Description
Technical Field
[0001] This utility model relates to the field of filtration equipment technology, specifically to a filter element replacement device for a horizontal filter. Background Technology
[0002] Large-diameter horizontal metal filter cartridges are widely used in chemical, petroleum, and power industries. They have advantages such as large flow rate, high temperature and high pressure resistance, and long service life. However, due to the large size and heavy weight of the metal filter cartridges and their matching mounting discs, there are significant operational difficulties in actual installation and daily maintenance.
[0003] When replacing filter elements, traditional structural designs require the entire filter to be removed from its original installation location and disassembled and hoisted using large lifting equipment such as overhead cranes in order to remove the old filter element and install the new one. This operation is not only complex and time-consuming, but also places high demands on the on-site lifting equipment. For workshops that lack large lifting equipment or have limited space, filter element replacement is particularly difficult or even impossible, seriously affecting the normal operation and maintenance efficiency of the equipment.
[0004] Therefore, existing technologies need further development. Utility Model Content
[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a filter element replacement device for a horizontal filter to solve the technical problem that filter element replacement is particularly difficult or even impossible to implement in some workshops that lack large lifting equipment or have limited space, which seriously affects the normal operation and maintenance efficiency of the equipment.
[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a filter element replacement device for a horizontal filter is provided, comprising: a filter body, the filter body being mounted on an installation reference, the filter body having a filter chamber and an inlet communicating with the filter chamber, the filter body extending along a first preset direction; a filter element assembly, the filter element assembly being movably disposed within the filter chamber along the extending direction of the filter body, the filter element assembly being used to filter water; and an installation assembly, the installation assembly being movably disposed on the side of the filter body near the inlet, the filter element assembly being movably disposed on the installation assembly, the installation assembly having a driving part and a conveying part, the conveying part being used to convey the filter element assembly to be installed, the driving part being drivenly connected to the conveying part so as to drive the conveying part to move through the driving part.
[0007] Furthermore, the filter body has at least two cover mounting holes on the side near the inlet, with each cover mounting hole spaced apart along the periphery of the filter body; the mounting assembly includes: at least two insert rods, each insert rod corresponding to each cover mounting hole, each insert rod being movably disposed within the corresponding cover mounting hole along the extension direction of the filter body; an arc-shaped mounting plate extending along a preset arc trajectory, the arc-shaped mounting plate being hinged to each insert rod, the arc-shaped mounting plate being oscillating relative to the filter body, and the arc-shaped mounting plate forming a preset angle with the axial direction of the filter body, the preset angle being greater than 90° and less than or equal to 270°; so that the arc-shaped mounting plate, by oscillating relative to the filter body, conveys the filter element assembly to be installed into the filter chamber; wherein, each insert rod and the arc-shaped mounting plate form a conveying section.
[0008] Furthermore, the mounting assembly also includes: a telescopic member, the telescopic end of which extends and retracts in a vertical direction, the telescopic member being located below the arc-shaped mounting plate, the telescopic end of which is connected to the arc-shaped mounting plate so as to drive the arc-shaped mounting plate to rotate by the extension and retraction of the telescopic member, the telescopic member constituting a drive unit.
[0009] Furthermore, the mounting assembly also includes: at least two first guide rails, each extending along the extension direction of the filter body, and the first guide rails being spaced apart within the filter chamber along the periphery of the filter body, with the filter element assembly movably mounted on each first guide rail 10 along the extension direction of the first guide rails; and a second guide rail, extending along a second preset direction, mounted on the top of the arc-shaped mounting plate, with the filter element assembly movably mounted on the second guide rail along the extension direction of the second guide rail, and the second guide rail being used to guide the filter element assembly onto each first guide rail.
[0010] Further, the filter element assembly includes: a filter element extending along the extension direction of the filter body and disposed within the filter chamber; two mounting plates spaced apart along the extension direction of the filter body and movably disposed within the filter chamber along the extension direction of the filter body, the filter element being mounted between the two mounting plates, and the two mounting plates being fixed within the filter chamber by fasteners; at least two sliders spaced apart around the periphery of the mounting plates; each slider corresponding to a first guide rail, and each slider movably disposed on the corresponding first guide rail along the extension direction of the first guide rail.
[0011] Furthermore, the filter element replacement device for the horizontal filter also includes a cover, which is connected to the cover mounting hole on the filter body by bolts, and the cover is used to seal the filter chamber.
[0012] Beneficial effects:
[0013] 1. Through the design of the drive and conveying parts of the installation components, the filter cartridges can be directly slid and installed at the inlet of the filter body, completely avoiding the need to disassemble the filter body or rely on a crane in traditional operations. This is especially suitable for scenarios with limited space or no large lifting equipment.
[0014] 2. The filter body has at least two cover mounting holes that, together with the insertion rod, form an axial positioning mechanism. This, combined with the hinged arc-shaped mounting plate, creates a variable-angle conveying channel. When the preset angle is adjusted to a suitable level, the arc-shaped mounting plate forms a material sliding ramp, allowing the filter element assembly to automatically slide into the filtration chamber under gravity. This structure replaces traditional hoisting operations with a swing-type conveyor, effectively reducing the height requirements for equipment assembly and disassembly. Filter element replacement can be performed in the same location as the equipment, significantly reducing reliance on lifting equipment.
[0015] 3. The first and second guide rails form a spatial cross-guide system. When the second guide rail swings with the arc-shaped mounting plate to the coaxial position with the first guide rail, the ends of the two guide rails form a continuous slide, ensuring that the slider of the filter element assembly can transition without impact. This guide system achieves precise positioning through a mechanical self-centering design, avoiding errors from manual adjustment, and is particularly suitable for the installation and positioning of large filter elements with a diameter exceeding 1.5 meters.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0021] According to an embodiment of this utility model, a filter element replacement device for a horizontal filter is provided. Please refer to [link / reference]. Figures 1 to 2 The system includes: a filter body 1, which is mounted on a mounting base and has a filter chamber 2 and an inlet 3 communicating with the filter chamber 2; the filter body 1 extends along a first preset direction; a filter element assembly 4, which is movably disposed in the filter chamber 2 along the extension direction of the filter body 1 and is used to filter water; and a mounting assembly 5, which is movably disposed on the side of the filter body 1 near the inlet 3 and has the filter element assembly 4 movably disposed on the mounting assembly 5. The mounting assembly 5 has a driving part and a conveying part, the conveying part is used to convey the filter element assembly 4 to be installed, and the driving part is drivenly connected to the conveying part so as to drive the conveying part to move.
[0022] By adopting the above technical solution and through the design of the drive and conveying parts of the mounting component 5, the filter element group 4 can be directly slidably loaded and unloaded at the inlet 3 of the filter body 1, completely avoiding the need to disassemble the filter body 1 or rely on the operation of a crane in traditional operations, which is especially suitable for scenarios with limited space or no large lifting equipment.
[0023] Please refer to Figure 1 and Figure 2 The filter body 1 has at least two cover mounting holes 6 on the side near the inlet 3, and the cover mounting holes 6 are spaced apart along the periphery of the filter body 1. The mounting assembly 5 includes: at least two insert rods 7, each insert rod 7 corresponding to each cover mounting hole 6, and each insert rod 7 is movably disposed in the corresponding cover mounting hole 6 along the extension direction of the filter body 1; an arc-shaped mounting plate 8, which extends along a preset arc trajectory, is hinged to each insert rod 7, and is swayable relative to the filter body 1, forming a preset angle with the axial direction of the filter body 1, the preset angle being greater than 90° and less than or equal to 270°; so that the arc-shaped mounting plate 8 can sway relative to the filter body 1 to transport the filter element assembly 4 to be installed into the filter chamber 2; wherein, each insert rod 7 and the arc-shaped mounting plate 8 form a conveying part.
[0024] By adopting the above technical solution, the filter body 1 has at least two cover mounting holes 6 that, together with the insertion rod 7, form an axial positioning mechanism, which, together with the hinged arc-shaped mounting plate 8, forms a variable-angle conveying channel. When the preset included angle is adjusted to a suitable angle, the arc-shaped mounting plate 8 can form a material sliding slope, allowing the filter element assembly 4 to automatically slide into the filter chamber 2 under the action of gravity. This structure replaces traditional hoisting operations with swing-type conveying, effectively reducing the equipment disassembly and assembly height requirements, allowing filter element replacement operations to be performed in the original position of the equipment, and significantly reducing reliance on lifting equipment.
[0025] Specifically, the filter cartridge 4 to be installed is placed on the arc-shaped mounting plate 8.
[0026] Please refer to Figure 1 and Figure 2 The mounting assembly 5 also includes a telescopic member 9, the telescopic end of which extends and retracts in the vertical direction. The telescopic member 9 is located below the arc-shaped mounting plate 8, and the telescopic end of the telescopic member 9 is connected to the arc-shaped mounting plate 8 so that the arc-shaped mounting plate 8 can be rotated by the extension and retraction of the telescopic member 9. The telescopic member 9 constitutes a driving part.
[0027] By adopting the above technical solution, the telescopic component 9 adopts a vertical lifting drive method, and changes its tilt angle by pushing and pulling the arc-shaped mounting plate 8; the vertical movement trajectory of the telescopic component 9 and the rotation axis of the arc-shaped mounting plate 8 form a lever transmission relationship, which can achieve a large angle adjustment with a small stroke, and complete the precise control of the conveying angle within a limited space.
[0028] Please refer to Figure 2 The mounting assembly 5 further includes: at least two first guide rails 10, each first guide rail 10 extending along the extension direction of the filter body 1, and each first guide rail 10 being disposed at intervals along the periphery of the filter body 1 within the filter chamber 2, the filter element assembly 4 being movably disposed on each first guide rail 10 along the extension direction of the first guide rail 10; and a second guide rail 11, the second guide rail 11 extending along a second preset direction, the second guide rail 11 being mounted on the top of the arc-shaped mounting plate 8, the filter element assembly 4 being movably disposed on the second guide rail 11 along the extension direction of the second guide rail 11, and the second guide rail 11 being used to guide the filter element assembly 4 to each first guide rail 10.
[0029] Furthermore, the second guide rail 11 is coaxially arranged with one of the first guide rails 10.
[0030] By adopting the above technical solution, the first guide rail 10 and the second guide rail 11 form a spatial cross guide system; when the second guide rail 11 swings with the arc-shaped mounting plate 8 to be coaxial with the first guide rail 10, the ends of the two guide rails form a continuous slide, ensuring that the slider 13 of the filter element group 4 can transition without impact; this guide system achieves precise positioning through mechanical self-centering design, avoiding manual adjustment errors, and is particularly suitable for the installation and positioning of large filter elements with a diameter of more than 1.5 meters.
[0031] Please refer to Figure 2The filter element assembly 4 includes: a filter element extending along the extension direction of the filter body 1 and disposed within the filter chamber 2; two mounting plates 12 spaced apart along the extension direction of the filter body 1 and movably disposed within the filter chamber 2, with the filter element mounted between the two mounting plates 12 and the two mounting plates 12 fixed within the filter chamber 2 by fasteners; at least two sliders 13 spaced apart around the periphery of the mounting plates 12; each slider 13 corresponding to a first guide rail 10 and movably disposed on the corresponding first guide rail 10 along the extension direction of the first guide rail 10.
[0032] By adopting the above technical solution, the circumferentially distributed sliders 13 on the mounting plate 12 form a surface contact guide with the first guide rail 10, which has higher load-bearing stability compared with the traditional roller structure. The double mounting plate 12 design forms synchronous guidance at both ends, which can effectively prevent the slender filter element with a length-to-diameter ratio greater than 5:1 from deflecting during movement. The fasteners adopt a quick-release locking mechanism, which can quickly complete the axial fixation of the filter element group 4 after the guide rail system is in place.
[0033] Specifically, fasteners can be connected and fixed using bolts and nuts.
[0034] Please refer to Figure 1 The filter element replacement device for the horizontal filter also includes a cover, which is connected to the cover mounting hole 6 on the filter body 1 by bolts. The cover is used to seal the filter chamber 2.
[0035] By adopting the above technical solution, after the cover is disassembled, the cover mounting hole 6 on the filter body 1 is exposed. By inserting each of the plug rods 7, the positioning of the arc-shaped mounting plate 8 can be completed without additional drilling, which is convenient for assembly and use.

[0037] Close the inlet and outlet valves of the filter to release pressure and empty the medium in filter chamber 2;
[0038] Remove the bolts on the cover mounting hole 6 and remove the original cover;
[0039] The insert rod 7 is fully inserted into the cover mounting hole 6, simultaneously positioning the arc-shaped mounting plate 8;
[0040] When the telescopic component 9 is retracted, it causes the arc-shaped mounting plate 8 to swing upward to a preset angle to form an inclined slide.
[0041] Loosen the quick-release fasteners of the mounting plate 12, and the filter element group 4 slides along the first guide rail 10 to the second guide rail 11 of the arc-shaped mounting plate 8 under the action of gravity, and finally slides out of the filter body 1;
[0042] The telescopic component 9 remains retracted, causing the arc-shaped mounting plate 8 to swing down to an inclined state;
[0043] Move the filter cartridge 4 to be installed onto the second guide rail 11 of the arc-shaped mounting plate 8;
[0044] Extend the telescopic component 9 to drive the arc-shaped mounting plate 8 to swing upward to the preset angle;
[0045] The second guide rail 11 and the first guide rail 10 inside the filter chamber 2 automatically form a continuous slide.
[0046] Release the temporary fixation of filter element assembly 4, and slide the slider 13 of filter element assembly 4 into the first guide rail 10 along the second guide rail 11;
[0047] The two mounting discs move synchronously to ensure that the filter element group 4 is axially aligned.
