Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to an air extraction cage for a papermaking machine. Background Art

[0002] The screen section of a rotary papermaking machine, often referred to as the cylinder, primarily consists of a cylinder, a trough, and a couch roll. The cylinder is the primary component on which the paper web is formed. It must filter water evenly and not cause excessive agitation in the trough during rotation. The cylinder should possess sufficient rigidity and precise dimensions. The couch roll and the cylinder are in contact with each other. Dewatering is achieved when the pulp passes through the former's pulp channel, enters the forming arc, and reaches the contact point between the couch roll and the cylinder. Cylinder cylinders are categorized by structure into standard, sheet, vacuum, and vacuum. Standard cylinders have limited filtration area and speed, and therefore cannot significantly improve paper quality.

[0003] After searching, the publication number CN203977225U relates to a technical field of papermaking equipment, and is a vacuum cage for a papermaking machine, comprising a cast iron rotating shaft, an inner mesh and an outer mesh, horizontal bars, stainless steel sheets, a cover plate, a spoke support rib device, a center wheel rim and a suction port; the center wheel rim is engraved with grooves around the periphery; the horizontal bars are embedded in the grooves, and there are serrated small grooves on the horizontal bars; the serrated small grooves are embedded with stainless steel sheets to form a cage frame; the cage frame is covered with an inner mesh and an outer mesh. Cover plates are provided at both axial ends of the cage, and a suction port is provided on the cover plate, and the suction port is connected to a water pump through a pipe. The suction port, pipe and water pump together constitute a pumping system, which is used to suck the air in the cage to reduce the air pressure in the cage and absorb excess white water in the cage, thereby enhancing the dehydration rate of the pulp slurry and improving papermaking efficiency.

[0004] The above patent mentioned that "the mesh cage is provided with cover plates at both axial ends, and the cover plates are provided with suction ports, which are connected to the water pump through pipes. The suction ports, pipes and water pumps together constitute a pumping system, which is used to suck the air in the mesh cage to reduce the air pressure in the cage and absorb excess white water in the cage, thereby enhancing the dehydration rate of pulp slurry and improving papermaking efficiency." However, in actual use, after the excess white water is pumped out of the cage, it is directly discharged, which will cause a waste of water resources and cannot be collected and recycled. Therefore, in response to the above problems, an air suction mesh cage for a papermaking machine is proposed. Utility Model Content

[0047] Working principle: When the net drum 4 is pumping air and water from the pulp, it only needs to start the water pump 8, so that the water pump 8 generates suction to discharge the water and gas inside the net drum 4 through the connecting pipe 2 7 and the connecting pipe 1 6, and then the pumped water and gas are transported into the water storage cylinder 10 through the water pipe 9, so that the impurities in the water are filtered through the filter plate 12 inside the water storage cylinder 10, and then the odor in the gas is adsorbed by the activated carbon plate 13, and then the water gas after filtration and adsorption is discharged through the valve, and then the filter plate 12 is quickly opened when it is needed. When replacing, it is only necessary to toggle the limiting ring 17 to the right so that the limiting ring 17 slides into the inside of the limiting groove 16, then hold the handle to pull the pulling ring 11, and then pull out the filter plate 12 inside the pulling ring 11, and then replace or clean the filter plate 12, and then put the pulling ring 11 and the filter plate 12 back into the inside of the water storage cylinder 10, and then loosen the limiting ring 17, so that the connecting rod 18 cooperates with the limiting ring 17 of the spring 19 to push, so that the limiting ring 17 is reset and the outside of the pulling ring 11 is restricted again;

[0048] Then when the mesh cylinder 4 vacuums the pulp, the pulp will penetrate into the interior of the mesh cylinder 4, and then the mesh cylinder 4 drives the rotating shaft 2 to rotate through an external driving source, and then when the mesh cylinder 4 rotates, the scraper 23 will swing outside the connecting shaft 22 due to inertia problems, and then the scraper 23 will scrape the inner wall of the mesh cylinder 4 back and forth, and then when the scraper 23 swings back and forth and scrapes, it will hit the cylindrical sleeve 26 back and forth. During the collision, the cylindrical sleeve 26 will squeeze the spring 25 and slide inside the sleeve 24. Then when the scraper 23 swings back and forth inside the mesh cylinder 4, it will hit the cylindrical sleeves 26 on both sides back and forth while being elastically buffered by the spring 25, thereby reducing the vibration of the scraper 23 inside the mesh cylinder 4.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
