Description
Technical field
The present invention relates to a kind of membrane pump with pneumatic drive.
Background technique
The biomass pool latest national standards issued for 2002 comprises 5 kinds of pond types, i.e. water pressing cylinder methane-generating pit, separation float cover type biogas generating pit, meandering distribution methane-generating pit, prefabricated block (cylindrical shape) biomass pool and elliposoidal biomass pool; Cylinder methane-generating pit had both been pipeline type biomass pool, and fermentation raw material enters fermentation in fermentation pipeline and produces biogas, and in fermentation pipeline inner accumulated, easily caused the obstruction of fermentation pipeline; If obstructive position is comparatively dark, usually adopt all foreign material removed in fermentation pipeline, more logical by body of rod stamp.
Animal wastes are fermented the natural pond liquid made, and tasteless and fertilizer efficiency after fermentation after fermentation is more than 10 times of general chemistry synthetic fertilizer; Water quality characteristic is very easily absorbed by plants, and can not as chemical fertilizer, and natural pond liquid use amount too much also can not burn seedling, as the first-selected fertilizer of green ecological plantation, natural pond liquid has: effect of expelling parasite, desinsection, and the fatal rate of larva and worm's ovum is more than 90%, belongs to green biological insecticidal agent; Natural pond liquid in use, is held bad consumption and also can not be caused and burn seedling phenomenon, and this is also one of incomparable place of general chemistry synthetic fertilizer.
The marsh gas fermenting system that the present invention adopts, employing be pipeline type fermentation system, it can avoid blocking completely, and mode manually can promote being uniformly distributed of fermentation raw material, and it is convenient to remove natural pond slag.
According to Henry law, in natural situation: P=(Po2+PH2O) X0.209, the saturation ratio of often liter of oxygen in water is (8-10mg/L)=100%; Atmospheric pressure is lower, and dissolved oxygen in water degree is lower.Overcast and rainy sultry moist sky, due to reasons such as air pressure and temperature reductions, can cause dissolved oxygen in water to overflow fast the water surface; And the main source of oxygen in water is the photosynthesis of plankton and water plants, the oxygen that they produce when illumination accounts for about 70% of water oxygen level, and the oxygen dissolved in air in water only accounts for about 30% of water oxygen level.The consumption of water fish class animal and water plants only accounts for about 30% of total chlorine consumption, all the other oxygen can be overflowed under the external factor such as air pressure, temperature change effect in air, this also can be interpreted as what daytime fish to produce the more waters of oxygen air port plankton under downstream and water plants movable, and to evening because phytoplankton and water plants will consume a large amount of oxygen and cause this waters anoxic, so the relative oxygen-rich area that evening, fish will swim over to upstream uptake looses.From daybreak, along with the enhancing gradually at sunshine, the oxygen that water plants produces under photosynthesis gets more and more, and fish starts again to move from the oxygen-rich area in the downward air port of uptake, and mobility and ability of looking for food also strengthen gradually.
Claimant finds a kind of membrane pump with pneumatic drive (patent No.: 2012101329572) of claimant Anhui Lechang Pneumatic Fluid Equipment Technology Co., Ltd. application by retrieval, it discloses the product similar with machine for adding oxygen of the present invention, its air pressure adopting source of the gas to produce as power in order to drive the bilateral reciprocation of diaphragm; Poppet shaft (being equivalent to regulation and control axle of the present invention) is socketed on centre valve in-core by it, and spool two ends, center are provided with step chamber, and the interior edge face of end spool is provided with secondary ring-shaped step; The complex structure of center spool and end spool, adds cost of production.
