[0026] Embodiment one

[0027] Please refer to Figures 1-5 The utility model discloses a kind of metal surface treatment waste water filtering devices of convenient cleaning shown in the drawing, including filter box 4 and communication box 3;

[0028] The communication box 3 is arranged at the top of one side of the filter box 4 and communicates with the liquid inlet of the filter box 4, and one side of the communication box 3 is connected with a liquid inlet pipeline;

[0029] One end of the communication box 3 communicates with the collection bin 13, and the inner cavity bottom of the communication box 3 is provided with an arc-shaped groove 8, and the arc-shaped groove 8 is connected with a plurality of magnet plates 14, and the inside of the communication box 3 and away from the collection bin 13 is provided with a pushing structure.

[0030] In the use of the convenient-to-clean wastewater filter device for metal surface treatment, the wastewater is first introduced into the communication box 3 through the liquid inlet pipeline. The communication box 3 is arranged at the top of one side of the filter box 4 and communicates with the liquid inlet of the filter box 4, which ensures that the wastewater can smoothly and orderly enter the filter system. With the inflow of wastewater, the iron slag and other magnetic impurities in the wastewater are firmly adsorbed by the plurality of magnet plates 14 embedded in the arc-shaped groove 8 at the bottom of the communication box 3 when flowing through the arc-shaped groove 8. These magnet plates 14 effectively separate the magnetic impurities such as iron slag in the wastewater by magnetic force, avoiding the blockage of the filter components after they enter the filter box 4.

[0031] At the same time, the pushing structure arranged at the side of the communication box 3 away from the collection bin 13 starts to work. The iron slag and other impurities adsorbed on the magnet plates 14 are moved towards the collection bin 13. When these impurities accumulate to a certain extent, they will naturally fall into the collection bin 13 which communicates with one end of the communication box 3.

[0032] Example two

[0033] Please refer to Figures 1-5 The wastewater filter device for metal surface treatment of the embodiment is provided with a communication port 6 on one side of the communication box 3 for communication with the liquid inlet of the filter box 4, and a filter plate 5 is bolted and fixedly connected in the communication port 6. Specifically, the wastewater will be preliminarily filtered by the filter plate 5 before entering the communication box 3 through the communication port 6 on one side of the communication box 3 and the filter plate 5 bolted and fixedly connected in the communication port 6. The filter plate 5 can intercept part of the large-particle impurities in the wastewater, reduce the filtering burden of the subsequent magnet plates 14 and filter box 4, facilitate disassembly and cleaning, and achieve the effects of improving the overall filtering efficiency and prolonging the service life of the equipment.

[0034] The liquid inlet pipeline comprises a distribution pipe 2 and a plurality of liquid inlet pipes 1, one end of the liquid inlet pipe 1 is communicated with the inside of the communication box 3, the other end is communicated with the inside of the distribution pipe 2, and one side of the distribution pipe 2 is communicated with a connecting pipe for sewage entering. Specifically, through the setting of the distribution pipe 2 and the plurality of liquid inlet pipes 1 contained in the liquid inlet pipeline, the wastewater can enter the communication box 3 through the plurality of liquid inlet pipes 1 at the same time, thereby improving the wastewater treatment efficiency. At the same time, the design of the distribution pipe 2 facilitates the uniform distribution of wastewater to each liquid inlet pipe 1, ensuring the uniformity and stability of wastewater treatment, thereby improving the wastewater treatment efficiency and stability.

[0035] Embodiment three

[0036] Please refer to Figures 1-5 As shown in the drawings, the wastewater filtering device for metal surface treatment convenient to clean of the embodiment is movably provided with a collection box 10 in the inside of the collection bin 13, a plurality of through holes 12 are formed in the bottom of the inner cavity of the collection box 10, and specifically, when the pushing structure pushes the iron slag and other impurities adsorbed on the magnet plate 14 to the collection bin 13, the impurities will fall into the collection box 10 through the setting of the collection box 10 movably provided in the inside of the collection bin 13 and the through holes 12 formed in the bottom of the inner cavity of the collection box 10. The movable setting of the collection box 10 facilitates the subsequent removal and cleaning of the collection box 10, and the through holes 12 ensure the smooth flow of wastewater while preventing the backflow of impurities into the communication box 3 or the filtering box 4, thereby achieving the effect of efficiently collecting and conveniently cleaning the iron slag and other impurities.

[0037] The top of the collection box 10 is connected with a connecting rod 11, an opening corresponding to the collection bin 13 is formed in the top of the communication box 3, the inside of the opening is connected with a cover 7, and the bottom of the cover 7 is connected with the top of the connecting rod 11 through a connecting rope. Specifically, when it is necessary to clean the impurities in the collection box 10, the cover 7 is only needed to be opened, and the connecting rod 11 and the collection box 10 are pulled out through the connecting rope, so that the cleaning can be conveniently performed. This design not only simplifies the cleaning process, but also avoids the direct contact of the operator with the impurities, thereby improving the cleaning convenience and safety.

[0038] The pushing structure comprises a push plate 15 matched with the shape of the arc-shaped groove 8 and a pushing cylinder 9 installed at one end of the communication box 3, and the output end of the pushing cylinder 9 is slidably connected with the push plate 15 through the side wall of the communication box 3. Specifically, through the setting of the push plate 15 and the pushing cylinder 9 contained in the pushing structure, the pushing cylinder 9 can drive the push plate 15 to slide in the arc-shaped groove 8, so as to push the iron slag and other impurities adsorbed on the magnet plate 14 to the collection bin 13. This design not only realizes the automatic cleaning of the impurities, but also realizes the precise control of the impurity cleaning process by controlling the working frequency and force of the pushing cylinder 9, thereby improving the cleaning efficiency and the degree of automation.

[0039] The scheme has the following working process:

[0040] The wastewater is first introduced into the system through the liquid inlet pipeline, which includes a distribution pipe 2 and a plurality of liquid inlet pipes 1. The wastewater enters the distribution pipe 2 from the connecting pipe, and is then uniformly distributed to each liquid inlet pipe 1 and simultaneously enters the communication box 3. This design: the cooperation of the distribution pipe 2 and the liquid inlet pipe 1 improves the treatment efficiency of the wastewater, ensures the uniformity and stability of the wastewater treatment, and helps to improve the overall treatment effect.

[0041] The communication box 3 is arranged at the top of one side of the filter box 4 and is tightly connected with the liquid inlet of the filter box 4 through the communication port 6. Before the wastewater enters the communication box 3, it will first pass through the filter plate 5 fixedly connected inside the communication port 6 for preliminary filtration. The filter plate 5 intercepts part of the large particle impurities in the wastewater, reducing the filtration burden of the subsequent filter box 4. The communication port 6 and the filter plate 5 not only improve the overall filtration efficiency, but also prolong the service life of the equipment, and are convenient to disassemble and clean.

[0042] As the wastewater flows in, the iron slag and other magnetic impurities in the wastewater are firmly adsorbed by the plurality of magnet plates 14 embedded in the arc-shaped groove 8 when flowing through the arc-shaped groove 8 opened at the bottom of the communication box 3. The magnet plates 14 effectively separate the magnetic impurities such as iron slag in the wastewater by magnetic force, avoiding their clogging of the filter components after entering the filter box 4. This step is a key link in the wastewater treatment, ensuring the normal operation and filtration effect of the filter box 4.

[0043] At the same time, the push structure arranged at the side of the communication box 3 away from the collection bin 13 starts to play a role. The push structure includes a push plate 15 matched with the shape of the arc-shaped groove 8 and a push cylinder 9 installed at one end of the communication box 3. The push cylinder 9 drives the push plate 15 to slide in the arc-shaped groove 8, pushing the impurities such as iron slag adsorbed on the magnet plates 14 to the collection bin 13. The push plate 15 and the push cylinder 9 not only realize the automatic cleaning of the impurities, but also realize the control of the impurity cleaning process by controlling the working frequency and force of the push cylinder 9, improving the cleaning efficiency and automation degree.

[0044] The impurities fall into the collecting bin 13 communicated with one end of the communicating box 3. The inside of the collecting bin 13 is movably provided with the collecting box 10, and a plurality of through holes 12 are formed in the bottom of the inner cavity of the collecting box 10. The through holes 12 ensure that the waste water can flow smoothly, and prevent the impurities from flowing back to the communicating box 3 or the filtering box 4. The movable arrangement of the collecting box 10 facilitates the subsequent taking out and cleaning. In addition, the top of the collecting box 10 is connected with a connecting rod 11, and the top side of the communicating box 3 is provided with an opening corresponding to the collecting bin 13, and the inside of the opening is connected with a cover 7, and the bottom of the cover 7 is connected with the top of the connecting rod 11 through a connecting rope. The collecting box 10, the through holes 12, the connecting rod 11 and the cover 7 not only simplify the cleaning process, but also avoid the direct contact of the operator with the impurities, and improve the convenience and safety of the cleaning.
