Example 1

With reference to the accompanying drawing 1, a magnetic filter comprises a main body 100, a communicating cavity 101 is formed in the main body 100, an extending portion 20 is arranged on one side of the main body 100, an included angle exists between the extending portion 20 and the main body 100, a filtering cavity 201 is formed in the extending portion 20, the communicating cavity 101 is communicated with the filtering cavity 201, an end cover 30 is arranged in the filtering cavity 201, a bearing bracket 301 is arranged on the end cover 30, the bearing bracket 301 is close to the communicating cavity 101, one end of the communicating cavity 101 is sealed, a magnet 302 is arranged in the bearing bracket 301, a mounting frame 303 is further arranged on the end cover 30, and a filter screen 304 is arranged between the mounting frame 303 and the bearing bracket 301.

The magnetic filter of this embodiment can effectively adsorb ferromagnetic particulate matter such as iron rust, iron fillings in the pipeline to carry out effectual collection to these ferromagnetic particulate matters, and to the ferromagnetic particulate matter after collecting, after the magnetic filter who takes out this embodiment, because magnet 302 realizes setting through support bracket 301, ferromagnetic particulate matter only adsorbs in the support bracket 301 outside, after taking out magnet 302, ferromagnetic particulate matter drops automatically thereupon.

The magnetic filter of this embodiment is provided with filter screen 304, and filter screen 304 passes through mounting bracket 303 and realizes fixed mounting, and in this embodiment, can adopt multiple cooperation mode, for example interference fit, screw-thread fit etc. between filter screen 304 and the mounting bracket 303 to realize that filter screen 304 conveniently dismantles and installs. An interference fit is one preferred mode, because filter screen 304 and mounting bracket 303 need frequently be dismantled to in the clearance of ferromagnetic particle impurity, consequently the installation between filter screen 304 and the mounting bracket 303 is difficult loaded down with trivial details. In addition, because the influence of liquid and ambient temperature, according to expend with heat and contract with cold principle, certain degree of deformation may take place for filter screen 304, interference fit between filter screen 304 and the mounting bracket 303 still can further guarantee the stability of filter screen 304 installation.

In this embodiment, when liquid flows through the communicating chamber 101, the filter screen 304 can block the impurity with a large size to avoid the impurity to cause damage to the support bracket 301 or the magnet 302 in the filter chamber 201, and also can effectively prevent the blockage of the communicating chamber 101, and the small ferromagnetic particles can penetrate through the filter screen 304 and be adsorbed on the outer wall of the support bracket 301, so as to collect the fine ferromagnetic particles.

In this embodiment, the end cap 30 is fixed to the extension portion 20 through the mounting frame 303, and multiple fitting manners, such as interference fit, thread fit, and the like, can be adopted between the mounting frame 303 and the filter cavity 201, so that the end cap 30, the magnet 302, and the filter screen 304 can be conveniently detached and installed, and further the practicability of the magnetic filter is improved.

In addition, one end of the support bracket 301 close to the communication chamber 101 is closed, so that the magnet 302 can be effectively prevented from falling into the communication chamber 101.

In the present embodiment, an angle exists between the axis of the extension portion 20 and the axis of the main body 100, and the angle may take any value within 90 ° or 90 °, and the angle may be set according to specific conditions such as processing difficulty, ferromagnetic particle impurity content, and the like.

As an alternative embodiment of this embodiment, a blocking cap 305 is further disposed in the support bracket 301, and the magnet 302 contacts against the blocking cap 305. In this embodiment, since the effective contact area between the magnet 302 and the liquid medium is limited, and the length of the magnet 302 is generally smaller than the depth of the support bracket 301 in order to save cost, in order to ensure the stability of fixing the magnet 302, the blocking cap 305 can be plugged into the support bracket 301, and one end of the blocking cap 305 abuts against the magnet 302, so that the magnet 302 cannot move in the support bracket 301, thereby ensuring the stability of fixing the magnet 302.

It is contemplated that the engagement between the blanking cap 305 and the support bracket 301 is not limited, and any optional form such as a threaded engagement, an interference fit, a bolt, or a positioning bolt may be used between the blanking cap 203 and the support bracket 301 to achieve a secure engagement between the blanking cap 203 and the support bracket 301.

As an alternative embodiment of this embodiment, the plugging cap 305 and the support bracket 301 are engaged by screw threads. When the plug cap 305 is in threaded fit with the support bracket 301, the magnetic medium can be mounted and replaced conveniently on the premise that the magnet 302 is stably arranged.

As an alternative embodiment of this embodiment, a fitting 202 is further disposed in the extension 20, and the fitting 202 is fixedly engaged with the end cap 20. Because the magnetic particle impurities such as iron filings adsorbed on the bearing bracket 301 need to be cleaned frequently, the end cover 30 can be detached and installed frequently, so that the contact part between the end cover 30 and the extension part 20 can be abraded inevitably, and the like, in order to ensure the sealing performance of the magnetic filter, the fitting part 202 can be arranged in the extension part 20, the fitting part 202 is used for replacing the extension part 20 to be contacted with the end cover 30, the abrasion of the extension part 20 is greatly reduced, the fitting part 202 can be replaced conveniently, and the service life of the magnetic filter is prolonged.

In the present embodiment, the assembly between the extension 20 and the fitting member 202, and the assembly between the fitting member 202 and the end cover 20 can be implemented in various manners, such as by screw-fitting, interference-fitting, bolt, set screw, or adhesive, and any assembly manner can be selected according to practical requirements.

As an alternative embodiment of this embodiment, a sealing member 203 is disposed between the end cap 30 and the filter cavity 201. In this embodiment, in order to make the installation of the end cap 30 meet the requirement of sealing performance, a sealing member 203 may be disposed between the end cap 30 and the filter cavity 201, and the sealing member 203 may be a sealing structure such as a sealing ring, or may be any structure capable of achieving a sealing effect, such as glue capable of filling a gap between the end cap 30 and the filter cavity 201.
