[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: Figures 1-4 As shown, the utility model provides a cartridge high-efficiency filter, comprising: an end seat 1 and an end cover 2, a protective net 5 is arranged between the end seat 1 and the end cover 2, a filter material 4 is arranged on the inner side of the protective net 5, a handle 3 is fixedly connected to the top of the end cover 2, the cross-section of the handle 3 is trapezoidal, a circular hole is opened at the center of the top of the end cover 2, the bottom of the filter material 4 is fitted with the top of the end seat 1, the top of the filter material 4 is fitted with the bottom of the end cover 2, the holes opened on the outer surface of the protective net 5 are diamond-shaped, and the protective net 5 and the filter material 4 are matched with each other.

[0022] The effect achieved by the entire embodiment 1 is that, when the cylindrical high-efficiency filter is in use, a protective net 5 is set between the end seat 1 and the end cover 2 to prevent external objects from colliding with the filter material 4 and causing damage. The holes opened on the surface of the protective net 5 are diamond-shaped, which can allow the conveying medium to flow between the protective net 5 and the filter material 4, and at the same time can serve as a support and fixation between the end seat 1 and the end cover 2. A circular hole is opened at the center of the top of the end cover 2 to facilitate the entry of the conveying medium. When flowing from the inside to the outside, impurities in the conveying medium will be blocked by the filter material 4 and retained inside the filter, thereby playing a filtering role. By fixing the handle 3 on the top of the end cover 2, it is convenient for personnel to install it after grasping the handle 3, effectively avoiding the personnel's hands from touching and damaging the filter material 4 during the installation limit, solving the problem in the background technology that the outer structure of the cylindrical high-efficiency filter is cylindrical and not easy to grasp and install, resulting in the personnel's hands easily touching the surface of the filter material 4 during the installation process, causing wrinkle displacement and surface contamination of the filter material 4.

[0023] Example 2: Figures 1-4 As shown, a plurality of blocks 6 are fixedly connected at equal intervals on the outer surface of the end seat 1 near the bottom, the filter material 4 is located between the end seat 1 and the end cover 2, an annular groove 7 is provided on the outer surface of the end cover 2, and a sealing ring 8 is provided on the inner surface of the annular groove 7.

[0024] The effect achieved by the entire embodiment 2 is that, when in use, a plurality of clamping blocks 6 are equidistantly arranged on the outer surface of the end seat 1, so that it is convenient to install and fix by snap connection at the delivery inlet end of the equipment, and an annular groove 7 is provided on the outer surface of the end cover 2 to facilitate the installation of the sealing ring 8 and prevent the sealing ring 8 from falling off, and the practicability is high.

[0025] Working principle: When the cylindrical high-efficiency filter is in use, a protective net 5 is set between the end seat 1 and the end cover 2 to prevent external objects from colliding with the filter material 4 and causing damage. The holes on the surface of the protective net 5 are diamond-shaped, which can allow the conveying medium to flow between the protective net 5 and the filter material 4, and at the same time serve as a support and fixation between the end seat 1 and the end cover 2. A circular hole is opened at the center of the top of the end cover 2 to facilitate the entry of the conveying medium. When flowing from the inside to the outside, impurities in the conveying medium will be blocked by the filter material 4 and retained inside the filter, which plays a filtering role. The handle 3 is fixed on the top of the end cover 2 to facilitate the installation of personnel by grasping the handle 3, effectively avoiding the damage of the filter material 4 by the personnel's hands during the installation limit. A plurality of blocks 6 are equidistantly set on the outer surface of the end seat 1, which is convenient for installation at the conveying inlet end of the equipment and fixed by snap connection. The annular groove 7 is opened on the outer surface of the end cover 2 to facilitate the installation of the sealing ring 8 to prevent the sealing ring 8 from falling off, which is highly practical.
