Description
Technical field
The invention belongs to agricultural machinery engineering technical field, relate to a kind of feeding unit of methane-generating pit.
Background technology
Existing common methane tank feeding device is by opening for feed, and because volume is less, be called opening for feed and feed-pipe composition, opening for feed and fermenting between main pond is connected by feed-pipe, and opening for feed plane is equal with biogas fermentation main pond plane, is embedded in underground.With during gas along with feed liquid liquid level declines naturally, the raw material being deposited in opening for feed enters into the main pond of fermentation by feed-pipe gravity flow, completes charging.The shortcoming of this device is: when fermentation raw material is lighter stalk fermentation raw material, by the impact of the biogas pressure stored in methane-generating pit, float over liquid level, raw material is difficult to gravity flow and enters into fermentation vat.
Utility model content
The utility model will in order to solve the problems of the technologies described above, and feeding unit is made up of heavy caliber feed tank, overstriking feed-pipe, natural pond liquid pump around circuit pipeline, sump pump,
In order to solve the problems of the technologies described above, the utility model provides a kind of methane-generating pit automatic cycling feeding apparatus, comprise methane-generating pit, feed tank, feed tank is connected with methane-generating pit by feed-pipe, methane-generating pit top is provided with return line and sump pump, and sump pump is arranged at the connectivity part of return line and methane-generating pit, and return line connects methane-generating pit and feed tank.During charging, stalk fermentation raw material pours feed tank into, connect sump pump motor switch, the natural pond liquid fermented in main pond enters feed tank by pump around circuit pipe, initial stage, feed-pipe is automatically blocked by stalk fermentation raw material and seals the mouth of pipe, natural pond liquid is accumulated in feed tank, liquid level rises, along with constantly pumping into of natural pond liquid, the liquid level of feed tank can constantly increase, the natural pond liquid liquid level fermented in main pond can constantly decline, when the pressure of feed tank is greater than the pressure in main pond of fermenting, be rushed to open by the charging mouth of pipe that raw material blocking is closed, raw material can automatically enter main pond of fermenting together with the liquid of natural pond, complete charging.So move in circles, stalk fermentation raw material can enter methane-generating pit like a cork, and is fully mixed.
As the further improvement to the technical program, described feed tank is built on the ground, exceeds methane-generating pit plane 800mm to 1000mm.The long 1000mm of feed tank, wide 1000mm, dark 900mm, net volume reaches more than 0.9 cubic metre.By strengthening feed tank size, headroom volume being increased, being convenient to hold bulk stalk fermentation raw material; Feed tank is built on the ground, exceeds methane-generating pit plane 800-1000mm, is convenient to improve charging liquid level and the pressure difference of fermentation main pond liquid level, makes raw material easily charging under the effect of the pressure.
As the further improvement to the technical program, described feed tube diameter is 500mm, the overstriking of feed-pipe caliber, is convenient to the input speed accelerating stalk solid feed, prevents caliber too little and blocked.
As the further improvement to the technical program, described return line uses the pvc pipe of diameter 32mm.Newly-increased natural pond liquid pump around circuit pipe and sump pump, realize the reflux cycle of natural pond liquid between the main pond of fermentation and feed tank, drives entering and abundant mixing between main pond of raw material.
As the further improvement to the technical program, described methane-generating pit bottom is provided with discharge port, and discharge outlet is provided with filtering net.
As the further improvement to the technical program, described methane-generating pit bottom is provided with whipping appts, and whipping appts comprises screw-blade, screw-blade protective shell, agitator motor.
As the further improvement to the technical program, described methane-generating pit wall is provided with thermal insulation layer, impervious barrier.
Compared with prior art, the beneficial effects of the utility model are: expanded biogas development space.Owing to solving stalk raw materials charging difficulty and the difficult problem of mixing, breach the restriction that straw from village class waste is difficult to become biogas fermentation material.For a long time, the development of biogas industry is only confined to based on aquaculture, and with the material of the easy charging of feces of livestock and poultry small-particle solid, liquid mixture for fermentation raw material, fermentation raw material is single, and development space is limited.Particularly along with livestock and poultry intensivization development, the radix of casual household's cultivation reduces gradually, adds methane-generating pit that upper part builds owing to stopping using by the impact of aquaculture market conditions lacks raw material, all constrains the tremendous development of biogas cause.There is a large amount of stalk raw materials in rural area, but because of this kind of raw material weight light, enlarged volume, original methane tank feeding device is difficult to be suitable for, and also float over liquid level be difficult to mix with feed liquid in pond even if enter methane-generating pit, aerogenesis effect is bad, fails to be widely used.This contrive equipment, adopts natural pond liquid circulation automatic feed technology, and solve the problem that stalk raw materials charging is difficult and mixing is difficult, respond well by application attestation in practice, the light charging of stalk fermentation raw material, mixes, and factor of created gase improves.The application of this contrive equipment will widen the development space of biogas industry greatly, improves the recycling level of countryside wastes, for the Sustainable development realizing agricultural will play crucial effect.Solve the problem of straw from village class waste pollution environment.There is a large amount of stalk waste in rural area, is scattered in field, farmyard corner stack retting, fails Collection utilization, contaminate environment.For my fire combustion edible mushrooms base, district, various mushroom annual production reaches more than 4000 ton, the agricultural wastes environmental pollution problems such as its tankage become increasingly conspicuous, about 1,200 ten thousand bags, bacterium bud is discarded in annual generation, discarded tankage 160 tons, bulk deposition is degenerated at factory building periphery, produce the toxic gases such as hydrogen sulfide, and grow mosquitos and flies, bacterium, virus etc., cause hygienic safety hidden danger, to the production of enterprise, the living environment of periphery villager brings great impact, hinder expanded reproduction and the Sustainable development of industry self, become the bottleneck problem of Edible Fungi Industry Development.This invention technology, solve the critical problem that stalk raw materials fails to be utilized, waste material is turned waste into wealth, waste materials is collected in anaerobic fermentation in airtight environment, and killed poisonous and harmful germ wherein, that has eradicated mosquitos and flies grows place, health looks improve, problem of environmental pollution is solved, and the biogas simultaneously produced, the fertile reproducible utilization in natural pond, facilitate the development of Eco-Agricultural Circular Economy.
