Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to an automatic filtering device for papermaking waste residue. Background Art

[0002] The automatic papermaking waste residue filtering device is a device used to treat waste residue and impurities generated in the papermaking production process. Its main function is to effectively remove waste residue in an automated way to ensure pulp quality and production efficiency.

[0003] The patent with patent announcement number CN216837357U relates to a wastewater filtering and screening equipment for paper mills, and relates to the field of wastewater treatment technology. The patent includes a box body, a fixing frame and a base. The side end of the fixing frame is fixedly connected to the side wall of the box body, and the base is fixedly connected to the bottom end of the box body. A water inlet is opened at the top of the box body, and a drain outlet is opened at the bottom right end of the box body. The side end of the drain outlet is fixedly connected to a water collection chamber, and the side end of the water collection chamber is fixedly connected to a filter tank. Since the existing wastewater filtering device for paper mills consumes too much energy during use, it is inconvenient to discharge the waste residue at the screening site, and the wastewater filtering efficiency is not good. The transmission wheel at the side end of the stirring rod is engaged with the transmission wheel at the bottom end of the transmission shaft, so that the transmission shaft drives the stirring rod to rotate in the filter tank to stir the sewage, so that the sewage is more efficient during filtration, and the sewage flushes the water guide turntable to drive the stirring rod in the filter tank to rotate, so that it saves more energy consumption, saves time and labor.

[0004] In the above patent, the transmission shaft drives the stirring rod to rotate in the filter tank to stir the sewage, making the sewage more efficient during filtration. The sewage flushes the water guide turntable to drive the stirring rod in the filter tank to rotate, making it more energy-saving, time-saving and labor-saving. However, in the process of sewage treatment, the waste residue on the surface of the filter plate will gradually increase, and the subsequent sewage treatment effect will gradually decrease, and the subsequent maintenance cost will increase. For this reason, an automatic filtering device for papermaking waste residue with better filtering effect is designed. Summary of the invention

At the same time, under the action of the connecting rod, rotating rod and telescopic elastic rod, the rotating rod intermittently scrapes the top of the filter plate, further avoiding that part of the waste residue remains on the top of the filter plate, thereby causing more and more waste residue to accumulate in the subsequent sewage treatment process, resulting in a gradual decrease in the filtering effect of the filter plate on wastewater, thereby reducing the subsequent maintenance cost.

[0015] (2) The automatic filtering device for papermaking waste residues operates in coordination among a residue discharge pipe, a residue collecting frame, an L-shaped rod, a pressure plate, a connecting plate and a partition. The partition moves downward to release the seal on the discharge port on the surface of the residue collecting frame. After the seal on the discharge port is released, the waste residue collected in the residue collecting frame will be discharged to the outside through the residue discharge pipe, thereby realizing the intermittent regular discharge of waste residue in papermaking wastewater. It can effectively solve the problem of blockage caused by the accumulation of waste residue when the filter plate treats wastewater for a long time, and at the same time avoid excessive wastewater from being discharged through the residue discharge pipe, effectively reducing the subsequent treatment cost.

[0016] (3) The automatic filtering device for papermaking waste residue drives the guide plate to swing and changes the discharge angle of sewage through the coordinated operation of the guide frame, receiving rod, guide plate, connecting rod, conduction rod, pushing rod and support block, thereby preventing sewage from being discharged vertically directly onto the top of the filter plate, reducing the impact force on the filter plate, maintaining the stability of the filter plate during the up and down movement, and extending the service life of the equipment. At the same time, by changing the discharge angle of sewage, it can reduce the situation where solid waste residue is directly concentrated on the top of the filter plate, reduce the risk of filter plate clogging, and further enable the filter plate to maintain a good filtration flow and efficiency.
