Description
Technical field
The utility model relates to a kind of methane-generating pit, especially relates to a kind of gas storage hydraulic type automatic sludge discharge methane-generating pit.
Background technology
At present, the methane-generating pit of promoting in China rural area generally adopts the structure of round shape hydraulic pressure firedamp type, M3 round tube type hydraulic biomass pool with national standard is an example, the constructional feature of its pond type is 1, main pond belongs to circular, big with respect to its capacity of other shapes (as oval, square body), wall is stressed evenly, and the pond body is firm relatively, cloth is even after the charging, and it is more abundant to ferment; 2, adopt hydraulic type, its top, main pond gas dome complete closed, discharge room (being commonly called as secondary pond) is discharging place, is again water pressure house.Along with the continuous generation of biogas, liquid level increases between main pond.When using gas, biogas reduces, and the feed liquid of water pressure house is returned in the pond again.Like this, the string back and forth of part feed liquid is moving, causes the variation repeatedly of hydraulic pressure, reaches the purpose of storing and discharging biogas.
The major advantage of above-mentioned methane-generating pit is: 1, can inflate the supporting capacity of utilizing soil, body stressed property in pond is good; 2, be suitable for loading multiple fermentation raw material (for example swine excrement, crop tangerine bar etc.); 3, be convenient to frequent charging, pig house, feces of toilet can both be swept into pond at any time; 4, all contact with soil around the body of pond, insulation has certain effect to the pond body.But there is following shortcoming: 1, change repeatedly, the light fixture of pond body intensity and use biogas, the stable and raising of kitchen range efficiency of combustion are all had adverse influence owing to air pressure; 2, owing to there is not whipping appts, scum silica frost crusts easily in the pond, is difficult to fragmentation again, so the utilization ratio of fermentation raw material is not high, and pond appearance factor of created gase is on the low side, and (only be 0.15m every day
3/ m
3About); 3, owing to having only a fermentation vat, more frequent when charging, when inlet amount is big, some raw materials are just overflowed without fermentation, can not fully ferment.
Summary of the invention
The purpose of this utility model is the shortcoming at existing round tube type hydraulic type biomass pool existence, a kind of construction that is suitable for big-and-middle-sized fermentation system fen is provided, the construction time is short, it is more abundant to ferment, factor of created gase is higher, and air feed is more uniform and stable, and it is convenient that wooden dipper is ladled out slag liquid, natural pond material utilization ratio is higher, can effectively solve the gas storage hydraulic type automatic sludge discharge methane-generating pit of scum silica frost crust and residue deposition problems.
The utility model is provided with Primary Fermentation pond, side fermentation pond, outlet pipe, slag off apparatus, motor, be communicated with between Primary Fermentation pond and the side fermentation pond, Primary Fermentation pond one side is provided with opening for feed and handle hole, side fermentation pond one side is established slag-drip opening, overflow port is established at one side slag-drip opening top in the side fermentation pond, outlet pipe is located at respectively in Primary Fermentation pond and the side fermentation pond, and outlet pipe extends to handle hole from Primary Fermentation pond and side fermentation Chi Chiding respectively at the bottom of the pond; Slag off apparatus is located at Primary Fermentation pond and bottom, side fermentation pond, and slag off apparatus connects motor.
Can establish pod apertures on the medial axis at the bottom of Primary Fermentation pond and the pond, side fermentation pond, described slag off apparatus can be installed along medial axis direction at the bottom of Primary Fermentation pond and the pond, side fermentation pond, and described slag off apparatus can adopt the roller slag off apparatus, and one of slag off apparatus reaches handle hole and the motor of ining succession.When motor rotated, the screw-blade on the slag off apparatus promoted the material slag and advances, and the material slag in Primary Fermentation pond can smooth and easyly move to the side fermentation pond.Described Primary Fermentation pond and side fermentation Chi Chiding can adopt the metal pool top, and the iron sheet that the metal pool top can adopt anti-corrosion spray to handle forms through the overmolding manufacturing.Described Primary Fermentation pond is circular Primary Fermentation pond.
Because the gas dome on major and minor fermentation vat of the present utility model top is not established direct air outlet, and outlet pipe is extended to handle hole from Primary Fermentation pond and side fermentation Chi Chiding at the bottom of the pond, and establish valve and airway at handle hole, simultaneously establishing pod apertures on the medial axis at the bottom of Primary Fermentation pond and the pond, side fermentation pond, described slag off apparatus can be installed along medial axis direction at the bottom of Primary Fermentation pond and the pond, side fermentation pond, described slag off apparatus adopts the roller slag off apparatus, and one of slag off apparatus reaches handle hole and the motor of ining succession.When motor rotated, the screw-blade on the slag off apparatus promoted the material slag and advances, and the material slag in Primary Fermentation pond can smooth and easyly move to the side fermentation pond.This shows, compare, the utlity model has following outstanding advantage with existing methane-generating pit:
1) owing to adopt Primary Fermentation pond and side fermentation pond, therefore increases the fen capacity, be fit to build big-and-middle-sized methane-generating pit.
2) because Chi Ding adopts the forming metal material, so construction volume reduces in a large number, shortens and builds the pond time.
3) because the roller slag off apparatus is installed, therefore can regularly stir and move slag at the bottom of Primary Fermentation pond and pond, side fermentation pond, effectively solve scum silica frost crust and residue deposition problems the material slag, the material slag is fully fermented, the factor of created gase height, air feed is uniform and stable, it is convenient that wooden dipper is ladled out slag liquid, natural pond material utilization ratio height.
