The manual sewage drainage pump has simple structure, high practical application value, and convenience in processing, and is convenient for promotion and application.
Description
Technical field
This utility model relates to a kind of dredge pump, relates in particular to the manual blowdown pump that confined spaces such as a kind of down-hole refuge or survival capsule use.
Background technology
When mine disaster takes place, the hedging personnel that hide in confined spaces such as survival capsule or refuge need to drain, appropriately whether excreta handled, whether cleaning in time is directly connected to the air quality in the confined space, and then also will causes material impact to the healthy of hedging personnel.
Through literature search, retrieve the patent No. and be 200820073969.1 excretory system, schematic diagram is seen Fig. 1, it is characterized in that: drain collecting vessel at the survival capsule peripheral hardware, bung communicates with the indoor cinclides of survival capsule, and cinclides is provided with to open and covers; The indoor seat of survival capsule bottom is provided with chamber pot, and establish in the chamber pot collecting dung bag is housed, but this bag automatic sealing; Chamber pot mouth loam cake is a rumble seat, can freely open.This product need not driven by power, this product is safer more practical when mine disaster takes place, drawback is: one, should establish independently washroom in the Waiting space, if chamber pot is laid under the seat, foul smell must be filled the air whole confined space, and the air pollution that brings thus also will cause health threat to the hedging personnel; Its two, though the collecting dung bag for opening automatic sealing automatically, still needs manually the collecting dung bag is thrown away into the outer collecting vessel of survival capsule, the air insulated effect is not good relatively.
The related product of this utility model need not driven by power equally, and a need shake several following cranks before leaving the washroom can be easily clean with dirt removals such as sewage, ight soil, residues, can also remove the dirty gas of part.Through market survey and data-searching, domestic still do not have similar products and occur.
Summary of the invention
The purpose of this utility model provides a kind of dredge pump, relates in particular to the manual blowdown pump that confined spaces such as a kind of down-hole refuge or survival capsule use.This dredge pump comprise lead dirty threeway, let out dirty threeway, cylinder and the drive unit that links to each other with cylinder; Lead in the dirty threeway one and connect sewage inlet, residue two is logical to link to each other with cylinder; Let out in the dirty threeway one and connect outlet of sewer, residue two is logical to link to each other with cylinder; Piston is arranged in the cylinder; Drive unit comprises crank, cam, pull bar, and pull bar links to each other with piston, and the piston that hand crank drives in the cam linkage pull bar traction cylinder moves reciprocatingly along cam.Utilize piston motion to cause the variation of cylinder internal gas pressure to reach the effect of soil pick-up, blowdown thus.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further: present embodiment is only done the interpretation effect for the preferred embodiment of this utility model, does not limit the foundation of feature.
Shown in Fig. 2 and 3, this embodiment comprise lead dirty threeway, let out dirty threeway, drive unit that cylinder 2 and cylinder 2 are outer.Piston 3 is arranged in the cylinder 2, and the piston 3 in drive unit and the cylinder connects and drives reciprocating motion of the pistons.
Lead in the dirty threeway one and connect sewage inlet, remain two reduction of fractions to a common denominators and do not link to each other with the top of cylinder 2 sides, the bottom of side; Let out in the dirty threeway one and connect outlet of sewer, residue two logical with lead that residue two in the dirty threeway is logical to be symmetrically arranged in the top of cylinder 2 sides, the bottom of side along the cylinder axis axis.The residue two of leading in the dirty threeway that links to each other with cylinder 2 is led to, is let out in the dirty threeway residue two and flap valve all is housed on logical, and flap valve is open circuit towards the outlet of sewer direction.Piston 3 is embedded with piston packing 4 with cylinder 2 contacts site.
Drive unit comprises cam 10, shaft end ring 11, flat key 12, reducer 13, crank 14, pull bar composition.Be connected bearing pin 8, roller 9 between cam 10 and the pull bar in addition in order to connect.
Cylinder 2 is made up of cylinder body and cylinder cap 6, and pull bar and cylinder cap 6 contacts site also have pull bar sealing ring 7, cylinder cap sealing ring 5.
Its work of this embodiment specifically is achieved in that when shaking crank 14, by reducer 13 deceleration force amplifiers, makes cam 10 rotate, and the rotation of cam 10 has promoted the reciprocating motion of pull bar.
When piston 3 during toward right motion, its left side volume space increases, and forms parital vacuum, and upper left side flap valve 1-1 is subjected to the effect of inlet pressure and in-cylinder pressure difference and opens down, lower-left side flap valve 1-2 is subjected to closing under outlet pressure and the effect of in-cylinder pressure difference, and sewage charges into cylinder 2 leftward space; Simultaneously, the pull bar rightward space by compression, pressure increases, under the pressure differential effect, upper right side flap valve 1-3 closes, lower right side flap valve 1-4 opens, then sewage is forced out in the cylinder of right side.
When piston 3 during toward left movement, flap valve 1-2,1-3 open, and flap valve 1-1,1-4 close, and sewage is in inlet charges into cylinder 2 right side cylinders, and simultaneously, the sewage in the cylinder of left side is forced out.Like this iterative motion, thus reach the effect of soil pick-up blowdown.
This utility model is simple in structure, and air insulated is effective, and cost is low, and the actual application value height is easy to utilize.
