Abstract
The utility model relates to a take double -flow -passage dredge pump of tool bit, this double -flow -passage dredge pump mainly comprise tool bit (1), double -flow -passage impeller (2), the pump body (3), bearing seal (4), (5) five parts on the axle, and its leading features is: added tool bit (1) that a diameter is little than double -flow -passage impeller (2) inlet diameter before double -flow -passage dredge pump impeller, this tool bit and impeller nut's effect is similar, can directly fasten double -flow -passage impeller (2). And provided the structural design method of double -flow -passage dredge pump tool bit, and still alleviate the jam problem of dredge pump in certain degree, guaranteed the impeller percent of pass of dredge pump, prevent to appear blockking up and lead to the motor to transship when having toughness and elastane fiber thing transporting.
Description
Technical field
The present invention relates to a kind of dual channel dredge pump, the dual channel dredge pump of more particularly to a kind of belt blade head.
Background technology
Dredge pump is the media such as a kind of conveying impurity sewage and solid particle, is essentially consisted in abrasion with the difference of clarified water pump
Characteristic and handling capacity requirement are higher.With continuing to develop for industrial and agricultural production, in chemical industry, mine, food, building, papermaking
In the discharge of industrial flow, sanitary sewage and industrial wastewater etc. all conglomeraties etc., it is required for a large amount of conveyings to contain solid particle
The dredge pump of suspension or fibrous suspension liquid.Dredge pump is mainly made up of parts such as pump case, impeller, motors, double fluid
The impeller of road dredge pump is made up of two passages in spatial warping, from the import of impeller central to outlet, channel requirements spaciousness,
It is round and smooth, because its medium handling capacity is strong, runner symmetry is good, operate steadily, reliability it is high, thus modern Non-blinding pump is most
Using two blade impeller.And long fibrous mixture can then wind impeller, blowdown pump seizure is caused, cause certain accident.
Therefore it is badly in need of a kind of transportation performance that both can guarantee that dredge pump, and the good pre-cut cutting filament of energy, can be extensively as dredge pump
The critical problem of application.
The impeller and the pump housing of the dredge pump of prior art are transformed, but long fibrous mixture is not entered
Row pretreatment, therefore dredge pump blocking can not be fundamentally solved, and cause motor that overload phenomenon occurs.
The Chinese invention patent that Patent No. 201110349413.7 discloses a kind of with crushing function Double Channel Pump
Designing Method of Double-flow-passage Impeller, in the patent of invention, inventor give blade main geometric parameters external diameter, exit width,
The construction design method of the design formula of inlet diameter and subtended angle of blade, this method for designing enough improves mobility status, improves double fluid
The lift and efficiency of road pump, and operational reliability.But the dredge pump in above-mentioned patent is filled again without long fibre pretreatment is crossed
Put, therefore can also there is above mentioned problem.
For above-mentioned defect, the present inventor has invented a kind of dual channel dredge pump of belt blade head, in original double fluid
A cutter head is added on the basis of road dredge pump, dredge pump is alleviated in certain degree causes stuck due to crossing long fibre
Problem, also ensure that the impeller percent of pass of dredge pump.
The content of the invention
In order to solve the above problems, the invention provides a kind of dual channel dredge pump of belt blade head.By improving dredge pump
Structure, improve pump inside by property performance, reach pre- anticlogging purpose.
Realizing the technical scheme that above-mentioned purpose is used is：
1st, the dual channel dredge pump is main by cutter head (1), two blade impeller (2), the pump housing (3), axle envelope (4), (5) five, axle
It is grouped into, it is mainly characterized by：A diameter was added before dual channel blowdown pump impeller compared with two blade impeller (2) inlet diameter
Small cutter head (1), the cutter head is similar with the effect of impeller nut, can directly fasten two blade impeller (2).Cutter head (1) is mounted in
On axle, rotated together with two blade impeller (2).Long fibre shape thing and big block to passing through cut, and make it smoothly logical
Cross inside pump, prevent from blocking.
2nd, the cutting edge of the cutter head (1) uses 4~5.When the number of blade is less, threadiness and block cutting are not filled
Point, easy two blade impeller (2) runner；When the number of blade is more, fibrous material is easily wound on cutter head (1), aggravates pump
Block.
3rd, secondary cutter head (1) can also so play certain guide functions with certain taper, and fibrous material will not be made to exist
Blocking is occurred as soon as at pump inlet；Maximum dimension DmaxIt is 0.5~0.6 times of two blade impeller (2) inlet diameter, the height of cutter head (1)
Degree is about maximum dimension Dmax1.2~1.4 times.
According to above-mentioned steps, a kind of dual channel dredge pump of belt blade head can be obtained.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is the dual channel dredge pump part assembly drawing of belt blade head.
Fig. 2 is the dual channel dredge pump cutter head structure figure of belt blade head.
In figure：(1) cutter head, (2) two blade impeller, (3) pump housing, (4) axle envelope, (5) axle
Specific embodiment
Main one diameter of addition before dual channel blowdown pump impeller of the invention is small compared with two blade impeller (2) inlet diameter
Cutter head (1), improve dredge pump convey long fibre shape and big block when by property, prevent transport have toughness
Occur blocking and causing motor overload when with elastomer thing.
This embodiment is that the structure to dredge pump is improved on the basis of original dredge pump is given：
Fig. 1 and Fig. 2 are combination defined in the present embodiment, cutter head (1) before two blade impeller (2) import, cutter head (1),
Two blade impeller (2) and axle rotate together.When long fibre and large-block material enter fashionable, can first be cut by cutter head (1), be made
It is passed through inside pump, prevents from blocking.
Claims (3)
1. a kind of dual channel dredge pump of belt blade head, the dual channel dredge pump is main by cutter head (1), two blade impeller (2), the pump housing
(3), axle envelope (4), the part of axle (5) five composition, it is mainly characterized by：Before dual channel blowdown pump impeller add a diameter compared with
The small cutter head (1) of two blade impeller (2) inlet diameter, the cutter head is similar with the effect of impeller nut, can directly fasten double fluid
Road impeller (2).
2. the dual channel dredge pump of belt blade head according to claim 1, it is mainly characterized by：The cutting edge number of cutter head (1)
4~5 are taken, cutting edge is used and is uniformly distributed.
