Abstract
The invention relates to an automatic reagent feeding device of a combined type automatic reagent feeding sledge for pretreating raw water of a power plant. The automatic reagent feeding device comprises a vacuum suction pump (1), a hose (2), a suction head (3), a hopper (4), a hopper pneumatic valve (5), a pre-wetting device (6), a reagent atomizing mixed ejector (7), a dry powder pushing double-screw conveyor (8), an electrical control system (9) and a water supply system (10). The automatic reagent feeding device disclosed by the invention has the beneficial effects of effectively preventing the powder from being wet and caked by sucking a material by adopting the vacuum suction pump, and being free of pulsation and high in blending accuracy by pushing the material by adopting a screw rod.
Description
Technical field
The present invention relates to a kind of automatic medicine adding apparatus of pretreated combined type Automatic Dosing sledge of former water of power plant, belong to power plant's complete set of equipments technical field.
background technology
In the pretreatment of the former water of power plant domestic at present, in Automatic Dosage Control of Additives, there are following two major defects: 1, flow signal fluctuates frequently and SCD jitter, and these all cause system to be difficult to stablize, and operating mechanism constantly regulates, cannot drop into automatically; 2, under different condition of water quality, the SCD response curve generation great change of dosing, cause regulating parameter improper, SCD value can be caused in wide variation if do not revise, dosing dosage is improper, system is difficult to stable operation, thus cisco unity malfunction, so the pretreated combined type dosing sledge of the former water of power plant is all without Automatic Dosing or be difficult to realize Automatic Dosing function.
Summary of the invention
Object of the present invention overcomes the deficiency of above technology, a kind of statistical analysis by coagulation experiment and historical data is provided, what draw Various Seasonal adds rule, adopt different algorithms, change the PI parameter of flow proportional coefficient and closed-loop control, according to turbid ity signal, and further consider the impact on coagulation of coolant-temperature gage, pH value, improve the automatic medicine adding apparatus of the pretreated combined type Automatic Dosing sledge of the former water of a kind of power plant of Automatic Dosing function.Be achieved through the following technical solutions for achieving the above object: a kind of automatic medicine adding apparatus of pretreated combined type Automatic Dosing sledge of former water of power plant, by vacuum intake pump (1), flexible pipe (2), suction head (3), hopper (4), hopper operated pneumatic valve (5), pre-wet device (6), medicament atomization mixing jet device (7), dry powder pusher double-screw conveyor (8), electric control system (9), water supply system (10) forms, under it is characterized in that described hopper (4), described hopper operated pneumatic valve (5) is installed, described pre-wet device (6) is connected to hopper operated pneumatic valve (5), under described medicament atomization mixing jet device (7) is arranged on pre-wet device (6).Described pre-wet device (6) is conical warehouse.Described dry powder pusher double-screw conveyor (8) is arranged in hopper (4).
the invention has the beneficial effects as follows:
1, the suction of vacuum intake pump is adopted effectively to prevent material powder to make moist caking;
2, adopt screw rod pusher, pulse free, the batching degree of accuracy is high.
