Abstract

The utility model provides a methane-generating tank, which is mainly characterized in that the methane-generating tank comprises a tank wall body, a tank bottom, a pressure box cover, a feed port, a liquid discharge port, a gas pipe, a water pressure chamber, and vent holes, wherein the pressure box cover is a shell made of elastic material, elastic filling material is filled on the surface above the shell, a tank cover is pressed above the filling material, a bossy shell supporting surface is equipped at the inner wall of the tank body, the shell is disposed on the supporting surface, a space is arranged between the shell and the tank wall body, and vent holes are opened on the tank wall body closed to the bottom of the shell and communicated with the water pressure chamber. Compared with the prior art, the utility model has the advantages that the shell can be moved up and down, when pressure is exerted outside the shell, the shell is suspended, so as to prevent the tank wall from being broken by stress; the intoxication accident of staff can be avoided; as well as has long service life, easy maintenance and cleaning, good safety and convenience.

Description

A kind of biomass pool structure

Affiliated technical field

The utility model relates to a kind of biomass pool structure.

Background technology

Bay wall and pressure case cover that the existing methane pool structure is mainly made by rigid materials such as brick, the rectangular slab of stone and Steel Concrete, its shortcoming is, when the too high exhaust in time of pond internal pressure, or under the external force effects such as earthquake, perimeter blasting, very easily bay wall and pressure case cover are cracked, cause and leak; When maintenance and clear pond, can only be manually under the narrow and small water pressure house in the pond, very easily accident such as generation personnel poisonings owing to keeping in repair also inconvenience and poor stability, usually causes methane-generating pit to fall into disuse.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of security good, long service life, maintenance, clear pond, easy to use, biomass pool structure simple to operate.

The measure that realizes above-mentioned purpose is: the utility model comprises the bay wall body, at the bottom of the pond, press the case cover, opening for feed, leakage fluid dram, airway, water pressure house, venting hole, opening for feed and leakage fluid dram are arranged on methane-generating pit near at the bottom of the pond, leakage fluid dram communicates with water pressure house, overflow port is arranged on the water pressure house upper end, airway passes from press the case cover, water pressure house by communicate many between the pond form, described pressure case cover is the housing of being made by resilient material, surface, housing top is filled with elastic stopping composition, the stopping composition top presses Chi Gai, the housings support face of projection is set in the bay wall inner body wall, housing is placed on the bearing surface, and and the bay wall body between leave the space, communicating with water pressure house near digging venting hole on the bay wall body of housing footing.

As one of concrete enforcement of the utility model, accumulator unit can be set, accumulator unit communicates with airway by the airway arm, and accumulator unit can be arranged between housing top and the lid below, pond, is filled with elastic stopping composition around the accumulator unit.

Above-mentioned housing is an arch.

Above-mentioned airway bottom is fixed on the housing by Gap guiding bolt, nut and sealing-ring, and the airway top connects uses tracheae.

Advantage of the present utility model is: housing can move up and down, and when inside and outside the housing pressure being arranged, becomes suspension, thereby can avoid bay wall to be stressed and break, long service life, simple to operate when maintenance and clear pond, can avoid personnel's intoxication accident, security is good, and is easy to use.

Fig. 3 is that the utility model is pressed case over body case structural representation (enlarged view).

Among the figure: 1, housing, 2, stopping composition, 3, the bay wall body, 4, opening for feed, 5, nut, 6, airway, 7, bolt, 8, Chi Gai, 9, sealing-ring, 10, leakage fluid dram, 12, bearing surface, 13, pool gas, 14, liquid, 15, overflow port, 16, venting hole, 17, through hole, 18, water pressure house, 19, accumulator unit, 20, at the bottom of the pond, 22, arm, 23, standby pool.

Embodiment

Shown in Fig. 1-2, the utility model comprises at the bottom of bay wall body 3, the pond 20, presses case cover 1, opening for feed 4, leakage fluid dram 10, airway 6, water pressure house 18, overflow port 15, opening for feed 4 and leakage fluid dram 10 are arranged on methane-generating pit below near at the bottom of the pond 20, leakage fluid dram 10 communicates with water pressure house 18, overflow port 15 is arranged on water pressure house 18 upper ends, water pressure house 18 by communicate many between the pond form, through hole 17 is arranged between the pond, this example also is provided with a standby pool 23, and this standby pool 23 communicates with water pressure house 18.Pressing the case cover is the housing of being made by resilient material 1, and surface, housing 1 top is filled with elastic stopping composition 2, and stopping composition 2 tops press pond lid 8, and housing 1 is arch, and is shown in Figure 3.Bay wall body 3 inwalls be provided with the projection housings support face 12, as Figure 1-1, housing 1 is placed on the bearing surface 12, and and bay wall body 3 between leave the space.Communicating with water pressure house 18, shown in Fig. 1-2 near digging venting hole 16 on the bay wall body 3 of housing 1 footing.As Figure 1-3, airway 6 bottoms are fixed on the housing 1 by Gap guiding bolt 7, nut 5 and sealing-ring 9, and airway 6 tops connect uses tracheae.As another embodiment of the present utility model, as shown in Figure 2, promptly can between below above the housing 1 and pond lid 8, accumulator unit 19 be set, shown in Fig. 2-2, be filled with elastic stopping composition 2 around the accumulator unit 19, accumulator unit 19 communicates with airway 6 by airway arm 22, and shown in Fig. 2-3, accumulator unit 19 also can be arranged on beyond the methane-generating pit.

The utility model use principle is, owing to press case over body case 1 to move up and down, when being with pressure outside the housing 1 (as external force effects such as earthquakes), under the pressure effect of

pool gas

13,1 one-tenth suspension of housing, when the pressure of pool gas 13 reaches can be when being depressed into the footing of housing 1 the liquid in the pond 14, unnecessary gas 13 around the footing of housing 1 and venting hole 16 discharge, thereby avoid pressing the case cover to be cracked.When clear pond or maintenance, emit gas 13 earlier, extract liquid 14 in the pond out, liquid level is descended, take pond lid 8 apart, take out stopping composition 2, accumulator unit 19, housing 1 etc., get final product operation from water pressure house 18.The utility model also can be for the methane-generating pit renovation and utilization that has fallen into disuse.
