Abstract

The utility model discloses a quick-attach-detach biomass pool movable cover for composite materials, which comprises an annular pool cover base, and is characterized in that a convex column in the middle of the pool cover base is uniformly fixed with screws with screw rods, wherein the quantity of screws is even number, and the upper ends of the screw rods extend out of the convex column; the bottom end of the edge of the round pool cover is seated on the inner seat of the annular pool cover base; an O-shaped seal ring is arranged between an upper groove and a lower groove of the seal ring; an air guide pipe is fixed in the middle of the round pool cover; and a pool cover compressing device is fixed above the round pool cover and comprises a transverse lever, a transverse lever lantern ring and a plurality of wedge blocks or comprises a pressing lever. The round pool cover is tightly pressed on the annular pool cover base and dead-presses the seal ring so as to prevent biogas leakage from the edges, and biogas can only be discharged from the air guide pipe, thus thoroughly solving the problem that the original biomass pool have water loss and biogas leakage by taking yellow mud as sealing medium when in changing materials. The biomass pool movable cover for composite materials has the advantages of good sealing performance, no leakage, quick attachment and detachment, light weight, and convenient installation.

Description

Matrix material fast assembling-disassembling methane-generating pit removable cover

Technical field

The utility model relates to methane-generating pit equipment, especially relates to a kind of matrix material fast assembling-disassembling methane-generating pit removable cover.

Background technology

At present, domestic methane-generating pit for farm household removable cover is to form with cement, sand and a small amount of reinforcing bar cast mostly, and it is shaped as truncated rectangular pyramids shape.The big end of removable cover is following during installation, and small end is put into by the square orifice diagonal lines of methane-generating pit last, ajusts again.Because the four rib prostomum degree and the removable cover of methane-generating pit mouth almost match, between methane-generating pit mouth and removable cover, coat yellow mud sealing (doing sealing medium with yellow mud is in order to uncap next time conveniently) during capping, in the methane tank gas production process, the methane-generating pit internal pressure progressively strengthens, the anti-cone of removable cover is just pressed tight more more, thereby keeps biogas not leak.

Add up according to many data, sealing medium between methane-generating pit mouth and the removable cover---yellow mud need soak and keep humidity for a long time, in case it is dry and cracked, must leak gas, add peasant household's miscarriage, be easy to cause what is called " sick pond ", " useless pond ", make methane-generating pit lose proper function, existing national the old and new's methane-generating pit has following 1,000,000 of above problem.

Summary of the invention

The purpose of this utility model is to provide a kind of good seal performance, can not leak gas, can fast assembling-disassembling, matrix material fast assembling-disassembling methane-generating pit removable cover in light weight, easy for installation.

The purpose of this utility model is achieved in that the utility model comprises the annular pool cage that is fixed on the methane-generating pit circle, feature is that the upper end that evenly is fixed with the even number screw rod in annular pool cage intermediary projection stretches out in the screw outside the projection, the bottom, edge of circular Chi Gai is seated on the interior seat of annular pool cage, in the bottom, edge of circular Chi Gai, be processed with annular sealing-ring upper groove, on the interior seat of annular pool cage, be processed with the annular sealing-ring low groove corresponding with the sealing-ring upper groove, " O " shape sealing-ring is placed between sealing-ring upper groove and the sealing-ring low groove, and the centre of circular Chi Gai is passed and be fixed in the lower end of airway; On circular Chi Gai, be fixed with pond lid hold-down gear.

Described pond lid hold-down gear is made up of whippletree, the whippletree collar and several voussoirs, be processed with tapped screw hole in the bottom of the whippletree collar, the upper end of screw rod screws in the screw hole of the whippletree collar, make the whippletree collar be fixed on the annular pool cage, the two ends of whippletree penetrate respectively in two relative cover annular distances, and voussoir is tightly wedged between whippletree and the circular pond lid, circular Chi Gai tightly is pressed on the cage of pond, kill sealing-ring, prevent biogas from ovfl, biogas can only be discharged from airway.

Or, described pond lid hold-down gear is by pressing thick stick to form, be processed with the pressure thick stick hole that can allow the upper end of screw rod pass at the two ends of pressing thick stick, the upper end that nut screws in screw rod makes the pressure thick stick tightly push down circular Chi Gai, circular Chi Gai also just tightly is pressed on the annular pool cage, kill sealing-ring, prevent biogas from ovfl, biogas can only be discharged from airway.

Described pressure thick stick is " one " font or " T " font.

Airway lower end in the lid of circular pond is fixed with the anti-block dust gauze cover.

The place, airway both sides that covers in circular pond is symmetrically fixed with " Jiong " shape handle.

The utility model is made up of pond cage, circular Chi Gai and pond lid hold-down gear, and wherein the pond cage is to have entered with regard to pre-buried in methane-generating pit pouring process.During installation, earlier with O " the shape sealing-ring is placed in the sealing-ring low groove of pond cage; cover circular Chi Gai then; push down the interior seat of annular pool cage, upper storage reservoir lid hold-down gear is installed at last, circular Chi Gai tightly is pressed on the cage of pond; kill sealing-ring; to prevent biogas from ovfl, biogas can only be discharged from airway, when thoroughly having solved former methane-generating pit and having reloaded with the problem of yellow mud as sealing medium dehydration gas leakage.Leak testing process: insert airway with air compressor machine, inject air to 16KPAa, water or suds are smeared at the edge of circular Chi Gai overflows as no bubble, promptly installs.Circular Chi Gai is made by resin composite materials.The utility model is owing to the employing whippletree collar and screw flight combination or nut and screw flight combination, thereby installing/dismounting is all very convenient.Therefore, the utlity model has good seal performance, can not leak gas, can fast assembling-disassembling, advantage in light weight, easy for installation.
