[0022] 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.

[0023] like Figures 1 to 5 As shown, a splash-proof protection device for a medium-frequency furnace includes a furnace body 1; an exhaust port 12 is provided on the side of the furnace body 1, a top cover 13 is provided on the top of the furnace body 1, a filter frame 14 is fixedly connected to the inner side of the furnace body 1, a first mounting plate 15 is slidably connected to the inner side of the top cover 13, a handle is fixedly connected to the top of the first mounting plate 15, a connecting rod 16 is fixedly connected to the bottom of the first mounting plate 15, a second mounting plate 17 is fixedly connected to the bottom of the connecting rod 16, the second mounting plate 17 is slidably connected to the filter frame 14, and the side of the exhaust port 12 is slidably connected to... There is a baffle 18; during operation, the first mounting plate 15 is pulled upward by the handle on the top of the first mounting plate 15, separating the first mounting plate 15 from the filter frame 14. The first mounting plate 15 drives the connecting rod 16 to move upward, and the connecting rod 16 drives the second mounting plate 17 to move upward, separating the second mounting plate 17 from the filter frame 14. At this time, the raw material can be poured into the furnace body 1 through the opening on the inside of the first mounting plate 15 and the filter frame 14. When the second mounting plate 17 is connected to the filter frame 14 and the first mounting plate 15 is connected to the top cover 13, the raw material is poured into the furnace body 1 through the opening on the inside of the filter frame 14. The filter frame 14 filters impurities in the rising hot air. The second mounting plate 17 protects the opening inside the filter frame 14, and the first mounting plate 15 protects the opening inside the furnace body 1. Pulling the first mounting plate 15 upward exposes the bottom through-hole, allowing hot air to escape through the filter frame 14 and the bottom through-hole of the first mounting plate 15. When the bottom surface of the first mounting plate 15 is in contact with the top cover 13, all the bottom through-holes are located inside the top cover 13. At this time, the hot air inside the furnace body 1 will not escape from the top. This step is achieved through the filter frame 14, the second mounting plate 17, and the first mounting plate 15. The first mounting plate 15 and the second mounting plate 17 are provided. The second mounting plate 17 can block the opening inside the filter frame 14 to prevent hot air from carrying impurities through the opening inside the filter frame 14 to the top of the filter frame 14. The filter frame 14 can reduce the impurities inside the hot air and filter and protect the hot air rising from inside the furnace body 1. The filter frame 14 has a conical structure. The through hole at the bottom of the first mounting plate 15 can exhaust the furnace body 1. The baffle 18 can block the exhaust port 12 to prevent hot air from spraying out of the exhaust port 12 and scalding the staff.

[0024] like Figure 3 and Figure 5As shown, a groove is provided on the inner side of the baffle 18, and a slider 21 is slidably connected to the inner side of the groove. A connecting plate 22 is fixedly connected to the inner side of the slider 21. An exhaust valve 23 is connected to the top of the connecting plate 22. A filter screen 24 is fixedly connected to the inner side of the slider 21, and a shielding layer 25 is fixedly connected to the bottom of the filter screen 24. During operation, the air inside the baffle 18 is discharged through the exhaust valve 23. When hot air enters the baffle 18, impurities in the hot air are filtered through the filter screen 24 and the shielding layer 25. Pulling the exhaust valve 23 allows... It drives the connecting plate 22 to move, and the connecting plate 22 drives the slider 21 to move, so that it separates from the inner groove, and the filter screen 24 can be disassembled. In this step, the hot air inside the baffle 18 can be discharged upward through the exhaust valve 23. When the exhaust speed at the top of the furnace body 1 is insufficient, the exhaust valve 23 can be opened to relieve the exhaust pressure at the top of the furnace body 1. The hot air can be filtered through the filter screen 24 and the shielding layer 25. When impurities come into contact with the shielding layer 25 and the filter screen 24, they will be filtered, reducing impurities in the hot air and preventing impurities from splashing everywhere.

[0025] like Figure 2 and Figure 4 As shown, a first sealing gasket 31 is fixedly connected to the side of the first mounting plate 15, and the first sealing gasket 31 is in contact with the top cover 13. A second sealing gasket 32 ​​is fixedly connected to the side of the second mounting plate 17, and the second sealing gasket 32 ​​is in contact with the filter frame 14. During operation, when the first mounting plate 15 is moved, the first sealing gasket 31 is moved, and when the second mounting plate 17 is moved, the second sealing gasket 32 ​​is moved. This step can seal the connection between the first mounting plate 15 and the top cover 13 through the first sealing gasket 31, and seal the connection between the second mounting plate 17 and the filter frame 14 through the second sealing gasket 32, and increase the stability of the first mounting plate 15 and the second mounting plate 17 during installation.

[0026] like Figure 4 As shown, a first limiting block 41 is fixedly connected to the side of the first sealing gasket 31, and a second limiting block 42 is fixedly connected to the top of the top cover 13. The first limiting block 41 and the second limiting block 42 are slidably connected. During operation, rotating the first sealing gasket 31 moves the first limiting block 41, causing it to insert into the second limiting block 42. When the first limiting block 41 is connected to the limiting groove at the bottom of the second limiting block 42, all the through holes of the first mounting plate 15 are located at the bottom of the top cover 13. When the first limiting block 41 is connected to the upper limiting groove, all the through holes at the bottom of the first mounting plate 15 are moved out of the top cover 13. This step can drive the first limiting block 41 to connect with the second limiting block 42 by rotating the first mounting plate 15. The second limiting block 42 limits the first limiting block 41, increasing the stability of the first mounting plate 15 during installation.

[0027] like Figure 2 and Figure 4As shown, the top of the furnace body 1 is provided with a snap-fit ​​groove 51, and the bottom of the top cover 13 is fixedly connected with a sealing plate 52. The snap-fit ​​groove 51 and the sealing plate 52 are slidably connected. During operation, when the top cover 13 is connected to the furnace body 1, the top cover 13 drives the sealing plate 52 to insert into the inside of the snap-fit ​​groove 51. This step limits the top cover 13 through the snap-fit ​​groove 51 and the sealing plate 52, so that the top cover 13 can be fixed on the top of the furnace body 1.

[0028] like Figure 2 As shown, a collection trough 61 is fixedly connected to the inner side of the baffle 18, and the collection trough 61 is slidably connected to the exhaust port 12. During operation, when hot air passes through the filter screen 24 and the shielding layer 25, and impurities inside are filtered down, the collection trough 61 can catch the falling impurities. This step can collect the filtered impurities through the collection trough 61. The baffle 18 is slidably connected to the exhaust port 12 through the insertion rod and the insertion hole. When the baffle 18 is removed, the collection trough 61 can be taken out for cleaning.

[0029] Working principle: Pulling the handle on the top of the first mounting plate 15 rotates the first mounting plate 15, then pulls it upwards, separating it from the filter frame 14. The first mounting plate 15 then moves the connecting rod 16 upwards, which in turn moves the second mounting plate 17 upwards, separating it from the filter frame 14. At this point, raw materials can be poured into the furnace body 1 through the openings on the inner sides of the first mounting plate 15 and the filter frame 14. When the second mounting plate 17 is connected to the filter frame 14 and the first mounting plate 15 is connected to the top cover 13, the filter frame 14 filters impurities in the rising hot air. The second mounting plate 17 protects the openings on the inner side of the filter frame 14, and the first mounting plate 15 protects the openings on the inner side of the furnace body 1. Pulling the top cover 13 upwards pulls the first mounting plate 15 upwards, exposing the bottom opening. Hot air passes through the filter frame 14 and the first mounting plate 14... 5. The bottom through-holes discharge. When the bottom surface of the first mounting plate 15 is in contact with the top cover 13, all the bottom through-holes are located inside the top cover 13. At this time, the hot air inside the furnace body 1 will not be discharged from the top. When the first mounting plate 15 is moved, the first sealing gasket 31 is moved. When the second mounting plate 17 is moved, the second sealing gasket 32 ​​is moved. When the first sealing gasket 31 is rotated, the first limiting block 41 is moved, causing it to move out of the second limiting block 42. The air inside the baffle 18 is discharged through the exhaust valve 23. When the hot air enters the baffle 18, the impurities in the hot air are filtered through the filter screen 24 and the shielding layer 25. When the hot air passes through the filter screen 24 and the shielding layer 25, the internal impurities are filtered down. The collecting groove 61 can catch the falling impurities. Pull the exhaust valve 23, causing it to move the connecting plate 22. The connecting plate 22 causes the slider 21 to move, causing it to separate from the inner sliding groove. The filter screen 24 can be disassembled.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
