Description
Technical field
The utility model relates to a kind of vacuum pump, specifically be meant a kind of for drawing the biogas fertilizer in the biomass pool, and on haulage device employed biogas vacuum pump.
Background technique
At present, chemical fertilizer is used in China farmland mostly, and chemical fertilizer can make soil structure worsen, thereby the harm people's is healthy.Along with the raising of people's lives, promote green agriculture, nuisanceless grain is extremely urgent, and use the biogas fertilizer, then be the best approach of plantation green cereal.Biogas fertilizer is to handle debirs in the marsh gas fermentation processes, for example produce when the excrement of fowl poultry kind, green grass class and distillery waste etc., people usually are designed to biomass pool arch for ease of producing biogas, its outlet is dark and little, and general utensil is difficult to the biogas fertilizer in it is extracted.Built many biomass pools the eighties in south, gave it up one after another again afterwards, and this and not corresponding absorption haulage device have much relations; For this reason, many in recent years producers have released the biogas transport vehicle, the vacuum pump of its use roughly has two kinds, a kind of is that chemical pump and original automobile are inhaled excrement, soil pick-up pump, and these pumps not only cost an arm and a leg, and do not have performance antirust, explosion-proof, anticracking, rare thick the differing of methane liquid, the natural pond solid impurity particle is bigger, also contains under the situations such as methane, carbon dioxide in the biogas, and it is not suitable for the biogas operation; Another kind is for drawing the custom-designed vacuum pump of biogas fertilizer, it comprises that a stator and one are arranged in this stator cylindrical form interior surface and the axis that departs from this cylindrical form interior surface is made eccentric rotor in relative rotation, this stator has a suction port and an air outlet, described rotor has four along its groove of axially offering and place in this groove and the blade that is slidingly matched with it, when described rotor rotates, described blade cooperates along the slip of stator cylindrical form interior surface and with this internal surface hermetic seal under action of centrifugal force, contiguous suction port place also is provided with the muscle of the strip that is used to dispel the heat and strengthens on the housing of described stator, has an entity lug that roughly is 90 * 50 millimeters above the air outlet; The vacuum pump of this spline structure, on the one hand, because the heat radiation of pump is to distribute by the conduction of the muscle on the stator case, and the entity lug of top, air outlet has stoped distributing of heat, totally unfavorable to dispelling the heat, but also increased the weight of the weight of stator case, on the other hand, because rotor is an ironcasting, the groove in the rotor is corrosion easily after using the short period, makes blade must not slide under centrifugal action, air-breathing working room is hindered, make effectively to form vacuum, but also make pump housing blast cracking, thereby cause personal injury and equipment accident.In addition because groove is darker, make rotor intensity a little less than.
The model utility content
The technical problems to be solved in the utility model provides a kind of biogas vacuum pump, and the groove in its rotor can corrosion in when work, and the pump housing is explosion-proof, anti crack performance is good thereby make, and is safe and reliable when guaranteeing work, and the radiating effect of the pump housing is good.
For solving the problems of the technologies described above, a kind of biogas vacuum pump that the utility model adopted, comprise that a stator and one are arranged in this stator cylindrical form interior surface and the axis that departs from this cylindrical form interior surface is made eccentric rotor in relative rotation, this stator has at least one suction port and at least one air outlet, described rotor has at least one along its groove of axially offering and place in this groove and the blade that is slidingly matched with it, when described rotor rotates, described blade cooperates along the cylindrical form interior surface slip of stator and with this internal surface hermetic seal under action of centrifugal force, contiguous suction port place also is provided with the muscle of the strip that is used to dispel the heat and strengthens on the housing of described stator, described muscle extends to place, described air outlet from the suction port of adjacent stator, and described eccentric rotor is a macromolecular material spare.
Described epitrochanterian groove has four, and described eccentric rotor is a glass fiber reinforced plastic spare.
After adopting such structure, on the one hand because eccentric rotor is a macromolecular material spare, eradicated the antirust problem of the groove in the rotor and increased vacuum efficiency, played effect explosion-proof, anticracking, and can reach the slow-speed of revolution, low noise, high vacuum, high efficiency requirement; On the other hand, described strip muscle extends to place, described air outlet from the suction port of adjacent stator, compares with existing pump like this, removed the entity lug of top, air outlet,, thereby improved radiating condition directly the muscle top, air outlet of extending, and alleviated weight, reduced cost of production.
It axially can offer at least one through slot described rotor upper edge.Such structure can alleviate the weight of rotor.
Described through slot is preferably four, and is provided with stiffening rib in each through slot.The cross section of described stiffening rib is preferably the T font.Adopt such structure, the weight of rotor is not only lighter, can save more raw materials, and intensity is higher, thereby not fragile when work.
As a kind of improvement of the present utility model, its central axis of described rotor upper edge offers an axis hole that is used to connect transmission shaft, and the distance between the bottom surface of described groove and the described axis hole internal surface is 5.5～6.5 millimeters.Described axis hole is a splined hole.Adopt such structure, not only rotor processing is easy, and the intensity of rotor is higher, longer service life.
