Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] see figure 1 , an integrated device for sludge dehydration and drying, comprising a box body 1, a distributor 3, a conveyor belt 2, an extrusion device and a hot air device.
[0027] The box 1 is a metal cavity similar to a cuboid, with a distributor 3 on the left side of the top, a hot air device on the right side of the top, an exhaust port 11 near the hot air device on the top, a drain port 12 on the left side of the bottom, and a water outlet 12 on the right side of the bottom. A mud outlet 13 is provided on the side.
[0028] The upper end of the cavity of the distributor 3 is provided with a feed inlet 31, and the lower end of the cavity is provided with a pre-filter outlet 32. The cross section of the cavity of the distributor 3 gradually becomes smaller from top to bottom. The cross-sectional shape is circular, and the cross-se...

The invention relates to a sludge dewatering and drying integrated device and a treatment method. The sludge dewatering and drying integrated device comprises a box body (1), a material distributing device (3), a conveying belt (2), an extruding device and a hot air device; the material distributing device is arranged on the right side of the top of the box body, and the hot air device is arrangedon the right side of the top of the box body; the conveying belt is arranged in the box body and comprises a filter cloth belt and a cloth belt wheel set, and under rotating of the cloth belt wheel set, the filter cloth belt moves cyclically from left to right; the left part of the conveying belt faces an outlet of the material distributing device, the right part of the conveying belt faces an air outlet of the hot air device, the conveying belt is provided with the extruding device in the stroke of the upper-layer filter cloth belt from left to right, and the filter cloth belt penetrates through the extruding device; and an exhaust opening (11) is formed in the top of the box body, a drainage opening (12) is formed in the left side of the bottom of the box body, and a sludge dischargingopening (13) is formed in the right side of the bottom of the box body. Sludge is dewatered and dried in the same device, the sludge dewatering and drying integrated device is concise in structure andreliable in operation, and energy consumption is lowered.
Description
technical field [0001] The invention relates to sludge dehydration and drying treatment, in particular to an integrated device for sludge dehydration and drying and a treatment method. Background technique [0002] Sludge treatment is a process of reducing, stabilizing and harmless sludge such as concentration, conditioning, dehydration, stabilization, drying or incineration. After purification, industrial and domestic wastewater produces a large amount of sludge with a water content of 97% to 99.7%. After conventional pre-dehydration treatment, the water content is still relatively high, generally 80% to 85%. According to investigations and research, nearly 90% of the sludge produced by wastewater treatment stations and sewage treatment plants has not been properly reduced and resourced. Pollution to soil and groundwater environment. Therefore, it is necessary to further effectively dehydrate and dry the sludge. [0003] At present, the sludge dehydration and drying equi...
