Abstract

The utility model relates to a non-block chemical feeding device in the treatment of industrial waste water, which solves the problem that the impurities in lime cream blocks a solenoid valve, thus causing inspection by stopping production. The non-block chemical feeding device in the treatment of industrial waste water comprises a lime dissolving tank, an inlet pipe, a reacting tank, a pH meter, a pH display and a solenoid valve controller; the inlet pipe is arranged at the upper part of the lime dissolving tank, the pH meter and an agitation mechanism are arranged in the reacting tank, a discharging pipe is arranged at one side of the middle part of the lime dissolving tank, the outlet of the discharging pipe is arranged at the upper part of the reacting tank; the solenoid valve is arranged on the inlet pipe and is communicated with the pH meter by pipelines, the pH display and the solenoid valve controller are arranged on the pipeline which is used for communicating the solenoid valve and the pH meter. The non-block chemical feeding device can not block a dosing pump and the solenoid valve and medicines can not overflow, thus being capable of realizing continuous dosing, reducing ordinary maintaining cost and ensuring the stability and continuality of the follow-up operation.

Description

Industrial Wastewater Treatment does not have the obstruction chemicals dosing plant

Technical field

The utility model relates to the chemicals dosing plant of Industrial Wastewater Treatment.

Background technology

Most of technology of Treatment of Industrial Water engineering is to throw in various medicaments according to former aqueous nature and process object, remove harmful and hard-degraded substance through physics (machinery), chemical action, make follow-up biochemical treatment effluent characteristics can reach relevant national standard or satisfy processing requirement.Therefore, medicine system is a composition link the most basic in the engineering of water treatment pretreatment system, tool typical meaning such as pH control during wherein especially with acid-base neutralisation process pH control, flocculation agent flocculation.In the process of regulating sewage pH value, especially extensive to add milk of lime, cheap and easy to get because of it, but water-fast impurity is more in the lime, often stops up volume pump and valve.Power adds milk of lime and often adopts volume pump, makes very easy the breaking of barrier film of volume pump after the obstruction.In addition, milk of lime also easily in the crystallization of metering pump liquid end, causes the import and export non-return valve of liquid end and valve seat to fit, and has had a strong impact on the normal operation of volume pump and sewage disposal.When gravity adds milk of lime, what of magnetic valve and pH meter control milk of lime dosage utilization have, because impurity and milk of lime easily stop up magnetic valve, frequent stop production to overhaul, influenced the effect that adds continuously and flocculate of milk of lime, the normal operation of follow-up sewage disposal has been produced very big influence.

Summary of the invention

Impurity stops up magnetic valve in the milk of lime in order to solve, and the problem of frequent stop production to overhaul, and the utility model provides a kind of Industrial Wastewater Treatment not have the obstruction chemicals dosing plant.

The technical solution that realizes above-mentioned purpose is as follows:

Industrial Wastewater Treatment does not have the chemicals dosing plant of obstruction and comprises lime dissolving tank, water inlet pipe, reactive tank, pH meter and pH indicating meter and solenoid valve controller, water inlet pipe is located at lime dissolving tank top, be provided with pH meter and stirring mechanism in the reactive tank, lime dissolving tank middle part one side is provided with discharge nozzle, and the outlet of discharge nozzle is positioned at reactive tank top;

Water inlet pipe is provided with magnetic valve, and magnetic valve is being communicated with pH meter by pipeline, and the pipeline that magnetic valve is communicated with pH meter is provided with pH indicating meter and solenoid valve controller.

The utility model can not stop up dosing pump and magnetic valve, can not make the medicament overflow yet, can realize continuous dosing, has reduced day-to-day maintenance, has guaranteed the stable and continuous of follow-up operation.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1, Industrial Wastewater Treatment does not have the chemicals dosing plant of obstruction and comprises lime dissolving tank 2, tap water water inlet pipe 1, reactive tank 4, pH meter 5 and pH indicating meter and solenoid valve controller 6, tap water water inlet pipe 1 is positioned at lime dissolving tank 2 tops, install in the reactive tank 4 and be provided with pH meter 5 and stirring mechanism, lime dissolving tank 2 middle parts one side is equipped with discharge nozzle, and the outlet of discharge nozzle is positioned at reactive tank 4 tops;

Magnetic valve 3 is installed on the tap water water inlet pipe 1, and magnetic valve 3 is being communicated with pH meter 5 by pipeline, installs on magnetic valve 3 and the pipeline that pH meter 5 is communicated with and is provided with pH indicating meter and solenoid valve controller 6.

The principle of work of its operation is such: the dosage that utilizes magnetic valve 3 to control tap water is controlled the water level in the lime dissolving tank 2, if after water level is raised to predeterminated position, the milk of lime in the lime dissolving tank 2 will enter in the reactive tank 4 automatically.Utilize pH meter 5 to show whether the pH value in the reactive tank reaches default pH value, after the pH value is raised to preset value, pH indicating meter and solenoid valve controller 6 will be closed magnetic valve 3 by circuit, this moment, adding of tap water will stop to enter the lime dissolving tank, lime dissolving tank 2 water levels will remain at default water level, and the milk of lime in the lime dissolving tank 2 just can not enter reactive tank 4 by discharge nozzle.Because magnetic valve 3 is adding of control tap water in this device, just can not have blocking problem, and the current of lime dissolving tank 2 are overflowed, its water level remains at default position.

Claims (1)

1, Industrial Wastewater Treatment does not have the obstruction chemicals dosing plant, comprise lime dissolving tank, water inlet pipe, reactive tank, pH meter and pH indicating meter and solenoid valve controller, water inlet pipe is located at lime dissolving tank top, be provided with pH meter and stirring mechanism in the reactive tank, lime dissolving tank middle part one side is provided with discharge nozzle, the outlet of discharge nozzle is positioned at reactive tank top, it is characterized in that:

Water inlet pipe is provided with magnetic valve, and magnetic valve is being communicated with pH meter by pipeline, and the pipeline that magnetic valve is communicated with pH meter is provided with pH indicating meter and solenoid valve controller.
