[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a coal-containing wastewater filtration device, comprising a filter tank 1, two mounting plates 2 fixedly connected to the inner side wall of the filter tank 1, and a vibration mechanism provided at the top of the two mounting plates 2.

[0034] The vibration mechanism includes two vibration motors 3, both of which are fixedly connected to the top of the mounting plate 2. The output ends of both vibration motors 3 are fixedly connected to couplings 4. The ends of both couplings 4 furthest from the vibration motors 3 are fixedly connected to rotating shafts 5. Eccentric wheels 6 are fixedly connected to the middle of both rotating shafts 5. Housings 7 are provided on the outer sides of both eccentric wheels 6. Guide grooves 8 are provided at the top of both housings 7. Positioning holes 9 are provided on the inner bottom walls of both guide grooves 8. Buffer pads 10 are provided in the middle of both guide grooves 8. Vibration plates 11 are provided at the top of both buffer pads 10. Positioning columns 12 are fixedly connected to the bottom ends of both vibration plates 11. A flow-dividing assembly is provided at the top of the inner wall of the filter tank 1. Two grooves 17 are provided on the inner walls of both housings 7. Bearings 18 are provided on the left and right sides of both eccentric wheels 6. Multiple positioning columns 12 are slidably connected to the inner walls of the positioning holes 9, and multiple bearings 18 are provided on the inner walls of the grooves 17.

[0035] Specifically, by designing two grooves 17 on the inner wall of the housing 7 and embedding the bearing 18 into the inner wall of the grooves 17, the friction between the rotating shaft 5 and the housing 7 is reduced, thereby extending the service life of the housing 7.

[0036] Reference Figure 1 and Figure 4 The diversion assembly includes a crossbeam 13, which is fixedly connected to the top of the inner wall of the filter tank 1. A rotating seat 14 is fixedly connected to the middle of the crossbeam 13. A diversion fan blade 15 is fixedly connected to the outer side of the middle of the rotating seat 14. A diversion hood 16 is threadedly connected to the top of the rotating seat 14.

[0037] Specifically, the impact of the water flow on the diversion fan blades 15 effectively mitigates the direct impact of the water flow on the filter media layer, thereby improving the filtration efficiency.

[0038] Reference Figure 1 The inner wall of the filter tank 1 has multiple evenly distributed plastic meshes 19. The top of the top plastic mesh 19 has a coarse filter layer 20, the top of the middle plastic mesh 19 has a fine filter layer 21, and the top of the bottom plastic mesh 19 has an activated carbon layer 22. The top of the filter tank 1 is connected to an inlet pipe 23, and the right side of the filter tank 1 is connected to an outlet pipe 24. The left end of the filter tank 1 is fixedly connected to a backwash pump 25, and the left end of the backwash pump 25 is rotatably connected to a backwash control valve 26. The top of the backwash pump 25 is connected to a backwash water pipe 27, and the bottom end of the filter tank 1 is fixedly connected to a wastewater drain valve 28.

[0039] Specifically: By setting plastic mesh 19 between different filter media layers, filter media mixing can be prevented while allowing water to flow smoothly. By setting backwashing structure, when backwashing is required, backwashing water pump 25 can be started to inject clean water from the bottom of filter tank 1 through backwashing water pipe 27 to clean the filter media layer, flush out accumulated pollutants from the filter media layer, and discharge the wastewater from filter tank 1 through wastewater drain valve 28.

[0040] It should be noted that (vibration motor 3, coupling 4, rotary seat 14, backwash pump 25, backwash control valve 26, wastewater drain valve 28) are all well-known or known to those skilled in the art, and therefore will not be described here.

[0041] Working principle: Coal-containing wastewater enters the filter tank 1 through the inlet pipe 23, passing sequentially through the coarse filter layer 20, the fine filter layer 21, and the activated carbon layer 22. Pollutants are intercepted on the filter layers, and the filtered clean water is discharged through the outlet pipe 24. Simultaneously, by setting plastic mesh 19 between different filter layers, the filter media mixing is prevented while allowing smooth water flow. A crossbeam 13 is installed on the inner wall of the filter tank 1, and a rotating seat 14 is fixed on it. A diversion fan blade 15 is located on the outer side of the center of the rotating seat 14, and its top is connected to the diversion hood 16 by threads. This design utilizes the impact of the water flow on the diversion fan blade 15 to effectively mitigate the direct impact of the water flow on the filter layers, thereby improving filtration efficiency.

[0042] Meanwhile, an eccentric wheel 6 is arranged in the inner cavity of the housing 7, and a guide groove 8 for the movement of the vibrating plate 11 is provided on the top of the housing 7. The guide groove 8 is provided with a positioning hole 9, and the positioning post 12 at the bottom of the vibrating plate 11 can slide in the positioning hole 9. The vibration motor 3 drives the rotating shaft 5 to rotate the eccentric wheel 6, and the eccentric wheel 6 applies a periodic squeezing action to the vibrating plate 11, thereby causing the vibrating plate 11 to generate periodic vibration on the plastic mesh 19 supporting the filter material layer. This vibration helps to loosen the filter material layer, prevent filter layer caking, and ensure unobstructed filtration channels.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
