Abstract
A pure straw fermentation biogas digester mainly comprises a tank body fermentation chamber consisting of an upper semi-spherical body and a lower semi-spherical body sealed with each other; a hydraulic room arranged on the side surface of the upper semi-spherical body; and a water sealing chamber arranged on the top of the upper semi-spherical body, wherein a floating cover can seal the tank body fermentation chamber when the water sealing chamber is filled with water. By adopting the integrated design of floating cover type and hydraulic type structures, the biogas digester can achieve complementation in function and structure, and can achieve uniform and stable biogas generation and fast and convenient use by adding straw as the fermented material. The biogas digester can achieve standardized, technical and programmed production, is subjected to normalized quality inspection before leaving the factory, and is installed in the splicing manner in the construction site. The product has passed the examination of the biogas product quality test center of the department of agriculture and the national building material test center, so that the biogas digester can meet the actual requirement for construction of economical society and new rural construction and can substitute for the prior reinforced concrete biogas digester and the rising fiber reinforced plastic biogas digester.
Description
[technical field]
The present invention relates to a kind of cover-floating type, hydrostatic, can utilize the preparation technology of pure stalk as the methane-generating pit of fermented product.
[background technology]
Stalk is used for the fermented product of methane-generating pit, and is very common.General " one deck ight soil, one deck stalk, one deck river silt (inoculum), one deck stalk, one deck ight soil " mode that adopts is mixed use with stalk with ight soil, river silt etc.But with pure stalk as fermented product, domestic application success several families are only arranged.At present, all stalk fermentation is used, and all faces two hang-ups: one, stalk must shred, stack retting, only shred the stalk of a metric ton, just need suitable cost of labor or transportation cost; Two, the stalk fermentation thing is all very difficult when discharging, and this problem is extremely whole to the beginning, is all perplexing the practical application of stalk fermentation.The stalk that pure straw fermentation biogas digester of the present invention uses can shred, and after the use composite bacteria is handled stalk, directly puts into fermentation vat and gets final product; Discharging is then quite convenient, opens floating cover, in 2 hours, can discharging finish.
[summary of the invention]
The purpose of this invention is to provide a kind of simple in structurely, with low cost, be fit to industrialized mass production, on-the-spot splicing is installed, available pure stalk is as methane-generating pit fermented product, multi-functional.
Technical solution of the present invention is as follows:
Become water ladle shape curved body by hemisphere face shape water nozzle with second spherical surface body two part combined preparation.Make pond body sweathouse by first spherical surface body and the sealing of second spherical surface body.Open a round mouth at the top of first spherical surface body, be used to install seal in the tubular, interior seal and pond body sweathouse link; The outside of seal in outer seal is installed in, interior seal and outer seal constitute between water seal; In between the water seal in the floating cover of drum shape back-off is placed between seal and the outer seal.The tubular water pressure house is erect a side that is placed on first spherical surface body, and water pressure house and pond body sweathouse link, and the position of water pressure house is corresponding with the position and the size of hemisphere face shape water nozzle with size; Feed-pipe is installed in the symmetrical opposite side in position of first spherical surface body and water pressure house, and feed-pipe and pond body sweathouse link.
Advantage of the present invention is as follows:
1, because what adopt is the technology of overall package, and the pond outer wall has formed a seamless integral body, good airproof performance, stressed evenly, anti-folding, tensile property are superior; It is very convenient to construct, and reaches 30 years work-ing life.
2, owing to adopted the design of floating cover structure, the feeding intake of methane-generating pit, big discharging, all very convenient.
3, owing to adopted cover-floating type and hydraulic type structure to combine, form complementation, user's usefulness gas is uniform and stable.
4, methane-generating pit designs for integrated structure, and pond body structure compactness, globality be strong, it is little to take up an area of, and can make full use of the supporting capacity of soil, can bear more bigger pressure in the body of pond, labor and material saving, and cost is lower.
5, the feed-pipe that outwards tiltedly stretches out of pond body is convenient to being connected of sewage draining exit of feed-pipe and lavatory or pigsty.

Comprise among the figure: 1-3, water ladle shape curved body 2, hemisphere face shape water nozzle 2-1, second spherical surface body 2-2, pond body sweathouse 3, tubular water pressure house 4, tubular feed-pipe 5, the floating cover 6 of drum shape between first spherical surface body 1, the interior seal 1-1 of tubular, the outer seal 1-2 of tubular, water seal.
[embodiment]
The preparation technology of pure straw fermentation biogas digester of the present invention is as follows:
1) becomes water ladle shape curved body 2 by hemisphere face shape water nozzle 2-1 with second spherical surface body 2-2 combined preparation;
2) make pond body sweathouse 3 by first spherical surface body 1 and the two sealing of second spherical surface body 2-2;
3) open a round mouth at the top of first spherical surface body 1, be used to install seal 1-1 in the tubular, seal 1-1 and pond body sweathouse 3 link in the tubular;
4) the outer seal 1-2 of tubular is installed in the outside of seal 1-1 in the tubular, and the outer seal 1-2 of seal 1-1 and tubular constitutes 1-3 between water seal in the tubular;
5) the floating cover of drum shape 6 back-offs are placed in the tubular between the water seal between the seal 1-1 and the outer seal 1-2 of tubular in the 1-3, after 1-3 adds water between water seal, and 6 effects of playing seal closure of the floating cover of drum shape;
6) tubular water pressure house 4 is erect a side that is placed on first spherical surface body 1, and tubular water pressure house 4 links with pond body sweathouse 3, and the position of tubular water pressure house 4 is corresponding with position and the size of hemisphere face shape water nozzle 2-1 with size;
7) tubular feed-pipe 5 is tiltedly stretched the symmetrical opposite side in position that is installed in first spherical surface body 1 and tubular water pressure house 4, and tubular feed-pipe 5 links with pond body sweathouse 3.
Methane-generating pit of the present invention because the design of having adopted cover-floating type and hydraulic type structure to combine, on function and structure, form complementary, the user uniform and stable with gas, use efficient and convenient.Methane-generating pit of the present invention can be used as pure straw fermentation biogas digester fully and uses.Stalk can shred, and after the use composite bacteria is handled stalk, directly puts into fermentation vat and gets final product; Discharging is then quite convenient, opens floating cover, can discharging finish in 2 hours; At ordinary times little discharging and routine maintenance can realize by water pressure house.
