The invention relates to the field of waste power energy storage battery recycling treatment, in particular to a waste power energy storage battery recycling treatment system which comprises a cracking carbonization kiln and a tail gas treatment unit for treating tail gas generated in the cracking carbonization process of the cracking carbonization kiln, and a material treatment unit is arranged on one side of the inlet end of the cracking carbonization kiln. The waste battery crushed materials are conveyed in a closed mode through a first spiral conveyor, and a cooling kiln is arranged on one side of the outlet end of the cracking carbonization kiln; according to the waste power energy storage battery high-temperature pyrolysis and carbonization system, through the pyrolysis process of two-stage crushing pretreatment, closed spiral conveying, uniform pyrolysis and carbonization in the pyrolysis and carbonization kiln, sealed dynamic discharging and cooling in the cooling kiln, high-temperature pyrolysis and carbonization treatment on the waste power energy storage battery is achieved; and the tail gas in the cracking and carbonizing process is sequentially subjected to dust removal, combustible organic matter removal, acid gas removal and peculiar smell treatment, so that the tail gas is safely discharged after meeting the environment-friendly emission standard.

The invention discloses a ventilation opening adjusting device based on the Internet of Things, and relates to the technical field of ventilation devices.The ventilation opening adjusting device comprises a main body mechanism, the main body mechanism comprises a ventilation fan, one side of the ventilation fan fixedly communicates with a ventilation pipe, and an air opening adjusting mechanism is arranged in the ventilation pipe; the air port adjusting mechanism comprises an inlet adjusting unit, the inlet adjusting unit is located in the ventilation pipe, the inlet adjusting unit is used for independently opening a plurality of gas pipelines so as to achieve classified treatment of different gases, and the inlet adjusting unit is based on the Internet of Things technology, provided with an intelligent sensor and used for monitoring gas types in real time. According to the ventilation opening adjusting device based on the Internet of Things, by arranging the inlet adjusting unit, independent control over the multiple gas treatment pipes can be achieved, so that different pipelines are independently opened to treat different kinds of gas, opening and closing of the corresponding gas inlet covers can be accurately adjusted through the overall structure, and classified treatment of the gas is achieved.

The utility model discloses a device is retrieved with papermaking wastewater belongs to wastewater recovery technical field, including sedimentation tank and the multistage settlement structure of setting in the sedimentation tank, one side of sedimentation tank is equipped with filter equipment still, the top one side of sedimentation tank is equipped with feed cavity, the inner wall fixed connection of feed cavity has guide vane, through the setting of multistage settlement mechanism, first papermaking wastewater and chemical reagent enter the feed cavity in the sedimentation tank, and the guide of guide vane in feed cavity enters the first settlement chamber and settles down, and the papermaking wastewater that settles down through the first settlement chamber enters the second settlement chamber through the height of baffle that adjusting rod adjusts, and the papermaking wastewater that settles down through the second settlement chamber enters the third settlement chamber through the height of baffle that adjusting rod adjusts, through several levels of settlement, make the solid object in the papermaking wastewater that settles down and stay in the bottom of sedimentation tank, effectively prevent the aperture block -up of subsequent filter equipment, effectively improved the efficiency of filtration.

The utility model discloses a water sump coal slime self-discharging device, which relates to the technical field of coal slime cleaning and comprises a sedimentation tank, a sedimentation tank is arranged in the sedimentation tank, two filter screens are mounted on the side wall of the sedimentation tank, a connecting frame is mounted on the upper side of the sedimentation tank, and the top end of the connecting frame is connected with a hanging hook on the bottom side of a chain block. And a sliding piece is mounted at the top end of the chain block and slides on the channel steel track. According to the self-discharging device for the coal slime in the water sump, the setting tank is driven to ascend and descend in the setting pond through the arranged chain block, the setting tank is slowly removed from the water sump, the coal slime in the setting tank can be cleaned by opening the filter screen in the window, the coal slime does not need to be cleaned in the setting pond any more, and rapid, efficient and safe cleaning and discharging of the coal slime are achieved.
