The vacuum pump 13 pumps the gas in the gas sterilizing tank 8 to form vacuum, and then the pressure in the pumping tank 3 is reduced through the negative pressure main pipe 9 to form negative pressure, so that the connecting pipe 2 can realize negative pressure pumping.
The solid-liquid separation device can separate the extracted waste liquid, in this embodiment, the solid-liquid separation device includes a solid-liquid separation box 16 and a solid-liquid collection box 17, the top of the solid-liquid separation box 16 is provided with a feed inlet 1601, the feed inlet 1601 is in through connection with the extraction tank 3, and the bottom surface of the solid-liquid separation box 16 is a filter plate 1602.
The solid-liquid separation tank 17 is L-shaped, the solid-liquid separation tank 16 is clamped above the solid-liquid separation tank 17, and a solid collecting cavity 1701, a solid discharging cavity 1702 and a liquid collecting cavity 1703 are arranged inside the solid-liquid separation tank 17. The liquid collection chamber 1703 is disposed with an upper end open, and the liquid collection chamber 1703 is located directly below the filter plate 1602. The solid collecting chamber 1701 is disposed at one end of the solid-liquid separation tank 16 in the longitudinal direction, and is connected with the solid collecting chamber through a rectangular through hole, the inside of the rectangular through hole is provided with a turning plate 23, and the rotation driving device 27 controls the turning plate 23 to rotate.
The shape of the turning plate 23 is the same as that of the through hole, a rotating shaft is arranged in the center of the end face of the turning plate 23, the rotating shaft penetrates into the inner wall of the solid-liquid separation box 16, and one rotating shaft is connected with an output shaft of the rotary driving device 27. In the vertical state of the flap 23, the through hole is blocked, and the solid collecting chamber 1701 and the inside of the solid-liquid separation tank 16 are isolated from each other.
The solid discharge cavity 1702 is arranged below the solid collection cavity 1701 in a penetrating way, a detachable sealing door 18 is arranged on the outer wall of the solid discharge cavity 1702, a liquid discharge pipe 21 which is connected with the solid discharge cavity 1703 in a penetrating way is arranged outside the liquid collection cavity 1703, and a water pump 22 is connected on the liquid discharge pipe 21 in series.
The solid-liquid separation tank 16 is internally provided with a squeeze plate 28 which slides along the length direction thereof. The squeeze plate 28 is fixedly connected with the sliding part of the linear module 29 above the squeeze plate, and the linear module 29 is fixedly connected with the top surface of the inner cavity of the solid-liquid separation box 16.
The bottom surface of the extrusion plate 28 is abutted with the filter plate 1602, two vertical side surfaces of the extrusion plate 28 are abutted with the inner wall of the solid-liquid separation tank 16, and the linear module 29 adopts an electric linear module which drives the extrusion plate 28 to move along the length direction of the solid-liquid separation tank 16. In the solid-liquid separation, the waste liquid flows into the solid-liquid separation tank 16 through the inlet 1601, and the flap 23 is in a vertical state. Then the extrusion plate 28 moves towards the direction of the turning plate 23, liquid is dripped into the liquid collecting cavity 1703 through the filter plate 1602, the solid is pushed by the extrusion plate 28 to move towards the direction of the turning plate 23 until being extruded between the turning plate 23 and the extrusion plate 28, at this time, the solid-liquid separation work is completed, and the moisture contained in the solid is extruded under the action of the extrusion force, so that the solid-liquid separation effect is optimized.
After the solid-liquid separation is finished, the extrusion plate 28 moves backwards, the turning plate 23 rotates, and when the turning plate 23 rotates, the bottom surface of the turning plate is always in contact with the side surface of the extrusion plate 28, which corresponds to pushing the extrusion plate 28 to move backwards until the turning plate rotates by 90 degrees. In this process, solids between the expression plate 28 and the flap 23 may be scraped from the expression plate 28 onto the flap 23 and then transferred into the solids collection chamber 1701 as the flap 23 rotates.
Since the final solid-liquid separation is achieved by extrusion, the solid extruded on the flap 23 is easily attached to the flap 23, and the flap rotated 180 ° is sometimes difficult to fall down by itself only by the gravity of the solid. In order to solve this technical problem, in this embodiment, an air jet pipe 24 is disposed at the top of the solid collecting cavity 1701, two air exhaust holes are disposed on the air jet pipe 24, the air jet pipe is a first air hole 2401 and a second air hole 2402, the first air hole 2401 is horizontally disposed and jets air towards the top of the turning plate 23, the second air hole 2402 is obliquely disposed downwards, and an included angle between an axis of the second air hole 2401 and an axis of the first air hole 2401 is 15 ° -35 °, so that the air jets of the two air holes can blow down the solid on the turning plate 23 and blow into the solid discharging cavity 1702. So that when the flap 23 is rotated again, solids in the solids collection chamber 1701 are not re-entrained into the solids-liquid separator tank 16.
An air pump 19 is arranged outside the solid-liquid collecting box 17, and an air outlet of the air pump 19 is communicated with an air ejector tube 24 through an air pipe 20.
After separation of the liquid and solid, a portion of the gas may volatilize inside the solid discharge chamber 1702 and the liquid collection chamber 1703, which may also carry germs. In order to avoid environmental pollution during the process of discharging the liquid and the solid, in this embodiment, the outside of the solid collecting cavity 1701 is connected with the second negative pressure branch pipe 12 in a penetrating way, the outside of the liquid collecting cavity 1703 is connected with the first negative pressure branch pipe 11 in a penetrating way, the first negative pressure branch pipe 11 and the second negative pressure branch pipe 12 are respectively connected with two inlets of the three-way valve 10 in a penetrating way, and an outlet of the three-way valve 10 is connected with the gas sterilizing tank 8 or the negative pressure main pipe 9 in a penetrating way through a pipeline.
Before the waste is discharged, the vacuum is firstly pumped, the internal gas is pumped into the gas sterilizing tank 8, the volatilized gas is collected and sterilized, and the leakage of bacteria and viruses is reduced to the greatest extent.
If the inlet 1601 continues to discharge into the solid-liquid separation tank 16 after the stripper plate 28 slides past the inlet 1601, this waste stream will run off the side of the stripper plate 28 facing away from the flap 23 and the liquid will be filtered, but the solids will not be transported into the solids collection chamber 1701.

At this time, the pressing plate 28 continues to move forward, the slide plate 25 is blocked from moving, the shutter 26 rotates against the torsion force of the torsion spring until the bottom surface thereof is higher than the bottom surface of the escape area 2801, the pressing plate 28 passes, and then the shutter 26 is restored to the vertical state. When the extrusion plate 28 moves backward, the baffle 26 and the sliding plate 25 are driven to move backward until the feeding hole 1601 is opened, and then the baffle 26 is extruded to rotate, so as to pass through the baffle 26.
