Description

Technical Field

[0001] The present invention relates to the technical field related to tungsten powder production, and specifically to a tungsten oxide reduction furnace for tungsten powder production with rapid gas replacement. Background Art

[0002] In the production process of tungsten powder, the reduction of tungsten oxide is a key link. Currently, the common reduction method in industrial production is to use a reduction furnace and hydrogen as a reducing agent for reduction. Therefore, in the process of tungsten powder production, a reduction furnace is required for preparation.

[0003] There are many types of existing tungsten oxide reduction furnaces, but there are still certain deficiencies in the process of use. After the reduction is completed, it is necessary to cool the metallic tungsten inside the reduction furnace. To solve the above defects, reference can be made to the hydrogen reduction furnace for processing ultrafine metallic tungsten powder disclosed in the prior art (application number: 200820051293.6, publication date: August 12, 2009, Chinese patent). This reduction furnace increases the length of the furnace tube and is provided with four temperature control zones on the furnace tube to effectively control the temperature inside the furnace tube, thereby processing ultrafine metallic tungsten powder. At the same time, reference can be made to the highly sealed reduction furnace for tungsten powder production disclosed in the prior art (application number: 202321075575.0, publication date: February 9, 2024, Chinese patent). This reduction furnace can adjust the temperature of the temperature control and condensation tube by installing two groups of front and rear condensation tubes, thereby being able to control the temperature inside the reduction furnace box, preventing the temperature from being too high and affecting the reaction of raw materials in the reaction pipeline, and effectively improving the safety performance of the reduction furnace. And reference can be made to the steam device for a multi-tube reduction furnace for medium and super-coarse particle tungsten powder disclosed in the prior art (application number: 201621473461.1, publication date: July 28, 2017, Chinese patent). The outer parts of the furnace barrel high-temperature return water main pipe, the chassis high-temperature return water main pipe, the tail gas cooler return water main pipe, the high-temperature steam inlet main pipe, the tail gas discharge pipe, the hot steam inlet branch pipe, the hot steam supplement branch pipe, and the water outlet pipe are all wrapped with antifreeze sleeves made of heat-insulating cotton material, which not only prevents the water pipes from freezing in cold winter weather and causing inconvenience in use, but also reduces the heat loss during the conduction process, further reducing the energy consumption. The entire steam system realizes the recycling of steam and the environmental protection treatment of tail gas, while ensuring the reaction temperature inside the multi-tube reduction furnace and having low energy consumption.

[0004] Although the above devices can perform certain cooling treatments, there are still some deficiencies in use. After tungsten powder undergoes a reduction reaction with hydrogen at high temperature, metallic tungsten and water are produced. Some of the metallic tungsten may adhere to the inner wall of the furnace body. When discharging materials later, the metallic tungsten cannot be discharged well and is prone to residual phenomena.

[0005] Therefore, we propose a tungsten oxide reduction furnace for tungsten powder production with rapid gas replacement to facilitate the solution of the problems mentioned above. Summary of the Invention

A feed inlet 4 is provided at the top of the reaction furnace body 3, and a discharge outlet 5 extends out of the bottom outside of the heat insulation box 1 at the bottom of the reaction furnace body 3; an oil conveying member 7 is fixed on the outer surface of the heat insulation box 1, and the output end and the recovery end of the oil conveying member 7 are communicated with both ends of an oil pipeline 8, and the middle outer side of the oil pipeline 8 is wound around the outer surface of the reaction furnace body 3; a set of air extraction pipes 6 are communicated at the top of the reaction furnace body 3, and the gas inside the reaction furnace body 3 can be quickly replaced by connecting with a pump body through the air extraction pipes 6. And a pipeline for inputting hydrogen is communicated at one side of the top of the reaction furnace body 3 close to the air extraction pipes 6. Heating wires are arranged inside the reaction furnace body 3, and a drain pipe is also arranged at the bottom of the discharge outlet 5.

[0035] First, when reduction treatment is required, through the setting of the control panel 2, the feed inlet 4 at the top of the reaction furnace body 3 is opened, and the discharge outlet 5 is closed. Subsequently, tungsten oxide can be put into the inside of the reaction furnace body 3. When it is filled to a certain amount, at this time, the gas inside the reaction furnace body 3 is discharged through the air extraction pipes 6 and the pump body. After the discharge, at this time, hydrogen is injected into the inside of the reaction furnace body 3 through the pipeline, so as to achieve the purpose of rapid replacement. In addition, when the heating wires inside the reaction furnace body 3 are started, at this time, the tungsten oxide inside the reaction furnace body 3 can be reduced, and metallic tungsten and water are generated under high temperature, and the water can be discharged through the drain pipe arranged at the discharge outlet 5 at the bottom of the reaction furnace body 3.

[0036] Embodiment 2

[0037] For rapid cooling treatment of the reaction furnace body 3, reference can be made to Appendix Figure 1 - Appendix Figure 7 and Appendix Figure 10, a driving motor 9 is fixedly installed on the outer side of the bottom of the heat insulation box 1. The output end of the driving motor 9 extends into the interior of the heat insulation box 1 and is fixed to the center position of the eccentric wheel 10. The outer side of the eccentric wheel 10 is attached to the outer side of the extrusion mechanism. The driving of the extrusion mechanism can narrow the channel of the oil delivery pipe 8. The setting of the extrusion mechanism also enables the operation of the knocking mechanism. One side of the knocking mechanism acts on the outer side of the bottom of the reaction furnace body 3; the extrusion mechanism includes a connecting plate 11 arranged on one side of the eccentric wheel 10, and moving rods 12 are fixed at the positions of the corners on one side of the connecting plate 11. The outer sides of the moving rods 12 penetrate and slide through the interior of the heat insulation box 1, and an extrusion block 14 is fixed at the end of the moving rod 12 that slides out of the outer side of the heat insulation box 1. A return spring 13 is fixed on the outer side of one end of the moving rod 12 close to the connecting plate 11, and the other end of the return spring 13 is fixed on the inner side of the heat insulation box 1; the inner side of the extrusion block 14 is attached to the outer side of the oil delivery pipe 8. The extrusion block 14 and the oil delivery pipe 8 form an extrusion structure through the moving rod 12, and the moving rod 12 and the interior of the heat insulation box 1 form an elastic sliding structure through the return spring 13; one side of the knocking mechanism can also drive the rotation mechanism to operate. The driving fan blade 28 fixed on the top of the rotation mechanism rotates inside the heat insulation box 1 to achieve rapid multi-directional cooling treatment; the rotation mechanism includes a bevel gear assembly 24. One set of gears of the bevel gear assembly 24 is fixed at the end of the mating gear 17, and the other set of gears of the bevel gear assembly 24 is fixed on the outer side of the bottom of the sector-shaped rotating rod 25. The upper outer side of the sector-shaped rotating rod 25 is rotatably arranged on the top of the fixing plate 23. Two connecting gears 26 are meshed and connected to the outer side of the upper end of the fixing plate 23. The bottom of the connecting gear 26 is connected to the outer side of the top of the fixing plate 23 through a torsion spring 27. The top of the connecting gear 26 is fixed on the outer side of the driving fan blade 28; the connecting gear 26 forms a rotating structure with the interior of the fixing plate 23 through the torsion spring 27, and the rotation range of the driving fan blade 28 is from 0 to 45 degrees.

[0038] When it is necessary to quickly cool down the reaction furnace body 3 and the internal tungsten metal, by starting the oil delivery part 7, the output end of the oil delivery part 7 injects cold oil into the interior of the oil delivery pipe 8, which can absorb the temperature of the reaction furnace body 3. And by starting the driving fan blade 28 arranged inside the heat insulation box 1, the outside of the internal reaction furnace body 3 can be quickly transferred through the driving fan blade 28. In addition, in order to accelerate the delivery efficiency of the oil delivery pipe 8, the cold oil inside the oil delivery pipe 8 can be quickly delivered through the setting of the extrusion mechanism. By starting the driving motor 9 installed outside the bottom of the heat insulation box 1, the output end of the driving motor 9 can drive the eccentric wheel 10 to rotate inside the heat insulation box 1, so that the connecting plate 11 attached to the outside of the eccentric wheel 10 can drive the moving rod 12 and the extrusion block 14 to move. At this time, the limit on the bottom position of the oil delivery pipe 8 can be released. And when the eccentric wheel 10 no longer presses on one side of the connecting plate 11, at this time, the connecting plate 11 will be reset through the return spring 13, and at this time, the extrusion block 14 will be reset through the elastic force of the return spring 13, so as to achieve the extrusion of the oil delivery pipe 8. When the oil delivery part 7 delivers at the same power, the flow rate will be accelerated, thereby improving the cooling efficiency. When rotating in cooperation with the mating gear 17, the end of the mating gear 17 rotates into the interior of the fixed plate 23. At this time, during the rotation of the mating gear 17, the mating gear 17 will drive the sector-shaped rotating rod 25 to rotate inside the fixed plate 23 through the bevel gear assembly 24, so that the sector-shaped rotating rod 25 can drive the meshing-connected connecting gear 26 to rotate, so that the connecting gear 26 drives the driving fan blade 28 to rotate in multiple positions. And when the sector-shaped rotating rod 25 and the connecting gear 26 are no longer meshed, the driving fan blade 28 can be reset to rotate, which can further cool the interior of the heat insulation box 1.

[0039] Embodiment III

[0040] In order to solve the problem that after tungsten powder on the current market undergoes a reduction reaction through hydrogen at high temperature, metallic tungsten and water will be produced, and some of the metallic tungsten may adhere to the inner wall of the furnace body. When discharging materials later, the metallic tungsten cannot be discharged well and is prone to residue problems, reference can be made to the attached Figure 1 - attached Figure 6 、attached Figure 8 and attached Figure 9, the knocking mechanism includes a screw rod 15 fixed to the side of the connecting plate 11 away from the moving rod 12. The outer side of the screw rod 15 is helically connected to the inner side of the rotating gear 16. The shaft end of the rotating gear 16 is rotatably arranged on one side surface of the fixed plate 23. The outer side of the fixed plate 23 is fixed inside the heat insulation box 1. The outer side of the rotating gear 16 is meshed and connected to the outer side of the mating gear 17. And a rotating groove 18 is provided at one end of the mating gear 17. A connecting block 19 is fitted inside the rotating groove 18. One end of the connecting block 19 is fixed to one side of the knocking block 20. Guide rods 21 are also fixed to the upper and lower ends of the knocking block 20. The outer sides of the guide rods 21 are slidably arranged inside the receiving rods 22; the end of the mating gear 17 is rotatably arranged on one side of the fixed plate 23. One side of the receiving rod 22 is fixed to one side of the fixed plate 23; a spring is also fixed inside the receiving rod 22. The other end of the spring is fixed to one side of the guide rod 21. The outer side of the knocking block 20 is in contact with the outer wall of the reaction furnace body 3. The knocking block 20 forms a sliding structure between the connecting block 19 and the inside of the guide rod 21. The outer side of the guide rod 21 is in contact with the inner side of the receiving rod 22. One end of the receiving rod 22 extends outside the heat insulation box 1. And a one-way air outlet valve is provided at the end of the receiving rod 22 extending outside the heat insulation box 1. A one-way air inlet valve is provided at the end of the receiving rod 22 arranged inside the heat insulation box 1; the shape of the connecting block 19 is arc-shaped. And the outer side of the connecting block 19 is in contact with the inner side of the rotating groove 18. The connecting block 19 forms a shaking structure with the outer wall of the reaction furnace body 3 through the rotation of the rotating groove 18.

[0041] When processing the residual tungsten metal inside the reaction furnace body 3, when the connecting plate 11 moves, the screw rod 15 fixed to one side of the connecting plate 11 will also move. At this time, the rotating gear 16 helically connected to the outer side of the screw rod 15 rotates on the outer side of the fixed plate 23, so that the mating gear 17 meshed and connected to the outer side of the rotating gear 16 also rotates on the outer side of the fixed plate 23. At this time, the rotating groove 18 provided at one end of the mating gear 17 moves, so that the connecting block 19 fitted during the rotation of the rotating groove 18 will move along with the rotating groove 18, so that the connecting block 19 drives the knocking block 20 to knock on the outer side of the reaction furnace body 3, facilitating the later material discharging process. At this time, during the movement of the knocking block 20, the knocking block 20 stably slides through the cooperation of the guide rod 21 and the receiving rod 22. Since the mutually close ends of the guide rod 21 and the receiving rod 22 are connected by a spring, it is convenient for the connecting block 19 to reset. In addition, since the outer side of the guide rod 21 and the inner side of the receiving rod 22 are in contact with each other, when the guide rod 21 moves, the guide rod 21 will convey the gas inside the receiving rod 22 to the outside of the heat insulation box 1. In addition, through the setting of the one-way air inlet valve, the gas can be conveyed into the inside of the guide rod 21. Through the above settings, heat dissipation treatment can be continuously carried out.
