The working principle or the using method is as follows:
when the device is in normal operation, namely in an initial state, the water pump 12 is in normal operation, clean water is obtained after the sewage in the membrane treatment tank 1 is filtered by the MBR module 11 and discharged, the impeller is rapidly rotated at the moment, so that larger electric energy is generated, the electromagnet 122 generates larger suction force to adsorb the first bevel gear 1211, the first elastic piece 123 is compressed at the moment, along with the increase of the service time of the device, the sludge concentration in the membrane treatment tank 1 is increased, meanwhile, the MBR module 11 is adhered by sludge, so that the efficiency of water filtration is influenced, the water amount pumped by the water pump 12 is reduced, the water amount passing through the impeller is reduced, the rotation of the impeller is reduced, the magnetism of the electromagnet 12 is reduced, the first shaft 121 is forwards slid under the action of the first elastic piece 123, the first bevel gear 1211 on the first shaft 121 is meshed with the second bevel gear 321 on the transmission shaft 32, and the water pump 12 is enabled to drive the transmission shaft 32 to rotate.
The suction pump 12 drives the circulation guide shaft 22 to rotate through the transmission shaft 32 so as to drive the compression plate 21 to slide downwards, in the process of sliding downwards, the cleaning opening 211 of the compression plate 21 enters the MBR module 11, a fine brush is arranged on the cleaning opening 211, cleaning of the surface of the MBR module 11 is completed in the process of moving downwards, and as the section of the compression plate 21 is consistent with that of the membrane treatment pool 1, after the compression plate 21 falls into the MBR module 11, the space below the compression plate 21 is in a closed state, sewage below the compression plate is subjected to pressure treatment in the process of continuing to fall, the sewage enters the water permeable opening 2131 through the MBR membrane under the action of pressure, and is sprayed out from the cleaning opening 211, so that the MBR module 11 is cleaned and washed, and the sludge below the compression plate 21 is gradually pressed dry, and the water flows back to the upper part of the compression plate 21.
The upper end surface of the inner cavity of the membrane treatment tank 1 is provided with a press contact switch, the compression plate 21 is pressed against the press contact switch in an initial state, the press contact switch controls the circuit between the electromagnet 122 and the power generation device to be smooth, and when the compression plate 21 moves downwards, the press contact of the press contact switch disappears, so that the electromagnet 122 and the power generation device are disconnected at the moment, and only when the compression plate 21 returns to the initial position again, the electromagnet 122 and the power generation device can be connected, so that in the next cycle movement process of the compression plate 21, even if the water yield is restored to the initial state, the first shaft 12 is always connected with the transmission shaft 32.
When the bottom plate 51 moves to the lowest end, namely, the squeezing of sewage is completed at this time, the first magnetic block 214 in the compression plate 21 adsorbs the second magnetic block 216 positioned at the bottom of the guide post 23, at this time, most of the dried sludge and sundries are positioned in the transit tank 4, at this time, the circulation guide shaft 22 continues to rotate, and starts to move upwards under the action of the circulation slideway 221, so as to drive the second magnetic block 216 to lift up together, thereby pulling the bottom plate 51 to open, in the opening process, the notch of the grid bottom plate 13 is automatically closed, the sewage in the membrane treatment tank 1 does not enter the transit tank 4 any more, the bottom plate 51 is opened, the sludge squeezed in the transit tank 4 before automatically falls into the sludge tank 5, when the rear end of the bottom plate 51 is propped against the rear wall of the second sliding cavity, the compression plate 21 continues to move upwards, so that the magnetic attraction connection between the first magnetic block 214 and the second magnetic block 216 is disconnected, the bottom plate 51 is propped against the front end of the second sliding cavity again under the action of the third elastic piece 511, and simultaneously pushes the top contact block 52 to move forwards, and the pull rope 522 is pulled forwards, and the baffle plate 132 is opened by the action of the second notch is pulled forwards.
In the process of upward movement of the compression plate 21, since the upper pressure of the compression plate 21 is greater than the lower pressure, the upper sewage pressure turning plate 213 turns downward, so that the through hole 212 is opened, sewage enters from the through hole 212 to the lower side of the compression plate 21, and simultaneously the compression plate 21 can move upward, and when moving to the uppermost end, the compression plate is pressed against the press switch, so that the magnet 122 is communicated with the power generation device, and at the moment, the MBR module 11 is cleaned, meanwhile, the sludge in the membrane treatment tank 1 is also treated, and therefore, the water volume pumped by the water pump 12 is restored to the initial state, and the electromagnet 122 adsorbs the first bevel gear 1211 again, so that the cleaning is finished.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
