Description
Technical field
The utility model relates to a kind of pumping equipment, especially for liquid medium to a kind of pumping equipment on solid material counterflow extraction apparatus.
Background technology
In the prior art, the technology the most close with the utility model is patent " a kind of pumping equipment of extraction tube " (patent No. 200810238617.1) of the present inventor's innovation and creation, it to include in extraction tube and extraction tube by cardan shaft and is fixed on the spiral propeller that the helical blade on cardan shaft forms, feed pipe is had in one end of extraction tube, extraction tube upper top between described extraction tube side and feed pipe has drain pipe, striker plate is fixed with on the top of extraction tube inner chamber between drain pipe and feed pipe, this striker plate is positioned at the end of helical blade.Because this striker plate is positioned at the top of extraction tube inner chamber, extract flows through striker plate from bottom and discharges from being positioned at the drain pipe extracting upper top, this striker plate cannot stop that in extract, sedimentation material enters in discharge opeing pipeline section, because discharge opeing pipeline section does not have the effect of spiral propeller, the sedimentation material entering discharge opeing pipeline section cannot be discharged from the drain pipe being positioned at extraction tube upper top again, just need configuration process mechanism, the precipitum making this part enter discharge opeing pipeline section is discharged with extract, the possibility that just can prevent from long time integration from causing discharge opeing pipeline section blocking; In addition, spiral propeller driving shaft passes extraction tube closure plate, the mechanical seal configured, owing to all immersing in extract, and spiral propeller swings comparatively large, to the wearing and tearing of mechanical seal comparatively fast, larger, cause mechanical seal very easily to damage, thus cause the leakage of extract.This is the weak point existing for prior art.
Summary of the invention
Technical problem to be solved in the utility model is exactly for the deficiency existing for prior art, provides a kind of larger precipitation material of proportion that prevents enter discharge opeing pipeline section and form the counter-flow extraction pumping equipment of accumulation problem.The utility model also provides a kind of and solves the counter-flow extraction pumping equipment of extract from propeller shaft mechanical seal leakage problem.
This programme is achieved by the following technical measures: a kind of counter-flow extraction pumping equipment, it comprises extraction tube, striker plate is provided with in extraction tube, it is characterized in that striker plate is arranged perpendicular to extraction tube central axis, formed between the whole outer peripheral edge of striker plate and extraction tube inwall and to be tightly connected and extraction tube is separated into independently discharge opeing pipeline section and extract pipeline section two parts by striker plate, overflow pipe is provided with in discharge opeing pipeline section, overflow pipe comprises overflow pipe inlet and overflow pipe liquid outlet, extracts pipeline section and is communicated with discharge opeing pipeline section by overflow pipe; Striker plate has extract inflow entrance; Overflow pipe inlet docks with extract inflow entrance, and overflow pipe liquid outlet is higher than overflow pipe inlet.
The concrete feature of this programme also has, and have the extension of upward opening at discharge opeing pipeline section top, overflow pipe liquid outlet extends in extension; There is cover plate on extension top, on the cover board has respiratory siphon.
In extraction tube, also have propeller and impeller drive shaft, have closure plate in extraction tube end; Propeller is positioned at and extracts pipeline section, and impeller drive shaft is connected with the drive unit being positioned at extraction tube outside with closure plate through striker plate.Mechanical sealing member is had between closure plate and impeller drive shaft; Seal is had between impeller drive shaft and striker plate.
Be positioned at below overflow pipe liquid outlet at described overflow pipe outer wall and screen barrel is set.
Extraction pipeline section there is material inlet port.
Extract outlet is had bottom discharge opeing pipeline section.
The extract extracted in pipeline section flows in extract inflow entrance, enters overflow pipe, flow through overflow pipe liquid outlet and enter screen barrel from inlet, flows in discharge opeing pipeline section, then discharge from the extract outlet be positioned at bottom discharge opeing pipeline section after filtering.
Material enters extraction pipeline section from material inlet port, is pushed to the scum pipe of the extraction tube other end by propeller.
Mechanical sealing member is had between closure plate and impeller drive shaft; Seal is had between impeller drive shaft and striker plate.
The beneficial effect of this programme can be learnt according to describing of such scheme, due in this scenario, extraction pipeline section and discharge opeing pipeline section are cut off completely by striker plate, be communicated with by means of only overflow pipe, due to overflow pipe inlet under, overflow pipe liquid outlet is higher than overflow pipe inlet, and overflow pipe liquid outlet is positioned in the extension of discharge opeing pipeline section top upward opening, make overflow pipe liquid outlet concordant with extraction tube top or higher than extraction tube top, like this, the extract extracted in pipeline section only just can flow through overflow pipe higher than overflow pipe liquid outlet and enter in discharge opeing pipeline section, because respiratory siphon keeps discharge opeing pipeline section to be communicated with air, the extract extracted in pipeline section enters in discharge opeing pipeline section by overflow manner, flooding velocity is slower, like this, heavier in extract, fall to the particle extracted bottom pipeline section, just cannot with extract from the bottom of extracting pipeline section, flowing through overflow pipe upwards enters discharge opeing pipeline section from the overflow pipe liquid outlet higher than extraction tube top, thus prevent settling particulate matter to enter in discharge opeing pipeline section, simultaneously, can extract inflow entrance be positioned over below striker plate, can avoid again floating on extract top particle in extraction pipeline section enter overflow pipe and flow into discharge opeing pipeline section, thus reduce the content of sedimentation in extract, floating particle thing, reduce the intensity and difficulty of extracting later process filtration, in addition, the external screen barrel of overflow pipe liquid outlet, can retain the large-scale particle that part flows into overflow pipe, effectively prevent large-scale particle to the damage of external extract outlet infusion pump.
The extract entered in discharge opeing pipeline section is discharged in time, and keep discharge opeing pipeline section extract to be not a half tubulose state, like this, extract can not cover the mechanical sealing member between driving shaft and closure plate, avoids the poorly sealed extract leakage problem caused of mechanical sealing member.There is seal between impeller drive shaft and striker plate, reduce extract and flow through from the gap between impeller drive shaft and striker plate.
