A kind of device for dehydrating sladge waste
The utility model relates to sewage treatment area, specifically refers to a kind of device for dehydrating sladge waste.
The reinforcement of Along with people's environmental consciousness, a large amount of sewage works builds up successively in each big and medium-sized cities and puts into operation, and wastewater treatment in China market will welcome the epoch of develop rapidly.Every day will be discharged the hundreds of even up to ten thousand tons of the excess sludge of water ratio about 99.2% by each sewage work, simultaneously, the sludge treatment expense account for sewage work whole working costs 20～50%.The mud of Sewage Plant is a kind of uneven, complicated dispersed system, and its water ratio is high, and volume and quantity are huge, is prone to smellyly, therefore must in time handle, and the sludge treatment decrement of at first should dewatering is so that the subsequent disposal disposal.In the existing device for dehydrating sladge waste, all there are shortcomings such as complex equipments, investment is big, energy consumption is high, dehydration rate is low, therefore, research and develop a kind of advantages of simplicity and high efficiency device for dehydrating sladge waste and seem very important.
The utility model content
For solving shortcomings such as existing device for dehydrating sladge waste cost is high, energy consumption is big, dehydration rate is low, the utility model provide a kind of simple in structure, energy consumption is low, the device for dehydrating sladge waste that dehydration rate is high.
The utility model adopts following technical scheme: a kind of device for dehydrating sladge waste; Include hopper, compression set, extrusion piston, dewatering container; Said dewatering container upper end is connected with material bin through pipeline, is provided with extrusion piston on said dewatering container inner chamber top, and the bottom is fixed with filter cylinder; The inner chamber of said filter cylinder is communicated with the dewatering container inner chamber, and the inwall of its outer wall and dewatering container forms the dehydration chamber of sealing; Be provided with rising pipe in said dewatering container bottom; Said extrusion piston one end side surface contacts with said dewatering container inwall, and the other end is connected with said compression set.
Said compression set is a screw block, and the one of which end fixedly installs, and the other end is connected with said extrusion piston one end.
Described rising pipe is connected with receiving flask, and said receiving flask is communicated with vacuum pump.
Described filter cylinder is combined by two cylinder and fiber filter cloths that have even sieve aperture, and said fiber filter cloth is clipped in the middle of two cylinders that have an even sieve aperture.
The base plate of described dewatering container is for can unload bottom.Said dewatering container and material bin junction are provided with valve.
During sludge dewatering, mud is placed material bin, open valve, make mud be full of dewatering container, valve-off.The rocking bar of operation screw block; Screw block one end withstands the top board that fixedly installs, and the other end connects extrusion piston to pressing down, the be squeezed extruding of piston of mud; Under squeezing action power; Water in the mud flows into the dehydration chamber through filter cylinder, gets into receiving flask through outlet conduit, realizes the high-efficiency dehydration and the mummification of mud.The open vacuum pump makes whole system be in negative pressure state simultaneously, is provided with seal cartridge at extrusion piston and junction, dewatering container top; Guarantee the sealing in the compression container, mud is squeezed under the double reaction plus with vacuum take-off, has improved dehydration rate greatly; Water in the mud flows out through filter cylinder and gets into receiving flask, after the dehydration, closes vacuum pump; Open the unloaded bottom of dewatering container, the mud after the dehydration is discharged.
From the above mentioned, the related device for dehydrating sladge waste of the utility model is simple in structure, less energy-consumption, dehydration rate are high, can be widely used in the industrial production.

Label among the figure: 1-material bin, 2-mud, 3-top board, 4-rocking bar, 5-screw block, 6-seal cartridge; 7-extrusion piston, 8-valve, 9-filter cylinder, 10-dewatering container, the 11-chamber of dewatering, 12-can unload bottom; The 13-rising pipe, 14-receiving flask, 15-vacuum pump, 16-cylinder, 17-fiber filter cloth.
Below in conjunction with accompanying drawing the utility model is described further.
With reference to figure 1: a kind of device for dehydrating sladge waste, include hopper 1, screw block 5, extrusion piston 7, dewatering container 10, dewatering container 10 upper ends have the material bin inlet; Material bin 1 is provided with valve 8 with dewatering container 10 junctions, regulates mud 2 and gets into dewatering container 10 in batches, and extrusion piston 7 is arranged in the dewatering container 10; Can slide along dewatering container 10 inwalls; Screw block 5 one ends are top board 3 fixedly, and the other end is arranged on the extrusion piston 7, and the bottom is provided with filter cylinder 9 in the dewatering container 10; Form dehydration chamber 11 between filter cylinder 9 outer walls and dewatering container 10 inwalls, dewatering container 10 bottoms have outlet conduit 13.Rising pipe 13 is outside equipped with receiving flask 14, vacuum pump 15, and receiving flask 14 1 outlets are communicated with rising pipe 13, and receiving flask 14 another outlets are communicated with vacuum pump 15.Be provided with in dewatering container 10 bottoms and can unload bottom 12, supply the mud after the dehydration to discharge.
During mud 2 dehydrations, mud 2 is placed material bin 1, open valve 8, make mud 2 be full of dewatering container 10, valve-off 8.Top board 3 is fixing, withstands screw block 5, and rocking bar 4 is fluctuated, and extrusion piston 7 is to pressing down, the be squeezed squeezing action of piston 7 of mud 2.Under squeezing action power, the water in the mud 2 flows into dehydration chamber 11 through filter cylinder 9, gets into receiving flask 14 through rising pipe 13, realizes the high-efficiency dehydration and the mummification of mud 2.Simultaneously the open vacuum pump 15, make whole system be in negative pressure state, and extrusion piston 7 is provided with movable sealing sleeve 6 with dewatering container 10 junctions, the guarantee system sealing, and mud 2 is squeezed under the double reaction plus with vacuum take-off, has improved dehydration rate greatly.
In conjunction with referring to Fig. 2, filter cylinder 9 is combined with fiber filter cloths 17 by two cylinders 16 that have even sieve aperture, and fiber filter cloth 17 is sandwiched in the middle of two cylinders 16 that have an even sieve aperture, and fiber filter cloth 17 keeps stationary states when realizing sludge dewatering.
