Description

Technical Field

[0001] The utility model relates to the technical field of papermaking water recovery, in particular to a papermaking water recovery device. Background Art

[0002] A large amount of wastewater is discharged during the papermaking industry, which contains a large amount of suspended fiber, lignin, organic matter and other pollutants. Therefore, the wastewater needs to be purified before it can be recycled, and the solid matter in the wastewater needs to be filtered out before purification.

[0003] At present, in the process of recycling papermaking wastewater, it is necessary to filter out solids in the wastewater through a filter. However, the filter is easily blocked by solids such as suspended fibers in the wastewater during use. Therefore, we propose a papermaking water recovery device. Utility Model Content

[0004] The utility model aims to provide a papermaking water recovery device, which has the advantages of being able to remove and drain suspended fibers and other solids trapped on a filter screen during the papermaking wastewater recovery process, thereby preventing the filter screen from being blocked and ensuring the filtering efficiency of the papermaking wastewater. It solves the problem that in the current process of papermaking wastewater recovery, the solids in the wastewater need to be filtered out through a filter screen, but the filter screen is easily blocked by suspended fibers and other solids in the wastewater during use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a papermaking water recovery device, comprising a filter box, a horizontal plate is fixedly installed on the upper surface of the filter box, a conical filter disc is rotatably installed on the lower surface of the horizontal plate through a rotating shaft, a rotating motor is fixedly installed on the upper surface of the horizontal plate, a water inlet pipe is fixedly installed on the upper surface of the horizontal plate near the rear surface, a water outlet pipe is fixedly connected to the outer surface of the filter box near the lower surface, an arc scraper is fixedly installed on one side of the interior of the filter box at a position above the conical filter disc, a slag discharge port is provided on the outer surface of the filter box near the arc scraper, and the slag discharge port is located above the conical filter disc.

[0006] Preferably, the end of the output shaft of the rotating motor and the end of the rotating shaft are fixedly connected.

[0007] Preferably, four legs are fixedly connected at equal intervals in a circular array near the edge of the lower surface of the filter box.

[0008] Preferably, a trigger switch is fixedly installed on the inner wall of the filter box near the slag discharge port, and the trigger switch is located above the conical filter disc.

[0009] Preferably, an extrusion cylinder is fixedly installed on one side of the outer surface of the filter box close to the slag discharge port, and the extrusion cylinder and the filter box are connected through the slag discharge port. An extrusion screw is rotatably installed inside the extrusion cylinder, and a slag discharge valve is fixedly connected to the side of the lower surface of the extrusion cylinder facing away from the filter box.

[0010] Preferably, an extrusion motor is fixedly mounted on the outside of the extrusion cylinder, and the end of the extrusion motor output shaft is fixedly connected to the end of the extrusion screw.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model achieves the effect of facilitating the removal and discharge of solids such as suspended fibers trapped on the filter screen during the papermaking wastewater recovery process by arranging a filter box, an arc-shaped scraper, a conical filter screen, a rotating motor and a slag discharge port, thereby preventing the filter screen from being blocked and ensuring the filtration efficiency of the papermaking wastewater. The papermaking wastewater enters the filter box from the water inlet pipe and falls onto the conical filter screen. The solids in the wastewater are filtered out and trapped by the conical filter screen. The rotating motor drives the conical filter screen to rotate, and the arc-shaped scraper scrapes off the solids trapped on the conical filter screen and discharges them from the slag discharge port.

[0013] 2. The utility model achieves the effect of automatically controlling the cleaning of the conical filter disc by setting a trigger switch. Papermaking wastewater enters the filter box from the water inlet pipe and falls onto the conical filter disc. As the waste residue on the conical filter disc near the bottom of the water inlet pipe increases, it will hinder the papermaking wastewater from passing through the conical filter disc. Therefore, the wastewater will gradually flow along the conical filter disc and approach the trigger switch. When the trigger switch contacts the papermaking wastewater, the rotating motor is triggered to work, and the waste residue on the conical filter is scraped off by the arc scraper. Therefore, the rotating motor does not need to run continuously, which reduces energy consumption and also reduces the wear of the arc scraper and the conical filter disc.

[0014] 3. The utility model achieves the effect of squeezing out water in the waste residue and reducing the waste of water resources by arranging an extrusion barrel and an extrusion screw, and also facilitates the transportation of the waste residue. After the waste residue filtered out by the conical filter plate enters the extrusion barrel, the extrusion motor drives the extrusion screw to rotate and squeeze the waste residue, squeezing out the water in the waste residue and returning it to the inside of the filter box, and the waste residue with the water squeezed out is discharged through the slag discharge valve.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0023] A trigger switch 15 is fixedly installed on the inner wall of the filter box 1 near the slag discharge port 11, and the trigger switch 15 is located above the conical filter disc 13. Papermaking wastewater enters the filter box 1 from the water inlet pipe 8 and falls onto the conical filter disc 13. As the waste residue on the conical filter disc 13 near the bottom of the water inlet pipe 8 increases, it will hinder the papermaking wastewater from passing through the conical filter disc 13. Therefore, the wastewater will gradually flow along the conical filter disc 13 and approach the trigger switch 15. When the trigger switch 15 contacts the papermaking wastewater, the rotating motor 9 is triggered to work, and the waste residue on the conical filter disc 13 is scraped off by the arc scraper 6. Therefore, the rotating motor 9 does not need to run continuously, which reduces energy consumption and also reduces the wear of the arc scraper 6 and the conical filter disc 13.

[0024] When the utility model is in use, papermaking wastewater enters the filter box 1 from the water inlet pipe 8 and falls onto the conical filter plate 13, and solids in the wastewater are filtered out and retained by the conical filter plate 13. The rotating motor 9 drives the conical filter plate 13 to rotate, and the arc scraper 6 scrapes off the solids retained on the conical filter plate 13 and discharges them from the slag discharge port 11, thereby preventing the occurrence of filter blockage and ensuring the filtration efficiency of the papermaking wastewater.

[0027] In this embodiment, after the waste residue filtered out by the conical filter plate 13 enters the extrusion cylinder 5, the extrusion motor 4 drives the extrusion screw 10 to rotate and extrude the waste residue, thereby squeezing out the water in the waste residue and returning it to the filter box 1. The waste residue from which the water has been squeezed out is discharged through the slag discharge valve 3, thereby reducing the waste of water resources and facilitating the transportation of the waste residue.
