Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter elements, specifically a transversely folded high-flow-rate filter element device. Background Technology
[0002] The main functions of security filters include removing tiny particles from fluids, protecting downstream equipment, improving process efficiency and product quality, and providing safety assurance. The filter element of a security filter is used as a filtration element for solid-liquid separation of various suspensions. When in use, the filter element needs to be installed inside the filter, and the liquid to be filtered is supplied into the filter. The liquid to be filtered is filtered through the filter element. Currently, to increase the filtration area and flow rate of the pleated filter element, it can only be achieved by increasing the number of pleats and increasing the pleat height. However, considering the replaceability of the filter element, the diameter of the pleated filter element cannot be increased indiscriminately, otherwise it will not be able to be installed and used in the original filter. Similarly, the size of the filter cannot be increased, as the cost will be too high.
[0003] Therefore, it is necessary to propose a transverse folding high-flow-rate filter cartridge device. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a replaceable, high-flow-rate pleated filter element device suitable for security filters.
[0005] The technical solution of this utility model is a transverse folding high-flow-rate folded filter element device, including a housing, a socket at one end of the housing, an end cap at the other end of the housing, an inlet hole on the inner wall of the housing, and multiple folded filter element assemblies arranged inside the housing, the multiple folded filter element assemblies being disposed between the socket and the end cap;
[0006] The pleated filter assembly includes a main filter layer perpendicular to the housing and an arc-shaped side filter on the sidewall of the main filter layer.
[0007] The folded filter element assembly is a folding unit. Multiple folded filter element assemblies enable the filter element of the security filter to be folded laterally for high flow rate use. Preferably, the number of folds is 100-105, meaning it contains 100-105 folding units.
[0008] According to the present invention, in a transversely folded high-flow-rate filter cartridge device, preferably, the arc-shaped side filter is transversely bent. Transverse bending means that the bending direction is perpendicular to the outer shell.
[0009] Furthermore, the arc-shaped side filter has a first inner filter layer on its inner arc side, the first inner filter layer is bent laterally inward, and a connecting line is provided on the inner side of the first inner filter layer; an arc-shaped side filter is provided on each side of the main filter layer, and a first inner filter layer is provided on the inner arc side of each side, and the connecting line connects the first inner filter layers on both sides.
[0010] On the left and right sides of the main filter layer in the same layer, there is an arc-shaped side filter. The connecting line connects the inward horizontal bend of the first inner filter layer on the left and right sides, which serves as a connection.
[0011] Furthermore, a flow-guiding cotton plate is provided on the inner side of the main filter layer near the top portion of the filter element assembly. The bottom of the flow-guiding cotton plate is bent inward, and the inner wall of the flow-guiding cotton plate is configured as an inner vortex shape. For example... Figure 1 As shown, the portion near the end cap 12 is defined as the top.
[0012] Furthermore, adjacent main filter layers are connected by connecting filter layers, and a second inner filter layer is provided on the inner side of the connecting filter layer.
[0013] Furthermore, the second inner filter layer is bent laterally inward.
[0014] Furthermore, the pore size of the connecting filter layer and the arc-shaped side filter is larger than the pore size of the first inner filter layer and the second inner filter layer. That is, the connecting filter layer and the arc-shaped side filter are coarse filters, while the first inner filter layer and the second inner filter layer are fine filters.
[0015] Preferably, the main filter layer and the arc-shaped side filter can be slidably inserted into the interior of the housing.
[0016] Beneficial effects:
[0017] By setting a pleated filter element assembly on the security filter element, the liquid is coarsely filtered by the horizontally arranged arc-shaped side filter and connecting filter layer, and finely filtered by the first inner filter layer and the second inner filter layer. The pleated filter element assembly is horizontally bent, which not only allows the filter element to be folded, but also increases the filtration flow rate. Attached Figure Description

[0023] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0024] like Figures 1-4 ;
[0025] A transversely folded high-flow-rate filter cartridge device includes a housing 1, which is used to protect and assemble a filter cartridge for a security filter. The bottom of the housing 1 is snapped with a socket 11 for insertion into the interior of the security filter. The top of the housing 1 is snapped with an end cap 12 for closing the top of the housing 1 and positioning the filter cartridge. An inlet hole 13 is provided on the inner wall of the housing 1 to facilitate the entry of liquid from the security filter into the housing 1, and then the liquid is filtered by the folded filter cartridge. A folded filter cartridge assembly 2 is provided inside the housing 1, which enables the filter cartridge for the security filter to be folded laterally for high-flow-rate use.
[0026] Furthermore, the folded filter element assembly 2 includes a main filter layer 21 and an arc-shaped side filter 22. The sidewall of the main filter layer 21 is provided with an arc-shaped side filter 22, which is laterally bent. The main filter layer 21 not only provides support but also filters the liquid. The main filter layer 21 and the arc-shaped side filter 22 are slidably inserted into the interior of the outer shell 1. After unfolding, the arc-shaped side filter 22 bends laterally outward, increasing the lateral filtration flow of the filter element. The water flow will not impact and bend the arc-shaped side filter 22 inward. The inner side of the arc-shaped side filter 22 is provided with a first inner... The filter layer 23, the first inner filter layer 23, is bent laterally inward. Due to the liquid flow filtration, the liquid will impact inward, causing the first inner filter layer 23 to bend laterally inward continuously. The liquid is finely filtered through the first inner filter layer 23, which not only increases the filtration effect but also increases the filtration volume. A connecting line 24 is provided on the inner side of the first inner filter layer 23. The first inner filter layer 23 is connected and pulled inward through the connecting line 24, so that the first inner filter layer 23 can bend inward when bending laterally, and also increases the stability of the installation of the first inner filter layer 23.
[0027] A guide cotton plate 25 is provided on the top inner side of the main filter layer 21. The bottom of the guide cotton plate 25 is bent inward, and the inner wall of the guide cotton plate 25 is set in an inner vortex shape to form a centrifugal vortex. The guide cotton plate 25 guides the filtered liquid inside the main filter layer 21 downward, so that the liquid flows and forms a vortex at the same time, resulting in better downward flow and higher efficiency. The main filter layers 21 are connected by a connecting filter layer 26. The connecting filter layer 26 is not only used to connect the two main filter layers 21, but also to perform coarse filtration of the liquid. When the filter element is bent, the connecting filter layer 26 and the second The inner filter layer 27 can also be bent laterally. A second inner filter layer 27 is provided on the inner side of the connecting filter layer 26. The second inner filter layer 27 is used to perform secondary fine filtration on the liquid filtered by the connecting filter layer 26. The filtered liquid enters the guide cotton plate 25 and flows downward. The second inner filter layer 27 bends laterally inward to increase the filtration flow rate. The connecting filter layer 26 and the arc-shaped side filter 22 are coarse filters. The connecting filter layer 26 and the arc-shaped side filter 22 are made of non-woven fabric. The first inner filter layer 23 and the second inner filter layer 27 are fine filters. The first inner filter layer 23 and the second inner filter layer 27 are made of glass fiber cotton.
[0028] The working principle of this utility model is as follows: An arc-shaped side filter 22 is provided on the side wall of the main filter layer 21. The main filter layer 21 and the arc-shaped side filter 22 are slidably inserted into the interior of the outer shell 1. A first inner filter layer 23 is provided on the inner side of the arc-shaped side filter 22. The first inner filter layer 23 is bent inward laterally. A connecting line 24 is provided on the inner side of the first inner filter layer 23. A guide cotton plate 25 is provided on the top inner side of the main filter layer 21. The bottom of the guide cotton plate 25 is bent inward. The inner wall of the guide cotton plate 25 is set in an inner vortex shape. The main filter layers 21 are connected by a filter... Layer 26 is connected, and a second inner filter layer 27 is provided inside the connecting filter layer 26. The second inner filter layer 27 is bent laterally inward. The connecting filter layer 26 and the arc-shaped side filter 22 are for coarse filtration, while the first inner filter layer 23 and the second inner filter layer 27 are for fine filtration. After the connecting filter layer 26 and the arc-shaped side filter 22 perform coarse filtration of the liquid, the liquid then passes through the first inner filter layer 23 and the second inner filter layer 27 for fine filtration. The arc-shaped side filter 22 is bent laterally, and after unfolding, it bends laterally outward. The arc-shaped side filter 22 is equipped with a filter element. The horizontal filtration flow rate prevents the water flow from impacting and bending the arc-shaped side filter 22 inward. The first inner filter layer 23 bends horizontally inward. Due to the liquid flow filtration, the liquid impacts inward, causing the first inner filter layer 23 to continuously bend horizontally inward. The first inner filter layer 23 performs fine filtration of the liquid, increasing both the filtration effect and the filtration volume. The connecting line 24 connects and pulls the first inner filter layer 23 inward, allowing it to bend inward during horizontal bending and increasing the stability of the first inner filter layer 23 installation. After the liquid enters the main filter layer 21, the liquid forms an internal vortex on the inner wall of the guide cotton plate 25, creating a centrifugal vortex. The guide cotton plate 25 guides the filtered liquid inside the main filter layer 21 downward, creating a vortex while the liquid flows, resulting in better downward flow and higher efficiency. Since the first inner filter layer 23, the second inner filter layer 27, the connecting filter layer 26, and the arc-shaped side filter 22 are all bent horizontally, the filter element can not only be folded but also the filtration flow rate can be increased.
