Description
Technical field
The invention belongs to sewage lagoon loading techniques field, specifically, relate to a kind of chemicals dosing plant.
Background technology
Sewage Plant is provided with between dosing, and present stage dephosphorization mainly uses volume pump, acid proof pump to join aeration tank end by pipeline after being diluted by bodied ferric sulfate between dosing, reaches the object of dephosphorization after chemical precipitating and flocculation.But due to the bodied ferric sulfate problem such as crystallization and bonding in the duct, easily cause line clogging, have a strong impact on treatment effect and the efficiency of sewage, this is because dosage is less, pipe flow speed is low, and bodied ferric sulfate very easily crystallization occurs.Sewage Plant repeatedly occurs because bodied ferric sulfate crystallization causes line clogging, even booster.In chemical dephosphorization, the dosage of bodied ferric sulfate directly affects the phosphor-removing effect of water treatment, manually adds and cannot do real-time adjustment according to water quality and quantity to bodied ferric sulfate dosage, can not reach desirable phosphor-removing effect.
Prior art is not enough: dosage is little, and flow velocity is low, the easy Crystallization Plugging pipeline of bodied ferric sulfate, even booster.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of chemicals dosing plant, can certain flow velocity be kept, lasting to aeration tank dosing, and timing is rinsed, bodied ferric sulfate not easily crystallization in pipe, not easily causes line clogging, improves efficacy of drug administration.
The present invention seeks to realize like this: a kind of chemicals dosing plant, its key is: comprise inverted U siphon pipe, ball float and support, described support comprises longitudinal rod and at least one piece of transverse plate, the equal permanent sleeve in middle part of described transverse plate is located on described longitudinal rod, the end, two ends of described transverse plate is equipped with chute, siphonal two longitudinal pipes of described inverted U are passed down through described chute respectively, the siphonal longitudinal pipe of this inverted U is longer than another longitudinal pipe, and the end winding support of the longitudinal pipe that this inverted U siphon pipe is short has described ball float.
This constructional device is arranged on dosing pond, longitudinal rod is vertically fixed on the sidewall in dosing pond, the short longitudinal pipe of inverted U siphon pipe stretches in dosing pond, ball float floats over the liquid liquid level in dosing pond, the longitudinal pipe of inverted U siphon pipe range is positioned at outside dosing pond, to aeration tank dosing, during use, after filling up water or liquid in siphon pipe, siphon pipe just start to continue to dosing in aeration tank, ball float moves along with dosing pond liquid level, inverted U siphon pipe synchronously slides up and down, pipe inner liquid medicine is made to be in flow state all the time, not easily crystallization, not easily cause line clogging, improve efficacy of drug administration.
Above-mentioned chute is symmetrical arranged, and the edge of this chute is evenly provided with a circle roller.
Adopt said structure, inverted U siphon pipe tube wall and roller contact, directly do not contact chute, reduces sliding resistance.
The side-wall hole of the longitudinal pipe that above-mentioned inverted U siphon pipe is short is communicated with washpipe, and this washpipe is near ball float and be positioned at above ball float, and the longitudinal pipe that described inverted U siphon pipe is short is also provided with V-type ball valve, and this V-type ball valve is between described washpipe and ball float.
Adopt said structure, washpipe connects running water pipe, washpipe can fill up water by inverted U siphon pipe before dosing, start inverted U siphonal siphon, start dosing, and can not timing siphon pipe is rinsed, reduce further the possibility of liquid at pipe intercrystalline, when V-type ball valve can prevent washpipe from washing by water in pipe, water liquid is washed by water in dosing pond, can also regulate the flow of inverted U siphon pipe herb liquid.
The middle part of above-mentioned transverse plate is vertically provided with fixed muffle, and the sidewall of this fixed muffle is provided with standing bolt, and described longitudinal rod is located in described fixed muffle and is fastened by standing bolt.
Adopt said structure, fixed sleeving improves the stability that transverse plate is connected with longitudinal rod, and is fastened by bolt, is convenient to the dismounting maintenance of support.
Above-mentioned inverted U siphon pipe is made up of copper pipe, and the longitudinal pipe lower end kink of this inverted U siphon pipe range has guide thimble.
Adopt said structure, the inverted U siphon pipe be made up of PVC, because pvc pipe is yielding under the effect of bodied ferric sulfate, can cause pvc pipe to bend, and the upper and lower slip of inverted U siphon pipe is obstructed; The inverted U siphon pipe be made up of glass is frangible; The inverted U siphon pipe quality be made up of copper pipe is hard, not easily corrosion-deformation, and therefore inverted U siphon pipe of the present invention is selected to be made up of copper pipe.
Beneficial effect: the present invention is a kind of chemicals dosing plant, can keep certain flow velocity, continue incessantly to aeration tank dosing, and can to timing flushing arrangement, and bodied ferric sulfate not easily crystallization in pipe, not easily causes line clogging, improve efficacy of drug administration.
