[0021] Please refer to Figures 1 to 3 , in which Figure 1 is a schematic diagram of the overall structure of the large-flow filter element, Figure 2 is a front sectional view of the sleeve, Figure 3It is a structural schematic diagram of a flow splitting device. The present utility model provides a large-flow filter element, which includes a sleeve 101, a water inlet pipe 102, an end cover 103, a discharge pipe 104 and a flow splitting device.

During long-term use, the flow rate of the filter element will become smaller and uneven, affecting the service life. It can be understood that the foregoing solution can be used to enable the filter element to avoid direct impact of the water flow on the filter element when the water flow enters the filter element through the sleeve 101 during use, thereby reducing the impact on the filter element and improving the service life of the filter element. It can also be used to split the water flow entering the sleeve 101 multiple times, greatly improving the protection effect on the filter element.

[0022] For this specific embodiment, the water inlet pipe 102 is fixedly connected to the sleeve 101 and is located on one side of the sleeve 101. The end cap 103 is threadedly connected to the sleeve 101 and is located on one side of the sleeve 101. The discharge pipe 104 is fixedly connected to the end cap 103 and is located on one side of the end cap 103. A filter element assembly is provided inside the sleeve 101. The filter element assembly includes a top plate and a bottom plate. A folded filter membrane is fixedly connected between the top plate and the bottom plate. A through hole communicating with the inside of the filter membrane is formed in the top of the top plate. An annular sealing groove is formed on the inner surface of the through hole. Four positioning rods are fixedly connected to the top of the top plate. A filtering assembly is provided inside the filter element assembly. The filtering assembly includes a filtering cylinder inserted into the filter membrane. A positioning plate is fixedly connected to the outer surface of the top end of the filtering cylinder. A positioning hole for inserting the positioning rod is formed in the positioning plate. The bottom of the sleeve 101 is threadedly connected to the end cap 103. The discharge pipe 104 is fixedly connected to the inside of the end cap 103. The inner diameter of the discharge pipe 104 is equal to the outer diameter of the filtering cylinder. The water inlet pipe 102 is fixedly connected to the top of the sleeve 101. The water inlet pipe 102 communicates with the inside of the sleeve 101. Through the setting of the filter element assembly, the liquid can be preliminarily filtered. Moreover, through the setting of the filtering assembly, the filtering of the liquid can be further enhanced, the filtering effect can be improved, and the filtering work of large liquid flow can be satisfied. The impact of large liquid flow can be effectively avoided, the loosening of the filter element can be caused, and the subsequent filtering work can be affected. Moreover, through the clamping connection of the filtering cylinder and the filter element assembly by using the positioning plate, the stability and positioning of the filter element are effectively improved, the impact resistance function of the filter element is further improved, and it has a good disassembly and assembly function, which is convenient for the staff to clean or replace the filter element. The above are all prior arts.

[0023] Among them, the mounting ring 105 is fixedly connected to the sleeve 101 and is located on one side of the sleeve 101. The support rod 106 is fixedly connected to the mounting ring 105 and is located on one side of the mounting ring 105. The baffle 107 is fixedly connected to the support rod 106 and is located on one side of the support rod 106. The dispersion assembly is arranged on the baffle 107, and the drainage assembly is arranged on the baffle 107. The mounting ring 105 is fixed at the top end of the inner cavity of the sleeve 101. The mounting ring 105 is in a circular ring shape. The number of the support rods 106 is four, and the four support rods 106 are arrayed on the lower surface of the mounting ring 105. The cross-section of the baffle 107 is circular, and the baffle 107 is welded to the bottom end of the support rod 106. The baffle 107, the support rod 106 and the mounting ring 105 enclose a cylindrical shape. The dispersion assembly is arranged on the upper surface of the baffle 107. After the water flow enters the inside of the sleeve 101 through the water inlet pipe 102, the water flow first contacts the dispersion assembly, so that the dispersion assembly disperses the water flow, and then the water flow flows out towards the inside of the sleeve 101 between the plurality of support rods 106, so that the water flow is dispersed and then enters the filter element. The drainage assembly is arranged at the center of the upper surface of the baffle 107. The arrangement of the drainage assembly enables the water flow entering the sleeve 101 to be drained, so that the water flow first contacts the drainage assembly, then contacts the dispersion assembly, and finally enters the filter element, thereby reducing the impact on the filter element. During the use of the filter element, when the water flow enters the filter element through the sleeve 101, the water flow first enters the sleeve 101 from the water inlet pipe 102, and then the drainage assembly buffers the water flow by drainage. Then the water flow contacts the dispersion assembly, so that the water flow spreads out and enters the inside of the sleeve 101 between the plurality of support rods 106, and then enters the filter element, thereby being able to avoid the water flow directly impacting the filter element, reducing the impact on the filter element, and prolonging the service life of the filter element.

[0024] Secondly, the fixing plate 108 is fixedly connected to the baffle 107 and is located on one side of the baffle 107; the rotating ball 109 is rotatably connected to the fixing plate 108 and is located on one side of the fixing plate 108; the fan blade 110 is fixedly connected to the rotating ball 109 and is located on one side of the rotating ball 109. The fixing plate 108 is welded to the center of the upper surface of the baffle 107. The cross-section of the fixing plate 108 is circular, and the diameter of the fixing plate 108 is smaller than the diameter of the baffle 107. The diameter of the fixing plate 108 is adapted to the inner diameter of the water inlet pipe 102. The circumferential surface of the fixing plate 108 is provided with rotating grooves in an array. The number of the rotating balls 109 corresponds to the number of the rotating grooves. The rotating balls 109 are arranged in the rotating grooves one by one, and three-quarters of the volume of the rotating ball 109 is located in the rotating groove, so that the rotating ball 109 can rotate on the circumferential surface of the fixing plate 108. A fan blade 110 is welded to each of the mounting balls. The fan blade 110 has a certain curvature. The fan blade 110 can rotate on the circumferential surface of the fixing plate 108 under the action of the rotating ball 109. After the water flow enters the sleeve 101, it horizontally impacts the fixing plate 108 and then contacts the fan blade 110. Under the impact of the water flow, the fan blade 110 swings on the circumferential surface of the fixing plate 108 through the rotating ball 109, thereby buffering the impact caused by the water flow. The water flow after the impact is dispersed enters the sleeve 101 through the gap between the baffle 107 and the sleeve 101, and then enters the filter element, so as to avoid the water flow directly impacting the filter element and play a protective role on the filter element.

[0025] Meanwhile, the first cylinder 111 is fixedly connected to the fixing plate 108 and is located on one side of the fixing plate 108; the first cone 112 is fixedly connected to the first cylinder 111 and is located on one side of the first cylinder 111; the auxiliary member is arranged on the fixing plate 108. The first cylinder 111 is welded to the center of the upper surface of the fixing plate 108. The first cone 112 is in a conical shape. The circular surface of the first cone 112 is welded to the top end of the first cylinder 111. The diameter of the first cone 112 is larger than the diameter of the first cylinder 111. The tip of the first cone 112 faces upward. After the water flow enters the sleeve 101 through the water inlet pipe 102, the water flow naturally descends and first contacts the first cone 112. The first cone 112 diverts the water flow, so that the water flow continues to descend to the fan blade 110. The swing of the fan blade 110 buffers the water flow, thereby avoiding the water flow directly impacting the filter element and playing a protective role on the filter element.

[0026] When using a large-flow filter element of this embodiment, during the use of the filter element, when water flows through the sleeve 101 into the filter element, the water first enters the sleeve 101 from the water inlet pipe 102, and then contacts the first cone 112, so that the first cone 112 diverts the water flow. The diverted water flow continues to descend to the fan blade 110, so that the fan blade 110 rotates on the circumferential surface of the fixed plate 108 through the rotating ball 109 under the impact of the water flow, thereby buffering the water flow, so that the water flow spreads out and enters the inside of the sleeve 101 between the plurality of support rods 106, and then enters the filter element, which can avoid the direct impact of the water flow on the filter element, reduce the impact on the filter element, and improve the service life of the filter element.

[0027] The second embodiment of this application is as follows:

[0028] On the basis of the first embodiment, please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the auxiliary component of the second embodiment. The auxiliary component of this embodiment includes a second cylinder 201 and a second cone 202.

[0029] For this specific embodiment, the second cylinder 201 is fixedly connected to the fixed plate 108 and is located on one side of the fixed plate 108; the second cone 202 is fixedly connected to the second cylinder 201 and is located on one side of the second cylinder 201. The second cylinders 201 are arranged in an array on the upper surface of the fixed plate 108. The second cylinders 201 are located between the first cylinder 111 and the fan blade 110. The plurality of second cylinders 201 are distributed around the first cylinder 111. The height of the second cylinder 201 is much lower than the height of the first cylinder 111. The second cone 202 is welded to the second cylinder 201. The plurality of second cones 202 are located below the first cone 112 and are circularly distributed below the first cone 112, so that after the water flow is diverted by the first cone 112, the diverted water flow naturally descends and contacts the second cone 202, and then the second cone 202 performs a second diversion, thereby being able to greatly reduce the impact force generated when the water flow enters the sleeve 101, so that when the subsequent water flow enters the filter element, it buffers the filter element.

[0030] When using a large-flow filter element of this embodiment, after the water flow is diverted by the first cone 112, the diverted water flow naturally descends and contacts the second cone 202, and then the second cone 202 performs a second diversion, thereby being able to greatly reduce the impact force generated when the water flow enters the sleeve 101, so that when the subsequent water flow enters the filter element, it buffers the filter element, thereby protecting the filter element.
