Utility model content
The purpose of this utility model is to provide a kind of mud supercharging dewater unit, and the moisture percentage in sewage sludge after dehydration can be made to reduce further, easily come off, not easily stick on filter cloth, and filter cloth is long for service time, replacement frequency is low, and then reduces Treatment of Sludge cost.
In order to achieve the above object, the utility model provides a kind of mud supercharging dewater unit, comprise membrane filter plate, filter cloth and air compressor machine, the both sides of membrane filter plate are located at by filter cloth, membrane filter plate is provided with charging hole, air admission hole and osculum, described charging hole, the two sides of all through membrane filter plate of air admission hole and osculum, the two sides concave shaped of membrane filter plate is in depression district, described membrane filter plate is several piece, several piece membrane filter plate is set up in parallel, depressed area between adjacent two pieces of membrane filter plates surrounds the worry chamber of a relative closure, described charging hole is communicated with described worry chamber, closed diaphragm cavity is provided with in described membrane filter plate, described membrane filter plate side is provided with opening, described opening is communicated with described diaphragm cavity, the air admission hole be located on the membrane filter plate in outside is communicated with described air compressor machine by pipeline.
In an embodiment, described pipeline is provided with pressure-regulating device.
In an embodiment, described pipeline is provided with pressure detecting instrument.
In an embodiment, described charging hole is located at the centre of described membrane filter plate.
In an embodiment, described air admission hole is located at the top of described membrane filter plate.
In an embodiment, described osculum is located at the bottom of described membrane filter plate.
Compared with prior art, the beneficial effect of the technical program is: the utility model mud supercharging dewater unit, because membrane filter plate is provided with air admission hole, the two sides of the through membrane filter plate of air admission hole, and air admission hole is communicated with air compressor machine by pipeline, producing gases at high pressure by air compressor machine passes in air admission hole through pipeline, and then lead between filter cloth and mud, further squeezing mud, the moisture content of mud is made to reduce about 5% further, and gases at high pressure blow the mud adhered on filter cloth open, thus mud is easy to come off from filter cloth, and then filter cloth is not easily made dirty, can use for a long time, the frequency changing filter cloth reduces greatly, within 1 year, only need replacing filter cloth, thus greatly reduce the cost of Treatment of Sludge.

Fig. 1 is the cross-sectional view of the utility model mud supercharging dewater unit.
Fig. 2 is the structural representation of the membrane filter plate of the utility model mud supercharging dewater unit.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, clear, complete description is carried out to the technical solution of the utility model.
Refer to shown in Fig. 1 and Fig. 2, the utility model provides a kind of mud supercharging dewater unit, comprises membrane filter plate 1, filter cloth 2 and air compressor machine 3.The both sides of membrane filter plate 1 are located at by filter cloth 2.Membrane filter plate 1 is provided with charging hole 11, air admission hole 12 and osculum 13, the two sides of all through membrane filter plate 1 of described charging hole 11, air admission hole 12 and osculum 13.The two sides concave shaped of membrane filter plate 1 is in depression district 101.Described membrane filter plate 1 is several piece, and several piece membrane filter plate 1 is set up in parallel, and the depressed area 101 between adjacent two pieces of membrane filter plates 1 surrounds the worry chamber 102 of a relative closure.Described charging hole 11 is communicated with described worry chamber 102, thus mud can pass into worry chamber 102 from charging hole 11.Closed diaphragm cavity 103 is provided with in described membrane filter plate 1, described membrane filter plate 1 side is provided with opening 14, described opening 14 is communicated with described diaphragm cavity 103, during squeezing mud, extraneous from this opening 14 toward water filling or inflation in diaphragm cavity 103, make the two sides of membrane filter plate 1 outwards expand to extrude the mud of considering in chamber 102, dewater.The air admission hole 12 be located on the membrane filter plate 1 in outside is communicated with described air compressor machine 3 by pipeline 4, producing gases at high pressure by air compressor machine 3 passes in air admission hole 12 through pipeline 4, and then gases at high pressure lead between filter cloth 2 and mud, further squeezing mud, gases at high pressure are separated the mud adhered on filter cloth 2 and filter cloth 2 air-dry mud, thus mud is easy to come off from filter cloth 2, and the moisture content of mud reduces about 5% further.
Described pipeline 4 is provided with pressure-regulating device 5, for regulating the pressure of the gas passing into pipeline 4.Described pipeline 4 is provided with pressure detecting instrument 6, for detecting the gas pressure passed in pipeline 4.
