Description

Technical Field

[0001] This utility model belongs to the field of sand filter technology, specifically relating to a V-shaped sand filter that is easy to clean. Background Technology

[0002] Sand filters are a common type of water treatment equipment, primarily used to remove suspended solids, colloids, silt, algae, and other impurities from water through physical filtration. Their core filter medium is quartz sand or other specific granular materials, which purify the water through the trapping and adsorption effects of the sand layer.

[0003] Existing V-shaped sand filters, which are easy to clean, require continuous water flushing of the quartz and fine sand filter layers to remove impurities. The flushing water is then directly discharged, resulting in a large water demand and waste of water resources. In addition, when cleaning the existing V-shaped sand filters by spraying water through the cleaning pipe, several through holes need to be made in the cleaning pipe. When the cleaning pipe is not in use, the through holes cannot be sealed and protected. During water purification, impurities can easily enter the cleaning pipe through the through holes, causing blockage. Utility Model Content

[0016] 1. This utility model, by setting up a collection component, allows impurities in the fine sand filter layer and quartz filter layer to be pushed out by the water flow. The motor then drives the rotating rod to rotate, which in turn drives the spiral blades. Water in the sand filter body is drawn into the folded pipe and discharged through the lower end of the rectangular box. Simultaneously, the filter plate intercepts impurities in the water, achieving the effect of filtering the water used for washing in the sand filter body and thus collecting the impurities. By setting up a cleaning component, the cleaned impurities can be collected, eliminating the need to continuously replenish water to the sand filter body to rinse the quartz filter layer and fine sand filter layer, saving water resources.

[0017] 2. This utility model, by setting up a protective component, allows the motor to be turned on when the cleaning tube is not in use, driving the rotating plate at one end of the rotating shaft to rotate. The rotation of the rotating plate causes the arc-shaped plate to rotate outside the cleaning tube. After the arc-shaped plate rotates to the upper end of the through hole, it can seal the through hole. By setting up the protective component, the through hole can be sealed and protected when the cleaning tube is not in use, preventing impurities from entering the cleaning tube through the through hole and causing blockage. At the same time, the fixed stop bar on the cleaning tube can play a positioning role for the movement of the arc-shaped plate, improving the accuracy of the arc-shaped plate's sealing position on the through hole.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5The present invention provides the following technical solution: a V-shaped sand filter that is easy to clean, comprising a sand filter body 1, an inlet pipe 4 provided on the upper side of one end of the sand filter body 1, an outlet pipe 8 provided on the lower side of the other end of the sand filter body 1, a pumping pipe 6 provided on the lower side of the inlet pipe 4, a water pump 5 provided on one end of the pumping pipe 6, a cleaning pipe 7 provided between the water pump 5 and the sand filter body 1, valves installed on the inlet pipe 4, the pumping pipe 6 and the outlet pipe 8, a quartz stone filter layer 9 provided on the lower side inside the sand filter body 1, a fine sand filter layer 10 provided on the upper end of the quartz stone filter layer 9, a protective component 3 provided in the quartz stone filter layer 9 at the position corresponding to the cleaning pipe 7, and a cleaning component 2 provided on the upper side inside the sand filter body 1.

[0027] Specifically, the cleaning component 2 includes a rectangular box 21, a folded tube 22, a filter plate 24, a motor 25, a rotating rod 26, and a spiral blade 27. The rectangular box 21 is located on the upper side inside the sand filter body 1. A folded tube 22 is fixed to the upper side of one end of the rectangular box 21. A motor 25 is installed at the position corresponding to the folded tube 22 at one end of the rectangular box 21. A rotating rod 26 is located at the output end of the motor 25. A spiral blade 27 is fixed on the rotating rod 26 inside the folded tube 22. A filter plate 24 is located on the lower side inside the rectangular box 21.

[0028] By adopting the above technical solution, after the impurities in the fine sand filter layer 10 and the quartz filter layer 9 are pushed out by the water flow, the motor 25 is turned on to drive the rotating rod 26 to rotate. The rotation of the rotating rod 26 drives the spiral blade 27 to rotate, and the water in the sand filter body 1 is sucked into the baffle 22. The water is discharged through the lower end of the rectangular box 21. At the same time, the filter plate 24 intercepts the impurities in the water, thereby achieving the effect of filtering the water used for washing in the sand filter body 1 and collecting the impurities. By setting the cleaning component 2, the cleaned impurities can be collected, eliminating the need to continuously replenish water to the sand filter body 1 to wash the quartz filter layer 9 and the fine sand filter layer 10, thus saving water resources.

[0029] Specifically, the cleaning component 2 also includes a protective box 23 and an auxiliary component 28. The protective box 23 is bolted to one end of the rectangular box 21 at the position corresponding to the motor 25. The filter plate 24 is connected to the rectangular box 21 through the auxiliary component 28.

[0030] By adopting the above technical solution, the protective box 23 can provide a sealing and protection function for the motor 25, preventing the motor 25 from entering the sand filter body 1 and being soaked in water.

[0031] Specifically, the auxiliary component 28 includes a fixed frame 281, a connecting frame 282, a second motor 283, a lead screw 284, a lifting plate 285, a locking block 286, a slot 287, a fixing bolt 288, and a fixing hole 289. The filter plate 24 is fixed with locking blocks 286 at both ends. The rectangular box 21 has a slot 287 at the lower end corresponding to the locking blocks 286. The locking blocks 286 and the rectangular box 21 are connected by fixing bolts 288. One end of the locking blocks 286 has a fixing hole 289 corresponding to the fixing bolts 288. The upper side of one end of the sand filter body 1 is fixed with a fixed frame 281. The second motor 283 is installed at the lower end of the fixed frame 281. The output end of the second motor 283 is provided with a lead screw 284. The lifting plate 285 is threadedly connected to the surface of the lead screw 284. The lifting plate 285 is connected to the rectangular box 21 through the connecting frame 282.

[0032] By adopting the above technical solution, when cleaning the filter plate 24, the motor 283 is turned on to drive the lead screw 284 to rotate. The rotation of the lead screw 284 causes the lifting plate 285 to move upward in the fixed frame 281. The lifting plate 285 drives the rectangular box 21 and the folded tube 22 to move out of the sand filter body 1 through the connecting frame 282. Then, the fixing bolt 288 is unscrewed from the fixing hole 289 of the locking block 286, and the filter plate 24 can be taken out from the lower side of the rectangular box 21. The locking block 286 is removed from the slot 287. By setting the auxiliary component 28, it is easy to remove and clean the filter plate 24 in the rectangular box 21, and avoid the filter plate 24 from clogging after long-term use.

[0033] Specifically, the side of the spiral blade 27 is tangent to the inner wall of the folded tube 22, the bend of the folded tube 22 is set as an arc structure, and the folded tube 22 and the rectangular box 21 are welded as a whole structure.

[0034] By adopting the above technical solution, the side of the spiral blade 27 fits more closely to the inner wall of the folded tube 22, and the bend of the folded tube 22 is set with an arc-shaped structure to facilitate the guidance and transportation of water.

[0035] Specifically, the rectangular box 21 has through holes at both ends of the lower side corresponding to the fixing bolts 288. After the filter plate 24 is installed into the rectangular box 21, the side of the filter plate 24 is in close contact with the inner wall of the rectangular box 21.

[0036] By adopting the above technical solution, the fixing bolt 288 can be inserted into the rectangular box 21 and screwed into the fixing hole 289 of the clip 286. After the filter plate 24 is installed into the rectangular box 21, the side of the filter plate 24 fits more closely with the inner wall of the rectangular box 21.

[0037] Specifically, one end of the lifting plate 285 is tightly attached to one end of the fixed frame 281. The lifting plate 285 has a threaded hole corresponding to the lead screw 284. The connecting frame 282 and the rectangular box 21, as well as the connecting frame 282 and the lifting plate 285, are all spot welded together.

[0038] By adopting the above technical solution, the rotation of the lead screw 284 can drive the lifting plate 285 to move on the fixed frame 281. One end of the lifting plate 285 is in close contact with one end of the fixed frame 281, which plays a limiting role for the lifting plate 285.

[0039] In this embodiment, the V-shaped sand filter is easy to clean. When using it, the device is installed in a suitable location. For water purification, wastewater is discharged into the sand filter body 1 through the inlet pipe 4. The fine sand filter layer 10 and quartz filter layer 9 in the sand filter body 1 filter and purify the wastewater, which is then discharged from the sand filter body 1 through the outlet pipe 8. When it is necessary to clean impurities from the fine sand filter layer 10 and quartz filter layer 9, the valve on the outlet pipe 8 is closed, an appropriate amount of water is injected into the sand filter body 1, and the water pump 5 is turned on to pump water through the suction pipe 6. Water in the sand filter body 1 is fed into the cleaning pipe 7. The cleaning pipe 7 sprays a water jet from bottom to top through the through-hole 11, flushing out impurities from the fine sand filter layer 10 and the quartz filter layer 9, thus cleaning these layers. After the impurities are pushed out by the water flow, the motor 25 is activated to drive the rotating rod 26 to rotate. The rotating rod 26 drives the spiral blade 27 to rotate, drawing water from the sand filter body 1 into the bend pipe 22. The water is discharged through the lower end of the rectangular box 21, while the filter plate 24 intercepts impurities in the water, thus filtering the water used for washing in the sand filter body 1 and collecting the impurities. The cleaning component 2 can collect the cleaned impurities, eliminating the need to continuously add water to the sand filter body 1 to rinse the quartz filter layer 9 and the fine sand filter layer 10, saving water resources. The auxiliary component 28 allows the motor 283 to be turned on to rotate the lead screw 284 when cleaning the filter plate 24 is required. 284 rotates, causing the lifting plate 285 to move upward in the fixed frame 281. The lifting plate 285 drives the rectangular box 21 and the folded tube 22 to move out of the sand filter body 1 through the connecting frame 282. Then, the fixing bolt 288 is unscrewed from the fixing hole 289 of the locking block 286, and the filter plate 24 can be taken out from the lower side inside the rectangular box 21. The locking block 286 is removed from the slot 287. The auxiliary component 28 is set to facilitate the removal and cleaning of the filter plate 24 in the rectangular box 21, and to avoid the filter plate 24 from clogging after long-term use.

[0040] Example 2

[0041] The difference between this embodiment and embodiment 1 is that the protective component 3 includes a cavity 31, a mesh frame 32, a motor 33, a rotating shaft 34, a rotating plate 35, and an arc-shaped plate 36. The quartz filter layer 9 has a cavity 31 at the position corresponding to the cleaning pipe 7. The mesh frame 32 is installed in the cavity 31. The motor 33 is installed at one end of the sand filter body 1 at the position corresponding to the cleaning pipe 7. The output end of the motor 33 is provided with a rotating shaft 34. The other end of the rotating shaft 34 is fixed with a rotating plate 35. One end of the rotating plate 35 is fixed with an arc-shaped plate 36 at the position corresponding to the cleaning pipe 7.

[0042] By adopting the above technical solution, when the cleaning tube 7 is not in use, the motor 33 is turned on to drive the rotating plate 35 at one end of the rotating shaft 34 to rotate. The rotation of the rotating plate 35 drives the arc plate 36 to rotate outside the cleaning tube 7. After the arc plate 36 rotates to the upper end of the through hole 11, it can seal the through hole 11. By setting the protective component 3, the through hole 11 can be sealed and protected when the cleaning tube 7 is not in use, so as to prevent impurities from entering the cleaning tube 7 through the through hole 11 and causing the through hole 11 to be blocked.

[0043] Specifically, baffles 37 are fixed on both sides of the cleaning pipe 7, the inner side of the arc plate 36 is tangent to the surface of the cleaning pipe 7, and one end of the rotating plate 35 is offset from the inner wall of the mesh frame 32.

[0044] By adopting the above technical solution, fixing the stop bar 37 on the cleaning pipe 7 can play a positioning role in the movement of the arc plate 36, thereby improving the accuracy of the sealing position of the arc plate 36 to the through hole 11.

[0045] Specifically, the gap size of the mesh frame 32 is smaller than the size of the quartz particles in the quartz filter layer 9, and the mesh frame 32 is made of stainless steel.

[0046] By adopting the above technical solution, quartz particles in the quartz filter layer 9 are prevented from entering the mesh frame 32. The mesh frame 32 is made of stainless steel, making it more robust and durable.

[0047] In this embodiment, when the cleaning tube 7 is not in use, the motor 33 is turned on to drive the rotating plate 35 at one end of the rotating shaft 34 to rotate. The rotation of the rotating plate 35 causes the arc plate 36 to rotate outside the cleaning tube 7. After the arc plate 36 rotates to the upper end of the through hole 11, it can seal the through hole 11. By setting the protective component 3, the through hole 11 can be sealed and protected when the cleaning tube 7 is not in use, so as to prevent impurities from entering the cleaning tube 7 through the through hole 11 and causing the through hole 11 to be blocked. At the same time, the fixed stop bar 37 on the cleaning tube 7 can play a positioning role in the movement of the arc plate 36, improving the accuracy of the sealing position of the arc plate 36 on the through hole 11.

[0048] In this utility model, the motor-25 is a previously disclosed technology, and the selected model is Z60-55ZY.

[0049] In this utility model, the motor 283 is a previously disclosed technology, and the selected model is 50GASRZ.

[0050] In this utility model, the motor 33 is a previously disclosed technology, and the selected model is 5IK120GN-CF.

[0051] The structure and working principle of the sand filter body 1, inlet pipe 4, water pump 5, pumping pipe 6, cleaning pipe 7, outlet pipe 8, quartz filter layer 9 and fine sand filter layer 10 of this utility model have been disclosed in an aquaculture sand filter disclosed in Chinese patent application number 2018115611190.

[0052] The working principle and usage process of this utility model are as follows: When using the V-shaped sand filter that is easy to clean, the device is installed in a suitable position. For water purification, wastewater is discharged into the sand filter body 1 through the inlet pipe 4. The fine sand filter layer 10 and quartz filter layer 9 in the sand filter body 1 filter and purify the wastewater, which is then discharged from the sand filter body 1 through the outlet pipe 8. When it is necessary to clean the impurities in the fine sand filter layer 10 and quartz filter layer 9, the valve on the outlet pipe 8 is closed, and an appropriate amount of water is injected into the sand filter body 1. The water pump 5 is turned on, and the water in the sand filter body 1 is transported into the cleaning pipe 7 through the pumping pipe 6. The cleaning pipe 7 sprays a water column from bottom to top through the through hole 11 to remove the impurities from the fine sand filter body 1. Impurities in filter layer 10 and quartz filter layer 9 are flushed out, thus cleaning the impurities in the fine sand filter layer 10 and quartz filter layer 9. After the impurities in the fine sand filter layer 10 and quartz filter layer 9 are pushed out by the water flow, the motor 25 is turned on to drive the rotating rod 26 to rotate. The rotation of the rotating rod 26 drives the spiral blade 27 to rotate, and the water in the sand filter body 1 is drawn into the baffle pipe 22. The water is discharged through the lower end of the rectangular box 21. At the same time, the filter plate 24 intercepts the impurities in the water, achieving the effect of filtering the washing water in the sand filter body 1 and collecting the impurities. The cleaning component 2 can be set to collect the cleaned impurities without the need for manual collection. Continuing to replenish water into the sand filter body 1, the quartz filter layer 9 and the fine sand filter layer 10 are rinsed, saving water resources. By setting up auxiliary component 28, when cleaning the filter plate 24 is required, motor 283 is turned on to rotate the lead screw 284. The rotation of the lead screw 284 causes the lifting plate 285 to move upward in the fixed frame 281. The lifting plate 285, through the connecting frame 282, moves the rectangular box 21 and the folded pipe 22 out of the sand filter body 1. Then, the fixing bolt 288 is unscrewed from the fixing hole 289 of the locking block 286, allowing the filter plate 24 to be removed from the lower side inside the rectangular box 21. The locking block 286 is removed from the slot 287. The auxiliary component 28 facilitates this process. Remove and clean the filter plate 24 in the rectangular box 21 to prevent the filter plate 24 from clogging after long-term use. When the cleaning tube 7 is not in use, turn on the motor 33 to drive the rotating plate 35 at one end of the rotating shaft 34 to rotate. The rotation of the rotating plate 35 causes the arc plate 36 to rotate outside the cleaning tube 7. After the arc plate 36 rotates to the upper end of the through hole 11, it can seal the through hole 11. By setting the protective component 3, the through hole 11 can be sealed and protected when the cleaning tube 7 is not in use, preventing impurities from entering the cleaning tube 7 through the through hole 11 and causing blockage of the through hole 11. At the same time, the fixed stop bar 37 on the cleaning tube 7 can play a positioning role for the movement of the arc plate 36, improving the accuracy of the sealing position of the arc plate 36 on the through hole 11.
