Brief description the utility model discloses a work flow:
s01, collecting kitchen garbage and excrement of users respectively by a kitchen garbage collecting pipe 12 and a toilet excrement collecting pipe 13, then uniformly discharging the collected kitchen garbage and excrement into a sediment deposition chamber 112 of a building pool body 11, wherein large garbage is intercepted by a net bag 114 and retained in the net bag 114, after being cleaned uniformly by workers in the future, the rest part falls into the sediment deposition chamber 112 through the net bag 114, small garbage with higher density in the rest part is sunk into the bottom of the sediment deposition chamber 112, after being uniformly salvaged by workers in the future, kitchen and toilet waste pulp in the rest part flows into a mixed waste pulp containing chamber 113 through meshes on a grid plate 111, and when the mixed waste pulp in the mixed waste pulp containing chamber 113 is stored to a certain liquid level, the mixed waste pulp is automatically discharged through a mixed waste pulp output pipe 14.
In this step, the opening and closing control mechanism of the pipe orifice of the mixed waste slurry output pipe 14 controls the opening or closing of the pipe orifice of the tank body 11, so as to automatically discharge the mixed waste slurry in the inner cavity of the tank body 11. The working principle of the pipe orifice opening and closing control mechanism is as follows:
a. in an initial state, the amount of the mixed waste slurry in the inner cavity of the tank body 11 is small, and along with the accumulation of the mixed waste slurry in the mixed waste slurry accommodating cavity 113, the liquid level in the inner cavity of the tank body 11 is continuously raised until the liquid level overflows the floating ball a153, so that the long arm 1521 of the lever 152 tends to rotate upwards, but the lower edge of the limiting plate 1571 abuts against the pulley 1576, so that the upward rotation of the long arm 1521 of the lever 152 is limited.
b. Along with the further hoarding of mixed waste pulp in the mixed waste pulp accommodation cavity 113, the liquid level in the inner cavity of the tank body 11 is further lifted, so that the floating ball B1578 is synchronously lifted along with the liquid level, when the liquid level in the inner cavity of the tank body 11 reaches the preset liquid level, the floating ball B1578 tensions the rope B1577 under the action of the buoyancy generated by the floating ball B1578, the tension of the rope B1577 overcomes the elastic force of the spring 1575, the pulley seat 1574 is pulled to move towards the direction far away from the lever 152, and the pulley 1576 is separated from the contact with the lower edge of the limit plate 1571.
c. When the pulley 1576 is disengaged from the lower edge of the limit plate 1571, the long arm 1521 of the lever 152 is immediately rotated upward under the buoyancy provided by the floating ball a153, so that the rope a157 is tightened, the cover plate 154 is rotated to a horizontal state by the pulling of the rope a157, so that the nozzle of the mixed waste slurry outlet pipe 14 at one end of the mixed waste slurry containing cavity 113 is opened, and the mixed waste slurry in the mixed waste slurry containing cavity 113 is immediately discharged through the mixed waste slurry outlet pipe 14.
d. Along with the discharge of the waste slurry in the mixed waste slurry containing cavity 113, the liquid level in the inner cavity of the building pool body 11 continuously drops, the floating ball B1578 loosens the rope B1577 along with the drop of the liquid level, so that the pulley seat 1574 loses the pulling force of the rope B1577 and gradually moves towards the direction close to the lever 152 under the elastic force of the spring 1575, meanwhile, the floating ball a153 also drives the long arm 1521 of the lever 152 to rotate downwards along with the drop of the liquid level, so that the rope a157 is loosened, the cover plate 154 loses the pulling force of the rope a157, and then rotates downwards under the action of the self gravity to cover the nozzle of the mixed waste slurry output pipe 14, so that the nozzle of one end of the mixed waste slurry output pipe 14, which is located in the mixed waste slurry containing cavity 113, is closed, and finally, the pulley 1576 moves to the state of contacting with the lower edge of the limiting plate.
e. The above-mentioned a-d steps are repeated, so that the mixed waste slurry in the mixed waste slurry containing cavity 113 is automatically discharged.
S02, the mixed waste slurry is discharged from the mixed waste slurry output pipe 14, sucked into the mixed waste slurry input pipe 23 through the pipeline under the negative pressure action of the inner cavity of the pool body 21, and then sucked into the inner cavity of the pool body 21, and automatically discharged through the mixed waste slurry extraction pipe 241 after the mixed waste slurry in the inner cavity of the pool body 21 is accumulated to a certain liquid level height.
In this step, the vacuum pressure in the chamber of the tank 21 is controlled to be 0.15 to 1.5kg/cm by the vacuum pressure adjusting mechanism A2Further assisted by negative pressureThe mixed waste slurry discharged through the mixed waste slurry outlet pipe 14 rapidly enters the inner chamber of the tank body 21. The working process of the negative pressure regulating mechanism A is as follows: the air pressure detection unit A221 detects the air pressure at the upper end of the inner cavity of the pool body 21 in real time; when the liquid level in the inner cavity of the community body 21 rises to cause the volume of the inner cavity of the community body 21 to be reduced, so that the pressure in the inner cavity of the community body 21 is increased, and the air pressure detection unit A221 detects that the pressure in the inner cavity of the community body 21 is increased to exceed the preset upper limit value, the vacuum pump A222 is started immediately, part of air in the inner cavity of the community body 21 is pumped out and stored in the air storage tank A223, so that the pressure in the inner cavity of the community body 21 is reduced to 0.15-1.5 kg/cm2The content of the compound is less than the content of the compound; when the liquid level in the inner cavity of the social pool body 21 is reduced to reduce the pressure in the inner cavity of the social pool body 21 to be lower than the preset lower limit value, the electric control valve on the pipeline connected to the exhaust port of the air storage tank A223 is opened, the gas stored in the air storage tank A223 is conveyed into the inner cavity of the social pool body 21 through the pipeline under the action of negative pressure in the inner cavity of the social pool body 21, and the pressure in the inner cavity of the social pool body 21 is increased to 0.15-1.5 kg/cm2Within.
In this step, the tank body 21 controls the mixed waste slurry in the inner cavity thereof to be automatically discharged through the mixed waste slurry discharge pipe 241 by the mixed waste slurry discharge mechanism. The working process of the mixed waste slurry pumping mechanism is as follows: as more and more mixed waste slurry is accumulated in the inner cavity of the community body 21, the liquid level of the mixed waste slurry is continuously raised, when the high liquid level calibrated by the high liquid level detection unit 244 is reached, the sewage pump 242 is started, the waste slurry in the inner cavity of the community body 21 is pumped out through the mixed waste slurry pumping pipe 241, the liquid level in the inner cavity of the community body 21 is immediately lowered, and when the low liquid level calibrated by the low liquid level detection unit 244 is reached, the sewage pump 242 is closed.
S03, discharging the mixed waste slurry from the inner cavity of the tank body 21 through the mixed waste slurry extraction pipe 241, sequentially passing through the sewage pump 242 and the external pipeline 243, and fermenting in the total collection station 3 to produce biogas and farmyard manure.
In this step, the total collection station 3 controls the inner cavity of the total collection station to be negative pressure through the negative pressure adjusting mechanism B, so that the mixed waste slurry in the negative pressure assisting external pipeline 243 quickly enters the inner cavity of the total collection station 3. The working process of the negative pressure regulating mechanism B is as follows: the air pressure detecting unit B31 detects the air pressure at the upper end of the inner cavity of the main collecting station 3 in real time and controls the vacuum pump B32 to be switched off or switched on, thereby maintaining the pressure in the inner cavity of the main collecting station 3 within a certain range. When the vacuum pump B32 is started, the biogas in the inner cavity of the main collecting station 3 is pumped into a gas storage tank B33 for storage, and the gas storage tank B33 is communicated with a biogas use terminal.
