Description
Technical field
The utility model relates to a kind of methane-generating pit, particularly a kind of pneumatic slagging-off methane-generating pit.
Background technology
Traditional methane-generating pit all will carry out one to twice big discharging every year, need fasten the safety belt when the people goes into the pond discharging, also will stay the special messenger safety prevention measure such as to guard on discharge port.Though it is good that the masses are generally reflected methane-generating pit, but it is many to go into pond discharging potential safety hazard, the annual situation that loss of life and personal injury all takes place during the biogas discharging, thereby greatly reduce popularizing and promoting of methane-generating pit, reduced the work-ing life of methane-generating pit greatly, and the gas production rate of traditional methane-generating pit is because insufficient utilization of raw material causes gas production rate not high.
Summary of the invention
The purpose of this utility model is exactly a kind of pneumatic slagging-off methane-generating pit of inventing for the shortcoming that overcomes prior art.
The purpose of this utility model can realize by following technical proposal: a kind of pneumatic slagging-off methane-generating pit of the present utility model, comprise opening for feed, airway, dreg-drawing pipe, proving room, discharge port, at the bottom of the pond of proving room for from the opening for feed to the discharge port, to reduce gradually, form a slope, and the angle of slope and horizontal plane is the 20-25 degree, be provided with backflow pool in the discharge port upper end, and backflow pool is connected by second return line with proving room, this second return line is provided with the second movable non-return valve at an end of proving room, between discharge port and backflow pool, be provided with first return line, and this first return line is provided with the first movable non-return valve at backflow pool one end, movable flashboard is installed between proving room and discharge port, on the movable flashboard pull bar is arranged.
One end of dreg-drawing pipe is positioned at backflow pool, and the other end is positioned at proving room.
The upper end of movable flashboard has row's overflow weir, and overflow weir is from the upper edge of movable flashboard down in 10-15 centimetre the scope, and the shape of overflow weir can be circle, square and other shapes.
The angle of slope and horizontal plane can be 23 degree.
The utility model is to have solved the difficult problem of methane-generating pit slagging-off, after starting, can effectively alleviate or prolong the slagging-off cycle, even can not advance in the pond and just the natural pond slag can be removed, thereby eliminated the potential safety hazard that biogas causes because of mismanagement, the safety performance of methane-generating pit gets a promotion.
Pneumatic slag removal of the present utility model is: the utility model has strengthened the gradient at the bottom of the pond, between discharge port and proving room, be provided with movable flashboard, prevent that natural pond slag and bacterial classification run off, second return line is set between backflow pool and proving room, second return line is provided with the second movable non-return valve at an end of proving room, when smoke movable flashboard by pull bar, when the methane-generating pit air pressure inside changes, discharge port middle level liquid arrives backflow pool by first return line flow, natural pond liquid in the backflow pool flows into proving room by second return line that is arranged between backflow pool and the proving room again, make and form automatic convection circulation between discharge port and the proving room, thereby improved natural pond liquid, natural pond slag interaction, reach broken shell gas production rate raising in the pond, the natural pond slag reaches the effect that the pond is not gone in slagging-off because of the interactive come-up automatically of convection current.The design of dreg-drawing pipe is adopted oblique cutting to go into mode and is inserted proving room, is convenient to the dense fertile slag of height is extracted out from the proving room bottom.
