The technical scheme of the invention is as follows: the automatic collecting and conveying method of the kitchen and toilet waste slurry is applied to the automatic collecting and conveying system of the urban and rural kitchen and toilet waste slurry, and comprises the following steps:

s01, collecting kitchen garbage and toilet excrement respectively, and then uniformly discharging the collected garbage and excrement into a sediment deposition cavity of a building pool body, wherein large garbage is intercepted by a net bag and retained in the net bag, after the cleaning is unified by workers in the future, the rest part falls into the sediment deposition cavity through the net bag, small garbage with higher density in the rest part is sunk into the bottom of the sediment deposition cavity, after the fishing is unified by the workers in the future, kitchen and toilet waste pulp in the rest part flows into a mixed waste pulp containing cavity through meshes in a grid plate, and when the mixed waste pulp in the mixed waste pulp containing cavity is deposited to a certain liquid level height, the mixed waste pulp is automatically discharged through a mixed waste pulp output pipe;

in the step, the opening and closing control mechanism of the pipe orifice of the building pool body controls the opening or closing of the pipe orifice of the mixed waste slurry output pipe, so that the mixed waste slurry in the inner cavity of the building pool body is automatically discharged; the working principle of the pipe orifice opening and closing control mechanism is as follows:

a. when the device is in an initial state, the amount of mixed waste slurry in the inner cavity of the building pool body is less, along with accumulation of the mixed waste slurry in the mixed waste slurry containing cavity, the liquid level in the inner cavity of the building pool body is continuously lifted until the liquid level overflows the floating ball A, the long arm of the lever tends to rotate upwards, and the lower edge of the limiting plate is abutted against the pulley, so that the long arm of the lever is limited to rotate upwards;

b. along with further accumulation of mixed waste slurry in the mixed waste slurry containing cavity, the liquid level in the inner cavity of the building pool body is further lifted, so that the floating ball B is synchronously lifted along with the liquid level, when the liquid level in the inner cavity of the building pool body reaches a preset liquid level, the floating ball B tensions the rope B under the action of buoyancy generated by the floating ball B, the tension of the rope B overcomes the elasticity of the spring, the pulley seat is pulled to move in the direction away from the lever, and the pulley is further separated from the lower edge of the limiting plate;

c. when the pulley is separated from the lower edge of the limiting plate, the long arm of the lever immediately rotates upwards under the action of buoyancy provided by the floating ball A, so that the rope A is tightened, the cover plate rotates to be in a horizontal state under the traction of the rope A, a pipe orifice at one end of the mixed waste slurry output pipe, which is positioned in the mixed waste slurry containing cavity, is opened, and the mixed waste slurry in the mixed waste slurry containing cavity is immediately discharged through the mixed waste slurry output pipe;

d. the rope B is loosened along with the descending of the liquid level, the pulley seat loses the tensile force of the rope B, and gradually moves towards the direction close to the lever under the elastic force action of the spring, meanwhile, the floating ball A drives the long arm of the lever to rotate downwards along with the descending of the liquid level, so that the rope A is loosened, the cover plate loses the tensile force of the rope A and then rotates downwards under the action of self gravity to cover the pipe orifice of the mixed waste slurry output pipe, so that the pipe orifice of one end, positioned in the mixed waste slurry containing cavity, of the mixed waste slurry output pipe is closed, and finally, the pulley moves to a state of being in contact with the lower edge of the limiting plate;

e. the steps a to d are repeated, so that the automatic discharge of the mixed waste slurry in the mixed waste slurry containing cavity is realized;

s02, after the mixed waste slurry is discharged from the mixed waste slurry output pipe, the mixed waste slurry is sucked into the mixed waste slurry input pipe through a pipeline under the negative pressure action of the inner cavity of the pool body and then is sucked into the inner cavity of the pool body, and after the mixed waste slurry in the inner cavity of the pool body is accumulated to a certain liquid level height, the mixed waste slurry is automatically discharged through the mixed waste slurry extraction pipe;

in the step, the pool body is controlled by a negative pressure adjusting mechanism A to keep the negative pressure in the inner cavity of the pool body at 0.15-1.5 kg/cm²Then the mixed waste slurry discharged from the mixed waste slurry output pipe by the negative pressure assistance quickly enters the inner cavity of the pool body; the working process of the negative pressure regulating mechanism A is as follows: the air pressure detection unit A detects the air pressure at the upper end of the inner cavity of the pool body in real time; when the liquid level in the inner cavity of the community pool body rises to cause the volume of the inner cavity of the community pool body to be reduced, the pressure of the inner cavity of the community pool body is increased, and the air pressure detection unit A detects that the pressure in the inner cavity of the community pool body is increased to exceed the preset upper limit value, the vacuum pump A is started immediately, part of air in the inner cavity of the community pool body is pumped out and stored in the air storage tank A, and therefore the pressure in the inner cavity of the community pool body 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 community pool body is reduced to cause that the pressure in the inner cavity of the community pool body is reduced to be lower than a preset lower limit value, an electric control valve on a pipeline connected to an exhaust port of a gas storage tank A is opened, gas stored in the gas storage tank A is input into the inner cavity of the community pool body through the pipeline under the action of negative pressure in the inner cavity of the community pool body, and the pressure in the inner cavity of the community pool body is increased to 0.15-1.5 kg/cm²The content of the compound is less than the content of the compound;

in the step, the pool body controls the mixed waste slurry in the inner cavity of the pool body to be automatically discharged through a mixed waste slurry extracting pipe through a mixed waste slurry extracting mechanism; the working process of the mixed waste slurry pumping mechanism is as follows: along with more and more mixed waste slurry accumulated in the inner cavity of the pool body, the liquid level of the mixed waste slurry is also lifted continuously, when the high liquid level calibrated by the high liquid level detection unit is reached, the sewage pump is started, the waste slurry in the inner cavity of the pool body is pumped out through the mixed waste slurry pumping pipe, the liquid level in the inner cavity of the pool body is immediately lowered, and when the low liquid level calibrated by the low liquid level detection unit is reached, the sewage pump is closed;

s03, discharging the mixed waste slurry from the inner cavity of the pool body through a mixed waste slurry extraction pipe, sequentially passing through a sewage pump and an external pipeline, and fermenting in a total collection station to produce biogas and farmyard manure;

in the step, the total gathering station controls the inner cavity of the total gathering station to be negative pressure through a negative pressure adjusting mechanism B, so that the mixed waste slurry in the negative pressure assisting external pipeline quickly enters the inner cavity of the total gathering station; the working process of the negative pressure regulating mechanism B is as follows: the air pressure detection unit B detects the air pressure at the upper end of the inner cavity of the total collection station in real time and controls the vacuum pump B to be turned off or turned on, so that the pressure in the inner cavity of the total collection station is maintained within a certain range; when the vacuum pump B is started, methane in the inner cavity of the main collection station is pumped into the gas storage tank B for storage, and the gas storage tank B is communicated with a methane use terminal.

Compared with the prior art, the invention has the following advantages:

1. the system can realize efficient, environment-friendly and automatic collection of waste pulp of kitchens and toilets in residential areas, office buildings and commercial buildings, and uniformly convey the waste pulp to a gathering station for further treatment;

on one hand, the collection and conveying process of the kitchen and toilet waste pulp does not need manual transportation, so that the cost (manpower and material resources) is reduced;

on the other hand, the collecting and transporting process of the kitchen and toilet waste pulp is in a closed chamber or pipeline and is not in contact with the external environment, so that the environmental pollution is avoided, and mosquito and bacteria propagation is avoided;

on the other hand, the characteristics that the kitchen and toilet waste pulp is rich in nitrogen, phosphorus and potassium elements and easy to ferment are fully considered, the kitchen and toilet waste pulp is uniformly collected to a general gathering station (methane tank) to produce methane and farmyard manure, the waste pulp is recycled, and the loss of the nitrogen, phosphorus and potassium elements is effectively prevented.

2. The mixed waste slurry in the inner cavity of the building pool body is automatically discharged through the pipe orifice opening and closing control mechanism, and the pipe orifice opening and closing control mechanism realizes that the cover plate can be automatically opened to discharge the mixed waste slurry through the lever limiting assembly when the liquid level in the inner cavity of the building pool body reaches the preset height (the principle is that when the liquid level in the inner cavity of the building pool body does not reach the preset height, the lower edge of the limiting plate is in contact with the pulley, so that the long arm of the lever is limited to rotate upwards, when the liquid level in the inner cavity of the building pool body reaches the preset height, the rope B is tightened under the buoyancy of the floating ball B, so that the pulley seat is pulled by a pulling force to move towards the direction far away from the lever, the pulley is separated from the lower edge of the limiting plate, the long arm of the lever immediately rotates upwards under the buoyancy of the floating ball A, and the cover plate is opened by. Therefore, the liquid level of the inner cavity of the building tank body is in a higher state when mixed waste slurry is discharged each time. The waste slurry discharged at a high liquid level can have a certain pressure when being discharged, so that the discharge speed of the waste slurry is accelerated, and the slow flowing and the stagnation of the waste slurry in the mixed waste slurry output pipe are prevented.

Briefly describing the working process of the invention:

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.

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, the mixed waste slurry discharged from the mixed waste slurry outlet pipe 14 by the negative pressure assist force rapidly enters the inner chamber of the waste tank 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 tank body 21 rises to cause the volume of the inner cavity of the tank body 21 to be reduced, the pressure in the inner cavity of the tank body 21 is increased, and the air pressure detection unit A221 detects that the pressure in the inner cavity of the tank body 21 is increased to the valueWhen the pressure exceeds the preset upper limit value, the vacuum pump A222 is started immediately to pump out a part of air in the inner cavity of the tank body 21 and store the air in the air storage tank A223, so that the pressure in the inner cavity of the tank 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.
