When the impurities in the filter disc 6 are excessive and after the liquid in the filter shell 1 is discharged, no liquid exists in the filter shell 1, the impurities in the filter disc 6 are conveniently sucked into the drum 5 by the action of the communicating pipe 10 through the suction force of the suction fan 9 by starting the suction fan 9, the impurities in the drum 5 can be intercepted at the position of a discharge hole through the filter screen 11, and the air permeability of the filter disc 6 can be recovered by cleaning the impurities in the filter disc 6, so that the filtering efficiency of the filter disc 6 is effectively improved;
When the pushing plate 26 on the sliding block 24 moves to the right, the pushing plate 26 drives the piston on the second push rod 41 to move in the second air outlet tube 40, the air generated by the second air outlet tube 40 enters the second shunt tube 43 through the second exhaust tube 42, the air in the second shunt tube 43 blows the air into the filter tank 3 through a plurality of second air outlet tubes 44 on the second shunt tube 43, and the blown air is positioned between the two filter discs 6, so that the filtering efficiency of the filter discs 6 is improved, the filtering resistance is reduced, the accumulation of dregs is prevented, the fluidity of liquid is improved, and the pushing plate 26 moves back and forth along the reciprocating threads 23 in the process, so that the second air outlet tube 40 is continuously air outlet;
When the gas in the first gas outlet tube 29 flows in the first shunt tube 32, part of the gas flow in the first shunt tube 32 is conveniently introduced into the gas blowing tube 47 through the gas collecting tube 46, the gas flow is conveniently blown to impurities on the filter disc 6 through the gas outlet of the gas blowing tube 47, the blown impurities can directly fall into the collecting tank 4, and the impurities on the filter disc 6 are cleaned in advance through the gas flow, so that the effect of scraping the impurities by the scraper 2 on the filter disc 6 is effectively improved;
When the inside impurity of filter disc 6 is too much, when there is not liquid in filtering shell 1 at this moment, through the suction of start-up extraction air exhauster 9 in the subassembly, through the suction of air exhauster 9, utilize the effect of communicating pipe 10 to be convenient for inhale the inside of rotary drum 5 with the impurity that is in filter disc 6 to the inside impurity of rotary drum 5 can be in the position of bin outlet through the interception of filter screen 11, through clear up the impurity of filter disc 6 inside, can resume filter disc 6 gas permeability, improve the filtration efficiency of filter disc 6 effectively.
In this technical scheme, the inner structure of first venthole 29 and second venthole 40 is the same with the inner structure of inflator to all be provided with the intake pipe on first venthole 29 and the second venthole 40, all be provided with the check valve in intake pipe and the first outlet duct 33, the second outlet duct 44, avoid the phenomenon that the air current in the gas pipeline appears flowing backward, be provided with the check valve on the gas collecting tube 46, be provided with the valve of definite value on the gas-blowing pipe 47 one, utilize the valve of definite value to be convenient for the gas-blowing pipe 47 can intermittently blow gas to filter disc 6, because valve of definite value, inflator and check valve are the technique that is well known in the art, do not make specific details here.
In this technical scheme, the pushing plate 26 moves reciprocally along the sliding block 24 on the reciprocal screw thread 23, the first air outlet tube 29 and the second air outlet tube 40 are intermittent when exhausting air, and the filter screen 11 on the filter disc 6 is exactly in the same vertical direction with the vent 35 when exhausting air through the vent 35 by the first air outlet tube 29.
The standard parts used in the invention can be purchased from market, and can be customized according to the description of the specification and the drawings, the specific connection modes of the parts adopt conventional means such as mature bolts, rivets, welding and the like in the prior art, the machines, the parts and the equipment adopt conventional models in the prior art, the control modes are automatically controlled by the control unit, the control circuit of the control unit can be realized by simple programming of a person skilled in the art, and the control modes and circuit connection are not explained in detail in the invention.
