Abstract

The utility model discloses a magnetism filter core belongs to hydraulic oil magnetism filter core field, solves the iron fillings on the magnet that current magnetism filter core exists and is difficult to the problem of clearance. The utility model discloses a shell and a plurality of magnet are equipped with the oil-out on the shell, still include the inner skleeve, and the inner skleeve inner wall is equipped with the skeleton, and magnet demountable installation is on the skeleton, and on the inner skleeve inner wall including a plurality of magnet equipartitions, the inner skleeve is established in the shell, and the gland is installed at the top of inner skleeve and shell, is equipped with the oil inlet on. The utility model discloses can adsorb iron fillings on interior sleeve outer wall, because the separation of gland, iron fillings can not directly adsorb on magnet, during the clearance, take out magnet from the inner skleeve, the iron fillings of inner skleeve surface are wiped gently and have just fallen, and the clearance is swift rapid, the clean up, and magnet does not need the clearance, labour saving and time saving.

Description

Magnetic filter element

Technical Field

The utility model belongs to hydraulic oil magnetism filter core field.

Background

The hydraulic system has the advantages of convenient use, automatic overload protection, convenient control, long service life, quick response, small inertia, easy automation realization and the like, and is widely applied to equipment such as vehicles, working condition equipment, robots and the like. Hydraulic system can produce impurity such as iron fillings in service certainly, aggravates equipment wear and tear and degradation, and fluid is changed frequently, shortens equipment life, and consequently, hydraulic system all designs filter equipment and has filtered the reason to fluid. The magnetic filter element of TY220 bulldozer gear box and steering clutch adopts 5 pieces of ring magnet fixed on the frame inside the magnetic filter element casing and the magnetic adsorption of the magnet to eliminate iron filings from the oil liquid in the gear box and steering clutch. The cleanness of hydraulic oil is guaranteed through the circulation of fluid, and iron fillings are required regularly to be cleared up after adsorbing on the magnet surface. Because iron fillings adhere on magnet, magnet soak in fluid, the clearance difficulty, the clearance is unclean, this makes the magnetic filter core shorten clearance cycle, has increased fluid and has changed the frequency, has reduced the live time of vehicle. The problem of scrap iron cleaning of magnetic filter elements always puzzles maintenance personnel.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a magnetic filter element to solve the problem that iron fillings on the magnet that current magnetic filter element exists are difficult to the clearance.

The technical scheme of the utility model is that: the utility model provides a magnetic filter element, includes shell and a plurality of magnet, is equipped with the oil-out on the shell, still includes the inner skleeve, and the inner skleeve inner wall is equipped with the skeleton, and magnet demountable installation is on the skeleton, and on the inner skleeve inner wall including a plurality of magnet equipartitions, the inner skleeve was established in the shell, and the gland is installed at the top of inner skleeve and shell, is equipped with the.

As a further improvement of the utility model, the inner sleeve is made of 439 stainless steel.

As a further improvement of the utility model, the gland, the inner sleeve and the shell are connected through bolts.

As a further improvement of the utility model, a sealing ring is arranged between the gland, the inner sleeve and the shell.

As a further improvement, the magnet is a ring magnet, and the magnet is uniformly distributed along the length direction of the inner sleeve.

The utility model has the advantages that: the utility model discloses add the inner skleeve on the basis of current magnetism filter core, installed magnet in the inner skleeve, with the inner skleeve in the shell, then installed the gland and can use. The inner sleeve is made of 439 stainless steel, and the 439 stainless steel has the characteristics of high magnetic conductivity and low residual magnetism. In the operation process of the hydraulic system, the 439 stainless steel has high magnetic conductivity, and due to the isolation of the gland, iron chips are only adsorbed on the surface of the inner sleeve and not adsorbed on the magnet, the magnet is taken out of the inner sleeve during cleaning, and the iron chips on the outer surface of the inner sleeve are gently wiped off due to the extremely low residual magnetism of the 439 stainless steel, so that the cleaning is rapid and fast, the cleaning is clean, the magnet does not need to be cleaned, and the time and the labor are saved. The utility model discloses reduced the clearance degree of difficulty of iron fillings, clearance iron fillings are clean, reduce clearance time, and extension fluid replacement cycle, labour saving and time saving improves the operating time of vehicle, has improved work efficiency.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in figure 1, a magnetic filter element, including shell 1 and a plurality of magnet 2, be equipped with oil-out 9 on the shell 1, still include inner skleeve 3, inner skleeve 3 inner wall is equipped with skeleton 4, magnet 2 demountable installation is on skeleton 4, on the inner skleeve 3 inner wall of a plurality of magnet 2 equipartitions, inner skleeve 3 establishes in shell 1, gland 5 is installed at the top of inner skleeve 3 and shell 1, is equipped with oil inlet 8 on gland 5.

The inner sleeve 3 is made of 439 stainless steel.

The gland 5, the inner sleeve 3 and the outer shell 1 are connected through bolts 7.

And a sealing ring 6 is arranged among the gland 5, the inner sleeve 3 and the shell 1.

Magnet 2 is annular magnet, and magnet 2 is along inner skleeve 3 length direction equipartition.

Install magnet 2 on skeleton 4 in inner skleeve 3, with inner skleeve 3 cover in shell 1, connect gland 5, inner skleeve 3 and shell 1 through bolt 7, can use. In the operation process of the hydraulic system, oil flows in from the oil inlet 8 and flows out from the oil outlet 9, because 439 stainless steel has high magnetic conductivity, and because the isolation of the gland 5, iron filings are only adsorbed on the surface of the inner sleeve 3 and are not adsorbed on the magnet 2, the magnet 2 is taken out from the inner sleeve 3 during cleaning, because 439 stainless steel has extremely low residual magnetism, the iron filings on the surface of the inner sleeve 3 are gently wiped off, the cleaning is rapid and fast, the cleaning is clean, the magnet does not need to be cleaned, and the time and the labor are saved.
