[0016] Method for using a multi-layer vibrating screen wet material dredging device based on wet material screening,

When the friction reduction assembly shakes as a whole, the wire rope fits with the inner side of the wear-resistant ring, and the wire rope is fixed, and the wire rope scrapes the wet material blocked inside the wear-resistant ring and the double-column material discharge column;

[0018] S2: When the anti-friction assembly shakes as a whole, to prevent the steel wire rope from causing the sieve hole to increase due to friction with the anti-friction assembly, when the anti-friction assembly rotates as a whole, the steel wire rope always keeps in contact with the inner side of the wear-resistant ring.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, by means of the movable disc, wire rope, spring telescopic rod, passive sleeve and sleeve groove, the device can clear the wet material blocked inside the friction reduction assembly in real time without the action of external force.

When the friction reduction assembly shakes as a whole, the wire rope fits the inner side of the wear-resistant ring and the wire rope is fixed, so that the wire rope can scrape the wet material blocked inside the wear-resistant ring and the double-column material column. This design can not only keep the sieve hole unobstructed, but also ensure the smooth passage of the wet material, thereby improving the screening efficiency;

[0022] 2. In the present invention, by means of the wear-resistant ring, the annular rotating sheet, the double-column material discharge column and the multi-annular rotating groove, the device can effectively control the friction force, prevent the sieve hole from increasing due to excessive friction, and affect the screening quality.

The smooth design helps to reduce friction, protect the sieve hole from wear, and ensure the uniformity and accuracy of the material during the screening process;

[0023] 3. In the present invention, by setting fixing screws, double-column unloading columns, fixed plates and movable plates, the device makes the maintenance and replacement process simpler and faster, reduces equipment downtime, improves production efficiency, and does not need to be replaced as a whole when a single friction reduction component is damaged, thereby reducing maintenance costs. This modular design not only improves the flexibility of the equipment, but also reduces the economic burden of maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] As a further implementation scheme of the present scheme, the double-column material discharge column 51 is shaped like two sections of cylinders with different diameters, the sieve hole 58 runs through the interior of the double-column material discharge column 51, the annular rotating piece 54 is shaped like a circular ring, and the annular rotating piece 54 is fixedly connected to the top and bottom ends of the wear-resistant ring 55, the outer side of the wear-resistant ring 55 rotates on the inner side of the multi-annular rotating groove 53 opened in the double-column material discharge column 51, the outer side of the second sealing ring 56 is fitted with the inner side of the multi-annular rotating groove 53 opened in the double-column material discharge column 51, and the top of the double-column material discharge column 51 is flush with the top of the fixed plate 46.

[0045] Working process: when clearing the blockage during wet material screening, the wet material is screened, the motor 27 is started, the motor 27 drives the spring telescopic rod 28 to rotate, the spring telescopic rod 28 drives the movable disc 26 to rotate, the movable disc 26 rotates with the center of the spring telescopic rod 28 as the axis, the movable disc 26 drives the column rod 29 to rotate, the outer side of the column rod 29 fits with the inner side of the sleeve groove 49 provided in the passive sleeve 48, when the column rod 29 rotates, the passive sleeve 48 is driven to rotate, the passive sleeve 48 drives the movable plate 45 to rotate, the movable plate 45 5 drives the fixed plate 46 fixed by bolts to rotate, and the fixed plate 46 drives the cover tube 43 and the expansion ring 41 to move inside the movable ring groove 25 opened in the cylinder shell 21. The lower end of the steel ball 42 fits with the inner side of the movable ring groove 25 opened in the cylinder shell 21. The steel ball 42 can reduce the friction between the expansion ring 41 and the cylinder shell 21. The cover tube 43 and the fixed plate 46 shake around the axis of the spring telescopic rod 28. The cover tube 43 squeezes the spring 6, and the spring 6 plays the effect of resetting the cover tube 43 and limiting the cover tube 43 at the same time, thereby achieving The fixed plate 46 and the wet material inside the cover tube 43 vibrate, and the first sealing ring 44 fixed on the top of the cover tube 43, the top of the first sealing ring 44 fits with the top of the movable ring groove 25 opened in the cylinder shell 21, and the first sealing ring 44 seals between the cylinder shell 21 and the cover tube 43, which can prevent the wet material from entering the movable ring groove 25.

When the wear-resistant ring 55 and the double-column material discharge column 51 are dredged, the wear-resistant ring 55 shakes in a circular trajectory, and the wire rope 24 passes through the double-column material discharge column 51 and the wear-resistant ring 55. When the friction reduction assembly 5 shakes as a whole, the wire rope 24 fits the inner side of the wear-resistant ring 55, and the wire rope 24 is fixed, so that the wire rope 24 can scrape the wet material blocked in the wear-resistant ring 55 and the double-column material discharge column 51, thereby keeping the inside of the wear-resistant ring 55 in a dredged state and ensuring the continuous operation of production;

[0046] When the friction reduction assembly 5 shakes as a whole, the steel wire rope 24 is prevented from causing the sieve hole to increase due to friction with the friction reduction assembly 5. When the above-mentioned friction reduction assembly 5 rotates as a whole, the steel wire rope 24 always keeps in contact with the inner side of the wear-resistant ring 55. When the steel wire rope 24 and the wear-resistant ring 55 rub against each other, the wear-resistant ring 55 will be driven to rotate under the action of friction force. The wear-resistant ring 55 is rotatably connected to the inner side of the multi-ring rotating groove 53 opened in the double-column unloading column 51 through the rotating piece 54, which plays a role in limiting the wear-resistant ring 55. The wear ring 55 is fitted with the inner side of the multi-ring rotating groove 53 provided in the double-column lower material column 51 through the second sealing ring 56, which can prevent the material from entering the multi-ring rotating groove 53. The material of the wear-resistant ring 55 is wear-resistant material, which increases the service life of the wear-resistant ring 55. At the same time, the inside of the wear-resistant ring 55 is a smooth structure, which minimizes the friction between the wire rope 24 and the wear-resistant ring 55. At this time, the wire rope 24 can be prevented from increasing the aperture inside the wear-resistant ring 55 due to friction, ensuring that the screening quality of the wet material is not affected;

[0047] When the friction reduction assembly 5 needs maintenance or replacement, the double-column material discharge column 51, the fixed plate 46 and the movable plate 45 can be separated by fixing the screws 57, and the double-column material discharge column 51 is pushed up from bottom to top. At this time, the double-column material discharge column 51 and the device inside the double-column material discharge column 51 can be separated from the fixed plate 46 and the movable plate 45. The upper end of the double-column material discharge column 51 has a larger diameter, which plays a role in limiting the position of the double-column material discharge column 51 when it is installed inside the fixed plate 46. The upper end of the double-column material discharge column 51 is flush with the upper end of the fixed plate 46 , to prevent materials from accumulating near the double-column material discharge column 51. At this time, the friction reduction component 5 can be maintained. When the friction reduction component 5 is replaced, the friction reduction component 5 is operated as a whole from the upper part of the fixed plate 46, and the double-column material discharge column 51 is inserted into the grooves inside the fixed plate 46 and the movable plate 45. The friction reduction component 5, the fixed plate 46 and the movable plate 45 are fixed by fixing screws 57. At this time, maintenance or replacement is completed to prevent the phenomenon that a single friction reduction component 5 is damaged and the entire component needs to be replaced, thereby reducing maintenance costs.
