[0025] Example:

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A large casting and forging dust treatment device includes a main body 1. An end cover 2 is fitted onto the upper end of the main body 1. A pressure regulating valve is installed on the side wall of the main body 1 to control the internal pressure. An installation cover 3 is fixed on the upper side of the end cover 2. An exhaust fan 4 is fixed inside the installation cover 3. The exhaust fan 4 is made of high-temperature resistant material and is not easily damaged. An annular plate 5 is fixed on the outer wall of the main body 1. A support plate 6 is fixed on the right side of the annular plate 5. A filter box 7 is fixed on the upper side of the support plate 6. Support mechanisms are fixed on the front and rear sides of the filter box 7. A fixed cover 8 is installed on the upper end of the filter box 7 through symmetrical support mechanisms. A connecting hose 9 is fixed on the upper side of the installation cover 3. The other end of the connecting hose 9 extends into the interior of the fixed cover 8.

[0028] A first housing 10 is fixed to the left side of the filter box 7. Inside the first housing 10, a first winding roller 11 is symmetrically mounted. A filter screen 12 is wound around the outside of the first winding roller 11, extending between the filter box 7 and the fixed cover 8. A second housing 13 is fixed to the right side of the filter box 7. When the filtration effect of the filter screen 12 located in the upper part of the filter box decreases, a new section of filter screen 12 is moved directly to the upper end of the filter box 7 to continue filtering the smoke and dust. The filter box 13 is equipped with a second winding roller 14, which is rotated inside. The lower end of the second winding roller 14 is equipped with a transmission mechanism. The right end of the filter screen 12 is fixedly connected to the second winding roller 14. The lower side of the support plate 6 is fixed with an alkaline solution holding tank 15 by a mounting bracket. The lower side of the filter box 7 is fixed with a vertical pipe 16, the lower end of which extends into the interior of the alkaline solution holding tank 15. The lower right end of the alkaline solution holding tank 15 is fixed with a discharge pipe 17. The alkaline solution contained inside the alkaline solution holding tank 15 neutralizes and absorbs acidic substances in the gas.

[0029] An observation window 18 is provided on the front side of the main body 1 to facilitate observation of the production status of the internal castings and forgings.

[0030] Handles 19 are fixed to both the front and rear sides of the end cap 2.

[0031] The support mechanism includes two fixing blocks 20, which are fixedly connected to the front and rear sides of the filter box 7 respectively. A cylinder 21 is fixed on the upper side of each of the two fixing blocks 20, and an mounting block 22 is fixed on the upper end of each of the two cylinders 21. The side of each mounting block 22 that is close to each other is fixedly connected to the side wall of the fixing cover 8. The support mechanism can control the lifting and lowering of the upper fixing cover 2.

[0032] The mounting mechanism includes two mounting rods 23. The opposite ends of the two mounting rods 23 are rotatably connected to the inner wall of the first housing 10. The adjacent ends of the two mounting rods 23 are fixedly connected to both ends of the first winding roller 11 by bolts. When the filter screen 12 on the outside of the first winding roller 11 is used up, it is convenient to replace the first winding roller 11. When a large amount of filter screen 12 is wound on the outside of the second winding roller 14, it can be directly cut off.

[0033] The transmission mechanism includes a dual-axis motor 24, which is fixedly connected to the inner wall of the second housing 13.

[0035] Working principle:

[0036] During use, large castings and forgings are produced inside the main body 1. This process generates smoke and dust. The exhaust fan 4 is activated, and it discharges the smoke and dust through the connecting hose 9 into the fixed cover 8. The smoke and dust then pass through the filter screen 12 and enter the vertical pipe 16, finally reaching the alkali solution container 15 where it comes into contact with the alkali solution for dissolution. If the filter screen 12's filtration efficiency decreases after prolonged use, the fixed cover 8 can be moved upwards via the support mechanism. The dual-axis motor 24 is then activated, driving the transmission rods 25 at both ends to rotate. These transmission rods 25 drive the first pulley on the rod wall to rotate, which in turn drives the second pulley via a belt. The second pulley then drives the second winding roller 14 to rotate, winding the filter screen 12 while the first winding roller 11 rotates to unwind it. When a new section of filter screen 12 is moved to the top of the filter box 7, the fixed cover 8 is pulled by the support mechanism to fix the filter screen 12, continuing the filtration of smoke and dust.
