The technical scheme of cell size filter is:
Cell size filter, comprise tramp iron separator, tramp iron separator comprises tramp iron separator cylindrical shell, is provided with the adsorption sleeve be made up of magnetic material in the inner chamber of tramp iron separator cylindrical shell, in adsorption sleeve, activity is equipped with permanent magnet, the body of adsorption sleeve offers the opening passed for described permanent magnet.
The axis of described adsorption sleeve is extended along the vertical direction, and the endoporus lower end of adsorption sleeve is by plugging structure shutoff, and described opening is made up of the upper port of the endoporus of described adsorption sleeve.
The upper end of adsorption sleeve is fixedly arranged on the upper end of described tramp iron separator cylindrical shell, and the lower end of adsorption sleeve overhangs and arranges.
The upper end of permanent magnet is provided with cleaning pull bar, and the upper end of tramp iron separator cylindrical shell is installed with for being fixedly linked with described cleaning pull bar after permanent magnet is taken out by described adsorption sleeve and covers at the protective cover of described permanent magnet periphery.
The beneficial effects of the utility model are: when normally using, permanent magnet is as in adsorption sleeve, adsorption sleeve magnetizes by permanent magnet, metal impurities can be adsorbed on the outer surface of adsorption sleeve, when needing cleaning in use for some time, taken out by the opening part of permanent magnet by adsorption sleeve, the magnetization of adsorption sleeve disappears, and can be removed by the metal impurities on adsorption sleeve easily.

Detailed description of the invention
The embodiment of cell size filter is as shown in Fig. 1 ~ 6: membrane pump 2, first filter 4, second filter 5 and the tramp iron separator 6 that comprise order setting from front to back.Wherein tramp iron separator comprises and has tramp iron separator charging aperture 14, the tramp iron separator cylindrical shell 13 of tramp iron separator discharging opening 10, the adsorption sleeve 11 be made up of magnetic material that axis extends along the vertical direction is provided with in the inner chamber of tramp iron separator cylindrical shell 13, the upper end of adsorption sleeve 11 is fixedly arranged on the upper end of tramp iron separator cylindrical shell 13, the lower end of adsorption sleeve 11 overhangs and arranges, the endoporus lower end of adsorption sleeve is by plugging structure shutoff, in adsorption sleeve, guiding activity is equipped with permanent magnet 9, permanent magnet 9 is the rod shaped structure with adsorption sleeve endoporus adaptation, the upper port of the endoporus of adsorption sleeve forms the opening passed for permanent magnet 9, adsorption sleeve has three in the present embodiment, each adsorption sleeve along the longitudinal direction interval is arranged, corresponding permanent magnet also has three, three permanent magnets lead respectively and are movably set in corresponding adsorption sleeve.The upper end of permanent magnet is provided with cleaning pull bar 3, the upper end of tramp iron separator cylindrical shell is installed with protective cover 8, protective cover 8 is provided with the fixed structure for fixing cleaning pull bar after taking out in permanent magnet is by corresponding adsorption sleeve, fixed structure is gear edge, clean pull bar by permanent magnet by after proposition in corresponding adsorption sleeve, cleaning pull bar is mounted on gear edge above, now protective cover covers at the periphery of permanent magnet, avoids permanent magnet to be exposed in air.Fig. 1 middle term 1 represents combined feed mouth, and item 7 represents total discharging opening; Item 12 represents the base of tramp iron separators.
First, the structure of the second filter is identical, now only the structure of the first filter is described in detail, first filter 4 comprises the vertical filter cylinder 21 arranged, the upper end of filter cylinder is provided with end cap, end cap is provided with filter core, filter core comprises the inner frame 19 with end cap eccentric setting, purchasing ore 20 and in being arranged at, filter screen 18 between purchasing ore, in, purchasing ore and filter screen all by screw thread spinning on end cap, end cap is provided with and the filter discharging opening of the inner space of inner frame and the filter charging aperture that is communicated with the exocoel of purchasing ore, filter discharging opening is arranged with inner frame is concentric, filter discharging opening is connected with discharge hole joint 16, filter charging aperture is connected with charging aperture joint 15, end cap is also provided with Pressure gauge 7, in the present embodiment, Pressure gauge is electric contact type pressure gauge.
During use, cell size after membrane pump sequentially through the first filter, second filter and tramp iron separator, through the first metre filter, cell size enters filter by the periphery of purchasing ore, to flow into from outside to inside in the inner chamber of inner frame and finally to be discharged by filter discharging opening, when inner frame ensure that cell size flows into from outside to inside, filter screen can not by punching distortion, because the volume of purchasing ore periphery is larger, therefore the filter area of cell size can be increased, improve filter effect, due to filter screen and interior, the equal spinning of purchasing ore is on end cap, so filter screen is conveniently replaced, when strainer filtering resistance increases, electric contact type pressure gauge sends warning, now need to clean or more renew filter screen to filter screen to use, because end cap is arranged at the upper end of filter cylinder, also make the replacing of filter core more simple and convenient.After use one end time, adsorption sleeve also adsorbs more metal impurities, now need to be cleaned adsorption sleeve by clear water, by cleaning pull bar, each permanent magnet is proposed by corresponding adsorption sleeve, then cleaning pull bar is fixed on protective cover, permanent magnet is avoided cruelly to leak in air, after taking out in permanent magnet is by corresponding adsorption sleeve, adsorption sleeve just loses magnetic, now can easily the metal impurities of adsorption sleeve appearance be washed by clear water, again permanent magnet is positioned in corresponding adsorption sleeve subsequently and can reuses, adsorption sleeve can also avoid cell size to contact with permanent magnet, thus ensure the drying regime of permanent magnet, purchasing ore the structural strength that can increase filter core is set.
In other embodiment of this cell size filter, the number of adsorption sleeve and permanent magnet can also be arranged as required, such as the number of adsorption sleeve, permanent magnet is one, two, four or other number; Cleaning pull bar and protective cover can not also be established, and now permanent magnet can directly take out by operating personnel; Adsorption sleeve can also be horizontally disposed with or put into certain angle of inclination, and when adsorption sleeve horizontal positioned, adsorption sleeve can be opening up U-lag structure, and now the notch of U-lag structure passes by adsorption sleeve for permanent magnet; The lower end of adsorption sleeve also can be fixedly arranged on tramp iron separator cylindrical shell; Inside and outside skeleton and filter screen can also be fixedly arranged on integrally structure, and then whole filter core is assemblied on end cap, when filter screen changed by needs, are replaced completely by whole filter core; Filter also can only have one; Pressure gauge also can be pointer pressure, and when Pressure gauge registration is excessive, operating personnel can change filter core; Purchasing ore can not also be established; Filter discharging opening and inner frame also can eccentric settings.
The embodiment of tramp iron separator is as shown in Fig. 2 ~ 4: the concrete structure of tramp iron separator is identical with the tramp iron separator described in above-mentioned each cell size filter embodiment, is not described in detail in this.
