Below in conjunction with accompanying drawing the utility model is specifically described:

Fig. 1 is the utility model master pseudosection, and Fig. 2 is a right pseudosection of the present utility model, and as shown in the figure, multi-functional dirt separator comprises the cylindrical shell 11 of cylinder type, and cylindrical shell 11 two ends are separately installed with upper cover 22, low head 9; The bearing 7 that is used to support dirt separator is connected with low head 9; Upper cover 22 tops have seal cover 1, are connected by sealing gasket 2, closed hole circle 3 between seal cover 1 and the upper cover 22; Seal cover 1 is provided with Pressure gauge base 17, exhaust apparatus 16; Cylindrical shell 11 side wall upper part are provided with water outlet base 15, with water outlet base 15 corresponding opposite side middle parts inlet base 5 are arranged on cylindrical shell 11 sidewalls; The position that

first baffle plate

23,13, two baffle plates of second baffle are installed in cylindrical shell 11 internal cavities vertically successively is between inlet base 5 and water outlet base 15; Have a breach on first baffle plate 23, discharging device 20 is installed herein, the automatic ball float of discharging device 20 is stuck in indentation, there, when current passed through, with automatic ball float jack-up, current entered baffle plate 23 upper cavity, when not having current to pass through, automatically ball float falls, and blocks the breach on first baffle plate 23, closed guard 23; Drainage tube 12 passes first baffle plate 23, second baffle 13, and drainage tube 12 is connected with first baffle plate 23, second baffle 13 by first back-up ring 18, second back-up ring 6 respectively; In cylindrical shell 11 internal cavities taper bucket 10 is installed, the position of taper bucket 10 is lower than the position of inlet base 5; In low head 9 bottoms blowdown base 8 is installed; Cylindrical shell 11 sidewalls are provided with backwash base 14, and align with water outlet base 15 between first baffle plate 23, second baffle 13 vertically in the position of backwash base 14; Also be provided with hand hole 19 on cylindrical shell 11 sidewalls, a hole 21, the position of hand hole 19 are between first baffle plate 23, second baffle 13, and the position in a hole 21 is between taper bucket 10 and low head 9; Screen pack 4 is installed on drainage tube 12, and the position of screen pack 4 is between first baffle plate 23, second baffle 13;

Fig. 3 for for A-A of the present utility model to view, as shown in the figure, the inlet base (5) with cylindrical shell (11) sidewall tangent.

According to technical scheme shown in the utility model, can solve the granule dirt can't remove, problems such as screen pack breakage, obstruction, make impurity and granule dirt in the heating system can't enter boiler and heating system, realize safety, economy, the stable operation of boiler and heating system, its concrete mode is as follows:

In order to solve the problem that the granule dirt is difficult to remove, multi-functional dirt separator structurally adopts the locellus design, cylindrical shell 11 internal cavities are divided into three parts, second baffle is deoxygenation, dispensing, exhaust, filter chamber more than 13, second baffle 13 is to being the rotating room between taper bucket 10 lower edges, and remaining is expansion chamber.The heating system backwater flows to the rotating room from the inlet base 5 tangential high speeds at dirt separator middle part, produces very big centrifugal force in the rotating room, makes impurity and fine particle dirt in the system sink to expansion chamber under action of centrifugal force, is discharged by blowdown base 8.

Dirt separator in the past all is to use screen pack to carry out scrubbing separately, in order to reach better scrubbing effect, the general less screen pack of mesh diameter of all selecting for use, screen pack self intensity is descended, under the effect of recirculated water, for the collision of bulky grain dirt impurity, screen pack is very easy to damage, thereby loses the scrubbing effect.In order to address this problem, multi-functional dirt separator is installed in screen pack 4 on the drainage tube 12 of filter chamber, bulky grain shape dirt is removed under rotating room's centrifugal action, make it collision opportunity be arranged with screen pack, and screen pack adopts cylindrical design, and intensity is stronger, and current from inside to outside wash away, stressed even, assurance screen pack safety is used for a long time.

In order to solve the screen pack blockage problem, the screen pack 4 of multi-functional dirt separator is arranged in the filter chamber, top, water quality is carried out the secondary scrubbing, most of dirt is removed in the rotating room in the system, have only in the system lightweight suspension thing to remove with centrifugal force, can be filtered net 4 and stay in the filter chamber, to the local stopping state that produces of screen pack.In order to remove this part lightweight suspension thing, multi-functional dirt separator has a backwash base 14, makes dirt separator have backwashing function, in servicely just can finish flushing in that system is normal.Under system self pressure, current intercept the lightweight suspension thing that gets off with screen pack and break away from screen pack 4 under the effects of back current by screen pack the time, enter expansion chamber by drainage tube 12, discharge through blowdown base 8, and it is unimpeded that screen pack 4 is kept clean.

Multi-functional dirt separator is provided with sponge iron deoxygenation and drug-throwing chamber on top, finish deoxygenation and dosing function on the basis of scrubbing.The seal cover 1 of multi-functional dirt separator is for convenience detach, avoids flange to connect the drawback that loading and unloading are wasted time and energy, and can open at any time, observes the situation of sponge iron and medicament, adds and changes.The sponge iron deoxygenation is one of minimum method of Industrial Boiler deoxygenation cost, and convenient and easy; Add medicament and also be one of effective ways that Industrial Boiler carries out water treatment, and environment is not polluted, after medicament enters boiler, by series of chemical, reduce water hardness, form sediment, discharge by blowdown base 8, keep boiler alkalinity and pH value simultaneously.

Also be provided with a hole 21, hand hole 19 on the multi-functional dirt separator, be convenient to carry out at any time intact situation, corrosion and the expansion chamber contamination situation of checkout facility self-filtering net 4, in time handle.

Multi-functional dirt separator needn't be installed in the heating system minimum point, is installed in the position of being convenient to operate before the pump house pump entry and gets final product.

Multi-functional dirt separator shown in the utility model can prevent that effectively dirt enters boiler in the heating system, prevents fouling of boiler accumulated slag and oxygen corrosion, reduces boiler blow-off number of times and boiler breakdowns, guarantees boiler operatiopn safety, realizes the boiler heating system energy-saving and emission-reduction.
