[0003] The gas delivery components of the waste incinerator will have a large amount of particulate matter that needs to be filtered during the gas delivery process. After long-term use, particulate matter will accumulate on the filter plate, causing the filter efficiency of the filter plate to decrease. Since the filter plate is inside the gas delivery pipe, the cleaning and maintenance of the filter plate is very time-consuming and labor-intensive. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A gas delivery component for a waste incinerator: comprising a waste incinerator body 1, an exhaust pipe A11 fixedly connected to the surface of the waste incinerator body 1, a filter pipe 12 fixedly connected to the surface of the exhaust pipe A11, an exhaust pipe B13 fixedly connected to the surface of the filter pipe 12, the gas released by the waste incinerator body 1 will pass through the exhaust pipe A11, the filter pipe 12 and the exhaust pipe B13 in sequence, the exhaust pipe A11, the filter pipe 12 and the exhaust pipe B13 transport and discharge the gas, the bottom of the filter pipe 12 is threadedly connected to an internal threaded pipe 14, the top of the filter pipe 12 is slidably connected to a piston rod 16, the bottom of the internal threaded pipe 14 is fixedly connected to a collecting cylinder 15, the bottom of the piston rod 16 is fixedly connected to a filter disc 17, the filter disc 17 can filter out particulate matter in the gas, the top of the piston rod 16 is fixedly connected to a spring 18, the bottom of the spring 18 is fixedly connected to the upper surface of the exhaust pipe B13, the filter disc The plate 17 is slidably connected to the inner surface of the filter tube 12, and a fixing ring 2 is fixedly connected to the surface of the exhaust pipe B13. A support rod 21 is fixedly connected to the surface of the fixing ring 2. The top of the support rod 21 is fixedly connected to the limiting plate 22, and a fixing nut 23 is fixedly connected to the surface of the support rod 21. The surface of the fixing nut 23 is threadedly connected to the limiting bolt 24. The gas delivery component of the waste incinerator can remove the filter disc 17 from the inside of the filter tube 12 to the bottom of the filter tube 12 for cleaning and maintenance, which greatly reduces the difficulty of cleaning the filter disc 17 and saves maintenance time. The maintenance personnel can operate it very time-saving and labor-saving. Moreover, when the filter disc 17 moves to the bottom of the filter tube 12, the filter disc 17 can bring out the particulate matter on the inner surface of the filter tube 12, completing the cleaning of the inner surface of the filter tube 12, optimizing the cleaning steps, and improving the comprehensiveness of the maintenance work.

[0024] Furthermore, the exhaust pipe A11 and the exhaust pipe B13 are parallel to the horizontal plane, the filter pipe 12 is perpendicular to the horizontal plane, and the horizontal height of the exhaust pipe B13 is higher than the horizontal height of the exhaust pipe A11. The gas inside the exhaust pipe A11 will rise to the exhaust pipe B13 through the filter pipe 12, and the particulate matter will fall to the bottom of the filter pipe 12.

[0025] Furthermore, an external thread is provided at the bottom of the filter tube 12, and the internal threaded tube 14 is threadedly connected to the external thread of the filter tube 12. The collecting tube 15 is threadedly connected to the bottom of the filter tube 12 through the internal threaded tube 14. All the particulate matter will fall into the inside of the collecting tube 15, and the collecting tube 15 can be removed from the bottom of the filter tube 12 through the internal threaded tube 14, thereby facilitating the cleaning of the particulate matter inside the collecting tube 15.

[0026] Furthermore, the elastic force of the spring 18 acts on the piston rod 16, and a guide hole is opened at the top of the filter tube 12. The piston rod 16 slides on the guide hole of the filter tube 12, and the sliding of the piston rod 16 adopts dynamic sealing technology and has a self-locking seal to ensure the sealing inside the filter tube 12. The filter disc 17 slides and rises on the inner surface of the filter tube 12 through the piston rod 16. The spring 18 supports the height of the filter disc 17 inside the fixed ring 2 through the piston rod 16, thereby ensuring the horizontal height of the filter disc 17 inside the fixed ring 2.

[0027] Furthermore, the length of the filter tube 12 is less than the length of the piston rod 16, and the filter disc 17 can slide out from the bottom of the filter tube 12. Before the filter disc 17 slides out, the collecting cylinder 15 needs to be removed in advance. After the filter disc 17 slides out of the filter tube 12, it is convenient to directly clean and maintain the filter disc 17.

[0028] Furthermore, the fixing ring 2 supports the support rod 21 on the exhaust pipe B13, and the support rod 21 supports the limit plate 22 and the fixing nut 23. The limit plate 22 limits the piston rod 16 from continuing to slide upward directly above the piston rod 16. The gas will blow the filter disc 17 to slide upward on the inner surface of the filter tube 12, and the limit plate 22 limits the filter disc 17 from continuing to move upward through the piston rod 16, ensuring that the position of the filter disc 17 inside the filter tube 12 is relatively stable.

[0029] Furthermore, the support rod 21 is perpendicular to the surface of the exhaust pipe B13, the limit bolt 24 and the support rod 21 are perpendicular to each other, and the support rod 21 and the filter tube 12 are parallel to each other. The limit bolt 24 changes the position of the limit bolt 24 on the support rod 21 by rotating on the fixing nut 23. The horizontal height of the limit bolt 24 is higher than the top of the filter tube 12. When the piston rod 16 slides to the bottom, the spring 18 is squeezed and deformed. At this time, the limit bolt 24 contacts the upper surface of the piston rod 16, limiting the sliding of the piston rod 16 on the filter tube 12, thereby ensuring the position of the filter disc 17 at the bottom of the filter tube 12.

[0030] Working principle: The gas discharged from the inside of the waste incinerator body 1 is transported through the exhaust pipe A11, the filter pipe 12 and the exhaust pipe B13. The filter disc 17 filters the gas inside the filter pipe 12, and the filtered particles fall into the collection tube 15. The collection tube 15 can be removed from the bottom of the filter pipe 12 through the internal threaded tube 14, so as to clean the collection tube 15. The filter disc 17 is driven by the piston rod 16 to slide to the bottom of the filter pipe 12. The filter disc 17 can take away the particles attached to the inner surface of the filter pipe 12, and the filter disc 17 can slide out from the bottom of the filter pipe 12. At this time, the spring 18 is squeezed and deformed. At this time, the limiting bolt 24 is rotated on the fixing nut 23 so that the limiting bolt 24 is on the surface of the piston rod 16. The limiting bolt 24 limits the position of the piston rod 16 on the filter tube 12, and then limits the position of the filter disc 17 at the bottom of the filter tube 12. At this time, the filter disc 17 is convenient for the staff to clean and maintain it. The filter disc 17 can be taken out from the inside of the filter tube 12 to the bottom of the filter tube 12 for cleaning and maintenance, which greatly reduces the difficulty of cleaning the filter disc 17, saves maintenance time, and is very time-saving and labor-saving for maintenance personnel to operate.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
