Description

Technical Field

[0001] This utility model belongs to the field of filter element technology, and in particular relates to an improved structure of a filter foam filter element. Background Technology

[0002] Foam filter cartridges are filter elements made of foam material, possessing numerous excellent properties and a wide range of applications. The following is a detailed analysis of foam filter cartridges:

[0003] I. Material Composition

[0004] Foam filter cartridges are mainly made of special foam materials, such as high-density polyurethane foam. This material has a rich pore structure, which can effectively trap and filter impurity particles in the media.

[0005] II. Working Principle

[0006] The working principle of foam filter cartridges is to use the porous structure of foam material to capture impurity particles in the medium through physical interception. When the medium (such as air, oil, etc.) passes through the filter cartridge, impurities are blocked on the surface or inside of the filter cartridge, thereby purifying the medium.

[0007] III. Performance Characteristics

[0008] High-efficiency filtration: Foam filter cartridges can filter out tiny particles in the media, ensuring the cleanliness of the media.

[0009] High durability: The foam material has good elasticity and wear resistance, which gives the filter element a long service life.

[0010] Easy to replace: Foam filter elements are usually modular in design, making replacement convenient and quick, thus reducing maintenance costs.

[0011] Wide range of applications: Foam filter elements can be used for filtering various media and environments, such as air and oil.

[0012] When using existing foam filter cartridges, the cartridges are relatively soft and prone to deformation during installation. Usually, a frame is installed on the outside of the foam filter cartridge to fix it. However, since foam filter cartridges need to be replaced after long-term use, the replacement is very inconvenient. In addition, the existing foam filter cartridge frames cannot be adapted to different specifications of foam filter cartridges, so their practicality is poor. In view of this, we propose an improved structure for filtering foam filter cartridges. Utility Model Content

[0013] The purpose of this invention is to provide an improved structure for a filter foam cartridge to solve the problems mentioned in the background art.

[0014] In view of this, the present invention provides an improved structure for a filter foam cartridge, comprising:

[0015] An outer protective frame, within which an inner protective frame is provided, and within which a filter element body is fixedly installed;

[0016] Four clamping plates are slidably installed on the inner bottom surface of the outer protective frame, and one side of each clamping plate abuts against the four sides of the inner protective frame.

[0017] Multiple sets of adjustment components are respectively arranged inside the outer protective frame and are used to drive multiple clamping plates to move.

[0018] In the above technical solution, the adjusting component further includes two fixed seats, which are fixedly installed on one side of the clamping plate. Two movable seats are slidably installed on the inner side of the outer protective frame. A connecting rod is rotatably installed in each of the two movable seats. One end of each connecting rod is rotatably installed in the two fixed seats. When the two movable seats move away from each other, the cooperation between the connecting rod and the fixed seats will drive the clamping plate to move away from the inner protective frame. When the clamping plate moves away from the inner protective frame, the restriction on the inner protective frame can be released, and the inner protective frame can be disassembled from the outer protective frame.

[0019] In the above technical solution, the adjustment component further includes a side box, which is fixedly installed on the outer side wall of the outer protective frame. Two racks are slidably installed inside the side box, and a gear is rotatably installed on one side of the side box. The two racks are located on the bottom and top surfaces of the gear, respectively, and mesh with the gear. Two sliding grooves are opened on one side of the side box, and the two sliding grooves are connected to the inside of the outer protective frame. A slider is slidably installed in each of the two sliding grooves. One end of each slider is fixedly connected to one side of the two racks, and the other end of each slider is fixedly connected to one side of the two movable seats. When one rack moves, it drives the gear to rotate. When the gear rotates, it drives the other rack to move. The two racks move in opposite directions. When the two racks move away from each other, the sliders drive the two movable seats away from each other.

[0020] In the above technical solution, an electric push rod is further fixedly installed on one side of the inside of the side box. One end of the electric push rod is fixedly connected to one end of one of the racks. Activating the electric push rod will push one of the racks to move.

[0021] In the above technical solution, a mounting plate is further fixedly installed on the bottom surface of the outer protective frame, and the mounting plate has mounting holes. The mounting plate and mounting holes facilitate the installation and fixing of the outer protective frame.

[0022] In the above technical solution, the outer side wall of the inner protective frame is provided with multiple limiting holes, and a limiting post is fixedly installed on one side of each of the four clamping plates. The multiple limiting posts are movably sleeved in the multiple limiting holes. When the clamping plate abuts against the surface of the protective frame, the limiting post will be sleeved in the limiting hole, thereby fixing the inner protective frame and preventing the filter element body from loosening during installation.

[0023] The beneficial effects of this utility model are:

[0024] 1. The improved structure of this filter foam filter element allows for the following process when disassembling the inner protective frame and filter element body: activating the electric push rod moves one of the racks, which in turn drives a gear to rotate, which in turn drives the other rack to move. The two racks move in opposite directions. As the two racks move away from each other, the slider moves the two moving seats away from each other. When the two moving seats move away from each other, the connecting rod and the fixed seat work together to move the clamping plate away from the inner protective frame. Once the clamping plate is away from the inner protective frame, the restriction on the inner protective frame is released, allowing the inner protective frame to be removed from the outer protective frame.

[0025] 2. The improved structure of this filter foam filter element allows for the adjustment of the distance between multiple clamping plates by adjusting multiple sets of adjustment components during the installation of the inner protective frame and filter element body, depending on the specifications of the inner protective frame and filter element body. This enables the installation and fixation of the inner protective frame and filter element body, facilitating the installation and fixation of inner protective frames and filter element bodies of different specifications, enhancing the convenience of filter element body installation, and making it more practical.
