A first fan 8 is fixedly installed above the vertical barrel 2, a filter assembly 9 is provided on the inner side of the vertical barrel 2 above the first fan 8, a cover 10 is fixedly connected to the top of the trapezoidal bucket 3 corresponding to the top of the vertical barrel 2, and first curtains 11 are symmetrically fixedly connected on both sides of the cover 10. The first curtains 11 are arranged on both sides of the cover 10 to form a shield, and facilitate the entry and exit of the molten steel purification agent block, and a second fan 15 is fixedly embedded on the top of the cover 10, and the power of the second fan 15 is less than that of the first fan 8.

[0024] Through the cooperation of the second fan 15 and the first fan 8, a through-ventilation effect is formed, so that the dust and impurities on the molten steel purifier on the support plate 5 are blown off through the leakage hole 6. The power of the second fan 15 is less than that of the first fan 8, resulting in a negative pressure above the support plate 5, which effectively avoids the spread of dust and splashing, and the first curtain 11 forms a shield on both sides of the support plate 5 to further avoid the spread of dust.

[0025] An electric push rod 12 is symmetrically fixedly connected to the inner side of the top of the trapezoidal bucket 3 , and the telescopic end of the electric push rod 12 is fixedly connected to the bottom surface of the supporting plate 5 .

[0026] The side wall of the support plate 5 is fixedly connected with a second curtain 13, which extends out of the trapezoidal bucket 3 along the L-shaped fastener 4 and is fixedly connected with a counterweight 14. Both sides of the second curtain 13 are inserted between the L-shaped fastener 4 and the trapezoidal bucket 3 to form a guide.

[0027] By setting the electric push rod 12, the support plate 5 can be moved out from under the cover 10, which is convenient for taking out the purifier of the cleaned and cooled molten steel. By setting the second curtain 13 and the counterweight block 14, the top opening of the trapezoidal bucket 3 is always shielded by the second curtain 13 to avoid the negative pressure above the support plate 5 caused by a large amount of air intake from the side when the first fan 8 is working.

[0029] One side of the placement seat 16 extends out of the vertical barrel 2 and is fixedly connected with a sealing plate 18. The vertical barrel 2 is provided with an opening connected and adapted to the slide groove 17 at the position where the placement seat 16 passes through. The sealing plate 18 is fixedly installed with the vertical barrel 2 by bolts.

When the placement seat 16 is inserted into the slide slot 17, the filter frame 19 is fixed, so that the filter frame 19 can be easily taken out, cleaned, replaced, or installed during use, which is convenient for maintenance of the device.

[0032] The first fan 8, the electric push rod 12 and the second fan 15 are all externally connected to a power source and a switch.

[0033] The working principle of the utility model is:

[0034] When in use, the hot pressing machine pushes the formed molten steel purifier along the workbench 1 onto the support plate 5. At this time, the first curtain 11 forms a shield on both sides of the cover 10, and the first fan 8 and the second fan 15 are started. The external air enters the cover 10 through the second fan 15 and blows to the molten steel purifier to prevent the molten steel purifier from dust and residue falling. Under the action of the first fan 8, the impurities hanging above the support plate 5 are sucked into the vertical barrel 2 through the leakage hole 6. The impurities are filtered by the filter frame 19 on the filter assembly 9, and the impurities are retained in the filter frame 19. The air is discharged through the air outlet 7 to form through ventilation, and the molten steel purifier is ventilated and cooled simultaneously. The power of the first fan 8 is greater than that of the second fan 15, so that the two sides of the cover 10 are synchronously intake, which effectively prevents dust diffusion and residue splashing.

[0035] The electric push rod 12 drives the support plate 5 to slide along the L-shaped fastener 4, thereby pushing the support plate 5 out. During this process, the counterweight block 14 synchronously drives the second curtain 13 to fall to prevent the curtain from affecting the movement of the support plate 5. Finally, the molten steel purifier is pushed out from the bottom of the cover 10 for easy removal.

[0036] Release the bolts between the sealing plate 18 and the vertical barrel 2, and pull out the placement seat 16. At this time, the filter screen frame 19 can be taken out for cleaning or replacement, and the cleaned filter screen frame 19 is further placed in the step groove of the placement seat 16, and the placement seat 16 is pushed into the slide groove 17. At this time, the edge of the slide groove 17 and the step groove form an extrusion restriction on the filter screen frame 19, and the sealing plate 18 is further fixed to complete the enclosure of the device.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
