DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 5 The utility model provides a technical solution: a purification device with a solid-liquid separation structure, including a feed inlet 1, the feed inlet 1 is fixedly connected to one side of the top of a cylinder 2, the middle of the top of the cylinder 2 is vertically penetrated by the output end of a driving motor 3, the output end of the driving motor 3 is fixedly electrically connected to a filter barrel 4, the top of the filter barrel 4 is fixedly connected to a filter screen plate 5, the inner wall of the cylinder 2 is embedded with a filtering device 6, the bottom wall of the inner wall of the cylinder 2 is fixedly connected to a water outlet pipe 7, the bottom end of the water outlet pipe 7 is fixedly connected to a water storage tank 8, one side of the water storage tank 8 is fixedly connected to a water pump 9, the water outlet end of the water pump 9 is fixedly connected to a reverse osmosis device 10, and one side of the reverse osmosis device 10 is fixedly connected to a pure water tank 11.
[0022] In this embodiment, Figure 4As shown, the filter barrel 4 is provided with an outer wall and an inner wall, and the outer wall and the inner wall are provided with a plurality of mesh holes, and the interlayer between the outer wall and the inner wall is filled with a quartz sand filter element 401. It should be noted that when the external water source is connected to the feed port 1, the sewage enters the interior of the cylinder 2 through the feed port 1, and the sewage will first contact the filter screen plate 5 when entering the interior of the cylinder 2, and the large-diameter holes provided on the filter screen plate 5 can pre-filter the large solid particles in the sewage, and the sewage after preliminary filtration will fall into the filter barrel 4 located directly below it again, and the operator can start the drive motor 3 at this time, so that the output end of the drive motor 3 starts to rotate, and drives the rotating shaft 301 fixedly connected thereto to rotate together, and because the bottom end of the rotating shaft 301 is fixedly connected to the bottom wall of the inner wall of the filter barrel 4, the entire filter barrel 4 will also be driven to rotate together. At the same time, the sewage falling into the filter barrel 4 at this time will be close to the inner wall of the filter barrel 4 due to the centrifugal force generated during the high-speed rotation of the filter barrel 4. The filtered sewage will pass through the mesh holes opened on the inner wall of the filter barrel 4 and penetrate into the quartz sand filter element 401 in the interlayer of the filter barrel 4, thereby filtering out the mud, impurities and suspended matter in the sewage and reducing the pollution index density value of the sewage. The filtered sewage will pass through the mesh holes opened on the outer wall of the filter barrel 4 again and fall into the bottom wall of the cylinder 2, and fall into the filter device 6 by gravity.
[0023] In this embodiment, Figure 3 As shown, the interior of the filter device 6 is divided into two levels of filter layers, which are activated carbon filter layer 601 and resin particle filter layer 602 from top to bottom. It should be noted that the sewage that has been filtered out of impurities by the quartz sand filter element 401 in the inner wall interlayer of the filter barrel 4 will fall into the interior of the filter device 6 due to gravity. Because the filter device 6 is divided into two levels of filter layers, when the sewage enters the interior of the filter device 6, it will first be filtered by the activated carbon filter layer 601 to filter out chemical organic matter, heavy metals, chroma, chlorine, etc. in the sewage, and the odor in the sewage will also be adsorbed and removed. Then, the sewage that has passed the primary filtration will flow down and enter the resin particle filter layer 602. Through the exchange treatment of sodium-type cations, calcium, magnesium and other ions in the sewage are removed, thereby softening the water quality, which can effectively prevent the formation of scale. After completing the primary and secondary filtration, the soft raw water will flow into the bottom wall of the cylinder 2 again along the mesh at the bottom of the filter device 6, and finally be discharged from the outlet pipe 7.
[0024] In this embodiment, Figure 2 and Figure 3As shown, a hollow ring 201 is fixedly connected to the inner wall of the cylinder 2, and a raised ring 603 is provided on the top of the filter device 6, wherein the raised ring 603 can be embedded in the inside of the hollow ring 201, so that the filter device 6 is installed on the inner wall of the cylinder 2. It should be noted that a circular ring is provided on the top of the filter device 6, and a plurality of protrusions are provided on the surface of the circular ring, thereby forming a protruding circular ring 603, and a circular ring is also fixedly connected to the inner wall of the cylinder 2, but a plurality of annular through holes are opened on the surface of the circular ring, and the plurality of protrusions provided on the protruding circular ring 603 and the plurality of annular through holes opened on the surface of the hollow circular ring 201 are of the same shape and number. Therefore, the operator can first insert the filter device 6 equipped with a two-stage filter element into the annular through holes opened by the hollow circular ring 201 through the protrusions provided on the protruding circular ring 603 one by one, thereby embedding the entire filter device 6 into the inner wall of the cylinder 2, and filtering the sewage entering the cylinder 2. After using the water purification equipment for a period of time, since the two layers of filter elements in its filter device 6 have reached a saturated state, the operator can open the cylinder 2 and take out the filter device 6 from the inside of the cylinder 2 at any time, thereby replacing the filter element inside it. This process is simple to operate and convenient and fast.
[0025] In this embodiment, Figure 1 and Figure 5 As shown, the reverse osmosis device 10 is provided with three reverse osmosis round tanks, and reverse osmosis RO membranes 1001 are bonded to the inner walls of the three reverse osmosis round tanks. It should be noted that after the sewage inside the cylinder 2 has been filtered for impurities by the quartz sand filter element 401, the odor has been removed by the activated carbon filter layer 601, and the water quality has been softened by the resin particle filter layer 602, the soft raw water will fall into the water storage tank 8 through the outlet pipe 7 on the inner wall of the cylinder 2. At the same time, the operator can start the pump 9 to extract the softened sewage in the water storage tank 8 and transport it to the pump 9, and then to the reverse osmosis device 10 fixedly connected on the other side of the pump 9. At this time, the soft raw water will pass through the three reverse osmosis round tanks in turn, and pass through in turn. The reverse osmosis RO membrane 1001 inside the reverse osmosis round tank performs deep separation treatment, thereby removing colloids, suspended solids, microorganisms, bacteria and other organic matter in the water, as well as heat sources, viruses and other substances in the water. At this time, after the sewage has undergone the first three levels of filtration treatment, the water that is harmful to human health is excluded, and pure water is produced after being treated by the reverse osmosis RO membrane 1001. At the same time, the pure water flows into the pure water tank 11 fixedly connected on one side along the connecting water pipe of the outer frame of the reverse osmosis device 10 through the action of water pressure and gravity, thereby completing the purification of the sewage.
[0026] In this embodiment, Figure 2As shown, the output end of the driving motor 3 is fixedly connected with a rotating shaft 301, and the bottom end of the rotating shaft 301 is fixedly connected to the bottom wall of the inner wall of the filter barrel 4. At the same time, the filter barrel 4 and the driving motor 3 form a rotating mechanism through the rotating shaft 301. It should be noted that when the operator connects the external water source to the feed port 1, the sewage enters the interior of the cylinder 2 along the feed port 1. At the same time, the sewage will first pass through the filter screen plate 5 to filter out the large particles of solid therein, completing the preliminary solid-liquid separation, and then the sewage will fall into the filter barrel 4 located directly below the filter screen plate 5 under the action of gravity. Because in the filter barrel 4, at the same time, the operator can start the driving motor 3, so that the output end of the driving motor 3 starts to rotate, because the output end of the driving motor 3 is fixedly connected with the rotating shaft 301, and the rotating shaft 301 is fixedly connected to the bottom wall of the filter barrel 4, so the entire filter barrel 4 will rotate together under the drive of the rotating shaft 301, and because the driving motor 3 is always in a high-speed rotation process during this process. , so that the filter barrel 4 will generate centrifugal force during the continuous rotation, and the liquid part of the sewage falling into the filter barrel 4 will be adsorbed on the inner wall of the filter barrel 4 due to the centrifugal force, and penetrate into the quartz sand filter element 401 in its interlayer through the mesh holes opened on the inner wall of the filter barrel 4, thereby performing secondary impurity filtration, and the filtered sewage will pass through the mesh holes opened on the outer wall of the filter barrel 4 again, and then fall into the filter device 6 located directly below the filter barrel 4, and perform fine filtration again. During the rotation process of the filter barrel 4 just now, most of the solid particles in the sewage will be retained in the filter barrel 4. After completing several sewage purifications, the operator can clean up the solid particles retained in the filter barrel 4, thereby facilitating the next sewage filtration.
[0027] The use method and advantages of the utility model: When the purification equipment with a solid-liquid separation structure is used, the working process is as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, when the operator connects the external water source to the feed port 1, the sewage enters the interior of the cylinder 2 along the feed port 1. At the same time, the sewage will first pass through the filter screen plate 5 to filter out the large solid particles therein, completing the preliminary solid-liquid separation, and then the sewage will fall into the filter barrel 4 located directly below the filter screen plate 5 under the action of gravity. Because in the filter barrel 4, at the same time, the operator can start the drive motor 3 to make the output end of the drive motor 3 start to rotate, because the output end of the drive motor 3 is fixedly connected to the rotating shaft 301, and the rotating shaft 301 is fixedly connected to the bottom wall of the filter barrel 4, so the entire filter barrel 4 will Driven by the rotating shaft 301, the filter barrel 4 rotates together. Since the driving motor 3 is in a high-speed rotation process during this process, the filter barrel 4 will generate centrifugal force during the continuous rotation. Most of the solid particles in the sewage will be retained inside the filter barrel 4, while the liquid part will be adsorbed on the inner wall of the filter barrel 4 due to the centrifugal force, and penetrate into the quartz sand filter element 401 in its interlayer through the mesh holes opened on the inner wall of the filter barrel 4, thereby performing secondary impurity filtration. The filtered sewage will pass through the mesh holes opened on the outer wall of the filter barrel 4 again, and then fall into the filter device 6 arranged directly below the filter barrel 4. It passes through the activated carbon filter layer 601 in sequence to remove chemical organic matter, heavy metals, color, odor, etc. in the sewage, and then enters the resin particle filter layer 602. Through the exchange treatment of sodium-type cations, calcium, magnesium and other ions in the sewage are removed, thereby softening the water quality and effectively preventing the formation of scale. After completing the primary and secondary filtration, the soft raw water will flow into the bottom wall of the cylinder 2 again along the bottom mesh of the filter device 6, and be discharged from the outlet pipe 7 to the water storage tank 8. At the same time, the operator can start the pump 9 to extract the softened sewage in the water storage tank 8 and transport it to the pump 9. And in the reverse osmosis device 10 fixedly connected to the other side of the water pump 9, at this time, the soft raw water will be sequentially subjected to the deep separation treatment of the reverse osmosis RO membrane 1001 inside the three reverse osmosis round tanks, thereby removing the colloids, suspended matter, microorganisms, bacteria and other organic matter in the water, as well as heat sources, viruses and other substances in the water. At this time, after the sewage has been filtered through the first three levels, the water that is harmful to human health is excluded, and pure water is produced. At the same time, the pure water flows into the pure water tank 11 fixedly connected on one side along the connecting water pipe of the outer frame of the reverse osmosis device 10 through the action of water pressure and gravity, thereby completing the purification of the sewage.
