Description

Electroplate sewage treatment calcium oxide automatic reagent feeding device

Technical Field

The utility model relates to a sewage treatment device, in particular to an automatic calcium oxide dosing device for electroplating sewage treatment.

Background

Electroplating production is usually accompanied by a large amount of toxic and harmful substances, and discharged wastewater must be treated and can be discharged after reaching the discharge standard. At present, the conventional method for sewage treatment adopts chemical treatment by adding medicines, the medicine adding part of the process needs manual operation, and the medicine is added manually, for example, the adding of calcium oxide is manual throwing adding, which wastes time and labor, and dust scatters everywhere along with wind during adding, thus causing environmental pollution.

Compare the improvement of direct shedding interpolation, add water with the barrel and stir the back and water to the effluent water sump, but the proportion when the allotment is uncontrollable, and can deposit at the barrel, deposit viscosity ratio great, artifical unable stirring, once can not use complete back, easily cause the waste.

Disclosure of Invention

The utility model provides an automatic calcium oxide feeding device for electroplating sewage treatment, which has high automation degree, can effectively give medicine safely, dilute quickly, prevent precipitation and supply according to requirements.

The utility model adopts the technical proposal that: the utility model provides an electroplate sewage treatment calcium oxide automatic reagent feeding device, includes the box, and the box inwards stretches into agitator, its characterized in that by upper portion: one side of the box is close to the outer dog-house that sets up to the opposite side of agitator symmetry sets up the air exit, the bottom of box is equipped with the aeration pipe, and the box lower part is equipped with the water pump that is higher than the aeration pipe, and the water pump connects out the three-way valve outside the box through the main pipe, sets up the main valve door on being responsible for, and the three-way valve divides two ways to connect return pipe and dosing pipe, and return pipe and dosing pipe connect back to the box and handle the pond through return valve and dosing valve respectively.

Furthermore, a scale window is arranged on the box body.

Furthermore, the air outlet is connected to a dust bag through an exhaust fan.

Furthermore, the aeration pipe is externally connected with an adjustable air valve.

Further, the return pipe is connected with a right-angle water outlet head arranged at the bottom of the box body.

Furthermore, the material of the box body is 304 stainless steel.

The utility model discloses 304 stainless steel is selected for use to the box material, through the scale window on the box, conveniently measures allotment proportion, when solving manual allocation or thick or rare problem.

The box top air exit external pipeline exhaust fan is even gone up the dust bag, opens when adding calcium oxide powder and airs exhaust, effectively solves the dust problem of wafting, reduces environmental pollution, can also retrieve the purpose of recycling, practicing thrift the cost to the calcium oxide in the dust bag.

The dog-house is seted up on the diagonal angle of air exit, increases the dust absorption distance, enlarges the dust absorption area, can be so that heavier powder can fall into the water tank fast, only absorb lighter and powder that wafts easily and avoid too much raw materials to be directly siphoned away by the exhaust fan, promotes work efficiency.

The stirrer is arranged at the center of the box body, so that raw materials put into the water tank can be stirred and melted into water timely and efficiently.

For preventing that bottom of the box portion mixer can't effectively stir, increase the aeration pipe around the bottom, multi-direction division has little gas outlet to assist the mixer stirring, enlarge stirring range, improve stirring efficiency, and for preventing need not lead to calcium oxide solution to deposit for a long time, under the device not electrified condition, admit air by adjustable air valve trace and make solution be in the stirring state that rolls always, avoided the deposit of long-term time spent calcium oxide not even harden completely, get rid of the jam hidden danger of device inner pipeline, and be favorable to not extravagant, utilize control cost completely.

The water pump is erected away from the bottom of the water tank to avoid the aeration pipe and the stirrer; the main pipe connected with the water pump is provided with a tee joint which is respectively connected with a return pipe and a dosing pipe, the return pipe returns to the box body, the dosing pipe is used for feeding the medicine to the treatment tank, and the amount of the discharged medicine can be adjusted by adjusting the opening degree of the valve; the return pipe can also recoil the solution in the box body, protect the pipeline and prolong the service life of the pipeline. When the valve of the main pipe is fully opened and the valve of the return pipe is fully closed, the whole pressure of the water pump enters the dosing pipe, so that the solution quickly enters the treatment tank, when the valve of the main pipe is opened and the valve of the return pipe is properly opened, the pressure of the main pipe is reduced to control the flow rate of the solution, the solution flowing back at the moment enters the tank body, the solution flowing back is made to participate in the stirring motion of the solution by installing a right-angle water outlet head at the bottom of the tank body, the energy waste is avoided, when the valve of the main pipe is closed and the valve of the return pipe is opened, the solution in the tank body can be pressurized and returned again through the water pump, the activation operation after long-term precipitation or hardening can be realized, in addition, a stirrer blade or a rod is possibly wrapped after long-term precipitation, the air outlet of an air pipe is blocked, the effective stirring can not be realized at the moment, the impact force of the backflow of the water pump is utilized to quickly impact and dissolve precipitates, and the safe, stable and efficient use is ensured.
