Abstract
The utility model provides a biogas digester scuttle sealing cover, which comprises a scuttle, a water-maintaining ring arranged on the scuttle and a sealing cover; the scuttle is of an oblong or rectangular shape with unequal horizontal and longitudinal axles; the cover body below the scuttle is also arranged into an oblong or rectangular shape with unequal horizontal and longitudinal axles, while the horizontal and longitudinal axles have a bigger size than the scuttle, and are connected with a cross rod on the water-maintaining ring. The utility model is characterized in that the water-maintaining ring and the opening are designed into corresponding oblong or rectangular shape with unequal horizontal and longitudinal axles; with the differences among the cover body, water-maintaining ring and the long and short axles of the scuttle, the cover body is vertically positioned in the digester, then horizontally turned 90 degrees to cover the scuttle from top to bottom, and fastened to the cross rod through a connecting bar with a spring; with the expansion pressure in the biogas digester, the seal requirement can be fully met. The cover can be slightly removed by turning and erecting the cover body.
Description
Technical field
The utility model relates to a kind of sealing cover, especially a kind of skylight opening sealing cover that is used on the methane-generating pit.
Background technology
In resource and energy today comparatively in short supply, for solving the life fuel problem in vast rural area, all can gather materials on the spot wideling popularize application in various places, do not waste resource, do not influence the eubiosis, do not take up an area of and convenient and healthy methane-generating pit.This methane-generating pit is made of skylight opening and the sealing cover that Chi Tiji is located at Chi Tishang, and being provided with of skylight opening and sealing cover mainly is for the ease of managing and change the waste material in the methane-generating pit, to improve gas production rate.Traditional methane-generating pit sealing cover adopts cement cover board gravity Sealing Method and flange, bolted Sealing Method more, and complex structure is not only installed, operation is cumbersome, and its sealing property is not good.Other is such as easy sealing covers such as flat board lids, and its sealing property is more undesirable.Therefore, be necessary right
Prior art is improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, easy to operate, good seal performance, the methane-generating pit skylight opening sealing cover that reliability is high.
The utility model is realized by following technical proposal: a kind of methane-generating pit skylight opening sealing cover, it comprises skylight opening and cycle of water conserving and sealing cover provided thereon, wherein skylight opening is set to horizontal stroke, unequal ellipse of the longitudinal axis or rectangle, the lid that is positioned at the skylight opening below also is set to horizontal stroke, unequal ellipse of the longitudinal axis or rectangle, and the horizontal stroke of lid, the longitudinal axis is all greater than skylight opening, and link to each other at cycle of water conserving load bar suitable for reading with load by the connecting rod on it, it is characterized in that cycle of water conserving and on mouthful be made as the horizontal stroke that adapts with skylight opening, unequal ellipse of the longitudinal axis or rectangle.
The described connecting rod that links to each other with sealing cover is provided with spring, is used for adjusting automatically the elasticity of sealing cover.
Be provided with the sealing-ring of forming by rubber or clay or pitch between described skylight opening and the lid.
Described skylight opening wall is made as up-small and down-big awl wall, so that manufacture.
Described cycle of water conserving wall is made as up-small and down-big awl wall, so that manufacture.
The utility model compared with prior art has following advantage and effect: the differentiation of the long and short axle by skylight opening, lid and cycle of water conserving, make long and short axle all can utilize the difference of long and short axle greater than the lid of skylight opening, revolve and turn 90 degrees vertical plane and place in the pond, after horizontally rotating 90 degree down tilts again, seal skylight opening from bottom to top, connecting rod by the band spring is fixed on the load bar, relend the swelling pressure that help in the methane-generating pit, can satisfy seal request fully, when uncapping, as long as take out nut and load bar, light hub cap body also makes it upright, can conveniently get lid.Real is a kind of simple in structure, use, easy to operate, the methane-generating pit sealing cover that stopping property is splendid.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan structure figure of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, is not limited in this but hold within the utility model.
Among the figure, the oval skylight opening 1 on fen top is made as up-small and down-big awl wall, whole lid is installed in the wall is oval-shaped sealing cover 4, lower edge 2 upper surfaces of ovaloid seal lid 4 link to each other with the inboard of skylight opening 1 by sealing-ring 3, ovaloid seal lid 4 is fixed on the load bar 9 by the connecting rod on it 5 and spring 6, packing ring 7, nut 8, the top of sealing cover 4 is oval cycle of water conserving 11, and the cycle of water conserving wall is made as up-small and down-big awl wall, and cycle of water conserving 10 tops are oval port 10.
Claims (5)
1, a kind of methane-generating pit skylight opening sealing cover, it comprises skylight opening and cycle of water conserving and sealing cover provided thereon, wherein skylight opening is set to horizontal stroke, the unequal ellipse of the longitudinal axis or rectangle, the lid that is positioned at the skylight opening below also is set to horizontal stroke, the unequal ellipse of the longitudinal axis or rectangle, and the horizontal stroke of lid, the longitudinal axis are all greater than skylight opening, and link to each other at cycle of water conserving load bar suitable for reading with load by the connecting rod on it, it is characterized in that cycle of water conserving and on mouthful be made as unequal ellipse of horizontal stroke, the longitudinal axis or the rectangle that adapts with skylight opening.
