[0035] A supporting mechanism 5 is provided directly below the feeding mechanism 4, and the supporting mechanism 5 supports the bottom end of the feeding mechanism 4 and adjusts the angle of the feeding mechanism 4 within a certain range, thereby meeting the feeding of garbage and the cleaning of subsequent equipment, and improving the efficiency of the subsequent maintenance and feeding of the feeding system.

[0036] In this embodiment, the sealing cover mechanism 2 includes a rod connecting seat 21, an electric cylinder 22, a side blocking baffle 23, and a hinge 24. The rod connecting seat 21 is evenly spaced inside the transverse material guide box 44, the outer side of the rod connecting seat 21 is connected to the electric cylinder 22, the bottom end bearing of the electric cylinder 22 is connected to the side blocking baffle 23, the other side of the side blocking baffle 23 is connected to the hinge 24, and the outer side of the side blocking baffle 23 is connected to the pressure controller 7, and the side blocking baffle 23 is positioned and adjusted by the electric cylinders 22 arranged at equal intervals.

[0037] In this embodiment, the side baffle plate 23 is connected to the transverse material guide box 44 through a hinge 24 on one side, and one side of the side baffle plate 23 is positioned through the hinge 24, and the angle of the side baffle plate 23 is adjusted and controlled.

[0038] In this embodiment, the feeding mechanism 4 includes a vertical feeding hopper 41, a hydraulic cylinder 42, a side inspection port 43, a transverse material guide box 44, a drainage pipe 45 and a push block 46. A hydraulic cylinder 42 is provided on one side of the transverse material guide box 44. The top of the transverse material guide box 44 is penetrated and connected with the vertical feeding hopper 41. The output end of the hydraulic cylinder 42 is connected with a push block 46. The push block 46 is arranged inside the transverse material guide box 44. A drainage pipe 45 is penetrated and connected on one side of the transverse material guide box 44. A side inspection port 43 is opened on one side of the transverse material guide box 44. A pressure sensitive element 6 is provided on one side of the push block 46, and the liquid generated by the internal squeezing of the transverse material guide box 44 can be discharged through the drainage pipe 45.

[0039] In this embodiment, the hydraulic cylinder 42 is connected to the push block 46 via a transverse material guide box 44 installed on one side, and the hydraulic cylinder 42 pushes one side of the push block 46 to adjust the position of the push block 46.

[0040] In this embodiment, the vertical feeding hopper 41 is connected to the top of the pyrolysis gasification furnace 1 by vertically penetrating the top of the horizontal guide box 44. The domestic waste is vertically transported through the vertical feeding hopper 41 and then pushed to form a negative pressure environment.

[0041] In this embodiment, the support mechanism 5 includes a support frame 1 51, a gasket 52, a longitudinal bracket 53, a support frame 2 54 and a fastening hole 55. The interior of the support frame 1 51 is connected to the support frame 2 54, and the two side symmetry axes of the support frame 2 54 are connected to the gasket 52. The bottom end of the longitudinal bracket 53 is arranged directly above the gasket 52. Fastening holes 55 are opened at equal intervals on the outer sides of the support frame 1 51 and the support frame 2 54, and the longitudinal bracket 53 is symmetrically welded on both sides of the transverse material guide box 44.

[0042] In this embodiment, the support frame 1 51 is connected to the outer side of the support frame 2 54 through a fastening hole 55 that is opened through the support frame 1 51. The support frame 1 51 is arranged at equal intervals at the bottom end of the transverse material guide box 44, and the longitudinal bracket 53 is used to symmetrically support the equipment.

[0043] The automatic pressure regulating feeding system of the domestic waste pyrolysis equipment includes the following working processes in practical application:

[0044] Step 1: Before the equipment is used, the operator places the bottom end of the transverse material guide box 44 on the two symmetrical axes of the support frame 2 54, and connects the gaskets 52 to the two sides of the bottom end of the transverse material guide box 44, and then connects the bottom opening of the vertical feeding hopper 41 with the top of the transverse material guide box 44. The operator directly puts the domestic garbage into the interior of the transverse material guide box 44 through the vertical feeding hopper 41;

[0045] Step 2: A pressure controller 7 is installed on the side baffle plate 23 to control the electric cylinder 22. The angle of the side baffle plate 23 is controlled by adjusting the electric cylinder 22. During use, the electric cylinder 22 is rotated so that the electric cylinder 22 rotates outside the rod connecting seat 21, and the height of the electric cylinder 22 is adjusted to push the other side of the side baffle plate 23. At the same time, the other side of the side baffle plate 23 is rotated through the hinge 24 to control the angle of the side baffle plate 23, thereby controlling the size of the entrance of the inner layer of the channel;

[0046] Step 3: A pressure sensitive element 6 is provided on one side of the push block 46. The pressure detection sensitive element 6 reads the pressure of the push block at any time. After reading the pressure generated by the domestic garbage, the pressure sensitive element 6 transmits the data to the signal processing unit 8 for feedback. The electronic circuit detects this change and converts and outputs a standard measurement signal corresponding to this pressure. The signal processing unit 8 will command whether the electric cylinder 22 is opened or closed according to the pressure value set by the system. The opening or closing of the electric cylinder 22 will drive the side baffle plate 23 to realize the linkage between the push block 46 and the side baffle plate 23, thereby controlling the pressure of the push block 46 system and transmitting the measurement signal to the pressure controller 7. The pressure controller 7 converts the pressure change into an electrical signal, and then processes these signals through the electronic circuit to determine whether it exceeds the set pressure range.

[0047] If the pressure exceeds the set upper or lower limit, the controller will send a control signal, and the hydraulic pushing device of the pusher block 46 is provided with a pressure detection sensitive element 6, which transmits the data to the signal processing unit 8 in real time, and then uses the pressure controller 7 to control the thrust of the electric cylinder 22 accordingly, and adjusts the domestic waste pyrolysis feeding system to meet the requirements of the domestic waste pyrolysis feeding system, and then uses the pressure controller 7 to control the thrust of the electric cylinder 22 accordingly, and adjusts the pressure of the domestic waste to meet the pyrolysis pressure requirements of the domestic waste;

[0048] Step 4: The pressure controller 7 continuously senses the pressure change and automatically adjusts the switch state of the actuator according to the set value to maintain the fluid pressure within the set range. The side baffle 23 pushes the rod connecting seat 21 and the side baffle 23 through the electric cylinder 22 according to the instruction of the processing unit 8 to realize the automatic adjustment direction of the side baffle 23 and then adjust the size of the inlet to achieve automatic adjustment. The horizontal material guide box 44 will have garbage leachate seeping out through the oil cylinder feeding and squeezing. The leachate can be collected through the collection tank above the drainage pipe 45, and then transported to the underground or ground garbage leachate collection pool through this pipeline;

[0049] Step 5: The hydraulic cylinder 42 is pushed by the pusher block 46 connected on one side, and the pusher block 46 is used to push the garbage to the rightmost part (in the right sealed channel), and finally falls into the combustion box to be burned with liquefied gas. It is necessary to ensure that the pyrolysis gasification furnace 1 is in a negative pressure state. The squeezed garbage in the horizontal channel needs to seal the combustion box. Negative pressure is generated in the pyrolysis gasification furnace 1 and isolated from the air to form a hot distillation environment. The temperature of the pyrolysis gasification furnace 1 is controlled between 300℃ and 350℃. The garbage is decomposed into hot distillation gas, garbage slag (carbon black) and waste liquid through thermal distillation.

[0050] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
