The present invention discloses a sludge feeding device, comprising: a sludge pushing power device, used to receive sludge and transport it to an incinerator through a sludge pushing channel; a variable diameter sludge discharging device, used to receive the sludge output from the sludge pushing power device, and increase or decrease the sludge passing capacity entering the incinerator; an isolation pushing device, which pushes the sludge coming out of the variable diameter sludge discharging device into the incinerator; an auxiliary unblocking device, used to clear the blocked channel; a coordination control system, used to control the sludge pushing power device, the variable diameter sludge discharging device, the isolation pushing device and the unblocking device to coordinately send the sludge into the incinerator. The present invention sends the sludge that has undergone preliminary pressure filtration into the boiler, so that the sludge is not dried, has no odor diffusion, does not affect the surrounding environment, and can be controlled to enter the furnace for incineration in real time.

The utility model relates to battery disposal equipment technical field provides a kind of waste battery disposal cabinet, the disposal cabinet includes cabinet, cover and insulating pad. Among them, cabinet includes bottom wall and side wall, and the first end of side wall is connected with bottom wall and forms accommodating cavity;Cover is detachably covered in the second end of side wall, is suitable for covering accommodating cavity;Insulating pad is pasted on the side of bottom wall and side wall towards accommodating cavity.The waste battery disposal cabinet provided by the utility model, by setting up the cabinet with bottom wall and side wall, the first end of side wall is connected with bottom wall and forms accommodating cavity, waste battery can be placed in accommodating cavity;Cover is detachably covered in the second end of side wall, so that cover can cover accommodating cavity, and insulating pad is pasted on the side of bottom wall and side wall towards accommodating cavity;Make the disposal of waste battery safer, not easy to collide, more cannot be damaged due to collision, so that liquid leakage phenomenon cannot occur, can avoid pollution environment and fire accident, also can prevent the occurrence of electric leakage accident.

The present invention provides a novel method for disposing of spent bleaching earth that is economically advantageous and avoids the problems typically associated with its disposal. By adding fine lime (calcium carbonate) to the spent bleaching earth discharged from the process filters, spontaneous combustion can be eliminated. The material can then be transported in solid form to a production facility for use as a nutrient ingredient in the manufacture of a wide range of poultry and livestock feed products.

This invention discloses a modular cascaded coupled multi-stage treatment system and method for mine wastewater, belonging to the field of environmental water treatment technology. It includes a filtration module filled with filter media for particle removal; an adsorption module filled with composite adsorption media for adsorbing heavy metal and organic pollutants; a reaction module filled with slow-release reaction media for removing heavy metal ions from wastewater through sulfide precipitation and reduction reactions; and a sedimentation module to slow down the reaction time and cause the water flow to reverse vertically. This invention achieves multi-stage synergistic removal of suspended solids, organic matter, and heavy metals from mine wastewater through a combination of sand, fly ash ceramsite, and heavy metal treatment agents; it relies on gravity flow due to the natural slope of the mine shaft for gravity-based operation; its modular design allows for flexible series connection to adapt to different pollution levels; and the semi-open tank facilitates media replacement, with heavy metals solidified in the reaction module, resulting in minimal secondary pollution.
