Description

Technical Field

[0001] The utility model relates to the technical field of wastewater purification, in particular to an industrial wastewater filtering and purifying device for cleaning metal parts. Background Art

[0002] Industrial wastewater used for metal parts cleaning is generated during the manufacturing, processing, surface treatment and subsequent maintenance of metal parts. These wastewaters usually contain a variety of pollutants such as chemicals, grease and heavy metal ions. If they are discharged directly without treatment, they will have a serious impact on the environment. Treating this type of industrial wastewater through filtering and purification equipment can effectively avoid the pollution of water and soil by these pollutants.

[0003] The existing Chinese patent with announcement number CN209923075U discloses an industrial wastewater filtering and purification device, including a filter seat and a plurality of neatly arranged flat filter containers, the filter seat including a base, an inlet end and an outlet end, the outer side of the inlet end is integrally provided with a flange connected to the industrial wastewater pipe, the inner side is provided with an upper diversion port nested and sealed with the filter container, the outer side of the outlet end is also integrally provided with a flange connected to the outlet pipe, the inner side is provided with a lower diversion port nested and sealed with the filter container, the lower diversion ports are neatly arranged, corresponding to a plurality of neatly arranged flat filter containers in sequence, the filter container includes a filter assembly, an inlet and an outlet, the filter assembly includes a filter screen for circuitously blocking and filtering industrial wastewater, and the filter screen has a chemical purification treatment agent.

[0004] Although the filter container of the above scheme is replaceable and maintainable, and is practical and convenient, its filtering effect is not significant for the removal of heavy metal ions when treating industrial wastewater from metal parts cleaning. Metal parts will inevitably come into contact with various heavy metal ions during manufacturing and use. These ions exist stably in wastewater and are difficult to be effectively removed by conventional filtering methods. In addition, metal parts cleaning wastewater often contains large particles of suspended matter, which cannot be blocked on the filter net of the filtering and purification device and are difficult to clean. Therefore, it does not meet the existing needs. In this regard, we propose an industrial wastewater filtering and purification device for metal parts cleaning. Utility Model Content

[0005] The purpose of the utility model is to provide an industrial wastewater filtering and purification device for cleaning metal parts, so as to solve the problems that the filtering and purification device proposed in the above background technology has no significant effect on heavy metal ion treatment and large particles of suspended matter are blocked on the filter net, resulting in poor subsequent purification treatment effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an industrial wastewater filtering and purification device for cleaning metal parts, comprising a filter box, an upper end of the filter box is provided with a water inlet pipe, a lower side of one side of the filter box is provided with a water outlet pipe, and one end of the water inlet pipe and the water outlet pipe extends to the interior of the filter box;

[0008] It also includes an ion exchange resin column, which is arranged on the lower side of the filter box, and a plurality of ion exchange resin columns are arranged in a rectangular array, and two activated carbon purification plates are arranged on the upper side of the filter box;

[0009] It also includes a transmission cavity, which is opened on the lower side of the filter box. Stirring rods are arranged on both sides of the transmission cavity. One end of the stirring rods extends to the outside of the transmission cavity, and the stirring rods are rotatably matched with the transmission cavity.

[0010] Preferably, a motor is provided at the lower end of the transmission chamber, and an output end of the motor is transmission-connected to one of the stirring rods via a coupling.

[0015] Preferably, the outer wall of the stirring rod at one end outside the transmission cavity is welded with three groups of stirring blades distributed evenly, and each group of stirring blades is welded with four stirring blades distributed evenly in a ring shape.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model provides a filter plate inside the water inlet pipe, and filter screens are provided on both sides of the filter plate, so that large suspended particles can be filtered. When industrial wastewater passes through, the flow of water will drive the fan blades to rotate, thereby driving the rotating shaft to make the L-shaped rod rotate synchronously, and the L-shaped rod will drive the cleaning brush to clean the upper and lower end surfaces of the filter screen, which can sweep away the blocked large suspended particles, thereby avoiding clogging of the filter screen, ensuring the filtering effect of the filter screen, avoiding affecting the subsequent purification treatment, and eliminating the need for manual cleaning of the filter screen, which is easy to use.

[0018] The utility model has a plurality of ion exchange resin columns distributed in a rectangular array on the lower side of the interior of the filter box. The ion exchange resin columns have a high degree of selectivity and adsorption capacity and can exchange with heavy metal ions in industrial waste water after metal parts are cleaned. When the industrial waste water passes through the ion exchange resin columns, the heavy metal ions will undergo ion exchange reactions with the active groups on the resin, thereby being firmly adsorbed on the resin, so that the heavy metal ions in the industrial waste water can be effectively removed, thereby achieving the purpose of purifying water quality.

[0019] The utility model opens a transmission cavity at the lower end of the filter box. After starting the motor in the transmission cavity, one of the stirring rods can be rotated, and the other stirring rod can be synchronously rotated under the drive of the transmission belt. The stirring rods can drive the stirring blades to rotate synchronously. The rotating stirring blades can promote the flow of industrial wastewater and make the industrial wastewater pass through the ion exchange resin column more evenly, which helps to increase the contact area between the ion exchange resin column and the industrial wastewater and improve the efficiency of ion exchange.

[0031] During use, when the industrial waste water after cleaning the metal parts is passed into the water inlet pipe 2, the water flow will drive the fan blades 9 to rotate. At this time, the water flow drives the fan blades 9 to rotate synchronously with the rotating shaft 8. The bearing 7 ensures the smooth rotation of the rotating shaft 8, so that the cleaning brush 11 can be driven by the L-shaped rod 10 to clean the filter screen 6, which can avoid clogging the filter screen 6, ensure the filtering effect of the filter screen, avoid affecting the subsequent purification treatment, and do not need to manually clean the filter screen 6, which is easy to use.

After the industrial wastewater enters the filter box 1, it will be adsorbed and purified by the activated carbon purification plate 12. After that, it will enter the lower side of the filter box 1 and contact the ion exchange resin column 13. The heavy metal ions will undergo ion exchange reaction with the active groups on the resin, thereby being firmly adsorbed on the resin, thereby achieving effective removal of the heavy metal ions. At this time, the motor 15 can be started, and the motor 15 will drive one of the stirring rods 16 to rotate. Under the transmission of the transmission belt 18, the other stirring rod 16 can be rotated, and the two stirring rods 16 can rotate synchronously. The rotation of the stirring rod 16 will drive the stirring blades 17 to rotate synchronously, thereby promoting the flow of industrial wastewater, which helps to increase the contact area between the ion exchange resin column 13 and the industrial wastewater, improve the efficiency of ion exchange, and increase the purification effect. The staff can observe the filtration through the observation window 3, which is practical.
