Description

Technical Field

[0001] This utility model relates to a tungsten-molybdenum metal smelting device, belonging to the field of metal smelting technology. Background Technology

[0002] Tungsten and molybdenum are two metals. Tungsten is a metal with excellent physical and chemical properties, including high temperature resistance, thermal conductivity, electrical conductivity, and wear resistance. Molybdenum is a hard metal with high hardness and wear resistance. Molybdenum belongs to the same element group in the periodic table and has the same properties as tungsten. Tungsten is mainly used in the steel industry to manufacture various wear-resistant parts, drills, cutting tools, and cutting tools. With the rapid development of the tungsten and molybdenum smelting industry, the demand for tungsten and molybdenum is also increasing.

[0003] During the processing of tungsten and molybdenum, they need to be calcined. During the calcination process, a large amount of soot is generated during the smelting of tungsten and molybdenum. The soot is discharged from the exhaust pipe of the tungsten and molybdenum smelting equipment. Over time, the soot accumulates and blocks the exhaust pipe, causing the ventilation speed of the tungsten and molybdenum smelting equipment to decrease. A large amount of soot cannot be discharged in time, which can easily lead to a large accumulation of soot inside the equipment, thereby increasing the equipment failure rate and maintenance costs. At the same time, avoiding soot accumulation may also cause safety hazards. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tungsten and molybdenum metal smelting device to solve the problem mentioned in the background art that during the smelting process of tungsten and molybdenum, the long-term use of the exhaust pipe causes soot to accumulate and block the exhaust pipe, making it difficult to discharge the soot gas during smelting in a timely manner.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a tungsten-molybdenum metal smelting device, including a smelting furnace, a smelting cover installed on the top of the smelting furnace, and an exhaust port opened on the top of the smelting cover;

[0006] The top of the smelting furnace is equipped with an anti-clogging exhaust mechanism. The exhaust mechanism includes an installation frame. A bidirectional screw is installed between the two ends of the installation frame. Displacement sliders are sleeved on both ends of the outer side of the bidirectional screw. A connecting rod is installed on one side of each of the two displacement sliders. An installation rod is installed on the top of each of the two displacement sliders.

[0007] Furthermore, a triangular bracket is installed on the upper side of one side of the smelting furnace, a filter box is installed on the top of the triangular bracket, an L-shaped auxiliary frame is provided on the lower side of one side of the filter box, a sealing cover is placed on one side of the filter box, and the bottom of the sealing cover is inserted into the cavity of the L-shaped auxiliary frame. A stabilizing mechanism for stabilizing the smelting furnace is provided on the outside of the smelting furnace. The stabilizing mechanism includes a C-shaped positioning frame. The two C-shaped positioning frames are located at both ends of the outside of the smelting furnace, and the two C-shaped positioning frames wrap around the outside of the smelting furnace.

[0008] Furthermore, an assembly frame is installed above both ends of one side of the sealing cover, and a guide rod is installed between the top and bottom of the two assembly frame cavities. Guide blocks are fitted below both ends of the outer sides of the two guide rods, and auxiliary springs are fitted above both ends of the outer sides of the two guide rods, with the two auxiliary springs located above the two guide blocks respectively.

[0009] Furthermore, one side of each of the two guide sliders is connected to the lower part of one end of the inner side of each of the two L mounting brackets, and one end of each of the two L mounting brackets is installed at both ends of one side of the fixing plate. The bottom of the fixing plate is provided with an array of fixing pins, and the top side of the filter box is provided with an array of fixing holes, and the fixing pins are inserted into the fixing holes one by one.

[0010] Furthermore, each of the two connecting rods is provided with a fixing clamp at one end, and each of the two mounting rods is provided with an auxiliary clamp at one end. One end of the left connecting pipe and one end of the right connecting pipe are respectively inserted between the two fixing clamps, and the other end of the left connecting pipe and the other end of the right connecting pipe are respectively inserted between the two auxiliary clamps. One side of the left connecting pipe is in contact with one side of the right connecting pipe, and one end of the left connecting pipe and one end of the right connecting pipe are connected to the exhaust port, and the other end of the left connecting pipe and the other end of the right connecting pipe are connected to the filter box.

[0011] Furthermore, each of the two C-shaped positioning frames has an auxiliary plate at one end, and one side of each of the two C-shaped positioning frames is connected to one end of the assembly frame. A double-ended screw is installed between the two ends inside the cavity of the assembly frame.

[0012] Furthermore, movable sliders are fitted at both ends of the outer sides of the two double-headed screws, one side of each movable slider is connected to one side of the auxiliary plate, and auxiliary support rods are respectively installed in an array on one side of each of the two C-shaped positioning frames.

[0013] The beneficial effects of this utility model are:

[0014] 1. By utilizing the exhaust mechanism, the exhaust pipe of the device can be prevented from becoming blocked during long-term use, which would prevent the subsequent soot from being discharged in a timely manner. The soot would accumulate inside the equipment, leading to an increased failure rate and higher maintenance costs. At the same time, avoiding soot accumulation could also cause safety hazards.

[0015] 2. The exhaust pipe of the exhaust mechanism is assembled in a modular way. Users can disassemble the exhaust pipe into a left connecting pipe and a right connecting pipe. The disassembled left and right connecting pipes make it easy for users to clean the soot on the inner wall and prevent the exhaust pipe from getting blocked.

[0016] 3. The filter plate inside the filter box of the exhaust mechanism filters the soot, preventing the soot from being directly emitted and polluting the environment, protecting the environment around the device, and thus protecting the health of the workers and preventing them from developing occupational diseases due to long-term exposure to soot.

[0017] 4. The stabilizing mechanism can improve the stability of the device during use, prevent unstable shaking during operation, and thus prevent safety accidents, thereby improving the safety of the device. At the same time, the device and the stabilizing mechanism are designed separately, which facilitates the subsequent disassembly and maintenance of the device. Attached Figure Description

[0028] Please see Figures 3-4 Assembly frames 14 are installed on the top of both ends of the sealing cover 13. Guide rods 15 are installed between the top and bottom of the cavity of the two assembly frames 14. Guide sliders 16 are sleeved on the bottom of the two outer ends of the two guide rods 15. Auxiliary springs 17 are sleeved on the top of the two outer ends of the two guide rods 15. The two auxiliary springs 17 are respectively located above the two guide sliders 16. One side of the two guide sliders 16 is connected to the bottom of one end of the inner side of the two L mounting brackets 18. One end of the two L mounting brackets 18 is respectively installed on both ends of one side of the fixing plate 19. Fixing pins 20 are arranged in an array at the bottom of the fixing plate 19. Fixing holes 21 are arranged in an array on one side of the top of the filter box 11. The fixing pins 20 are inserted into the fixing holes 21 one by one.

[0029] Please see Figures 3-5 Each of the two connecting rods 7 has a fixing clamp 22 at one end and an auxiliary clamp 23 at one end. The left connecting pipe 24 and the right connecting pipe 25 are respectively inserted between the two fixing clamps 22. The other end of the left connecting pipe 24 and the other end of the right connecting pipe 25 are respectively inserted between the two auxiliary clamps 23. One side of the left connecting pipe 24 is in contact with one side of the right connecting pipe 25. One end of the left connecting pipe 24 and one end of the right connecting pipe 25 are connected to the exhaust port 3. The other end of the left connecting pipe 24 and the other end of the right connecting pipe 25 are connected to the filter box 11.

[0030] See Figure 1 and Figure 6 A stabilizing mechanism for the smelting furnace 1 is provided on the outside of the smelting furnace 1. The stabilizing mechanism includes a C-shaped positioning frame 9. Two C-shaped positioning frames 9 are located at both ends of the outside of the smelting furnace 1, and the two C-shaped positioning frames 9 wrap around the outside of the smelting furnace 1. An auxiliary plate 26 is provided at one end of each of the two C-shaped positioning frames 9.

Auxiliary support rods 30 are installed in an array on one side of each of the two C-shaped positioning frames 9.

[0031] Detailed implementation: Tungsten and molybdenum metals are smelted in the smelting furnace 1. During the smelting process, a large amount of soot is generated. The soot is discharged from the exhaust port 3 and enters the pipe between the smelting furnace 1 and the filter box 11. The left connecting pipe 24 and the right connecting pipe 25 cooperate to form the pipe between the smelting furnace 1 and the filter box 11. During long-term use, a large amount of soot adheres to the inner wall of the left connecting pipe 24 and the right connecting pipe 25. The soot blocks the exhaust pipe. Rotating the bidirectional screw 5 causes the displacement slider 6 on the bidirectional screw 5 to move the connecting rod 7 and the mounting rod 8, thereby separating the two fixed clamps 22 and the two auxiliary clamps 23. The left connecting pipe 24 and the right connecting pipe 25 are separated and removed. The user can clean the inner wall of the removed left connecting pipe 24 and the right connecting pipe 25 to avoid pipe blockage. The soot enters the filter box 11 from the pipe formed by the left connecting pipe 24 and the right connecting pipe 25 and is filtered by the filter plate 31.

[0032] After the filter plate 31 has been used for a long time, move the fixing plate 19 upward so that the fixing pin 20 is disengaged from the fixing pin hole 21. Then move the sealing cover 13 upward so that the bottom of the sealing cover 13 is disengaged from the L auxiliary frame 12 to open the filter box 11. The user cleans the filter plate 31 inside the filter box 11. After cleaning, insert the bottom of the sealing cover 13 into the L auxiliary frame 12 and then use the fixing pin 20 to insert it into the fixing pin hole 21 to close the filter box 11. During maintenance and other operations, in order to avoid the stabilizing mechanism from obstructing the device, rotate the double-headed screw 28 so that the moving slider 29 carries the two C-shaped positioning frames 9 away from the smelting furnace 1, thereby separating the stabilizing mechanism from the smelting furnace 1.
