Description
Technical field
The utility model relates to a kind of boiler cleaning device, especially relates to a kind of chemicals dosing plant that dissolves boiler scale.
Background technology
Usually contain a large amount of calcium, magnesium ion in the boiler feedwater, chemical reaction takes place in easily under hot environment, and perhaps condensing crystallizing is produced water-fast incrustation scale, and firm attachment is on boiler bottom or wall.And this incrustation scale is the non-conductor of heat, can seriously hinder the heat conduction, on the one hand or reduce the thermal efficiency of boiler greatly, waste a large amount of energy, during the inequality of seriously being heated on the other hand even can cause the bursting of boilers, cause serious production, life accident, simultaneously, compounds such as calcium magnesium easily and the metal reaction of boiler cause bigger damage to boiler itself.
In the practice, the user is when giving boiler water supply, generally water is softened, desalination, but still unavoidably there is the small amount of calcium magnesium ion to enter in the boiler, for reducing of the harm of this part calcium ions and magnesium ions to boiler, adding in boiler at present and adding phosphate before the entry in advance is a kind of suitable way, usually be placed on and finish in the chemicals dosing plant and add phosphatic work, phosphate and calcium ions and magnesium ions reaction, produce subphosphate, and subphosphate is a kind of soft grain slag, easily gets rid of with incrustation scale, can't stick to and become incrustation scale in the boiler, and the water in the chemicals dosing plant can be by cross current to boiler.Behind soups such as adding phosphate, usually also include a paddle in the present chemicals dosing plant, but setting that should the list paddle can not be carried out comprehensive stirring to chemicals dosing plant, mixing effect is relatively poor, be unfavorable for promoting the reaction of phosphate and calcium ions and magnesium ions, can not fully pulverize the phosphate or the subphosphate of solid.
In view of this, the present utility model people is active development research, and for improving the deficiency of the said goods, through the permanent research and experiment of making great efforts, development and Design goes out the two oar chemicals dosing plants of single shaft of the present utility model finally.
The utility model content
The technical problems to be solved in the utility model provides the two oar chemicals dosing plants of a kind of single shaft, can solve in the prior art and singly will stir the problem insufficient, that the scope of operation is little in the pressue device.
For achieving the above object, the technical solution adopted in the utility model is: the two oar chemicals dosing plants of a kind of single shaft, comprise chemicals dosing plant body 1, offer dosing mouth 2 and water inlet 3 on chemicals dosing plant body 1 top, be provided with a sewage draining exit 4 and a delivery port 5 in chemicals dosing plant body 1 bottom, chemicals dosing plant is provided with a central shaft 6 from top to bottom, described central shaft 6 tops link to each other with reductor agitator 7, in chemicals dosing plant body bottom and middle part one paddle 8 is set respectively, described two paddles 8 are connected on the described central shaft 6.
Preferably, offer a dissolving frame 9 on chemicals dosing plant body top.
Preferably, described delivery port is outside equipped with an outlet filter screen 10.
Preferably, described delivery port is provided with second filter screen 11 by an outlet filter screen and a cross current in the described water pipe.
After adopting the technical solution of the utility model, owing to one paddle respectively is set in chemicals dosing plant body bottom and middle part, described two paddles are connected on the described central shaft, therefore, the double-deck paddle that is provided with has improved stirring and crush efficiency greatly, adopt this unique design, make the utility model product contrast prior art, can reach and practical improvement such as raise the efficiency.
Description of drawings
Fig. 1 is the utility model one embodiment chemicals dosing plant workflow schematic diagram.
Fig. 2 is the utility model one embodiment chemicals dosing plant structural representation.
The specific embodiment
Below in conjunction with drawings and embodiments the utility model is described in further detail.
See also Fig. 1, be the workflow schematic diagram of the utility model one embodiment.The control system of chemicals dosing plant of the present utility model can adopt micro computer to finish, but the user as required idiomorphism the administration timing of drug and the frequency are set, after controller sends instruction, can realize dosing and then realize workflows such as stirring, blowdown, water outlet.
Referring to Fig. 2, be the utility model one embodiment chemicals dosing plant structural representation, described chemicals dosing plant comprises chemicals dosing plant body 1, it is cylindrical that top can be set, the bottom is a conical structure, offer dosing mouth 2 and water inlet 3 on chemicals dosing plant body 1 top, with medicine and water inlets such as convenient interpolation phosphate, be provided with a sewage draining exit 4 and a delivery port 5 in chemicals dosing plant body 1 bottom, 4 pairs of reactions of sewage draining exit, pulverizing the grain slag that sinks discharges, chemicals dosing plant is provided with a central shaft 6 from top to bottom, described central shaft 6 tops link to each other with reductor agitator 7, deceleration agitator 7 can be a motor, in order to provide power to make central shaft 6 rotations, in chemicals dosing plant body bottom and middle part one paddle 8 is set respectively, described two paddles 8 are connected on the described central shaft 6, described two central shafts can be realized the medicine that adds is fully stirred, to promote the reaction of medicine and water intermediate ion, simultaneously, two paddles rotate at a high speed, can pulverize the impurity of producing such as grain slag, so that discharge outside the chemicals dosing plant.
Preferably, offer a dissolving frame 9 on chemicals dosing plant body top, when medicine drops into from dissolving frame 9, can be convenient to medicine and fully dissolve.
Preferably, described delivery port is outside equipped with an outlet filter screen 10, can realize water outlet is filtered, and places grain slag and flows into boiler by water pipe.
Preferably, described delivery port is provided with second filter screen 11 by an outlet filter screen and a cross current in the described water pipe, further to increase water quality, get rid of impurity such as grain slag fully.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
