Problems solved by technology

[0003] At present, compressed air pipelines often use carbon steel pipes, which have poor corrosion resistance. After the system has been in operation for a period of time, the inner wall of the carbon steel pipes will fall off due to corrosion, and the fallen iron filings will flow with the compressed air. When the compressed air passes through the traditional interception filter, a large amount of iron filing impurities carried in it will be intercepted
A large number of iron filings impurities will not only block the core filter screen of the filter, but also easily damage the filter screen due to the hard nature of the iron filings, thus affecting the working efficiency of the entire compressed air preparation system. The damage of the core filter screen will cause the iron filings to enter the subsequent In the compressed air pipeline and equipment, the quality of compressed air is reduced, and the operating load of subsequent equipment is increased, resulting in increased energy consumption and waste of resources

Embodiment 1

[0037] Carbon steel is a common material in compressed air preparation systems. After the system has been in operation for a period of time, carbon steel is easily corroded, resulting in granular or flake impurities containing iron ions. The invention relates to a slag removal filter for removing magnetic impurities and nonmagnetic impurities from compressed air and other fluids.

[0038] Such as figure 1 Shown is a schematic structural view of a slag removal filter according to an embodiment of the present invention, the slag remover includes a cavity 1 and a U-shaped filter cartridge 2 arranged in the cavity 1, and the cavity 1 is provided with a fluid inlet 3 and the fluid outlet 4, the opening of the U-shaped filter cartridge 2 faces the top of the cavity 1,

[0039] The U-shaped filter cartridge 2 is provided with a magnetic element 5 for absorbing impurities in the fluid. One end of the magnetic element 5 is detachably connected to the bottom of the U-shaped filter cart...

Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 lies in the way that the magnetic element 5 is detachably connected to the U-shaped filter cartridge 2 .

[0056] refer to image 3 , which is another solution for the detachable connection between the magnetic element 5 and the U-shaped filter cartridge 2 . Specifically, the end of one end of the magnetic element 5 connected to the bottom of the U-shaped filter cartridge 2 is provided with a first groove 51, and at least one vertical lug 52 is arranged in the first groove 51, and the U-shaped filter cartridge The bottom of 2 is provided with a boss 21 matching with the first groove 51, and at least one second groove 22 matching with the vertical lug 52 is opened on the boss 21. When the magnetic element 5 is mounted on the bottom of the U-shaped filter cartridge 2 , the boss 21 is placed in the first groove 51 , and the vertical lug 52 is snapped into the second groove 22 , thereby realizing the fixation of the m...

Embodiment 3

[0058] In this embodiment, on the basis of Embodiment 2, a plurality of adsorption magnetic rods 5 are provided. refer to Figure 4 , this figure shows a top view of the specific arrangement of a plurality of adsorption magnetic rods 5 at the bottom of the U-shaped filter cartridge 2 . In this solution, the single adsorption magnetic rod 5 can be set as a more slender magnetic rod compared to Embodiment 1 and Embodiment 2. Since the magnetic impurities adsorbed by the adsorption magnetic rod 5 are all attached to the surface of the magnetic rod, therefore , the large adsorption surface area is not only conducive to improving the adsorption efficiency of magnetic impurities, but also can reduce the cleaning frequency and prolong the cleaning cycle, which is very suitable for batch continuous production process. Compared with a single thicker magnetic rod, the effective surface area of ​​multiple slender magnetic rods is greatly increased.

[0059] Such as Figure 4 As shown,...

Abstract

The invention relates to a deslagging filter which comprises a cavity and a U-shaped filtering drum arranged in the cavity, wherein a liquid inlet and a liquid outlet are formed in the cavity; an opening of the U-shaped filtering drum is faced to the top of the cavity; a magnetic element which is used for absorbing the impurities in the liquid is arranged in the U-shaped filtering drum; one end of the magnetic element is detachably connected with the bottom of the U-shaped filtering drum; the other end of the magnetic element extends along the opening direction of the U-shaped filtering drum; the liquid inlet is led into the U-shaped filtering drum; the exterior of the U-shaped filtering drum is communicated with the liquid outlet. The deslagging filter provided by the invention can be conveniently detached; the influence of magnetic impurities, such as scrap iron, in the liquid on a filter screen can be avoided; the deslagging effect is enhanced; the service life of the filter screen is prolonged; the times of replacing the filter screen is reduced; the cost is lowered; the running efficiency of the compressed air system equipment is further increased.

Description

technical field [0001] The invention relates to the technical field of purification equipment used in compressed gas preparation systems, in particular to a slag removal filter. Background technique [0002] In the compressed air preparation system, in order to make the compressed air meet the quality requirements of the industry, it is necessary to install a primary coarse filter, a microporous filter and a freeze dryer between the air compressor and the pure gas outlet to fully remove the compressed air. solid impurities and moisture. The traditional slag removal filter generally includes a filter housing, a fluid inlet and outlet, and a filter screen installed in the housing. When the fluid passes through the filter screen, most impurities will be intercepted, and the interception slag removal method is adopted. [0003] At present, compressed air pipelines often use carbon steel pipes, which have poor corrosion resistance. After the system has been in operation for a pe...
