[0036] See Figures 1 to 11 The iron powder adsorption device shown includes a pipe 100, a housing 200, a magnet assembly 300, and a cover 400 for use in the inlet pipe of a fan.

[0037] Pipeline 100 is disposed between two pipe expansion joints. In this embodiment, both ends of pipeline 100 are provided with connecting flanges 110. The connecting flanges 110 are provided with connecting holes 111 for bolt assembly 10 to pass through and connect to the two pipes. Specifically, bolt assembly 10 consists of bolts and nuts.

[0038] The outer casing 200 is disposed on the outer wall of the pipe 100. In this embodiment, the outer casing 200 consists of a top plate and a bottom plate. There are four outer casings 200, which are respectively arranged in the front, back, left, and right directions of the pipe. Specifically, the outer casing 200 is made of stainless steel to prevent attraction to magnets.

[0039] Several magnet components 300 are arranged laterally at intervals on the outer casing 200 to adsorb iron powder in the medium. In this embodiment, the magnet components are arranged in three rows. Three rows of magnet components are arranged in all four directions of the pipe 100, and the first row of magnet components is staggered from the second row of magnet components. The third row of magnet components is arranged in the same way as the first row of magnet components. Its function is to prevent iron powder or other metal foreign objects between the magnets from passing through and causing damage.

[0040] A cover 400 is disposed on the housing 200 and is used to prevent the magnet components 300 from being affected by external factors. The cover 400 isolates the magnet components 300 from the outside environment and protects them from external influences. In this embodiment, the cover 400 is made of stainless steel to prevent it from being attracted to magnets.

[0041] Each magnet assembly 300 includes a magnet 310 disposed within a housing 200, two magnet handle connectors 320 disposed on the magnet 310, and a magnet handle 330 disposed between the two magnet handle connectors 320. In this embodiment, one end of the two magnet handle connectors 320 is connected to a first threaded hole 311 on the magnet 310 via an internal hexagonal head screw 20 and a flat washer. The other end of the two magnet handle connectors 320 has a threaded hole 321, and the threaded hole 321 is detachably connected to the magnet handle 330 via a fastener 30. The magnet assembly 300 is designed for easy disassembly and installation.

[0042] The interior of the housing 200 is provided with a plurality of magnet isolation plates 210 for separating each magnet assembly 300. The plurality of magnet isolation plates 210 are two magnet isolation plates arranged on the left and right sides of each magnet assembly 300 to prevent the magnets of the two magnet assemblies 300 from attracting each other. Specifically, the magnet isolation plates 210 are made of stainless steel to prevent attraction with magnets.

[0043] A magnet limiting component 410 is provided on the side of the cover 400 facing the pipe 100 to prevent each magnet assembly 300 from flipping over, and a handle 420 is provided on the side of the cover 400 away from the pipe 100 for easy installation and removal. In this embodiment, the magnet limiting component 410 includes a limiting tube disposed inside the cover 400 and in contact with each magnet assembly 300. Specifically, the handle 420 and the limiting tube are made of stainless steel.

[0044] To allow the medium to pass through, the middle part of the pipe 100 is a hollow structure 100a. In this embodiment, the pipe 100 is arranged in a square structure.

[0045] The working principle of this utility model is as follows:

[0046] After assembling the present invention, before starting the fan, install the present invention between the two pipe expansion joints. The connecting flanges 110 at both ends of the pipe 100 are connected to the two pipes by bolts and nuts through the connecting holes 111. When the fan starts, the medium flows through the present invention. The iron powder in the medium is attracted by the magnetic force of the magnet assembly 300 and is constrained on the inner wall of the pipe 100 of the present invention. When the fan is under maintenance, loosen the fasteners 30, take out the present invention, and take out the magnet assembly 300. The iron powder loses the magnetic attraction and falls off automatically. The present invention will not have any impact on the airflow field or the efficiency of the fan.

[0047] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0048] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0049] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0050] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
