Technical Field

[0001] The utility model relates to the technical field of filter screen cleaning, in particular to a filter screen cleaning mechanism for a water conservancy project gate. Background Art

[0002] The gate filter screen is an important component of water treatment equipment. Its main function is to filter out impurities in the water flow when the upstream water area flows through the open gate to the downstream water area, so as to protect the gate and other downstream equipment from damage, and at the same time improve water quality. The filter screen is usually made of metal mesh, plastic mesh or other corrosion-resistant materials, and has sufficient strength and durability to withstand the impact of water flow and the abrasion of impurities. Its design usually takes into account the filtration efficiency, water flow resistance, and the need for easy cleaning and maintenance.

[0003] The existing gate filter screen cannot automatically clean the sundries intercepted by itself, so a large amount of sundries accumulate at the gate filter screen and need to be manually cleaned many times, which is time-consuming and laborious, and also affects the normal operation of the gate, water quality safety, and the service life of the gate filter screen.

[0039] The present utility model will be further described in combination with the following embodiments.

[0040] Embodiment 1.

[0041] As Figures 1 - 3 shown, a filter screen cleaning mechanism for a water conservancy project gate includes a gate body 1, a filter screen assembly 2 is installed on the gate body 1, and the bottom pipeline of the filter screen assembly 2 is connected to a cleaning assembly 3.

[0042] As Figures 1 - 3As shown in the figure, the filter screen assembly 2 includes a square frame plate 4, which is vertically installed on the gate body 1. Inside the square frame plate 4, a hollowed-out support plate A 5 and a hollowed-out support plate B 6 are vertically installed. Both the hollowed-out support plate A 5 and the hollowed-out support plate B 6 are fixedly composed of a plurality of elastic rods 20 that intersect horizontally and vertically with each other, playing a role of elastic support and being more durable than ordinary filter screen support structures.

[0043] The hollowed-out support plate A 5 is close to the upstream water area, and the hollowed-out support plate B 6 is close to the downstream water area. The water flow at the gate flows through the hollowed-out support plate A 5 and then through the hollowed-out support plate B 6.

[0044] As Figures 1 - 3 shown in the figure, a diversion filter screen 7 is fixedly installed between the hollowed-out support plate A 5 and the hollowed-out support plate B 6. The diversion filter screen 7 includes a filter screen window A 8 and a filter screen window B 9. The aperture of the water leakage holes of the filter screen window A 8 is larger than that of the filter screen window B 9.

[0045] The water flow at the gate flows into the interior of the diversion filter screen 7 through the hollowed-out support plate A 5. The sundries carried in the water flow flow into the filter screen window A 8 with a larger aperture of the water leakage holes and are blocked on the filter screen window B 9 with a smaller aperture of the water leakage holes.

[0046] As Figures 1 - 3 shown in the figure, the filter screen window A 8 is fixedly installed on the hollowed-out support plate A 5, and the filter screen window B 9 is fixedly installed on the hollowed-out support plate B 6. A plurality of stepped plates 10 are vertically installed between the hollowed-out support plate A 5 and the hollowed-out support plate B 6. The high-end of the stepped plate 10 is installed on the hollowed-out support plate A 5, and the low-end of the stepped plate 10 is installed on the hollowed-out support plate B 6. A water passing port 16 is opened near the hollowed-out support plate B 6 of the stepped plate 10. The waterways between the plurality of stepped plates 10 are connected. A shredder 11 is installed on the hollowed-out support plate A 5.

[0047] By connecting the waterways between the hollowed-out support plate A 5 and the hollowed-out support plate B 6 through a plurality of stepped plates 10, the water flow can be shunted horizontally when passing through the stepped plates 10. The water flow flows in the stepped sandwich layers formed by the plurality of stepped plates 10, which can weaken the impact force of the water flow on the filter screen window B 9. At the same time, the stepped plates 10 are stepped in the vertical direction to guide the water flow with sundries to flow layer by layer on the stepped plates 10 through the water passing port 16. Finally, the sundries will be pressed to the bottom of the filter screen assembly 2 under the continuous water pressure.

[0048] As Figures 1 - 3As shown in the figure, the shredder 11 includes a plurality of support rods 12. The support rods 12 are horizontally installed on the side of the hollow support plate A close to the upstream water area. The plurality of support rods 12 are equidistantly installed on the hollow support plate A 5. A plurality of blades 13 are connected to the support rods 12 through bearings, and the plurality of blades 13 are distributed in a fan blade pattern.

[0049] The shredder 11 crushes the large debris mixed in the water flow, making it easier for the debris to enter the diversion filter screen 7 for centralized cleaning.

[0050] As Figures 1 - 3 shown in the figure, the cleaning component 3 includes a sludge pump 14. The sludge pump 14 is connected to the bottom of the square frame plate 4 through a pipeline to suck out the impurities at the bottom of the filter screen component 2. The discharge port of the sludge pump 14 is connected to a garbage centralized treatment box 15 for collecting the impurities sucked out by the sludge pump 14. The sludge pump 14 is a prior art and will not be elaborated here.

[0051] As Figures 1 - 3 shown in the figure, the garbage centralized treatment box 15 includes a box body 17. A rectangular hole 18 is opened on one side of the box body 17. A filter screen A19 is installed on the rectangular hole 18 to filter and discharge the sewage entrained in the impurities, so that the garbage centralized treatment box 15 has the effect of separating dry and wet.

[0052] The utility model crushes the large debris mixed in the water flow through the shredder 11 on the filter screen component 2, making it easier for the debris to enter the diversion filter screen 7. The diversion filter screen 7 is arranged in a stepped manner, which can make the flowing water have a certain height difference. The water drives the debris to flow in a stepped manner inside the diversion filter screen 7 under the acceleration of gravity. Finally, the debris will be pressed to the bottom of the filter screen component 2 under the continuous water pressure. Then, the cleaning component 3 connected to the bottom of the filter screen component 2 will recycle and discharge the debris for cleaning, so that the overall device can automatically clean the garbage, achieving the effect of improving the garbage cleaning efficiency, and at the same time ensuring the normal operation of the gate, water quality safety and the service life of the gate filter screen.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
