccentric wheel, the end of the rotating shaft rotatably mounted inside a U-shaped plate, the U-shaped plate being mounted on a motor housing, the motor housing being fixed to a base, and the rotating shaft penetrating into the motor housing and connected to a drive motor, the rotating shaft being rotatably connected to the motor housing.

[0006] Preferably, the shell is a cylindrical container with an open top, and a crucible is placed inside the shell. The top of the crucible is fixedly connected to the top of the shell, forming a combustion chamber between the shell and the crucible. A gas-filling mechanism is provided on the bottom side of the shell away from the U-shaped plate. The crucible serves as a carrier for melting aluminum, loading aluminum into it. After being heated at the bottom of the crucible, the aluminum melts inside.

[0007] Preferably, a discharge pipe is provided on the top side of the shell away from the pushing mechanism. One end of the discharge pipe extends into the crucible, and the other end is fitted with a sealing cap. A guide groove is formed on the inner wall of the crucible, corresponding to the discharge pipe. Through the guide groove and the discharge pipe, when the shell is tilted, the molten aluminum can fall into the discharge pipe along the guide groove and complete the discharge, thus guiding the discharge of the aluminum liquid.

[0008] Preferably, the gas filling mechanism includes a pipe fixed to the bottom of the housing and away from the discharge pipe. A connecting pipe is installed on the side of the pipe, and a telescopic hose is installed at the other end of the connecting pipe. An air inlet pipe is installed at the other end of the telescopic hose, and the air inlet pipe is fixedly connected to the base via a fixing seat. The telescopic hose prevents damage to the gas filling mechanism due to rotation of the housing.

[0009] Preferably, an annular limiting plate is installed at the top edge of the crucible. The limiting plate limits the flow of molten aluminum to the top of the crucible when the shell is tilted, preventing the molten aluminum from spilling out.

[0010] Preferably, the pushing mechanism includes a hydraulic cylinder, the bottom of which is rotatably mounted on a support base, and a guide rod connected to the top of the hydraulic cylinder. The other end of the guide rod is slidably mounted inside a sleeve, and a rotating shaft is connected to the top of the sleeve. The rotating shaft is rotatably mounted inside a U-shaped seat with its opening facing downwards, and the U-shaped seat is fixed to the outer wall of the housing. The hydraulic cylinder provides power for pouring the molten aluminum; simultaneously, the sliding of the guide rod within the sleeve provides space for the housing to swing, thus preventing the hydraulic cylinder from obstructing the swing of the housing.

[0011] Preferably, reinforcing plates are installed on both sides of the support base, with one end of the reinforcing plate fixed to the base and the other end fixed to the reinforcing plate. The reinforcing plates improve the support strength of the support base for the shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the rotation of the eccentric wheel on the side of the push plate to push the housing together, allowing the housing to swing back and forth around the connecting shaft, thereby shaking the aluminum placed in the crucible to increase the melting rate of the aluminum.

[0014] 2. This utility model uses a pushing mechanism to tilt the housing along the connecting shaft, allowing the molten aluminum to be discharged from the discharge pipe located at the top of the housing, reducing the amount of residue in the discharged aluminum and improving the processing quality of the subsequent gas valve housing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2An aluminum melting furnace for processing gas valve housings includes a housing 1.

The support base 3 is fixed to a base 4. Inclined pushing mechanisms 26 are provided on both sides of the housing 1. Reinforcing plates 20 are mounted on both sides of the support base 3, with one end of each reinforcing plate 20 fixed to the base 4 and the other end fixed to the support base 4. The reinforcing plates 20 enhance the support strength of the support base 3 for the housing 1. The pushing mechanism 26 includes a hydraulic cylinder 13. The bottom of the hydraulic cylinder 13 is rotatably mounted on the support base 3. The top of the hydraulic cylinder 13 is connected to a guide rod 12. The other end of the guide rod 12 is slidably mounted inside the sleeve 11. The top of the sleeve 11 is connected to a rotating shaft 10. The rotating shaft 10 is rotatably mounted inside a U-shaped seat 14 with its opening facing downward. The U-shaped seat 14 is fixed to the outer wall of the housing 1. The hydraulic cylinder 13 provides power for the pouring of molten aluminum. At the same time, the sliding of the guide rod 12 inside the sleeve 11 provides space for the swinging of the housing 1, so as to avoid the setting of the hydraulic cylinder 13 from hindering the swinging of the housing 1.

[0022] Please see Figure 1 , Figure 4 The shell 1 is a cylindrical container with an open top. A crucible 15 is housed inside the shell 1, with its top fixedly connected to the top of the shell 1, forming a combustion chamber between them. A gas-feeding mechanism 25 is located at the bottom of the shell 1 on the side away from the U-shaped plate 8. The crucible 15 serves as a carrier for melting aluminum, loading it with gas. Heating the bottom of the crucible 15 melts the aluminum. The gas-feeding mechanism 25 includes a pipe 21, fixed to the bottom of the shell 1 on the side away from the discharge pipe 17. A connecting pipe 22 is installed on the side of the pipe 21, and a flexible hose 23 is installed at the other end of the connecting pipe 22. An air inlet pipe 24 is installed at the other end of the flexible hose 23, and the air inlet pipe 24 is fixedly connected to the base 4 via a fixed seat. The gas filling mechanism 25 will not be damaged due to the rotation of the housing 1 via the telescopic hose 23. A discharge pipe 17 is provided on the top of the housing 1 away from the pushing mechanism 26. One end of the discharge pipe 17 extends into the crucible 15 and the other end is fitted with a sealing cap 18. A guide groove 16 is provided on the inner wall of the crucible 15. The guide groove 16 corresponds to the discharge pipe 17. Through the guide groove 16 and the discharge pipe 17, when the housing 1 is tilted, the molten aluminum can fall into the discharge pipe 17 along the guide groove 16 and complete the discharge, thus guiding the discharge of the aluminum liquid. An annular limiting plate 19 is installed at the top edge of the crucible 15. Through the limiting plate 19, when the housing 1 is tilted, the aluminum liquid flowing to the top of the crucible 15 is limited to prevent the aluminum liquid from spilling out.

[0023] Please see Figure 3 , Figure 4A push plate 5 is vertically mounted on the bottom of the housing 1. An eccentric wheel 6 is provided on the side of the push plate 5 away from the push mechanism 26. A rotating shaft 7 is mounted on the eccentric wheel 6. The end of the rotating shaft 7 is rotatably mounted in a U-shaped plate 8. The U-shaped plate 8 is mounted on a motor housing 9. The motor housing 9 is fixed on the base 4. The rotating shaft 7 passes through the motor housing 9 and is connected to a drive motor. The rotating shaft 7 is rotatably connected to the motor housing 9.

[0024] The specific implementation process of this utility model is as follows: In use, the aluminum to be melted is placed in the crucible 15, and then natural gas and air are added to the combustion chamber through the gas supply mechanism 25 and ignited to start heating the aluminum in the crucible 15. During the heating process, the drive motor is started, and the push plate 5 is pushed intermittently as the eccentric wheel 6 rotates, so that the shell 1 swings back and forth around the connecting shaft 2, thereby shaking the aluminum in the crucible 15 and accelerating the heating and melting of the aluminum. After the aluminum melts, the drive motor is turned off and the gas supply is stopped. Then the sealing cover 18 is opened and the hydraulic cylinder 13 is started, so that the hydraulic cylinder 13 pushes the shell 1 to tilt around the connecting shaft 2, thereby pouring out the molten aluminum and completing the discharge of the aluminum liquid.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
