Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to an integrated filter housing that facilitates welding of filter elements. Background Technology

[0002] In the manufacturing process of integrated filters, the integrated filter housing is its core component, and the welding and installation quality of the housing and filter element in the integrated filter housing has a crucial impact on the performance of the integrated filter.

[0003] Currently, integrated filter housings are typically cylindrical, posing significant challenges during filter element assembly and welding. Because the inner diameter of the housing is larger than the outer diameter of the filter element, ensuring coaxiality between the filter element and the housing is crucial during welding. However, existing technologies lack effective auxiliary measures to guarantee this coaxiality during the welding process. This often leads to inaccurate welding during actual operations. Such inaccurate welding can affect the integrity of the filter element weld, causing bypassing between the upstream and downstream sides and reducing filtration efficiency. Furthermore, long-term use may result in reduced weld strength due to improper welding positions, potentially damaging the filter element or housing, increasing maintenance costs and equipment failure rates, and causing inconvenience and financial losses for users. Utility Model Content

[0004] The purpose of this invention is to provide an integrated filter housing that facilitates the welding of filter elements, thereby solving the problems existing in the prior art, facilitating the welding of filter elements, and improving the installation efficiency of filter elements.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides an integrated filter housing for easy welding of filter elements, including a housing body and multiple connecting plates. One end of each connecting plate is fixed to the inner wall of the housing body, and the other end is used for welding to the filter element. The housing body is cylindrical. All the connecting plates are distributed circumferentially along the housing body.

[0007] Preferably, the length direction of the connecting plate is parallel to the axial direction of the outer shell body, the width direction of the connecting plate is the radial direction of the outer shell body, and the thickness direction of the connecting plate is tangent to the circumferential direction of the outer shell body.

[0008] Preferably, the connecting plate is made of a weldable polymer material.

[0009] Preferably, all of the connecting plates have the same width.

[0010] Preferably, the width of the connecting plate is half the difference between the inner diameter of the outer shell body and the outer diameter of the filter element.

[0011] Preferably, all of the connecting plates are evenly distributed along the circumference of the outer shell body.

[0012] Preferably, the end of the connecting plate closest to the outer casing body is welded to the outer casing body.

[0013] Preferably, all of the connecting plates are integrally formed with the outer shell body.

[0014] Preferably, the length of the connecting plate is less than the axial dimension of the outer casing body.

[0015] Preferably, there are 3, 4, 6, 8, 10 or 12 connecting plates.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] This utility model features an integrated filter housing that facilitates the welding of filter elements. By setting a connecting plate on the inner wall of the housing body, the connecting plate can play a supporting and auxiliary positioning role during filter element installation, thereby improving the installation efficiency of the filter element.

[0018] Furthermore, the length direction of the connecting plate is parallel to the axial direction of the outer shell, enabling the connecting plate to provide stable support for the filter element along the axial direction of the outer shell. Since the width direction of the connecting plate is radial to the outer shell, and one end is connected to the inner wall of the outer shell while the other end is used to connect to the filter element, this provides precise positioning of the filter element in the radial direction within the outer shell. The thickness direction of the connecting plate is tangent to the circumferential direction of the outer shell, which allows the connecting plate to better withstand the circumferential forces generated by the filter element.

[0019] Furthermore, when the end of the connecting plate near the outer shell is welded to the outer shell, a strong connection structure can be formed. Compared with other connection methods (such as bolted connections, which may loosen due to vibration), welding can ensure that the connecting plate and the outer shell are tightly connected. During the long-term operation of the integrated filter, even if it is subjected to external forces such as fluid impact or equipment vibration, the connecting plate is not easy to fall off the outer shell.

[0020] Furthermore, when the connecting plate and the outer shell are integrally molded, there are no weak points in their connection. Compared to welding or bolting, the integrally molded structure can better withstand external forces. The integral molding technology allows for precise control of the position and shape of the connecting plate within the outer shell during manufacturing. During mold design and manufacturing, it ensures that the connecting plate is molded according to predetermined circumferential distribution, axial dimensions, and radial dimensions. This provides highly precise positioning for filter element installation, ensuring coaxiality between the filter element and the shell, thereby improving the quality and efficiency of welded filter elements. The integral molding process reduces the steps involved in connecting the connecting plate and the outer shell in the production process, such as welding or assembly. This not only improves production efficiency but also reduces costs associated with these processes, including labor costs, equipment costs, and time costs. Simultaneously, reducing the number of connection steps reduces potential quality problems during the connection process, further lowering production costs. Attached Figure Description

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The purpose of this invention is to provide an integrated filter housing that facilitates the welding of filter elements, thereby solving the problems existing in the prior art, facilitating the welding of filter elements, and improving the installation efficiency of filter elements.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 2 As shown, this embodiment provides an integrated filter housing for easy welding of filter element 3, including housing body 1 and 6 connecting plates 2. One end of each connecting plate 2 is fixed to the inner wall of housing body 1, and the other end is used for welding to filter element 3. Housing body 1 is cylindrical. All connecting plates 2 are evenly distributed along the circumference of housing body 1.

[0029] The connecting plate 2 can support the filter element 3 and assist in positioning it during installation, thereby improving the installation efficiency of the filter element 3.

[0030] In the optional embodiments of this example, a preferred arrangement is that the length direction of the connecting plate 2 is parallel to the axial direction of the outer shell body 1, the width direction of the connecting plate 2 is radial to the outer shell body 1, and the thickness direction of the connecting plate 2 is tangent to the circumferential direction of the outer shell body 1. The parallelism of the length direction of the connecting plate 2 to the axial direction of the outer shell body 1 allows the connecting plate 2 to provide stable support for the filter element 3 along the axial direction of the outer shell. Since the width direction of the connecting plate 2 is radial to the outer shell body 1, and one end is connected to the inner wall of the outer shell body 1 while the other end is used to connect to the filter element 3, this provides precise positioning of the filter element 3 in the radial direction within the outer shell. The tangency of the thickness direction of the connecting plate 2 to the circumferential direction of the outer shell body 1 allows the connecting plate 2 to better withstand the circumferential forces generated by the filter element 3.

[0031] In this embodiment, the connecting plate 2 is made of a weldable polymer material, such as polypropylene (PP), soluble polytetrafluoroethylene (PFA), or high-density polyethylene (HDPE).

[0032] In this embodiment, all connecting plates 2 have the same width, and the width of the connecting plate 2 is half the difference between the inner diameter of the outer shell body 1 and the outer diameter of the filter element 3, to ensure the coaxiality of the filter element 3 and the outer shell body 1.

[0033] This embodiment provides two connection schemes between the connecting plate 2 and the outer shell 1:

[0034] The first method involves welding the end of the connecting plate 2 closest to the outer shell 1 to the outer shell 1. When the end of the connecting plate 2 closest to the outer shell 1 is welded to the outer shell 1, a strong connection structure is formed. Compared with other connection methods (such as bolted connections, which may loosen due to vibration), welding can ensure that the connecting plate 2 and the outer shell 1 are tightly connected. During the long-term operation of the integrated filter, even if subjected to external forces such as fluid impact or equipment vibration, the connecting plate 2 is not easy to fall off the outer shell 1.

[0035] The second method involves integrally molding the connecting plate 2 with the outer shell body 1. When the connecting plate 2 and the outer shell body 1 are integrally molded, there are no weak points in their connection. Compared to welding or bolting, the integrally molded structure can better withstand external forces. The integral molding technology allows for precise control of the position and shape of the connecting plate 2 within the outer shell body during manufacturing. During mold design and manufacturing, it ensures that the connecting plate 2 is molded according to predetermined circumferential distribution, axial dimensions, and radial dimensions. This provides highly precise positioning for the filter element 3 installation, ensuring the coaxiality of the filter element 3 and the outer shell, thereby improving the quality and efficiency of welding the filter element 3. The integral molding process reduces the steps involved in connecting the connecting plate 2 and the outer shell body 1 in the production process, such as welding or assembly. This not only improves production efficiency but also reduces costs associated with these processes, including labor costs, equipment costs, and time costs. Furthermore, reducing the number of connection steps reduces potential quality problems during the connection process, further lowering production costs.

[0036] Since making all connecting plates 2 integrally molded with the outer shell body 1 can achieve better results, such as improving production efficiency and structural strength, it is preferable to make all connecting plates 2 integrally molded with the outer shell body 1 in practical applications.

[0037] In the optional embodiments of this example, it is preferable that the length of the connecting plate 2 is less than the axial dimension of the housing body 1. When the length of the connecting plate 2 is less than the axial dimension of the housing body 1, the operator has more operating space when installing the filter element 3. The filter element 3 can be more easily inserted into the housing from the axial opening of the housing, avoiding the obstruction that may be caused by an excessively long connecting plate 2. For example, in actual operation, the operator can more easily move the filter element 3 along the axial direction of the housing and align it with the connecting plate 2, without difficulty in placing the filter element 3 because the connecting plate 2 occupies the entire axial length. The shorter connecting plate 2 also provides convenience when the filter element 3 needs maintenance, replacement, or inspection. Maintenance personnel can more easily access the filter element 3 and remove it from the housing. If the connecting plate 2 is too long, it may complicate the disassembly and reinstallation process of the filter element 3, while the shorter connecting plate 2 can effectively avoid this situation, thereby saving maintenance time and effort.

[0038] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
