[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to 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.
[0031] Refer to Figure 1 、 Figure 2 and Figure 4, An embodiment provided by the present utility model: A sand-water separator for a sewage treatment system, including a treatment tank 1, a top plate 2 is fixedly connected to the top of the treatment tank 1, a first motor 3 is fixedly connected to the top of the top plate 2, a circular groove 13 is opened inside the top plate 2, an adapter rod 14 is fixedly connected to the output end of the first motor 3, a plurality of stirring blades 15 are fixedly connected to the outside of the adapter rod 14, a sand settling port 4 is fixedly connected to the bottom of the treatment tank 1, a sand lifting pipeline 5 is fixedly connected to the bottom of the sand settling port 4, a second motor 7 is fixedly connected to the inside of one end of the sand lifting pipeline 5, a spiral blade 6 is fixedly connected to the output end of the second motor 7, a disassembly component is installed on one side of the treatment tank 1, an outlet 8 is fixedly connected to one end of the sand lifting pipeline 5, and a collection box 9 is fixedly connected to the bottom of the outlet 8.
[0032] Specifically, under the action of the water inlet 17, sewage enters the treatment tank 1. Thus, when the first motor 3 is started, the circular groove 13 plays a limiting role on the adapter rod 14, enabling the adapter rod 14 to rotate stably. In this way, the sewage in the treatment tank 1 is driven to rotate, so that the sand contained in the sewage sinks into the sand settling port 4, and the sand settling port 4 plays a fixing role on the sand lifting pipeline 5, so that the sand and gravel in the sand settling port 4 enter the sand lifting pipeline 5. Then, by starting the second motor 7, the second motor 7 plays a fixing role on the spiral blade 6, so that the spiral blade 6 rotates. In this way, under the action of the spiral blade 6, the sand and gravel in the sand lifting pipeline 5 are driven to rise. Thus, under the action of the outlet 8, the rising sand and gravel enter the collection box 9, and the sand and gravel in the sand-water can be quickly separated.
[0033] Refer to Figure 3 and Figure 4 , the disassembly component includes a fixing block 18, the outside of the fixing block 18 is fixedly connected to one side of the treatment tank 1, a water outlet 16 is fixedly connected to the inside of the fixing block 18, a limiting groove 23 is opened inside the fixing block 18, a moving slider 12 is slidably connected to the inner wall of the limiting groove 23, a pull rod 21 is fixedly connected to the inside of the moving slider 12, a spring 22 is sleeved on the outside of the pull rod 21, a connecting block 19 is slidably connected to the inner wall of the fixing block 18, a clamping groove 20 is opened on one side of the connecting block 19, the other end of the pull rod 21 is slidably connected to the inner wall of the clamping groove 20, a filter screen 24 is fixedly connected to the bottom of the connecting block 19, the longitudinal section of the pull rod 21 is circular, one end of the pull rod 21 is in plug-in fit with the clamping groove 20, one end of the spring 22 is fixedly connected to one side of the moving slider 12, and the other end of the spring 22 is fixedly connected to the inner wall of the limiting groove 23.
[0034] Specifically, the pull rod 21 fixes the moving slider 12. In this way, through the pull rod 21, the limiting groove 23 limits the moving slider 12. Thus, the moving slider 12 moves along the inner wall of the limiting groove 23, and one end of the pull rod 21 cooperates with the card slot 20, so that the other end of the pull rod 21 moves out of the card slot 20. Then, by pulling out the connecting block 19 upward, the connecting block 19 fixes the filter screen 24. In this way, the filter screen 24 can be taken out, and thus the cleaning process of the filter screen 24 can be conveniently carried out.
[0035] Refer to Figure 1 、 Figure 2 and Figure 4 , a water inlet 17 is fixedly connected to the top of the top plate 2. A valve is installed outside the water inlet 17. One end of the water outlet 16 is fixedly connected to one side of the treatment tank 1. A valve is installed outside the water outlet 16. A wear-resistant plate 11 is fixedly connected to the bottom inner wall of the sand lifting pipe 5. The other end of the spiral blade 6 is rotatably connected to one end of the sand lifting pipe 5. A support block 10 is fixedly connected to the outside of the sand lifting pipe 5.
[0036] Specifically, due to the function of the water inlet 17, sewage can enter the treatment tank 1 for treatment. Through the function of the valve outside the water outlet 16, the water source in the upper half of the treatment tank 1 can be discharged. The sand lifting pipe 5 fixes the wear-resistant plate 11. In this way, when the spiral blade 6 works, the friction loss of the sand on the sand lifting pipe 5 is reduced. And the support block 10 fixes the sand lifting pipe 5. In this way, when the spiral blade 6 works, the sand lifting pipe 5 can be made more stable.
[0037] Working principle: When it is necessary to separate sand and water from sewage, the sewage enters the treatment tank 1 through the water inlet 17. By starting the first motor 3, under the action of the circular groove 13, the connecting rod 14 can rotate stably, so that the sewage in the treatment tank 1 rotates, causing the sand contained in the sewage to sink into the sand settling port 4 and then enter the sand lifting pipeline 5. By starting the second motor 7, the spiral blade 6 is driven to rotate. Under the action of the spiral blade 6, the sand and gravel in the sand lifting pipeline 5 are driven to rise. Through the action of the sand outlet 8, the rising sand and gravel enter the collection box 9. Then, the stirring blade 15 is closed, and by opening the valve of the water outlet 16, the upper part of the water in the treatment tank 1 can be discharged, so that the separation of sand and water can be carried out quickly, thus improving the working efficiency. To prevent a small amount of sand and gravel from not being separated during drainage, the sand and gravel can be effectively separated through the filter screen 24. To prevent the filter screen 24 from being blocked due to long-term use, by means of the pull rod 21, the moving slider 12 is moved along the inner wall of the limit groove 23, so that the other end of the pull rod 21 moves out of the clamping groove 20. Then, by pulling out the connecting block 19 upward, the filter screen 24 can be taken out, thus facilitating the treatment of the filter screen 24.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
