Description

Grinding Johnson screen filter element

Technical Field

The utility model relates to the technical field of filter heads of desalinization devices, in particular to a grinding Johnson screen filter element.

Background

Traditional filter core is the plastics material mostly, in the use, and rivers under the long-term operation erode and vibrate the easy wearing and tearing filter core, finally can lead to the filter function inefficacy, and life is shorter, and the change filter core waste time just increases manufacturing cost.

SUMMERY OF THE UTILITY MODEL

The utility model mainly solves the technical problem of providing a grinding Johnson screen filter element which has the characteristics of high strength, uniform gap and high precision, enhances the strength of a filter unit, reduces the running resistance and ensures that the service life of the filter element is the same as that of equipment.

In order to solve the technical problems, the utility model adopts a technical scheme that: a abrasive johnson screen cartridge comprising: the filter unit comprises a filter unit, a front end cover and a rear end cover, wherein the front end cover is arranged at one end of the filter unit, the rear end cover is arranged at the other end of the filter unit, the filter unit adopts a Johnson net as a filter element and is made into a sieve tube shape, and meshes of the Johnson net form a medium leading-out channel.

In a preferred embodiment of the utility model, the filter unit is composed of support ribs arranged at intervals and enclosing into a cylindrical cage and a plurality of wedge-shaped bar blocks arranged around the support ribs, and a medium outlet channel is formed between adjacent wedge-shaped bar blocks.

In a preferred embodiment of the utility model, the wedge-shaped bars are in a V-shaped structure, and a medium outlet channel formed between two adjacent V-shaped wedge-shaped bars is in a horn shape.

In a preferred embodiment of the present invention, a protruding step is integrally formed on an end surface of the cylindrical support rib facing the wedge-shaped bar block, and the protruding step is welded with the wedge-shaped bar block.

In a preferred embodiment of the present invention, the filter unit, the front end cap and the rear end cap are made of metal.

In a preferred embodiment of the utility model, the center of the front end cover is preset with a drainage hole for introducing the medium to be filtered into the filter unit.

The utility model has the beneficial effects that: this practical grinding Johnson net filter core has intensity height, no welding deformation, the gap is even, the characteristics that the precision is high, and the medium is drawn forth the passageway and is the loudspeaker column structure, has strengthened filter core intensity and has reduced the running resistance, and filtration efficiency is high, is difficult to block up, and the metal material prolongs the life of filter core to practice thrift the cost.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, a polishing johnson screen cartridge of the present invention comprises: the filter comprises a filter unit 1, a front end cover 2 and a rear end cover 3, wherein a drainage hole for leading a medium to be filtered into the filter unit is preset in the center of the front end cover, the front end cover is arranged at one end of the filter unit, the rear end cover is arranged at the other end of the filter unit, the filter unit adopts Johnson net as a filter element and is made into a sieve tube shape, specifically, the filter unit comprises support ribs 4 which are arranged at intervals and are enclosed into a cylindrical cage frame and a plurality of wedge-shaped bar blocks 5 which are wound in the support ribs, a medium leading-out channel 6 is formed between the adjacent wedge-shaped bar blocks, the structure has the characteristics of high strength and strong permeability, the filter element has an automatic backwashing function, water flows through the filter element from inside to outside in normal operation, the water flows from outside to inside in backwashing, the performance of the filter element can be restored to an initial state after the backwashing is finished, the filter element is more wear-resistant, and the frequency of replacing the filter element is reduced, the service life of the device is kept the same as that of the equipment, so that the running cost of the equipment can be reduced.

Specifically, the wedge-shaped strips are of V-shaped structures, and a medium leading-out channel formed between every two adjacent V-shaped wedge-shaped strips is horn-shaped, so that the effective filtering area can be increased, and the cleaning is easy.

Specifically, integrated into one piece has protruding step 7 on cylindric support rib towards the terminal surface of wedge strip piece, protruding step with wedge strip piece welded connection, the sound construction is stable, increase of service life.

Specifically, filter element, front end housing and rear end cap are the metal material, and corrosion-resistant effect is good, and the metal material prolongs the life of filter core to practice thrift the cost.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
