Abstract

The utility model discloses a novel automatic slag drainage biogas pool, which belongs to the technology field of a biogas fermentation device and particularly relates to a biogas fermentation pool without manpower and with the biogas being discharged by a machine. The shape of the transverse section of the pool body is round. The pool bottom is an inclined conchoid shell with an upward opening; and the lowest place of the conchoid shell pool bottom is provided with a straight material outlet pipe. The upper end of the material outlet pipe passes through the pool lid or the upper part of the pool body and is exposed outside the pool body. The middle part of the opposite pool body of the material outlet pipe is provided with an upward inclined material inlet pipe. The top end port of the material inlet pipe is higher than the top end port of the material outlet pipe. A gas-transporting pipe is provided above the pool lid. The pool body, the pool lid and the pool bottom are fixedly connected into a whole. The utility model has advantages of: 1. reasonable structure, simple construction, convenient management, low price, being solid and durable, and long service life; 2. fully automatic feeding and discharge of the materials; 3. sufficient gas supply, strong firepower, and small occupying area; 4. being suitable for matching with various ground buildings; 5. being especially suitable for using in countryside.

Description

The new type auto formula methane-generating pit of slagging tap

Technical field

The utility model belongs to the biogas fermentation device technical field, is specifically related to a kind of family with need not marsh gas fermentation pool artificial, mechanical discharging.

Background technology

In the rural area, the application of biogas is popularized just day by day, and at present, it is hydraulic type biomass pool the most widely that China applies in the rural area.This pond type still has following disadvantage: one, the labor capacity of methane-generating pit charging and discharging is bigger, the management inconvenience in the use, and the generation of personnel's poisoning is often arranged in the process of reloading; Two, all to open the pond discharging and reload every year, the use of biogas is interrupted, but also can shorten the work-ing life of methane-generating pit; Three, pond shape complex structure, constructional difficulties, technical quality are difficult to grasp, and cost is higher, thereby has seriously restricted the popularization on a large scale of biogas.

The utility model content

At the above-mentioned deficiency of prior art, the technical problems to be solved in the utility model provides a kind of new type auto formula methane-generating pit of slagging tap, and its construction is simple, and convenient management is with low cost, but self-emptying, thereby have application value widely.

The technical solution of the utility model is: the new type auto formula methane-generating pit of slagging tap, contain fermentation vat pond body, Chi Gai, at the bottom of the pond, pneumatic tube, feed-pipe and discharge nozzle, it is characterized in that: described pond body shape of cross section is for circular, it at the bottom of the pond conchoidal housing that an opening of tiltedly putting makes progress, lowest part is provided with the discharge nozzle of straight pipe type at the bottom of the conchoidal pond, Chi Gai or body top, pond are passed in the upper end of discharge nozzle, expose outside the body of pond, be provided with the feed-pipe that is tilted at the offside pond of discharge nozzle body middle part, the upper port of feed-pipe is higher than the upper port of discharge nozzle, and pneumatic tube is arranged on the lid of pond.Be connected to one at the bottom of described pond body, Chi Gai and the pond.

The utlity model has following advantage:

1, rational in infrastructure, construction is simple, and convenient management is cheap, sturdy and durable, long service life;

2, do not use artificial or mechanical discharging, fully automatic feed/discharge;

3, the defective material after the fermentation can in time be discharged outside the pond, is convenient to further enter virgin material, and tolerance is sufficient, firepower is big, it is few to take ground;

4, can be supporting with multiple surface structures, there is the place in domestic refuse source all can supportingly to use as public lavatory, city, residential building, food market, sewage draining exit etc.;

5, the utility model is particularly suitable for villages and towns in rural areas family and plant etc. has the place in domestic refuse source to use.

Description of drawings

Accompanying drawing 1 is the utility model one example structure synoptic diagram.

Accompanying drawing acceptance of the bid keep the score state as follows: the 1-opening for feed; The 2-feed-pipe; 3-pond body; The 4-local horizon; 5-Chi Gai; At the bottom of the 6-pond; The 7-pneumatic tube; 8-feed liquid position; The 9-discharge port; The 10-guide groove; The 11-discharge nozzle; 12-dreg chamber.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.Embodiment as shown in Figure 1 is arranged on underground, and it also can be arranged on the ground.The pond body 3 of methane-generating pit is a round shape, and this round shape pond body has stressed even, and the pond body is firm, anti-interior pressure, the strong characteristics of outer bloated effect; And the pond holds and raw material is rationally utilized, no dead angle, can stir, pond appearance gas producing efficiency height.The pond lid 5 of methane-generating pit as shown is dome (it also can be arranged to other shape, as long as guarantee load-bearing), and this structure has effects such as anti-deadweight, anti-negative pressure and anti-inner outwards expansible positive pressure.6 as conchoidal at the bottom of the pond of methane-generating pit, and it has anti-ground water pressure, increases the thrust surface of whole pressurized, not by pressure break, stops advantages such as methane-generating pit sinking at the bottom of the assurance pond.6 are inclined at the bottom of the pond at the bottom of the conchoidal pond, and its feeding side is higher than exit side, have the very big gradient, when the pond of methane-generating pit body 3 diameters are 3.5-3.6m, at the bottom of the conchoidal pond between the 6 high-end and low sides drop be that 75cm to 85cm is proper.The size of the drop at the bottom of the conchoidal pond between 6 the high-end and low side is that if the diameter of methane-generating pit pond body 3 is less, the drop at the bottom of the conchoidal pond between 6 the high-end and low side is also less along with the diameter of methane-generating pit pond body 3 increases and increases.This structure can make the defective material after the fermentation slide into discharge nozzle easily, when gas production vigorous period or stop to use the gas stage, owing to rising along with the rising of methane-generating pit internal gas pressure in the feed liquid position in the discharge nozzle, after liquid level rises to certain altitude, feed liquid promptly can flow out automatically from discharge port, enters in the dreg chamber continuously or directly enters vegetable plot, field.At upper port 9 places of discharge port, drive a guide groove 10 (upper port of discharge port also can flush or a little less than ground) under the local horizon 4 with ground, it can be with automatic effusive slag liquid row in dreg chamber 12.If guide groove 10 and dreg chamber 12 suitable for reading needs add a cover it, to guarantee people and animals' safety exposed outside the time.The another side of the pond body 3 relative with discharge nozzle 11, feed-pipe 2 is set, the upper port of feed-pipe 2 should be than discharge nozzle upper port height, could guarantee can not allow the interior feed liquid of methane-generating pit be forced out from feed-pipe 2, feed-pipe 2 suitable for reading is provided with an opening for feed 1 in the diagram, opening for feed 1 herein can not wanted at other embodiment yet, and feed-pipe 2 directly is connected with the outfall sewer of raw material sources such as side bilge or toilet.If suitable for reading when exposed, also should add a cover.When aerogenesis is not enough, can consider to feed in raw material.Methane-generating pit of the present utility model is all-in-one-piece, its structural integrity, and construction is a kind of novel domestic methane tank of applying in the rural area of being particularly suitable for easily.
