SUMMARY
[0003] The utility model solves the technical problem to provide a kind of aluminium ash screening machine with good dustproof effect, it can effectively prevent aluminium ash from spreading to air to effectively reduce dust raising.
[0004] To solve the above technical problems, the aluminium ash screening machine with good dustproof effect of the utility model comprises a machine body, the machine body is provided with a discharging pipe with a pipe opening downward, and a receiving box for receiving aluminium ash is arranged below the discharging pipe, the box opening of the receiving box is upwardly aligned with the pipe opening of the discharging pipe, a dust bag is arranged between the discharging pipe and the receiving box, and the upper and lower ends of the dust bag are both provided with openings, the upper end opening is sleeved outside the discharging pipe, and the lower end opening is sleeved outside the receiving box.
[0005] Further, the dust bag is provided with a transparent observation window for observing the accumulation state of aluminium ash in the box.
[0006] Further, the transparent observation window is specifically a flexible PVC observation window.
[0007] Further, the box opening of the receiving box is larger than the pipe opening of the discharging pipe of the machine body.
[0008] Further, the dust bag is in inverted funnel shape with narrow upper end and wide lower end, and the lower end opening is larger than the upper end opening.
[0009] Further, the lower end of the dust bag extends downward to below the box opening of the receiving box and is close to the side wall of the receiving box under the action of gravity.
[0010] Further, the lower end opening of the dust bag is larger than the box opening of the receiving box.
[0011] Further, the lower end of the dust bag is in double-layer bag body structure.

[0022] The present invention will be further described in detail below with reference to specific embodiments.
[0023] Aluminum ash screening machine with good dustproof effect can be found Figure 1 and Figure 2 The system includes the existing aluminum ash screening machine body 1. Body 1 has three downward-facing feeding pipes 11 (left, center, and right). Below each feeding pipe 11 are three upward-facing receiving boxes 2 (left, center, and right), with their openings 20 aligned with the openings 110 of the feeding pipes 11. A feed inlet 12 is located on the upper side of body 1. During operation, aluminum ash enters body 1 through feed inlet 12. Body 1 screens the aluminum ash, and the screened ash is discharged from the three feeding pipes 11 and then into the three receiving boxes 2 for collection.
[0024] See Figure 1Three dust bags 3 are respectively installed between the three feeding pipes 11 and the three receiving boxes 2, on the left, in the middle and on the right. The three feeding pipes 11 have the same structure, the three receiving boxes 2 have the same structure, and the three dust bags 3 have the same structure. The following text takes the feeding pipe 11 in the middle, the receiving box 2 in the middle and the dust bag 3 in the middle as an example.
[0025] See Figure 2 and Figure 3 The opening 20 of the receiving box 2 is larger than the opening 110 of the feeding pipe 11. An annular groove 111 is formed on the outer wall of the middle section of the feeding pipe 11. Dust bag 3 is as follows... Figure 5 The dust bag 3 is an inverted funnel shape, narrower at the top and wider at the bottom. Both its upper and lower ends 31 and 32 have openings 311 and 321, respectively, with the lower opening 321 being larger than the upper opening 311. This aluminum ash screening machine is equipped with a strap 4. The upper opening 311 of the dust bag 3 is fitted over the outside of the feed pipe 11 of the machine body 1, secured by the strap 4. The strap 4 is embedded in the annular groove 111 and supported by the lower groove wall 112, preventing it from sliding downwards under gravity. The main body 30 of the dust bag 3 has a single-layer bag structure, with its lower opening 321 larger than the opening 20 of the receiving box 2, fitting over the outside of the receiving box 2. Figure 2 and Figure 4 The lower end 32 of the dust bag 3 has a double-layer bag structure, extending downwards to below the opening 20 of the receiving box 2. Under the action of gravity, it adheres closely to the side wall 25 of the receiving box 2, achieving a certain degree of sealing effect, preventing aluminum ash inside the box from being carried away by external airflow. Because the aluminum ash screening machine of this utility model has a dust bag 3 between the feeding pipe 11 and the receiving box 2, the dust bag 3 acts as a physical barrier. Even if aluminum ash is carried away by the airflow inside the box during the feeding process, the dust bag 3 can effectively block the aluminum ash, preventing it from spreading into the outside air, thus effectively reducing dust. Therefore, this aluminum ash screening machine has a good dust prevention effect.
[0026] See Figure 1 The dust bag 3 has a transparent flexible PVC observation window 35 on its front wall. Operators can observe the aluminum ash accumulation in the receiving box 2 through the observation window 35. When the box is found to be full of aluminum ash, the receiving box 2 should be replaced promptly to prevent aluminum ash overflow. Because the dust bag 3 is an inverted funnel shape, narrow at the top and wide at the bottom, its lower end 32 can fit over receiving boxes 2 of different sizes, such as... Figure 6 As shown, it has wide applicability.
[0027] See Figure 1 In this embodiment, the observation window 35 is a flexible PVC observation window, which has good flexibility and can adapt to the deformation of the dust bag 3 during use. In a non-preferred embodiment: a rigid PVC observation window 35 can be used instead, but the rigid PVC observation window 35 lacks flexibility and is difficult to adapt to the deformation of the dust bag 3 during use; or the observation window 35 can be omitted, but in this case, it would be difficult for the operator to judge the state of aluminum ash accumulation inside the receiving box 2.
[0028] Other embodiments are described below. Figure 7 The lower end 32 of the dust bag 3 has a single-layer bag structure with weight-increasing blocks 36 (such as lead blocks) sewn along its edges to ensure that the lower end 32 of the dust bag 3 adheres closely to the side wall 25 of the receiving box 2 under the influence of gravity. In a non-preferred embodiment, the lower end 32 of the dust bag 3 has a single-layer bag structure without weight-increasing blocks 36 sewn along its edges. Since the single-layer bag structure is lighter, the lower end 32 of the dust bag 3 may not adhere closely enough to the side wall 25 of the receiving box 2 under the influence of gravity.
[0029] See Figure 3 In a non-preferred embodiment, the annular groove 111 can be omitted. However, the strap 4 may slide downward along the outer wall of the feed tube 11 under the gravity of the dust bag 3, affecting the fixing effect of the dust bag 3.
[0030] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
