Abstract
A pressure filter charge -in system, including pressure filter charge pump, sludge impoundment and pressure filter, the export of sludge impoundment is connected to the inlet pipe of pressure filter charge pump, and the entrance point of pressure filter is connected to the discharging pipe, the discharging pipe of pressure filter charge pump still is equipped with a bypass, set up a relief valve in the bypass, the entry of the pressure release exit linkage earial drainage pipe of relief valve, the export of earial drainage pipe with person in charge's entry linkage of mud stirred tubular net. The utility model has the advantages of: through setting up the relief valve, the space that the feed liquid that surpasss pressure was opened through the relief valve emits into the mud stirred tubular net of sludge impoundment, carries out make full use of to the energy of pressure release mud, can realize good dewatering effect, the disinvestment, through setting up the flocculating agent pipe, avoid disposing alone the flocculation plant, the equipment of reducible flocculation in -process drops into and power consumption input.
Description
Technical field
The utility model relates to field of sewage treatment equipment, is specifically related to a kind of filter press feed system.
Background technology
In sewage disposal, plate and frame filter press is the common equipment of the waste residue in filtering sewage, and carry the sewage of waste residue secretly after the boosting of filter press feed pump, send into plate and frame filter press, water is by discharging after filter cloth, and filter residue is stayed on filter cloth.In pressure-filtering process, filter residue is cumulative on filter cloth.Sewage is increasing by the resistance of plate and frame filter press, and drainage amount is fewer and feweri, and press filtration feed pump outlet pressure is suppressed larger and larger, easily damages filter press feed pump.
In addition, in prior art, in the flocculation process of mud, need to configure flocculation plant separately, carry out flocculation stirring with mixer, manually have high input, cost is high.
Summary of the invention
Goal of the invention: for the deficiency of currently available technology, provides a kind of drainage effective, the filter press feed system of protection filter press feed pump.
Technical scheme: a kind of filter press feed system described in the utility model, comprise filter press feed pump, sludge-tank and filter press, the feed pipe of described filter press feed pump connects the outlet of sludge-tank, discharge nozzle connects the entrance point of filter press, the discharge nozzle of described filter press feed pump is also provided with a bypass, described bypass is arranged a relief valve, the pressure relief vent of described relief valve connects the entrance of leak-off pipe, and the outlet of described leak-off pipe is connected with supervisor's entrance of described sludge agitation pipe network.
Further, described sludge-tank top arranges a flocculant pipe, and the bottom of described flocculant pipe is higher than the liquid level of sludge-tank.
Beneficial effect: compared with prior art, the utility model has the advantage of: by arranging relief valve, the feed liquid exceeding pressure enters the sludge agitation pipe network of sludge-tank by the space that relief valve is opened, the energy of pressure release mud is made full use of, good dehydrating effect can be realized, reduce investment; By arranging flocculant pipe, avoiding configuring flocculation plant separately, the equipment investment in flocculation process and power consumption input can be reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by accompanying drawing, technical solutions of the utility model are described in detail.
embodiment 1:as shown in Figure 1, a kind of filter press feed system described in the utility model, comprise filter press feed pump 1, sludge-tank 2 and filter press 3, the feed pipe 4 of described filter press feed pump 1 connects the outlet of sludge-tank 2, discharge nozzle 5 connects the entrance point of filter press 3, the discharge nozzle 5 of described filter press feed pump 1 is also provided with a bypass, described bypass is arranged a relief valve 6, the pressure relief vent of described relief valve 6 connects the entrance of leak-off pipe 6, and the outlet of described leak-off pipe 7 is connected with supervisor's entrance of described sludge agitation pipe network 8.
Described sludge-tank top arranges a flocculant pipe 9, and the bottom of described flocculant pipe 9 is higher than the liquid level of sludge-tank 2.
The operation principle of a kind of filter press feed system described in the utility model is: carry the mud of waste residue secretly after filter press feed pump 1 boosts, enter filter press 3, water is by discharging after filter cloth, filter residue is stayed on filter cloth, when filter press feed pump 1 pressure meets setting pressure, filter press feed pump 1 continues the work of charging pressurize constant voltage, the space that the feed liquid exceeding pressure is opened by relief valve 6 is discharged through leak-off pipe 7, the muddy water mixed solution of discharging possesses high-lift momentum, the mud of earial drainage enters the sludge agitation pipe network 8 bottom sludge-tank, carry out cloth mud, sludge-tank 2 is stirred, directly flocculant is added by the flocculant pipe 8 at sludge-tank 2 top, mixing of flocculant and mud can be realized, after 1 press filtration operation, the mixing of sludge-tank 2 mud can be ensured completely.By adding relief valve 6, leak-off pipe 7, can ensure that filter press feed system normally works, this kind of mode can make full use of the energy of pressure release mud, realize good dehydrating effect, reducing investment, by adding flocculant pipe 9, the equipment investment in flocculation process and power consumption input can be reduced.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
