The first extrusion plate 4 continues to rotate, the treated sludge is discharged out of the inner barrel 7 through the discharge hole 14, after the treated sludge is discharged out of the inner barrel 7, the pressure is reduced, and the discharge hole 14 is closed under the action of the safety valve 15; the first extrusion plate 4 continues to rotate, when the first extrusion plate 4 rotates to be in contact with the guide rod 26 of the L-shaped rod 22, the L-shaped rod 22 is pushed to move downwards through the inclined surface, the L-shaped rod 22 drives the positioning pin 20 to move downwards, the first pressure spring 24 is compressed, the positioning pin 20 moves downwards and moves out of the positioning hole 21, the second rotating shaft 18 is loosened, the second extrusion plate 6 drives the second rotating shaft 18 to rotate under the matching of the inner friction wheel 16 and the outer friction wheel 17, after the second extrusion plate 6 rotates to be separated from the baffle plate 19, the first extrusion plate 4 is separated from the L-shaped rod 22, the positioning pin 20 drives the L-shaped rod 22 to move upwards and reset under the pressure of the first pressure spring 24, the positioning pin 20 moves into the positioning hole 21 adjacent to the previous positioning hole 21 and fixes the second rotating shaft 18 again, meanwhile, the first extrusion plate 4 is in contact with the baffle plate 19 adjacent to the previous baffle plate 19, and the position of the first extrusion plate 4 is fixed, the inner friction wheel 16 and the outer friction wheel 17 at the first extrusion plate 4 are in a slipping state, and the first extrusion plate 4 cannot rotate; the second extrusion plate 6 rotates to extrude the sludge, so that the moisture of the sludge is discharged out of the inner barrel 7 through the through hole 8; therefore, the first extrusion plate 4 and the second extrusion plate 6 rotate alternately, the feed inlet 9 is opened and closed continuously, and the sludge is extruded and dewatered continuously.
It is worth noting that: when the feeding hole 9 is opened, the treated sludge and the sludge to be treated are simultaneously in the inner barrel 7, and because the first extrusion plate 4 and the second extrusion plate 6 form two different spaces, the treated sludge in the inner barrel 7 is not discharged out of the inner barrel 7, the sludge to be treated is not influenced to enter the inner barrel 7, thereby saving time and improving efficiency; secondly, a one-way valve 12 is arranged at the feeding channel, so that the sludge can only flow into the inner barrel 7 but cannot flow reversely into the material collecting box 10 from the inner barrel 7, and the sludge cannot reversely overflow during extrusion; in addition, as the sludge to be treated enters the inner barrel 7, the force is applied to the moving extrusion plate due to the action of gravity, so that the movement of the extrusion plate is more labor-saving, and the dehydration process of the sludge being treated is more facilitated; in addition, the feeding hole 9 is opened and stays for a certain time, so the shape structure of the cam 25 is reasonably arranged, the feeding channel is opened after the extrusion plate rotates through the feeding hole 9, and the feeding channel is closed when the extrusion plate rotates to be close to the discharging hole 14, so that enough sludge can be ensured to enter, and the sludge treatment amount in each time can be ensured; finally, the second rotating shaft 18, the baffle plate 19 and the L-shaped plate are arranged at a position which is not far away from the discharge hole 14, and when the extrusion plate rotates through the discharge hole 14, the extrusion plate rotates alternately, so that the treated sludge can be ensured to be completely cleaned out of the inner barrel 7; after the sludge is treated, the sludge still has soft texture and certain fluidity, so the special liquid safety valve 15 can be selected, and when the pressure is lower, the automatic closing of the safety valve 15 cannot be influenced.
According to the invention, through the matching action of the second rotating shaft 18, the baffle plate 19, the first extrusion plate 4 and the second extrusion plate 6, the purpose that only one of the extrusion plates can be driven to rotate by the rotation of the rotating shaft 2 is realized, so that sludge is extruded, and the safety valve 15 is arranged at the discharge hole 14, so that the dehydration degree of the sludge is the same every time during sludge treatment, and the consistency of the water content of sludge dehydration is ensured.
According to the invention, through the cooperation of the first extrusion plate 4, the second extrusion plate 6, the cam 25 and the stopper 13, the feed inlet 9 is opened after the first extrusion plate 4 or the second extrusion plate 6 rotates through the feed inlet 9, sludge to be treated falls into the inner barrel 7, but the first extrusion plate 4 and the second extrusion plate 6 form different spaces, so that the sludge to be treated and the sludge being treated can not be crossed, the sludge to be treated falls into the inner barrel 7 when the sludge is extruded, the time cost is saved, the complexity of operation is reduced, the automation is realized, and the treatment efficiency is improved.
According to the invention, through the matching action of the stop block 13, the cam 25, the through hole 8 and the feeding groove, the automatic opening of the feeding channel is realized, the feeding channel is closed after the feeding channel is opened for a certain time, the feeding channel is closed when the extrusion plate extrudes sludge and the extrusion plate rotates in front of the feeding hole 9, the sludge is prevented from flowing out of the feeding channel, the feeding channel is opened for feeding after the extrusion plate rotates through the feeding hole 9, the complexity of operation is reduced, and the efficiency is improved.
