[0027] Example 1

[0028] See attached Figure 1-8The present application provides a combustion exhaust gas purification device, including a burner body 1, an activated carbon replacement device 2, a trigger device 3 and an activated carbon transition box 4, wherein the burner body 1 is connected to the activated carbon replacement device 2 through a first air outlet pipe 5, and the activated carbon replacement device 2 includes a shell 6, a switching box 7, a cylinder 8 and an activated carbon containing box 9, wherein the shell 6 is fixedly connected to the first air outlet pipe 5, the cylinder 8 is fixedly installed on the shell 6, the output end of the cylinder 8 is connected to the switching box 7, the activated carbon containing box 9 is installed in the switching box 7, and the activated carbon containing box 9 stores activated carbon for filtering and purifying exhaust gas, and the cylinder 8 is used to switch the switching box 7 back and forth, thereby achieving the purpose of switching the activated carbon. The activated carbon containing box 9 is provided with a plurality of vent holes 10 at the top and bottom, the other end of the activated carbon replacement device 2 is connected to a second air outlet pipe 11, the first air outlet pipe 5 is connected to a first branch pipe 12, a spring valve 13 is provided in the first branch pipe 12, the spring valve 13 includes a fixed block 14, a valve core 15 and a spring 16, the fixed block 14 is fixedly connected to the first branch pipe 12, the valve core 15 is movably connected to the fixed block 14 and the outer sleeve is provided with the spring 16, the spring 16 is used to push the valve core 15 to block the air inlet of the first branch pipe 12, so that under normal circumstances, the exhaust gas cannot flow in from the first air outlet pipe 5, the first branch pipe 12 is connected to the trigger device 3, and the trigger device 3 includes a trigger box body 1 7. A lever 18, a momentary switch 19, and a tension spring 20. The trigger box body 17 is fixedly connected to the first branch pipe 12. The lever 18 is rotatably connected to the first branch pipe 12. The lever 18 includes a paddle 22 and a shift block 23. The paddle 22 is arranged in the first branch pipe 12. The momentary switch 19 is connected to the trigger box body 17. The momentary switch 19 is electrically connected to the cylinder 8. The momentary switch 19 is used to control the operation of the cylinder 8. One end of the tension spring 20 is connected to the lever 18, and the other end is connected to the trigger box body 17. In the initial state, the lever 18 is away from the momentary switch 19 under the tension of the tension spring 20. The paddle 22 is horizontally stationary under the tension of the tension spring 20. The trigger device 3 is connected to the activated carbon transition box 4 through a pipe, and the activated carbon transition box 4 is connected to the second air outlet pipe 11 through the second branch pipe 21. The activated carbon transition box 4 is used to filter the exhaust gas that flows into the first branch pipe 12 after saturation. When working, the installed spring 16 is in a compressed state, and its elastic force presses the valve core 15 to block the air inlet at the first branch pipe 12, so that under normal circumstances, the exhaust gas cannot flow into the first branch pipe 12. The exhaust gas generated by the burner body 1 flows from the first air outlet pipe 5 through the activated carbon holding box 9 for purification and filtration to meet the standards and is discharged through the second air outlet pipe 11. When the activated carbon in the activated carbon holding box 9 is saturated with adsorption, the exhaust gas is blocked in the first air outlet pipe 5 and accumulated.The increased pressure pushes the valve core 15 to squeeze the spring 16 to contract, so that the exhaust gas continuously flows into the first branch pipe 12 and flows through the trigger device 3. The exhaust gas pushes the paddle 22 to rotate around the first branch pipe 12, so that the lever 18 rotates, and then the shift block 23 rotates to trigger the inching switch 19, so that the cylinder 8 works to switch the activated carbon storage box 9, and the exhaust gas flowing through the trigger device 3 is filtered by the activated carbon transition box 4 and flows into the second outlet pipe 11 through the second branch pipe 21 for discharge. After the activated carbon storage box 9 is switched, the exhaust gas can flow through the new activated carbon for filtration, and the air pressure at the first outlet pipe 5 is restored to the original state. Obviously, the valve core 15 blocks the air inlet again under the elastic force of the spring 16. The present application can automatically replace the activated carbon when the burner is operating without stopping the work, making the replacement of activated carbon more convenient and safe, improving efficiency, and having a simple structure.

[0029] Specifically, the first branch pipe 12 is provided with a stop shoulder 201, and one side of the valve core 15 presses against the stop shoulder 201 to block the exhaust gas, which has a simple structure and is not easy to get stuck.

[0030] Specifically, the first branch pipe 12 is provided with a slope 24, and the slope 24 blocks half of the first branch pipe 12 and is tilted, so that the exhaust gas flows through the slope 24 and flows toward the blade 22 with a faster speed and increased pressure, thereby better driving the blade 22 to rotate and then driving the shift block 23 to trigger the moment switch 19, and the structure is simple and ingenious.

[0031] Specifically, the top of the switching box 7 is open, and a partition 25 is vertically provided in the middle to divide the switching box 7 into two chambers. A circular hole 26 is opened at the bottom of each chamber. The activated carbon holding box 9 is installed in the chamber and is divided into a connecting rod chamber by the partition 25 to prevent exhaust gas from contaminating the activated carbon. The switched chamber is convenient for personnel to replace new activated carbon. The structure is simple and easy to operate.

[0032] Preferably, the outer shell 6 is provided with a guide block 27, the switching box 7 is provided with a groove 28, and the guide block 27 is provided with a protrusion that cooperates with the groove 28. The guide block 27 guides to prevent the switching box 7 from shifting when switching back and forth. Through the cooperation of the protrusion and the groove 28, the switching box 7 can be moved close to the bottom plate of the outer shell 6 to prevent exhaust gas leakage. The structure is simple and easy to maintain.

The pick-and-place door 29 and the shell 6 are arranged to prevent air leakage. The pick-and-place door 29 is provided with a handle 31. When the activated carbon needs to be replaced, the handle 31 is manually lifted to open the pick-and-place door 29 to replace the activated carbon, which is convenient for replacing the activated carbon and simple to operate.

[0035] Specifically, the activated carbon containing box 9 is provided with a threaded hole 32. When taking out and placing the activated carbon containing box 9, a bolt or a handle with an external thread is screwed into the threaded hole 32. After taking out or placing, the bolt or handle can be removed. The operation is convenient, and it does not cause structural interference, which is more practical.

[0036] Preferably, the housing 6 is provided with an alarm light 33, and the alarm light 33 is electrically connected to the moment switch 19. When the moment switch 19 is triggered, the alarm light 33 sends out an alarm to remind personnel to replace the activated carbon, thereby improving efficiency and preventing personnel from forgetting to replace new activated carbon.

[0037] Specifically, the activated carbon transition box 4 includes an outer box body 34 and a drawer cage 35. The drawer cage 35 is connected to the outer box body 34 by plugging and unplugging.
