Description

Technical Field

[0001] This utility model belongs to the field of filter element related technology, and in particular relates to a reinforced structure for powder filter elements. Background Technology

[0002] Powder filter elements are filtration components, typically made of metal powder or other materials. They are widely used in industries such as petrochemicals, chemicals, fine chemicals, coal chemicals, food and beverage, nuclear power, shipbuilding, and automobile manufacturing. Applications include catalyst filtration, liquid and gas filtration, mother liquor recovery filtration in PTA production, filtration in food and beverages, flame arrest and explosion protection, balanced damping airflow, sensor probe protection, pneumatic equipment filtration and noise reduction, fly ash treatment, gas homogenization in the powder industry, and pneumatic conveying. However, they still have the following drawbacks in practical use:

[0003] When powdered filter cartridges are transported to the user end, they are packaged in boxes. However, due to factors such as compression, the filter cartridges may deform due to bending forces, affecting the position of the holes in the installation structure, and the filter cartridges are prone to breakage.

[0004] Secondly, during use, the flow of fluid generates shear force. When the fluid flows along the axial or radial direction of the filter element, the shear force generated can easily cause the filter element structure to delaminate or break, which can easily damage the filter element and affect its durability. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforced structure for powder filter elements. By setting up an installation sleeve, a filter element body, a reinforcing frame, and a reinforcing plate, it solves the problem that powder filter elements are easily deformed by bending forces, and that fluid shear forces transmitted to the filter element can easily cause damage to the filter element.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a reinforced structure for a powder filter element, comprising a mounting sleeve, a filter element body, a reinforcing frame, and a reinforcing plate. An inner fixing ring is fixed to the arc surface of the inner wall of the mounting sleeve. A filling sleeve is fixed inside the inner fixing ring. A sealing ring is fixed to the inner wall of the filling sleeve. The filter element body is fixedly connected to the mounting sleeve inside the sealing ring. A reinforcing plate is fixed in a circular array at the top of the filter element body. A rib is fixed to the top of the reinforcing plate along a center line parallel to its long side. A reinforcing frame is fixed inside the mounting sleeve at the bottom of the filter element body. During operation, the filter element body is fixed within the mounting sleeve, and the filter element body filters the fluid passing through the mounting sleeve. The reinforcing frame increases the shear strength of the filter element body and, through the mounting sleeve, increases the shear strength on the outer side of the filter element body. The reinforcing plate connects the rib to the filter element body and, during operation, increases the bending strength of the filter element body.

[0008] Furthermore, a mounting ring is fixed to the periphery of the mounting sleeve, and the top end of the mounting ring is flush with the top end of the mounting sleeve. The mounting ring on the mounting sleeve provides the mounting function for the mounting sleeve.

[0009] Furthermore, a connecting disc is fixed at the center of the top of the filter element body, and a cone is fixed at the center of the top of the connecting disc, with the connecting disc on the filter element body connecting to the cone.

[0010] Furthermore, the reinforcing frame is fixed inside the mounting sleeve below the filter element body, the end of the reinforcing plate near the center of the filter element body is fixed to the periphery of the connecting disc, and the end away from the center of the filter element body is fixed inside the mounting sleeve above the filter element body. The end of the rib plate near the center of the filter element body is fixed to the periphery of the cone head, increasing the connection strength between the rib plate and the filter element body.

[0011] Furthermore, the reinforcing frame includes a reinforcing ring, a central hole, and a connecting rod. Several concentric reinforcing rings are fixed on the bottom surface of the filter element body. Adjacent reinforcing rings are connected in a ring array to fix the connecting rods. The outermost reinforcing ring and the mounting sleeve are connected in a ring array to fix the connecting rods. The combination of reinforcing rings and connecting rods increases the shear strength of the filter element body.

[0012] Furthermore, each of the ribs is fixed with side plates at equal intervals on both sides, and the bottom of the side plates is fixed to the top of the reinforcing plate below the corresponding rib, thereby increasing the bending strength of the rib body.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of powder filter elements being easily deformed by bending forces by setting up an installation sleeve, filter element body, reinforcing frame and reinforcing plate. When the filter element body is transported or used, when the filter element body is squeezed, the connecting rod between the reinforcing rings first prevents the filter element from bending. The ribs are arranged vertically along the center line of the long side of the reinforcing plate to form a cross support structure, which significantly improves the bending stiffness, prevents the filter element body from bending in all directions, increases the strength of the filter element, and makes the filter element have good bending strength.

[0015] This invention solves the problem of filter element damage caused by fluid shear force transmission by setting up an installation sleeve, filter element body, and reinforcing frame. During the transportation and use of the filter element body, the installation sleeve first realizes the edge shear force resistance function of the filter element body, and the reinforcing ring increases the shear force resistance function of the filter element body inside the installation sleeve. Furthermore, during operation, the connecting rod between the concentric reinforcing rings further increases the shear force resistance function of the two adjacent reinforcing rings, thereby increasing the shear strength of the filter element.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0026] Please see Figure 1-5This utility model is a powder filter element reinforcement structure, including an mounting sleeve 1, a filter element body 2, a reinforcing frame 3, and a reinforcing plate 4. An inner fixing ring 104 is fixed on the arc surface of the inner wall of the mounting sleeve 1. The mounting sleeve 1 installs and fixes the filter element body 2 in it. The inner fixing ring 104 fixes the filling sleeve 103 on its inner side. The filling sleeve 103 is fixed on the inner side of the inner fixing ring 104. A sealing ring 102 is fixed on the inner wall of the filling sleeve 103. The filling sleeve 103 fills the gap between the sealing ring 102 and the inner fixing ring 104 to ensure sealing, so that the sealing ring 102 abuts against the inner fixing ring 4. The filter element body 2 is fixedly connected to the mounting sleeve 1 inside the sealing ring 102 on the side of the filter element body 2. The filter element body 2 filters the fluid passing through the mounting sleeve 1. The top of the filter element body 2 is fixed with a reinforcing plate 4 in a ring array. The reinforcing plate 4 increases the bending resistance of the filter element body 2. The top of the reinforcing plate 4 is fixed with a rib plate 401 along the center line parallel to the long side. The rib plate 401 on the reinforcing plate 4 further increases the bending resistance of the filter element body 2. The mounting sleeve 1 at the bottom of the filter element body 2 is fixed with a reinforcing frame 3. The reinforcing frame 3 increases the shear resistance of the filter element body 2.

[0027] Specifically, a mounting ring 101 is fixed around the periphery of the mounting sleeve 1. The top end of the mounting ring 101 is flush with the top end of the mounting sleeve 1. The mounting ring 101 on the mounting sleeve 1 serves to mount the mounting sleeve 1 to the external mounting structure.

[0028] Furthermore, a connecting disc 201 is fixed at the center of the top of the filter element body 2, and a cone 202 is fixed at the center of the top of the connecting disc 201. The connecting disc 201 on the filter element body 2 is connected to the cone 202, and the cone 202 is connected to the rib plate 401 to increase the connection strength between the rib plates 401.

[0029] Furthermore, the reinforcing frame 3 is fixed inside the mounting sleeve 1 below the filter element body 2 to provide shear protection for the entire filter element body 2. The end of the reinforcing plate 4 near the center of the filter element body 2 is fixed to the periphery of the connecting plate 201, and the end away from the center of the filter element body 2 is fixed inside the mounting sleeve 1 above the filter element body 2. The end of the rib plate 401 near the center of the filter element body 2 is fixed to the periphery of the cone head 202 to provide bending protection for the entire filter element body 2.

[0030] Furthermore, the reinforcing frame 3 includes a reinforcing ring 301, a central hole 302, and a connecting rod 303. Several concentric reinforcing rings 301 are fixed on the bottom surface of the filter element body 2. The connecting rods 303 are fixed together in a ring array between adjacent reinforcing rings 301. The outermost reinforcing ring 301 and the mounting sleeve 1 are also fixed together in a ring array. When the reinforcing frame 3 is in operation, the reinforcing ring 301 is fixed to the bottom end of the filter element body 2, and adjacent concentric reinforcing rings 301 are fixed together by the connecting rods 303, which increases the shear strength of the filter element body 2. The central hole 302 on the reinforcing ring is used to allow the fluid filtered by the filter element body 2 to pass through, which reduces the impact on the filtration efficiency.

[0031] The operation process of this embodiment is as follows: During operation, the mounting sleeve 1 is installed, aligned with the installation structure of the filter equipment, and the bolts or screws for installation are inserted into the mounting ring 101 and then screwed into the filter equipment to install the mounting sleeve 1 and the filter element body 2. During the transportation and use of the filter element body 2, the mounting sleeve 1 first realizes the edge shear resistance function of the filter element body 2, and the reinforcing ring 301 increases the shear resistance function of the filter element body 2 inside the mounting sleeve 1. During operation, the connecting rod 303 between the concentric reinforcing rings 301 further increases the shear resistance function of the two adjacent reinforcing rings 301, thereby increasing the strength of the filter element. Specific Implementation

[0032] Please see Figure 1-6 Based on the first specific embodiment, each rib 401 has a side plate 402 fixed at equal intervals on both sides. The bottom of the side plate 402 is fixed to the top of the reinforcing plate 4 below the corresponding rib 401. During operation, the side plate 402 on the rib 401 is connected to the reinforcing plate 4, increasing the connection strength between the rib 401 and the reinforcing plate 4.

[0033] The operation process of this embodiment is as follows: When the filter element body 2 is being transported or used, when the filter element body 2 is being squeezed, the connecting rod 303 between the reinforcing rings 301 first prevents the filter element from bending, and the ribs 401 on the reinforcing plate 4 further increase the bending resistance, prevent the filter element body 2 from bending in all directions, and increase the strength of the filter element.
