Description

Technical Field

[0001] This utility model relates to the field of filter replacement technology, specifically a high-flow filter element that is easy to clean and replace. Background Technology

[0002] In water treatment, industrial filtration, and other fields, filter elements are core components, and their performance directly affects filtration efficiency and ease of use. With the acceleration of industrialization and the increasing demands for environmental protection, the application of high-flow-rate filtration equipment is becoming more and more widespread, placing higher requirements on the flow capacity, ease of cleaning, and replacement efficiency of filter elements.

[0003] In existing technologies, many filter element structures suffer from cumbersome cleaning and replacement processes. For example, the filter element device disclosed in Chinese patent CN221999048U, while possessing certain filtration capabilities, requires the use of tools to disassemble multiple bolts or clips one by one when replacing the built-in filter element. This operation is complex, time-consuming, and fails to meet the needs of efficient maintenance. Over long-term use, impurities easily accumulate on the filter element surface. If it cannot be cleaned or replaced promptly and conveniently, it will not only affect filtration efficiency but may also increase equipment operating resistance and even cause secondary pollution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-flow filter element that is easy to clean and replace.

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

[0006] A high-flow filter element that is easy to clean and replace includes: a hollow cylinder and a fixing rod. A cylinder connector is fixedly installed at the top of the hollow cylinder. A first fastening assembly is installed in the center of the bottom plate of the cylinder connector. A filter element support is installed at the bottom of the hollow cylinder. A base is installed at the bottom of the filter element support. An elastic pad is fixedly installed at the top of the base. The elastic pad is used to place the filter element. The fixing rod passes through a circular through hole in the center of the elastic pad and is fixedly connected to the base. A second fastening assembly is installed at the top of the fixing rod. The fastening assembly is used to separate and install the filter element support from the cylinder connector.

[0007] The hollow cylinder has multiple elliptical through holes on its wall and multiple square through holes on its bottom plate. Both the elliptical and square through holes are used for the flow of filtered water.

[0008] The first set of fastener components includes: a hollow disc and arc-shaped clamps. Multiple arc-shaped clamps are embedded in the hollow disc. Multiple sets of springs are provided on the circular inner wall of the hollow disc. The other end of the springs is fixedly connected to the outer arc surface of the arc-shaped clamps. Multiple arc-shaped clamps can form a ring under the action of the springs.

[0009] The second set of fastener components includes: a cylindrical base and a slider. A guide rod is fixedly installed at the top of the cylindrical base, and a hemispherical block is installed at the top of the guide rod. The slider is installed on the guide rod and moves up and down on the guide rod.

[0010] Preferably, trapezoidal columns are symmetrically arranged at the upper and lower ends of the slider, and a circular groove is provided at the bottom end of the hemispherical block. The circular groove is used to cooperate with the trapezoidal column at the upper end of the slider, and the inner arc surface of the arc-shaped clamping block is set as a downward inclined surface.

[0011] Preferably, when the filter element support is installed and fixed to the cylinder joint, the top part of the elastic pad is embedded in the bottom end of the hollow cylinder.

[0012] Preferably, the inner wall of the cylindrical connector is provided with an internal thread, which is used for threaded connection with the outlet of the filtered water.

[0013] Preferably, a replaceable filter element is fitted onto the fixing rod.

[0014] Compared with the prior art, this utility model provides a high-flow filter element that is easy to clean and replace, and has the following beneficial effects:

[0015] The first set of fastening components adopts a design with a hollow disc embedded with an arc-shaped clamping block and a spring. Multiple arc-shaped clamping blocks can form a ring under the action of the spring. When the hemispherical block of the second set of fastening components moves upward, the spring is compressed. When the arc-shaped clamping block enters the guide rod, the spring is released. At this time, the arc-shaped clamping block and the hemispherical block are locked together, and the filter element bracket and the cylinder connector are installed and fixed.

[0016] When it is necessary to separate the filter element support from the cylinder connector, simply continue to move the hemispherical block upwards. The arc-shaped clamping block passes sequentially through the symmetrical trapezoidal columns at the upper and lower ends of the slider. The spring is first compressed and then released. At this time, the hemispherical block begins to move downwards. The arc-shaped clamping block drives the slider to slide on the guide rod. When the upper trapezoidal column of the slider is embedded in the circular groove, the spring begins to compress. Continue to move the hemispherical block downwards, and the spring goes from compression to release. After the release is complete, the separation of the filter element support from the cylinder connector is easily completed. The whole process requires no tools, only simple pressing of the base of the filter element support, which greatly shortens the filter element replacement time and improves maintenance efficiency.

Detailed Implementation

[0027] 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.

[0028] Reference Figures 1-9 As shown, this embodiment of a high-flow filter element that is easy to clean and replace includes a hollow cylinder 1 and a fixing rod 402. A cylinder connector 2 is fixedly installed at the top of the hollow cylinder 1 by welding. An installation groove is formed in the center of the bottom plate of the cylinder connector 2, and a first fastening assembly 6 is fixedly installed in the installation groove. A filter element support 4 is provided at the bottom of the hollow cylinder 1. A base is bolted to the bottom of the filter element support 4, and an elastic pad 401, made of food-grade silicone, is fixedly installed at the top of the base by adhesive. The elastic pad 401 is used to place the filter element 3. The fixing rod 402 passes through a circular through-hole in the center of the elastic pad 401 and is threaded to the base. A second fastening assembly 5 is provided at the top of the fixing rod 402. The fastening assembly is used to separate and install the filter element support 4 from the cylinder connector 2.

[0029] The hollow cylinder 1 has multiple elliptical through holes 101 on its cylinder wall. The major axis of the elliptical through holes 101 is aligned with the axial direction of the hollow cylinder 1 and is evenly distributed circumferentially. The bottom plate of the cylinder connector 2 has multiple square through holes 202 arranged in a matrix. Both the elliptical through holes 101 and the square through holes 202 are used for the flow of filtered water.

[0030] The first set of fastening components 6 includes a hollow disc and an arc-shaped clamping block 601. Multiple arc-shaped clamping blocks 601 are embedded in the hollow disc. Multiple sets of springs 602 are provided on the circular inner wall of the hollow disc. The other end of the spring 602 is fixedly connected to the outer arc surface of the arc-shaped clamping block 601. Multiple arc-shaped clamping blocks 601 can form a ring under the action of the spring 602.

[0031] The second set of fastener assembly 5 includes a cylindrical base 501 and a slider 502. A guide rod 504 is fixedly mounted on the top of the cylindrical base 501, and a hemispherical block 503 is mounted on the top of the guide rod 504. The slider 502 is mounted on the guide rod 504 and moves up and down on the guide rod 504. Trapezoidal columns are symmetrically arranged at the upper and lower ends of the slider 502. A circular groove is provided at the bottom of the hemispherical block 503, which is used to cooperate with the upper trapezoidal column of the slider 502. The inner arc surface of the arc-shaped clamping block 601 is set as a downward inclined surface with an inclination angle of 45°.

[0032] When the filter element support 4 is installed and fixed to the cylinder connector 2, the top part of the elastic pad 401 is embedded into the bottom end of the hollow cylinder 1 to form a sealing structure. The inner wall of the cylinder connector 2 is provided with an internal thread 201, which is used for threaded connection with the outlet of the filtered water. A replaceable filter element 3 is sleeved on the fixing rod 402.

[0033] In some examples, the top of the elastic pad 401 is provided with an annular protrusion, and the bottom of the hollow cylinder 1 is provided with an annular groove. The annular protrusion and the annular groove cooperate to further enhance the sealing performance and prevent the filtered water from leaking.

[0034] The working principle of this utility model is as follows:

[0035] During installation, lift the base of the filter element bracket 4 upwards so that the second fastening assembly 5 at the top of the fixing rod 402 is aligned with the first fastening assembly 6 in the center of the bottom plate of the cylinder connector 2. At this time, the hemispherical block 503 of the second fastening assembly 5 initially contacts the arc-shaped clamping block 601 of the first fastening assembly 6, and the inner arc surface of the arc-shaped clamping block 601 and the outer arc surface of the hemispherical block 503 form a wedge-shaped guide structure.

[0036] By continuously pressing upwards on the base of the filter element support 4, the hemispherical block 503 slides upwards along the inner arc surface of the arc-shaped clamp 601, forcing the arc-shaped clamp 601 to expand outwards and compress the spring 602. After the hemispherical block 503 passes the arc-shaped clamp 601, the spring 602 releases its elastic force, pushing the arc-shaped clamp 601 to contract inwards, forming a ring clamp on the hemispherical block 503, thus completing the installation and fixation of the filter element support 4 and the cylindrical connector 2.

[0037] When the sealing and positioning filter element bracket 4 is installed in place, the top part of the elastic pad 401 is embedded in the annular groove at the bottom of the hollow cylinder 1, and the elastic deformation of the silicone material forms a seal to prevent filtered water from leaking from the connection.

[0038] The water to be filtered enters from the external interface of the cylinder connector 2, first passing through the square through-hole 202 on the bottom plate, and is evenly distributed into the interior of the hollow cylinder 1. The water flows downward along the outside of the filter element 3 and is discharged through the elliptical through-hole 101 on the wall of the hollow cylinder 1. The filter element 3 is sleeved on the fixing rod 402, and impurities are intercepted on the outside of the filter element. The clean water enters the external pipe through the elliptical through-hole 101, achieving high-flow filtration.

[0039] The elastic pad 401 provides cushioning under the impact of water flow, reducing the vibration of the filter element 3; the threaded connection between the fixing rod 402 and the base and the locking structure of the buckle assembly ensure that the filter element bracket 4 remains stable under high-pressure water flow, avoiding a decrease in filtration efficiency due to shaking.

[0040] During separation, continue pressing upwards on the base of the filter element support 4. As the arc-shaped clamp 601 passes sequentially through the symmetrical trapezoidal columns at the upper and lower ends of the slider 502, the spring 602 is first compressed and then released, causing the base of the filter element support 4 to move downwards. The hemispherical block 503 drives the slider 502 to move upwards along the guide rod 504. When the upper trapezoidal column of the slider 502 is embedded in the circular groove, the lower trapezoidal column of the slider 502 first presses against the inner arc surface of the arc-shaped clamp 601, compressing the spring 602. After the hemispherical block 503 completely disengages from the locking ring of the arc-shaped clamp 601, continue applying force to separate the filter element support 4 from the cylindrical connector 2. The entire process requires no tools, only one-handed pressing, and takes only a few seconds.

[0041] After separation, filter element 3 can be directly removed from the fixing rod 402 for cleaning or replacement. The elastic pad 401 should be cleaned separately to prevent impurities from remaining. After attaching the new filter element to the fixing rod 402, repeat the installation steps to complete the replacement.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
