The problem of methane-generating pit has some setbacks in the presence of charging, particularly when raw material total solids content is higher, this problem is more serious.This master
If because following two reasons cause：
1st, under normal circumstances, traditional residents methane-generating pit（Hydraulic type）Interior biogas pressure is greater than atmospheric pressure.Now,
The feed liquid water level of feed space and water pressure chamber is higher than the water level in sweathouse.It is higher in sweathouse relative to feed space and water pressure chamber
Pressure be unfavorable for charging when solid material sweathouse is entered by charging aperture.
2nd, when raw material total solids content is higher, solid matter will ordinarily accumulate in sweathouse close to the position of charging aperture,
Under no sufficient stirring state（Residents methane-generating pit usually not mixed stirring device）, this fraction solids is not easy to diffuse to
Sweathouse periphery, enter sweathouse so as to be unfavorable for new raw material.
The content of the invention
The purpose of this utility model is to overcome above mentioned problem existing for prior art, there is provided a kind of new residents biogas
Pond.Using the utility model be advantageous to charging when solid material sweathouse is entered by charging aperture, when raw material total solids content compared with
Gao Shi, this fraction solids are easy to diffuse to sweathouse periphery.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of new residents methane-generating pit, including feed space, sweathouse and water pressure chamber, it is characterised in that：Also include charging
System, feed system include feed liquid circulation pipe, circulating pump, buffer pool, separator tube and pressure vacuum gauge, and circulating pump is arranged on hydraulic pressure
In, circulating pump is connected to buffer pool by feed liquid circulation pipe, and circulation pipe valve is provided with feed liquid circulation pipe, and buffer pool passes through
Separator tube is connected with feed space, and buffering tube valve is provided with separator tube, and pressure vacuum gauge is arranged on the natural pond being connected with sweathouse
On tracheae.
Two circulation pipe valves are provided with the feed liquid circulation pipe, circulating pump is connected between two circulation pipe valves
On feed liquid circulation pipe.
The dischargeable capacity of the buffer pool is more than level of significance area × 10cm of water pressure chamber.
Biogas tube valve is provided with the biogas pipe, pressure vacuum gauge is arranged between biogas tube valve and sweathouse
On biogas pipe.
The gentle washing pipe valve of the circulation pipe valve is gate valve, and biogas tube valve is ball valve.
Using the utility model has the advantage of：
1st, in methane-generating pit it is negative pressure during charging, raw material can be easy to enter by feed pipe after using the utility model
Inside methane-generating pit sweathouse.
2nd, after using the utility model, made by the way that the biogas slurry backflow in buffer pool can also be played into a certain degree of stirring
With uniform the solid material for feeding bottom of the tube is stirred into sweathouse bottom.
Brief description of the drawings
Fig. 1 is the utility model structure diagram
In figure mark for：1st, feed space, 2, sweathouse, 3, water pressure chamber, 4, biogas pipe, 5, biogas tube valve, 6, feed liquid follows
Endless tube, 7, circulating pump, 8, buffer pool, 9, circulation pipe valve, 10, separator tube, 11, buffering tube valve, 12, pressure vacuum gauge.
Embodiment
Embodiment 1
A kind of new residents methane-generating pit, including feed space 1, sweathouse 2 and water pressure chamber 3, in addition to feed system, charging
System includes feed liquid circulation pipe 6, circulating pump 7, buffer pool 8, separator tube 10 and pressure vacuum gauge 12, and circulating pump 7 is arranged on hydraulic pressure
Between in 3, circulating pump 7 is connected to buffer pool 8 by feed liquid circulation pipe 6, and circulation pipe valve 9 is provided with feed liquid circulation pipe 6, buffering
Pond 8 is connected by separator tube 10 with feed space 1, and buffering tube valve 11 is provided with separator tube 10, and pressure vacuum gauge 12 is arranged on
On the biogas pipe 4 being connected with sweathouse 2.
In the present embodiment, two circulation pipe valves 9 are provided with the feed liquid circulation pipe 6, circulating pump 7 is connected to two and followed
On feed liquid circulation pipe 6 between endless tube valve.
In the present embodiment, the dischargeable capacity of the buffer pool 8 is more than level of significance area × 10cm of water pressure chamber 3.
In the present embodiment, biogas tube valve 5 is provided with the biogas pipe 4, pressure vacuum gauge 12 is arranged on biogas pipe valve
On biogas pipe 5 between door 5 and sweathouse 2.
In the present embodiment, the circulation pipe valve 9 washing pipe valve 11 that eases up is gate valve, and biogas tube valve 5 is ball valve.
Embodiment 2
The present embodiment combination accompanying drawing is described further to the utility model.
As shown in figure 1, a kind of new residents methane-generating pit, except the agent structure and facility of methane-generating pit：Feed space 1, fermentation
Between 2, water pressure chamber 3, outside biogas pipe 4 and biogas tube valve 5, the feed system of setting includes feed liquid circulation pipe 6, circulating pump 7, buffering
Pond 8, circulation pipe valve 9, separator tube 10, buffering tube valve 11 and pressure vacuum gauge 12.
Design buffer pool dischargeable capacity V is greater than water pressure chamber level of significance area × 10cm；Circulation pipe valve 9 and separator tube
Valve 11 selects gate valve, and biogas tube valve 5 selects ball valve；The range of pressure vacuum gauge 12 is peak suction -0.1MPa；Remaining sets
Apply, device specification, parameter design according to biogas pool volume.
Feed operation preferably selects to carry out after domestic gas is occupied, and now air pressure is relatively low in methane-generating pit or air pressure is zero.First will
The washing pipe valve 11 that eases up of biogas tube valve 5 is closed, and opens valve of the circulation pipe valve 9 close to buffer pool side, is then opened and is followed
