Description
Technical field
The present invention relates to mud and sewage biogas residue and biogas liquid field, particularly relate to a kind of spiral shell heart for carrying high level cadre's rheid
Pump.
Background technology
Under normal circumstances, higher to dry solid content, during in particular for material solid content more than 8%, common sewage pump is easy
Blocking, quick abrasion, be difficult to effectively conveying, and when containing a large amount of fibrous material (changing food waste, municipal garbage, mud or
The tunning of agricultural stalk), use screw pump to be easily generated and tie knots and wear phenomenon.Owing to screw pump belongs to horizontal type structure, its
Material cavity linearly structure, fed distance farther out, is easily caused material fouling in material cavity body, forms blocking；Screw pump
Conveying function rely primarily on the friction of rotor and extruding realizes, the damage causing rotor is serious, and the life-span is shorter, and maintenance is changed
Frequently；A charging aperture typically can only be offered, it is impossible to be directly connected multiple container simultaneously, need multiple stage spiral shell on the screw pump pump housing
Bar pump associated working, pipeline connection increases relatively, and the fed distance and the resistance that considerably increase pipeline are damaged, and add simultaneously and safeguard into
This.
Summary of the invention
For problem of the prior art, the present invention provides a kind of shortening fed distance, minimizing pump housing quantity, the minimizing pump housing to account for
Ground area, prevent chamber indoor wear and the spiral shell heart pump for carrying high level cadre's rheid tied knots.
For achieving the above object, the present invention adopts the following technical scheme that

The spiral shell heart pump housing 23 of vertical setting；
Multiple spiral shell heart pump charging apertures 11, it is directly separately positioned in the vertical side walls of spiral shell heart pump housing 23, for spiral shell heart pump chamber
The material inlet of body 23；
Spiral shell heart pump discharging opening 19, it is arranged in the vertical side walls of spiral shell heart pump housing 23, for the material outlet of spiral shell heart pump housing 23；
It is positioned at spiral shell heart pump housing 23 and is arranged on the scroll casing type diversion chamber of bottom, for material diversion being gone out spiral shell heart pump housing
23, the spiral case discharging opening 18 including volute chamber 14, being arranged on volute chamber 14 discharging opening and the spiral case being arranged on volute chamber 14 top
Fixing seat 13, described spiral case discharging opening 18 is communicated to spiral shell heart pump discharging opening 19；
It is vertically provided at the lower shaft 17 in spiral shell heart pump housing 23；
Vertically arranged and be sleeved on the spiral shell rachis 20 of lower shaft 17 bottom, including being the most spirally distributed in outside spiral shell rachis 20
The spiral shell blade 21 in face, described spiral shell blade 21 includes the conveying spiral shell blade being arranged on top and is arranged on the centrifugal spiral shell blade of bottom,
Described conveying spiral shell blade is located at spiral case and fixes in the vertical through holes arranged on seat 13, for being transported to from top to bottom by material
In volute chamber 14, described centrifugal spiral shell blade is positioned at volute chamber 14, and the material in driving volute chamber 14 is along volute chamber 14
Wall does centrifugal motion, and the diameter of described centrifugal spiral shell blade is more than the diameter of conveying spiral shell blade.
Further, the blade diameter of described conveying spiral shell blade is gradually increased from the top down.
Further, described centrifugal spiral shell blade and conveying spiral shell blade centered by axle be coaxially disposed.
Further, the diameter of centrifugal spiral shell blade is more than the diameter twice of conveying spiral shell blade.
Further, described spiral shell blade 21 is the distribution of single-wire helix formula or multi-line spiral distribution.
Further, the inner of spiral shell blade 21 is fixed on the lateral surface of spiral shell rachis 20, and along spiral shell rachis 20 from top to bottom
Spiral distribution, the outer end of spiral shell blade 21 is inclined upwardly, and the angle formed between the central shaft of spiral shell blade 21 and spiral shell rachis 20 is
Acute angle.
Further, also include the lower shaft axle sleeve 8 being sleeved on lower shaft 17 top, be used for isolating material and contact with lower shaft 17.
Further, also including the lower shaft stage clip 22 being locked on lower shaft 17, the top of described spiral shell rachis 20 is buckled in the end
Axial compression spring 22, the termination, bottom of lower shaft 17 is fixed on the bottom of spiral shell rachis 20.
Beneficial effect:
The present invention compared with prior art, has the advantage that
(1) spiral shell heart pump housing is big chamber, and volume is relatively big, is full of material in big chamber, and when spiral shell heart transport pump material, material leads to
Cross self-gravity action automatically into chamber, effectively prevent chamber indoor wear and tie knots；
(2) multiple spiral shell heart pump charging apertures are directly separately positioned on the vertical side walls of spiral shell heart pump housing, hence it is evident that be different from one
Arranging the structure of multiple branches feed pipe on feed pipe, the structure of the present invention makes all can be independent between each tank body and discharging opening
Ground conveying material；
(3) spiral shell heart pump body of wall uses vertical setting, had both decreased the floor space of the pump housing, and had shortened again the material between each tank body
Fed distance, prevents the material in pipeline from depositing；
(4) vertically arranged in the present invention and spiral shell rachis, uses two-part structure, including being arranged on the conveying spiral shell blade on top and setting
Putting the centrifugal spiral shell blade in bottom, conveying spiral shell blade is located at spiral case and fixes in the vertical through holes arranged on seat, centrifugal spiral shell blade
Being positioned at volute chamber, the material in driving volute chamber does centrifugal motion along volute chamber inwall, and the diameter of centrifugal spiral shell blade is big
In the diameter of conveying spiral shell blade, the blade of conveying spiral shell blade is less relative to centrifugal spiral shell blade, is mainly used in material from upper past
Being transported in volute chamber, in course of conveying, extruding and abrasive action power to material are the least, disclosure is particularly well suited to defeated lowerly
Send high solid fluid-mixing, tie knots and the phenomenon such as abrasion when solving more existing delivery pump conveying high level cadre's rheid；Centrifugal spiral shell
Blade combines spiral case and jointly acts on, it is possible to the high level cadre's rheid in spiral case is produced bigger centrifugal force, thus by high dry solid stream
Body transfers out from spiral shell heart pump housing.
