Description
Technical Field
The utility model relates to a water treatment field specifically is a be applicable to automatic dispensing device of PAC for coal mine waste water treatment.
Background
Coal output of China is the first place in the world, and coal mine water is generated and dischargedThe amount is also the first of the national industrial wastewater. According to statistics, the annual water yield of coal mines in China is 75-80 hundred million m3. The mine water treatment of the coal mine in China starts in the middle of the 80 th year of the 20 th century, and in 5800 coal mines in China at present, a few coal mines which are extracted in advance or subjected to underground sewage disposal and diversion are removed, and most of mine water of the coal mines needs to be treated to reach the environmental emission or resource utilization standard.
No matter which process is adopted to treat the coal mine wastewater, coagulant is required to be added to change the surface property of colloid or suspended particles in the wastewater, so that the attraction energy of the colloid or floc is greater than the repulsion energy to promote the coagulation. The common coagulant comprises aluminum salt and ferric salt, and most of the coagulants currently applied to coal mine wastewater treatment adopt polyaluminium chloride (PAC) in the aluminum salt in consideration of coagulation effect and application cost performance.
The existing dispensing has the following problems: (1) low automation degree
PAC is available in two forms of solid particles and liquid, PAC needs to be prepared into solution with a certain concentration in the adding process, and the solution enters a coagulation reaction tank under pressure or by gravity flow to carry out coagulation reaction. The configuration in-process needs the manual work to put into the chemical tank with the medicament and stirs intensive mixing, and the configuration cycle is generally 8~12h, consequently needs the manual work to give medicine regularly 8~12h, and degree of automation is low, and is contradictory with the "wisdom mine construction theory" advocated in the country.
(2) Uneven chemical concentration
The manual administration is sometimes convenient, and the concentration of the liquid medicine cannot be fixed by adding the medicament before the liquid medicine is not used up. Therefore, the phenomena of unfixed dosing time, unfixed dosing amount and uneven chemical concentration exist.
(3) High dosage of medicament and increased operation cost
The phenomena of indiscriminate dosing and excessive dosing exist in manual dosing, so that the dosage of the medicament is high, the water treatment operation cost is increased artificially, more personnel are involved, the labor cost is high, and the factor is also the factor for increasing the operation cost.
Disclosure of Invention
In order to overcome prior art not enough, the utility model aims at providing a be applicable to automatic dispensing device of PAC for coal mine waste water treatment to solve the concentration that present charge device can't guarantee the liquid medicine among the prior art, can't guarantee automatic dispensing, technical problem such as running cost height.
The technical scheme of the utility model is that: the utility model provides an automatic dispensing device of PAC suitable for coal mine waste water treatment which characterized in that: the chemical agent box comprises a storage box, a spiral conveying device and a chemical agent box, wherein the storage box is connected and communicated with the chemical agent box through the spiral conveying device, a level sensor is arranged inside the chemical agent box, a liquid level sensor is arranged inside the chemical agent box, and a water source electric valve is arranged on the storage box.
The utility model discloses level sensor adopts GUD 15. The utility model discloses level sensor adopts YD 50.
The utility model discloses a theory of operation is: during the use, once store 3 days (suitably increase and decrease according to the ambient humidity condition, the time overlength medicament absorbs water easily and is difficult to transmit) medicament volume in storing up the medicine case, monitor the medicament in service behavior through level sensor, set up level sensor in the chemical tank equally, low liquid level starts auger delivery ware and water source motorised valve in storing up the medicine case, realizes liquid medicine automatic configuration, and high liquid level stops auger delivery ware and water source motorised valve.
The beneficial effects of the utility model are that (1) the utility model discloses realize that the PAC dispenses automatically, dispense and increase degree of automation through the PAC is automatic, with wisdom mine construction theory phase-match. (2) The utility model discloses guarantee to change medicine concentration even, reduce manual operation, realize changing medicine concentration homogeneity through automatic control, guarantee the effect of coagulating. (3) The utility model reduces the operation cost, avoids the phenomena of adding medicine in disorder and adding medicine in disorder, and strictly controls the dosage of the medicine.
