The limestone adding device of the utility model does not block a dosing pump and an electronic valve, can prevent drug from overflowing, can realize the continuous quantitative dosing and automatic control, reduces the cost for daily maintenance, and guarantees the stability and continuity of subsequent operation.
Description
Technical field
The utility model relates to a kind of throwing device, particularly relates to a kind of lime throwing device.
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, and the dosage of lime is also wayward.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, utilize what of magnetic valve and pH meter control milk of lime dosage,, frequent stop production to overhaul because impurity and milk of lime easily stop up magnetic valve, influenced the effect that adds continuously and flocculate of lime, the normal operation of follow-up sewage disposal has been produced very big influence.
The utility model content
The main technical problems to be solved in the utility model is, provides a kind of and can not stop up dosing pump and magnetic valve, can realize quantitatively adding and the lime throwing device of control automatically of lime simultaneously again.
For solving the problems of the technologies described above, the utility model provides a kind of lime throwing device, comprises the lime dissolving tank, also comprise reactive tank and water inlet pipe, water inlet pipe is located at lime dissolving tank top, and lime dissolving tank one side is provided with discharge nozzle, and the outlet of discharge nozzle is positioned at reactive tank top.
Described lime throwing device also comprises pH meter and inlet control device, and pH meter is located in the reactive tank, and inlet control device is connected with water inlet pipe and pH meter respectively.
Preferably, described inlet control device comprises magnetic valve and solenoid valve controller, and magnetic valve is located on the water inlet pipe, and solenoid valve controller is connected with magnetic valve and pH meter respectively.
Further preferred, described lime throwing device also is provided with the pH indicating meter, and the pH indicating meter is connected with pH meter and solenoid valve controller respectively.
Preferably be provided with whipping appts in described lime dissolving tank and/or the reactive tank.
The beneficial effects of the utility model are:
Lime throwing device of the present utility model can not stop up dosing pump and magnetic valve, can not make the medicament overflow, and can realize continuously, quantitative dosing and control automatically, reduced day-to-day maintenance, guaranteed the stable of follow-up operation and continuously.
Description of drawings
Fig. 1 is a kind of lime throwing device structural representation of the present utility model.
Embodiment
The utility model provides a kind of novel lime throwing device, can be used for the neutralizing treatment of acid wastewater in mine, can not stop up dosing pump and magnetic valve, can realize quantitatively adding and control automatically of lime simultaneously again.
Nothing of the present utility model is stopped up, quantitative lime throwing device comprises lime dissolving tank, water inlet pipe, reactive tank, pH meter, pH indicating meter and solenoid valve controller, water inlet pipe is located at lime dissolving tank top, be provided with whipping appts in dissolving tank, the reactive tank, be provided with pH meter in the reactive tank simultaneously, 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 pH meter by pipe connection, and the pipeline that magnetic valve is communicated with pH meter is provided with pH indicating meter and solenoid valve controller.
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, nothing is stopped up, quantitative lime throwing device comprises lime dissolving tank 2, tap water water inlet pipe 1, reactive tank 4, pH meter 5, pH indicating meter and solenoid valve controller 6, tap water water inlet pipe 1 is positioned at lime dissolving tank 2 tops, pH meter 5 and whipping appts are installed in the reactive tank 4, lime dissolving tank 2 bottoms also are equipped with whipping appts, middle part one side is equipped with discharge nozzle 7, and the height of lime dissolving tank is than reactive tank height, and the outlet of discharge nozzle 7 is positioned at reactive tank 4 tops.
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 7.Because magnetic valve 3 is adding of control tap water in this device, milk of lime is to enter reactive tank by overflow, just blocking problem can not had, the current of lime dissolving tank 2 are overflowed, its water level remains at default position, and solenoid valve controller and pH indicating meter link together, thus realized lime quantitatively, add continuously.
Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
