Detailed description of the invention

Fig. 1 is a kind of theory structure schematic diagram of biogas storage cabinet for sewage treatment provided by the utility model.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

As shown in Figure 1, a kind of biogas storage cabinet for sewage treatment provided by the utility model, including bottom plate 1, bottom plate 1 is slab construction, the outer tank 2 that construction opening is set up on bottom plate 1, the open setting of outer tank 2.In the case where 2 chamber of outer tank is intracorporal Side is fixedly connected with bracket 3, the down-set inner canister 4 of construction opening on bracket 3, the circumference uniform distribution four at 4 bottom opening of inner canister A clump weight 24, clump weight 24 are supported on bracket 3, and bracket 3 includes arch brace plate, the circle on the downside of the inner circle of arch brace plate Tetra- curved support plates of Zhou Junbu, four curved support plates are mounted on the tank bottom of outer tank 2.

In 2 inner wall even distribution of outer tank, three guide rails 5 being vertically arranged, guide rail 5 is the rod-shaped knot of strip that cross section is rectangle Structure ranked first support rod 6 in the outer wall of inner canister 4 uniformly distributed three, and often ranked first the quantity on support rod 6 is two, each the It is equipped in the outer circle of each directive wheel 7 by hinged one directive wheel 7 of axis connection on one support rod 6 and is equipped with annular Groove, annular groove correspondence are connected on corresponding guide rail 5.

Connection drainpipe 8 in 2 bottom of outer tank connects overflow pipe 9 at the middle part of outer tank 2, is also connected in the downside of outer tank 2 Inlet suction port 10 and air outlet adapter 11, inlet suction port 10 and air outlet adapter 11 are arranged at the lower section of inner canister 4, and inlet suction port 10 connects Tracheae 12 is tapped into, air outlet adapter 11 connects escape pipe 13, is additionally provided with the first observation window 14, the first observation window in the downside of outer tank 2 14 are correspondingly arranged at the downside of inner canister 4, the second observation window 15 are equipped at the top of inner canister 4, in the upside connection safety valve 16 of inner canister 4 With pressure gauge 17, safety valve 16 and pressure gauge 17 are the prior art.

Ladder 18 is connected in the outside of the outer tank 2, socket outer circle annular walks on stage 19 in the upside of outer tank 2, in outer toroid Shape walks on stage and is also connected with one group of second support bar 23 between 19 and the outer tank 2, and each second support bar 23 is both connected to outer toroid Shape walk on stage 19 downside.Outer guardrail 20 is installed in the circular ring shape outside above 19 of walking on stage, in 4 annular housing of outer tank 2 and inner canister Upside is equipped with inner circle annular and walks on stage 21, and inner circle annular, which is walked on stage, 21 to be socketed in inner canister 4, and inner circle annular is walked on stage the outside peaces of 21 tops Guardrail 22 in filling.

Before being passed through biogas, first injected clear water, clear water cover the opening of inner canister 4 in outer tank 2, play the water to inner canister 4 Envelope effect, after being passed through biogas from air inlet pipe 12, inner canister 4 floats under the influence of air pressure, just when inner canister 4 floats to setting position It is not floating, if at this moment air pressure continuously enlarges in tank, safety valve 16 is automatically opened, and exhaust release achievees the purpose that storage, interior Biogas tolerance air pressure reduction after using in tank 4, at this moment inner canister 4 is fallen after rise downwards under 5 guiding role of directive wheel 7 and guide rail. It finally falls on bracket 3, in addition, bottom is additionally provided with counter weight device in inner canister 4, it is therefore an objective to reduce by 4 center of gravity of inner canister, increase gas storage Amount, pressure is balanced when gas exports.
