Abstract
The utility model discloses a filter press device for treating biochemical sludge, which comprises a filter press pot, a filter press and a waste residue tank, wherein the filter press is respectively connected with the filter press pot and the waste residue tank by pipes, a feeding pump is connected between the filter press and the waste residue tank, a filter press valve is connected between the filter press and the filter press, and the filter press pot is provided with a compressed air pipe. The filter press device for treating biochemical sludge uses compressed air as power, has high filter pressure, saves power, and has low maintenance cost and high filter press efficiency.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, specifically, is a kind of filter-pressing device that is used to handle biochemical sludge.
Background technology
The power of pump as press filtration is adopted in traditional filter press charging, is made by the medium of press filtration by pump to produce pressure, thereby the pressure medium in plate and frame type filter-press is raise, and liquid is by filter cloth, and solid particle then is left in the filter chamber.Handle biochemical sludge with such filter press and exist following problem: biochemical sludge is thickness very, is directly carried toward filter press by pump, and gear pump, the screw pump cycle of operation are very short, centrifugal pump energy consumption height.Thickness medium often cause pipeline and in-line filter to stop up and the damage of feed pump, maintenance cost is high.In sum, the major defect of the filter press of the biochemical sludge that traditional concentration is higher is that press filtration is discontinuous, and the feed pump fault rate is high, and maintenance cost is high, and press filtration efficient is low, and energy consumption is higher.
The utility model content
The utility model has overcome above-mentioned shortcoming, has proposed a kind of filter-pressing device that is used to handle biochemical sludge.
The technical scheme in the invention for solving the technical problem is:
A kind of filter-pressing device that is used to handle biochemical sludge, it comprises pressure-filtering tank, filter press and waste residue pond, filter press links to each other with pressure-filtering tank, waste residue pond respectively by pipeline; Between filter press and waste residue pond, be connected to feed pump; Between filter press and pressure-filtering tank, be connected to the press filtration valve; Be connected to compressed air piping on the pressure-filtering tank.Compressed air can enter in the pressure-filtering tank by this pipeline.
Be connected to atmospheric valve on the described pressure-filtering tank.Be connected to overflow valve on the described pressure-filtering tank.
Be provided with outlet valve between filter press and the feed pump.
Agitator is equipped with in described waste residue pond.Like this, the material of before press filtration need being handled stirs, and dilutes preliminary treatment, further improves the treatment effect to biological sludge of the present utility model.
The utility model adds pressure-filtering tank by biochemical sludge is suitably diluted, and carries out press filtration with compressed air, press filtration efficient can be improved 75%, reduces maintenance cost greatly.
Advantage of the present utility model is: as power, press filtration pressure height is saved power with compressed air, and maintenance cost is low, press filtration efficient height.

The specific embodiment
As shown in Figure 1, filter-pressing device of the present utility model comprises pressure-filtering tank 2, filter press 3 and waste residue pond 4, and filter press 3 links to each other with pressure-filtering tank 2, waste residue pond 4 respectively by pipeline; Between filter press 3 and waste residue pond 4, be connected to feed pump 5; Between filter press 3 and pressure-filtering tank 2, be connected to press filtration valve 7; Be connected to compressed air piping 1 on the pressure-filtering tank 2.
Be connected to atmospheric valve 8 and overflow valve 9 on the above-mentioned pressure-filtering tank 2.Be provided with outlet valve 10 between filter press 3 and the feed pump 5.Agitator 6 is equipped with in waste residue pond 4.
Before filter press 3 work, at first in waste residue pond 4, put into an amount of biochemical sludge, add the biochemical waste water of handling well, drive agitator 6 and stir back (solid content is about 10%), stop agitator 6.The action of filter press 3 closing plates is to having closed compacting fully.Open the gateway valve of the feed pump 5 of filter press 3, open feed pump 5,4 toward filter press 3 interior feed from the waste residue pond.Open the atmospheric valve 8 and the press filtration valve 7 of pressure-filtering tank 2 simultaneously, toward pressure-filtering tank 2 interior feed, until overflow valve 9 overflows, the overflow valve 9 of occlusion pressure filter tank 2 and the outlet valve 10 of feed pump 5 stop filter press feed pump 5.Being blown into pressure from compressed air piping 1 is that the compressed air of 0.65MPa carries out press filtration, stops water outlet or gives vent to anger until the delivery port of filter press 3.If water outlet, expression press filtration work finishes shut-down operation.If give vent to anger, repeat aforesaid operations till the interior filter cake compacting of filter press 3 filter chambers.
More than the filter-pressing device that is used to handle biochemical sludge provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
