[0022] The following will be combined with the drawings of the specification 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.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a waste incineration fly ash treatment equipment with an anti-backflow structure, including a treatment box 1, the outer wall of the treatment box 1 is fixedly connected to a first connecting pipe 2, the upper surface of the first connecting pipe 2 is fixedly connected to a first pipe 3, the inner wall of the first pipe 3 is slidably connected to a sealing plate 4, the lower surface of the sealing plate 4 is fixedly connected to a connecting column 5, the lower surface of the sealing plate 4 is fixedly connected to one end of a first spring 6, the other end of the first spring 6 is fixedly connected to the inside of the first connecting pipe 2, the outer wall of the first pipe 3 is fixedly connected to a second pipe 7, the outer wall of the second pipe 7 is fixedly connected to the inside of the treatment box 1, and the outer wall of the treatment box 1 is provided with a water supply component, which is used to spray the inside of the treatment box 1.

[0024] Specifically, the fly ash airflow after incineration passes through the second connecting pipe 20 and enters the interior of the treatment box 1 for treatment. The fly ash airflow is filtered through the filter plate 13, and the filtered fly ash airflow passes through the second pipe 7 and enters the interior of the first pipe 3. At this time, the airflow will produce a downward pressure on the sealing plate 4, so that the sealing plate 4 slides on the inner wall of the first pipe 3, and the first spring 6 is squeezed by the sliding of the sealing plate 4, thereby discharging the treated fly ash airflow from the interior of the first connecting pipe 2. When the sealing plate 4 is not under force, it will slide in the opposite direction to seal the first connecting pipe 2 and the first pipe 3, which can effectively prevent the fly ash airflow from flowing back to the interior of the treatment box 1, thereby achieving the effect of preventing backflow.

[0025] Reference Figure 1 and Figure 3The water supply assembly includes a water tank 8, the outer wall of the water tank 8 is fixedly connected to the outer wall of the treatment box 1, the upper surface of the water tank 8 is fixedly connected to a water pump 9, the output end of the water pump 9 is fixedly connected to a hose 10, and the lower surface of the hose 10 is fixedly connected to a nozzle 21.

[0026] Specifically, the water pump 9 is started, and the water pump 9 pumps the water in the water tank 8 into the inside of the hose 10 , and the hose 10 sprays water into the inside of the treatment box 1 through the nozzle 21 .

[0027] Reference Figure 1 、 Figure 3 and Figure 4 The outer wall of the hose 10 is fixedly connected to the top cover 11, the outer wall of the top cover 11 is slidably connected to the inner wall of the processing box 1, the upper surface of the top cover 11 is fixedly connected to the handle 12, the inner wall of the processing box 1 is slidably connected to the filter plate 13, and a slot 19 is opened inside the processing box 1. The outer wall of the processing box 1 is fixedly connected to the second connecting pipe 20, and a slide groove 14 is opened inside the filter plate 13. The interior of the filter plate 13 is slidably connected with a slide rod 15, and the lower surface of the slide rod 15 is fixedly connected to a fixing column 16. The outer wall of the fixing column 16 is slidably connected to the inner wall of the slide groove 14, the outer wall of the fixing column 16 is fixedly connected to one end of the second spring 17, the other end of the second spring 17 is fixedly connected to the inner wall of the slide groove 14, the outer wall of the fixing column 16 is fixedly connected to a block 18, the outer wall of the block 18 is slidably connected to the inner wall of the slide groove 14, and the outer wall of the block 18 is slidably connected to the inner wall of the slot 19.

[0028] Specifically, the top cover 11 can be slid out from the inner wall of the processing box 1 through the handle 12. At this time, the slide rod 15 can be slid. During the sliding process of the slide rod 15, the fixed column 16 will be driven to slide on the inner wall of the slide groove 14. The second spring 17 will be squeezed by the sliding of the fixed column 16, and the block 18 can be slid out from the inner wall of the slot 19, thereby sliding on the inner wall of the slide groove 14, sliding the filter plate 13 out of the inside of the processing box 1, and the filter plate 13 can be quickly disassembled.

[0029] Working principle: When the device needs to be used, the fly ash airflow will flow to the interior of the treatment box 1 through the second connecting pipe 20 and be filtered through the filter plate 13. The water pump 9 is started, and the water pump 9 will transport the water in the water tank 8 to the interior of the nozzle 21 through the hose 10 to spray the interior of the treatment box 1 to reduce dust. The fly ash airflow filtered by the filter plate 13 will be transported to the interior of the first pipe 3 through the second pipe 7. At this time, the airflow will generate a pressure on the sealing plate 4, driving the sealing plate 4 to slide on the inner wall of the first pipe 3. When the sealing plate 4 slides, it will compress the first spring 6, and the connecting column 5 can play a limiting role to prevent the sealing plate 4 from sliding out of the inner wall of the first pipe 3. The sliding of the sealing plate 4 can transport the fly ash airflow inside the first pipe 3 to the interior of the first connecting pipe 2 for discharge. When the sealing plate 4 is no longer under force, it will play a sealing role between the first pipe 3 and the first pipe 3, which can effectively prevent the airflow inside the first connecting pipe 2 from flowing back to the interior of the first pipe 3, thereby achieving the effect of anti-backflow. Since the filter plate 13 needs to be replaced frequently during use, when the filter plate 13 needs to be replaced, the top cover 11 is slid out from the inner wall of the treatment box 1 through the hose 10, and the sliding rod 15 is slid. The sliding rod 15 will slide on the inner wall of the slide groove 14. When the slide groove 14 slides, it will drive the fixing column 16 to slide on the inner wall of the slide groove 14 and squeeze the second spring 17, thereby driving the block 18 to slide inside the treatment box 1 and the filter plate 13, and slide the block 18 out from the inner wall of the card groove 19, and take out the filter plate 13 for replacement. When the filter plate 13 needs to be installed, the slide rod 15 is pushed and the second spring 17 is squeezed through the fixing column 16. When the block 18 slides to the position of the slot 19, the second spring 17 is no longer under force. At this time, the second spring 17 will rebound and clamp the block 18 into the slot 19, thereby achieving the effect of quickly installing and disassembling the filter plate 13 for use. This device can not only effectively prevent the fly ash airflow from flowing back into the processing box 1, but also achieve the effect of quickly disassembling the filter plate 13 and facilitating use.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
