[0020] Compared with the prior art, the water supply tank with dual filtering function has the following beneficial effects:

[0021] 1. The water supply tank with dual filtering function uses a sedimentation and filtering tank to pump water into the tank body through a water inlet pipe, and the water in the tank body flows into the water supply tank body through a stainless steel filter and a water outlet hole for storage. In the process, multiple water outlet holes are shielded by multiple inclined partitions to extend the flow path of the water flow, and the flow rate of the water flow is reduced by multiple water outlet holes, so that the silt in the water in the tank body is difficult to be brought into the water supply tank body under the action of the water flow. The silt with larger mass in the water settles on the surface of multiple inclined partitions and slides down, which is conducive to the sedimentation of the silt in the water to the bottom of the tank body. The silt sediment at the bottom of the tank body is discharged to the outside of the water supply tank body through a sewage pipe A to preliminarily separate the silt in the water and ensure the separation effect of water and silt. After the preliminarily separated water is filtered through the stainless steel filter in the water outlet hole, it enters the water supply tank body, which can greatly reduce the silt content in the water in the water supply tank body and slow down the accumulation of silt in the water supply tank body.

[0022] 2. Based on the above principles and effects, the water supply tank with dual filtering function discharges the sediment at the bottom of the tank body to the outside of the water supply tank body through the sewage pipe A in the sedimentation and filtration tank. The sediment at the bottom of the tank body will impact the impeller with the water flow to make it rotate. At the same time, the torque of the impeller is amplified by gears A and B and the crankshaft is driven to rotate, which can make the connecting rod move up and down, and then drive the bar rod up and down through the connecting rod, which can make the brush plate move up and down to achieve the cleaning effect of the stainless steel filter screen to ensure the filtering capacity of the stainless steel filter screen. Moreover, when the bar rod moves up and down, the spring A fixedly connected between the bar rod and the inclined partition can also make the inclined partition vibrate, so that the sediment remaining on the surface of the inclined partition slides down, and at the same time, the cleaning effect of the upper surface of the inclined partition is achieved. In summary, while the sewage is discharged from the tank body, the stainless steel filter screen and the inclined partition in the sedimentation and filtration tank can also be cleaned, further ensuring the water quality in the water supply tank body and reducing the sediment content in the water in the water supply tank body.

[0023] 3. The self-cleaning filter of the present invention can filter the water twice through the filter cylinder when supplying water to the water pipe. In addition, the impurities intercepted in the filter cylinder can be discharged through the sewage pipe B. In the process of discharging impurities, the rotating tube can also rotate under the action of the water flow. When the rotating tube rotates, it drives multiple fixing frames and brush cylinders to rotate together, and the brush cylinder can rotate on the inner wall of the filter cylinder, so that the filter cylinder can be cleaned to avoid the filter cylinder from being blocked, ensure the filtering capacity of the filter cylinder, and reduce the consumption of filter materials.

[0024] 4. Based on the above principles and effects, when the brush cylinder at the water inlet hole rotates, it will also rotate on its own, that is, the brush cylinder will rotate on the outer surface of the round rod. At this time, the slider fixed on the inner wall of the brush cylinder will slide inside the wave groove, so that the brush cylinder can rotate and vibrate up and down at the same time, thereby improving the cleaning effect of the brush cylinder on the filter cylinder and further ensuring the filtering capacity of the filter cylinder.

[0025] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] See also Figure 1-16 The present invention provides a technical solution: a water supply tank with dual filtering functions, comprising a water supply tank body 1, a sedimentation filter tank 2 and a self-cleaning filter 3, the sedimentation filter tank 2 comprises a tank body 201 fixed to the inner wall of the water supply tank body 1, the main body of the tank body 201 is a hollow rectangular parallelepiped, and its bottom end is a pyramid shape, the top end of the tank body 201 extends to the top of the water supply tank body 1 and is connected to a water inlet pipe 202.

[0057] Water is pumped into the bin 201 through the water inlet pipe 202 and then flows into the water supply tank 1 for storage. A liquid level controller is provided inside the water supply tank 1. The liquid level controller keeps the water in the water supply tank 1 at a high water level according to the working state of the water pump at the input end of the water inlet pipe 202.

[0058] The bottom end of the bin body 201 is fixedly connected with a drain pipe A203, and the drain pipe A203 extends to the outside of the water supply box 1. The end of the drain pipe A203 away from the bin body 201 is connected with a drain valve A2036, and the drain valve A2036 is located outside the water supply box 1. By opening the drain valve A2036, the mud and sediment at the bottom of the bin body 201 can be discharged through the drain pipe A203.

[0059] Please refer to Figure 2 to Figure 6 A group of water outlet holes 204 are provided on the left and right side walls of the warehouse body 201. The water outlet holes 204 are rectangular. A stainless steel filter screen 205 is fixed inside the water outlet holes 204. The stainless steel filter screen 205 preferably uses 400-500 meshes. Two groups of inclined partitions 208 corresponding to the positions of the two groups of water outlet holes 204 are provided inside the warehouse body 201. The top of the inclined partition 208 is fixed on the inner wall of the water supply box body 1, the top of the inclined partition 208 is located above the corresponding water outlet hole 204, and the bottom of the inclined partition 208 is located below the corresponding water outlet hole 204.

[0060] In the above scheme, water is pumped into the silo 201 through the water inlet pipe 202, and the water in the silo 201 is filtered through the stainless steel filter 205, and then flows into the water supply box 1 through the water outlet 204 for storage. It should be noted that the water in the water supply box 1 is in a high water level range. In the process, the multiple water outlets 204 are shielded by multiple inclined partitions 208 to extend the flow path of the water flow, and the multiple water outlets 204 are used to reduce the flow rate of the water flow, so that the silt in the water in the silo 201 is difficult to be brought into the water supply box 1 under the action of the water flow. The silt with a larger mass in the water settles on the surface of the multiple inclined partitions 208 and slides down, which is conducive to the sedimentation of the silt in the water to the bottom of the silo 201. The silt sediment at the bottom of the silo 201 is discharged to the outside of the water supply box 1 through the sewage pipe A203 to preliminarily separate the silt in the water and ensure the separation effect of water and silt. The initially separated water is filtered through the stainless steel filter 205 in the water outlet 204 and then enters the water supply box 1 , which can significantly reduce the sediment content in the water in the water supply box 1 and slow down the accumulation of sediment in the water supply box 1 .

[0061] Strip holes 209 are provided on the end surfaces of the two groups of inclined partitions 208 that are close to each other, a support frame 206 is fixed on the inner wall of the bottom of the warehouse body 201, and a strip rod 207 is slidably set in the middle of the support frame 206. The top end of the strip rod 207 slides through multiple strip holes 209 and slides through the top wall of the warehouse body 201 to the top of the warehouse body 201, and springs A210 are fixed on the ends of the two groups of inclined partitions 208 that are close to each other, and the bottom end of each spring A210 is fixed to the strip rod 207 through a connecting block.

[0062] A brush plate 211 is slidably provided on one side of each stainless steel filter screen 205 close to the strip rod 207 , and each brush plate 211 is fixedly connected to the strip rod 207 via a fixing rod 212 .

[0063] Please refer to Figure 3 , Figure 7 and Figure 8An impeller chamber is provided at the top of the sewage pipe A203, and an impeller 2031 is rotatably provided inside the impeller chamber, one end of the rotating rod of the impeller 2031 penetrates to the outside of the sewage pipe A203 and is fixed with a gear A2032, and the rotating rod of the impeller 2031 is rotatably provided on the pipe wall of the sewage pipe A203, and a crankshaft 2033 is rotatably provided inside the top of the sewage pipe A203, and a connecting rod 2034 is rotatably provided on the journal of the crankshaft 2033, and the top of the connecting rod 2034 is hinged to the bottom end of the strip rod 207, one end of the crankshaft 2033 penetrates to the outside of the bin body 201 and is fixed with a gear B2035, and the crankshaft 2033 is rotatably provided on the pipe wall of the sewage pipe A203, and the gear B2035 is meshed with the gear A2032, and the number of teeth of the gear B2035 is at least five times that of the gear A2032.

[0064] In the above scheme, opening the drain valve A2036 can make the mud and sand at the bottom of the bin 201 be discharged to the outside of the water supply box 1 through the drain pipe A203. In the process of mud and sand discharge, the mud and sand at the bottom of the bin 201 will impact the impeller 2031 with the water flow to make it rotate, and at the same time, the torque of the impeller 2031 is amplified through the gear A2032 and the gear B2035 to drive the crankshaft 2033 to rotate, so that the connecting rod 2034 can move up and down, and then the connecting rod 2034 drives the bar 207 to move up and down, so that the brush plate 211 can move up and down, so as to achieve the cleaning effect of the stainless steel filter 205, so as to ensure the filtering capacity of the stainless steel filter 205. When the strip rod 207 moves up and down, the inclined partition 208 can also be vibrated by the spring A210 fixedly connected between the strip rod 207 and the inclined partition 208, so that the mud and sand remaining on the surface of the inclined partition 208 slides downward, and at the same time the upper surface of the inclined partition 208 is cleaned.

[0065] For further solutions, please refer to Figure 3 and Figure 4 The top of the strip rod 207 is sleeved with a spring B2071, the top of the spring B2071 is fixedly connected to the top of the strip rod 207, and the bottom of the spring B2071 is fixedly connected to the top surface of the bin body 201. The spring B2071 is provided to provide elastic support for the strip rod 207 to balance the gravity of the strip rod 207, the plurality of fixed rods 212 and the plurality of brush plates 211, thereby reducing the adverse effect of the weight of the related structural parts on the movement of the strip rod 207.

[0066] Please refer to Figure 1 , Fig. 9 and Fig.10 The self-cleaning filter 3 is fixedly connected to the water outlet at the bottom of the water supply box 1. The self-cleaning filter 3 includes a sealing shell 301. The sealing shell 301 is connected to the water outlet of the water supply box 1 through multiple water inlet holes 302 opened on the top surface thereof.

[0067] A water supply pipe 303 is fixedly connected to the side wall of the sealed shell 301 , and water is supplied to the water pipe through the water supply pipe 303 . A filter cylinder 305 is installed inside the sealed shell 301 , and the filter cylinder 305 is located below the water inlet hole 302 .

[0068] When water is supplied to the water pipe through the water supply pipe 303, the water in the water supply box 1 enters the interior of the filter cylinder 305 through the water inlet hole 302, and after being filtered by the filter cylinder 305, it flows into the water pipe through the water supply pipe 303, so that the water can be filtered twice.

[0069] Please refer to Figure 10 to Figure 14 A material discharge hole 306 is provided on the bottom surface of the sealing shell 301, and a sealing plate 307 for sealing the material discharge hole 306 is fixed on the bottom surface of the sealing shell 301. A sewage pipe B308 is fixed in the middle of the sealing plate 307. The sewage pipe B308 is used to discharge impurities intercepted in the filter cylinder 305. A sewage valve B304 is fixed at the bottom end of the sewage pipe B308 for controlling the sewage discharge state of the sewage pipe B308.

[0070] A rotating pipe 309 is rotatably sleeved on the top of the sewage pipe B308, and a material discharging cavity 3091 connected to the sewage pipe B308 is provided inside the rotating pipe 309. The outer surface of the rotating pipe 309 is provided with multiple groups of drainage holes 3092 in a circular array about the axis of the rotating pipe 309, and the drainage holes 3092 penetrate into the material discharging cavity 3091, and the tangent of the intersection of the drainage holes 3092 and the circle formed by the cross section of the rotating pipe 309 is not perpendicular.

[0071] Open the drain valve B304 and discharge the impurities intercepted in the filter cylinder 305 through the drain pipe B308. In the process, the impurities intercepted in the filter cylinder 305 flow out to the outside of the sealing shell 301 through the drain hole 3092, the material removal cavity 3091 and the drain pipe B308 along with the water flow. Because the tangent of the intersection of the circle formed by the cross section of the drain hole 3092 and the rotating tube 309 is not perpendicular, when the water flows through the drain hole 3092, the rotating tube 309 can be rotated.

[0072] A plurality of fixing frames 310 are fixed to the outer surface of the rotating tube 309 , and a round rod 311 parallel to the inner side surface of the filter cylinder 305 is fixed to one end of the sealing shell 301 away from the rotating tube 309 . A brush cylinder 312 is rotatably sleeved on the outer surface of the round rod 311 , and the brush cylinder 312 contacts the inner side wall of the filter cylinder 305 .

[0073] When rotating, the rotating tube 309 drives the multiple fixing frames 310 and the brush cylinder 312 to rotate together, so that the brush cylinder 312 can rotate on the inner wall of the filter cylinder 305, so as to clean the filter cylinder 305 to avoid the filter cylinder 305 from being blocked, ensure the filtering capacity of the filter cylinder 305, and thus reduce the consumption of filter materials.

[0074] Please refer to Fig.15 and Fig.16 A circle of wave groove 3111 is formed on the outer surface of the round rod 311 , and the wave groove 3111 is arranged around the outer surface of the round rod 311 . A slider 3121 is fixed to the inner wall of the brush cylinder 312 , and the slider 3121 is slidably arranged in the wave groove 3111 .

[0075] Because there is a certain friction between the brush cylinder 312 and the inner wall of the filter cylinder 305, the brush cylinder 312 will also rotate when it rotates, that is, the brush cylinder 312 will rotate on the outer surface of the round rod 311. At this time, the slider 3121 fixed on the inner wall of the brush cylinder 312 will slide inside the wave groove 3111, so that the brush cylinder 312 can vibrate up and down while rotating, thereby improving the cleaning effect of the brush cylinder 312 on the filter cylinder 305, further ensuring the filtering capacity of the filter cylinder 305, and reducing the consumption of filter materials.

[0076] For further solutions, please refer to Figure 10 to Figure 12 A plurality of limiting rods 313 are fixed between the inner top wall and the inner bottom wall of the sealing shell 301, and the plurality of limiting rods 313 are distributed in an annular shape. The filter cylinder 305 is slidably arranged between the plurality of limiting rods 313, and the filter cylinder 305 can be moved out to the outside of the sealing shell 301 through the material removal hole 306; the sealing plate 307 is fixed to the bottom surface of the sealing shell 301 by bolts and squeezes and fixes the filter cylinder 305, and the sealing plate 307 and the sealing shell 301 are sealed by a rubber pad, and the inner top wall of the sealing shell 301 is provided with a limiting hole 314, and the limiting hole 314 is located between the plurality of water inlet holes 302, and the top end of the rotating tube 309 can be rotatably arranged inside the limiting hole 314. Through this scheme, the detachable assembly between the filter cylinder 305, the sealing plate 307, the sewage pipe B308, the rotating tube 309 and the sealing shell 301 can be realized, which is convenient for cleaning and maintenance of the components in the self-cleaning filter 3.

[0077] The working principle has been shown in order above. It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
