Abstract
The utility model discloses a filter pressing system for sewage treatment of chemical fiber enterprises. The filter pressing system comprises a sewage pool, a filter press and an intermediate tank; the sewage pool is connected with the intermediate tank through a first pipeline; the first pipeline is provided with a delivery pump; a second pipeline is arranged between the intermediate tank and the filter press and is provided with a filter pump and a pressure sensor, a signal of the pressure sensor is input to a PID (Proportion Integration Differentiation) regulating instrument, and the output end of the PID regulating instrument is electrically connected with a motor of the filter pump through a frequency converter; and the second pipeline is shorter than the first pipeline. Compared with the prior art, the filter pressing system has the advantages that the filter pressing system is additionally provided with the intermediate tank, the intermediate tank can be arranged at a position closer to the filter press, and the distance from the intermediate tank to the filter press is far smaller than the distance from the sewage pool to the filter press in the prior art, so that the pressure regulation is more sensitive, the pressure at the inlet of the filter press can be effectively matched with an actual working state, and the work efficiency of the filter pressing system is increased.
Description
Technical field
The utility model relates to a kind of chemical fiber factory sewage disposal system, the press filteration system that especially a kind of chemical fiber factory sewage disposal is used.
Background technology
Along with the progress of society, chemical fibre industry has had larger development, and the processing problem of chemical fibre sewage also is taken seriously day by day; This has higher requirement to sewage disposal system, and sewage disposal system also needs constantly improvement to adapt to new Times ' Demand.
Chinese patent " feeding device of filter press (200920313283.X) " discloses a kind of press filteration system, it comprises cesspool and filter press, cesspool and filter press pass through pipeline communication, side at the close cesspool of pipeline is provided with delivery pump, and be provided with pressure sensor and delivery pump at pipeline and form Closed-loop pressure control, the problem that filter press and delivery pump is exerted an influence to solve pipeline upward pressure shakiness.This patented technology is better than conventional art, but have a drawback: namely conveyance conduit is longer, pressure is regulated to exist inevitably and is lagged behind, so that the pressure of filter press import department still can not match with actual working state effectively, therefore is necessary existing press filteration system is improved.
Summary of the invention
The purpose of this utility model is that a kind of pressure that designs for the deficiency that solves above-mentioned technology is regulated the press filteration system that more sensitive chemical fiber factory sewage disposal is used.
The press filteration system that the designed chemical fiber factory sewage disposal of the utility model is used comprises cesspool and filter press, also comprises pans, and described cesspool connects pans by the first pipeline; The first pipeline is provided with delivery pump; Be provided with second pipe between described pans and the filter press, be provided with filter pressing pump and pressure sensor at second pipe, the signal of described pressure sensor is input to a PID adjusting apparatus, and the output of this PID adjusting apparatus is electrically connected with the motor of described filter pressing pump by a frequency converter; Described second pipe length is less than the first pipeline.Wherein delivery pump is used for sewage is delivered to pans from cesspool, and filter pressing pump is used for sewage is delivered to filter press from pans.
As preferably:
Described pans are provided with liquid level sensor, and the signal of described liquid level sensor is input to a PLC controller, and the output of this PLC controller is electrically connected with the motor of described delivery pump;
Described second pipe length is 3 meters to 5 meters;
The press filteration system that the designed chemical fiber factory sewage disposal of the utility model is used, be provided with pans than prior art more, and pans can be arranged on the position nearer with filter press, second pipe is used for connecting filter press and pans, be provided with a PID regulating system the same with prior art at second pipe, because the distance between pans and the filter press is less than the distance of cesspool in the prior art and filter press, therefore pressure is regulated more sensitive, so that the pressure energy of filter press import department matches with actual working state effectively, improve its operating efficiency.
