s2: the step motor 7 works to drive the collecting frame 6 of the collecting frame 6 to rotate, meanwhile, the clamping plate 11 starts to rotate towards the direction of the collecting frame 6, mud on the mud filter plate 12 is compressed, and meanwhile, the collecting frame 6 is closed, so that the mud is prevented from overflowing in the rotating process of the collecting frame 6;
s3: along with the rotation of the rotating plate 9, the driving gear 27 on the collecting frame 6 starts to rotate under the meshing action of the fixed gear 26, so as to drive the screw rod 36 to rotate, the screw rod 36 further drives the bolt 40 to rotate, so that the bolt 40 beside the collecting frame 6 rotates clockwise towards the extending plate 39, the bolt 40 can be screwed into the extending plate 39, and the distance between the clamping plate 11 and the collecting frame 6 is further shortened;
s4: the clamping plate 11 further compacts the sludge to remove water in the sludge;
s5: the bolt 40 starts to rotate anticlockwise along with the rotation of the collecting frame 6, the bolt 40 is separated from the extension plate 39, then the clamping plate 11 starts to rotate towards the direction far away from the collecting frame 6, the clamping plate 11 is separated from the collecting frame 6, and the dewatered mud cake falls to the mud cake guiding box 5 to wait for the next treatment.
The working principle is as follows: the stepping motor 7 drives one set of rotating plates 9 to rotate, and drives the other set of rotating plates 9 to rotate through the plurality of sets of supporting rods 14, so that the two sets of rotating plates 9 can be driven to synchronously rotate.
As shown in fig. 3-7, when two sets of rotating plates 9 rotate, a plurality of sets of collecting frames 6 fixedly connected with the rotating plates 9 are driven to rotate, when one set of collecting frame 6 rotates to the horizontal direction, a discharge port of the waste slurry injects a proper amount of slurry into the collecting frame 6, then, along with the rotation of the collecting frame 6, the sliding block 8 on the linkage rod 16 gradually slides to the protrusion part of the cam disc 15, further, the clamping plate 11 is driven to start to rotate towards the direction of the collecting frame 6, the sludge on the silt filter plate 12 is compacted, simultaneously, the collecting frame 6 is closed, further, the slurry is prevented from overflowing in the rotating process of the collecting frame 6, when the collecting frame 6 rotates to the lower part of the rotating plates 9, the sliding block 8 on the linkage rod 16 gradually slides to the concave part of the cam disc 15, further, the clamping plate 11 is driven to start to rotate towards the direction far away from the collecting frame 6, so that the mud cake can be discharged smoothly and the collecting frame 6 can enter the next treatment cycle.
Because the one end that L shape backup pad 13 was kept away from to connecting tube 22 communicates with the inside of circular rotation cavity 23, when suction pump 4 during operation, can form the negative pressure in the inside of circular fixed cavity 24 and circular rotation cavity 23, and then can form the negative pressure in the below of silt filter 12, further accelerate the separation efficiency of moisture and mud sediment in the mud, clear water after being filtered can be collected by suction pump 4 suction, make the clear water can reuse, environmental protection more.
As shown in fig. 11-17, when the clamping plate 11 and the collecting frame 6 are closed, the rotating plate 9 will continue to rotate, the driving gear 27 on the collecting frame 6 starts to rotate under the meshing action of the fixed gear 26, and then the crank connecting rod 33 is driven to rotate, and the crank connecting rod 33 continues to drive the driving block 38 to move along the screw rod 36 through the pushing rod 34, and then the screw rod 36 is driven to rotate.
When the lead screw 36 rotates, the bolt 40 is further driven to rotate, so that the bolt 40 beside the collecting frame 6 rotates clockwise towards the direction of the extending plate 39, the bolt 40 can be screwed into the extending plate 39, the distance between the clamping plate 11 and the collecting frame 6 is further shortened, the pressure applied to mud residue by the clamping plate 11 and the collecting frame 6 is improved, and the treatment effect of the device on mud with high sediment content is further improved.
The bolt 40 starts to rotate anticlockwise along with the rotation of the collecting frame 6, the bolt 40 is separated from the extension plate 39, then the clamping plate 11 starts to rotate towards the direction far away from the collecting frame 6, the clamping plate 11 is separated from the collecting frame 6, and the dewatered mud cake falls to the mud cake guiding box 5 to wait for the next treatment.
It should be noted that:
1. the cooperation design of pinch-off blades 11 and silt filter 12 can be regarded as a plurality of groups of little sheet frames, and the size of every group of little sheet frame can be customized according to the engineering demand.
2. The pressure adjustment range between the clamping plate 11 and the silt filter plate 12 is 1MPa-5 MPa.
3. The filter pressing efficiency can be adjusted by adjusting the rotating speed of the rotating plate 9, and when the rotating speed is accelerated, the water content of the filter-pressed mud cake is high, but the mud treatment efficiency is high; similarly, when the rotation speed is slowed down, the water content of the press-filtered mud cake is low, and accordingly, the efficiency of treating mud is reduced.
4. The rotating plate 9 is circular in the figure, and can be made into other shapes according to the actual engineering requirements, such as a caterpillar elliptical shape, and correspondingly, the number of the small plate frames of the clamping plate 11 and the sediment filter plate 12 can also be increased along with the change of the shape of the rotating plate 9.
5. Each part of the invention is modularized, and is convenient for quick installation, disassembly and replacement.
6. The filter cloth on the silt filter plate 12 of the invention is replaceable, and the filter cloth with different adaptive large and small holes can be replaced according to the soil particles with different sizes in the slurry.
7. The invention can also arrange a detachable braking wheel at the bottom, which is convenient for rapidly moving the whole device.
The above examples only show two embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
