Problems solved by technology

It is difficult for traditional mixers to automatically adjust the mixing method according to the water content of hazardous waste. If the auxiliary method of liquid mixing is used, it is easy to cause combustion or even explosion of hazardous waste, as well as damage to the mixing mechanism.
[0003] Chinese patent (authorized announcement number: CN209507940U) discloses a hazardous waste sludge treatment mixer, a hazardous waste sludge treatment mixer, through the improvement of the stirring mechanism, and the use of humidity sensors, vibration exciters and temperature detection mechanisms, The mixer can automatically adjust the mixing according to the water content of hazardous waste; however, there are some practical defects in this patent. The patent does not disclose the principle of effective detection of water quality, nor does it give a specific treatment method

Abstract

The invention relates to the related field of environmental protection, and concretely relates to a hazardous waste sludge separation type treatment device. The device comprises a sludge conveying frame, a sludge treatment box and a sewage treatment box, a conveying cylinder and a water accumulation tank are arranged on the sludge material conveying frame, the water accumulation tank is mounted onthe outer layer of the conveying cylinder in a wrapping manner, a dredge pump joint is mounted at the bottom end of the conveying cylinder, a plurality of water outlet holes are formed in the outer wall of the conveying cylinder, a spiral auger is installed in the conveying cylinder, a discharging end is arranged at the top of the conveying cylinder, a conical structure is arranged at the discharging end, the inner diameter of the cylinder wall of the conical structure is gradually reduced, a discharging port is arranged at the side edge of the top of the discharging end, and a conveying pumpis mounted at the discharging port. The device firstly separates a water liquid from the sludge, and then separately treats the water liquid and the sludge, so that the flammable and combustible risks of the hazardous waste sludge are avoided.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a hazardous waste sludge separation treatment device. Background technique [0002] Hazardous waste refers to solid and liquid waste with one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity or infectivity. Generally include: waste acid and alkali waste, metals, organics, residues, etc. Hazardous waste is a type of waste that is relatively difficult to dispose of. It is difficult for traditional mixers to automatically adjust the mixing method according to the water content of hazardous waste. If liquid mixing is used for assistance, hazardous waste may burn or even explode, and the mixing mechanism may be damaged. [0003] Chinese patent (authorized announcement number: CN209507940U) discloses a hazardous waste sludge treatment mixer, a hazardous waste sludge treatment mixer, through the improvement of the stirring mechanism, an...
