[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] Embodiment:
[0027] Please refer to Figures 1-6 , the present invention provides a technical solution:
[0028] A sewage purification device in the field of water conservancy projects includes a processing tank 1. The right end of the top of the processing tank 1 is fixedly installed with a water treatment agent adding cylinder 2. The bottom of the water treatment agent adding cylinder 2 is connected to the inside of the processing tank 1 through a connecting pipe 3. A filter assembly 4 is installed inside the processing tank 1. The filter assembly 4 includes a first filter screen 5, a second filter screen 6 and a third filter screen 7. The first filter screen 5, the second filter screen 6 and the third filter screen 7 are installed inside the processing tank 1 from top to bottom in sequence. Waste collection covers 8 are fixedly installed on both the left and right sides of the processing tank 1 and outside the first filter screen 5 and the second filter screen 6. It further includes:
[0029] A cleaning assembly 9 is fixedly installed on the front of the processing tank 1. The cleaning assembly 9 is used to clean the tops of the first filter screen 5 and the second filter screen 6.
[0030] First, support feet 101 are fixedly installed at the four corners of the bottom of the treatment tank 1. A sewage inlet pipe 102 is fixedly connected to the top of the treatment tank 1. A drain pipe 103 is fixedly installed at the bottom end of the front of the treatment tank 1. A valve is provided on the drain pipe 103. The treatment tank 1 is supported and elevated by multiple groups of support feet 101 to protect the bottom of the treatment tank 1 from getting damp. When purifying sewage, the sewage is introduced through the sewage inlet pipe 102 at the top of the treatment tank 1, and then the treated water is discharged from the drain pipe 103.
[0031] Further, a cylinder cover 201 is rotatably connected to the top of the water treatment agent adding cylinder 2. An electromagnetic valve 202 is fixedly installed between the water treatment agent adding cylinder 2 and the connecting pipe 3. An installation bracket 301 is fixedly installed on the top of the treatment tank 1 and outside the connecting pipe 3. A first motor 302 is fixedly installed on the top of the installation bracket 301. The output end of the first motor 302 extends into the connecting pipe 3 and is fixedly connected to a rotating shaft 303. The bottom end of the rotating shaft 303 is fixedly connected to a dredging fan blade 304. When the water treatment agent adding cylinder 2 is not in use, the cylinder cover 201 is closed. When purifying sewage, the cylinder cover 201 is opened to add the water treatment agent. During this process, the addition amount can be observed through the liquid level window on the outside of the water treatment agent adding cylinder 2. After adding a fixed amount of water treatment agent, the electromagnetic valve 202 is started to discharge, and it is introduced into the inside of the treatment tank 1 through the connecting pipe 3 and mixed with the sewage. During the addition of the water treatment agent, the rotating shaft 303 inside the first motor 302 is started for dredging to prevent blockage inside the connecting pipe 3.
[0032] Then, one end of the connecting pipe 3 located inside the treatment tank 1 is fixedly connected to a communicating pipe 305. Drain heads 306 are threadedly connected to both the left and right ends of the communicating pipe 305. Multiple groups of discharge holes 307 are equally spaced at the bottom end of the drain head 306. A box door 308 is rotatably connected to the front end of the top of the treatment tank 1. When the connecting pipe 3 adds the water treatment agent into the inside of the treatment tank 1, when the water treatment agent is introduced into the inside of the treatment tank 1 through the connecting pipe 3, it enters the communicating pipe 305, and then the water treatment agent is evenly introduced into the inside of the treatment tank 1 through the discharge holes 307 outside the drain head 306, thus avoiding the problem that the water treatment agent is uniformly added in one place and not evenly mixed with the sewage, and further improving the mixing effect of the water treatment agent and the sewage. Subsequently, the box door 308 can also be opened to repair and replace the drain head 306 to avoid problems such as blockage affecting its use.
[0033] Furthermore, the first filter screen 5, the second filter screen 6 and the third filter screen 7 are all movably inserted into the interior of the treatment tank 1. The aperture of the second filter screen 6 is larger than that of the first filter screen 5. The third filter screen 7 is an activated carbon filter screen. A maintenance door 701 is fixedly installed at a position on the front of the treatment tank 1 corresponding to the third filter screen 7. After the sewage is introduced into the interior of the treatment tank 1, it is preliminarily filtered by the first filter screen 5, and then secondary filtered by the second filter screen 6. Finally, when passing through the third filter screen 7, the activated carbon filter screen adsorbs polluting substances such as small molecule organic substances leaking from the previous stage, and adsorbs and removes odors, colloids, pigments, heavy metal ions, etc. in the water. By performing multi-stage filtration and purification on the sewage, the purification effect of the sewage is guaranteed. At the same time, the maintenance door 701 is fixed to the outside of the treatment tank 1 by studs, and the third filter screen 7 can be removed from the interior of the treatment tank 1, which is convenient for disassembly and replacement.
[0034] Wherein, waste discharge ports 801 are provided between the waste collection cover 8 and the first filter screen 5 and the second filter screen 6. A collection box 802 is slidably connected inside the waste collection cover 8. And a first filter screen 5 is fixedly installed at the bottom end inside the collection box 802 on the outer side of the first filter screen 5, and a second filter screen 6 is fixedly installed at the bottom end inside the collection box 802 on the outer side of the second filter screen 6. A material guiding cover 803 is fixedly installed at the bottom of the waste collection cover 8. The bottom of the material guiding cover 803 is connected to the interior of the treatment tank 1 through a return pipe 804. After the first filter screen 5 and the second filter screen 6 are used for a long time, the filter holes are likely to be blocked. At this time, the cleaning assembly 9 is used to remove the blockages on the surfaces of the first filter screen 5 and the second filter screen 6, so that the filter holes can be dredged under the scouring of the sewage. The removed blockages will be shoveled into the collection box 802 inside the waste collection cover 8 through the waste discharge port 801. The collection box 802 can be pulled out, so as to collect and process the blockages. At the same time, the water in the blockages entering the collection box 802 will be normally filtered through the corresponding filter screen at the bottom, and the sewage accidentally entering the collection box 802 will also be filtered. The filtered water will be re-introduced into the interior of the treatment tank 1 from the return pipe 804 under the guidance of the material guiding cover 803.
[0035] Secondly, the cleaning component 9 includes a support plate 901 fixedly installed on the front of the processing box 1. At both the left and right ends of the top of the support plate 901, support frames 902 are fixedly installed. A guiding column 903 is rotatably connected between the two groups of support frames 902. A second motor 904 is fixedly installed at the left end of the top of the support plate 901, and the output end of the second motor 904 is fixedly connected to the left end of the guiding column 903. A moving rod 905 is slidably connected between the two groups of support frames 902 and below the guiding column 903. At the positions corresponding to the first filter screen 5 and the second filter screen 6 on the front of the processing box 1, protective covers 906 are fixedly installed. Inside both groups of protective covers 906, connecting rods 907 are slidably connected. At one end of the two groups of connecting rods 907 inside the processing box 1 and on the top of the first filter screen 5 and the second filter screen 6, shoveling plates 908 are fixedly connected. At one end of the two groups of connecting rods 907 outside the processing box 1, they are fixedly connected to the moving rod 905 through a transmission rod 909. The left and right ends of the protective cover 906 are fixed by studs, and the first filter screen 5 and the second filter screen 6 can be removed from the inside of the processing box 1, which is convenient for disassembly and replacement.
[0036] Finally, at the front and rear ends of the inner sides of the two groups of support frames 902, sliding rods 910 are fixedly connected, and the moving rod 905 is slidably connected to the sliding rods 910. At the top of the rear end of the moving rod 905, a guiding slider 911 is fixedly connected. The guiding slider 911 is slidably connected to the guiding column 903 through a guiding groove 912. When purifying sewage, start the second motor 904 to drive the guiding column 903 to rotate. Under the guidance of the guiding groove 912 on the outer side of the guiding column 903, drive the guiding slider 911 to slide. Since the moving rod 905 is slidably connected to the sliding rod 910, when the guiding slider 911 slides, it drives the moving rod 905 to move left and right reciprocally, thereby driving the transmission rod 909 to slide left and right, causing the connecting rod 907 inside the protective cover 906 to slide accordingly, and then driving the shoveling plate 908 to remove the blockages on the surfaces of the first filter screen 5 and the second filter screen 6. This not only reduces the cleaning difficulty of the staff, but also ensures the purification effect of the first filter screen 5 and the second filter screen 6 on sewage, and correspondingly improves the purification efficiency of sewage.
[0037] In this embodiment, the implementation scenario is specifically as follows: When purifying sewage, the sewage is introduced through the sewage inlet pipe 102 at the top of the treatment tank 1. When purifying the sewage, the cylinder cover 201 is opened to add water treatment agent, which is introduced into the interior of the treatment tank 1 through the guiding of the connecting pipe 3 and mixed with the sewage. After the sewage is introduced into the interior of the treatment tank 1, it is preliminarily filtered by the first filter screen 5, then subjected to secondary filtration by the second filter screen 6, and finally when passing through the third filter screen 7, the activated carbon filter screen adsorbs contaminating substances such as small molecule organic substances leaking from the previous stage, adsorbs and removes odors, colloids, pigments, heavy metal ions, etc. in the water. Through multi-stage filtration and purification of the sewage, the purification effect of the sewage is guaranteed. After the first filter screen 5 and the second filter screen 6 are used for a long time, the filter holes are likely to be blocked. The second motor 904 is started to drive the guiding column 903 to rotate. Under the guiding of the guiding groove 912 on the outer side of the guiding column 903, the guiding slider 911 slides. Since the moving rod 905 is slidably connected to the sliding rod 910, when the guiding slider 911 slides, it drives the moving rod 905 to reciprocate left and right, thereby driving the transmission rod 909 to slide left and right, causing the connecting rod 907 inside the protective cover 906 to slide accordingly, and then driving the shovel plate 908 to remove the blockages on the surfaces of the first filter screen 5 and the second filter screen 6, so that the filter holes can be dredged under the flushing of the sewage. The removed blockages are shoveled into the collection box 802 in the waste collection cover 8 through the waste discharge port 801, and the collection box 802 can be pulled out to collect and process the blockages. At the same time, the water in the blockages entering the collection box 802 will be normally filtered through the corresponding filter screen at the bottom, and the sewage accidentally entering the collection box 802 will also be filtered. The filtered water will be re-introduced into the interior of the treatment tank 1 from the return pipe 804 under the guiding of the material guiding cover 803. The whole operation process is simple and convenient. Compared with the existing sewage purification equipment in the field of hydraulic engineering, through the design of the present utility model, not only the cleaning difficulty of the staff is reduced, but also the purification effect of the sewage is guaranteed, and the purification efficiency of the sewage is correspondingly improved.
