through the setting of keeping off shell 27, avoid the filth of gathering under cartridge filter 4, and through the effect of keeping off shell 27 to third swinging arms 18, guarantee that third swinging arms 18 is in the tilt state all the time, be favorable to third swinging arms 18 to promote to the downside smoothly, avoid taking place the condition of jamming.
The working principle is as follows:
firstly, wastewater to be treated is led into the accommodating space 2 through the lead-in opening 3, the wastewater in the accommodating space 2 is purified by a conventional biological reaction mode, a large amount of methane is generated in the purification process, the generated methane rises and accumulates in the cover body 51 at the upper end of the accommodating space 2 because the methane density is less than that of air, the cover body 51 is jacked up after accumulating a certain volume, after the cover body 51 is jacked up for a certain distance, the methane in the cover body 51 is communicated through the step groove 7 and is discharged outwards through the step groove 7, after the cover body 51 rises, the space at the upper end of the accommodating space 2 is reduced, therefore, the water pressure entering the accommodating space 2 through the lead-in opening 3 is gradually increased, and then turbulent flow is formed in the accommodating space 2 through the increase of the water pressure, so that the microorganisms for purification and organic matters in the liquid can be fully and quickly combined, improve purification rate, and through the impact effect of vortex, play the impact cleaning action to the lateral surface of cartridge filter 4, avoid cartridge filter 4 surface to gather too much suspended solid and influence the filter effect.
The embodiments of the present invention are disclosed as the preferred embodiments, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention and make various extensions and changes without departing from the spirit of the present invention.
