Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to a gas exhaust device temporarily covering a garbage landfill. Background Art

[0002] Sanitary landfills for domestic waste mainly collect domestic waste. Some organic components in domestic waste will produce a large amount of landfill gas after a long period of fermentation and decomposition. In order to avoid the serious impact of disorderly landfill gas emissions on the environment and to prevent rainwater from entering the garbage pile and becoming leachate, HDPE membrane is used to temporarily cover the domestic waste pile. However, after temporary covering, the landfill gas in the garbage pile cannot be discharged naturally, causing combustible gas to accumulate under the membrane, which poses certain safety hazards. In order to achieve the comprehensive utilization of landfill gas in the temporary covering system and avoid the accumulation of landfill gas to form dangerous gas bags, a gas exhaust system needs to be set on the temporary covering system.

[0003] The existing temporary covering system's drainage system lacks a gas disinfection pretreatment structure, which causes various harmful gases to concentrate in a confined space for a long time and expand, posing a risk of explosion and posing certain risks to workers. Based on the existing technical deficiencies, the utility model designs a gas drainage device for temporary covering of a landfill. Utility Model Content

Since the rotating rod 26 is connected to the two stirring rods 214 through the second connecting rod 212, and the clamping wheel 213 is slidably clamped in the ring plate 29, the rotating rod 26 can drive the two stirring rods 214 to make a circular motion inside the ring plate 29 when rotating.
