[0027] To make the purposes, technical solutions and advantages of the implementation manners of the present utility model clearer, the technical solutions in the implementation manners of the present utility model are described clearly and completely. Obviously, the described implementation manners are part of the implementation manners of the present utility model, rather than all of them. Based on the implementation manners in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0028] To solve the technical problems in the background art, the following discharging roller bucket elevator ash return device is provided:

[0029] Combined with Figures 1 - 5 As shown in the figure, the discharging roller bucket elevator ash return device provided by the present utility model includes an ash return box 1. A support plate 11 is provided at the top of the ash return box 1. An installation box 2 is provided on the top of the support plate 11. An air guiding mechanism 3 for driving air flow is provided inside the installation box 2. An ash extraction mechanism 4 for cleaning accumulated ash is provided on the side of the installation box 2. An ash return opening 111 is formed in the middle of the support plate 11. The ash return opening 111 can collect the accumulated ash cleaned and collected by the staff and guide the accumulated ash into the interior of the ash return box 1. An installation plate 21 is provided in the middle of the inner side of the installation box 2. Electric push rods 5 are provided at both ends of the installation plate 21. The bottom ends of the electric push rods 5 are fixedly connected to the support plate 11. A plurality of guide rods 6 are provided on the top surface of the support plate 11. The guide rods 6 are in sliding fit with the installation box 2 and are in clamping sliding fit with the installation plate 21. The guide rods 6 can improve the stability when the installation box 2 is lifted and lowered above the ash return box 1. The ash return box 1 is fixedly arranged on the side of the discharging roller bucket elevator 7. The installation box 2 is in sliding fit with the discharging roller bucket elevator 7;

[0030] As an improvement of the above solution, the installation box 2 and the ash return box 1 have two states: ash extraction and ash return. In the ash extraction state: the bottom of the installation box 2 is attached to the top surface of the pallet 11, and the ash return port 111 is at the middle of the bottom end of the installation box 2. The ash extraction mechanism 4 generates suction force. In this way, it is convenient for the staff to use the ash extraction mechanism 4 to clean the accumulated ash in the areas around the discharging roller hoist 7 that are not easy to clean. In the ash return state: the bottom of the installation box 2 is separated from the top surface of the pallet 11, and the ash return port 111 is exposed below the installation box 2. At this time, the staff can sweep the accumulated ash into the ash return port 111, so that the ash enters the ash return box 1.

[0031] In this implementation scheme, an ash outlet 12 is provided on the side of the bottom of the ash return box 1, and a dust guiding plate 13 is provided in the middle of the inner side of the ash return box 1. The top surface of the dust guiding plate 13 is in a V-shaped structure. The V-shaped dust guiding plate 13 is convenient for gathering air and the ash entering the ash return box 1, so that the air and the ash enter the ventilation channel. A ventilation channel is provided in the middle of the dust guiding plate 13.

[0032] Combined Figures 1 - 6 As shown in the figure, in order to improve the ash return effect of the ash return device, the following design is given in this implementation scheme:

[0033] In this implementation scheme, the air guiding mechanism 3 includes a motor 31, a rotating rod 32 and a vortex blade 33. The motor 31 is arranged at the top of the inner side of the installation box 2. A rotating rod 32 is provided at the output end of the motor 31. A vortex blade 33 is provided at the bottom end of the rotating rod 32. When the vortex blade 33 is driven by the motor 31 to rotate, it will blow downward, generating suction at the ash return port 111 at the top of the ash return box 1. In this way, when the device is in the ash extraction state, the suction force will be transmitted to the ash extraction mechanism 4. When the device is in the ash return state, the ash return port 111 generates suction force, which can assist the staff to sweep the accumulated ash into the ash return box 1 through the ash return port 111. The vortex blade 33 is located in the middle of the inner side of the ventilation channel. A support 14 is provided above the ventilation channel. The support 14 is fixedly connected to the ash return box 1. The rotating rod 32 is engaged and slid with the support 14. The support 14 can improve the stability of the rotating rod 32 and the vortex blade 33 when rotating.

[0034] In this implementation scheme, the ash extraction mechanism 4 includes a connecting cylinder 41, an ash extraction pipe 42 and an ash extraction nozzle 43. The connecting cylinder 41 is arranged on the side of the installation box 2. The connecting cylinder 41 is engaged and rotatable with the installation box 2. An ash extraction pipe 42 is provided on the outer side of the connecting cylinder 41. One end of the ash extraction pipe 42 communicates with the connecting cylinder 41. An ash extraction nozzle 43 is provided at the end of the ash extraction pipe 42 away from the connecting cylinder 41. By providing the ash extraction pipe 42 and the ash extraction nozzle 43, when the device is in the ash extraction state, the ash extraction nozzle 43 can be used to extract and clean the areas around the discharging roller hoist 7 that are not convenient to clean. A hanging rod 22 is provided on the side of the top of the installation box 2. The hanging rod 22 is in an L-shaped structure. The L-shaped hanging rod 22 is convenient for storing and placing the ash extraction pipe 42.

[0035] When in use:

[0036] First, install the return ash device of the discharging bucket elevator 7 on the side of the discharging bucket elevator 7. At the same time, make the support plate 11 at the same height as the ground on the second floor of the mill. When the staff cleans the accumulated ash around the discharging bucket elevator 7, at this time, the electric push rod 5 controls the installation box 2 to move upward, so that the return ash box 1 is in the return ash state. Then, the motor 31 in the air guiding mechanism 3 drives the rotating rod 32 and the vortex blade 33 to rotate, generating suction at the return ash port 111 in the middle of the support plate 11. In this way, the staff can sweep the accumulated ash into the return ash port 111, and the accumulated ash entering the return ash box 1 through the return ash port 111 will enter the interior of the discharging bucket elevator 7 from the ash outlet 12. In this way, the labor intensity of the staff for cleaning the accumulated ash can be reduced;

[0037] During use:

[0038] When there is accumulated ash around the discharging bucket elevator 7 that is inconvenient to clean, the electric push rod 5 controls the installation box 2 to move downward, so that the return ash box 1 is in the ash pumping state. At this time, the ash pumping nozzle 43 in the ash pumping mechanism 4 will generate suction. At this time, the staff can hold the ash pumping nozzle 43 to pump out the accumulated ash around the discharging bucket elevator 7 that is inconvenient to clean, which is beneficial to improving the effect of ash return cleaning of the device.
