Problems solved by technology
The sludge discharged from the sewage treatment plant is generally a loose colloidal paste with a water content of about 80%. characteristics, so it is very unfavorable for drying treatment
[0003] Existing industrial waste and sludge are mostly treated by high-temperature incineration. In the existing sludge incineration technology, the sludge is transported to the combustion furnace through the sludge furnace delivery pipeline. Since the sludge generally contains Moisture, the sludge containing moisture is easy to form a bridge in the sludge feeding pipeline, so the existing sludge feeding pipeline has the phenomenon of sludge bridging blockage, which reduces the transmission efficiency and leads to sludge in the sludge bin. The sludge cannot be smoothly transported to the sludge dryer, which affects the sludge incineration effect and incineration efficiency

Embodiment
[0036] Such as Figure 1-5 As shown, a crushing device for preventing sludge clogging includes a screw conveyor 1 and a sludge dryer 2; a crushing device 3 is connected between the screw conveyor 1 and the sludge dryer 2; the crushing device 3 includes a shell body 31, a crushing and stirring chamber 32 is formed inside the shell 31; a stirring and crushing mechanism for crushing sludge is rotatably connected in the crushing and stirring chamber 32; A crushing device is installed between them, and the crushing device can fully crush the sludge, so that the volume of the sludge is reduced, preventing a large amount of agglomeration of the sludge, and avoiding the sludge that is wet or easily agglomerated at the inlet of the dryer. Easy to clog.
[0037] The invention solves the problem that the traditional sludge pipeline transportation will block the pipeline, and the feeding volume is large, continuous and uninterrupted feeding is possible, the feeding efficiency is improved, ...

The invention relates to crushing equipment for preventing sludge blockage. The crushing equipment comprises a spiral conveyor and a sludge dryer, wherein a crushing device is connected between the spiral conveyor and the sludge dryer; the crushing device comprises a housing, and a crushing and stirring cavity is formed in the housing; and a stirring and crushing mechanism for crushing sludge is rotatably connected in the crushing and stirring cavity. The crushing equipment is simple in structure and convenient and practical. By arranging the crushing device between the spiral conveyor and thesludge dryer, the crushing device crushes sludge fully, so that the volume of the sludge is decreased, the sludge is prevented from being agglomerated massively, and a condition of easy blockage of the sludge entering an inlet of the dryer when relatively humid or easily agglomerated sludge is conveyed is avoided.
Description
technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a crushing equipment for preventing sludge clogging. Background technique [0002] Sludge is a kind of viscous substance produced in the process of sewage treatment. It is mainly composed of aerobic and anaerobic microorganisms. Various complex mixtures of organic matter, metals, germs, insect eggs, colloids, etc. on the ground. The composition of sludge varies greatly and varies with the source of sewage, sewage treatment process and season. The sludge discharged from the sewage treatment plant is generally a loose colloidal paste with a water content of about 80%. characteristics, so it is very unfavorable for drying treatment. [0003] Existing industrial waste and sludge are mostly treated by high-temperature incineration. In the existing sludge incineration technology, the sludge is transported to the combustion furnace through the s...
