the first extrusion plate 4 continuously rotates along with the rotating shaft 2, sludge in a space formed by the first extrusion plate 4 and the second extrusion plate 6 which rotate in the same direction as the rotating shaft 2 is continuously extruded, the pressure in the space is gradually increased, when the pressure is increased to a certain value, a safety valve at the discharge port 10 is triggered, the safety valve enables the discharge port 10 to be opened, and the treated sludge leaves the inner barrel through the discharge port 10; when the first extrusion plate 4 rotates along with the rotating shaft 2 to contact with the stop lever 27, the stop lever drives the arc plate to move along the second arc-shaped groove 23, the sixth pressure spring 31 is gradually compressed, the positioning column 25 is driven to move when the arc plate moves, the positioning column 25 moves towards the direction far away from the baffle plate 9 under the action of the inclined surface of the positioning column 25, the fifth pressure spring 30 is compressed, after the positioning column 25 moves out of the positioning hole 26, the position of the baffle plate 9 is released, the baffle plate 9 moves along the first arc-shaped groove 19 to reset under the action of the pressure of the second pressure spring 20, and the feed port 8 is closed; after the baffle 9 is separated from the positioning column 25, the positioning column 25 moves to be reset in the direction close to the baffle 9 under the pressure of the fifth pressure spring 30; when the arc plate 24 moves to the lowest end of the displacement, the first extrusion plate 4 pushes the stop lever to move outwards due to the left and right sides of the inclined surface of the stop lever, the fourth compression spring 28 is compressed, when the first extrusion plate 4 rotates to be separated from the stop lever, the stop lever moves inwards under the pressure of the fourth compression spring 28 to reset, and meanwhile, the arc plate 24 moves upwards along the second arc-shaped groove 23 under the pressure of the sixth compression spring 31 to reset.
The first extrusion plate 4 continues to rotate, the treated sludge is discharged out of the inner barrel through the discharge hole 10, after the treated sludge is discharged out of the inner barrel, the pressure is reduced, and the discharge hole 10 is closed under the action of a safety valve; when the first extrusion plate 4 continues to rotate, the first extrusion plate 4 rotates to be in contact with the stop block 14, due to the action of the inclined surface of the stop block 14, the first extrusion plate 4 extrudes the stop block 14 to move downwards, the first pressure spring 18 is compressed, after the stop block 14 moves downwards, the second extrusion plate 6 is separated from the groove 15, the rotating shaft 2 rotates to drive the second rotating block 5 to rotate under the action of the inner friction wheel 12 and the outer friction wheel 13, the second rotating block 5 rotates to drive the second extrusion plate 6 to rotate together, meanwhile, after the second extrusion plate 6 is separated from the stop block 14, the first extrusion plate 4 rotates to the groove 15, the stop block 14 moves upwards under the action of the pressure of the first pressure spring 18 to reset, the first extrusion plate 4 is placed in the groove 15, due to the contact of the side wall of the groove 15 and the first extrusion plate 4, the inner friction wheel 12 and the outer friction wheel 13 at the position of the first rotating block 3 slip, and the first extrusion plate 4 stops rotating; the second extrusion plate 6 rotates to extrude the sludge, so that the moisture of the sludge is discharged out of the inner barrel through the through hole 7; therefore, the first extrusion plate 4 and the second extrusion plate 6 rotate alternately, the feed inlet 8 is continuously opened and closed, and sludge is not extruded and dewatered.
It is worth noting that: when the feeding hole 8 is opened, the treated sludge and the sludge to be treated are simultaneously in the inner barrel, and because the first extrusion plate 4 and the second extrusion plate 6 form two different spaces, the treated sludge in the inner barrel is not discharged out of the inner barrel, the sludge to be treated is not influenced to enter the inner barrel, thereby saving time and improving efficiency; in addition, as the sludge to be treated enters the inner barrel, the force is applied to the moving extrusion plate under the action of gravity, so that the movement of the extrusion plate is more labor-saving, and the sludge dewatering device is more beneficial to the dewatering process of the sludge being treated; in addition, after the feeding hole 8 is opened, the feeding hole stays for a certain time, the length of the arc-shaped plate 24 is not too short, and when the extrusion plate moves to a position close to the discharging hole 10, the arc-shaped plate 24 moves to enable the feeding hole 8 to be closed, so that enough sludge can be ensured to enter, and the sludge treatment amount in each time can be ensured; finally, the stop 14 is arranged at a position close to the discharge hole 10, and after the extrusion plate rotates through the discharge hole 10, the extrusion plate rotates alternately, so that the treated sludge can be ensured to be completely cleaned out of the inner barrel; after the sludge is treated, the sludge still has soft texture and certain fluidity, so a special liquid safety valve can be selected, and when the pressure is lower, the automatic closing of the safety valve cannot be influenced.
According to the invention, through the matching action of the stop block 14, the groove 15, the first extrusion plate 4 and the second extrusion plate 6, the purpose that the rotating shaft 2 rotates only can drive one of the extrusion plates to rotate is realized, so that sludge is extruded, and the safety valve is arranged at the discharge hole 10, 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 and the baffle 9, the feed inlet 8 is opened after the first extrusion plate 4 or the second extrusion plate 6 rotates through the feed inlet 8, sludge to be treated falls into the inner barrel, 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 when the sludge is extruded, the time cost is saved, the complexity of operation is reduced, automation is realized, and the treatment efficiency is improved.
According to the invention, through the matching action of the baffle 9, the positioning column 25, the positioning hole 26 and the second pressure spring 20, the automatic opening of the feed inlet 8 is realized, and after the feed inlet 8 is opened for a certain time, the feed inlet 8 is closed, so that when the extrusion plate extrudes sludge, the extrusion plate rotates in front of the feed inlet 8, the feed inlet 8 is closed, the sludge is prevented from flowing out of the feed inlet 8, after the extrusion plate rotates through the feed inlet 8, the feed inlet 8 is opened for feeding, the complexity of operation is reduced, and the efficiency is improved.
