Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to a high-efficiency powder metallurgy sintering furnace. Background Technology

[0002] Powder metallurgy is an industrial technology that produces metal powders or uses metal powders (or mixtures of metal powders and non-metal powders) as raw materials, and then shapes or sintersects them to produce metal materials, composite materials and various types of products.

[0003] Powder metallurgy generally requires the use of sintering furnaces for metallurgical operations. Sintering furnaces are specialized equipment used to obtain the required physical and mechanical properties and microstructures by sintering powder compacts. Existing high-efficiency powder metallurgy sintering furnaces generate waste gas during use. This waste gas, when directly emitted into the air, will pollute the surrounding environment. Furthermore, existing sintering furnaces typically use heating rods located at the top of the furnace body for heating and sintering. During sintering, there is a certain difference in sintering temperature between the metallurgical products located on the upper layer of the furnace body and those located on the lower layer, resulting in differences in the sintering quality of the metallurgical products on the upper and lower layers. Utility Model Content

[0030] In this embodiment: gas flows into the furnace body 1 through the inlet pipe 3, and exhaust gas is discharged to the outside of the furnace body 1 through the outlet pipe 4.

[0031] Please refer to this carefully. Figure 3 The purification unit 5 includes a treatment box 501, a connecting pipe 502, an exhaust pipe 503, a UV purification plate 504, an activated carbon plate 505, and a bamboo charcoal fiber plate 506.

[0032] The processing box 501 is fixedly connected to the outside of the furnace body 1. The input end of the connecting pipe 502 is connected to the output end of the gas outlet pipe 4, and the output end of the connecting pipe 502 is connected to the input end of the processing box 501. The UV purification plate 504, the activated carbon plate 505 and the bamboo charcoal fiber plate 506 are arranged in sequence from top to bottom inside the processing box 501. The exhaust pipe 503 is fixedly connected to the output end of the processing box 501.

[0033] In this embodiment: the exhaust gas flows through the exhaust pipe 4 to the inside of the connecting pipe 502, and the connecting pipe 502 then guides the exhaust gas into the treatment box 501. The exhaust gas flows inside the treatment box 501 and comes into full contact with the UV purification plate 504, the activated carbon plate 505, and the bamboo charcoal fiber plate 506. The UV purification plate 504 removes bacteria and viruses from the exhaust gas, the activated carbon plate 505 adsorbs harmful substances from the exhaust gas, and the bamboo charcoal fiber plate 506 purifies the exhaust gas. The filtered and purified exhaust gas is then discharged to the outside of the treatment box 501 through the exhaust pipe 503, thereby achieving the effect of purifying and filtering the exhaust gas.

[0034] Please refer to this carefully. Figure 3 The UV purification plate 504 is used to remove bacteria and viruses from the exhaust gas, the activated carbon plate 505 is used to adsorb harmful substances in the exhaust gas, and the bamboo charcoal fiber plate 506 is used to purify the exhaust gas.

[0035] In this embodiment: the exhaust gas circulates inside the treatment box 501, and the exhaust gas comes into full contact with the UV purification plate 504, the activated carbon plate 505 and the bamboo charcoal fiber plate 506, so that the UV purification plate 504 removes bacteria and viruses in the exhaust gas, the activated carbon plate 505 adsorbs harmful substances in the exhaust gas, and the bamboo charcoal fiber plate 506 purifies the exhaust gas.

[0036] Please refer to this carefully. Figure 4 The heat pipe assembly includes a heat-conducting outer ring 602, a heat-conducting inner ring 603, a heat-conducting pipe 605, and a spiral fin 606;

[0037] The outer heat-conducting ring 602 is fixedly connected to the inner wall of the furnace body 1, the inner heat-conducting ring 603 is rotatably connected to the inner wall of the outer heat-conducting ring 602, the heat-conducting pipe 605 is installed on the surface of the inner heat-conducting ring 603, and the spiral fins 606 are sleeved on the outer wall of the heat-conducting pipe 605.

[0038] In this embodiment: the heat generated by the heating rod 7 in operation is transferred to the surfaces of the two outer heat-conducting rings 602, and the two outer heat-conducting rings 602 then transfer this heat to the surfaces of the two inner heat-conducting rings 603, and the two inner heat-conducting rings 603 then transfer this heat to the surfaces of the multiple heat-conducting pipes 605. Since the spiral fins 606 are sleeved on the outer wall of the heat-conducting pipes 605, the spiral fins 606 dissipate the heat from the surface of the heat-conducting pipes 605 outward, achieving a diffusion effect.

[0039] Please refer to this carefully. Figure 4 The drive assembly includes a motor 601, a bracket 604, and a rotating shaft 607;

[0040] The motor 601 is fixedly installed on the outside of the furnace body 1, the bracket 604 is fixedly connected to the inner wall of the heat-conducting inner ring 603, one end of the rotating shaft 607 is fixedly connected to the output shaft end of the motor 601, and the other end of the rotating shaft 607 is fixedly connected to the bracket 604.

[0041] In this embodiment: by connecting the motor 601 to power, the output shaft of the running motor 601 drives the rotating shaft 607 to rotate. The rotating shaft 607 drives the inner heat-conducting ring 603 to rotate along the inner wall trajectory of the outer heat-conducting ring 602 through the bracket 604. The rotating inner heat-conducting ring 603 drives multiple heat-conducting pipes 605 and spiral fins 606 to rotate in a circle. Thus, the multiple heat-conducting pipes 605 and spiral fins 606 work together to uniformly heat the metallurgical product, which effectively improves the heat conduction efficiency of the device for the metallurgical product and makes the internal temperature of the furnace body 1 more uniform.

[0042] Please refer to this carefully. Figure 4 A heating rod 7 is fixedly installed inside the furnace body 1, and the heating rod 7 is connected to two heat-conducting outer rings 602.

[0043] In this embodiment: Since the heating rod 7 is connected to the two heat-conducting outer rings 602, the heat generated by the heating rod 7 in operation is transferred to the surface of the two heat-conducting outer rings 602.

[0044] Working principle: Since the heating rod 7 is connected to the two outer heat-conducting rings 602, the heat generated by the heating rod 7 during operation is transferred to the surfaces of the two outer heat-conducting rings 602. The two outer heat-conducting rings 602 then transfer this heat to the surfaces of the two inner heat-conducting rings 603, and the two inner heat-conducting rings 603 then transfer this heat to the surfaces of the multiple heat-conducting pipes 605. Since the spiral fins 606 are fitted on the outer wall of the heat-conducting pipes 605, the spiral fins 606 dissipate the heat from the surface of the heat-conducting pipes 605 outward, achieving a diffusion effect. At this time, the motor 601 is connected... When the motor is in operation, the output shaft of the motor 601 drives the rotating shaft 607 to rotate. The rotating shaft 607 drives the inner heat-conducting ring 603 to rotate along the inner wall trajectory of the outer heat-conducting ring 602 through the bracket 604. The rotating inner heat-conducting ring 603 drives multiple heat-conducting pipes 605 and spiral fins 606 to rotate in a circle. Thus, the multiple heat-conducting pipes 605 and spiral fins 606 work together to uniformly heat the metallurgical products, which effectively improves the heat conduction efficiency of the device for metallurgical products and makes the internal temperature of the furnace body 1 more uniform.

[0045] The exhaust gas flows through the outlet pipe 4 to the connecting pipe 502, which then guides the exhaust gas into the treatment box 501. The exhaust gas circulates within the treatment box 501, ensuring full contact with the UV purification plate 504, activated carbon plate 505, and bamboo charcoal fiber plate 506. The UV purification plate 504 removes bacteria and viruses from the exhaust gas, the activated carbon plate 505 adsorbs harmful substances, and the bamboo charcoal fiber plate 506 purifies the exhaust gas. The filtered and purified exhaust gas is then discharged through the exhaust pipe 503 to the outside of the treatment box 501, thus achieving the effect of purifying and filtering the exhaust gas.
