Abstract
The invention discloses an axial flow pump. The axial flow pump comprises a shell, an impeller chamber in the shell, and an impeller arranged in the impeller chamber, wherein the impeller is connected with a motor through a rotating shaft, a water inlet is formed in the lower end of the impeller chamber, and a water outlet is formed in the upper side of the impeller chamber. The axial flow pump is characterized in that no guide vane body is arranged, and the impeller is a spiral closed impeller. The number of vanes of the impeller is two. The rotating shaft and the motor are respectively connected with a pagoda-shaped belt pulley through a triangular belt, and the two pagoda-shaped belt pulleys are arranged in the opposite directions. The axial flow pump has the advantages that the axial flow pump is suitable for being used in biogas slurry containing a large number of particles and gas in a circulating mode, the axial flow pump can not be easily blocked, the speed can be regulated, backflow can be achieved, and marsh gas production rate can be obvious increased.
Description
Technical field
The present invention relates to axial-flow pump technology, specifically a kind of natural pond liquid axial-flow pump that is applied to biogas preparation field.
Background technique
Its structure of common axial-flow pump comprises the blade wheel chamber in housing, housing, is provided with diffuser and impeller in blade wheel chamber, and diffuser, impeller are connected with motor by rotating shaft, and the lower end of blade wheel chamber is provided with water intake, and upside is provided with water outlet.The axial-flow pump of this structure, when work, the flow direction of liquid is from water intake to water outlet, mobile direction is fixed, and can not instead flow; And can only carry clear water or slight sewage, when sewage endoparticle thing is more, larger, easily stop up, not be suitable for the natural pond liquid that produces biogas.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, be suitable for containing high particle, the axial-flow pump that has gas to recycle in interior natural pond liquid and provide a kind of, this axial-flow pump is difficult for stopping up also adjustable speed, can instead flow, and can obviously improve production rate of methane.
The technological scheme that realizes the object of the invention is:
A kind of axial-flow pump, comprises blade wheel chamber in housing, housing, is arranged on the impeller in blade wheel chamber, and impeller is connected with motor by rotating shaft, the lower end of blade wheel chamber is provided with water intake, upside is provided with water outlet, it is characterized in that: do not establish diffuser, described impeller is spiral double shrouded wheel.
The blade quantity of described impeller is 2.
Described rotating shaft, motor are respectively equipped with the pagoda belt pulley connecting by v belt, and two pagoda belt pulleys are oppositely installed each other.
Described rotating shaft and bearing support are equipped, and the rotating shaft cover in bearing support has seal ring, and in rotating shaft, cover has two dish bearings, and bearing support is fixed on housing.
Advantage of the present invention is, is suitable for containing high particle, has gas to recycle in interior natural pond liquid, and this axial-flow pump is difficult for also governing speed easily of obstruction, can instead flow, and can obviously improve production rate of methane.This sealing structure circle ring blade wheel chamber to, moving-coil bearing to, the spring of seal moved ring does not contact natural pond liquid, is not subject to natural pond corrosion, more durable, long service life.

Embodiment
Below in conjunction with drawings and Examples, content of the present invention is further described, but is not limitation of the invention.
Embodiment:
With reference to Fig. 1, a kind of axial-flow pump, comprise blade wheel chamber in housing 1, housing 1, be arranged on the impeller 2 in blade wheel chamber, impeller 2 is connected with motor 12 by rotating shaft 8, the lower end of blade wheel chamber is provided with water intake 14, upside is provided with water outlet 15, and this axial-flow pump is not established diffuser, and described impeller 2 is spiral double shrouded wheel.
As shown in Figure 2, the blade quantity of described impeller 2 is 2, is the first blade 2-1 and the second blade 2-2.
Described rotating shaft 8, motor 12 are respectively equipped with 7, two the pagoda belt pulleys 7 of pagoda belt pulley that connect by v belt 13 and oppositely install each other.By adjusting the upper-lower position of v belt at pagoda belt pulley, can regulate easily the rotating speed of impeller.
Described rotating shaft 8 is equipped with bearing support 5, and the rotating shaft cover in bearing support 5 has seal ring 3, and in rotating shaft 8, cover has two dish bearings 4, and bearing support 5 is fixed on housing 1.
Particularly, impeller 2 use nuts 9 fasten in the lower end of axle 8, and the top of impeller 2 is overlapped and had seal ring 3 in the rotating shaft 8 of the inside of bearing support 5, and on the axle of seal ring 3, cover has two dish bearings 4, fasten 5 li of bearing supports by bearing cap 6 and screw rod 10, bearing support 5 fastens on housing 1 by screw 11.
When operation, starting electrical machinery 12, rotates impeller 2, and natural pond liquid is drawn into from water intake 14, flow out from water outlet 15, and when motor 12 reversed operations, natural pond liquid reverse flow, natural pond liquid is drawn into from water outlet 15, flows out from water intake 14.
This axial-flow pump is owing to having adopted spiral helicine double shrouded wheel, and blade quantity only has two, therefore can make that impeller reversion is contrary draws water, and can make biogas fermentation normally carry out for a long time, has anti-blocking effect, and stirring action, effectively improves biogas output.
