Abstract

The utility model relates to a multi-function automatically slag discharging methane-generating pit, which mainly solves the disadvantages of inconvenient slag discharge, easy methane liquid wasting and incrustation easily generated during the time of fermentation of the prior art. The bottom of the methane-generating pit during the time of fermentation is connected with a slag discharging pipe; the upper end of the slag discharging pipe is connected with a slag discharging pit; the middle part of the slag discharging pipe is connected with a reflux pipe; the upper end of the reflux pipe is positioned on the upper part of the fermenting room; the middle part of the fermenting room is connected with a liquid outlet pipe; the upper end of the flow outlet pipe is connected with a water pressure pit and is provided with a screw cap with a one-way valve. The utility model has the advantage of convenient slag discharging; the methane liquid and slag materials can be respectively discharged; liquid materials which flow out through the reflux pipe can break the generation of the incrustation.

Description

Multi-function automatically slag discharging methane-generating pits

But the utility model relates to a kind of device of process gas fuel, a kind of multi-functional methane-generating pit of slagging tap automatically of more specifically saying so.

In the prior art, no matter be to use cast-in-place concrete marsh-gas pond, place also to be to use prefabricated methane-generating pits such as plastics, cast iron and concrete, all forming by feed-pipe, sweathouse, sweathouse removable cover, discharge nozzle and water pressure house etc.Its shortcoming mainly contains following two: the one, a discharge nozzle only is housed on the sweathouse, and this discharge nozzle generally is middle part or the bottom that is installed in sweathouse.The methane-generating pit that discharge nozzle the is installed in sweathouse middle part inconvenience of slagging tap needs to adopt the method for big discharging, big charging, and uses the bottom between secondary fermentation to be prone to sediment, and the sweathouse volume is descended, and gas production rate reduces; And discharge nozzle when being installed in the methane-generating pit of sweathouse bottom and slagging tap slag liquid mix, make can pasture natural pond liquid cause waste, and when in the slag charge silt being arranged, discharge nozzle stops up especially easily, and slag liquid is flowed out from opening for feed on the contrary.The 2nd, the fluid surface in the sweathouse crusts especially easily, influences the generation of biogas.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of convenience of slagging tap, slag liquid can to flow out respectively, and can abolish the incrustive multi-functional methane-generating pit of slagging tap automatically of liquid level automatically.

For finishing above-mentioned purpose, technical solution provided by the utility model is: a kind of multi-functional methane-generating pit of slagging tap automatically, comprise opening for feed 1 and coupled feed-pipe 2, sweathouse 3 and removable cover 4 thereof, its special character is, be connected with a residue outlet 11 in the bottom of described sweathouse 3, the upper end of this residue outlet 11 with go out slag bath 9 and link to each other, the residue outlet middle part connects a return line 12, the upper end of this return line is positioned at the top of sweathouse 3, middle part at described sweathouse 3 connects a drain pipe 10, and the upper end of this drain pipe 10 links to each other with hydraulic pressure pond 6 and a screw-cap 8 that is provided with check valve is installed.

Go out the bottom that slag bath 9 can be positioned at hydraulic pressure pond 6 described in the above-mentioned technical solution, can save material and reduce the volume of methane-generating pit like this.

The screw-cap 8 that is provided with check valve in the above-mentioned technical solution can also be installed a stopping valve 7 afterwards.

Accompanying drawing has been described a preferred embodiment of the present utility model.

Fig. 1 is the sectional structure chart of this embodiment;

Fig. 2 is the vertical view of Fig. 1.

Referring to Fig. 1, Fig. 2 knows, this multi-functional methane-generating pit of slagging tap automatically has a sweathouse 3, connect a feed-pipe 2 and opening for feed 1 on this sweathouse 3, a removable cover 4 is stamped on sweathouse 3 tops, airway 5 is located on this removable cover 4, the lower end of residue outlet 11 links to each other with the bottom of sweathouse 3, the upper end with go out slag bath 9 and link to each other, the lower end of return line 12 links to each other with the middle part of residue outlet 11, and the upper end is positioned at the top of sweathouse 3, and the lower end of drain pipe 10 links to each other with the middle part of sweathouse 3, the upper end links to each other with hydraulic pressure pond 6, a screw-cap 8 that is provided with check valve is equipped with in its upper end, and a shut off valve 7 also is housed thereafter, describedly goes out the bottom that slag bath 9 is positioned at hydraulic pressure pond 6.

Drop into the raw material that can produce biogas from opening for feed 1 during use, these raw materials ferment in sweathouse 3 and promptly produce biogas after for some time, biogas is sent to methane cooker by airway 5, sending biogas, under the situation that sweathouse 3 internal pressures reduce, part liquid material will in hydraulic pressure pond 6 and go out under the effect of liquid pressure in the slag bath 9 and flow in the sweathouses 3 through return line 12, these liquid material drip liquid level to sweathouse from the mouth of pipe of return line 12, this has also just destroyed issuable crust in the sweathouse, has the effect of broken shell.Natural pond liquid can flow into hydraulic pressure pond 6 by drain pipe 10, and slag charge then can enter out slag bath 9 by residue outlet 11, and is more convenient for deslagging, stopping valve 7 can be closed, and relies on the gaseous tension in the sweathouse 3 that slag charge is discharged.If be provided with when on the screw-cap 8 of check valve shut off valve not being installed, be residue-discharge convenience, also the screw-cap 8 that is provided with check valve can be unloaded, load onto the screw-cap of a sealing.

Can find out that in conjunction with above-described embodiment the utility model has following advantage compared to existing technology:

1, drain pipe and residue outlet are installed in respectively on the sweathouse, and natural pond liquid and slag charge are discharged respectively, be unlikely like this make can pasture natural pond liquid cause waste;

2, slag tap more conveniently, need not adopt the slag tapping method of big discharging, big charging;

3, can make part liquid material drip liquid level in the sweathouse from the return duct mouth of pipe by return duct, thereby destroy the generation of liquid level crust in the sweathouse, guarantee the normal gas producing of methane-generating pit.
