Description
Technical field
The utility model relates to pipeline negative pressure device for transporting objects, specifically provides a kind of Centrifugal Vacuum pump assembly.
Background technique
The Centrifugal Vacuum pump assembly that existing device for transporting objects uses, due to material enter blower fan after to produce with the impeller of High Rotation Speed and impact and rub, cause impeller failure, so existing Centrifugal Vacuum pump assembly mostly by centrifugal vacuum pump and deduster with the use of, wherein the entrance of deduster is connected with on-the-spot suction tube or negative-pressure pipeline, the outlet of deduster is connected with centrifugal vacuum pump, by the material in deduster filtering gas, centrifugal vacuum pump unit energy is run well, shortcoming is that the filter screen in deduster adds gas-flow resistance and inleakage, Centrifugal Vacuum pump overall efficiency is reduced, and deduster is along with the accumulation of material, the stability of unit operation will decline, need often to clear up deduster, safeguard more frequent, add operating cost.
Summary of the invention
The purpose of this utility model is to provide and does not a kind ofly need dedusting and the Centrifugal Vacuum pump assembly of direct conveying material, and this unit working efficiency is high, stable, long service life.
The technical solution of the utility model is: Centrifugal Vacuum pump assembly, it is characterized in that: there is the first vacuum pump, second vacuum pump, first air inlet square chest, second air inlet square chest and dual-axle motor, first, two running wheels of the second vacuum pump and the two axial ends of dual-axle motor pto＝power take-off are connected respectively, first, the top of the second air inlet square chest is respectively equipped with import, side or bottom are respectively equipped with outlet, the outlet of the first air inlet square chest is communicated with the suction port of the first vacuum pump, the air outlet of the first vacuum pump is by the inlet communication of reflow pipe and the second air inlet square chest, the outlet of the second air inlet square chest is communicated with the suction port of the second vacuum pump, described first, running wheel in second vacuum pump is provided with cylindrical outlet, this outlet is enlarging, the surface of running wheel is provided with nichrome scuff-resistant coating.
Hit blade along being fixed with several week in the enlarging of described running wheel cylindrical outlet, running wheel is furnished with primary blades, and described primary blades is made up of linear leaf and short blade arranged in sequence, and each strike blade and each primary blades are staggered and arrange.
The utility model has the advantages that: eliminate the deduster in conventional centrifugal vacuum pump unit, material is directly delivered to discharge nozzle from negative-pressure pipeline by air inlet square chest by two-stage vacuum pump, namely do not need dedusting can direct conveying material, effectively can improve the working efficiency of Centrifugal Vacuum pump assembly, air inlet square chest wherein can current stabilization, enter the suction port of one-level vacuum pump with making uniform stream, working stability; Formation buffer area, space between the enlarging of running wheel cylindrical outlet and shell, allows material be spread by enlarging under the influence of centrifugal force, reduces material to the impact of vacuum pump volute body, extends the working life of vacuum pump casing; On running wheel, form nichrome scuff-resistant coating by heat-spraying technology, make running wheel have wear-resisting top layer, ensure the running of Centrifugal Vacuum pump assembly long-time stable; Two running wheels operationally, Impact direction is relative, and coaxial oppositely installation can offset the end thrust of running wheel to dual-axle motor pto＝power take-off, alleviates the collapsing force of end thrust to pto＝power take-off spring bearing, extend the dual-axle motor life-span, make the work of Centrifugal Vacuum pump assembly more stable.
Hit the intensity that blade can increase the outlet of active wheel cylindrical, and utilize centrifugal action larger particles material can be smashed in order to avoid blocking pipeline, the pressure of the gas flow between the outlet of active wheel cylindrical and shell is higher, now hitting blade can make the outlet of active wheel cylindrical become socket type rectification with between outer hull shape, in this space, the kinetic pressure of gas changes static pressure into, improves the efficiency of running wheel; Short blade can reduce resistance when material enters vacuum pump, improves the through-flow flow of Centrifugal Vacuum pump assembly.
