[0004] In the existing technology, the cam is used to push the screen plate to move back and forth to promote screening, and larger particles are discharged by rolling from the top surface of the screen plate. Although the reciprocating motion of the screen plate can promote the discharge of materials, some impurities slightly larger than the screen holes will be stuck in the screen holes, causing impurities to accumulate on the screen plate and thus affecting the screening efficiency.

[0005] To this end, we propose fly ash recovery and processing equipment. Utility Model Content

[0016] The utility model provides fly ash recovery and processing equipment, which has the following beneficial effects:

[0017] 1. The fly ash recovery and processing equipment feeds fly ash into the chamber of the processing box body through a hopper, and screens the falling fly ash through an inclined and extended sieve plate. Larger particle impurities are discharged from the window on the side wall of the processing box body through the receiving hopper, and smaller particles of fly ash fall and are discharged from the chute at the bottom of the processing box body, thereby realizing the screening and recovery of fly ash. The vibration motor is combined with the elastic telescopic rod to make the sieve plate generate a certain vibration in the vertical direction, thereby improving the screening effect and efficiency. At the same time, it can also promote the discharge of impurities to one side of the sieve plate.

[0018] 2. The fly ash recovery and processing equipment limits the highest point of the upward movement of the sieve plate by the vibration impact of the guide rod in the vertical direction of the sieve plate. At the same time, when the sieve plate hits the guide rod, it can suppress the accumulation of impurities and cause clogging of the sieve plate holes, thereby ensuring the screening effect. By pushing the limit rod upward, the convex rib of the limit rod slides in the side groove of the limit cylinder, and the nut is rotated. The nut contacts the bottom surface of the connecting plate, so that the guide rod cannot continue to move upward, and the upward position of the sieve plate is fixed. However, when the sieve plate moves downward, the guide rod can fall with the sieve plate, and the impurities on the sieve plate are guided by the guide rod, so that the impurities can better flow toward the drop chute, thereby promoting discharge.

[0024] Fly ash recovery and processing equipment, such as Figure 1 As shown, including:

[0025] The processing box body 10 has a hollow box structure, the bottom of the processing box body 10 is fixedly mounted with support legs, and the top of the processing box body 10 is fixedly mounted with a hopper for feeding materials;

[0026] like Figure 2 and Figure 3 As shown, the screening structure is arranged in the cavity of the processing box body 10 for screening. The screening structure includes a sieve plate 11, an elastic telescopic rod 12 and a vibration motor 13. Two elastic telescopic rods 12 are symmetrically arranged at the bottom of the sieve plate 11. The elastic telescopic rod 12 is fixedly connected to the bottom of the processing box body 10. The output shaft of the elastic telescopic rod 12 is fixedly connected to the bottom surface of the sieve plate 11. The vibration motor 13 is fixedly installed on the bottom surface of the sieve plate 11. The sieve plate 11 is installed tilted toward one side of the processing box body 10. A window for discharging is opened on the side wall of the processing box body 10. A material receiving hopper is provided in the window. The material receiving hopper is fixedly connected to the processing box body 10. A material chute for discharging is provided at the bottom of the processing box body 10.

[0027] Fly ash is fed into the chamber of the processing box body 10 through a hopper, and the falling fly ash is screened by the inclined extended sieve plate 11. Larger granular impurities are discharged from the window on the side wall of the processing box body 10 through the receiving hopper, and smaller particles of fly ash fall and are discharged from the chute at the bottom of the processing box body 10, thereby realizing the screening and recovery of fly ash. The vibration motor 13 is combined with the elastic telescopic rod 12 to make the sieve plate 11 generate a certain vibration in the vertical direction, thereby improving the screening effect and efficiency. At the same time, it can also promote the discharge of impurities to one side of the sieve plate 11.

[0028] like Figure 3 and Figure 4 As shown, the cleaning assembly is arranged in the cavity of the processing box body 10 for knocking the sieve plate 11 to clean the sieve holes. The cleaning assembly includes a guide rod 20, a connecting plate 21 and a limit rod 22. The connecting plate 21 is fixedly connected to the processing box body 10, and the limit rod 22 is movably connected to the connecting plate 21. The guide rod 20 is fixedly connected to the limit rod 22. The guide rod 20 can resist the top surface of the sieve plate 11 and hit the sieve plate 11. The guide rod 20 forms a rectangular rod structure. The guide rod 20 and the top surface of the sieve plate 11 The guide rod 20 is parallel to each other, the length of the guide rod 20 is less than the length of the screen plate 11, and the cleaning assembly also includes a nut 23 and a limit cylinder 24. The limit cylinder 24 is fixedly connected to the connecting plate 21, and the limit rod 22 is slidably connected to the limit cylinder 24. The nut 23 is threadedly connected to the limit rod 22. The limit cylinder 24 is fixedly installed on the top surface of the connecting plate 21. The end surface of the limit cylinder 24 is provided with a vertically extending side groove. The side wall of the limit rod 22 is provided with an integrally formed rib, which is slidably connected to the side groove. 24 passes through the connecting plate 21 and extends to the bottom of the connecting plate 21. The limiting rod 22 is provided with a thread adapted to the nut 23. The nut 23 is located below the connecting plate 21 and contacts the bottom surface of the connecting plate 21. By setting the guide rod 20, the vibration of the sieve plate 11 in the vertical direction hits the guide rod 20, so that the highest point of the sieve plate 11 is limited. At the same time, when the sieve plate 11 hits the guide rod 20, it can inhibit the accumulation of impurities and cause the sieve holes of the sieve plate 11 to be blocked, thereby ensuring the screening efficiency. As a result, by pushing the limit rod 22 upward, the rib of the limit rod 22 slides in the side groove of the limit cylinder 24, and the nut 23 is turned, the nut 23 contacts the bottom surface of the connecting plate 21, so that the guide rod 20 cannot continue to move upward, and the upward position of the sieve plate 11 is fixed. However, when the sieve plate 11 moves downward, the guide rod 20 can fall with the sieve plate 11, and the impurities on the sieve plate 11 are guided by the guide rod 20, so that the impurities can better flow toward the drop chute, thereby promoting discharge.

[0029] The working principle of the present invention is as follows: the hopper puts fly ash into the chamber of the processing box body 10, and the falling fly ash is screened by the inclined extended sieve plate 11, and the larger particle impurities are discharged from the window on the side wall of the processing box body 10 through the receiving hopper, and the smaller particle fly ash falls and is discharged from the drop chute at the bottom of the processing box body 10, realizing the screening and recovery of fly ash. The vibration motor 13 cooperates with the elastic telescopic rod 12 to make the sieve plate 11 vibrate to a certain extent in the vertical direction, thereby improving the screening effect and efficiency. At the same time, it can also promote the impurities to be discharged to one side of the sieve plate 11, pushing the limit rod 22 to move upward, and the convex rib of the limit rod 22 slides in the side groove of the limit cylinder 24, and rotating the nut 23. The nut 23 hits the bottom surface of the connecting plate 21, so that the guide rod 20 cannot continue to move upward, and the upward position of the sieve plate 11 is fixed. However, when the sieve plate 11 moves downward, the guide rod 20 can fall with the sieve plate 11, and the impurities on the sieve plate 11 are guided by the guide rod 20.
