Detailed Description

A magnetic filter according to the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 3, a magnetic filter includes a two-way tee 1, a flow-through chamber housing 2, a medium chamber 21 disposed in the flow-through chamber housing 2, and a detachable magnetic ring sleeve 3, the magnetic ring sleeve 3 is fastened to a fastening groove 20 on an outer diameter of the flow-through chamber housing 2, and a magnet 30 generating a magnetic force to the medium chamber 21 is installed in the magnetic ring sleeve 3.

The magnetic ring sleeve 3 is C-shaped and is provided with more than two slotted holes 31 for placing the magnets 30. In fig. 3, two slots 31 of the magnetic ring sleeve 3 are each provided with a magnet 30. The magnet 30 passes through the circulation chamber housing 2, adsorbs iron impurities or iron ion-containing particles in the medium chamber 21, and is fixed to the circulation chamber housing 2 to prevent the iron impurities or iron ion-containing particles from entering the pipe again for circulation.

The circulation cavity shell 2 is made of nonmagnetic insulating materials, and nylon materials are adopted in the embodiment, so that magnetic obstruction can be reduced.

The magnetic ring sleeve 3 adopts a detachable structure, the C-shaped structure has elasticity, the magnetic ring sleeve can be directly deformed and pulled out from the clamping groove 20, and when the magnetic ring sleeve 3 is separated from the circulation cavity shell 2, the iron-containing impurities lose adsorption force and fall to the lower part of the medium cavity 21. And is discharged with the blow-off valve 5.

The magnetic ring sleeve 3 is connected with a suspension buckle 4, and the other end of the suspension buckle 4 is fixed between the circulation cavity shell 2 and the blow-down valve 5. Effectively preventing the magnetic ring sleeve 3 from being lost.

The blowoff valve 5 is fixed with the circulation cavity shell 2 through a clamping insert 6, and the upper end of the clamping insert 6 is provided with a flange limiting structure 60 fixed with the circulation cavity shell 2. The circulation cavity shell 2 is made of plastic materials, such as nylon or polyformaldehyde materials, is difficult to connect with the blowoff valve 5 made of copper alloy materials, the plastic has different shrinkage and expansion coefficients of the plastic and metal, the strength difference is large, and the hardness of the plastic is insufficient by adopting the traditional threaded connection. This problem can be solved well by the use of the retaining insert 6.

The clamping insert 6 and the blowoff valve 5 are matched with the circulation cavity shell 2 in a preset size distance, and both are made of metal materials, so that the problem of connection torque is solved. The inside of the upper part of the clamping insert 6 is funnel-shaped. Make things convenient for impurity to drop and do not have the platform of piling up, can effectively clear away totally.

However, the inner side of the upper part of the clamping insert 6 is inconvenient to install and fix by adopting a funnel-shaped structure, so that the upper part of the clamping insert 6 is provided with a groove cutting structure 61, and the assembly requirement is met.

Along with the water flow medium enters the medium cavity 21 through the two-channel tee joint 1, the space is suddenly enlarged, air is accumulated in the cavity, the air in the pipeline can generate steam explosion and damage pipeline equipment, oxygen contained in the air can oxidize the equipment, and therefore the magnetic filter is further provided with the exhaust valve 7 on the upper portion of the medium cavity 21.

The double-channel tee joint 1 is provided with an isolation pipe 10 which separates a water inlet cavity 11 and a water outlet cavity 12 of the double-channel tee joint 1, and the water inlet cavity 11 and the water outlet cavity 12 are arranged on the same side on the side connected with the circulation cavity shell 2. The double-channel tee joint 1 is of a double-cavity structure.

The medium cavity 21 is further provided with a filter screen 8, and the filter screen 8 is arranged on the medium outflow channel of the two-channel tee joint 1. The filter screen 8 can further reduce the flow velocity of the medium, settle impurities in the medium and more fully remove air in the medium.
