Description
Technical field
The present invention relates to a kind of pumping equipment, in particular for liquid medium to a kind of pumping equipment on solid material counterflow extraction apparatus.
Background technology
In the prior art, with the present invention closest to technology be the patent " pumping equipment of a kind of extraction tube " (patent No. 200810238617.1) of the present inventor's innovation and creation, it includes the spiral propeller being made up of with the helical blade being fixed on cardan shaft in extraction tube and extraction tube cardan shaft, 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, on the top of extraction tube inner chamber and be fixed with striker plate between drain pipe and feed pipe, this striker plate is positioned at the end of helical blade. Owing to this striker plate is positioned at the top of extraction tube inner chamber, extracting solution flows through striker plate and discharges from being positioned at the drain pipe extracting upper top from bottom, this striker plate cannot stop that settling material in extracting solution enters in discharge opeing pipeline section, owing to 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, it is accomplished by configuration processing mechanism, make this be partially into the precipitum of discharge opeing pipeline section to discharge with extracting solution, just can prevent long time integration from causing the possibility that discharge opeing pipeline section blocks; It addition, spiral propeller drives axle traverse extraction tube closure plate, the mechanical seal configured, owing to being totally immersed in extracting solution, and spiral propeller swings relatively big, to the abrasion of mechanical seal comparatively fast, bigger, mechanical seal is caused very easily to damage, thus causing the leakage of extracting solution. This is the weak point existing for prior art.
Summary of the invention
The technical problem to be solved, it is simply that the deficiency existing for prior art, it is provided that a kind of countercurrent extraction pumping equipment preventing the bigger precipitation material entrance discharge opeing pipeline section of proportion and forming accumulation problem. The present invention also provides for a kind of solving the extracting solution countercurrent extraction pumping equipment from propeller shaft mechanical seal leakage problem.
This programme is achieved by the following technical measures: a kind of countercurrent extraction pumping equipment, it includes extraction tube, extraction tube is provided with striker plate, it is characterized in that striker plate is perpendicular to extraction tube central axis and arranges, between whole outer peripheral edge and the extraction tube inwall of striker plate formed be tightly connected and striker plate extraction tube is separated into independent discharge opeing pipeline section and extraction pipeline section two parts, discharge opeing pipeline section is provided with overflow pipe, overflow pipe includes overflow pipe inlet and overflow pipe liquid outlet, extracts pipeline section and is connected with discharge opeing pipeline section by overflow pipe;Striker plate has extracting solution inflow entrance; Overflow pipe inlet docks with extracting solution inflow entrance, and overflow pipe liquid outlet is higher than overflow pipe inlet.
The concrete feature of this programme also has, and has the extension of upward opening at discharge opeing pipeline section top, and overflow pipe liquid outlet extends in extension; There is cover plate on extension top, on the cover board has air tube.
Extraction tube also has propeller and impeller drive shaft, has closure plate in extraction tube end; Propeller is positioned at extraction pipeline section, and impeller drive shaft is connected through striker plate and closure plate with the driving device being positioned at outside extraction tube. Mechanical sealing member is had between closure plate and impeller drive shaft; Sealing member is had between impeller drive shaft and striker plate.
It is positioned at overflow pipe liquid outlet at described overflow pipe outer wall and is arranged below screen barrel.
Extracting, pipeline section there is material inlet port.
Extracting solution outlet is had bottom discharge opeing pipeline section.
Extract the extracting solution in pipeline section and flow in extracting solution inflow entrance, enter overflow pipe from inlet, flow through overflow pipe liquid outlet and enter screen barrel, flow in discharge opeing pipeline section after filtration, then discharge from the extracting solution outlet being positioned at bottom discharge opeing pipeline section.
Material enters from material inlet port and extracts pipeline section, 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; Sealing member is had between impeller drive shaft and striker plate.
The beneficial effect of this programme can be learnt according to the narration of such scheme, due in this scenario, extract pipeline section and discharge opeing pipeline section is cut off completely by striker plate, only connected by 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, so, extract the extracting solution in pipeline section and only just can flow through in overflow pipe entrance discharge opeing pipeline section higher than overflow pipe liquid outlet, discharge opeing pipeline section and atmosphere is kept due to air tube, the extracting solution extracted in pipeline section enters in discharge opeing pipeline section by overflow manner, flooding velocity is slower, so, in extracting solution heavier, fall to the particulate matter extracted bottom pipeline section, just cannot with extracting solution from the bottom extracting pipeline section, flow through overflow pipe upwards and from the overflow pipe liquid outlet higher than extraction tube top to enter discharge opeing pipeline section, thus preventing settling particulate matter to enter in discharge opeing pipeline section, simultaneously, can extracting solution inflow entrance be positioned over below striker plate, can avoid again extracting and pipeline section float on extracting solution top particulate matter entrance overflow pipe and flows into discharge opeing pipeline section, thus reducing the content of sedimentation, floating particle thing in extracting solution, reduce and extracting intensity and the difficulty that later process filters, it addition, the external screen barrel of overflow pipe liquid outlet, it is possible to retain part and flow into the large-scale particulate matter of overflow pipe, be effectively prevented the damage to external extracting solution outlet infusion pump of the large-scale particulate matter.
The extracting solution entered in discharge opeing pipeline section is discharged in time, and keeping discharge opeing pipeline section extracting solution be not a half tubulose state, so, extracting solution will not cover the mechanical sealing member between driving axle and closure plate, it is to avoid the poorly sealed extracting solution leakage problem caused of mechanical sealing member. There is sealing member between impeller drive shaft and striker plate, reduce extracting solution and flow through from the gap between impeller drive shaft and striker plate.
