The principle and the application method of the invention are as follows:
when residents want to treat kitchen waste, the classified kitchen waste is filled into degradable plastic bags, the plastic bags are directly put into the vertical waste pipeline 1 from the waste putting opening 2 of the corridor opening, and the kitchen waste is continuously accumulated at the bottom of the vertical waste pipeline 1 along with the continuous input of the waste into the vertical waste pipeline 1. The ventilation opening 6 at the top of the vertical garbage pipe 1 continuously discharges the pungent gas in the vertical garbage pipe 1, so that the influence of the pungent gas on residents throwing garbage at the garbage throwing opening 2 is reduced.
Before cleaning kitchen waste stored in the vertical waste pipe 1, the kitchen waste collecting box 13 is placed on the weighing mechanism 16, so that a preset value of the hydraulic pressure sensor 27 is set according to the pressure received by the hydraulic weight detecting mechanism corresponding to each carriage wheel 15 when the kitchen waste collecting box 13 is actually fully loaded, and because the kitchen waste collecting box 13 has a complex structure, the position of each carriage wheel 15 is stressed differently when fully loaded, and therefore, the preset value of the hydraulic pressure sensor 27 at the corresponding position needs to be adjusted according to the state of each carriage wheel 15 when fully loaded. When the hydraulic pressure sensor 27 corresponding to the carriage wheel 15 reaches a preset value, the electronic control system controller PLC will send out a full box signal. After a predetermined value of each carriage wheel 15 is set, hydraulic oil is filled through the oil filling port 25, and meanwhile, the oil outlet 26 is opened, so that the lifting rod 13 is pushed to lift out of the top cover plate 19 to be flush with the carriage guide rail 18.
At this time, the carriage wheel 15 of the kitchen waste collection box 13 is in contact with the top cover plate 19 of the weighing mechanism 16, and meanwhile, due to the existence of the front stop block 29 and the rear limiting block 30, the kitchen waste collection box 13 will not move, and at this time, the feed inlet of the kitchen waste collection box 13 corresponds to the discharge outlet of the gas-solid separator 8.
When kitchen waste in the vertical waste pipeline 1 is accumulated to a certain degree, the central control system receives a signal that the waste in the vertical waste pipeline 1 is full, then controls the vacuum high-pressure fan 9 to start working, and forms negative pressure in the pipeline system of the whole set of receiving and transporting device, so that pressure difference is formed between the inside and the outside of the horizontal waste pipeline 4, and air is sucked into the horizontal waste pipeline 4 from the air control valve 7 at the tail end of the horizontal waste pipeline 4. Then the discharge valve 5 of the discharge port valve and the discharge valve 12 of the gas-solid separator 8 are controlled to be opened, kitchen waste stored in the vertical waste pipeline 1 is sucked into the horizontal waste pipeline 4, meanwhile, the kitchen waste enters the gas-solid separator 8 under the driving of sucked air, the kitchen waste is separated from the gas through the operation of the gas-solid separator 8, the kitchen waste enters the kitchen waste collecting box 13 from the discharge port of the gas-solid separator 8, the gas is output from the gas outlet of the gas-solid separator 8 and is sucked into the air purifier 11 by the vacuum high-pressure fan 9, and the silencer 10 is arranged on the gas pipeline of the air purifier 11 between the vacuum high-pressure fan 9 and the air purifier, so that noise can not be generated in the gas purifying process, the life of residents can not be influenced, and the purified gas is directly discharged into the atmosphere without damaging the environment.
When more and more kitchen wastes enter the kitchen waste collecting box, as the carriage wheels 15 directly act on the weighing mechanism 16, the pressure born by the hydraulic weight detecting mechanism is gradually increased along with the continuous increase of the weight of the kitchen waste collecting box 13, the numerical value of the hydraulic pressure in the hydraulic weight detecting mechanism detected by the hydraulic pressure sensor 27 is continuously increased, when the numerical value reaches a preset pressure value, the fact that the top cover plate 19 corresponding to the carriage wheels 15 has reached the full-load position is explained, and the hydraulic pressure sensor 27 transmits in-place signals to the electric control system controller PLC.
When the electric control system controller PLC receives in-place signals transmitted by any three or more hydraulic pressure sensors 27, the electric control system controller PLC controls the full-carriage audible and visual alarm to send out full-carriage audible and visual signals, an operator receives the full-carriage signals, the discharging valve 12 of the gas-solid separator 8 is closed, and the kitchen waste collecting box 13 is stopped from being charged. Meanwhile, the PLC uploads information to the upper computer, the upper computer uploads full-tank signals to the sanitation intelligent management system through the Internet, the system carries out transportation on the kitchen waste collection tanks which are full of the tanks through the network vehicle management and dispatching platform, before transportation, the electric control system controller PLC arranged on the kitchen waste collection tanks 13 is disconnected from the power supply and the circuit of the hydraulic pressure sensor 27, then the kitchen waste collection tanks 13 of the empty tanks are transported, other vehicles are dispatched to transport the kitchen waste collection tanks 13 of the empty tanks to the weighing mechanism 16 again, the electric control system controller PLC on the kitchen waste collection tanks 13 is connected with the power supply and the circuit of the hydraulic pressure sensor 27 again, and the discharging valve 12 of the gas-solid separator 8 is opened, and charging work is carried out again until all kitchen waste in the vertical waste pipeline 1 is cleaned. After the kitchen waste is cleaned, the discharge valve 5, the vacuum high-pressure fan 9, the air purifier 11 and the discharge valve 12 of the gas-solid separator 8 are closed, and the next cleaning is waited.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
