Description

Technical Field

[0001] The present invention relates to the field of filtration technology, in particular to a method for controlling water flow rate of filtration equipment. Background Art

[0002] Mine water pollution refers to mining industrial wastewater and domestic sewage containing various pollutants and toxic substances. After being discharged into the water body, its normal composition is changed, exceeding the self-purification capacity of the water and unable to be completely purified. In order to avoid the deterioration of the water body, it is necessary to meet the construction specifications of ecological protection projects and use high-efficiency activated carbon and other filter materials to filter and treat mine wastewater to avoid negative impacts on the ecological environment after the wastewater is discharged.

[0003] Existing filtering equipment usually uses separation, sedimentation boxes or filtering equipment to filter solid particles in sewage when filtering mine sewage. Since sewage is directly introduced into the separation box, sedimentation box or filtering equipment during the filtering process, and sewage is directly pumped into the filter cavity, the solid particles in the sewage will collide with the filter material (such as filter screen, filter cloth, high-efficiency activated carbon, etc.) in the filter cavity under the impact of the water flow, thereby causing the filter screen to deform or displace, directly affecting the filtering effect. In response to the above problems, there are already good solutions in the existing technology, such as a low-voltage environmentally friendly condensation filtering device with publication number CN118634558B, which generates a weak current by outputting a low voltage through the provision of a first electrode, a second electrode and a grounding part, so that a potential difference is generated between the first electrode and the second electrode and between the second electrode and the grounding part, so that impurities are aggregated under the influence of the electric field change, and the provision of a filter sub-barrel is used to perform pre-filtration treatment on the sewage, thereby preventing the sewage from quickly entering the filter cavity and affecting the filtering effect. However, the following defects still exist: as the filtration work continues, some solid particles in the mine wastewater will be retained in the filter sub-barrel. On the one hand, the gradual blockage of the filter sub-barrel will cause the flow rate of the sewage out of the filter sub-barrel to be unstable, affecting the flow rate of the sewage into the filter cavity, causing the filter material in the filter cavity to be subjected to uneven impact force, thereby destroying the original pore structure of the filter material, and thus affecting the filtration effect; on the other hand, the unstable flow rate will cause uneven water flow distribution in the filter cavity, resulting in deviations in the filtration effect in local areas of the filter material.

[0004] Therefore, in order to solve the above problems, a method for controlling water flow rate of a filtering device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for controlling the water flow rate of a filtering device, which solves the problem that the blockage of the filter sub-barrel affects the water flow rate and the uniformity of the water flow distribution, thereby reducing the filtering effect. By providing an adjustment component, a filtering component and a pumping component, the position of the water inlet pipe is continuously adjusted during the process of supplying water to the interior of the filter tank and the position of the corresponding filter plate is synchronously adjusted, so that no matter which side of the partition the water inlet pipe is located on, a corresponding filter plate can be used for filtering, and the filter plate located on the other side of the partition is moved to the end position of the filter tank and folded downward under the action of the adjustment component, thereby achieving automatic cleaning of impurities; and the water after preliminary filtration can assist in driving the normal operation of the adjustment component during the process of being pumped into the interior of the filter barrel, reducing the resistance of the adjustment component while automatically adjusting the water flow rate by using the pressure difference and elastic deformation, so that the flow rate of the water after entering the filter barrel is within a stable range and the water flow distribution range is expanded, avoiding the situation where the local flow rate is too fast or too slow, and effectively ensuring the filtering effect of the filter barrel.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] and a filter element for filtering water. The filter element is connected to the filter element by a thread-type filter element and a filter element for filtering water. The filter element is connected to the filter element by a thread-type filter element and a filter element for filtering water. The filter element is connected to the filter element by a thread-type filter element and a filter element for filtering water.

[0008] Preferably, the adjustment assembly includes a motor, a mounting frame, a screw rod 1, a screw rod 2, a synchronous wheel, a synchronous belt, a slider and a movable plate. The motor and the mounting frame are both arranged on the filter tank, the screw rod 1 is arranged through the filter tank and is connected to the output end of the motor, the screw rod 2 is arranged on the mounting frame, there are two synchronous wheels and they are respectively arranged at the ends of the screw rod 1 and the screw rod 2, the two synchronous wheels are connected by a synchronous belt transmission, the screw rod 1 and the screw rod 2 are both reciprocating screw rods, the slider is arranged on the screw rod 1, and the movable plate is arranged on the screw rod 2, and the movement directions of the slider and the movable plate are opposite.

[0009] By adopting the above scheme, the synchronous rotation of screw rod one and screw rod two is realized by utilizing the set synchronous belt and two synchronous wheels, and the slider and the movable plate are driven to move in opposite directions at the same speed during the synchronous rotation of screw rod one and screw rod two, so that when the water inlet pipe moves from the end to the middle of the filter tank, the filter assembly in the opposite direction is driven to move synchronously toward the middle of the filter tank, and when the water inlet pipe moves from the middle to the end of the green grass, the filter assembly in the opposite direction is driven to be misaligned with the filter tank, so as to achieve the effect of intermittently blocking the corresponding water leaks by the two filter assemblies, thereby realizing the preliminary filtration of the water flowing out of the water inlet pipe, and then ensuring the filtering effect of the filter barrel.

[0010] Preferably, the filter assembly includes a mounting plate, a filter plate, a guide groove, a guide plate, a magnetic block and a receiving box. The mounting plate is slidably arranged at the bottom of the filter tank, and the filter plate is hingedly arranged on one side of the mounting plate. When the filter plate is in a horizontal state, it is in contact with the edge of the water tank and the bottom of the filter tank. The guide groove is opened on the outer wall of the filter tank, the guide plate is arranged at the end of the mounting plate and is slidably connected to the guide groove, the magnetic block is arranged on the guide plate, the movable plate is a magnetic plate and is slidably fitted with the outer wall of the filter tank, and the receiving box is arranged on the water tank.

[0011] By adopting the above scheme, the two filter plates are set up and placed under the corresponding water leakage ports respectively, which can preliminarily filter the impurity particles in the water flowing out of the corresponding water leakage ports respectively, and the two filter plates can automatically move along with the movement of the water inlet pipe, respectively blocking or opening the corresponding water leakage ports in an intermittent motion manner, and at the same time can be folded downward in the process of opening the corresponding water leakage ports to discharge impurities on the surface of the filter plate to ensure the filtering effect during the next filtration, thereby effectively stabilizing the flow rate of water flowing into the water tank, preventing larger particles of impurities from entering the water tank and affecting the filtering effect of the filter barrel, and can also realize automatic cleaning of the filter plate, thereby ensuring the filtering effect of the filter plate.

[0012] Preferably, the pumping assembly includes a water pump, a hollow column, a guide pipe, a guide member and a diverter member. The water pump is arranged in a water tank. An impeller is rotatably arranged inside the hollow column. The impeller is fixedly connected to the two ends of the screw rod. The water outlet of the guide pipe and the water inlet of the guide member are symmetrically arranged on the hollow column. The lower end of the guide pipe is connected to the water pump. The guide member passes through the filter barrel and has an inner diameter larger than the inner diameter of the guide pipe. The diverter member is arranged in the filter barrel and connected to the guide member. When water enters the filter barrel from the guide member, it impacts the diverter member and drives the diverter member to rotate.

[0013] By adopting the above scheme, when the water pump is pumping the water after the initial filtration into the interior of the filter barrel, the water flow can enter the interior of the hollow column along the rotation direction of the screw 2 and hit the impeller, thereby increasing the rotation trend of the screw 2 to ensure the synchronous rotation between the two synchronous wheels. At the same time, the difference in the inner diameters of the guide tube and the guide member can be used to slow down the flow rate of the water after entering the filter barrel, avoiding the large impact force generated by the excessive flow rate after the water enters the filter barrel and affecting the filter element, thereby ensuring the filtering effect of the filter barrel.

[0014] Preferably, the guide member includes section one, section two and section three, section one passes through the interior of the hollow column, section two passes through the interior of the filter barrel and its two ends are respectively connected to section one and section three, the inner diameter of section two is larger than the inner diameter of section one, and the inner diameter of section three is smaller at the top and larger at the bottom, a fixed plate is provided at the bottom of section three, a connecting rod is passed through the interior of the fixed plate, a plug is provided at the upper end of the connecting rod, the plug is truncated in a cone shape, a spring is provided between the plug and the fixed plate, and the spring is sleeved on the connecting rod.

[0015] It can be seen that the filter plate will not completely filter out the impurities in the water. Some impurities will still pass through the filter plate and follow the water flow into the inside of the water tank, causing the water pump to be affected by the impurities during the pumping process, resulting in an unstable flow rate after the water enters the inside of section one. Therefore, this solution is adopted. By setting a plug and a spring inside section three, when the water flow speed pumped by the water pump increases, it will impact the plug to cause the spring to contract and expand the gap between the plug and the inner wall of section three, thereby slowing down the outflow speed of the water; when the water flow speed pumped by the water pump decreases, the spring squeezes the plug through its own elastic force, reducing the gap between the plug and the inner wall of section three, thereby increasing the outflow speed of the water, so that the water flow remains within a flow rate range after entering the filter barrel. The water flow will not fluctuate greatly after entering the filter barrel due to the influence of impurities on the input end of the water pump. The flow rate is self-regulated through physical properties such as pressure difference and elastic deformation, avoiding dependence on electronics or algorithms while effectively ensuring the filtering effect of the filter barrel.

[0016] Preferably, the diverter is arranged in a trumpet shape and has a plurality of guide plates arranged in a circular array on the outer wall, and a retaining edge is provided at the edge of each guide plate.

[0017] By adopting the above scheme, when the water flows from the lower end of section three to the surface of the diverter, the impact force of the water flow can be used to impact the surface of the diverter, and the guide plate and the baffle drive the diverter to rotate, so that the diverter is in a rotating state, so as to evenly distribute the water entering the filter barrel on the surface of the filter element, thereby ensuring the filtering effect of the filter barrel, and the pores of the filter element in the filter barrel are arranged in a gradient and the pores gradually decrease from top to bottom, which can further improve the filtering effect of the filter barrel.

[0018] Preferably, the surface circumferential array of the diverter element has multiple groups of water outlet holes, and the distance between the water outlet holes and the axis of the flow guide element is proportional to the aperture of the water outlet holes.

[0019] By adopting the above solution, a part of the water flow can flow out from the inside of the corresponding water outlet hole during the process of flowing on the surface of the diverter, and the water flowing out of the water outlet hole will not flow out in large quantities because the water outlet hole is close to the axis of the guide member, so that the water entering the filter barrel can be distributed more evenly when it comes into contact with the filter element, further ensuring the filtering effect of the filter barrel.

[0020] A control method applicable to the water flow rate control device of the above-mentioned filtering equipment comprises the following steps:

[0021] S1. Start the motor, which drives the screw rod to rotate and drives the water inlet pipe to move back and forth horizontally above the filter tank;

[0022] S2, screw 2 rotates synchronously with screw 1 under the action of the synchronous belt and two synchronous wheels and adjusts the positions of the two filter plates intermittently, so that impurities on the surface of one filter plate can be automatically cleaned while the other filter plate is filtering;

[0023] S3, start the water pump, the water pump pumps the water in the water tank into the filter barrel and assists in driving the second screw to rotate;

[0024] S4, before the water flows into the filter barrel, the plug and spring adjust the flow rate of the water through pressure difference and elastic deformation;

[0025] S5. After the water flows into the filter barrel, it drives the diverter to rotate and expand the water flow distribution range.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Through the setting of the adjustment component and the two filter components, the positions of the two filter components can be continuously adjusted in conjunction with the movement of the water inlet pipe during the process of supplying water to the inside of the filter tank, so that when one of the filter components is performing the filtering operation, the other filter component automatically folds over and cleans the impurities filtered on its surface. While performing continuous filtration treatment, it can avoid the larger impurities in the water causing the filter tank to be blocked and affecting the water flow rate, so that the filter barrel can stabilize the water flow rate on the basis of continuous filtration treatment, thereby ensuring the filtering effect of the filter barrel.

[0028] 2. Through the provided pumping assembly, the impeller can be impacted in the process of pumping the water after the initial filtration in the water tank into the inside of the filter barrel, so that the impeller auxiliary screw 2 rotates, reducing the transmission resistance between the two synchronous belts to ensure the service life. At the same time, the change in the inner diameter of segment 1 and segment 2 can be used to slow down the water flow rate. At the same time, under the action of the plug and the spring, the pressure difference and the elastic deformation of the spring can be used to continuously adjust the distance between the plug and the inner wall of segment 3 in accordance with the water flow rate, so as to avoid uneven impact force on the filter element in the filter barrel due to unstable flow rate when the water flow contacts the filter element, thereby ensuring the service life of the filter element while also ensuring the filtering effect of the filter barrel.

[0029] 3. By setting up the diverter and utilizing the rotational connection between the diverter and the connecting rod, the diverter can be driven to rotate by the impact force of the water flow after the water flows out from section three, and the water flow is separated from the diverter by the guide plate and the baffle during the rotation of the diverter to form a swirl diffusion effect. At the same time, with the multiple groups of water outlet holes opened on the surface of the diverter, the aperture difference of the water outlet holes is utilized to expand the distribution range of the water flow and make the water flow distribution more uniform, avoiding uneven water distribution and causing the local flow velocity of the water flowing through the filter element to be too fast or too slow, thereby further ensuring the filtering effect of the filter barrel.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0049] See also Figures 1 to 10 The present invention provides a method for controlling the water flow rate of a filtering device, and the technical solution is as follows:

[0050] For details, please refer to Figure 1 and Figure 2A method for controlling the flow rate of water in a filtering device includes a filter barrel 1, a water tank 2, a filter tank 3, a water inlet pipe 4, an adjusting component 5, a filtering component 6, and a pumping component 7. The water tank 2 is arranged on the filter barrel 1, the filter tank 3 is arranged in the water tank 2, the water inlet pipe 4 runs through the filter tank 3, a partition 31 is arranged inside the filter tank 3, and two water leakage ports 32 are symmetrically opened at the bottom of the filter tank 3. The adjusting component 5 is arranged on the filter tank 3 and connected to the water inlet pipe 4. Two filtering components 6 are provided and both are arranged on the filter tank 3. The adjusting component 5 When powered on, the water inlet pipe 4 is driven to move back and forth horizontally. When the water outlet of the water inlet pipe 4 moves from one end of the filter tank 3 to the center position, it drives the filter assembly 6 at the other end to move below the corresponding water leakage port 32. When the water outlet of the water inlet pipe 4 moves from the center position to the other end of the filter tank 3, it drives the filter assembly 6 at the opposite position to be misaligned with the corresponding water leakage port 32. The pumping assembly 7 is arranged in the water tank 2 and is connected to the driving assembly and the filter barrel 1. When the pumping assembly 7 is powered on, it transports water to the inside of the filter barrel 1 and distributes it in a vortex in the filter barrel 1.

[0051] As an embodiment of the present invention, refer to Figure 1 and Figure 2 The adjustment component 5 includes a motor 51, a mounting frame 52, a screw rod 1 53, a screw rod 2 54, a synchronous wheel 55, a synchronous belt 56, a slider 57 and a movable plate 58. The motor 51 and the mounting frame 52 are both arranged on the filter tank 3. The screw rod 1 53 is arranged through the filter tank 3 and is connected to the output end of the motor 51. The screw rod 2 54 is arranged on the mounting frame 52. There are two synchronous wheels 55 and they are respectively arranged at the ends of the screw rod 1 53 and the screw rod 2 54. The two synchronous wheels 55 are connected by a synchronous belt 56. The screw rod 1 53 and the screw rod 2 54 are both reciprocating screw rods. The slider 57 is arranged on the screw rod 1 53, and the movable plate 58 is arranged on the screw rod 2 54. The movement directions of the slider 57 and the movable plate 58 are opposite.

[0052] Under the above setting conditions, after the motor 51 is powered on and started, the output end of the motor 51 drives the screw rod 1 53 to rotate. When the screw rod 1 53 rotates, it drives the synchronous wheel 55 at its end to rotate. Since the two synchronous wheels 55 are connected by a synchronous belt 56, the two synchronous wheels 55 can be used to drive the screw rod 2 54 to rotate synchronously during the rotation of the screw rod 1 53. Since the screw rod 1 53 and the screw rod 2 54 are both reciprocating screw rods, when the screw rod 1 53 rotates, it can drive the slider 57 to drive the water inlet pipe 4 to move back and forth horizontally at a uniform speed above the filter tank 3, and the partition 31 in the filter tank 3 is opened. Under the action, the water entering the filter tank 3 is divided into two parts, and the two parts of water can flow out from the corresponding water leakage port 32 respectively, and flow through the corresponding filter components 6 respectively. At the same time, during the rotation of screw rod 1 53 and screw rod 2 54, the slider 57 and the movable plate 58 simultaneously move in opposite directions. During the movement, the movable plate 58 drives the corresponding filter component 6 to move horizontally at the bottom of the filter tank 3, so that when one filter component 6 is working, the impurities on the other filter component 6 can be automatically cleaned, thereby eliminating the need for manual intervention and effectively ensuring continuous filtration efficiency.

[0053] As an embodiment of the present invention, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9 The filter assembly 6 includes a mounting plate 61, a filter plate 62, a guide groove 63, a guide plate 64, a magnetic block 65 and a receiving box 66. The mounting plate 61 is slidably arranged at the bottom of the filter tank 3, and the filter plate 62 is hingedly arranged on one side of the mounting plate 61. When the filter plate 62 is in a horizontal state, it is fitted with the edge of the water tank 2 and the bottom of the filter tank 3, wherein the filter plate 62 is slidingly and sealingly fitted with the bottom of the filter tank 3 to ensure the sealing of the filter plate 62 during filtration and prevent water from flowing out of the gap between the filter tank 3 and the filter plate 62. The guide groove 63 is opened on the outer wall of the filter tank 3, the guide plate 64 is arranged at the end of the mounting plate 61 and is slidably connected to the guide groove 63, the magnetic block 65 is arranged on the guide plate 64, the movable plate 58 is a magnetic plate and is slidably fitted with the outer wall of the filter tank 3, and the receiving box 66 is arranged on the water tank 2.

[0054] Under the above setting conditions, the water in the filter tank 3 will flow through the surface of the corresponding filter plate 62 after flowing out from the corresponding water leakage port 32 and finally fall into the water tank 2, and the larger particles of impurities in the water will be filtered by the filter plate 62. When the screw rod 1 53 drives the water inlet pipe 4 from the end position of the filter tank 3 to the middle position through the slider 57, the screw rod 2 54 attracts the corresponding magnetic block 65 from the other end of the filter tank 3 to the middle position of the filter tank 3 through the magnetic force between the moving plate 58 and the magnetic block 65. Since the magnetic block 65 is set on the guide plate 64, and the guide plate 64 is slidably set in the guide groove 63 and connected to the mounting plate 61, the magnetic block 65 follows the movement. During the movement of the movable plate 58, the mounting plate 61 can be driven to move synchronously. Since the mounting plate 61 is hinged with the filter plate 62, the movement of the mounting plate 61 can also drive the filter plate 62 to move. During the movement of the filter plate 62, it will be blocked by the water tank 2 and rotate with the hinge with the mounting plate 61 as the rotation axis until it rotates to fit the bottom of the filter tank 3 and continues to move with the mounting plate 61 until the guide plate 64 moves to the end position of the corresponding guide groove 63 (in this process, the filter plate 62 at the other end of the bottom of the filter tank 3 is always located below the corresponding water leakage port 32). After the block, the screw rod 53 continues to rotate under the drive of the motor 51, and the water inlet pipe 4 will move from one side of the partition 31 to the other side. During this process, the moving plate 58 separates from the corresponding magnetic block 65 and contacts with another magnetic block 65. As the screw rod 53 continues to rotate, the moving plate 58 can push the magnetic block 65 that is in contact with it to move under the action of the two synchronous wheels 55 and the synchronous belt 56. The magnetic block 65 can push the corresponding filter plate 62 to move through the corresponding guide plate 64 and the mounting plate 61 in turn, until the filter plate 62 is separated from the water tank 2 and folds downward under the action of its own gravity, and in the process of folding, it can make the water filtered on its surface Impurities automatically fall into the interior of the corresponding receiving box 66, thereby realizing automatic cleaning of impurities. The depth of the filter screen embedded in the filter plate 62 increases from the middle position of the filter tank 3 to the end position of the filter tank 3. It can prevent the bottom of the filter tank 3 from pressing impurities into the interior of the filter screen embedded in the filter plate 62 during the horizontal movement of the filter plate 62, so that impurities gather on the surface of the filter screen embedded in the filter plate 62. At the same time, an opening 621 is provided on the surface of the filter plate 62 to prevent water adsorbed on the surface of the filter plate 62 from dispersing in the process of following the reciprocating movement of the filter plate 62, and can make the impurities on the surface of the filter plate 62 effectively fall into the interior of the corresponding receiving box 66 when the filter plate 62 is folded downward.

[0055] As an embodiment of the present invention, refer to Figure 1 、 Figure 3 and Figure 4The pumping assembly 7 includes a water pump 71, a hollow column 72, a guide pipe 73, a guide member 74 and a diverter 75. The water pump 71 is arranged in the water tank 2. The hollow column 72 is provided with an impeller 721 for rotation. The impeller 721 is fixedly sleeved with the end of the screw rod 54. The water outlet of the guide pipe 73 and the water inlet of the guide member 74 are symmetrically arranged on the hollow column 72. The lower end of the guide pipe 73 is connected to the water pump 71. The guide member 74 penetrates into the filter barrel 1 and has an inner diameter larger than the inner diameter of the guide pipe 73. The diverter 75 is arranged in the filter barrel 1 and connected to the guide member 74. When water enters the filter barrel 1 from the guide member 74, it impacts the diverter 75 and drives the diverter 75 to rotate.

[0056] Under the above-mentioned setting conditions, when the water pump 71 is powered on, the water in the water tank 2 is pumped to the inside of the hollow column 72 through the guide tube 73 and impacts the impeller 721, thereby assisting the screw 2 54 to rotate, and preventing the movable plate 58 from damaging the synchronous belt 56 due to excessive resistance when pulling the magnetic block 65. After entering the interior of the hollow column 72, the water flow will flow into the interior of the filter barrel 1 through the guide member 74 for final filtration treatment. Since the inner diameter of the guide member 74 is larger than the inner diameter of the guide tube 73, the water pressure after flowing into the interior of the guide member 74 will decrease, that is, the water flow speed will decrease, thereby avoiding the water flow speed entering the filter barrel 1 being too high and affecting the filtration effect.

[0057] As an embodiment of the present invention, refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The guide member 74 includes section 1 741, section 2 742 and section 3 743. Section 1 741 passes through the interior of the hollow column 72, section 2 742 passes through the interior of the filter barrel 1 and its two ends are respectively connected to section 1 741 and section 3 743. The inner diameter of section 2 742 is larger than the inner diameter of section 1 741, and the inner diameter of section 3 743 is smaller at the top and larger at the bottom. A fixing plate 7431 is provided at the bottom of section 3 743, and a connecting rod 7432 is passed through the interior of the fixing plate 7431. A plug 7433 is provided at the upper end of the connecting rod 7432. The plug 7433 is truncated in a cone shape. A spring 7434 is provided between the plug 7433 and the fixing plate 7431, and the spring 7434 is sleeved on the connecting rod 7432.

[0058] Under the above-mentioned setting conditions, when the impurities in the water tank 2 gradually increase and the water flow rate pumped by the water pump 71 increases, the water flow from the inside of section two 742 to the inside of section three 743 will impact the plug 7433. After being impacted by the water flow, the plug 7433 will move downward, thereby increasing the gap between the plug 7433 and section three 743, and thus reducing the flow rate of the water flowing out of section three 743; when the impurities in the water tank 2 gradually increase and the water flow rate pumped by the water pump 71 decreases, the elastic force of the spring 7434 will overcome the impact force of the water flow on the plug 7433 and drive the plug 7433 to move upward, thereby reducing the gap between the plug 7433 and section three 743, and thus increasing the speed of the water flowing out of section three 743, so that the water flow always remains in a relatively stable flow rate range after flowing out of section three 743, thereby ensuring the continuous filtration effect of the filter barrel 1.

[0059] As an embodiment of the present invention, refer to Figure 5 and Figure 6 The diverter 75 is arranged in a trumpet shape and has a plurality of guide plates 751 arranged in a circular array on the outer wall, and a retaining edge 7511 is arranged at the edge of each guide plate 751; the surface of the diverter 75 has a plurality of groups of water outlet holes 752 arranged in a circular array, and the distance between the water outlet hole 752 and the axis of the guide member 74 is proportional to the aperture of the water outlet hole 752.

[0060] Under the above-mentioned setting conditions, when the water flows from the lower end of section three 743 to the surface of the diverter 75, it will be blocked by the retaining edge 7511 and impact the guide plate 751, thereby forming a vortex effect on the surface of the diverter 75 and driving the diverter 75 to rotate with the connecting rod 7432 as the rotation axis, and the water flowing through the surface of the diverter 75 will partially flow out from the corresponding water outlet 752, thereby increasing the partial range of the water flow on the surface of the filter element in the filter barrel 1, avoiding uneven water flow distribution and causing local flow rate to be too fast or too slow, and further ensuring the filtering effect of the filter barrel 1.

[0061] A control method applicable to the water flow rate control device of the above-mentioned filtering equipment comprises the following steps:

[0062] S1. Start the motor 51, which drives the screw 53 to rotate and drives the water inlet pipe 4 to move back and forth horizontally above the filter tank 3;

[0063] S2, the second screw rod 54 rotates synchronously with the first screw rod 53 under the action of the synchronous belt 56 and the two synchronous wheels 55 and intermittently adjusts the positions of the two filter plates 62, so that impurities on the surface of one filter plate 62 can be automatically cleaned while the other filter plate 62 is filtering;

[0064] S3, start the water pump 71, the water pump 71 pumps the water in the water tank 2 into the filter barrel 1 and assists in driving the screw rod 2 54 to rotate;

[0065] S4, before the water flows into the filter barrel 1, the plug 7433 and the spring 7434 adjust the flow rate of the water through pressure difference and elastic deformation;

[0066] S5. After the water flows into the filter barrel 1, the diverter 75 is driven to rotate and expand the water flow distribution range.

[0067] Working principle:

[0068] The water is pumped into the filter tank 3 through the water inlet pipe 4, and the motor 51 and the water pump 71 are started. The output end of the motor 51 drives the screw rod 1 53 to rotate. When the screw rod 1 53 rotates, it drives the screw rod 2 54 to rotate synchronously under the action of the synchronous belt 56 and the two synchronous wheels 55, and respectively drives the slider 57 and the movable plate 58 to reciprocate in the horizontal direction; Figure 2 and Figure 7 When the movable plate 58 moves from one end position of the filter tank 3 to the middle position, due to the magnetic attraction between the movable plate 58 and the corresponding magnetic block 65, the magnetic block 65 will move synchronously with the movable plate 58 and drive the guide plate 64 and the mounting plate 61 connected thereto to move while moving. Since the mounting plate 61 and the filter plate 62 are hinged, the filter plate 62 will be blocked by the edge of the water tank 2 during the movement of the mounting plate 61 to the middle position of the filter tank 3 and will be folded upward with the hinge as the rotation axis. When the slider 57 moves to the middle position of the filter tank 3, the guide plate 64 will be blocked by the corresponding guide groove 63 and cannot move further. At this time, the filter plate 62 moves to the bottom of the corresponding water leakage port 32; refer to FIG. Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 When the slider 57 moves from the middle position of the filter tank 3 to the other end under the action of the screw rod 53, the movable plate 58 will approach another magnetic block 65 and fit with it, so that during the continuous movement of the movable plate 58, the magnetic block 65 is pushed to drive the corresponding guide plate 64, the mounting plate 61 and the filter plate 62 to move toward the end position of the filter tank 3 in sequence, until the filter plate 62 is separated from the water tank 2 and then folds downward under the action of its own gravity with the hinge with the corresponding mounting plate 61 as the rotation axis. During the folding process, impurities on the surface of the filter plate 62 automatically fall into the inside of the corresponding receiving box 66, thereby ensuring the normal filtering effect of the filter plate 62 in the future.

[0069] When the water pump 71 is working, the water in the water tank 2 is transported to the inside of the hollow column 72 through the guide pipe 73 and impacts the impeller 721. Under the action of the impact force of the water flow, the auxiliary screw 2 54 rotates, reducing the transmission resistance between the two synchronous wheels 55. The water entering the hollow column 72 is decelerated under the action of the segment 1 741 and enters the segment 2 742 and finally flows into the segment 3 743. When the impurities in the water tank 2 cause the water flow rate pumped by the water pump 71 to increase, the water flow in the segment 3 743 will squeeze the plug 7433 and compress the spring 7434, thereby increasing the gap between the plug 7433 and the inner wall of the segment 3 743, thereby achieving the effect of reducing the water flow rate; the impurities in the water tank 2 cause the water flow rate pumped by the water pump 71 to increase When decreasing, the spring 7434 drives the plug 7433 to reset through its own elastic force, thereby reducing the gap between the plug 7433 and the inner wall of the section three 743, thereby increasing the water flow rate, so that the water flow rate entering the filter barrel 1 is maintained within a stable range. After flowing from the section three 743 to the surface of the diverter 75, the water flow will flow downward along the surface of the diverter 75, and under the action of the guide plate 751 and the retaining edge 7511, the diverter 75 is driven to rotate and form a vortex effect. At the same time, part of the water flow will flow out from the corresponding water outlet 752, thereby increasing the water flow distribution range, avoiding the situation where the water flow rate of the local water flow is too fast or too slow due to uneven water distribution, thereby ensuring the filtering effect of the filter barrel 1.
