[0002] The filter cartridge belongs to a surface filter element, which blocks off the particulate matter in the gas by using the micro-porous structure formed on the surface of the filter material. The filter cartridge is a commonly used dust catcher, which has the characteristics of high trapping rate, small resistance, and easy sampling in the flue, and is widely used for sampling of particulate matter, cooking fume, asphalt smoke, chromic acid mist, sulfuric acid mist and other pollutants. According to the material, the filter cartridge can be divided into two types: glass fiber filter cartridge and corundum filter cartridge. The most widely used in daily application is the glass fiber filter cartridge, which is made of ultra-fine glass fiber and has a trapping rate of more than 99.9% for dust particles larger than 0.5 μm.

[0003] In the prior art, the external structure of the filter cartridge is mostly made of flexible material. Due to the characteristics of the flexible material, the filter cartridge is easily subjected to external forces such as extrusion and impact during handling, storage and transportation, which may cause deformation, rupture or even breakage. Once the filter cartridge is damaged, its filtering structure may be damaged, which may cause a sharp decline in filtering performance and fail to achieve the expected filtering effect. In addition, due to the large coverage area of the flexible component on the outside of the filter cartridge and the lack of sufficient structural strength, it is difficult to prevent collision and damage by external fixation during transportation. The traditional packaging method often fails to provide sufficient protection, which makes the filter cartridge face higher risks during long-distance transportation. SUMMARY

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figure 1 - Figure 5 The utility model provides a kind of pleated filter cartridge anti-collision device technical solutions:

[0024] In the embodiments of the utility model, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 Including box 1, the inside of box 1 is installed with fixed assembly 4, fixed assembly 4 includes the rotation connection of the bottom end of box 1 with pivot 401, both ends of pivot 401 are installed with two first mounting plates 402, the outer wall of each first mounting plate 402 is equipped with multiple sliding grooves 403, the inner wall of each sliding groove 403 is slidably connected with sliding block 404, the end of sliding block 404 away from sliding groove 403 is installed with fixed plate 405, the top end of fixed plate 405 is installed with support rod 406, the top end of support rod 406 is connected with abutting plate 407, the end of pivot 401 close to two first mounting plates 402 is installed with second mounting plate 408.

[0025] It should be noted that: multiple abutting plates 407 start together, because the shape of abutting plate 407 is arc-shaped. Multiple abutting plates 407 can form a circle, and the circular abutting plate 407 can contact the inner wall of the filter cartridge more, increasing the friction of the abutting plate 407 to the inner wall of the filter cartridge.

[0026] Please refer to Figure 5 The inside of box 1 is equipped with slot 2, the bottom end of slot 2 is installed with multiple shock absorbing assemblies 5, each shock absorbing assembly 5 includes damping rod 501 installed in the inner bottom wall of slot 2, the end of damping rod 501 away from the inner bottom wall of slot 2 is connected with extension rod 502, spring 503 is sleeved on the outer wall of damping rod 501, and one end of spring 503 is connected with the bottom end of slot 2.

[0027] It should be noted that the cooperation of the spring 503 and the damping rod 501 and the extension rod 502 makes the assembly more smoothly switch from one state to another state in the transition process, reducing the vibration caused by mutation.

[0028] Referring to Figure 2 The shaft 401 is connected with the protective sleeve 3 near one end of the inner bottom wall of the slot 2, and the extension rod 502 is fixedly connected with the bottom end of the protective sleeve 3.

[0029] It should be noted that the fixed connection of the extension rod 502 and the protective sleeve 3 ensures the stability of the connection between the assemblies, and when external vibration occurs, the damping assembly 5 can be linked to reduce vibration.

[0030] Referring to Figure 1 The control panel 6 is installed on one side of the outer wall of the box 1, a plurality of control buttons are installed on the outer wall of the control panel 6, and the control panel 6 is electrically connected with the shaft 401.

[0031] It should be noted that the control panel 6 can adjust the width of the fixed assembly 4 to ensure that the abutting plate 407 always closely fits the inner wall of the filter cartridge, and the control panel 6 can make it more convenient for the staff to adjust the assembly.

[0032] Referring to Figure 4 The shape of the abutting plate 407 is arc-shaped, the material of the abutting plate 407 is elastic material, and the surface of the abutting plate 407 is uniformly paved with anti-skid lines.

[0033] It should be noted that the arc-shaped abutting plate 407 can better adapt to the curved shape of the inner wall of the filter cartridge, and ensure that it closely fits the inner wall of the filter cartridge during adjustment. The arc-shaped design helps the fixed assembly 4 to reduce the gap between the inner wall of the filter cartridge, and increases the friction force on the surface of the abutting plate 407.

[0034] Working principle: when the staff by pressing the control panel 6 outside the box 1 of the outer surface of its start after the adjustment, the rotating shaft 401 according to the different rotation to let the slider 404 installed on the fixed plate 405 in the inner wall of the sliding groove 403 rotation, and the width of the sliding groove 403 and the width of the slider 404 fit, to ensure the stability and precision of movement, sliding groove 403 accurately guide the direction of movement of the slider, limit the transverse movement of the slider 404, to ensure that it can only rotate in the predetermined path, to ensure the stability of the assembly, while the slider 404 and fixed plate 405 for fixed connection, when the slider 404 will move when the support rod 406 push plate 407 outward extension, the surface of the plate 407 design has anti slip lines, these lines increase the friction with the filter cartridge inner wall, to ensure that the fixed assembly will not slide during transportation, so as to enhance the fixed effect, multiple plate 407 arc surface formed a circular can be connected with the inner wall of the filter cartridge, and the bottom end of the sleeve 3 is provided with a plurality of damping components 5, spring 503 through its elastic properties, can absorb and disperse vibration energy, thereby reducing the resonance phenomenon of the box 1, while the damper rod 501 by providing additional resistance, further inhibit the amplitude of vibration, make the system more stable, spring 503 when subjected to external impact, spring 503 can quickly compress and release energy, to absorb most of the impact force, extension rod 502 and damper rod 501 by limiting the excessive compression and rebound of spring 503, prevent spring 503 due to impact and produce too big and damage.
