Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, biogas residue extractor for biogas digesters of the present utility model, comprises discharge nozzle 3, operating stick 2, piston link span, piston, reverse checkvalve and piston leg 9.
Discharge nozzle bottom terminal ends is closed, and discharge nozzle bottom sidepiece offers opening for feed 31.Discharge nozzle is straight tube, is convenient to piston and operating stick moves up and down in discharge nozzle.By opening for feed is opened in sidepiece by discharge nozzle bottom end closure, piston is avoided to deviate from discharge nozzle bottom and enter in methane-generating pit.
The cross-sectional diameter of operating stick is less than discharge nozzle internal diameter, and make to be provided with certain space between operating stick and discharge nozzle, not only convenient operation bar is up and down in discharge nozzle, and when being convenient to take out slag, natural pond slag flows to outside operating stick and between discharge nozzle simultaneously.
Piston link span top is fixedly connected on operating stick, is fixedly connected on piston upper surface bottom piston link span.Not only be convenient to be fixedly connected with operating stick and piston by arranging piston link span, and be convenient between operating stick and piston, flow out certain space movable and natural pond slag flowing for reverse checkvalve.
The external diameter of piston and the internal diameter of discharge nozzle suitable, when making piston movable in discharge nozzle, produce negative pressure in discharge nozzle bottom, thus extract the natural pond slag in methane-generating pit out.Its centre is provided with material hole.When operating stick drives piston to press down, natural pond slag flows to above piston by material hole, when being convenient to twitch piston, takes natural pond slag out of.
Reverse checkvalve is arranged on the material hole of piston.Reverse checkvalve comprises valve block 11 and centibar 10.Valve block center is provided with through hole and is socketed on outside centibar by this through hole.When piston presses down in discharge nozzle, natural pond slag pushes away valve block, valve block centrally on move, and then open material hole; When taking out on piston is in discharge nozzle, natural pond slag presses down valve block, and valve block centrally bar moves down, and then closes material hole.Valve block is all equal reaching in the process of pass the resistance of natural pond slag, so be unlikely to because resistance reduces and go on strike.Certainly, reverse checkvalve can also be door leaf formula reverse checkvalve or ball reverse checkvalve etc.
Piston leg is fixedly connected on piston base, and the height of piston leg is greater than the height of the opening for feed of discharge nozzle.Piston leg top is fixedly connected on piston diapire, and piston leg is vertical bar or tilting bar, and the vertical bar of piston leg is provided with one or more.When piston foot bottom termination contacts discharge nozzle bottom, piston leg top is also higher than opening for feed top, thus support high piston, piston is depressed into opening for feed that lowest part does not still reach discharge nozzle, thus it is stuck in opening for feed place to reduce piston side, thus when piston is extracted, reduce fracture and reduce blocking.
As shown in Figure 1, piston link span comprises sleeve 4, union lever 6 and locking bolt 5.Jacket casing is connected to operating stick bottom, and sleeve and operating stick are provided with corresponding lock hole and are locked by locking bolt.Union lever top is fixedly connected on sleeve, is fixedly connected with piston bottom union lever.To be socketed with operating stick to be connected by arranging sleeve, improve the strength of joint of piston link span and operating stick, reduce the fracture of piston link span, thus reduce the blocking to discharge nozzle.By the junction of locking bolt locking bushing and operating stick, operating stick not only can be avoided to rotate in sleeve and cause piston link span to come off, improve stability, and be convenient to piston link span dismounting and change.
As shown in Figure 1, union lever is provided with more than three and is uniformly distributed.Three union levers or four union levers are such as set.Connecting piston by arranging three union levers, the stress balance of piston can be improved, reduce and rupture between piston and union lever and come off, and then reducing the blocking to discharge nozzle.
As shown in Figure 1, locking bolt is bolt, and bolt runs through operating stick and sleeve by lock hole and passes through fastening nuts.By by bolt in conjunction with nut locking sleeve and operating stick, coming off of locking bolt can be reduced, and then the connection making piston and piston link span is more firm, thus reduces piston link span and come off, thus reduce blocking discharge nozzle.
As shown in Figure 1, piston comprises piston boit 8 and rubber ring 7.Piston boit outer side wall is provided with concentric(al) circles annular groove, and concentric(al) circles annular groove can be more than one, and rubber ring lock ring is in annular groove.The external diameter of rubber ring is greater than the external diameter of piston boit, and rubber ring is protruded from piston boit outer wall.By arranging piston boit, compare traditional piston length longer, better to the guidance quality of piston, reduce the diagonal distortion of piston, thus reduce fracture, reduce blocking, by arranging rubber ring, not only can play sealing function, and the elasticity between piston and discharge nozzle can be improved, thus the resistance reduced between discharge nozzle inwall, thus reduce piston fracture and reduce blocking discharge nozzle.In addition, rubber ring is changed more convenient, can reduce the wearing and tearing to piston entirety, improves work-ing life.
As shown in Figure 1, piston leg comprises the equal support bar of more than three length.Supporting bar top to distribute along circle with same intervals and is fixedly connected on piston diapire, and support bar bottom is mutually permanently connected, and forms skeleton with cone conformation shape, and down, e.g., three support bars then form triprismo skeleton to cone point, and four support bars then form rectangular pyramid skeleton.By the support bar lower end of piston leg is mutually permanently connected, cone point is formed in feet bottom, not only can padded piston, avoid seizure of piston in discharge nozzle opening for feed, and can broken hole and fragmentation on the slag of natural pond, be piston open circuit, thus reduce natural pond slag to the resistance of piston, and then reduce piston and the flexural deformation of piston leg, and then reduce piston fracture and reduce blocking discharge nozzle.
As shown in Figure 1, operating stick top is provided with handle 1.Be convenient to hold and rotate by arranging handle, thus convenient operation operating stick.
