Abstract

The aim of the utility model is to provide a box type methane pool device which has a scientific and reasonable structure and convenient tapping and can produce methane on the ground, semi-ground and full-ground. The device consists of an outer box, an inner box, an air outlet pipe and a handle. The device is characterized in that the upper surface of the outer box is not sealed; the undersurface of the inner box is not sealed; the inner box is positioned in the outer box; the cross section of the inner box is polygonal or circular; and the inner box is lifted out only by the handle in tapping, thereby conveniently cleaning out the fermented slag in the box.

Description

A kind of box methane-generating pit device

Technical field:

The utility model relates to a kind of biogas generating device, definite a kind of box methane-generating pit device of saying so.

Background technology:

Development biogas cause be that country promotion energy-saving and emission-reduction an indispensable part, particularly rural area utilize methane-generating pit to produce the biogas most important thing especially, but the methane-generating pit in rural area is not also popularized.Mainly being that existing methane pool exists a lot of defectives, is to be one of material wherein with cement as the existing methane pool majority, corrodes cement easily and contain a large amount of hydrogen sulfide in the methane-generating pit, causes cement to come off, and causes the methane-generating pit seepage and loses heart; The existing methane pool relative aperture is less, and input and output material is very inconvenient.

Summary of the invention:

The purpose of this utility model is to provide a kind of scientific and reasonable for structure, slag tap conveniently, can be on the ground, half ground, full ground produces the box methane-generating pit device of biogas, the material of its use is difficult for being corroded, only need when slagging tap interior case to be proposed, just can easily the slag of sending out filial piety in the case be cleared up away by handle.Mainly be by the original whole totally-enclosed split type snap-fit design that changes into, change the liquid that utilizes in the methane-generating pit into by original artificial outside seal and seal voluntarily.

Technical solution of the present utility model:

The purpose of this utility model be to provide a kind of scientific and reasonable for structure, slag tap conveniently, can be on the ground, half ground, full ground produces the box methane-generating pit device of biogas, form by outer container, interior case, escape pipe, handle, it is characterized in that, do not bind above the described outer container, back cover not below the interior case, interior case places in the outer container, and its cross section is Polygons or circle, only need when slagging tap interior case to be proposed, just can easily the slag of sending out filial piety in the case be cleared up away by handle.

Embodiment

The utility model is a kind of box methane-generating pit device, is the outer container of box methane-generating pit as Fig. 1, is placed on its outer container on the ground or half ground (imbedding next one of ground), in the place that sun power shines.Put into the foreign material of easy generation biogas earlier in outer container inside, as pig manure, mashed grass, water etc., as Fig. 2 is interior case with box methane-generating pit, and interior case (5) is put into outer container (4), compresses as Fig. 3, cross about 10 days, foreign material and water will produce biogas, because the outer wall of interior case and the inwall of outer container be close to, so biogas can't leak outside, have only by emitting biogas in the escape pipe on the interior case (1), escape pipe (1) is inserted gas combustion apparatus can use.After with for some time, biogas can be fewer and feweri, when biogas is very faint by the time, illustrates that foreign material have fermented to finish.At this moment can pass through handle (2), handle (3) with interior case (5) proposition, the foreign material that outer container (4) is interior are cleaned out and are got final product.

Claims

1, a kind of box methane-generating pit device is made up of outer container (4), interior case (5), escape pipe (1), handle (2), handle (3), it is characterized in that, described outer container does not bind above (4), back cover not below the interior case (5), and interior case (5) places in the outer container (4).

2, a kind of box methane-generating pit device according to claim 1 is characterized in that, described outer container (4), its cross section of interior case (5) are Polygons.

3, a kind of box methane-generating pit device according to claim 1 is characterized in that, described outer container (4), its cross section of interior case (5) are circular.

4, a kind of box methane-generating pit device according to claim 1 is characterized in that, described outer container (4) can be formed by 1 to 4 layer.
