Detailed implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 2 . Figure 3 And Figure 4 , an embodiment provided by the present invention: a slag treatment device for a domestic waste low-temperature pyrolysis gasification device, including a slag bucket 1. A servo motor 3 is fixedly connected to the right top of the slag bucket 1. The output end of the servo motor 3 is fixedly connected to a driving gear 4. A fixed shell 5 is fixedly connected to the middle right side of the slag bucket 1. The left side of the inner bottom wall of the fixed shell 5 is rotatably connected to a driven gear 6. The driving gear 4 is meshed with the driven gear 6. A spline rod 7 is fixedly installed on the inner wall of the driven gear 6. The middle of the spline rod 7 penetrates through the right side of the slag bucket 1. The left end of the spline rod 7 is fixedly connected to a connecting rod 8. Both the upper and lower sides of the connecting rod 8 are fixedly connected to a cleaning shell 9. On the far side of the inner walls of the two cleaning shells 9, two return springs 10 are fixedly connected respectively. The far sides of the plurality of return springs 10 are fixedly connected to cleaning brushes 11. A support frame 12 is fixedly connected to the bottom wall of the slag bucket 1. The right side of the bottom wall of the slag bucket 1 is communicated with a discharge shell 13. The right end of the spline rod 7 is rotatably connected to a limiting L-shaped plate 20. The left side of the inner cavity at the bottom of the support frame 12 is fixedly connected to an electric telescopic rod 21. The output end of the electric telescopic rod 21 is fixedly connected to the bottom of the L-shaped plate 20. A collection device 2 is arranged on the left side of the inner bottom wall of the support frame 12;

[0032] Specifically, the startup of the servo motor 3 ensures that the driven gear 6 can be accurately driven by the driving gear 4. When the driving gear 4 starts to rotate, the driven gear 6 rotates stably on the left side of the inner wall of the fixed housing 5. As the driven gear 6 rotates, the spline on the spline rod 7 can achieve coaxial rotation with the driven gear 6 and can also limit the translational movement of the spline rod 7. The slag discharge bucket 1 is threadedly connected to the spline rod 7. The right side of the spline rod 7 is rotatably connected to a limiting L-shaped plate 20. By restricting the displacement of the L-shaped plate 20, a fixed restriction can be provided to the spline rod 7. Under this fixation, the spline rod 7 completes rotation, and then the electric telescopic rod 21 drives the displacement of the limiting L-shaped plate 20 and the sliding connection at the right bottom of the support frame 12 to enable the spline rod 7 to complete rotation and translation simultaneously, providing the possibility for the subsequent cleaning process. When the spline rod 7 rotates and displaces, the connecting rod 8 also rotates accordingly. The function of the connecting rod 8 is to convert the linear displacement of the spline rod 7 into the rotational displacement of the two cleaning shells 9. This design enables the cleaning shells 9 to rotate along the inner wall of the slag discharge bucket 1, thereby achieving comprehensive cleaning of the inner wall. Inside the cleaning shell 9, the cleaning brush 11 fixedly connected by the return spring 10 plays a key role. When the cleaning shell 9 rotates, the cleaning brush 11 also rotates and displaces. Due to the elastic extrusion of the return spring 10, the cleaning brush 11 can closely adhere to the inner wall of the slag discharge bucket 1, ensuring the maximization of the cleaning effect. This design avoids the situation where slag adheres to the inner wall of the slag discharge bucket 1 and affects the discharge, improving the operating efficiency of the equipment.

[0033] Refer to Figure 1 , a rubber ring 206 is fixedly installed on the outer wall of the conveying pipe 202, and the outer wall of the rubber ring 206 is fixedly connected to the bottom wall of the slag discharge bucket 1; two support plates 16 are fixedly connected to the front and rear bottom sides of the support frame 12, and the inner walls of the multiple support plates 16 are all threadedly connected with threaded knobs 17; rubber pads 18 are fixedly connected to the middle parts of the multiple threaded knobs 17;

[0034] Specifically, the rubber ring 206 enables the protection of the connection part of the conveying pipe 202. The support plates 16 and the threaded knobs 17 facilitate the fixed installation of the device. The rubber pads 18 enable the protection of the support plates 16 and reduce the rotational damage of the threaded knobs 17.

[0035] Refer to Figure 1 、 Figure 3 and Figure 4, the collection device 2 includes a power blower 201. The bottom wall of the power blower 201 is fixedly connected to the left side of the inner bottom wall of the support frame 12. The output end of the power blower 201 is communicated with a delivery pipe 202. The top end of the delivery pipe 202 penetrates through the bottom wall of the slag discharge bucket 1 and is communicated with an annular spray pipe 203. The outer wall of the annular spray pipe 203 is fixedly connected to the left side of the inner wall of the slag discharge bucket 1. The extraction end of the power blower 201 is communicated with an extraction pipe 204. The right end of the extraction pipe 204 is communicated with a collection box 205. A filter plate 207 is fixedly installed on the inner wall of the collection box 205. The top wall of the collection box 205 is communicated with the bottom wall of the discharge shell 13;

[0036] Specifically, when the power blower 201 starts to work, its strong suction will extract the surrounding air and eject the air through the delivery pipe 202 and the annular spray pipe 203. These ejected airflows form a powerful force, which can effectively cooperate with the cleaning brush 11 to carry out the slag cleaning work. The airflow generated by the power blower 201 can blow away those stubborn slag, making it easier to be captured and removed by the cleaning brush 11. The cooperation between this airflow and the cleaning brush 11 makes the cleaning work more efficient, and at the same time reduces the difficulty and intensity of manual cleaning. During the cleaning process, the removed slag will be discharged through the discharge shell 13. When the extraction end of the power blower 201 is opened, the collection box 205 can cooperate with the filter plate 207 to work, uniformly collect and process the cleaned slag. This design not only avoids the situation that the slag is scattered and not easy to collect, but also makes the whole cleaning process more environmentally friendly and energy-saving.

[0037] Refer to Figure 1 and Figure 3 , at the top of the front side of the support frame 12, a control switch 14 is fixedly connected. The control switch 14 is electrically connected to the servo motor 3, the electric telescopic rod 21 and the power blower 201 respectively; a protective cover 15 is arranged on the left side of the control switch 14. The rear side of the protective cover 15 is rotatably connected to the left end of the front side of the support frame 12 through a hinge; an observation window 19 is fixedly installed on the front side of the slag discharge bucket 1;

[0038] Specifically, through the control switch 14 which is electrically connected to the servo motor 3, the electric telescopic rod 21 and the power blower 201 respectively, the control switch 14 can complete the opening and closing of the device. Through the protective cover 15, the control switch 14 can be protected and prevented from being accidentally touched. Through the observation window 19, the discharge situation can be directly observed.

[0039] Working principle: When starting to use for cleaning, by starting the servo motor 3, the driven gear 6 is driven by the driving gear 4. Then, the driven gear 6 rotates on the left inner wall of the fixed housing 5. The spline on the spline rod 7 can achieve coaxial rotation of the rod and the driven gear 6, and can also limit the translational movement of the spline rod 7. Through the connection between the slag discharge bucket 1 and the spline rod 7, the right side of the spline rod 7 is rotatably connected to the limiting L-shaped plate 20. Under the drive of the electric telescopic rod 21 and the sliding limit of the support frame 12 for the limiting L-shaped plate 20, the spline rod 7 can complete displacement while rotating, thereby driving the connecting rod 8 to rotate, and enabling the two cleaning shells 9 and the cleaning brushes 11 fixedly connected to the inside through the return springs 10 to rotate and displace together, completing the rotational cleaning of the inner wall of the slag discharge bucket 1. Through the elastic extrusion of multiple return springs 10, the cleaning brushes 11 can closely adhere to the inner wall of the slag discharge bucket 1, thereby improving the cleaning effect, avoiding the situation that the material slag adheres to the inner wall of the slag discharge bucket 1 and affects the discharge, improving the discharging efficiency, and by starting the power blower 201, the air is extracted and sprayed through the conveying pipe 202 and the annular nozzle 203, so that the formed air flow can cooperate with the cleaning brushes 11 to carry out the slag cleaning work, improving the cleaning efficiency. The material slag removed by the cleaning brushes 11 is discharged through the discharge shell 13. By connecting the collection box 205, when the extraction end of the power blower 201 is opened, the collection box 205 and the filter plate 207 can uniformly collect and process the cleaned material slag, avoiding the situation that the material slag is scattered and not easy to collect.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
