Description

Technical Field

[0001] This utility model relates to the field of crucible furnaces, and more particularly to a furnace chamber structure for a crucible furnace. Background Technology

[0002] A crucible furnace is a heating device that uses a crucible as a melting container. It is widely used in the melting of metals (such as aluminum ingots, copper, zinc, gold, and silver), alloy preparation, laboratory research, and small-scale casting. A crucible furnace generally includes a crucible, a furnace chamber, a combustion chamber, and a burner. The burner provides heat to the furnace chamber and directly heats the sides and bottom of the crucible with flame jets. However, the burner's configuration and jet nozzle structure are simple, and the crucible is heated unevenly, affecting the heating effect. Therefore, it is necessary to design a new crucible furnace chamber structure to solve the above problems. Utility Model Content

The multiple conveying pipe seats are correspondingly connected to the multiple mounting ports. Multiple burners are correspondingly fixed in the multiple mounting ports. A gas pipe is provided on the rear side of the middle of the burner, and the gas pipe is connected to the furnace chamber through multiple gas channels. The burner has gas delivery channels on the left and right sides of the multiple gas channels, and the gas delivery channels are connected to the furnace chamber through multiple branch pipes.

[0005] Preferably, a furnace base is provided on the bottom surface of the furnace chamber, and the crucible is fixed on the furnace base of the furnace chamber.

[0006] Preferably, a conveying pipe is provided inside the conveying pipe seat, and a connecting seat is provided between the conveying pipe seat and the installation port in the furnace body. The connecting seat is provided with connecting pipes that are respectively connected to the gas supply channels of the conveying pipe and the burner.

[0007] Preferably, a distribution box communicating with multiple gas passages is provided on the rear side of the burner, and the gas pipe is connected to the distribution box.

[0008] Preferably, the multiple branch pipes of the two gas delivery channels of the burner are arranged at an inward angle.

[0009] The beneficial effects of this utility model are as follows: the furnace structure of the crucible furnace is achieved through the cooperation of the furnace body, crucible and burner, so that the furnace body is provided with multiple installation ports, multiple burners are correspondingly installed in multiple installation ports, multiple gas passages on the burner transport gas, and the gas supply passage of the burner transports hot air through multiple branch pipes, thereby forming multiple flame jets, which enables the gas to burn completely and reduces the emission of harmful gases, increases the heating area of ​​the crucible and improves the heating effect and service life of the crucible.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0017] like Figures 1 to 5As shown, a furnace chamber 4 structure of a crucible 2 furnace includes a furnace body 1, a crucible 2, and a burner 3. The furnace body 1 is provided with a furnace chamber 4. The top surface of the furnace body 1 is provided with multiple conveying pipe seats, and the furnace body 1 is provided with multiple mounting ports 5 communicating with the furnace chamber 4 at the right side of the furnace chamber 4. The multiple conveying pipe seats are correspondingly connected to the multiple mounting ports 5. The multiple burners 3 are correspondingly fixed in the multiple mounting ports 5. A gas pipe 6 is provided on the rear side of the middle of the burner 3, and the gas pipe 6 is connected to the furnace chamber 4 through multiple gas channels 7. The burner 3 is provided with gas supply channels 8 on the left and right sides of the multiple gas channels 7, and the gas supply channels 8 are connected to the furnace chamber 4 through multiple branch pipes 9.

[0018] The working principle of the furnace chamber 4 of the crucible 2 furnace described in this utility model is achieved through the cooperation of the furnace body 1, the crucible 2, and the burner 3. Figures 1 to 5 As shown, the furnace body 1 is provided with multiple mounting ports 5, and multiple burners 3 are correspondingly installed in the multiple mounting ports 5. Two mounting ports 5 are used as examples for illustration. Two conveying pipe seats and two burners 3 are used as examples for illustration. The gas pipe 6 on the burner 3 conveys gas to multiple gas channels 7, and the gas supply channel 8 of the burner 3 conveys hot air through multiple branch pipes 9, thereby forming multiple flame jets and making the gas fully combusted to reduce the emission of harmful gases (such as carbon monoxide). Compared with the traditional crucible 2 furnace, the furnace chamber 4 structure of this crucible 2 furnace increases the heating area of ​​the crucible 2 and improves the heating effect and service life of the crucible 2.

[0019] Specifically, a furnace base 10 is provided on the bottom surface of the furnace chamber 4, and the crucible 2 is fixed on the furnace base 10 of the furnace chamber 4. A conveying pipe 11 is provided inside the conveying pipe base, and a connecting seat 12 is provided between the conveying pipe base and the mounting port 5 in the furnace body 1. A connecting pipe 13 is provided inside the connecting seat 12, which is connected to the conveying pipe 11 and the gas supply channel 8 of the burner 3 respectively. Further, a distribution box 14 connected to multiple gas supply channels 7 is provided on the rear side of the burner 3, and the gas pipe 6 is connected to the distribution box 14. Even further, multiple branch pipes 9 of the two gas supply channels 8 of the burner 3 are inclined inwards, such as... Figures 1 to 5As shown, the conveying pipe 11 of the conveying pipe seat can be connected to an external gas supply pipe. Hot air is conveyed along the conveying pipe 11 to the connecting pipe 13 of the connecting seat 12. Then, the hot air is diverted along the conveying pipe 11 to the gas supply channel 8, and finally discharged from the branch pipe 9 to the furnace 4. The gas pipe 6 inputs gas into the distribution box 14, and the gas is discharged from the gas channel 7 to the furnace 4. The branch pipe 9 is inclined towards the gas channel 7 to facilitate the mixing of hot air and gas. It should be noted that the burner 3 can be equipped with an ignition needle (not shown in the figure). The ignition needle can extend into the furnace 4 from the distribution box 14 and one gas channel 7 to ignite the mixed gas and hot air. The other gas channel 7 can be equipped with a UV probe for sensing the flame (not shown in the figure). The gas and hot air are fully combusted and form multiple flame jets, which increases the heating area of ​​the crucible 2 and avoids heating the crucible 2 in a single position, thereby improving the heating effect and service life of the crucible 2.

[0020] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
