Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides: A water quality detection sewage filtration device, as Figures 1 - 3 shown, includes an outer shell 1. A vibration motor 3 is installed on the upper surface of the outer shell 1. The output end of the vibration motor 3 is key-connected with a vibration rod 4. The vibration rod 4 penetrates through the top of the outer shell 1 and extends into the interior of the filter box 2. The bottom of the filter box 2 is connected and installed with a first sewage discharge pipe 7. An electric valve 8 is installed at the input end of the first sewage discharge pipe 7. A self-priming pump 9 is installed at the output end of the first sewage discharge pipe 7. An umbrella-shaped fine filter plate 10 is installed inside the outer shell 1 below the first sewage discharge pipe 7. A cleaning spray head 14 is fixedly installed on the upper surface of the fine filter plate 10. The input end of the cleaning spray head 14 penetrates through the rear side of the outer shell 1 and is connected to an external water pipe.

[0022] Preferably, several groups of limiting rods 5 are bolted to the outer surface of the filter box 2. The limiting rods 5 are bolted and installed inside the outer shell 1. The limiting rods 5 can fix the filter box 2 inside the outer shell 1. When starting the device, the vibration motor 3 will drive the vibration rod 4 to vibrate inside the filter box 2. The limiting rods 5 can fix the filter box 2 inside the device, preventing the filter box 2 from vibrating and displacing during the filtering process, and ensuring the safety of the device.

[0023] Furthermore, a baffle is fixedly installed on the left side of the housing 1, and the self-priming pump 9 is bolted to the upper surface of the baffle. The baffle fixes the self-priming pump 9 on the left side of the housing 1, facilitating the connection between the self-priming pump 9 and the first sewage discharge pipe 7. After the filter tank 2 filters the sewage, the electric valve 8 is opened. After the operator starts the self-priming pump 9, the self-priming pump 9 will extract the impurities inside the filter tank 2 and discharge them through the first sewage discharge pipe 7 to the external sewage tank, preventing the reduction of the filtering effect of the filter tank 2 due to the accumulation of impurities inside the filter tank 2.

[0024] Furthermore, a water inlet pipe 6 is connected and installed on the upper surface of the filter tank 2. The input end of the water inlet pipe 6 penetrates through the left side of the housing 1 and is connected to the sewage tank. The water inlet pipe 6 passes through the housing 1 and is connected to the filter tank 2, enabling the direct feeding of sewage into the filter tank 2, which is convenient for the filter tank 2 to perform the work of sewage filtration.

[0025] It is worth noting that a collector 12 is fitted and installed at the bottom of the fine filter plate 10, and a water outlet pipe 13 is tightly installed at the bottom of the collector 12. The output end of the water outlet pipe 13 penetrates through the right side of the housing 1 and is connected to the water storage tank. After the sewage is filtered by the fine filter plate 10, the filtered water will flow downward into the collector 12. The collector 12 is funnel-shaped, and the filtered water will flow along the inner wall of the collector 12 into the water outlet pipe 13 installed at the bottom, and finally flow to the water storage tank through the water pipe 13.

[0026] Specifically, a group of second sewage discharge pipes 11 are installed on both sides of the fine filter plate 10 respectively. The two groups of second sewage discharge pipes 11 penetrate through both sides of the housing 1 and are connected to the external sewage tank. Each group of second sewage discharge pipes 11 is respectively equipped with a valve 15. After the sewage is filtered by the filter tank 2 and flows out to the upper surface of the fine filter plate 10, impurities will remain on the upper surface after the fine filter plate 10 performs secondary filtration on the sewage. The cleaning nozzle 14 will wash the upper surface of the fine filter plate 10, and the impurities will flow along the surface of the fine filter plate 10 to the second sewage discharge pipe 11. When the valve 15 on the second sewage discharge pipe 11 is opened, the impurities will flow into the external sewage tank through the second sewage discharge pipe 11, thereby maintaining the filtering effect of the fine filter plate 10 and improving the working efficiency of the entire filtering device.

[0027] More specifically, a door 16 is hinged to the front side of the housing 1. A sealing ring 18 is installed on the side of the door 16 inside the housing 1. A handle 17 is fixedly installed on the front side of the door 16. By opening the door 16 through the handle 17, the state inside the housing 1 can be seen, and at the same time, the internal devices can be cleaned, maintained, and replaced. The sealing ring 18 on the side of the door 16 can make the entire device in a sealed state, and the internal water will not flow out during the filtering process.

[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
