[0003] At present, after the grille of the rotary grille machine filters out slag, the waste residue will enter the slag receiving structure and then be transported to the slag collecting hopper by the screw conveyor in the slag receiving structure. However, it is difficult for all the waste residue on the grille of the existing rotary grille machine to fall into the slag receiving structure, resulting in waste residue remaining on the grille. The remaining waste residue is likely to enter the water again and enter the subsequent process links, failing to play its due role in intercepting waste residue and affecting the subsequent processes. For this reason, we propose a self-cleaning device for a rotary grille machine. Content of the Utility Model

[0027] Embodiment 1

[0028] Please refer to Figures 1 - 4 As shown in the figure, the present utility model provides a technical solution: a self-cleaning device for a rotary grille machine, including: a body 1, a rotating rod 16, and a liquid passing pipe 14;

[0029] The upper and lower ends of the inner cavity of the body 1 are respectively movably connected by bearings to a driving chain roller 15 and an auxiliary chain roller 11. A grid chain plate 9 is sleeved on the outer sides of the driving chain roller 15 and the auxiliary chain roller 11. Equally spaced rotary barbs 10 are fixedly connected to the outer side of the grid chain plate 9. A slag discharge pipe 2 is provided at the bottom of the right end of the body 1. A driving motor 21 is fixedly installed at the front end of the right side of the body 1. The rotating rod 16 is movably connected to the upper end of the inner cavity of the body 1 through a bearing. A cleaning roller brush 17 is fixedly connected to the outer surface of the rotating rod 16. Sprockets 20 are fixedly connected to the output end of the driving motor 21, the front surfaces of the driving chain roller 15 and the rotating rod 16. A chain 19 is sleeved on the outer side of the sprocket 20. A plurality of equally spaced spray heads 18 are provided at the lower ends of the two liquid passing pipes 14. The liquid passing pipe 14 is located at the right end inside the grid chain plate 9 and is fixedly connected to the front and rear sides of the inner cavity of the body 1. L-shaped support plates 5 are fixedly connected to the front and rear sides of the body 1. An electric control box 3 is fixedly installed at the upper end of the front surface of the L-shaped support plate 5 on the front side of the body 1. And the output end of the electric control box 3 is electrically connected to the input ends of the pump 6 and the driving motor 21 through wires. The lower end inside the L-shaped support plate 5 is fixedly connected to a bottom plate 4. A pump 6 is fixedly installed at the left end of the top of the bottom plate 4. The liquid inlet end of the pump 6 is communicated with a filter mesh cover 7 through a pipeline. The filter mesh cover 7 is a rectangular metal filter mesh. The liquid outlet end of the pump 6 is communicated with the rear side of the liquid passing pipe 14 through a pipeline.

[0030] After this device is installed at the using position by the L-shaped support plate 5 and the bottom plate 4, the control box 3 is used to turn on the device for operation. Then, with the assistance of the sprocket 20 and the chain 19, the driving motor 21 can drive the driving chain roller 15 and the rotating rod 16 to rotate. During the rotation of the driving chain roller 15, with the assistance of the auxiliary chain roller 11, the grille chain plate 9 and the rotary barbs 10 can be driven to rotate, so as to convey the waste residue to the upper end of the machine body 1. When the waste residue reaches the highest point in the machine body 1, the grille chain plate 9 and the rotary barbs 10 turn downward, and then, under the action of gravity, the waste residue can finally be discharged outwards through the slag discharge pipe 2. When the rotating rod 16 rotates, it can drive the cleaning roller brush 17 to clean the filtering surface of the turned-over grille chain plate 9 and the rotary barbs 10. At the same time, the pump 6 can suck the filtered water body through the filter screen cover 7 and transport it into the liquid passing pipe 14 to be discharged outwards by the nozzle 18, so as to realize the reverse backwashing of the filtering surface of the rotating grille chain plate 9, thereby quickly removing the residual waste residue on the grille chain plate 9 and avoiding affecting the subsequent processes.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, as shown in the present utility model Figures 1 - 2 it is disclosed that a protective cover 8 is fixedly connected between the outer side of the chain 19 and the front end of the right side of the machine body 1, and the protective cover 8 is made of stainless steel.

[0033] Through the arrangement of the protective cover 8 in this technical solution, a protective structure can be formed on the outer side of the chain 19, improving the safety of this device during use.

[0034] Embodiment 3

[0035] On the basis of Embodiment 1, as shown in the present utility model Figure 3 it is disclosed that a partition plate 12 is fixedly connected to the inner side of the machine body 1, and the partition plate 12 is inclined. The right end of the bottom of the partition plate 12 and the corresponding position of the left end of the inner wall of the machine body 1 where the slag discharge pipe 2 is located are fixedly connected with a filter screen plate 13. The filter screen plate 13 is inclined, and the inclination angle of the filter screen plate 13 is between 120 degrees and 160 degrees.

[0036] Through the arrangement of the partition plate 12 in this technical solution, the interior of the machine body 1 can be divided into two sections. And through the arrangement of the filter screen plate 13, when the filtering surface of the grille chain plate 9 is reversely flushed by high-pressure water, the flushed waste residue and water can be quickly separated on the filter screen plate 13. The inclined filter screen plate 13 can make the waste residue automatically move towards the slag discharge pipe 2 under the influence of gravity, and the water after filtration and separation can flow back into the water body sucked by the pump 6 again through the inner wall of the machine body 1.
