Sludge calorific value conditioning machine

Abstract

The invention discloses a sludge calorific value conditioning machine. The sludge calorific value conditioning machine comprises a rack and a gear motor mounted on one side of the rack, an output shaft of the gear motor is sleeved with a first chain wheel. A center shaft is embedded in the center of the interior of the rack. The central shaft is sleeved with a second chain wheel at a position parallel to the first chain wheel; the second chain wheel is rotatably connected to the first chain wheel through a chain; a plurality of air pipes are transversely embedded into a side edge of the interior of the rack, a turntable is adopted to drive materials to operate, a scraping plate is used for scraping the materials to a next layer of turntable, a temperature and humidity control system is arranged, the sludge is air-dried by dry air, sludge calorific value can be better kept, by adopting a floating scraping plate structure, the scraping plate droops to contact the surface of the turntableby self weight, the requirement on the turntable flatness is low, meanwhile materials are not easy to block and equipment is not easy to damage when large materials exist, and a video monitoring system is arranged to monitor feeding and discharging in real time so as to judge whether the materials run smoothly and whether the inlet and the outlet are blocked.

Description

technical field [0001] The invention relates to the technical field of sludge calorific value conditioning, in particular to a sludge calorific value conditioning machine. Background technique [0002] Sludge refers to the sediment, particulate matter and floating matter produced when wastewater is treated by physical methods, chemical methods, physical chemical methods and biological methods. Sludge generally refers to thick matter between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. The concentration of suspended matter is generally 1% to 10%. Below this concentration, it is often called mud; [0003] Before the sludge is burned in the furnace, it is necessary to ensure that the organic matter of the sludge is not lost, and the sludge is dehydrated to ensure that the sludge has sufficient calorific value to meet the requirements of the boiler for combustion fuel in the furnace; [0004] Traditional...

AI Technical Summary

Problems solved by technology

Among them, the natural drying method has a large drying efficiency, a large demand site, and high factors affected by natural conditions. The addition of polymer coagulant in the early stage of the granulation dehydration method will discharge high-concentration pollutant wastewater, and the post-treatment cost is high. From Economical and applicability considerations are not suitable for sludge drying

[0005] The mechanical dehydration method can be widely applied to the dehydration treatment before sludge incineration. The commonly used methods include plate and frame sludge dewatering, belt sludge dewatering and centrifugal sludge dewatering, etc., but all of them have the disadvantages of easy clogging, loud noise and vibration. The characteristics of severe and narrow application range of sludge treatment
