Description
Technical field
The utility model relates to a kind of resiliency compressible press filtration sheet frame device.
Background technology
Along with the popularizing of sewage treatment facility, the raising of handling rate and the in-depth of degree of treatment, the mud generation of Sewage Plant will have bigger growth, and the secondary pollution problem that causes thus can not be ignored.Therefore how reasonably handle, disposing sludge, become the problem that municipal wastewater treatment plant and relevant departments must draw attention.Both at home and abroad Treatment of Sludge is a lot of with the method for disposal, and general the employing concentrates, digestion, dehydration, mummification, effectively utilizes (mostly being agricultural), landfill and burning etc., or makes up disposal with SOME METHODS wherein.Should, to the processing and the disposal of sewage plant sludge, we compare with advanced country, and gap is bigger.The mud of municipal wastewater treatment plant is meant solid-state, the semisolid and the liquid discarded object of disposing of sewage and being produced, and contains a large amount of organic matters, heavy metal and pathogenic bacteria and pathogen etc., does not add and handles discharging arbitrarily, can cause serious pollution to environment.Total requirement is stabilisation, innoxious and minimizing to Treatment of Sludge.The mud that Sewage Plant produces contains a large amount of moisture, so, as mud is handled, at first just need carry out processed to mud.Traditional sludge dewatering technology and equipment is as mud plate and frame filter press, mud centrifuge, mud belt filter press, sludge vacuum dewaterer etc.Because the characteristic of municipal sludge, above-mentioned device for dehydrating sladge waste to the processed effect of mud generally at the 75-85% moisture content.Mud is in the colloid shape, for its follow-up drying and other treatment has been brought great difficulty and investment cost between the 60%-85% moisture content time.So, if can adopt less expensive, easy mud further to dewater to below 60% being the difficult problem that present municipal sludge is disposed, problem that presses for solution in the time of also with 80% left and right sides moisture content.
The volume in the press filtration chamber of traditional plate and frame filter press is fixed, and its press filtration pressure is that the discharge pressure by the mud delivery pump decides, generally at 0.6-1.6MPA.Effect diaphragm type sheet frame preferably is after mud is carried press filtration the secondary press filtration to be carried out by air diaphragms in the press filtration chamber, because the displacement of barrier film is little, compressed-air actuated pressure is also few with the pressure differential of sludge pump.So its dehydrating effect is also undesirable.
Summary of the invention
Because the problems referred to above that prior art exists the utility model proposes a kind of resiliency compressible press filtration sheet frame device, it can effectively address the above problem.
The utility model has adopted following technical scheme:
A kind of resiliency compressible press filtration sheet frame device, comprise some press filtration plates that have a sludge inlet and pierce into charging aperture and wrap the filter cloth of press filtration plate, the both sides of each press filtration plate or a side are equipped with the compression frame of a hollow design by mounting groove, and hollow lumen of this compression frame links to each other with the blowing plant of outside by a compressed air piping.
As further feature of the present utility model, round, the semi-circular or square that is shaped as hollow of elastic compression frame.
As further feature of the present utility model, the compression frame on the same press filtration plate is connected with blowing plant by same compressed air piping.
As further feature of the present utility model, compression frame material is flexible rubber.
As further feature of the present utility model, the material of press filtration plate is polypropylene material or metallic plate.
Owing to just used technique scheme, resiliency compressible press filtration sheet frame of the present utility model is simple, convenient, has solved that traditional filter press pressure is low, the shortcoming of costs and poor dehydration results, and more economical.

The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model:
According to shown in Figure 1, a kind of resiliency compressible press filtration sheet frame device, comprise some press filtration plate 1 and filter clothes 5 that have sludge inlet 4 at the middle part, per two blocks of filter clothes 5 enter and wrap up press filtration plate 1 from a charging aperture 4, the both sides of each press filtration plate 1 or a side are installed the compression frame 2 of a hollow design by mounting groove, when some press filtration plates 1 are used in combination, compression frame 2 is all installed in the both sides of middle press filtration plate 1, the press filtration plate 1 at two ends is equipped with compression frame 2 in that side towards the press filtration plate 1 of centre, and hollow lumen of this compression frame 2 links to each other with the blowing plant of outside by a compressed air piping 6.
In the present embodiment, the shape and the press filtration plate 1 of compression frame 2 are complementary, and the shape of elastic compression frame is generally round, the semi-circular or square of hollow; Compression frame 2 materials are flexible rubber or other elastomeric material; Compression frame 2 on the same press filtration plate 1 is connected with blowing plant by same compressed air piping 6; The material of press filtration plate 1 is polypropylene material or metallic plate; The pressure that bears in the sludge press filtration chamber 3 that two press filtration plates 1 are combined to form is not more than 40 kilograms.
When the beginning press filtration, compressed air is by being installed in the cavity 2 that press filtration plate 1 interior compressed air piping 6 enters hollow compression frame, and press filtration plate 1 closes up, and utilizes compression frame 2 and the press filtration plate 1 heaved to form sludge press filtration chamber 3.Mud is pressed into sludge press filtration chamber 3 by the mud delivery pump by sludge inlet 4 and the same press filtration principle of conventional panels frame is carried out filter-press dehydration to the mud in the press filtration cavity 3.Equipment is after finishing a press filtration, and the moisture content of the mud in the press filtration cavity 3 should be about 80%.
After finishing press filtration for the first time, the hydraulic system of equipment is started working, hydraulic stem is by carrying out the secondary high-pressure extruding to sheet frame, air in the compression frame 2 is when receiving high-pressure extrusion, gas bleeder valve on the compressed air piping 6 is opened, the air of compression in the frame 2 is forced out, and the space in sludge press filtration chamber 6 is by second-compressed, by the mud after the press filtration first further by filter-press dehydration.Cavity volume further is compressed to below 50%.Moisture percentage in sewage sludge after the secondary press filtration reaches below 60%.
Equipment is after finishing secondary extrusion, and is the same with traditional plate compression, begins to enter the dump flow process.After dump is finished, enter next press filtration circulation according to above-mentioned flow process.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
