Abstract

The invention discloses a kind of methane tank residue-extracting device, relate to agricultural technology field；Including a solid-liquid separator, one end of the liquid suction pipe of solid-liquid separator connects suction pump and stretches into the bottom of methane-generating pit, one end of the liquid back pipe of solid-liquid separator puts in the gas dome of methane-generating pit, and one end of the return pipe of solid-liquid separator connects the water pressure chamber of described methane-generating pit；The present invention can solve to clear up the problem that methane-generating pit time length, manually consuming pond personnel big, clear are dangerous and pollute environment in prior art.

Description

Methane tank residue-extracting device

Technical field

The present invention relates to agricultural technology field, a kind of device mechanically extracted out in pond by the waste residue in methane-generating pit.

Background technology

Methane-generating pit, mainly it is made up of feed space, water pressure chamber, sweathouse, removable cover, appendix etc., wherein feed space, water pressure chamber are connected with sweathouse by pipeline, appendix is arranged on removable cover, its end communicates with the gas equipment of user family, lower end connects with the gas dome above fermentation vat, after methane-generating pit uses a period of time, biogas residue in pond can be deposited on the bottom of sweathouse in large quantities, these biogas residue of time length can gradually take the big quantity space of sweathouse, has a strong impact on the gas producing efficiency of methane-generating pit；When this situation occurs, the methane-generating pit in current most of area uses artificial clear pond, common practice is to be disabled by methane-generating pit, open removable cover, first the liquid in pond is completely drawn out, sending someone down, under pond, solid biogas residue little by little to be cleared from the bottom of pond, the most again discharging water and putting into fermentation raw material enables methane-generating pit again；Clear up a methane-generating pit ordinary circumstance and need the used time two days, and also there is the substantial amounts of manpower of consuming, clear pond personal security without the problem ensured and pollute environment.

Summary of the invention

It is an object of the invention to provide a kind of device clearing up methane-generating pit biogas residue, it can solve the problem that clear pond time length in prior art, manually consuming pond personnel big, clear are dangerous and pollute environment.

In order to solve the problems referred to above, the technical solution used in the present invention is: this methane tank residue-extracting device, including a solid-liquid separator, one end of the liquid suction pipe of described solid-liquid separator connects suction pump and stretches into the bottom of methane-generating pit, one end of the liquid back pipe of described solid-liquid separator puts in the gas dome of described methane-generating pit, and one end of the return pipe of described solid-liquid separator connects the water pressure chamber of described methane-generating pit.

Owing to have employed technique scheme, the present invention compared with prior art has the advantages that

1, use the cleaning biogas generating pit apparatus of the present invention, only need can be cleaned out by methane-generating pit for three hours；

2, it is not required to all to drain liquid in pond, it is to avoid during clear pond, liquid in pond is all discharged the problem causing environmental pollution outside pond in the past；

3, lower pond of sending someone it is not required to, it is to avoid the safety problem that when residual gas is not completely exhausted out in pond, under personnel, pond is likely to result in；

4, the biogas residue cleaned out is transported in can being directly loadable into packaging bag, will not be to environment；

5, the clear pond time shortened to three hours from original two days, does not interferes with peasant family and is just commonly using gas.

Accompanying drawing explanation

Fig. 1 is methane tank residue-extracting device (containing methane-generating pit) schematic diagram of the present invention.

Detailed description of the invention

The present invention is further described by embodiment below in conjunction with the accompanying drawings:

This methane tank residue-extracting device, including a solid-liquid separator 9, one end of the liquid suction pipe 1 of solid-liquid separator 9 connects suction pump 10 and puts into the bottom of methane-generating pit 5, one end of the liquid back pipe 2 of solid-liquid separator 9 puts in the gas dome 8 of methane-generating pit 5, and one end of the return pipe 3 of solid-liquid separator 9 connects the water pressure chamber 7 of methane-generating pit 5.

When slag taken out by methane-generating pit 5, first start the motor 11 of solid-liquid separator 9, restart the motor of suction pump 10, now, slag inclusion liquid in methane-generating pit 5 enters the input of solid-liquid separator 9 through liquid suction pipe 1, and by the pressurizing unit extrusion moisture content in solid-liquid separator 9, the moisture content of extrusion flows back to methane-generating pit water pressure chamber 7 from return pipe 3, the biogas residue extruding moisture content then discharges the outside of solid-liquid separator 9 by slag notch 4, if when liquid suction pipe 1 is pumped into the treating capacity that the slag inclusion liquid of solid-liquid separator 9 input exceedes solid-liquid separator 9, unnecessary slag inclusion liquid then flows back to methane-generating pit through liquid back pipe 2；So through the most repeatedly, the dregginess of the liquid in methane-generating pit 5 gradually decreases, and when liquid dregginess reaches requirement in pond, stops pumping pump 10 and solid-liquid separator 9 works, withdrawn from by methane tank residue-extracting device, methane tank residue-extracting end-of-job in gas pond, pond；Putting into fermentation raw material and supplementary water from the charging aperture 6 of methane-generating pit 5, build the various lids of methane-generating pit 5, methane-generating pit can start to reuse.

Claims

1. a methane tank residue-extracting device, it is characterized in that: include a solid-liquid separator (9), one end of the liquid suction pipe (1) of described solid-liquid separator (9) connects suction pump (10) and stretches into the bottom of methane-generating pit (5), one end of the liquid back pipe (2) of described solid-liquid separator (9) puts in the gas dome (8) of described methane-generating pit (5), and one end of the return pipe (3) of described solid-liquid separator (9) connects the water pressure chamber (7) of described methane-generating pit (5).
